Description

Crusher appearance anti-bridging structure

Technical Field

The utility model relates to a breaker technical field, its concretely relates to structure of taking a bridge is prevented to breaker appearance.

Background

At present, crushing machines are suitable for crushing various materials which are brittle, medium hard and have low water content. The material blocking device is widely used in building material, metallurgy, chemical industry and thermal power generation industry, but has the problems of blocking a hammer head screen bar caused by bonding, bridging and material blocking of large-space materials in structure. The breaker is at broken material upset in-process, because the big broken back of material moisture, the granule is thin, easily forms the bridge in broken chamber the inside, and the accumulational condition then leads to the unable continuation operation of breaker putty. In summary, the equipment is better used and the change of the water content of the materials in the field environment is adapted, and the materials contain viscous materials. To this end, we propose a new crusher outer shape.

SUMMERY OF THE UTILITY MODEL

The utility model provides a novel crushing machine is applicable to broken fragility, well hard, and various materials that the water content is less realize mechanized broken system appearance in minerals such as building materials, metallurgy, chemical industry, thermal power industry, mainly used broken coal, gangue, sandstone, shale, lime stone, gypsum, and the crushing machine has characteristics such as steady operation, reliable, long service life, compact structure, the dust is few, the noise is low, not pile up the material.

In order to solve the above problems, the utility model adopts the following technical proposal:

a crusher form anti-bridging structure comprising: the hammer comprises an upper shell and a lower shell, wherein the upper shell and the lower shell are fixedly connected in a critical manner, a driving shaft is arranged at the critical position of the upper shell and the lower shell, and a hammer rotor is arranged on the driving shaft;

the upper housing includes: the crushing device comprises a right-angle part and an integrally formed arc-shaped part, wherein the arc-shaped part and the right-angle part form a reduced irregular material crushing cavity;

the upper half part of the hammer head rotor is located in an irregular material crushing cavity, and the rotating direction of the hammer head rotor is tangent to the material entering direction and the arc-shaped part.

As an improvement of the above technical solution, the arc portion includes: along broken arc panel and the slope panel of material entering direction, broken arc panel with slope panel integrated into one piece and smooth transition connect.

As an improvement of the technical scheme, the crushing arc-shaped panel, the inclined panel and the right-angle part form a reduced irregular material crushing cavity, and the rotating direction of the hammer head rotor is tangent to the material entering direction and the crushing arc-shaped panel.

As the improvement of the technical scheme, three crushing hammers are arranged on the front surface and the back surface of the hammer rotor in equal radian, and the crushing hammers arranged on the front surface and the back surface of the hammer rotor are arranged in a staggered manner.

Compared with the prior art, the utility model discloses an implement the effect as follows:

(1) the appearance structure is compact and the space is saved.

(2) The angle that the material passes through the feed inlet concentrates the breaker tup department of falling, improves crushing efficiency.

(3) The outer wall arc structure avoids the waste of efficiency caused by the back-and-forth turnover of redundant materials.

Detailed Description

The present invention will be described with reference to specific embodiments.

As shown in fig. 1: a crusher form anti-bridging structure comprising: the hammer comprises an upper shell 1 and a lower shell 2, wherein the upper shell 1 is fixedly connected with the lower shell 2 in a critical manner, a driving shaft 3 is arranged at the critical position of the upper shell 1 and the lower shell 2 (the driving shaft 3 is provided with driving force by a corresponding motor or other power sources), and a hammer rotor 4 is arranged on the driving shaft 3; wherein the upper housing 1 again comprises: a right-angled portion 11 and an integrally formed arcuate portion, the arcuate portion comprising: along the broken cambered surface board 121 and the inclined plane 122 of material entering direction, its broken cambered surface board 121 and inclined plane 122 integrated into one piece and smooth transition connect, broken cambered surface board 121, inclined plane 122, and right angle portion 11 constitute the irregular material crushing chamber 13 that dwindles. Wherein, the first half of tup rotor 4 is located irregular material crushing chamber 13, and the direction of rotation of tup rotor 4 all is tangent with material entering direction and arc part. The utility model discloses a through changing the broken chamber outer wall shape of breaker, reduce unnecessary working space and let the tup breakage more accurate, effectual improvement crushing performance. The method specifically comprises the following steps: the material is along direction and angle in fig. 1, just in time through the broken tangent line of broken tup 41, carries out the breakage with the material more fully, when unnecessary material fails broken, because the limited material that makes in clearance between broken arc panel 121 and broken tup 41 can not be because of the tup high-speed operation is thrown up, influences crushing efficiency and feeds into once more and forms and piles up, the bridging condition.

Specifically, three crushing hammers 41 are arranged on the front surface and the back surface of the hammer rotor 4 in equal radian, the crushing hammers 41 arranged on the front surface and the back surface of the hammer rotor 4 are arranged in a staggered mode, the crushing hammers 41 are in a tangential contact state with the material entering direction, the crushing hammer is mainly used for crushing the material, and the crushing efficiency is very high.

The utility model aims at providing a breaker is at broken material in-process, runs into the material water content and is slightly higher to and follow-up always feeding, thereby remaining material continues the upset in the breaker and causes broken intracavity portion material overlap joint and jam to appear, and unable normal operating's phenomenon carries out the solution of pertinence to this, on the putty basis of solving the site environment material, has improved the crushing efficiency of breaker simultaneously, has further improved the feasibility of the smooth and easy operation of breaker in operating system.

The foregoing is a detailed description of the invention in connection with specific embodiments thereof, and it is not intended that the invention be limited to these specific embodiments. To the utility model belongs to the technical field of technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses the scope of protection.
