Description

Technical Field

[0001] The utility model relates to the technical field of metal waste recycling, in particular to a garbage crushing device for recycling metal waste. Background Art

[0002] Metal waste recycling technology is a common waste disposal technology. It crushes the garbage and then extracts the high-value metal waste from the crushed garbage through screening for recycling. When recycling metal waste, a garbage crushing device is needed.

[0003] In the prior art, such as publication number CN218532294U, a garbage crushing device is disclosed, which includes a shell, a feed port is fixedly installed on the upper end of the shell, a crushing mechanism is fixedly installed on the upper part of the inner cavity of the shell, a stirring mechanism is fixedly installed in the middle part of the inner cavity of the shell, the stirring mechanism is located directly below the crushing mechanism, a non-metallic garbage outlet is fixedly installed on the left side of the lower inner cavity of the shell, a metal collecting device is fixedly installed on the right side of the non-metallic garbage outlet, and a transmission mechanism is fixedly installed on the rear end of the shell. The garbage crushing device described in the present utility model is provided with a conveyor belt and an electromagnetic plate. The garbage debris crushed by the upper crushing roller will fall downward, and the metal garbage debris therein will be attracted to the belt on the surface of the conveyor belt by the electromagnetic plate. The belt drives the metal garbage debris to be hung by the scraper and fall on the baffle, and finally fall downward for easy collection. The non-metallic garbage debris directly falls from the belt to the non-metallic garbage outlet.

[0004] However, the device still has some problems. The metal waste fragments are adsorbed on the conveyor belt through the cooperation of the conveyor belt and the electromagnetic plate, and then the metal waste fragments are scraped off by the scraper through the belt and fall on the baffle, and finally fall down for collection. However, in actual use, when the scraper recycles the metal waste adsorbed on the conveyor belt, the metal waste adsorbed on its surface cannot be completely scraped off by just scratching. Some small metals will continue to be adsorbed on the conveyor belt due to their small size, resulting in insufficient force applied by the scraper. As the small metal waste continues to surge, it will block the scraping surface of the scraper, resulting in the scraper being unable to contact the larger metal. In this way, the subsequent metal cannot be cleaned, resulting in the problem of poor metal recovery efficiency. Therefore, we disclose a garbage crushing device that can recycle metal waste to meet people's needs. Utility Model Content

[0005] The purpose of the present application is to provide a garbage crushing device that can recycle metal waste, so as to solve the problem raised in the above background technology that when the scraper recycles the metal waste adsorbed on the conveyor belt, the metal waste adsorbed on its surface cannot be completely scraped off by just scratching it. Some fine metals will continue to be adsorbed on the conveyor belt due to their small size, resulting in insufficient force applied by the scraper. As the fine metal waste continues to increase, it will block the scraping surface of the scraper, resulting in the scraping surface of the scraper being unable to contact the larger metal, so that the subsequent metal cannot be cleaned, resulting in poor metal recovery efficiency.

[0014] 1. In the present invention, the first drive roller is driven to rotate by the first drive motor, and the second drive roller is driven to rotate by the second drive motor.

[0024] A waste shredding device for recycling metal waste includes a shredding box 1. A rotating hole is defined in the sidewall of the shredding box 1, and two shredding rollers 2 are mounted in each of the rotating holes. A shredding motor 3 is mounted on the other side of the shredding box 1. The output shaft of the shredding motor 3 is coaxially mounted with one end of one of the shredding rollers 2. Gears are mounted on the surfaces of both shredding rollers 2 and mesh with each other. The output shaft of the shredding motor 3 drives one of the shredding rollers 2 to rotate, thereby driving the other shredding roller 2 to rotate in the opposite direction for shredding. The shredding box 1 also has a rotating hole, and a scattering roller 4 is rotatably mounted in the rotating hole, with the scattering roller 4 positioned below the shredding rollers 2.

[0025] A screening box 5 is mounted on the lower side of the crushing box 1. Several electromagnets 10 are mounted on the inner wall of the screening box 5. A first sliding opening is provided on one side of the screening box 5, and a second sliding opening is provided on the other side of the crushing box 1. A first drive hole is provided on the side wall of the screening box 5, in which a first drive roller 6 is rotatably mounted. A second drive hole is also provided on the side wall of the screening box 5, in which a second drive roller 8 is rotatably mounted. A transmission roller 7 is rotatably mounted on the inner wall of the screening box 5. A first drive motor 13 and a second drive motor 14 are mounted on the side wall of the crushing box 1. The output shaft of the first drive motor 13 is coaxially connected to the first drive roller 6, and the output shaft of the second drive motor 14 is coaxially connected to the second drive roller 8. A conveyor belt 9 is sleeved around the first drive roller 6, the second drive roller 8, and the transmission roller 7. The first drive motor 13 and the second drive motor 14 respectively drive the first drive roller 6 and the second transmission roller 7, providing better transmission power for the conveyor belt 9.

[0026] Based on the above structure, the mounting structure of the two crushing rollers 2 is consistent with the crushing roller 2 structure used in the aforementioned references. The two crushing rollers 2 rotate in opposite directions within the box to crush the garbage. The scattering roller 4 is located below the crushing rollers 2 and has a motor installed at one end. The motor drives the scattering roller 4 to scatter the crushed garbage. The first drive roller 6, the second drive roller 8, and the transmission roller 7 form a triangular structure, and the surface of the first drive roller 6, the second drive roller 8, and the transmission roller 7 are mounted on the same conveyor belt 9. The surface of the conveyor belt 9 is provided with a number of small pits to prevent metal from slipping on the conveyor belt 9. The inner area of ​​the conveyor belt 9 is provided with a number of electromagnets 10. When the device is in use, the garbage to be crushed is poured into the crushing box 1 and crushed by the crushing rollers 2. The crushed garbage is scattered by the scattering rollers 4 and falls onto the conveyor belt 9. The metal garbage on the conveyor belt 9 is attracted by the electromagnets 10, and the metal garbage that is not attracted rolls to the inner wall of the screening box 5. The attracted metal garbage is collected separately by the reverse rotation of the conveyor belt 9.

[0027] Several electromagnets 10 are installed between the first drive roller 6 and the second drive roller 8, and the electromagnets 10 are installed between the first drive roller 6 and the transmission roller 7. The second drive roller 8 and the transmission roller 7 are at the same horizontal plane and lower than the first drive roller 6. The electromagnets 10 neatly arranged between the first drive roller 6 and the second drive roller 8 are parallel to the conveyor belt 9 on their upper side. The purpose is to provide a stable magnetic field for metal adsorption. The electromagnets 10 installed between the first drive roller 6 and the transmission roller 7 are used to adsorb metal vertically downward to prevent it from falling directly and affecting collection. Metal garbage will be adsorbed in the conveyor belt 9 area between the first drive roller 6 and the second drive roller 8 and the second drive roller 8 and the transmission roller 7, but when entering the area between the second drive roller 8 and the transmission roller 7, the magnetic field effect of the electromagnet will be lost, and the adsorbed metal garbage will fall into the collection area.

[0028] like Figure 3 and 4 As shown, a transmission hole is provided on one side of the screening box 5, in which a transmission rod 11 is rotatably installed. A plurality of toggle blocks 12 are installed on the surface of the transmission rod 11. The toggle blocks 12 correspond to the conveyor belt 9, which is made of rubber material. When the toggle blocks 12 toggle it, the surface of the conveyor belt 9 will vibrate, cleaning the metal debris on its surface.

[0029] A drive gear 15 is mounted on one end of the second drive roller 8, and a transmission gear 16 is mounted on one end of the transmission rod 11. The drive gear 15 meshes with the transmission gear 16. A metal waste collection box 18 is slidably mounted in the first sliding opening, and a other waste collection box 17 is slidably mounted in the second sliding opening. The metal waste collection box 18 is located in the area between the second drive roller 8 and the transmission roller 7, and the other waste collection box 17 is located in the area where the second drive roller 8 is located.

[0030] By activating several electromagnets 10, the crushed metal waste is absorbed, while non-metallic waste falls into other collection boxes 17 due to gravity. When the metal waste is conveyed between the conveyor roller 7 and the second drive roller 8, the magnetic force disappears and it falls into the metal collection box 18 for collection, thus preventing the accumulation of small metal debris and the subsequent inability to clean the metal. The second drive roller 8 rotates the drive gear 15, which in turn rotates the transmission gear 16, which in turn rotates the transmission rod 11. The transmission rod 11 drives the wave block on its surface to slightly vibrate the surface of the conveyor belt 9, causing the stubborn metal debris adsorbed on the surface to fall through the vibration, thereby further cleaning the surface of the conveyor belt 9 and improving recycling efficiency.

[0031] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
