Description

Technical Field

[0001] This invention relates to the field of tree branch pruning equipment, and more particularly to a roadside tree branch pruning device for highways. Background Technology

[0002] Currently, some highways are built in mountainous areas, which leads to the growth of many shrubs and branches along the roadside, which can easily affect visibility and driving safety at road curves. To address this, we propose a highway roadside branch trimming device. Summary of the Invention

[0003] The present invention mainly addresses the technical problems existing in the prior art and provides a roadside tree branch trimming device for highways.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a highway roadside tree branch trimming device, the main body of which is a mobile device that travels inside the guardrail of the highway, has a support plate installed on the top of the mobile device. The outer side of the support plate is supported and connected to the mobile device through a support frame. The upper part of the outer side of the support plate also has a pressing push plate that can squeeze and push the tree branches. A guide plate is installed on the front side of the pressing push plate. The support plate and the pressing push plate are driven and supported by a cylinder support assembly. The front part of the inner side of the pressing push plate is provided with a first rectangular groove. The rear part of the first rectangular groove is provided with several second rectangular grooves arranged sequentially from front to back. There are interconnecting channels between the first rectangular groove and adjacent second rectangular grooves, as well as between any adjacent second rectangular grooves. A set of drive shafts is rotatably connected between several sets of interconnecting channels. A first mounting groove is opened on the front side inside the first rectangular groove. The front end of the drive shaft extends into the first mounting groove and is rotatably connected to the first mounting groove. A bushing is sleeved outside the area of ​​any second rectangular groove of the drive shaft. Several sets of cutting blades are installed around the outer side of any bushing.

[0005] The extrusion pusher plate has a housing with an internal motor installed on one side. The motor output shaft of the motor inside the housing, the outer periphery of the drive shaft inside the first rectangular groove and the outer periphery of the motor output shaft are both provided with teeth. The drive shaft and the motor output shaft are driven and fitted together by a drive toothed belt. An end cap is installed at one end of the motor output shaft.

[0006] This invention provides a roadside tree branch trimming device for highways. It has the following beneficial effects:

[0007] 1. This is a highway roadside tree branch trimming device. The mobile device can be controlled to move from one side of the guardrail. A pressing push plate is mounted on top of the mobile device via a cylinder support assembly on one side of a support plate. The pressing push plate is set at an inclined angle. In the default state, the pressing push plate can press and support the branches and shrubs on one side of the guardrail outwards. When the pressing push plate moves forward in conjunction with a guide plate, the guide plate continuously guides the branches. As the pressing push plate moves forward, the branches gradually bend away from the guardrail. Simultaneously, when the branches approach the guide roller, they undergo a lateral bend. At this point, when the motor inside the machine is started, it drives the drive shaft to rotate via a drive belt outside the motor output shaft. Multiple sets of cutting blades outside the drive shaft rotate within a second rectangular groove and perform high-speed multi-segment cutting on the laterally bent branches, causing the extended branches to be pulverized and fall off in segments. This achieves the effect of automatically cutting and pulverizing the branches extending from one side of the guardrail, avoiding obstruction of road visibility and ensuring road driving safety.

[0008] 2. A highway roadside tree branch trimming device, wherein multiple sets of guide rollers are provided on one side of the extrusion push plate, and the connecting shafts at both ends of the guide rollers are supported and connected by support arms. When the extrusion push plate moves forward in conjunction with the mobile device, the tree branches outside the guardrail will contact the outer periphery of the multiple sets of guide rollers, squeezing the tree branches to form a lateral bend. At the same time, the guide rollers will rotate when they contact and squeeze the tree branches, thereby reducing the frictional resistance between the tree branches and the extrusion push plate, thereby reducing the frictional resistance of the extrusion push plate and ensuring the stability of the extrusion push plate movement.

[0009] 3. This highway roadside tree branch trimming device, when the mobile device moves the extrusion pusher to cut and crush branches of different lengths, can use a signal control controller in conjunction with a solenoid valve to drive and control the cylinder, so that the hydraulic shaft is located inside the cylinder for extension and retraction control, driving the extrusion pusher to move left and right, so that the branches can be cut by appropriate contact extrusion, thereby achieving the effect of multi-functional cutting and adjustment.

[0010] 4. A photovoltaic panel is installed on one side of the support plate through the second mounting groove. When the mobile device is traveling normally and squeezing the tree branches by the squeezing push plate, the photovoltaic panel on one side of the support plate can face the sunlight and be heated, so as to provide continuous power to the device and thus improve the working efficiency of the device.

[0011] 5. Two sets of clamping arms are installed on one side of the mobile device. Each set of clamping arms is equipped with a limiting roller. The limiting roller is supported and engaged by a connector. The limiting roller engages with the rail grooves on the upper and lower sides of the guide rail plate for limiting rolling. As the mobile device moves, it can be limited by the limiting roller on one side of the clamping arm and the guide rail plate itself to avoid deviation and affect the cutting of the cutting tool inside the extrusion push plate, thereby ensuring the stability of the mobile device itself.

[0023] 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.

[0024] Example: A roadside tree trimming device for highways, such as Figures 1-7 As shown, the main body is a mobile device 2 traveling inside the guardrail 1 of a highway. A support plate 3 is mounted on the top of the mobile device 2. The outer side of the support plate 3 is supported and connected to the mobile device 2 via a support frame 4. The upper outer side of the support plate 3 also has a pressing push plate 5 that can squeeze and push tree branches. A guide plate 7 is mounted on the front side of the pressing push plate 5. The support plate 3 and the pressing push plate 5 are driven and supported by a cylinder support assembly 6. The front of the inner side of the pressing push plate 5 has a first rectangular groove 8, and the rear of the first rectangular groove 8 has several second rectangular grooves arranged sequentially from front to back. The first rectangular groove 8 and the adjacent second rectangular groove 9 are provided with interconnecting channels 10. A set of drive shafts 11 are rotatably connected between several sets of the interconnecting channels 10. A first mounting groove 12 is provided on the front side inside the first rectangular groove 8. The front end of the drive shaft 11 extends into the first mounting groove 12 and is rotatably connected to the first mounting groove 12. A bushing 13 is sleeved on the outside of the area of ​​the drive shaft 11 located in any second rectangular groove 9. Several sets of cutting tools 14 are installed on the periphery of any bushing 13.

[0025] The extrusion push plate 5 is mounted on one side of a housing 15 containing a motor. The motor output shaft 16 of the motor inside the housing 15 is provided with teeth 17 on the outer periphery of the drive shaft 11 inside the first rectangular groove 8 and the outer periphery of the motor output shaft 16. The drive shaft 11 and the motor output shaft 16 are driven and fitted together by a drive belt 18. An end cap 19 is installed at one end of the motor output shaft 16.

[0026] Here, the mobile device 2 is essentially a small vehicle that slowly moves along the guardrail, changing the direction of the branches through the guide plate and the extrusion pusher plate, and then cutting the branches with the rotating cutting blade 14. (It should be noted that since this is the tip of the branch, it is relatively flexible and easily bent and deformed.) Specifically, the extrusion pusher plate 5 is set at an inclined angle outside the support plate 3, and the guide plate 7 is an arc-shaped plate. When the mobile device 2 moves on one side of the guardrail 1, the support plate 3 drives the extrusion pusher plate 5 and the guide plate 7 to extrude and push the branches through the cylinder support assembly 6.

[0027] Both the drive shaft 11 and the motor output shaft 16 are engaged with the drive belt 18 via teeth 17. When the motor inside the housing 15 starts and drives the drive belt 18 to rotate via the motor output shaft 16, the drive shaft 11 drives the cutting tool 14 outside the bushing 13 to rotate and cut inside the second rectangular groove 9 via the drive belt 18. The rotating cutting tool 14 cuts the branches.

[0028] Furthermore, a number of guide rollers 20 are provided on the outer side of the extrusion pusher plate 5. The upper and lower ends of the guide rollers 20 are equipped with connecting shafts 21. A connecting sleeve 22 is rotatably sleeved on the outside of the connecting shaft 21. A support arm 23 that is supported and connected to the extrusion pusher plate 5 is fixedly installed on the outside of the connecting sleeve 22.

[0029] When the mobile device 2 moves the extrusion pusher 5, one side of the extrusion pusher 5 is in a state of extrusion and rolling material guidance with the tree branch through a number of sets of guide rollers 20.

[0030] The essence of the guide roller 20 is that the original sliding friction between the tree branch and the extrusion push plate 5 is transformed into rolling friction between the tree branch and the guide roller 20. Generally speaking, the tree branch will generate a large restoring force after deformation, which will lead to an increase in the friction between it and the extrusion push plate 5.

[0031] The cylinder support assembly 6 is composed of a cylinder 24 and a hydraulic shaft 25 that extend and retract together. A solenoid valve 26 that cooperates with the pneumatic control of the cylinder 24 and a controller 27 that controls the start of the cylinder 24 by signal control are installed on one side of the support plate 3.

[0032] When the controller 27, in conjunction with the solenoid valve 26, starts the cylinder 24, the hydraulic shaft 25, located inside the cylinder 24, drives the extrusion push plate 5 to extend and retract. Here, the cylinder support assembly 6 is mainly used to adjust the depth and tilt of the extrusion push plate 5. It should be noted that the cylinder 24 and the extrusion push plate 5 are hinged.

[0033] The support plate 3 has a second mounting groove 28 on its inner side, and a photovoltaic panel 29 that is heated by sunlight is installed inside the second mounting groove 28. This is mainly used for power supplementation, and the photovoltaic panel is generally equipped with a battery.

[0034] A guide rail plate 30 is installed on the inner side of the guardrail 1, and two sets of clamping arms 31 are installed on the outer side of the mobile device 2. Two sets of connectors 32 are installed between the two sets of clamping arms 31. A round shaft 33 is rotatably arranged between each pair of connectors 32. A limiting roller 34 is sleeved on the outside of the round shaft 33. The guide rail plate 30 has rail grooves 35 on both the upper and lower sides.

[0035] Both sets of clamping arms 31 are connected and rolled together by limiting rollers 34 and the rail grooves 35 on the upper and lower sides of the guide rail plate 30.

[0036] This area is mainly used to guide the movement of mobile device 2. It should be noted that the guardrail may need to be stamped here, but compared to the cost per kilometer of highway construction, the cost of modifying the guardrail is negligible.

[0037] Working principle of the invention:

[0038] The mobile device 2 can be controlled to move from inside the guardrail 1. Above the mobile device 2, a pressing plate 5 is mounted on the cylinder support assembly 6 on the outer side of the support plate 3. The pressing plate 5 is set at an inclined angle. In the default state, the pressing plate 5 can press and support the branches and shrubs outside the guardrail 1 outwards. When the pressing plate 5 moves forward in conjunction with the guide plate 7, the guide plate 7 continuously guides the branches. As the pressing plate 5 moves forward, the branches will be compressed and bent. Simultaneously, when the branches are pressed close to the guide roller 20, they will bend laterally. At this time, when the motor inside the housing 15 starts, it can drive the drive shaft 11 to rotate through the drive belt 18 outside the motor output shaft 16. Multiple sets of cutting blades 14 outside the drive shaft 11 can then rotate inside the second rectangular groove 9 and perform high-speed multi-segment cutting on the laterally bent branches. This pulverizes and falls the extending branches in segments, avoiding obstruction of road visibility and ensuring road safety. The multiple sets of guide rollers 20 rotate when they contact and compress the branches, reducing the frictional resistance between the branches and the pressing plate 5.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. 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. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
