Description

Technical Field

[0001] This invention belongs to the field of soil remediation technology, specifically a soil remediation device and method for soil and water conservation. Background Technology

[0002] Soil remediation devices for soil and water conservation aim to improve and restore the structure, function, and ecological health of damaged soil. Such devices combine various technologies, equipment, and materials, depending on the type, degree, and remediation goals of soil degradation. For surface soil remediation, a variety of methods are typically employed, including soil amendment application, vegetation restoration, and soil conservation. Soil amendments include natural and artificial soil amendments, which are materials that improve the physical, chemical, and biological properties of soil. While they do not provide nutrients to plants themselves, they can promote the absorption and utilization of nutrients by crops. Soil amendments can improve soil aggregate structure, increase capillary and non-capillary porosity, reduce soil bulk density, increase soil aeration, and make the soil looser, which is conducive to root growth and development. They can also increase the soil's water and fertilizer retention capacity, reduce water and nutrient loss, improve the persistence of soil fertility, and provide a stable environment for crop growth, thereby achieving soil remediation for soil and water conservation. This method is widely used.

[0003] In existing soil remediation devices for soil and water conservation, the application of soil conditioners to the soil surface typically involves a crushing and feeding device to crush various composite soil conditioners before application. However, due to the different structural states of the components in the mixed soil conditioner, blockages may occur at the discharge port during application, affecting subsequent applications. This often requires manual clearing, which is time-consuming and labor-intensive, significantly reducing the efficiency of continuous application.

[0004] Furthermore, in the actual application of soil conditioner, when it is necessary to pause the application process, since the application port is continuously open, it is often necessary to manually close the outlet or use electrical control equipment to close the outlet when temporarily stopping or changing the application location. The former results in some soil conditioner continuously falling out during the operation, which is wasteful, while the latter requires the addition of electrical control equipment, which increases costs and the overall effect is not good.

[0009] Preferably, the fixed shaft is fixedly connected to both ends of the rolling cylinder, and both fixed shafts are rotatably sleeved with the discharge cylinder. The rolling cylinder is located in the discharge port, and the bottom of the rolling cylinder is on the same horizontal plane as the bottom of the movable support wheel. The gear is fixedly sleeved on the outer surface of a fixed shaft, and an internal cavity is opened inside the rolling cylinder. The counterweight rod is eccentrically fixed in the internal cavity.

[0010] Preferably, the cam assembly includes a rotating shaft, a bearing, a second gear, and a cam.

[0013] Preferably, the bottom of the fixed cylinder is provided with an adapter groove, the inner surface of the adapter groove is rotatably sleeved with the cam, and the cam is located at the bottom of the push block and is always in contact with the push block.

[0014] A method for repairing soil remediation devices used for soil and water conservation includes the following repair steps:

[0015] Step 1: Before the repair, put the soil conditioner to be repaired into the primary treatment box, so that the device is placed on the soil area to be repaired. Start the crushing roller in the primary treatment box to crush the soil conditioner and let it fall into the discharge cylinder, pushing the device forward. The fallen soil conditioner falls out along the gap between the roller and the discharge port at the bottom of the discharge cylinder, so that the soil conditioner is evenly fed.

[0016] Step 2: As the pushing device moves forward, the air supply pump is activated, and gas is introduced into the distribution assembly. As the rolling assembly rotates, the rotating gear drives the meshing cam assembly to rotate, causing the cam in the cam assembly to rotate continuously. When the cam rotates to the top, it pushes the push block, push rod, and movable plug in the sealing assembly upwards, compressing the spring. At this time, the movable plug moves above the first hole. The air supply pump then introduces gas through the first hole, the second hole, the connecting sleeve, the connecting pipe, and the through hole into the connecting arc cavity, thereby rapidly introducing gas into the elastic airbag. As the elastic airbag inflates... The arc-shaped opening and closing door in the assembly arc groove is pushed outward along the assembly arc groove and collides with the rolling drum. When the cam rotates to the bottom, the movable plug is located below the first hole and seals the second hole. The air supply pump supplies air into the discharge cylinder through the first hole, the third hole and the bypass pipe. The elastic airbag contracts elastically, and the previously introduced gas flows out through the connecting pipe, the connecting sleeve, the second hole, the first groove and the second groove. The contracted elastic airbag drives the opening and closing door to reset and move into the assembly arc groove. As the cam continues to rotate, the opening and closing door intermittently collides with the rolling drum, and the blocked soil conditioner falls out smoothly after vibration.

[0017] Step 3: When the soil conditioner needs to be paused or stopped during the application process, as the device moves to the target stop position, it is slightly lifted up, causing the rolling component in the device to briefly detach from the soil and suspend in the air. At this time, the rolling component is deflected by the center of gravity of the internal counterweight rod, causing the position of the counterweight rod in the rolling cylinder to swing quickly and automatically to the vertical downward. As the rolling cylinder deflects quickly, the cam component is driven to deflect quickly through gear one, causing the cam to swing quickly to the top of the protrusion and maintain the state of pushing the sealing component. This keeps the movable plug above the first hole, maintaining the state of the air supply pump inputting gas into the elastic airbag. At this time, the expanded elastic airbag pushes the opening and closing door to extend outward and presses tightly against the outer surface of the rolling cylinder, automatically locking the discharge port and stopping the material discharge. After a brief lifting and automatic sealing, the device is slowly lowered to maintain the stopped material discharge state.

[0018] Step 4: When it is necessary to clean the inside of the device, push the device to make the rolling component roll, and keep the cam rotating and located at the bottom. At this time, the movable plug is located below the first hole and seals the second hole. The air supply pump supplies air along the first hole, the third hole and the bypass pipe into the inside of the discharge cylinder. The flowing air in the discharge cylinder blows the inside of the discharge cylinder to complete the blowing and cleaning.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention utilizes the rolling motion of a rolling assembly to deliver soil remediation amendments along the top of the soil. During this rotation, a cam assembly drives a sealing assembly to move up and down within a distribution assembly. The intermittent pushing effect of the cam causes gas introduced into the distribution assembly to intermittently enter the connecting arc cavity. As the gas enters the connecting arc cavity, it fills an expanding elastic air bladder, pushing the opening and closing gate to briefly seal the outlet. Simultaneously, the sealing assembly impacts the rolling assembly, releasing the gas from the elastic air bladder after its final action. This intermittent collision between the opening and closing gate and the rolling assembly, along with the device's forward movement, intermittently compresses and disturbs the outlet gap, achieving automatic vibration during the feeding process. This effectively prevents blockage at the outlet, maintaining stable and uniform feeding.

[0021] 2. This invention utilizes the rolling motion of the rolling assembly again, and employs an eccentrically arranged counterweight rod within the rolling assembly. When the device is slightly lifted and the rolling assembly is suspended off the ground, it automatically deflects and resets to a designated state. This ensures that the counterweight rod in the rolling cylinder is vertically downward. In conjunction with the meshing arrangement of gears one and two, during assembly and adjustment, when the rolling cylinder rotates to the point where the counterweight rod is vertically downward, the cam's protrusion is simultaneously positioned upwards. This ensures that when the device is slightly lifted and the rolling assembly is briefly suspended, the cam position is controlled, guaranteeing that the sealing assembly compresses and seals the No. 3 hole, ensuring the input... Gas is continuously introduced into the elastic airbag to achieve a continuous seal between the opening and closing door and the discharge port. After the lifting operation and resetting, as long as the device remains stationary, it can maintain a sealed state without material falling out. When it is necessary to pause during soil feeding, it can achieve rapid automatic sealing without the need for a special electronic sealing device or manual active sealing. The temporary sealing operation after the actual pause is simple and quick, avoiding the continuous falling out of soil conditioner during the intermediate pause operation. When it is necessary to move and change the feeding position, the device can be lifted again and the feeding position can be changed by relying on the two sets of moving support wheels at the front of the device. The effect is good.

[0022] 3. This invention controls the air distribution direction of the distribution component by utilizing the sealing component again. When the rolling component is rotated by the pushing device, the cam component is observed to rotate to the lower position and remain stationary. At this time, the air supply pump inputs gas into the inside of the discharge cylinder. With the discharge port open, the continuous air volume supplied into the discharge cylinder is used for air purging. No additional cleaning equipment is needed, which can quickly achieve internal cleaning, prevent the deterioration of residual soil conditioner, improve the quality of subsequent soil remediation, and achieve good results.

[0033] 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.

[0034] like Figures 1 to 9As shown, this embodiment of the invention provides a soil remediation device and method for soil and water conservation, including a primary treatment box 1, movable support wheels 2, and a discharge cylinder 3. The discharge cylinder 3 has a discharge port 5 at its bottom. An assembly arc groove 6 and a connecting arc cavity 7 are respectively formed in the inner wall of the discharge cylinder 3. The connecting arc cavity 7 and the assembly arc groove 6 are connected. An elastic airbag 10 is fixedly installed in the assembly arc groove 6. The connecting arc cavity 7 is connected to the elastic airbag 10. An opening and closing door 9 is movably sleeved inside the assembly arc groove 6. The elastic airbag 10 and the opening and closing door... 9. Fixed connection: The bottom of the discharge cylinder 3 is rotatably provided with a rolling assembly 4, and the end face of the discharge cylinder 3 is rotatably installed with a cam assembly 11. The cam assembly 11 is meshed with the rolling assembly 4. The end face of the discharge cylinder 3 is fixedly provided with a fixed cylinder 12, and the top of the fixed cylinder 12 is fixedly provided with a distribution assembly 13. The top of the distribution assembly 13 is fixedly installed with an air supply pump 14. The distribution assembly 13 and the fixed cylinder 12 are provided with a sealing assembly 15. The two outlet ends of the distribution assembly 13 are respectively connected to the connecting arc cavity 7 and the inside of the discharge cylinder 3.

[0035] The rolling assembly 4 includes a rolling cylinder 41, a fixed shaft 42, a gear 43, and a counterweight rod 44.

[0036] Example 1: In use, before remediation, the soil conditioner to be remediated is added to the primary treatment tank 1, and the device is placed on the soil area to be remediated. The crushing roller in the primary treatment tank 1 is activated, causing the soil conditioner to be crushed and fall into the discharge cylinder 3, pushing the device forward. The fallen soil conditioner falls out along the gap between the rolling drum 41 and the discharge port 5 at the bottom of the discharge cylinder 3, ensuring uniform feeding of the soil conditioner. As the device moves forward, the air supply pump 14 is activated, and gas is introduced into the distribution component 13. As the rolling component 4 rotates, the rotating gear 43 drives the meshing cam component 11 to rotate, causing the cam 114 in the cam component 11 to rotate continuously. When the cam 114 rotates to the top, it pushes the push block 151, push rod 152 and movable plug 153 in the sealing component 15 to move upward and compress the spring 154. At this time, the movable plug 153 moves above the first hole 132, and the air supply pump 14 then sends gas through the first hole 132. The second hole 133, connecting sleeve 135, connecting pipe 137, and through hole 8 are connected to the connecting arc cavity 7, thereby allowing gas to be quickly introduced into the elastic airbag 10. As the elastic airbag 10 inflates, it pushes the arc-shaped opening and closing door 9 in the assembly arc groove 6 to move outward along the assembly arc groove 6 and collide with the rolling cylinder 41. When the cam 114 rotates to the lower position, the movable plug 153 is located below the first hole 132 and seals the second hole 133. The air supply pump 14 supplies air along the first hole 132. The gas enters the discharge cylinder 3 through hole 132, hole 134 and bypass pipe 136. The elastic airbag 10 contracts elastically, and the previously introduced gas bypasses through the connecting pipe 137, connecting sleeve 135, hole 133, slot 155 and slot 156. The contracted elastic airbag 10 drives the opening and closing door 9 to reset and move into the assembly arc groove 6. As the cam 114 rotates continuously, the opening and closing door 9 intermittently hits the rolling cylinder 41, and the blocked soil conditioner is vibrated and falls out smoothly.

[0037] First, by utilizing the rolling component 4, when the soil remediation amendment is applied along the top of the soil, the rotating component 4, in conjunction with the cam component 11, drives the sealing component 15 to move up and down within the distribution component 13. The intermittent pushing effect of the cam 114 causes the gas introduced into the distribution component 13 to intermittently enter the connecting arc cavity 7. As the gas is guided into the connecting arc cavity 7, it fills the expanding elastic airbag 10, pushes the opening / closing door 9 to move, and briefly seals the outlet 5. Simultaneously, it impacts the rolling component 4. After the sealing component 15's sole action, the gas in the elastic airbag 10 is released. This allows the opening / closing door 9 to intermittently collide with the rolling component 4 as it moves forward with the device, and intermittently squeezes and disturbs the outlet gap of the outlet 5. This achieves automatic vibration during the forward feeding process, effectively preventing blockage at the outlet 5 and maintaining stable and uniform feeding.

[0038] Example 2: When the soil conditioner application process needs to be paused or stopped, as the device moves to the target stopping position, it is slightly lifted, causing the rolling component 4 in the device to briefly detach from the soil and suspend in the air. At this time, the rolling component 4 is deflected by the center of gravity of the internal counterweight rod 44, causing the position of the counterweight rod 44 in the rolling cylinder 41 to swing rapidly and automatically downward. As the rolling cylinder 41 deflects rapidly, the cam component 11 is driven to deflect rapidly through the gear 43, causing the cam 114 to swing rapidly until the protrusion is above and maintains the state of pushing the sealing component 15. This keeps the movable plug 153 above the first hole 132, maintaining the state of the air supply pump 14 inputting gas into the elastic airbag 10. At this time, the inflated elastic airbag 10 pushes the opening and closing door 9 to extend outward and make tight contact with the outer surface of the rolling cylinder 41. The discharge port 5 automatically locks, stopping the material discharge. After the brief lifting and automatic sealing, the device is slowly lowered to maintain the stopped material discharge state.

[0039] First, by utilizing the rolling assembly 4 again, and using the eccentrically arranged counterweight rod 44 in the rolling assembly 4, when the device is slightly lifted and the rolling assembly 4 is suspended off the ground, it automatically deflects and resets to the designated state, achieving a vertically downward position for the counterweight rod 44 in the rolling cylinder 41. In conjunction with the meshing arrangement of gear one 43 and gear two 113, during assembly, when the rolling cylinder 41 rotates to the point where the counterweight rod 44 is vertically downward, the cam 114, which is in a meshing linkage, is simultaneously positioned at the top. This ensures that the position of the cam 114 is controlled when the device is slightly lifted and the rolling assembly 4 is briefly suspended, ensuring that the sealing assembly 15 is compressed and sealed at this time. The No. 3 hole 134 ensures that the gas is continuously supplied into the elastic airbag 10, so as to achieve continuous sealing of the outlet 5 by the opening and closing door 9. After the lifting operation and reset, as long as the device is kept stationary, it can maintain a sealed state without material falling. When it is necessary to pause during the soil feeding process, it can achieve quick automatic sealing without the need to add a special electric control sealing device or perform active sealing under manual operation. The temporary sealing operation after the actual pause is simple and quick, avoiding the continuous falling of soil conditioner during the intermediate pause operation. When it is necessary to move and change the feeding position, the device can be lifted again and the feeding position can be changed by relying on the two sets of moving support wheels 2 at the front of the device. The effect is good.

[0040] Example 3: When the inside of the device needs to be cleaned, push the device to make the rolling assembly 4 roll, and keep the cam 114 rotating and located at the bottom. At this time, the movable plug 153 is located below the first hole 132 and seals the second hole 133. The air supplied by the air pump 14 enters the inside of the discharge cylinder 3 through the first hole 132, the third hole 134 and the bypass pipe 136. The flowing air in the discharge cylinder 3 blows the inside of the discharge cylinder 3, completing the blowing and cleaning.

[0041] First, by controlling the air distribution direction of the distribution component 13 again using the sealing component 15, when the rolling component 4 is rotated by the pushing device, the cam component 11 is observed to rotate the cam 114 to the lower position and remain stationary. At this time, the air supply pump 14 inputs gas into the interior of the discharge cylinder 3. With the discharge port 5 open, the continuous airflow into the discharge cylinder 3 is used to perform air purging. No additional cleaning equipment is needed, which can quickly achieve internal cleaning, prevent the residual soil conditioner from deteriorating, improve the quality of subsequent soil remediation, and achieve good results.

[0042] like Figure 1 and Figure 2 As shown, the movable support wheel 2 is fixedly installed inside the primary processing box 1. The bottom of the primary processing box 1 is fixedly connected to the discharge cylinder 3. The primary processing box 1 is equipped with a crushing roller.

[0043] The crushing roller performs primary crushing to prevent large volumes of soil conditioner from falling out of the discharge port 5. The movable support wheel 2 provides movable support and can be moved by raising the rear movable support wheel 2 and relying on the two sets of front movable support wheels 2 when needed.

[0044] like Figure 3 , Figure 6 and Figure 7 As shown, the fixed shaft 42 is fixedly connected to both ends of the rolling cylinder 41. Both fixed shafts 42 are rotatably sleeved with the discharge cylinder 3. The rolling cylinder 41 is located in the discharge port 5. The bottom of the rolling cylinder 41 is on the same horizontal plane as the bottom of the movable support wheel 2. Gear 1 43 is fixedly sleeved on the outer surface of a fixed shaft 42. An internal cavity is opened inside the rolling cylinder 41. The counterweight rod 44 is eccentrically fixed in the internal cavity. The cam assembly 11 includes a rotating shaft 111, a bearing 112, a second gear 113, and a cam 114. The bearing 112 is fixedly sleeved on the end of the discharge cylinder 3. One end of the rotating shaft 111 is sleeved inside the bearing 112. Gear 2 113 and cam 114 are both fixedly sleeved on the outer surface of the rotating shaft 111. Gear 2 113 meshes with gear 1 43.

[0045] The rotation of the rolling assembly 4 is achieved by the meshing of gear 1 43 and gear 2 113, thereby realizing the rotation of the cam assembly 11 and the corresponding rotation of the cam 114. The relative position of the rotation position of the cam 114 and the counterweight rod 44 inside the rolling cylinder 41 is adjusted and calibrated by the gear number matching, so as to ensure that when the counterweight rod 44 of the rolling cylinder 41 moves to the lower position, the cam 114 rotates to the upper position at the same time. The cam assembly 11 maintains stable rotation through the bearing 112.

[0046] like Figure 3 , Figure 8 and Figure 9As shown, the distribution assembly 13 includes a distribution cylinder 131, a first hole 132, a second hole 133, a third hole 134, a connecting sleeve 135, a bypass pipe 136, and a connecting pipe 137. The distribution cylinder 131 is fixedly connected to the top of the fixed cylinder 12, and the air supply pump 14 is fixedly installed on the top of the distribution cylinder 131. The first hole 132 is located on the left side of the outer surface of the distribution cylinder 131, and the second hole 133 and the third hole 134 are located on the right side of the outer surface of the distribution cylinder 131. The third hole 134, the first hole 132, and the second hole 133 are arranged spatially from top to bottom. The following are arranged in sequence: the air outlet of the air pump 14 is connected to the first hole 132; the connecting sleeve 135 is fixedly connected to the outer surface of the distribution cylinder 131 and is connected to the second hole 133; the bypass pipe 136 is fixedly connected to the outer surface of the distribution cylinder 131 and is connected to the third hole 134; the other end of the bypass pipe 136 is fixedly connected to the discharge cylinder 3 and is connected to the inside of the discharge cylinder 3; the connecting pipes 137 are symmetrically distributed on both sides of the connecting sleeve 135 and are connected to the connecting sleeve 135; the other end of the connecting pipe 137 is fixedly connected to the outer side of the discharge cylinder 3. The outer surface of the discharge cylinder 3 has a through hole 8, and the two ends of the through hole 8 are respectively connected to the connecting arc cavity 7 and the connecting pipe 137. The sealing assembly 15 includes a push block 151, a push rod 152, a movable plug 153, a spring 154, a first groove 155 and a second groove 156. One end of the spring 154 is fixedly connected to the inside of the distribution cylinder 131, and the other end of the spring 154 is fixedly connected to the movable plug 153. The movable plug 153 is movably sleeved inside the distribution cylinder 131. The upper end of the push rod 152 is fixedly connected to the bottom of the movable plug 153. The lower end of rod 152 passes through fixed cylinder 12 and extends into the interior of fixed cylinder 12 and is fixedly connected to push block 151. First groove 155 is opened on the right side of the outer surface of movable plug 153. Second groove 156 is opened inside push rod 152. The upper end of second groove 156 is connected to first groove 155. The lower end of second groove 156 passes through the outer surface of push rod 152. An adapter groove is opened at the bottom of fixed cylinder 12. The inner surface of adapter groove is rotatably sleeved with cam 114. Cam 114 is located at the bottom of push block 151 and is always in contact with push block 151.

[0047] By utilizing the position of the movable plug 153 in the sealing assembly 15 on the distribution cylinder 131, in conjunction with the positions of the first hole 132, the second hole 133, and the third hole 134, it is ensured that when the movable plug 153 moves upward, the first hole 132 and the second hole 133 are connected individually, while when the movable plug 153 moves downward, the first hole 132 and the third hole 134 are connected individually. This achieves the switching of the air outlet direction. Under the former airflow, the outlet 5 is sealed and the rolling assembly 4 is expanded, while under the latter airflow, the discharge direction is switched. The internal purging of cylinder 3, and the first groove 155 and the second groove 156 in the sealing assembly 15 ensure that when the inflation of the elastic airbag 10 is cancelled, the elastic airbag 10 can actively discharge the internal gas to complete the reset, realize the opening of the discharge port 5 and the reset of the opening and closing door 9. The elasticity of the spring 154 ensures that the push block 151 is always in contact with the cam 114 to complete the up and down position control. The fixed cylinder 12 is provided with a sealing sleeve and is located outside the push rod 152 to achieve dynamic sealing and ensure that the gas is not leaked when it is fed in from below.

[0048] A method for repairing soil remediation devices used for soil and water conservation includes the following repair steps:

[0049] Step 1: Before the repair, put the soil conditioner to be repaired into the primary treatment box 1, so that the device is placed on the soil area to be repaired. Start the crushing roller in the primary treatment box 1 to crush the soil conditioner and let it fall into the discharge cylinder 3, pushing the device forward. The fallen soil conditioner falls out along the gap between the rolling drum 41 and the discharge port 5 at the bottom of the discharge cylinder 3, so that the soil conditioner is evenly fed.

[0050] Step 2: As the pushing device moves forward, the air supply pump 14 is activated, and gas is introduced into the distribution component 13. With the rotation of the rolling component 4, the rotating gear 43 drives the meshing cam component 11 to rotate, causing the cam 114 in the cam component 11 to rotate continuously. When the cam 114 rotates to the top, it pushes the push block 151, push rod 152, and movable plug 153 in the sealing component 15 upwards and compresses the spring 154. At this time, the movable plug 153 moves above the first hole 132. The air supply pump 14 then introduces gas through the first hole 132, the second hole 133, the connecting sleeve 135, the connecting pipe 137, and the through hole 8 into the connecting arc cavity 7, thereby rapidly introducing gas into the elastic airbag 10. As the elastic airbag 10 inflates... The arc-shaped opening and closing door 9 in the assembly arc groove 6 is pushed outward along the assembly arc groove 6 and impacts the rolling cylinder 41. When the cam 114 rotates to the bottom, the movable plug 153 is located below the first hole 132 and seals the second hole 133. The air supplied by the air supply pump 14 enters the interior of the discharge cylinder 3 along the first hole 132, the third hole 134 and the bypass pipe 136. The elastic airbag 10 elastically contracts, and the previously introduced gas bypasses along the connecting pipe 137, the connecting sleeve 135, the second hole 133, the first groove 155 and the second groove 156. The contracted and restored elastic airbag 10 drives the opening and closing door 9 to reset and move into the assembly arc groove 6. As the cam 114 rotates continuously, the opening and closing door 9 intermittently impacts the rolling cylinder 41, and the blocked soil conditioner is vibrated and falls out smoothly.

[0051] Step 3: When the soil conditioner needs to be paused or stopped during the process, as it moves to the target stop position, the device is slightly lifted up, so that the rolling component 4 in the device is briefly removed from the soil and suspended in the air. At this time, the center of gravity of the rolling component 4 is deflected by the internal counterweight rod 44, so that the position of the counterweight rod 44 in the rolling cylinder 41 swings quickly and automatically to the vertical downward. As the rolling cylinder 41 deflects quickly, the cam component 11 is driven to deflect quickly through the gear 43, so that the cam 114 swings quickly to the top of the protrusion and maintains the state of pushing the sealing component 15, so that the movable plug 153 is kept above the first hole 132, and the air supply pump 14 is kept in the state of inputting gas into the elastic air bag 10. At this time, the expanded elastic air bag 10 pushes the opening and closing door 9 to extend outward and presses tightly against the outer surface of the rolling cylinder 41. The discharge port 5 is automatically locked, stopping the material from falling. After a brief lifting and automatic sealing, the device is slowly lowered to maintain the stopped material falling state.

[0052] Step 4: When it is necessary to clean the inside of the device, push the device to make the rolling component 4 roll, and keep the cam 114 rotating and located at the bottom. At this time, the movable plug 153 is located below the first hole 132 and seals the second hole 133. The air supplied by the air pump 14 enters the inside of the discharge cylinder 3 through the first hole 132, the third hole 134 and the bypass pipe 136, and the flowing air in the discharge cylinder 3 blows the inside of the discharge cylinder 3 to complete the blowing and cleaning.

8. The remediation method of a soil remediation device for soil and water conservation according to claim 7, characterized in that: The following repair steps are included: Step 1: Before the repair, put the soil conditioner to be repaired into the primary treatment box (1) and place the device on the soil area to be repaired. Start the crushing roller in the primary treatment box (1) so that the soil conditioner is crushed and falls into the discharge cylinder (3). Push the device forward and the fallen soil conditioner falls out along the gap between the rolling cylinder (41) and the discharge port (5) at the bottom of the discharge cylinder (3) to uniformly feed the soil conditioner. Step 2: As the pushing device moves forward, the air supply pump (14) is activated, and gas is introduced into the distribution assembly (13). As the rolling assembly (4) rotates, the rotating gear 1 (43) drives the meshing cam assembly (11) to rotate, causing the cam (114) in the cam assembly (11) to rotate continuously. When the cam (114) rotates to the top, it pushes the push block (151), push rod (152), and movable plug (153) in the sealing assembly (15) to move upward and compress the spring (154). At this time, the movable plug (153) moves above the first hole (132). At this time, the air supply pump (14) introduces gas into the connecting arc cavity (7) through the first hole (132), the second hole (133), the connecting sleeve (135), the connecting pipe (137), and the through hole (8), thereby allowing the gas to quickly enter the elastic airbag (10). As the elastic airbag (10) inflates, the pushing... The arc-shaped opening and closing door (9) in the moving assembly arc groove (6) moves outward along the assembly arc groove (6) and collides with the rolling cylinder (41). When the cam (114) rotates to the bottom, the movable plug (153) is located below the first hole (132) and seals the second hole (133). The air supplied by the air supply pump (14) enters the interior of the discharge cylinder (3) along the first hole (132), the third hole (134) and the bypass pipe (136), while the elastic gas The bladder (10) contracts elastically, and the previously introduced gas flows out along the connecting pipe (137), connecting sleeve (135), second hole (133), first groove (155) and second groove (156). The elastic bladder (10) that has recovered from contraction drives the opening and closing door (9) to reset and move into the assembly arc groove (6). As the cam (114) rotates continuously, the opening and closing door (9) intermittently hits the rolling cylinder (41), and the blocked soil conditioner falls out smoothly after vibration. Step 3: When the soil conditioner application process needs to be paused or stopped, as the device moves to the target stopping position, it is slightly lifted, causing the rolling component (4) in the device to briefly detach from the soil and suspend in the air. At this time, the rolling component (4) is deflected by the center of gravity of the internal counterweight rod (44), causing the counterweight rod (44) in the rolling cylinder (41) to swing rapidly and automatically to the vertical position. As the rolling cylinder (41) deflects rapidly, the cam component (11) is driven to deflect rapidly through the gear (43), causing the cam (11) to deflect rapidly. 4) Quickly swing until the protrusion is above and keep pushing the sealing assembly (15) so that the movable plug (153) is kept above the first hole (132) and the air supply pump (14) is kept supplying gas to the elastic airbag (10). At this time, the expanded elastic airbag (10) pushes the opening and closing door (9) to extend outward and tightly presses against the outer surface of the rolling cylinder (41). The discharge port (5) automatically locks and stops the material from falling. After a brief lifting and automatic closing, the device is slowly lowered to maintain the stopped material-falling state. Step 4: When it is necessary to clean the inside of the device, push the device to make the rolling component (4) roll and keep the cam (114) rotating and located at the bottom. At this time, the movable plug (153) is located below the first hole (132) and seals the second hole (133). The air supplied by the air pump (14) enters the inside of the discharge cylinder (3) along the first hole (132), the third hole (134) and the bypass pipe (136).
