Japanese Unexamined Patent Publication No. 2006-34175 (paragraphs 0027 and 0028, see FIGS. 1, 5, and 6)

The above structure is thought to be useful in that it is possible to reduce the amount of fertilizer to be applied because the fertilizer can be sprayed in a dotted state on the field where the seedlings are planted by the rice-transplanting device.

However, in this structure, fertilizer is supplied once in association with the transplantation of one seedling, but regarding the relative positional relationship between the location where the seedling is transplanted and the location where the fertilizer is applied, It is not specially considered.

For this reason, by spotting, fertilizer can be applied intensively compared to the case of sowing, but it is said that all of the fertilizer applied intensively acts more effectively on individual seedlings than fertilizer when sowing. There are cases where it cannot be done, and in the end, there are cases where the effect leading to the reduction of fertilizer cannot be effectively exhibited.

The above configuration is thought to be useful in that the amount of fertilizer to be applied can be reduced because the fertilizer can be applied in a dotted state to the field in which the rice is planted by the rice-transplanting device.

However, in this structure, no special consideration is given to the relative positional relationship between the place where the seedlings are planted and the place where the fertilizer is applied, so even if an appropriate amount of fertilizer is supplied to the entire field, the amount of fertilizer supplied to a specific transplanted plant. This variation occurs for each seedling stock, and in supplying an appropriate amount of fertilizer to each seedling stock, no arrangement has been made so that the total amount of the fertilizer is also reduced.

The present invention is designed so that the supply position of the fertilizer or drug to the package is appropriate for the supply position of each seedling or rice seed to the package, and the supply amount of the fertilizer or drug to the package for the seedling or rice seed at each supply position It's what you want to do to save money.

The drive shaft 25a of the rice seed feeding unit 25 is pivotally supported so as to be able to integrally rotate. This input gear 81 is comprised so that the driving force of the 1st relay shaft 52 can be intermittent via the 1st water tank clutch 53.

That is, when the first small number clutch 53 spline-fitted to the first relay shaft 52 is operated to the input side and engages with the side surface of the transmission gear 52a, it is always engaged at the outer peripheral side of the transmission gear 52a. The driving force is transmitted to the input gear 81 that does. When the first water tank clutch 53 is operated to the disconnection side, the transmission gear 52a is in an idle state, and power transmission to the input gear 81 side is disconnected.

Among the input gears 81, the odd-numbered input gears 81 from the left shown in FIG. 9 are, as shown in FIG. 81A) and an annular rotary plate 81B detachably installed on the side surface of the input rotary body 81A via a fixing bolt 81C, and a plurality of A driving pin 82 is protrudingly installed. The collar 82a is loosely fitted to the drive pin 82, and it is configured to avoid wear of the drive pin 82 due to contact with the link member 83 of the intermittent linkage mechanism 80.

Among the input gears 81, the even-numbered input gears 81 from the left shown in FIG. 9 do not have the annular rotating plate 81B or the driving pin 82, but have a gear portion on the outer circumferential side. It is constituted only by the input rotating body 81A.

The input gear 81 composed only of this input rotating body 81A is a linkage mechanism composed of the relay gear 66, the first conversion unit 60, and the second conversion unit 61 shown in FIGS. 9 to 11. Through (50), it is comprised so that driving force may be transmitted to two medicine|medical agent dispensing parts 34 in adjacent positions.

Therefore, as shown in FIG. 12, the rear end 83A of the link member 83 is accompanied by clockwise rotation of the input gear 81, as shown by a solid line, one driving pin 82. From the state of contacting the collar 82a, it is pushed up as shown by a phantom line, and with this, the front end 83B of the link member 83 pulls the linkage rod 85, and the arm member 72a rotate clockwise. As a result, the valve body 73 swings toward the open side, and the medicine is dropped and supplied.

When the rear end 83A of the pushed up link member 83 is removed from the collar 82a of the drive pin 82, the biasing action of the biasing spring 86 causes the rear end of the link member 83 to move. As shown by the solid line again, the end portion 83A comes into contact with the collar 82a of the next driving pin 82. In this state, the front end 83B of the link member 83 releases the pulling operation of the linkage rod 85 and is pushed back, and the arm member 72a swings counterclockwise by the action of the return spring 77. It returns, and at the same time, the valve element 73 also returns to the closed position.
