DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] See also Figures 1 to 7 , a structural diagram of an asphalt production and processing equipment with a heating function provided in Example 1 of the present invention, the asphalt production and processing equipment with a heating function includes: a processing box 10, a crushing assembly 20, a screen plate 30 and a heating mechanism 40. The top of the processing box 10 is provided with a feed inlet 101. The crushing assembly 20 is located in the internal chamber of the processing box 10 and above the screen plate 30. The crushing assembly 20 includes a rotating shaft 201 rotatably arranged at the center of the processing box 10, and a plurality of main crushing members 202 arranged in an array on the outside of the rotating shaft 201. And an outer ring 203 rotatably mounted inside the processing box 10, the outer ring 203 is sleeved on the outside of several main crushing parts 202, and a plurality of vertically extending mounting grooves 204 are arranged in an array on the inner side of the outer ring 203, and a matching crushing part 205 is arranged inside each mounting groove 204. A rotating ring 206 is elastically rotatably sleeved on the outer side of the outer ring 203, and no less than two connecting rods 207 are arranged between the rotating ring 206 and the matching crushing part 205, and the two ends of the connecting rod 207 are rotatably mounted on the matching crushing part 205 and the rotating ring 206 respectively.

[0032] The lower end of the screen plate 30 elastically contacts the support ring 213 , and the crushing assembly 20 further includes a transmission mechanism for driving the screen plate 30 in the lower position to rotate.

[0033] A plurality of drive rods 208 are installed in an array on the sieve plate 30. The drive rods 208 are arranged on the outside of the outer ring 203, and a second protrusion 211 is installed on the side of the drive rod 208 close to the outer ring 203. A transmission rod 209 is installed on the outside of the outer ring 203, and a first protrusion 210 is provided on the outside of the rotating circle 206. The first protrusion 210 is located below the transmission rod 209.

[0034] The heating mechanism 40 is located below the screen plate 30 and is used to heat the raw materials after they are completely crushed.

[0035] The raw materials on the sieve plate 30 are crushed by the main crushing member 202 and the main crushing member 202 impacts and crushes the raw materials on the sieve plate 30. During the crushing process, the raw materials will also impact the matching crushing member 205, which plays an auxiliary crushing role. When the main crushing member 202 cannot be crushed in time, resulting in the accumulation of materials on the sieve plate 30, the sieve plate 30 is lowered. When the sieve plate 30 is lowered to a suitable position, the transmission mechanism drives the sieve plate 30 to rotate. The rotation direction of the sieve plate 30 is opposite to the rotation direction of the crushing assembly 20, so that the raw materials falling on the sieve plate 30 generate a driving force opposite to the main crushing member 202, thereby improving the crushing effect. If the crushing requirement is still not met at this time, the pile of materials on the sieve plate 30 will increase. At this time, the sieve plate 30 will drive the driving rod 208 to continue to descend, and the second protrusion 211 on the driving rod 208 drops to the position aligned with the transmission rod 209 is at the same height. At this time, the side wall of the second protrusion 211 will contact the transmission rod 209, so that the transmission rod 209 drives the outer ring 203 to rotate, and then drives the matching crushing piece 205 to rotate, thereby increasing the collision chance of the raw material and the matching crushing piece 205, further increasing the crushing efficiency. If the crushing requirement cannot be completed at this time, the screen plate 30 will continue to descend, and the second protrusion 211 on the driving rod 208 will continue to descend. At this time, the second protrusion 211 will be at the same height as the first protrusion 210. When the second protrusion 211 rotates and touches the first protrusion 210, the second protrusion 211 will drive the rotating ring 206 to rotate relative to the outer ring 203, and then through the connecting rod 207, the matching crushing piece 205 moves inward, so that the distance between the matching crushing piece 205 and the main crushing piece 202 is reduced, thereby further increasing the crushing opportunity and further completing the crushing requirement. The crushed raw material passes through the screen plate 30 and falls into the heating mechanism 40 for heating and then discharged. The present invention can automatically adjust the crushing efficiency according to the type of raw materials, can effectively meet the crushing needs of different raw materials, provide uniform raw materials for the heating mechanism 40, and ensure the heating effect.

[0036] The outer ring 203 is unidirectionally mounted in the processing box 10, and the direction in which the outer ring 203 can rotate is opposite to the direction in which the rotating shaft 201 rotates. The unidirectional rotation setting ensures that when the outer ring 203 is not rotating, it will not rotate under the action of the main crushing element 202 driving the crushed material, thereby ensuring the crushing effect.

[0037] In some embodiments, the outer ring 203 is rotated and installed inside the processing box 10 through a ratchet structure, thereby achieving the unidirectional rotation of the outer ring 203 in the processing box 10. The ratchet structure is a prior art and will not be described in detail here.

[0038] In some embodiments, the transmission mechanism includes at least two transmission elastic telescopic parts 215 arranged in an array at the bottom of the screen plate 30, and at least two of the transmission elastic telescopic parts 215 are arranged around the outside of the crushing assembly 20. The transmission mechanism also includes a central outer gear ring 219 fixedly sleeved on the outside of the rotating shaft 201, and at least two transmission gears 218 are arranged in an array on the outside of the central outer gear ring 219. The transmission gear 218 is installed on the mounting sleeve 221, and the mounting sleeve 221 is fixedly installed inside the processing box 10. An inner gear ring 217 is rotatably arranged inside the mounting sleeve 221, and several transmission gears 218 are arranged on the inner side of the inner gear ring 217, and the transmission gear 218 is meshed with the inner gear ring 217. The inner side of the transmission gear 218 is meshed with the central outer gear ring 219, and a plurality of mating protrusions 216 are arranged in an array on the upper side of the inner gear ring 217. In this way, when the rotating shaft 201 rotates, it drives the central outer gear ring 219 to rotate, and the central outer gear ring 219 drives the peripheral transmission gear 218 to rotate, and the transmission gear 218 drives the inner gear ring 217 to rotate. When the screen plate 30 descends, it drives the transmission elastic telescopic part 215 to descend, and the transmission elastic telescopic part 215 falls onto the trajectory of the mating protrusion 216. The mating protrusion 216 can drive the screen plate 30 to rotate in the opposite direction relative to the rotating shaft 201 through the mating protrusion 216.

[0039] In some embodiments, the outer side of the support ring 213 is fixedly connected to the inner wall of the processing box 10. The lower end of the support elastic telescopic member 212 abuts against the support ring 213, and the upper end of the support elastic telescopic member 212 is fixedly mounted on the screen plate 30. The support elastic telescopic member 212 is a prior art and will not be described in detail here.

[0040] In some embodiments, a through hole is provided in the middle of the mounting sleeve 221 , and the rotating shaft 201 is provided through the through hole.

[0041] A matching ring 214 is provided at the bottom of the screen plate 30. The matching ring 214 is concentric with the screen plate 30. The matching ring 214 is elastically rotatably mounted on the screen plate 30. The upper end of the transmission elastic telescopic member 215 is fixedly mounted on the matching ring 214, so that when the transmission elastic telescopic member 215 hits the matching protrusion 216, the impact can be slowed down. At the same time, during the crushing process, when the main crushing member 202 approaches the matching crushing member 205, the raw material will squeeze the matching crushing member 205 outward, so that the matching crushing member 205 can move outward, causing the rotating circle 206 to rotate in the opposite direction. The rotating circle 206 drives the second protrusion 211 to drive the screen plate 30 to generate a reverse force, so that the screen plate 30 produces a pause during the rotation process, which can effectively remove the crushed material thereon.

[0042] The matching ring 214 is connected to a plurality of elastic members, and both ends of the elastic members are fixedly mounted on the matching ring 214 and the sieve plate 30 , respectively, so that the matching ring 214 is elastically rotatably mounted on the sieve plate 30 .

[0043] The rotating shaft 201 passes through the center of the sieve plate 30. A crushing motor 220 is fixedly installed inside the processing box 10. The output end of the crushing motor 220 is transmission-connected to the rotating shaft 201, and the crushing motor 220 provides power for the rotating shaft 201 to rotate.

[0044] The heating mechanism 40 includes a stirring mechanism and a heating layer 404 provided on the bottom side wall of the processing box 10 . The heating layer 404 is used to stir the raw materials after the crushing process so that the raw materials can be evenly heated.

[0045] The stirring mechanism includes a stirring shaft 401, a spiral blade 402 and a mixing motor 403 fixedly mounted on the processing box 10. The output end of the mixing motor 403 is transmission-connected to one end of the stirring shaft 401. The stirring shaft 401 is horizontally arranged and rotatably mounted on the processing box 10. The spiral blade 402 is mounted on the stirring shaft 401. When the stirring shaft 401 rotates, the spiral blade 402 is driven to rotate, thereby stirring the crushed raw materials and making the heating more uniform.

[0046] The heating layer 404 includes a protective layer and a heating layer from top to bottom. The protective layer may be made of a metal material for heat transfer, and the heating layer may include a heating resistor.

[0047] The bottom of the processing box 10 is provided with a discharge port 102 for discharging the raw materials after heating.

[0048] like Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the main crushing member 202 includes a mounting sleeve 222 and several groups of crushing units 223 arranged in an array on the outside of the mounting sleeve 222, the crushing units 223 include several crushing teeth vertically installed on the outside of the mounting sleeve 222, and the mounting sleeve 222 is slidably installed on the rotating shaft 201 up and down; a matching ring 301 is fixedly installed on the top of the screen plate 30, and the outer side of the matching ring 301 is rotatably arranged in an annular groove on the inner side wall of the bottom of the mounting sleeve 222, so that the main crushing member 202 can follow the screen plate 30 to descend, ensuring the gap between the main crushing member 202 and the top of the screen plate 30, so that the main crushing member 202 can quickly crush the raw materials.

[0049] A slider 224 is fixedly mounted on the inner side of the mounting sleeve 222. The slider 224 slides up and down in a strip-shaped slot 225 on the side wall of the rotating shaft 201. An elastic member 226 is also provided between the mounting sleeve 222 and the rotating shaft 201. The elastic member 226 can be mounted on the outer side of the rotating shaft 201. The ends of the elastic member 226 are fixedly mounted on the mounting sleeve 222 and the rotating shaft 201, respectively.

[0050] The working principle of the present invention is:

[0051] The raw materials to be crushed are added into the processing box 10 through the feed port 101, and at the same time, the crushing motor 220 drives the rotating shaft 201 to rotate, and the raw materials fall onto the screen plate 30. At this time, the rotating shaft 201 drives the main crushing member 202 to rotate, and the main crushing member 202 impacts and crushes the raw materials on the screen plate 30. During the crushing process, the raw materials will also impact the matching crushing member 205, and the matching crushing member 205 plays an auxiliary crushing role. When the particle size of the raw materials changes, when the main crushing member 202 cannot be crushed in time, resulting in the accumulation of materials on the screen plate 30, the screen plate 30 falls under the action of gravity. When the screen plate 30 drops to the preset position, the transmission elastic telescopic member 215 contacts the matching protrusion 216. At this time, the existence of the central outer gear ring 219, the transmission gear 218 and the inner gear ring 217 makes the screen plate 30 rotate in the opposite direction relative to the rotating shaft 201, so that the raw materials falling on the screen plate 30 generate a driving force opposite to the main crushing member 202, thereby improving the crushing effect. If the crushing requirements are still not met at this time, the pile of materials on the screen plate 30 will increase. At this time, the screen plate 30 will drive the driving rod 208 to continue to drop, and the second protrusion 211 on the driving rod 208 will drop to the position aligned with the transmission rod. 209 is at the same height, at this time the side wall of the second protrusion 211 will conflict with the transmission rod 209, so that the transmission rod 209 drives the outer ring 203 to rotate, and then drives the matching crushing piece 205 to rotate, thereby increasing the collision chance between the raw material and the matching crushing piece 205, further increasing the crushing efficiency. If the crushing cannot be completed at this time, the screen plate 30 will continue to descend, and the second protrusion 211 on the driving rod 208 will continue to descend. At this time, the second protrusion 211 will be at the same height as the first protrusion 210. When the second protrusion 211 rotates, it will touch the first protrusion 210. At this time, the second protrusion 211 will be at the same height as the first protrusion 210. The two protrusions 211 drive the rotating ring 206 to rotate relative to the outer ring 203, and then the matching crushing piece 205 moves inward through the connecting rod 207, so that the distance between the matching crushing piece 205 and the main crushing piece 202 is reduced, thereby further increasing the crushing opportunity and further completing the crushing requirements. The crushed raw materials fall to the bottom of the processing box 10 through the screen plate 30. At this time, the mixing motor 403 drives the spiral blade 402 to rotate through the stirring shaft 401, and the heating layer 404 heats the raw materials. After heating, the raw materials are discharged through the discharge port 102. The present invention can automatically adjust the crushing efficiency according to the type of raw materials, can effectively meet the crushing needs of different raw materials, provide uniform raw materials for the heating mechanism 40, and ensure the heating effect.
