Description

Technical Field

[0001] The present invention relates to the technical field of soil remediation, and in particular to a soil pollution control and remediation device. Background Art

[0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. At present, in the field of soil remediation, commonly used means include physical, chemical and biological methods. For agricultural arable land, the commonly used method is to combine physical and chemical methods for management and remediation. Specifically, the remediation agent is sprayed on the contaminated arable land, and then the soil sprayed with the remediation agent is mixed to mix the remediation agent and soil evenly to achieve the remediation effect.

[0003] For example, the Chinese invention patent with application number 2024109251704 discloses a soil remediation device that can enhance the soil remediation effect. The device uses a soil crushing component to crush the soil, sprays the remediation liquid on the soil surface after crushing, and then uses a mixing component to mix the soil and the remediation liquid to make the remediation liquid and the soil evenly mixed. However, since the remediation liquid needs to be mixed simultaneously by the mixing component after spraying, the mixing component also adopts the principle of stirring the soil. This will cause the soil sprayed with the remediation liquid and moistened to adhere to the mixing component. After working for a long time, it will cause the surface of the mixing component to adhere to compacted soil, which is not conducive to uniform mixing.

[0004] The Chinese invention patent with application number 2023109362986 discloses a circulating soil pollution remediation device, which includes a walking platform, a soil-digging operation structure, a crushing mechanism, a mixing mechanism and other components. Its working principle is that the walking platform moves, and the soil is dug up and transported to the mixing mechanism on the walking platform through the soil-digging operation structure. The mixing mechanism can add remediation liquid to the soil and mix it, and then discharge the mixed soil from the rear drop port, so as to achieve the purpose of soil treatment. The soil mixing method adopts a mixing mechanism set on the platform for mixing. This treatment method can improve the mixing uniformity of soil and remediation liquid to a certain extent, but because its mixing method still adopts a stirring method, and the stirring method is a common and commonly used mixing structure of existing soil remediation devices; the stirring mechanism also has the problem of soil adhesion and needs to be cleaned regularly, and its overall structure size is large, and the use cost and purchase cost are high. Summary of the invention

The mixing assembly includes at least one shovel plate, and a guide plate is connected to the end of the shovel plate away from the crushing unit. A plurality of injection pipes are arranged below the end of the guide plate away from the shovel plate.

[0007] Furthermore, the guide plate is arranged to extend gradually upwardly tilted from one end connected to the shovel plate to the other end.

[0008] Furthermore, a vibration plate is provided on the upper surface of the guide plate, and one end of the vibration plate close to the shovel plate is connected to the middle area of ​​the guide plate.

[0009] Furthermore, the mixing assembly includes a first shovel plate and a second shovel plate arranged at intervals along the vertical direction, the first shovel plate is connected to the first guide plate, and the second shovel plate is connected to the second guide plate; along the vertical direction, the distance between the shoveling end of the first shovel plate and the shoveling section of the second shovel plate is smaller than the distance between the first guide plate and the second guide plate.

[0010] Furthermore, the first shovel plate is connected to a first tube, on which a plurality of first injection tubes and a plurality of second injection tubes are arranged at intervals, the injection direction of the first injection tube intersects with the extension direction of the first guide plate, and the injection direction of the second injection tube intersects with the extension direction of the second guide plate.

[0011] Furthermore, the mixing unit also includes a third guide plate arranged above the first guide plate, and the third guide plate is located at an end of the first guide plate away from the first shovel plate; in the direction from the crushing unit to the mixing unit, the third guide plate is inclined from top to bottom.

[0012] Furthermore, a sounding roller group is arranged between the crushing unit and the mixing unit, and the sounding roller group is connected to the power telescopic rod.

[0013] Furthermore, the crushing unit includes a crushing shaft and a pressure plate assembly arranged between the crushing shaft and the depth measuring roller group, the pressure plate assembly includes a connecting plate, a pressure plate rotatably connected to the lower end of the connecting plate through a first axis, and a first compression spring arranged between the pressure plate and the frame, the first compression spring can provide a downward elastic force to the pressure plate, and the axis of the first axis is perpendicular to the spacing direction of the crushing unit and the mixing unit and is arranged horizontally.

[0014] Furthermore, the pressure plate assembly also includes a first pressure rod, one end of which is hingedly connected to the pressure plate, and the other end is slidably sleeved with a ring, which is connected to the frame pin shaft, and the first compression spring is sleeved on the periphery of the first pressure rod, one end of which is abutted against the ring, and the other end is abutted against the pressure plate.

[0015] Furthermore, the depth measuring roller group includes a support plate connected to the frame, two second guide rods vertically arranged on the support plate, a roller rotatably arranged at the lower end of the second guide rod, a second compression spring arranged between the support plate and the roller, and a pressure sensor arranged between the second compression spring and the support plate.

[0016] The soil pollution control and remediation device disclosed in the present invention has the following beneficial effects compared with the prior art.

[0017] 1. The method of mixing the soil by a mixing unit after crushing the soil makes it easier to mix the soil conditioner with the soil. The soil mixing unit scoops up the soil with a shovel plate and sprays the soil conditioner. This can not only ensure the mixing effect of the conditioner and the soil, but also avoids the mixing by the stirring method commonly used in the art, thus avoiding the disadvantage of the soil and the stirring device being adhered to each other due to the stirring and mixing. Moreover, through this treatment method, the soil falls under the action of gravity after being separated from the guide plate, which can ensure the fluffy effect of the soil and has good air permeability. Compared with the prior art, it can improve the soil repair effect and avoid the problem of poor air permeability caused by soil pressurization and agglomeration due to stirring.

[0018] 2. The end of the shovel plate contacts the crushed ground and scoops up the crushed soil. As the agricultural machinery drives the frame to move, the soil is scooped up by the shovel plate and passes through the guide plate to the rear end of the guide plate under the action of inertia, then flows down from the rear end of the guide plate and separates from the guide plate, and is flipped upward by the guide of the guide plate. At the same time, the improver is sprayed out through the injection pipe. The sprayed improver contacts and mixes with the soil passing through the guide plate, thereby improving the mixing effect of the soil and the improver.

[0019] 3. By setting a vibration plate on the guide plate, the vibration plate can vibrate and shake the soil, and the scattered soil can be better mixed with the sprayed soil conditioner, thereby further improving the mixing effect of the soil and the soil conditioner and improving the repair effect.

[0020] 4. The first shovel plate and the second shovel plate of the upper and lower structures can shovel the soil in layers and spray the soil conditioner in layers, thereby further improving the mixing effect of the soil conditioner and the soil and improving the effect of soil repair.

DETAILED DESCRIPTION

[0037] The present invention will now be described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and thus only show the components related to the present invention.

[0038] Embodiment 1 The technical solution of the present invention is: Figure 1-Figure 8 The present invention discloses a soil pollution control and restoration device, comprising: Rack 1; A crushing unit 2 is arranged at the front end below the frame 1 and is used for crushing the soil; The mixing unit 3 is arranged at the rear end below the frame 1, and includes a power telescopic rod 30 connected to the frame 1 and a mixing assembly 33 arranged at the lower end of the power telescopic rod 30. The mixing assembly 33 includes at least one shovel plate, and a guide plate is connected to the end of the shovel plate away from the crushing unit 2. A plurality of injection pipes are arranged below the end of the guide plate away from the shovel plate.

[0039] Specifically, as an embodiment, the frame 1 is a rectangular frame structure, which is used to provide support for the entire device, and is connected by welding with rectangular rods. End plates 11 are welded in parallel on both sides of the frame 1, and a top cover 10 is installed on the top. The crushing unit 2 includes two first side plates 21 that are detachably fixedly connected to the end plates 11, a transmission component 20 arranged on the frame 1, and a crushing shaft 22 that is rotatably connected to the two first side plates 21 at both ends. The outer peripheral surface of the crushing shaft 22 is provided with crushing teeth 23, and the crushing shaft 22 is connected to the transmission component 20 in a transmission manner. When working, the frame 1 is connected to the agricultural machinery, and the frame 1 is dragged by the agricultural machinery to move forward, and the machine is kept The frame 1 is in a horizontal state and is connected to the transmission component 20 through the agricultural machinery, so that the power is transmitted to the crushing shaft 22. After the crushing shaft 22 rotates, it drives the crushing teeth 23 to rotate to crush the land, thereby achieving a crushing effect. The mixing unit 3 includes two second side plates 31 connected to the two end plates 11, and each second side plate 31 is detachably provided with a power telescopic rod 30, and the lower end of the power telescopic rod 30 is provided with a connecting frame 301; a shovel plate is connected through the connecting frame 301. Specifically, the shovel plate is horizontally arranged and parallel to the crushing shaft 22, and a guide plate is connected to the end of the shovel plate, and the rear end of the guide plate is inclined upward. The guide plate is obliquely arranged, and a spray pipe is fixedly arranged below the rear end of the guide plate. When working, the spray pipe is used to connect with the supply source of the improvement liquid, and the improvement liquid of a certain pressure is supplied to the supply pipe. By controlling the extension amount of the power telescopic rod 30, the end of the shovel plate is made to contact with the ground after being crushed, and the crushed soil is scooped up. As the agricultural machinery drives the frame 1 to move, the soil is scooped up by the shovel plate and passes through the guide plate to the rear end of the guide plate under the action of inertia, and then flows down from the rear end of the guide plate and separates from the guide plate, and is turned up by the guide of the guide plate, and at the same time, the improver is sprayed out through the spray pipe, and the improver is sprayed and mixed with the soil passing through the guide plate, and then the improver is sprayed. And it can improve the mixing effect of soil and amendment. In this way, not only the mixing effect of amendment and soil can be guaranteed, but also stirring and mixing by the stirring method commonly used in the field is not required, thus avoiding the disadvantage of soil and stirring device adhesion caused by stirring and mixing. Moreover, through the processing method of the present application, the soil falls under the action of gravity after separation from the guide plate, which can ensure the fluffy effect of soil and has good air permeability. Compared with the prior art, it can improve the soil remediation effect and avoid the problem of poor air permeability caused by soil pressurization and agglomeration due to stirring. Compared with the existing soil remediation device, it can achieve better improvement effect.

[0040] Specifically, the agricultural machinery may be agricultural tractors and other mechanical equipment, and a lifting lug (not shown in the figure) may be welded on the frame 1 to be connected to the hydraulic lifting frame of the tractor, so as to lift and adjust the posture of the frame 1; it should be noted that the hydraulic lifting frame mounted at the rear of agricultural machinery such as tractors and the method of using the same belong to the prior art in the field, which will not be described in detail here, and those skilled in the art should understand and know it.

[0041] Furthermore, as a preferred embodiment, an atomizing nozzle is installed at the end of the spray pipe so that the improver is in an atomized state after being sprayed out, achieving a better effect of spraying and mixing with the soil.

[0042] Furthermore, it should be noted that the improvement liquid supply source used in the present application may include a liquid storage barrel and a liquid pump, the liquid storage barrel is used to store liquid configured with the improvement liquid, and the liquid pump is used to pump the improvement liquid to the injection pipe at a certain pressure.

[0043] Furthermore, as a preferred embodiment, the guide plate is gradually extended and tilted upward from one end connected to the shovel plate to the other end. By setting the guide plate to be tilted, the soil can be directed upward, so that the soil has the inertia to flip upward when it is separated from the guide plate, and the soil can be turned over during the process of turning up and falling, so as to better mix with the improver sprayed from the injection pipe, achieve a better mixing effect, and ensure the soil improvement and repair effect.

[0044] Further, it can be understood that the effect of soil improvement is related to the improvement effect of the improver itself on the one hand, and to the mixing uniformity of the improver and the soil on the other hand. Under the same condition of the improver, the higher the mixing uniformity of the soil and the improver, the better the improvement effect of the soil can be achieved. As a preferred embodiment, in order to further improve the mixing effect of the soil and the improver, reference is made to Fig. 9 , Fig.12 , Fig.13 The upper surface of the guide plate is also provided with a vibration plate, and one end of the vibration plate close to the shovel plate is connected to the middle area of ​​the guide plate. Specifically, the vibration plate adopts an elastic rigid plate, one end of which is detachably fixedly connected to the middle area of ​​the guide plate, and the other end is arranged parallel to the guide plate along the extension direction of the guide plate and partially extends out of the guide plate, Fig.12 , Fig.13 , the vibration plate has Fig.12 The first working state shown and Fig.13 In the second working state shown, in the first working state, the end of the vibration plate is separated from the guide plate and bent upward, and in the second working state, the vibration plate and the guide plate are arranged in parallel in a close fit, and the vibration plate is configured to be able to switch back and forth between the first working state and the second working state when the soil flows through the guide plate, so that the end vibrates. Through this setting, the soil can be shaken to shake off the soil passing through the guide plate so that the soil can be better mixed with the improvement liquid sprayed from the injection pipe, thereby further improving the mixing effect of the improver and the soil.

[0045] Further, as a specific implementation method, refer to Figure 6-Figure 10 , Fig.12 , Fig.13The shovel plate includes a first shovel plate 330 and a second shovel plate 331, the guide plate includes a first guide plate 3302 and a second guide plate 3310, the vibration plate includes a first vibration plate 33021 and a second vibration plate 3311, and the mixing assembly 33 includes a first shovel plate 330 and a second shovel plate 331 spaced apart in the vertical direction, the first shovel plate 330 is connected to the first guide plate 3302, and the second shovel plate 331 is connected to the second guide plate 3310; in the vertical direction, the distance between the shoveling end of the first shovel plate 330 and the shoveling section of the second shovel plate 331 is smaller than the distance between the first guide plate 3302 and the second guide plate 3310.

[0046] As a specific implementation, a connecting frame 301 is provided at the lower end of the power telescopic rod 30, and the shovel plate includes a first shovel plate 330 and a second shovel plate 331 arranged at intervals, and the first shovel plate 330 and the second shovel plate 331 are both detachably fixedly connected to the connecting frame 301, wherein the first shovel plate 330 is located above the second shovel plate 331, and the shoveling ends of the first shovel plate 330 and the second shovel plate 331 are both arranged to be tilted downward, and the shoveling end of the first shovel plate 330 is tilted downward for a longer length, and the shoveling end of the first shovel plate 330 is closer to the crushing unit 2, and the first guide plate 3302 connected to the first shovel plate 330 and the second guide plate 331 connected to the second shovel plate 331 are arranged in parallel, so that the first shovel plate 330 and the second shovel plate 331 are connected to each other. The distance L between the shoveling ends of 31 is smaller than the distance between the first guide plate 3302 and the second guide plate 3310. With this arrangement, when working, the agricultural machinery drags the frame 1 to advance, firstly crushes the soil through the crushing unit 2, and then controls the telescopic length of the power telescopic rod 30 to scoop up and mix the crushed soil through the first shovel plate 330 and the second shovel plate 331. When in use, the thickness of the soil shoveled up by the first shovel plate 330 is 10mm-20mm, and the vertical distance between the first shovel plate 330 and the second shovel plate 331 is constant. Then the thickness of the soil shoveled up by the second shovel plate 331 is the distance in the vertical direction between the first shovel plate 330 and the second shovel plate 331, which is generally 10mm-15mm.

[0047] Specifically, as a preferred embodiment, the distance between the lower surface of the first guide plate 3302 and the upper surface of the second guide plate 3310 is L1, then L1=1.2L-1.5L, thereby ensuring that there is sufficient space between the first guide plate 3302 and the second guide plate 3310 after the soil is shoveled up by the second shovel plate 331, which is beneficial to improving the effect of subsequent vibration plates on soil vibration and dispersion, thereby ensuring the uniformity of mixing of soil and mixed liquid.

[0048] Further, as a preferred embodiment, the first shovel plate 330 is connected to the first tube 335, and a plurality of first injection tubes 3360 and a plurality of second injection tubes 3361 are arranged at intervals on the first tube 335. The injection direction of the first injection tube 3360 intersects with the extension direction of the first guide plate 3302, and the injection direction of the second injection tube 3361 intersects with the extension direction of the second guide plate 3310.

[0049] Specifically, refer to Fig. 9 , Fig.12 , Fig.13 , the length of the second guide plate 3310 extending backward is greater than the length of the first guide plate 3302 extending backward. Through this arrangement, it is ensured that the soil is separated from the first guide plate 3302 after passing through the second guide plate 3310 to the tail, ensuring that there is a large space, so that the soil on the second guide plate 3310 can be better dispersed after being vibrated by the vibration plate; the second pipe 336 is fixed below the first guide plate 3302, and a plurality of first injection pipes 3360 and a plurality of second injection pipes 3361 arranged upwardly and evenly spaced are arranged on the second pipe 336. The improvement liquid injected by the first injection pipe 3360 can be sprayed and mixed onto the soil passing through the first guide plate 3302, and the soil improvement liquid injected by the second injection pipe 3361 can be sprayed and mixed onto the upper surface of the soil passing through the second guide plate 3310. The second guide plate 3310 is fixed below A first pipe 335 is provided, and a third injection pipe 3351 for injecting obliquely downward and a fourth injection pipe 3352 for injecting obliquely upward are evenly spaced on the first pipe 335. The soil conditioner passing through the fourth injection pipe 3352 can be sprayed and mixed onto the lower surface of the soil passing through the second guide plate 3310, and is sprayed simultaneously onto the upper and lower surfaces of the middle layer of soil passing through the second guide plate 3310 through the fourth injection pipe 3352 and the second injection pipe 3361, thereby ensuring uniform mixing of the soil and the soil conditioner; the soil conditioner is sprayed downward through the fourth injection pipe 3352, thereby spraying the soil conditioner onto the surface of the lowest layer of soil, so that the soil in the lower layer can also contact and mix with the soil conditioner, thereby spraying the soil conditioner on the soil in layers through three layers to ensure uniform mixing of the soil and the soil conditioner.

[0050] Further, as a preferred embodiment, refer to Figure 7 , Fig. 9 The mixing unit 3 also includes a third guide plate 32 arranged above the first guide plate 3302, and the third guide plate 32 is located at an end of the first guide plate 3302 away from the first shovel plate 330; in the direction from the crushing unit 2 to the mixing unit 3, the third guide plate 32 is inclined from top to bottom.

[0051] Specifically, the third guide plate 32 is fixedly connected to the frame 1 or to the connecting frame 301. By setting the third guide plate 32, after the soil is separated from the first guide plate 3302 after being guided by the first guide plate 3302, it will contact and guide the third guide plate 32 at the rear. The third guide plate 32 moves synchronously with the frame 1, thereby providing a downward force for the soil passing through the first guide plate 3302. After the guidance, the soil can be guided downward to change the direction of soil movement. After passing through the third guide plate 32, the soil moves downward and has a certain collision effect with the soil passing through the second guide plate 3310, and collides and mixes with the soil passing through the second guide plate 3310, thereby further improving the mixing uniformity.

[0052] Embodiment 2 The present invention discloses a soil pollution control and restoration device, referring to Figure 8-Figure 10 , Figure 12-Figure 15 , which is different from the first embodiment in that: The first guide plate 3302 is provided with a first vibration plate 33021, and the second guide plate 3310 is provided with a second vibration plate 3311. A plurality of partition plates 332 are evenly spaced between the first shovel plate 330 and the second shovel plate 331. The plate surface of the partition plate 332 is perpendicular to the first shovel plate 330 and the second shovel plate 331, and also includes a third axis 333 parallel to the extension direction of the first shovel plate 330 and the second shovel plate 331. The third axis 333 passes through the plurality of partition plates 332 and rotates with the partition plates 332. Between two adjacent partition plates 332, the third axis 333 is provided. A passive wheel 334 is provided on each shaft 333. A fourth shaft 3304 is provided below the first guide plate 3302 and parallel to the third shaft 333. The third shaft 333 is transmission-connected with a transmission wheel 3331. The transmission wheel 3331 and the fourth shaft 3304 are transmission-connected through a transmission member 3330. A first driving unit 3303 is provided below the fourth shaft 3304 and the first guide plate 3302 of the third shaft 333. The first driving unit 3303 is drivingly connected to the fourth shaft 3304. The first driving unit 3303 is drivingly connected to the first vibration plate 33021. Specifically, during operation, after the soil is scooped up by the second shovel plate 331, it will pass through the first shovel plate 330 and move relative to the first shovel plate 330, and the soil will move relative to the passive wheel 334. When the soil passes through the passive wheel 334, it can drive the third shaft 333 to rotate. When the third shaft 333 rotates, it can drive the fourth shaft 3304 to rotate. The rotation of the fourth shaft 3304 drives the first driving unit 3303 to drive the first vibration plate 33021 to switch between the first working state and the second working state to generate vibration.

[0053] Further, specifically, the first driving unit 3303 includes at least two parts respectively arranged at both ends of the first guide plate 3302, the first driving unit 3303 includes a first shell 33031 which is detachably fixed to the lower surface of the first guide plate 3302, a first guide hole arranged on the first guide plate 3302 and coaxially arranged with the first shell 33031, a first rigid rod 33035 guided in the first guide hole, a first plate 33032 connected to the first rigid rod 33035, and a first elastic member 33034 arranged between the first guide plate and the first plate 33032, the fourth shaft 3304 is inserted into the side wall of the first shell 33031 and is rotatably matched with the first shell 33031, and a cam is arranged on the outer peripheral surface of the fourth shaft 3304 located in the first shell 33031, and the cam is slidably matched with a side of the first plate 33032 away from the first rigid rod 33035, refer to Fig.14 , when the cam is opposite to the first plate 33032, the first plate 33032 is pushed to contact the outer peripheral surface of the fourth shaft 3304 under the elastic force of the first elastic member 33034, and the end of the first rigid rod 33035 is located inside the first guide hole. At this time, the first elastic rod is in the second working state. As the fourth shaft 3304 rotates, the cam contacts the first plate 33032 and pushes the first plate 33032 to squeeze and compress the first elastic member 33034, so that the first rigid rod 33035 extends out of the first guide hole and pushes the first elastic rod to switch the first elastic plate to Fig.12 In the first working state shown, as the fourth shaft 3304 rotates, the state of the first elastic plate switches back and forth under the elastic force of the first elastic rod itself, generating vibration.
