Abstract

The utility model provides an efficient fine crusher hammer head which comprises a hammer had and a hammer handle connected with each other; through holes are arranged on the hammer head and the hammer handle, concave grooves are arranged on both ends of the through hole of the hammer head, a lug boss is arranged on the through hole of the fitting surface of the hammer handle and the hammer head, and the other end of the hammer handle is provided with a concave groove. The efficient fine crusher hammer head has the technical effects that: 1. the hammer head can be used for 4 times in turnover manner, and the current hammer head only can be used twice in turnover manner, so the service life of the hammer head in the same weight is doubled, and the material utilization rate is greatly improved; 2. the hammer head is fixed by ellipse bolts, compared with the hammer head fixed by thread tapping, the casting defect seldom occurs, the fine crusher is ensured to operate reliably for long time, and the use cost of the fine crusher is also reduced.

Description

Efficient fine crusher tup

Technical field

The utility model relates to a kind of tup, specifically, relates to a kind of efficient fine crusher tup.

Background technology

Fine crusher is mainly used in the various materials of broken fragility, middle hardness, this equipment is widely used in industries such as chemical industry, building materials, metallurgy, mining, coal separation, system sand and refractory material, hardness material in lime stone, clinker, iron ore, shale, dolomite, granite, gypsum, the composite material etc. is carried out efficiently in small, broken bits, be specially adapted to the in small, broken bits of lime stone and grog.

In use there are many problems in fine crusher at present, mainly is that service life is very short, often will change because the tup of fine crusher is big owing to use amount; All there is the very low shortcoming of hammer head material utilization rate in the structure that structure that the tup tapping is fixing and monolateral bolt are locked, particularly easily there is casting defect in the fixing structure of tup tapping, equipment fault easily taking place during use, increase maintenance cost, influences the long-term safety operation of equipment.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of with low cost and efficient fine crusher tup that can use for a long time is provided.

Efficient fine crusher tup of the present utility model comprises tup and hammer handle, and both link to each other, be equipped with through hole on said tup and the hammer handle, the two ends of the through hole of tup are provided with groove, and the through hole on hammer handle and the tup mating surface is provided with boss, and the other end of hammer handle is provided with groove.

Preferably,

Said groove is elliptic cone, links to each other by oval bolt between tup and the hammer handle.

Efficient fine crusher tup of the present utility model has following technique effect:

1, the turning use of tup of the present utility model is 4 times, and existing tup can only overturn and use 2 times, and therefore, the tup of same weight has increased nearly 1 times service life, and the material utilization rate is greatly improved;

2, tup of the present utility model adopts oval bolt to fix, and compares with the tup that tapping is fixing, casting defect seldom takes place, thereby the equipment that guaranteed moves reliably and with long-term, has reduced the equipment use cost.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is the structural representation of the efficient fine crusher tup of the utility model;

Fig. 2 is the tup work schematic diagram of the efficient fine crusher tup of the utility model;

Fig. 3 is the hammer handle structural representation of the efficient fine crusher tup of the utility model.

Wherein, 1 is that tup, 2 is that oval bolt, 3 is hammer handle, and 4 is through hole, and 5 is groove, and 6 is boss.

The specific embodiment

As Fig. 1, shown in Figure 3, efficient fine crusher tup of the present utility model, comprise tup 1 and hammer handle 3, and both link to each other, be equipped with through hole 4 on tup 1 and the hammer handle 3, the two ends of the through hole 4 of tup 1 are provided with groove 5, and through hole 4 places on hammer handle 3 and tup 1 mating surface are provided with square boss 6, and the other end of hammer handle 3 is provided with groove 5.Grooves 5 all on tup 1 and the hammer handle 3 are elliptic cone, link to each other by oval bolt 2 between tup 1 and the hammer handle 3.

As shown in Figure 2, tup 1 of the present utility model is when work, and material enters in the fine crusher from the top material inlet, the motor drives rotor is rotation at a high speed in crusher chamber, epitrochanterian tup carries out high-speed motion, and strike, impact, shearing, grinding material make its fragmentation.Tup uses for turning 4 times, and upset uses a, b, c, d limit to carry out fragmentation successively.

Claims

1. efficient fine crusher tup comprise tup and hammer handle, and both links to each other, it is characterized in that be equipped with through hole on said tup and the hammer handle, the two ends of tup through hole are provided with groove, through hole on hammer handle and the tup mating surface is provided with boss, and the other end of hammer handle is provided with groove.

2. efficient fine crusher tup according to claim 1 is characterized in that said groove is elliptic cone, links to each other by oval bolt between tup and the hammer handle.
