In order to control the desertification problem in karst mountainous areas and restore and improve the local ecological environment quality, afforestation, soil improvement and other means are generally adopted. In the process of planting, it is necessary to use equipment to dig pits in the planting area, and then spread seeds into the dug pits and backfill them. For example, the public document of an ecological planting device for controlling desertification in karst mountainous areas and its use method with publication number CN116034675A discloses such a planting device;

[0025] See also Figure 1 , Figure 3 and Figure 4A bracket is slidably provided on the mounting frame 5 (the bracket can move up and down on the mounting frame 5), a first driving member 6 (such as an electric, hydraulic, or pneumatic telescopic rod) is installed on the mounting frame 5, and a moving end of the first driving member 6 is connected to the bracket. A mounting box 7 is installed at the bottom of the bracket, and a moving plate 11 is slidably provided in the inner cavity of the mounting box 7. The moving direction of the moving plate 11 is the same as the moving direction of the mounting box 7 (the moving plate 11 can move up and down), and a rotating rod 8 is rotatably provided at the bottom of the moving plate 11. A through hole is provided at the bottom of the inner cavity of the mounting box 7, and the bottom end of the rotating rod 8 passes through the through hole and is connected to the drill bit 9. An elastic support member 13 (spring) is provided between the top of the inner cavity of the mounting box 7 and the top wall of the moving plate 11, and a driving component is provided in the inner cavity of the mounting box 7.

[0026] Among them, see Figure 3 and Figure 4 The driving assembly includes a second driving member 14 (motor), a driving gear 15 and a driven gear 12. The second driving member 14 is arranged on the mounting box 7, the driving gear 15 is arranged on the output end of the second driving member 14, the driven gear 12 is fixedly sleeved on the outer wall of the rotating rod 8, and the driven gear 12 is meshed with the driving gear 15, the axis of the driving gear 15 is parallel to the axis of the driven gear 12, and the driving gear 15 is meshed with the upper part of the driven gear 12 (such as Figure 4 As shown), when the rotating rod 8 moves up with the driven gear 12, the driven gear 12 continues to mesh with the driving gear 15.

[0027] It should be noted that a through hole is provided on the top of the vehicle body 1 so that the nozzle, the feed pipe and the drill bit 9 can pass through the vehicle body 1 .

[0028] A method for improving carbon sinks in karst desertification, the method steps are as follows:

[0029] First, after the vehicle body 1 is moved to the treatment area, the first driving member 6 and the second driving member 14 are controlled by the control device 4 to make the installation box 7 move down with the drill bit 9, and at the same time, the rotating rod 8 rotates with the drill bit 9 to open a planting hole in the treatment area. When opening the planting hole, when the drill bit 9 contacts the rock and the installation box 7 continues to move down with the drill bit 9, the rotating rod 8 moves toward the inside of the installation box 7 to prevent the drill bit 9 from moving down further, reduce the force generated by the hard contact between the drill bit 9 and the rock, protect the drill bit 9, and reduce the reaction force on the entire treatment device;

[0030] It should be noted that when there are rocks in the working area of ​​the drill bit 9, the first driving member 6 is controlled to move the drill bit 9 upward. The staff can choose to plant in the hole according to the depth of the hole that has been opened, or skip the hole and open a new hole.

[0031] Second, after the hole is opened, the first driving member 6 drives the drill bit 9 to move upward, and at the same time the second driving member 14 stops working, so that the drill bit 9 stops rotating, and then the seeds are sown into the hole through the sowing component 3 (open the valve to allow the seeds inside the storage box to fall into the planting hole through the feeding pipe under the action of gravity. The valve opening time is set. After the preset time is reached, the valve is closed to control the amount of seeds falling). After the hole is backfilled by the backfilling component 10, the backfilled hole area is irrigated by the watering component 2 (the pump works to spray the water in the storage tank to the backfilled hole area through the nozzle), and then the vehicle body 1 is moved to repeat the above operation.

[0032] In this embodiment, as a further optimized solution, please refer to Figure 3 , Figure 4 and Figure 5 A limit block 16 is installed on the top of the inner cavity of the installation box 7, and the limit block 16 is above the movable plate 11. A pressure sensor 17 is installed on the side wall of the limit block 16 facing the movable plate 11. The pressure sensor 17 is connected to the control device 4 (the pressure sensor 17 continuously transmits information to the control device 4), and the first drive member 6 and the second drive member 14 are both controlled to open and close by the control device 4; when the drill bit 9 contacts the rock and cannot continue to move downward, as the first drive member 6 continues to drive, the installation box 7 continues to move downward (the staff cannot timely understand that the drill bit 9 is blocked by the rock, so that the first drive member 6 continues to work), the length of the rotating rod 8 entering the interior of the installation box 7 increases, so that the movable plate 11 moves up until it presses the pressure sensor 17. After the control device 4 receives the information that the pressure sensor 17 is pressed, it controls the second drive member 14 and the first drive member 6 to stop working, automatically and timely prevents the drill bit 9 from continuing to move downward and rotate, and protects the treatment device.

[0033] In this embodiment, as a further optimized solution, please refer to Figure 4 and Figure 5, an opening is provided at the connection position between the installation box 7 and the elastic support member 13, and a support plate 21 is slidably provided in the inner cavity of the opening (the support plate 21 can move up and down), and the end of the elastic support member 13 away from the movable plate 11 is connected to the support plate 21, and a limiting groove 25 is provided on the outer wall of the support plate 21, and an installation groove is provided on the inner wall of the opening, and a limiting plug 22 is slidably provided in the inner cavity of the installation groove, and one end of the limiting plug 22 is inserted in the inner cavity of the limiting groove 25, which is used to limit the support plate 21 and prevent it from moving. An elastic member 23 (spring) is provided between the installation groove and the limiting plug 22, and a moving block 18 is slidably provided on the inner wall of the installation box 7, and the moving block 18 is located at the top of the movable plate 11, and the moving direction of the moving block 18 is the same as that of the movable plate 11. A placement groove is provided in the installation box 7, and a screw sleeve 20 is provided in the inner cavity of the placement groove. The movable plate 18 is provided with a connecting rope 24, and the movable block 18 is provided with a screw rod 19, and the end of the screw rod 19 away from the movable block 18 is inserted in the inner cavity of the screw sleeve 20; in the process of the movable plate 11 moving upward, the movable plate 11 will contact the movable block 18 and move it upward, so that the screw rod 19 moves into the inner cavity of the screw sleeve 20, so as to drive the screw sleeve 20 to rotate and wind the connecting rope 24 around the outer wall of the screw sleeve 20; when the connecting rope 24 is pulled, the limiting plug block 22 will be moved to the outside of the limiting groove 25 until the limiting plug block 22 moves out of the limiting groove 25 (at this time, the movable plate 11 just presses the pressure sensor 17 or is about to press the pressure sensor 17), and the restriction on the support plate 21 is released, so that the support plate 21 can move upward, so as to reduce the thrust of the elastic support member 13 on the movable plate 11, thereby further reducing the force applied to the drill bit 9 and protecting it.

[0034] In this embodiment, as a further optimized solution, please refer to Figure 3 and Figure 4 The rotating rod 8 includes a mounting rod 81 and a connecting rod 82. The mounting rod 81 is rotatably mounted on the bottom wall of the movable plate 11. The connecting rod 82 is connected to the drill bit 9. The connecting rod 82 is slidably sleeved on the outer wall of the mounting rod 81. A fixing part (bolt) is screwed on the outer wall of the connecting rod 82. The fastening end of the bolt contacts the outer wall of the mounting rod 81 to fix the connecting rod 82. Loosen the bolt and move the connecting rod 82 to adjust the length of the rotating rod 8 so that the distance between the drill bit 9 and the mounting box 7 can be adjusted as needed.

[0035] In this embodiment, as a further optimized solution, please refer to Figure 2 and Figure 6The backfill assembly 10 includes two mounting plates 101, two first push plates 102 and two second push plates 103. The two mounting plates 101 are both slidably arranged at the bottom of the vehicle body 1. A driving device (such as an electric telescopic rod) is provided on the vehicle body 1. The moving end of the driving device is connected to the mounting plate 101, and is used to drive the two mounting plates 101 to move closer to or away from each other. The two first push plates 102 are respectively arranged on the two mounting plates 101. A telescopic member (electric telescopic rod) is provided on the mounting plate 101. The moving end of the telescopic member is connected to the first push plates 102, and is used to drive the first push plates 102 to move up and down; a sliding groove is provided on one side wall of the two first push plates 102 that are close to each other, and the two second push plates 103 are respectively slidably arranged in the two sliding grooves, and a return spring is installed between the sliding groove and the second push plates 103. A pull spring is provided on the second push plates 103. Rope 104, one end of the pull rope 104 away from the second push plate 103 is arranged along the length direction of the slide groove, then passes through the first push plate 102 and is connected to the mounting plate 101; when the hole needs to be backfilled, the telescopic member drives the first push plate 102 to move downward, and then the driving device works to make the two mounting plates 101 move closer to each other, and move the first push plate 102 to push the soil into the hole. At the same time, when the first push plate 102 moves downward, the pull rope 104 will pull the second push plate 103 to move along the slide groove (at this time, the second push plate 103 moves closer to the drill bit 9) to push the soil, which is used to assist the first push plate 102 to complete the backfilling; after backfilling, the driving device resets the mounting plate 101 and drives the telescopic member to reset the first push plate 102 at the same time. At this time, the tension on the pull rope 104 disappears, and under the action of the reset spring, the second push plate 103 is reset.
