Abstract

The utility model provides a jaw crusher which comprises a crushing cavity formed by a left lateral protecting sheet, a right lateral protecting sheet, a fixed toothed plate and a movable toothed plate. The upper and the lower edges of the cavity adopts a feed opening and a discharge opening; the plate faces of the fixed toothed plate and/or the movable toothed plate are saw-toothed, so as to form a saw-toothed crushing cavity; and the incline direction of the crushing toothed surfaces forming the sawtooth is the reducing direction of the engage angle between the plate face of the fixed toothed plate and the plate face of the movable toothed plate. The jaw crusher provided by the utility model can effectively reduce engage angle and increase the output of the crusher under the condition that the height, the volume, and the weight of the crusher are not increased.

Description

A kind of jaw crusher

Technical field

The utility model provides a kind of jaw crusher.

Background technology

Jaw crusher of the prior art has various ways, as simple swing jaw crushing apparatus, complicated swing jaw crushing apparatus, the negative jaw crusher that supports, external jaw jaw crusher etc., this class disintegrating machine changes howsoever, all has a crusher chamber, this crusher chamber generally is meant by left and right side backplate 11, the space that fixed tooth plate 10 and swing tooth plate 12 surround, and the last bottom in this space is respectively charging aperture and discharging opening.It is trapezoidal that the outline line of the vertical section in this space generally is approximately, as shown in Figure 1, has an angle δ between the plate face of described fixed tooth plate and the swing tooth plate plate face, it is an ip angle, and ip angle is important structural parameters of jaw crusher, generally speaking, the more little output of ip angle is high more, but the height increase that reduces to make disintegrating machine of ip angle causes the increase of volume and weight accordingly.

Reducing ip angle for not increasing the disintegrating machine height in the prior art has multiple improvement project, for example, the curve of fixed tooth plate and/or swing tooth plate is made circular arc, straight line and circular arc combination shape, complex curve shape or broken line shape etc.These tooth plate shapes make troubles to processing and manufacturing, and can make the crusher chamber volume reduce, in addition, the disintegrating machine of linear pattern tooth plate has the characteristic that tooth plate can exchange use up and down, after the wearing and tearing of the bottom of tooth plate, it can be turned upside down re-uses, and prolongs the service life of tooth plate thus, and the use of all can't turning upside down of the tooth plate of above-mentioned various remodeling, the utilization rate of tooth plate reduces.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of jaw crusher that can reduce ip angle under the situation of the height that does not increase disintegrating machine and volume, weight is provided.

The jaw crusher that the further purpose of the utility model is to provide a kind of its tooth plate can turn upside down and use.

The utility model purpose can realize in the following way:

The jaw crusher that the utility model provides comprises by the left and right side backplate, the crusher chamber space that fixed tooth plate and swing tooth plate surround, the last bottom in this space is respectively charging aperture and discharging opening, the plate face of wherein said fixed tooth plate and/or swing tooth plate is a zigzag, constitute zigzag crusher chamber chamber type, the incline direction of forming the broken flank of tooth of described sawtooth is to make the plate face of described fixed tooth plate and the direction that the ip angle between the swing tooth plate plate face reduces.

Further, described swing tooth plate or fixed tooth plate can be tooth plates, also can be combined by several tooth plates.

An optimal technical scheme is: described several tooth plates combine up and down and form described swing tooth plate or fixed tooth plate, and each piece tooth plate shape, size are identical up and down, can mutual alternative install.

The jaw crusher that the utility model provides has following advantage compared to existing technology: by swing tooth plate or fixed tooth plate are designed to sawtooth, under the situation of the height that does not increase disintegrating machine and volume, weight, can effectively reduce ip angle, improve the output of disintegrating machine, perhaps under the identical situation of ip angle, can reduce the height and the weight of disintegrating machine, improve the intensity and the reliability of disintegrating machine.Further, if described swing tooth plate or fixed tooth plate are combined by several tooth plates foot, can realize that then tooth plate replaces the purpose that prolongs the service life of tooth plate up and down.

Description of drawings

Fig. 1 shows the structural representation of its crusher chamber vertical section for jaw crusher of the prior art;

The plan structure schematic diagram of the jaw crusher that Fig. 2 provides for the utility model;

Fig. 3 is the A-A sectional structure schematic diagram of jaw crusher shown in Figure 2, demonstrates the shape of crusher chamber vertical section.

The specific embodiment

As shown in Figure 1, ground as prior art, jaw crusher comprises a support body 7, which is provided with a main shaft 5, the one end connects a drive pulley 6, connect drive motors by tape handler, the swing tooth plate that sets firmly disintegrating machine on this main shaft promptly moves the upper end of jaw 4, and the lower end of this moving jaw 4 connects bracket 9 and adjusts seat 8; With moving jaw 4 opposite positions fixed tooth plate 1 is set on support body 7, on the support body at moving jaw 4 and fixed tooth plate 1 two ends side guard plate 2 is set, fixed tooth plate 1, two side guard plates 2 and moving jaw 4 constitute crusher chamber.

Fixed tooth plate 1 is made up of two block-shaped, big or small identical tooth plates up and down, it can mutual alternative be installed, the plane of disruption of these two fixed tooth plates 1 is the inclined plane that has an angle theta with the perpendicular of the support body of fixing this fixed tooth plate, make the top of the plane of disruption tilt to moving jaw 4, the plane of disruption of the fixed tooth plate of two described tooth plate compositions is described zigzag, so the plane of disruption of whole fixed tooth plate is a zigzag.Moving jaw 4 the fixed distance tooth plate farthest the time and the angle between the described perpendicular be α, the angle between the plane of disruption of fixed tooth plate 1 and moving jaw is that ip angle is β.

β＝α-θ

Hence one can see that, forms the θ angle that the incline direction of the broken flank of tooth of described sawtooth forms, and makes ip angle be reduced under the situation that the height of disintegrating machine does not increase.

And fixed tooth plate is made by two shapes, the identical two boards of size are formed up and down, can so that plate that in use can be top after following plate wearing and tearing and below the installation of plate reversed position, in addition, can also change a plate that damages separately, and the plate that does not have to damage is continued to use.

In addition, except the plane of disruption of fixed tooth plate is made the zigzag scheme, the plane of disruption that moves jaw can also be made zigzag.Can also simultaneously the plane of disruption of fixed tooth plate and moving jaw all be made zigzag.Forming its plane of disruption of the zigzag plane of disruption is the inclined-plane, and processing is got up and wanted simple, convenient compared with being processed into curved surface.

Therefore, the jaw crusher that the utility model provides reduces ip angle under the situation that does not increase the disintegrating machine height, thereby reaches the purpose that reduces device height, increases output, weight reduction, has guaranteed that disintegrating machine has good performance; On the other hand, under the identical situation of ip angle, can reduce the height and the weight of disintegrating machine, improve the intensity and the reliability of disintegrating machine.
