Abstract
The invention provides a jaw crusher toggle plate. The jaw crusher toggle plate comprises a toggle plate body (2) and wear-resisting bodies (1) at the two sides of the toggle plate body (2), wherein the two sides of the toggle plate body (2) are provided with steps, and the wear-resisting bodies (1) are provided with steps (5) matched with the toggle plate body steps (7). The jaw crusher toggle plate disclosed by the invention has the technical effects that firstly, the two ends of the toggle plate body are provided with the wear-resisting bodies, so that the abrasion between the toggle plate body and a toggle plate cushion is alleviated, the service life of the toggle plate is prolonged for 7-8 times and the utilization rate of materials is greatly improved; secondly, the toggle plate body adopts a casting to guarantee that a jaw crusher cracks when non-crushed materials fall into a machine or a machine is seriously overloaded so as to protect a movable jaw and a rack and achieve a safety effect, and the toggle plate body is convenient to replace; and thirdly, one ends of the wear-resisting bodies are circular-arc-shaped, and good rolling abrasion can be formed between the toggle plate and the toggle plate cushion to alleviate the impact on the toggle plate, so that the equipment can be reliably operated for a long period and the use and maintenance costs of the equipment are reduced.
Description
Technical field
The present invention relates to the novel bracket of a kind of jaw crusher, belong to the crushing mechanism technical field.
Background technology
Jaw crusher extensively applies to the medium size fragmentation of various ores in the industries such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry, and the high compressive strength of the material that is broken is 320MPa.Jaw crusher uses mainly as one-level (coarse crushing and in broken) crushing mechanism.The motion feature that existing jaw crusher is pressed jaw is divided into simple oscillating-type, complicated oscillating-type and mixes three kinds of patterns of oscillating-type, and at present most widely used is complicated oscillating-type.Jaw crusher mainly is made up of rack unit, fixed jaw, moving jaw parts, sewing jaw, bracket, adjustment component, take-up device etc.The moving jaw that has sewing jaw directly is suspended on the eccentric shaft by roller bearing.And eccentric shaft is bearing on the rolling bearing of frame.The bottom of moving jaw is supported on the bracket seat that is positioned at the frame rear wall with bracket.The adjusting device of discharging opening is to utilize the adjusting bolt to change the relative position of drift, thereby the width of discharging opening is regulated.Have pull bar, spring and regulate the take-up device that bolt is formed.By the motor drives belt wheel eccentric shaft is rotated, moving jaw is just driven does complicated swing, realizes the comminuting matter action.
In use there are some problems in jaw crusher at present; mainly be that the bracket of jaw crusher is as the safeties of fragmentation; require jaw crusher to rupture falling under non-broken thing or the seriously overload situation of machine, protected moving jaw and frame, play safety effect.Must change in case just damage, it is quite tired to operate
Difficulty wastes time and energy, and has reduced production efficiency.And bracket generally all adopts cast form, directly installs and uses without machining.Because all multifactor influences such as casting error, technology and material etc., making with the bracket is that the protection point of safety piece has very big discreteness.The wearing and tearing of bracket two node places are severe, change comparatively frequent.Increase maintenance cost, influenced the long-term safety operation of equipment.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, a kind of jaw crusher bracket is provided.
Jaw crusher bracket of the present invention, comprise bracket body (2) and be located at the wear body (1) of bracket body (2) both sides, said bracket body (2) both sides are equipped with step, have the step (5) that matches with bracket body step (7) on the said wear body (1), be equipped with through hole (8) on said wear body (1) and the bracket body (2), said bracket body (2) is provided with casting hole (3).
Preferably,
Said wear body (1) is provided with arc-shaped surface (4).
Jaw crusher bracket of the present invention has following technique effect:
1, bracket body of the present invention adopts two ends to have wear body, has reduced the wearing and tearing with the bracket pad, has increased by 7～8 times service life, and the utilization rate of material is greatly improved.
2, bracket body of the present invention uses foundry goods to guarantee that jaw crusher ruptures falling under non-broken thing or the seriously overload situation of machine, has protected moving jaw and frame, plays safety effect, changes to make things convenient for.
3, wear body one end of the present invention is in the arc-shaped, can be good at forming rolling friction between bracket and the bracket pad, reduced the bump with bracket, thereby the equipment that guaranteed moves reliably and with long-term, has reduced equipment working service cost.
Description of drawings
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present invention;
Fig. 2 is front view of the present invention;
Fig. 3 is the A-A profile of Fig. 2:
Wherein, 1 is wear body, and 2 is the bracket body, and 3 is casting hole, and 4 is arc-shaped surface, and 5 is the wear body step, and 6 is bolt, and 7 is bracket body step, and 8 is through hole.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
As shown in Figure 1 and Figure 2, jaw crusher bracket of the present invention, comprise bracket body (2) and be located at the wear body (1) of bracket body (2) both sides, said bracket body (2) both sides are equipped with step, have the step (5) that matches with bracket body step (7) on the said wear body (1), be equipped with through hole (8) on said wear body (1) and the bracket body (2), said bracket body (2) is provided with casting hole (3).Said wear body (1) is provided with arc-shaped surface (4).Fixing by bolt (6) between wear body (1) and the bracket body (2).
Jaw crusher bracket of the present invention is when work, bracket body (2) and be located between the wear body (1) of bracket body both sides and can be good at forming rolling friction, reduced the bump with bracket, more reasonable stress is reliable, thereby the equipment that guaranteed moves reliably and with long-term, reduce equipment working service cost, improved running rate and the reliability of equipment greatly.
Claims (2)
1. jaw crusher bracket, it is characterized in that, comprise bracket body (2) and be located at the wear body (1) of bracket body (2) both sides, said bracket body (2) both sides are equipped with step, have the step (5) that matches with bracket body step (7) on the said wear body (1), be equipped with through hole (8) on said wear body (1) and the bracket body (2), said bracket body (2) is provided with casting hole (3).
