Description

A new type of crusher roller

technical field

The utility model belongs to the technical field of crushing mechanical equipment components, in particular to a new pair of crushing rollers.

Background technique

Crushing devices are widely used in industry and life at present, and there are many kinds of crushing devices. At present, all kinds of crushing devices generally adopt the principle of rolling and crushing between the movable rotor and the stator and rotor to achieve crushing. Broken, at present, most of the rollers of the roller crusher are crushed by smooth roller extrusion. This method of roller crushing has the disadvantage that the crushing area of the rollers with the same diameter is small, and the smooth roller The particle shape of the crushed products is irregular, and there are many defective products. To solve this problem, the applicant once filed a patent application for the ring tooth design (2016202720209). This application is more advanced than the previous smooth round roller, but the design of this type Feeding and feeding efficiency is relatively poor.

Utility model content

The technical task of the utility model is to provide a new type of crusher pair of rollers for the above deficiencies in the prior art.

The technical solution adopted by the utility model to solve the technical problem is a new pair of crusher rollers, including a roller body and a ring tooth layer. The roller body is cylindrical and has a transparent shaft hole in the middle of the cylinder, and The ring-shaped ring tooth layer is fixed on the roller body by bolts, and the outer surface of the ring tooth layer is provided with ring teeth made of wear-resistant materials. There are gaps on the ring teeth, and two adjacent gaps A tooth block is formed therebetween, and the tooth block of one ring tooth in the two adjacent ring teeth is adjacent to the notch of the other ring tooth.

Further preferably, the tangential shape of the tooth block is trapezoidal.

Furthermore, it is installed in the way that the ring teeth of the pair of rollers are engaged with each other, and the engagement distance between the ring teeth is 2-10cm, so that the producer can adjust the distance between the ring teeth according to the demand to obtain the required products of different specifications.

This is the beneficial effect of utility model is:

1. Reasonable design, simple structure, convenient installation and maintenance;

2. The design of double roller ring teeth effectively increases the crushing area, effectively improves the crushing efficiency of the crusher, and the grain shape of the products crushed by the double roller ring teeth is regular;

3. At the same time, the segmented design of the ring teeth, that is, the design of the tooth block and the gap, increases the efficiency of feeding, thereby effectively improving the crushing efficiency.

detailed description

With reference to the accompanying drawings of the description, the work flow of the present utility model is described in detail below:

As shown in Fig. 1, Fig. 2 and Fig. 3, a new pair of crusher rollers includes a roller body 1 and a ring tooth layer 2. The roller body 1 is cylindrical and has a transparent shaft hole in the middle of the cylinder. 5, and the annular ring tooth layer 2 is fixed on the roller body 1 by bolts, the outer surface of the ring tooth layer 2 is provided with ring teeth 3 made of wear-resistant materials, and the ring teeth 3 are arranged at intervals There is a notch 4 , and a tooth block 6 is formed between two adjacent notches 4 , and the tooth block 6 of one ring tooth 3 of the two adjacent ring teeth 3 is adjacent to the notch 4 of the other ring tooth 3 .

Further preferably, the sectional shape of the tooth block 6 is trapezoidal.

Claims (2)

1. new type crushing machine is to a roller, and including roll body (1) and ring tooth layer (2), described roll body (1) is cylindric and described cylinder Centre has penetrating axis hole (5), and circular ring tooth layer (2) is bolted on roll body (1), described ring tooth layer (2) outer surface is provided with the ring tooth (3) being made up of high-abrasive material, it is characterised in that: it is interval with breach on described ring tooth (3) (4), tooth block (6), and the tooth block (6) of a ring tooth (3) in adjacent two ring teeth (3) are formed between adjacent two breach (4) Adjacent with the breach (4) of another ring tooth (3).

A kind of new type crushing machine the most according to claim 1 is to roller, it is characterised in that: the tangent plane shape that described tooth block (6) is Shape is trapezoidal.
