The drug storage mechanism is arranged on the traveling mechanism and is used to store and transport liquid drugs; the telescopic mechanism is arranged on the traveling mechanism and connected to the soil-breaking rod, which can make the soil-breaking rod reciprocate in the vertical direction; the soil-breaking rod is connected to the drug storage mechanism and has a drug spraying port and a nozzle switch, and the soil-breaking rod can spray the drug liquid when the nozzle switch is turned on; the drill bit assembly is rotatably mounted on the bottom end of the soil-breaking rod; and the control unit is electrically connected to the drug storage mechanism, the telescopic mechanism, and the soil-breaking rod respectively. This utility model effectively solves the problems of poor soil integrity and poor aesthetics caused by the existing reclamation and turning-over repair methods. However, in actual use, the repair liquid can only be applied from a single vertical direction, resulting in uneven distribution of the repair liquid in the soil, affecting the repair effect. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a soil in-situ repair device, which aims to improve the problem in the existing technology that the repair liquid can only be applied from a single vertical direction, resulting in uneven distribution of the repair liquid in the soil and affecting the repair effect.

[0015] An armrest is provided on the left side of the top of the base plate, a seat is provided on the right side of the armrest, and the bottom of the seat is fixedly connected to the top of the base plate.

[0016] Through the above technical solution: the armrest provides the operator with a handle to control the moving direction of the device, which is convenient for operation during the movement process.

[0035] Refer to the attached Figure 1 , Attachment Figure 2 and attached Figure 6 The cleaning mechanism 2 includes an electric telescopic rod 201, the outer wall of the electric telescopic rod 201 is fixedly connected to the inner side of the bottom of the base plate 1, one end of the electric telescopic rod 201 is fixedly connected to a fixing plate 203, the bottom of the fixing plate 203 is fixedly connected to a connecting column 204, the bottom of the connecting column 204 is installed with a mounting plate 205, and the bottom of the mounting plate 205 is fixedly connected to a dust cleaning shovel 202; a front wheel 27 is provided on the left side of the bottom of the base plate 1, and a rear wheel 26 is provided on the right side of the bottom of the base plate 1; an armrest 24 is provided on the left side of the top of the base plate 1, and a seat 25 is provided on the right side of the armrest 24, and the bottom of the seat 25 is fixedly connected to the top of the base plate 1, which is convenient for the operator to work for a long time;

[0036] Specifically, the electric telescopic rod 201 can accurately control the height of the cleaning shovel 202. When there is debris or garbage in the soil, the electric telescopic rod 201 is started to drive the fixed plate 203, the connecting column 204 and the mounting plate 205 to move the cleaning shovel 202 downward to contact the soil surface, which can efficiently clean the debris in the soil and create good conditions for subsequent in-situ soil remediation.

[0037] Refer to the attached Figure 1 and attached Figure 2 The top of the bottom plate 1 is fixedly connected to a water pump 22, one end of the water pump 22 is connected to a water tank 21, and the other end of the water pump 22 is connected to a water pipe 23, forming an efficient liquid supply system. The top of the bottom plate 1 is fixedly connected to a side plate 3, which is used to place objects on the bottom plate 1 and remove them; the outer wall of the side plate 3 is fixedly connected to a controller 28, and the controller 28 is electrically connected to the servo motor 8 and the electric telescopic rod 201 respectively;

The presence of the controller 28 allows the operator to centrally control multiple key components in one location without having to operate each component separately, greatly improving the convenience of operation.

[0039] Working principle: First, move the device to a suitable position. The support column 4 is fixed to the top right side of the base plate 1, providing a stable support base for the entire device. Then, through the rotation and coordination of the mechanical arm 1 5 and the mechanical arm 2 6, the position and angle of the fixed column 7 can be adjusted. At this time, the servo motor 8 is started. The output end of the servo motor 8 drives the shaft 1 9 to rotate, and the gear 10 on the outer wall of the shaft 1 9 rotates accordingly. Since the gear 10 is meshed with the gear 2 11, the gear 2 11 also starts to rotate, and the gear 2 11 drives the shaft 2 12 to rotate, and the shaft 2 12 rotates. When the soil is slurry-proofed, the rotating shaft 3 13 at both ends and the cylinder 14 fixedly connected to the outer wall of the rotating shaft 3 13 also rotate together, and the multiple liquid storage columns 15 inside the cylinder 14 and the hollow metal plate 17 connected to the outer wall of the liquid storage column 15 rotate synchronously in the soil. During the rotation process, the repair liquid stored in the liquid storage column 15 can enter the hollow metal plate 17 through the connecting hole 16. The multiple holes 18 on the top of the outer wall of the hollow metal plate 17 can allow the repair liquid to slowly seep out and contact with the soil, thereby realizing in-situ repair of the soil. When it is necessary to add repair liquid, it can be added by pulling the pull rod. The hand 20 pulls the sealing plug 19 out of the liquid storage column 15, inserts the water pipe 23 into the liquid storage column 15, starts the water pump 22 to suck the repair liquid from the water tank 21, and the front wheel 27 is set on the left side of the bottom of the bottom plate 1, and the rear wheel 26 is set on the right side of the bottom, which together support the entire device to move on the ground. The operator can control the moving direction of the device through the handrail 24 on the left side of the top of the bottom plate 1. When there is a lot of garbage in the soil that needs to be cleaned, the electric telescopic rod 201 is started, the electric telescopic rod 201 extends, and the fixed plate 203 fixed at one end moves downward. The bottom of the fixed plate 203 is fixedly connected to the connecting column 204, and the connecting column 204 also moves downward. The bottom of the connecting column 204 is installed with a mounting plate 205, and the mounting plate 205 drives the cleaning shovel 202 fixedly connected to its bottom to move downward and contact the soil surface. Then, the operator controls the device to move to the left. During the movement of the device, the garbage is collected in the cleaning shovel 202. When the garbage is collected to a certain extent or the cleaning work is completed, the garbage can be processed as needed. After cleaning the garbage, the device continues to perform in-situ soil remediation work.
