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.
[0022] See also Figure 1-3 The utility model provides a technical solution: a double-shaft shredder with a protective structure, comprising a box body 1, the lower end of the box body 1 is connected with a tapered channel 2, and the lower end of the tapered channel 2 is connected with a shredding square tube 3, the inner cavity of the shredding square tube 3 is provided with two groups of shredding mechanisms 4, and a connecting hole 7 for connecting with a protective mechanism 6 is opened at the upper end of one side of the box body 1;
[0023] The protective mechanism 6 includes a connecting square tube 61, one side of which is provided with an electric push rod 63, and the telescopic rod of the electric push rod 63 passes through the connecting square tube 61 and is fixedly connected to a push plate 64, the upper surface of the connecting square tube 61 is provided with a first opening 611, and one side of the inner cavity of the first opening 611 is hinged with a first flip cover 62 through a plurality of combination pages, and two groups of fixed blocks 14 are symmetrically welded to the upper end of one side of the inner cavity of the box body 1 close to the connecting hole 7, and the opposite sides of the two groups of fixed blocks 14 are hinged with protective plates 13.
[0024] When in use, the first flip cover 62 is opened to place the material in the inner cavity of the connecting square tube 61 through the first opening 611, and the electric push rod 63 is started to drive the push plate 64 to push the material into the inner cavity of the box body 1 through the connecting hole 7. The protective plate 13 is turned over with the fixed block 14 as the axis, so that the connecting square tube 61 is connected with the inner cavity of the box body 1, which is convenient for the material to fall into the inner cavity of the box body 1, and the push plate 64 can prevent small materials from being stuck between the protective plate 13 and the connecting square tube 61 through the triangular plate 65, thereby improving the feeding efficiency of the material, and When the material is shredded by the double-shaft shredder, the shredded material generates waste debris that splashes and is blocked by the protective plate 13 and the box body 1, thereby preventing the waste debris from splashing and injuring the staff, thereby improving the overall safety performance of the equipment. At the same time, water is passed through the water inlet pipe 10 to the water pipe 11, and the water pipe 11 supplies water to the atomizing nozzle 12. The water mist sprayed by the multiple groups of atomizing nozzles 12 is used to reduce the dust generated when the material is shredded, thereby increasing the dust reduction range, thereby reducing the impact of dust overflow on the human respiratory tract and improving the personal health of the staff.
[0025] Triangular plates 65 are welded to both ends of the push plate 64 on one side opposite to the electric push rod 63. The cross section of the push plate 64 is the same as the cross section of the inner cavity of the connecting square tube 61. The cross section of the protective plate 13 is larger than the cross section of the inner cavity of the connecting square tube 61. The triangular plates 65 are used to easily contact the protective plate 13, so that the protective plate 13 and the connecting square tube 61 are in an unclosed state, so that smaller materials can fall from the gap between the two sets of triangular plates 65 and the protective plate 13 into the box body 1, thereby improving the feeding efficiency of the materials.
