The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0048] See also Figure 1 , Figure 2 as well as Figure 3 The present embodiment provides a spraying device for preventing and controlling invasive alien plants, including a medicine storage box 10, a first drive assembly 20, a spraying assembly 30, a medicine delivery pipeline 40, a second drive assembly 50 and a piston assembly 60. The bottom of the medicine storage box 10 is provided with a plurality of casters 101, the spraying assembly 30 is hingedly arranged on the outer wall of the medicine storage box 10, and the first drive assembly 20 is arranged below the spraying assembly 30. When the medicine storage box 10 moves along the ground, the first drive assembly 20 is used to drive the medicine delivery assembly 30 to move horizontally. The piston assembly 60 is installed inside the medicine storage box 10, one end of the medicine delivery pipeline 40 is connected to the piston assembly 60, and the other end is connected to the medicine spraying assembly 30. The second driving assembly 50 is arranged above the medicine spraying assembly 30. When the medicine spraying assembly 30 reciprocates horizontally, the second driving assembly 50 is used to drive the piston assembly 60 to move, so as to transport the medicine liquid inside the medicine storage box 10 to the medicine spraying assembly 30 via the medicine delivery pipeline 40 and spray it onto the ground by the medicine spraying assembly 30.

[0049] When it is necessary to spray liquid medicine to prevent and control invasive alien plants, the corresponding liquid medicine can be loaded into the medicine storage box 10, and then the medicine storage box 10 moves along the ground through a plurality of casters 101 at the bottom thereof. During the walking process of the medicine storage box 10, the first driving assembly 20 drives the spraying assembly 30 to swing back and forth horizontally on the outer wall of the medicine storage box 10, and at the same time, the second driving assembly 50 is used to drive the piston assembly 60 to move. When the piston assembly 60 moves, the liquid medicine inside the medicine storage box 10 is transported to the spraying assembly 30 through the medicine delivery pipeline 40, and the liquid medicine is then sprayed to the ground by the spraying assembly 30, thereby killing the alien plants. When the spraying assembly 30 sprays the liquid medicine to the ground, since the spraying assembly 30 is in a horizontal reciprocating swinging state on the outer wall of the medicine storage box 10, the spraying range of the liquid medicine can be increased, thereby improving the killing effect of the alien plants.

[0050] See also Figure 1 , Figure 4 as well as Figure 5 In one embodiment, the medicine spraying assembly 30 includes a support rod 301, a nozzle 302 and a nozzle 303. One end of the support rod 301 is hingedly connected to the outer wall of the medicine storage box 10, and the other end extends horizontally in a direction away from the medicine storage box 10. The nozzle 302 is fixedly installed at the bottom of the support rod 301 and distributed along the length direction of the support rod 301. One end of the nozzle 302 is connected to the piston assembly 60 through the medicine delivery pipeline 40. The nozzle 303 is provided with a plurality of groups, and a plurality of the nozzles 303 are fixedly arranged at the bottom of the nozzle 302 and distributed at intervals along the length direction of the nozzle 302.

[0051] When the medicine storage box 10 moves along the ground, the first driving component 20 drives the support rod 301 to swing back and forth horizontally compared to the outer wall of the medicine storage box 10, thereby driving the nozzle 302 and the plurality of nozzles 303 to swing back and forth horizontally synchronously. At the same time, the second driving component 50 drives the piston component 60 to move inside the medicine storage box 10 to transport the medicine liquid inside the medicine storage box 10 to the inside of the nozzle 302 through the medicine delivery pipeline 40, and then sprayed out by the plurality of nozzles 303 at the bottom of the nozzle 302 and act on the ground to kill foreign plants. Since the nozzle 302 and the plurality of nozzles 303 are in a horizontal reciprocating swinging state, the medicine liquid sprayed by the plurality of nozzles 303 can cover a larger ground area, thereby improving the killing effect of foreign plants.

[0052] See also Figure 1 as well as Figure 4In one embodiment, a notch 3011 is provided on the support rod 301, a support plate 105 is fixedly provided on the side wall of the medicine storage box 10, and the first driving assembly 20 includes a roller 201, a shaft 202, a driving bevel gear 203, a driven bevel gear 204, a rotating rod 206, a rotating shaft 207 and a rotating disk 208, the roller 201 is arranged at the lower side of the medicine storage box 10, the end of the shaft 202 is fixedly connected to the roller 201, the driving bevel gear 203 is fixedly provided on the shaft 202, and the driven bevel gear The wheel 204 is arranged above the driving bevel gear 203 and meshes with the driving bevel gear 203, the rotating rod 206 is fixedly arranged on the upper part of the driven bevel gear 204, the rotating shaft 207 vertically penetrates the support plate 105 and rotates with the support plate 105, the lower end of the rotating shaft 207 is connected to the rotating rod 206, and the upper end is connected to the turntable 208, and a shift rod 209 is fixedly arranged at an eccentric position on the upper surface of the turntable 208, and the shift rod 209 extends to the inside of the slot 3011 and movably cooperates with the support rod 301.

[0053] When the medicine storage box 10 moves along the ground, the support plate 105 can drive the roller 201 to roll along the ground. When the roller 201 rolls, it drives the shaft 202 and the driving bevel gear 203 to rotate. When the driving bevel gear 203 rotates, it drives the rotating rod 206, the rotating shaft 207 and the turntable 208 to rotate through the meshing action with the driven bevel gear 204. When the turntable 208 rotates, it drives the lever 209 to move in a circle. When the lever 209 moves in a circle, the cooperation between the lever 209 and the slot 3011 drives the support rod 301 to swing back and forth horizontally compared to the outer wall of the medicine storage box 10, thereby driving the nozzle 302 and a plurality of nozzles 303 to swing back and forth synchronously horizontally, so that the liquid medicine sprayed through the nozzle 303 can cover a large area of ​​the ground, so as to increase the spraying range of the liquid medicine and improve the killing effect of foreign plants.

[0054] See also Figure 1 as well as Figure 6 In one embodiment, a bracket plate 205 is rotatably provided on the outside of the shaft rod 202, and an ear plate 2051 is fixedly provided on the side wall of the bracket plate 205. A guide rod 210 is vertically penetrated on the ear plate 2051, and the ear plate 2051 is movably matched with the guide rod 210. The upper end of the guide rod 210 is fixedly connected to the support plate 105, and the upper part of the ear plate 2051 is also connected to the support plate 105 through a first elastic member 211. The first elastic member 211 is used to provide elastic support for the ear plate 2051. A socket is opened inside the rotating shaft 207, and the upper end of the rotating rod 206 extends into the socket and is telescopically matched with the rotating shaft 207. A second elastic member 212 is provided in the socket, and the second elastic member 212 is used to provide elastic support for the rotating rod 206.

[0055] The first elastic member 211 elastically supports the ear plate 2051, so that the bracket plate 205 can obtain downward elastic pressure, and the elastic pressure is transmitted to the shaft rod 202 and the roller 201, so that the roller 201 is in close contact with the ground. When the medicine storage box 10 moves along the ground, the roller 201 can adaptively roll along the ground, and when encountering an uneven ground, the roller 201 can move up and down accordingly, thereby driving the shaft rod 202, the bracket plate 205 and the ear plate 2051 to move up and down synchronously, and the ear plate 2051 adaptively slides up and down along the outside of the guide rod 210, and the first elastic member 211 adaptively expands and contracts, while the shaft rod 202 moves up and down. When moving, the rotating rod 206 can be driven to move up and down adaptively along the inside of the socket through the resistance between the driving bevel gear 203 and the driven bevel gear 204, and then adaptively telescopically move compared to the rotating shaft 207. In this way, when the roller 201, the shaft 202 and the driving bevel gear 203 move up and down, the driven bevel gear 204 can move up and down with the driving bevel gear 203, so that the driving bevel gear 203 and the driven bevel gear 204 always maintain a meshing posture, thereby ensuring that the rotating rod 206, the rotating shaft 207 and the turntable 208 can always maintain a rotating state when encountering uneven ground, thereby always providing swinging power to the support rod 301.

[0056] In one embodiment, the rotating rod 206 and the socket are both square structures that fit each other. When the roller 201 rolls along the ground and drives the shaft 202 and the driving bevel gear 203 to rotate, the driving bevel gear 203 and the driven bevel gear 204 are meshed and transmitted to drive the rotating rod 206 to rotate. Since the rotating rod 206 and the socket are both square structures that fit each other, the rotating rod 206 can drive the rotating shaft 207 to rotate when it rotates, and then drive the turntable 208 to rotate, so that the lever 209 can move the support rod 301 to drive the support rod 301 to swing back and forth horizontally compared to the outer wall of the medicine storage box 10.

[0057] In one embodiment, the first elastic member 211 and the second elastic member 212 may be springs or metal springs, which are not limited herein.

The end of the connecting rod 501 away from the U-shaped rod 502 is hingedly connected to the support rod 301. The medicine delivery pipeline 40 includes a second hose 402 and a second hard tube 404. One end of the second hard tube 404 is fixedly connected to the side wall of the piston cylinder 601 and communicated with the inner cavity of the piston cylinder 601, and the other end is connected to the second hose 402. The end of the second hose 402 away from the second hard tube 404 extends from the through hole 104 to the outside of the medicine storage box 10 and communicates with the nozzle 302. A one-way valve (not shown in the figure) is arranged inside the second hard tube 404.

[0059] For ease of understanding, select Figure 1 Describe the principle, such as Figure 1As shown, initially, the support rod 301 maintains a middle position on the outer wall of the medicine storage box 10 and is perpendicular to the outer wall of the medicine storage box 10. At this time, the connecting rod 501 maintains a vertical state. When the medicine storage box 10 walks along the ground so that the roller 201 drives the turntable 208 to rotate, the lever 209 drives the support rod 301 to make the support rod 301 swing to the left side of the medicine storage box 10. At this time, the connecting rod 501 is pulled and rotated to an inclined state, and then the U-shaped rod 502 is pulled to make the U-shaped rod 502 move downward. When the U-shaped rod 502 moves downward, it drives the piston block 603 to move downward along the inside of the piston cylinder 601. At this time, the one-way The valve is in an open state, and the one-way valve in the second hard tube 404 is in a closed state. The piston block 603 moves downward to extract the liquid in the medicine storage box 10 into the piston cylinder 601 through the first medicine inlet pipe 602. When the support rod 301 swings to the left side of the medicine storage box 10 to the maximum amplitude, the lever 209 moves the support rod 301 to make the support rod 301 swing to the middle position of the medicine storage box 10. At this time, the connecting rod 501 is pushed and drives the U-shaped rod 502 to move upward. The U-shaped rod 502 drives the piston block 603 to move upward along the inside of the piston cylinder 601. At this time, the one-way valve in the first medicine inlet pipe 602 is closed, and the liquid in the second hard tube 404 is pumped into the piston cylinder 601. The one-way valve is opened, and the piston block 603 moves upward to pressurize the liquid medicine drawn into the piston cylinder 601 into the nozzle 302 through the second hard tube 404 and the second hose 402, and then sprayed to the ground by a plurality of nozzles 303. After the support rod 301 passes through the middle position of the medicine storage box 10 and swings to the right side of the medicine storage box 10, the connecting rod 501 is pulled again and drives the U-shaped rod 502 to move downward again. The U-shaped rod 502 drives the piston block 603 to move downward along the piston cylinder 601 again, so as to draw the liquid medicine inside the medicine storage box 10 into the piston cylinder 601 through the first medicine inlet pipe 602 again. When the support rod 301 After swinging to the right side of the medicine storage box 10 to the maximum amplitude, the lever 209 pushes the support rod 301 so that the support rod 301 swings to the middle position of the medicine storage box 10. At this time, the connecting rod 501 is pushed again and drives the U-shaped rod 502 to move upward again. The U-shaped rod 502 drives the piston block 603 to move upward along the inside of the piston cylinder 601 again, so that the liquid medicine in the piston cylinder 601 is pressed again through the second hard tube 404 and the second soft tube 402 to the inside of the nozzle 302, and then sprayed to the ground through a plurality of nozzles 303 again. Such a reciprocating cycle can realize the automatic pressure delivery of the liquid medicine in the medicine storage box 10 and the automatic spraying of the liquid medicine.

The connection position of the first hard tube 403 and the piston cylinder 601 is located below the piston block 603, and the connection position of the second hard tube 404 and the piston cylinder 601 is located above the piston block 603.

[0061] When the support rod 301 swings toward the middle position of the medicine storage box 10 and then drives the U-shaped rod 502 to move upward through the connecting rod 501, the U-shaped rod 502 drives the piston block 603 to move upward along the inside of the piston cylinder 601. At this time, the piston block 603 extracts the liquid inside the medicine storage box 10 through the second medicine inlet pipe 604 to the lower area inside the piston cylinder 601. At the same time, the piston block 603 presses the liquid in the upper area inside the piston cylinder 601 through the second hard pipe 404 and the second hose 402 to the inside of the nozzle 302, and then sprays it to the ground through a plurality of nozzles 303; when the support rod 301 passes over the middle position of the medicine storage box 10, the connecting rod 501 is pulled and drives the U-shaped rod 502 to move downward, and the U-shaped rod 502 drives The piston block 603 moves downward along the inside of the piston cylinder 601.

[0063] The working principle of the present invention is as follows:

[0064] The medicine liquid for killing foreign plants is introduced into the medicine storage box 10 from the medicine adding port 103, and then the medicine storage box 10 moves along the ground with the help of the electric casters 101. When the medicine storage box 10 moves, it drives the roller 201 to roll along the ground, thereby driving the shaft rod 202 and the driving bevel gear 203 to rotate, and the meshing action of the driving bevel gear 203 and the driven bevel gear 204 drives the rotating rod 206, the rotating shaft 207 and the rotating disk 208 to rotate, and the rotating disk 208 drives the lever 209 at the upper eccentric position thereof to move in a circle. When the lever 209 moves in a circle, it drives the support rod 301 to swing back and forth horizontally compared with the outer wall of the medicine storage box 10 through the cooperation with the notch 3011. During the swinging process of the support rod 301, the connecting rod 501 is repeatedly pushed and pulled, thereby driving the U-shaped rod 502 to move up and down. When the piston block 603 moves downward, the medicine liquid in the medicine storage box 10 is drawn to the inner bottom of the piston cylinder 601 through the second medicine inlet pipe 604 when the piston block 603 moves upward, and on the other hand, the medicine liquid in the upper inner part of the piston cylinder 601 is pressed into the inside of the swinging nozzle 302 through the second hard tube 404 and the second hose 402, and then sprayed to the ground by the plurality of swinging nozzles 303; when the piston block 603 moves downward, the medicine liquid in the medicine storage box 10 is drawn to the inner upper part of the piston cylinder 601 through the first medicine inlet pipe 602 when the piston block 603 moves upward, and on the other hand, the medicine liquid in the lower inner part of the piston cylinder 601 is pressed into the inside of the swinging nozzle 302 through the first hard tube 403 and the first hose 401, and then sprayed to the ground by the plurality of swinging nozzles 303.

[0065] In the embodiment of the present invention, when it is necessary to spray liquid medicine to prevent and control invasive alien plants, the corresponding liquid medicine can be loaded into the medicine storage box 10, and then the medicine storage box 10 moves along the ground through a plurality of casters 101 at the bottom thereof. During the movement of the medicine storage box 10, the first driving assembly 20 drives the spraying assembly 30 to swing back and forth horizontally on the outer wall of the medicine storage box 10, and at the same time, the second driving assembly 50 is used to drive the piston assembly 60 to move. When the piston assembly 60 moves, the liquid medicine inside the medicine storage box 10 is transported to the spraying assembly 3 through the medicine delivery pipeline 40. 0, the liquid medicine is then sprayed onto the ground by the spray component 30, thereby killing the alien plants. When the spray component 30 sprays the liquid medicine onto the ground, since the spray component 30 is in a horizontal reciprocating swinging state on the outer wall of the medicine storage box 10, the spraying range of the liquid medicine can be increased, thereby improving the killing effect of the alien plants. Compared with the prior art, when spraying and killing alien plants, there is no need for excessive manual intervention, and the spraying range of the liquid medicine can be automatically increased, thereby improving the killing effect and efficiency of the alien plants.

[0066] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
