[0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. There are many reasons for soil pollution, such as industrial sludge, agricultural use of garbage, sewage irrigation, atmospheric pollutant deposition, large-scale use of mineral fertilizers and pesticides containing heavy metals, etc. Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or to convert toxic and harmful pollutants into harmless substances.

[0003] The existing patent with publication number CN113814265A discloses a soil pollution remediation and treatment device and method thereof, which belongs to the field of soil remediation technology; it includes a pusher head, a handle seat and a chassis, the handle seat is fixedly arranged at the upper end of the back of the pusher head, the chassis is fixedly arranged at the lower end of the back of the pusher head, and the handle seat is fixedly connected to the chassis; a soil shoveling groove is slotted in the middle of the lower end of the pusher head, a medicine box is fixedly connected to the inner side of the soil shoveling groove, a liquid storage tank is clamped in the medicine box, a tank plug is plugged at the upper end of the back of the liquid storage tank, a spray plate is fixedly connected to the left and right ends of the bottom of the medicine box, a liquid valve pipe is embedded on the side of the spray plate, and the liquid valve pipe is connected to the spray plate A nozzle is provided through the connection, a branch pipe is inserted at the upper end of the inner side of the liquid valve pipe, and the upper end of the branch pipe is communicated with the bottom of the liquid storage tank; an air bin is fixedly connected to the upper end of the reagent box, and the air bin is fixedly connected to the inner wall of the pusher head. The repair and treatment device can repair the soil through the synchronous breaking and spraying structure, which improves the repair effect and applicability of the device. In the device, the soil repair liquid can be sprayed on the surface of the broken soil through the nozzle, but this method not only causes the volatilization of the soil repair agent, but also can only be sprayed on the soil surface, and it is difficult to penetrate into the deeper soil, resulting in poor effect on soil pollution control.

[0004] The existing patent with publication number CN112718846B discloses a soil pollution control repair and treatment equipment, including a triangular support seat, a motion component is installed inside the triangular support seat, an output component is installed inside the triangular support seat directly below the motion component, the triangular support seat includes a top support plate and a triangular support frame fixedly connected to the bottom of the top support plate, a fixing groove is provided at the top of the top support plate, a first ear seat is fixedly connected to the top of the top support plate at a short side of the top support plate, a first rotating hole is provided on the first ear seat, and a second ear seat is fixedly connected to the wall surface of the short side of the first ear seat in the fixing groove. The present invention solves the problem that the existing soil pollution control equipment can only put the drug on the soil surface and the control effect is poor by providing a motion component to make the drill bit insert into the deep soil hole, and then output the drug to the drilled deep hole through the output component. This method can deliver the drug to the deep soil by drilling, but it is easy to cause the concentration of the soil repair agent sprayed in the part of the soil to be too high, and it is not easy to diffuse evenly, resulting in uneven mixing of the soil and the repair agent, affecting the effect of soil pollution control.

[0045] Step 3: In step 2, when the digging bucket 117 rotates to the bottom of the material discharge assembly, the first lever 118 abuts against the first push plate 107 and pushes the first tooth plate 105 to move rightward, driving the rotating gear 104 to rotate forward. At this time, the sieve plate 110 is driven to move by the rotating shaft 116 and the push rod 109, so that the soil remediation agent falls into the digging bucket 117 and mixes with the soil;

[0046] Step 4: In step 3, the digging bucket 117 continues to rotate, the first lever 118 is separated from the first push plate 107, and the second lever 119 is against the second push plate 108.

[0060] Working principle: The device can be fixedly connected to the lifting assembly on the common tractor models on the market through the connecting frame 113a, and the device can be driven to move forward and lift through the tractor and the lifting assembly. The soil remediation agent can be put into the storage box 113, wherein the soil remediation agent of the device can be a granular solid soil remediation agent to reduce the volatilization caused during the delivery process; when the device moves forward slowly and uniformly, the reduction motor 211 is started, and the reduction motor 211 drives the first gear 208 to rotate through the central shaft 202, and the first gear 208 drives the intermediate gear 209 to rotate, and the intermediate gear 209 drives the inner gear 210 to drive ... The straight cylinder 201 rotates, and the straight cylinder 201 drives the multiple digging buckets 117 to rotate. When the digging buckets 117 come into contact with the soil, the soil will be dug into the digging buckets 117. During this process, the central shaft 202 drives the large gear 204 to rotate, and the large gear 204 drives the small gear 205 to rotate rapidly. The small gear 205 drives the horizontal shaft 206 to rotate itself, thereby driving the second crushing blade 207 to rotate around the horizontal shaft 206. The soil can be crushed and mixed by the first crushing blade 117b and the second crushing blade 207. When the opening of the digging bucket 117 faces downward, the soil will automatically fall to the ground under the action of gravity.

[0061] Furthermore, when the digging bucket 117 rotates to the bottom of the material discharge assembly, the first lever 118 will first abut against the first push plate 107. As the digging bucket 117 rotates, the first lever 118 will push the first push plate 107 to move rightward, and the first push plate 107 will drive the first tooth plate 105 to move rightward. The first tooth plate 105 will drive the rotating gear 104 to rotate forward and make the second tooth plate 106 move leftward. The rotating gear 104 will drive the screen plate 110 to move through the rotating shaft 116 and the push rod 109. As the digging bucket 117 continues to rotate, the first lever 118 will separate from the first push plate 107. At this time, the second lever 119 will abut against the second push plate 108. The second lever 119 will drive the second push plate 108 to move rightward. 08 The second tooth plate 106 will drive the rotating gear 104 to rotate in the opposite direction and make the first tooth plate 105 move to the left for reset. The rotating gear 104 will drive the screen plate 110 to move in the opposite direction through the rotating shaft 116 and the push rod 109. Therefore, the rotation of the digging bucket 117 can drive the screen plate 110 to move left and right repeatedly. In the process of repeated movement of the screen plate 110, the soil remediation agent will fall into the digging bucket 117 through the discharge pipe 114. At this time, the soil in the digging bucket 117 is being crushed and stirred. Therefore, when the soil remediation agent falls into the digging bucket, it will be fully and evenly mixed with the soil, thereby improving the effect of soil pollution control.
