Abstract

The utility model discloses an upper shell of a grinder cavity, belonging to the technical field of a grinder. The upper shell of the grinder cavity comprises a shell; a feeding hole is arranged on the shell; the shell is internally provided with a lining plate; a plurality of top racks are distributed on the lining plate; a plurality of vertical plates are fixed on the lining plate, just face to all grinding cutter heads, and are parallel to the grinding cutter heads; and a plurality of side racks are respectively fixed on the inner walls of the two sides of the shell. After the upper shell is applied to a grinder, the area and the frequency of impact and grinding can be enlarged and enhanced, so that grinding blades and the racks on the grinder cavity are more fully used for cutting and grinding, the grinding efficiency and effect can be improved, and the fine grinding can be realized.

Description

Pulverizer chamber upper shell

Technical field

The utility model relates to a kind of crusher housing, belongs to the pulverizer technical field.

Background technology

At present, the pulverizer especially crushing chamber of drum-type pulverizer is generally formed by upper and lower two housing sections flexible connection, how the strip tooth is fixedly arranged in the upper shell wherein, match with the Disintegrating knife of rotation, crushed material is carried out cutting rubbing, reach the purpose of pulverizing, so upper shell is commonly called as " dental lamina " again.Strip tooth structure in the existing upper shell is limited to cutting and the friction effect of crushed material, can not pulverize more fully, is difficult to satisfy the more tiny pulverizing requirement of particle.

Summary of the invention

In order to overcome above-mentioned the deficiencies in the prior art part, the utility model provides a kind of pulverizer chamber upper shell, makes that the crushing effect of pulverizer is better, improves and pulverizes fineness and production efficiency.

The utility model is achieved by the following technical solution: a kind of pulverizer chamber upper shell, it comprises housing, charging aperture is arranged on the housing, liner plate is arranged in the housing, be placed with a plurality of apical tooth bars on the liner plate, a plurality of risers are fixedly arranged on the described liner plate, and described riser position faces each position of pulverizing cutterhead, and parallel with the pulverizing cutterhead.

A plurality of side tooth bars are fixedly arranged on the both sides inwall of described housing, and a plurality of side tooth bars are the circular arc direction by the movement locus of Disintegrating knife and arrange.

Fixedly there is the pulverizing tooth bar both sides of described riser.

Be parallel to each other between the described apical tooth bar, and perpendicular with the Plane of rotation of Disintegrating knife.

Described apical tooth bar has many rows, is parallel to each other between every row's the apical tooth bar and tilts to arrange, and the incline direction of adjacent two rows' apical tooth bars is opposite, be " V " font arranges.

Jug on the described housing.

The beneficial effects of the utility model are: the utility model is owing to adopted riser and the apical tooth bar of many row's " V " fonts arrangement, and the side tooth bar of both sides, area and the frequency of bump, grinding have been increased greatly, make cutting between the tooth bar on Disintegrating knife and the crushing chamber, grind more abundant, improved efficient and the effect pulverized, can meticulously pulverize; The utility model is simple in structure, and structure rationally is convenient to promotion and implementation, economic benefit that can be good and social benefit.

Among the figure, 1, charging aperture; 2, housing; 3, liner plate; 4, apical tooth bar; 5, riser; 5-1, pulverizing tooth bar; 6, side tooth bar; 7, handle; 8, pulverize cutterhead; 9, Disintegrating knife; 10, crushing chamber lower house.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, a kind of pulverizer chamber upper shell shown in Figure 4, it comprises housing 2, charging aperture 1 is arranged on the housing 2, liner plate 3 is arranged in the housing 2, be placed with a plurality of apical tooth bars 4 on the liner plate 3, a plurality of risers 5 are fixedly arranged on the described liner plate 3, and described riser 5 positions face each position of pulverizing cutterhead 8, and parallel with pulverizing cutterhead 8.Row's number of riser 5 can be with to pulverize cutterhead 8 corresponding, and the shape of arranging with liner plate of every row's riser 5 changes, and can be three sections circular arcs like that by Fig. 1, also can arc be arranged like that by Fig. 3, straight plate shape is arranged.Jug 7 on the described housing 2.Handle 7 can be located at side or the top of housing 2.

A plurality of side tooth bars 6 are fixedly arranged on the both sides inwall of described housing 2, and a plurality of side tooth bars 6 are the circular arc direction by the movement locus of Disintegrating knife 9 and arrange.

As Fig. 6, shown in Figure 7, fixedly there is the tooth bar of pulverizing 5-1 the both sides of described riser 5.The height of riser 5 is about 5cm, about thick 5mm, and shock resistance, and play certain damping and noise abatement audio fruit.During Disintegrating knife 9 rotation, have very big area and riser 5 both sides pulverizing tooth bar 5-1 friction, bump, grind, this than merely and the apical tooth bar 4 on the liner plate to carry out cutting and grinding efficient many.

Be parallel to each other between the described apical tooth bar 4, and perpendicular with the Plane of rotation of Disintegrating knife 9.

Embodiment as shown in Figure 5, described apical tooth bar 4 have many rows, are parallel to each other between every row's the apical tooth bar 4 and tilt to arrange, and the incline direction of adjacent two rows' apical tooth bars 4 is opposite, be " V " font arranges.Can change the movement locus of material powder, the frequency that has increased bump and ground has improved efficient and the effect pulverized greatly.
