Description

TECHNICAL FIELD The present invention relates to a passenger rice transplanter equipped with a rice transplanter behind a passenger towing vehicle.

[Conventional technology and its problems]

Conventionally, in this type of rice transplanter, a rising portion that rises to a position higher than the step surface is formed at the rear portion of the vehicle body cover that covers the upper portion of the passenger towing vehicle, and the control seat is provided above the rising portion. The arrangement was known. However, in this conventional device, since the rising part is located right beside the front end of the control seat, when the operator turns the spare seedling backward and supplies it to the seedling tank of the rice transplanter, he must twist the body greatly to perform the supply work. Therefore, the seedling supply work was very difficult.

[Means for Solving the Problems]

In order to solve the above problems, the present invention is equipped with a rice planting device 20 in the rear of the passenger towing vehicle 1 so that the upper end of the seedling tank 23 on the seedling supply port side is located near the rear of the control seat 9. In the riding rice transplanter, a rising portion 7b is formed at a rear portion of a vehicle body cover 7 that covers an upper portion of the passenger towing vehicle 1 so as to be higher than a step surface 7a, and the steering is provided above the rising portion 7b. While the seat 9 is provided, the rising portions 7b on both the left and right sides of the control seat 9 are formed so as to be shifted rearward by a larger amount than the front end of the control seat 9 to form a recess 19 into which the operator's foot can enter. It is a characteristic rice transplanter.

[Advantageous effects of the invention]

According to the present invention, when supplementary seedlings are supplied to the seedling tank 23 of the rice planting device 20, the operator can easily supply them by putting his / her feet into the recessed portion 19, and as in the conventional riding rice transplanter, only the upper half of the body is screwed backward. The seedlings can be replenished in a comfortable posture without the need to get them, and rice planting work can be performed efficiently.

It is supported by a pole 12 that stands upright.

Then, the rising portions 7b and 7 on both the left and right sides of the control seat 9
The position b is displaced rearward by a larger amount than the front end of the control seat 9, and a recess 19 into which the foot of the operator can be inserted is formed.

Reference numeral 13 denotes a steering guide panel which is fixed to the connecting frame 10 on both left and right sides of the steering seat 9. The front side of the panel 13 is located considerably rearward of the front end of the steering seat 9, and the panel 13 Guide grooves 14a.1 for restricting the guide of the planted clutch lever, 14, the hydraulic operation lever 15, the hydraulic adjusting lever 16 for adjusting hydraulic operation, and the like.
5a and 16a are drilled.

Reference numeral 17 is a spare seedling placing table, which is a pipe with a U-shaped side view and a ⊂-shaped side view so that the seedlings raised in the seedling box can be placed and stored as they are, and the seedling box is received on the bottom side of this pipe. The auxiliary seedling placing table 17 is provided on the outside of the operation guide panel 13 and is provided by the wire rod to be stretched.
It is attached to a support frame 18 which is arranged so as to project more largely than the front end of the connecting frame 10 and projects outward from the connecting frame 10.

Therefore, the operation guide panel 13 is provided between the control seat 9 and the spare seedling placing table 17, and the above-mentioned recess 19 is provided in the front part of the operation guide panel 13.

Reference numeral 20 denotes a rice transplanter, which supports a seedling tank 23 on the upper part of the main transmission case 21 so that the front side is inclined so as to reciprocate left and right, the base is fixed to the main transmission case 21, and the tip is rearward. A pair of left and right auxiliary transmission cases 22 that extend
22 is mounted with a seedling planting rod 24 by a crank and a swing arm, and a main float 25 and sub floats 26, 26 are freely movable up and down at the lower side of the main transmission case 21 and the sub transmission case 22. It is provided so that.

27 is a lifting link, which is an upper link rod 27a and a lower link rod 2
The base of 7b is pivotally attached to the pole 12 of the towing vehicle 1, and the rear ends of both link rods 27a and 27b are pivotally connected by a connecting frame 28, and the main transmission case 21 of the rice transplanter 20 can be freely rolled on this connecting frame 28. Is attached to.

At this time, the front end side of the seedling tank 23 is arranged near the rear of the control seat.

Reference numeral 29 is a hydraulic cylinder device. The base of the cylinder 29a is pivotally attached to the mission case 2 at the tip end of the piston 29b and the arm 30 attached to the upper link rod 27a. Is provided.

Reference numeral 31 denotes an oil pressure switching valve, which is interposed between the main transmission case 21 and the main float 25, and when the main float 25 moves upward by a certain amount or more, the piston 29b is switched to the projecting side, and when it moves downward, it retracts. It is provided so that it can be switched to the side.

Further, the hydraulic pressure switching valve 31 corresponds to the hydraulic pressure control lever 1
It is provided so as to be interlocked so that it can be arbitrarily switched by 5, and the switching operation resistance thereof can be adjusted by the hydraulic pressure adjusting lever 16.

Reference numeral 32 denotes a transmission shaft for transmitting from the pulling unit 1 side to the rice transplanter 20 side.

In the configuration of the above example, after the seedlings are first placed and placed in each of the preliminary seedling placement table 17 and the seedling tank 23, when the respective parts are transmitted by the engine, the passenger towing vehicle 1 causes the rice planting device 20 to move the main float 25, The sub-floats 26, 26 are towed in a state where they are in contact with the paddy field soil, and the seedling planting rods 24 are divided and planted one by one from the seedling tank 23 which is reciprocated left and right.

Although the seedling planting work is proceeded in this way, when the seedlings in the seedling tank 23 are exhausted and the seedlings need to be replenished, the operator once disengages the main clutch to stop the rotation of each part and stop the aircraft. The seedlings in the spare seedling placing table 17 are supplied to the seedling tank 23. At this time, since the feet of the operator enter the recesses 19 formed on the left and right sides of the control seat 9, the operator can put the whole body in a substantially sideways posture, and the preliminary seedling mounting can be performed without a large twist. Seedlings are taken out from the stand 17 and seedling tank 2
You can supply seedlings to 3. Further, since various operation levers are provided on the side of the control seat 9, the operation is easy as in the conventional case. .
