Description

Technical Field

[0001] The present invention relates to the technical field of soil remediation, and specifically to a land ecological remediation structure capable of multi-layer mixed remediation. Background Art

[0002] As is well known, land ecological remediation refers to the process of stopping human interference in the ecosystem to reduce the load pressure, relying on the self-regulation ability and self-organization ability of the ecosystem to evolve it in an orderly direction, or using this self-recovery ability of the ecosystem supplemented by artificial measures to gradually restore the damaged ecosystem or make the ecosystem develop in a virtuous cycle direction, and repairing problems such as declining soil fertility, degraded ecological functions, land damage, vegetation damage, soil erosion, and environmental pollution. For example, through measures such as land leveling, soil improvement, and vegetation reconstruction, the ecological functions are restored so that it can be reused for agriculture, forestry, ecological tourism, etc.

[0003] The problems existing in the prior art are as follows: During the land remediation process, due to different usage scenarios of the land, for example, when applying drugs after loosening the soil in farmland, the depth of the soil layer that needs to be excavated is relatively deep, while for the land damaged by mining such as mines, it can be relatively shallow. However, it is difficult for small land remediation structures in the prior art to avoid the above problems at the same time. Moreover, due to the large possible differences in the positions of the remediated land, it is difficult for the vehicles in the prior art to drive smoothly. At the same time, the soil conditioning liquid sprayed may only cover the surface of the transported soil and it is difficult to be evenly mixed with the soil, making it inconvenient to use.

[0004] Based on the above-mentioned problems, we found that it is difficult for the soil ecological remediation structures in the prior art to avoid the above problems at the same time. Therefore, we propose a land ecological remediation structure capable of multi-layer mixed remediation that reduces the dependence on towing vehicles, can adjust the loosening actions of soil layers at different depths as needed, can evenly spray the liquid medicine, and can evenly lay coverings such as wheat straw and hay on the soil surface after loosening to facilitate moisture preservation. Summary of the Invention

[0005] (I) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the present invention provides a land ecological remediation structure capable of multi-layer mixed remediation, which has the advantages of reducing the dependence on towing vehicles, being able to adjust the loosening actions of soil layers at different depths as needed, being able to evenly spray the liquid medicine, and being able to evenly lay coverings such as wheat straw and hay on the soil surface after loosening to facilitate moisture preservation.

[0007] (II) Technical Solutions

[0008] The above technical objectives of the present invention are achieved through the following technical solutions: a land ecological restoration structure capable of multi-layer mixed restoration, comprising a main frame and a vehicle body installed outside the main frame, a chassis frame is fixedly connected to the inner side of the main frame, a layer frame is fixedly connected to the inner side of the chassis frame, a laying box is fixedly connected to the right side of the main frame, and a loosening component is fixedly connected to the left side of the inner side of the chassis frame;

[0009] The loosening assembly includes a crossbeam fixedly connected to the left side of the inner side of the chassis frame and a rotating shaft rotatably connected to the inner side of the chassis frame, the front and rear sides of the outer side of the rotating shaft are rotatably connected to an adjusting frame, the right side of the inner side of the adjusting frame is rotatably connected to a hollow main shaft, the outer side of the hollow main shaft is fixedly connected to a loosening rake, the right side of the crossbeam is rotatably connected to a telescopic cylinder, the telescopic end of the telescopic cylinder is rotatably connected to the top of the adjusting frame, a loosening motor is installed on the rear side of the front adjusting frame, the inner side of the adjusting frame is rotatably connected to a connecting shaft, the connecting shaft and the output end of the loosening motor are meshed and connected by gears, and the front and rear sides of the connecting shaft are transmission-connected to the hollow main shaft through a transmission pulley and a transmission belt.

[0010] By adopting the above technical solution, a vehicle body is provided to cooperate with the main frame, and the main frame serves as a structural support. The vehicle body can be used to facilitate the movement of the equipment, so as to facilitate the repair of the land on the way. When in use, the loosening motor of the loosening component can drive the hollow main shaft to rotate through the connecting shaft. While rotating, the loosening rake on the outside of the hollow main shaft will loosen the ground. According to different usage scenarios, when it is necessary to loosen different soil depths, the telescopic cylinder on the right side of the beam can be used to push and pull the adjusting frame. At this time, the adjusting frame and the hollow main shaft connected thereto will rotate along the rotating shaft and descend or rise in an arc shape, so that the loosening rake can be flexibly adjusted according to the required scenario.

[0011] The present invention is further configured as follows: a partition is fixedly connected between the two adjustment frames, a force-bearing frame is fixedly connected to the right side of the partition, and a distribution sleeve is fixedly connected to the right side of the force-bearing frame.

[0012] The above technical solution is adopted to set up a partition to separate the space between the two adjustment frames to prevent the sand raised by the loosening rake from covering the loosening motor, causing the transmission components to be unable to be used normally or affecting the normal heat dissipation of the equipment. The distribution sleeve is used to cooperate with the force frame to provide auxiliary support to the hollow main shaft so that it can rotate reasonably.

[0013] The present invention is further configured as follows: a medicine box is fixedly connected to the top of the shelf, a pump is fixedly connected to the top of the shelf, an input end of the pump is connected to the medicine box, and an output section of the pump is fixedly connected to a connecting hose.

[0014] With the above technical solution, by setting up a medicine box for storing soil remediation agents or regulators, the agent can be pumped out by a pump and then input into the hollow main shaft through a connecting hose, and sprayed onto the soil turned by the loosening harrow through the holes on the surface of the hollow main shaft. Since the spraying action and the soil loosening and turning are carried out simultaneously, the agent and the soil can be mixed more evenly.

[0015] The present invention is further configured as: a sealing member is provided inside the distribution sleeve, the inside of the distribution sleeve is rotatably connected to the hollow main shaft, and the top of the distribution sleeve is fixedly connected to the connecting hose.

[0016] With the above technical solution, by setting up a sealing member, it is used to improve the sealing performance between the distribution sleeve and the hollow main shaft, avoiding a large amount of liquid leakage and other situations in the structure. At the same time, the distribution sleeve is used to communicate with the connecting hose at the output end of the pump to facilitate the supply of the liquid medicine into the hollow main shaft.

[0017] The present invention is further configured as: protective tubes are fixedly connected to the top of the distribution sleeve and the right side of the shelf, and the protective tubes are arranged outside the connecting hose.

[0018] With the above technical solution, by setting up the protective tube in cooperation with the connecting hose, it is convenient to protect the connecting hose. When the position of the connecting hose changes due to the hollow main shaft, it will also be bent or stretched to a certain extent. The protective tube can limit the position of the connecting hose to avoid collision with the structure, and at the same time, it can prevent the loosening harrow from winding or scratching the hose during rotation.

[0019] The present invention is further configured as: the bottom of the laying box is in a funnel shape, a rotating shaft is rotatably connected to the bottom inside the laying box, a rotating blade is fixedly connected to the outside of the rotating shaft, and a pressing cover is movably connected to the inside of the laying box.

[0020] With the above technical solution, by setting up the funnel-shaped laying box, it is convenient to store coverings such as wheat straw and hay when needed, and make them fall along the funnel-shaped guide to the narrower bottom of the laying box when not affected by external forces. And the top of the laying box is blocked by the pressing cover. When the rotating shaft rotates inside the laying box, the rotating blade on its outside will stir the covering on the top and pull it to the bottom of the laying box, and it will fall when it is in the air and cover the bottom soil, ensuring uniform laying during continuous operation.

[0021] The present invention is further configured as: upward frames are fixedly connected to the front side and the rear side of the laying box, a limiting telescopic rod is fixedly connected to the bottom of the upward frame, the bottom of the limiting telescopic rod is fixedly connected to the pressing cover, and a pressing spring is sleeved outside the limiting telescopic rod.

[0022] With the above technical solution, by setting up the upper frame in cooperation with the limit telescopic rod, it is convenient to cooperate with the pressing spring to keep the pressing cover in a downward pressing state all the time, so as to press against the covering object, making it receive a downward moving force, avoiding situations such as jamming and resulting in abnormal use. And the limit telescopic rod can limit the deformation of the pressing spring, avoiding difficult reset caused by radial deformation.

[0023] The present invention is further configured as: the pressing cover includes two plates. A rotating shaft is fixedly connected to the inner side of the left plate. The outer side of the rotating shaft is rotatably connected to the right plate. A torsion spring is sleeved on the outer side of the rotating shaft. Two ends of the torsion spring are respectively fixedly connected to the left plate and the right plate;

[0024] A sliding frame is fixedly connected to the top of the left plate. A sliding pin is slidably connected to the inner side of the sliding frame. An inserting frame for cooperating with the sliding pin is fixedly connected to the top of the right plate.

[0025] With the above technical solution, when it is necessary to add the covering object, the right plate will naturally open due to the elasticity of the torsion spring. At this time, the entire pressing cover can be lifted upward to facilitate the delivery of the covering object from the bottom opening of the right plate. After the addition is completed, the right plate can be rotated along the rotating shaft to be parallel to the left plate, and the sliding pin slides from the inner side of the sliding frame to the inner side of the inserting frame to complete the fixation of the structure, avoiding the two plates from resetting due to the rebound of the torsion spring and resulting in no squeezing effect.

[0026] The present invention is further configured as: a shaft seat is fixedly connected to the top of the total frame. An auxiliary shaft is rotatably connected to the inner side of the shaft seat. The outer side of the auxiliary shaft is connected to the dial shaft through a transmission belt pulley and a conveyor belt. A reduction motor is fixedly connected to the top of the layer frame. The output end of the reduction motor is fixedly connected to a stirring shaft. The right side of the medicine box is rotatably connected to the stirring shaft through an oil seal. The outer side of the stirring shaft is connected to the auxiliary shaft through a transmission belt pulley and a conveyor belt.

[0027] With the above technical solution, by setting up the shaft seat to support the auxiliary shaft and enable it to rotate, when the reduction motor drives the stirring shaft to rotate, the oil liquid inside the medicine box can be kept mixed to avoid precipitation and stratification. And during this process, the auxiliary shaft connected to it through the transmission belt pulley and the conveyor belt will also rotate and transmit the power to the inside of the dial shaft to facilitate driving the dial shaft to rotate together.

[0028] The present invention is further configured as: the vehicle body is composed of an engine part installed on the top of the total frame, a wheel part installed on the left bottom of the total frame, a crawler part installed on the front and rear sides of the total frame, and a crawler wheel transmission part installed on the inner right side of the total frame.

[0029] By adopting the above technical solution, by setting a semi-tracked vehicle body, the traction force and stability for normal movement on different terrains can be provided, adapting to complex terrain conditions, including but not limited to soft sandy land, muddy wetland or rugged mountainous land. The wheel part can provide better driving speed and flexibility on relatively flat roads, facilitating the transfer of the equipment between different sites.

[0031] Compared with the prior art, the present invention provides a land ecological restoration structure capable of multi-layer mixed restoration, having the following beneficial effects:

[0032] For the land ecological restoration structure capable of multi-layer mixed restoration, by setting the vehicle body in cooperation with the main frame, the main frame serves as the support of the structure, and the vehicle body can facilitate the movement of the equipment, so as to perform restoration operations on the land passed by during the journey. When in use, the loosening motor of the loosening component can drive the hollow main shaft to rotate through the connecting shaft. While rotating, the loosening rake on the outer side of the hollow main shaft will loosen the ground. When it is necessary to loosen different soil layers according to different usage scenarios, the telescopic cylinder on the right side of the cross beam can push and pull the adjusting frame. At this time, the adjusting frame and the hollow main shaft connected thereto will rotate along the rotating shaft and descend or rise in an arc shape, so that the loosening rake can be flexibly adjusted according to the required scenario.

[0046] By arranging the vehicle body 2 to cooperate with the main frame 1, the main frame 1 serves as the support of the structure, and the vehicle body 2 facilitates the movement of the equipment, so as to repair the land along the way during travel. When in use, the loosening motor 67 of the loosening assembly 6 can drive the hollow main shaft 64 to rotate through the connecting shaft 68. While rotating, the loosening harrow 65 on the outer side of the hollow main shaft 64 will loosen the ground. When it is necessary to loosen different soil layers according to different usage scenarios, the telescopic cylinder 66 on the right side of the cross beam 61 can push and pull the adjusting frame 63. At this time, the adjusting frame 63 and the hollow main shaft 64 connected thereto will rotate along the rotating shaft 62 and descend or rise in an arc shape, so that the loosening harrow 65 can be flexibly adjusted according to the required scenario.

[0047] Among them, a partition plate 7 is fixedly connected between two adjusting frames 63. A force-bearing frame 8 is fixedly connected to the right side of the partition plate 7. A distribution sleeve 9 is fixedly connected to the right side of the force-bearing frame 8. By providing the partition plate 7, it is used to separate the space between the two adjusting frames 63, preventing the sandy soil lifted by the loosening harrow 65 from covering the loosening motor 67, which may cause the transmission components to malfunction or affect the normal heat dissipation of the equipment. The provided distribution sleeve 9 is used to cooperate with the force-bearing frame 8 to assist in supporting the hollow main shaft 64, enabling it to rotate reasonably. A medicine box 10 is fixedly connected to the top of the layer rack 4. A pump 11 is fixedly connected to the top of the layer rack 4. The input end of the pump 11 is communicated with the medicine box 10. The output section of the pump 11 is fixedly connected with a connecting hose 12. By providing the medicine box 10, it is used to store soil repair agents or regulators, and the medicine can be pumped by the pump 11 and input into the hollow main shaft 64 through the connecting hose 12, and then sprinkled onto the soil turned by the loosening harrow 65 through the holes on the surface of the hollow main shaft 64. Since the sprinkling action and the soil loosening and turning are carried out simultaneously, the medicine and the soil can be mixed more evenly. A sealing member 13 is provided inside the distribution sleeve 9. The inside of the distribution sleeve 9 is rotatably connected to the hollow main shaft 64. The top of the distribution sleeve 9 is fixedly connected to the connecting hose 12. By providing the sealing member 13, it is used to improve the sealing performance between the distribution sleeve 9 and the hollow main shaft 64, preventing a large amount of liquid leakage and other situations from occurring in the structure. At the same time, the distribution sleeve 9 is used to communicate with the connecting hose 12 at the output end of the pump 11 to facilitate the supply of liquid medicine into the hollow main shaft 64. Protection tubes 14 are fixedly connected to the top of the distribution sleeve 9 and the right side of the layer rack 4. The protection tubes 14 are arranged outside the connecting hose 12. By providing the protection tubes 14 in cooperation with the connecting hose 12, it is convenient to protect the connecting hose 12. When the position of the connecting hose 12 changes due to the movement of the hollow main shaft 64, it will also be bent or stretched to a certain extent. The protection tubes 14 can limit the position of the connecting hose 12, preventing it from colliding with the structure, and at the same time preventing the loosening harrow 65 from winding or scratching the hose during rotation. The vehicle body 2 includes an engine part installed on the top of the main frame 1, a wheel part installed at the bottom left of the main frame 1, a crawler part installed on the front and rear sides of the main frame 1, and a crawler wheel transmission part installed on the right side inside the main frame 1. By providing the semi-crawler vehicle body 2, it can provide the stability for normal movement on different terrains and adapt to complex terrain conditions, including but not limited to soft sandy land, muddy wetlands or rugged mountains. The wheel part can provide better driving speed and flexibility on relatively flat roads, facilitating the transfer of the equipment between different sites.

[0048] Working principle of this embodiment: According to the land use scenario and restoration requirements, the telescopic cylinder 66 on the right side of the cross beam 61 is activated. The telescopic end of the telescopic cylinder 66 pushes and pulls the adjusting frame 63, causing the adjusting frame 63 and the hollow main shaft 64 to rotate along the rotating shaft 62, descending or rising in an arc, and adjusting the loosening harrow 65 to an appropriate depth of the loosened soil layer. Subsequently, the loosening motor 67 is turned on. The loosening motor 67 drives the connecting shaft 68 to rotate through gear meshing. The connecting shaft 68 then drives the hollow main shaft 64 to rotate through a belt pulley and a transmission belt. The loosening harrow 65 outside the hollow main shaft 64 accordingly loosens the ground soil. While loosening, the pump 11 is started. The pump 11 extracts the soil repair agent or regulator from the medicine box 10, inputs the liquid medicine into the distribution sleeve 9 through the connecting hose 12, and then transports it to the inside of the hollow main shaft 64 through the distribution sleeve 9. Finally, it is sprinkled onto the soil stirred by the loosening harrow 65 through the holes on the surface of the hollow main shaft 64, realizing the uniform mixing of the liquid medicine and the soil. During this process, the vehicle body 2 keeps moving, so that the traveling route can cover as much of the entire restoration area as possible.

[0049] Embodiment 2

[0050] Reference Figure 1-8 , a land ecological restoration structure capable of multi-layer mixed restoration further includes a laying box 5. Among them, the bottom of the laying box 5 is in a funnel shape. A dial shaft 15 is rotatably connected to the bottom inside the laying box 5. A dial piece 16 is fixedly connected to the outside of the dial shaft 15. A pressing cover 17 is movably connected to the inside of the laying box 5;

[0051] By setting the funnel-shaped laying box 5, it is convenient to store coverings such as wheat straw and dry grass when needed, and make them fall along the funnel-shaped guide to the narrower bottom of the laying box 5 when not affected by external forces. And the top of the laying box 5 is blocked by the pressing cover 17 at the top. When the dial shaft 15 rotates inside the laying box 5, the dial piece 16 on its outside will stir the top covering and pull it to the bottom of the laying box 5, and it will fall when it is in the air, covering the bottom soil, and ensuring uniform laying during continuous operation.

[0052] Wherein, upper frames 18 are fixedly connected to both the front side and the rear side of the laying box 5. A limiting telescopic rod 19 is fixedly connected to the bottom of the upper frame 18. The bottom of the limiting telescopic rod 19 is fixedly connected to the pressing cover 17. A pressing spring is sleeved outside the limiting telescopic rod 19. By arranging the upper frame 18 in cooperation with the limiting telescopic rod 19, it is convenient to make the pressing cover 17 always in a downward pressing state in cooperation with the pressing spring, so as to press the covering material, so that it receives a downward moving force, and avoid situations such as jamming that may cause abnormal use. The limiting telescopic rod 19 can limit the deformation of the pressing spring to prevent difficult reset caused by radial deformation. The pressing cover 17 includes two plates 171. A rotating shaft 172 is fixedly connected to the inner side of the left plate 171. The outside of the rotating shaft 172 is rotatably connected to the right plate 171. A torsion spring 173 is sleeved outside the rotating shaft 172. The two ends of the torsion spring 173 are respectively fixedly connected to the left plate 171 and the right plate 171. A sliding frame 20 is fixedly connected to the top of the left plate 171. A sliding pin 21 is slidably connected to the inside of the sliding frame 20. An inserting frame 22 used in cooperation with the sliding pin 21 is fixedly connected to the top of the right plate 171. When it is necessary to add the covering material, the right plate 171 will naturally open due to the elasticity of the torsion spring 173. At this time, the entire pressing cover 17 can be lifted upward to facilitate the delivery of the covering material from the bottom opening of the right plate 171. After the addition is completed, the right plate 171 can be rotated along the rotating shaft 172 to be parallel to the left plate 171, and the sliding pin 21 slides from the inside of the sliding frame 20 to the inside of the inserting frame 22 to complete the fixation of the structure, and avoid the two plates 171 from resetting due to the rebound of the torsion spring 173 and failing to achieve the extrusion effect. A shaft seat 23 is fixedly connected to the top of the main frame 1. An auxiliary shaft 24 is rotatably connected to the inside of the shaft seat 23. The outside of the auxiliary shaft 24 is connected to the dial shaft 15 through a belt pulley and a conveyor belt. A reduction motor 25 is fixedly connected to the top of the layer rack 4. The output end of the reduction motor 25 is fixedly connected to a stirring shaft 26. The right side of the medicine box 10 is rotatably connected to the stirring shaft 26 through a oil seal. The outside of the stirring shaft 26 is connected to the auxiliary shaft 24 through a belt pulley and a conveyor belt. By arranging the shaft seat 23, it is used to support the auxiliary shaft 24 and enable it to rotate. When the reduction motor 25 drives the stirring shaft 26 to rotate, the oil liquid inside the medicine box 10 can be kept mixed to avoid precipitation and stratification. During this process, the auxiliary shaft 24 connected to it through a belt pulley and a conveyor belt will also rotate and transmit the power to the inside of the dial shaft 15 to facilitate driving the dial shaft 15 to rotate together.

[0053] Working principle of this embodiment: when a covering needs to be added during operation, due to the elastic effect of the torsion spring 173, the right plate 171 of the pressure cover 17 is naturally opened, the entire pressure cover 17 is moved up, and the covering is placed from the bottom opening of the right plate 171, and then the right plate 171 is rotated along the rotation axis 172 to be parallel to the left plate 171, and the sliding pin 21 is slid from the inside of the slide 20 to the inside of the insertion frame 22 to fix the pressure cover 17, so as to prevent the torsion spring 173 from rebounding and causing the plate 171 to be reset and unable to squeeze the covering. The reduction motor 25 drives the stirring shaft 26 to rotate, stirs and mixes the oil in the medicine box 10 to prevent it from settling and stratifying. At the same time, the power is transmitted to the auxiliary shaft 24 through the transmission pulley and the conveyor belt. The auxiliary shaft 24 then transmits the power to the dial shaft 15 through the transmission pulley and the conveyor belt, so that the dial shaft 15 starts to rotate. When the dial shaft 15 rotates, the paddle 16 on its outside moves the covering on the top of the laying box 5 and pulls it to the bottom of the laying box 5. The covering falls down when it is suspended in the air and evenly covers the bottom soil.

After reading this specification, those skilled in the art can make non-creative modifications to the present embodiment as needed. Although the embodiments of the present invention have been shown and described, it is understandable to those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
