Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery equipment, in particular to a hydraulic tillage depth adjustment mechanism. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] The micro-tillage machine is powered by a small diesel engine or gasoline engine, and has the characteristics of light weight, small size and simple structure. The micro-tillage machine is widely used in dry land, paddy fields, orchards, etc. in plains, mountainous areas and hills.

[0004] At present, most agricultural machinery is equipped with a rotary tiller at the rear of the mobile carrier. The tilling depth adjustment of the micro-tiller is mainly achieved by a resistance member arranged at the rear of the micro-tiller. In the prior art, such as a tilling depth adjustment mechanism and a micro-tiller with publication number CN218788964U, when the tilling depth needs to be adjusted, the resistance member is turned to rotate so that the resistance member overcomes the clamping force of the clamping member, thereby disengaging the limit groove from the positioning member, and the height position of the resistance member can be adjusted up and down to meet different tilling depth requirements. The existing solution for achieving adjustment through the resistance member requires stopping the micro-tiller and then turning the resistance member for adjustment. The start and stop of the micro-tiller takes time, and the adjustment of the tilling depth is not accurate. Utility Model Content

[0005] The utility model aims to provide a hydraulic tillage depth adjustment mechanism and a micro-tillage machine, which can at least solve the technical problem that the tillage depth adjustment of the existing micro-tillage machine affects the working efficiency.

[0006] To achieve the above-mentioned purpose, the utility model proposes a hydraulic tillage depth adjustment mechanism, including a frame, a support shaft is installed between the frames, a support is rotatably installed on the support shaft, a rotary tiller is installed at the end of the support, a hydraulic cylinder is fixedly installed at one end of the frame, a hydraulic rod is installed on the support and corresponding to the hydraulic cylinder, the hydraulic rod is movably installed in the hydraulic cylinder, and the end of the hydraulic cylinder is connected to the pull rod through a hydraulic pipe.

[0007] It is further configured that the frame side beams are symmetrically mounted to support the shaft cylinders.

[0008] It is further configured that the support shaft is rotatably mounted in the support shaft cylinder.

[0009] It is further configured that a rotary tillage transmission box is fixedly installed on the support, and a rotary tiller is installed at the end of the rotary tillage transmission box.

[0010] It is further configured that a pull rod is provided at one end of the support, and an adjustment button is installed on the pull rod.

[0011] It is further configured that driving wheels are installed at both ends of the support shaft.

[0012] It is further configured that a mounting rod is arranged at the front end of the hydraulic cylinder, a handlebar is arranged inside the mounting rod, a brake wire brake is arranged on the handlebar, and a guide wheel is arranged below the handlebar.

[0013] It is further configured that a mounting seat is provided at the rear end of the hydraulic cylinder, and a vehicle seat is installed on the mounting seat.

[0014] It is further configured that an engine is installed on the frame, and the engine is connected to a rotary tillage transmission box.

[0015] In addition, the utility model also provides a micro-tillage machine, including the hydraulic tillage depth adjustment mechanism.

[0016] Beneficial effects of one or more of the above technical solutions:

[0017] While the tilling blade is rotating and the carrier is moving, one arm operates the pull rod, the hydraulic rod lifts the support, and the support rotates around the frame, so that the rotary tiller rotates around the micro-tillage machine; the height adjustment of the rotary tiller can be completed with one hand. During the adjustment process, the operator does not need to leave the micro-tillage vehicle, and the height adjustment can be performed simultaneously with the operation of the micro-tillage machine. The distance adjustment controlled by hydraulic pressure is accurate. BRIEF DESCRIPTION OF THE DRAWINGS
