Abstract

The utility model relates to feed production, and particularly relates to a grinder in production. The utility model aims to provide an efficient and energy-saving feed grinder. The technical scheme of the utility model is as follows: a hammer feed grinder comprises a hammer; the hammer is lath-shaped, and provided with open holes, wherein the open holes are triangular, and 2-3 open holes are uniformly arranged along the length direction of the hammer; the vertex of each triangular open hole faces to the outer end of the hammer, and two edges defining the vertex are groove-shaped. The groove shape can also mean a knife edge shape. Such open holes do not break the external contour of the hammer, so that the hammer impacts and cuts feeds in the process of high-speed running is ensured; the weight of the hammer is reduced, and the energy consumption for equipment running is reduced. Meanwhile, when the open holes are running, the edges of the holes also can achieve cutting and impacting effects on feeds, which equivalently increases the working surface of the hammer. Therefore, the grinding efficiency of the whole grinder is improved, the energy consumption is significantly reduced, and an efficient and energy-saving significant technical effect is achieved.

Description

A kind of hammer type feedstuff crasher

Technical field

The utility model relates to Feed Manufacturing, is specifically related to the pulverizer in producing.

Background technology

Feed grinder is mainly used in pulverizing all feeds or feedstuff.The object of fodder crushing is to increase feed surface area and adjust granularity, increases surface area and has improved palatability, is conducive to improve digestibility.Meanwhile, pulverize raw material granularity size on subsequent handling (as granulate etc.) complexity and end product quality have very important impact.And the size of grinding particle size directly affects production cost, in the time 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, and be also more conducive to fodder granulating machine and granulate, but power consumption can corresponding increase simultaneously.

China pulverizes every year processing total amount and reaches more than 200,000,000 ton.Feed grinder, as the main equipment of feed industry, is a key factor to the formation of feeding quality, the price of deed, feed processing cost.So the properity of feed grinder improves, restricting the restraining factors of overall technology level, the especially power consumption of polymer processing of China's field of feed processing.

Beater disintegrating machine is to utilize the hammer leaf of High Rotation Speed to smash the machinery of feed.It is high and use the features such as safety that it has simple in structure, highly versatile, productivity ratio.In fodder crushing, have a wide range of applications.But the crush efficiency of beater disintegrating machine is lower at present, and energy consumption is large.

Summary of the invention

The purpose of this utility model is to provide a kind of energy-efficient feed grinder.

For achieving the above object, the utility model has adopted following technical scheme: a kind of hammer type feedstuff crasher, comprises hammer leaf; It is characterized in that: described hammer leaf is lath-shaped, perforate is set on hammer leaf, described perforate is triangle and is evenly arranged to 2-3 along hammer leaf length direction; The summit of described leg-of-mutton perforate towards hammer leaf outer end, form the both sides on summit and be groove shape.It is the edge of a knife that this groove also can be understood as.

The beneficial effects of the utility model are: it is to offer several perforates on the hammer leaf using at existing any beater disintegrating machine that the utility model can be understood as.First, such perforate does not destroy the exterior contour of hammer leaf, guarantees the shock to feed, dissection when hammer leaf runs up; But hammer leaf weight saving simultaneously, equipment work Energy Intensity Reduction.Meanwhile, perforate is in operation, and bore edges also can play cutting, the effect of impact to feed, has been equivalent to increase the working face of hammer leaf.The crush efficiency of whole like this pulverizer improves, and energy consumption significantly reduces.Obtain energy-efficient remarkable technique effect.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of hammer leaf of the present utility model.

The specific embodiment

Kind hammer type feedstuff crasher as shown in Figure 1, general structure similarly to the prior art, also can make further improvements.Normally motor 1 drives rotating shaft 5 to rotate, and rotating shaft 5 is positioned at crush box 4; Charging aperture 3 and discharging opening 2 are set on crush box 4.The raw materials such as corn, soybean, stalk enter crush box 4 by charging aperture 3, driven by rotating shaft 5 and at a high speed around the shaft the hammer leaves 6 of 5 motions clash into, shear pulverizing, through discharging opening 2 dischargings.Conventionally discharging opening 2 inside arrange screen cloth, guarantee that the raw material of pulverizing out reaches certain fineness.

In conjunction with shown in Fig. 2, described hammer leaf 6 is common lath-shaped, and also can be called is sheet, is generally formed by steel plate cutting, and end arranges installing hole 7, is convenient to be connected on pulverizer.Core of the present utility model is improved and is to arrange on hammer leaf 6 perforate 8.Perforate 8 does not destroy the exterior contour of hammer leaf 6, guarantees shock, dissection to feed when hammer leaf 6 runs up; But hammer leaf 6 weight savings simultaneously, equipment work Energy Intensity Reduction.Based on above-mentioned theory analysis, the shape of perforate 8 should be arbitrarily.

But process practical proof: the shape of perforate 8 still needs there is certain restriction, because perforate 8 can reduce the weight of hammer leaves 6, also can weaken the effect of impact of hammer leaf 6 to feed to a certain extent.For this reducing tendency of balance, perforate 8 of the present utility model is evenly arranged to 2-3, as shown in Figure 1, 2 for triangle and along hammer leaf 6 length directions.

And the summit of leg-of-mutton perforate 8 towards hammer leaf outer end, form the both sides on summit and be groove shape.It is to grind or forge the edge of a knife 9 on adjacent both sides, summit that this groove shape also can be understood as.When hammer leaf 6 is worked like this, move along the direction that is parallel to paper, the grindability of material is significantly improved, and there is energy-saving effect simultaneously.Use after a period of time, installation direction that can integral replacing hammer leaf 6 after side tool mouth 9 wearing and tearing, continues to use; Save hammer leaf 6 use costs.

Meanwhile, according to use experience, the edge of perforate 8 should not be less than 16mm to the outer peripheral minimum range of hammer leaf 6.For example, in the utility model, be obviously that the summit of perforate 8 in outside is nearest from hammer leaf 6 outer ends, distance herein should not be less than 16mm.Avoid hammer leaf 6 outward flanges to be worn through to the part between perforate 8, minimum range now need not be considered the width dimensions of the edge of a knife 9.

Utilize the crush efficiency of the improved pulverizer of the utility model to improve, energy consumption significantly reduces.Obtain energy-efficient remarkable technique effect.
