Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shredders, in particular to a double-shaft shredder. Background Art
[0002] As we all know, the double-shaft shredder is also known as the shear-type shredder. The principle is that staggered blades are installed on the two cutter shafts. The two cutter shafts reduce the size of the material by shearing the blades and tearing the teeth during the process of rotating towards each other. The main shearing method is the shearing effect of the adjacent moving knife edges, and the secondary shearing method is the tearing effect of the moving knife teeth.
[0003] Double-shaft shredders are widely used in industrial waste, domestic waste, municipal waste, garden waste, medical waste, kitchen waste, biomass crushing and other fields to achieve the purpose of waste volume reduction, recycling, and thus beautifying the urban environment and improving the quality of people's living environment.
[0004] When the existing double-shaft shredder is in use, the feeding end is mostly an open structure. Although this feeding method is simple, it will have certain safety hazards and may easily cause the shredder to accidentally injure the staff, and has low practicality. Utility Model Content

DETAILED DESCRIPTION
[0019] 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.
[0020] See also Figure 1-3The utility model discloses a double-shaft shredder, comprising a double-shaft shredder body 1, wherein the upper end of the double-shaft shredder body 1 is provided with a box body 2 and a placement box 9, wherein an empty slot 5 is arranged inside the box body 2, and the empty slot 5 is located above the double-shaft shredder body 1, and a plurality of limit blocks 6 are symmetrically arranged on the inner wall of the empty slot 5, and a plurality of limit slots 13 are symmetrically arranged on the outer wall of the placement box 9, and the limit blocks 6 cooperate with the limit slots 13, and a placement slot 8 is arranged inside the placement box 9, and two slide slots 10 are symmetrically arranged at the bottom of the placement slot 8, and a bottom plate 11 is arranged at the bottom end of the placement box 9, and two sliders are symmetrically arranged on both sides of the bottom plate 11, and the sliders cooperate with the slide slots 10, and the front ends of the placement box 9 and the bottom plate 11 are both provided with handles. When the structure is in use, the placement box 9 is first pulled out of the empty slot 5, and because there is a certain friction between the slider and the slide slot 10, the position of the bottom plate 11 is fixed at the bottom of the placement slot 8. The material to be shredded is then placed in the placement slot 8, and the placement box 9 is pushed to reset the placement box 9 inside the empty slot 5. Then, the placement box 9 is pressed to provide a pulling force to the bottom plate 11, and the bottom plate 11 is pulled out at the bottom of the placement slot 8. At this time, the material in the placement slot 8 will fall into the inside of the double-shaft shredder body 1. In this process, the limit block 6 and the limit slot 13 cooperate with each other, which can provide a guiding effect for the placement box 9 in the empty slot 5, so that the placement box 9 is smoother when being pulled out, and the bottom plate 11 can be provided with a guiding effect at the bottom of the placement slot 8 by the mutual cooperation of the slider and the slide slot 10, so that the bottom plate 11 is smoother when being pulled out. When loading materials, the human hand will not be located directly above the double-shaft shredder body 1, and through the provided box body 2, the feeding end of the double-shaft shredder body 1 is no longer an open structure, which reduces the safety hazard of this structure when in use, prevents the shredder from accidentally injuring the staff, and has high practicality.
[0021] If the friction between the material and the placement slot 8 is too large, it is not convenient to unload the material in the placement slot 8. A lifter 3 is provided at the top of the box body 2, and a lifting plate 15 is provided at the bottom of the empty slot 5. The output end of the lifter 3 is provided with a lifting rod that penetrates the box body 2 and is connected to the lifting plate 15. When the placement box 9 is located inside the empty slot 5, the lifter 3 is started, and the lifting plate 15 descends. At this time, the lifting plate 15 will provide a thrust to the material in the placement slot 8, so that the material in the placement slot 8 is easy to unload.
[0022] The lack of a guide structure between the lifting plate 15 and the box body 2 will make the lifting plate 15 unstable when being lifted or lowered. A plurality of telescopic rods 4 are provided at the upper end of the box body 2. The bottom ends of the telescopic rods 4 penetrate the box body 2 and are connected to the upper end of the lifting plate 15. When the lifting plate 15 is lifted or lowered, the telescopic rods 4 will be extended or retracted. By providing a plurality of telescopic rods 4, a guide structure can be provided between the lifting plate 15 and the box body 2, making the lifting plate 15 more stable when being lifted or lowered.
[0023] The lack of a positioning structure between the placement box 9 and the box body 2 will affect the stability of the placement box 9 when it is placed. Two side panels 12 are symmetrically arranged at the front end of the placement box 9, and a positioning block 14 is arranged on the side panel 12. Two positioning grooves 7 are symmetrically arranged at the front end of the box body 2. The positioning block 14 is inserted into the interior of the positioning groove 7. When the placement box 9 is located in the empty groove 5, the positioning block 14 will be inserted into the interior of the positioning groove 7, and there is a certain friction between the positioning block 14 and the positioning groove 7. Through the mutual cooperation between the positioning block 14 and the positioning groove 7, a positioning structure can be provided between the placement box 9 and the box body 2, thereby improving the stability of the placement box 9 when it is placed.
[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
