DETAILED DESCRIPTION

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1-2 As shown, a weeding device for forestry and grassland ecological protection includes a cart 1, a driving member 6 and a weeding blade 8, and the device also includes:

[0028] The top of the cart 1 is provided with a plurality of movable rods 2 that move up and down. There are two sets of movable rods 2. A set of auxiliary wheels 3 is installed on one set of movable rods 2. The direction of the auxiliary wheels 3 is the same as that of the wheels on the cart 1.

[0029] Connecting rod 4, each set of movable rods 2 is provided with a connecting rod 4, and the other end of the connecting rod 4 is provided with a ring 5;

[0030] The rotating member 7 includes a rotating shaft 71, which is installed at the output end of the driving member 6. The other end of the rotating shaft 71 is movably connected to a connecting shaft 72. The ring 5 is movably sleeved on the outer periphery of the connecting shaft 72. Two discs 73 are fixed on the outer periphery of the connecting shaft 72. The ring 5 is located below the disc 73 and presses against the disc 73.

[0031] In one aspect of this embodiment, the driving member 6 may be a motor, or a member capable of driving the rotating member 7 to rotate.

[0032] In actual application, the movable rods 2 move up and down with the change of the terrain of the grassland. When the cart 1 moves to a position of a soil slope with a large slope, after the wheels at the front end of the cart 1 pass the highest point of the soil slope, the group of auxiliary wheels 3 close to the moving direction of the cart 1 drive the several movable rods 2 connected thereto to slowly move up. When the several movable rods 2 move up, the connecting rod 4 drives the circular ring 5 to move up. Since the disc 73 is in contact with the circular ring 5, the circular ring 5 drives the disc 73 to move up, thereby driving the connecting shaft 72 to drive the weeding knife 8 to move up. Thus, the distance between the weeding knife 8 and the slope surface of the soil slope becomes larger and larger, thereby effectively avoiding the weeding knife 8 from being stuck at the top of the soil slope. When the auxiliary wheels 3 close to the moving direction of the cart 1 also pass the highest point of the soil slope, the group of auxiliary wheels 3 close to the moving direction of the cart 1 drive the several movable rods 2 connected thereto to slowly move down, but the group of auxiliary wheels 3 away from the moving direction of the cart 1 slowly approach the highest point of the soil slope, thereby driving the several movable rods 2 connected to the group of auxiliary wheels 3 away from the moving direction of the cart 1 to slowly move up. Thus, the weeding knife 8 always keeps a safe distance from the slope surface of the soil slope, so that the weeding knife 8 does not contact the soil slope, further avoiding the weeding knife 8 from being stuck at the top of the soil slope and avoiding the weeding knife 8 from being damaged.

[0033] When the cart 1 moves to a position of a pit, the movable rods 2 slowly move down, thereby driving the weeding knife 8 to slowly move down, so that the weeding knife 8 can remove the weeds in the pit, thereby improving the weeding effect.

[0034] Further, the connecting shaft 72 is provided with a plurality of guide strips 721, and the rotating shaft 71 is provided with a plurality of guide grooves in which the guide strips 721 are clamped.

[0035] In actual application, the guide strips 721 and the guide grooves can ensure that the rotating shaft 71 drives the connecting shaft 72 to rotate, and at the same time, the guide strips 721 and the guide grooves can ensure that the connecting shaft 72 keeps rotating when moving up and down. Thus, the weeding knife 8 can rotate to weed when moving up and down, thereby ensuring the weeding effect.

[0036] Further, the disc 73 is embedded with a plurality of movable balls 74 on the surface in contact with the circular ring 5.

[0037] In actual application, the balls 74 are embedded in the bottom of the disc 73 and roll. Thus, when the circular ring 5 drives the connecting shaft 72 to move up and down, it does not affect the rotation of the connecting shaft 72 and the rotation of the weeding knife 8 to weed, so that the weeding knife 8 can smoothly rotate to weed when moving up and down.

[0038] Further, the weeding knife 8 is provided with a fixed shaft 81 which is sleeved on the connecting shaft 72.

[0039] In one case of the embodiment, the fixed shaft 81 can be threadedly connected with the connecting shaft 72.

[0040] In practical application, the height of the weeding knife 8 can be adjusted by rotating the fixing shaft 81 in the connecting shaft 72, so that weeds of different heights can be removed, and the practicability is improved.

[0041] As shown in Figure 3 and Figure 4 , the top of the cart 1 is provided with two sealed boxes 10, and the top of each set of movable rods 2 is provided with a push plate 9, which is located in the sealed box 10 and sealed with the inner wall of the sealed box 10. The sealed box 10 is connected with an air inlet pipe 12, the other end of the air inlet pipe 12 is connected with an air bag 11, the air bag 11 is connected with an air outlet pipe 14, the other end of the air outlet pipe 14 is connected with a drain pipe 15, the other end of the drain pipe 15 is connected with a water spraying pipe 16, and the water spraying pipe 16 is directed towards the weeding knife 8.

[0042] In practical application, the upward movement of the movable rod 2 will drive the push plate 9 to move up, and the push plate 9 will squeeze the air in the sealed box 10 when moving up. The air enters the air bag 11 through the air inlet pipe 12, thereby inflating the air bag 11. Finally, the gas is sprayed out through the air outlet pipe 14, the drain pipe 15 and the water spraying pipe 16. The sprayed gas is directed towards the weeding knife 8. In this way, the weeds remaining on the weeding knife 8 can be blown off the weeding knife 8, avoiding the influence of the remaining weeds on the normal weeding of the weeding knife 8. At the same time, the weeds on the surface of the weeding knife 8 can be blown clean when the weeding is finished, avoiding the weeds sticking to the blade of the weeding knife 8 and increasing the resistance when the weeding knife 8 weeds later, thereby reducing the weeding efficiency. At the same time, since the cut weeds contain water, if the cut weeds stick to the weeding knife 8 and are not cleaned in time, the weeding knife 8 may rust, thereby reducing the weeding efficiency of the weeding knife 8. Cleaning the weeds from the weeding knife 8 in time can ensure the weeding efficiency of the weeding knife 8.

[0043] Further, the air inlet pipe 12 and the air outlet pipe 14 are both provided with a one-way valve 13.

[0044] In practical application, the one-way valve 13 on the air inlet pipe 12 is arranged to only blow air into the air bag 11, and the gas in the air bag 11 cannot enter the sealed box 10 through the one-way valve 13. The one-way valve 13 on the air outlet pipe 14 is arranged to only blow air into the drain pipe 15, and the gas cannot enter the air bag 11 through the drain pipe 15 and the one-way valve 13. In this way, it is ensured that the compressed gas in the air bag 11 will only be sprayed from the water spraying pipe 16 towards the weeding knife 8, thereby effectively converting the kinetic energy of the push plate 9.

[0045] Further, a plurality of water tanks 17 are arranged on the cart 1, and one end of the drain pipe 15 is connected with the water tank 17.

[0046] In one case of the embodiment, a water pump is installed in the water tank 17, and the water pump is connected with the drain pipe 15.

[0047] In actual application, the water pump in the water tank 17 draws water to the drain pipe 15, and finally the water is sprayed out through the water spraying pipe 16, so that the weeding knife 8 can be cleaned. In the water tank 17, the weeding medicine can be stored, and after being sprayed out through the water spraying pipe 16, the medicine can be sprayed to weeds, so that the growth of weeds is effectively inhibited, and the weeds and the pasture compete for soil nutrients, water, light and other resources are effectively avoided. In addition, the compressed gas sprayed out by the air bag 11 shares the drain pipe 15 and the water spraying pipe 16 with water or medicine, so that the material of the device is reduced, and at the same time, the compressed gas sprayed out by the air bag 11 can clean the residues of water or medicine in the drain pipe 15 and the water spraying pipe 16, so that the water or medicine slowly corrodes the drain pipe 15 and the water spraying pipe 16 is effectively avoided.

[0048] Working principle: in use, push the cart 1, adjust the weeding knife 8 to the appropriate height, start the driving part 6 to make the weeding knife 8 rotate and weed, when the cart 1 moves to a position with a large slope, after the wheels at the front end of the cart 1 pass over the highest point of the slope, the group of auxiliary wheels 3 close to the moving direction of the cart 1 drive the plurality of movable rods 2 connected thereto to slowly move upward, when the plurality of movable rods 2 move upward, the connecting rod 4 drives the circular ring 5 to move upward, because the disc 73 is in contact with the circular ring 5, the circular ring 5 drives the disc 73 to move upward, so that the connecting shaft 72 drives the weeding knife 8 to move upward, so that the distance between the weeding knife 8 and the slope surface becomes larger and larger, so that the weeding knife 8 is effectively prevented from being stuck on the top of the slope, when the auxiliary wheels 3 close to the moving direction of the cart 1 also pass over the highest point of the slope, the group of auxiliary wheels 3 close to the moving direction of the cart 1 drive the plurality of movable rods 2 connected thereto to slowly move downward, but the group of auxiliary wheels 3 away from the moving direction of the cart 1 also slowly approach the highest point of the slope, so that the group of auxiliary wheels 3 away from the moving direction of the cart 1 drive the plurality of movable rods 2 connected thereto to slowly move upward, so that the weeding knife 8 always maintains a safe distance from the slope surface, so that the weeding knife 8 does not contact the slope, further avoiding the weeding knife 8 from being stuck on the top of the slope and avoiding the weeding knife 8 from being damaged.
