Abstract

The utility model relates to an adjustable blade structure of a coarse crusher. A main shaft is arranged in a crushing chamber of the coarse crusher and provided with a plurality of moving blades, the inner wall of the crushing chamber is fixedly provided with a fixed blade through an adjusting bolt, the knife edge of the moving blade is opposite to the knife edge of the fixed blade, and a gap is remained between the knife edge of the moving blade and the knife edge of the fixed blade; and a knife rest is provided with a waist-shaped hole, and the moving blade is connected to the inside of the waist-shaped hole arranged on the knife rest through an adjusting bolt. Through the adjusting bolts, the positions of the moving blade and the fixed blade can be conveniently adjusted; the adjustable blade structure is flexible in use and convenient to use and maintain; and high-cost operation for replacing the whole blade assembly in the prior art is avoided. Crushing is realized through the impacting and the shearing generated between the moving blade and the fixed blade; materials automatically flow towards an outlet; and the complete machine is made of stainless steel material and is simple in structure.

Description

The adjustable blade structure of boulder crusher

Technical field

The utility model relates to the size reduction machinery field, especially the adjustable blade structure of boulder crusher.

Background technology

At present, pharmacy, chemical industry, food, etc. in the industry, coarse crushing is the corollary equipment of the broken processing preceding working procedure of micro mist, it does not receive restrictions such as material viscosity, hardness, softness and fiber, can play crushing effect preferably to any material.The operation principle of pulverizer is to utilize the cutting blade of rotation at a high speed and the gap between the ledger-plate that the collision that impacts that material carries out is repeatedly realized the grinding and processing operation.Different materials has different granularity requirements; Then need select suitable pulverizer; And the blade assembly of pulverizer of the prior art adopts stationary structure, is only limited to the pulverizing that a kind of granularity requires usually, then can only change whole blade assembly if need obtain different granularities; The long-term use of blade can produce certain wearing and tearing on the other hand, then can influence crushing effect behind the blade abrasion, because blade assembly adopts stationary structure, then need change whole group blade, wastes time and energy, and removes and installs inconvenience, and cost is high.

The utility model content

The defective that the applicant can't adjust to the blade assembly in the above-mentioned pulverizer of the prior art provides the adjustable blade structure of boulder crusher a kind of rational in infrastructure, easy to maintenance; Thereby can easily carry out the adjustment of blade; Need not to change whole group blade, reduce cost, production efficiency is high.

The technical scheme that the utility model adopted is following:

A kind of adjustable blade structure of boulder crusher; Main shaft is installed in the crushing chamber of its boulder crusher, is equipped with manyly on the said main shaft, through the adjusting bolt ledger-plate is arranged on the inwall of said crushing chamber cutting blade; The edge of a knife of said cutting blade is relative with the edge of a knife of ledger-plate, leaves the gap between the two; Have waist-shaped hole on the knife rest, said cutting blade is through in the waist-shaped hole of regulating bolt and being connected on the knife rest to be opened.

Its further technical scheme is:

Three cutting blade order series connection on main shaft are arranged successively relatively;

Said cutting blade becomes the recessed splayed in middle part;

Said cutting blade is flat blade.

The beneficial effect of the utility model is following:

The utility model can be regulated the position of cutting blade and ledger-plate easily through adjusting bolt, uses flexibly, has avoided needing in the prior art to change the expensive operation of whole blade assembly, and O&M conveniently.

The utility model utilizes the impact that produces between cutting blade and the ledger-plate, shearing and obtains to pulverize, and through the effect of rotary centrifugal force, material automatic stream exit, the whole machine using stainless steel material is made, and is simple in structure, good crushing effect.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the structural representation of the utility model cutting blade.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.

As depicted in figs. 1 and 2, the adjustable blade structure of boulder crusher is installed in the crushing chamber 8 of boulder crusher; Crushing chamber 8 is positioned at frame 1 top; Rotary type main shaft 9 is installed in the crushing chamber 8, and main shaft 9 is connected with the output shaft of motor 10 through decelerator, and crushing chamber 8 tops connect feed hopper 6; Feed hopper 6 tops are provided with regulates mouth 7, the inlet amount of control material; The angle of feed hopper 6 bottoms stretches to the middle part that is connected cavity of feed hopper 6 and crushing chamber 8, and its purpose is: prevent material in crushing process, because cutting blade 5 action of inertia are got rid of material and are back in the feed hopper 6; Crushing chamber 8 bottoms connect discharging opening 2, and discharging opening 2 is obliquely installed in the bottom of crushing chamber 8, makes things convenient for the material discharging; Being equipped with on the main shaft 9 that order series connection arranges successively relatively three cutting blade 5, splayeds that 5 one-tenths middle parts of cutting blade are recessed into, and be connected in the waist-shaped hole set on the knife rest 13 through adjusting bolt 12 are seen Fig. 3; On crushing chamber 8 inwalls ledger-plate 3 is installed, ledger-plate 3 is regulated bolt 4 and is fixed on the internal face of crushing chamber 8, and the blade 11 of cutting blade and the blade of ledger-plate 3 are installed relatively, leaves the gap between the two.East blade 5 also can adopt flat blade structure.

In the practical work process, first starter motor 10 is packed the material that needs are pulverized into from the adjusting mouth 7 of feed hopper 6, and material drops downwards from feed hopper 6 and gets in the crushing chamber 8; Close the adjusting mouth 7 of feed hopper 6; Motor 10 drives main shaft 9 rotations through reductor, thereby main shaft 9 rotations drive cutting blade 5 rotations, make material be involved in the gap between cutting blade 5 and the ledger-plate 3; And impacted, shear acquisition by atwirl blade and pulverize; The pulverizing that material is repeatedly circulated in crushing chamber 8, until the particle that material is ground into required syllabus number, material flows out through the discharging opening 2 that tilts automatically again.

The whole machine using stainless steel material is made, and long-term use can not produce phenomenons such as burn into spot corrosion, corrosion, can be widely used in industries such as pharmacy, chemical industry, metallurgy, food.

More than describing is the explanation to the utility model, is not the qualification to utility model, and the utility model institute restricted portion within the protection domain of the utility model, can be done any type of modification referring to claim.
