[0016] Synergistic effect of the soil-turning component and the spraying component: The setting of the soil-turning component enables the spraying of the medicament through the spray pipe first during the spraying process, then turning the soil with the turning plow, and finally supplementing the spraying through the spray pipe on the other side, improving the absorption effect of the soil on the medicament and thus enhancing the soil remediation effect.

[0017] Innovation of the spraying component: On the one hand, through the reciprocating telescoping of the first electric cylinder, the front and back adjustment of the spray pipe can be realized, expanding the spraying range; on the other hand, while the spray pipe is adjusted front and back, under the action of the auxiliary groove, the mounting arm and the spray pipe move up and down reciprocally. When realizing the up and down reciprocating movement of the spray pipe, no separate electric component is required for driving, and the structure is reasonable.

[0018] Innovation of the first mixing component and the liquid pump inlet pipe: On the one hand, driving the first mixing plate to move left and right by the second motor can realize the mixing of the liquid medicine in the liquid storage tank, ensuring the spraying quality; on the other hand, when the first mixing plate moves, it can drive the liquid suction faucet to move. By the movement of the liquid suction faucet, the accumulation of residues at the liquid suction faucet can be avoided, preventing the liquid suction faucet from being blocked, and the structure is flexible.

[0019] Innovation of the second mixing component and the third mixing component: On the one hand, the second mixing component drives the impeller to rotate through the third motor to remix the liquid medicine, further improving the uniformity of the liquid medicine; on the other hand, the third mixing component uses the rotation of the impeller to push the second mixing plate to move up and down reciprocally to realize the remixing of the liquid medicine, ensuring the high uniformity of the liquid medicine. The third mixing component does not require a separate electric component for driving, saving costs, and when the third motor is damaged, the second mixing plate can still be driven to move up and down for mixing through the mounting arm, and the structure is strong.

[0020] The protection component improves the spraying quality: The protection component drives the protective cover to expand outward through the extension of the third electric cylinder, effectively avoiding the influence of strong wind weather on the spraying and ensuring the spraying quality.

The two first electric cylinders 202 can drive the spray pipe 208 to move back and forth, and at this time, the spraying range can be expanded, improving the spraying efficiency; the spraying uniformity can be improved by the linearly arrayed spray heads 209.

[0047] Among them, an auxiliary block 206 is welded on the top surface of the vehicle body 1. The auxiliary block 206 is a rectangular block-shaped structure.

The description of this positional relationship can ensure that spraying is carried out first, then plowing, and then spraying again; a spraying component 2 is also installed at the right side position of the top end face of the vehicle body 1. Through the settings of the tilling plow 803 and the right spraying component 2, during the spraying process, first spraying is carried out through the left spray pipe 208, then turning is carried out through the tilling plow 803 after spraying, and then spraying is carried out through the right spray pipe 208. At this time, the effect of the soil absorbing the medicament is improved, and thus the soil remediation effect is improved.

[0049] Among them, a clamping groove 103 is provided on each of the left end face and the right end face of the liquid storage tank 101. The two clamping grooves 103 are both rectangular groove-shaped structures. The two clamping grooves 103 are clamped on the two auxiliary blocks 206. At this time, the liquid storage tank 101 is in a limited state. Through the two auxiliary blocks 206, the height adjustment of the spray pipe 208 can be realized in cooperation with the mounting arm 205, and the liquid storage tank 101 can be limited and fixed by being clamped with the clamping groove 103. There is no need to separately use a screw to fix the liquid storage tank 101, and the clamping type fixing structure is more convenient and fast when disassembling and assembling the liquid storage tank 101.

A second motor 402 is fixed to the left end face of the inner wall of the liquid storage tank 101. A threaded rod 403 is fixed to the output shaft of the second motor 402. The threaded rod 403 is threadedly connected to the first mixing plate 401. Driven by the second motor 402 and the threaded rod 403, the left and right movement of the first mixing plate 401 can be realized. At this time, the mixing of the liquid in the liquid storage tank 101 can be realized. By mixing the liquid in the liquid storage tank 101, the uniformity of the liquid medicine can be ensured, and the soil remediation quality is ensured.

The two sliding arms 703 both slide on the cover plate 102. One end of the lower part of each sliding arm 703 is welded with a counterweight 704. The bottom end surface of the second mixing plate 702 contacts the impeller 602. When the impeller 602 rotates, it can push the second mixing plate 702 to move up and down reciprocally. Through the up - and - down reciprocating movement of the second mixing plate 702, the mixing uniformity of the liquid medicine in the liquid storage tank 101 can be improved again.

[0054] Among them, the two counterweights 704 are both rectangular block structures. The bottom end surfaces of the two counterweights 704 respectively contact the top end surfaces of the two mounting arms 205.

The two worms 302 are respectively engaged with the two worm gears 301; a first motor 303 is fixed on each mounting arm 205, and the output shafts of the two first motors 303 are respectively fixed on the two worms 302. Through the drive of the first motor 303, the worm 302, and the worm gear 301, the rotation of the spray pipe 208 can be realized, and thus the angle adjustment of the nozzle 209 can be realized. By adjusting the angle of the nozzle 209, the adjustability during spraying of the device can be improved, and the practicability is high.

[0058] Working principle: Drive the vehicle body 1 to move and start two liquid medicine pumps 501. At this time, spraying starts at the two spray pipes 208. Control the two first electric cylinders 202 to reciprocate telescopically. The two first electric cylinders 202 drive the spray pipes 208 to move back and forth to achieve extended spraying. At the same time, under the action of the auxiliary groove 207, the mounting arm 205 and the spray pipes 208 move up and down reciprocally for spraying; during the spraying process, first spray through the left spray pipe 208, then turn over with the turning plow 803 after spraying, and then spray through the right spray pipe 208; control the second motor 402 to rotate. Driven by the second motor 402 and the threaded rod 403, the left and right movement of the first mixing plate 401 can be realized to mix the liquid medicine; at the same time, drive the third motor 603 to rotate. The third motor 603 drives the rotating shaft 601 and the impeller 602 to rotate for re-mixing; at the same time, during the rotation of the impeller 602, the second mixing plate 702 can be pushed to move up and down reciprocally for re-mixing; when the third motor 603 is damaged and cannot rotate, then when the mounting arm 205 moves up and down reciprocally, the second mixing plate 702 can also be driven to move up and down reciprocally for mixing; when adjusting the angle of the nozzle 209, just drive the two first motors 303 to rotate. The rotation of the spray pipe 208 can be realized under the meshing transmission of the worm 302 and the worm gear 301, and thus the angle adjustment of the nozzle 209 is realized; when spraying in strong wind weather, control the four third electric cylinders 902 to extend. The four third electric cylinders 902 drive the four protective covers 903 to expand outwards.
