Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, and in particular to an active soil ecological restoration device for mountains. Background Technology

[0002] Contaminated soil is difficult to restore and poses a threat to agricultural products and human health. Therefore, soil ecology needs to be restored. Ex-situ remediation has advantages such as high efficiency, mature technology, low risk, easy control, strong replicability, thorough remediation, and low cost. Therefore, the current remediation of industrial contaminated soil adopts physical or chemical methods for ex-situ remediation.

[0003] A soil ecological restoration device, disclosed in CN118616471A, relates to the field of soil ecological restoration technology. It includes a base plate with four supporting legs, a restoration box on the base plate, a first through-hole inlet on the restoration box, two discharge pipes connected to the bottom wall of the restoration box at their first ends, and both discharge pipes penetrating the base plate at their second ends. Electromagnetic valves are installed inside the discharge pipes. A soil-mixing and pulverizing mechanism is installed inside the restoration box. Spraying mechanisms for restoring soil are installed on both sides of the restoration box outside the pulverizing mechanism, driven by the pulverizing mechanism. A support rod is provided on one side of the base plate of the restoration box, and a purification box is mounted on the support rod. The purification box has a third through-hole inlet and a discharge outlet. A second through-hole connecting pipe connects the restoration box and the purification box. This invention has a simple and reliable structure, good soil ecological restoration effect, and convenient control.

[0004] The soil ecological restoration device proposed in the above patent documents involves stirring the soil inside the restoration tank during actual use. However, because the soil becomes viscous after the restoration liquid is sprayed, some soil accumulates in various corners of the tank, making it impossible to fully stir the soil in those areas. This results in insufficient and uneven mixing of the soil and restoration liquid, hindering their integration and leading to unsatisfactory soil restoration results. Therefore, this invention provides an active soil ecological restoration device for mountains. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The present invention provides an active soil ecological restoration device for mountains, comprising: a base plate, wherein a restoration mechanism and a pretreatment mechanism are provided on the upper surface of the base plate; The pretreatment mechanism includes a fixed frame, a pretreatment box fixedly mounted at the top of the fixed frame, two crushing rollers rotatably mounted inside the pretreatment box, an arc-shaped screen plate mounted on the inner wall of the pretreatment box, a discharge square tube fixedly mounted at the bottom of the pretreatment box, a linkage frame mounted inside the discharge square tube, several unblocking rods fixedly mounted on the surface of the linkage frame, a transmission rod rotatably mounted on the inner wall of the pretreatment box, a linkage cam fixedly mounted on the surface of the transmission rod, the top of the linkage frame extending into the interior of the pretreatment box and fixedly mounted on a movable push plate, and the linkage cam located between the movable push plate and the arc-shaped screen plate. The repair mechanism includes a roller, with a feed pipe rotatably connected to the right end of the roller. The bottom end of the discharge square tube extends into the inside of the feed pipe. A spiral conveying rod is rotatably installed inside the feed pipe. A liquid guide tube is inserted and installed inside the spiral conveying rod. The left end of the liquid guide tube extends into the inside of the roller and is fixedly connected to a diversion pipe. Rotating square tubes are fixedly installed at both the upper and lower ends of the diversion pipe.

[0007] By adopting the above technical solution, the soil can be crushed and pulverized using two crushing rollers in the pretreatment box, thereby crushing some pollutants in the soil. At the same time, the crushing rollers can drive the linkage cam on the surface of the transmission rod to rotate, and then use the linkage cam to push the arc-shaped screen plate upward. The arc-shaped screen plate can be used to screen and filter the soil, making the soil finer. At the same time, the arc-shaped screen plate vibrates up and down under the action of the linkage cam, thereby vibrating and dropping the soil on the surface of the arc-shaped screen plate, preventing soil from clogging inside the screen holes on the surface of the arc-shaped screen plate.

[0008] Preferably, a plurality of nozzles are embedded in the surface of the rotating square tube, and a plurality of stirring plates are fixedly connected between two rotating square tubes. Scrapers are fixedly provided on the sides of the two rotating square tubes that are far apart from each other. A cylindrical filter screen is fixedly provided on the inner wall of the roller, and the position of the scraper corresponds to the inner wall of the cylindrical filter screen.

[0009] By adopting the above technical solution, the soil can be tumbled and moved inside the cylindrical filter screen by the roller, while the soil remediation liquid is delivered to the rotating square tube inside the roller through the liquid guide pipe, and the liquid is evenly sprayed inside the roller by several nozzles on the surface of the rotating square tube, so that the remediation liquid can fully contact and mix with the soil, thereby improving the soil remediation effect.

[0010] Preferably, the inner wall of the drum is fixedly provided with a plurality of electric heating tubes, which are evenly distributed in a ring array between the drum and the cylindrical filter screen.

[0011] By adopting the above technical solution, several electric heating tubes can be used to heat the inside of the drum, which helps to improve the reaction speed between the soil and the remediation solution.

[0012] Preferably, the right end of the spiral conveyor rod extends outside the feed pipe and is fixedly connected to a driven gear. A first drive motor is fixedly mounted on the right end of the feed pipe, and a drive gear is fixedly mounted on the output shaft of the first drive motor. The drive gear meshes with the driven gear.

[0013] By adopting the above technical solution, the first drive motor can be used to drive the drive gear and the driven gear to rotate, thereby driving the screw conveyor rod to rotate inside the feed pipe.

[0014] Preferably, rubber connecting strips are fixedly connected between the two sides of the arc-shaped screen plate and the inner wall of the pretreatment box. The arc-shaped screen plate is located directly below the two crushing rollers. The linkage cam overlaps with the bottom of the arc-shaped screen plate and overlaps with the upper surface of the movable push plate. A fixing strip is fixedly provided on the inner wall of the pretreatment box. The linkage frame is slidably connected to the surface of the fixing strip. A return spring is sleeved on the surface of the linkage frame. The top end of the return spring is fixedly connected to the lower surface of the movable push plate, and the bottom end of the return spring is fixedly connected to the upper surface of the fixing strip.

[0015] By adopting the above technical solution, while the transmission rod rotates, the linkage cam pushes the movable push plate at the top of the linkage frame downwards. Under the action of the return spring, the movable push plate drives the linkage frame to move up and down, thereby driving several unblocking rods on the surface of the linkage frame to move back and forth inside the discharge square tube. The unblocking rods can be used to vibrate and unblock the soil in the discharge square tube, preventing the discharge square tube from being blocked by soil and increasing the speed of soil discharge from the pretreatment box.

[0016] Preferably, a second drive motor is fixedly installed on the right side of the pretreatment box, and a drive pulley is fixedly provided on the output shaft of the second drive motor. One end of the rotating shaft of each of the two crushing rollers extends to the outside of the pretreatment box and is fixedly connected to a transmission gear. The two transmission gears mesh with each other, and a driven pulley is fixedly provided on the surface of one of the transmission gears. A transmission belt is sleeved between the drive pulley and the driven pulley.

[0017] By adopting the above technical solution, the second drive motor can drive the drive pulley to rotate, and through the transmission belt, it can drive the driven pulley to rotate, thereby driving the shaft of one of the crushing rollers to rotate. Then, by using the meshing of two transmission gears, the two crushing rollers can rotate in opposite directions, which facilitates the compression and crushing of the soil.

[0018] Preferably, the output shaft of the second drive motor extends into the interior of the pretreatment box and is fixedly connected to one end of the transmission rod. The second drive motor is used to simultaneously drive the two crushing rollers and the transmission rod to rotate.

[0019] Preferably, a third drive motor is fixedly mounted on the upper surface of the base plate, a rotating gear is fixedly mounted on the output end of the third drive motor, and a toothed ring is fixedly mounted on the surface of the roller. The position of the toothed ring corresponds to that of the rotating gear, and the rotating gear meshes with the toothed ring.

[0020] By adopting the above technical solution, the third drive motor can drive the rotating gear to rotate, which in turn drives the gear ring to rotate, and the gear ring drives the drum to rotate.

[0021] Preferably, four support seats are fixedly provided on the upper surface of the base plate, and the top of the support seats is rotatably connected to a limiting support wheel. The four limiting support wheels are symmetrically distributed on both sides of the bottom of the roller, and the limiting support wheels are slidably connected to the surface of the roller.

[0022] By adopting the above technical solution, the bottom of the drum can be supported and limited by the limiting support wheel, so that the drum remains stable during rotation.

[0023] Preferably, the left end of the roller is provided with a discharge port, and a cover is installed on the left end of the roller, the size of which matches the discharge port.

[0024] By adopting the above technical solution, the soil inside the drum can be discharged through the discharge port, and the discharge port can be blocked and sealed with a cover.

[0025] The beneficial effects of this invention are as follows: The active soil ecological restoration device for mountains described in this invention, by setting up a pretreatment mechanism, can use two crushing rollers in the pretreatment box to crush and grind the soil, thereby crushing some pollutants in the soil. At the same time as the crushing rollers rotate, they can drive the linkage cam on the surface of the transmission rod to rotate, and then use the linkage cam to push the arc-shaped screen plate upward. The arc-shaped screen plate can be used to screen and filter the soil, making the soil finer. At the same time, the arc-shaped screen plate generates an up-and-down vibration effect under the action of the linkage cam, thereby vibrating and dropping the soil on the surface of the arc-shaped screen plate, avoiding soil blockage inside the screen holes on the surface of the arc-shaped screen plate.

[0026] The active soil ecological restoration device for mountains described in this invention has a linkage frame installed inside the discharge square tube. When the transmission rod rotates, the linkage cam pushes the movable push plate at the top of the linkage frame downward. Under the action of the return spring, the movable push plate drives the linkage frame to move up and down, which in turn drives several unblocking rods on the surface of the linkage frame to move back and forth inside the discharge square tube. The unblocking rods can be used to vibrate and unblock the soil in the discharge square tube, preventing the discharge square tube from being blocked by soil and increasing the speed of soil discharge from the pretreatment box.

[0027] The active soil ecological restoration device for mountains described in this invention uses a roller with a cylindrical filter screen inside. The roller can move the soil around inside the filter screen, while a liquid guide pipe delivers soil restoration liquid to a rotating square tube inside the roller. Several nozzles on the surface of the rotating square tube spray the liquid evenly inside the roller, allowing the restoration liquid to fully contact and mix with the soil, thus improving the restoration effect.

[0030] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples. Example

[0031] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Please refer to the accompanying drawings. Figures 1 to 8 The present application provides an active soil ecological restoration device for mountains, comprising: a base plate, wherein a restoration mechanism 1 and a pretreatment mechanism 2 are provided on the upper surface of the base plate.

[0032] See Figures 1 to 5 The pretreatment mechanism 2 includes a fixed frame, and a pretreatment box 201 is fixedly installed at the top of the fixed frame. Two crushing rollers 203 are rotatably installed inside the pretreatment box 201.

[0033] Specifically, the soil can be pre-treated by crushing using two crushing rollers 203, which crushes some solid pollutants in the soil, making it easier to screen and remove the pollutants.

[0034] A second drive motor 214 is fixedly installed on the right side of the pretreatment box 201. A drive pulley 215 is fixedly installed on the output shaft of the second drive motor 214. One end of the rotating shaft of each of the two crushing rollers 203 extends to the outside of the pretreatment box 201 and is fixedly connected to a transmission gear 216. The two transmission gears 216 mesh with each other. A driven pulley 217 is fixedly installed on the surface of one of the transmission gears 216. A transmission belt 202 is sleeved between the drive pulley 215 and the driven pulley 217.

[0035] See Figure 3 The inner wall of the pretreatment box 201 is provided with an arc-shaped screen plate 204. The bottom of the pretreatment box 201 is fixedly provided with a discharge square tube 205. The inside of the discharge square tube 205 is provided with a linkage frame 206. Several unblocking rods 207 are fixedly provided on the surface of the linkage frame 206. The inner wall of the pretreatment box 201 is rotated by a transmission rod 208.

[0036] The output shaft of the second drive motor 214 extends into the interior of the pretreatment box 201 and is fixedly connected to one end of the transmission rod 208. The second drive motor 214 is used to simultaneously drive the two crushing rollers 203 and the transmission rod 208 to rotate.

[0037] See Figure 5The second drive motor 214 can drive the drive pulley 215 to rotate, and drive the driven pulley 217 to rotate through the transmission belt 202, which in turn drives the shaft of one of the crushing rollers 203 to rotate. Then, by using the two transmission gears 216 to mesh with each other, the two crushing rollers 203 can rotate in opposite directions, which facilitates the compression and crushing of the soil.

[0038] See Figure 4 A linkage cam 209 is fixed on the surface of the transmission rod 208. The top of the linkage frame 206 extends into the interior of the pretreatment box 201 and is fixed with a movable push plate 210. The linkage cam 209 is located between the movable push plate 210 and the arc-shaped screen plate 204.

[0039] In this invention, a linkage frame 206 is installed inside the discharge square tube 205. While the transmission rod 208 rotates, the linkage cam 209 pushes the movable push plate 210 at the top of the linkage frame 206 downwards. Under the action of the return spring 212, the movable push plate 210 causes the linkage frame 206 to move up and down, thereby causing several unblocking rods 207 on the surface of the linkage frame 206 to reciprocate inside the discharge square tube 205. The unblocking rods 207 can be used to vibrate and unblock the soil in the discharge square tube 205, preventing the discharge square tube 205 from being blocked by soil and increasing the soil discharge speed from the pretreatment box 201. Rubber connecting strips 211 are fixedly connected between the two sides of the arc-shaped screen plate 204 and the inner wall of the pretreatment box 201. The arc-shaped screen plate 204 is located directly below the two crushing rollers 203. The linkage cam 209 overlaps with the bottom of the arc-shaped screen plate 204 and overlaps with the upper surface of the movable push plate 210. A fixing strip is fixedly installed on the inner wall of the pretreatment box 201. The linkage frame 206 is slidably connected to the surface of the fixing strip. A return spring 212 is sleeved on the surface of the linkage frame 206. The top end of the return spring 212 is fixedly connected to the lower surface of the movable push plate 210 and the bottom end of the return spring 212 is fixedly connected to the upper surface of the fixing strip.

[0040] In this invention, by setting up a pretreatment mechanism 2, the soil can be crushed and pulverized by two crushing rollers 203 in the pretreatment box 201, thereby crushing some pollutants in the soil. At the same time as the crushing rollers 203 rotate, the linkage cam 209 on the surface of the transmission rod 208 can be rotated. Then, the linkage cam 209 pushes the arc-shaped screen plate 204 upward, which can be used to screen and filter the soil, making the soil finer. At the same time, the arc-shaped screen plate 204 vibrates up and down under the action of the linkage cam 209, thereby vibrating and dropping the soil on the surface of the arc-shaped screen plate 204, avoiding the soil from clogging inside the screen holes on the surface of the arc-shaped screen plate 204.

[0052] In this invention, a roller 101 is provided, and a cylindrical filter screen 110 is provided inside the roller 101. The soil can be moved by the roller 101 and rolled inside the cylindrical filter screen 110. At the same time, soil remediation liquid is delivered to the rotating square tube 106 inside the roller 101 by the liquid guide pipe 104, and the soil is evenly sprayed inside the roller 101 by several nozzles 107 on the surface of the rotating square tube 106, so that the remediation liquid can fully contact and mix with the soil, thereby improving the soil remediation effect.

[0054] Specifically, several electric heating tubes 111 can be used to heat the inside of the drum 101, which helps to improve the reaction speed between the soil and the remediation solution.

[0055] Working principle: First, the soil is placed into the pretreatment box 201. The second drive motor 214 drives the drive pulley 215 to rotate, which in turn drives the driven pulley 217 to rotate via the transmission belt 202. This, in turn, drives the shaft of one of the crushing rollers 203 to rotate. Then, the two transmission gears 216 mesh with each other, which makes the two crushing rollers 203 rotate in opposite directions, which facilitates the compression and crushing of the soil. Then, the crushed soil is fed into the feed pipe 102 through the discharge square pipe 205. The soil is fed into the drum 101 through the screw conveyor 103. The third drive motor 3 drives the rotating gear 4 to rotate, which in turn drives the gear ring 5 to rotate. The gear ring 5 drives the drum 101 to rotate.

[0056] The soil is moved by the roller 101 and tumbled inside the cylindrical filter screen 110. At the same time, the liquid guide pipe 104 delivers soil remediation liquid to the rotating square tube 106 inside the roller 101. Several nozzles 107 on the surface of the rotating square tube 106 spray the liquid evenly inside the roller 101, so that the remediation liquid can fully contact and mix with the soil, thereby improving the soil remediation effect. The waste liquid generated after remediation is filtered by the cylindrical filter screen 110 and deposited at the bottom of the roller 101, realizing the filtration, remediation and separation of pollutants in the soil.
