A power motor is fixedly installed on the body 1, and the power motor drives the driving wheels 11 to rotate, so that the body 1 can move on the ground.

[0033] The soil remediation device further includes a plowshare 12 and a sowing part. The plowshare 12 is fixedly connected to the bottom of the body 1. There is one or more plowshares 12. In the embodiment of the present application, the state where there is one plowshare 12 is taken as an example for description; one side of the plowshare 12 is a plowshare part 13, and the plowshare part 13 faces the advancing side of the body 1. When the body 1 advances, the plowshare 12 turns the soil on the ground to both sides of the plowshare part 13.

[0034] See Figure 1 And Figure 2, the spreading box 2 is fixedly installed at the bottom of the machine body 1. There are multiple spreading boxes 2 and they are arranged oppositely. The plowshare 12 is located between two relatively arranged spreading boxes 2, and the spreading box 2 is located on the side away from the plowshare part 13. The spreading box 2 is provided with a mixing cavity 21.

The driving motor 31 is fixedly installed on the mounting plate 231. The output shaft of the driving motor 31 is rotatably connected to the mounting plate 231. The output shaft of the driving motor 31 is fixedly connected and coaxially arranged with the rotating roller 23. When the driving motor 31 is started, it drives the rotating roller 23 to rotate. At this time, the stirring blades 232 stir the soil turned to both sides by the plowshare part 13 into the driving wheel 22 (the driving wheel 22 is marked in Figure 3 ).

[0037] See Figure 4 And Figure 5 , the spreading box 2 is provided with a first transmission assembly 4. When the rotating roller 23 (the rotating roller 23 is marked in Figure 1 ) rotates, the first transmission assembly 4 drives the driving wheel 22 to rotate.

[0038] See Figure 4 And Figure 6 , the first transmission assembly 4 includes a transmission gear ring 41, a transmission gear 42, and a transmission belt 43 (the transmission belt 43 is marked in Figure 1are marked), connecting shaft 44, first transmission shaft 45, transmission helical gear 46 and connecting helical gear 47; the connecting shaft 44 is rotatably connected inside the sowing box 2, the transmission gear 42 is fixedly connected to the outer peripheral side of the connecting shaft 44, and the transmission gear 42 is rotatably connected inside the sowing box 2.

The connecting helical gear 47 is fixedly connected to the outer peripheral side of the connecting shaft 44, the connecting helical gear 47 is rotatably connected inside the sowing box 2, and the connecting helical gear 47 meshes with the transmission helical gear 46.

[0040] When the linkage shaft 32 (the linkage shaft 32 is marked in Figure 1 drives the rotating roller 23 (the rotating roller 23 is marked in Figure 1 ) to rotate, the transmission belt 43 drives the first transmission shaft 45 to rotate. At this time, the connecting helical gear 47 and the transmission helical gear 46 cooperate to drive the connecting shaft 44 to rotate. At this time, the transmission gear 42 and the transmission gear ring 41 cooperate to drive the driving wheel 22 to rotate.

[0041] See Figure 2 and Figure 3 , on the inner peripheral side wall of the driving wheel 22, there are fixedly connected feeding sheets 221. There are multiple feeding sheets 221 and they are evenly spaced along the circumferential direction. The feeding sheets 221 extend obliquely downward from the feeding port 211 towards the discharging port 212. When the driving wheel 22 rotates and the feeding sheets 221 move from the bottom of the mixing chamber 21 towards the top of the mixing chamber 21, the soil inside the driving wheel 22 is driven by the feeding sheets 221 to move upward, and then the soil follows the feeding sheets 221 and is transmitted from the side of the feeding port 211 to the side of the discharging port 212.

[0042] Inside the sowing box 2, there is fixedly installed a mixing box 6. The side wall of the mixing box 6 far from the feeding port 211 seals the discharging port 212. The mixing box 6 is provided with a mixing groove 61, and the notch of the mixing groove 61 is located at the top of the mixing box 6. The vertical side wall of the mixing box 6 close to the feeding port 211 is in sliding contact with the side of the driving wheel 22 facing the discharging port 212, and the top end face of the mixing box 6 is located above and adjacent to the central axis of the driving wheel 22.

[0043] A mixing roller 62 is rotatably connected in the mixing box 6, the central axis of the mixing roller 62 is parallel to the central axis of the driving wheel 22, and a mixing blade is fixedly connected to the outer peripheral side of the mixing roller 62 in a spiral direction. The spreading box 2 is provided with a second transmission assembly 7, and when the driving wheel 22 rotates, the second transmission assembly 7 drives the mixing roller 62 to rotate.

[0044] The second transmission assembly 7 includes a connecting gear 71, a second transmission shaft 72, a connecting belt 73 and a rotating shaft 74; the second transmission shaft 72 is rotatably connected to the sowing box 2, the connecting gear 71 is fixedly connected to the outer peripheral side of the second transmission shaft 72, the connecting gear 71 is rotatably connected to the wall of the sowing box 2, and the connecting gear 71 is meshed with the transmission gear ring 41. The rotating shaft 74 is rotatably connected to the inner wall of the mixing box 6, the rotating shaft 74 and the mixing roller 62 are fixedly connected and coaxially arranged, the connecting belt 73 is connected end to end and slidably penetrates the mixing box 6 and the wall of the sowing box 2, and the connecting belt 73 is sleeved on the rotating shaft 74 and the outer peripheral side of the second transmission shaft 72.

[0045] When the driving wheel 22 rotates, the transmission gear ring 41 drives the second transmission shaft 72 to rotate through the connecting gear 71, and the connecting belt 73 drives the rotating shaft 74 to rotate, so that the mixing roller 62 enters the rotating state. When the soil is driven to the top of the mixing box 6 by the feeding sheet 221, the soil enters the mixing trough 61, and the mixing roller 62 crushes the soil to reduce the volume of the soil agglomerates. A discharge port 63 is provided on the side of the mixing box 6 facing away from the feed port 211, and the discharge port 63 is connected to the discharge port 212. The soil in the mixing trough 61 is discharged through the discharge port 63, and finally discharged from the mixing chamber 21 through the discharge port 212.

[0046] A toggle shaft 64 is rotatably connected to the wall of the mixing box 6 on the side away from the discharge port 212, and the toggle shaft 64 extends into the driving wheel 22. A toggle blade 641 is fixedly connected to the outer peripheral side of the toggle shaft 64, and there are multiple toggle blades 641 that are evenly spaced along the circumferential direction. A toggle belt 642 is sleeved between the toggle shaft 64 and the rotating shaft 74. When the rotating shaft 74 rotates, the toggle belt 642 drives the toggle shaft 64 to rotate. The rotation direction of the toggle shaft 64 is opposite to that of the driving wheel 22. At this time, the toggle blade 641 rotates with the toggle shaft 64, so that the toggle blade 641 cooperates with the feeding blade to initially crush the soil and reduce the volume of the soil.

[0047] A filter grille 65 is provided at the top of the mixing tank 6, and the filter grille 65 covers the notch of the mixing tank 61. One side of the filter grille 65 away from the feed port 211 is hinged to one side of the top of the mixing tank 6 close to the discharge port 212. A sliding column is fixedly connected to the bottom of the filter grille 65 and close to the feed port 211. A chute for the sliding column to slide up and down is opened on the top of the mixing tank 6, and there is a gap between the peripheral wall of the chute and the outer periphery of the sliding column. A driving spring 651 is arranged on the mixing tank 6. The driving spring 651 is installed in the chute. The top of the driving spring 651 abuts against the bottom of the sliding column, and the bottom of the driving spring 651 abuts against the bottom wall of the chute. When the driving spring 651 elastically releases, it drives the sliding column to move upward, so that one side of the filter grille 65 close to the feed port 211 moves upward. At this time, the filter grille 65 extends obliquely downward from the side of the feed port 211 to the side of the discharge port 212. The conveying sheet 221 drives the soil to be conveyed onto the filter grille 65. At this time, the filter grille 65 filters the larger soil lumps on the one hand, and on the other hand, the soil lumps move along the filter grille 65 towards the discharge port 212, reducing the accumulation of soil at the position of the filter grille 65 close to the feed port 211.

The conditioner in the storage tank 5 is input into the mixing tank 61 through the feed pipe 51.

[0049] See Figure 7 , a connecting sleeve 52 is sleeved on the outer periphery of the feed pipe 51, and a reciprocating thread sleeve 53 is sleeved on the outer periphery of the connecting sleeve 52. A limiting block 521 is fixedly connected to the outer periphery of the connecting sleeve 52, and the reciprocating thread sleeve 53 is provided with a limiting groove 531 extending in the vertical direction. The limiting block 521 slides up and down in the limiting groove 531, so that the connecting sleeve 52 and the reciprocating thread sleeve 53 are linked, and at the same time, the reciprocating thread sleeve 53 can axially slide on the outer periphery of the connecting sleeve 52.

A power bevel gear 252 is fixedly connected to the outer peripheral side of the power shaft 25, and the power bevel gear 252 is rotatably connected inside the box wall of the sowing box 2. A linkage bevel gear 441 is fixedly connected to the outer peripheral side of the connecting shaft 44, and the linkage bevel gear 441 is rotatably connected inside the box wall of the sowing box 2. The power bevel gear 252 is meshed with the linkage bevel gear 441. When the rotating shaft 74 (marked on the rotating roller 23) rotates, the linkage bevel gear 441 drives the power shaft 25 to rotate through the power bevel gear 252. Then, the power shaft 25 drives the connecting sleeve 52 to rotate through the power belt 251, so that the reciprocating thread sleeve 53 enters a rotating state. Then, under the action of the driving nut 24, the reciprocating thread sleeve 53 enters an up-and-down cyclic motion state. Figure 1 (marked in

[0051] A rolling block 54 slides up and down at the bottom of the reciprocating thread sleeve 53. A linkage block 532 is fixedly connected to the outer peripheral side of the reciprocating thread sleeve 53. The rolling block 54 is provided with a linkage groove 549 extending in the vertical direction. The linkage block 532 slides up and down in the linkage groove 549. The reciprocating thread sleeve 53 is provided with a power spring 533. The power spring 533 is installed in the linkage groove 549. One end of the power spring 533 abuts against the top of the linkage block 532, and the other end abuts against the top wall of the linkage groove 549. When the power spring 533 elastically releases, it drives the linkage block 532 to move downward.

[0052] A material groove 541 is formed in the rolling block 54, and the material groove 541 is communicated with the material conveying pipe 51. A plurality of sowing holes 542 are formed at the bottom of the rolling block 54, and the sowing holes 542 are evenly spaced. The sowing holes 542 communicate with the material groove 541. The rolling block 54 is provided with a plugging column 543. The plugging column 543 slides up and down in the sowing hole 542. There are a plurality of plugging columns 543, which correspond to the sowing holes 542 one by one. A sliding column 544 is fixedly connected to the top of the plugging column 543. The sliding column 544 is coaxially arranged with the plugging column 543. The outer diameter of the sliding column 544 is smaller than the diameter of the sowing hole 542. A linkage bar 545 is fixedly connected between the sliding columns 544, so that the sliding columns 544 are linked.

[0053] The rolling block 54 is fixedly installed with a mounting frame 546, and the mounting frame 546 is located inside the material tank 541. A power column 547 slides up and down on the mounting frame 546, and a linkage bar 545 is fixedly connected to the power column 547. A connecting spring 548 is sleeved on the outer peripheral side of the power column 547. The top of the connecting spring 548 abuts against the mounting frame 546, and the bottom of the connecting spring 548 abuts against the bottom of the linkage bar 545. When the connecting spring 548 elastically releases, it drives the linkage bar 545 to move downward, so that the blocking column 543 protrudes out of the spreading hole 542. At this time, the conditioner in the material tank 541 can be spread into the mixing tank 61 through the spreading hole 542. When the rolling block 54 moves downward, the rolling block 54 first contacts the filter grille 65 (the filter grille 65 is marked in Figure 3 the bid), and then drives the filter grille 65 to move downward until it abuts against the top of the mixing box 6. During the downward movement of the filter grille 65, the rolling block 54 rolls the soil clods on the filter grille 65, further reducing the volume of the soil clods. And during rolling, the blocking column 543 is abutted and slides into the spreading hole 542, blocking the spreading hole 542 and reducing the possibility of soil blocking the spreading hole 542 during rolling. When the rolling block 54 moves away from the filter grille 65, the connecting spring 548 drives the blocking column 543 to protrude into the spreading hole 542, so that the conditioner can be output into the material tank 541, facilitating the mixing of the conditioner and the soil.

[0054] The soil remediation device further includes a leveling plate, which is fixedly connected to the bottom of the machine body 1, and the leveling plate is located on the side of the spreading box 2 away from the plowshare 12. During use, there is a gap between the leveling plate and the ground, and the mixed soil discharged from the discharge port 212 and piled on the ground is leveled, further improving the mixing uniformity of the soil and the conditioner and reducing the possibility of the conditioner being blown away by the wind.

[0055] The implementation principle of a soil remediation device according to an embodiment of the present application is as follows: During use, first store the conditioner in the storage tank 5, and then start the machine body 1 to make the plowshare 12 move forward, driving the soil to turn over to both sides of the plowshare part 13. When the plowshare 12 moves forward, the stirring blade 232 stirs the soil into the driving wheel 22, and then the feeding piece 221 drives the soil into the mixing tank 61. When the feeding piece 221 drives the soil to move, the twisting blade 641 cooperates with the feeding piece 221 to initially crush the soil clods. When the soil falls on the filter grille 65, the soil with a smaller volume enters the mixing tank 61. At the same time, the rolling block 54 rotates and evenly spreads the conditioner into the mixing tank 61, so that the mixing roller 62 can evenly mix the conditioner and the soil in the mixing tank 61. When the rolling block 54 spreads the conditioner, the rolling block 54 moves up and down to crush the soil on the filter grille 65, further reducing the volume of the soil clods and improving the mixing effect of the soil and the conditioner. Finally, the mixed soil and conditioner are discharged from the discharge port 212.

[0056] On the other hand, the present application discloses a soil remediation method, comprising the following steps: Step 1: Store the conditioner in the storage box 5; Step 2: Start the body 1, and the body 1 drives the plow head 12 to move forward, driving the soil to be deflected to both sides of the plowshare portion 13; Step 3: When the plow head 12 moves forward, the deflecting blade 232 deflects the soil into the driving wheel 22. At this time, the feeding piece 221 drives the soil into the mixing tank 61. Then, the conditioner enters the mixing tank 61. Then, the mixing roller 62 crushes the soil while mixing the soil and the conditioner. Finally, the mixed soil is discharged from the discharge port 212.

[0057] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
