Detailed Description

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

Example (b): the utility model provides a counterattack breaker for building rubbish is broken, as figure 1 and figure 2, contain frame 1, be equipped with feed inlet 2 and discharge gate 3 on the frame 1 respectively, feed inlet 2 department is equipped with feeding frame 15, the slope sets firmly feeder hopper 26 communicating with feed inlet 2 on feeding frame 15, the bottom of feeder hopper 26 is equipped with sieve 16, dust collection box 17 has been placed to the below of sieve 16, the bottom of sieve 16 is connected with collection dirt cover 18, the one end that collection dirt cover 18 kept away from sieve 16 is linked together with the case mouth of dust collection box 17. Therefore, the worker can place the material to be crushed into the feeding hopper 26 and make the material fall to the feeding port 2 along the feeding hopper 26, the impact crusher can vibrate during operation to drive the feeding hopper 26 to shake, so that dust in the material in the feeding hopper 26 can be shaken off and then fall through the sieve plate 16, and the material falls into the rack 1 from the feeding port 2 along the feeding hopper 26; thereby playing the effect of reducing the dust content of the material, reducing the dust content in the material entering the rack 1, reducing the dust content in the final product and improving the qualification rate of the aggregate product. The dust falling from the sieve plate 16 can fall into the dust collection box 17 along the dust collection sleeve 18 uniformly, so that the possibility of the influence on the environment due to the diffusion of the dust at the feed port 2 is reduced.

As shown in fig. 2 and 3, a rotor frame 8 is rotatably connected in the frame 1, a board hammer 9 is arranged on the rotor frame 8, a first impact frame 4 is arranged in the frame 1, a first impact board 6 is arranged on the first impact frame 4, a plurality of second bone seams 12 which correspond to each other and are communicated with each other are respectively arranged on the first impact frame 4 and the first impact board 6, and the size of the second bone seams 12 is set as: material of a size required for one-time crushing can pass through the second bone material slot 12. Therefore, the material falling from the feeding hole 2 of the frame 1 can be crushed under the impact of the plate hammer 9 and then thrown to the first impact plate 6 for crushing again, after repeated crushing, a part of the material meeting the requirement of one-time crushing can fall from the gap between the plate hammer 9 and the first impact frame 4, and the other part of the material can pass through the second bone material gap 12 under the driving of the plate hammer 9. The second aggregate seam 12 reduces the possibility that part of materials with the sizes meeting the requirements continuously impact on the first impact plate 6 under the driving of the plate hammer 9 and are difficult to fall from the gap between the plate hammer 9 and the first impact frame 4, so that the materials impact back and forth between the plate hammer 9 and the first impact plate 6 to cause multiple times of crushing and crushing, thereby reducing the dust content in the product and improving the qualification rate of the aggregate product.

As shown in fig. 2 and 4, a second impact frame 5 is arranged in the frame 1, a second impact plate 7 is arranged on the second impact frame 5, a plurality of first framework seams 10 which correspond to each other and are communicated are respectively arranged on the second impact frame 5 and the second impact plate 7, a blocking plate 13 is fixedly arranged on the frame 1 above the second impact frame 5, and the size of the first framework seams 10 is set as: material of a desired size may pass through the first material seam 10. Therefore, part of the materials flying out of the second bone material seam 12 can directly hit the second impact plate 7, part of the materials flying to the upper part of the second impact frame 5 can be blocked by the blocking plate 13, then the materials fall between the plate hammer 9 and the second impact plate 7, the materials falling from the gap between the plate hammer 9 and the first impact frame 4 are crushed again under the impact of the plate hammer 9 and the second impact plate 7, at the moment, the materials which meet the required granularity after crushing directly fall from the discharge port 3, and part of the materials fly out of the first bone material seam 10. The first aggregate seam 10 reduces the possibility that part of materials which accord with the required particle size repeatedly impact on the second impact plate 7 under the driving of the plate hammer 9 and are difficult to fall from the discharge port 3, so that the materials are crushed for multiple times, the dust content in the product is further reduced, and the qualification rate of the aggregate product is improved.

As shown in fig. 2, a material receiving plate 11 is fixedly arranged between the second counterattack frame 5 and the frame 1, and one end of the material receiving plate 11 facing the discharge port 3 is communicated with the discharge port 3. Therefore, the materials flying out from the first material seam 10 can fall onto the material receiving plate 11 after impacting on the frame 1, and then fall uniformly along the material receiving plate 11 to the material outlet 3. The rack 1 is provided with a support plate 14 in a tilted and fixed mode, one end, far away from the rack 1, of the support plate 14 is fixedly connected with the blocking plate 13, and the support plate 14 is located on the end face, far away from the first aggregate seam 10, of the blocking plate 13. The supporting plate 14 plays a role in supporting the blocking plate 13, and reduces the possibility that materials flying out from the first aggregate seam 10 directly impact on the blocking plate 13 for a long time, so that the blocking plate 13 deforms and topples backwards under the impact of the materials, the blocking effect on the materials is lost, partial materials pass through the second impact frame 5, directly fall onto the material receiving plate 11, and uniformly fall onto the discharge port 3 along with the material receiving plate 11, and the qualified rate of aggregate products is reduced.
