Description

  The present invention relates to a technique of a medicine spreader that is attached to the rear part of a traveling vehicle and spreads medicines in the left-right direction of the machine body.

  Conventionally, boxing agents that spray osmotic transfer granules onto seedling boxes just before rice planting and extinguish pests that occur soon after transplanting are known. It was a very cumbersome task to spray on. Therefore, Patent Document 1 discloses a working machine in which a drug spreader is mounted above a seedling stage of a rice transplanter, a drug is spread on a seedling mat by the drug spreader, and medicine can be applied simultaneously with rice planting. It has become. The medicine spreader described in Patent Document 1 is configured such that one medicine spreader can be applied to two seedling mats. In addition, the drug sprayer is characterized in that the drug is sprayed directly on the seedling mat before planting.

  On the other hand, Patent Document 2 discloses a chemical spreader that can spray a range corresponding to the number of planting lines of a rice transplanter with a single chemical spreader. The drug spreader is provided with a diffusion part below the drug spreader, and can spread the drug to the width of the number of planting lines of the rice transplanter. The drug spreader is characterized in that the drug is sprayed directly on the soil.

Here, a lateral groove roll type is publicly known in Patent Document 1 for a feeding part that feeds a drug on a grain from a drug hopper of a drug spreader. The horizontal groove roll type is a structure in which several grooves are provided in the column direction of the roll, and the rolls are rotated to feed out seeds contained in the grooves. Here, the adjustment of the amount of sprayed medicine is performed by adjusting the width of the groove and the rotation speed of the roll. In other words, there is a highly adaptable feature that can cope with changes in the size and spread of the medicine. Further, since the transverse groove roll type has a simple shape, the feeding portion to be stored can be reduced in volume and weight.

  On the other hand, the technique of Patent Document 2 includes a so-called eye-plate-type feeding device in which the feeding device has a feeding hole around a circular feeding plate. This medicine is fed out, and the spraying blade disposed below is rotated so that the falling medicine is sprayed to both sides along the spray cover. However, since this feeding device arranges the feeding plates in the horizontal direction and is arranged side by side, the feeding case becomes large and a large space is required. Furthermore, since driving mechanisms were arranged on both the left and right sides to drive the two left and right feeding plates, the number of parts increased, the weight increased, and the rear side became heavier, so the balance was poor. is there. In addition, since there are drive mechanisms on the left and right, it is necessary to adjust the left and right in order to adjust the spraying amount, and the spraying amount may differ slightly. Accordingly, the problem to be solved by the present invention is to provide a single medicine hopper with two lateral groove roll-type feeding portions to achieve compactness, so that two feeding rolls can be driven by one driving mechanism, The number of points is also reduced so that it can be sprayed separately on the left and right.
