[Detailed description of the invention] The present invention is a rice transplanter in which a rice transplanting body such as an engine and a seedling stand is supported in a vertically movable manner by the hydraulic pressure of a cylinder that operates as appropriate based on changes in the ground pressure of a float on a rice field. Regarding.

Conventionally, technology for forcibly lowering the height of the wheels in conjunction with the cutting operation of a side clutch installed in the power transmission system for a pair of left and right rice paddy wheels that run while touching the tiller (for example, in practical applications) Publication No. 139629 (Sho 50-139629) was published.

As a result, when the side clutch is repeatedly engaged and disengaged, for example, when turning at the edge of a ridge during rice planting work or when driving on the road, there are problems such as the hydraulic cylinder operating in the direction of raising the aircraft each time. Hydraulic circuits such as cylinders are easily damaged, the durability of the hydraulic system is significantly reduced and oil leaks occur, and there are safety issues such as damage to the aircraft lifting mechanism connected to the cylinders. In addition, in order to solve this problem and use it safely, a mechanism to connect and disconnect the side clutch disengagement operation and the aircraft lifting operation is required, making it difficult to simplify the structure and reduce costs. Not only this, but also structural and operational problems such as complicated handling operations occurred.

Therefore, the present invention uses a side clutch lever provided on the steering handle that can be operated in multiple stages, so that after the side clutch is disconnected, the rice transplanting machine is raised only when the lever is further disconnected. The side clutch lever is provided with a regulating member that restricts the lever operation of the side clutch lever to only the on/off operation of the side clutch.

As a result, by separately operating the side clutch engagement/disengagement operation and the aircraft lifting operation, it is possible to repeatedly engage/disengage the side clutch while the aircraft lifting mechanism such as the cylinder is stopped and held. This eliminates the conventional problems such as the hydraulic cylinder operating in the direction of raising the aircraft every time the side clutch is engaged or disengaged, and prevents damage to the cylinder's hydraulic circuit and oil leakage due to reduced durability of the hydraulic system. It prevents damage to the machine lifting mechanism linked to the cylinder, and enables safe turning in narrow spaces such as ridges during rice planting work, as well as turning while driving on the road, with extremely simple driving operations. When there is no need to raise the aircraft any further after it has already been raised while driving, or when there is no need to raise the aircraft using the side clutch lever during rice planting work, operate the lever to raise the aircraft. This can be easily prevented with an extremely simple regulating member, which eliminates erroneous operation of the side clutch lever due to swinging of the steering wheel while driving, prevents the aircraft from rising unnecessarily, and prevents the aircraft from rising. In order to prevent damage to the aircraft, the aircraft is raised only when it is necessary to raise the aircraft using the side clutch lever, and the side clutch levers are always engaged and disconnected independently and the aircraft is raised, making it extremely easy and safe. It is made so that it can be handled.

As shown in the embodiments above, the present invention has a cylinder 34.
A side clutch lever 18 that can be operated in multiple stages is connected to a lifting operation arm 49 that raises the lever, and after operating the lever 18 to disconnect the side clutch 36, the lever 18 is further operated in the direction of disengaging the side clutch 36. By raising the aircraft, the side clutch 36 can be engaged and disconnected and the aircraft lifting operation can be operated separately. Therefore, the side clutch 36 can be engaged while the aircraft lifting mechanism such as the cylinder 34 is stopped and held. The disengagement operation can be repeated repeatedly, eliminating problems such as the hydraulic cylinder operating in the direction of raising the aircraft every time the side clutch is engaged and disengaged, which prevents damage to the hydraulic circuit of the cylinder 34 and the hydraulic system. This prevents oil leakage due to decreased durability of the cylinder 34 and damage to the machine lifting mechanism linked to the cylinder 34, making it extremely easy to turn in narrow spaces such as the edges of rice fields and while driving on the road. This can be done safely with proper driving operation, and the side clutch lever 18 can be moved to the side clutch 3.
By providing a lever regulating pin 54 on the lever 18, which is a regulating member that restricts only the connecting and disconnecting operations of 6, when there is no need to raise the aircraft any further when the aircraft has already been raised, such as when traveling on the road,
Alternatively, when there is no need to raise the machine using the side clutch lever 18 during rice transplanting work, raising the machine using the lever 18 can be facilitated by a very simple regulating operation that changes the regulating pin 54 from the lying state to the upright state. Therefore, it is possible to prevent malfunction of the side clutch lever 18 due to the swinging of the steering handle 7 while the vehicle is running, prevent unnecessary lifting of the aircraft, and prevent damage to the aircraft due to the lifting of the aircraft. The aircraft can be raised only when it is necessary to use the side clutch lever 18 to raise the aircraft, and the side clutch lever 18 can always be engaged and disconnected independently and the aircraft can be raised, making it extremely simple. Moreover, it has remarkable effects such as being able to be handled safely.
