DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 this field without creative work are within the scope of protection of the present invention.

[0017] An electronic solid waste recycling and crushing device, such as Figure 1 , 2 As shown in , 3, 4, and 5, it includes a box body 1, a feeding port 2 is provided on the top side of the box body 1, a discharge port 3 is provided at the bottom of the box body 1, two crushing rollers 4 are rotatably installed on the upper part of the box body 1, a driving motor 5 for driving the crushing rollers 4 to rotate is provided on the box body 1, and arc plates 6 fixed on the box body 1 are provided below the crushing rollers 4, and the two arc plates 6 are connected by a mesh plate 7, and the arc plates 6 and the mesh plates 7 divide the box body 1 into a feeding chamber and a discharge chamber, and the feeding chamber and the discharge chamber are only connected through the filter holes on the mesh plate 7, and the crushing teeth of the crushing roller 4 are in gap with the corresponding arc plates 6. The present invention has a simple structure and an ingenious design. The coarse crushing device is used to repeatedly crush the solid waste until the crushing grade requirement is met, and the crushing teeth are used to move the incompletely crushed solid waste to make the solid waste repeatedly crushed. At the same time, the crushed solid waste is continuously screened and filtered to reduce the influence of the completely crushed solid waste on the subsequent crushing, thereby completing the crushing. The coarse crushing device is more durable than the fine crushing device, and the service life of the device is extended. When using the present invention, firstly, the driving motor 5 is energized, and the driving motor 5 drives the crushing roller 4 to rotate, the crushing roller 4 on the left rotates clockwise, and the crushing roller 4 on the right rotates counterclockwise, and then the electronic solid waste to be crushed is put into the box 1 through the feeding port 2, and the crushing roller 4 crushes the solid waste, and the crushed solid waste falls on the mesh plate 7. After filtering and screening by the mesh plate 7, the completely crushed solid waste falls to the lower part of the box 1, and the completely crushed solid waste can be moved out of the box 1 through the discharge port 3. The incompletely crushed solid waste remains on the mesh plate 7 and is moved by the crushing teeth of the crushing roller 4. After sliding along the arc plate 6, it reaches the top of the crushing roller 4 again and is crushed again. After being completely crushed, it can fall to the lower part of the box 1 through the filtering holes of the mesh plate 7.

[0018] Specifically, as shown in the figure, the outer circumference of the crushing roller 4 described in this embodiment is evenly provided with several rows of crushing teeth, and the crushing teeth in the same cross section of the crushing roller 4 are evenly distributed circumferentially, and each row of crushing teeth includes fixed crushing teeth 20 and movable crushing teeth 21, and the fixed crushing teeth 20 and the movable crushing teeth 21 are cross-distributed; the outer circumference of the crushing roller 4 is respectively provided with slots 22 corresponding to the movable crushing teeth 21, and the movable crushing teeth 21 are slidably installed in the corresponding slots 22, and the crushing teeth 21 can only move along the radial direction of the corresponding crushing roller 4, and the movable crushing teeth 21 cannot be removed from the slots 22, and the end of the movable crushing tooth 21 away from the crushing roller 4 is the outer end, and the other end is the inner end, and the outer circumference of the movable crushing tooth 21 is in sliding contact with the inner circumference of the slot 22. When the crushing roller 4 rotates, the movable crushing teeth 21 rotates with the crushing roller 4. When the movable crushing teeth 21 is located below the crushing roller 4, the movable crushing teeth 21 slide outward along the radial direction of the crushing roller 4 under the action of its own gravity, and the movable crushing teeth 21 gradually approach the mesh plate 7 and the arc plate 6 until the movable crushing teeth 21 extend to the outermost end. The portion where the movable crushing teeth 21 extend out of the slot 22 is the same size as the fixed crushing teeth 20. The movable crushing teeth 21 and the fixed crushing teeth 21 in the same row cooperate with each other to form a scraper. The scraper can move the incompletely crushed solid waste above the mesh plate 7 to the arc plate 6 and slide along the arc plate 6, so that the incompletely crushed solid waste returns to the top of the crushing roller 4 again and is crushed again until the solid waste is completely crushed. The solid wastes are filtered through the filter holes of the mesh plate 7 and fall to the lower part of the box body 1; when the movable crushing tooth 21 is located above the crushing roller 4, the movable crushing tooth 21 slides radially inward along the crushing roller 4 under the action of its own gravity, and the movable crushing tooth 21 gradually retracts into the crushing roller 4. In the process of extending and retracting the movable crushing tooth 21 into the slot 22, the slot 22 can scrape off the solid wastes attached to the periphery of the movable crushing tooth 21, and clean the movable crushing tooth 21. At the same time, when the movable crushing tooth 21 slides between the fixed crushing teeth 20, it can also push off the solid wastes on the periphery of the fixed crushing teeth 20, and clean the fixed crushing teeth 20; when the movable crushing tooth 21 is retracted into the crushing roller 4, the fixed crushing teeth 20 and the movable crushing teeth 21 no longer form a scraper, thereby reducing the influence of the movable crushing tooth 21 on crushing.

[0019] Specifically, as shown in the figure, the side of the movable crushing tooth 21 of this embodiment is provided with a strip-shaped slide groove 30, and a slide rod 31 is slidably installed in the strip-shaped slide groove 30, and the slide rod 31 is fixed on the corresponding crushing roller 4. When the movable crushing tooth 21 slides in the corresponding slot 22, the slide rod 31 slides along the corresponding strip-shaped slide groove 30, and when the slide rod 31 is located at the end of the corresponding slide groove 31, the outer end of the movable crushing tooth 21 will not be completely retracted into the slot 22, and the inner end of the movable crushing tooth 21 will not be completely retracted into the slot 22, thereby avoiding the formation of a gap between the movable crushing tooth 21 and the slot 22.

[0020] Further, as shown in the figure, the fixed crushing teeth 20 on the crushing rollers 4 on the left and right sides of this embodiment are mutually offset front and back, and the fixed crushing teeth 20 on the crushing roller 4 on one side can be inserted between the two fixed crushing teeth 20 adjacent to each other on the crushing roller 4 on the other side. When the fixed crushing teeth 20 on the crushing rollers 4 on the left and right sides are close to each other, the fixed crushing teeth 20 on the crushing rollers 4 on the left and right sides are staggered with each other, and the fixed crushing teeth 20 on the left side can push the movable crushing teeth 21 on the right side into the crushing roller 4, and the fixed crushing teeth 20 on the right side can push the movable crushing teeth 21 on the left side into the crushing roller 4. The fixed crushing teeth 20 on the crushing rollers 4 on the left and right sides mesh with each other, which can increase the crushing effect of the fixed crushing teeth 20 and make the solid waste crushing more thorough. At the same time, the fixed crushing teeth 20 can push the movable crushing teeth 21 into the crushing roller 4, increase the smoothness of the movable crushing teeth 21 sliding in the slot 22, and prevent the movable crushing teeth 21 from being stuck by the solid waste and unable to retract normally into the crushing roller 4.

[0021] Furthermore, as shown in the figure, the crushing roller 4 described in this embodiment is hollow inside, the slots 22 are respectively connected to the hollow inside the crushing roller 4, a coaxial cylindrical airbag 50 is provided inside the crushing roller 4, and the inner ends of the movable crushing teeth 21 are respectively in contact with the outer periphery of the cylindrical airbag 50. After the cylindrical airbag 50 is filled with gas and expanded, the outer periphery of the cylindrical airbag 50 provides an outward supporting force to the inner end of the movable crushing tooth 21, so that the fixed crushing tooth 20 and the movable crushing tooth 21 effectively form a scraper, which can better scrape and lift the solid waste that has not been completely crushed on the upper side of the arc plate 6; at the same time, when the scraper passes over the mesh plate 7, it can move the solid waste, reduce the accumulation of crushed solid waste, and facilitate the crushed solid waste to pass through the filtering holes of the mesh plate 7, thereby increasing the filtering efficiency; when the fixed crushing tooth 20 squeezes the movable crushing tooth 21 and moves the movable crushing tooth 21 toward the inside of the crushing roller 4, the inner end of the movable crushing tooth 21 squeezes the cylindrical airbag 50, and the cylindrical airbag 50 undergoes elastic deformation. When the movable crushing tooth 21 is separated from the fixed crushing tooth 20, the movable crushing tooth 21 moves outward and resets under the elastic thrust of the cylindrical airbag 50.

[0022] Further, as shown in the figure, one end of the crushing roller 4 of this embodiment is provided with a through hole 60, and an air intake check valve 61 is provided in the through hole 60, and the air intake check valve 61 is respectively connected to the corresponding cylindrical airbag 50. The air intake check valve 61 can be used to add air or release air into the cylindrical airbag 50, thereby controlling the expansion degree of the cylindrical airbag 50, and further controlling the force with which the movable crushing teeth 21 are compressed into the crushing roller 4.

[0023] Furthermore, as shown in the figure, the driving motor 5 described in this embodiment is fixed on the housing 1 through a bracket, and the housing 1 is provided with through slots 70 corresponding to the crushing rollers 4, and the two ends of the crushing rollers 4 extend out of the housing 1 through the through slots 70, respectively. The crushing rollers 4 are rotatably installed in the through slots 70, and the two ends of the outer periphery of the crushing rollers 4 are rotatably connected to the corresponding through slots 70 through sealed bearings, respectively. The output shaft of the driving motor 5 is fixedly connected to one of the crushing rollers 4, and the crushing roller 4 is coaxially arranged with the output shaft of the driving motor 5, and the ends of the crushing rollers 4 are respectively fixedly provided with coaxial toothed rings 71, and the two toothed rings 71 are meshed with each other. When the driving motor 5 is energized, it drives one of the crushing rollers 4 to rotate, and the crushing roller 4 drives the other crushing roller 4 to rotate in the opposite direction through the meshing toothed rings 71.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
