[0005] Furthermore, the dust removal equipment includes a dust suction pipe, an induced draft fan and a storage box; the dust suction pipe is connected to the induced draft fan and extends into the storage box.

[0006] Furthermore, a funnel-shaped filter is provided on one side of the dust suction pipe connected to the air outlet.

[0007] Furthermore, the magnetic net is inserted from the installation port and arranged parallel to the discharge plate, and a fixed strip is provided on one side of the magnetic net.

[0008] Furthermore, a small sprayer is provided on the inner wall above the feed inlet.

[0009] The beneficial effects of the utility model are: the device can prevent dust particles generated by solid crushing from spreading into the air, prevent environmental pollution, and maintain the health of users; the bottom vibration motor drives the magnetic suction net to vibrate, so that it can absorb and filter out metal substances in the waste, avoiding the waste of metal resources.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figures 1 to 4The solid waste crushing device shown in the figure comprises a crushing box 11; a feed port 1 is provided at the top of the crushing box 11, a crushing roller 3 is provided inside the crushing box 11; a collection box 7 is provided at the bottom of the crushing box 11; the collection box 7 can be freely taken in and out; a discharge plate 4 is provided below the crushing roller 3; there are two symmetrically arranged discharge plates 4, and there is an inclination angle between the discharge plates 4 and the side wall of the crushing box 11; the discharge plates 4 are fixedly connected to the inner wall of the crushing box 11, and a mounting port 8 is provided on the upper part of the box wall where the two intersect; a magnetic suction is provided on the discharge plate 4 Filter screen 5; the magnetic filter screen 5 is a mesh three-dimensional structure composed of multiple layers of magnetic screens stacked together; the bottom surface of the discharge plate 4 is fixedly connected to the vibration motor 6; after the vibration motor 6 is turned on, it drives the discharge plate 4 and the magnetic filter screen 5 to vibrate, and the crushed solid waste is filtered. At the same time, the magnetic screen absorbs metal substances in the waste to reduce the waste of resources; an air outlet 9 is provided on the side wall of the crushing box 11 below the feed port 1, and the air outlet 9 is connected to the dust removal equipment 2, which can absorb the generated dust as soon as possible after the crushing.

[0018] The dust removal equipment 2 includes a dust suction pipe 21, an induced draft fan 22 and a storage box 23; the dust suction pipe 21 is connected to the induced draft fan 22 and extends into the storage box 23; after the induced draft fan 22 is started, the dust particles in the crushing box 11 are extracted and fall into the storage box 23 below, reducing air pollution.

[0019] A funnel-shaped filter 20 is provided on one side of the dust suction pipe 21 connected to the air outlet 9; the filter mainly filters light and large materials, such as paper, plastic bags, etc., to prevent such items from being accidentally sucked into the induced draft fan and causing damage to the machine body.
