[0068] Please refer to Figures 1-11 , the present invention provides a solid waste classification and collection and reuse device based on asphalt concrete. This device can be used for solid waste classification and collection treatment of asphalt concrete. At the same time, this device changes the treatment method of asphalt concrete, reduces the damage to stones during the treatment of asphalt concrete, and thus ensures the strength of the stones.

[0069] Including:

[0070] A machine body 1, on the upper part of which a feeding port 2 is provided and a hoisting device for asphalt pavement placement is configured, and a discharge port 3 is provided on the side of the machine body 1;

[0071] A crushing device 21, located within the feeding port 2, in which a crushing wheel 213 capable of placing multiple asphalt pavements is provided, and crushing teeth 215 for supporting the crushing position of the asphalt pavement are configured inside the placement groove 214. A clamping assembly 23 for clamping the asphalt pavement is provided inside the crushing device 21, and the clamping assembly 23 cooperates with the crushing teeth 215 to form the clamping of the asphalt pavement;

[0072] A commutation structure 22, located inside the crushing device 21 and connected to the crushing device 21, which forms the support for the bottom of the asphalt pavement and realizes driving the asphalt pavement to rotate;

[0073] The heat treatment tank 24 is arranged below the crushing device 21 and is used for heat-treating the crushed asphalt pavement to separate the asphalt. A drying chamber 25 is arranged on its side. The discharge of the heat treatment tank 24 extends into the interior of the drying chamber 25, and the transportation of the heat-treated pavement material between the two is realized through a conveying device.

[0074] The classification component 26 is located at the discharge position of the drying chamber 25 and realizes the classification of stones and fillers.

[0075] In this embodiment, the setting of the crushing device 21 can change the crushing method of the traditional crushing device 21 for the asphalt pavement, so as to ensure that the impact on the stones during crushing can be reduced during use, and further ensure the stability of the pavement crushing during use. Instead of the traditional impact extrusion force, the pavement is split open, which can ensure the position of the pavement crushing and ensure the uniformity of the size of the pavement after crushing.

[0076] In one embodiment, the crushing device 21 further includes:

[0077] The driving motor 211 is located outside the machine body 1 and fixedly connected to the machine body 1. A transmission gear 212 is fixedly sleeved outside the output end of the driving motor 211. The crushing wheel 213 extends from the inside of the machine body 1 to the outside of the machine body 1 and is connected to drive the transmission gear 212, and the crushing wheel 213 moves synchronously with the transmission gear 212.

[0078] The placement groove 214 is opened on the inner side of the crushing wheel 213 and is used for placing the asphalt pavement. The opening of the placement groove 214 faces upward. The crushing teeth 215 are fixedly connected to the inner wall of the placement groove 214, and a support block 216 is further arranged on one side of the crushing teeth 215, and the support block 216 is fixedly connected to the inner wall of the placement groove 214.

[0079] In this embodiment, the setting of the placement groove 214 cooperates with the clamping component 23 to complete the clamping of the asphalt pavement, so that the asphalt pavement can be stably clamped during use. When the driving motor 211 rotates, it will drive the transmission gear 212 to rotate. The transmission gears 212 are meshed with each other, and the transmission gear 212 is connected to the crushing wheel 213. Therefore, the two crushing wheels 213 rotate in opposite directions to realize the crushing of the pavement.

[0080] Among them, when the two crushing wheels 213 swing in an arc and the middle position is upward, it is the crushing state of the pavement. When the two crushing wheels swing in an arc and the middle position is downward, it is the blanking state, so that the crushed pavement can enter the interior of the heat treatment tank 24.

[0081] In one embodiment, the commutation structure 22 includes:

[0082] The placement plate 221 is detachably arranged inside the placement groove 214. The placement plates 221 are magnetically connected by magnetic blocks 222. The placement plates 221 form a ring shape. The crushing teeth 215 and the support blocks 216 are both located inside the placement plates 221.

[0083] The chute 224 is annularly arranged inside the placement groove 214. A connecting head 225 extending to the inside of the chute 224 is arranged at the lower part of the placement plate 221. The connecting head 225 is fixedly connected to the placement plate 221, and the placement plate 221 is limited by the connecting head 225 and the chute 224.

[0084] In this embodiment, the placement plates 221 are composed of multiple mutually magnetically attracted parts. After the multiple placement plates 221 are combined, a complete ring shape is formed. The bottom of the asphalt pavement contacts the inner side surface of the placement plates 221. After the placement plates 221 are rotated, the asphalt pavement inside can be driven to rotate at the same angle. Moreover, the inner side surface of the placement plates 221 is slightly higher than the crushing teeth 215 and the support blocks 216, and will not be affected by the crushing teeth 215 and the support blocks 216 during the rotation process.

[0085] In one embodiment, the reversing structure 22 further includes:

[0086] The reversing motor 226 is fixed inside the crushing wheel 213. A ratchet gear is fixedly sleeved on the output end of the reversing motor 226. Meshing teeth 223 extending to the inside of the crushing wheel 213 are formed on the outside of the placement plate 221. The meshing teeth 223 are in meshing transmission with the ratchet gear.

[0087] Among them, the edge of the placement plate 221 is arc-shaped.

[0088] In this embodiment, the arrangement of the reversing motor 226 can automatically drive the placement plate 221 to rotate, so as to change the angular position of the asphalt pavement, thereby ensuring the angle adjustment of the asphalt pavement during use. The arrangement of the meshing teeth 223 and the ratchet gear can ensure the accuracy of the adjustment of the placement plate 221 during rotation.

[0089] Among them, setting the edge position of the placement plate 221 as arc-shaped can make the force application point on the road surface be on the crushing teeth 215 when breaking the asphalt pavement, avoiding damage to the edge of the placement plate 221.

[0090] In one embodiment, the clamping assembly 23 includes:

[0091] The ejector rod 231 extends from inside the crushing wheel 213 to inside the placement groove 214. The ejector rod 231 is telescopic. A positioning head 232 is arranged at one end of the ejector rod 231 extending into the crushing wheel 213. The positioning head 232 is fixedly connected to the ejector rod 231.

[0092] The hydraulic pump 234 is fixed to the outside of the machine body 1. The liquid outlet of the hydraulic pump 234 is provided with a hydraulic pipe 235 extending into the machine body 1. The hydraulic pipe 235 is flexibly arranged, and one end facing away from the hydraulic pump 234 extends into the driving wheel. Inside the crushing wheel 213, there is a hydraulic chamber which is communicated with the hydraulic pump 234, and the ejector rod 231 is inserted into the hydraulic chamber.

[0093] The pressing plate 237 is inserted into the hydraulic chamber from inside the placement groove 214.

[0094] In this embodiment, through the operation of the hydraulic pump 234, hydraulic oil can be pushed into the hydraulic chamber through the hydraulic pipe 235. The hydraulic oil is used to push the ejector rod 231 and the pressing plate 237 to extend outwards, forming a clamping and fixing of the asphalt pavement, restricting the position of the asphalt pavement, and ensuring the stability of the asphalt pavement.

[0095] Among them, the ejector rods 231 are symmetrically arranged. The synchronous outward movement of the two ejector rods 231 can push the hydraulic road surface towards the middle of the placement groove 214, so that the asphalt road can be in the middle position of the placement groove 214.

[0096] In one embodiment, the clamping assembly 23 further includes:

[0097] The slot 236 is opened on the inner side of the placement plate 221. The ejector rod 231 can pass through the slot 236 and extend into the placement groove 214.

[0098] The limiting protrusion 233 is located at one end of the positioning head 232 facing away from the ejector rod 231. The end position of the limiting protrusion 233 is conical and is used to contact the fracture edge position of the asphalt pavement.

[0099] The clamping block 238 is fixed to the lower part of the pressing plate 237 and is used to contact the upper surface of the asphalt pavement.

[0100] Among them, the pressing plate 237 is inclined and installed inside the crushing wheel 213.

[0101] In this embodiment, the position of the clamping block 238 is outside the breaking position of the asphalt pavement. The crushing teeth 215 are located on the lower surface of the asphalt pavement and close to the breaking position of the asphalt pavement, while the clamping block 238 is located on the upper surface of the asphalt pavement and outside the crushing teeth 215. By using the settings of the crushing teeth 215 and the clamping block 238, clamping of the upper and lower positions of the asphalt pavement can be formed, ensuring the stability of the asphalt pavement during the crushing process.

[0102] Among them, the pressing plate 237 is set to be inclined and extended. During the process of the pressing plate 237 extending towards the breaking position of the road surface, the gap between the clamping block 238 and the upper surface of the road surface can be gradually reduced until clamping of the road surface is formed.

[0103] In one embodiment, the classification component 26 includes:

[0107] In this embodiment, the recovery plate 262 does not have mesh holes. When in use, the processed stones and fillers are filtered through the screen 261. The complete stones will roll down the screen 261 and flow out of the body 1, while the incomplete stones and other fillers will be guided by the recovery plate 262 into the rolling screen 263. The rolling screen 263 rotates to allow the crushed stones and fillers to enter the mesh plate 264, and fall into the recovery trough 266 according to the different gears of the mesh plate 264.

[0108] In one embodiment, a baffle 267 and a partition 265 are provided inside the rolling screen 263 . The partitions 265 are evenly spaced inside the rolling screen 263 . The baffle 267 forms a seal for the end of the rolling screen 263 facing away from the rolling motor.

[0109] In this embodiment, the partition 265 is provided to lift the gravel, so that the gravel can roll inside the rolling screen 263, thereby facilitating the classification of gravel larger than the filler.

[0110] An embodiment of the present invention further provides an operating method for a solid waste classification, collection and reuse device, which is used for the above-mentioned solid waste classification, collection and reuse device based on asphalt concrete, comprising the following steps:

[0111] S1, after crushing the road surface, transport it to the hot regeneration plant, and use the lifting equipment to put the asphalt road surface from the feeding port 2 into the crushing device 21;

[0112] S2: The clamping assembly 23 is activated, pushing the asphalt pavement toward the middle of the crushing device 21 and clamping the sides and top of the pavement. After the clamping is stable, the crushing device 21 swings and breaks the asphalt pavement from the middle.

[0113] S3, after breaking, the clamping assembly 23 and the crushing device 21 are reset, and the reversing structure 22 is activated, rotating a certain angle according to the size of the asphalt pavement, the clamping assembly 23 clamps the asphalt pavement again, and the crushing device 21 crushes the asphalt pavement again;

[0114] S4: The crushed road surface falls into the heat treatment tank 24, decomposes into gravel and filler after heat treatment, and is transported to the drying chamber 25 for drying;

[0115] S5. The dried stones and fillers are classified by the classification component 26.

[0116] In one embodiment, the classification component 26 classifies the stones into recyclable stones and crushed stones. The recyclable stones are directly transported out of the machine body 1, and the crushed stones and fillers are classified and recycled.

[0117] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

[0118] 1. When processing an asphalt pavement, the present invention can first crush the asphalt pavement so that the pavement can be stably heat-treated inside the heat treatment tank 24. During the crushing process, the asphalt pavement can be broken outward from the middle position to achieve crushing, which can reduce the impact on the pavement during crushing, thereby ensuring the strength of the gravel.

[0119] 2. When the present invention crushes the road surface, the road surface can be crushed at different angles by rotating the road surface angle position, so that the road surface can be broken at different positions, and different amounts of crushing can be performed according to the size of the road surface, so that different road surfaces can be selectively crushed when being processed.

[0120] 3. The present invention can ensure the stability of the road surface during the crushing process by clamping the road surface. The shape of the road surface during crushing is not fixed. Road crushing structures of different shapes are generated according to the position where the road surface is excavated. After the road surface is stably clamped and fixed, the stability of the road surface during crushing can be ensured, avoiding the problem of unstable crushing due to the distorted shape of the road surface.

[0121] 4. After the road surface is heat-treated, the asphalt in the road surface is removed, and the gravel and other fillers inside are dried and then classified. At the same time, the gravel crushed materials and other fillers can be classified and processed, so that the gravel crushed materials and other fillers can be reused for other purposes.

[0122] Although the present invention is disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the attached claims.
