DETAILED DESCRIPTION

[0037] 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.

[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 placing table 2, a water tank 3, a spraying component and a rotating component; the placing table 2 is horizontally installed between two push frames 1, and the two push frames 1 are arranged side by side. The water tank 3 is placed on the top of the placing table 2, and 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 makes the spraying component 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 by the rotating component, and the rotating component makes the spraying component move up inside the screw hole 4. At this time, the liquid fertilizer inside the water tank 3 is sprayed around the cart body by the spraying component, which is convenient for the cart body to complete the spraying of liquid fertilizer during the forward movement, so that the liquid fertilizer can 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 inner frame 5 is surrounded by a threaded portion 6 on the outer side of the circumference, the threaded portion 6 is spirally matched with the screw hole 4, a plurality of spraying pipes 7 are surrounded by the outer side of the circumference of the inner frame 5, a plurality of water troughs 8 inside the inner frame 5 correspond one by one to a plurality of spraying pipes 7, the rotating inner frame 5 moves up on the screw hole 4 using the threaded portion 6, and the upwardly moved inner frame 5 makes the top opening of the water trough 8 communicate with 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, and the clockwise-rotating inner frame 5 uses the threaded portion 6 inside the screw hole 4, and 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, and 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 spray pipe 7 through the water trough 8, and is rotated and sprayed out through the outer opening of the spray pipe 7. The rotating spray pipe 7 is used to make the liquid fertilizer sprayed around the cart body in a rotational manner to ensure the uniformity of the 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, and 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 screw hole 4, preventing the liquid fertilizer inside the water tank 3 from directly flowing out through the spraying component, thereby avoiding the 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 sheet 11; a plurality of sleeve frames 9 correspond to a plurality of spray pipes 7 one by one, the sleeve frame 9 is sleeved on the surface of the spray pipe 7, the vertical rod 10 is fixed on the top surface of the sleeve frame 9, and the top surface of the spray pipe 7 is connected to the inner top surface of the sleeve frame 9 by the spring sheet 11, and the bottom surface of the water tank 3 is provided with a ring frame 12, and the elastic force of the spring sheet 11 makes the top of the vertical rod 10 plugged into the bottom of the ring frame 12. A ring edge is provided on the top of the outer side surface of the inner frame 5, and the elastic force of the spring sheet 11 makes the bottom surface of the ring edge fit with the inner bottom surface of the water tank 3 to prevent the 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 makes the threaded portion 6 rotate and move downward inside the screw hole 4. After the threaded portion 6 is at the bottom of the screw hole 4, the spray pipe 7 is at the bottom of the inner side of 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 sheet 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 the main gear 15 is fixed in the middle of the rotating rod 14, the slave gear 16 is meshed with the main gear 15, the main gear 15 is arranged vertically, 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, the top end of the square rod 17 is inserted into the bottom inner side of the inner frame 5, and 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, and 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, and the counterclockwise rotating inner frame 5 moves down 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 the bottom rod 18 is sleeved on the surface of the rotating rod 14, the top end of the bottom rod 18 is inserted into the inner part of the slave gear 16, and the rotating slave gear 16 rotates at the top end of the bottom rod 18. A plurality of elastic bars 19 are connected to the top end of the square and round rod 17, and the top end of the elastic bars 19 is 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 placing table 2, the water tank 3 uses the inner frame 5 of the spraying component to make the square and round rod 17 vertically arranged, and the vertically arranged square and round rod 17 uses the slave gear 16 to make the bottom rod 18 vertically arranged. 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 at 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 cart body that moves in the opposite direction 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 set as a hollow structure, and a cross bar 20 is set at the top of the two push frames 1, and a push rod 21 is fixed at the end of the cross bar 20. The push rod 21 is inserted at the top of the push frame 1, and a push strip 22 is set inside the push frame 1. The bottom ends of the two push strips 22 are fixedly connected by a connecting rod 23. A toothed ring 24 is sleeved on the surface of the connecting rod 23, and a sliding groove corresponding to the connecting rod 23 is set 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, and the forward-moving push rod 21 drives the push strip 22 to move. The moving push strip 22 drives the toothed ring 24 to approach the main gear 15 by using the connecting rod 23, until the toothed ring 24 is meshed with the main gear 15, and 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 push rod 21 that moves backward 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 at the bottom of the water tank 3 and is tilted on one side of the rotating component. A plurality of drainage grooves are arranged on the surface of the baffle 25, and the gear ring 24 is at the bottom of the baffle 25. When the forward-moving cart body sprays liquid fertilizer using the spraying component, the liquid fertilizer sprayed by rotation will also be sprayed on the surface of the inclined baffle 25 during the spraying process. The baffle 25 is used to block the liquid fertilizer to prevent the liquid fertilizer sprayed by rotation 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 groove, and the liquid fertilizer that moves downward drips on 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 plant protection device, including the following steps:

[0053] S1. Pour the liquid fertilizer into the water tank 3, and the push frame 1 drives the water tank 3 to move on the grass by using the rotating part; S2. During the movement, the rotating part makes the inner frame 5 rotate inside the screw hole 4 by using the threaded part 6, and the rotating inner frame 5 moves up in the screw hole 4 by using the threaded part 6, and the upwardly moved inner frame 5 makes the top opening of the water trough 8 communicate with the water tank 3, and the rotating spraying part sprays the liquid fertilizer inside the water tank 3 out; S3. The push 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 by using the threaded part 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 using the spraying part, and liquid fertilizer can be added to the inside of 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 them.
