[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0038] In the present invention, when the asphalt material falls onto the screen 5 after being crushed, stirred and ground, the diverter plate 8 automatically separates the asphalt material, so that the asphalt material can be avoided from accumulating when the asphalt material is screened on the screen 5, thereby accelerating the fluidity of the asphalt material on the screen 5 and avoiding material jamming, which helps to speed up the production of the asphalt material and greatly improve the production efficiency of the asphalt material.

[0039] Example 2: Reference Figure 1-Figure 14 , which is basically the same as the first embodiment, and further, the first rotating rod 6 passes through the device housing 1 and is rotatably connected to the device housing 1, the second rotating rod 7 passes through the screen 5 and is rotatably connected to the screen 5, and sliding grooves are provided on the inner walls on both sides of the device housing 1, and the side surface of the screen 5 is fixedly connected with an L-shaped sliding rod 13, and the L-shaped sliding rod 13 is slidably connected to the sliding groove of the device housing 1.

[0040] A first spring 14 is sleeved on the surface of the L-shaped slide bar 13, one end of the first spring 14 is connected to the inner wall of the slide groove of the device housing 1, and the other end of the first spring 14 is fixedly connected to the L-shaped slide bar 13. The second rotating rod 7 passes through the diverter plate 8 and is rotatably and slidably connected to the diverter plate 8. The internal piston of the sealing cylinder 12 is connected to the piston plate 15.

[0041] In the present invention, the screen 5 can slide upward on the slide groove of the device housing 1 under the action of the L-shaped slide rod 13, and at the same time compress the first spring 14. When the screen 5 is reset downward, the elastic force of the first spring 14 can make the screen 5 collide with the bottom of the slide groove of the device housing 1, causing the screen 5 to shake, so that the screen 5 has a better screening effect on the asphalt material.

[0042] A sliding rod 16 is fixedly connected to the top surface of the piston plate 15. The sliding rod 16 passes through the sealing cylinder 12 and is slidably connected to the sealing cylinder 12. A trapezoidal plate 17 is fixedly connected to the top surface of the sliding rod 16. A second spring 18 is sleeved on the surface of the sliding rod 16. One end of the second spring 18 is fixedly connected to the trapezoidal plate 17, and the other end of the second spring 18 is fixedly connected to the sealing cylinder 12.

[0043] In the present invention, the second spring 18 can reset the sliding rod 16 and the trapezoidal plate 17 upward, thereby driving the piston plate 15 to reset upward.

[0044] An air outlet pipe 19 is fixedly connected between the sealing cylinder 12 and the cavity 9 of the diverter plate 8, a through hole is opened between the bottom of the cavity 9 and the brush 10, an air intake pipe 20 is fixedly connected to the left bottom of the sealing cylinder 12, a filter is fixedly installed inside the air intake pipe 20, and a one-way valve is fixedly installed inside the air intake pipe 20 and the air outlet pipe 19, and a discharge plate 21 is fixedly installed on the right surface of the device housing 1.

[0045] In the present invention, while the first motor 101 drives the first rotating rod 6 and the second rotating rod 7 to rotate, the first rotating rod 6 drives the contact plate 11 to contact the inclined surface of the trapezoidal plate 17, and then the sliding rod 16 can only slide up and down in the sealing cylinder 12, so that the trapezoidal plate 17 drives the sliding rod 16 and the piston plate 15 to slide downward, and the compressed air in the sealing cylinder 12 is squeezed out from the air outlet pipe 19, so that the air in the sealing cylinder 12 enters the cavity 9 of the diverter plate 8, and then is ejected from the through hole at the bottom of the cavity 9. Under the reciprocating contact of the contact plate 11 with the trapezoidal plate 17, when the piston plate 15 is reset upward, the sealing cylinder 12 inhales air through the suction pipe 20, thereby The asphalt material in the mesh holes on 5 is blown out, and at the same time, some small lumps of asphalt material can be blown away when the asphalt material is sprayed out, so that the screen 5 can screen the asphalt material faster and the screening effect is more significant; through the one-way valve in the suction pipe 20 and the outlet pipe 19, the gas can be prevented from being squeezed out from the suction pipe 20 when it is squeezed out, and when the gas is inhaled, it can be prevented from being inhaled from the cavity 9 to avoid inhaling asphalt material, which can make the effect of the gas on the sieve holes of the screen 5 more stable; after the screening is completed, the unqualified asphalt material can be poured out from the discharge plate 21 by tilting the entire device for secondary production mixing and grinding.

[0046] A connecting strip 22 is fixedly connected to the lower surface of the second rotating rod 7, a first inclined plate 23 is fixedly connected to the right end surface of the connecting strip 22, a circular groove is provided on the bottom inner wall of the diverter plate 8, a spiral groove is provided on the inner wall of the circular groove of the diverter plate 8, a driving rod 24 passes through the surface of the screen 5, the driving rod 24 is slidably connected to the screen 5, and a circular rod 25 corresponding to the spiral groove on the inner wall of the circular groove of the diverter plate 8 is fixedly connected to the top surface of the driving rod 24.

[0047] An upper top plate 26 is fixedly penetrated through the surface of the driving rod 24 near the bottom of the screen 5, and a second inclined plate 27 is fixedly connected to the bottom surface of the driving rod 24. The second inclined plate 27 is slidably connected to the first inclined plate 23. A third spring 28 is sleeved on the surface of the driving rod 24, and one end of the third spring 28 is fixedly connected to the upper top plate 26, and the other end of the third spring 28 is fixedly connected to the screen 5. A discharge hopper 29 is fixedly connected to the bottom inner wall of the device housing 1.

[0048] In the present invention, while the first motor 101 drives the first rotating rod 6 and the second rotating rod 7 to rotate, the second rotating rod 7 drives the connecting bar 22 and the first inclined plate 23 to rotate. When the first inclined plate 23 rotates to the second inclined plate 27, the two inclined surfaces conflict with each other. The second inclined plate 27 drives the driving rod 24 to slide upward under the action of the driving rod 24 sliding up and down. When the driving rod 24 slides upward, it simultaneously drives the upper top plate 26 to slide upward. When the driving rod 24 slides upward, it first drives the top circular rod 25 to enter the circular groove of the diverter plate 8. The circular rod 25 slides along the inner wall of the spiral groove of the circular groove of the diverter plate 8, and then the diverter plate 8 can be rotated above the screen 5 by an angle. When the circular rod 25 slides to the top of the circular groove of the diverter plate 8 When the screen 5 is moved, the upper top plate 26 presses against the screen 5, and the screen 5 slides upward by compressing the first spring 14 through the L-shaped sliding rod 13. At the same time, the upper top plate 26 compresses the third spring 28. Then, when the first inclined plate 23 is separated from the second inclined plate 27, the third spring 28 drives the upper top plate 26, the driving rod 24 and the second inclined plate 27 to automatically reset downward. The screen 5 automatically resets under the action of the first spring 14, and then the second rotating rod 7 drives the first inclined plate 23 to contact the second inclined plate 27 again, and the reciprocating operation is performed. Therefore, when the screen 5 vibrates up and down for screening, the diverter plate 8 can not only play a diversion effect, but also spray air flow to the sieve holes of the screen 5, and can also rotate to rotate and divert the asphalt material on the surface of the screen 5, so that the asphalt material screening effect is better and the production efficiency is higher.

[0050] In the present invention, when asphalt is initially produced, the second motor 205 is started, and the second motor 205 drives the two rotating shafts 202 to rotate through the second synchronous belt 206 and the first synchronous belt 204, and then drives the two crushing rollers 203 to rotate, and then the asphalt raw material is placed in the box 201 for crushing, and then the raw materials for improving the performance of the asphalt are placed, and the large pieces of asphalt raw materials and other raw materials enter the stirring and mixing component 3, and the first rotating rod 6 drives the stirring rod 301 to rotate. While the stirring rod 301 stirs and mixes the asphalt material, it drives the scraper arm 302 to rotate to scrape the asphalt material on the inner wall of the device housing 1.

[0051] The grinding assembly 4 includes a cylindrical barrel 401, which is fixedly connected to the inner wall of the device housing 1. The bottom surfaces of both sides of the cylindrical barrel 401 are hinged with second baffles 402, and the bottom surface of the second baffle 402 is hinged with a second hydraulic rod 403.

[0052] In the present invention, when the mixing is completed, the first hydraulic rod 304 is started to drive the first baffle 303 to rotate, and then the asphalt material after the mixing falls into the cylindrical barrel 401. Through the smooth arc surface on the first rotating rod 6, the first baffle 303 does not conflict with the first rotating rod 6 when it rotates. Then the first rotating rod 6 drives the two L-shaped connecting rods 405 at the bottom to rotate, and the L-shaped connecting rod 405 drives the first U-shaped frame 406 and the second U-shaped frame 407 to rotate, thereby causing the first grinding roller 408 and the second grinding roller 409 to rotate as a whole. Then, under the meshing action of the gear 411 and the annular rack 412, the first grinding roller 408 and the second grinding roller 409 rotate, and at the same time, the second grinding roller 409 drives The crushing plate 410 on the surface rotates to grind the asphalt material for the second time. When the crushing plate 410 is crushed for the second time, fine asphalt materials will splash outward when crushed. At this time, when the first rotating rod 6 rotates, the circular cloth cover 404 is also driven to rotate. The circular cloth cover 404 will expand outward when rotating to form a shielding circle, which can reduce the asphalt material from splashing upward and damaging the parts inside the device housing 1. When the grinding is completed, the second hydraulic rod 403 is started to drive the second baffle 402 to rotate. Through the smooth arc surface on the second rotating rod 7, the second baffle 402 will not affect the rotation of the second rotating rod 7 when it rotates to unload, and then the ground asphalt material falls onto the screen 5 for screening.

[0054] S1. When in use, the asphalt material is crushed by the crushing component 2, and then falls into the stirring and mixing component 3, and the mixed and ground asphalt raw materials are added, and then stirred and mixed evenly, and then enter the grinding component 4 to grind the asphalt raw materials.
