[0002] Generally, the ecological weed control methods for grasslands are mainly weed cutting and spraying pesticides. Weed cutting is also mainly carried out on plants that are taller than the grass, such as shrubs. The roots of the plants are pulled out through digging equipment to achieve the weed control effect.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] like Figure 1-4 As shown, a forest grassland ecological impurity removal device comprises an operating rod 1, at the end of which a crossbar 11 is provided;
[0025] A clamp 3 is movably disposed at both ends of the crossbar 11, and an elastic member 4 is disposed on the clamp 3 for maintaining a predetermined spacing;
[0026] A support rod 2 is rotatably mounted on the operating rod 1 and has an insert rod 21 at its end. When the support rod 2 is rotated to a predetermined angle, the clamps 3 are moved closer to each other to clamp the shrub;
[0027] The clamp 32 is rotatably mounted on the clamp 3 to enclose the bushes.
[0028] Specifically, pedals are provided on both sides of the insertion rod 21, and a plurality of fixed rakes 31 are fixedly provided on the opposite side of the clamp 3. A groove for accommodating the support rod 2 is provided on the operating rod 1. The initial position of the support rod 2 is located in the groove, and the rotation axis of the support rod 2 is located in the middle and lower position of the operating rod 1. In the default state, the clamp 32 is opened to allow the shrubs to enter the clamp 3. At this time, the clamp 3 maintains a predetermined distance under the elastic support of the elastic member 4 and does not clamp the shrubs. Then, the support rod 2 is flipped to a predetermined angle, and the insertion rod 21 is inserted into the ground and fixed during the flipping process, and the shrubs are clamped by stepping on the pedals. The foot pedal is further reinforced. In the process of flipping the support rod 2, the two clamps 3 overcome the elastic potential energy of the elastic member 4 and approach each other, and clamp the shrubs, while driving the clamps 32 to approach each other to enclose the shrubs. At this time, the rotation angle of the support rod 2 is kept unchanged and the insertion rod 21 is used as a fulcrum. The two ends of the operating rod 1 are respectively the two ends of the lever. Since the rotating shaft of the support rod 2 is located in the lower middle part of the operating rod 1, the force arm from the clamp 3 to the insertion rod 21 is shorter, which saves effort. At this time, one end of the operating rod 1 is pressed down, so that the other end with the clamp 3 drives the shrubs to be pulled up.
[0029] In the above technology, through the special structural design of the support rod 2, the insertion rod 21 at the end of the support rod 2 is used as the fulcrum of the operating rod 1, and forms a labor-saving lever for pulling out shrubs with the operating rod 1. The swing stroke is adjusted by adjusting the distance between the insertion rod 21 and the clamp 3, which is convenient for the operator to adjust. At the same time, by rotating the support rod 2, the two clamps 3 are driven to approach each other to clamp the shrubs, thereby preventing the shrubs from slipping during the pulling process.
[0030] As an embodiment further provided by the present invention, cables 13 are provided on opposite sides of the clamps 3, and the cables 13 are pulled to bring the clamps 3 closer to each other.
[0031] Specifically, when pulling out shrubs, the two clamps 3 can be brought closer to each other by manually pulling the cable 13, or the cable 13 can be matched with the rotating shaft of the support rod 2 through the gear group, and the gear group can be driven to rotate when the rotating shaft rotates, and then the cable 13 is wound on the output gear in the gear group, so that the cable 13 is pulled as the support rod 2 rotates, thereby bringing the clamps 3 closer to each other.
[0032] As another embodiment further provided by the present invention, a cylinder 12 is provided on the operating rod 1 , and a cable 13 is wound around the cylinder 12 and connected to the support rod 2 .
[0033] The two ends of the operating rod 1 are respectively fixed to the clamp 3 and the support rod 2, and as the support rod 2 rotates from the initial position in the groove to the predetermined angle, the distance between the support rod 2 and the cylinder 12 gradually increases, so that the cable 13 is gradually pulled and tightened, thereby driving the two clamps 3 to approach each other. At this time, the rotation angle of the support rod 2 is kept unchanged and the insertion rod 21 is used as the fulcrum. The two ends of the operating rod 1 are respectively the two ends of the lever. Since the rotation axis of the support rod 2 is located in the lower middle position of the operating rod 1, the force arm from the clamp 3 to the rotation axis of the support rod 2 is shorter, which saves effort. At this time, one end of the operating rod 1 is pressed down, so that the other end with the clamp 3 drives the shrub to be pulled up. After the shrub is completely pulled out, the pedal is stepped on to keep the fulcrum of the insertion rod 21 unchanged, and the operating rod 1 is continued to be rotated downward, so that the angle between the operating rod 1 and the support rod 2 is reduced, and the distance between the cylinder 12 and the support rod 2 is shortened. The cable 13 is relaxed and the two clamps 3 are moved away from each other, loosening the shrub so that the shrub falls to the ground for easy collection.
[0034] As another embodiment further provided by the present invention, the clamp 32 includes an eccentric wheel 321 rotatably disposed on the clamp 3 and a clamping tooth 322 disposed on the eccentric wheel 321 .
[0035] Specifically, in the default state, the clamp 32 is opened so that the plant is located inside the clamp 3. When the outer diameter of the plant is wider, it contacts the eccentric wheel 321. Then, the clamp 3 is further moved toward the plant. The eccentric wheel 321 begins to rotate due to the friction from the trunk, and drives the teeth 322 to approach each other and enclose other branches of the plant. As an extension of the clamp 3, it can also clamp plants with a wider outer diameter.
[0036] As another embodiment further provided by the present invention, a rotating shaft for the clamp 3 to rotate is horizontally arranged on the cross bar 11 , the cross bar 11 passes through the clamp 3 , and a circular protrusion is arranged at the end of the cross bar 11 located outside the clamp 3 .
[0037] Specifically, the clamp 3 is rotationally connected to the cross bar 11 via a horizontally arranged rotating shaft, and the swing axis of the clamp 3 is perpendicular to the axis of the cross bar 11. Due to the elastic potential energy of the elastic member 4, both clamps 3 are driven to swing outward. At the same time, the clamp 3 is restricted by the circular protrusion block, so that the swing angle of the clamp 3 is fixed.
[0038] As another embodiment further provided by the present invention, a stopper 33 is rotatably provided on the clamp 3 , and the stopper 33 includes a limiting end 331 for pressing the eccentric wheel 321 and a control end 332 located between the circular protrusion block and the clamp 3 .
[0039] Specifically, the limit end 331 and the control end 332 are respectively located at the two ends of the abutment 33, and a torsion spring is provided in the middle of the abutment 33. In the default state, the clamp 3 maintains a predetermined distance through the elastic member 4. At this time, the clamp 3 is limited by the circular protrusion block and is pressed by the circular protrusion block, and the control end 332 is located between the circular protrusion block and the clamp 3 and is also pressed, so that the limit end 331 is lifted and does not press the eccentric wheel 321. As the two clamps 3 approach each other to clamp the bushes, the distance between the clamp 3 and the circular protrusion block increases until the control end 332 is no longer pressed. Under the elastic action of the torsion spring, the limit end 331 is pressed on the eccentric wheel 321. At this time, the clamp 32 has enclosed the bushes, and the limit end 331 limits the clamp 32 to prevent the clamp 32 from slipping off the bushes.
[0040] Working principle: In the default state, the clamp 32 is open to allow the bush to enter the clamp 3. At this time, the trunk of the bush contacts the eccentric wheel 321, and then the clamp 3 is further moved toward the bush. The eccentric wheel 321 begins to rotate due to the friction from the trunk, and drives the clamping teeth 322 to approach each other and enclose other branches of the bush, increasing the contact area with the bush. At this time, the clamp 3 maintains a predetermined distance under the elastic support of the elastic member 4 and does not clamp the bush. Then the support rod 2 is flipped to a predetermined angle, and the distance between the support rod 2 and the cylinder 12 gradually increases, so that the cable 13 is gradually pulled and tightened, thereby driving the two clamps 3 to approach each other. During the flipping process, the insertion rod 21 is inserted into the ground and fixed, and further reinforced by stepping on the pedal. The two clamps 3 overcome the elastic potential energy of the elastic member 4, approach each other and clamp the bush, and the support is maintained at this time. The rotation angle of rod 2 remains unchanged and the insertion rod 21 is used as the fulcrum. The two ends of the operating rod 1 are respectively the two ends of the lever. Since the rotating shaft of the support rod 2 is located in the lower middle position of the operating rod 1, the force arm from the clamp 3 to the rotating shaft of the support rod 2 is shorter, which saves effort. At this time, one end of the operating rod 1 is pressed down, so that the other end with the clamp 3 drives the shrub to be pulled up. After the shrub is completely pulled out, the pedal is stepped on to keep the fulcrum of the insertion rod 21 unchanged. At the same time, the operating rod 1 is continued to be rotated downward, so that the angle between the operating rod 1 and the support rod 2 is reduced, the distance between the cylinder 12 and the support rod 2 is shortened, the cable 13 is relaxed and the two clamps 3 are moved away from each other. The clamp 3 is restricted by the circular protrusion block, so that the clamp 3 swings to a certain angle and stops, and the abutment 33 no longer presses the eccentric wheel 321, and the clamp 32 is loosened, so that the shrub can fall loosely on the ground for easy collection.
[0041] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
