The large cage body and the small cage body are formed by cage bars and cage bar annular connecting components which are fixedly connected to two sides of the cage bars; the cage bars of the large cage body and the small cage body are formed by cage bar shafts and wear-resistant sleeves of the cage bar shafts; shaft heads of the cage bar shafts are provided with threads; the shaft heads with the threads are fixedly connected onto the cage bar annular connecting components of the large cage body and the small cage body via thread connecting components, the cage bar annular connecting components are equipped with installation holes; and the wear-resistant sleeves are sheathed on the cage bar shafts and capable of rotating around the cage bar shafts. The cage crusher can prolong the service life and replacement period as the wear-resistant sleeves can rotate and wearing areas are uniform; achieve convenient replacement and maintenance, decrease maintenance cost, reduce labor intensity and improve working efficiency as the cage bar shafts are detachable; and is suitable for crushing materials in industries such as brick-making and the like.

Description

Cage crusher

Technical field

The utility model relates to field of cracking machine, the cage crusher that particularly a kind of brickmaking industry is used.

Background technology

Existing cage crusher in use, big cage body is pulverized material with the counter-rotating of little cage body, the cage bar serious wear on cage body and the little cage body often needs repairing greatly.Common method for maintaining is to cage bar Repair Welding with wear resistance electrode.Because electric welding machine power consumption height, the cost of wear resistance electrode is also very high, drops into a large amount of manpowers again, and the cage bar is worn and torn, and difficulty is repaired in the back, cost is high, is that a lot of producers pulverize insoluble problem in the raw material production.

China's " Gazette of Patent for Invention " discloses the patent that name is called " high speed birotor cage crusher ", its patent No.: 97235882.X, publication number: CN 2286432Y.It is a kind of high speed disintegrator with dodge gate and liner, is convenient to cleaning, can improve service efficiency and service life.But also fail to solve cage bar quick abrasion, repair difficult problem.

Summary of the invention

The cage bar quick abrasion, the service life that have now on the cage crusher cage body lack, repair difficulty and the high weak point of cost in order to overcome, the utility model provides a kind of cage crusher, and the cage bar on its cage body is wear-resistant, long service life, detachable, easy to maintenance and cost is low.

The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:

Cage crusher is made of casing, bearing mounting, big cage axle, little cage axle, big cage drive, little cage drive, big cage body, little cage body, charging aperture and support etc.The two bearings mounting is positioned at the casing both sides, and large and small cage axle is installed in respectively on the two bearings mounting; Large and small cage drive is installed in the outer end of large and small cage axle respectively; Large and small cage body is installed in the inner of large and small cage axle respectively, and is positioned at casing.Charging aperture is positioned at casing one side, and casing, bearing mounting are installed on the support.Large and small cage body is made of cage bar and the cage bar annular connector that connects firmly in cage bar both sides.The cage bar is along the circumference uniform distribution of cage bar annular connector.The cage bar of large and small cage body is made up of cage bar axle and wear-resistant sleeve; The spindle nose of cage bar axle is threaded, and threaded spindle nose is by on the fastening cage bar annular connector that is connected in large and small cage body band installing hole of thread connector; Wear-resistant sleeve is enclosed within on the cage bar axle, can rotate around cage bar axle.

The beneficial effects of the utility model are:

1. because wear-resistant sleeve can rotate, in the broken material process, wear surface is more even, has prolonged service life and replacement cycle.When the wear-resistant sleeve serious wear need be changed, unclamp nut, take off wear-resistant sleeve, change and new can use after fastening again.Easy to maintenance, reduce maintenance cost, improved work efficiency.

2. because cage bar axle is detachable, it is convenient to change, and no longer relies on Repair Welding.Reduced the consumption of wear resistance electrode, saved the electricity charge, alleviated worker's labour intensity, reduced of the pollution of electric welding flue gas environment.
