多条田植機に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a so-called multi-row rice transplanter that is equipped with a large number of planting claws in parallel and plants seedlings along multiple rows. At regular intervals,
This is a multi-vehicle multi-purpose vehicle in which a rice seedling planting device, which connects a plurality of transmission cases equipped with planting claws, a float, and a seedling mounting table, is attached so that it can be raised and lowered, and a worker performs rice planting work while sitting on a traveling vehicle. Regarding row rice transplanter.

らず、作業能率を大きく低下させるものであつた。Conventionally, in multi-row rice transplanters, in order to plant in fewer rows than the total number of rows to be planted, for example near the edge of a ridge, seedlings corresponding to the rows where no planting will be done are removed from the seedling stand. However, this method of planting a small number of rows In this case, and when returning to normal planting after that, the work must be interrupted each time to move and restore the seedlings, which greatly reduces work efficiency.

題点がある。That is, each time the worker gets off the moving vehicle into the field, walks through the mud to the seedling planting equipment, performs the above-mentioned tasks, and then walks through the mud to return to the vehicle and sit on the vehicle. This is due to the fact that this type of riding multi-row rice transplanter not only reduces work efficiency, but also makes the rice field rough, getting on and off the vehicle, and walking around the field is troublesome. There is.

して連結した点にある。The present invention provides a riding-type rice transplanter as described above, in which the clutch mechanisms provided in each of the plurality of transmission cases of the seedling planting device attached to the traveling vehicle body can be operated from the traveling vehicle body while the rice transplanter is on the vehicle. The aim is to make it possible to easily and quickly change the number of planting rows between planting and small number planting without interrupting work, and describes the specific technical measures adopted to solve this problem. In each transmission case, a clutch mechanism for stopping the driving of the planting claw is provided, and an operating part for separately operating each clutch mechanism is provided within the range that can be operated from the seat, The operating section and each clutch mechanism are connected via wires.

る。According to the characteristic structure described above, there is no need for an operator to get off the vehicle and manipulate the seedlings on the seedling table in order to switch from full-row planting to small-row planting, or vice versa. Since switching of each clutch mechanism can be performed from the top of the vehicle while sitting in the seat using the operating unit near the seat, the desired planting pattern can be easily and quickly obtained when turning headlands, etc., without interrupting work. This has the effect of improving work efficiency. Furthermore, in the present invention, since the operating section and the clutch mechanism are connected by a wire, dimensional errors between the two can be easily absorbed by bending the wire, and the two can be interlocked and connected with an extremely simple structure. Moreover, when the seedling planting device is removed from the traveling vehicle body, the attachment/detachment operation of the connecting end of the wire is simple, so that the attachment/detachment operation can be performed very easily and quickly. Next, embodiments of the present invention will be described in detail based on illustrative drawings.

植付爪６，６の破損を回避できるように構成してある。The clutch mechanism 11 has a power transmission member 15 spline-fitted to the bevel shaft 14 so as to be slidably movable in the axial direction, and a bearing member that is loosely fitted and supported to the bevel shaft 14 so as to be slidable in the axial direction. 16 is connected to a rod 17 slidably mounted on the transmission case 9, and a compression spring 18 is stretched between the transmission member 15 and the bearing member 16, so that the power transmission member 15 is normally connected to the transmission case 9. A rotary member 19 connected to the shaft end of the shaft 10 interlocks to drive the planting claws 6, 6,
When the planting claws 6, 6 come into contact with the hard ground and the driving load becomes large, the power transmission member 15 moves against the biasing force of the spring 18 and disconnects from the rotating member 19. ,
It is constructed so that damage to the planting nails 6, 6 can be avoided.

。The gear ratios of the bevel mechanism 12 are equal, and the bevel shaft 12
The drive shaft 13 rotates once per rotation, and the planting claws 6, 6 are configured to perform one planting operation, and are interposed between the power transmission member 15 and the rotating member 19. By arranging the engaging cam member 20 asymmetrically around the rotation axis and making the relative phase angle of both shafts 10 and 14 constant during transmission,
The eight planting claws 6 are constructed so that the entire planting operation is always performed in the same posture. The rods 17, 17 are pivotally connected to swing levers 21, 21 on the outside of the transmission case 9, and their swing operation moves the bearing member 16 in the axial direction of the bevel shaft 14 and rotates it. The power transmission member 15 is separated from the member 19 to cut off the power transmission to the planting claws 6, 6, and when planting a small number of rows, etc., two planting claws 6, 6 can be arbitrarily connected to each transmission case 9. It is configured so that it can be stopped.
