Compared with manual or other sorting methods, the utility model greatly improves efficiency. The utility model completes the sorting of iron objects and the crushing of waste at the same time. Compared with manual selection or other sorting methods, the efficiency is greatly improved and the use of magnetic screening can ensure the complete separation of iron objects;

[0004] Some problems were found during the use of the above-mentioned existing solid waste treatment device. First, the waste is directly added into the equipment through the hopper. There may be a large amount of agglomeration in the waste, and the iron material is wrapped inside the agglomerated waste, which will be difficult to be attracted and separated by magnetic force. At the same time, since the iron material is heavy, it is often in the lower layer during transportation, and a large amount of other waste is piled up on the upper layer, which will also make it difficult to suck out the iron material, and thus lead to the problem of poor separation effect of the equipment. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-3 The utility model provides a technical solution: a solid waste device, including a separation bin 1, a feed hopper 102 is fixedly connected to the separation bin 1, two sets of transmission and sorting mechanisms are arranged in the separation bin 1, the transmission and sorting mechanisms include a conveyor belt 201 and two transmission rollers 205, the transmission rollers 205 are rotatably installed in the separation bin 1, the conveyor belt 201 is sleeved on the transmission rollers 205, and a magnetic strip 202 is adhered to the outer wall of the conveyor belt 201, a crushing shaft 3 is rotatably installed in the separation bin 1 and below the feed hopper 102, and a number of second motors 302 are fixed to the crushing shaft 3, two iron scrapers 4 are fixed in the separation bin 1, and the upper ends of the iron scrapers 4 are in contact with the surface of the magnetic strip 202, and a crusher 5 is fixed below the separation bin 1.

[0022] In this embodiment, waste is added to the separation bin 1 through the feed hopper 102, and the crushing shaft 3 rotates to drive the dispersion knocking head 301 to rotate, and the crushing shaft 3 is rotatably installed under the feed hopper 102. When the crushing shaft 3 drives the dispersion knocking head 301 to rotate, the waste is initially crushed and broken up, and the aggregates in the waste are broken up to facilitate subsequent screening. A plurality of magnetic strips 202 are wound around and fixed on the outer surface of the conveyor belt 201, so that when the waste falls onto the conveyor belt 201 for transmission, the magnetic strips 202 will pull the waste The iron contained in the waste is adsorbed thereon, so that the iron will be transported away with the waste, and the iron scraper 4 is in contact with the surface of the magnetic strips 202 on the two sets of transmission and sorting mechanisms respectively, and both are arranged under the transmission and sorting mechanisms. When the magnetic strips 202 drive the iron to move to the iron scraper 4, the iron scraper 4 can scrape the iron off, thereby achieving the purpose of separating the iron from the waste, and the remaining waste will be directly transported to the inside of the crusher 5, and the crusher 5 can be started to crush the waste.

[0023] Among them, in order to achieve the purpose of transporting waste, this device adopts the following technical solutions: the front and back of the separation bin 1 are symmetrically fixed with support legs 101, discharge holes 105 are opened below the separation bin 1 and on both sides of the crusher 5, discharge plates 106 are fixed on both sides of the crusher 5, a flat scraper 103 is fixed on the top of the separation bin 1, a baffle 104 is fixed on the bottom of the separation bin 1, a first motor 203 is fixed on the front of the separation bin 1, the first motor 203 is fixed to one of the transmission rollers 205, a pulley 204 is fixed to one end of one of the transmission rollers 205 in the preliminary transmission and sorting mechanism and the final transmission and sorting mechanism, and the two pulleys 204 are linked by a belt, a dispersion knocking head 301 is fixed to the front of the separation bin 1, and the output end of the dispersion knocking head 301 is fixed to the crushing shaft 3.

[0024] The support device is at a suitable height through the support legs 101, which is convenient for placing a collection box or a secondary transmission mechanism below. There are two transmission and sorting mechanisms above the discharge hole 105. After the iron scraper 4 scrapes off the iron material, the iron material will directly fall through the discharge hole 105. The flattening scraper 103 is set above the preliminary transmission and sorting mechanism, and the lower end of the flattening scraper 103 is slightly higher than the preliminary transmission and sorting mechanism. Therefore, when the preliminary transmission and sorting mechanism transports waste, the flattening scraper 103 will limit the stacking height above the preliminary transmission and sorting mechanism, and flatten the waste that is too high, so that the waste is spread as flat as possible on the transmission and sorting mechanism. The waste is transported from above and laid flat. First, the waste is prevented from piling up, which causes the iron objects to be on the top and unable to be attracted. Secondly, the waste transportation speed can be controlled to ensure the waste feeding amount of the crusher 5, so that the crusher 5 can work smoothly and stably. The baffle 104 is located on the side of the last transmission and sorting mechanism to prevent the waste from sliding from the last transmission and sorting mechanism and falling into the discharge hole 105 due to inertia. The two sets of transmission and sorting mechanisms cooperate with the pulley 204 through the belt, so that starting the first motor 203 can drive the two sets of transmission and sorting mechanisms to start operation synchronously, and starting the dispersion knocking head 301 is used to drive the crushing shaft 3 to rotate.

[0025] Among them, in order to achieve the purpose of separating iron objects twice, this device adopts the following technical solutions: two groups of transmission and sorting mechanisms are respectively the preliminary transmission and sorting mechanism and the final transmission and sorting mechanism. The preliminary transmission and sorting mechanism is set at 30 degrees below the feed hopper 102, and the final transmission and sorting mechanism is set at 60 degrees on one side of the preliminary transmission and sorting mechanism.

[0026] By setting the initial transmission and sorting mechanism to 30 degrees, the waste that falls on the initial transmission and sorting mechanism can still be driven to move by friction. At the same time, after being resisted by the flattening scraper 103, it can slide down more naturally, making it easier to transport the waste in a flat state. Then the waste will be transmitted to the final transmission and sorting mechanism. The final transmission and sorting mechanism is 60 degrees. When the waste is transported to the final transmission and sorting mechanism, the waste will flip from the initial to the final transmission and sorting mechanism, so that the iron objects on the upper part of the waste will contact the magnetic strip 202 again, thereby adsorbing the iron objects contained in the waste again, and the waste will slide directly downward and fall into the feed inlet of the crusher 5.

[0027] The working principle and usage process of the present invention: When in use, the device needs to be placed in a suitable position, and the dispersing knocking head 301 and the first motor 203 are started separately. The dispersing knocking head 301 will drive the crushing shaft 3 to rotate. After the waste is added into the separation bin 1 through the feed hopper 102, it will first be crushed and scattered by the second motor 302 and then fall onto the preliminary transmission and sorting mechanism. The first motor 203 will drive the two transmission and sorting mechanisms to work. The preliminary transmission and sorting mechanism will transport the waste to the final transmission and sorting mechanism. The waste will slowly slide into the inside of the crusher 5 on the final transmission and sorting mechanism at sixty degrees. The crusher 5 can be started to crush the waste. When the transmission and sorting mechanism transports the waste, the magnetic bar 202 will adsorb the iron contained in the waste on the surface, and it will be scraped off by the iron scraper 4 and fall through the discharge hole 105 and discharged to both sides through the discharge plate 106.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
