[0005] Therefore, it is necessary to provide a new production device for coal-based solid waste artificial soil to solve the above technical problems. Summary of the Utility Model

In order to improve the cleanliness of the entire working environment, workers need to frequently clean the coal-based solid waste that has fallen to the ground. The sliding of the coal-based solid waste from the production device will also cause the entire production device to have poor stability in transporting the coal-based solid waste, affecting the working process of producing coal-based solid waste artificial soil through the production device.

[0007] To solve the above technical problems, the present utility model provides a production device for coal-based solid waste artificial soil, including: a production device body, four support legs are fixedly connected to the lower surface of the production device body, an adjusting device is provided on one side of the production device body, the adjusting device includes a fixed rod, the fixed rod is fixedly connected to one of the support legs, a support plate is fixedly connected to the end of the fixed rod away from the support leg, a motor is fixedly connected to one side of the support plate, a bidirectional screw rod is fixedly connected to the output end of the motor, two connecting blocks are threadedly connected to the arc surface of the bidirectional screw rod, a limiting frame is fixedly connected to the side of the connecting block close to the production device body, one of the limiting frames is slidably connected to the inner wall of the other limiting frame, auxiliary grooves are formed in the bottom wall of the limiting frame, and a plurality of the auxiliary grooves are evenly distributed on the bottom wall of the limiting frame, and a guiding plate is fixedly connected to one side of the limiting frame.

[0008] The effects achieved by the above components are as follows: Coal gangue and fly ash are coal-based solid wastes generated during coal production, processing, and power generation. Coal-based solid wastes are one of the industrial solid wastes with the largest emissions and cumulative stockpiles in China. The current main treatment method for coal-based solid wastes is landfill in stockyards. A large amount of stacking will occupy a large area of land. Coal-based solid wastes are alkaline and contain heavy metal elements, causing serious water and soil pollution after long-term stacking. Some coal gangue will spontaneously combust, causing air pollution. At the same time, coal-based solid wastes are also a resource that can be developed and utilized. The state encourages the large-scale utilization and high-value utilization of coal-based solid wastes, including using coal-based solid wastes for land reclamation, saline-alkali land treatment, and ecological environment restoration of gangue mountains.

In order to meet the market demand for the technology of artificial soil made of coal-based solid wastes, the production device of artificial soil made of coal-based solid wastes mainly consists of a conveying device, a mixing and stirring device, a soil activation system, and a packaging machine. The special production device for artificial soil made of coal-based solid wastes can be used to improve the production efficiency of artificial soil made of coal-based solid wastes. However, during the process of transporting coal-based solid wastes into the mixing and stirring device through the production device, it is found that when the coal-based solid wastes are transported on the production device body, during the movement of the coal-based solid wastes, the coal-based solid wastes that pile up too high will fall from the production device body to the ground, resulting in pollution of the ground by the coal-based solid wastes. In order to improve the cleanliness of the entire working environment, workers need to frequently clean the coal-based solid wastes that have fallen to the ground. The coal-based solid wastes slide out of the production device body, resulting in poor stability of the entire production device body for transporting coal-based solid wastes. At this time, the transportation angle of the coal-based solid wastes on the production device body can be adjusted through an adjusting device, so as to avoid the coal-based solid wastes from falling out of the production device body by adjusting the transportation angle of the coal-based solid wastes.

A guiding plate 207 is fixedly connected to one side of the limiting frame 206. Coal gangue and fly ash are coal-based solid wastes generated during coal production, processing and power generation. Coal-based solid wastes are one of the industrial solid wastes with the largest emissions and cumulative stockpiles in China. The current main treatment method of coal-based solid wastes is landfill in stockyards. A large amount of stacking will occupy a large area of land. Coal-based solid wastes are alkaline and contain heavy metal elements, which will cause serious water and soil pollution after long-term stacking. Some coal gangue will catch fire spontaneously, causing air pollution. At the same time, coal-based solid wastes are also a kind of resource that can be developed and utilized. The state encourages the large-scale utilization and high-value utilization of coal-based solid wastes, including the use of coal-based solid wastes for land reclamation, saline-alkali land treatment and ecological environment restoration of coal gangue mountains. It is found that adding artificial soil of coal-based solid wastes for planting in desertified soil lacking nutrients has good effects, low price and simple operation. In order to meet the market demand for the technology of artificial soil of coal-based solid wastes, the production device of artificial soil of coal-based solid wastes mainly consists of a conveying device, a mixing and stirring device, a soil activation system and a packaging machine. The special production device of artificial soil of coal-based solid wastes can be used to improve the production efficiency of artificial soil of coal-based solid wastes. However, it is found that during the process of transporting coal-based solid wastes into the mixing and stirring device through the production device, when the coal-based solid wastes are transported on the production device body 1, during the movement of the coal-based solid wastes, the coal-based solid wastes piled up too high will fall from the production device body 1 to the ground, resulting in pollution of the ground by the coal-based solid wastes. In order to improve the cleanliness of the whole working environment, workers need to frequently clean the coal-based solid wastes that have fallen to the ground. The coal-based solid wastes slide out from the production device body 1, resulting in poor stability of the whole production device body 1 in transporting the coal-based solid wastes. At this time, the adjusting device 2 can be used to adjust the transportation angle of the coal-based solid wastes on the production device body 1, so as to avoid the coal-based solid wastes falling out of the production device body 1 by adjusting the transportation angle of the coal-based solid wastes. A connecting ring 209 is fixedly connected to the side of the limiting frame 206 away from the guiding plate 207.

When the motor 203 drives the two limiting frames 206 to move, the connecting rings 209 installed on the limiting frames 206 will slide on the limiting rod 210.Thus, it can slide on the limiting rod 210 through the connecting ring 209 to improve the stability of the movement of the two limiting frames 206. The arc surface of the motor 203 is slidably connected with a protective shell 211. Threaded rods 212 penetrate through both ends of the arc surface of the protective shell 211. The threaded rods 212 are threadedly connected with the inner wall of the support plate 202. The surface of the motor 203 is relatively fragile. The protective shell 211 can be installed on the surface of the motor 203 through the threaded rods 212. Thus, the motor 203 can be protected by the protective shell 211, and the motor 203 can be prevented from malfunctioning when being bumped. A plurality of heat dissipation holes 213 are formed in the arc surface of the protective shell 211. The plurality of heat dissipation holes 213 are evenly distributed on the arc surface of the protective shell 211. When the motor 203 is protected by the protective shell 211, the heat dissipation holes 213 formed in the protective shell 211 can discharge the heat energy generated by the movement of the motor 203, so as to prevent the heat energy from affecting the service life of the motor 203. The fixing rod 201 is a titanium alloy rod. The rod body of the fixing rod 201 made of titanium alloy material is relatively hard, which also makes it difficult for the fixing rod 201 to deform after long-term use, and the service life is good;

[0034] In an embodiment of the present invention, please refer to Figure 4 and Figure 5 ., the auxiliary device 3 includes a bottom plate 301. The bottom plate 301 is fixedly connected with two of the support legs 4. An electric push rod 302 is fixedly connected to the side of the bottom plate 301 away from the production device body 1. Two sliding rods 303 penetrate through the inner wall of the bottom plate 301 in a sliding manner. A clamping block 304 is slidably connected to the inner wall of the sliding rod 303. The same storage box 305 is fixedly connected to the sides of the two clamping blocks 304 away from the sliding rod 303. A cleaning plate 306 is fixedly connected to the side of the storage box 305 close to the production device body 1. A convex block 310 is fixedly connected to one side of one of the sliding rods 303. A plug rod 307 penetrates through the inner wall of the convex block 310 in a sliding manner. The plug rod 307 penetrates through the clamping block 304 and the sliding rod 303 in a sliding manner. A spring 308 is sleeved on the arc surface of the plug rod 307. The two ends of the spring 308 are respectively fixedly connected to the convex block 310 and the plug rod 307. After the production device body 1 transports the coal-based solid waste, the production device body 1 can be cleaned by the auxiliary device 3. Thus, the production device body 1 can be cleaned in time by the auxiliary device 3 to prevent impurities of the coal-based solid waste from depositing on the production device body 1 and affecting the subsequent transportation effect of the coal-based solid waste by the production device body 1. A pull ring 309 is rotatably connected to the inner wall of the plug rod 307. When it is necessary to pull the plug rod 307, the plug rod 307 can be pulled through the pull ring 309 installed on the plug rod 307. Thus, the speed of pulling the plug rod 307 can be increased through the pull ring 309;

[0035] The working principle of a production device for coal-based solid waste artificial soil provided by the present utility model is as follows: When it is necessary to limit the conveying angle of the coal-based solid waste, the motor 203 installed on the support plate 202 is started. The movement of the motor 203 will drive the bidirectional screw 204 to rotate through the output end. The rotation of the bidirectional screw 204 will drive two limit frames 206 to move through the connecting block 205, so that the guide plate 207 can be driven to move through the movement of the two limit frames 206. The angle between the two guide plates 207 is the angle size when transporting the coal-based solid waste. The auxiliary grooves 208 opened on the limit frames 206 can prevent the coal-based solid waste from accumulating inside the limit frames 206.

[0036] When it is necessary to clean the production device body 1, pull the insertion rod 307 to the side away from the sliding rod 303, and the clamping block 304 installed on the storage box 305 can be connected to the inner wall of the sliding rod 303. At this time, release the insertion rod 307, and the spring 308 will drive the insertion rod 307 to be connected to the sliding rod 303 through the clamping block 304. At this time, the electric push rod 302 installed on the bottom plate 301 can be started. The movement of the electric push rod 302 will contact the bottom of the storage box 305 through the output end, so that the sliding rod 303 can be driven to slide in the bottom plate 301 by pushing the storage box 305, and the cleaning plate 306 installed on the storage box 305 can be contacted with the production device body 1, so that the production device body 1 can be cleaned by the cleaning plate 306.
