[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4The utility model provides a technical solution: a device for crushing and screening waste asphalt pavement milling materials, comprising a body 1, a moving mechanism 2 is arranged inside the body 1, a feed port 3 is arranged on the top surface of the body 1, an annular plate 4 is arranged on the outer side of the bottom end of the body 1, and the cross-sectional shape of the annular plate 4 is a "mouth" shape, the annular plate 4 is in contact with the body 1, and discharge ports 5 are arranged on both side surfaces of the body 1.

[0023] The motion mechanism 2 includes a crushing wheel 201, and there are two crushing wheels 201. A rotating motor 202 is arranged on the front of one end of each crushing wheel 201. The output shaft end of the rotating motor 202 is transmission-connected to the crushing wheel 201. A supporting plate 203 is arranged at the bottom of the rotating motor 202. A horizontal threaded rod 204 is arranged at one end of the supporting plate 203. A gear 205 is arranged on the outer side of one end of the horizontal threaded rod 204, and the gear 205 is threadedly connected to the horizontal threaded rod 204. A lifting rod 206 is arranged on the back of the gear 205. There are two lifting rods 206. The bottom ends of the two lifting rods 206 are fixedly connected to the annular plate 4. Vertical threaded rods 207 are arranged on both sides of the top of the body 1, and the vertical threaded rods 207 are threadedly connected to the lifting rods 206. A pushing rod 208 is arranged inside the bottom end of the body 1. A sieve plate 209 is arranged on the top of the pushing rod 208, and sieve holes 210 are arranged on the surface of the sieve plate 209.

[0024] A gear track is disposed on the front of the top end of the lifting rod 206 , and the gear track is meshed with the gear 205 . A first motor 211 is disposed on the top end of the vertical threaded rod 207 .

[0025] The output shaft end of the first motor 211 is transmission-connected to the vertical threaded rod 207 , and a slide groove 212 is provided on the front side of the machine body 1 .

[0026] The sieve holes 210 are matched with the push rods 208 . There are multiple sieve holes 210 and multiple push rods 208 . Each sieve hole 210 and each push rod 208 are vertically arranged in a collinear manner.

[0027] A sealing plate 213 is provided inside the discharge port 5, and the sealing plate 213 is fixedly connected to the body 1 by screws. A cross plate 214 is provided inside the bottom end of the body 1, and extension rods 215 are provided at both ends of the cross plate 214. The push rod 208 passes through the cross plate 214 and contacts with the cross plate 214.

[0028] During operation, a rotating motor 202 is used to drive the crushing wheel 201 to rotate, so that the two crushing wheels 201 rotate at the same time, and the material enters the interior of the machine body 1 through the feed port 3. The material is crushed by the rotation of the two crushing wheels 201, and the crushed material falls on the screen plate 209, and the material continues to move downward through the screen hole 210 to screen the material. After that, the screws at the sealing plate 213 are removed, the sealing plate 213 is removed, and the discharge port 5 is opened, so that the material on the horizontal plate 214 can be collected through the discharge port 5. After that, the first motor 211 is used. Since the output shaft end of the first motor 211 rotates with the vertical threaded rod 207, the vertical threaded rod 207 is driven to rotate by the first motor 211. When the vertical threaded rod 207 rotates, the lifting rod 206 threadedly connected with the vertical threaded rod 207 moves upward. The lifting rod 206 is fixedly connected to the annular plate 4, so that the annular plate 4 moves upward with the lifting rod 206. When the annular plate 4 moves upward, since the annular plate 4 is fixedly connected to the pushing rod 208, multiple pushing rods 208 move upward at the same time. Because the pushing rod 208 penetrates the horizontal plate 214, the lifting rod 206 is fixedly connected to the annular plate 4. And it contacts with the cross plate 214, so that the push rod 208 is exposed, and the bottom end of the push rod 208 contacts with the cross plate 214, and the push rod 208 continues to move upward, so that the cross plate 214 moves upward at the same time. When the push rod 208 moves upward, the distance between the push rod 208 and the sieve hole 210 can be reduced, and then the push rod 208 can be allowed to enter the sieve hole 210, so that the cross plate 214 contacts with the sieve plate 209, and the impurities in the sieve hole 210 are pushed, and the impurities remaining in the sieve hole 210 are pushed to the top, and the sieve plate 209 can be cleaned through the discharge port 5. When the lifting rod 206 moves upward, the rack moves upward at the same time, and the rack meshes with the gear 205, causing the gear 205 to rotate. When the gear 205 rotates, the threaded rod 207 is threadedly connected to the gear 205, so that the threaded rod 207 moves, and drives the support plate 203 to move, so that the rotating motor 202 and the crushing wheel 201 above move along the slide groove 212, and the distance between the two crushing wheels 201 is enlarged, allowing impurities to fall downward, thereby cleaning the crushing wheel 201 and the screen plate 209 at the same time, improving work efficiency and facilitating subsequent use.
