Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and in particular to a geological soil ecological restoration treatment device. Background Technology

[0002] With the accelerating pace of industrialization, land resources are increasingly polluted by heavy metals, organic pollutants, and other harmful substances, leading to a decline in ecological function, damage to soil structure, and serious impacts on agricultural production and environmental quality. To achieve sustainable use of land resources, it is necessary to scientifically and effectively remediate contaminated soil and enhance its physical and chemical properties and biological activity. Geological soil ecological remediation devices have been developed in this context, capable of removing pollutants, replenishing organic matter, and improving soil structure, and are widely used in farmland management, mining area reclamation, and ecological environment restoration.

[0003] In existing technologies, soil remediation treatment devices typically use a traction mechanism to drive the main unit, which works in conjunction with a plow to break up the soil, while a spraying assembly delivers a quantitative amount of remediation agent. Traditional spraying assemblies often employ fixed-angle nozzles or centrifugal disc diffusion structures, using fans or rotating discs to diffuse particulate or liquid remediation agents. The former results in a narrow coverage area and high overlap in the work zone, while the latter relies on high-speed rotation, which can easily cause the agent particles to settle in stages. Neither approach achieves the large-area uniform dispersion required for contaminated soil, necessitating repeated operations, increasing work time and energy consumption, reducing remediation efficiency, and hindering the efficient advancement of large-scale soil remediation projects. Tillage assemblies often use rigid supports for fixation, making it impossible to adjust the breaking depth in real time according to the degree of soil compaction, leading to incomplete treatment of hard soil layers or excessive turning over of loose soil. Summary of the Invention

[0004] To overcome the above deficiencies, this utility model provides a geological soil ecological restoration treatment device, which aims to expand the coverage of the restoration agent spraying and improve the efficiency of large-scale restoration projects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a geological soil ecological restoration treatment device, comprising a mobile frame, a hopper installed on the mobile frame, a discharge component, and a spraying component;

[0006] The discharge assembly includes a discharge trough located at the bottom of the hopper, a spiral conveying blade is provided in the discharge trough, one end of the spiral conveying blade is fixedly connected to the output end of the first drive motor, and a discharge pipe is connected to the other end of the discharge trough and the spiral conveying blade.

[0007] The spraying assembly includes a rotating shaft vertically disposed below the mobile frame and rotatably connected to the mobile frame. A conical nozzle is fixedly installed at the bottom of the rotating shaft. The inlet of the conical nozzle is connected to the discharge pipe. The rotating shaft is connected to a drive mechanism for driving the rotating shaft to reciprocate around its axis. An air inlet pipe for supplying high-pressure gas to the conical nozzle is connected to one side of the conical nozzle.

[0008] Furthermore, the drive mechanism includes a C-shaped connecting frame rotatably connected to the outer wall of the rotating shaft. The other end of the C-shaped connecting frame is connected to a ball joint. A second drive motor is fixedly connected to the bottom of the mobile frame. The output end of the second drive motor is connected to a turntable. A ball socket is eccentrically provided on the turntable. The ball joint is rotatably fitted into the ball socket. The second drive motor drives the turntable to rotate, thereby driving the rotating shaft and the conical nozzle to reciprocate through the ball socket, the ball joint, and the C-shaped connecting frame.

[0009] Furthermore, there are two hoppers, which are installed side by side on the mobile frame. The first drive motor is a dual-output shaft motor and is installed between the two hoppers. Each hopper has a spiral conveying blade in the discharge trough at the bottom. The inner ends of the two spiral conveying blades are fixedly connected to the two output shafts of the dual-output shaft motor, respectively. The discharge pipe is connected to the discharge troughs at the bottom of the two hoppers.

[0010] Furthermore, it also includes a soil-turning assembly disposed at the front end of the mobile frame. The soil-turning assembly includes a horizontally arranged connecting shaft, both ends of which are fixedly connected to the mobile frame. Multiple sleeve bases are rotatably sleeved on the connecting shaft at intervals, and multiple plow blades are fixedly connected to the outer wall of the sleeve bases in a circumferentially evenly distributed manner.

[0011] Furthermore, a fixing block is fixedly connected to the outer wall of the sleeve base corresponding to the position of each plow blade. The top of the fixing block has an inclined surface, and the root of the plow blade is connected to a connecting plate. The connecting plate has an elongated adjustment groove, and the inclined surface has a threaded hole. A locking bolt passes through the adjustment groove and is threadedly connected to the threaded hole on the inclined surface to lock the connecting plate onto the fixing block.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, by driving the conical nozzle to swing back and forth to form a fan-shaped coverage area, and at the same time using high-pressure gas to spray the remediation agent through the conical nozzle, the coverage area is greatly expanded compared with the fixed nozzle, effectively eliminating the overlapping area of ​​the work zone, and the remediation agent can be evenly covered in a single operation, thus improving the treatment efficiency of soil remediation.

[0014] 2. The plow blades achieve the effect of adjusting the length of the plow blades through the inclined surface-adjusting groove structure, which solves the problem of inconvenience in adjusting the plow blades when cultivating soil in different environments, and improves the convenience of the soil remediation device; the independently rotating sleeve base allows each set of plow blades to rotate adaptively with the terrain undulations, avoiding damage to the overall mechanism caused by impacts from hard objects.

[0015] 3. The parallel design of the dual hoppers, combined with the spiral conveyor blades for continuous material supply, enables uninterrupted delivery of the repair agent, improves the operating efficiency of a single unit, reduces the number of times the equipment travels back and forth, and lowers the overall energy consumption.

An air inlet pipe 10 for supplying high-pressure gas to the conical nozzle 8 is connected to one side of the conical nozzle 8.

[0029] In this embodiment, the driving mechanism includes a C-shaped connecting frame 12 rotatably connected to the outer wall of the rotating shaft 6. The other end of the C-shaped connecting frame 12 is connected to a ball joint 13. A second drive motor 7 is fixedly connected to the bottom of the mobile frame 1. The output end of the second drive motor 7 is connected to a turntable 9. A ball socket 11 is eccentrically provided on the turntable 9. The ball joint 13 is rotatably fitted into the ball socket 11. The second drive motor 7 drives the turntable 9 to rotate, thereby driving the rotating shaft 6 and the conical nozzle 8 to reciprocate through the ball socket 11, the ball joint 13, and the C-shaped connecting frame 12.

[0030] To improve the operating efficiency of a single device, in this embodiment, two hoppers 2 are provided, and the two hoppers 2 are installed side by side on the mobile frame 1. The first drive motor 3 is a dual-output shaft motor and is installed between the two hoppers 2. Each hopper 2 has a spiral conveying blade 4 in the discharge trough at the bottom. The inner ends of the two spiral conveying blades 4 are fixedly connected to the two output shafts of the dual-output shaft motor, respectively. The discharge pipe 5 is connected to the discharge trough at the bottom of the two hoppers 2.

[0031] To improve the adaptability of tillage, a tillage assembly is installed at the front end of the mobile frame 1. The tillage assembly includes a horizontally arranged connecting shaft 15. Both ends of the connecting shaft 15 are fixedly connected to the mobile frame 1. Multiple sleeve bases 14 are rotatably sleeved on the connecting shaft 15 at intervals.

The turntable 9 rotates through the ball socket 11, ball joint 13, and C-type connecting frame 12, and is converted into left and right reciprocating swing through the rotating shaft 6, thereby driving the conical nozzle 8 to increase the spraying range of the soil remediation agent.

[0034] Subsequently, as the mobile frame 1 moves, the sleeve base 14 rotates, driving the plow blade 19 to till the soil. When it is necessary to adjust the depth of the plow blade 19 into the soil, first loosen the adjusting bolt 21, then adjust the position of the connecting plate 18 on the inclined plane 17. The adjusting bolt 21 can be adjusted within a certain range of distance through the adjusting groove 20. After it is in place, tighten the adjusting bolt 21 again to achieve the effect of adjusting the length of the plow blade 19.
