JPS5842862Y2 - Paddy removal device for moisture measurement in paddy dryer - Google Patents

Description

[Detailed explanation of the invention] This invention quickly takes out a part of the selected paddy that does not contain dust or crushed grains, etc. and measures the moisture content without affecting the drying process. The present invention relates to a paddy removal device for moisture measurement in a paddy dryer that can finish dry paddy with a high moisture content.

Conventionally, an opening is provided in the side wall of the grain lifting cylinder located on the lifting path side of the packet belt, a shutter is provided in this opening so that it can be opened and closed freely, and a collecting guide cylinder for collecting grains flying out from the opening is connected to the outside of the opening. A grain lifting machine was developed before this application, for example, in 1973, to facilitate the removal of paddy for moisture content measurement.
It is publicly known as described in Japanese Patent No.-122586.

By the way, the work of taking out samples for moisture content measurement is very important in selecting accurate hot air temperature, air volume, and time required for drying, so it is necessary to collect only selected paddy that is free from dust and crushed grains. If the collected raw material is contaminated with dust, crushed particles, etc., an accurate moisture content cannot be obtained, resulting in under-drying or over-drying.

However, in the conventional equipment of this kind, the dust and crushed grains that were necessarily mixed in with the coarse grains were not removed, and the rice was collected directly from the elevator and used for moisture measurement. Accurate moisture content could not be obtained, and as a result, dry paddy was produced that was under-dried or over-dried, resulting in the disadvantage that high-quality dried paddy could not be obtained.

Therefore, in the present invention, the paddy to be collected is one that is being pumped and has a low rate of contamination with dust and crushed particles, and the paddy that is introduced into the takeout casing through the takeout port during the lifting process is When the paddy passes through a wind-selection chamber installed during introduction, the wind flowing through the elevator automatically separates dust and crushed grains from the paddy, thereby ensuring that only the more carefully selected paddy is introduced into the take-out casing. It is an object of the present invention to provide a paddy extracting device for moisture measurement in a paddy dryer that can measure the moisture content more accurately and easily obtain dried paddy with an appropriate moisture content.

In view of the above, and in order to achieve the above object, the present invention has a configuration in which a confirmation window is opened at an appropriate height position on the front surface of the lifting side of the elevator attached to one side of the dryer body, and a confirmation window is opened in the above confirmation window at an appropriate height. An opening/closing lid with an opening is attached to the opening/closing lid so as to be freely removed, and an extraction casing having an upwardly inclined bottom wall is provided on the outside of the opening/closing lid with the opening opening, and a guide wall is erected on the bottom wall. A wind selection chamber is formed between the take-out port and the guide wall, and a vibration valve whose free end side can come into contact with the opening/closing lid and the guide wall is rotatably supported in the take-out casing above the guide wall. This is a device for taking out paddy for moisture measurement in a paddy dryer. According to this device, the paddy that flies out during the lifting process, which does not affect the drying operation in any way, passes through the removal port and enters the wind sorting chamber. As the paddy passes through, the wind generated in the elevator separates the paddy from dust and crushed grains, and only the selected paddy that is free from dust and crushed grains is introduced into the take-out casing opened by operating the vibration valve. This makes it easier to perform more accurate moisture measurement.When the paddy is not taken out, the protruding paddy is gently caught on the guide wall without being crushed, and then placed on the upwardly sloping bottom wall. It is possible to slide down to the lower part of the elevator quickly without colliding with a movable member, and when the device for taking out paddy for measuring moisture content breaks down, it can be easily replaced.

In the drawing, reference numeral 1 denotes a dryer main body that can quickly dry the paddy by being exposed to drying hot air blown out from the hot air chamber 3 while the paddy is flowing vertically down the drying passage 2; An elevator 4 is attached to one side for lifting and circulating the paddy dried by the dryer main body 1.

Inside the elevator 4, a belt 5 having a large number of packets 6 circumferentially arranged at equal intervals is housed in a suspended manner so as to be able to rotate in the direction of the arrow. A confirmation window 7 is opened at a position approximately at the same height as the person's height for checking whether the belt 5 is re-strung, tensioned, or the working condition is checked.

A removable opening/closing lid 8 is attached to the confirmation window 7 with a locking member 9.

An appropriately sized outlet 10 is opened on the surface of the opening/closing lid 8 formed as described above.
A take-out casing 11 is attached to the outside of the opening/closing lid 8 so as to be fixed or removable for taking out the paddy being transported at any time.

The take-out casing 11 has a hollow interior, and an upwardly inclined bottom wall 12 provided at the bottom of the take-out casing 11 has a guiding wall 13 and a drop opening 14 erected at an appropriate height. are provided adjacent to each other, and a space between the outlet 10 and the guide wall 13 is formed in the wind selection chamber 17.

In the takeout casing 11 above the guide wall 13, there is housed a vibrating valve 15 whose free end is pivoted at one end so that it can come into contact with the opening/closing lid 8 or the guide wall 13, respectively, by vibration operation left and right.

16 is an operation handle for vibrating the vibration valve 15.

Next, its effect will be explained.

Now, in the figure, after paddy is filled and supplied into the dryer main body 1 using the elevator 4, each operating member is started, and as the filled paddy flows vertically down the drying passage 2, dry hot air is blown out from the hot air chamber 3. A circulation drying operation is carried out in which the drying process is carried out using an elevator 4 and flowing back to the main body 1 of the dryer.

By the way, there may be cases where it is desired to take out the paddy outside immediately after it has been dried during the above-mentioned circulation drying operation, measure the moisture content of the paddy, and adjust the drying conditions to appropriate conditions.

In such a case, operate the operating handle 16 to close the vibration valve 1.
When 5 is vibrated from the chain line position to the solid line position in Figure 2, part of the paddy thrown out in the front side from the packet 6, which is being lifted and rotated in the direction of the arrow, will be contaminated with dust and crushed pieces. Together with the grains, they pass through the wind selection chamber 17 from the take-out port 10, and finally pass between the vibration valve 15 and the guide wall 13 to the take-out casing 11.
is about to be introduced into the

By the way, when the above-mentioned paddy passes through the wind selection chamber 17 together with dust and crushed grains, the paddy, dust and crushed grains are separated from each other by the wind selection effect caused by the wind generated by the packet 6 rotating in the elevator. Therefore, only the paddy grains with a heavy specific gravity are introduced into the take-out casing 11, and the dust and crushed grains with a light specific gravity are blown away by the wind.

Therefore, only the selected paddy that does not contain dust or crushed grains is introduced into the take-out casing 11, so if a suitable container (not shown) is placed in the drop port 14, the selected paddy can be used for moisture measurement. It is possible to take out paddy and accurately measure the moisture content without touching the paddy with the operator's hands, thereby allowing the proper paddy drying work to be performed satisfactorily.

When it is not necessary to take out the paddy, if the vibrating valve 15 is set to the position indicated by the chain line in FIG. Thereafter, it flows down along the bottom wall 12 and slides down along the side wall of the elevator 4 to the lower part without colliding with the packet 6 or the like.

Moreover, in the event of a failure due to long-term use, the ejection casing 11 can be easily removed by removing the locking member 9 and replaced with a new one.

Furthermore, when re-stretching or tensioning the belt 5 or checking the working condition, it is sufficient to remove the take-out casing 11 together with the opening/closing lid 9, open the confirmation window 7, and perform the above-mentioned operations.
