Abstract

The utility model discloses a reciprocating jig type pulverizer, belonging to the field of pulverizer. An eccentric shaft and an end eccentric bearing for the eccentric shaft are arranged in a bearing seat bracket at one side of the tail end of a principal shaft of an existing pulverizer; the eccentric bearing is disposed in an eccentric shaft limiting frame on a case; and the other end of the eccentric shaft is connected with a principal shaft through a belt wheel. The eccentric bearing can run with the principal shaft synchronously or slows down to drive the case to have reciprocating vibration with small frequency and big amplitude, and both the frequency and the amplitude of the vibration are adjustable so as to screen various materials quickly. The pulverizer is capable of finishing the processes of super-fine grinding, fine grinding, rough grinding and quick screening. The pulverizer is novel and unique in structure, and simple and convenient to manufacture, and can save energy, reduce consumption, remarkably reduce production cost and obviously improve grinding efficiency and is economic and practical. Therefore, the reciprocating jig type pulverizer is suitable for popularization.

Description

Reciprocating screen dynamic formula pulverizer

Technical field

The utility model relates to a kind of process equipment, a kind of process equipment that material can be pulverized of more specifically saying so.

Background technology

Pulverizer is the special equipment of comminuting matter, along with the development of society, and the progress of science and technology and the raising of mechanization level, pulverizer is in the processing of grain, feed, food, and multiple fields such as medicine, building materials production are more widely used.Among the patent No. 200720094134.X disclosed a kind of pulverizer be a kind of simple in structure, be easy to processing and manufacturing, the pulverizing process equipment that crush efficiency is higher has been brought into play due effect in the material crushing process to above-mentioned field.But because the swinging and under the cooperation of casing sieve aperture material being sifted out of casing (casing), what lean on is that vibrating motor realizes that with being connected of casing especially vibrating motor has fixing vibration frequency and amplitude, and its vibration frequency is big, and amplitude is little.And can't regulate for pulverizing different materials, so unit can not realize the sifting out of different material, it is undesirable to make pulverizer sift out effect, directly influences the pulverizer operating efficiency.

Summary of the invention

The purpose of this utility model is to solve the deficiency that the vibration frequency of taking to vibrate the pulverizer existence of sifting out in the prior art is big, amplitude is little and can't regulate, thereby a kind of reciprocating screen dynamic formula pulverizer is provided.Sift out effect and complete machine operating efficiency with raising.

This utility model is to be achieved by following technical proposals: this pulverizer comprises wheel, main shaft, spindle bearing holder, housing bushing, housing bearing seat, casing, bearing bracket, base, in the terminal side shaft holder support of main shaft, eccentric shaft and this axle head capacity eccentric bearing are set, and capacity eccentric bearing placed in the spacing basket of eccentric shaft on the casing, the eccentric shaft other end is connected with main shaft through belt pulley.

The beneficial effects of the utility model: this pulverizer is provided with the capacity eccentric bearing in spacing basket, make eccentric shaft and capacity eccentric bearing synchronous or decelerate under the drive of main shaft, meanwhile impel casing to produce double vibrations, the vibration frequency of this vibration is little, amplitude is big, after under effect of inertia, sifting out fast less than the material of sieve aperture, break away from the sieve sheet under than the large amplitude effect and takeoff greater than the material of sieve aperture, smashed repeatedly by the hammer leaf that main shaft drives, follow easily generation circulation layer of hammer leaf rotation thereby overcome material, can not in time sift out the direct problem that influences operating efficiency.Secondly, also can regulate the degree of eccentricity of capacity eccentric bearing and the diameter of belt pulley, change the amplitude and the vibration frequency of casing swing, realize sifting out fast different material with this according to the difference of comminuting matter.Make a machine can finish that fine pulverizing, fine powder are broken, the task of sifting out fast of coarse crushing.It is one-machine-multi-function.This machine has also that structural design is novel unique, processing and manufacturing is simple and easy to do, energy-saving and cost-reducing economical and practical, obviously reduce production costs, significantly improve crush efficiency, advantage such as be fit to apply more.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment reciprocating screen dynamic formula pulverizer of the present utility model is described in further detail:

Reciprocating screen dynamic formula pulverizer of the present utility model by to take turns 1, main shaft 2, spindle bearing holder 3, housing bushing 4, housing bearing seat 5, casing 6, bearing bracket 7, base 8, eccentric shaft 9, capacity eccentric bearing 10, spacing basket 11,

belt pulley

12,13, belt 14, eccentric shaft bearing seat 15 constitute.It is to set up belt pulley 12 at main shaft 2 ends, connect belt pulley 13 by belt 14, belt pulley 13 is fixed on main shaft 2 below bearing brackets 7 inner eccentric shafts 9 one ends, eccentric shaft 9 other ends connect capacity eccentric bearing 10, capacity eccentric bearing 10 places in the spacing basket 11 of the eccentric shaft on the casing 6, and eccentric shaft 9 is supported by eccentric shaft bearing seat 15.

During work, main shaft 2 rotation at a high speed, the hammer leaf that drives in the casing 6 is pulverized material, drive eccentric shaft 9 axle head capacity eccentric bearings 10 simultaneously and in spacing basket 11, do eccentric motion, give spacing basket 11 transmission of power, impel spacing basket 11 to be that the center of circle, housing bushing 4 are that fulcrum is reciprocating with main shaft 2 together with casing 6.In this process, the material of failing to sift out takeoffs from the sieve sheet every now and then, and is smashed once more by the hammer leaf that main shaft drives, and so moves in circles, and effectively overcomes circulation layer and improves the grinding screen output greatly, significantly improves the complete machine operating efficiency.
