Description

The present invention relates to a self-testing device and a self-testing method.

When the harvested grains, such as paddy and wheat, are received at the receiving facility, a portion of them is collected as a sample for voluntary testing. This sample is put into a self-testing device, and quality data of the sample is obtained by measurement using a quality measuring device such as a taste meter or a grain discriminator. Based on this quality data, the grade of harvested grain is determined. Also, based on this grade, each farmer's share of the harvested grain is determined.

The self-testing device is formed by a self-testing section and ancillary equipment including a taste measuring device, a grain discriminator, etc. as a quality measuring section. When performing self-testing, samples are first subjected to pre-processing at the self-testing department. Thereafter, the sample is sent to ancillary equipment, analyzed, and then packed (see, for example, Patent Document 1).

As shown in FIGS. 1 and 2, the self-testing device 1 includes a measuring section 11 that weighs grains such as raw material samples, sorted grains, waste grains, etc., and paddy grains formed by detachable first and second hulling rollers. A self-inspection section 10 having a sliding section 12, a sorting section 13 disposed below the hulling section 12, and an elevating device 14 capable of transporting grain; It includes ancillary equipment 20 including a measuring device 21, a grain discriminator 22, a sample packer 23, and a sample collection section 24, and a chute member 30 that connects the self-inspection section 10 and the ancillary equipment 20.

First, the self-testing section 10 will be explained.

As shown in FIG. 1, the self-inspection section 10 includes a rectangular parallelepiped-shaped housing 15. The housing 15 is formed by a bottom surface portion 16a formed by a bottom plate, an upper surface portion 16b formed by a top plate, and a side surface portion 16c formed by one or more plate-like members. Inside this housing 15, a measuring section 11, a hulling section 12, a sorting section 13, and a lifting device 14 are housed, respectively.

The side surface portion 16c includes a front side surface portion 16d forming the front side of the self-inspection section 10, a back side surface portion 16e forming the back surface, a left side surface portion 16f forming the left side surface, and a right side surface portion 16g forming the right side surface. Equipped with.

The front side section 16d includes an operation section 17a such as a touch panel through which the user inputs instructions regarding self-testing, an input port 17b through which the user inputs grain, and a result display section that prints information based on signals output from the measuring equipment. 17c.

An opening 18 is formed in the upper part of the right side part 16g or the left side part 16f (in this embodiment, the upper part of the left side part 16f), and one end of a chute member 30, which will be described later, is connected thereto.

The operating section 17a is electrically connected to a control section (not shown) and accommodates the control section inside. The control unit receives instructions from the operation unit 17a, and selects grains to be subjected to self-inspection, performs measurements in the weighing unit 11, operates the hulling unit 12, operates the sorting unit 13 that sorts grain samples, and controls the lifting device. 14, the operation of the opening/closing device 31, the operation of the capture unit 25 when collecting a size sample, etc. Note that in this specification, the measuring device refers to a device included in the self-testing device 1.

As shown in FIG. 2, the weighing section 11 includes a first weighing section 11a that weighs the raw grain input into the self-inspection section 10 from the input port 17b, and a first weighing section 11a that weighs the raw grain input into the self-inspection section 10 from the input port 17b, and a first weighing section 11a that weighs the raw grain that has been input into the self-inspection section 10 from the input port 17b. A second measuring section 11b for measuring. The first measuring section 11a and the second measuring section 11b are arranged to face each other in the horizontal direction inside the self-inspection section 10. A first discharge chute 32 is provided at the lower part of the first measuring section 11a, and conveys the grains inputted from the input port 17b and weighed by the first measuring section 11a to the conveying unit 19. A second discharge chute 33 is provided at the bottom of the second weighing section 11b, and transports the sorted grains that have been sorted by the sorting section 13 and weighed by the second weighing section 11b to a lifting device 14, which will be described later.

The transport unit 19 is a unit connected to the right side surface portion 16g of the housing 15 on the side where the opening 18 is not provided. The transport unit 19 transports the raw material grains weighed by the first measuring section 11 a to the hulling section 12 located above the self-inspection section 10 .

The hulling section 12 is a pair of hulling rollers (not shown) that are formed by a first hulling roller (not shown) and a second hulling roller (not shown) having approximately the same external shape as the first hulling roller. It is formed by sliding rollers. The first hulling roller and the second hulling roller face each other and are each removably attached to the rotating shaft. Moreover, the roll gap when the first hulling roller and the second hulling roller are attached to the rotating shaft can be arbitrarily set and changed as long as the hulling process can be performed. When sorting grain samples with relatively large grains, such as soybeans, at least one of the first hulling roller and the second hulling roller is removed.

The sorting section 13 is provided at the lower part of the hulling section 12, and sorts grain samples according to grain size. When using paddy as a grain sample, the sorting unit 13 sorts the grain sample into waste grains and regular grains. Further, when sorting a relatively large grain sample such as soybean, the sorting section 13 sorts the grain sample into waste grains, large grains, medium grains, and small grains. A third discharge chute 34 is provided at the bottom of the sorting section 13, and conveys the sorted grains sorted by the sorting section 13 to the second weighing section 11b.

The lifting device 14 is a long shaft member having a longitudinal axis in the vertical direction, and has an opening 18 inside the self-inspection section 10 so as not to come into contact with the measuring section 11, the hulling section 12, and the sorting section 13. This is a lift device that is installed upright in the vicinity of the left side surface portion 16f in which a is formed. The lifting device 14 includes a storage member 14a that receives the sorted grains conveyed from the second weighing section 11b, and a rod-shaped member 14b to which the storage member 14a is movably attached. Further, upon receiving the actuation signal from the control section, the lifting device 14 moves the storage member 14a in the extending direction of the rod-shaped member 14b (upward direction of the Y-axis).

The storage member 14a is a member with an inclination, and can store not only grain samples as large as paddy, but also relatively large grain samples such as soybeans. A shutter member 14c having the same size as or smaller than the opening of the opening 18 is provided on the lower side of the inclination of the housing portion. Further, the shutter member 14c of the storage member 14a attached to the rod-shaped member 14b faces the left side surface portion 16f, and between the shutter member 14c and the left side surface portion 16f, the grain sample falls into the self-inspection section 10. The shutter member 14c and the left side surface portion 16f are close to each other to the extent that they do not touch each other, or the shutter member 14c and the left side surface portion 16f are in contact with each other.

The rod-shaped member 14b is a member that functions as a so-called rail, and prevents the storage member 14a from rotating inside the self-inspection section 10. allow you to move. Since the movement of the storage member 14a in the extending direction of the rod-shaped member 14b is guided by the rod-shaped member 14b, the storage member 14a can be moved back and forth from the lower part to the upper part of the self-inspection section 10.

When the storage member 14a moves to the upper end of the rod-shaped member 14b, the lower end of the shutter member 14c is located at the same position as the lower end of the opening 18 or higher than the lower end of the opening 18. Therefore, when the shutter member 14c opens, the grain sample is carried out to the chute member 30 through the opening 18. Since the lifting device 14 is formed in this manner, the grain sample can be efficiently transported to the chute member 30 through the opening 18.

Next, the auxiliary equipment 20 will be explained with reference to the drawings.

As shown in FIGS. 1 and 2, the auxiliary equipment 20 includes a taste measuring device 21, a grain discriminator 22, a sample packer 23, and a sample collecting section 24. The auxiliary equipment 20 is disposed close to the left side surface portion 16f in which the opening 18 is formed, and is disposed in the horizontal direction (in the present embodiment, the X-axis direction) of the self-inspection section 10. Further, the auxiliary equipment 20 includes a sample packer 23 and a sample collection section 24 arranged vertically from the self-inspection section 10 toward the X-axis direction, and a taste measuring device 21 and a grain discriminator 22 arranged in this order. has been done.

The taste measuring device 21 is a device for measuring the ingredients, taste, etc. of the sized grains, and is mainly used to measure the internal appearance quality of the sized grains. The taste measuring device 21 includes a touch-operable monitor section on which measurement results are displayed, a connecting section 21a provided at the top that connects to the chute member 30, and a measuring section 21a that measures the quality of the sized particles and sends the results to the self-inspection section 10. It is formed by a measuring section that measures the size of the particles, and a particle size regulating and discharging section provided on the lower surface. The connecting portion 21a connects to one end of a chute member 30, which will be described later. Further, a thrower 21b is arranged at the lower part of the particle size discharging section (in the downward direction of the Y axis), and the particle size discharging section is connected to the thrower 21b and connected to the sample packer 23 via the discharge tube 21c of the thrower 21b. .

The grain discriminator 22 is a device that determines the quality of grain size, and is mainly used to measure the appearance quality of grain size by determining colored grains, dead rice, cracked grains, etc. be. The grain discriminator 22 includes a touch-operable monitor section on which measurement results are displayed, a grain receiving section 22a provided at the top, and a measuring section that discriminates the grain quality and sends the results to the self-inspection section 10. and a grain discharge section provided on the lower surface. The grain receiving portion 22a is connected to a tubular member 26, which will be described later, and receives the sorted grains collected by the tubular member 26. Further, the grain discriminator 22 is arranged in front of the taste measuring device 21, that is, in the downward direction of the Z axis, and is formed and arranged separately from the taste measuring device 21.

The sample packer 23 is disposed between the taste measuring device 21 and the grain discriminator 22 and the self-inspection section 10, and collects grains to be stored, waste grains, sized grains, etc. that are carried out from the self-inspection section 10. It is packaging equipment. Further, a sample collecting section 24 is arranged on the upper surface of the sample packer 23.

The chute member 30 connects the self-inspection section 10 and the ancillary equipment 20, receives the grain sample carried out from the storage member 14a through the opening 18 of the self-inspection section 10, and transfers the grain sample from the self-inspection section 10 to the ancillary equipment 20. A tubular member for transporting grain samples. The chute member 30 connects the opening 18 formed in the upper part of the left side surface 16f of the self-inspection section 10 and the auxiliary equipment 20, and falls down from the opening 18 toward the auxiliary equipment 20. In other words, one end of the chute member 30 is connected to the vicinity of the opening 18 of the self-inspection section 10, and the other end of the chute member 30 is connected to the connection part 21a of the taste measuring device 21. An opening/closing device 31 is provided upstream of the chute member 30 to control the flow of the grain sample carried out from the opening 18 to the chute member 30 . In addition, the sample collecting section 24 is connected to an arbitrary point between one end and the other end of the chute member 30, and the chute member 30 has an inlet and an inlet through which the sorted grains captured by the sample collecting section 24 pass. A hole is provided. Further, the chute member 30 has a switching mechanism (not shown), and switches between the flow path to the taste measuring device 21 and the flow path to the sample packer 23 according to the user's selection. Thereby, the grain sample flowing down the chute member 30 is distributed to the taste measuring device 21 and the sample packer 23.

The opening/closing device 31 is formed by an elevating member provided upstream of the chute member 30, functions as a shutter, and is controlled by a control section. The opening/closing device 31 may be of any type, such as vertical opening/closing, horizontal opening/closing, double opening, etc., as long as it functions as a shutter.

The sample collection unit 24 is a device that is connected to the chute member 30 and that collects a part of the sorted grains flowing down the chute member 30 and conveys it to the grain discriminator 22. As shown in FIGS. 3(A) and 3(B), the sample collection unit 24 includes a trapping unit 25 that captures the regular grains inside a hollow rectangular parallelepiped housing, and a grain discriminator 22 to collect the captured regular grains. and a tubular member 26 that is conveyed to. In addition, in FIG. 3, the casing is virtually represented by a two-dot chain line.

The trapping section 25 is formed by a plate member 25a arranged in the internal space of the chute member 30, a connecting member 25b connected to the trapping plate 25c, and a trapping plate 25c that traps the sorted grains.

The plate-like member 25a is a plate-like member that can come into contact with the inner surface of the chute member 30. The plate member 25a has a size that allows it to be easily accommodated in the chute member 30.

The connecting member 25b is a member having a long axis, and one end thereof is connected to the capturing plate 25c. The other end is connected to the control section.

The capture plate 25c is a plate-like member connected to the connecting member 25b at an angle of elevation with respect to the downstream direction of the graded particles and for capturing the graded particles. The capture plate 25c may have a bent portion. For example, by a first plate-like member parallel to the downstream direction of grain size adjustment, and a second plate-like member forming an arbitrary angle greater than 0 degrees and smaller than 180 degrees with respect to the first plate-like member when viewed from the front. may be formed.

As shown in FIG. 3(C), the maximum length (L1) of the trapping part 25 that protrudes into the flow path at the time of size-sorting collection (the length from the outer surface of the plate-like member 25a to the entrance/exit hole of the chute member 30) is as follows: It is shorter than the length (L2) of the inner diameter of the chute member 30. Therefore, when collecting the sized sample, the capturing section 25 does not completely block the flow path, and it is possible to ensure both the collection of the sized sample and the flow of the sized particle to the taste measuring device 21. Further, the diameter of the plate member 25a is larger than the diameter of the entrance/exit hole. For this reason, as shown in FIG. 3(B), when grain samples are not collected, the lower surface of the plate member 25a partially contacts the inner surface of the chute member 30, thereby closing the entrance/exit hole and allowing the grain sample to be collected. It is possible to prevent the sample from passing through the entrance/exit hole and being transported into the sample collection section 24.

The control unit controls movement of the capture unit 25 in the direction of the internal space of the chute member 30. When collecting the size sample, the control unit sends the size sample collection signal to the capture unit 25, and the capture unit 25, which has received the size size sample collection signal, moves to the size flow path of the chute member 30 and sorts the size. Capture. After capturing the sized particles, the capturing section 25 returns from the flow path and carries out the sized particles into the inside of the casing. The control unit instructs the capturing unit 25 to perform a sampling operation a preset number of times, one or more times, in order to collect the required amount of grains for measurement with the grain discriminator 22.

The tubular member 26 is a member used to convey the sorted grains carried out into the inside of the casing to the grain discriminator 22. As shown in FIGS. 3A and 3B, the tubular member 26 is provided at the lower part of the sample collection section 24, and has a funnel (or reverse tapered) section 26a and a tubular section 26b. One end thereof is connected to the funnel portion 26a. The tubular portion 26b extends down to the grain discriminator 22, and the other end of the tubular portion 26b is connected to the grain receiving portion 22a of the grain discriminator 22.

Since the sample collection section 24 has a housing, the sample collection section 24 can be placed above the sample packer 23, and the arrangement of the sample collection section 24 on the sample packer 23 is stabilized. Further, it is possible to prevent the sorted particles collected by the chute member 30 from scattering to the outside of the casing. Further, since the tubular member 26 has a funnel (or inversely tapered) shape, the sorted particles discharged into the interior of the casing can be efficiently collected.

In addition, since the control unit instructs the capture unit 25 to perform one or more sampling operations, it is possible to prevent the grain size from being caught between the capture unit 25 and the chute member 30.

As shown in FIG. 2, the height (L3) to the lower end of the opening 18 of the self-inspection section 10, the height (L4) of the sample packer 23, the height (L5) of the sample collection section 24, and the taste The relationship between the total height (L6) of the measuring device 21 and the thrower 21b is expressed as L3>(L5+L6)>L4. Therefore, when the chute member 30 is connected to the self-inspection section 10 and the auxiliary equipment 20 at both ends, the chute member 30 is connected by falling down from the opening 18 of the voluntary verification section 10 toward the ancillary equipment 20. With such a configuration, the grain sample carried out to the chute member 30 flows down the chute member 30 from the self-inspection section 10 toward the auxiliary equipment 20 due to its own weight. In addition, since the tubular part 26b of the sample collecting part 24 falls down and connects to the grain receiving part 22a of the grain discriminator 22, the sorted grains collected by the tubular member 26 can be efficiently transferred to the grain discriminator 22. Can be transported.

Next, a self- testing method according to this embodiment will be explained.

First, a case where paddy is used as a grain sample will be explained.

First, as shown in FIGS. 1 and 2, the auxiliary equipment 20 is placed in advance in the horizontal direction of the self-inspection section 10. Further, the opening 18 provided in the upper part of the self-inspection section 10 and the incidental equipment 20 are connected to each other via the chute member 30.

Next, the user operates the operation unit 17a to select paddy as the grain to be self-inspected. If a self-inspection of other grains such as soybeans has been carried out before the self-inspection of paddy, the self-inspection process for the other grains and paddy is switched in response to an instruction from the operation unit 17a.

Next, the user puts the paddy into the input port 17b of the self-inspection section 10. The first weighing section 11a shown in FIG. 2 weighs the paddy input from the input port 17b. Then, the conveying unit 19 conveys a part of the paddy weighed by the first measuring section 11a to the hulling section 12. After conveyance, the first hulling roller and the second hulling roller remove part of the rice, and the sorting section 13 sorts it into waste grains and regular grains. The second weighing section 11b weighs waste grains and sized grains. The grain sample weighed in the second weighing section 11b is conveyed from the second weighing section 11b to the lifting device 14 through the second discharge chute 33. The weighing unit 11 outputs various measured data to the result display unit 17c of the self-testing unit 10 shown in FIG.

While some of the paddy is hulled, etc., the self-inspection section 10 discharges the unhulled paddy (saved paddy) from the second discharge chute 33 to the storage member 14a waiting at the lower part of the self-inspection section 10. The storage member 14a is moved to the upper part of the self-inspection section 10 by the lifting device 14 that receives the signal from the control section.

After the storage member 14a moves to the upper part of the self-inspection section 10, the shutter member 14c of the storage member 14a opens, and the preserved paddy is carried out to the chute member 30. The stored paddy that has been carried out flows down a chute member 30 that connects the self-inspection section 10 and the auxiliary equipment 20. At this time, if the grain size measurement by the taste measuring device 21 is not completed, the opening/closing device 31 provided upstream of the chute member 30 is lowered, and the preserved paddy is stored upstream of the chute member 30. After the grain size measurement with the taste measuring device 21 is completed and the grain size is packaged in the sample packer 23, the opening/closing device 31 is raised and the preserved rice flows down the chute member 30. In addition, after carrying out the preserved paddy to the chute member 30, the lifting device 14 moves to the lower part of the self-inspection section 10.

The switching mechanism switches the flow path of the chute member 30 to the flow path from the taste measuring device 21 to the sample packer 23, and conveys the stored paddy flowing down the chute member 30 to the sample packer 23. After that, the sample packer 23 packages the preserved paddy.

After the preserved paddy flows down the chute member 30, the lifting device 14 transports the waste grains weighed in the second measuring section 11b to the upper part of the self-inspection section 10, and carries them out to the chute member 30 as in the case of the preserved paddy. do. The waste particles flowing down the chute member 30 are conveyed to the sample packer 23, and the sample packer 23 packages the waste particles. In addition, after carrying out the waste grains to the chute member 30, the elevating device 14 moves to the lower part of the self-inspection section 10.

After the sized grains flow down the chute member 30, the lifting device 14 transports the sized grains weighed with a scale to the upper part of the self-inspection section 10, and transports them from the lifting device 14 in the same way as in the case of preserved paddy and waste grains. It is carried out to the chute member 30.

At this time, the sorted grains flowing down the chute member 30 are not conveyed to the sample packer 23 by the switching mechanism, but flow down to the taste measuring device 21.

Furthermore, before the grains flow down to the taste measuring device 21, the capture section 25 that has received the signal from the control section slides into the grain size flow path in the chute member 30 and projects into the grain size flow path. When the capture portion 25 protrudes into the flow path, it does not completely block the flow path. This ensures that the sized particles flow down to the taste measuring device 21 even when collecting the sized sample.

After a part of the sized particles contacts or accumulates on the capture plate 25c of the capture unit 25 protruding into the flow path, the capture unit 25 repeats sliding a preset number of times in accordance with a signal from the control unit. As a result, the sorted particles are accommodated inside the sample collection section 24 and dropped into the tubular member 26.

The sorted grains collected by the sample collection section 24 pass through the tubular member 26 and flow down to the grain discriminator 22.

The quality of the sorted grains conveyed to the grain discriminator 22 is measured. After the measurement, the grain discriminator 22 outputs the measurement data to the result display section 17c of the self-inspection section 10. The grains that have been measured by the grain discriminator 22 are discarded to the outside of the grain discriminator 22 from a grain discharge section provided on the lower surface.

On the other hand, the taste of the sorted grains conveyed to the taste measuring device 21 is measured. After the measurement, the taste measuring device 21 outputs the measurement data to the result display section 17c of the self-testing section 10. The sorted grains that have been measured by the taste measuring device 21 are conveyed to the sample packer 23 by the thrower 21b attached to the taste measuring device 21 and packaged. The taste measuring device 21 and the grain discriminating device 22 forming the auxiliary equipment 20 are formed separately and independently. Therefore, even if the grain discriminator 22 has not finished measuring the grain size, the grain size can be transported from the taste measuring device 21 to the sample packer 23.

After that, each measurement data output from the taste measuring device 21 and the grain discriminator 22 to the result display section 17c of the self-testing section 10 is displayed on the result display section 17c together with the weighing data from the weighing section 11, so that the user can will be printed, etc., and the self-inspection of paddy will be completed.

Self-test sample: soybean

Next, in order to explain a self-testing method when relatively large grains are used as a grain sample, a case where soybeans are used as a grain sample will be explained as an example.

First, at least one of the first hulling roller and the second hulling roller is removed from the hulling section 12 of the self-inspection section 10 in advance.

Next, the user operates the operation unit 17a shown in FIG. 1 to select soybeans as the grain to be self-verified. If the self-verification of other grains such as paddy has been carried out before the self-verification of soybeans, the self-verification process for the other grains and soybeans is switched in response to an instruction from the operation unit 17a. When soybeans are selected, the operation unit 17a displays an instruction to remove at least one of the first hulling roller and the second hulling roller on the connected display device. Following this display, the user can prevent mistakes in removing at least one of the first hulling roller and the second hulling roller.

Next, the user inputs soybeans into the input port 17b of the self-inspection section 10. The first measuring section 11a shown in FIG. 2 weighs the soybeans input from the input port 17b. Then, the transport unit 19 transports a portion of the soybeans weighed by the first measuring section 11a to the hulling section 12. After being transported, some of the soybeans pass through the hulling section 12. Thereafter, the sorting section 13 sorts the grains into three categories: large grains, medium grains, and small grains. The second weighing section 11b weighs the sorted soybeans for each particle size. The measuring section 11 outputs various measured data to the result display section 17c of the self-testing section 10.

While some of the soybeans are sorted, the self-inspection section 10 discharges unsorted soybeans (preserved soybeans) from the second discharge chute 33 into the storage member 14a waiting at the lower part of the self-inspection section 10. Thereafter, similarly to the case of preserved paddy, the preserved soybeans are conveyed to the upper part of the self-inspection section 10 by the lifting device 14, and are carried out to the chute member 30, and the soybeans flow down the chute member 30. At this time, if the measurement by the auxiliary equipment 20 is not completed, the opening/closing device 31 provided upstream of the chute member 30 is lowered, and the preserved soybeans are stored upstream of the chute member 30. After the various measurements in the auxiliary equipment 20 are completed and the soybeans are packaged in the sample packer 23, the opening/closing device 31 is raised and the stored soybeans flow down the chute member 30. In addition, after carrying out the stored soybeans to the chute member 30, the elevating device 14 moves to the lower part of the self-inspection section 10.

The switching mechanism switches the flow path of the chute member 30 to the flow path from the taste measuring device 21 to the sample packer 23, and transports the stored soybeans flowing down the chute member 30 to the sample packer 23. After that, the sample packer 23 packages the preserved soybeans.

As in the case of preserved soybeans, the lifting device 14 transports the soybeans sorted into large, medium, and small grains to the chute member 30, the chute member 30 transports the soybeans to the sample packer 23, and the sample packer 23 separates the soybeans into three Soybeans are packaged according to particle size sorted into categories.

Thereafter, the measurement data measured by the measurement section 11 is displayed on the result display section 17c, and the user prints the data, thereby completing the self-inspection of soybeans.

As described above, the self-testing device 1 according to the present embodiment includes the lifting device 14, the auxiliary equipment 20 arranged horizontally in the self-testing section 10, and the opening 18 of the self-testing section 10. It has a chute member 30 that connects downwardly toward the auxiliary equipment 20. Therefore, it is possible to suppress the possibility that grains of large-diameter grain samples containing soybeans will break. Further, there is no need to separately prepare a self-inspection device for relatively large grains such as soybeans. In addition, since the tubular part 26b of the sample collecting part 24 is connected down to the grain receiving part 22a of the grain discriminator 22, the sorted grains collected by the tubular member 26 can be efficiently transferred to the grain discriminator 22. It can also be transported.

Furthermore, the self-testing device 1 according to the present embodiment is capable of both flowing the sorted grains to the taste measuring device 21 and collecting the necessary amount of sorted grains for measurement with the grain discriminator 22. , it is possible to improve work efficiency.

Further, the sorted grains measured by the taste measuring device 21 are conveyed to the sample packer 23 by the thrower 21b, so that the working time can be shortened.

Although the self-testing device 1 according to the present embodiment has been described above as an example, the self-testing device 1 is not limited to the above embodiment, and various modifications and applications are possible.

For example, although not shown, the sample collection section 24 may be provided with a sensor that detects a particle being caught between the capture section 25 and the chute member 30. When the sensor detects that the grain size is caught, the notification mechanism visually indicates the grain size jam to the user on the result display section 17c, or issues an alarm, and automatically stops the self-inspection.

Further, as shown in FIG. 4, the sample collection section 24 may include an aspirator 24a. The aspirator 24a can separate and remove the sized grains, dust, etc. that are transported to the grain discriminator 22, and more accurate measurement results can be obtained.

Further, in this embodiment, the grain discriminator 22 is placed in front of the taste measuring device 21, but the placement may be changed arbitrarily as long as self-testing can be performed appropriately. .

Further, although the configuration in which the capturing section 25 includes the capturing plate 25c has been illustrated, the present invention is not limited to this. For example, if the size is such that it can be easily stored in the chute member 30, and the size can capture the sorted particles and pass through the inlet/outlet hole and trap the captured particles in the sample collection section 24, the trapping plate 25c is a bucket-shaped one. It may also be a container.

Further, one end portion of the connecting member 25b may be connected to one surface of the plate member 25a instead of the capturing plate 25c.

Further, a second plate member having a larger diameter than the entrance/exit hole may be provided on the connecting member 25b or the capture plate 25c on the outside of the chute member 30. The connecting member 25b or capture plate 25c defined by the first plate member and the second plate member also functions as a spacer. Further, it is also possible to prevent the trap 25 from falling into the flow path.

Furthermore, in this embodiment, a mode has been described in which the tubular member 26 is integrated with the tubular portion 26b, but the tubular portion 26b may be provided separately from the tubular member 26. As long as the sorted grain can be conveyed to the grain discriminator 22, its shape, material, etc. are not particularly limited, and for example, it may have a tubular shape and be made of a plastic material.
