Description

Technical Field

[0001] The present invention relates to the technical field of soil treatment, and in particular to a contaminated soil treatment device and a soil treatment method thereof. Background Art

[0002] Due to the rapid population growth and industrial development, solid waste is constantly piled and dumped on the soil surface, harmful wastewater is constantly infiltrating into the soil, and harmful gases and dust in the atmosphere are constantly falling into the soil with rain, leading to soil pollution. Any substance that hinders the normal function of the soil, reduces crop yield and quality, and indirectly affects human health through food, vegetables, fruits, etc. is called soil pollutants. Land management refers to the process of applying engineering measures and biological measures to improve the adverse properties of land, improve land utilization and productivity, and facilitate intensive management. The integrity of the land determines the comprehensiveness of land management measures.

[0003] The commonly used methods for treating contaminated soil are to excavate the contaminated soil and pile it on the ground, then filter the accumulated contaminated soil for debris and spray and mix it with soil remediation agents, and then fill the treated soil to a designated position on the ground again. When in use, the remediation efficiency of the contaminated soil is low, and the soil can only be excavated, sprayed with agents, cleaned with debris or filled with soil. When in use, when the volume of the soil is large, the sprayed soil remediation agent cannot be well mixed with the soil, resulting in the large volume of soil being unable to contact the soil remediation agent. The commonly used contaminated soil treatment equipment cannot achieve a good crushing effect on the soil when in use. Summary of the invention

[0008] Preferably, both ends of the opposing surfaces of the two buckets near the edge are provided with mutually fitting fixing grooves, and the middle ends of the opposing surfaces of the two buckets near the edge are provided with mutually fitting grooves, and limiting holes are provided on the inner walls of the grooves. The interior of the grooves is connected with the interior of the placement grooves through the limiting holes, and second support blocks are installed at both ends of the sides of the two buckets near the opposing surfaces, and the two ends of the second support blocks are respectively rotatably installed in the fixing grooves on the two buckets.

[0009] Preferably, a first support block is installed on the side surfaces of the two buckets near the opposite surfaces, and the two ends of the first support block are rotatably installed in the grooves on the two buckets respectively. A connecting block is installed on the side of the first support block, and the connecting block is located inside the limiting hole, and the end of the connecting block away from the first support block is located inside the placement groove, and the end of the second electric telescopic arm located inside the placement groove is connected to the connecting block.

[0010] Preferably, a mounting shaft is rotatably mounted on the inner wall of the two buckets, a mounting sleeve is mounted on the outer wall of the mounting shaft, a plurality of stirring rods are mounted on the outer wall of the mounting sleeve, and two ends of the mounting sleeve are respectively abutted against the inner walls of both sides of the bucket.

[0011] Preferably, a protective groove is opened on the side of the mounting block, a motor is installed inside the protective groove, one end of the motor is installed on the side of the bucket, one end of the mounting shaft passes through the bucket and is connected to the output shaft of the motor through a coupling.

[0012] Preferably, a fixed slide rail is installed on the side of the two buckets at one end of the first electric telescopic arm away from the mounting block, the electric sliders on the two first electric telescopic arms are respectively slidably installed on the two ends of the fixed slide rail, a fixed plate is installed on the middle end of the fixed slide rail away from the bucket, and a mounting seat that cooperates with the second electric telescopic arm is installed on the middle end of the fixed slide rail close to the bucket.

[0013] Preferably, both ends of the two buckets away from the opposite surface are provided with limit grooves, the two limit grooves are respectively located on both sides of the motor, and a convex limit plate is slidably installed on the outer wall of the first electric telescopic arm, and the limit plate is slidably installed inside the limit groove.

[0014] Preferably, a plurality of fixing holes are opened on the top of the mounting plate, and a plurality of threaded rods matching the fixing holes are installed on the side of the support plate close to the mounting plate. The end of the threaded rod away from the support plate passes through the fixing holes and is threadedly installed with an internal thread block, and a storage cavity is provided inside the support plate.

[0015] A method for using a contaminated soil treatment device in the present invention comprises the following steps:

[0016] Step 1: The staff threadedly installs the first electric telescopic arm on the end of the mounting block on the two buckets away from the discharge hole, and installs the fixing plate on the designated mobile vehicle. When in use, the mobile vehicle pulls the two buckets to move on the ground of the designated contaminated soil through the fixing plate, the fixed slide rail and the first electric telescopic arm. The downward pressure of the bucket on the ground causes the soil on the ground to enter the interior of the two buckets as the bucket moves;

[0017] Step 2: The output shaft of the motor drives the installation shaft inside the bucket to rotate, and the installation shaft enables a number of stirring rods to stir and crush the soil inside the bucket through the installation sleeve. As the bucket moves, the external soil is squeezed into the bucket and the stirring rods are moved, so that the crushed soil is discharged from the outside through a number of discharge holes, while larger debris accumulates inside the bucket, which is convenient for filtering and cleaning the debris;

[0018] Step 3: The staff installs support plates at the bottom of the two mounting plates located above the sides of the two buckets. The support plates support and limit the positions of the two buckets through the mounting plates at both ends. The connectors at both ends of the support plates are connected to the external agent delivery pipes. When the crushed soil moves out of the bucket through the discharge hole, the several spray ports at the bottom of the support plates spray the agent on the soil surface.

[0019] Step 4: The staff installs the first electric telescopic arm at one end of the mounting block close to the discharge hole, so that the mobile vehicle pushes the bucket toward the accumulated soil or shovels on the ground. When the mobile vehicle pushes the bucket to move, the mobile vehicle can compact the soil discharged from the bucket to the ground, so that the staff can fill the position where the soil is dug out on the ground;

[0020] Step 5: One end of the second electric telescopic arm is connected to the mounting seat. When the soil inside the bucket is discharged through the discharge hole, the staff disassembles the support plate. The second electric telescopic arm pulls the two buckets close to one end of the opposite surface, so that the two buckets rotate around the first support block. When in use, the two buckets can protect and store the debris inside to prevent the debris inside the bucket from falling to the outside. At the same time, the two buckets can clamp larger debris from the outside when rotating, which is convenient for carrying and cleaning the debris.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, the staff installs the fixed slide rail on the rear end or front end of the designated mobile vehicle through the fixed plate. The position where the fixed plate is installed on the mobile vehicle is different, and the methods used by the two buckets for spraying and purifying the contaminated soil with drugs will also be different. When the fixed plate is installed at the rear end of the mobile vehicle, the soil after the fusion of the drug can fall to the position where the contaminated soil on the ground is excavated. When in use, the position where the contaminated soil on the ground is excavated can be automatically filled evenly. When the fixed plate is installed at the front end of the mobile vehicle, the mobile vehicle can compact the soil covering the ground when moving, so as to prevent the treated soil from being too loosely covered on the ground after being crushed by the stirring rod, and soil loss will occur when it rains. When in use, there is no need for the staff to fill and compact the soil afterwards.

[0023] 2. In the present invention, when the staff needs to clean and carry the debris inside the soil, the fixed plate is installed at the front end of the mobile vehicle, the first electric telescopic arm can be connected to the fixed block on the side of the bucket, and the second electric telescopic arm pulls the first support block through the connecting block. When in use, the two buckets can rotate around the first support block, and the two electric sliders slide on the fixed slide rail to drive the two first electric telescopic arms to move their positions. When in use, the first electric telescopic arm and the second electric telescopic arm cooperate with each other to make the two buckets rotate around the first support block to clamp the debris on the outside ground, and the clamped debris is located inside the two buckets. When in use, the bucket can better protect the debris inside the bucket to prevent the debris inside the bucket from falling during transportation and cleaning.

[0024] 3. In the present invention, after the contaminated soil enters the interior of the bucket, a plurality of stirring rods can stir and crush the soil entering the bucket, and the sprayable agent can be better mixed with the soil to improve the purification effect of the contaminated soil. When in use, the squeezing force of the external soil on the crushed soil and the stirring force on the crushed soil when the stirring rod rotates can make the crushed contaminated soil discharged from the bucket through a plurality of discharge holes on the inner wall of the bucket. When in use, the crushed contaminated soil can be automatically discharged from the bucket as the bucket moves and the external soil is squeezed, which is more convenient to use.

[0025] 4. In the present invention, the staff installs the support plate at the bottom of the upper mounting plate on the side of the bucket close to the discharge hole. The support plate is installed above the side of the bucket, which makes it more convenient for the staff to spray the agent into the soil and facilitates the contact and fusion of the agent and the soil. When in use, the two ends of the support plate are respectively connected to the mounting plates on the two buckets, so that the support plate can better connect and fix the side of the two buckets away from the first electric telescopic arm through the two mounting plates when in use, making the two buckets more stable when moving and preventing the two buckets from rotating when in use.

[0045] As a technical optimization solution of the present invention, a plurality of fixing holes 22 are opened on the top of the mounting plate 5, and a plurality of threaded rods 30 matching the fixing holes 22 are installed on the side of the support plate 14 close to the mounting plate 5. The end of the threaded rod 30 away from the support plate 14 passes through the fixing hole 22 and is threadedly installed with an internal thread block 31. A storage cavity is provided inside the support plate 14. When in use, the staff can install and disassemble the support plate 14 at any time according to the usage, so that the support plate 14 can not only support and connect the two buckets 1, but also be used for spraying medicines, while preventing the support plate 14 located below from affecting the movement of the bucket 1.

[0046] A method for using a contaminated soil treatment device in the present invention comprises the following steps:

[0047] Step 1: The staff threadably installs the first electric telescopic arm 2 on the ends of the mounting blocks 3 on the two buckets 1 away from the discharge hole 11, and installs the fixing plate 8 on the designated mobile vehicle. When in use, the mobile vehicle pulls the two buckets 1 on the ground of the designated contaminated soil through the fixing plate 8, the fixed slide rail 6 and the first electric telescopic arm 2, and the soil on the ground enters the interior of the two buckets 1 as the buckets 1 move downwardly through the buckets 1.

[0048] Step 2: The output shaft of the motor 10 drives the mounting shaft 29 inside the bucket 1 to rotate, and the mounting shaft 29 enables a plurality of stirring rods 13 to stir and crush the soil inside the bucket 1 through the mounting sleeve 12. As the bucket 1 moves, the external soil is squeezed into the bucket 1 and the stirring rods 13 are moved, so that the crushed soil is discharged to the outside through a plurality of discharge holes 11, and larger debris is accumulated inside the bucket 1, which is convenient for filtering and cleaning the debris;

[0049] Step 3: The staff installs the support plate 14 at the bottom of the two mounting plates 5 located at the upper side of the two buckets 1. The support plate 14 supports and defines the positions of the two buckets 1 through the mounting plates 5 at both ends. The connectors 15 at both ends of the support plate 14 are connected to the external agent delivery pipe. When the crushed soil moves out of the bucket 1 through the discharge hole 11, the several spray ports 16 at the bottom of the support plate 14 spray the agent on the soil surface.

[0050] Step 4: The staff installs the first electric telescopic arm 2 on one end of the mounting block 3 close to the discharge hole 11, so that the mobile vehicle pushes the bucket 1 to the accumulated soil or to shovel on the ground. When the mobile vehicle pushes the bucket 1 to move, the mobile vehicle can compact the soil discharged from the bucket 1 to the ground, so that the staff can fill the position where the soil is dug out on the ground;

[0051] Step 5: One end of the second electric telescopic arm 17 is connected to the mounting seat 27. When the soil inside the bucket 1 is discharged through the discharge hole 11, the staff disassembles the support plate 14. The second electric telescopic arm 17 pulls the two ends of the buckets 1 close to the opposite surface, so that the two buckets 1 rotate around the first support block 19. When in use, the two buckets 1 can protect and store the debris inside them to prevent the debris inside the bucket 1 from falling to the outside. At the same time, the two buckets 1 can clamp larger debris from the outside when rotating, which is convenient for carrying and cleaning the debris.

[0052] When the present invention is in use, the staff installs the two first electric telescopic arms 2 at one end of the mounting block 3 on the opposite surface of the two buckets 1, and the first electric telescopic arms 2 are located in the direction of the mounting block 3 away from the discharge hole 11. When in use, the staff slides the electric sliders 7 on the two first electric telescopic arms 2 on both ends of the fixed slide rail 6. The staff installs the fixed slide rail 6 at the rear end of the designated mobile vehicle through the fixed plate 8, and the staff can remove the fixed plate 8 at any time according to the use situation. The staff installs the support plate 14 at the bottom of the upper mounting plate 5 on the side of the bucket 1 close to the discharge hole 11. When in use, the support plate 14 is installed above the side of the bucket 1 to prevent the support plate 14 from affecting the movement of the bucket 1 when in use, and also prevent the ground and the support plate 14 from rubbing against each other when the bucket 1 moves, resulting in damage to the support plate 14. The support plate 14 is installed above the side of the bucket 1, which makes it more convenient for the staff to spray the agent into the soil. When in use, the two ends of the support plate 14 are respectively connected to the mounting plates 5 on the two buckets 1, so that the support plate 14 can better connect and fix the two buckets 1 on the side away from the first electric telescopic arm 2 through the two mounting plates 5, making the two buckets 1 more stable when moving and preventing the two buckets 1 from rotating when in use.

[0053] When in use, the connectors 15 at both ends of the top of the support plate 14 are interconnected with the external agent delivery pipe, and a storage cavity is provided inside the support plate 14. When in use, the external agent solution for soil treatment can be delivered to the storage cavity inside the support plate 14 through the delivery pipe, and the storage cavity can store the agent for a short time. However, after the staff has installed the first electric telescopic arm 2 and the support plate 14, the staff can start the mobile vehicle, and drive the fixed slide rail 6 to move through the mobile vehicle and the fixed plate 8, and the fixed slide rail 6 can move by pulling the two buckets 1 through the two first electric telescopic arms 2. When in use, the buckets 1 slide on the ground, and the bottom ends of the two buckets 1 located below the mounting block 3 are located inside the ground soil. When the two buckets 1 move, the soil on the ground can enter the interior of the two buckets 1. When in use, the contaminated soil to be treated can be placed inside the buckets 1 for treatment. When there is less contaminated soil on the ground, there is no need for workers to dig and pile up the contaminated soil. When in use, the contaminated soil on the ground can be directly removed, crushed, and sprayed with chemicals, and then covered again at the location where the contaminated soil was excavated. When in use, the efficiency of contaminated soil purification treatment can be improved.

[0054] When the contaminated soil enters the bucket 1, the staff can start the motor 10, and the output shaft of the motor 10 drives the installation shaft 29 located inside the bucket 1 to rotate, and the installation shaft 29 can drive the installation sleeve 12 and several stirring rods 13 thereon to rotate when rotating. When in use, several stirring rods 13 can stir and crush the soil entering the bucket 1, and the sprayable agent can be better mixed with the soil to improve the purification effect of the contaminated soil. When the bucket 1 moves, the contaminated soil from the outside will continue to enter the bucket 1 and squeeze the contaminated soil that has been crushed inside the bucket 1. When in use, the squeezing force of the outside soil on the crushed soil and the movement of the stirring rod 13 on the crushed soil can make the crushed contaminated soil discharged from the bucket 1 through several discharge holes 11 on the inner wall of the bucket 1. When in use, the crushed contaminated soil can be automatically discharged from the bucket 1 with the movement of the bucket 1 and the squeezing of the outside soil, which is more convenient to use.

[0055] When the crushed contaminated soil is moved out of the bucket 1 through the discharge hole 11, the plurality of spray ports 16 located at the bottom of the support plate 14 can spray the agent stored in the storage cavity inside the support plate 14 onto the surface of the crushed contaminated soil. When in use, the soil purification agent can be integrated with the crushed contaminated soil, and the soil integrated with the agent can fall to the position where the contaminated soil is excavated on the ground. When in use, the position where the contaminated soil is excavated on the ground can be automatically filled evenly, which is more convenient to use.

[0056] During use, the staff can adjust the installation position of the first electric telescopic arm 2. After disassembling the first electric telescopic arm 2, the staff installs the first electric telescopic arm 2 in the screw hole 28 at one end of the mounting block 3 close to the discharge hole 11. At the same time, the staff installs the fixing plate 8 at the front end of the mobile vehicle, and the staff installs one end of the second electric telescopic arm 17 located inside the placement groove 18 on the mounting seat 27 on the fixed slide rail 6, and the other end is installed on the connecting block 21 on the side of the first support block 19. When the mobile vehicle moves, it can push the two buckets 1 to move on the opposite side to form a shovel shape. When in use, the two buckets 1 can shovel the contaminated soil on the ground. After the contaminated soil is crushed by the stirring rod 13 and the support plate 14 and sprayed with chemicals and covered on the ground, the soil covering the opposite side can be compacted as the mobile vehicle moves to prevent the treated soil from being too loose after being crushed by the stirring rod 13 and covered on the ground, resulting in soil loss when it rains. When in use, the treated soil can be filled and buried in real time, and the filled soil can be compacted at the same time. There is no need for staff to fill and compact the soil afterwards, which is more convenient to use.

[0057] When the staff needs to clean and move the debris inside the soil, the staff can disassemble the support plate 14 and install the ends of the two first electric telescopic arms 2 close to the mounting block 3 in the connecting grooves 33 on the fixed blocks 32 on the sides of the two buckets 1 respectively. When in use, the staff can insert the connecting rod 34 into the connecting hole on the first electric telescopic arm 2, and then install the connecting rod 34 on the inner wall of the connecting groove 33 again.

When in use, the mobile vehicle pulls the two buckets (1) to move on the ground of designated contaminated soil through the fixing plate (8), the fixed slide rail (6) and the first electric telescopic arm (2). The downward pressure of the buckets (1) on the ground causes the soil on the ground to enter the interior of the two buckets (1) as the buckets (1) move. Step 2: The output shaft of the motor (10) drives the mounting shaft (29) inside the bucket (1) to rotate, and the mounting shaft (29) causes a plurality of stirring rods (13) to stir and crush the soil inside the bucket (1) through the mounting sleeve (12). As the bucket (1) moves, the external soil is squeezed into the bucket (1) and the stirring rods (13) are moved, so that the crushed soil is discharged from the outside through the plurality of discharge holes (11), while larger debris accumulates inside the bucket (1), making it easy to filter and clean the debris; Step 3: The staff installs a support plate (14) at the bottom of the two mounting plates (5) located above the sides of the two buckets (1). The support plate (14) supports and defines the positions of the two buckets (1) through the mounting plates (5) at both ends thereof. The connectors (15) at both ends of the support plate (14) are connected to an external agent delivery pipe. When the crushed soil is moved out of the bucket (1) through the discharge hole (11), a plurality of spray ports (16) at the bottom of the support plate (14) spray the agent on the soil surface. Step 4: The staff installs the first electric telescopic arm (2) at one end of the mounting block (3) close to the discharge hole (11), so that the mobile vehicle pushes the bucket (1) toward the accumulated soil or shovels on the ground. When the mobile vehicle pushes the bucket (1) to move, the mobile vehicle can compact the soil discharged from the bucket (1) to the ground, so that the staff can fill the position where the soil is dug out on the ground; Step 5: One end of the second electric telescopic arm (17) is connected to the mounting seat (27). When the soil inside the bucket (1) is discharged through the discharge hole (11), the staff disassembles the support plate (14). The second electric telescopic arm (17) pulls the two buckets (1) close to one end of the opposite surface, so that the two buckets (1) rotate around the first support block (19). When in use, the two buckets (1) can protect and store the debris inside them to prevent the debris inside the buckets (1) from falling to the outside. At the same time, the two buckets (1) can clamp larger debris outside when rotating, which is convenient for carrying and cleaning the debris.
