[0025] 2. The present invention separates the first bending plate and the second bending plate of the bending frame from each other through the reaction force of the soil on the bending frame, and uses the moving first bending plate and second bending plate to push the soil apart. The diffusion component expands the inner cavity inside the soil through multiple bending frames, and the mist nutrients sprayed from the output port of the injection nozzle fills the entire inner cavity, ensuring sufficient contact between the soil and the nutrients.

[0026] 3. The present invention rotates the collar on the surface of the handle, and the collar uses the pull rod on the connecting strip to pull the collar plate upward. After the upwardly moved collar plate drives the clamping frame away from the triangular column, the reaction force of the soil on the drill bit causes the multiple bending frames to separate from each other. At this time, the injection nozzle on the surface of the injection frame is on the top surface of the soil, which is convenient for the mist nutrients sprayed from the output port of the injection nozzle to repair the soil surface.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0036] The present invention provides a soil restoration device for grassland ecology, such as Figures 1 to 5As shown, it includes a bracket 1, an injection component for nutrient injection is installed at the bottom of the bracket 1, and a storage cylinder 3 is connected to the top of the injection component by a connecting pipe 2. Nutrients for soil remediation are filled inside the storage cylinder 3, and the storage cylinder 3 is placed on the front side of the bracket 1; the injection component includes an injection frame 4, an injection nozzle 5, and a diffusion component that limits the injection nozzle 5 to inject nutrients; the bottom end of the connecting pipe 2 is connected to the injection frame 4, and a plurality of injection nozzles 5 are arranged on the circumferential outer side of the injection frame 4, and the diffusion component includes a side frame 6, a bending frame, an inclined frame, and a side frame 7. Rod 7 and an elastic component that limits the inclined rod 7; a vertical tube 8 is connected to the bottom of the bracket 1, the injection frame 4 is at the bottom end of the vertical tube 8, and the connecting pipe 2 is inside the vertical tube 8, a plurality of side frames 6 are arranged in a ring at the bottom end of the vertical tube 8, the injection nozzle 5 is between two adjacent side frames 6, and both outer sides of the side frames 6 are provided with inclined grooves 9. The bottom of the outer side surface of the circumference of the inclined rod 7 is connected to the bending frame by a connecting rod 10. The plurality of bending frames correspond to the plurality of injection nozzles 5 one by one, and the bending frames cooperate to block the output port of the injection nozzle 5, and the plurality of bending frames cooperate to form a drill bit. The nutrients required for soil remediation are filled into the storage cylinder 3, and the nutrients in the storage cylinder 3 enter the injection frame 4 through the connecting pipe 2. The bottom of the drill bit is inserted into the soil. At this time, the vertical pipe 8 drives the injection frame 4 to move downward, and the reaction force of the soil on the bending frame causes the bending frame and the injection frame 4 to move in an offset manner. The top of the bending frame squeezes the elastic component, and the side frame 6 moves downward on the surface of the connecting rod 10 through the inclined groove 9. Under the sliding cooperation of the inclined groove 9 and the connecting rod 10, multiple bending frames are separated from each other. At this time, the bending frame is away from the output port of the injection nozzle 5. At this time, the nutrients inside the injection frame 4 are sprayed out through the injection nozzle 5, and the sprayed nutrients are combined with the soil, and the nutrients are used to repair the soil.

[0037] exist Figure 1 and Figure 2 In the embodiment, the injection frame 4 has a built-in water pump, and the support 1 has a built-in controller. A handle 11 is connected to the top of the support 1, and a control button 12 is provided at the bottom of the handle 11. The water pump is electrically connected to the controller, and the control button 12 is electrically connected to the controller. When the control button 12 is pressed, the controller starts the water pump, and the water pump sprays the nutrients in the injection frame 4 through multiple injection nozzles 5. When the bending frame moves away from the injection nozzle 5, the soil is pushed away from the injection nozzle 5 to prevent the soil from blocking the output port of the injection nozzle 5, thereby ensuring the continuous spraying effect of the injection nozzle 5.

[0038] exist Figures 2 to 5In the figure, the bending frame includes a first bending plate 13 and a second bending plate 14, the first bending plate 13 and the second bending plate 14 of the bending frame are fitted together, and the fitting between the first bending plate 13 and the second bending plate 14 corresponds to the output port of the injection nozzle 5, and two connecting rods 10 are arranged at the bottom of the outer side surface of the circumference of the inclined rod 7, and the bottom of the inclined rod 7 is connected to the inner side surface of the first bending plate 13 by the connecting rod 10, and the bottom of the inclined rod 7 is connected to the second bending plate 14 by the connecting rod 10. The inner side of the side frame 6 is provided with a slot corresponding to the inclined rod 7, the inner side of the inclined groove 9 is connected to the slot, the distance between the top end of the inclined rod 7 and the injection frame 4 is greater than the distance between the bottom end of the inclined rod 7 and the injection frame 4, the movable bending frame uses the connecting rod 10 to move the inclined rod 7 inside the slot, and a spring piece 15 is provided inside the inclined groove 9, the top end of the spring piece 15 is connected to the top of the inner side of the inclined groove 9, and the bottom end of the spring piece 15 is in contact with the surface of the connecting rod 10, and a circular plate 16 is provided at the top end of the inclined rod 7. The elastic force of the spring piece 15 makes the bottom surface of the circular plate 16 fit with the top surface of the side frame 6. By pressing, multiple bending frames are made to enter the soil. When the reaction force of the soil on the bending frames limits the bending frames, the vertical pipe 8 that continues to move downward causes the side frame 6 to move downward on the surface of the inclined rod 7. The side frame 6 slides on the surface of the inclined rod 7 through the slot. The inclined rod 7 is tilted. The downward-moving side frame 6 uses the slot to push the inclined rod 7 away from the injection frame 4. At this time, the inclined rod 7 uses the connecting rod 10 to drive the first bending plate 13 and the second bending plate 14 away from the injection frame 4. Since the connecting rod 10 is horizontally inserted in the inclined groove 9, the two connecting rods 10 corresponding to the inner side of the bending frame are separated from each other, and the side frame 6 cooperates with the connecting rod 10 to squeeze the spring sheet 15 during the downward movement. At this time, the first bending plate 13 and the second bending plate 14 of the bending frame are separated from each other, and the moving first bending plate 13 and the second bending plate 14 are used to push the soil apart. The diffusion component expands the inner cavity inside the soil through multiple bending frames, and the mist nutrients sprayed from the output port of the injection nozzle 5 fills the entire inner cavity to ensure sufficient contact between the soil and the nutrients.

[0039] When the diffusion component is pulled out from the inner cavity of the soil using the handle 11, the upward side frame 6 moves on the surface of the connecting rod 10 using the inclined groove 9, and the elastic force of the spring sheet 15 limits the bending frame through the connecting rod 10. The elastic force of the spring sheet 15 makes the two connecting rods 10 corresponding to the inner side of the bending frame approach each other. At this time, the first bending plate 13 and the second bending plate 14 of the bending frame approach each other until the bending plate blocks the output port of the injection nozzle 5 correspondingly, and then the drill bit is pulled out from the soil through the handle 11.

[0040] exist Figures 2 to 6In the embodiment, the elastic component includes a triangular column 17, a clamping frame 18, a sleeve plate 19 and a retaining ring 20; the sleeve plate 19 is horizontally sleeved on the surface of the vertical tube 8, the retaining ring 20 is fixed on the surface of the vertical tube 8, the retaining ring 20 is at the top of the sleeve plate 19, the bottom surface of the retaining ring 20 is connected to the top of the sleeve plate 19 by a spring 21, the spring 21 is sleeved on the surface of the vertical tube 8, a plurality of clamping frames 18 are installed on the bottom surface of the sleeve plate 19 in a circular arrangement, a plurality of triangular columns 17 correspond to a plurality of inclined rods 7 one by one, the bottom end of the triangular column 17 is connected to the top surface of the circular plate 16, and the top end of the triangular column 17 is clamped on the outer side of the clamping frame 18. The cross-sectional structure of the triangular column 17 is set as an isosceles triangle, the outer opening of the clamping frame 18 is set as a clamping slot, and the top end of the triangular column 17 is plugged into the outer side of the clamping frame 18 through the clamping slot. When the drill bit is pressed into the soil, the elastic force of the spring 21 acts on the top of the circular plate 16 through the sleeve plate 19 and the triangular column 17. When the reaction force of the soil on the bending frame is smaller than the elastic force of the spring 21, the drill bit can enter the soil under pressure.

[0041] When the bottom surface of the sleeve 19 is attached to the soil surface, the downward vertical tube 8 and the sleeve 19 are dislocated and moved, and the downward vertical tube 8 and the retaining ring 20 squeeze the spring 21. At this time, the elastic force of the spring 15 facilitates the vertical tube 8 to use the side frame 6 to drive the inclined rod 7 and the triangular column 17 to move downward synchronously, until the top of the triangular column 17 is pulled out from the bottom of the card slot, the card frame 18 The restriction on the triangular column 17 disappears, and the reaction force of the soil on the bending frame prevents the drill bit from continuing to move downward. The downward vertical tube 8 drives multiple side frames 6 to move downward inside the drill bit. Since the inclined rod 7 is tilted and inserted into the slot, the inclined inclined rod 7 uses the connecting rod 10 to keep the bending frame away from the injection frame 4, and the bending frames that are away from each other diffuse the inner cavity of the soil, which is convenient for the mist nutrients sprayed from the output port of the injection nozzle 5 to fully contact the soil and ensure the soil repair effect.

[0042] When the drill bit is pulled out by using the handle 11, the elastic force of the spring sheet 15 acts on the connecting rod 10, and the elastic force of the spring sheet 15 facilitates the bending frame to approach the injection frame 4 until the inner side of the bending frame fits against the output port of the injection nozzle 5. The elastic force of the spring 21 makes the bottom surface of the sleeve plate 19 always fit against the soil surface, and the upward vertical pipe 8 moves up at the center of the sleeve plate 19. The vertical pipe 8 drives the triangular column 17 to move up by using the side frame 6, and the top of the upward triangular column 17 is inserted into the slot until the top of the triangular column 17 fits against the bottom surface of the sleeve plate 19. At this time, the upward vertical pipe 8 pulls the sleeve plate 19 away from the soil through the triangular column 17, and the drill bit gradually moves out from the soil under the action of the pulling force.

[0043] exist Figure 1 and Figure 7In the embodiment, both ends of the handle 11 are sleeved with collars 22, and the two collars 22 are connected by a connecting strip, and the outer side of the connecting strip is connected to the top surface of the sleeve plate 19 by a pull strip 23. When the drill bit is inserted into the top surface of the soil, the collar 22 on the surface of the handle 11 is rotated, and the collar 22 uses the pull strip 23 on the connecting strip to pull the sleeve plate 19 upward. After the upward sleeve plate 19 drives the clamping frame 18 away from the triangular column 17, the reaction force of the soil on the drill bit causes the multiple bending frames to separate from each other. At this time, the injection nozzle 5 on the surface of the injection frame 4 is on the top surface of the soil, which is convenient for the mist nutrients sprayed from the output port of the injection nozzle 5 to repair the soil surface.

[0044] The present invention also provides a method for soil restoration for grassland ecology, referring to Figures 1 to 7 As shown, the method uses the above-mentioned grassland ecological soil remediation device, including the following steps:

[0045] S1. Fill the nutrients needed for soil remediation into the storage tube 3. The nutrients in the storage tube 3 enter the injection frame 4 through the connecting tube 2. S2. Use the handle 11 to drive the bracket 1 and the injection component to move, and insert the bottom of the drill bit into the soil. At this time, the vertical tube 8 drives the injection frame 4 to move downward. The reaction force of the soil on the bending frame causes the bending frame and the injection frame 4 to move out of position. The top of the bending frame squeezes the elastic component, and the side frame 6 moves downward on the surface of the connecting rod 10 through the inclined groove 9. Under the sliding cooperation between the inclined groove 9 and the connecting rod 10, more The bending frames are separated from each other, and at this time the bending frames are away from the output port of the injection nozzle 5; S3, pressing the control button 12, the controller makes the water pump work, the water pump sprays the nutrients inside the injection frame 4 through multiple injection nozzles 5, and the soil is repaired by the nutrients; S4, releasing the control button 12, using the handle 11 to pull the injection component out of the soil, the elastic component moves the bending frame down until the bending frame blocks the output port of the injection nozzle 5, so that the handle 11 can be used to make the injection component repair the next soil.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
