Maintenance management measures include watering, fertilizing, pruning and shaping, pest control, weed cleaning, and facility maintenance, etc.

[0003] The patent publication number "CN212660648U" discloses "a bottom branch pruning device for forestry", which includes a mobile pruning vehicle, a lifting and shearing mechanism, a sliding pruning mechanism, and a net installation mechanism. The mobile pruning vehicle includes a support plate, a telescopic positioning rod, support legs, and a runner.

[0004] In the above patent, it is difficult for the runner to play a fixing effect on the device during pruning. If the equipment is not effectively stabilized during high-speed greening pruning, then the equipment may be unstable in center of gravity, thus tilting and affecting the pruning effect.

[0005] Therefore, the present utility model provides a pruning device to solve the above problems. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, this application provides a pruning device, which solves the problems mentioned in the above background technique.

[0007] To achieve the above objectives, this application is realized through the following technical solutions: A pruning device includes a vehicle frame and a pushing mechanism. The pushing mechanism is arranged on the surface of the vehicle frame. A shearing mechanism is arranged above the pushing mechanism. A supporting mechanism is arranged at the bottom of the vehicle frame. The supporting mechanism includes a second servo electric cylinder and a support plate. The top of the support plate is fixedly installed at the output end of the second servo electric cylinder respectively. The top of the second servo electric cylinder is fixedly installed at the bottom of the vehicle frame respectively.

[0008] By adopting the above technical solution, the servo electric cylinder is a modular product with an integrated design of a servo motor and a lead screw, which converts the rotational motion of the servo motor into a linear motion. The second servo electric cylinder is fixedly installed at the bottom of the vehicle frame respectively. The second servo electric cylinder pushes the support plate fixed at the output end, and the support plate contacts the ground respectively to effectively stabilize the equipment. It realizes that if it is difficult to effectively stabilize the equipment during pruning, then the equipment may be unstable in center of gravity and tilt, affecting the pruning effect. It solves the problem that if the equipment is not effectively stabilized during high-speed greening pruning, then the equipment may be unstable in center of gravity and thus tilt, affecting the pruning effect.

[0009] Preferably, the pushing mechanism includes a first servo electric cylinder and a placement plate. The bottom of the placement plate is fixedly installed at the output end of the first servo electric cylinder. The limiting rods are fixedly installed on the surface of the vehicle frame respectively. The outer sides of the limiting rods are slidably connected inside the placement plate. The bottom of the first servo electric cylinder is fixedly installed on the surface of the vehicle frame.

[0010] By adopting the above technical solution, through the placement plate fixed at the output end of the first servo electric cylinder, the output end of the first servo electric cylinder pushes the placement plate to realize the function of raising and lowering. One end of the placement plate is slidably connected to the outside of the limiting rod, and the limiting rod prevents the placement plate from shifting.

[0011] Preferably, the shearing mechanism includes a servo hydraulic press and an annular frame. The two ends of the annular frame are fixedly installed at the output ends of the servo hydraulic press respectively. The two sides of the annular frame are rotatably connected with sliding rollers respectively. The surface of the annular frame is fixedly installed with a detachable shearing knife.

[0012] By adopting the above technical solution, the working principle of the servo hydraulic press is that the servo motor directly drives the gear pump to stop oil supply and the pressure is stable. The main shaft of the servo hydraulic press has high repeated positioning accuracy when descending. The shearing knife is a kind of tool steel and is one of the most widely used tool steels. The tool steel can still maintain high hardness and good red hardness at high temperature, and has high wear resistance and appropriate toughness. The servo hydraulic press can accurately push the annular frame fixed at the output end to adjust the diameter. The pushed annular frame realizes the effect of effectively fitting the diameter of the tree. The sliding rollers sliding in the annular frame can effectively prevent the surface of the tree from being squeezed and the sliding rollers can effectively provide an ascending effect. The annular frame fitting the outside of the tree cuts off the branches through the shearing knife fixed at the top.

[0013] Preferably, the servo hydraulic press of the shearing mechanism is fixedly installed in the placement plate of the pushing mechanism.

[0014] By adopting the above technical solution, the placement plate can effectively provide an effective working position for the servo hydraulic press.

[0015] Preferably, a detachable receiving box is fixedly installed at one end of the vehicle frame respectively.

[0016] By adopting the above technical solution, the cut branches can fall into the receiving box fixed at one end of the vehicle frame.

[0017] Preferably, wheels are rotatably connected to the bottom of the vehicle frame respectively, a hand push handle is fixedly installed on one side of the vehicle frame, and a counterweight is fixedly installed on the surface of the vehicle frame.

[0018] By adopting the above technical solution, the counterweight is a component used to balance the weight of mechanical equipment. Its function is to help the mechanical equipment operate more smoothly. Pushing the hand push handle fixed on one side of the vehicle frame, the hand push handle drives the wheels rotatably connected to the bottom of the vehicle frame to rotate for movement, and the counterweight fixed on the surface of the vehicle frame can effectively prevent the equipment from tilting.

[0019] This application provides a pruning device. The beneficial effects are as follows:

It solves the problem that if the equipment is not effectively stabilized during high - speed greening trimming, the equipment may have an unstable center of gravity and thus tilt, affecting the trimming effect.

[0031] Referring to Figures 1 to 5 , in one aspect of this embodiment, the pushing mechanism 2 includes a first servo electric cylinder 21 and a placement plate 22.

The pushing mechanism 2 uses the placement plate 22 fixed at the output end of the first servo electric cylinder 21 at the bottom. The output end of the first servo electric cylinder 21 pushes the placement plate 22 to achieve the function of raising and lowering. One end of the placement plate 22 is slidably connected to the outside of the limiting rod 23. The limiting rod 23 prevents the placement plate 22 from shifting in position, and the limiting rods 23 are respectively fixed on the surface of the vehicle frame 1.

[0032] Referring to Figures 1 to 5, in one aspect of this embodiment, the shearing mechanism 3 includes a servo hydraulic press 34 and an annular frame 31. The two ends of the annular frame 31 are respectively fixedly installed at the output end of the servo hydraulic press 34. Slide rollers 32 are respectively rotatably connected to both sides of the annular frame 31. A detachable shearing knife 33 is fixedly installed on the surface of the annular frame 31.
