[0014] As a preferred technical solution of this utility model, a water-blocking plug is installed on the drain outlet for storing a large amount of water to deeply soak and clean the sorted construction waste. The water-blocking plug is made of rubber. A groove is provided at the end of the discharge hopper away from the shell, and a discharge plate for storing water and discharging material is inserted into the groove.

[0015] As a preferred technical solution of this utility model, a guide block is fixedly installed on the side of the second conveyor belt near the inclined vibrating screen, and the guide block is made of carbon steel.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By setting up a sorting component, the inclined vibrating screen sorts the sand and gravel contained in the dumped construction waste. The first servo motor is started, driving the eccentric wheel to rotate. The rotation of the eccentric wheel simultaneously strikes the inclined vibrating screen and the first inclined guide plate. The protrusion of the eccentric wheel strikes the bottom of the inclined vibrating screen, causing it to vibrate. When the eccentric wheel strikes the inclined vibrating screen, the gravel slides down to the second inclined guide plate and is discharged, while the sand falls into the second inclined guide plate due to the vibration of the inclined vibrating screen. On the first inclined guide plate, when the eccentric wheel hits the first inclined guide plate, the first inclined guide plate is pressed down quickly by the elastic force of the spring. When the eccentric wheel moves away from the first inclined guide plate, the two springs rebound upward, causing the first inclined guide plate to vibrate and quickly return to its original position, which will accelerate the sliding speed of the sand. By rotating the support column, the first conveyor belt is opened vertically with the first inclined guide plate. The sand on the first inclined guide plate slides down quickly from high to low onto the first conveyor belt and is discharged, thereby sorting the stones and sand in the construction waste.

[0018] 2. By setting up a cleaning component, during use, the stones discharged from the second inclined guide plate will fall into the inclined drain screen. Opening the valve of the external water pipe will cause multiple nozzles to spray water downwards, cleaning the stones. Starting the vibration motor will drive the inclined drain screen to vibrate. The vibration of the inclined drain screen and the downward spraying of water from the multiple nozzles can deeply clean the stones. Then, the stones will slide from high to low from the inclined drain screen into the discharge hopper for discharge. The water used to clean the stones will be filtered through the inclined drain screen into the drain tank. Finally, the water in the drain tank will be discharged from the drain outlet, which enables deep cleaning of the sorted stones, facilitating subsequent recycling and reuse.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] like Figure 1 As shown, this embodiment proposes an environmentally friendly construction waste resource sorting machine, including a frame 1, a sorting component 2 for sorting construction waste is provided on the top of the frame 1, and a cleaning component 3 for cleaning the sorted construction waste is provided on one side of the frame 1.

[0032] like Figure 3 and Figure 6As shown, the sorting assembly 2 includes an inclined vibrating screen 201 hinged to the inner top of the frame 1. A baffle 202 is fixedly installed on one side of the inner side of the frame 1. A first servo motor 203 is fixedly installed on one side of the frame 1. An eccentric wheel 204 is fixedly installed at the output end of the first servo motor 203. The eccentric wheel 204 is located inside the frame 1 and works in conjunction with the inclined vibrating screen 201. A first inclined guide plate 205 is hinged to the inner side of the frame 1. A placement plate 206 is fixedly installed inside the frame 1. Two springs are installed on the top of the placement plate 206. Springs 207, two springs 207, are fixedly connected at the ends away from the placement plate 206 to the bottom of the first inclined guide plate 205. A support column 208 is installed inside the frame 1, and a first conveyor belt 209 is installed on the top of the support column 208. A second inclined guide plate 210 is installed on the inner top of the frame 1. Four support legs 211 are fixedly installed at the bottom of the frame 1. During use, the inclined vibrating screen 201 sorts the sand and gravel contained in the poured construction waste. The first servo motor 203 is started, driving the rotation of the eccentric wheel 204. The rotation of eccentric wheel 204 simultaneously strikes the inclined vibrating screen 201 and the first inclined guide plate 205. The protrusion of the eccentric wheel 204 strikes the bottom of the inclined vibrating screen 201, causing it to vibrate. When the eccentric wheel 204 strikes the inclined vibrating screen 201, stones slide down to the second inclined guide plate 210 due to the vibration of the inclined vibrating screen 201 and are discharged. Sand falls onto the first inclined guide plate 205 due to the vibration of the inclined vibrating screen 201. When the eccentric wheel 204 strikes the first inclined guide plate 205, the first inclined guide plate... The material plate 205 is pressed down quickly with the help of the spring 207. When the eccentric wheel 204 moves away from the first inclined guide plate 205, the two springs 207 rebound upward, causing the first inclined guide plate 205 to vibrate and quickly return to its original position, which will accelerate the sliding speed of the sand. The support column 208 rotates to make the first conveyor belt 209 open vertically with the first inclined guide plate 205. The sand on the first inclined guide plate 205 slides down quickly from high to low onto the first conveyor belt 209 and is discharged, thereby sorting the stones and sand in the construction waste.

[0033] like Figure 5 and Figure 7As shown, the cleaning assembly 3 includes a housing 301 movably mounted on one side of the frame 1. Multiple nozzles 302 are fixedly mounted on the top of the housing 301 and are connected to an external water supply pipe. An inclined drain screen 303 is fixedly mounted inside the housing 301. A drain groove 304 is formed at the bottom inner side of the housing 301. A drain outlet 305 is formed on one side of the housing 301. A vibration motor 306 is fixedly mounted at the bottom of the housing 301. A discharge hopper 307 is formed on one side of the housing 301. Two support frames 308 are fixedly mounted at the bottom of the housing 301. During use, stones discharged from the second inclined guide plate 210 fall onto the inclined drain screen 303. Opening the valve of the external water pipe causes multiple nozzles 302 to spray water downwards, cleaning the stones. The vibration motor 306 is then activated, causing the inclined drain screen 303 to vibrate. The combined vibration of the inclined drain screen 303 and the downward spraying of water from the multiple nozzles 302 deeply clean the stones. The stones then slide from high to low off the inclined drain screen 303 into the discharge hopper 307 for discharge. The water used to clean the stones is filtered through the inclined drain screen 303 into the drain trough 304. Finally, the water in the drain trough 304 is discharged from the drain outlet 305, enabling deep cleaning of the sorted stones and facilitating subsequent recycling and reuse.

[0034] like Figure 3 As shown, a second conveyor belt 4 for convenient multi-angle feeding is hinged to one side of the frame 1. An extension block 5 is fixedly installed on the side of the frame 1 near the second conveyor belt 4. A hydraulic rod 6 is hinged to one side of the extension block 5. The end of the hydraulic rod 6 away from the extension block 5 is hinged to the bottom of the second conveyor belt 4. Protective plates 7 for preventing material leakage are fixedly installed on both sides of the top of the second conveyor belt 4. The protective plates 7 are made of carbon steel. In use, the second conveyor belt 4 can easily and evenly feed materials. Then, the hydraulic rod 6 is activated to change the tilt angle of the second conveyor belt 4 to facilitate feeding materials at different angles. The protective plates 7 on the second conveyor belt 4 can effectively prevent material leakage during feeding.

[0035] like Figure 3 As shown, a first bevel gear 8 is fixedly installed on the bottom of the support column 208. A second servo motor 9 is installed inside the frame 1. A second bevel gear 10 is fixedly installed on the output end of the second servo motor 9. The second bevel gear 10 meshes with the first bevel gear 8. The bottom of the support column 208 is rotatably connected to the inner bottom of the frame 1. When in use, the second servo motor 9 is started, and the second bevel gear 10 and the first bevel gear 8 cooperate to drive the rotation of the support column 208, thereby causing the first conveyor belt 209 and the first inclined guide plate 205 to open vertically, and the sand is discharged from the first conveyor belt 209.

[0036] like Figure 3 and Figure 5As shown, a bracket 11 is fixedly installed on the top of the frame 1. A laser sensor 12 is installed on the bracket 11 near the bottom of the vibrating screen. An alarm 13 is installed on the top of the bracket 11. The alarm 13 is used in conjunction with the laser sensor 12. When in use, the laser sensor 12 can monitor the material height on the inclined vibrating screen 201. When the material exceeds the set height, the alarm 13 will be triggered to prevent material overflow during feeding.

[0037] like Figure 5 and Figure 7 As shown, a water-blocking plug 14 is installed on the drain outlet 305 for storing a large amount of water to deeply soak and clean the sorted construction waste. The water-blocking plug 14 is made of rubber. A groove 15 is opened at the end of the discharge hopper 307 away from the shell 301. A discharge plate 16 for storing water and discharging material is inserted into the groove 15. When in use, the water filtered by the inclined drain screen 303 will flow into the drain trough 304. At this time, the water-blocking plug 14 is used to block the drain outlet 305 and the discharge plate 16 is inserted into the discharge hopper 307 to prevent water from flowing out. When the water overflows the stones, it can deeply soak and clean the stones.

[0038] like Figure 3 As shown, a guide block 17 is fixedly installed on the side of the second conveyor belt 4 near the inclined vibrating screen 201. The guide block 17 is made of carbon steel. When in use, the guide block 17 can guide the construction waste and prevent the construction waste from falling into the gap between the first conveyor belt 209 and the frame 1.

[0039] Specifically, in use, this environmentally friendly construction waste sorting machine works as follows: The inclined vibrating screen 201 sorts the sand and gravel contained in the poured construction waste. The first servo motor 203 is started, driving the eccentric wheel 204 to rotate. The rotation of the eccentric wheel 204 simultaneously strikes the inclined vibrating screen 201 and the first inclined guide plate 205. The protrusions of the eccentric wheel 204 strike the bottom of the inclined vibrating screen 201, causing it to vibrate. When the eccentric wheel 204 strikes the inclined vibrating screen 201, the gravel... The sand slides down the inclined vibrating screen 201 and onto the second inclined guide plate 210 for discharge. The sand also falls onto the first inclined guide plate 205 due to the vibration of the inclined vibrating screen 201. When the eccentric wheel 204 strikes the first inclined guide plate 205, the first inclined guide plate 205 is quickly pressed downwards by the elastic force of the spring 207. When the eccentric wheel 204 moves away from the first inclined guide plate 205, the two springs 207 rebound upwards, causing the first inclined guide plate 205 to vibrate and quickly return to its original position, thus accelerating. The sliding speed of the sand, through the rotation of the support column 208, causes the first conveyor belt 209 to open perpendicularly to the first inclined guide plate 205. The sand on the first inclined guide plate 205 slides rapidly from high to low onto the first conveyor belt 209, thus discharging the sand and separating the gravel and sand in the construction waste. The gravel discharged from the second inclined guide plate 210 falls onto the inclined drain screen 303. The valve of the external water pipe is opened, causing multiple nozzles 302 to spray water downwards, washing the gravel. The vibration motor 30 is then started. 6. The vibrating motor 306 drives the inclined drain screen 303 to vibrate. The vibration of the inclined drain screen 303 and the downward spraying of water from multiple nozzles 302 work together to deeply clean the stones. The stones then slide from high to low on the inclined drain screen 303 into the discharge hopper 307 for discharge. The water used to clean the stones is filtered through the inclined drain screen 303 into the drain trough 304. Finally, the water in the drain trough 304 is discharged from the drain outlet 305, enabling deep cleaning of the sorted stones and facilitating subsequent recycling and reuse. All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
