Description

Technical Field

[0001] The present invention belongs to the technical field of soil remediation, and particularly relates to a soil remediation agent spraying device for soil remediation. Background Art

[0002] Soil remediation is a technical measure to restore contaminated soil to its normal function. In the soil remediation industry, there are more than a hundred existing soil remediation technologies, which can be roughly divided into three methods: physical, chemical, and biological.

[0003] Currently, during soil remediation, generally, the remediation agent is sprayed onto the soil surface. In this way, the remediation agent is only on the soil surface, resulting in uneven mixing with the overall soil and poor remediation effect. In view of the above technical problems, the applicant has searched for some existing technologies to achieve full contact and mixing of the remediation liquid and the soil. For example, a soil remediation agent spraying device for soil remediation with the patent publication number CN114515748B. Its main technical means is that the remediation agent powder in the remediation barrel will naturally spill out from multiple sprinkling holes. Subsequently, as the remediation barrel continues to rotate, multiple soil-turning tips on the remediation barrel will rotate synchronously with the remediation barrel. As a result, the multiple soil-turning tips will turn the soil after sprinkling the remediation agent, thereby completing the turning treatment of the soil, so that the soil remediation agent sprayed by this device can be in uniform contact with the soil, thereby improving the remediation effect of the remediation agent. After the applicant's analysis, the disadvantages of this technical solution are as follows: The above solution improves the remediation effect by turning the soil to make the remediation agent and the soil in uniform contact and mixing. However, when the soil is in a moving state while being turned suddenly, spraying the remediation agent at this time can only ensure that some areas of the soil are in contact with the remediation agent, and it is impossible to ensure full contact and mixing of the soil and the remediation agent, which also leads to poor remediation effect. Summary of the Invention

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] As Figures 1-5 shown, a soil remediation agent spraying device for soil remediation includes a side plate 1, a sealing cover 2, a crawler belt 3 and a plow blade 4. The device further includes: A rotating cylinder 5 is rotatably installed between two side plates 1. The rotating cylinder 5 is located at the rear end in the moving direction of the plow blade 4. An earth shovel 6 is installed around the rotating cylinder 5. A sealing cover 8 is arranged inside the rotating cylinder 5. There is a fixed rod 51 inside the rotating cylinder 5. The fixed rod 51 is coaxial with the rotating cylinder 5. A number of first telescopic parts 81 are installed around the fixed rod 51. The output end of the first telescopic part 81 is provided with a sealing cover 8. The sealing cover 8 penetrates the rotating cylinder 5 and covers the opening end of the earth shovel 6. A liquid storage tank 9 is installed inside the rotating cylinder 5. The liquid storage tank 9 stores the soil remediation agent. The liquid storage tank 9 is connected to the sealing cover 8 through a conduit. A number of spray holes 82 are opened on the sealing cover 8. The liquid pumping pump in the liquid storage tank 9 pumps the soil remediation agent into the sealing cover 8 through the conduit and finally sprays it out from a number of spray holes 82 to be mixed with the soil.

[0018] When the embodiment is actually used, the crawler 3 is used to move the device, and the device can adapt to various terrains. When the device is moving, the plow blade 4 turns the soil, and the rotary drum 5 drives several shovels 6 to rotate. When the shovel 6 moves to the bottom of the rotary drum 5, the shovel 6 can scoop up the turned soil, and the soil is temporarily stored in the shovel 6. Then, the cover 8 is extended through the telescopic member 81, and the cover 8 seals the open end of the shovel 6. Then, the soil repair agent is pumped into the cover 8 through the conduit through the pump in the liquid storage tank 9, and the repair agent is sprayed into the shovel 6 from several spray holes 82 to contact and mix with the soil. Since the shovel 6 is in a rotating state at this time, the soil in the shovel 6 will be displaced and rolled, so that each area of ​​the soil can be contacted and mixed with the repair agent, thereby improving the repair effect; when the shovel 6 passes the highest point of the rotary drum 5 and slowly rotates downward, the cover 8 is retracted into the rotary drum 5 through the telescopic member 81, so that the shovel 6 drops the mixed soil to the bottom surface; By controlling the moving speed of the crawler 3 and the rotating speed of the drum 5, when the drum 5 rotates, the plurality of shovels 6 can continuously shovel up the soil on the ground, avoiding soil faults and ensuring that all the soil can be shoveled up; in this way, the soil on the ground can be divided into several portions, and each portion of the soil is contacted and mixed with the repair agent separately. Compared with directly spraying the repair agent on the soil, the repair agent can be fully contacted and mixed with the soil, thereby further improving the repair effect; at the same time, shoveling up the soil can break the soil stratification, so that different layers of soil can be contacted and mixed with the repair agent, thereby further improving the repair effect; The repair agent is mixed with the soil in a sealed state, which effectively prevents the repair agent from volatilizing in an atomized state when spraying, thereby making full use of the repair agent and improving the repair effect.

[0019] Furthermore, a driving member 61 is installed on the side of the earth-shoveling shovel 6 , a rotating shaft 62 is installed on the output end of the driving member 61 , the rotating shaft 62 extends into the earth-shoveling shovel 6 , and a plurality of stirring rods 63 are arranged on the periphery of the rotating shaft 62 .

[0020] A plurality of crushing knives 64 are disposed on the periphery of the rotating shaft 62 .

[0021] In actual application of this embodiment, when soil enters the shovel 6 and the cover 8 seals the shovel 6, the driving member 61 rotates the rotating shaft 62, so that the stirring rod 63 stirs the soil, so that the soil and the repair agent are further fully contacted and mixed, and the repair effect is further improved; at the same time, the crushing knife 64 breaks up the agglomerated soil and breaks the agglomerated soil into small soils, so that the soil and the repair agent are further fully contacted and mixed, and the repair effect is further improved.

[0022] like Figure 2 and Figure 3As shown, a sieve mesh 7 is rotatably installed between two side plates 1. The sieve mesh 7 is located at the rear end in the moving direction of the rotating drum 5. The sieve mesh 7 is inclined obliquely upward, and its inclined direction is opposite to the direction when the sieve mesh 7 moves.

[0023] In actual application of this embodiment, when the earth shovel 6 moves below the highest point of the rotating drum 5, the cover 8 is retracted into the rotating drum 5. At this time, the soil in the earth shovel 6 is thrown out by centrifugal force. The thrown soil hits the sieve mesh 7, so that the soil will be further broken. The broken soil is sieved by the sieve mesh 7 and then falls to the ground, which makes the soil loose, thereby improving the quality of the soil and further improving the repair effect. At the same time, the sieve mesh 7 can filter out gravel or weeds in the soil, thereby further improving the quality of the soil and further improving the repair effect. A structure for spraying a repair agent towards the sieve mesh 7 can be installed here, so that the soil is further broken and then contacts and mixes with the repair agent again, which can further improve the repair effect.

[0024] Further, a collecting net 71 is arranged at the bottom of the sieve mesh 7. The two ends of the collecting net 71 are respectively rotatably connected to the two side plates 1. A baffle 72 is arranged at the top of the sieve mesh 7.

[0025] A connecting plate 731 is connected between the two side plates 1. A vibrating member 73 is installed on the connecting plate 731 and contacts the side of the sieve mesh 7 opposite to the moving direction of the sieve mesh 7.

[0026] In actual application of this embodiment, the gravel or weeds sieved by the sieve mesh 7 slide down and gather in the collecting net 71, avoiding the gravel or weeds from falling to the ground again and mixing with the repaired soil. The baffle 72 can block the splashing soil or gravel, avoiding the splashing soil or gravel from hurting nearby people or objects. While the sieve mesh 7 is sieving the soil, the vibrating member 73 makes the sieve mesh 7 vibrate, which can improve the sieving effect of the sieve mesh 7 and effectively avoid the blockage of the sieve mesh 7.

[0027] As Figure 6 shown, a rotating rod 92 is rotatably installed in the liquid storage tank 9. A number of counterweight rods 93 are arranged on the periphery of the rotating rod 92, and the number of counterweight rods 93 are arranged side by side.

[0028] In one case of this embodiment, a liquid adding pipe 91 is installed on the liquid storage tank 9, and a repair agent can be added into the liquid storage tank 9 through the liquid adding pipe 91.

[0029] In practical application of this embodiment, the liquid storage tank 9 rotates with the rotating drum 5, and the repair agent in the liquid storage tank 9 will shake inside the liquid storage tank 9, which can effectively avoid the precipitation of the repair agent, thereby ensuring uniform distribution of the active ingredients in the repair agent and improving the repair effect of the repair agent. At the same time, under the action of centrifugal force, several counterweight rods 93 in the liquid storage tank 9 drive the rotating rod 92 to rotate, which can stir the repair agent in the liquid storage tank 9, further avoid the precipitation of the repair agent, further ensure the uniform distribution of the active ingredients in the repair agent, and further ensure the repair effect of the repair agent.

[0030] As Figure 1 and Figure 2 As shown, an air inflation assembly 10 is installed between the two side plates 1. The air inflation assembly 10 is located at the front end in the moving direction of the plow blade 4. The air inflation assembly 10 includes a mounting plate 101. The mounting plate 101 is fixed between the two side plates 1. A second telescopic member 102 is installed at the bottom of the mounting plate 101. The output end of the second telescopic member 102 is provided with a movable plate 103. Several inflation needles 104 are installed at the bottom of the movable plate 103. An air inflation pump 105 is installed on the movable plate 103. The air inflation pump 105 is connected to several inflation needles 104.

[0031] In practical application of this embodiment, the soil may be in a compacted and hardened state. At this time, if the soil is turned over by the plow blade 4, on the one hand, it may cause the plow blade 4 to be unable to turn over deep soil, and on the other hand, the stress on the plow blade 4 is relatively large and the plow blade 4 is easily damaged. At this time, before the plow blade 4 turns over the soil, the second telescopic member 102 drives the movable plate 103 and several inflation needles 104 to move downward and insert into the soil, and then high-pressure gas is filled into the soil through the air inflation pump 105 and the inflation needles 104 to aerate the inside of the soil. Through the instantaneous explosive force of the high-pressure gas, the soil bulges upward, thereby loosening the soil. In this way, the plow blade 4 is more relaxed when turning over the soil, and can turn over deep soil, and the turned soil is relatively fluffy, so that the soil can be in full contact and mixing with the repair agent when contacting the repair agent subsequently, thereby improving the repair effect.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
