Description

Technical Field

[0001] The present invention relates to the technical field of oil collection, and particularly relates to a collection device for a small amount of leaked oil at an oil production wellhead. Background Art

[0002] When oil leaks to the ground, it will form "spilled oil". The spilled oil forms a mixture with the soil on the ground. The volatile components of the oil entering the atmosphere will pollute the air; entering the water body with rainwater or water flow will pollute the water body. After the oil penetrates into the soil, if plants absorb the oil, it will damage the metabolic process of the plants, block the water and nutrients needed by the plants, and thus cause the plants to die, resulting in the destruction of vegetation. Moreover, the soil polluted by the spilled oil may lose its functions of farming and animal husbandry for several years or even decades.

[0003] When a small amount of oil leaks from an oil production wellhead, it is necessary to collect the oil. However, when collecting the oil, some soil will be collected together, which will bring inconvenience to the collection work. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: A collection device for a small amount of leaked oil at an oil production wellhead of the present invention includes:

[0005] A bottom plate, a universal wheel is fixedly connected to the bottom of the bottom plate, a folding shell is fixedly connected to the top of the bottom plate, a base is fixedly connected to the top of the folding shell, an extrusion component is fixedly connected to the inside of the base, an electric hydraulic cylinder is fixedly connected to the top of the bottom plate, an output end of the electric hydraulic cylinder is fixedly connected to a connecting shaft, and the top of the connecting shaft is fixedly connected to the bottom of the base;

The side of the collection component is fixedly connected to the inside of the base. A connecting pipe is fixedly connected to the side of the collection component, and a collection box is fixedly connected to one end of the connecting pipe away from the collection component;

[0007] The collecting component comprises a collecting shell, the side of the collecting shell is fixedly connected to the inner side of the base, the top of the collecting shell is fixedly connected to an air suction machine, the side of the collecting shell is fixedly connected to an exhaust pipe, the end of the exhaust pipe away from the collecting shell is fixedly connected to the connecting pipe, the inner wall of the collecting shell is fixedly connected to a mesh plate, the bottom of the mesh plate is fixedly connected to a telescopic rod, the end of the telescopic rod away from the mesh plate is fixedly connected to a cleaning mechanism, a second spring is sleeved on the telescopic rod, the top of the second spring is fixedly connected to the bottom of the mesh plate, the bottom of the second spring is fixedly connected to the cleaning mechanism, the bottom of the collecting shell is fixedly connected to an arc shell, and the sides of the arc shell are evenly provided with through holes; the output of the electric hydraulic cylinder The outlet end drives the base downward through the connecting shaft, so that the side of the arc shell is against the leaked oil, and at the same time, the vacuum fan is turned on, and the suction force generated by the vacuum fan causes the leaked oil to enter the collection box through the discharge pipe and the connecting pipe for collection. At the same time, when the leaked oil is collected, the soil mixed with the oil is prevented from entering the discharge pipe. A mesh plate is added to the inner wall of the collection shell to resist the soil entering the collection shell. At the same time, when the vacuum fan is used for suction, the suction force generated by the vacuum fan causes the cleaning mechanism to move upward in the inner cavity of the collection shell through the telescopic rod, so that the cleaning mechanism can clean the inner wall of the collection shell.

[0008] Preferably, the cleaning mechanism includes a circular plate, the top of which is fixedly connected to the bottom of the telescopic rod, and the side surfaces of the circular plate are evenly provided with clearance grooves, and the upper and lower sides of the circular plate are fixedly connected with scrapers, and the side surfaces of the scrapers are evenly provided with through holes; when the vacuum machine is working, the telescopic rod drives the circular plate to move upward in the inner cavity of the collecting shell through the suction force of the vacuum machine, and when the circular plate moves, it also drives the scraper to clean and scratch the inner wall of the collecting shell, thereby avoiding a large amount of soil adhering to the inner wall of the collecting shell when the leaked oil is collected, and then drying on the inner wall of the collecting shell, and at the same time, by evenly providing clearance grooves on the side surfaces of the circular plate, it is avoided to interfere with the speed of the oil passing through the collecting shell, and at the same time, when the vacuum machine stops working, the circular plate drives the scraper to clean the inner wall of the collecting shell through the stretching and resetting action of the second spring, thereby avoiding a large amount of oil and soil remaining on the inner wall of the collecting shell after the oil is collected.

[0009] Preferably, the extrusion component includes an extrusion housing, a circular tube is fixedly connected to the side of the extrusion housing, one end of the circular tube away from the extrusion housing is fixedly connected to the collection box, a motor is fixedly connected to the top of the extrusion housing, the output end of the motor is fixedly connected to the top of the rotating rod, a rotating mechanism is rotatably connected to the inside of the extrusion housing, and an opening mechanism is slidably connected to the side of the extrusion housing; when the collection component finishes collecting the leaked oil, since part of the original oil solution will soak into the soil, it is not convenient to collect. After collecting the oil leaked from the oil well, by turning on the motor, the output end of the motor rotates forward to drive the rotating mechanism to rotate in the inner cavity of the extrusion housing, so that the rotating mechanism squeezes the soil mixed with oil entering the inner cavity of the extrusion housing, thereby collecting the original oil solution remaining in the soil. At the same time, the oil extruded from the soil is transported to the collection box through the circular tube for collection. At the same time, after collecting a small amount of leaked oil around the oil production well, the motor can be reversed to eject the soil in the extrusion housing.

[0010] Preferably, the rotating mechanism includes a rotating rod, a connecting rod is fixedly connected to the side of the rotating rod, an extrusion block is fixedly connected to one end of the connecting rod away from the rotating rod, the number of the extrusion blocks is three, and the three extrusion blocks are evenly arranged with the rotating rod as the center. Square grooves are evenly formed on the side of the extrusion block. A connecting plate is fixedly connected to the bottom of the rotating rod, a guiding cylinder is fixedly connected to the bottom of the connecting plate, discharge grooves are evenly formed on the side of the guiding cylinder, a square plate is fixedly connected to the side of the guiding cylinder, the square plate is arranged crosswise with the extrusion block, a contact component is slidably connected to one end of the square plate away from the guiding cylinder, a rotating shaft is fixedly connected to the bottom of the connecting plate, and a threaded blade is fixedly connected to the side of the rotating shaft; by the forward rotation of the output end of the motor, the rotating rod is driven to rotate in the extrusion housing, so that the rotating shaft drives the threaded blade to rotate, thereby driving the soil to move and be fed into the guiding cylinder through the threaded blade, and then entering the extrusion housing through the discharge groove. At the same time, when the rotating rod rotates in the extrusion housing, the guiding cylinder drives the square plate to impact the soil entering the extrusion housing, so that the soil moves towards the inner wall of the extrusion housing. At the same time, when the rotating rod rotates, the extrusion block is driven to rotate in the extrusion housing through the connecting rod, so as to squeeze the soil, thereby extruding the oil soaked in the soil. After extrusion, the oil enters the circular tube through the filter plate and then flows into the collection box for collection work.

[0011] Preferably, the contact assembly includes a moving groove which is formed on the side surface of the square plate. A contact rod is slidably connected to the inner wall of the moving groove. One end of the contact rod away from the moving groove is fixedly connected with a contact block. A first spring is sleeved on the contact rod. One end of the first spring is fixedly connected with the contact block, and the other end of the first spring away from the contact block is fixedly connected with the inner wall of the moving groove;

[0012] Preferably, the opening mechanism includes an opening groove and a filter screen plate. The opening groove is formed on the side surface of the extrusion housing. A baffle is slidably connected to the inner wall of the opening groove. A guide rod is fixedly connected to the side surface of the baffle. A spring rod is fixedly connected to the inner wall of the opening groove. One end of the spring rod away from the opening groove is fixedly connected with the baffle. A triangular block is fixedly connected to the side of the baffle close to the filter screen plate. The side surface of the filter screen plate is fixedly connected to the inner side of the extrusion housing; After the soil is extruded, since the oil leaks into the soil, the soil structure is damaged. After the soil is extruded, after the oil immersed in the soil is extruded, the oil enters the collection box through the round pipe. Then, a modifier is added to the collection housing. Then, the motor rotates in reverse to drive the rotating shaft to rotate in the extrusion housing, so that the square plate and the extrusion block mix and stir the soil mixed with the modifier. At the same time, when the motor rotates in reverse, the square plate is driven to rotate by the rotating shaft. Since the shape of the triangular block is a right triangle, the contact block is in extrusion contact with the right-angle surface of the triangular block, so that the triangular block drives the baffle to move in the opening groove, so that the soil rotated and mixed by the square plate is thrown out through the gap generated by the baffle and the opening groove, so as to throw out the soil mixed with the modifier, so as to improve the soil into which the oil has entered and avoid secondary pollution of the soil. At the same time, when the contact block and the triangular block are continuously extruded, when the square plate drives the contact block to rotate, when the extrusion force between the inclined surface of the triangular block and the contact block is less than the tensile force of the spring rod, the contact block moves by the extrusion of the first spring, and the contact rod slides in the moving groove, so that the contact block disengages from the triangular block, and the baffle is reset in the opening groove by the tensile force of the spring rod. At the same time, since the square plate drives the contact block to contact and extrude the inclined surface of the triangular block when the motor rotates forward, the contact block and the triangular block are in contact, and the baffle will not be driven to move in the opening groove, so as to avoid the baffle from sliding when the soil is extruded.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The present invention is provided with a collecting component. The output end of the electric hydraulic cylinder drives the base to move downward through a connecting shaft, so that the side of the arc-shaped shell abuts against the leaked oil. At the same time, by turning on the air suction machine, the suction force generated by the air suction machine causes the leaked oil to enter the collecting box through the discharge pipe and the connecting pipe for collection. When collecting the leaked oil, it is avoided that the soil mixed with the oil enters the discharge pipe together. By adding a mesh plate to the inner wall of the collecting housing, the soil entering the collecting housing is blocked. At the same time, when the air suction machine performs the air suction operation, the suction force generated by the air suction machine causes the cleaning mechanism to move upward in the inner cavity of the collecting housing through the telescopic rod, so that the cleaning mechanism can clean the inner wall of the collecting housing.

[0015] 2. The present invention is provided with a cleaning mechanism. When the air suction machine works, the telescopic rod drives the round plate to move upward in the inner cavity of the collecting housing through the suction force of the air suction machine. When the round plate moves, it simultaneously drives the scraping plate to clean and scrape the inner wall of the collecting housing, thereby avoiding a large amount of soil adhering to the inner wall of the collecting housing when collecting the leaked oil and then drying and solidifying on the inner wall of the collecting housing. At the same time, by evenly arranging relief grooves on the side of the round plate, it is avoided to interfere with the speed of the oil passing through the collecting housing. When the air suction machine stops working, the round plate drives the scraping plate to clean the inner wall of the collecting housing through the stretching and resetting action of the second spring, thereby avoiding a large amount of oil and soil remaining in the inner wall of the collecting housing after collecting the oil.

[0016] 3. The present invention is provided with a rotating mechanism. By the forward rotation of the output end of the motor, the rotating rod is driven to rotate in the extrusion housing, so that the rotating shaft drives the threaded blade to rotate, thereby driving the soil to move upward in the guiding cylinder through the threaded blade and entering the extrusion housing through the discharge slot. At the same time, when the rotating rod rotates in the extrusion housing, the guiding cylinder drives the square plate to impact the soil entering the extrusion housing, so that the soil is moved towards the inner wall of the extrusion housing. When the rotating rod rotates, the connecting rod drives the extrusion block to rotate in the extrusion housing, so as to extrude the soil, and the oil immersed in the soil is extruded. After extrusion, the oil enters the round pipe through the filter mesh plate and then flows into the collecting box for collection.

[0017] 4. The present invention is provided with an extrusion block. By evenly arranging square grooves on the side of the extrusion block, when the extrusion block extrudes the soil in the extrusion housing, it can fully contact with the soil, thereby extruding and collecting the oil immersed in the soil.

At the same time, by turning on the vacuum fan 52, the suction force generated by the vacuum fan 52 allows the leaked oil to enter the collecting box 7 through the discharge pipe 53 and the connecting pipe 8 for collection. At the same time, when collecting the leaked oil, the soil mixed with the oil is prevented from entering the discharge pipe 53. By adding a mesh plate 54 to the inner wall of the collecting shell 51, the soil entering the collecting shell 51 is resisted. At the same time, when the vacuum fan 52 is used for suction, the suction force generated by the vacuum fan 52 allows the cleaning mechanism 56 to move upward in the inner cavity of the collecting shell 51 through the telescopic rod 55, so that the cleaning mechanism 56 can clean the inner wall of the collecting shell 51.

[0033] The cleaning mechanism 56 includes a circular plate 561, the top of which is fixedly connected to the bottom of the telescopic rod 55, and the side of the circular plate 561 is evenly provided with a clearance groove 562.

At the same time, the side of the circular plate 561 is evenly provided with a clearance groove 562 to avoid interfering with the speed of the oil passing through the collecting shell 51. At the same time, when the vacuum machine 52 stops working, the circular plate 561 is stretched and reset by the second spring 57, so that the circular plate 561 drives the scraper 563 to clean the inner wall of the collecting shell 51, thereby avoiding a large amount of oil and soil remaining in the inner wall of the collecting shell 51 after the oil is collected.

[0034] Embodiment 2, useFigures 5-8 The following is an explanation of a collection device for a small amount of leaked oil at an oil production wellhead of the present invention.

[0035] As Figures 5-8 shown, a collection device for a small amount of leaked oil at an oil production wellhead of the present invention is based on Example 1;

[0036] The extrusion component 6 includes an extrusion housing 61. A circular tube 62 is fixedly connected to the side of the extrusion housing 61. One end of the circular tube 62 away from the extrusion housing 61 is fixedly connected to the collection box 7. A motor 63 is fixedly connected to the top of the extrusion housing 61. The output end of the motor 63 is fixedly connected to the top of the rotating rod 641. A rotating mechanism 64 is rotatably connected to the inside of the extrusion housing 61. An opening mechanism 65 is slidably connected to the side of the extrusion housing 61. When the collection component 5 finishes collecting the leaked oil, since part of the original oil solution will penetrate into the soil, it is not convenient to collect. After collecting the leaked oil, by turning on the motor 63, the output end of the motor 63 rotates forward to drive the rotating mechanism 64 to rotate in the inner cavity of the extrusion housing 61, so that the rotating mechanism 64 extrudes the soil mixed with oil entering the inner cavity of the extrusion housing 61, thereby collecting the original oil solution remaining in the soil. At the same time, the oil extruded from the soil is transported to the collection box 7 through the circular tube 62 for collection. At the same time, after collecting a small amount of leaked oil around the oil production well, the motor 63 can be reversed, so that the soil in the extrusion housing 61 can be thrown out.

[0037] The rotating mechanism 64 includes a rotating rod 641. A connecting rod 642 is fixedly connected to the side of the rotating rod 641. One end of the connecting rod 642 away from the rotating rod 641 is fixedly connected with an extrusion block 643. The number of extrusion blocks 643 is three, and the three extrusion blocks 643 are evenly arranged around the rotating rod 641. Square grooves 644 are evenly formed on the side of the extrusion block 643. A connecting plate 645 is fixedly connected to the bottom of the rotating rod 641. A guiding cylinder 649 is fixedly connected to the bottom of the connecting plate 645. Discharge grooves 646 are evenly formed on the side of the guiding cylinder 649. A square plate 647 is fixedly connected to the side of the guiding cylinder 649. The square plate 647 and the extrusion block 643 are arranged crosswise. A contact component 648 is slidably connected to one end of the square plate 647 away from the guiding cylinder 649. A rotating shaft 6410 is fixedly connected to the bottom of the connecting plate 645. A threaded blade 6411 is fixedly connected to the side of the rotating shaft 6410; When the output end of the motor 63 rotates forward, the rotating rod 641 is driven to rotate in the extrusion housing 61, so that the rotating shaft 6410 drives the threaded blade 6411 to rotate, and the soil is driven by the threaded blade 6411 to move and be fed in the guiding cylinder 649, and then enters the extrusion housing 61 through the discharge groove 646. At the same time, when the rotating rod 641 rotates in the extrusion housing 61, the guiding cylinder 649 drives the square plate 647 to impact the soil entering the extrusion housing 61, so that the soil is moved towards the inner wall of the extrusion housing 61. At the same time, when the rotating rod 641 rotates, the extrusion block 643 is driven by the connecting rod 642 to rotate in the extrusion housing 61, so as to perform extrusion work on the soil, and the petroleum immersed in the soil is extruded. After extrusion, the petroleum enters the round tube 62 through the filter plate 655 and then flows into the collection box 7 for collection work.

[0038] The contact component 648 includes a moving groove 6481 formed on the side of the square plate 647. A contact rod 6482 is slidably connected to the inner wall of the moving groove 6481. A contact block 6283 is fixedly connected to one end of the contact rod 6482 away from the moving groove 6481. A first spring 6284 is sleeved on the contact rod 6482. One end of the first spring 6284 is fixedly connected to the contact block 6283, and the other end of the first spring 6284 away from the contact block 6283 is fixedly connected to the inner wall of the moving groove 6481;

[0039] The opening mechanism 65 includes an opening groove 651 and a filter screen plate 655. The opening groove 651 is opened on the side of the extrusion housing 61. A baffle 652 is slidably connected to the inner wall of the opening groove 651. A guide rod 653 is fixedly connected to the side of the baffle 652. A spring rod 654 is fixedly connected to the inner wall of the opening groove 651. One end of the spring rod 654 away from the opening groove 651 is fixedly connected to the baffle 652. A triangular block 656 is fixedly connected to the side of the baffle 652 close to the filter screen plate 655. The side of the filter screen plate 655 is fixedly connected to the inner side of the extrusion housing 61. After the soil is extruded, since the oil leaks into the soil, the soil structure is damaged. After the soil is extruded, after the oil immersed in the soil is extruded, the oil enters the collection box 7 through the round pipe 62. Then, a modifier is added to the collection housing 51. Then, the motor 63 rotates in reverse to drive the rotating shaft 6410 to rotate in the extrusion housing 61, so that the square plate 647 and the extrusion block 643 mix and stir the soil mixed with the modifier. At the same time, when the motor 63 rotates in reverse, the square plate 647 is driven to rotate through the rotating shaft 6410. Since the shape of the triangular block 656 is a right triangle, the contact block 6283 is in extrusion contact with the right-angle surface of the triangular block 656, so that the triangular block 656 drives the baffle 652 to move in the opening groove 651, so that the soil rotated and mixed by the square plate 647 is thrown out through the gap formed by the baffle 652 and the opening groove 651, so as to throw out the soil mixed with the modifier, so as to improve the soil into which the oil has entered and avoid secondary pollution of the soil. At the same time, when the contact block 6283 continuously extrudes the triangular block 656, when the extrusion force between the inclined surface of the triangular block 656 and the contact block 6283 is less than the tensile force of the spring rod 654 during the rotation of the contact block 6283 driven by the square plate 647, the contact block 6283 moves by the extrusion of the first spring 6284, and slides in the moving groove 6481 through the contact rod 6482, so that the contact block 6283 disengages from the triangular block 656, and the baffle 652 is reset in the opening groove 651 by the tensile force of the spring rod 654. At the same time, since the square plate 647 drives the contact block 6283 to be in contact and extrusion with the inclined surface of the triangular block 656 when the motor 63 rotates forward, the contact block 6283 is in contact with the triangular block 656 and does not drive the baffle 652 to move in the opening groove 651, thus avoiding the sliding of the baffle 652 during the soil extrusion work.

[0040] The specific working process is as follows:

[0041] During operation, the device is moved to the oil leakage site via the casters 2. After opening the electric hydraulic cylinder 9, the output end of the electric hydraulic cylinder 9 drives the base 4 to perform height adjustment work through the connecting pipe 8. At the same time, by opening the collection component 5, the collection component 5 collects the leaked oil. After collecting the leaked oil, the extrusion component 6 can be opened, so that the extrusion component 6 performs extrusion work on the soil where the oil has leaked, thereby collecting the oil immersed in the soil;

[0042] The output end of the electric hydraulic cylinder 9 drives the base 4 to move downward through the connecting shaft 10, so that the side of the arc shell 58 abuts against the leaked oil. At the same time, by opening the air suction machine 52, the suction force generated by the air suction machine 52 causes the leaked oil to enter the collection tank 7 through the discharge pipe 53 and the connecting pipe 8 for collection work. At the same time, when collecting the leaked oil, it is avoided that the soil mixed with the oil enters the discharge pipe 53 together. By adding a mesh plate 54 to the inner wall of the collection housing 51, the soil entering the collection housing 51 is blocked. At the same time, when the air suction machine 52 performs suction work, the suction force generated by the air suction machine 52 causes the cleaning mechanism 56 to move upward in the inner cavity of the collection housing 51 through the telescopic rod 55, so that the cleaning mechanism 56 can clean the inner wall of the collection housing 51;

[0043] When the air suction machine 52 is working, the telescopic rod 55 drives the circular plate 561 to move upward in the inner cavity of the collection housing 51 through the suction force of the air suction machine 52. When the circular plate 561 is moving, it simultaneously drives the scraping plate 563 to clean and scrape the inner wall of the collection housing 51, thereby avoiding a large amount of soil adhering to the inner wall of the collection housing 51 and then drying and solidifying on the inner wall of the collection housing 51 when collecting the leaked oil. At the same time, by evenly arranging relief grooves 562 on the side surface of the circular plate 561, the speed of the oil passing through the collection housing 51 is not interfered. At the same time, when the air suction machine 52 stops working, the circular plate 561 drives the scraping plate 563 to clean the inner wall of the collection housing 51 through the stretching and resetting action of the second spring 57, thereby avoiding a large amount of oil and soil remaining in the inner wall of the collection housing 51 after collecting the oil;

[0044] After the collection component 5 has completed the collection of the leaked oil, since some of the original oil will penetrate into the soil, making it inconvenient to collect. After collecting the leaked oil, by turning on the motor 63, the forward rotation of the output end of the motor 63 drives the rotating mechanism 64 to rotate in the inner cavity of the extrusion housing 61, so that the rotating mechanism 64 squeezes the soil mixed with oil entering the inner cavity of the extrusion housing 61, thereby collecting the original oil remaining in the soil. At the same time, the oil extruded from the soil is transported to the collection tank 7 through the round pipe 62 for collection. Also, after collecting a small amount of leaked oil around the oil well, the motor 63 can be reversed to eject the soil in the extrusion housing 61;

[0045] By the forward rotation of the output end of the motor 63, the rotating rod 641 is driven to rotate in the extrusion housing 61, so that the rotating shaft 6410 drives the threaded blade 6411 to rotate, thereby driving the soil to move and be fed in the guide cylinder 649 through the threaded blade 6411, and then entering the extrusion housing 61 through the discharge slot 646. At the same time, when the rotating rod 641 rotates in the extrusion housing 61, the square plate 647 is driven by the guide cylinder 649 to impact the soil entering the extrusion housing 61, so that the soil is moved towards the inner wall of the extrusion housing 61. At the same time, when the rotating rod 641 rotates, the extrusion block 643 is driven to rotate in the extrusion housing 61 through the connecting rod 642, so as to squeeze the soil, thereby extruding the oil immersed in the soil. After extrusion, the oil enters the round pipe 62 through the filter plate 655 and then flows into the collection tank 7 for collection work;

[0046] By evenly arranging square grooves 644 on the side surface of the extrusion block 643, when the extrusion block 643 squeezes the soil in the extrusion housing 61, it can fully contact the soil, thereby extruding and collecting the oil immersed in the soil;

[0047] After the soil is extruded, since oil leaks into the soil, the soil structure is damaged. After the soil is extruded, by squeezing out the oil immersed in the soil, the oil enters the collection box 7 through the round pipe 62. Then, a modifier is added to the collection housing 51. Then, the motor 63 rotates in reverse to drive the rotating shaft 6410 to rotate in the extrusion housing 61, so that the square plate 647 and the extrusion block 643 mix and stir the soil mixed with the modifier. At the same time, when the motor 63 rotates in reverse, the square plate 647 is driven to rotate through the rotating shaft 6410. Since the shape of the triangular block 656 is a right triangle, the contact block 6283 is in extrusion contact with the right-angle surface of the triangular block 656, so that the triangular block 656 drives the baffle 652 to move in the opening groove 651, so that the soil rotated and mixed by the square plate 647 is thrown out through the gap formed by the baffle 652 and the opening groove 651, so as to throw out the soil mixed with the modifier, so as to improve the soil into which oil has entered and avoid secondary pollution of the soil. At the same time, when the contact block 6283 and the triangular block 656 are continuously extruded, when the contact block 6283 is driven to rotate by the square plate 647 and the extrusion force between the inclined surface of the triangular block 656 and the contact block 6283 is less than the tensile force of the spring rod 654, the contact block 6283 moves by the extrusion of the first spring 6284, and the contact rod 6482 slides in the moving groove 6481, so that the contact block 6283 disengages from the triangular block 656, and the baffle 652 is reset in the opening groove 651 by the tensile force of the spring rod 654. At the same time, since the square plate 647 drives the contact block 6283 to contact and extrude the inclined surface of the triangular block 656 when the motor 63 rotates forward, the contact block 6283 contacts the triangular block 656 and does not drive the baffle 652 to move in the opening groove 651, thus avoiding the sliding of the baffle 652 when the soil is extruded.
