Description

Technical Field

[0001] The present invention relates to the technical field of soil remediation, and in particular to a soil turning device for soil pollution remediation. Background Art

[0002] Soil pollution remediation technology refers to the general term for technologies that use chemical, physical and biological technologies and methods to reduce the concentration of pollutants in the soil, fix soil pollutants, convert soil pollutants into low-toxic or non-toxic substances, and block the transfer pathways of soil pollutants in the ecosystem.

[0003] However, the current amount of soil remediation fluid used is still determined based on the staff's experience. Due to different soil textures, the amount of remediation fluid required is also different. For soils with high clay content, the amount of remediation fluid needs to be increased to ensure sufficient reaction of pollutants. For sandy soils, excessive application of remediation fluid will not only cause waste of resources, but may also cause secondary pollution due to enrichment of the remediation fluid, which has a greater impact on the quality of soil remediation.

[0017] 2. The present invention drives the rotating rod to rotate in a circle through a motor, so that the rotating rod drives multiple groups of rotary tillage blades to make circular motion around the axis of the rotating rod. When the rotary tillage blades contact the soil, as the rotating rod continues to rotate, the rotary tillage blades gradually insert into the soil, realizing the turning operation of the soil.

The rotating plate drives the buffer rod to move upward along the inner wall of the sleeve, and the buffer rod then drives the piston to move upward synchronously. At this time, the piston will stretch the spring A sleeved on the outer wall of the buffer rod. During the stretching process, the spring A can absorb and buffer part of the impact force received by the rotary tillage blades, thereby effectively avoiding the rotary tillage blades from being damaged due to instantaneous excessive resistance, ensuring that the soil remediation operation can be carried out stably and efficiently, extending the service life of the equipment, and improving the reliability and connectivity of the remediation liquid injection work.

[0018] 3. When the rotating rod of the present invention is rotated clockwise, the rotating rod will drive the rotating shaft to rotate synchronously through the torsion spring. At this time, the one-way bearing is in an idling state and gear B remains stationary. When the push rod drives the push plate to move, the push rod will synchronously drive the connecting rod to move, prompting the connecting rod to drive rack B to move in the direction close to the base. At this time, the one-way bearing is locked, and rack B will drive gear B to rotate counterclockwise, and gear B drives the rotating shaft to rotate. When the rotating shaft rotates, it will drive the gear ring to rotate synchronously, and the rotation of the gear ring drives the gear ring to rotate, and finally the rotation of the gear ring drives the sleeve to rotate, so that the rotary tillage blade rotates a certain angle. When the rotary tillage blade rotates to a more inclined angle with the cutting edge, its soil cutting force is enhanced, which can more effectively break the compacted soil into fine particles and make the soil particles more uniform, so that the repair fluid can more fully penetrate between the soil particles, thereby improving the utilization efficiency of the repair fluid and enhancing the repair effect on contaminated soil.

DETAILED DESCRIPTION

[0021] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See Figures 1 to 8 As shown, the present invention provides a soil turning device for soil pollution remediation, comprising a base 1, a liquid storage tank 2 being mounted on the top of the base 1, two sets of mounting brackets 6 being slidably mounted on one end of the base 1, a rotating rod 7 being rotatably mounted between the two sets of mounting brackets 6, a sleeve 10 being rotatably mounted on the outer wall of the rotating rod 7, a rotary tillage blade 11 being hingedly mounted on the bottom end of the sleeve 10, and a spraying assembly being mounted above the rotary tillage blade 11; A buffer mechanism 16 is provided inside the sleeve 10. The buffer mechanism 16 includes a buffer rod 1601 that slides inside the sleeve 10. A piston 1602 is installed on the top of the buffer rod 1601. A rotating plate 1603 is rotatably provided between the buffer rod 1601 and the rotary tiller blade 11. A spring A1604 is provided on the outer wall of the buffer rod 1601. It should be noted that when the device is used to repair heavy metal contaminated soil, the operator first moves the device to the designated soil remediation area, and then starts the motor 8 and the suction pump 15. After the motor 8 is turned on, the output shaft of the motor 8 drives the rotating rod 7 to rotate in a circle, and then the rotating rod 7 drives multiple groups of rotary tillage blades 11 to make circular motion around the axis of the rotating rod 7. When the rotary tillage blades 11 contact the soil, as the rotating rod 7 continues to rotate, the rotary tillage blades 11 are gradually inserted into the soil to realize the turning operation of the soil. Due to the difference in the compaction degree of the soil in different areas, the resistance experienced by the rotary tillage blades 11 during the operation is also the same. When the resistance encountered by the rotary tillage blades 11 reaches a certain threshold The rotary tillage blade 11 will rotate through the rotating plate 1603 under the reaction force of the soil. The rotating plate 1603 drives the buffer rod 1601 to move upward along the inner wall of the sleeve 10. The buffer rod 1601 then drives the piston 1602 to move upward synchronously. At this time, the piston 1602 will stretch the spring A1604 sleeved on the outer wall of the buffer rod 1601. During the stretching process, the spring A1604 can absorb and buffer part of the impact force exerted on the rotary tillage blade 11, thereby effectively preventing the rotary tillage blade 11 from being damaged due to instantaneous excessive resistance, ensuring that the soil remediation operation can be carried out stably and efficiently, extending the service life of the equipment, and improving the reliability and connectivity of the remediation liquid injection work.

[0023] A flow regulating mechanism 17 is provided at the top of the base 1. The flow regulating mechanism 17 includes a regulating valve 1701 mounted on the spray assembly. A sleeve 1708 is mounted on the top of the base 1. A push rod 1709 slides inside the sleeve 1708. A push plate 1711 is mounted on one end of the push rod 1709. An air supply pipe 1713 is connected between the rotating rod 7 and the sleeve 1708. It should be noted that, when the suction pump 15 is started, the repair liquid in the liquid storage tank 2 flows along the liquid infusion pipe 13 under the action of the suction force generated by the suction pump 15, and then enters the shunt pipe 12. Under the action of the shunt pipe 12, the repair liquid is evenly dispersed and sprayed to the turned-up soil through the nozzle 14 to achieve the repair treatment of the contaminated soil. When the rotary tillage blade 11 is in operation, the greater the resistance encountered, the higher the compaction degree of the soil, and accordingly more repair liquid is needed to ensure the repair effect. When the rotary tillage blade 11 is caused by excessive soil resistance, the repair liquid is evenly dispersed and sprayed to the turned-up soil through the nozzle 14 to achieve the repair treatment of the contaminated soil. When the buffer rod 1601 drives the piston 1602 to move upward, the piston 1602 squeezes the air inside the rotating rod 7. Under the action of pressure, the gas in the rotating rod 7 flows into the inside of the sleeve 1708 through the gas pipe 1713. As the gas continues to enter the sleeve 1708, the gas pressure in the sleeve 1708 gradually increases. The increased gas pressure pushes the push rod 1709 to slide in the sleeve 1708, so that the push rod 1709 drives the push plate 1711 to move synchronously, and the push plate 1711 drives the rack A 1712 to move synchronously. The meshing relationship between rack A1712 and gear A1707 causes rack A1712 to drive gear A1707 to rotate, thereby gear A1707 drives valve stem 1705 to rotate. Valve stem 1705 and internal threaded barrel 1704 are threadedly connected. The rotation of valve stem 1705 drives internal threaded barrel 1704 to move axially. The movement of internal threaded barrel 1704 drives plugging plate 1703 to slide in throttling barrel 1702. The movement of plugging plate 1703 can change the opening of through hole 1706. When the soil compaction is high, more repair fluid is needed. When the plug 1703 moves, the opening of the through hole 1706 increases, and the flow of the repair fluid in the infusion tube 13 increases when passing through the regulating valve 1701, and finally the amount of repair fluid sprayed from the nozzle 14 increases; on the contrary, when the soil compaction is low and less repair fluid is needed, the plug 1703 moves to reduce the opening of the through hole 1706, and the amount of repair fluid sprayed decreases accordingly, so that the amount of repair fluid sprayed can be accurately and efficiently adjusted according to the actual condition of the soil, which not only ensures the soil repair effect, but also avoids the waste of repair fluid, and improves the quality and efficiency of soil repair work.

[0024] An angle adjustment mechanism 18 is provided on one side of the rotating rod 7. The angle adjustment mechanism 18 includes a rotating shaft 1801 installed inside the rotating rod 7. The rotating shaft 1801 is elastically hinged to the rotating rod 7 through a torsion spring. The outer wall of the rotating shaft 1801 is provided with a gear ring 1802, and the outer wall of the sleeve 10 is provided with a gear ring 1803. One end of the rotating shaft 1801 is installed with a gear B1804 through a one-way bearing, and a connecting rod 1805 is installed on one side of the push plate 1711. A rack B1806 is installed on one end of the connecting rod 1805.

[0025] It should be noted that when the motor 8 drives the rotating rod 7 to rotate clockwise, the rotating rod 7 will drive the rotating shaft 1801 to rotate synchronously through the torsion spring. At this time, the one-way bearing is in an idling state, and the gear B1804 remains stationary. When the push rod 1709 drives the push plate 1711 to move, the push rod 1709 will synchronously drive the connecting rod 1805 to move, prompting the connecting rod 1805 to drive the rack B1806 to move toward the direction close to the base 1. At this time, the one-way bearing is locked. Since the rack B1806 is in meshing relationship with the gear B1804, the rack B1806 will drive the gear B1804 It rotates counterclockwise, and the gear B1804 drives the shaft 1801 to rotate. When the shaft 1801 rotates, it drives the ring gear 1802 to rotate synchronously. Since the ring gear 1802 and the gear ring 1803 are meshed with each other, the rotation of the ring gear 1802 transmits power to the ring gear 1803 through the meshing action, driving the ring gear 1803 to rotate. Finally, the rotation of the gear ring 1803 drives the sleeve 10 to rotate, causing the rotary tillage blade 11 to rotate a certain angle. When the rotary tillage blade 11 rotates to a more inclined angle with the cutting edge, its soil cutting force is enhanced, which can more effectively break the compacted soil into fine particles. Especially in areas with heavy clay soil or hard lumps, the inclined blade can use shear force to tear the soil structure, making the soil particles more uniform, so that the repair liquid can penetrate more fully between the soil particles and achieve a more uniform and tighter combination with the contaminated soil, thereby improving the utilization efficiency of the repair liquid and enhancing the repair effect on the contaminated soil. In loose soil, adjusting the rotary tillage blade 11 to a relatively gentle angle can reduce soil dusting caused by excessive crushing, maintain a certain soil aggregate structure, and facilitate the ecological recovery of the soil after repair.

[0026] In addition, when the rotary tiller blade 11 contacts an obstacle, the rotational action can change the angle and contact method of the rotary tiller blade 11 and the obstacle, thereby preventing the rotary tiller blade 11 from being directly damaged by excessive impact force. At the same time, this rotation can also enable the rotary tiller blade 11 to disperse the force by adjusting its own posture when encountering resistance, thereby reducing local stress concentration and extending the service life of the rotary tiller blade 11.

[0036] Working principle: When using the device to repair heavy metal contaminated soil, the operator first moves the device to the designated soil remediation area, and then starts the motor 8 and the suction pump 15. After the motor 8 is turned on, the output shaft of the motor 8 drives the rotating rod 7 to rotate in a circle, and then the rotating rod 7 drives multiple groups of rotary tillage blades 11 to make circular motion around the axis of the rotating rod 7. When the rotary tillage blades 11 contact the soil, as the rotating rod 7 continues to rotate, the rotary tillage blades 11 gradually penetrate into the soil to realize the turning operation of the soil. Due to the difference in the compactness of the soil in different areas, the rotary tillage blades The resistance experienced by the rotary tiller blade 11 during operation is also the same. When the resistance encountered by the rotary tiller blade 11 reaches a certain threshold, the rotary tiller blade 11 will rotate through the rotating plate 1603 under the reaction force of the soil. The rotating plate 1603 drives the buffer rod 1601 to move upward along the inner wall of the sleeve 10. The buffer rod 1601 then drives the piston 1602 to move upward synchronously. At this time, the piston 1602 will stretch the spring A1604 sleeved on the outer wall of the buffer rod 1601. During the stretching process, the spring A1604 can absorb and buffer part of the impact force experienced by the rotary tiller blade 11. When the suction pump 15 is started, the repair liquid in the liquid storage tank 2 flows along the liquid delivery pipe 13 under the suction force generated by the suction pump 15, and then enters the shunt pipe 12. Under the action of the shunt pipe 12, the repair liquid is evenly dispersed and sprayed to the turned-up soil through the nozzle 14 to achieve the repair treatment of the contaminated soil. When the rotary tillage blade 11 is working, the greater the resistance encountered, the higher the compaction degree of the soil, and accordingly more repair liquid is needed to ensure the repair effect. When the rotary tillage blade 11 causes the buffer rod 1601 to drive the piston 1602 to move upward due to excessive soil resistance, the piston 1602 will squeeze the air inside the rotating rod 7. Under the action of pressure, the gas in the rotating rod 7 flows to the inside of the casing 1708 through the gas delivery pipe 1713. As the gas continues to enter the casing 1708, the gas in the casing 1708 The pressure gradually increases, and the increased gas pressure pushes the push rod 1709 to slide in the sleeve 1708, so that the push rod 1709 drives the push plate 1711 to move synchronously, so that the push plate 1711 drives the rack A1712 to move synchronously, and the rack A1712 drives the gear A1707 to rotate, so that the gear A1707 drives the valve stem 1705 to rotate, and the rotation of the valve stem 1705 drives the internal threaded barrel 1704 to move axially, and the movement of the internal threaded barrel 1704 drives the blocking plate 1703 to slide in the throttling barrel 1702, and the movement of the blocking plate 1703 can change the opening of the through hole 1706. When the soil is highly compacted and more repair fluid is needed, the blocking plate 1703 moves to increase the opening of the through hole 1706, and the flow of the repair fluid in the infusion pipe 13 increases when passing through the regulating valve 1701, and finally the amount of repair fluid sprayed from the nozzle 14 increases; When the motor 8 drives the rotating rod 7 to rotate clockwise, the rotating rod 7 will drive the rotating shaft 1801 to rotate synchronously through the torsion spring. At this time, the one-way bearing is in an idling state, and the gear B1804 remains stationary. When the push rod 1709 drives the push plate 1711 to move, the push rod 1709 will synchronously drive the connecting rod 1805 to move, prompting the connecting rod 1805 to drive the rack B1806 to move toward the direction close to the base 1. At this time, the one-way bearing is locked, and the rack B1806 will drive the gear B1804 to rotate counterclockwise, and the gear B1804 drives the rotating shaft 1801 to rotate. When the rotating shaft 1801 rotates, it will drive the ring gear 1802 to rotate synchronously. The rotation of the ring gear 1802 drives the gear ring 1803 to rotate, and finally the rotation of the gear ring 1803 drives the sleeve 10 to rotate, so that the rotary tiller blade 11 rotates a certain angle.
