Among them, heavy metals are more prominent in inorganic soil pollutants, mainly because heavy metals cannot be decomposed by soil microorganisms and are easy to accumulate, resulting in heavy metal pollution. Soil remediation is to directly add contaminated soil into the device, then add reagents to the contaminated soil in the device, fully mix after stirring by the engineering machinery, so that the reagents and harmful components in the contaminated soil have physical and chemical reactions, decompose or seal the harmful components in the dense low-permeability solidified body, thereby changing the form of harmful components and reducing their migration in the environment to achieve soil remediation.

Detailed Implementation

[0018] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0019] Please see Figures 1-6As shown, the present application provides a geological water conservancy ecological restoration device, which comprises a movable treatment box 1, two cavities are arranged in the treatment box 1, a longitudinal soil drilling adjusting unit moving in the vertical direction is arranged in one cavity; A soil turning unit is arranged in the other cavity and moves up and down, a conveying unit for conveying the soil after turning is arranged on one side of the soil turning unit in the other cavity, a screening unit is arranged on one side of the top of the conveying unit, and a return port 27 is arranged below the screening unit; A rolling unit for compacting the soil after returning is arranged on one side of the end of the treatment box 1; The longitudinal soil drilling adjusting unit comprises a transverse oil cylinder 6 arranged in one cavity, a conveying frame 8 is connected to the pushing end of the transverse oil cylinder 6 and moves transversely in one cavity, two limiting frames 7 are connected to the inside of the conveying frame 8, the two limiting frames 7 are close to or away from each other at the same time, a guide frame 10 moving in the vertical direction is arranged in the inside of each limiting frame 7, and the two guide frames 10 move synchronously; A soil drilling rod 11 is arranged on the lower surface of the guide frame 10 and penetrates the bottom of the limiting frame 7.

[0020] Initially, the height of the soil drilling rod 11 is higher than the height of the soil to be repaired to avoid collision during movement, the conveying frame 8 is transversely pushed by the transverse oil cylinder 6 to move in one cavity, the entire drilling unit is aligned with the longitudinal strip to be processed, and the ecological restoration of the geological soil is carried out, the width of the soil drilling is adjusted according to the repair width by the longitudinal soil drilling adjusting unit, when the repair width is large, the two limiting frames 7 are away from each other at the same time and move in the conveying frame 8, then the two guide frames 10 are lowered synchronously, thereby driving the soil drilling rod 11 to slide downward along the limiting frame 7 by a certain height, and the soil at different depths is drilled to loosen the hard soil; when the repair width is small, the two limiting frames 7 are close to each other synchronously, driving the soil drilling rod 11 inside to be close, the drilling width is small, the pollution layer at a specific depth is treated by accurate drilling and screening, the lower unpolluted soil layer is avoided to be damaged, and the same drilling force is applied to the soil at different points to ensure the consistency of the soil loosening effect, the physical boundary of the drilling operation is determined in this way to ensure that the soil drilling rod 11 does not exceed the preset repair area, and the interference to the non-target area is realized; It should be noted that when the geological soil is drilled, the repair agent is directly sprayed into the soil to be repaired, thereby improving the repair effect of the agent; When the soil is drilled or pretreated, the rear soil turning unit starts to work, thoroughly turns up and breaks the soil, which is then collected by the conveying unit and transported upward. The soil is transported to the top distribution unit, where large impurities such as stones and plastics are screened out, and the fine and clean soil falls through the return port 27. The soil is finally backfilled to the excavated land. With the forward movement of the treatment box 1, the rolling unit at the end rolls the backfilled soil to restore the surface flatness, prevent dust, and create conditions for subsequent vegetation restoration. The entire repair process is time-saving and efficient.

[0021] Referring to Figure 3 and Figure 4 As shown in the drawings, the middle part of the bottom surface of the conveying frame 8 is provided with a fixed plate 21, and the upper surface of the fixed plate 21 is provided with a double-shaft motor. The two sides of the double-shaft motor are provided with lead screws 9 which are screwed to the corresponding limiting racks 7. The bottom surface of the fixed plate 21 is provided with a vertical oil cylinder 22, and the pushing end of the vertical oil cylinder 22 is connected with a connecting piece 23. The two ends of the connecting piece 23 are movably connected with guide racks 10.

[0022] Since the connecting piece 23 is connected with the two guide racks 10 at the same time, when the vertical oil cylinder 22 is extended or retracted, the force is transmitted to the two guide racks 10 through the connecting piece 23, synchronously driving the guide racks 10 to vertically slide along the limiting racks 7, realizing the synchronous drilling and lifting of the two soil drilling rods 11. When the double-shaft motor is started, the two lead screws 9 rotate synchronously. Since the lead screws 9 are screwed with the limiting racks 7, the rotary motion of the lead screws 9 will be converted into the linear motion of the limiting racks 7, which in turn drives the two limiting racks 7 to simultaneously approach or move away from each other in the conveying frame 8.

[0023] Referring to Figure 5 As shown in the drawings, the two ends of the connecting piece 23 are provided with movable cavities, and the end of each guide rack 10 is connected with a limiting block 26 which is limited to slide in the movable cavity. One side of the limiting block 26 is connected with a spring 25 which is connected with the inner wall of one end of the movable cavity, and the other side of the limiting block 26 is sleeved with a spring 24 which is connected with the inner wall of the other end of the movable cavity.

[0024] The spring one 24 and the spring two 25 are respectively located on both sides of the limiting block 26 and are in a pre-compressed state, when the soil repair width becomes larger, the two limiting frames 7 move away from each other and pull the limiting block 26 to limit sliding in the corresponding movable cavity, at this time, the spring two 25 is elastically stretched, and the spring one 24 is elastically compressed, and because the limiting block 26 limits sliding in the connecting piece 23, it is ensured that the connecting piece 23 is lowered in height, and the guide frames 10 on both sides are lowered synchronously, when the soil repair width becomes smaller, the two limiting frames 7 move closer to each other and pull the limiting block 26 to limit sliding in the corresponding movable cavity, at this time, the spring two 25 is elastically compressed, and the spring one 24 is elastically stretched, meeting the use in two states.

[0025] Referring to Figure 2 As shown in the figure, the soil turning unit includes a lifting frame 14 which is provided in another cavity and is limited to lift, the lifting frame 14 is connected with a lifting oil cylinder 15 above, and the lifting frame 14 is provided with a soil turning roller 12 below, and the outer surface of the soil turning roller 12 is provided with a plurality of soil turning frames 28.

[0026] When the processing box 1 moves to the working area, the lifting oil cylinder 15 is extended, the lifting frame 14 is pushed to vertically descend along another cavity, the soil turning roller 12 is accurately set in the soil by controlling the stroke of the lifting oil cylinder 15, the soil turning roller 12 starts to rotate at high speed, the soil turning frame 28 is cut into the soil, the soil turning frame 28 has a certain bending angle or cutting edge, the hardened soil is cut into small pieces, the deep soil is turned to the surface, the soil is thrown backward by the centrifugal force of rotation, and is directly sent to the adjacent conveying unit, realizing the connection.

[0027] Referring to Figure 2 As shown in the figure, the conveying unit includes an inclined conveying channel 13, the bottom of the conveying channel 13 is provided with an inlet which is arranged towards the soil turning frame 28, and the top side of the conveying channel 13 is provided with an outlet.

[0028] When the soil turning roller 12 rotates at high speed and throws the soil backward, the soil directly falls into the inlet of the conveying channel 13, avoiding the waste and secondary pollution caused by the scattering of the soil, realizing the turning and conveying at the same time, the soil lifted by the conveying channel 13 falls out from the top outlet, directly enters the distributing unit, and starts to screen the gravel and plastic.

[0029] Referring to Figure 2 and Figure 6 As shown in the figure, the distributing unit includes a limiting cavity 18 which is inclined arranged in another cavity, the limiting cavity 18 is consistent with the center of the outlet of the conveying channel 13; The inner part of the limiting cavity 18 is rotatably installed with a screening cylinder 16, the inner cavity of the screening cylinder 16 is rotatably installed with an auger 17, the outer side of the bottom of the screening cylinder 16 is fixedly sleeved with a large gear, the bottom of the screening cylinder 16 is provided with an air channel for blowing air flow along the advancing direction of the auger 17, the surface of the auger 17 is provided with a plurality of air holes 29, and the bottom of the inner cavity of the limiting cavity 18 is provided with a discharging cavity opening 19 for the screened soil to fall off, and the discharging cavity opening 19 is communicated with a return port 27 below; Another cavity is installed with a gear 20 driven by a servo motor, and the gear 20 is engaged with the large gear.

The top and bottom of the screening cylinder 16 are respectively provided with notches, and the two notches are respectively communicated with the top and bottom of the limiting cavity 18.

[0030] The soil falls from the outlet of the conveying channel 13, and since the inlet of the limiting cavity 18 is consistent with the center of the outlet of the conveying channel 13, the soil accurately enters the inside of the screening cylinder 16. At this time, the screening cylinder 16 is rotating under the driving of the gear 20, and the rotation of the screening cylinder 16 makes the soil tumble in the cylinder, and the fine soil particles pass through the screen holes of the cylinder wall and fall into the bottom of the inner cavity of the limiting cavity 18, and finally fall through the discharging cavity opening 19 to the return port 27 and finally return to the dug land. The air flow blown by the air channel flows along the advancing direction of the auger 17, blows up the light plastic fragments, dry leaves and branches, etc., so that they are suspended, and the large pieces of gravel are distributed at the bottom of the screening cylinder 16 under the action of gravity. The air holes 29 on the surface of the auger 17 also blow out air flow, which blows away the wet soil adhered to the screen holes, keeping the screen holes unobstructed. The light impurities blown up by the air flow, as well as the large pieces of gravel that cannot pass through the screen holes, are left in the screening cylinder 16. When the light impurities are transported to the top of the screening cylinder 16, the top notch on the cylinder wall of the screening cylinder 16 is communicated with the top of the limiting cavity 18, and the impurities fall into the collecting bin 2 through this notch, realizing the winnowing of light plastic. When the two baffles 3 are extracted, the light impurities are in the upper part of the screening cylinder 16 and the large pieces of gravel are in the bottom of the screening cylinder 16, and they fall into the corresponding collecting bins 2; when the baffles 3 are inserted, the collection is temporarily suspended.

[0032] When the soil is compacted, the turnover oil cylinder is extended, the pushing end of the turnover oil cylinder pushes the rotating plate 4, so that it rotates downward around the connecting point (fulcrum) with the base of the box, the pressure wheel 5 descends with the rotating plate 4, contacts the ground soil, and as the oil cylinder continues to apply a pushing force, the pressure wheel 5 is pressed on the soil surface with a certain pressure, when the device moves, the pressure wheel 5 rolls, and the backfilled soft soil is compacted and leveled.

[0033] In use, when the repair width is large, the two limiting frames 7 are simultaneously away from each other and are limited to slide in the transfer frame 8, then the two guide frames 10 are synchronously lowered, and the soil drilling rod 11 is driven to slide downward along the limiting frame 7 to a specific height, so that the soil at different depths is drilled and the hard soil is loosened; when the repair width is small, the two limiting frames 7 are synchronously close to each other, and the soil drilling rod 11 inside is driven to be close, so that the drilling width is small, the pollution layer at a specific depth is treated through accurate drilling and screening, the underlying non-polluted soil layer is avoided from being damaged, the same drilling force is applied to the soil at different points, the consistency of the soil loosening effect is ensured, the physical boundary of the drilling operation is delimited in this way, the soil drilling rod 11 is ensured not to exceed the preset repair area, and the interference to the non-target area is realized. Through the movable connection of the connecting piece 23 and the guide frame 10, when the soil repair width is large, the two limiting frames 7 are away from each other and pull the limiting block 26 to limit to slide in the corresponding movable cavity, at this time, the spring two 25 is elastically stretched, and the spring one 24 is elastically compressed, and because the limiting block 26 is limited to slide in the connecting piece 23, the connecting piece 23 is ensured to be synchronously lowered when the height is lowered, and when the soil repair width is small, the two limiting frames 7 are close to each other and pull the limiting block 26 to limit to slide in the corresponding movable cavity, at this time, the spring two 25 is elastically compressed, and the spring one 24 is elastically stretched, and the use in the two repair states is met. Through the setting of the material distribution unit, the airflow blown by the air duct flows along the advancing direction of the auger 17, blows up the light plastic fragments, dry branches and leaves and the like, so that they are suspended, and the large stones are distributed at the bottom of the screening cylinder 16 under the action of gravity, the air holes 29 on the surface of the auger 17 simultaneously spray air flow to blow away the moist soil adhered to the screen holes, so that the screen holes are kept unblocked, the light impurities blown up by the airflow and the large stones which cannot pass through the screen holes are left in the screening cylinder 16, when the light impurities are transported to the top of the screening cylinder 16, the top gap on the cylinder wall of the screening cylinder 16 is communicated with the top of the limiting cavity 18, and the impurities fall into the collecting bin 2 through the gap, so that the light plastic is wind selected, and when the two baffles 3 are drawn out, because the light impurities are at the upper part of the screening cylinder 16 and the large stones are at the bottom of the screening cylinder 16, they fall into the corresponding collecting bin 2.
