Description

Technical Field

[0001] This invention relates to the field of landscape beautification technology, specifically to a pruning device for landscape construction. Background Technology

[0002] In municipal greening projects, there are more and more green seedlings on both sides of urban roads, in gardens and along highways. Hedges have the functions of isolation and protection, shielding unfavorable views, dust prevention and noise reduction, and beautifying the urban environment. However, hedges are seasonal plants with different growth characteristics and different growth patterns. They must be trimmed manually with shears or handheld hedge trimmers to ensure that the hedges do not affect road traffic safety and also have a certain aesthetic appeal to beautify the city.

[0003] Existing garden pruning equipment requires workers to slow down its operation in areas with high hedge density due to varying hedge densities. This allows sufficient time for the equipment to prune the hedges. However, the large blind spots make it difficult to adjust the equipment speed based on the density in real time. Furthermore, different hedge heights necessitate the use of different pruning equipment. Therefore, we propose a garden pruning device. Summary of the Invention

[0004] The purpose of this invention is to provide a pruning device for garden construction, in order to solve the problems mentioned in the background art, such as the need for workers to slow down the operation speed of the pruning device when facing areas with high density, so that the pruning device has enough time to prune the hedges, and the need to use different specifications of pruning devices when pruning hedges of different heights.

[0042] Example 2

[0043] like Figure 1-2 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that a coupling 15 is fixedly connected to the middle of the top of the placement box 211, which can fix the position of the coupling 15. A rotating motor 16 is fixedly connected to one end of the coupling 15, which can fix the position of the coupling 15.

[0044] The following is a further introduction to the specific working method, as detailed in the following description: Specifically, when the garden construction pruning equipment is working, the contact plate 14 comes into contact with the hedge, the lifting device 18 is lowered, the pressure between the contact plate 14 and the hedge increases, the contact plate 14 is subjected to force to squeeze the third spring rod 13 and then squeeze the pressure sensor 12, when the pressure sensor 12 reaches the preset value.

[0045] When the bottom of the hedge is not completely covered, the electric push rod 301 is activated. The electric push rod 301 pushes the sliding plate 302 and the placement plate 303 downward. When the placement plate 303 descends to the corresponding position, the pneumatic rod 310 is activated. The pneumatic rod 310 pushes the placement plate 303 to move, which can drive the contact plate 309 to move. The contact plate 309 drives the first spring rod 308 to stretch. The movement of the placement plate 303 pushes the second movable shear tooth 305 to move. The protruding plate 306 on the surface of the second movable shear tooth 305 engages with the connecting ring 214 on the surface of the first movable shear tooth 213, making the first movable shear tooth 213 and the second movable shear tooth 305 a whole. The fixed motor 216 is activated. The fixed motor 216 drives the first movable shear tooth 213 and the second movable shear tooth 305 to move under the first fixed shear tooth 212 and the second fixed shear tooth 304 through the crank 215, thereby cutting the hedge.

[0046] The rotating plate 203 moves inward under the force of the hedge branches. The rotating plate 203 drives the connecting piece 204 to rotate. The connecting piece 204 drives the steel cable 205 to move. The steel cable 205 moves through the fixed rod 206 and drives the pulling plate 207 to move. The moving plate 207 presses against the moving plate 208. The moving plate 208 moves on the surface of the fixed plate 210 under the force. The moving plate 208 pushes the slider to move on the surface of the sliding rheostat 209, causing the resistance of the sliding rheostat 209 to change, thereby adjusting the operating speed of the device (the operation of the rotating motor 16 or the movement of the traction device).

[0047] When the device switches from rotation to movement, if both pressing plates 10 are subjected to the squeezing force from the hedge branches, they will move inward. The movement of the two pressing plates 10 can cause the second spring rod 9 to extend and retract. When both contact switches 8 are subjected to the squeezing force from the pressing plates 10, the traction device is paused through the control device 11.

[0048] All of the above electronic devices are powered by internal batteries (not shown) or external wires (not shown).
