However, in the daily movement of the micro-tillage machine, the bottom of the ridging side plate is always in contact with the ground, which not only affects the convenience of the micro-tillage machine's movement, reduces the balance of the micro-tillage machine, and increases the difficulty of operation, but also the ridging side plates are continuously worn and easily damaged, thereby reducing the service life of the ridging side plates, thereby reducing the use effect of the micro-tillage machine. Utility Model Content

[0005] In order to improve the use effect of the micro-tillage machine, the utility model provides a ridging device.

[0006] The present application provides a ridging device, which adopts the following technical solution:

[0007] A ridging device comprises a cross bar and a ridging plate arranged on the cross bar, wherein the cross bar is provided with a moving wheel, and the cross bar is provided with a lifting mechanism for driving the moving wheel to rise and fall, wherein the lifting mechanism comprises:

[0008] A guide block, wherein the guide block is arranged on the cross bar;

[0009] A mounting rod, wherein the mounting rod is vertically slidably disposed on the guide block, and the moving wheel is rotatably disposed on the mounting rod;

[0010] A first locking member, which is disposed on the guide block and is used to position the mounting rod;

[0011] A second locking member is provided on the mounting rod and is used to adjust and lock the position of the moving wheel.

[0012] By adopting the above technical solution, the first locking piece is unlocked, the moving wheel is driven to rise and fall by moving the mounting rod, and then the first locking piece is locked; the position of the moving wheel is fine-tuned and locked by the second locking piece to ensure that the moving wheel is in a suitable position on the ridging board, thereby maintaining the overall balance, making the ridging machine easier to operate, and making it easier for the ridging machine to go straight, and also reducing the probability of wear of the ridging board, extending the service life of the ridging board, thereby improving the use effect of the micro-tillage machine.

[0013] Optionally, a vertical movable cavity is provided on the guide block, the mounting rod is slidably inserted into the movable cavity, the first locking member is a locking bolt, a first threaded hole is provided on the guide block, and the locking bolt is threadedly connected in the first threaded hole.

[0014] By adopting the above technical solution, the mobile mounting rod slides in the mobile cavity until the height of the mobile wheel meets the usage requirements, the rotating locking bolt is threadedly connected in the first threaded hole and extends into the mobile cavity and presses against the mounting rod for positioning, and the locking bolt can be unlocked by rotating it in the reverse direction during adjustment, thereby achieving the convenience of moving and positioning the mounting rod.

[0015] Optionally, a mounting tube is provided at the bottom end of the mounting rod, and a mounting groove extending forward and backward and opening downward is provided in the mounting tube, an adjusting rod is rotatably arranged in the mounting groove, the movable wheel is rotatably arranged on the adjusting rod, and the second locking piece is arranged on the mounting tube and is used to position the adjusting rod.

[0016] By adopting the above technical solution, the mobile mounting rod is used to perform a preliminary adjustment on the height of the moving wheel, and then the adjusting rod is pushed, the adjusting rod rotates to drive the moving wheel to rise and fall, and then the adjusting rod is positioned by the second locking piece, and the position adjustment of the moving wheel in the vertical direction is achieved by the cooperation of the adjusting rod and the mounting rod, thereby reducing the probability that the stability of the moving wheel will be reduced due to the long length of the mounting rod. At the same time, the cooperation between the first locking piece and the second locking piece improves the working stability of the moving wheel, thereby improving the working stability of the micro-tillage machine, thereby improving the use effect of the micro-tillage machine.

[0017] Optionally, a second threaded hole is provided on the mounting tube, and the second locking member is a locking rod, which is threadedly connected in the second threaded hole and hinged to the adjusting rod at the lower end, and a T-shaped handle is coaxially provided on the top end of the locking rod for easy rotation.

[0018] By adopting the above technical solution, after the initial adjustment of the mounting rod, the locking rod is rotated by leveraging the T-handle, the locking rod rotates and drives the adjusting rod to rotate, and the adjusting rod rotates to drive the moving wheel to move, so as to achieve the re-adjustment of the position of the moving wheel, thereby reducing the installation length of the mounting rod. The locking bolt cooperates with the locking rod to increase the adjustment range of the moving wheel in the vertical direction, and at the same time improves the working stability of the moving wheel, thereby improving the use effect of the micro-tillage machine.

[0019] Optionally, the locking rod extends obliquely upward and backward.

[0020] By adopting the above technical solution, the locking rod is rotated to adjust the position of the moving wheel. When the moving wheel is working, the force received is vertically upward, while the locking rod is inclined downward under the action of the moving wheel, and is decomposed into a horizontal force and a vertical force. This not only reduces the probability of the locking rod being locked unstable due to direct impact of the vertical force, but also the horizontal force improves the convenience of moving the moving wheel forward, thereby improving the working stability of the moving wheel.

[0021] Optionally, a tensioning spring is coaxially sleeved on the locking rod, a limiting plate is coaxially fixed on the locking rod, the top end of the tensioning spring abuts against the limiting plate and the bottom end abuts against the mounting tube.

[0022] By adopting the above technical solution, when the moving wheel needs to be adjusted downward, the locking rod is rotated to push the adjusting rod to rotate and drive the moving wheel to move downward. At this time, the tensioning spring is compressed under the limit of the limiting plate and the mounting tube. After the moving wheel is adjusted to a suitable position, the tensioning spring is pressed tightly between the limiting plate and the mounting tube to improve the stability of the locking rod. When the moving wheel needs to be called back, the rotating locking rod drives the adjusting rod to move back. At this time, the tensioning spring rebounds and continues to press between the limiting plate and the mounting tube, thereby improving the stability of the locking rod.

[0023] Optionally, the guide block is detachably arranged on the crossbar via a connecting assembly, and the connecting assembly comprises:

[0024] A connecting tube, wherein the connecting tube is horizontally slidably sleeved on the cross bar;

[0025] A support rod, the support rod is arranged on the connecting tube and extends downward, and the guide block is arranged on the support rod;

[0026] A connecting bolt is threadedly connected to the connecting cylinder and the inner end of the connecting bolt is pressed against the cross bar.

[0027] By adopting the above technical solution, the connecting bolt is rotated to disengage from the cross bar, and then the support rod is pulled to drive the connecting tube to move. The horizontal position of the moving wheel can be adjusted by adjusting the position of the support rod. The supporting rod is directly pulled to drive the connecting tube to disengage from the cross bar, and the moving wheel can be replaced as a whole, thereby improving the convenience of installing and adjusting the position of the moving wheel.

[0028] Optionally, the ridging plate is arched, and the height of the front end of the ridging plate is greater than the height of the rear end.

[0029] By adopting the above technical solution, the movement of the moving wheel drives the ridging board to ridge the soil. The front end of the ridging board ridges the soil, and the soil is compacted under the action of the rear end of the ridging board, thereby improving the stability of the ridge, thereby improving the use effect of the micro-tillage machine.

[0030] Optionally, the rear end of the ridging board is serrated.

[0031] By adopting the above technical solution, the upper surface of the ridge soil becomes serrated under the action of the ridging plate, thereby reducing the probability of the top soil sliding off due to the smooth top of the ridge, thereby improving the stability of the ridge and improving the ridging effect.

[0032] Optionally, a plurality of reinforcing ear plates are provided on the ridging plate.

[0033] By adopting the above technical solution, the ear plates are strengthened to improve the rigidity and stability of the ridging plates.

[0034] In summary, the present application includes at least one of the following beneficial technical effects:

[0035] Unlock the first locking piece, and then the mounting rod can be moved to drive the moving wheel to rise and fall, lock the first locking piece, and adjust and lock the position of the moving wheel again through the second locking piece, so that the distance between the bottom end of the ridging board and the ground is greater than the distance between the moving wheel and the ground when the ridging operation is performed. When the ridging operation is performed, the position of the moving wheel is adjusted so that the ridging board descends and meets the appropriate ridging height, thereby maintaining the overall balance, making the operation easier, and making it easier for the ridging machine to walk straight. At the same time, the probability of wear of the ridging board is reduced, and the service life of the ridging board is extended, thereby improving the use effect of the micro-tillage machine.
