Description

Technical Field

[0001] The invention relates to the field of soil remediation, in particular to a device for remediating soil contaminated by agricultural solid waste. Background Art

[0002] Solid construction waste mainly includes the slag generated during the construction process, abandoned building materials (such as bricks, concrete blocks, tiles), etc. When these substances enter the soil, they change the physical, chemical and biological properties of the soil, making it no longer suitable for normal ecological functions or land use, causing soil pollution. For example, a large amount of slag piled on the land will cover the original vegetation and destroy the soil structure, and some materials in the abandoned solid construction waste (such as cement and lime) may alkaline the soil. For alkaline soil, acidic liquid can be added through soil remediation equipment to adjust the pH value of the soil.

[0003] When repairing soil contaminated by construction solid waste, mechanical equipment such as excavators are generally used to clean up large areas of construction waste first, and then some residual construction solid waste on the soil surface, such as concrete stones, are removed manually. However, since construction solid waste has been piled on the soil surface for a long time, the concrete stones will gradually settle under the influence of rain erosion, gravity and other factors. Rainwater will make the soil loose, and the weight of the stones will cause them to slowly sink and embed into the soil. Therefore, the concrete stones embedded in the soil cannot be effectively removed by the naked eye. If the drug is sprayed directly on the soil surface at this time, the stones may cause the repair solution to accumulate on the soil surface or in the shallow layer, and it cannot fully penetrate into the soil, resulting in a waste of the repair solution. Moreover, if there are large gaps between the stones, the repair solution may quickly lose through these gaps and cannot play its due role in the soil.

[0004] In view of this, the present invention provides a device for repairing soil contaminated by agricultural solid waste. Summary of the invention

[0007] Preferably, a medicine spreading assembly for inserting into soil for medicine spreading and repair is provided on the base plate and the liquid outlet pipe 1, and the medicine spreading assembly includes connecting rods rotatably connected to the two rotating disks respectively, and the lower ends of the connecting rods are rotatably connected to L-shaped rods, and the two side walls of the isolation plate close to the connecting rods are fixedly connected to limit frames, and the L-shaped rods are slidably connected in the limit frames. The two L-shaped rods pass through one end of the limit frames and are commonly fixedly connected to liquid outlet pipe 2, liquid outlet pipe 2 is slidably connected in liquid outlet pipe 1, and an auxiliary spring is fixedly connected between liquid outlet pipe 2 and liquid outlet pipe 1, and the inner wall of liquid outlet pipe 2 is slidably connected to a T-shaped tube, and the lower part of the T-shaped tube is evenly fixedly connected to a plurality of conical tubes, and each conical tube is provided with a plurality of leakage holes.

[0008] Preferably, a sealing column is fixedly connected to the inner wall of the second liquid outlet pipe, and a sealing plate is fixedly connected to the inner wall of the first liquid outlet pipe.

[0011] Preferably, the rack rod passes through the base plate and is fixedly connected to one end close to the polygonal cam with a plurality of protruding columns.

[0012] Preferably, the outer side wall of the inner box body is symmetrically fixedly connected to two fixing columns, and an inclined guide plate is slidably connected to the two fixing columns together, and one end of the inclined guide plate away from the filter plate is set as an inclined surface.

[0013] Preferably, the outer walls of the two fixing columns are sleeved with a return spring, and the two ends of the return spring are respectively fixedly connected to the corresponding fixing column and the inclined guide plate.

[0014] The agricultural solid waste contaminated soil remediation device provided by the present invention has the following beneficial effects: By vibrating the soil on the filter plate, the soil leaks out from the filter holes on the filter plate, while the building concrete stones that are larger than the filter holes will not fall and stay on the filter plate, thereby screening out the residual solid waste in the soil. It can effectively remove the concrete stones embedded in the soil, reduce the obstruction of the stones when the repair fluid is subsequently injected, and allow the repair fluid to fully penetrate into the soil.

[0015] The soil is first broken up by the crushing blade, then scooped up by the bucket, and the filter plate is used to screen and remove concrete stones. The screened soil will fall to the ground after the shoveled soil. The soil broken up by the crushing blade can break the long-term compacted soil structure. The soil contaminated by construction solid waste tends to become compacted due to the pressure and accumulation of construction waste. The breaking up operation is conducive to expanding the soil pores, which is conducive to the exchange and storage of air, water and nutrients in the soil, so that the aeration of the soil is significantly improved.

[0016] By allowing the rectangular frame slide bar to no longer limit the limit plate, the support shaft cannot maintain balance, and the gravity of the stones on the filter plate will press the filter plate to rotate downward, and the filtered stones can be dumped into the collection frame, thereby achieving the effect of quickly collecting stones and allowing the screening component to maintain a continuous stone screening effect.

[0017] The rotation of the rotating disk can intermittently drive the conical tube to be inserted into the soil to inject liquid medicine to repair the soil. Compared with the traditional method of just spraying liquid medicine on the surface of soil contaminated by solid waste, the insertion injection of repair liquid medicine can inject medicine into the deeper layer of soil embedded with stones. The alkaline soil caused by lime pollution in the fixed waste of construction can be effectively neutralized by injecting liquid medicine, thereby improving the soil repair effect. In addition, the intermittent injection of liquid medicine can achieve the effect of rational injection and avoid waste caused by continuous drug spraying.

[0018] The closer the T-tube is to the ground, the deeper the height of the conical tube driven by the subsequent L-shaped rod will be; the farther the T-tube is from the ground, the shallower the height of the conical tube driven by the subsequent L-shaped rod will be. Since liquid pollutants may penetrate into deeper soil layers with rainwater, the repair liquid can be accurately delivered to the polluted area by injecting the repair liquid into the soil at different depths, so that the repair liquid and the pollutants can fully contact and react at the corresponding depth.

[0019] Furthermore, when the rack rod moves up and down, it will also drive multiple convex columns fixed on its upper end to move up and down synchronously, so that the multiple convex columns will drive the multi-angle cam to rotate at one time, and the multi-angle cam will drive the long shaft and the stirring blades to rotate, so as to stir the liquid in the storage box, avoid the restoration liquid from settling in the storage box and stratify, and prevent the concentration of the sprayed liquid from being different, resulting in inconsistent progress of soil restoration.

[0026] See also Figure 3 Two fixing columns 52 are symmetrically fixedly connected to the outer wall of the inner box body 26, and an inclined guide plate 51 is slidably connected to the two fixing columns 52. The end of the inclined guide plate 51 away from the filter plate 28 is set as an inclined surface. The outer walls of the two fixing columns 52 are both sleeved with return springs 53, and the two ends of the return spring 53 are respectively fixedly connected to the corresponding fixing columns 52 and the inclined guide plate 51.

[0027] The following is the entire working process of the above embodiment: Initial state: Initially, the two buckets 24 on the outer wall of the rotating shaft 23 are in a horizontal state, so there is a gap between them and the ground, and they are not in contact with the ground. The multiple crushing blades 7 on the rotating roller 6 are not located directly below the rotating roller 6, so there is also a gap between them and the ground, and they are not in contact with the ground. In this way, the user can use the handrails on the base plate 1 and the electric wheels to move the storage box 2 until it moves to the position where the soil needs to be repaired.

[0028] When working, first pour the liquid medicine and water required for soil remediation from the liquid inlet pipe on the storage box 2 in proportion, then insert the sealing plug to seal the storage box 2. When the entire device is located on the land to be remediated, the motor 1 5 and the motor 2 22 can be started. The motor 1 5 drives the rotating roller 6 and the crushing blade 7 to rotate. When the crushing blade 7 rotates, it will be inserted into the soil and crush the soil. The rotation of the motor 2 22 will drive the rotating shaft 23 to rotate counterclockwise. At this time, the electric wheel at the bottom of the base plate 1 is also in the on state, and the user holds the handrail to make the entire device in a slow walking state. , the rotating shaft 23 drives the bucket 24 to rotate counterclockwise synchronously, so that the bucket 24 scoops up the scattered soil, and as the bucket 24 rotates counterclockwise toward the inner box 26, the scooped soil can be thrown into the inner box 26, and when the rotating shaft 23 rotates, it will also drive the rotating disk 214 to rotate counterclockwise synchronously through the chain 215. When the rotating disk 214 rotates, the three tooth groups 217 on its outer surface will intermittently engage the rack rod 216, and when engaged, it will drive the rack rod 216 to move upward, so that the rack rod 216 drives the rectangular frame slide bar 212 fixed at its bottom to slide upward, and compress The external spring 213 will also drive the limit plate 210 inside it to move upward synchronously when the rectangular frame slide bar 212 moves upward, and drive the inner box body 26, the support shaft 27 and the filter plate 28 to move upward synchronously. When one of the tooth groups 217 on the rotating disk 214 is not engaged with the rack rod 216, the rectangular frame slide bar 212, the inner box body 26, the support shaft 27 and the filter plate 28 will be pushed downward by the reset action of the external spring 213. As the rotating disk 214 continues to rotate, the inner box body 26, the support shaft 27 and the filter plate 28 can be reversed. The filter plate 28 is repeatedly moved up and down to vibrate the soil on the filter plate 28, so that the soil is filtered through the filter holes on the filter plate 28, while the building concrete stones that are larger than the filter holes will not fall and stay on the filter plate 28, thereby screening the residual solid waste in the soil. The concrete stones embedded in the soil can be effectively removed, and the obstruction of the stones can be reduced when the repair liquid is subsequently injected, so that the repair liquid can fully penetrate into the soil. It can also prevent the seeds of crops planted after the subsequent soil repair from being planted on the remaining concrete stones, thereby affecting the germination rate of the seeds.

[0029] It should be noted that the specific steps are to first break up the soil with the crushing blade 7, then scoop up the soil with the bucket 24, and use the filter plate 28 to screen and remove concrete stones, and the screened soil will fall to the ground after the soil is shoveled, and breaking up the soil with the crushing blade 7 can break up the long-term compacted soil structure. The soil contaminated by construction solid waste will often become compacted due to the pressure and accumulation of construction waste. The breaking up operation is conducive to expanding the soil pores, which is conducive to the exchange and storage of air, water and nutrients in the soil, so that the aeration of the soil is significantly improved.

[0030] Furthermore, when the two buckets 24 rotate counterclockwise to throw the soil toward the inner box 26, a portion of the soil will fall on the inclined guide plate 51. The inclined guide plate 51 is inclined, and can guide the soil that falls from the bucket 24 due to gravity back into the inner box 26. When the bucket 24 rotates close to the inclined guide plate 51, since one end of the inclined guide plate 51 is set as an inclined surface, the bucket 24 will squeeze the inclined guide plate 51 to slide on the outer wall of the fixed column 52 toward the inner box 26, and gradually compress the return spring 53, so that the bucket 24 can rotate smoothly, thereby ensuring that the shoveled soil will fall on the filter plate 28 for screening as much as possible.

[0031] Furthermore, when it is necessary to collect the screened stones, a collection frame can be placed at the bottom of the inner box 26 first, and then the user pulls the sleeve 29 sleeved on the outside of the support shaft 27 on both sides of the isolation plate 25, and pulls the built-in spring 211 to stretch. When the sleeve 29 is pulled toward the side away from the inner box 26, it will also synchronously drive the limit plate 210 to gradually move away from the rectangular frame slide bar 212, so that the rectangular frame slide bar 212 no longer limits the limit plate 210. At this time, the support shaft 27 cannot maintain balance, and the gravity of the stones on the filter plate 28 will press the filter plate 28 to rotate downward, so that the filtered stones can be dumped into the collection frame, thereby achieving the effect of quickly collecting stones, and allowing the screening component to maintain a continuous stone screening effect.

[0032] Furthermore, during the rotation of the rotating disk 214, the connecting rod 31 connected thereto will also be driven to rotate synchronously. When the rotating disk 214 drives the hinge point with the connecting rod 31 to rotate to the bottom, the connecting rod 31 will move downward and rotate accordingly, and will also synchronously drive the L-shaped rod 32 to slide downward on the limit frame 33. The L-shaped rods 32 on both sides will drive the commonly fixed liquid outlet pipe 2 34 to slide downward in the liquid outlet pipe 1 3 and stretch the auxiliary spring 311. At this time, the auxiliary spring 311 is fixed to the inner wall of the liquid outlet pipe 2 34. The sealing column 37 will also move down synchronously. Since the sealing column 37 is composed of a conical column and a cylindrical column, and both are made of rubber, when the liquid outlet pipe 2 34 moves down, the conical column will not be sealed with the sealing plate 38, and the cylindrical column will still be located in the sealing plate 38. At this time, the liquid in the storage box 2 will first pass through the liquid outlet pipe 1 3, and then flow out in small amounts from the gap between the sealing plate 38 and the cylindrical column in the liquid outlet pipe 1 3. Due to the effect of the cylindrical column on the sealing column 37, the liquid will flow down slowly. For details, please refer to Fig. 9 and Fig.10 When the connecting rod 31 drives the L-shaped rod 32 and the second liquid outlet pipe 34 to descend to the bottom, the cylindrical column on the sealing column 37 will completely pass through the sealing plate 38, and the second liquid outlet pipe 34 drives the T-shaped tube 35 and the conical tube 36 to be inserted into the soil. At this time, the repair liquid will flow out into the soil through the leakage holes on the second liquid outlet pipe 34, the T-shaped tube 35 and the conical tube 36, thereby achieving the effect of injecting the repair liquid into the soil. The continuous rotation of the rotating disk 214 will move upward again through the connecting rod 31, and the second liquid outlet pipe 34 will be driven upward again through the reset of the L-shaped rod 32 and the auxiliary spring 311. At this time, the sealing column 37 will also move upward again and gradually push the sealing plate 38 in. The conical tube 36 is sealed during the plugging process, and a small amount of liquid medicine will flow out during the process and drip onto the soil surface through the leakage hole on the conical tube 36. Therefore, the rotation of the rotating disk 214 can intermittently drive the conical tube 36 to be inserted into the soil to inject liquid medicine to repair the soil. Compared with the traditional method of just spraying liquid medicine on the soil surface contaminated by solid waste, the insertion injection of repair liquid medicine can inject medicine into the deeper layer of the soil embedded with stones. For the alkalinized soil caused by lime pollution in the construction solid waste, the injection of liquid medicine can effectively neutralize it, thereby improving the soil repair effect. In addition, the intermittent injection of liquid medicine can achieve the effect of rational injection and avoid waste caused by continuous drug spraying.

[0033] In addition, the insertion depth of the conical tube 36 can be adjusted according to actual needs. Specifically, the bolt 310 can be removed from the screw hole 39 on one of the T-tubes 35 by rotating it, and then the T-tube 35 is adjusted up and down according to the scale line on the T-tube 35, and then the bolt 310 is inserted into the corresponding screw hole 39 on the T-tube 35 to fix the height of the T-tube 35. Specifically, the closer the T-tube 35 is to the ground, the deeper the height of the conical tube 36 driven by the subsequent L-shaped rod 32 is lowered, and the farther the T-tube 35 is from the ground, the shallower the height of the conical tube 36 driven by the subsequent L-shaped rod 32 is lowered. Since liquid pollutants may penetrate into deeper soil layers with rainwater, the repair liquid can be accurately transported to the polluted area by injecting the repair liquid into the soil at different depths, so that the repair liquid and the pollutants are fully in contact and react at the corresponding depth.

[0034] It should be noted that when the rotating disk 214 rotates one circle, it will drive the L-shaped rod 32 to move up and down once through the connecting rod 31, but it will engage the rack rod 216 with its three sets of tooth groups 217 on the outside to vibrate up and down multiple times, so as to achieve the effect of intermittently inserting the soil to inject the liquid medicine, but maintain a faster vibration amplitude to screen the stones.

[0035] Furthermore, when the rack rod 216 moves up and down, it will also drive multiple bosses 44 fixed on its upper end to move up and down synchronously, so that the multiple bosses 44 will drive the polygonal cam 43 to rotate at one time, and the polygonal cam 43 will drive the long shaft 41 and the stirring blade 42 to rotate, so as to stir the liquid in the storage box 2, avoid the restoration liquid from settling in the storage box 2 and stratify, and prevent the concentration of the sprayed liquid from being different, resulting in inconsistent progress of soil restoration.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
