Abstract

The utility model discloses a combined fodder grinder. One end of a main spindle on the inner bearing of a casing is fixed with a circular inner rotating disk and a cruciform outer rotating disk whose radial dimension is comparatively small. Pin shafts that are hinged with hammers are installed at the near middle part of the inner rotating disk and the edge part of the outer rotating disk, the central part of the left end cover of the casing is provided with a feed inlet whose inner surface have arc-shaped blades that stretch between blade claws and the hammers, and annular sieve plates surround outside of the blade claws so that a discharge hole is partitioned off grinding. Fodder are milled and grinded by the blades and the blade claws after broken up by hammers with good grinding quality and high productive efficiency.

Description

Combined fodder grinder

The utility model relates to the small-sized feed grinder that a kind of feed grinder, particularly matched power are 3-5 horsepower power.

China's utility model patent discloses a kind of small-sized feed grinder for No. 91216621.5.It is made up of casing, main shaft, bearing, rotating disk, bearing pin, hammer leaf, tooth plate, sieve plate, air exhauster and conduit, behind the technical parameters such as gap of preferred hammer leaf end and tooth plate, it saves power than traditional 370-1 type feed grinder, productivity ratio also improves a lot, but, air exhauster in this pulverizer will consume considerable power, thereby reduced the power of pulverizing, and also more complicated of structure.

Task of the present utility model is the shortcoming that will overcome above-mentioned small-sized feed grinder, designs a kind of air exhauster that do not have, the simple and higher novel combined feed grinder of productivity ratio of structure.

Task of the present utility model is finished like this: be bearing in main shaft left end on the bearing of casing right side is fixed with, outer two rotating disks, inner rotary table is circular, its edge is fixed with L shaped hock, outer rotary table is a cross, its radial dimension is littler than inner rotary table, bearing pin is placed in outer rotary table limit portion and inner rotary table leans on the middle part, be hinged with hammer leaf on the bearing pin, the central part that is contained in the end cap in casing left side has charging aperture, the end cap inner face is extended with the arc gear piece, gear piece is stretched between the gap of hammer leaf and hock, also is fixed with annular sieve plate in the casing, and sieve plate is enclosed in hammer leaf, gear piece and hock outside separate pulverizing chamber and discharging opening.

Because outer rotary table is a cross, feed and air easily enter from charging aperture, the effect that the hammer leaf of high speed rotation and hock can play the air exhauster blade, thereby the utility model can be without air exhauster, structure is simpler, uses, keeps in repair all more convenient.The feed that enters from charging aperture is smashed by hammer leaf earlier, again through arc gear piece and hock mill, pulverize, at last from the discharging opening outflow of casing bottom, thereby this machine good crushing effect not only, productivity ratio is also higher.

Be elaborated below in conjunction with embodiment and accompanying drawing.

Fig. 1 is a longitudinal sectional view of the present utility model, and Fig. 2 is the cutaway view along the A-A line of Fig. 1.Fig. 3 is the profile along the B-B line of Fig. 2.

From accompanying drawing as seen, there are bearing 2 upper supports on right side of the casing 1 of opening that main shaft 3 is arranged in the left side.Left end 4 cantilevers of main shaft are fixed with inside and outside two rotating disks on it in the pulverizing chamber 5 of casing 1, inner rotary table 6 is circular, and its radial dimension is bigger, and edge is fixed with L shaped hock 7.Outer rotary table 8 is a cross, and its radial dimension is littler than inner rotary table 6, is fixed with the bearing pin 9 parallel with main shaft 3 at inner rotary table 6 near the limit portion of middle parts and outer rotary table 8, is connected to hammer leaf 10 on the bearing pin.The end cap 11 that is contained in the left side of casing 1 is sealed the opening in casing left side, end cap 11 central parts have charging aperture 12, the inner face of end cap 11 is extended with arc gear piece 13, gear piece 13 inserts between hammer leaf 10 and the hock 7, hammer leaf 10 is the 3-8 millimeter with the gap of gear piece 13, the gap that gear piece 13 and hock are 7 is the 3-8 millimeter, the annular sieve plate 14 that is fixed on 5 li of the pulverizing chamber of casing 1 is enclosed in outermost, the discharging opening 15 of pulverizing chamber 5 with the casing bottom separated, for ease of charging, there is hopper 16 in the gap that sieve plate 14 and hock are 7 in charging aperture 12 fixed outside between the 8-25 millimeter.

When main shaft 3 drives inner rotary table 6, outer rotary table 8, bearing pin 9, hammer leaf 10, when hock 7 rotates at a high speed, from the big grain feed that hopper 16 is packed into, smashed by hammer leaf 10 earlier, to mill, pulverize through hock 7 and gear piece 13 again, feed meal passes sieve plate 14, flows out from discharging opening 5.
