Description

A kind of twin-shaft crusher
Technical field
The utility model relates to a kind of size reduction machinery, is a kind of twin-shaft crusher specifically.
Background technology
The pulverizing of feedstuff is a very important link in the feed processing, by pulverizing the total surface area that can increase the unit mass feed particles, increases the solubility of feed nutrient in animal digestion liquid, improves the digestibility of animal; Simultaneously, the size of pulverizing raw material granularity has very important impact to complexity and the end product quality of subsequent handling (as granulating etc.); And the size of grinding particle size directly affects production cost, and when producing powdery compound feed, the power consumption of pulverizing process is about 50%~70% of total power consumption.Grinding particle size is less, more is conducive to animal digestion and absorbs, also more be conducive to granulate, but the corresponding increase of simultaneously power consumption meeting, vice versa.At present, known technology is hammer type feedstuff crasher, it comprises casing and is installed in the interior armature spindle of casing, have on the armature spindle rotor disk that hammer leaf is used is installed, there is the pass sieve plate periphery, also have in addition centrifugal material discharging machine and rotor mill axle coaxial rotation, power adopts motor or diesel engine, effective equipment of farm or plant processing feed, but it has an open defect: because employing is the single axle running, feedstuff is not just to have pulverized moment in pulverizer, but will be through the long time, by the repeatedly bump of hammer leaf and feedstuff, thin crushed material is discharged by sieve aperture, thick crushed material is stayed and is continued in the pulverizer to pulverize, so crushing effect is unsatisfactory, has also affected crushing efficiency.
The utility model content
The purpose of this utility model is to provide a kind of twin-shaft crusher, and this twin-shaft crusher can improve the fodder crushing effect, improves fodder crushing efficient.
For addressing the above problem, the utility model is by the following technical solutions: a kind of twin-shaft crusher, comprise housing, charging aperture, rotor and motor, described rotor is positioned at housing, rotor is provided with rotor disk, it is characterized in that described rotor has two, described two rotors flatly are arranged in parallel within the described housing; Each rotor correspondence arranges a motor, described two equidirectional runnings of motor.
Described rotor disk has 17, they evenly are nested with on main shaft by flat key, be provided with main shaft distance bushing between the adjacent rotor disk in twos, on each rotor disk along circumferential uniform six hammer leaves of rotor disk, be provided with the hammer leaf spacer between each hammer leaf and the adjacent rotor disk, the six roots of sensation is serially connected described 17 rotor disks and hammer leaf along the uniform bearing pin of periphery of rotor.
Described two rotors are installed along the axial dislocation 10mm of rotor.
Described charging aperture is provided with two and be positioned at described case top.
Described housing comprises upper shell and lower house, and described upper shell is movably arranged on the described lower house.
The beneficial effects of the utility model are:
1, owing to is provided with the rotor of two equidirectional runnings, when the feed after pulverizing through a rotor drops between two rotors, the pound of the double linear speed of feed that another rotor falls has from bottom to top improved crushing effect and crush efficiency greatly.
2, owing to be provided with two rotors simultaneously, increased the pulverizing chamber space, enlarged the pulverizing area, when improving crush efficiency, alleviated the intense impact of feed to sieve, also protected to greatest extent sieve, prolonged more than 1 times the service life of sieve.
3, can forward and reversely turn round owing to each motor, and be provided with two charging apertures, therefore can match with various forms of feeding mechanisms.
4, owing to adopted built-in rotor, reached and pulverized without the dead angle, product grading is more even.
5, be movably arranged on the described lower house owing to upper shell, for convenience detach, therefore easy to maintenance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model;
Fig. 3 be among Fig. 1 A-A to profile;
Fig. 4 is the top views of 2 rotors in lower house.
Among the figure: 1 housing, 11 upper shells, 12 lower houses, 2 charging apertures, 3 rotors, 31 rotor disks, 32 flat keys, 33 main shafts, 34 main shaft distance bushings, 35 bearing pins, 36 hammer leaves, 37 hammer leaf spacers, 4 motors, 5 sieves, a distance that axially misplaces.
The specific embodiment
Such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of twin-shaft crusher comprises housing 1, charging aperture 2, rotor 3 and motor 4, and its rotor 3 has two, and they flatly are arranged in parallel within the housing 1, also are provided with rotor disk 31 on the rotor 3; But each rotor correspondence arranges the motor 4 of a High Rotation Speed, two altogether, and these two equidirectional runnings of motor,, namely direction of rotation is identical.And each motor can forward or counter-rotating, to adapt to different feeding mechanisms.
Rotor disk 31 can arrange 17, they evenly are nested with on main shaft 33 by flat key 32, between adjacent in twos rotor disk 31, be provided with main shaft distance bushing 34, on each rotor disk 31 along rotor disk 31 circumferential uniform six hammer leaves 36, be provided with hammer leaf spacer 37 between each hammer leaf 36 and the adjacent rotor disk 31, the six roots of sensation is serially connected these 17 rotor disks 31 and hammer leaf 37 along rotor 3 circumferential uniform bearing pins 35.
Two rotors 3 are that 10mm installs along the axial dislocation of rotor 3 apart from a, such hammer leaf interlaced arrangement, and crushing effect is more obvious.
Charging aperture 2 is provided with two, and is positioned at housing 1 top, can according to different which charging apertures of feeding mechanism choice for use, also can carry out simultaneously feeding by two charging apertures.
Housing 1 can also be arranged to two parts: upper shell 11 and lower house 12, and connect by bolt, upper shell 11 is movably arranged on the lower house 12, for convenience detach, maintenance.
During use, such as Fig. 3, Fig. 4, suppose to select the charging aperture feeding on the left side, this moment, motor should turn clockwise, and was High Rotation Speed, drove two equidirectional High Rotation Speeds of rotor.After material enters, partial material is subject to moving to from left to right between two rotors after the epitrochanterian hammer leaf in left side clashes into and drops from top to bottom, the left-hand component of the rotor on the right of this moment has been carried out bump from bottom to top to the partial material that falls again, form the strong bump of double linear speed, material moment change direction falls on the sieve 5 from the right side of the son of turning right from top to bottom, this moment, most materials reached the granularity that needs, fall from sieve 5, reduced the impact to sieve 5, the thick material of residue minority continues rotation under the action of high-speed airflow of the High Rotation Speed formation of right side rotor, until reach the granularity that needs.If use the charging aperture on the right, the course of work is the same, and just material traffic direction and motor rotation direction are with above-mentioned opposite.Two charging aperture while blankings also can play the effect of pulverizing.
The above, principles more of the present utility model just explain through diagrams, this specification be not be the utility model to be confined to shown in described concrete structure and the scope of application, so every corresponding modify that might be utilized and equivalent all belong to the claim that the utility model is applied for.
