Description

Technical Field

[0001] The present invention relates to the field of soil remediation, and in particular to a soil remediation system and a remediation process. Background Art

[0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. In the soil remediation industry, there are more than 100 existing soil remediation technologies and more than 10 commonly used technologies, which can be roughly divided into three processes: physical, chemical and biological. Since the 1980s, many countries in the world, especially developed countries, have formulated and implemented contaminated soil treatment and remediation plans, thus forming an emerging soil remediation industry.

[0003] In the process of soil remediation, most of them rely on machines with relatively complete functions. However, for some economically backward areas, since they cannot afford the expensive machine purchase and use costs, they still use manual loosening of the soil and manual spraying of remediation agents. In the process of loosening the soil, some sticky soils are easy to adhere to the shovel, which increases the workload of workers. Summary of the invention

[0004] The object of the present invention is to provide a soil remediation system and a remediation process to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A soil remediation system, comprising:

[0007] A frame, wherein two through slots are symmetrically arranged on the frame, and a loosening structure which can be raised and lowered and can pass through one of the through slots is arranged on the frame, and the loosening structure cooperates with a plurality of abutments arranged on the frame to separate the soil adhering to the loosening structure from the loosening structure. A trigger assembly is also arranged on the frame, and the trigger assembly is connected to the loosening structure to drive the loosening structure to rise and fall in a direction perpendicular to the frame. The trigger assembly is also connected to a pouring assembly arranged on the frame, and the pouring assembly is used to evenly spread the soil remediation agent on the loosened soil.

[0008] As a further solution of the present invention: the loosening structure includes a loosening member connected to the trigger assembly, a plurality of blades are equidistantly arranged on the loosening member, and a plurality of through holes for the resisting member to pass through are opened on the loosening member between two blades.

[0009] As a further solution of the present invention: the trigger assembly includes a mounting frame fixedly mounted on the frame, the mounting frame is provided with a wire transmission structure and two sets of energy storage structures connected to the loose parts, the wire transmission structure is provided with two pulleys, and the pulleys cooperate with abutment plates provided on the energy storage structure.

[0010] As a further solution of the present invention: the linear transmission structure includes two transmission wheels symmetrically mounted on the mounting frame, a transmission chain is provided on the two transmission wheels, and one of the transmission wheels is connected to the output shaft of the driving device fixedly rotating on the mounting frame, and the transmission chain is rotationally connected to the pulley.

[0011] As a further solution of the present invention: the energy storage structure includes a cross bar installed on the mounting frame, a sliding sleeve is slidably arranged on the cross bar, the sliding sleeve is fixedly connected to the abutment plate, a spring is sleeved on the cross bar, one end of the spring is connected to the mounting frame, and the other end is connected to the sliding sleeve, a connecting rod is rotatably installed on the sliding sleeve, one end of the connecting rod is away from the sliding sleeve and is rotatably connected to a pulling plate arranged on the mounting frame, the pulling plate is slidably installed on a guide plate fixed to the mounting frame, and the pulling plate is fixedly connected to the loosening part.

[0012] As a further solution of the present invention: the pouring assembly includes a material storage box fixedly connected to the frame through a connecting frame, and a stirring rod connected to another driving wheel through a first belt is rotatably installed in the material storage box;

[0013] It also includes an oscillating structure connected to the transmission wheel.

[0014] As a further solution of the present invention: the oscillation structure includes a feeding hopper rotatably arranged on the frame, the feeding hopper is used to receive the soil remediation agent dropped from the storage box, and the feeding hopper is abutted against a plurality of cams arranged on the connecting frame, the rotating shaft of the cam is connected to a bevel gear set arranged on the connecting frame, and the bevel gear set is connected to the rotating shaft of the transmission wheel through a No. 2 belt.

[0015] A process for repairing soil using the soil repair system comprises the following steps:

[0016] Step 1: transporting the soil remediation system to the soil to be remediated;

[0017] Step 2: Control the frame to move and control the linear transmission structure to work. The linear transmission structure cooperates with the energy storage structure to store energy in the energy storage structure and drive the loosening structure to quickly insert into the soil. The loosening structure is driven again by the linear transmission structure to rise. In the process of the loosening structure rising, it cooperates with the resisting member to separate the soil adhering to the loosening structure from the loosening structure.

[0018] Step 3: During the operation of the online transmission structure, the pouring component is driven to work, the soil remediation agent is stirred, and the agent is evenly spread on the loosened soil;

[0019] Step 4: After repairing the soil in a straight line, change the position of the frame and repeat steps 1 to 3 to complete the repair of the soil.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The trigger component that is set can drive the loosening structure to rise and fall periodically to loosen the soil, so that when the soil remediation agent is poured, the agent can penetrate deeply into the soil for a more thorough remediation. At the same time, during the lifting and lowering process of the loosening structure, it can cooperate with the resistance parts to separate the soil adhering to the loosening structure from the loosening structure, thereby greatly improving the working efficiency of the loosening structure. At the same time, after the soil is loosened, the pouring component evenly spreads the soil remediation agent on the loosened soil, so that the soil to be repaired is evenly covered with the remediation agent, thereby achieving more comprehensive soil remediation.

DETAILED DESCRIPTION

[0031] 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.

[0032] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0033] See also Figures 1 to 8 In an embodiment of the present invention, a soil remediation system includes:

[0034] A frame 1, wherein two through slots 27 are symmetrically arranged on the frame 1, and a loosening structure which can be raised and lowered and can pass through one of the through slots 27 is arranged on the frame 1, and the loosening structure includes a loosening member 14, and a plurality of blades 15 are equidistantly arranged on the loosening member 14, and a plurality of through holes are opened on the loosening member 14 between the two blades 15, and the through holes cooperate with a plurality of abutment members 17 arranged on the frame 1, and the abutment members 17 are used to separate the soil adhering between the two blades 15 from the blades 15.

[0035] During the loosening process, the loosening member 14 drives multiple blades 15 to rise and fall in a direction perpendicular to the frame 1, and inserts into the soil during the descent. The rear blade 15 rises and drives the soil adhered between two adjacent blades 15. When the blades 15 rise to a certain height, the abutment member 17 passes through the through hole, abuts against the soil adhered between the two blades 15, and separates the soil from the blades 15, thereby completing the loosening action.

[0036] Exemplarily, a detachable connection is adopted between the blade 15 and the loose part 14, which can be a bolt and nut connection or a snap connection, and the distance between two adjacent blades 15 is adjustable to adapt to soils of different viscosities, that is, when the viscosity of the soil to be repaired is relatively large, the distance between the two adjacent blades 15 can be increased, and when the viscosity of the soil to be repaired is relatively small, the distance between the two adjacent blades 15 can be appropriately shortened, and the size of the distance is based on the fact that when the blade 15 rises, the two adjacent blades 15 can bring up the soil.

[0037] See also Figure 2 , Figure 3 , Figure 4 , the loosening member 14 is connected to a trigger assembly arranged on the frame 1, the trigger assembly is used to drive the loosening member 14 to rise and fall in a direction perpendicular to the frame 1, the trigger assembly includes a mounting frame 2 fixedly mounted on the frame 1, a wire transmission structure and two sets of energy storage structures connected to the loosening member 14 are arranged on the mounting frame 2, two pulleys 6 are arranged on the wire transmission structure, the pulleys 6 cooperate with the abutment plates 9 arranged on the energy storage structures, and the mounting frame 2 is connected to the abutment member 17 through a fixing member 16;

[0038] The linear transmission structure comprises two transmission wheels 4 symmetrically rotatably mounted on the mounting frame 2, a transmission chain 5 is sleeved on the two transmission wheels 4, and one of the transmission wheels 4 is connected to the output shaft of the driving device 3 fixedly rotated on the mounting frame 2, and the transmission chain 5 is rotatably connected to the pulley 6;

[0039] The energy storage structure includes a cross bar 7 mounted on the mounting frame 2, a sliding sleeve 8 is slidably provided on the cross bar 7, the sliding sleeve 8 is fixedly connected to the abutment plate 9, a spring 10 is sleeved on the cross bar 7, one end of the spring 10 is connected to the mounting frame 2, and the other end is connected to the sliding sleeve 8;

[0040] A connecting rod 11 is rotatably mounted on the sliding sleeve 8, and one end of the connecting rod 11 away from the sliding sleeve 8 is rotatably connected to a pulling plate 12 arranged on the mounting frame 2. The pulling plate 12 is slidably mounted on a guide plate 13 fixed to the mounting frame 2, and the pulling plate 12 is fixedly connected to the loosening member 14.

[0041] When in use, the driving device 3 is controlled to work, driving the transmission wheel 4 connected thereto to rotate, and a transmission chain 5 is sleeved between the two transmission wheels 4, so that the transmission chain 5 moves accordingly and causes the two pulleys 6 arranged on the transmission chain 5 to move, wherein the two pulleys 6 are arranged diagonally on the transmission chain 5, and when one of the pulleys 6 abuts against one of the abutment plates 9, the other pulley 6 abuts against the other abutment plate 9, and with the movement of the transmission chain 5, the sliding sleeve 8 can be driven to move on the cross bar 7 through the pulley 6 and the abutment plate 9, and while compressing the spring 10, the sliding sleeve 8 drives the pulling plate 12 to move upward through the connecting rod 11, and the pulling plate 12 is slidably arranged on the guide plate 13, so that in the process of its ascent, the stability is better , and since the transmission chain 5 is a closed double-layer structure, when the pulley 6 moves to the circumferential end of the transmission chain 5, it will gradually disengage from the abutment plate 9, and after the two are disengaged, the spring 10 releases the elastic potential energy, drives the sliding sleeve 8 to move in the opposite direction on the cross bar 7, and drives the loosening piece 14 to move downward quickly, and drives the blade 15 to insert into the soil. Similarly, since the transmission chain 5 is a double-layer closed structure, the two pulleys 6 can alternately abut and separate from the two abutment plates 9, thereby realizing the rapid lifting and lowering of the blade 15 to complete the loosening action. Through the above-mentioned arrangement, the blade 15 is inserted into the soil more quickly, and after the blade 15 is inserted into the soil, it is immediately pulled up to avoid long-term contact with the soil, thereby reducing the resistance of the frame 1 during movement.

[0042] See also Figure 6 , Figure 7 , Figure 8 The transmission wheel 4 is also connected to a pouring assembly arranged on the frame 1, and the pouring assembly is used to evenly spread the soil remediation agent on the loosened soil. The pouring assembly includes a storage box 19 fixedly connected to the frame 1 through a connecting frame 26, and a stirring rod 20 connected to another transmission wheel 4 through a No. 1 belt 18 is rotatably installed in the storage box 19;

[0043] The pouring assembly also includes an oscillating structure connected to the transmission wheel 4, and the oscillating structure includes a feeding hopper 24 rotatably arranged on the frame 1, and the feeding hopper 24 is used to receive the soil remediation agent dropped from the storage box 19, and the feeding hopper 24 abuts against a plurality of cams 23 arranged on the connecting frame 26;

[0044] The rotating shaft of the cam 23 is connected to the bevel gear set 22 arranged on the connecting frame 26, and the bevel gear set 22 is connected to the rotating shaft of the transmission wheel 4 through the second belt 21;

[0045] Wherein, a plurality of diamond-shaped pieces 25 are equidistantly arranged on the feeding hopper 24, so that the repair agent can be poured more evenly.

[0046] During the lifting and lowering process of the blade 15, the rotating shaft of the transmission wheel 4 drives the stirring rod 20 connected thereto to rotate through the No. 1 belt 18 to stir the soil remediation agent in the storage box 19. On the one hand, this can make the mixing degree of the soil remediation agent higher, avoiding the poor soil remediation effect in the local area due to the incomplete mixing of the drug components in the remediation agent. On the other hand, through the rotation of the stirring rod 20, the remediation agent is prevented from accumulating at the discharge port of the storage box 19 and causing the discharge port of the storage box 19 to be blocked.

[0047] At the same time, during the rotation of the stirring rod 20, the transmission wheel 4 drives the cam 23 to rotate through the No. 2 belt 21 and the bevel gear set 22, and the cam 23 is in a state of abutment with the feeding hopper 24, thereby causing the feeding hopper 24 to vibrate and pass the soil remediation agent through another through groove 27 and spread it on the loosened soil to complete the soil remediation.

[0048] The bevel gear set 22 includes a first bevel gear and a second bevel gear rotatably mounted on the connecting frame 26 and meshing with each other. The first bevel gear is coaxially fixedly connected to the rotating shaft of the cam 23 , and the second bevel gear is connected to the second belt 21 .

[0049] As an embodiment of the present invention, a process for repairing soil using the soil repair system is also proposed, comprising the following steps:

[0050] Step 1: transporting the soil remediation system to the soil to be remediated;

[0051] Step 2: Control the frame 1 to move and control the linear transmission structure to work. The linear transmission structure cooperates with the energy storage structure to store energy in the energy storage structure and drive the loosening structure to quickly insert into the soil. The linear transmission structure drives the loosening structure to rise again. In the process of the loosening structure rising, the loosening structure cooperates with the abutment 17 to separate the soil adhering to the loosening structure from the loosening structure.

[0052] Step 3: During the operation of the online transmission structure, the pouring component is driven to work, the soil remediation agent is stirred, and the agent is evenly spread on the loosened soil;

[0053] Step 4: After repairing the soil on a straight line, change the position of the frame 1 and repeat the above steps 1 to 3 to complete the repair of the soil.

[0054] In summary, when in use, the driving device 3 is controlled to work, so as to drive the transmission wheel 4 connected thereto to rotate, and a transmission chain 5 is sleeved between the two transmission wheels 4, so that the transmission chain 5 moves accordingly and causes the two pulleys 6 arranged on the transmission chain 5 to move, wherein the two pulleys 6 are arranged diagonally on the transmission chain 5, and when one of the pulleys 6 abuts against one of the abutment plates 9, the other pulley 6 abuts against the other abutment plate 9, and with the movement of the transmission chain 5, the sliding sleeve 8 can be driven to move on the cross bar 7 through the pulley 6 and the abutment plate 9, and while compressing the spring 10, the sliding sleeve 8 drives the pulling plate 12 to move upward through the connecting rod 11, and the pulling plate 12 is slidably arranged on the guide plate 13, so that during its ascent, the pulling plate 12 is stably The transmission chain 5 has a closed double-layer structure, and when the pulley 6 moves to the circumferential end of the transmission chain 5, it will gradually separate from the abutment plate 9. After the two separate, the spring 10 releases the elastic potential energy, drives the sliding sleeve 8 to move in the opposite direction on the cross bar 7, and drives the loosening member 14 to move downward quickly, and drives the blade 15 to insert into the soil. Similarly, since the transmission chain 5 has a double-layer closed structure, the two pulleys 6 can alternately abut and separate from the two abutment plates 9, thereby realizing the rapid lifting and lowering of the blade 15 to complete the loosening action. Through the above-mentioned arrangement, the blade 15 can be inserted into the soil more quickly, and after the blade 15 is inserted into the soil, it is immediately pulled up to avoid long-term contact with the soil, thereby reducing the resistance of the frame 1 during movement.

[0055] During the loosening process, the loosening member 14 drives the multiple blades 15 to rise and fall in a direction perpendicular to the frame 1, and is inserted into the soil during the descent process. The rear blade 15 rises and drives the soil adhering to two adjacent blades 15. When the blades 15 rise to a certain height, the abutting member 17 passes through the through hole and abuts against the soil adhering to the two blades 15, and separates the soil from the blades 15, thereby completing the loosening action.

[0056] During the lifting and lowering process of the blade 15, the rotating shaft of the transmission wheel 4 drives the stirring rod 20 connected thereto to rotate through the No. 1 belt 18 to stir the soil remediation agent in the storage box 19. On the one hand, this can make the mixing degree of the soil remediation agent higher, avoiding the poor soil remediation effect in the local area due to the incomplete mixing of the drug components in the remediation agent. On the other hand, the rotation of the stirring rod 20 avoids the accumulation of the remediation agent at the discharge port of the storage box 19, which causes the discharge port of the storage box 19 to be blocked;

[0057] At the same time, during the rotation of the stirring rod 20, the transmission wheel 4 drives the cam 23 to rotate through the No. 2 belt 21 and the bevel gear set 22, and the cam 23 is in a state of abutment with the feeding hopper 24, thereby causing the feeding hopper 24 to vibrate and pass the soil remediation agent through another through groove 27 and spread it on the loosened soil to complete the soil remediation.
