[0002] Industrial waste includes construction waste and general waste, while household waste includes kitchen waste and recyclable waste. After recycling, waste is sorted and processed. The more detailed the sorting, the higher the cost and the more difficult the work. To save costs, some industrial waste and some household waste can be processed together. For example, wood from construction waste and wood products, newspapers, and cardboard boxes from household waste can be processed together. Similarly, wood products can be crushed and recycled together, which reduces operating costs and improves work efficiency. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a mixed crushing and pretreatment device for domestic waste and industrial waste, which can mix and process a portion of domestic waste and a portion of industrial waste, thereby improving work efficiency and reducing operating costs.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. Wood-based household waste and industrial waste can be mixed and pre-treated together, reducing the need for sorting household and industrial waste, saving processing costs, and improving waste treatment efficiency;

[0015] 2. The crushing bucket is wider at the top and narrower at the bottom, which can classify and crush waste materials such as wood and boards of different lengths. Under the action of the vibrating motor, shorter wood waste materials can fall to the bottom of the crushing bucket for crushing, longer wood waste materials can be crushed at the top of the crushing bucket, and some smaller wood waste materials can fall to the bottom of the crushing bucket for crushing. This classification crushing method can improve crushing efficiency and avoid the phenomenon of insufficient crushing.

[0016] 3. The crushing bucket can swing, facilitating the feeding of waste materials of different lengths. The recycling bin supports the crushing bucket and provides a sliding track for its smooth swing. Under the influence of magnets, metal parts on wooden waste can enter the recycling bin through the discharge port on the crushing bucket and the long opening on the recycling bin for recycling.

[0017] 4. The suction fan on the side wall of the crushing bucket can suck up lighter wood products such as newspapers to the side of the crushing bucket for crushing, which can greatly improve the crushing efficiency.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] Reference Figure 1-4 As shown, a mixed crushing and pretreatment device for municipal solid waste and industrial waste includes a housing 1. A swingable crushing bucket 2 is installed in the middle of the housing 1. In this embodiment, rotating shafts are provided on both sides inside the housing 1, and rotating sleeves that cooperate with the rotating shafts are symmetrically provided on both sides of the crushing bucket 2. The rotating sleeves are inserted into the rotating shafts to realize the swinging of the crushing bucket 2. In this embodiment, a space is left between the side of the crushing bucket 2 and the housing 1 for the crushing bucket 2 to rotate, and a storage space is left between the bottom of the crushing bucket 2 and the bottom of the housing 1 for the waste to be stored.

[0027] like Figure 1 As shown, a vibration motor 20 is provided on the side of the crushing bucket 2. When wood and waste paper and other wood waste enter the crushing bucket 2, the vibration motor 20 can be started to assist the wood waste in sorting by size. The vibration can make small wood blocks or small paper scraps fall from the gaps to the lower part of the crushing bucket 2, while larger and longer wood blocks remain in the upper part of the crushing bucket 2, so as to achieve the purpose of separating and crushing wood waste by length and size.

[0028] like Figure 2 As shown, the side of the housing 1 is provided with a drive mechanism that can drive the crushing bucket 2 to swing. In this embodiment, the drive mechanism includes two push-pull cylinders 6 symmetrically arranged on the housing 1. The telescopic rods of the two push-pull cylinders 6 pass through the housing 1 and are fixedly connected to the side of the crushing bucket 2. The side of the crushing bucket 2 is symmetrically provided with shock-absorbing sleeves 7, such as... Figure 5 As shown, a damping pad 71 is installed inside the damping sleeve 7. The telescopic rods of the two push-pull cylinders 6 extend into the damping sleeve 7 and contact the damping pad 71. The damping sleeve 7 and the damping pad 71 can prevent the vibration motor 20 from affecting the two push-pull cylinders 6.

[0029] like Figures 1-2 As shown, the diameter of the crushing hopper 2 gradually decreases from top to bottom. Multiple crushing blades 3 are evenly distributed on the inner wall of the crushing hopper 2. This structure allows the wooden waste entering the crushing hopper 2 to move downwards in order of increasing size, and the wooden waste is crushed by the crushing blades 3 during this movement. Multiple longitudinally and transversely arranged receiving beams 4 are spaced at intervals at the bottom of the crushing hopper 2. Multiple crushing blades 3 are evenly distributed on the receiving beams 4. The crushing blades 3 on the receiving beams 4 are densely distributed to prevent waste from falling through gaps. Wooden waste that is not crushed by the side crushing blades 3 during its descent can be further crushed by the crushing blades 3 on the receiving beams 4.

[0030] like Figure 1 and Figure 2 As shown, the side wall of the crushing bucket 2 is provided with a suction structure. In this embodiment, the side wall of the crushing bucket 2 is provided with multiple receiving cavities at intervals. Each receiving cavity is equipped with a suction fan 8. When the suction fan 8 is started, lighter waste products such as waste paper in the crushing bucket 2 can be adsorbed onto the side wall of the crushing bucket 2, which is convenient for the crushing blade 3 to crush and improve the crushing efficiency.

[0031] like Figure 2 As shown, two recycling bins 5 are symmetrically arranged at the bottom of the housing 1. Each recycling bin 5 has an arc-shaped elongated opening 51 on its opposite inner side. The lower sides of the crushing hopper 2 respectively contact the elongated openings 51, and each contact point has a discharge port 21 that can communicate with the elongated openings 51. In this embodiment, the recycling bins 5 support the crushing hopper 2, improving the installation strength of the crushing hopper 2. The two arc-shaped elongated openings 51 can serve as slides for the crushing hopper 2. By sliding the crushing hopper 2 on the elongated openings 51, the tilt angle of the crushing hopper 2 can be adjusted, and the stability of the crushing hopper 2's swing can be ensured. In this embodiment, the contact surface between the elongated openings 51 and the crushing hopper 2 is a smooth surface to avoid friction during sliding.

[0032] like Figure 1 As shown, magnets are installed on the inner walls of both the discharge port 21 and the recycling bin 5. Wood waste may contain scrap iron such as screws and iron sheets. When this scrap iron falls to the bottom of the crushing hopper 2, it can be recycled into the recycling bin 5 under the action of the magnets. The magnetic induction intensity of the magnet located on the inner wall of the recycling bin 5 is greater than that of the magnet located on the inner wall of the discharge port 21. This arrangement prevents scrap iron from accumulating at the discharge port 21, ensuring that the scrap iron is fully recycled into the recycling bin 5.

[0033] like Figures 1-2As shown, the bottom of the box body 1 is provided with support legs 11, and the bottom of the box body 1 is provided with a discharge port corresponding to the bottom of the crushing hopper 2. The bottom of the box body 1 is hinged with a cover 13 that can seal the discharge port. In this embodiment, the cover 13 is provided with a handle. The hinge structure between the cover 13 and the box body 1 and the sealing connection between the cover 13 and the discharge port are existing technologies and will not be described in detail here. After long-term crushing, the cover 13 can be opened to recycle the waste material accumulated in the storage space.

[0034] like Figure 1 As shown, the top of the box 1 is provided with a crossbeam 14, and a control cylinder 15 is installed on the lower surface of the crossbeam 14. The end of the telescopic rod of the control cylinder 15 is provided with a cover 9 that can seal the top of the crushing bucket 2. In this embodiment, the cover 9 can cover the opening of the crushing bucket 2 and can also cover the vibration motor 20, thereby achieving the effect of dust prevention and noise reduction.

[0035] In this embodiment, a controller is installed on the housing 1, which is electrically connected to electrical components such as the vibration motor 20, push-pull cylinder 6, suction fan 8, and control cylinder 15.

[0036] Working process: Waste wood and paper are placed into the crushing hopper 2. Under the action of the vibrating motor 20, shorter pieces of wood fall to the bottom of the crushing hopper 2, while longer pieces remain at the top. Because the crushing hopper 2 is conical, wider at the top and narrower at the bottom, longer boards or pieces of wood can be crushed gradually from top to bottom and from long to short, improving crushing efficiency. Under the action of the suction fan 8, lighter waste is drawn to the side of the crushing hopper 2, allowing the crushing blades 3 on the side of the crushing hopper 2 to fully crush the waste, while also preventing dust from escaping from the crushing hopper 2 and polluting the environment. Some waste that cannot be crushed by the crushing blades 3 on the side of the crushing hopper 2 falls onto the receiving beam 4, where it continues to be crushed by the crushing blades 3, further improving the crushing effect. In addition, the vibrating motor 20 also promotes the crushed waste to fall to the bottom of the crushing hopper 2, preventing blockages. During use, the tilting angle of the crushing hopper 2 can be adjusted as needed. For example, if the wooden waste is too long, the push-pull cylinder 6 can be activated, extending the extension rod of one side of the cylinder and retracting the extension rod of the other side, pushing and pulling the crushing hopper 2 so that its bottom slides on the long opening 51 of the recycling box 5, forming an inclined state to facilitate the dumping of waste. During the crushing process, the crushing hopper 2 is kept perpendicular to the horizontal plane. At this time, the control cylinder 15 can be activated to lower the cover 9 and cover the opening of the crushing hopper 2, preventing dust from escaping and noise pollution. After a long period of accumulation, the cover 13 can be opened to recycle the crushed waste in the storage space, and the scrap iron in the recycling box 5 can also be recycled from the long opening 51.
