DETAILED DESCRIPTION

[0022] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figures 1 to 7 The embodiments are described in detail.

[0023] The present embodiment provides a forestry pruning machine capable of collecting branches, as shown in the attached drawings, including a base 1 and a support frame 2. Rollers are arranged at the four corners of the lower surface of the base 1 to facilitate the movement of the pruning machine. A battery box is fixedly installed on the side of the upper surface of the base 1 away from the support frame 2. A battery is placed in the battery box to power a first motor 5, an electric telescopic rod 15, and a second motor 18. The first motor 5, the electric telescopic rod 15, and the second motor 18 are electrically connected to an external control unit and the battery through wires. Both sides of the upper surface of the base 1 are fixedly connected with The support frame 2 is provided with a vertical drive assembly on one side of the upper surface of the base 1 close to the support frame 2. The vertical drive assembly includes a limit frame 4, a first motor 5 and a first lead screw 6. The limit frame 4 is fixedly connected to the side of the upper surface of the base 1 close to the support frame 2. The first motor 5 is fixedly installed in the middle of the top of the limit frame 4 and the output end is penetrated through the lower surface of the limit frame 4. The first lead screw 6 is connected to the output end of the first motor 5 through a spline and is rotatably connected between the limit frame 4 and the base 1. A first lifting mechanism is vertically slidably connected between the two support frames 2 and the first lifting mechanism is provided. The mechanism is transmission connected with the vertical driving assembly. The first lifting mechanism includes a first lifting frame 7, a first card slot 8, a limit slider 9 and a first lead screw nut 10. First card slots 8 are provided on both sides of the first lifting frame 7, and the support frames 2 on both sides are vertically slidably connected in the two first card slots 8 respectively. The first lifting frame 7 is vertically slidably connected between the two support frames 2. The support frame 2 and the first card slot 8 are mutually engaged to ensure that the first lifting frame 7 remains in a vertical state when lifting, and the stability of the first lifting frame 7 is ensured. The number of limit sliders 9 is two and the two limit sliders 9 are two. The sliders 9 are respectively fixedly connected to the two ends of the bottom of the first lifting frame 7 close to the limiting frame 4. The two limiting sliders 9 are respectively sleeved on the two sides of the limiting frame 4 and can slide vertically, which can limit the first lifting frame 7. The first lead screw nut 10 is fixedly connected to the bottom end of the middle part of the first lifting frame 7 close to the limiting frame 4. The first lead screw nut 10 is connected to the outside of the first lead screw 6 through threaded transmission. When the first motor 5 drives the first lead screw 6 to rotate, it can drive the first lead screw nut 10 to move up and down, thereby realizing the lifting effect of the first lifting frame 7;

[0024] A second lifting mechanism is inserted into the interior of the first lifting mechanism, and a receiving mechanism for receiving tree branches is provided at the top of the side of the second lifting mechanism. A pull rope 3 for pulling the second lifting mechanism is fixedly connected to the top of the support frame 2, and the other end of the pull rope 3 is overlapped on the top of the first lifting mechanism and fixedly connected to the bottom of the second lifting mechanism. The second lifting mechanism includes a second lifting frame 11 and a second card slot 12. The second lifting frame 11 is vertically slidably connected to the interior of the first lifting frame 7 and second card slots 12 are opened on both sides. The two pull ropes 3 can be respectively inserted in the second card slots 12 adjacent to them. Pulleys 13 are rotatably connected to both sides of the top of the first lifting frame 7. The pull ropes 3 at the tops of the two support frames 2 are respectively overlapped on the pulleys 13 on both sides and close to the first lifting frame 7. One end of the second lifting frame 11 is fixedly connected to the inner bottom wall of the second slot 12. The pull rope 3 is made of a flexible steel wire rope. When the vertical driving assembly drives the first lifting frame 7 to rise, the pulleys 13 on both sides of the top of the first lifting frame 7 rise synchronously, thereby pushing the pull ropes 3 on both sides upward. Since one end of the pull rope 3 fixedly connected to the support frame 2 is in a fixed and immovable state, when the first lifting frame 7 moves upward, the end of the pull rope 3 away from the support frame 2 will also move upward, so that the pull rope 3 can pull the second lifting frame 11 in the first lifting frame 7 to move upward synchronously, so that the height of the pruning mechanism can be raised higher. By controlling the operation of the first motor 5, the pruning mechanism can be adjusted to different heights, which is convenient for pruning branches at different heights.

[0025] The receiving mechanism includes a side support frame 14, an electric telescopic rod 15, a receiving belt 16 and a lower support plate 17. The side support frame 14 is rotatably connected to the top of the second lifting frame 11 away from the limiting frame 4 through a hinge. The electric telescopic rods 15 are fixedly installed at both ends of the side support frame 14. The receiving belts 16 are fixedly installed between the fixed rod bodies and the movable rod bodies of the two electric telescopic rods 15. The receiving belt 16 is a belt-shaped structure with a certain deformation force, and its two ends are respectively two sleeves, which can be sleeved on the outside of the electric telescopic rods 15 on both sides, and the bolts pass through the sleeves and are tightened against the outside of the electric telescopic rod 15 to fix the whole to the outside of the electric telescopic rod 15; the lower support plate 17 is rotatably connected to the same side of the second lifting frame 11 as the side support frame 14 and is arranged below the side support frame 14. The top of the electric telescopic rod 15 abuts against the end of the lower surface of the side support frame 14 away from the second lifting frame 11, and the lower support plate 17 can support the side support frame 14 to ensure that the side support frame 14 is supported in a horizontal state, which is convenient for receiving the pruned branches, and the movable end of the electric telescopic rod 15 is also provided with a receiving belt 16. When the pruned branches are long, the movable end of the electric telescopic rod 15 can be controlled to extend outward, thereby expanding the receiving range of the receiving mechanism, and can more stably receive the cut branches; when the receiving mechanism is not needed, the movable ends of the electric telescopic rods 15 on both sides are retracted, and the side support frame 14 is lifted upward, and the lower support plate 17 below will be separated from the side support frame 14 and fall to a vertical state, and then the side support frame 14 and the electric telescopic rod 15 can be retracted downward into the second lifting frame 11;

[0026] A pruning mechanism for cutting branches is provided at the top of the second lifting mechanism, and the pruning mechanism includes a second motor 18, a second lead screw 19, a second lead screw nut 20, and a tool holder 21. A bracket 22 is fixedly connected to the upper surface of the second lifting frame 11. The second motor 18 is fixedly mounted on one side of the bracket 22 and the output end is passed through the inside of the bracket 22. The second lead screw 19 is connected to the output end of the second motor 18 through a spline and is rotatably connected to the inside of the bracket 22. The spiral directions of the external threads of the second lead screw 19 are oppositely arranged with the vertical center line of the second lead screw 19 as the boundary. The tool holder 21 is fixedly connected to the top of the second lead screw nut 20 and passes through the upper surface of the bracket 22 and can slide horizontally therein. The number of the second lead screw nuts 20 is two and two The two second lead screw nuts 20 are respectively connected to the two ends of the outside of the second lead screw 19 through threaded transmission. The two second lead screw nuts 20 and the tool holder 21 are symmetrically arranged with the vertical midline of the second lead screw 19 as the symmetry axis. The upper surface of the second lifting frame 11 is provided with a slide groove for limiting the second lead screw nut 20. The bottoms of the two second lead screw nuts 20 are both horizontally slidably connected in the slide groove, which can limit the second lead screw nut 20 and ensure that the second lead screw nut 20 can only move horizontally. When the second motor 18 drives the second lead screw 19 to rotate, the threads in opposite directions at both ends can drive the two second lead screw nuts 20 to move away from or close to each other synchronously, so that the tool holder 21 above can prune the branches, and the cut branches will fall on the receiving mechanism.

[0027] In summary, the steps for using the forestry pruning machine that can collect branches are as follows:

[0028] 1. Move the pruning machine to the bottom of the branch to be pruned, then lift the side support frame 14 and the electric telescopic rod 15 to a horizontal state, and rotate the lower support plate 17 to an inclined state, so that the top of the lower support plate 17 is pressed against the bottom of the side support frame 14, so that the side support frame 14 can be supported in a horizontal state;

[0029] 2. Then drive the first motor 5 to operate, so that the first screw 6 drives the first lifting frame 7 to rise, and at the same time, the second lifting frame 11 will rise synchronously under the action of the pull rope 3, and the knife holder 21 will stop rising after moving to both sides of the branches to be pruned;

[0030] 3. Control the second motor 18 to operate, drive the second screw nuts 20 and the tool holder 21 on both sides to approach each other to cut the branches, and adjust the extension length of the movable end of the electric telescopic rod 15 according to the length of the pruned branches. The cut branches will fall on the receiving belt 16 below, which can collect the branches and avoid injuring the staff.
