Description

[Detailed description of the invention] The present invention has one running wheel and at least one ground contact body arranged in the front-rear direction of the aircraft when viewed from the side, and the driver's seat can be repositioned and fixed in the front-rear direction. This article relates to a riding rice transplanter.

This type of riding rice transplanter has a simpler structure, is cheaper, and has a simpler structure than a general-purpose riding rice transplanter that uses a tractor as the main machine.
Although it is advantageous in that it can be constructed lightweight, when traveling on the road, the front and back posture of the aircraft is not stable at all, and therefore, it has to be transported by being loaded onto a transport vehicle such as a light truck.

In addition, since the driver's seat is configured to be repositionable and fixed in the longitudinal direction, even if the longitudinal balance of the aircraft changes due to factors such as changes in the amount of remaining seedlings during planting, the driver's seat can be repositioned in the longitudinal direction. By doing so, the longitudinal balance of the aircraft can always be properly maintained. However, when the driver's seat is moved forward or backward to correct the aircraft longitudinal balance, the distance between the driver's seat and the control panel This causes the inconvenience that the steering position changes as the steering wheel becomes pinched or widened, making it difficult to control the vehicle.

In view of these circumstances, the present invention not only makes it possible to maintain a constant and comfortable operating posture even when the driver's seat is moved back and forth in order to correct the front-to-back balance of the aircraft, but also makes it possible to maintain a stable and comfortable operating posture. The space between the driver's seat and the control operation section can be freely adjusted according to the physique of the driver. The purpose is to make the vehicle self-propelled without using a transport vehicle when traveling on the road by utilizing a structure that can be adjusted by the vehicle.
In the officially registered control unit, the control unit in front of the driver's seat is configured to be able to change its position back and forth and maintain its position by swinging around its base end, and the control box of the control unit is configured to It is characterized by a structure in which the bundle rod can be changed and fixed in the forward and backward directions.

As a result, when the longitudinal balance of the aircraft changes due to factors such as changes in the amount of seedlings remaining during planting, even if the driver's seat is repositioned in the longitudinal direction, the control panel will also be able to swing back and forth accordingly. By moving the steering wheel, the distance between the steering operation section and the driver's seat can be maintained in a state that is most convenient for steering.

Moreover, since the control unit can be independently swung back and forth, the configuration for correcting the longitudinal balance of the aircraft to a stable state and easily maintaining the control posture at that time can be adjusted between the driver's seat and the control unit. It has now become possible to effectively utilize the structure for freely adjusting the distance between the control section and the operating section according to the physique of the driver.

By changing the direction of the steering wheel forward with respect to the control box of the control unit, when driving on the road, the driver can get off the road and hold the steering wheel while driving. Utilizing a structure that adjusts the relative distance between the driver's seat and the control unit according to the situation, the rice transplanter can be moved by itself using the driving force of the rice transplanter, without the need for a transport vehicle when traveling on the road. I was able to do it.

Moreover, since the handle is not a rotating handle but a handle rod, the handle does not wobble relative to the control box, and the vehicle can be driven on the road with stable operation.

Embodiments of the present invention will be described below based on the drawings.

The drawing shows a riding-type rice transplanter with four rows of planting, in which support cases 4, 4 for running wheels 3, 3 are arranged side by side at appropriate intervals in the left and right directions with respect to the direction of movement of the machine, on a mission case 2 directly connected to an engine 1. At the end of the pipe-shaped frame 5 extending rearward from the transmission case 2, there is a seedling stand tilted forward from the lower rear to the upper front. 6A, a planting device 6 is connected to the planting device 6, which consists of a planting claw 6B and a planting mission case 6C, which has a driving mechanism for these internally.

Further, at the front and rear positions between the running wheels 3, 3, and at the lower side of the engine 1, transmission case 2, and planting device 6, a width approximately equal to the opposing interval between the inner surfaces of the wheel support cases 4, 4 is provided. One float 7 and a pair of ground floats on the left and right that serve as a surface leveling function for planting seedlings? ', 7', the front float 7 is in a fixed position relative to the fuselage, and the rear float)? '.

7' are respectively disposed so as to be able to swing up and down with respect to the machine, and a steering clutch 9A is disposed on the control section frame 8 provided over the engine 1 and the transmission case 2.
, 9A is attached to the lower end of the support arms 9D, 9D extending downward from the control box 9C of the control operation section 9 having a clutch etc., and a bolt 10 inserted between them. and are pivotally connected via a nut 11 so as to be able to swing back and forth.

Between the lower ends of the support arms 9D and 90 of the control unit 9 and the control unit frame 8, there is a friction plate 12A of a friction holding mechanism 12 that holds the control unit 9 and the bolt 10 in position at an arbitrary location around the axes. , 12A, and the handle 9B is configured to be swingable and fixed around a horizontal axis parallel to the axis of the bolt 10.
It is configured so that its position can be changed back and forth and maintained by swinging around the 10-axis axis of the bolt, and it is also configured so that it can be switched to a walking operation position by tilting the aircraft forward.

Further, a frame 14 for mounting and supporting the driver's seat 13 so as to be movable only in the longitudinal direction is integrally connected to the control section frame 8, and within this driver's seat longitudinal movement guide frame 14, the driver's seat 1

is interlocked and connected to the rear float 7' which swings up and down in accordance with changes in ground pressure caused by fluctuations in the front-to-back balance of the aircraft, so that the expansion and contraction of the hydraulic cylinder 15 based on the change in ground pressure allows By moving the driver's seat 13 back and forth, the driver's seat 13 and the driver are used as balance weights to create a rear float? ',? 'The ground pressure is maintained almost constant.

Note that the valve 16 is configured so that it can also be switched by manual operation.
