Abstract

The invention discloses a material pushing device at the material feeding position of a crusher, aiming at providing a material pushing device which can ensure the production efficiency of the crusher to be sufficiently exerted by effectively pushing the material bonded on the chamber wall of the inlet passage into the material inlet chamber; the material pushing device comprises a pushing head (20) which is arranged in the material inlet passage (11) and at one side of the opposite chamber wall of the inlet of a crushing chamber (12), a driving device which is rotatablely connected with the pushing head (20) and drives the pushing head (20) to linearly reciprocate along the chamber wall, and a guiding device which restrains the moving direction of the pushing head (20). The material pushing device effectively solves the technical difficult problem that the crushing productivity of material containing water and soft shale which disturbs people for a long time is low and can be widely applied to the improvement of various hammer-typed crushers or reverse-impact typed crushers.

Description

Pusher mechanism at feeding site of crusher

Technical field

The present invention relates to disintegrating machine,, the material that particularly a kind of energy that is used on hammer mill or the impact breaker will be attached on the feeding-passage place pushes working chamber and carries out broken material-pulling device.

Background technology

Hammer mill and impact breaker mainly are applicable at the broken medium-hard material of industrial departments such as cement, brickmaking, chemical industry, electric power, metallurgy, as operation broken and in small, broken bits in the materials such as lime stone, slag, coke, coal, shale, gangue.Existing hammer mill mainly is made up of crusher chamber and the parts such as hammering assembly that are installed in it, and the top of crusher chamber communicates with feeding-passage, and its underpart arc section is made of sieve plate.During work, the hammering assembly that has a plurality of tups through the transmission mechanism driven rotary, will enter material hammering fragmentation in the crusher chamber by motor by feeding-passage, and the material that reaches the regulation fineness drops out crusher chamber through sieve plate under gravity and/or compressed-air actuated effect.

In the shattering process, the partial material under the effect of rotation tup in the crusher chamber can be spattered to feeding-passage and the relative chamber wall of crusher chamber inlet.After these materials and the feeding-passage chamber wall collision under normal circumstances, can be in crusher chamber be fallen back in the effect of self gravitation.If but material contains moisture content, then part expects that thing can be attached on the wall of feeding-passage chamber, and effective charging area of feeding-passage is reduced, and causes the production efficiency of disintegrating machine to reduce significantly.This phenomenon is the most serious when soft shale is carried out fragmentation, even can stop up feeding-passage, and disintegrating machine can't be worked on.This problem is never effectively solved for a long time.

Summary of the invention

Technical problem to be solved by this invention provides a kind of pusher mechanism at feeding site of crusher, and this device can push feed cavity with the material that is attached on the wall of feeding-passage chamber effectively, therefore can guarantee that the production efficiency of disintegrating machine is not fully exerted.

The technical solution adopted for the present invention to solve the technical problems is: pusher mechanism at feeding site of crusher of the present invention, it is characterized in that: this material-pulling device comprises and being arranged in the feeding-passage and crusher chamber the cutting somebody's hair of relative chamber wall one side that enter the mouth, be in transmission connection and drive the drive unit that it moves along this chamber wall linear reciprocation with cutting somebody's hair, and the cut somebody's hair guider of moving direction of constraint.

Described drive unit comprises motor and speed reducer, and the slider-crank mechanism that makes speed reducer output shaft, cuts somebody's hair and be in transmission connection.

Described slider-crank mechanism respectively is provided with one group at the two ends of speed reducer output shaft.

The invention has the beneficial effects as follows, owing to can remove the material that is attached on the wall of feeding-passage chamber effectively in the crushing operation process, and with in its propelling crusher chamber, therefore can guarantee the production efficiency of disintegrating machine, thereby solved effectively and perplexed the broken productivity ratio of people's water-containing materials, soft shale for a long time always and fall this technical barrier, can be widely used in the improvement of various hammer mills or impact breaker.

Parts, toponym and pairing mark among the figure: feeding-passage 11, crusher chamber 12, guide plate 13, guide rail 14, cut somebody's hair 20, connecting rod 21, roller 22, motor 30, reductor 31, end cap 32, eccentric pin shaft 33.

The specific embodiment

The present invention is further described below in conjunction with drawings and Examples.

With reference to Fig. 1 and Fig. 3, pusher mechanism at feeding site of crusher of the present invention comprises being arranged in the feeding-passage 11 with crusher chamber 12 enters the mouth relative chamber wall one side cuts somebody's

hair

20,20 be in transmission connection and drive the drive unit that it moves along this chamber wall linear reciprocation with cutting somebody's hair, and the cut somebody's hair guider of 20 moving directions of constraint.In the shattering process, cut somebody's hair and 20 move repeatedly along the chamber wall, remove the material that is attached on the wall of chamber, and it is pushed back in the crusher chamber 12, therefore can guarantee the production efficiency of disintegrating machine, thereby solved effectively and perplexed the broken productivity ratio of people's water-containing materials, soft shale for a long time always and fall this technical barrier, can be widely used in the improvement of various hammer mills or impact breaker.

Obviously, drive unit can adopt multiple version, as electric pushrod, hydraulic mechanism etc.By the embodiment 1 shown in Fig. 1, Fig. 2 with in by the embodiment 2 shown in Fig. 3, Fig. 4, all adopt with the simplest and compact drive unit of a kind of structure, be that described drive unit comprises motor 30 and reductor 31, and make reductor 31 output shafts, 20 slider-crank mechanisms that are in transmission connection of cutting somebody's hair.With reference to Fig. 2 and Fig. 4,20 move steadily for making to cut somebody's hair, described slider-crank mechanism respectively is provided with one group at the two ends of reductor 31 output shafts.With reference to Fig. 1 and Fig. 3, described slider-crank mechanism 20 is made of with cutting somebody's hair end cap 32, connecting rod 21, and end cap 32 is fixed on the axle head of reductor 31 output shafts, an end of connecting rod 21 with cut somebody's hair 20 hingedly, the other end is then hinged by eccentric pin shaft 33 and end cap 32.
