Abstract

The utility model relates to a feed crushing machine and particularly relates to a roller type rotor of a crushing machine, which is used for crushing and grinding grains. The roller type rotor comprises a main shaft and a pair of outer wheel spokes arranged on the main shaft, wherein a hammer sheet cascading rod is arranged between the outer wheel spokes; the hammer sheet cascading rod is connected with a hammer sheet. The roller type rotor is characterized in that the main shaft is provided with a roller; the roller comprises a cylinder body and a cylinder body fixing part; the cylinder body is fixedly provided with an inner wheel spoke; the cylinder body fixing part is connected with the main shaft; a limiting block is arranged between the cylinder body and the hammer sheet cascading rod. The main shaft drives the roller to rotate at a high speed and the roller drives the hammer sheet to rotate at the high speed through the hammer sheet cascading rod so as to knock and crush materials; the superficial area is relatively reduced by 20% under the condition that the total weight of the rotor is not changed, so that the wind resistance to the rotor operating at a high speed when the rotor works is greatly reduced; the gravity center in a radius direction except the shaft is moved outwards and the moment is enlarged, that is to say, the force for knocking the materials by the hammer sheet is increased; the roller type rotor is good for crushing the materials.

Description

Pulverizer cylinder type rotor
Technical field
The utility model relates to feed grinder, specifically a kind of for pulverizer cylinder type rotor broken, that grind cereal.
Background technology
The pulverizing of feedstuff is a very important link in feed processing, by pulverizing the large total surface area that can increase unit mass feed particles, increases the solubility of feed nutrient in animal digestion liquid, improves the digestibility of animal.But the size of grinding particle size directly affects production cost, when producing powdery compound feed, the power consumption of pulverizing process is about 50%~70% of total power consumption.Grinding particle size is less, is more conducive to animal digestion and absorbs, be also more conducive to granulate, but the corresponding increase of power consumption meeting simultaneously, vice versa.So how to make the little and power consumption of pulverized particles become less the problems of the prior art.
Beater disintegrating machine is to use at present the widest a kind of pulverizer cylinder type rotor, its structure is generally by intake mechanism, pulverizing chamber (rotor, hammer leaf, sieve, tooth plate), discharge part (blower fan, aggregate tube, control of dust cloth bag) three parts form, during work, feed enters pulverizing chamber from intake mechanism, under the strike of the hammer leaf of high speed rotary, fly to tooth plate, after rebounding with tooth plate collision, be again subject to the strike of hammer leaf, simultaneously between compass screen surface and hammer leaf, feed is subject to again strong friction, under strike collision and friction effect repeatedly, feed is pulverized gradually, not with the pulverizer of blower fan, by the air-flow in pulverizing chamber, crushed material is discharged by sieve aperture.With the pulverizer of blower fan, crushed material, from sieve aperture is extracted out, is still needed by powder collection device, as aggregate tube, control of dust cloth bag etc., the air in mixed airflow is separated with pulverizing.
The interior spoke that existing hammer sheet type crusher rotor is provided with, spacer sleeve etc., exist rotor surface area large, and windage during rotor high-speed running work is large, and hammer leaf to impact the dynamics of material little, be unfavorable for the pulverizing of material.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of pulverizer cylinder type rotor, and this device can reduce rotor surface area, thus the windage while reducing rotor high-speed running work; Increase the moment of rotor, thereby increase the pulverizing that hammer leaf impacts the dynamics of material.
For solving the problems of the technologies described above, the utility model adopts following technical proposals:
A kind of pulverizer cylinder type rotor, comprise main shaft, be arranged on a pair of outer spokes on main shaft, between outer spokes, be provided with hammer leaf boom, on hammer leaf boom, connect hammer leaf, described main shaft is provided with cylinder, and cylinder comprises cylindrical shell, cylindrical shell fixed part, is fixed with interior spoke on cylindrical shell, cylindrical shell fixed part is connected with main shaft, between cylindrical shell and hammer leaf boom, is provided with limited block.
In the technical program, main shaft drives cylinder High Rotation Speed, and cylinder drives hammer leaf to carry out High Rotation Speed by hammer leaf boom again, the material that enters pulverizer is impacted, thereby play the effect of pulverizing.
The utility model that adopts technique scheme, compared with prior art, has advantages of following several aspect:
1. interior spoke is fixed on cylinder, and has cancelled the spacer sleeve in conventional rotors, greatly reduces the surface area of interior spoke, and then make the surface area of rotor reduce 20%, windage in rotor high-speed running reduces greatly like this, and the saved power of envoy, for comminuting matter, improves crush efficiency.
2. due to the improvement of rotor structure, make rotor " center of gravity of radial direction " (except axle) radius strengthen 20%, moment increasing since like this, has been equivalent to strengthen the dynamics that hammer leaf impacts material, is conducive to the pulverizing of material.
3. the size of limited block, weight reduces relatively, thereby has also reduced windage, is conducive to pulverize.
4. this device can be improved the crush efficiency of feed.
As the further improvement to the technical program, described cylinder is segmentation structure, is divided into cylinder A, cylinder B, cylinder C, and described cylinder A, cylinder B, cylinder C are provided with interface at adjacent.Cylinder is set to a plurality of parts, can reduce cylinder difficulty of processing, is beneficial to cylinder DE and installs and safeguard; For guaranteeing the stationarity being connected between cylinder and cylinder, at adjacent, be provided with the interface of concave, convex, a cylinder limit for adjacent cylinder can be connected together.
As the further improvement to the technical program, described limited block is fixed on the outer surface of cylindrical shell.
As the further improvement to the technical program, hammer leaf boom is 2-4 couple, and centered by the center of circle, point is equidistantly symmetricly set on same circumference.When hammer leaf boom is 2 pairs, its line is mutually vertical, and the distance between hammer leaf boom is equidistant; When hammer leaf boom is multipair, the angle between two adjacent hammer leaf booms, namely central angle equates.
