Description

Technical Field

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

[0002] As we all know, land ecological restoration refers to stopping human interference in the ecosystem to reduce the load pressure, relying on the self-regulation and self-organization ability of the ecosystem to make it evolve in an orderly direction, or using the self-recovery ability of the ecosystem, supplemented by artificial measures, to gradually restore the damaged ecosystem or make the ecosystem develop in the direction of a benign cycle. It is a process of repairing problems such as land fertility decline, ecological function degradation, land destruction, vegetation damage, soil erosion and environmental pollution. For example, through measures such as land leveling, soil improvement, and vegetation reconstruction, the ecological function is restored so that it can be used again for agriculture, forestry, ecotourism and other purposes.

[0003] The problems with the existing technology are: during the land restoration process, due to the different land use scenarios, for example, the depth of the soil layer to be excavated when loosening and then applying drugs to farmland needs to be deeper, while the depth of the soil layer to be excavated in mining and other mining areas can be relatively shallow. However, it is difficult for the small and medium-sized land restoration structures in the existing technology to avoid the above problems at the same time. Moreover, since the location of the repaired land may vary greatly, it is difficult for the vehicles in the existing technology to travel smoothly. At the same time, the soil conditioning liquid applied may only cover the surface of the soil after transportation and is difficult to mix evenly with the soil, which is inconvenient to use.

[0004] Based on the above-mentioned problems, we found that it is difficult for the existing soil ecological restoration structure to avoid the above problems at the same time. Therefore, we proposed a multi-layer mixed restoration land ecological restoration structure that reduces dependence on traction vehicles, can adjust the loosening action of soil layers of different depths as needed, and can evenly spread the liquid medicine. At the same time, after loosening, straw, hay and other covering materials can be evenly laid on the soil surface to facilitate moisture conservation. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In response to the shortcomings of the existing technology, the present invention provides a land ecological restoration structure that can be repaired with multiple layers of mixed materials. It has the advantages of reducing dependence on traction vehicles, being able to adjust the loosening action of soil layers of different depths as needed, and being able to evenly spread the liquid medicine. At the same time, after loosening, covering materials such as wheat straw and hay can be evenly laid on the soil surface to facilitate moisture conservation.

[0007] (2) Technical solution

[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 mounted on the outside of the main frame, a chassis frame fixedly connected to the inside of the main frame, a layer frame fixedly connected to the inside of the chassis frame, a laying box fixedly connected to the right side of the main frame, and a loosening component fixedly connected to the left side of the inside 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 with 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] The above technical solution is adopted, by setting a vehicle body to cooperate with the main frame, the main frame serves as the support of the structure, and 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 adjustment frame. At this time, the adjustment frame and the hollow main shaft connected to it 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 by setting 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 use 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, the input end of the pump is connected to the medicine box, and the output section of the pump is fixedly connected to a connecting hose.

[0014] By adopting the above technical solution, a medicine box is set up to store soil remediation agents or regulators, and the agents can be extracted by a pump and then input into the hollow main shaft through a connecting hose, and then sprinkled into the soil turned by the loosening harrow through the holes on the surface of the hollow main shaft. Since the sprinkling action and the soil loosening and turning are carried out simultaneously, the agent and soil can be mixed more evenly.

[0015] The present invention is further configured as follows: a sealing member is provided on the inner side of the distribution sleeve, the inner side 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] The above technical solution is adopted, by setting a seal to improve the sealing between the distribution sleeve and the hollow main shaft, thereby avoiding large-scale leakage of the structure. At the same time, the distribution sleeve is used to connect with the connecting hose at the output end of the pump to facilitate the supply of liquid medicine to the hollow main shaft.

[0017] The present invention is further configured as follows: a top of the distribution sleeve and the right side of the shelf are both fixedly connected with a protective tube, and the protective tube is arranged on the outside of the connecting hose.

[0018] By adopting the above technical solution, a protective tube is provided in combination with the connecting hose, so that the connecting hose can be protected. When the connecting hose changes position due to the hollow main shaft, it will also bend or stretch to a certain extent. The protective tube can limit the position of the connecting hose to avoid collision with the structure. At the same time, it can prevent the loosening rake from causing entanglement or scratching of the hose when rotating.

[0019] The present invention is further configured as follows: the bottom of the laying box is configured as a bucket shape, the bottom inside the laying box is rotatably connected to a shift shaft, the outside of the shift shaft is fixedly connected to a shift piece, and the inside of the laying box is movably connected to a pressure cover.

[0020] By adopting the above technical solution and setting up a bucket-shaped laying box, it is convenient to store covering materials such as wheat straw and hay when needed, and make them fall along the bucket-shaped guide to the narrow bottom of the laying box when not affected by external forces, and the top of the laying box is sealed by a pressure cover on the top. When the shift shaft rotates inside the laying box, the shift piece on the outside will shift the covering on the top and pull it to the bottom of the laying box. It falls when it is suspended in the air and covers the bottom soil, so that uniform laying can be guaranteed under continuous operation.

[0021] The present invention is further configured as follows: the front and rear sides of the laying box are fixedly connected to an upper frame, the bottom of the upper frame is fixedly connected to a limiting telescopic rod, the bottom of the limiting telescopic rod is fixedly connected to a pressure cover, and a pressure spring is sleeved on the outer side of the limiting telescopic rod.

[0022] By adopting the above technical solution, by setting up an upper frame in conjunction with a limiting telescopic rod, it is possible to cooperate with the pressure spring to keep the pressure cover in a downward pressure state at all times, so as to press the covering object and subject it to a downward force, thereby avoiding situations such as getting stuck and causing it to be unable to be used normally. The limiting telescopic rod can limit the deformation of the pressure spring to avoid radial deformation that makes it difficult to reset.

[0023] The present invention is further configured as follows: the gland includes two plates, the inner side of the left plate is fixedly connected to a rotating shaft, the outer side of the rotating shaft is rotatably connected to the right plate, the outer side of the rotating shaft is sleeved with a torsion spring, and the two ends of the torsion spring are respectively fixedly connected to the left plate and the right plate;

[0024] The top of the left plate is fixedly connected with a slide, the inner side of the slide is slidably connected with a slide pin, and the top of the right plate is fixedly connected with a plug-in frame used in conjunction with the slide pin.

[0025] With the above technical solution, when it is necessary to add a covering, the right side plate will naturally open due to the elasticity of the torsion spring. At this time, the entire pressure cover can be moved up to facilitate the placement of the covering from the bottom opening of the right side plate. After the addition is completed, the right side plate can be rotated along the rotating axis to be parallel to the left side plate, and the sliding pin can be used to slide from the inside of the slide to the inside of the insertion rack to complete the fixation of the structure, avoiding the two plates from being reset due to the rebound of the torsion spring, resulting in no extrusion effect.

[0026] The present invention is further configured as follows: the top of the main frame is fixedly connected to a shaft seat, the inner side of the shaft seat is rotatably connected to an auxiliary shaft, the outer side of the auxiliary shaft is connected to the dial shaft through a transmission pulley and a conveyor belt, the top of the shelf is fixedly connected to a reduction motor, 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, and the outer side of the stirring shaft is connected to the auxiliary shaft through a transmission pulley and a conveyor belt.

[0027] By adopting the above technical solution, a shaft seat is set to support the auxiliary shaft and enable it to rotate. When the reduction motor drives the stirring shaft to rotate, the oil inside the medicine box can be kept mixed to prevent its sedimentation and stratification. In this process, the auxiliary shaft connected to it through the transmission pulley and conveyor belt will also rotate and transmit power to the inner side of the dial shaft to drive the dial shaft to rotate together.

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

[0029] By adopting the above technical solution and setting up a semi-tracked vehicle body, it can provide traction and stability for normal movement on different terrains, adapting to complex terrain conditions, including but not limited to soft sand, muddy wetlands or rugged mountains. The wheel part can provide better driving speed and flexibility on relatively flat roads, making it convenient to transfer equipment between different sites.

[0030] (3) Beneficial effects

[0031] Compared with the existing technology, the present invention provides a land ecological restoration structure capable of multi-layer mixed restoration, which has the following beneficial effects:

[0032] The land ecological restoration structure capable of multi-layer mixed restoration is provided with a vehicle body and a general frame, the general frame serves as the support of the structure, and the vehicle body can be used to facilitate the movement of the equipment, so as to facilitate restoration operations on the land along 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. When it is necessary to loosen different soil depths according to different usage scenarios, the telescopic cylinder on the right side of the beam can be used to push and pull the adjustment frame. At this time, the adjustment 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.
