On the upper side of the front of the liquid medicine tank 1, the integrated controller 102 is installed by bolts. On the lower right part of the liquid medicine tank 1, the guard plate housing 2 is welded. The guard plate housing 2 will block sundries such as dust and sediment generated inside due to soil turning. On the front and back of the lower part of the guard plate housing 2, the straight roller group 201 is symmetrically installed by bolts. The straight roller group 201 will assist the movement of this device. On the left side of the bottom surface of the liquid medicine tank 1, the fixing frame 3 is welded.

Both driving wheels 4 are electrically connected to the integrated controller 102. The liquid medicine tank 1 is symmetrically connected to the connecting pipe 5 by bolts. On the two connecting pipes 5, the water pumps 6 are respectively installed by bolts. The water pumps 6 are electrically connected to the integrated controller 102. The other ends of the two connecting pipes 5 are slidably connected to the sprayer 7. The sprayer 7 is located directly below the liquid medicine tank 1. The water pump 6 will transfer the soil repair liquid in the liquid medicine tank 1 to the sprayer 7 through the connecting pipe 5, and then the sprayer 7 will spray the soil repair liquid on the soil. At the bottom of the guard plate housing 2, there is a soil turning component for turning the compacted soil.

[0028] When soil pollution repair work needs to be carried out, first inject the soil repair liquid into the liquid medicine tank 1 through the filling hole 101, then start the driving wheels 4 to rotate through the integrated controller 102. The driving wheels 4 will drive this device to move to the right, and the straight roller group 201 will assist in moving forward. Then start the two water pumps 6 through the integrated controller 102. The two water pumps 6 will extract the soil repair liquid in the liquid medicine tank 1 and then transport it to the sprayer 7 along the connecting pipe 5. The sprayer 7 will spray the soil repair liquid on the polluted soil.

[0029] Embodiment 2: On the basis of Embodiment 1, as Figure 1 、 Figure 2 and Figure 4 shown, the soil turning component includes a pulley group 801, a rotating rod 802 and a soil turner 803. On the mutually remote sides of the two driving wheels 4, the pulley groups 801 are respectively fixedly connected. The other ends of the two pulley groups 801 are fixedly connected to the rotating rod 802. On the rotating rod 802, the soil turners 803 are symmetrically fixedly installed in the front and back. Both soil turners 803 are located inside the guard plate housing 2. When the driving wheels 4 rotate, they will drive the soil turners 803 to turn the compacted soil through the pulley group 801.

[0030] As Figure 1 、 Figure 2 and Figure 5As shown, it further includes a dust exhaust component. The dust exhaust component includes a fixed plate 901, an exhaust fan 902, and a filter screen 903. The left side of the bottom surface of the guard plate housing 2 is welded with the fixed plate 901. A convex portion is provided in the middle of the right surface of the fixed plate 901. The convex portion on the fixed plate 901 will guide impurities such as dust and sediment. And the fixed plate 901 is located between the fixed frame 3 and the sprayer 7. Two exhaust fans 902 are symmetrically installed on the front and back of the fixed plate 901 by bolts. Both exhaust fans 902 are electrically connected to the integrated controller 102. Filter screens 903 are respectively installed on the right sides of the two exhaust fans 902 by bolts. Large pieces of dust, sediment and other impurities will be blocked by the filter screen 903.

[0031] As Figure 1 , Figure 2 , Figure 6 and Figure 7 shown, it further includes a uniform spraying mechanism. The uniform spraying mechanism includes a convex block 1001, a push rod 1002, a first return spring 1003, a connecting ring 1004, and a return spring 1006. Six convex blocks 1001 are respectively fixedly connected along the circumferences on the sides of the two driving wheels 4 close to each other. And the convex blocks 1001 on the two driving wheels 4 are arranged staggeredly. Push rods 1002 are symmetrically and slidably connected on the front and back of the fixed plate 901. When the convex blocks 1001 on the driving wheels 4 rotate, they will contact the push rods 1002 on the same side. The convex blocks 1001 on both sides will sequentially push the push rods 1002 to move to the right. First return springs 1003 are respectively fixed between the two push rods 1002 and the fixed plate 901. Connecting rings 1004 are symmetrically and fixedly connected on the front and back of the sprayer 7. Guide grooves 1005 are respectively opened on the top surfaces of the two connecting rings 1004. The other ends of the two push rods 1002 are respectively located in the guide grooves 1005 of the connecting rings 1004 on the same side and are slidably connected to the connecting rings 1004 on the same side. The push rods 1002 will push the guide grooves 1005 of the connecting rings 1004 to drive the sprayer 7 to move. Return springs 1006 are respectively fixed between the front end and the rear end of the sprayer 7 and the guard plate housing 2.

[0032] As Figure 1 , Figure 2 and Figure 8As shown, it further includes a cleaning mechanism. The cleaning mechanism includes a rack 1101, a one-way gear 1102, a reciprocating lead screw 1103, a guide rod 1104, and a scraper 1105. The top surfaces of the two ejector rods 1002 are respectively bolted with a rack 1101. The two racks 1101 are in sliding contact with the fixed plate 901. The front and rear of the right side of the fixed plate 901 are symmetrically welded with guide rods 1104. The front and rear of the right side of the fixed plate 901 are symmetrically rotatably connected with reciprocating lead screws 1103. The tops of the two reciprocating lead screws 1103 are respectively fixedly installed with one-way gears 1102. The two one-way gears 1102 rotate idly counterclockwise, and the two one-way gears 1102 mesh with the racks 1101 on the same side. Scrapers 1105 are respectively threaded on the two reciprocating lead screws 1103. When the reciprocating lead screw 1103 rotates, it will drive the scraper 1105 to move up and down reciprocally through the thread. The other end of the scraper 1105 is slidably connected to the guide rod 1104 on the same side, and the scraper 1105 is in sliding contact with the filter screen 903 on the same side. When the scraper 1105 moves up and down reciprocally, it will scrape off dust and other impurities on the filter screen 903.

[0033] As Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, it further includes a dust reduction mechanism. The dust reduction mechanism includes an arc-shaped top block 1201, a one-way conduit 1202, a spray pipe 1203, a slide rod 1204, a spherical top block 1205, a piston piece 1206, and a second return spring 1207. Three arc-shaped top blocks 1201 are respectively fixedly connected to the circumferences of the mutually remote sides of the two driving wheels 4. The lower part of the liquid medicine tank 1 is symmetrically bolted with one-way conduits 1202 at the front and rear. The other ends of the two one-way conduits 1202 are respectively fixedly connected to the spray pipes 1203. The soil repair liquid in the liquid medicine tank 1 will flow into the spray pipes 1203 through the one-way conduits 1202. Slide rods 1204 are respectively slidably connected to the mutually close sides of the two spray pipes 1203. The mutually close ends of the two slide rods 1204 are respectively fixedly installed with spherical top blocks 1205. When the driving wheel 4 rotates, the arc-shaped top block 1201 will contact the spherical top block 1205 on the same side. The mutually remote ends of the two slide rods 1204 are respectively fixedly connected to piston pieces 1206. The two piston pieces 1206 are respectively located in the spray pipes 1203 on the same side, and the piston piece 1206 is in sliding contact with the corresponding spray pipe 1203. The piston piece 1206 will squeeze the soil repair liquid in the spray pipe 1203 outwards. A second return spring 1207 is fixedly arranged between the two piston pieces 1206 and the corresponding spray pipes 1203.

[0034] As Figure 1 and Figure 2As shown, it further includes a plough 1301. The plough 1301 is welded inside the guard plate housing 2. As the device moves, the plough 1301 will break up the compacted soil. The plough 1301 is located between two soil-turning devices 803.

[0035] As Figure 2 shown, it further includes a soil moisture sensor 1302. The soil moisture sensor 1302 is installed on the left side of the top surface of the plough 1301 by bolts. The soil moisture sensor 1302 will monitor the soil moisture in real time during the movement of the device. The soil moisture sensor 1302 is electrically connected to the integrated controller 102.

[0036] While the driving wheel 4 rotates, the driving wheel 4 will drive the soil-turning device 803 on the rotating rod 802 to rotate synchronously through the pulley group 801. The soil-turning device 803 will turn over the compacted soil, so as to facilitate the faster infiltration of the soil repair liquid into the soil. The dust and sediment generated during this period will be blocked by the guard plate housing 2. Then, the exhaust fan 902 is started through the integrated controller 102. The two exhaust fans 902 will discharge the dust in the guard plate housing 2. The large-particle sediment and other impurities will be blocked by the filter screen 903. And the convex part in the middle of the fixing plate 901 will play a guiding role for the dust and sediment and other impurities, so that the dust in the guard plate housing 2 can always flow towards the exhaust fan 902. The soil repair liquid will also moisten the soil, thus playing a role in dust reduction.

[0037] As the driving wheel 4 rotates, the convex blocks 1001 on the two driving wheels 4 will successively push the ejector rods 1002 on the same side. The two ejector rods 1002 will move to the right successively. The elasticity of the first return spring 1003 will drive the corresponding ejector rod 1002 to move to the right and then return to the initial position. When the ejector rod 1002 moves to the right, the ejector rod 1002 will move along the guide groove 1005 on the connecting ring 1004, so as to push the corresponding connecting ring 1004 to move back and forth. The connecting ring 1004 will drive the sprayer 7 to move back and forth synchronously. The elasticity of the two return springs 1006 will cooperate to drive the sprayer 7 back to the initial position. In this way, the sprayer 7 will evenly spray the soil repair liquid on the turned-up soil.

[0038] During the process of the ejector rod 1002 moving to the right, the ejector rod 1002 will drive the rack 1101 to move to the right synchronously. The rack 1101 drives the reciprocating lead screw 1103 to rotate through the one-way gear 1102 meshed with it. The reciprocating lead screw 1103 will drive the scraper 1105 to move up and down reciprocally along the guide rod 1104 through the thread, so as to scrape and clean the filter screen 903, preventing the dust and sediment on the filter screen 903 from accumulating and blocking the exhaust fan 902.

[0039] When the driving wheel 4 drives the device to move, the arc-shaped top block 1201 on the driving wheel 4 will push the spherical top block 1205. The spherical top block 1205 will drive the piston piece 1206 to move into the spray pipe 1203 through the sliding rod 1204, and the second return spring 1207 will be stretched. The piston piece 1206 will squeeze the soil remediation liquid in the spray pipe 1203 and spray it out to both sides of the driving wheel 4. In this way, it can both reduce dust generated when the driving wheel 4 rotates and spray the soil remediation liquid outward. When the arc-shaped top block 1201 does not contact the spherical top block 1205, the second return spring 1207 resets and drives the spherical top block 1205, the sliding rod 1204, and the piston piece 1206 back to the initial position. The soil remediation liquid in the liquid medicine tank 1 will flow back into the spray pipe 1203 through the one-way conduit 1202.

[0040] During the movement of the device, the plough 1301 will break up the compacted soil to both sides, thus facilitating the turning by the tiller 803, so that the soil can be broken as much as possible and fully mixed with the soil remediation liquid. While the plough 1301 breaks up the soil, the broken soil will contact the soil humidity sensor 1302. The soil humidity sensor 1302 will transmit the humidity condition of the soil to the integrated controller 102 through an electrical signal, thereby realizing the real-time monitoring of the soil condition.

[0041] The above embodiments are only preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
