Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a clutch control mechanism of a riding micro-tillage machine. Background Art

[0002] For a ride-on micro-tillage tractor, the operator can sit in the driving seat and perform tillage or driving. Compared with a walk-behind micro-tillage tractor, the labor intensity is lower, but there are still some shortcomings: when the road slope is large, or when used in hilly and mountainous areas, the road conditions are bumpy, and the driver sitting in the driving seat to control the micro-tillage tractor will face the risk of overturning. In the above situation, if the driver leaves the driving seat, he cannot continue to control the micro-tillage tractor. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a clutch control mechanism for a riding micro-tiller. Through the above structure, by setting a first control unit and a second control unit, after leaving the driving seat, the micro-tiller can still be controlled to move forward or stop at the tail of the micro-tiller, thereby ensuring driving safety on roads with large slopes or in hilly and mountainous areas.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A clutch control mechanism for a riding micro-tillage machine comprises a first control unit and a second control unit, wherein the first control unit comprises a pedal rod rotatably mounted on the micro-tillage machine, and the pedal rod can drive a fork shaft of a clutch to rotate;

[0006] The second control part comprises a traction cable, one end of which is connected to the handle assembly, and the other end of which is connected to the pedal rod. The traction cable can drive the pedal rod to drive the shift fork shaft to rotate.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] When the operator sits on the micro-tiller to drive, he can control the rotation of the fork shaft by the pedal rod, thereby controlling the clutch to close. When the road slope is large, or when it is used in hilly or mountainous areas, the operator can stand at the rear of the micro-tiller and pull the traction cable, which pulls the pedal rod to control the clutch to close. Through the above structure, by setting the first control unit and the second control unit, the micro-tiller can still be controlled to move forward or stop after leaving the driving position, ensuring driving safety on roads with large slopes or in hilly and mountainous areas.

[0009] As a preferred embodiment of the present utility model, the outer end of the shift fork shaft is fixedly connected with a first rotating plate, and a traction spring is installed between the first rotating plate and the pedal rod.

[0010] Beneficial effect: when the pedal rod is pressed down, the middle part of the pedal rod drives the first rotating plate to move downward through the traction spring.

When the pedal rod is no longer pressed down, the elasticity of the reset spring makes the fork shaft reset, and the traction spring drives the pedal rod to reset.

[0013] As a preferred embodiment of the present utility model, the traction spring and the return spring are both hook springs.

[0014] Beneficial effect: The hooks at both ends of the hook spring can be inserted into the holes or stuck on the shaft, making disassembly and assembly more convenient.

After the second rotating plate 24 rotates, the return spring 26 is stretched. When the pedal rod 21 is no longer pressed down, the elasticity of the return spring 26 causes the fork shaft 1 to reset, and the traction spring 25 drives the pedal rod 21 to reset.

[0032] In this embodiment, the traction spring 25 and the return spring 26 are both hook springs, and the fixing part 22 is a fixing bolt. A threaded hole is opened on the micro-tiller, and the fixing bolt is installed on the threaded hole. Some studs are located outside the micro-tiller, and the hook spring is clamped on the studs.

[0038] Specific use (working) process:

[0039] When the operator is driving on the seat, he steps on the pedal rod 21, and the middle part of the pedal rod 21 drives the first rotating plate 23 to move downward through the traction spring 25, and the first rotating plate 23 drives the fork shaft 1 and the second rotating plate 24 to rotate. After the second rotating plate 24 rotates, the return spring 26 is stretched. When the pedal rod 21 is no longer pressed down, the elasticity of the return spring 26 makes the fork shaft 1 reset, and the traction spring 25 drives the pedal rod 21 to reset, thereby controlling the clutch to close;

[0040] When the operator operates at the rear of the micro-tiller, he holds the handle 34 tightly so that the handle 34 and the fixed plate 32 are closed. The fourth rotating plate 33 drives the connecting rod 35 to slide along the sliding groove 36, thereby pulling the traction cable 31. The traction cable 31 pulls the fork shaft 1 to rotate through the pedal rod 21 and stretches the reset spring 26. After releasing the handle 34, due to the elasticity of the reset spring 26, the traction cable 31 is pulled in the reverse direction to reset the handle 34. Therefore, the operator can also control the clutch to close at the rear of the micro-tiller.
