1. The novel material storage box comprises a box body, 2 vertical rods, 3 supporting plates, 4 connecting shafts, 5 cross rods, 6 crushing teeth, 7 rotating shafts, 8 chain wheels, 9 chains, 10 motors, 11 transverse plates, 12 sleeves, 13 lifting rods, 14 springs, 15 guide rails, 16 sliding blocks, 17 straight rods, 18 pulleys, 19 supporting rods, 20 inclined rods, 21 rear baffle plates, 22 material plates, 23 material bins, 24 blanking ports, 25 damping blocks, 26 material inlets, 27 material outlets, 28 lock catches, 29 lock noses and 30 stop doors.

Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings 1 to 7.

The utility model can repeatedly hammer materials until the crushing effect is expected, the crushed materials can leak from the blanking port 24, then the matching between the lock nose 29 and the lock catch 28 at the material outlet 27 can be released to open the stop door 30, the crushed materials are taken out, and the lock nose 29 and the lock catch 28 are the prior art and the structure thereof is not described in detail. When using this device, to the shutter 30 of opening material import 26 department, later drive the chain 9 through starter motor 10 and rotate, and then drive hoisting device promotes breaker to be higher than material board 22 and box 1 inner wall and backplate 21 and surround the suitable position that forms material storehouse 23, then stop motor 10 from material export 27 add the needs broken material such as ore, coal cinder, the height is favorable to the material equipartition on material board 22 around material board 22. Then close upside shutter 30, start motor 10, motor 10 drives the pivot 7 rotation of upside, upside pivot 7 rotates and will make the pivot 7 and two sprockets 8 and the synchronous rotation of chain 9 of downside, chain 9 rotates will drive diaphragm 11 and with diaphragm 11 fixed connection's sleeve 12 rebound, lifting rod 13 in the sleeve 12 will also drive through connecting axle 4 with 3 fixed connection's montant 2 rebound simultaneously, and the breaker will wholly vertical rebound under the sliding fit restriction of slider 16 and guide rail 15. As the chain 9 continues to rotate, the pulley 18 on the straight rod 17 fixedly connected with the lifting rod 13 is in contact with the inclined rod 20, the inclined rod 20 fixedly connected with the supporting rod 19 is of a structure with a low front part and a high back part, so that the inclined rod 20 and the pulley 18 generate a relative action, the lifting rod 13 is forced to slide towards the sleeve 12 through the straight rod 17 and compress the spring 14, the lifting rod 13 moves towards the sleeve 12 to gradually separate the lifting rod 13 from the matching with the connecting shaft 4, the connecting shaft 4 loses support, namely the crushing device loses support, at the moment, due to the limitation of the sliding matching of the guide rail 15 and the sliding block 16, after the connecting shaft 4 loses support, the crushing device vertically falls along the guide rail 15, and the crushing teeth 6 below the cross rod 5 hammer and crush the material on the material plate 22. As the chain 9 continues to rotate, the pulley 18 disengages from the diagonal rod 20, at which point the spring 14 will extend itself and drive the lifting rod 13 to slide out of the sleeve 12, and then as the chain 9 continues to rotate the lifting rod 13 will again engage with the connecting shaft 4 and drive the crushing device to move upwards again and repeat the above process, which achieves repeated hammering of the material by the crushing device.

The shock absorption block 25 is arranged to reduce the impact of the crushing device when the empty machine runs for some reasons. The dust can be avoided to inclosed box 1, and the setting of shutter 30 can be convenient for getting of material and put.
