Description

Technical Field

[0001] This utility model relates to the field of municipal road technology, and in particular to a self-propelled integrated machine for pruning and crushing roadside trees on highways. Background Technology

[0002] Highway roadside trees, being tall trees planted in roadside green belts, were already 4-5 meters tall when planted before the highway opened to traffic. After the highway was completed and opened to traffic, they grew vigorously under the careful care of professional maintenance teams, including fertilization, watering, and weeding. After 5 or 6 years, the fast-growing branches extended into the emergency lane, gradually affecting driving safety. Currently, the pruning of highway roadside trees in China is mostly carried out by one crane and one truck with 7 or 8 workers using chainsaws or even manual felling, and then transporting the felled trees by truck. In the past two years, some workers have also used electric felling tools when pruning the branches of roadside trees. Both chainsaws and electric saws are very heavy, requiring workers to stand in the crane bucket to work manually. This is inconvenient for workers to carry and operate, resulting in high labor intensity, low work efficiency, and safety hazards. In addition, the construction occupies the road for a long time, affecting traffic efficiency.

[0003] In the prior art, Chinese patent (CN207969413U) discloses a forestry branch pruning device. The above device requires personnel to work at height, which is not safe enough, and it cannot collect and centrally process the pruned branches and leaves. Secondly, the electric saw is directly installed and fixed on the equipment. The electric saw vibrates a lot during operation, which directly affects the equipment below, causing great damage to the equipment and affecting the service life of the entire equipment.

[0004] Therefore, how to provide a self-propelled highway roadside tree pruning and shredding machine with a simpler and more reasonable structural design, better collection and processing of pruned branches and leaves, better reduction of the impact of chainsaw vibration on the equipment to improve equipment lifespan, and safer operation has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to provide a self-propelled highway roadside tree pruning and shredding machine with a simpler and more reasonable structural design, which can better collect and process pruned branches and leaves, better reduce the impact of chainsaw vibration on the equipment to improve the equipment life, and make operation safer.

[0006] To achieve the above objectives, this utility model provides a self-propelled highway roadside tree pruning and crushing integrated machine, including a walking device at the lower end; a robotic arm is installed on the walking device, and a chainsaw device is installed on the operating end of the robotic arm with a mounting and fixing structure; the machine is characterized in that a crusher is also installed on the walking device for crushing branches, and a branch collection hopper with a rectangular box structure and an open upper side is installed on the crusher, such that the branch collection hopper is located below the chainsaw device; the branch collection hopper is inclined outward and upward, and the lower end of the branch collection hopper is the material output end and connected to the feed port of the crusher; a winch is connected to the material output port of the crusher, and the winch has a winch discharge cylinder inclined outward and downward.

[0007] In this way, when the aforementioned self-propelled highway roadside tree pruning and shredding machine is in operation, the robotic arm enables the chainsaw device to prune the branches of the roadside trees. The pruned branches fall into the branch collection hopper and enter the shredder for shredding. The shredded branches are then output from the hoist discharge cylinder by the action of a winch and sent to the outside of the highway. The above-mentioned equipment can better collect and process the pruned branches and leaves on-site.

[0008] As an optimization, the walking device includes a horizontally arranged rotating platform at the upper end, on which the robotic arm and the crusher are mounted.

[0009] By mounting the robotic arm and shredder on a rotating platform, the entire unit can rotate horizontally, allowing for better control of the position and angle of the robotic arm and shredder, thus enabling better completion of the branch pruning operation.

[0010] Furthermore, an operator's cab is also provided on the rotating platform; the robotic arm is installed in the middle of the rotating platform, while the crusher and the operator's cab are installed at opposite ends of the rotating platform.

[0011] In this way, the positions of the crusher, the cab, and the operator's cab on the rotating platform are more rationally arranged.

[0012] As an optimization, a longitudinal movement drive mechanism is provided between the rotating table and the crusher, which can drive the crusher to move longitudinally on the rotating table.

[0013] In this way, the designed longitudinal movement drive mechanism can drive the crusher to move longitudinally on the rotating platform, which can better adjust the position of the branch collection hopper on the crusher, so that it can better collect and process the pruned branches.

[0014] Furthermore, the longitudinal movement drive mechanism includes a longitudinal guide structure and a longitudinal drive mechanism disposed between the crusher and the rotating table; the longitudinal guide structure is realized by the cooperation of a longitudinal guide rail and a slider, and the longitudinal drive mechanism is realized by a longitudinally arranged longitudinal drive cylinder; by installing an L-shaped mounting plate on the rotating table, the cylinder end of the longitudinal drive cylinder is fixed on the mounting plate, and the piston rod end of the longitudinal drive cylinder is connected to the crusher.

[0015] In this way, the design of the longitudinal movement drive mechanism is simpler and more reasonable.

[0016] As an optimization, a horizontally arranged mounting plate is installed on the rotating platform; the robotic arm includes a lower operating arm, the lower end of which is hinged to the mounting plate via a mounting seat. A vertically arranged first drive cylinder is arranged between the mounting plate and the operating arm. The cylinder body of the first drive cylinder is hinged to the mounting plate via a first hinge seat, and the piston rod of the first drive cylinder is hinged to the distal end of the operating arm via a second hinge seat and can drive the operating arm to rotate vertically; a vertically arranged execution arm is hinged to the distal end of the operating arm.

The cylinder body of the second drive cylinder is hinged to the operating arm via a third hinge seat, and the piston rod of the second drive cylinder is hinged to the distal end of the execution arm via a fourth hinge seat and can drive the execution arm to rotate vertically; and the distal end of the execution arm forms the operation execution end.

[0017] In this way, the structure of the robotic arm is simpler and more reasonable, and the chainsaw device on the robotic arm can be more easily operated to prune branches.

[0018] As an optimization, the operating arm includes a lower section and an upper section, and the angle formed between the lower section and the upper section is set to an obtuse angle; the actuator arm includes a lower section and an upper section, and the angle formed between the lower section and the upper section is set to an obtuse angle.

[0019] This makes the structural design of the operating arm and the actuator arm more reasonable.

[0020] As an optimization, the mounting and fixing structure includes a mounting plate on which the chainsaw device is mounted and fixed; a connecting plate is provided at the operating end of the robotic arm, and the mounting plate and the connecting plate are fixed together by bolts; a shock-absorbing cavity is provided in the middle of the connecting plate, and the shock-absorbing cavity is filled with shock-absorbing particles made of rubber material; and a number of shock-absorbing rods are connected and provided on the lower end face of the mounting plate, such that the shock-absorbing rods are inserted into the shock-absorbing cavity.

[0021] In this way, the installation and fixing structure design is simpler and more reasonable. Under the action of the damping rod and damping particles inserted into the damping cavity, the damping can be better completed, so that the vibration transmitted from the chainsaw device to the robotic arm is smaller.

[0022] As an optimization, a ring-shaped mounting groove is provided along the edge of the upper surface of the connecting plate, and a shock-absorbing rubber washer is provided in the mounting groove, with the upper side of the shock-absorbing rubber washer fitting into a mating groove on the lower surface of the mounting plate.

[0023] In this way, by setting up shock-absorbing rubber washers, the vibration transmitted to the robotic arm can be further reduced.

[0024] As an optimization, the upper surface of the mounting plate has a ring of upwardly protruding mounting sleeves, and the chainsaw device has a cylindrical mounting end that is inserted into the mounting sleeve. A protective pad is provided between the mounting sleeve and the mounting end. Several threaded holes are provided on the outer circumferential surface of the mounting sleeve, and screws are provided in the threaded holes. The inner ends of the screws abut against the protective pads to push the protective pads inward and tightly adhere to the mounting end of the chainsaw device.

[0025] This makes it easier to disassemble and assemble the chainsaw device, and ensures that it is stable and reliable after installation.

[0026] In summary, the aforementioned equipment, by incorporating a crusher, a branch collection hopper, and a winch, can better collect and process pruned branches and leaves. Improved design of the installation and fixing structure further reduces the impact of chainsaw vibration on the equipment, extending its lifespan. Furthermore, it eliminates the need for personnel to work at heights, thus improving operational safety. Attached Figure Description
