[0002] Concrete is a composite material mixed with water, aggregates (such as sand, gravel or broken bricks, etc.), cement and other materials added as needed (such as admixtures, additives, etc.). It is one of the widely used structural materials in modern construction and is highly favored for its high strength, good durability, low cost and easy construction.

[0003] In order to ensure the connection strength of concrete, concrete raw materials such as crushed stone or broken bricks need to be crushed before processing and mixing. For example, the patent application number published on the China Patent Network is: 202011087593.1, and the patent name is: A crushing device for concrete production, including: a frame for support and installation; a lifting rod, which can be lifted and installed on the frame; a crushing hammer, which is installed at the bottom of the lifting rod and is used for crushing raw materials; a hopper, which is installed on the frame and is used to hold raw materials; a crushing trough, which is installed on the frame below the hopper and has a discharge hole at the bottom, and a crushing space is formed inside; an S-shaped top rod, which is rotatably set on the frame and cooperates with the support seat installed on the lifting rod to drive the lifting rod to lift upward; a driving member, which is installed on the frame and is used to drive the S-shaped top rod to rotate; wherein the lifting rod passes through the hopper and the crushing hammer is below the hopper, the crushing hammer is raised to block the hopper, and the crushing hammer descends to crush the raw materials inside the crushing trough. Advantages of the present invention: simple structure, convenient operation, good crushing effect, energy saving, and good synchronization.

[0004] However, the crushing device mainly discharges the crushed materials by direct discharge.

[0043] refer to Figure 4 The inclined structure 5 includes a vertical plate 11 fixedly connected to the front and rear sides of the top of the base 1, and the vertical plates 11 are respectively located on the front and back of the crushing body 2. The front and back of the crushing body 2 are fixedly connected with a shaft rod 12, and the outer end of the shaft rod 12 passes through the vertical plate 11 and extends to the outside of the vertical plate 11.

The electric telescopic rod 13 is driven by a controller, and the swing angle of the electric telescopic rod 13 is pre-set to prevent the electric telescopic rod 13 from causing the internal crushing machine body 2 to be thrown out during the short-range movement.

[0046] As a technical optimization scheme of the present invention, the connecting plate 14 is driven to move back and forth in a short distance by the electric telescopic rod 13. During the movement of the connecting plate 14, the bracket 15 is used to drive the slide bar 17 to slide inside the sleeve plate 16. The sleeve plate 16 is squeezed by the slide bar 17 and uses the shaft rod 12 to drive the crushing machine body 2 to swing around the shaft rod 12 as the axis, which can accelerate the crushing effect and drive the screen plate 9 to move back and forth. Moreover, when the electric telescopic rod 13 drives the connecting plate 14 to move to the maximum stroke, the crushing machine body 2 connected to the sleeve plate 16 can be synchronously swung and tilted, so that the crushed materials inside the crushing machine body 2 can be dumped out through the discharge frame 3, thereby achieving the effect of controlling the discharge state.

[0047] refer to Figure 5 The linkage structure 7 includes an extension plate 18 fixedly connected to the outside of the connection block 10, and the side of the extension plate 18 away from the connection block 10 extends to the outside of the vertical plate 11. The side of the extension plate 18 away from the connection block 10 is fixedly connected to a toothed plate 19 located on the outside of the vertical plate 11. The outer end of the shaft 12 passes through the outside of the sleeve plate 16 and is fixedly connected to a gear 20. The gear 20 is located at the top of the toothed plate 19. The toothed plate 19 and the gear 20 are meshed with each other. When the gear 20 rotates, the toothed plate 19 can be used to drive the sieve plate 9 connected to the extension plate 18 to move horizontally. When working, the gear 20 connected to the crushing machine body 2 through the shaft 12 can rotate synchronously. The gear 20 uses its teeth to push the tooth plate 19 to move to the left. The tooth plate 19 uses the extension plate 18 to transmit power and drives the screen plate 9 to move synchronously to the side close to the crushing machine body 2 through the connecting block 10. The number of meshing teeth between the tooth plate 19 and the gear 20 is set according to the moving distance of the screen plate 9. At the same time, the tooth plate 19 and the extension plate 18 are fixedly connected by a threaded assembly, so that the meshing distance between the tooth plate 19 and the gear 20 can be adjusted.

[0049] refer to Figure 6 A pushing frame 21 is provided inside the sieve plate 9, and sliders 22 are fixedly connected to both sides of the inner wall of the sieve plate 9. The opposite sides of the two sliders 22 extend to the inside of the pushing frame 21. The sliders 22 are slidably connected to the pushing frame 21, and the pushing frame 21 can evenly spread the crushed materials on the surface of the sieve plate 9.

[0050] As a technical optimization solution of the present invention, by providing a pushing frame 21, the crushed materials can be evenly distributed during the reciprocating movement of the screen plate 9, thereby improving the crushed material distribution effect.

[0051] refer to Figure 6 A movable block 23 is fixedly connected to the right side of the frame 8, and a rocker arm 24 is movably connected to the inner side of the movable block 23 through a pin shaft. A transmission rod 25 located inside the rocker arm 24 is fixedly connected to the outer side of the sieve plate 9, and a linkage rod 26 is fixedly connected to the top of the pushing frame 21. The linkage rod 26 extends from the side away from the pushing frame 21 to the inner side of the rocker arm 24, and a support rod 27 located inside the rocker arm 24 is fixedly connected to the outer side of the linkage rod 26. Both the support rod 27 and the transmission rod 25 are slidably connected to the rocker arm 24. The length of the rocker arm 24 is proportional to the moving distance of the sieve plate 9. When the sieve plate 9 moves to the bottom of the discharge frame 3, the pushing frame 21 located at the top of the sieve plate 9 should be pushed to the right side of the sieve plate 9.

[0052] As a technical optimization scheme of the present invention, during the reciprocating movement of the screen, the screen drives the transmission rod 25 to slide inside the rocker arm 24, the rocker arm 24 is squeezed and swings with the pin shaft on the surface of the movable block 23 as the axis, and during the swinging process of the rocker arm 24, the support rod 27 is used to squeeze the linkage rod 26 connected to it, and the linkage rod 26 drives the push frame 21 to move in the opposite direction on the surface of the screen plate 9, and evenly spreads the raw materials on the surface of the screen plate 9 and improves the contact uniformity between the crushed materials and the screen plate 9.

[0053] refer to Figure 4 The bottom of the extension plate 18 is fixedly connected with an angle plate 28, and the surface of the angle plate 28 is set to be hollow.

[0054] As a technical optimization solution of the present invention, by providing the angle plate 28, the structural strength of the extension plate 18 can be improved, thereby preventing the extension plate 18 from bending and deforming due to excessive load-bearing.

[0055] The working principle and use process of the present invention are as follows: when in use, the crushing machine body 2 is used to crush the crushed materials. During the processing, the electric telescopic rod 13 drives the connecting plate 14 to move back and forth in a short distance. During the movement of the connecting plate 14, the bracket 15 drives the sliding rod 17 to slide inside the sleeve plate 16. The sleeve plate 16 is squeezed by the sliding rod 17 and uses the shaft rod 12 to drive the crushing machine body 2 to swing around the shaft rod 12 as the axis. The discharging frame 3 obliquely arranged on the surface of the crushing machine body 2 can block the crushed materials inside the crushing machine body 2 to prevent the crushed materials from being thrown out during the swinging process. When the crushed materials inside the crushing machine body 2 are processed to the required time, the electric telescopic rod 13 drives the connecting plate 14 When the pulverizer body 2 is moved to the maximum stroke, the pulverizer body 2 connected to the sleeve plate 16 is synchronously swung and tilted, so that the crushed materials inside the pulverizer body 2 can be dumped out through the discharge frame 3. During the swinging process of the pulverizer body 2, the gear 20 connected to the pulverizer body 2 through the shaft 12 can rotate synchronously. The gear 20 uses the teeth to push the tooth plate 19 to move to the left. The tooth plate 19 uses the extension plate 18 to transmit power and drives the screen plate 9 to move synchronously to the side close to the pulverizer body 2 through the connecting block 10. When the screen plate 9 moves to the bottom of the discharge frame 3 on the surface of the pulverizer body 2, the raw materials inside the discharge frame 3 can be directly dumped into the screen plate 9. When the crushed materials on the surface of the screen plate 9 reach a certain number, the pulverizer body 2 is moved to the bottom of the discharge frame 3 on the surface of the pulverizer body 2. When measuring, the electric telescopic rod 13 is started to reset and the above-mentioned short-range swing operation is cyclically performed. During the short-range swinging process of the crushing machine body 2, the gear 20 can use the tooth plate 19 to pull the screen plate 9 to swing back and forth. During the reciprocating swinging process of the screen plate 9, the contact area between the surface screen and the crushed materials is accelerated and the centrifugal force during the movement is used to accelerate the screening of the crushed materials, so that the qualified crushed materials are filtered through the screen and fall to the bottom of the screen for collection. During the reciprocating movement of the screen, the screen can drive the transmission rod 25 to slide inside the swing rod 24, and the swing rod 24 is squeezed and swings with the pin shaft on the surface of the movable block 23 as the axis. During the swinging process of the swing rod 24, the support rod 27 is used to squeeze and The linkage rod 26 connected to it drives the push frame 21 to move in the opposite direction on the surface of the screen plate 9 and evenly spreads the raw materials on the surface of the screen plate 9 and improves the uniformity of contact between the crushed materials and the screen plate 9. In the process of the above-mentioned screen plate 9 moving to the bottom of the discharge frame 3 to receive the material, the screen plate 9 uses the transmission rod 25 to pull the rocker arm 24 to swing to the left, and the rocker arm 24 uses the support rod 27 to pull the push frame 21 to the right side of the screen plate 9 through the linkage rod 26. When the push frame 21 continues to move, it can push the unqualified crushed materials that cannot be screened on the top of the screen plate 9 to the right side of the screen plate 9, so that they fall to the outside of the screen plate 9, thereby avoiding the operation of the screen plate 9 being affected.

[0056] To sum up: the raw material crushing device for concrete production with automatic material sorting can screen the crushed materials by setting the sorting structure 4, and can effectively control the particle size of the crushed materials. At the same time, the crushing body 2 connected by the tilting structure 5 can control the discharge time and state, and the crushing body 2 during the tilting process can accelerate the contact uniformity between the crushed materials and the internal crushing components, thereby improving the crushing effect. At the same time, the crushing body 2 can pull the sorting structure 4 to oscillate back and forth during the swinging process, thereby further improving the contact uniformity and screening effect between the sorting structure 4 and the crushed materials.
