Abstract
The utility model provides a lug groove toothed plate applied to a jaw crusher. According to the lug groove toothed plate applied to the jaw crusher, lugs on a toothed plate are distributed in a longitudinal tooth valley direction according to the following regulations: all of the lugs are uniformly distributed at intervals which are 50-200 times of the crushing granularity. A bottom plate part is mainly used for protecting a moving jaw and a fixed jaw and preventing the moving jaw and the fixed jaw from directly contacting materials, so that the moving jaw and the fixed jaw are not abraded by the materials. A tooth-shaped part of the toothed plate significantly influences the crushing efficiency and the machine-hour yield of the jaw crusher. Therefore, the structure, size and service life of the tooth shape are the key factors in high-efficiency crushing and long-term stable operation of the jaw crusher. The lug groove toothed plate is reasonable in structure and simple to manufacture, the energy consumption of the jaw crusher is effectively reduced, a high crushing efficiency is maintained, the service life of the toothed plate is prolonged, and a reliable guarantee is provided for the jaw crusher in high-efficiency, low-consumption and stable operation.
Description
Technical field
The utility model relates to the disintegrating machine technical field, is specifically related to jaw crusher projection groove tooth plate.
Background technology
Jaw crusher is commonly called as jaw broken, by moving jaw with decide two jaws of jaw and form crusher chamber, two jaw movements of simulated animal and finish the disintegrating machine of material crushing operation.Be widely used in the fragmentation of various ores and brittle material in the industries such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry.
The tooth plate of jaw crusher can be divided into profile of tooth (general designation of tooth peak and tooth paddy shape) part and bottom parts.The tooth plate of jaw crusher has two, movable tooth plate is called swing tooth plate, fixed tooth plate is called fixed tooth plate, swing tooth plate and fixed tooth plate form crusher chamber, the tooth peak of the swing tooth plate in the crusher chamber and tooth peak and the tooth paddy of tooth paddy and fixed tooth plate are staggered mutually, i.e. the tooth peak of the corresponding fixed tooth plate of tooth paddy of the tooth paddy of the corresponding fixed tooth plate in the tooth peak of swing tooth plate or swing tooth plate.The Main Function of parts of tooth, be to the material in the crusher chamber apply pressure, split, the compound action power such as curved, come more effective broken material; The Main Function of bottom parts is the moving jaw of protection and decide jaw, makes jaw and decides jaw and directly do not contact with material, thereby do not worn and torn by material.The parts of tooth of tooth plate is most important on the impact of the crushing efficiency of jaw crusher and unit-hour output.So, be the jaw crusher high efficiency key of moving broken and steady in a long-term the service life of the structure of profile of tooth and size and profile of tooth.
Existing toothed plate of jaw crusher, to how reducing the particularly abrasion deformation at tooth peak of parts of tooth, do not give due attention, the tooth plate that causes existing various profiles of tooth (take triangle, trapezoidal as main), after using the short period, heavy wear just occurs in profile of tooth, just great changes will take place for tooth depth and shape, the crushing efficiency of jaw crusher descends thereupon, and marker size obviously increases, and the overall performance index of jaw crusher is descended.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model provides a kind of rational in infrastructure, and is easy to use, effectively reduce the profile of tooth deterioration, improve crushing efficiency, can keep the reliability of jaw crusher efficiency crushing, effectively prolong the tooth plate projection groove tooth plate in service life.
The technical scheme that the utility model adopts is as follows:
Jaw crusher distributes according to rule as described below on tooth paddy is vertical with projection groove tooth plate, the position of tooth plate upper protruding block with projection groove tooth plate, described jaw crusher: all bump pitch are pressed 50～200 times of even distributions of particle size after cracking.
Preferably, described projection is divided into the Three regions distribution; 1/3 zone on the described tooth plate, 150～200 times of distributions that the bump pitch in its zone is pressed particle size after cracking; 1/3 zone in the described tooth plate, 100～150 times of distributions that the bump pitch in its zone is pressed particle size after cracking; 1/3 zone under the described tooth plate, 50～100 times of distributions that the bump pitch in its zone is pressed particle size after cracking.
Preferably, on the described tooth plate under 1/3 zone and the tooth plate 1/3 zone formation be arranged symmetrically with, bump pitch is pressed 50～200 times of distributions of particle size after cracking, the middle 1/3 part bump pitch of tooth plate is pressed 100～150 times of particle size after cracking, and 1/3 zone, tooth plate upper and lower is not identical with the bump pitch in middle 1/3 zone of tooth plate.
Preferably, tooth plate upper protruding block height is 0.5～1 times of tooth depth.
Preferably, tooth plate upper protruding block length is 1～3 times of tooth peak width.
Preferably, tooth plate upper protruding block width is the width of tooth paddy.
Preferably, the distribution of tooth plate upper groove and size are consistent with distribution and the size of the tooth plate projection that matches.
The utility model has designed groove and projection owing to adopting said structure according to certain rules at tooth peak, the tooth paddy place of tooth plate; The groove of tooth plate is complementary with the projection of the tooth plate that matches, and the projection of tooth plate is complementary with the groove of the tooth plate that matches, and such structure is subject to take bending force as main crushing force material in crusher chamber.The compression strength of material is far longer than the bending strength of material, and namely less bending force just can make material produce and pulverize.So, adopt structure of the present utility model can make material under less crushing force, produce pulverizing, the crushing efficiency of jaw crusher is obviously improved, energy consumption significantly descends.Simultaneously, because the existence of projection and groove weakens the rubbing effect between material and the liner plate, the wearing and tearing of tooth plate are reduced.Therefore, significantly improve the service life of tooth plate.
In sum, the utility model is rational in infrastructure, makes simply, effectively reduces the energy consumption of jaw crusher, keeps higher crushing efficiency, prolongs the service life of tooth plate, and reliable guarantee has been played in steady running efficient to jaw crusher, low consumption.
