Technical Field

[0001] The utility model relates to the technical field of railway maintenance equipment, in particular to a railway track tree pruning device. Background Art

[0002] Railways are an important means of transportation, and their safety and stability are crucial. While trees are often planted along railway lines, while beautifying the environment and providing ecological value, they can also become overgrown and impact the normal operation of the railway. For example, branches can intrude into railway lines, compromising train safety. Therefore, regular pruning of trees along railway lines is an essential part of railway maintenance.

[0003] Currently, railway departments typically use handheld pruning tools or common garden pruning machinery to prune trees along railway lines. These methods are not only inefficient but also pose safety risks, especially when pruning high branches, as workers need to climb high, increasing the risk of accidents.

[0004] Therefore, there is an urgent need for a railway tree pruning device to efficiently and safely prune railway trees. Utility Model Content

[0027] The present application is further described in detail below in conjunction with all the drawings and specific embodiments.

[0028] Reference Figure 1 The present invention provides a railroad tree pruning device for pruning trees on rails while traveling between rails. The railroad tree pruning device includes an excavator body 1, an attachment 2, and track wheels 3. Both the attachment 2 and the track wheels 3 can be mounted on the excavator body 1. The track wheels 3 can assist the excavator body 1 in traveling along the rails. The attachment 2 can be mounted on the excavator arm of the excavator body 1 and can move with the movement of the excavator arm to prune trees. It should be noted that the cab, track wheels, and other parts of the excavator body 1 are prior art and will not be further described in detail in this application.

[0029] Reference Figure 2 and Figure 3 The excavator body 1 includes a swing arm 11, an arm link 12, and an attachment connecting plate 13. Two arm links 12 are provided, one end of each arm link 12 being rotatably connected to the end of the swing arm 11. The attachment connecting plate 13 is located at the end of the arm link 12 away from the swing arm 11, and one end of the attachment connecting plate 13 is rotatably connected between the two arm links 12. The attachment 2 can be connected to the swing arm 11 and the attachment connecting plate 13. The arm link 12 can also be rotatably connected to the end of the telescopic cylinder provided on the swing arm 11 of the excavator body 1. As the telescopic rod is operated, the arm link 12 can drive the attachment 2 to swing.

[0030] The accessory 2 includes a connecting plate 21, an installation box 22, a crossbeam 23 and a cutter 24. There are two connecting plates 21, which are respectively arranged on both sides of the swing arm 11. One end of the two connecting plates 21 is rotatably connected to the swing arm 11, and the other end is rotatably connected to the accessory connecting plate 13. The swing of the arm connecting rod 12 can drive the accessory connecting plate 13 to swing, thereby driving the connecting plate 21 to swing with the connection position between the connecting plate 21 and the swing arm as the axis.

[0031] A mounting flange 211 is fixedly attached to one side of the connecting plate 21. A fixed plate 221 is rotatably connected to one side of the installation box 22. The fixed plate 221 is coaxially arranged and fixed with the mounting flange 211, allowing the installation box 22 to rotate relative to the connecting plate 21. A crossbeam 23 is fixed to the side of the installation box 22 away from the connecting plate 21. Multiple circular cutters 24 are provided. The rotation axis of the cutters 24 is in the same direction as the rotation axis of the installation box 22. The multiple cutters 24 are evenly arranged along the extension direction of the crossbeam 23 and are rotatably connected to the crossbeam 23.

[0032] During operation, the excavator body 1 can move along the extension direction of the rails, and the attachment 2 moves with the excavator body 1. The connecting plate 21 on the attachment 2 can be installed on the excavator body 1 through the attachment connecting plate 13 and the swing arm 11. As the arm link 12 and the excavator body 1 move, the beam 23 can be driven to swing or rotate, and the cutter 24 on the beam 23 can be rotated to trim trees. The mounting box 22 can drive the beam 23 to rotate and increase the trimming range. The excavator body 1 can drive the cutter 24 to move to different positions for efficient and large-scale tree pruning. Compared with traditional manual tree pruning, it can improve pruning efficiency, reduce the number of workers climbing up, and reduce the risk of accidents.

[0033] As an embodiment, a first hydraulic motor 25 is fixed to one end of the mounting box 22, and the first hydraulic motor 25 can provide power to drive the fixed plate 221 and the mounting box 22 to rotate relative to each other. Furthermore, four cutters 24 are provided, and two second hydraulic motors 26 are fixed to the side of the crossbeam 23 away from the cutter 24. The two second hydraulic motors 26 are respectively provided on both sides of the mounting box 22, and the second hydraulic motors 26 can drive the two cutters 24 to rotate. The hydraulic motor can provide sufficient power for the rotation of the mounting box 22 and the cutter 24. It should be noted that the structure of the first hydraulic motor 25 and the second hydraulic motor 26, as well as the structure of the hydraulic motor driving the rotating shaft to rotate are all existing technologies and will not be repeated in this application.

[0034] A bracket 31 is provided below the excavator body 1 , and the bracket 31 can be connected to the track wheel 3 , and the track can enable the excavator body 1 to move stably on the rail.

[0035] Specifically, the bracket 31 includes two crossbars 311, which are arranged in parallel and fixed within the excavator body 1. Two diagonal rods 312 are fixed to the sides of the crossbars 311. The diagonal rods 312 are arranged downwardly and tilted away from the crossbars 311. The ends of the two diagonal rods 312 are rotatably connected to a support rod 313. A plurality of track wheels 3 are provided, each of which is rotatably connected to the ends of the support rods 313. The track wheels 3 can cooperate with the rails, and the rotation of the support rods 313 can drive the track wheels 3 to rotate, thereby driving the excavator body 1 to move. A motor can be provided within the excavator body 1 to drive the support rods 313 to rotate. This is prior art and will not be further described in this application. It should be noted that the track wheels 3 are not essential components of the rail tree pruning device provided in this application. The crawler wheels provided by the excavator body 1 can also be used to move on the rails.

[0036] The implementation principle of the present invention is as follows: when working, the excavator body 1 can move along the extension direction of the rail, and the attachment 2 moves with the excavator body 1. The connecting plate 21 on the attachment 2 can be installed on the excavator body 1 through the attachment connecting plate 13 and the swing arm 11. As the arm link 12 and the excavator body 1 move, the crossbeam 23 can be driven to swing or rotate, and the cutter 24 on the crossbeam 23 can be rotated to prune trees. The mounting box 22 can drive the crossbeam 23 to rotate and increase the pruning range. The excavator body 1 can drive the cutter 24 to move to different positions for efficient and large-scale tree pruning. Compared with traditional manual tree pruning, the pruning efficiency can be improved, and the staff's climbing work can be reduced, thereby reducing the risk of accidents.

[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
