Extend to and throw on screw-conveyer-shaft in case 28 equipped with throwing blade 29；Pass through mounting bracket in the frame 1 of the broken side of cylinder 17 of second patent flour
Equipped with the broken motor 16 of second patent flour, the broken motor 16 of second patent flour with power transmission shaft 21 and transmits the screw-conveyer-shaft of auger 19 respectively by driving-chain
Connection.One-level reducing mechanism is crossed to be connected communicating pipe 30 with the charging aperture of the broken cylinder of second patent flour 17.
When there is the pulverizer of multi-stage crushing function to work for this, material to be comminuted conveyer belt 3, on feeding roller 9 and under
Enter under the cooperation of feeding roller 10 between upper precompressed breaker roll 4 and lower precompressed breaker roll 5.By upper precompressed breaker roll 4 and lower pre-
The precompressed of pressure breaker roll 5 is broken enter to rub roller 12 and under rub between roller 13.Due to above rub roller 12 and under rub roller
Transmission process between 13, is to rub roller 12 by down to be connected with above rubbing roller 13 by speed change reverse wheel.Therefore roller 12 is rubbed on
Roller 13 is rubbed with and has certain speed discrepancy in rotation process, and this speed discrepancy is convertible into and treats rubbing for comminuting matter
Rub power with the hands, by the kneading force the broken material of precompressed can be made more to crush；To increase the rapidity and completeness subsequently crushed, and
Improve and crush quality.Complete the precompressed size-reduced hobboing cutter 6 of material and crushing stationary knife 7 broken and rub to crush, the material after crushing
Naturally drop in communicating pipe 30, hence into in the broken cylinder 17 of second patent flour.In the broken cylinder 17 of second patent flour, the material after crushing exists
Rotated in the presence of impeller 23 in the broken cylinder 17 of second patent flour, during this, material is constantly touched with the cutter tooth 27 on cutter tooth plate 26
Hit, so as to be crushed again, when crushing material when designing particle diameter by sieve plate 25 to entering in transfer drum 18, then pass through transmission
Auger 19, which enters, throws case 28, collects, thus completes eventually through throwing blade 29 and throwing cylinder 20 to be thrown to designated area
The whole crushing process of material to be comminuted.
The mill structure is simple, and the selectivity to comminuting matter is small, and the material disposably crushed can meet and make plate and warp
The requirement of Ji crop-planting.Existing pulverizer is solved due to reasons in structure, the material particles disposably crushed are spent greatly, work
Less efficient, production cost and cost of labor are too high, and larger to the selectivity of comminuting matter, and with certain toughness, soft
The problem of power transmission shaft is easily twined dead by the material of softness, with positive dissemination.
