Technical Field

[0001] The present invention relates to the technical field of soil remediation, in particular to a soil remediation device for ecological environment protection. Background Art

[0002] Soil remediation refers to technical measures to restore the normal function of polluted soil. The main purpose of soil remediation is to protect and improve soil quality so that it can maintain good ecological functions and agricultural production capacity. Through remediation, soil erosion and water loss can be prevented, soil pollution can be reduced, and biodiversity and ecological balance can be protected. At the same time, the remediated soil can improve agricultural production capacity, improve soil structure, increase soil fertility, and improve soil water retention and air permeability. In addition, soil remediation also helps to protect water resources, prevent land degradation, and achieve sustainable development and ecological balance.

[0003] The method of soil repair is generally to drill a hole down to a certain depth from the soil surface, and then inject a soil repair agent into the hole to achieve the purpose of repair.

Compared with the traditional method of directly injecting the repair agent, the loss of the soil repair agent can be reduced, further saving costs. At the same time, since the present invention has the function of preventing hole collapse, the opening angle of the drill barrel can be adjusted according to actual conditions. For example, the opening angle of the drill barrel can be inclined, which is more conducive to soil repair. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-Figure 11 , the present invention provides a technical solution:

[0038] A soil remediation device for ecological environment protection includes a drill tube 1, a driving component 2, a suspension seat 3 and a reagent tube 4, wherein the reagent tube 4 is coaxially fixedly connected to the drill tube 1, more specifically, part of the reagent tube 4 is coaxially fixedly connected to the drill tube 1, the driving component 2 is used to drive the drill tube 1 to rotate at a predetermined speed, and the actual rotation speed of the drill tube 1 can be adjusted according to the actual soil conditions, which is not limited here, and the suspension seat 3 is used to facilitate the fixed connection of the drill tube 1 with the suspension device, so as to use the suspension device to suspend and move the entire soil remediation device to a suitable position. The structure and working principle of these four parts are described in detail below.

[0039] A drill tooth 12 is fixed to the bottom end of the drill barrel 1, and an inner spiral piece 13 is fixedly connected between the inner bottom of the drill barrel 1 and the bottom of the reagent tube 4; the drill barrel 1 is made of metal material, such as stainless steel. Since the drill tooth 12 is mainly used for cutting soil, the material of the drill tooth 12 can be the same as that of the drill barrel 1, or it can be made of other cemented carbide materials, and there is no specific limitation on this; the inner spiral piece 13 can rotate with the drill barrel 1, so as to crush the soil entering the drill barrel 1 and reduce the particle size of the blocky soil.

[0040] A medicine spraying nozzle 44 is provided at the bottom of the medicine tube 4 and above the inner spiral blade 13, and the medicine spraying nozzle 44 extends outward along the radial direction of the medicine tube 4; it can be seen from the figure that there are two medicine spraying nozzles 44, which are respectively arranged on both sides of the medicine tube 4, and the medicine spraying nozzle 44 is used to spray the soil remediation agent into the interior of the drill barrel 1 and mix it with the soil located inside the drill barrel 1 and crushed by the inner spiral blade 13, and then cooperate with the stirring and mixing action of the medicine spraying nozzle 44 to achieve uniform mixing of the soil remediation agent and the soil.

[0041] An outer spiral blade 16 is fixed to the outer peripheral surface of the main cylinder body 11; the outer spiral blade 16 can cut the soil in contact with the outer wall of the drill tube 1 to loosen the soil, so that after the drill tube 1 is screwed out, the mixture of the soil remediation agent and the soil core column inside it can be better combined with the external soil, that is, a buffer layer is provided for the slow diffusion of the remediation agent.

[0042] In the above scheme, by means of the drill tube 1 and the drill teeth 12, when drilling a hole in soft soil, the soil core column cut by the drill teeth 12 can be retained in the drill tube 1, and at the same time, the inner spiral blade 13 can crush the soil core column during drilling to reduce the particle size of the soil block, and then the crushed soil core column is stirred in cooperation with the chemical tube 4 and the spray nozzle 44, and at the same time, the soil remediation agent is sprayed into the soil core column through the chemical tube 4 and the spray nozzle 44, so that the soil remediation agent and the soil core column are fully stirred and mixed in the drill tube 1, and then the drill tube 1 is slowly unscrewed from the entire soil, and the mixture of the soil remediation agent and the soil core column is directly retained in the drilled hole. During the whole process, the drill tube 1 is located inside the soil, playing a role in supporting the hole wall and preventing collapse, and After the drill tube 1 is screwed out, the mixture of the soil remediation agent and the soil core column is directly retained in the drilled hole, continuing to support the hole wall and prevent collapse, ensuring the feasibility of drilling repair in flexible soil, reducing the cost and difficulty of soil repair, and the above mixture has the function of preserving the repair agent, so that the soil remediation agent in the mixture can be gradually diffused into the soil adjacent to it by slow release. Compared with the traditional method of directly injecting the repair agent, the loss of the soil remediation agent can be reduced, further saving costs. At the same time, since the present invention has the function of preventing hole collapse, the opening angle of the drill tube 1 can be adjusted according to actual conditions. For example, the opening angle of the drill tube 1 can be inclined, which is more conducive to soil repair.

[0043] The structure of the medicine spray nozzle 44 will be described in detail below.

[0044] The spray nozzle 44 includes an output pipe 443 connected to the medicine pipe 4, a connecting column 447 coaxially fixed to the output pipe 443, and a fixing sleeve 4471 coaxially sleeved on the outside of the connecting column 447. The fixing sleeve 4471 is fixedly connected to the inner surface of the drill pipe 1. The connecting column 447 and the fixing sleeve 4471 cooperate to prevent the output pipe 443 from bending and deformation, thereby enhancing the anti-bending performance of the output pipe 443.

[0045] Further, as shown in the figure, the spray nozzle 44 also includes a connecting pipe 441 fixedly connected to the medicine pipe 4, a second mechanical seal 442 for making the connecting pipe 441 and the output pipe 443 coaxially rotate and seal, a flat hollow piece 444 fixedly connected to the output pipe 443, and a flat hose 445 fixedly connected to the flat hollow piece 444. The connecting column 447 can rotate coaxially in the fixed sleeve 4471; the flat hollow piece 444 is formed with an inclined surface 4441 at one end away from the output pipe 443, and the flat hose 445 is provided with a shrinking oblique piece 446 at a position corresponding to the inclined surface 4441, and a sealing hook 4461 is provided at the bottom of the end of the shrinking oblique piece 446 away from the output pipe 443. The sealing hook 4461 is made of the same material as the shrinking oblique piece 446 and the flat hose 445, and the three are integrally formed.

[0046] Furthermore, a ring-shaped member 448 is fixed to one end of the second mechanical seal 442 away from the medicine tube 4, a stopping groove 4481 is provided at the bottom of the ring-shaped member 448, and a stopping block 449 is fixed to the side of the output tube 443. The stopping block 449 can rotate inside the stopping groove 4481, thereby limiting the maximum rotation angle of the flat hollow member 444.

[0047] The working principle of the medicine spraying nozzle 44 is as follows: after the drill tube 1 has drilled a hole for a certain period of time, when the medicine spraying nozzle 44 is located at a certain depth inside the soil core column inside the drill tube 1, the soil remediation agent is transported to the inside of the medicine tube 4 through the pump, and then passes through the connecting pipe 441, the output pipe 443, and the flat hollow part 444 in sequence, and then the shrinking inclined piece 446 is opened and sprayed into the soil core column; the clockwise rotation of the drill tube 1 is recorded as drilling a hole in the soil, and the counterclockwise rotation is recorded as rotating out of the soil; when the drill tube 1 rotates clockwise or counterclockwise, under the limiting cooperation of the annular part 448, the stop groove 4481 and the stop block 449, the inclination directions of the flat hollow part 444 and the flat hose 445 are exactly opposite (for example, when the drill tube 1 rotates clockwise, the inclination directions of the flat hollow part 444 and the flat hose 445 are as follows: Figure 5 As shown, when the drill tube 1 rotates counterclockwise, the inclination direction of the flat hollow member 444 and the flat hose 445 should be consistent with Figure 5 The purpose of such design is to prevent the spray nozzle 44 from being blocked. At the same time, the flat hose 445 has a wider outlet so that the soil remediation agent can be sprayed into the soil core column more evenly and over a large area. Moreover, since the flat hollow part 444 is kept in an inclined state, the stirring of the soil core column is faster and more uniform, thereby improving work efficiency.

[0048] The drill barrel 1 includes a main barrel body 11 and a thickened barrel 14 arranged on the top of the main barrel body 11. The wall thickness of the main barrel body 11 and the thickened barrel 14 is basically the same, but the inner diameter of the thickened barrel 14 is larger than the inner diameter of the main barrel body 11. A through opening 141 is opened on the peripheral wall of the thickened barrel 14, and a shovel plate 15 extending into the inside of the thickened barrel 14 is installed inside the through opening 141. The inner end of the shovel plate 15 (that is, the end close to the axis of the thickened barrel 14) is between the inner wall of the thickened barrel 14 and the inner wall of the main barrel body 11, that is, the inner end of the shovel plate 15 does not extend to the top of the inner peripheral wall of the main barrel body 11. The purpose of such limitation is to prevent the inner end of the shovel plate 15 from causing a limit blockage to the movable part 45 described below, so that the movable part 45 can be smoothly moved up to the top of the thickened barrel 14.

[0049] The reagent tube 4 includes a main tube 41 and a secondary tube 42 rotatably connected to the top of the main tube 41 through a first mechanical seal 43; a conical head 411 is fixed to the bottom end of the main tube 41, and the setting of the conical head 411 is conducive to drilling into the soil; a movable part 45 that can slide along its axial direction is provided on the main tube 41, and the movable part 45 has a first conical surface 451 and a second conical surface 452, and the maximum diameter of the movable part 45 is slightly smaller than the inner diameter of the main cylinder 11.

[0050] The working principle of the cooperation between the thickened tube 14 and the movable member 45 is as follows: as the drill tube 1 gradually penetrates into the soil, the height of the soil core column inside the drill tube 1 becomes higher and higher, and the height of the movable member 45 will gradually increase under the push of the soil core column. Fig.11 When in the state shown (that is, the highest position), the movable part 45 cannot continue to rise. At this time, the top of the soil core column will be squeezed into the inside of the thickening cylinder 14 under the action of the first conical surface 451 of the movable part 45. Since the thickening cylinder 14 and the main cylinder body 11 rotate synchronously at this time, the soil entering the inside of the thickening cylinder 14 will be shoveled to the outside of the thickening cylinder 14 by the rotating shovel plate 15 through the opening 141, avoiding excessive soil inside the drill tube 1 to affect the mixing process; the role of the second conical surface 452 is to prevent soil from accumulating on the top of the movable part 45.

[0051] The driving component 2 includes a three-phase reduction motor 21, a housing 22 and a transmission structure; the housing 22 is rotatably connected to the top of the drill barrel 1, the three-phase reduction motor 21 is installed on the top of the housing 22, and the three-phase reduction motor 21 is transmission-connected to the drill barrel 1 through the transmission structure; the transmission structure includes a first gear 23 and a second gear 24 that are meshed and connected, and the first gear 23 and the second gear 24 are both arranged inside the housing 22, the first gear 23 is fixedly connected to the output shaft of the three-phase reduction motor 21, and the second gear 24 is sleeved and fixed on the top of the drill barrel 1.

[0052] The suspension seat 3 includes a suspension plate 31 and a plurality of connecting rods 32 , and the suspension plate 31 is fixedly connected to the housing 22 via the connecting rods 32 .

[0053] 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.
