Description

Technical Field

[0001] This invention relates to the field of contaminated soil remediation technology, and more specifically, to a conveying device with a crushing function for contaminated soil remediation. Background Technology

[0002] Soil remediation refers to the technical measures that use physical, chemical, biological, and ecological principles, along with artificial control measures, to reduce the concentration (activity) of soil pollutants, thereby rendering them harmless and stabilizing them to achieve the desired detoxification effect. Theoretically feasible remediation technologies include several categories such as phytoremediation, microbial remediation, chemical remediation, physical remediation, and integrated remediation. Remediation of contaminated soil is of great significance for preventing pollutants from entering the food chain, preventing harm to human health, and promoting land resource protection and sustainable development.

[0003] According to a patent publication number CN214321281U, published on 2021-10-01, a contaminated soil remediation crushing device includes a crushing vehicle, a connecting plate, and a mounting plate. The connecting plate is fixedly connected to the left side of the crushing vehicle, and the mounting plate is fixedly connected to the middle of the inner side of the connecting plate. This invention overcomes the shortcomings of existing technologies. By incorporating a remediation reagent tank, an inlet pipe, and a sprayer, the device can simultaneously crush contaminated soil and spray the remediation reagent. First, the prepared remediation reagent is loaded into the tank through the inlet pipe at the top. Then, the sprayer extracts the reagent from the tank and sprays it onto the crushed contaminated soil through a nozzle on one side of the spray pipe. This eliminates the need for separate devices to sequentially remediate the contaminated soil, reducing the manpower, resources, and time required for remediation. Although the device includes a stirrer to accelerate the mixing of contaminated soil and remediation reagent, improving efficiency, its crushing mechanism relies on a single crusher. This can lead to incomplete crushing, resulting in larger soil particles that cannot be thoroughly mixed with the remediation reagent. Furthermore, the lack of baffles in the crushing mechanism causes soil to splash onto the ground during crushing, requiring subsequent cleaning and adding unnecessary maintenance.

[0004] Therefore, we urgently need a conveyor device with crushing function for the remediation of contaminated soil. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a conveying device with crushing function for contaminated soil remediation.

[0006] To address the aforementioned technical problems, this invention provides a conveying device with a crushing function for contaminated soil remediation, comprising a base, a cover plate, a conveying assembly, baffles, a chopping mechanism, and a crushing mechanism. The cover plate is mounted on the base, and the conveying assembly is mounted on the base, located inside the cover plate. Baffles are connected to both sides of the conveying assembly; the baffles are inclined plates that will contact the inner wall of the cover plate. The cover plate is equipped with a chopping mechanism, which includes an electric slide rail, a moving plate, a slider, a cutter assembly, and first guide rods. An electric slide rail is mounted on the upper side of the cover plate, and a moving plate is slidably connected to the electric slide rail. A slider is slidably connected to the upper part of the cover plate, and the front part of the moving plate is slidably connected to the slider. A cutter assembly is connected to the bottom of the slider. Two first guide rods are symmetrically slidably connected to the upper part of the cover plate. Each of the two rear first guide rods has at least six grooves, and the bottom of each first guide rod is connected to the cutter assembly. The crushing mechanism is located at the rear of the cover plate.

[0007] Preferably, the crushing mechanism includes a crushing frame and a crushing roller assembly, with the crushing frame installed at the rear of the cover plate, and the crushing roller assembly rotatably connected inside the crushing frame.

[0008] Preferably, the crushing mechanism further includes an inclined plate rotatably mounted on the rear side of the crushing frame for feeding.

[0009] Preferably, it further includes a pressing mechanism. The pressing mechanism is provided on the crushing frame. The pressing mechanism includes a second guide rod, a first rotating plate, a second rotating plate, a pressing plate, and a sliding plate. The front part of the crushing frame is connected to the second guide rod. The first rotating plate is slidably connected to the second guide rod. The lower end of the first rotating plate is rotatably connected to the moving plate. The upper end of the first rotating plate is rotatably connected to the second rotating plate. Sliding plates are symmetrically slidably connected inside the crushing frame. The pressing plate is connected to the pressing plate. The pressing plate is slidably connected to the crushing frame. The other end of the second rotating plate is rotatably connected to the upper side of the pressing plate.

[0010] Preferably, the bottom surface of the lower pressure plate is convex in the middle and concave on the left and right sides, and conforms to the curved surface of the crushing roller assembly.

[0011] Preferably, it also includes a vibration mechanism. The vibration mechanism is provided on the transmission assembly. The vibration mechanism includes an elastic element, a connecting rod and a protrusion. An elastic element is connected between the transmission assembly and the base. A connecting rod is connected to the rear of the transmission assembly. A protrusion is symmetrically connected to the upper front side of the connecting rod. The protrusion fits into a groove close to itself.

[0012] Preferably, it also includes a repair agent spraying mechanism. The repair agent spraying mechanism is provided on the cover plate. The repair agent spraying mechanism includes a liquid storage tank and a nozzle. Liquid storage tanks are symmetrically installed inside the cover plate. Each liquid storage tank is equipped with a nozzle, and the nozzles all penetrate the baffle.

[0013] Preferably, at least six nozzles are installed on the liquid storage tank.

[0014] This invention, by installing a baffle, allows the cutting assembly to contact the contaminated soil as the slider moves downwards. As it continues to move downwards, it further shreds the contaminated soil. During the shredding process, soil particles may splash out, contacting the baffle and falling back onto the conveyor belt. This prevents soil particles from splashing onto the ground, eliminating the need for the operator to clean the ground after the work is completed. Thus, this device simplifies the workflow.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1: A conveying device with crushing function for contaminated soil remediation, such as... Figures 1-5As shown, the system includes a base 1, a cover plate 101, a conveying assembly 102, a baffle 103, a shredding mechanism 2, and a crushing mechanism 3. The cover plate 101 is bolted to the left and right sides of the base 1. The cover plate 101 is semi-circular. The conveying assembly 102 is located inside the cover plate 101. Baffles 103 are bolted to both sides of the conveying assembly 102. The baffles 103 are inclined plates that will contact the inner wall of the cover plate 101. The shredding mechanism 2 is mounted on the cover plate 101. The shredding mechanism 2 includes an electric slide rail 21, a moving plate 22, a slider 23, a cutter assembly 24, and a first guide rod 25. An electric slide rail 21 is bolted to the upper side of the cover plate 101. A movable plate 22 is slidably connected to the electric slide rail 21. A slider 23 is slidably connected to the upper part of the cover plate 101. The front part of the movable plate 22 is slidably connected to the slider 23. A cutter assembly 24 is fixed to the bottom of the slider 23. The cutter assembly 24 is composed of multiple cutters. Two first guide rods 25 are symmetrically slidably connected to the upper part of the cover plate 101. At least six grooves 251 are opened on the two rear first guide rods 25. The bottom of the first guide rods 25 are connected to the cutter assembly 24. A crushing mechanism 3 is provided at the rear of the cover plate 101.

[0025] When using this device, first pour the contaminated soil into the crushing frame 31 through the inclined plate 32, then drive the power source of the crushing roller assembly 33. The crushing roller assembly 33 starts to rotate, crushing the contaminated soil. The crushed soil falls onto the conveying assembly 102 through the gaps between the crushing roller assemblies 33. The conveying assembly 102 transports the contaminated soil forward while simultaneously driving the electric push rod. The electric push rod moves the moving plate 22 backward. As the moving plate 22 moves backward, its front part slides backward on the slider 23. At the same time, the slider 23 moves downward, taking the cutter assembly 24 with it. The cutter assembly 24 moves downward, taking the first guide rod 25 with it. The cutter assembly 24 and the contaminated soil... After contact with the soil, as it continues to move downwards, the contaminated soil will be shredded again. Soil particles splashed out during the shredding process by the cutter assembly 24 will come into contact with the baffle 103 and fall back onto the conveyor belt, preventing soil particles from splashing onto the ground. This eliminates the need for the operator to clean up the ground after the work is completed, thus simplifying the workflow. When the front of the moving plate 22 can no longer move backwards on the slider 23, the blades of the cutter assembly 24 come into contact with the conveyor assembly 102. The electric push rod then resets the moving plate 22, which in turn resets the slider 23. Simultaneously, the slider 23 resets, along with the cutter assembly 24 and the first guide rod 25. The above steps are repeated to shred the contaminated soil multiple times, thus enabling the device to thoroughly break down the contaminated soil.

[0026] Example 2: Based on Example 1, such as Figure 1 and Figures 3-5 As shown, the crushing mechanism 3 includes a crushing frame 31, an inclined plate 32, a crushing roller assembly 33, and a pressing mechanism 4. The crushing frame 31 is bolted to the rear of the cover plate 101, and the crushing roller assembly 33 is rotatably connected to the inside of the crushing frame 31 via a rotating shaft. The inclined plate 32, used for feeding, is rotatably mounted on the rear side of the crushing frame 31. The pressing mechanism 4 is provided on the crushing frame 31, and the pressing mechanism 4 includes a second guide rod 41, a first rotating plate 42, a second rotating plate 43, a pressing plate 44, and a sliding plate 45. The front of the crushing frame 31 is connected to the second guide rod 41. A first rotating plate 42 is slidably connected to the rod 41. The lower end of the first rotating plate 42 is rotatably connected to the moving plate 22 via a rotating shaft. The upper end of the first rotating plate 42 is rotatably connected to the second rotating plate 43 via a rotating shaft. Slide plates 45 are symmetrically slidably connected inside the crushing frame 31. A lower pressure plate 44 is connected between the slide plates 45. The bottom surface of the lower pressure plate 44 is convex in the middle and concave on the left and right sides, and conforms to the curved surface of the crushing roller assembly. The lower pressure plate 44 is slidably connected to the crushing frame 31. The other end of the second rotating plate 43 is rotatably connected to the upper side of the lower pressure plate 44 via a rotating shaft.

[0027] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a vibration mechanism 5 and a repair agent spraying mechanism 6. The vibration mechanism 5 is provided on the conveying assembly 102. The vibration mechanism 5 includes an elastic element 51, a connecting rod 52 and a protrusion 53. The elastic element 51 is connected to the conveying assembly 102 and the base 1 through a spring seat. The connecting rod 52 is fixedly connected to the rear of the conveying assembly 102. The upper front side of the connecting rod 52 is symmetrically connected to the protrusion 53. The protrusion 53 fits into the groove 251 close to itself. The repair agent spraying mechanism 6 is provided on the cover plate 101. The repair agent spraying mechanism 6 includes a liquid storage tank 61 and a nozzle 62. The liquid storage tank 61 is symmetrically installed on the left and right sides of the cover plate 101 by bolts. At least six nozzles 62 are installed on each liquid storage tank 61, and the nozzles 62 all penetrate the baffle 103.

[0028] As the moving plate 22 moves backward, the first rotating plate 42 moves backward on the second guide rod 41. The first rotating plate 42 moves backward, carrying the second rotating plate 43 with it. Simultaneously, the second rotating plate 43 applies force to the downward pressing plate 44, causing it to press down. The downward pressing plate 44 moves downward within the crushing frame 31 via the sliding plate 45. When encountering large contaminated soil lumps, the crushing roller assembly 33 cannot crush them, and these lumps will remain on the assembly. If left untreated, this could clog the crusher, preventing further crushing operations. When the downward pressing plate 44 contacts the large contaminated soil lumps on the crushing roller assembly 33, it presses them down, ensuring close contact with the assembly. This allows the crushing roller assembly 33 to break the larger contaminated soil lumps, improving the crushing efficiency of the device and preventing blockage of the crushing mechanism 3. In this process, as the first guide rod 25 moves down or up, the protrusion 53 continuously disconnects from the groove 251 and engages with other grooves 251, then disconnects again. This causes the connecting rod 52 to continuously move the conveying assembly 102 back and forth in sync. When the protrusion 53 disconnects from the groove 251, the elastic element 51 is compressed; when the protrusion 53 engages with the groove 251, the elastic element 51 rebounds and resets. This allows the conveying assembly 102 of this device to slightly shake the contaminated soil while transporting it, thereby improving the shredding efficiency and the mixing efficiency of the contaminated soil and the remediation agent. The nozzle 62 sprays the remediation agent from the storage tank 61 onto the contaminated soil, allowing it to mix thoroughly. Once the remediation agent has fully reacted with the contaminated soil, the soil remediation work is completed. Subsequent work can be done by repeating the above steps. After the work is completed, the device is turned off.

It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
