The utility model is realized by the following technical means:
the double-roller shredder with the double-layer box structure comprises a double-layer box body arranged on a rack, wherein the double-layer box body consists of an inner shell, an outer shell and a connecting plate; the inner shell is internally provided with a shredding roller, the shredding roller is arranged on a rotating shaft, the rotating shaft is fixedly arranged through rotating shaft seats arranged on two sides of the outer shell, the rotating shaft seats are fixed on the outer shell, and the rotating shaft is fixedly arranged through a pair of rotating shaft seats; the feeding hopper is arranged above the double-layer box body, and the lower opening of the feeding hopper is connected with the inner shell;
further, two sets of shredding rolls are arranged in the inner shell;
further, the shredding roll and the rotating shaft have concentric axes;
further, a mesh enclosure is arranged outside the shredding roller;
further, the space that forms between the inner shell with the shell is for leaking the ash groove, leak the ash groove and can collect the hard piece or the granule that tear up waste material and old and useless material and produce, avoid hard piece or granule is to the damage or block rotatory pivot, causes the speed reduction, shut down or to the inner shell with the damage deformation of shell.
Further, the rotating shaft seat is fixed on the shell through a plurality of symmetrically distributed screws;
the double-layer box body structure of the double-roller shredder is characterized in that a dust leakage groove is formed in a space between the inner shell and the outer shell, hard fragments or particles of shredded materials extruded by a gap between the rotating shaft and the inner shell are collected in the dust leakage groove in the material crushing process, an opening and a sealing plate can be arranged at the bottom or the side wall of the outer shell, when a storage object in the dust leakage groove needs to be cleaned, the sealing plate can be opened, and the stored hard fragments or particles are cleaned out from the dust leakage groove by a high-pressure water gun or a high-pressure air gun, so that the double-roller shredder can work normally.
The ash leakage groove is used for accommodating material fragments formed in the shredding operation, particularly hard fragments or particles, so as to prevent the double-roller shredder from being blocked in the shredding operation, and protect the rotating shaft from being damaged by the hard fragments or particles of the materials and from being damaged by gnawing; since the spindle is rotating and the other parts are stationary, during the actual shredding operation the hard chips or particles will be forced into the ash chute through the gap between the spindle and the inner shell and accumulated.
In the double-layer box structure double-roller shredder, in actual use, the material fragments and particles accumulated in the ash leakage groove can be cleaned by a high-pressure air gun or a high-pressure water gun so as to maintain the normal operation and use of the double-layer box structure double-roller shredder.
The utility model has the beneficial effects that:
by improving the structure of the double-roller shredder, material fragments, particularly hard fragments or particles, formed in the shredding operation can be effectively collected in the ash leakage groove, so that the double-roller shredder is prevented from being clamped in the shredding operation, and the rotating shaft is prevented from being damaged by the hard fragments or particles of the material and the damage effect of biting; simultaneously, avoid shredding the operation and because the box deformation that the pivot was blocked and arouses, ash leakage groove can conveniently use high-pressure air gun or squirt clearance effectively.
In order to make the objects and technical solutions of the embodiments of the present utility model more clear, the technical solutions of the embodiments of the present utility model will be clearly and completely described below in conjunction with examples of embodiments of the present utility model.
