Abstract
The utility model relates to a new compound pendulum jaw crusher, the structural characteristics of which is that firstly, a toggle plate is negative support, and the range of a transmission angle is 90 DEG < beta <135 DEG; secondly, the range of the hanging height of a moving jaw H is-50 <= H <= 50 mm; thirdly, a screw bolt used to fix a movable jaw plate is arranged above the bearing hole of the moving jaw. The utility model has the advantages that the motion characteristic coefficient of the moving jaw is lowered under 1, productivity effect is increased more than 20%, life time of the jaw plate is raised more than 2 times and energy is saved about 20%. Besides, the fastening screw bolt used to fix the movable jaw plate is arranged above the bearing hole of the moving jaw to make dismounting of the movable jaw plate convenient and to protect the movable jaw plate.
Description
The utility model relates to a kind of novel single toggle jaw crusher, belongs to the preparation equipment in the mining machinery.
Jaw crusher at present commonly used structurally has following characteristics: the first, and bracket all adopts positive supporting form (being down-push type again), i.e. drive line angle β＜90 °.The second, the suspension height H of moving jaw is about 50-150mm.The 3rd, the motion feature coefficient of moving jaw (being vertical stroke and the ratio of horizontal throw) reaches 2.0-3.0.The 4th, the fastening bolt 4 that is used for fixing sewing jaw 3 mostly is positioned at moving jaw dead eye below, and individual cases have and are positioned at the top, but sewing jaw is shorter, and fastening bolt is longer.Become flexible in the work and easily.Because the said structure characteristics make it show as shortcomings such as productivity ratio is low, power consumption big, jaw quick abrasion, product granularity feature difference on performance.
The purpose of this utility model is that a kind of moving jaw movement characteristic coefficient is little, productivity ratio is high, power consumption is little and provide at above-mentioned the deficiencies in the prior art part, the single toggle jaw crusher that the jaw life-span is long.
The utility model is achieved in that it is made up of frame, fixed jaw, sewing jaw, moving jaw, eccentric shaft and bracket, and its design feature is as follows:
A, bracket 7 adopt negative supporting (deserving to be called pushing-type again) structure to form, and promptly the scope of drive line angle β is: 90 °＜β＜135 °.
The scope of the suspension height H of b, moving jaw is :-50≤H≤50mm.
The utility model also can adopt following proposal to implement, and promptly when satisfying above-mentioned condition, making fixedly, the fastener shaft bolt 4 of sewing jaw 3 usefulness is positioned at the top of moving the jaw dead eye.
The utility model can also adopt following proposal to implement, though promptly drive line angle β or suspension height H do not satisfy above-mentioned requirements, can with behind the sewing jaw lengthening, fix above moving jaw dead eye with lag bolt.
The optimum value of drive line angle β is selected as 110 °, and the optimum value of the suspension height H of moving jaw is chosen as 0mm.
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated:
Fig. 1 is a structural representation of the present utility model.
1 is frame among the figure, and 2 is fixed jaw, and 3 is sewing jaw, and 4 is fastening bolt, and 5 are moving jaw, and 6 is eccentric shaft, and 7 is bracket.
Fig. 2 is the schematic diagram of expression drive line angle β and moving jaw suspension height H.
β is a drive line angle among the figure, and H is moving jaw suspension height, and B is the charging aperture width, and b is for showing the discharging opening width, and W is the anglec of rotation.
According to conception of the present utility model, can constitute the following example:
1, satisfies 90 °＜β＜135 ° simultaneously, the jaw crusher (see figure 1) of the negative supporting of-50≤H≤50mm, low suspended structure.
2, under the condition of being satisfied with embodiment 1, its fixedly the fastening bolt 4 of sewing jaw 3 be positioned at the top (see figure 1) of moving jaw dead eye.
3, under the condition of drive line angle β or the discontented sufficient embodiment 1 of moving jaw suspension height H, can fix above moving jaw dead eye with lag bolt behind sewing jaw 3 lengthenings.Can reach the service life of the moving jaw of protection, prolongation jaw like this.
Manufactured experimently a PE-400 single toggle jaw crusher according to embodiment 2, its drive line angle β is 110 °, and moving jaw suspension height is 0mm, and upper and lower slideway adopts not processing structure.This model machine has carried out Performance Detection in March, 1989 at Hebei province's mining machinery quality monitoring measuring station, and productivity ratio improves more than 50%, reaches 45m
3/ h, power consumption reduces more than 20%, is 0.67KWh/t, and the jaw life-span is improved 2 times, and its life-span is 300h, and the ratio of reduction is 10.
The utility model has the advantages that moving jaw movement characteristic coefficient is reduced to below 1; productivity ratio improves more than 20%; the jaw life-span improves more than 2 times; the product granularity characteristic is good, simultaneously can be energy-conservation about 20%, in addition; fixedly the fastening bolt of sewing jaw is positioned at moving jaw dead eye top; make the sewing jaw easy accessibility, be difficult for becoming flexible, and moving jaw is had protective effect.
Claims (3)
1, a kind of novel single toggle jaw crusher of being made up of frame, fixed jaw, sewing jaw, moving jaw, eccentric shaft and bracket is characterized in that:
A, bracket 7 adopt negative supporting structure form, and promptly the scope of drive line angle is: 90 °＜β＜135 °,
The scope of the suspension height H of b, moving jaw is :-50≤H≤50mm.
