Description

[Detailed Description of the Invention] The present invention relates to a seat support structure for a riding rice transplanter.

As a means of increasing the efficiency of the work of a riding rice transplanter, it is desirable to make the rice transplanter light and stable, and to reduce the headland during rice transplanting work.
To achieve this, it is necessary to reduce the rotation radius of the rice transplanter, which requires shortening the overall length of the rice transplanter. One way to do this is to omit the frame between the rear wheels of the passenger vehicle, install an elevating link mechanism between them to support the rice transplanter, and position a transmission shaft, etc. that transmits power from the passenger vehicle to the rice transplanter. A rice transplanter with the following configuration has been proposed. It is appropriate that the hydraulic cylinder for operating the elevating link mechanism and the transmission shaft be located approximately at the center between the rear wheels, and a space is formed above these hydraulic cylinders and the transmission shaft.

By the way, it is desirable that the operator's seat in a passenger car is located above the rear wheels, but as mentioned above, the hydraulic cylinder and transmission shaft pass through the center between the rear wheels, and has no frame. Therefore, it is difficult to construct a structure that supports the seat.

The present invention aims to provide a seat support structure that solves the above-mentioned problems.The present invention aims to provide a seat support structure that solves the above-mentioned problems. Attachment, both transmission cases are extended diagonally downward to the rear, and the rear wheels are supported at their rear ends, and a connecting member is used to connect the two transmission cases, and a supporting member is erected on the connecting member to support the rear wheels. By providing a seat at the upper end, the weight of the operator is directly applied to the rear wheels, making the aircraft more stable and lighter.

Hereinafter, the explanation will be given with reference to the drawings. In the drawings, reference numeral 1 denotes a passenger vehicle body, and 2 a rice transplanting work machine, which is supported by the vehicle body 1 by an elevating link mechanism 3. The passenger vehicle body 1 includes an engine 5 supported by a frame 4, an intermediate shaft 6, a transmission case 7, etc., and the front end of a transmission case 8 is fixed to both left and right sides of the transmission case 7. The rear wheels 10 extend diagonally downward and the rear wheels 10, 10 are pivotally supported at the rear ends of the wheels.
The rear wheels 10, 10 are driven by a transmission mechanism that extends from the inside of the transmission case 7 to the rear wheels 10, 10 through the inside of the transmission case 8. With such a configuration, a frame between the rear wheels 10 and a shaft between the rear wheels are omitted. A hydraulic cylinder 11 that operates the elevating link mechanism 3 between the rear wheels 10 and 10 is located approximately in the center, and its front end is pivotally supported by a pin 12 on the outside of the transmission case 7.

A connecting member 13 is fixed and connected between both transmission cases 8, 8, and a pair of arms 14 are attached to the member 13.
is supported. A connecting rod 15 is fixed to the upper end of the arm 14, and an upper link 16 is attached to it.A pair of left and right lower links 17 is attached at an intermediate position between both arms 14, and a pair of lower links 17 are attached to the rear of both upper and lower links 16, 17 The ends are connected by a link 18 to form the elevating link mechanism 3. Said hydraulic cylinder 1
The tip of the piston rod 20 of 1 is the upper link 16
The link mechanism is swung by the operation of the piston rod 20, and the rice transplanting machine 2 is moved up and down. Furthermore, a transmission shaft 21 that transmits power from the passenger vehicle body 1 side to the rice transplanting work machine 2 is also disposed passing through a position close to the center line of the vehicle body.

A support member 22 is fixed to the connecting member 13 on one side away from the center position in the left-right direction of the aircraft body, and a lower end portion of a seat support pipe 23 is fixed to this. A seat 24 is fixed to the upper end of the support pipe 23 so that its center is located above the center line of the vehicle body and has a space below.
In the space below the seat 24, a battery support stand 2 with an open bottom on the support pipe 23 is installed.
5 is fixed, and a battery 26 is loaded on top of it.

As is clear from the above, in the present invention, the hydraulic cylinder 11 and the transmission shaft 21 etc. that actuate the elevating link mechanism 3 pass near the center between the rear wheels 10, 10, but the seat 24 is placed above the connecting member 13. Since it is supported by an erected support pipe 23 and positioned above the hydraulic cylinder 11, transmission shaft 21, etc.,
The weight of the operator is directly applied to the rear wheels, and despite its simple structure, it is strong enough, and each part can be placed in the most preferable position mechanically without interfering with the arrangement of each mechanism. . Furthermore, the weight of the machine is light, and the overall length can be shortened to make the whole machine smaller.
