Abstract

The utility model discloses a pulverizing blade member of a sugarcane top pulverizer, including a knife wheel shaft, a plurality of knife rests and a plurality of blades; each blade is fixed on the knife rest by the bolt; and the plurality of knife rests are welded on the knife wheel shaft in a stagger way and the gravity center position of the knife rests and the knife wheel shaft are located on the shaft axis of the knife wheel shaft; there are 16 knife rests; the distance between adjacent knife rests in the axial direction is 30mm and an interval angle between adjacent knife rests in the circumferential direction is 22.5 DEG. Because the plurality of knife rests are welded on the knife wheel shaft in a stagger way and the gravity center position of the knife rests and the knife wheel shaft are located on the shaft axis of the knife wheel shaft, the pulverizing blade does not repeat to move, the dynamic balance is kept well, the material does not move in the axial direction in operation and the power consumption is small.

Description

A kind of pulverizing knife assembly of sugarcane top pulverizer

Technical field

The utility model relates to a kind of pulverizer that is applicable to sugarcane top pulverizing and other crushed stalk, specifically is a kind of pulverizing knife assembly of sugarcane top pulverizer.

Background technology

China's sugarcane top total amount is abundant, but they are at present most of by on-site incineration, burns and produces a large amount of smog often, severe contamination air, also easy initiation fire and cause waste to resource.And sugarcane top can produce biogas by anaerobic fermentation, be the good raw material of producing biogas, it is carried out recovery energy is a new way of opening up in recent years, but because the content of cellulose of sugarcane top is higher, in order to satisfy the requirement that marsh gas fermentation process is produced, need earlier it to be pulverized.

The pulverizer that is used for the straw pulverizing at present mostly is beater disintegrating machine, power consumption is big, supporting power generally is higher than 7.5kW, hammer leaf adopts radial type to install, arrange helix arrangement mode or the symmetric arrays modes of adopting more on its break bar axle, rotating speed generally all is higher than 2000r/min, but exist when being arranged in the break bar rotary operation material is moved vertically owing to helix, the wearing and tearing of aggravation hammer leaf, and it is inhomogeneous that the break bar axle is in axial direction loaded, unbalanced moments occurs, make machine produce the shortcoming of vibrations; The shortcoming that symmetric arrays has the hammer leaf movement locus to repeat.

The utility model content

In order to overcome above-mentioned deficiency, the utility model purpose is to provide a kind of Disintegrating knife movement locus not repeat, and dynamic balancing is good, and material does not move axially during operation, the pulverizing knife assembly of the sugarcane top pulverizer that power consumption is little.

To achieve these goals, the technical solution adopted in the utility model is: a kind of pulverizing knife assembly of sugarcane top pulverizer, include break bar axle, a plurality of tool rest, a plurality of blade, each blade is installed on the tool rest with bolting, and described a plurality of tool rests are staggered with welding manner and are distributed on the break bar axle and the position of centre of gravity of a plurality of tool rest and break bar axle is positioned on the axial line of break bar axle.

Described tool rest has 16, and axial adjacent tool rest spacing is 30mm, and circumferential adjacent tool rest angular interval is 22.5 °.

Described 16 tool rests from 1 to 16 sort successively along the axial direction of break bar axle, and tool rest is 1-12-15-9-3-11-4-16-6-2-14-8-10-7-13-5 by job order along circumferentially being arranged in order of break bar axle.

The beneficial effects of the utility model: be distributed on the break bar axle and the position of centre of gravity of a plurality of tool rest and break bar axle is positioned on the axial line of break bar axle because a plurality of tool rests are staggered with welding manner, guaranteed that not only the Disintegrating knife movement locus does not repeat, and can also guarantee dynamic balancing, material does not move axially during operation, and power consumption is little.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

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

Fig. 2 is the utility model expanded view.

Among the figure: 1, bolt; 2, break bar axle; 3, tool rest; 4, blade.

The specific embodiment

As shown in Figure 1, pulverizer break bar assembly is made up of set bolt 1, break bar axle 2, tool rest 3, blade 4.Described tool rest 3 has 16, is welded on the break bar axle, and its axial adjacent two tool rest spacings are 30mm; Circumferentially angular interval is 22.5 °; Described blade 4 has 16, during installation blade 4 inserted in the tool rests 3, and with a side of bolting tool rest 3.

In above-mentioned each tool rest 3 blade 4 is installed all, blade 4 is limited its position by tool rest 3 each limit, makes it not rotate and be fixed in the tool rest 3 around bolt shaft.

As shown in Figure 2, described 16 tool rests sort from 1 to 16 successively along the axial direction of break bar axle, i.e. the 1st tool rest, the 2nd tool rest, by that analogy, to to a last tool rest: the 16th tool rest, these 16 tool rests are the 1st tool rest by job order along circumferentially being arranged in order of break bar axle---the 12nd tool rest---the 15th tool rest---the 9th tool rest---the 3rd tool rest---the 11st tool rest---the 4th tool rest---the 16th tool rest---the 6th tool rest---the 2nd tool rest---the 14th tool rest---the 8th tool rest---the 10th tool rest---the 7th tool rest---the 13rd tool rest---the 5th tool rest.After distributing by this way on the break bar axle, make the break bar axle in the process of work, can keep balance, more steady when the break bar axle is rotated, greatly reduce the vibration of machine, thereby make the equipment safety and reliability, and prolonged the service life of equipment.
