[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0038] The present invention provides a grassland ecological restoration and plant protection device, such as Figures 1 to 6 As shown, the cart body includes a push frame 1, a placement table 2, a water tank 3, a spraying component and a rotating component; the placement table 2 is horizontally installed between the two push frames 1, and the two push frames 1 are parallel to each other. The water tank 3 is placed on the top of the placement table 2. A screw hole 4 is provided at the center of the inner bottom surface of the water tank 3, and the spraying component is screwed into the screw hole 4. The rotating component causes the spraying component to rotate inside the screw hole 4, and the rotating spraying component sprays the liquid fertilizer inside the water tank 3. When the cart body is moved forward by the push frame 1, the moving cart body moves on the grass using the rotating component, and the rotating component causes the spraying component to move up inside the screw hole 4. At this time, the liquid fertilizer inside the water tank 3 is sprayed around the cart body through the rotating spraying component, which facilitates the cart body to complete the spraying of liquid fertilizer during the forward movement, and facilitates the liquid fertilizer to repair the grass and ensure the plant protection effect of the grass.

[0039] The spraying component includes an inner frame 5, a threaded portion 6, a spraying pipe 7, a water trough 8 and an elastic component that limits the spraying pipe 7; the outer circumferential surface of the inner frame 5 is surrounded by a threaded portion 6, the threaded portion 6 is spirally engaged with the screw hole 4, and multiple spraying pipes 7 are surrounded by the outer circumferential surface of the inner frame 5. The multiple water troughs 8 inside the inner frame 5 correspond one-to-one to the multiple spraying pipes 7. The rotating inner frame 5 moves up on the screw hole 4 using the threaded portion 6, and the upward moving inner frame 5 makes the top opening of the water trough 8 connected to the water tank 3. When the cart body moves forward on the grass, the forward-moving cart body uses the rotating part to make the inner frame 5 of the spraying part rotate clockwise. The clockwise-rotating inner frame 5 uses the threaded portion 6 inside the screw hole 4. The rotating threaded portion 6 makes the inner frame 5 move up inside the screw hole 4 until the threaded portion 6 moves up to the top of the screw hole 4. The upward-moving inner frame 5 makes the top opening of the water trough 8 move to the inside of the water tank 3. When the inner frame 5 continues to rotate inside the screw hole 4, the liquid fertilizer inside the water tank 3 enters the inside of the spraying pipe 7 through the water trough 8, and is rotated and sprayed out through the outer opening of the spraying pipe 7. The rotating spraying pipe 7 is used to make the liquid fertilizer sprayed around the cart body in a rotational manner, thereby ensuring the uniformity of liquid fertilizer spraying.

[0040] The inner frame 5 is rotated clockwise to squeeze the elastic component during the upward movement, and the elastic component makes the bottom of the threaded portion 6 always correspond to the top of the screw hole 4. After spraying is completed, the cart body is pulled in the opposite direction, and the cart body uses the rotating component to make the inner frame 5 rotate counterclockwise. The counterclockwise rotating inner frame 5 is driven by the elastic force of the elastic component to make the threaded portion 6 rotate in the opposite direction inside the screw hole 4. The inner frame 5 moves downward inside the screw hole 4 until the threaded portion 6 is at the bottom of the screw hole 4. At this time, the top opening of the water trough 8 enters the interior of the screw hole 4, preventing the liquid fertilizer inside the water tank 3 from flowing out directly through the spraying component, thereby avoiding waste of liquid fertilizer.

[0041] exist Figures 4 to 6 In the embodiment, the elastic component includes a sleeve frame 9, a vertical rod 10, and a spring clip 11; multiple sleeve frames 9 correspond one-to-one to multiple spray pipes 7. The sleeve frame 9 is sleeved on the surface of the spray pipe 7, and the vertical rod 10 is fixed to the top surface of the sleeve frame 9. The top surface of the spray pipe 7 is connected to the inner top surface of the sleeve frame 9 by the spring clip 11. The bottom surface of the water tank 3 is provided with a ring frame 12. The elastic force of the spring clip 11 causes the top of the vertical rod 10 to be inserted into the bottom of the ring frame 12. The top of the outer side of the inner frame 5 is provided with a ring edge. The elastic force of the spring clip 11 causes the bottom surface of the ring edge to fit the inner bottom surface of the water tank 3, preventing liquid fertilizer from flowing out through the gap between the inner frame 5 and the screw hole 4.

[0042] When the inner frame 5 rotates clockwise, the clockwise rotating threaded portion 6 moves upward inside the screw hole 4, and the upwardly moving inner frame 5 drives the spray pipe 7 to move upward inside the sleeve frame 9. The upwardly moving spray pipe 7 cooperates with the sleeve frame 9 to squeeze the spring piece 11 until the threaded portion 6 is at the top of the screw hole 4. The elastic force of the spring piece 11 makes the bottom of the threaded portion 6 always correspond to the spiral of the top of the screw hole 4; when the inner frame 5 rotates counterclockwise, the elastic force of the spring piece 11 is applied to the inner frame 5 through the spray pipe 7 to move upward. At this time, the elastic force of the spring piece 11 causes the threaded portion 6 to rotate and move downward inside the screw hole 4 until the threaded portion 6 is at the bottom of the screw hole 4, and the spray pipe 7 is at the bottom inside the sleeve frame 9.

[0043] When the inner frame 5 rotates, the rotating inner frame 5 uses the sleeve frame 9 to drive the vertical rod 10 to rotate at the bottom of the ring frame 12. Multiple vertical rods 10 cooperate with multiple sleeve frames 9, and the elastic force of the spring piece 11 makes the inner frame 5 rotate smoothly inside the screw hole 4.

[0044] exist Figure 1 and Figure 3 In the figure, the rotating parts include a roller 13, a rotating rod 14, a main gear 15, a slave gear 16 and a square rod 17; the two rollers 13 are arranged opposite to each other, and the two rollers 13 are fixedly connected by the rotating rod 14, the bottom end of the push frame 1 is sleeved on the surface of the rotating rod 14, and a main gear 15 is fixed in the middle of the rotating rod 14, and the slave gear 16 is engaged with the main gear 15, the main gear 15 is arranged vertically, and the slave gear 16 is arranged horizontally. The bottom end of the square rod 17 is connected to the top surface of the slave gear 16, and the top end of the square rod 17 is inserted into the bottom inner side of the inner frame 5. The bottom surface of the inner frame 5 is provided with a square groove corresponding to the square rod 17. The roller 13 rolling on the ground uses the main gear 15 on the surface of the rotating rod 14 to drive the slave gear 16 to rotate, and the rotating slave gear 16 uses the square rod 17 to make the inner frame 5 rotate inside the screw hole 4. When the cart body moves forward on the grass, the roller 13 rolls on the grass, and the roller 13 uses the rotating rod 14 to make the main gear 15 rotate counterclockwise. The counterclockwise rotating main gear 15 drives the horizontal slave gear 16 to rotate clockwise. The clockwise rotating slave gear 16 uses the square rod 17 to make the inner frame 5 rotate clockwise inside the screw hole 4. The clockwise rotating inner frame 5 uses the square groove to move up on the surface of the square rod 17.

[0045] When the cart body is pulled backward on the grass, the roller 13 uses the rotating rod 14 to make the main gear 15 rotate clockwise. The clockwise rotating main gear 15 drives the horizontal slave gear 16 to rotate counterclockwise. The counterclockwise rotating slave gear 16 uses the square rod 17 to make the inner frame 5 rotate counterclockwise inside the screw hole 4. The counterclockwise rotating inner frame 5 moves downward on the surface of the square rod 17 using the square groove.

[0046] The rotating component also includes a bottom rod 18, the bottom end of which is sleeved on the surface of the rotating rod 14, and the top end of the bottom rod 18 is inserted into the inner part of the slave gear 16. The rotating slave gear 16 rotates on the top end of the bottom rod 18. The top end of the square and round rod 17 is connected to a plurality of elastic bars 19, and the top ends of the elastic bars 19 are in contact with the inner top surface of the square and round groove. After the water tank 3 is placed on the top of the placement table 2, the water tank 3 uses the inner frame 5 of the spray component to vertically set the square and round rod 17. The vertically set square and round rod 17 uses the slave gear 16 to vertically set the bottom rod 18. Since the bottom end of the bottom rod 18 is sleeved on the surface of the rotating rod 14, the rotating slave gear 16 rotates on the top end of the bottom rod 18, thereby providing power for the rotation of the inner frame 5.

[0047] After the inner frame 5 moves downward so that the threaded portion 6 is at the bottom of the screw hole 4, the inner frame 5 uses the square-circular groove to squeeze the multiple elastic bars 19 at the top of the square-circular rod 17. The elastic force of the multiple elastic bars 19 makes the top of the threaded portion 6 correspond to the spiral of the screw hole 4. At this time, the inner frame 5 that continues to rotate counterclockwise will not move downward inside the screw hole 4, which facilitates the reverse movement of the cart body to drive the water tank 3 to move, so that the liquid fertilizer remains inside the water tank 3, avoiding the outflow of liquid fertilizer due to the movement of the cart body, resulting in waste of liquid fertilizer.

[0048] exist Figure 1 、 Figure 3 、 Figure 7 and Figure 8 In the embodiment, the push frame 1 is configured as a hollow structure, with a cross bar 20 provided at the top of the two push frames 1, a push rod 21 fixed at the end of the cross bar 20, the push rod 21 being inserted into the top of the push frame 1, a push strip 22 being provided inside the push frame 1, the bottom ends of the two push strips 22 being fixedly connected by a connecting rod 23, a toothed ring 24 being sleeved on the surface of the connecting rod 23, and a sliding groove corresponding to the connecting rod 23 being provided on the surface of the push frame 1. When the cross bar 20 is pushed forward, the forward-moving cross bar 20 drives the push rod 21 to move forward inside the push frame 1, the forward-moving push rod 21 drives the push strip 22 to move, and the moving push strip 22 drives the toothed ring 24 to approach the main gear 15 by means of the connecting rod 23, until the toothed ring 24 is engaged with the main gear 15, and then the main gear 15 rotating counterclockwise causes the toothed ring 24 to rotate clockwise on the surface of the connecting rod 23.

[0049] When the push rod 21 is pulled backward by the cross bar 20 , the backward-moving push rod 21 pulls the connecting rod 23 and the gear ring 24 away from the main gear 15 by the push bar 22 .

[0050] A baffle 25 is connected between the two push frames 1. The baffle 25 is located at the bottom of the water tank 3 and is tilted to the side of the rotating component. The surface of the baffle 25 is provided with multiple drainage grooves, and the gear ring 24 is located at the bottom of the baffle 25. When the forward-moving cart body uses the spraying component to spray liquid fertilizer, the liquid fertilizer sprayed by the rotation will also be sprayed on the surface of the tilted baffle 25 during the spraying process. The baffle 25 blocks the liquid fertilizer and prevents the rotating liquid fertilizer from being sprayed on the farmer's body, thereby protecting the farmer's body.

[0051] The liquid fertilizer blocked by the baffle 25 moves downward through the drainage trough, and the liquid fertilizer that moves downward drips onto the surface of the clockwise rotating gear ring 24. The clockwise rotating gear ring 24 is used to break up the dripping liquid fertilizer, ensuring that the liquid fertilizer is evenly dispersed around the cart body and the liquid fertilizer is sprayed evenly.

[0052] The present invention also provides a grassland ecological restoration and plant protection method, referring to Figures 1 to 8 As shown, the method uses the above-mentioned grassland ecological restoration and plant protection device, including the following steps:

[0053] S1. Pour liquid fertilizer into the water tank 3, and the pushing frame 1 drives the water tank 3 to move on the grass using the rotating part; S2. During the movement, the rotating part causes the inner frame 5 to rotate inside the screw hole 4 using the threaded portion 6, and the rotating inner frame 5 moves up on the screw hole 4 using the threaded portion 6. The upwardly moved inner frame 5 causes the top opening of the water trough 8 to be connected with the water tank 3, and the rotating spraying part sprays the liquid fertilizer inside the water tank 3 out; S3. The pushing frame 1 pulls the rotating part to move in the opposite direction, and the reversely rotating inner frame 5 moves down inside the screw hole 4 using the threaded portion 6, so that the top opening of the water trough 8 enters the screw hole 4, preventing the liquid fertilizer inside the water tank 3 from flowing out directly through the spraying pipe 7; S4. The cart body moves on the grass, and the liquid fertilizer is rotated and sprayed out by the spraying part, and liquid fertilizer can be added to the water tank 3 during the spraying process, and the liquid fertilizer can comprehensively repair the grass.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
