Description

Technical Field

[0001] The utility model belongs to the technical field of gardening and greening, and in particular relates to a greening pruning device for gardening and greening. Background Art

[0002] Landscaping is the creation of a beautiful natural environment and recreational space in a certain area by using engineering technology and artistic means, transforming the terrain, planting trees and flowers, constructing buildings, and arranging garden paths. It is called a garden; shrubs need to be regularly trimmed with the help of pruning tools.

[0003] Since conventional electric or oil-powered pruning tools have a relatively large deadweight, when pruning, the pruning tools need to be lifted by hand to overcome their deadweight and carried to the shrubs for repair, which results in the problem of a relatively large operating load for conventional pruning tools.

[0004] For this reason, we propose a kind of landscaping and greening pruning device to solve the above-mentioned problem. Utility Model Content

[0005] The utility model aims to solve the problem that conventional pruning tools have a relatively heavy operating load, and proposes a greening pruning device for gardening.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A greening pruning device for gardening comprises an air pump, an exhaust port of the air pump is fixedly connected to an air injection pipe, an outer end of the air injection pipe is fixedly connected to an air valve, a stepper motor is fixedly connected to the air pump, a rotor of the stepper motor is fixedly connected to a knob of the air valve, an air guide pipe is fixedly connected to the air valve, a grip pipe is fixedly connected to the air guide pipe, a cylinder is fixedly connected to the grip pipe, a piston is slidingly sealedly installed in the cylinder, a shearing frame is fixedly connected to the outer end of the cylinder, a knife holder is fixedly connected to the outer end of the piston, a tension spring is connected between the shearing frame and the knife holder, and the shearing frame is slidably connected to the knife holder. An air pump is used to deliver gas into an air injection pipe, which is then injected into an air valve through the air injection pipe, discharged into an air guide pipe through the air valve, discharged into a grip tube through the air guide pipe, and discharged into an air cylinder through the grip tube. Air pressure is used to act on a piston, causing the piston to overcome the elastic force of a tension spring and act on a knife holder to slide outward. At the same time, a stepper motor is used to drive an air valve to close the air injection pipe, and the knife holder is retracted by driving a tension spring, so that gas is discharged outward through the grip tube, the air guide pipe and the air valve. Similarly, the reciprocating operation is carried out, and the cylinder and the grip tube are held by hand to place the shearing frame and the knife holder on the target shrub for pruning. Compared with conventional pruning equipment, the operating load is reduced.

[0008] Preferably, a universal wheel is installed at the lower end of the air pump, so as to reduce the moving resistance of the air pump and facilitate its use on the roadside.

[0009] Preferably, the shear frame comprises a cutting block and a fixing seat, wherein the cutting block is evenly fixedly connected to the outer end of the fixing seat. When the knife holder slides on the fixing seat, the cutting block is used to stabilize the branch, so that the knife holder can cut the branch on the shear frame conveniently.

[0010] Preferably, the shear frame further comprises a guide sleeve, which is fixedly connected to the upper end of the fixing seat, so as to increase the stability of the sliding operation of the piston.

[0011] Preferably, the knife holder includes a frame body and a blade, and the blade is evenly fixedly connected to the outer end of the frame body. When the knife holder reciprocates, the blade and the cutting block are repeatedly closed and opened, and the blade is used to cut off the branches on the upper side of the cutting block, so as to facilitate pruning of the target branches.

[0012] Preferably, the tool holder further comprises a slide block, which is fixedly connected to the lower end of the frame body. The slide block is slidably connected to the fixed seat to increase the stability of the distance between the shearing frame and the tool holder.

[0013] Preferably, the gas valve comprises a valve housing, a valve core and a rotating shaft, wherein the valve core is movably mounted in the valve housing, and the rotating shaft is rotatably connected to the valve housing. When the valve core rotates, the valve core reciprocates to change the gas port of the valve housing, so that the shear frame reciprocates to block the gas injection pipe, thereby facilitating the reciprocating operation of the knife holder.

[0014] Preferably, the gas valve further comprises a rotating block, and the rotating block is fixedly connected to the valve core, so that the stepping motor can drive the valve core to rotate conveniently through the rotating block.

[0015] In summary, the technical effects and advantages of the utility model are as follows:

[0016] 1. Use an air pump to send gas into the air injection pipe, inject it into the air valve through the air injection pipe, discharge it into the air guide pipe through the air valve, discharge it into the grip tube through the air guide pipe, discharge it into the cylinder through the grip tube, use air pressure to act on the piston, so that the piston overcomes the elastic force of the tension spring and acts on the knife holder to slide outward, and at the same time use a stepper motor to drive the air valve to close the air injection pipe, use the tension spring to drive the knife holder to retract, so that the gas is discharged outward through the grip tube, air guide pipe and air valve, and similarly reciprocating operation, hold the cylinder and grip tube to place the shear frame and knife holder on the target shrub for pruning; compared with conventional pruning equipment, the operating load is reduced.

[0017] 2. When the knife holder reciprocates, the blade and the cutting block are repeatedly closed and opened, and the blade is used to cut off the branches on the upper side of the cutting block, making it convenient to prune the target branches. BRIEF DESCRIPTION OF THE DRAWINGS
