Description

Technical Field

[0001] This invention relates to the field of green belt pruning equipment, and more particularly to a highway partition tree pruning equipment. Background Technology

[0002] The main function of the central median strip on highways is to shield drivers from oncoming headlights at night, preventing them from interfering with the driver's vision and causing accidents. It also reduces airborne dust and beautifies the environment. However, the small trees and shrubs planted within the median strip grow rapidly and can easily obstruct drivers' vision, posing a significant safety hazard. Therefore, regular pruning is necessary. Existing highway median strip pruning equipment often produces branches that scatter across the roadside, causing pollution and affecting road safety. Therefore, this invention provides a highway median strip branch pruning device. Summary of the Invention

[0003] The present invention mainly addresses the technical problems existing in the prior art and provides a highway barrier tree branch pruning device that can effectively collect pruning waste and prevent branches from flying.

[0004] The present invention provides a highway tree branch trimming device, comprising a traveling gantry 1 and a trimming mechanism 2; The bottom of the traveling gantry 1 is equipped with electric traveling wheels 11, and the inner side of the traveling gantry 1 is provided with guide wheels 12. The guide wheels 12 are connected to the inner side of the traveling gantry 1 through elastic connectors 13. The cutting mechanism 2 includes a cutting gantry and side cutting blades 23, top cutting blades 24, a material feeder 25, and a guide plate 26, which are installed on the cutting gantry and arranged from front to back. The cutting gantry includes two side mounting plates 21 and a top connecting plate 22 connecting the two side mounting plates 21. The side cutting blades 23 are installed on the inner side of the two side mounting plates 21, and the top cutting blades 24 are installed on the top connecting plate 22. The material feeder 25 and the guide plate 26 are both installed between the two side mounting plates 21. The cutting mechanism 2 is connected to the traveling gantry 1 via the connecting rod 7 provided on the side mounting plate 21, so that it moves synchronously with the traveling gantry 1.

[0005] The advantages of this invention are as follows: (1) By setting up a walking gantry and a pruning mechanism, the present invention integrates a side pruning blade and a top pruning blade on the pruning mechanism, which can prune the side and top surfaces of vegetation at the same time, thereby improving pruning efficiency.

[0006] (2) By setting a material feeding component and a V-shaped material guide plate at the rear of the trimming mechanism, the material feeding component can push the branches and leaves cut off from the top surface backward, while the material guide plate can guide the branches that fall during the top surface trimming process to both sides and fall into the green belt, thereby preventing the pollution of the road by the trimming waste and ensuring road traffic safety.

[0007] (3) By setting guide wheels with elastic connectors, the present invention enables the traveling gantry to adapt to the slight bending and undulation of the track when moving along the guardrail, thus ensuring the stability of the equipment operation and the quality of trimming.

[0010] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0011] like Figure 1 - As shown in Figure 4: A highway tree branch trimming device, including a traveling gantry 1 and a trimming mechanism 2; The bottom of the traveling gantry 1 is equipped with electric traveling wheels 11, and the inner side of the traveling gantry 1 is provided with guide wheels 12. The guide wheels 12 are connected to the inner side of the traveling gantry 1 through elastic connectors 13. The electric walking wheels are used to move the entire device along the highway guardrail. The guide wheels 12 are used to cooperate with the guide rails on the guardrail to ensure walking stability.

[0012] The cutting mechanism 2 includes a cutting gantry and side cutting blades 23, top cutting blades 24, a material feeder 25, and a guide plate 26, which are installed on the cutting gantry and arranged from front to back. The cutting gantry includes two side mounting plates 21 and a top connecting plate 22 connecting the two side mounting plates 21. The side cutting blades 23 are installed on the inner side of the two side mounting plates 21, and the top cutting blades 24 are installed on the top connecting plate 22. The material feeder 25 and the guide plate 26 are both installed between the two side mounting plates 21. The side pruning blade is used to prune the sides of the vegetation. The top pruning blade is used to prune the top surface of the vegetation. The material feeding device is used to push the pruned branches and leaves backward, and the material guide plate is used to guide the pruning waste to move to both sides and finally be blocked by the side mounting plate 21 and fall into the soil at the bottom of the plant, preventing it from splashing onto the road. Generally, the traveling gantry 1 is connected to the middle of the pruning mechanism 2. Figure 2 To better illustrate the structure of the cutting mechanism 2, the traveling gantry 1 is moved forward appropriately, but the actual product should be installed in the middle of the cutting mechanism 2 to ensure balance.

[0013] The cutting mechanism 2 is connected to the traveling gantry 1 via the connecting rod 7 provided on the side mounting plate 21, so that it moves synchronously with the traveling gantry 1.

[0014] The side-cutting blade 23 includes a side-cutting blade assembly 231 and a side-cutting motor 232. The side-cutting motor 232 is mounted on the outside of the side mounting plate 21, and its output shaft extends to the inside of the side mounting plate 21 and is connected to the side-cutting blade assembly 231. The side-cutting motor 232 drives the side-cutting blade assembly 231 to rotate, thereby pruning the side of the vegetation.

[0015] The top trimming cutter 24 includes a top cutting blade assembly 241 and a top cutting motor 242. The top cutting motor 242 is mounted above the top connecting plate 22, and its output shaft extends below the top connecting plate 22 and is connected to the top cutting blade assembly 241. The top cutting motor 242 drives the top cutting blade assembly 241 to rotate, thereby trimming the top surface of the vegetation.

[0016] The material feeding component 25 includes a feeding motor 251, a rotating shaft 252, and several rake teeth 253. The rotating shaft 252 is rotatably mounted between two side mounting plates 21. The feeding motor 251 is mounted on the outside of the side mounting plates 21, and its output shaft is connected to the rotating shaft 252. The rake teeth 253 are evenly distributed on the rotating shaft 252 and are used to feed the material cut from the top surface backward and upward. When the feeding motor 251 is started, the rotating shaft 252 drives the rake teeth 253 to rotate, feeding the branches and leaves cut from the top surface and falling on the branches backward and upward, guiding them to the guide plate 26 to prevent them from accumulating on the branches.

[0017] The guide plate 26 is a V-shaped plate with its upper surface tilted forward to form a slope. The middle end of the plate is located at the front end of both sides, and the thickness of the plate increases from front to back.

[0018] This design allows branches and leaves cut from the top surface to be guided to both sides by the V-shaped guide plates 26 as they are pushed backward during pruning. They are then blocked by the side walls and slide down the slope into the green belt. The thickness of the guide plates 26 can increase from front to back to enhance their structural strength.

[0019] The elastic connector 13 includes a sleeve 131 and a return spring 132 disposed within the sleeve 131. A guide rod 122 is provided on the wheel frame 121 of the guide wheel 12, extending into the sleeve 131 and abutting against the return spring 132. This ensures that during movement, the traveling gantry 1 will not damage the guardrail due to the rigid connection of the guide wheel, or become stuck and unable to move forward due to the increased width of the guardrail.

[0020] The working process of this invention is as follows: The traveling gantry 1 moves stably along the highway guardrail via electric traveling wheels 11 and guide wheels 12. The trimming mechanism 2 moves accordingly, with its side trimming blades 23 and top trimming blades 24 pruning the sides and top surfaces of the vegetation in the green belt, respectively. The branches and leaves generated during pruning fall directly into the soil of the green belt from the sides; the branches and leaves from the top trimming fall onto the top of the vegetation in the green belt first, and are then pushed backward by the material feeding component 25, falling into the guiding range of the material guide plate 26. The material guide plate 26 then guides them to both sides, ultimately concentrating them back into the green belt, preventing branches and leaves from remaining on top of the vegetation and affecting its growth. This overall ensures the cleanliness and safety of the road.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
