Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powdery or granular material feeding device suitable as a fertilizer application device for a rice transplanter, and more particularly to a rice transplanter capable of supplying chemicals such as insecticides and bactericides in addition to fertilizers. The present invention relates to a technology for rationalizing the arrangement structure of a hopper suitable for being mounted on a traveling machine body such as the above, or the structure of a hopper or a feeding mechanism suitable for six rows.

[0002]

2. Description of the Related Art For example, as a powder and granular material feeding device used for a rice transplanter as a fertilizer applying device, those shown in Japanese Utility Model Laid-Open No. 59-618 and Japanese Patent Laid-Open No. 6-141643 are known. . In the former publication, a large main fertilizer tank is arranged on the rear side of the driver's seat, and from this main fertilizer tank, an auxiliary tank for each article is provided on top of the feeding mechanism installed for each article. The fertilizer is distributed and supplied to, and is, so to speak, an integrated tank structure. In the latter publication, a single-row hopper is arranged above a feeding mechanism provided for each row, which is a row-row tank structure.

[0003]

In the integrated tank structure,
One large fertilizer tank is enough, the number of parts can be reduced, and the feeding mechanism part can be configured relatively lightly to prevent overloading of the planting part, but a large tank is placed at the rear of the driver's seat. By doing so, there is a concern that the overall length of the machine body is likely to be long, or that the flow is unbalanced or is easily clogged at the part where the granular material is branched from one pipeline to a plurality of pipelines.

Further, in each row tank structure, the fertilizer tank can be small in size, which is unlikely to be a factor for increasing the overall length of the machine body, and even if the number of planting rows is different, the fertilizer tank and the feeding mechanism can be made the same. It has the convenience that it can easily be applied to odd-row planting models such as 3-row and 5-row, but it has the trouble of assembling the feeding mechanism and hopper for each row. Therefore, this is a problem that cannot be ignored with the main model for even-numbered articles, which has a large number of units sold, such as 4-row planting or 6-row planting, which does not need to be configured for each article, and there is room for improvement in terms of the above-mentioned trouble.

An object of the present invention is to further rationalize the layout of the hopper and the feeding mechanism, or to make it possible to commonly use both even-row planting and odd-row planting, while supplying both fertilizer and chemical powder. The point is to make the particle feeder smaller.

6 and the engaging arm 61 is removed from the engaging projection (not shown), the fertilizer feeding roll R is exposed, and an open state convenient for maintenance of that portion appears.

As shown in FIG. 4, four discharge hoses 5 are provided.
All of 4, 55 are routed downward through a through hole 60 formed at the rear end of the rear wheel fender 59, and the discharge hose can be smoothly routed to smoothly slide down for fertilizer discharge. Is done. Further, in order to easily form the through hole 60 as needed after the fender is formed, an arcuate notch groove is formed in advance when the fender is formed by a mold or the like.

Each clutch (not shown) which can freely transmit and transmit power to one planted transmission case 8 (a pair of rotating cases 9), and each clutch for performing transmission and transmission interruption operation on each clutch. A clutch lever (not shown) is provided. As shown in FIG. 7, the L-shaped operation arm 36 is swingably supported around the axis P1 of the fixed portion of the fertilizer feeding section K, and the end of the operation arm 36 is engaged with the shift member 31. Each wire clutch lever and the operation arm 36 are connected by a wire 38.

As a result, for example, when each thread clutch lever of the right planted transmission case 8 is operated to the transmission cutoff side and each thread clutch of the right planted transmission case 8 is operated to cut off the transmission, the right planted transmission case 8 is transmitted. The pair of rotating cases 9 of the case 8 are stopped, the two right planting strips are not planted, and the drive shaft 1 of the fertilizer feeding section K corresponding to the two right planting strips.
5 stops, and the fertilizer supply to the two right planting lines is stopped.

As shown in FIGS. 5 and 3, the switching plate 41 is supported on the funnel portion 26 so as to be swingable around the horizontal axis P2, and the discharge hose 54 is provided downward from the lower side of the switching plate 41. It has been extended. Switching plate 4 during normal planting work
1 is operated in the closed position shown by the solid line in FIG. 5, and the fertilizer from the fertilizer hopper 17 is fed to the funnel portion 26. Blower 2 when normal planting work is completed.
0 and the seedling planting device 7 (PTO shaft 29) are stopped and the switching plate 41 is operated in the open position, the fertilizer hopper 1
The fertilizer remaining in No. 7 enters the discharge hose 54 and is discharged.

By the way, the feeding section K has two funnel sections 2
6 and 26 and two sets of roll cases 16 corresponding to the width thereof are integrated into a two-row type, that is, a two-row feeding section K2 is basically used, but two feeding sections K in the center of the left and right are for six rows. Therefore, one of the funnel portions 26 is made nonfunctional.

That is, as shown in FIG. 8, one set of the three partial rolls r1 to r3 is omitted, and the two fertilizer hoppers 21 and 21 at the center of the left and right have one roll of the partial rolls r1 to r3. An inclined bottom surface 21a is additionally formed so as to have a supply port width for a set, and this is referred to as a single-line feeding portion K1. Therefore, only one fertilizer application hose 19 is attached to the one-line feeding section K1, and the capacity of the two central fertilizer hoppers 21 is set to half of that of the hoppers 17 on the left and right ends, and a total of four sets of feeding are provided. Part K2, K
The fertilizer application A for 6 articles is composed of 1, K1 and K2.

That is, as shown in FIG. 9, the hopper 17 of the two-row feeding portion K2 is provided with a front projecting portion that wraps around the lateral side of the driver's seat, that is, the hopper 21 with the front-rear width in the left-right center It is about twice as large as the original one. Then, as shown in FIG. 4, in the two sets of the single-line feeding portions K1 arranged in parallel immediately after the driver's seat 23, the vertical surface 21A on the front side of the hopper 21 is formed to be a substantially vertical rising surface. is there. Further, each hopper 17, 21 is formed in a downward constricted shape in a side view, and an auxiliary step 75, which is convenient at the time of replenishing fertilizer, is arranged near the lower side of the two-row hopper 17, 17 at the left and right ends. I am doing it.

The details of the drug delivery device C will be mainly described below. As shown in FIG. 5, the drug roll case 84
The brush lever 97, the switching lever 98, and the lid 87, which are installed in the vehicle, are all configured so that they can be operated by extending their hands from the operation unit 5.

As shown in FIGS. 4 and 11, the fertilizer applicator A and the chemical applicator C are both arranged such that the support frame 14 is sandwiched between the front and the rear, and the powder granules are used by combining the frame and the aggregate arrangement. The size and cost of the supply device are reduced. Further, since both the devices A and C are attached to the support frame 14 by using the tightening bolts 101, the bolt and the bolt hole of the support frame 14 can be used in common to reduce the cost, and the medicine applying device C can be used as the fertilizer applying device A.
There is an advantage in that the rear side can be seen through between the left and right feeding portions L and L, and the empty space can be used for other purposes.

That is, the left and right center of the fertilizer application device A is aligned with the left and right center of the drug application device C, and the medicine roll case 84
Exit 85 in the roll case 16 and entrance / exit 4 in the roll case 16
The left and right positions of 8 are substantially aligned with each other so that the medicine can be transferred smoothly.

In the medicine applying device C, by adjusting the connecting position of the interlocking rod 92 to the supplying arm 91, the amount of medicine applied to the field along with the progress of the rice transplanter is adjusted by the medicine supplying roll 8 per one seedling.
It is possible to set such that the amount of the medicine that has entered the one concave portion 83a of No. 3 is supplied, and the spraying accuracy is improved. It should be noted that the amount of medicine applied per one seedling is one concave portion 83a.
It is also possible to set the above or below.

Since the amount of the chemical sprayed per one seedling is extremely small, when the one recessed portion 83a is fed out per one seedling, the feeding amount error tends to be large. Therefore, if the dose is set to be one concave portion 83a or more per one seedling, the total number with respect to the error number is increased, and as a result, the error can be reduced.

As shown in FIG. 18, the medicine feeding roll 8
3, the circumferential length (angle) a of the recess 83a is longer than the circumferential length (angle) b of the non-recessed portion, and the drug discharged from the recess 83a of the drug feeding roll 83 is the drug roll. The case 84 is configured so that it is rebounded and transferred to the outlet 85. As a result, it is possible to reduce the possibility that the medicine is dispersed when it drops and is in an intermittent spraying state, and the spraying state is as continuous as possible.

As described above, the power to the medicine applying device C is taken from the planting system (PTO system), and when a fixed amount is sprayed over the planted area, only adjustment between the plants is required. Easy to adjust the quantity.

When the interlocking rod 92 for driving the drug delivery device C is pivotally attached in the middle of the interlocking rod 37, the interlocking rod 9
Since No. 2 will be attached after the assembling of the linking rod 37, as shown in FIG.
The interlocking rod 92 is set to be arranged outside the linking rod 37.

Since the roll shafts 83b of the four medicine feeding portions L ₂ , L ₁ , L ₁ , and L ₂ are all aligned on a straight line, as shown in FIG. As shown in FIG. 20 (a), the main shaft 83b is formed, and as shown in FIG. 20 (a), the three divided roll shafts 8 straddle the adjacent drug delivery rolls 83, 83.
It can be configured as 3b. By appropriately using these means, the structure can be simplified, the space can be reduced, the cost can be reduced, and the error due to the backlash can be reduced. Also, disassembly and assembly are easy.

As shown in FIG. 15, the medicine applying brush shaft 88a.
Since the switch shaft 89a and the switching shaft 89a are disposed above and below the medicine feeding roll 83, the medicine feeding roll 83 has a large opening 8 in the maintenance posture shown in FIG.
Since it can be seen from 6, there is an advantage that the rotating operation of the rolling 83 is small when cleaning. Also, the medicine feeding roll 8
3 is formed for each line so as not to interfere with the partition wall on the left and right, if the roll shaft 83b is pulled out to the left and right in advance, the medicine feeding roll 83 from the large opening 86.
Can be replaced. If the brush 88 is in the retracted posture or the path switching plate 89 is in the maintenance posture, the lid 8
7 can not be installed, so both of them 88, 8
There is an advantage that it is possible to prevent malfunctions in advance by noticing that 9 is not in a normal working state.

As shown in FIGS. 15 and 16, a large opening 86 is formed.
Since the slanted bottom surface 84b exists on the bottom surface, the slanted bottom surface 84b allows the medicine to be discharged without remaining, while the three protrusions 84c improve the adhesion to the lid 87 and make it difficult to remove. . Also, the drug roll case 84
Is a resin-integrated product that is molded or injection-molded, and has a simple structure and cost reduction, as well as excellent waterproofness and airtightness (a point that prevents the ejection of powdered particles such as chemicals). It is configured.

As shown in FIG. 13 and FIG. 16, the brush lever 97 and the switching lever 98 are both set in a posture in which they are substantially parallel and vertically oriented during the drug dispensing work, but are separated from each other during the other work. It is designed to be oriented. Therefore, both levers 97, 9
By visually recognizing the posture of No. 8, it is possible to know whether or not it is in the normal position, and it is possible to make a judgment of erroneous operation prevention. or,
As shown in FIG. 16A, both levers 97 and 98 during the drug dispensing work are accommodated within the front-rear width of the drug roll case 84 and are operated in an unintended direction by being caught by a part of the machine body or an operator. I try not to cause it.

As shown in FIG. 15, the brush lever 97 and the switching lever 98 are mounted on the left and right sides of the medicine roll case 84 on opposite sides of each other. Therefore, since they do not interfere with each other, the lever length is increased so that the lever can be operated easily with a light force. Further, the medicine scraping brush 88 whose posture is changed by the rotational movement can be detached from the medicine roll case 84 by pulling out the brush shaft 88a in the left-right direction.

As shown in FIG. 19, adjacent brush bundles 88
The distance w between b and 88b is smaller than the diameter d of the drug particles and larger than the radius d / 2 of the drug particles, d>
The dimensions are set so that the relationship of w> d / 2 holds.
Thereby, the medicine can be prevented from spilling out from the gap between the brush bundles 88b and 88b during the stop, and the medicine stuck in the brush bundle 88b can be prevented.
The spread of b to the left and right facilitates the flow out during the operation of the drug administration device C.

The medicine scraping brush 88 is formed in a bilaterally symmetrical shape, and if it deforms due to contact with the medicine feeding roll 83 rotating in a certain direction, it can be mounted upside down to suppress the deformation and double the service life. Is reasonable.

As shown in FIGS. 5 and 16, the medicine scraping brush 88 has its tip directed toward the roll axis Y, and the case opening 65 which is a medicine flow path from the medicine hoppers 80 and 81 is constricted. It is arranged to be inclined with respect to the medicine roll case 84 so as to be round. This makes it easier for the medicine particles, which are partly protruding from the recess 83a without being able to enter the recess 83a, to be scraped off by the brush 88 to escape.

As shown in FIG. 3, a two-row drug hopper 80 is provided.
Has a capacity twice as large as that of the single-row chemical hopper 81, but has the same height, so that the reduction of the chemicals is almost the same, and it is easy to visually confirm the remaining amount.

As shown in FIGS. 5 and 16, the upper portion of the medicine feeding roll 83 rotates in the direction toward the large opening 86. Therefore, when the medicine is discharged from the large opening 86, the roll 83 is rotated. The medicine remaining thereon can be taken out without difficulty and the medicine scraping brush 88 can be arranged on the large opening 86 side of the medicine feeding roll 83, so that the maintainability is also good.

In the powder and granular material feeding device shown in FIG. 5 and FIG. 21, which will be described later, since the large opening 86 of the medicine roll case 84 is provided on the side opposite to the fertilizer roll case 16 side, the remaining medicine is recovered.
