Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a rice transplanter equipped with hydraulic cylinders for raising and lowering planting and for controlling rolling. do.

0002

[Conventional technology]

Conventionally, hydraulic cylinders were installed at approximately the same height on the rear side of the engine; The wheels are connected to the left and right swing cases, and the running wheels installed on the swing cases are connected to the hydraulic system. There was a technique to raise and lower it using Linda.

0003

[Problem that the idea aims to solve]

In the conventional technology, the hydraulic cylinder cannot be easily supported at a low position, and the center of gravity of the machine is high. This makes the aircraft support unstable, and the left and right running wheels or the upper bonnet Functionally, it may be necessary to remove parts such as parts for maintenance of the hydraulic cylinder. There were problems with handling and handling.

The swing plate protrudes from the left and right sides of the base frame, and running wheels are provided. A swing arm protrudes from the base of the swing case, and the swing plate is connected via a rod. Planting that connects the root to the swing arm and the swing plate The lifting hydraulic cylinder is installed inside the base frame and follows the slope of the base frame. The hydraulic cylinder for raising and lowering the planting is arranged as shown above, and the lorry tilts the planting machine from side to side. a hydraulic cylinder for controlling the planting, the hydraulic cylinder for raising and lowering the planting, and a swing plate. and are installed on approximately the same plane, supporting the hydraulic cylinder at a lower position than before. This allows you to easily lower the center of gravity of the machine, stabilize the support of the machine, and prevent rolling during planting. It can easily prevent falls when driving in meandering and meandering areas and when going over ridges, improving driving performance and safety. The base frame and rods can easily improve the hydraulic series. The outside of the machine can be enclosed and protected, and maintenance of hydraulic cylinders etc. can be done from the front and sides of the machine. It has a safe structure and is easier to handle than before, and it also has a seedling stand at the rear of the aircraft. However, by increasing the weight on the engine side using a hydraulic cylinder, etc. The front and back balance of the aircraft can be easily set using the conventional weights used for balance. It can be easily reduced in weight or omitted, and furthermore, each hydraulic cylinder and swing plate can be The swing plate can be used as a swing case with a flat and compact layout. They can be connected with a simple structure via a swing arm.

To prevent damage etc., transparent material is used in areas where timing adjustment is required, such as when horizontally feeding the planting area. Designed to improve work efficiency by using a lid that eliminates the need to remove it. has been completed.

[0013] This embodiment is configured as described above, and the seedling platform (8) can be moved back and forth from side to side or the tiller can be When the rice transplanter tilts to the left or right due to unevenness, etc. and performs rolling operation, the rice transplanter will descend The ground reaction force of the rear float (19) or (20) on that side becomes large, causing the rear float (19) or (20) on that side to Raise the front part of the seat (19) or (20) and switch the hydraulic switching valve (37) appropriately. to operate the rolling control hydraulic cylinder (35), and move the running wheel (1) on the downward slope side. 4) is forcibly lowered to support the rice transplanting machine approximately horizontally. At this time, each float (1 9) (20) is also supported substantially horizontally.

[0014] For example, if the rice transplanter leans to the right during rice transplanting, the right rear float (2 0) The rise of the front part is detected by the sensor arm (23), and this arm (23) The switching valve (37) is switched by the detection operation, and the rolling control hydraulic cylinder (3 5) Move the piston rod (36) in and out to swing around the pivot (31). Swing the right side of the plate (32) in a direction that pushes it forward, and then (34) and rotate the right swing case (15) around this pivot point. Rotate in the clockwise direction to make the right running wheel (14) protrude below the machine, and move it to the right side of the rice transplanting machine. , and support the rice transplanting machine approximately horizontally.

(40) is adjusted as appropriate by selecting the switching valve adjustment hole (38), and Adjust the switching amount of the hydraulic switching valve (37) to be large or small relative to the rotation amount of the sensor arm (23). It can be adjusted accordingly. This adjustment allows the hydraulic cylinder ( 35) can be made sensitive or insensitive, allowing for accurate rolling control of the aircraft. Ru.

[0016] Furthermore, when changing the direction of the rice transplanter at the edge of a ridge or driving on the road, oil for lifting and lowering the rice planter is used. The piston rod (29) of the pressure cylinder (28) is made to protrude and the swing plate ( 32) forward and the left and right swing rods (34) (34) Rotate the swing case (15) (15) clockwise around this pivot point to the left. Protrude the right running wheels (14) (14) downwards to raise the entire rice transplanter. .

[0017] In addition, a pitching sensor is interlocked and connected to the planting lifting hydraulic cylinder (28). The pitching control of the aircraft can also be changed to rolling control by being equipped with a hydraulic switching valve. We can do it together.
