[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Example 1: As Figures 1 to 6 As shown in the figure, an embodiment of the present invention provides a waste aerated concrete block recycling and crushing device, comprising a body 1, a movable jaw plate, and a fixed jaw plate. Both the movable and fixed jaw plates include a connecting plate 2 and a crushing hood 3 slidably connected thereto. A dust extraction chamber 4 is formed between the connecting plate 2 and the crushing hood 3 for dust extraction. A dustproof ring 13 is installed on the outer side of the connecting plate 2 away from the body 1 for sealing. An elastic separating element is provided between the connecting plate 2 and the crushing hood 3. Air extraction holes 30 are evenly distributed on the opposite sides of the two crushing hoods 3. A crushing head 5 adapted to the air extraction port 30 is provided. The movable jaw plate is driven by the eccentric shaft of the machine body 1 to reciprocate towards the fixed jaw plate, so that the air block between the movable jaw plate and the fixed jaw plate is crushed. The dust suction chamber 4 reciprocates to extract and collect the dust generated by crushing. At the same time, the sealing part of the crushing head 5 is quickly inserted into the air extraction port 30 to seal it. Meanwhile, the crushing part of the crushing head 5 gradually extends out of the crushing cover 3 to crush the crushed air block again, thereby improving the crushing efficiency of the original jaw crusher.

[0021] like Figure 3 and Figure 4As mentioned above, after a period of implementation, the elasticity of the elastic separator decreases, which can easily cause the separation distance between the connecting plate 2 and the crushing cover 3 to shorten, making it impossible for the crushing head 5 to disengage from the air extraction hole 30, thus preventing the dust extraction chamber 4 from sucking up dust. To solve the above problem, the elastic separator is designed with uniformly opened installation through holes 31 on the crushing cover 3. A compression spring 8 is installed in the installation through hole 31. On the side of the compression spring 8 away from the connecting plate 2, there is a pressure adjusting sleeve 9 that is threadedly connected to the installation through hole 31. The inner hole of the pressure adjusting sleeve 9 is stepped. A limiting screw 10 that is fixedly connected to the connecting plate 2 is inserted into the pressure adjusting sleeve 9. A protective cap 12 is provided at the outer end of the installation through hole 31. The limiting screw 10 is adjusted according to the actual condition of the compression spring 8 so that the distance between the connecting plate 2 and the pressure adjusting sleeve 9 is kept constant. The expansion and contraction stroke of the dust extraction chamber 4 formed between the connecting plate 2 and the crushing cover 3 is controlled by controlling the pressure adjusting sleeve 9.

[0022] like Figure 3 , Figure 4 and Figure 6 As shown, during the implementation process, it was found that the vibration during crushing was relatively large, which caused the pressure regulating sleeve 9 to easily shift. This resulted in differences in the deformation and compression of the compression spring 8, thereby disrupting the parallel sliding between the connecting plate 2 and the crushing cover 3. This increased the frictional loss of the contact surface between the two, which in turn affected the sealing performance of the dust collection chamber 4. Therefore, a locking sleeve 11 that is threadedly connected to the mounting through hole 31 is installed on the outside of the pressure regulating sleeve 9. The locking sleeve 11 has a deformation groove at one end near the pressure regulating sleeve 9, and the end of the pressure regulating sleeve 9 near the locking sleeve 11 is provided with an arc-shaped protrusion. When the pressure regulating sleeve 9 moves outward and compresses the locking sleeve 11 during vibration, the end of the locking sleeve 11 with the deformation groove deforms and expands outward, thereby making the locking sleeve 11 fit tightly against the inner wall of the mounting through hole 31, thus locking and fixing the pressure regulating sleeve 9.

[0023] The lower side of the crushing hood 3 is provided with a one-way exhaust assembly 6. The outlet end of the one-way exhaust assembly 6 is connected to a dust filter bag 7. The one-way exhaust assembly 6 includes an air guide hood 60. The lower side of the crushing hood 3 has an exhaust port 32 that communicates with the dust suction chamber 4. The lower side of the crushing hood 3 is provided with an air guide hood 60 that is adapted to the exhaust port 32. One side of the air guide hood 60 is provided with an air supply pipe 61 that is connected to the dust filter bag 7. The air supply pipe 61 is provided with a one-way exhaust component. The one-way exhaust component can be a one-way valve, so that the dust gas can only flow out in one direction along the air supply pipe 61 and the dust in the dust gas discharged through the one-way valve is filtered out by the dust filter bag 7.

[0024] like Figures 3 to 5 As shown, a rubber buffer pad 13 is provided at the end of the connecting plate 2 away from the machine body 1. The outer contour dimension of the rubber buffer pad 13 is designed to be larger than the cross-sectional dimension of the dust suction chamber 4, which realizes the seal between the connecting plate 2 and the crushing cover 3, avoids rigid impact when the connecting plate 2 and the crushing cover 3 are closed, and eliminates the noise generated by the crushing of the compressed air block.

[0025] like Figure 3 and Figure 5 As shown, the crushing head 5 consists of a cylindrical blocking section and a conical crushing section. When the volume of the dust collection chamber 4 is at its maximum, the distance from the end of the blocking section of the crushing head 5 to the air extraction hole 30 is 1.5-3 mm. At the same time, the length of the crushing section of the crushing head 5 is designed to penetrate through the air extraction hole 30, so that when the dust collection chamber 4 contracts, the blocking section can be instantly inserted into the air extraction hole 30, thus sealing the air extraction hole 30 and preventing the dust and gas sucked into the dust collection chamber 4 from leaking out of the air extraction hole 30. At the same time, by having the crushing section penetrate through the air extraction hole 30, the crushing and squeezing effect of the crushing head 5 is increased, while preventing larger crushed particles from entering the dust collection chamber 4 through the air extraction hole 30. Furthermore, when the crushing head 5 moves outward from the air extraction hole 30, the external contour characteristics of the conical crushing section facilitate the ejection of debris stuck in the air extraction hole 30 during dust collection, thereby reducing the frictional loss between the blocking section and the inner wall of the air extraction hole 30.

[0026] like Figure 1 and Figure 3 As shown, the crushing end of the crushing hood 3 is toothed with interlocking concave and convex sections, and several air extraction holes 30 are evenly arranged in the concave part of the crushing end to prevent the crushed aerated blocks from being squeezed into the air extraction holes 30 during the crushing process.

[0027] Example 2: Figure 1 , Figure 3 and Figure 7 As shown in Example 1, another embodiment of the present invention is described below: During implementation, since the gas transported through the gas pipe 61 contains a large amount of dust, the one-way valve is prone to failure after a period of use. To avoid the above situation, the one-way exhaust component is installed in a stepped mounting cylinder 62 on one side of the machine body 1, and the gas pipe 61 is connected to the mounting cylinder 62. A sealing flap 64 is rotatably installed inside the mounting cylinder 62. A torsion spring 63 is installed on the rotating part of the sealing flap 64. The sealing flap 64 is driven to flip in one direction by the elastic force of the torsion spring 63 to avoid the phenomenon of gas backflow.

[0028] Working Principle: During operation, the eccentric shaft of the machine body 1 drives the movable jaw plate to reciprocate towards the fixed jaw plate, causing the aerated block between the movable and fixed jaw plates to be crushed. At the initial stage of crushing, the connecting plate 2 and the connected crushing hood 3 close, causing the elastic separating element to be gradually compressed and deformed. Simultaneously, the sealing part of the crushing head 5 quickly inserts into the air extraction hole 30 to seal it. At the same time, the crushing part of the crushing head 5 gradually extends out of the crushing hood 3 to further crush the crushed aerated block, improving the crushing efficiency of the original jaw crusher. Simultaneously, the dust collection chamber 4 gradually contracts, causing the gas stored in the dust collection chamber 4 to be squeezed out through the exhaust port 32, ultimately allowing the gas to pass through... After passing through the air guide hood 60 and the air supply pipe 61, all the air enters the dust bag 7 through the one-way exhaust component. Then, the movable jaw plate moves in the opposite direction away from the fixed jaw plate. At the same time, under the elastic force of the elastic separator, the space between the connecting plate 2 and the crushing hood 3 and the dust suction chamber 4 gradually increases, thereby making the dust suction chamber 4 a negative pressure state. Meanwhile, the crushing head 5 moves back into the air extraction hole 30 along with the connecting plate 2. When the dust suction chamber 4 reaches its maximum, the sealing part of the crushing head 5 is pulled out from the air extraction hole 30. Under the action of negative pressure, the dust generated when the air-filled block is crushed is sucked into the dust suction chamber 4. The above repeated movement realizes the crushing of the air-filled block and the elimination of the dust generated by crushing.
