Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, specifically to a soil remediation agent spraying device and its usage method. Background Technology

[0002] Soil remediation refers to the use of physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in soil, reducing their concentration to acceptable levels, or converting toxic and harmful pollutants into harmless substances. It also involves changing the form of pollutants in the soil or their binding with the soil, reducing their mobility and bioavailability in the environment, and lowering the concentration of harmful substances in the soil. In soil remediation, remediation agents are used to neutralize pollutants and achieve the effect of soil restoration.

[0003] For example, in publication number CN 113909290 A, this invention discloses a soil remediation agent spraying device, including a movable plate. A cylinder is fixedly installed below the movable plate, and a piston rod is movably installed in the middle of the cylinder. A moving rod is movably connected to the outside of the piston rod. The movable rod is rotated by a ratchet gear, causing the movable frame to rotate. The grinding disc moves up and down, and the grinding disc grinds the soil remediation agent between itself and the grinding box. The ground powdered remediation agent in the grinding box falls into the inclined groove. The rotating wheel rotates, and the actuating rod drives the pushing rod to move back and forth, pushing the powdered remediation agent on the inclined groove to the bottom. The rotating rod rotates, causing the movable plate to move left and right, causing the moving rod to move up and down, which in turn causes the piston rod to move up and down in the cylinder. The aqueous solution in the cylinder is pushed out from the cylinder and dissolves with the remediation agent below the inclined groove. The dissolved remediation agent is sprayed onto the ground by moving the rake with the soil.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, it is discovered that when remediation agents are sprayed, the sprayed state is atomized, which makes them easy to evaporate, resulting in low utilization. Furthermore, after spraying, the remediation liquid remains on the surface and is not easy to penetrate, leading to poor remediation results. Therefore, a soil remediation agent spraying device and its usage method are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a soil remediation agent spraying device and its usage method, which solves the following technical problems: when the remediation agent is sprayed, it is atomized and easily volatilizes, resulting in low utilization rate; secondly, after spraying, the remediation liquid remains on the ground surface and is not easy to penetrate, resulting in poor remediation effect.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A soil remediation agent spraying device includes a vehicle body, a towing seat fixed to one end of the top of the vehicle body, a push hydraulic cylinder mounted on the top side of the vehicle body, and a movable plate fixed to the bottom end of the actuating rod of the push hydraulic cylinder.

[0008] The bottom side of the movable plate is equipped with a spraying structure, which includes a baffle and a fixed plate. The baffle and the fixed plate are arranged in a figure-eight shape. A fan is installed on the fixed plate. A nozzle is fixed on the bottom side of the movable plate and is located between the baffle and the fixed plate. Protective plates are provided on both sides of the baffle and the fixed plate. A curved guide arc panel is provided between the two protective plates. The guide arc panel and the baffle are arranged in a structure that is larger at the top and smaller at the bottom.

[0009] As a further aspect of the present invention: multiple flow dividers are arranged side by side on the inner side of the baffle, and the flow dividers are arranged perpendicular to the inner side of the baffle, which can increase the flow obstruction surface and improve the adsorption surface of the atomized repair agent.

[0010] As a further aspect of the present invention: a liquid storage tank is fixed on the top side of the movable plate, a pump is mounted on the side of the liquid storage tank, the water inlet of the pump is connected to the liquid storage tank through a water inlet pipe, and the output end of the pump is connected to the nozzle through a delivery pipe.

[0011] As a further aspect of the present invention: a perforation structure is provided on the bottom side of the movable plate, the perforation structure including a rolling frame, the rolling frame being fixed on the bottom side of the movable plate, the two ends of the rolling frame being fitted with mating rollers through roller shafts, the middle part of the rolling frame being fitted with a perforating roller through a rotating shaft, a perforating drill bit being fixed on the circumferential surface of the perforating roller, a conveyor belt being mounted on the rolling frame, and the conveyor belt being fitted around the mating roller and the perforating roller, the conveyor belt having insertion holes, and a drive motor being mounted on the rolling frame, the output shaft of the drive motor being connected to the rotating shaft of the perforating roller.

[0012] As a further aspect of the present invention: the conveyor belt is provided with equally spaced insertion holes, and the distance between two rows of insertion holes is the same as the distance between two rows of drilling bits, which can improve the penetration effect of the repair fluid by drilling holes in the ground.

[0013] As a further aspect of the present invention: a positioning hole is provided in the top horizontal plate of the vehicle body, and a positioning rod is movably disposed in the positioning hole. The bottom end of the positioning rod is fixed to the top side of the movable plate, which enables the movable plate to operate stably.

[0014] As a further embodiment of the present invention: a connecting rod is fixed on the mating roller, a mounting bracket is fixed on the connecting rod, a movable hole is opened on the crossbeam of the mounting bracket, a spring is movably arranged in the movable hole, a limit cap is fixed to the top of the spring, a movable rod is fitted on the top of the limit cap, and the movable rod is fixed to the bottom side of the limit cap and the top side of the mounting bracket.

[0015] As a further aspect of the present invention: a scraper is fixedly connected to the bottom end of the spring, and the scraper is located on the outer surface of the conveyor belt, so that the blade of the scraper is tangent to the outer surface of the conveyor belt, thereby removing soil from the surface of the conveyor belt.

[0016] A method for using a soil remediation agent spraying device includes the following steps:

[0017] S1: Prepare the repair agent and mix the towing implement; fill the prepared repair agent into the storage tank, and the entire unit can be towed onto the agricultural machinery through the towing seat;

[0018] S2: Adjust the spray spacing and set the drilling depth; push the movable plate by operating the hydraulic cylinder to push the drilling structure down; determine the drilling depth by the depth of the drilling drill bit on the outside of the drilling roller into the ground.

[0019] S3: Drilling operation; With the help of agricultural machinery towing, the drive motor operates and drives the drilling roller to rotate. With the cooperation of two cooperating rollers, the conveyor belt can be rotated. When the conveyor belt rotates, the drilling bit passes through the hole in sequence to realize the drilling operation on the ground surface. After drilling, when the drilling bit rotates and rotates, the soil carried by the drilling bit after drilling is pushed off by the conveyor belt.

[0020] S4: Soil cleaning; During drilling, there may be soil on the surface of the conveyor belt. An installation frame is set on one side of the rolling frame. The initial state of the movable rod is stretched. Under the contraction of the rolling frame, it can pull the limit cap close to the installation frame, thereby pushing the scraper to make the scraper fit with the surface of the conveyor belt, ensuring that the soil on the surface of the conveyor belt is cleaned and ensuring the continuity of drilling.

[0021] S5: Spraying Repair Agent; After drilling, it forms holes on the ground surface, which improves the penetration of the repair agent, reduces the volatilization of the repair agent on the ground surface, improves the utilization rate of the repair agent, and enhances the repair effect. Through the operation of the pump, the repair agent is delivered to the nozzle and sprayed out. During spraying, the fan operates to blow the atomized residual repair agent into the flared mouth of the baffle and guide arc panel. With the cooperation of the diverter plate, the residual and atomized repair agent is re-condensed and dripped onto the ground surface along the slope of the diverter plate, reducing the atomization and volatilization of the repair agent and improving the utilization rate of the repair agent.

[0022] The beneficial effects of this invention are:

[0023] During spraying, the fan blows the atomized residual repair agent into the flared mouth of the baffle and guide arc panel. With the help of the diversion plate, the residual and atomized repair agent can be re-condensed and dripped onto the ground along the slope of the diversion plate, reducing the atomization and evaporation of the repair agent and improving the utilization rate of the repair agent.

[0024] The drilling process involves sequentially inserting drill bits through holes to create boreholes on the ground surface. After drilling, as the drill bits rotate, the soil carried by the drill bits is pushed off by a conveyor belt. This method allows the remediation fluid on the soil surface to penetrate deeper into the ground, improving its penetration, utilization rate, and overall remediation effect.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] See Figure 1-4 As shown in Figures 6 and 7, the present invention is a soil remediation agent spraying device and its usage method, comprising a vehicle body 1, a towing seat 7 fixed at one end of the top of the vehicle body 1, a pushing hydraulic cylinder 5 mounted on the top side of the vehicle body 1, and a movable plate 10 fixed at the bottom end of the action rod of the pushing hydraulic cylinder 5.

[0037] A spraying structure 11 is mounted on the bottom side of the movable plate 10. The spraying structure 11 includes a baffle 1101 and a fixed plate 1104, which are arranged in a figure-eight shape. A fan 1103 is mounted on the fixed plate 1104. A nozzle 1106 is fixed on the bottom side of the movable plate 10 and is positioned between the baffle 1101 and the fixed plate 1104. Protective plates are provided on both sides of the baffle 1101 and the fixed plate 1104, and a curved surface is provided between the two protective plates. The guide arc panel 1105 is arranged with a larger upper section and a smaller lower section relative to the baffle 1101. Multiple diverter plates 1102 are arranged side-by-side on the inner side of the baffle 1101, perpendicular to the inner side of the baffle 1101. A liquid storage tank 2 is fixed to the top side of the movable plate 10. A pump 3 is mounted on the side of the liquid storage tank 2. The inlet of the pump 3 is connected to the liquid storage tank 2 via an inlet pipe, and the output of the pump 3 is connected to the nozzle 1106 via a delivery pipe 4.

[0038] During operation, soil remediation refers to the use of physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in the soil, reducing their concentration to acceptable levels, or converting toxic and harmful pollutants into harmless substances. In soil remediation, the use of remediation agents can more quickly dissolve pollutants in the soil. When the remediation agent is sprayed, the pump 3 delivers the remediation agent to the nozzle 1106, which sprays it out. During spraying, the fan 1103 blows the atomized residual remediation agent into the bell mouth of the baffle 1101 and the guide arc panel 1105. With the cooperation of the diversion plate 1102, the residual and atomized remediation agent is re-condensed and dripped onto the ground surface along the slope of the diversion plate 1102, reducing the atomization and volatilization of the remediation agent and improving its utilization rate.

[0039] In the above structure, during spraying, the blower 1103 blows the atomized residual repair agent into the flared mouth of the baffle 1101 and the guide arc panel 1105. With the cooperation of the diverter 1102, the residual and atomized repair agent can be re-condensed and dripped onto the ground along the inclined surface of the diverter 1102, reducing the atomization and evaporation of the repair agent and improving the utilization rate of the repair agent.

[0040] Example 2

[0041] Please see Figure 3 , 5 As shown, a perforation structure 9 is provided on the bottom side of the movable plate 10. The perforation structure 9 includes a rolling frame 91, which is fixed to the bottom side of the movable plate 10. Matching rollers 92 are mounted at both ends of the rolling frame 91 via roller shafts. A perforating roller 93 is mounted in the middle of the rolling frame 91 via a rotating shaft. A perforating drill bit 96 is fixed on the circumferential surface of the perforating roller 93. A conveyor belt 94 is mounted on the rolling frame 91, and the conveyor belt 94 is fitted onto the matching rollers 92 and... On the outside of the punching roller 93, the conveyor belt 94 has insertion holes 95. The rolling frame 91 is equipped with a drive motor, and the output shaft of the drive motor is connected to the rotating shaft of the punching roller 93. The conveyor belt 94 has insertion holes 95 at equal intervals, and the distance between two rows of insertion holes 95 is the same as the distance between two rows of punching drill bits 96. The top horizontal plate of the vehicle body 1 has a positioning hole, and a positioning rod 6 is movably installed in the positioning hole. The bottom end of the positioning rod 6 is fixed to the top side of the movable plate 10.

[0042] A connecting rod 97 is fixed on the mating roller 92, and a mounting bracket 98 is fixed on the connecting rod 97. A movable hole is opened on the crossbeam of the mounting bracket 98, and a spring 99 is movably installed in the movable hole. A limit cap 910 is fixed to the top of the spring 99, and a movable rod 911 is fitted on the top of the limit cap 910. The movable rod 911 is fixed to the bottom side of the limit cap 910 and the top side of the mounting bracket 98. A scraper 912 is fixed to the bottom end of the spring 99. The scraper 912 is located on the outer surface of the conveyor belt 94, so that the blade of the scraper 912 is tangent to the outer surface of the conveyor belt 94.

[0043] During operation, conventional spraying of remediation agents leaves residues on the soil surface, resulting in poor penetration and ineffective remediation of deeper soil layers. To improve soil remediation, a drive motor rotates the perforating roller 93, which, in conjunction with two cooperating rollers 92, enables the conveyor belt 94 to rotate. As the conveyor belt 94 rotates, the perforating drill bit 96 sequentially penetrates the insertion hole 95, achieving surface drilling. After drilling, as the perforating drill bit 96 rotates, the soil carried by it is pushed off by the conveyor belt 94. This drilling operation allows the remediation liquid on the soil surface to penetrate deeper into the soil, improving the utilization rate of the remediation and enhancing the overall remediation effect.

[0044] During drilling, soil may be present on the surface of the conveyor belt 94. An mounting bracket 98 is provided on one side of the rolling frame 91. The movable rod 911 is initially in a stretched state. Under the contraction of the rolling frame 91, it can pull the limit cap 910 close to the mounting bracket 98, thereby pushing the scraper 912 to make the scraper 912 fit against the surface of the conveyor belt 94, ensuring that the soil on the surface of the conveyor belt 94 is cleaned and ensuring the continuity of drilling.

[0045] The above-mentioned structure is configured to drill through the holes 95 sequentially by the drilling bit 96 to achieve drilling operations on the ground surface. After drilling, when the drilling bit 96 rotates, the soil carried by the drilling bit 96 is pushed off by the conveyor belt 94. This enables drilling operations on the soil, allowing the remediation liquid on the soil surface to penetrate deeper into the ground, thus improving the utilization rate of the remediation and enhancing the remediation effect on the soil.

[0046] A method for using a soil remediation agent spraying device includes the following steps:

[0047] S1: Prepare the repair agent and mix the towing implement; fill the prepared repair agent into the storage tank 2, and the entire unit can be towed onto the agricultural machinery through the towing seat 7;

[0048] S2: Adjust the spray spacing and set the drilling depth; push the movable plate 10 by pushing the hydraulic cylinder 5 to push the drilling structure 9 down; determine the drilling depth by the depth of the drilling drill bit 96 on the outside of the drilling roller 93 into the ground.

[0049] S3: Drilling operation; With the help of agricultural machinery towing, the drive motor operates, driving the drilling roller 93 to rotate. With the cooperation of two cooperating rollers 92, the conveyor belt 94 can be rotated. When the conveyor belt 94 rotates, the drilling bit 96 passes through the insertion hole 95 in sequence to realize the drilling operation on the ground surface. After drilling, when the drilling bit 96 rotates and rotates, the soil carried by the drilling bit 96 after drilling is pushed off by the conveyor belt 94.

[0050] S4: Soil cleaning; During drilling, soil may be present on the surface of the conveyor belt 94. An mounting frame 98 is provided on one side of the rolling frame 91. The initial state of the movable rod 911 is stretched. Under the contraction of the rolling frame 91, the limit cap 910 can be pulled close to the mounting frame 98, thereby pushing the scraper 912 to make the scraper 912 fit against the surface of the conveyor belt 94, ensuring that the soil on the surface of the conveyor belt 94 is cleaned and ensuring the continuity of drilling.

[0051] S5: Spraying the repair agent; After drilling, holes are formed on the ground surface, which can improve the penetration of the repair agent, reduce the volatilization of the repair agent on the ground surface, improve the utilization rate of the repair agent, and improve the repair effect of the repair agent. The repair agent is delivered to the nozzle 1106 through the operation of the pump 3 and sprayed out through the nozzle 1106. During the spraying, the fan 1103 operates to blow the atomized residual repair agent into the flared mouth of the baffle 1101 and the guide arc panel 1105. With the cooperation of the diverter plate 1102, the residual and atomized repair agent can be re-condensed and dripped onto the ground surface along the slope of the diverter plate 1102, reducing the atomization and volatilization of the repair agent and improving the utilization rate of the repair agent.
