[0002] Asphalt concrete, also known as asphalt concrete, is a mixture made by artificially selecting mineral aggregates, crushed stone or crushed gravel, stone chips or sand, mineral powder, etc. with a certain gradation and mixing them with a certain proportion of road asphalt materials under strict control conditions. Asphalt concrete can be divided into two main categories according to the different binders used: petroleum asphalt and coal tar pitch.

[0003] In existing recycled asphalt concrete production, the raw materials are fed into a container and then processed through mixing and heating to achieve the desired shape before being discharged. However, in the existing technology, the discharge process usually requires pouring and expanding the opening for direct processing. Direct discharge results in rapid unloading, which can easily damage the equipment structure due to stress changes. Furthermore, slow discharge can easily cause blockages that are difficult to clean.

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1-4 As shown, this embodiment proposes a mixing and heating device for recycled asphalt concrete, including a heating support assembly 1 and a discharge component 4.

The output end of the hydraulic valve chamber 401 is provided with a transverse pipe 402, and one end of the transverse pipe 402 is provided with a second housing 403 connected to the output end of the second motor 404. The output end of the second housing 403 is provided with a spline slot 405, and one end of the spline slot 405 is provided with a transverse auger 406. One end of the transverse auger 406 is provided with an end shaft insert 407.

[0022] The transverse auger 406 and the end shaft insert 407 are connected by a movable bearing.

[0023] In this embodiment, after the material processing is completed, the hydraulic valve chamber 401 is used to output the material into the horizontal pipe 402, and the second motor 404 is used to output power to drive the output end to run. After the second motor 404 outputs the power, it drives the second housing 403 to output the material. This causes the spline slot 405 to drive the horizontal auger 406 to output the material to the equipment.

[0024] The heating mounting assembly 1 includes a base plate 101, an assembly base plate 102, an end bracket 103, a support shell 104, an outer side plate 105, and a heating rod 106. The assembly base plate 102 is disposed above the center of the base plate 101, and the end bracket 103 is disposed above the side of the assembly base plate 102. The support shell 104, on which the outer side plate 105 is mounted, is disposed above the end bracket 103, and the heating rod 106 is disposed on the inner side of the support shell 104.

[0025] In this embodiment, heating rods 106 arranged in a ring array inside the bearing shell 104 on the end frame 103 can be used to heat the bearing compartment 201, so that the outer side plate 105 can achieve the effect of heat insulation.

[0026] The feeding assembly 2 includes a bearing chamber 201, a bottom arc seat 202, a top cover 203, a feed port 204, a liquid inlet valve block 205, and a pneumatic cover plate 206. The bearing chamber 201 is bolted to the inner side of the bearing shell 104. The bottom arc seat 202 is provided on the lower inner side of the bearing chamber 201. The top cover 203 is bolted on the top of the bearing chamber 201. The feed port 204 is provided on one end of the top cover 203. The liquid inlet valve block 205 is provided on one side above the feed port 204. The pneumatic cover plate 206 is provided on the top of the feed port 204.

[0027] In this embodiment, during use, sufficient material is input into the bearing chamber 201 through the inlet 204 above one end of the top cover 203. Then, the inlet 204 is closed after being output by the pneumatic cover plate 206. Sufficient liquid raw materials can be injected into the equipment using the liquid inlet valve block 205.

[0028] The mixing mechanism 3 includes a bolt end frame 301, a crossbeam 302, a first housing 303, and a first motor 304. The bolt end frame 301 is bolted to the upper ends of the base plate 101. A crossbeam 302 is provided above the bolt end frame 301, and a first housing 303 connected to the output end of the first motor 304 is provided above the middle part of the crossbeam 302.

[0029] In this embodiment, the first motor 304 can be used to output power to drive the output end to run, so that after the first motor 304 outputs power, it drives the first chassis 303 to output power.

[0030] The mixing mechanism 3 also includes an output shaft 305, a rotating frame 306, an inner stirring rod 307, and an end auger 308. The output end of the first housing 303 is provided with an output shaft 305, and the output end of the output shaft 305 is provided with a rotating frame 306. The inner stirring rod 307 is provided on the outer side of the middle part of the rotating frame 306, and the end augers 308 are provided on the outer sides of both ends of the rotating frame 306.

[0031] In this embodiment, after the first chassis 303 is in operation, it drives the output shaft 305 to operate. The output operation of the output shaft 305 can drive the rotating frame 306 to rotate. The rotation of the rotating frame 306, together with the inner stirring rod 307 and the end auger 308, effectively and fully stirs the material during the heating process.

[0032] The working principle of the recycled asphalt concrete mixing and heating device is as follows: During use, sufficient material is fed into the bearing chamber 201 through the inlet 204 above one end of the top cover 203. Then, the inlet 204 is closed after being opened by the pneumatic cover plate 206. Sufficient liquid raw materials can be injected into the equipment using the liquid inlet valve block 205. The bearing chamber 201 is heated using the annular array of heating rods 106 arranged inside the bearing shell 104 on the end frame 103, which also provides heat insulation to the outer side plate 105. The first motor 304 outputs power to drive the output end, causing the first motor 304 to drive the first housing 303 to output power. When the first housing 303 starts operating, it drives the output shaft 305 to operate. The output shaft 305 drives the rotating frame 306 to rotate. The rotation of the rotating frame 306, together with the inner stirring rod 307 and the end auger 308, effectively and thoroughly stirs the material during the heating process. After the material is processed, the hydraulic valve chamber 401 is used to output the material into the transverse pipe 402. The second motor 404 then outputs power to drive the output end, which in turn drives the second housing 403 to operate. This causes the spline slot 405 to drive the transverse auger 406 to output the material from the equipment.
