DETAILED DESCRIPTION

[0032] 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, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other without conflict.

[0033] like Figure 1-Figure 8 As shown, an embodiment of the present invention provides a crushing device for solid waste resource processing, including: an outer shell 1 and a crushing member 2, the outer shell 1 is a columnar structure with an inner cavity; the crushing member 2 is arranged in the inner cavity of the outer shell 1, and can be driven to rotate relative to the outer shell 1; the gap between the inner wall of the outer shell 1 and the outer wall of the crushing member 2 forms a crushing cavity that can receive external solid waste, the solid waste in the crushing cavity is crushed under the rotation of the crushing member 2, and the size of the crushed product corresponds to the size of the crushing cavity, and the size of the crushing cavity can be adjusted according to user needs, so that the size of the crushed product meets user needs.

[0034] In the above embodiment, the crushing device for solid waste resource processing is provided with a crushing chamber with an adjustable size, so that the size of the target crushed product can be adjusted, thereby making the crushing device for solid waste resource processing highly flexible and able to produce crushed products of corresponding sizes according to user needs. It has the advantage of customer customization and has broad application prospects.

[0035] like Figure 1As shown, in the embodiment of the present invention, the crushing chamber includes an upper air chamber 3 and a lower air chamber 4 formed in the axial direction. The size of the upper air chamber 3 is fixed, and the size of the lower air chamber 4 can be adjusted. The upper air chamber 3 and the lower air chamber 4 are set to form two crushing of solid waste. The first crushing can effectively destroy the stability of the internal structure of the solid waste and decompose the larger solid waste into smaller substances. The second crushing further crushes the first crushed substances into smaller substances. Compared with the one-time crushing of the prior art, the two crushings are more sufficient and thorough for the solid waste, not only to obtain finer crushed products, but also to make the size of the crushed products more evenly distributed, thereby improving the utilization rate of the crushed products.

[0036] Among them, the shell 1 includes an upper end 5 and a lower end 6, the gap between the inner wall of the upper end 5 of the shell 1 and the outer wall of the crushing member 2 forms an upper air cavity 3, and the gap between the inner wall of the lower end 6 of the shell 1 and the outer wall of the crushing member 2 forms a lower air cavity 4.

[0037] like Figure 1 and Figure 3 As shown, in a preferred embodiment, the lower end portion 6 is composed of a plurality of controllable arc-shaped blades 7, and the arc-shaped blades 7 can be driven to approach and move away from the crushing member 2. By means of the approach and movement of the arc-shaped blades 7, the lower end portion 6 performs an inward contraction movement and an outward expansion movement.

[0038] In a specific embodiment, when the arc-shaped blade 7 approaches the crushing member 2, the lower end portion 6 contracts inward, the inner wall of the lower end portion 6 approaches the outer wall of the crushing member 2, the volume of the lower air cavity 4 becomes smaller, and the crushed product obtained at this time is smaller; when the arc-shaped blade 7 moves away from the crushing member 2, the lower end portion 6 expands outward, the inner wall of the lower end portion 6 moves away from the outer wall of the crushing member 2, the volume of the lower air cavity 4 becomes larger, and the crushed product obtained at this time is larger. The size of the lower air cavity 4 is adjusted by controlling the movement of the arc-shaped blade 7.

[0039] like Figure 1 and Figure 4 As shown, in the embodiment of the present invention, a through hole is provided on the arc-shaped blade 7, and a guide column 8 is fixed in the through hole. Specifically, the guide column 8 can be installed in the through hole by threaded connection or by welding. The length of the guide column 8 is greater than the thickness of the arc-shaped blade 7, so that the upper and lower ends of the guide column 8 after installation extend out of the through hole respectively, so that the guide column 8 can slide in the guide groove. Through the repeated sliding of the guide column 8, the arc-shaped blade 7 approaches and moves away from the crushing member 2, thereby adjusting the size of the lower air cavity 4. The upper part of the guide column 8 forms an upper end guide column, and the lower part forms a lower end guide column.

[0040] In the embodiment of the present invention, a chassis 9 which can be driven to rotate is further included, and the guide column 8 slides in the guide groove through the rotation of the chassis 9.

[0041] like Figure 4 , Figure 7 and Figure 8 As shown, in a preferred embodiment, the guide groove includes a guide groove 10 and a guide groove 2 11, and the guide groove 10 and the guide groove 2 11 intersect in a horizontal projection plane.

[0042] In this embodiment, since the guide groove 10 and the guide groove 2 11 intersect in the horizontal projection plane, the guide groove 10 and the guide groove 2 11 form a certain angle in space, thereby forming a skew groove relationship. When the chassis 9 is driven to rotate, under the rotation of the chassis 9, the upper end and the lower end of the guide column 8 slide in the guide groove 10 and the guide groove 2 11 at the same time. Due to the constraint of the skew grooves, when the guide column 8 slides back and forth in the guide groove 10 and the guide groove 2 11 at the same time, it will cause the arc blade to approach and move away from the crushing member 2, thereby being able to adjust the size of the lower air cavity 4.

[0043] like Figure 1 , Figure 7 and Figure 8 As shown, in the embodiment of the present invention, guide groove 10 is arranged on the lower end surface of the upper end portion 5, guide groove 2 11 is arranged on the upper end surface of the chassis 9, the upper end of the guide column 8 is located in the guide groove 10, and the lower end of the guide column 8 is located in the guide groove 2 11.

[0044] like Figure 1 As shown, in a preferred embodiment, in order to improve the squeezing effect on the solid waste, the outer shell 1 is provided with a plurality of inner flanges 12 in the axial direction of its inner cavity, and the crushing member is spirally wound with an outer flange 13 from top to bottom along its outer wall, and the outer flange 13 corresponds to all or part of the inner flange 12. In this embodiment, the outer flange 13 and the inner flange 12 can enhance the squeezing of the solid waste, and the squeezing forms a shear force with great destructive power, which can quickly destroy the stable structure inside the solid waste and thus improve the crushing efficiency. Preferably, when the outer flange 13 corresponds to the inner flange 12, the squeezing is the strongest, the shear force generated is the largest, and the destructive effect is the best.

[0045] In the embodiment of the present invention, the inner flange 12 is located on the inner wall of the upper end portion 5 and the inner wall of the lower end portion 6, wherein the inner wall of each arcuate blade 7 constitutes the inner wall of the lower end portion 6, and when the arcuate blade 7 approaches and moves away from the crushing member 2, the inner flange 12 arranged on the inner wall thereof will not hinder the movement of the arcuate blade 7, that is, the inner flange 12 on the arcuate blade 7 will not have any effect on the inward contraction and outward expansion of the lower end portion 6.

[0046] like Figure 1As shown, in the embodiment of the present invention, an annular upper cover 14 with a slope is arranged above the outer shell 1, and the space between the inner wall of the annular upper cover 14 and the outer wall of the central rotating shaft 16 of the crushing member 2 forms a accommodating chamber 15 for receiving external solid waste input, and the accommodating chamber 15 is connected with the upper air chamber 3 of the crushing chamber, and the solid waste in the accommodating chamber 15 is introduced into the upper air chamber 3 for crushing.

[0047] In this embodiment, the slope of the annular upper cover 14 determines the size of the accommodating chamber 15, wherein the smaller the slope, the larger the accommodating chamber 15 is, and thus it can accept larger solid waste; on the contrary, the larger the slope, the smaller the accommodating chamber 15 is, and thus the size of the solid waste accepted is limited, so the corresponding slope can be designed according to actual needs.

[0048] like Figure 2 As shown, in a preferred embodiment, a sawtooth 17 is provided on the circular end face of the chassis 9, and the chassis 9 is meshed with a driving gear 18 through the sawtooth 17. A handle 19 is provided on the end face of the driving gear 18. Turning the handle 19 can rotate the driving gear 18, thereby driving the chassis 9 to rotate.

[0049] In the embodiment of the present invention, a supporting member is further included, on which a chassis 9 and a driving gear 18 are arranged, wherein the chassis 9 and the driving gear 18 can rotate independently relative to the supporting member.

[0050] In the embodiment of the present invention, the central rotating shaft 16 of the crushing member 2 is connected to the output shaft of the servo motor, so that the crushing member 2 is driven to rotate under the power output of the servo motor.

[0051] In another embodiment, the central rotating shaft 16 of the crushing member 2 is fixedly provided with a gear ring, and the central rotating shaft 16 is meshed with a main gear with a central through hole through the gear ring. The output shaft of the servo motor is connected to the central through hole of the main gear, so that under the power output of the servo motor, the power is transmitted through gear meshing to drive the crushing member 2 to rotate.

[0052] In order to better understand the solution of the present invention, its specific working method is as follows:

[0053] First, the volume of the crushed product is determined according to user needs, and the volume of the lower air cavity 4 is further determined, and the determined volume of the lower air cavity 4 is compared with the volume of the lower air cavity 4 in the initial state. When the volume of the lower air cavity 4 in the initial state is larger than the determined volume of the lower air cavity 4, it is necessary to reduce the volume of the lower air cavity 4, and the driving gear 18 is rotated by turning the handle 19. Under the action of the gear coupling, the chassis 9 is driven to rotate. Under the rotation of the chassis 9, the guide column 8 on the arc-shaped blade 7 will slide simultaneously in the guide groove 2 11 on the upper end face of the chassis 9 and the guide groove 1 10 on the lower end face of the upper end portion 5. Since the guide groove 2 11 and the guide groove 10 intersect on the horizontal projection plane, they form a certain angle in space, thereby forming eccentric grooves. Under the restriction of the eccentric grooves, the arc-shaped blade 7 approaches or moves away from the crushing member 2. When the arc blade 7 approaches the crushing member 2, the lower end 4 makes an inward contraction movement, and the volume of the lower air cavity 4 becomes smaller until it becomes the same as the determined volume of the lower air cavity 4, then the handle 19 is stopped and the chassis 10 stops rotating; and when the arc blade 7 moves away from the crushing member 2, it is necessary to adjust the rotation direction of the chassis 9, and the chassis 9 is rotated in the opposite direction by reversing the handle 19, so that the arc blade 7 approaches the crushing member 2, and the volume of the lower air cavity 4 becomes smaller until it becomes the same as the determined volume of the lower air cavity 4, then the handle 19 is stopped and the chassis 10 stops rotating. After the volume of the lower air cavity 4 is adjusted, the crushing member 2 is driven to rotate by the servo motor, and the solid waste is placed into the accommodating cavity 15 through the annular upper cover 14, and then enters the upper air cavity 3 for the first crushing, and the crushed product enters the lower air cavity 4 for the second crushing. When the crushing is completed, a crushed product that meets the user's needs is obtained. On the contrary, when the volume of the lower air cavity 4 in the initial state is smaller than the determined volume of the lower air cavity 4 , the volume of the lower air cavity 4 needs to be increased. The implementation method is similar to the above and will not be elaborated in detail.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
