Description

Technical Field

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

[0002] A riding micro-tillage machine is an agricultural machine characterized in that the driver can sit on the machine to operate it. Compared with traditional handheld or walk-behind micro-tillage machines, it greatly reduces the operator's physical exertion and improves work efficiency and comfort. An existing riding micro-tillage machine includes a foot pedal arranged in front of the micro-tillage machine for the driver to control the engagement or disengagement of the clutch while riding, and also includes a clutch control mechanism arranged on the rear side of the seat. When facing some rugged and bumpy road conditions or specific scenarios, the driver can leave the driving seat and control the micro-tillage machine through the clutch control mechanism arranged at the rear of the micro-tillage machine, thereby avoiding the driver from falling over and getting injured.

[0003] However, the above-mentioned riding micro-tillage machine has disadvantages: the clutch control mechanism is installed on the seat, which is not only inconvenient for the driver to operate, but also causes a certain degree of damage to the seat after long-term operation, thereby reducing the service life of the seat. Utility Model Content

[0004] The technical problem to be solved by the utility model is that, in view of the above-mentioned defects, a rear control mechanism of a riding micro-tillage machine is provided, which is not only convenient for the driver to operate during field transportation, but also will not cause damage to the seat after long-term operation.

[0005] The utility model solves the technical problem by adopting the following technical solution: a rear control mechanism of a riding micro-tillage machine, comprising an operating component and an operating frame arranged at the rear of the micro-tillage machine body, wherein the operating component is arranged on the operating frame, and the operating component is used to control the engagement or disconnection of a clutch on the micro-tillage machine.

[0006] Compared with the prior art, the beneficial effect of the present solution is that an operating frame is provided at the rear of the micro-tiller body, and an operating component for controlling the engagement or disconnection of the clutch on the micro-tiller is arranged on the operating frame. Compared with directly setting the operating component on the seat, setting the operating component on the operating frame not only makes it easier to operate the operating component, but also avoids damage to the seat during operation, thereby extending the service life of the seat.

[0007] As a preferred embodiment of the present invention, the operating frame is arranged behind the seat.

[0008] The beneficial effect of this solution is as follows: when the driver needs to get down from the driving seat and stand to operate the micro-tiller to continue driving, the driver moves to the rear of the micro-tiller, holds the operating frame arranged behind the seat with his hands, and then controls the engagement or disconnection of the clutch through the operating component, so that the micro-tiller continues to drive. The operating frame is arranged behind the seat, and the structure is reasonable, which can not only ensure that the driver is always located behind the micro-tiller when driving the micro-tiller while standing, avoiding the micro-tiller from causing harm to the driver during driving, but also will not interfere with the driver's driving when sitting on the seat.

[0009] As a preferred embodiment of the utility model, the operating frame can be turned relative to the front gearbox arranged on the micro-tiller body.

[0010] The beneficial effects of this solution are as follows: since the operating frame can be steered relative to the front gearbox, when the driver stands behind the micro-tiller and controls the micro-tiller to drive, when the driver needs to steer the micro-tiller, the steering of the micro-tiller can be controlled by rotating the operating frame. The driving and steering of the micro-tiller can be controlled by the operating assembly and the operating frame, which is the same as the function of riding and driving the micro-tiller. Driving the micro-tiller from behind the micro-tiller does not affect the normal use of the micro-tiller.

[0011] As a preferred embodiment of the utility model, the operating frame and the seat are both arranged on a rear frame of the micro-tillage machine body, and the rear frame can be turned relative to a front gearbox arranged on the micro-tillage machine body.

[0012] The beneficial effects of this solution are as follows: the seat and the operating frame are both arranged on a rear frame body that can be steered relative to the front gearbox, the seat can be steered synchronously with the operating frame without interfering with the rotation of the operating frame, and the overall structure is more compact.

[0013] As a preferred embodiment of the present invention, the operating assembly is detachably connected to the operating frame.

[0014] The beneficial effect of this solution is that the operating component is detachably connected to the operating frame. When the operating component is damaged or the position of the operating component on the operating frame needs to be adjusted, the operating component can be removed from the operating frame for replacement or adjustment.

[0015] As a preferred embodiment of the utility model, the operating component is connected to a connecting component, the connecting component includes a cable and a driving part, both ends of the cable are respectively connected to the handle and the driving part, and the driving part is used to control the engagement or disconnection of the clutch.

[0016] The beneficial effects of this solution are as follows: the two ends of the cable are respectively connected to the handle and the drive unit. When the driver stands behind the seat and presses the handle, the cable moves accordingly and drives the drive unit to move, thereby controlling the engagement or disconnection of the clutch through the drive unit. The structure is reasonable, and the engagement or disconnection of the clutch can be remotely controlled through the cable and the drive unit, avoiding the driver still having to sit in the driving seat to operate the micro-tiller in the face of some dangerous scenarios, thereby avoiding the driver from falling over and getting injured from the micro-tiller.

[0017] As a preferred embodiment of the utility model, the driving part includes a fixed shaft arranged on one side of the micro-tillage machine body and a connecting rod that can swing with the fixed shaft as the rotation center, and one end of the connecting rod is connected to the cable.

[0018] The beneficial effect of this solution is that when the driver stands behind the seat to operate the tiller, he presses the handle to drive the cable to move. Since the cable is connected to one end of the connecting rod, the connecting rod will swing with the fixed axis as the rotation center as the cable moves, thereby controlling the engagement or disengagement of the clutch.

[0036] Specific operation process

[0037] When the driver needs to get down from the driving seat and stand to operate the micro-tillage machine to continue driving, the driver moves to the rear of the micro-tillage machine, holds the holding rod 501 on the operating frame 5 arranged behind the seat 3 with both hands, and then presses the handle 102 arranged on the operating frame 5 with one hand, thereby driving the cable 201 connected to the handle 102 at one end to move. Since the other end of the cable 201 is connected to the upper end of the first bent portion 2021 on the connecting rod 202, the inner side of the bent part of the first bent portion 2021 abuts against the lower end of the fixed shaft 10 arranged on one side of the micro-tillage machine body, and the connecting rod 202 is The second bent portion 2022 is hung on the pedal frame 8, so when the handle is pressed to drive the cable 201 to move, the cable 201 will apply a pulling force to the connecting rod 202, thereby driving the connecting rod 202 as a whole to swing around the fixed shaft 10 as the rotation center. At the same time, the second bent portion 2022 drives the pedal frame 8 to swing around the fork shaft 6 as the rotation center. When the pedal frame 8 swings in a clockwise direction, the fork shaft 6 of the clutch is subjected to the force transmitted by the pedal frame 8, and the fork shaft 6 drives the clutch to engage, thereby controlling the micro-tiller to travel. At this time, the return spring 7 arranged between the fixed shaft 10 and the pedal frame 8 is in a stretched state.

[0038] When it is no longer necessary to operate the tiller, the handle 102 is released, and the handle 102 and the cable 201 are restored to their initial states. The cable 201 no longer applies tension to the connecting rod 202, so the connecting rod 202 no longer applies a force to the pedal frame 8 that can drive the pedal frame 8 to swing. At this time, the return spring 7 is no longer stretched and shrinks to a normal state, thereby driving the pedal frame 8 to swing counterclockwise to the initial position. The clutch fork shaft 6 is subjected to the force transmitted by the pedal frame 8, and the fork shaft 6 drives the clutch to disconnect, and the tiller no longer continues to move.
