Description

Technical Field

[0001] This invention belongs to the field of climbing plant control technology, and particularly relates to a control device for climbing plants. Background Technology

[0002] Climbing plants often beautify and serve practical purposes in human living environments, but in some cases, they can also cause adverse effects. For example, their roots can infiltrate gaps in roofing materials, damaging the waterproofing layer and leading to leaks and structural damage. Some climbing plants also twine around other trees and shrubs, covering their canopies and preventing them from receiving sufficient sunlight, causing them to slowly wither and die.

[0003] Chinese utility model patent CN212448102U discloses a drone for weeding image recognition. The device collects ground images through an image acquisition device at the bottom of the drone to identify the location of weeds, and then sprays pesticides at fixed points on the drone to achieve unmanned and precise weeding.

[0004] However, some climbing plants, such as the five-clawed golden dragon type of invasive alien plants, can cover the surface of tall or shrubby plants, and pesticide spraying can harm other plants.

[0005] In summary, there is a need for a control device that can remove climbing plants without affecting nearby plants. Summary of the Invention

[0006] The purpose of this invention is to provide a device for controlling climbing plants. This invention utilizes the flexibility of drones and the coordinated operation of its components to identify, locate, grasp, and cut climbing plants, achieving precise removal without affecting the technical effects of the plants to which the climbing plants are attached.

[0007] The technical solution adopted by the present invention to solve the above problems is: a control device for climbing plants, comprising:

[0008] A drone, on which an image acquisition device is fixedly connected;

[0009] The gripping assembly includes a first electric push rod fixedly connected to the top of the drone, a connecting plate fixedly connected to the telescopic end of the first electric push rod, and a clamping plate assembly disposed at the bottom of the connecting plate.

[0010] The cutting assembly includes a movable block movably connected to the bottom of the drone, a roller disposed on the connecting plate, a force transmission component disposed on the movable block, and a cutting blade disposed on the force transmission component.

[0011] The movable block has an inclined surface on the side facing the roller, and the inclined surface contracts inward from bottom to top and contacts the surface of the roller. When the movable block moves vertically upward, it is driven to move outward by the roller.

[0012] The force transmission component transmits the outward movement of the movable block to the cutting blade, causing the cutting blade to move inward.

[0013] The drone provides a mobile platform for the equipment, enabling it to move flexibly in the air and reach different heights and locations within the vegetation. The image acquisition device is used to acquire real-time image information of the plants; through image processing technology, it can identify and locate target plants, assisting the drone in navigation and operation of other components.

[0014] The first motorized push rod of the gripping assembly enables the vertical telescopic movement of the clamping plate assembly to grip the plant in the appropriate position. The connecting plate and clamping plate assembly are used to clamp and secure the climbing plant, enabling direct removal of the climbing plant through pulling action, and ensuring the plant's position remains stable during cutting, preventing slippage or displacement.

[0015] In the cutting assembly, the movable block, through contact and relative movement with the rollers, generates horizontal displacement, thereby moving the movable block outwards. The force transmission assembly transmits the horizontal movement of the movable block to the cutting blade, ensuring that the cutting blade can accurately reach the target position for cutting. The cutting blade is responsible for cutting off the clamped climbing plant, achieving effective removal of the plant.

[0016] A further preferred technical solution is that: the force transmission component includes a first horizontal bar fixedly connected to the outside of the movable block, a spring sleeved on the outside of the first horizontal bar and fixedly connected at one end to the movable block, a vertical bar located at the lower part of the drone, a first connecting rod hinged between the vertical bar and the first horizontal bar by a hinge, a second horizontal bar located below the first horizontal bar, and a second connecting rod hinged between the second horizontal bar and the vertical bar by a hinge.

[0017] A cutting blade is fixedly connected to the end of the second crossbar;

[0018] The side of the drone is fixedly connected to a second guide member, which is slidably connected to the first horizontal bar and the vertical bar, and the second guide member is fixedly connected to a spring.

[0019] The drone is fixedly connected to a landing gear at its bottom, and a first guide is fixedly connected to the landing gear, with the first guide being slidably connected to the second crossbar.

[0020] A further preferred technical solution is that the force transmission component is a U-shaped hydraulic device, which includes a hydraulic pipe, an upper hydraulic rod disposed on the upper side of the hydraulic pipe and used to connect to the outside of the movable block, a lower hydraulic rod disposed on the lower side of the hydraulic pipe and used to connect to the outside of the cutting blade, and a fixing rod disposed on the hydraulic pipe and fixedly connected to the lower side of the UAV.

[0021] A further preferred technical solution is that the clamping plate assembly includes two sets of clamping plates movably connected to the bottom of the connecting plate, and a second electric push rod for pushing the clamping plates is fixedly connected to the connecting plate.

[0022] A further preferred technical solution is that: a first guide groove is symmetrically provided at the bottom of the connecting plate, a first guide block is slidably connected inside the first guide groove, and the first guide block is simultaneously fixedly connected to the clamping plate and the telescopic end of the second electric push rod.

[0023] A further preferred technical solution is that: in the two sets of clamping plates, one clamping plate is provided with strip-shaped grooves at equal intervals, and the other clamping plate is provided with strip-shaped protrusions at positions corresponding to the strip-shaped grooves.

[0024] A further preferred technical solution is that the edges of the strip-shaped protrusion are rounded.

[0025] A further preferred technical solution is that: a second guide block is fixedly connected to the top of the movable block, and a second guide groove is opened at the bottom of the drone corresponding to the position of the second guide block and is slidably connected to the second guide block.

[0026] A further preferred technical solution is that the bottom of the landing gear is provided with an anti-slip pad.

[0027] A further preferred technical solution is that the cutting component is provided in two sets.

[0028] In summary, the present invention has the following advantages:

[0029] 1. This invention uses a clamping plate assembly to clamp and grasp climbing plants of the Five-Clawed Golden Dragon type. A first electric push rod drives the connecting plate to rise, and the clamping plate assembly on the connecting plate can pull the Five-Clawed Golden Dragon type climbing plants, thereby facilitating the removal of the Five-Clawed Golden Dragon type climbing plants. This effectively avoids the problem of harming other plants when removing the target plant by spraying chemicals.

[0030] 2. When the first electric push rod drives the connecting plate to rise, the rising connecting plate can also drive the roller to move together. When the roller rises, it will push the two sets of cutting blades to move in opposite directions simultaneously through the force transmission component, so as to facilitate the cutting of the already pulled climbing plants and thus quickly remove the climbing plants.

[0031] 3. The present invention also enhances the gripping effect on climbing plants of the five-clawed golden dragon type by using the cooperation of the strip-shaped protrusions and strip-shaped grooves of the clamping plate assembly. Attached Figure Description

A strip-shaped groove is equidistantly opened on one side of the clamping plate 103. A strip-shaped protrusion 106 is fixedly connected to the other side of the clamping plate 103 at the position corresponding to the strip-shaped groove, which can increase the gripping effect on climbing plants of the *Gynostemma pentaphyllum* type. The edges of the strip-shaped protrusion 106 are rounded.

The bottom of the drone 1 is provided with a second guide groove corresponding to the position of the second guide block 210 and is slidably connected to the second guide block 210. It can play a certain guiding role in the movement of the movable block 201. One side of the movable block 201 is designed with a slope and contacts the surface of the roller 209 on the same side.

[0054] The implementation principle of the control device for climbing plants in this embodiment is as follows: First, the motor drives the propeller 3 to rotate to take off the drone. Then, the image acquisition device 2 collects images of plants on the ground to identify the *Gynostemma pentaphyllum* type climbing plant. After identifying the target plant, the first electric push rod 101 pushes the clamping plate 103 closer to it. Then, two sets of second electric push rods 104 simultaneously push the two sets of clamping plates 103 to move towards the center, so that the *Gynostemma pentaphyllum* type climbing plant can be clamped and grasped. Then, the first electric push rod 101 is reversed and retracted, driving the connecting plate 102 to rise, so that the *Gynostemma pentaphyllum* type climbing plant can be pulled, thus facilitating the removal of the *Gynostemma pentaphyllum* type climbing plant. This effectively avoids the problem of harming other plants when removing the target plant by spraying chemicals. The cooperation between the strip-shaped protrusions 106 and the strip-shaped grooves can increase the grip on the *Gynostemma pentaphyllum* type climbing plant. The gripping effect is achieved. At the same time, during the process of the first electric push rod 101 driving the connecting plate 102 to rise, the rising connecting plate 102 can also drive the roller 209 to move together. The roller 209 will roll on the inclined surface of the movable block 201 when it rises, so that the movable block 201 can be squeezed. After the movable block 201 is compressed, it will drive the first horizontal bar 202 to move. Utilizing the hinge between the first horizontal bar 202 and the vertical bar 204 and the first connecting rod 205, and the hinge between the vertical bar 204 and the second horizontal bar 206 and the second connecting rod 207, it can push the two sets of cutting blades 208 to move towards each other at the same time, so as to facilitate the cutting of the five-clawed golden dragon type climbing plant, thereby preventing the target object gripped by the device from being too heavy and affecting its stable operation. At this time, the spring 203 will be compressed. Finally, the gripped and cut five-clawed golden dragon type climbing plant can be placed in the designated position. At this time, the spring 203 will push the movable block 201 to automatically reset.

[0055] In a preferred embodiment, an anti-slip pad is added to the bottom of the landing gear 4, which can improve the stability of the drone when it lands.
