Abstract
The invention discloses a support of a grid plate screen, and aims to provide the support of the grid plate screen which has long service life of a rubber spring and high vibration coal screening efficiency. The invention has the technical scheme that: the support of the grid plate screen comprises a grid plate and the rubber spring; a rigid support body is arranged on one side of the rubber spring between the grid plate and a foundation; and the height of the rigid support body is lower than that of the rubber spring. According to the support of the grid plate screen, the height of the rigid support body is lower than that of the rubber spring and is more than or equal to the deformation of the rubber spring under the total weight of the weight of the grid plate and that of a coal car. The support of the grid plate screen is used for supporting the grid plate screen.
Description
Technical field:
The present invention relates to a kind of vibratory sieve, particularly a kind of support of grate plate sieve.
Background technology:
The support of existing grate plate sieve is a uniform rubber spring between grate plate and basis, when the vehicle of fully loaded coal is parked on the grate plate, the weight maximum that grate plate is carried, and coal onboard is discharged to that vehicle promptly leaves grate plate on the grate plate, and the vibration of the coal that vibrator work will not leaked down this moment by grate plate makes it to fall on the conveyer belt of grate plate below and be transferred away.When coal car entered on the grate plate in this year, owing to the weight of weight much larger than contained coal, and the bearing capacity of rubber spring was lower, should increase rubber spring, otherwise rubber spring is impaired, has satisfied the rubber spring of the weight of car and coal, but can reduce the vibration of grate plate and the efficient of screening coal.
Summary of the invention:
The purpose of this invention is to provide the screen coal support of the high a kind of grate plate sieve of efficient of a kind of rubber spring long service life and vibration.Technical scheme of the present invention is, a kind of support of grate plate sieve comprises grate plate and rubber spring, and it is characterized in that: a side of the rubber spring between grate plate and basis is provided with rigid support, and the height of this rigid support is lower than the height of rubber spring.The support of a kind of grate plate sieve is characterized in that: the height of described rigid support is lower than the deflection of amount 〉=rubber spring under the gross weight of the weight of grate plate and coal conveyor own wt of the height of rubber spring.The present invention has rubber spring long service life and the high advantage of screening efficiency compared with the prior art.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
In conjunction with above accompanying drawing the present invention is elaborated, one side of the rubber spring 1 that is provided with between grate plate 4 and basis 3 is provided with rigid support 2, the height of this rigid support is lower than the height of rubber spring, the numerical value that both highly differ is determined by following requirement: according to the own wt of conventional coal conveyor and the weight of grate plate rubber spring is set, the deflection of rubber spring is A under the weight of coal conveyor self and grate plate weight, and the value that rigid support is lower than the rubber spring height equals A or is slightly larger than A.
This combined support that rigid support and resiliency supported are arranged, when carrying coal car and entering on the grate plate, rubber spring is compressed the back grate plate and is pressed on the rigid support piece, this moment, rubber spring promptly can excessive deformation, thereby its life-span can not shorten, when coal conveyor left grate plate, grate plate did not contact with rigid support, thereby sieve unaffected, the screening efficiency height.
Claims (2)
1. the support of a grate plate sieve comprises grate plate and rubber spring, and it is characterized in that: a side of the rubber spring between grate plate and basis is provided with rigid support, and the height of this rigid support is lower than the height of rubber spring.
2. the support of a kind of grate plate sieve as claimed in claim 1 is characterized in that: the height of described rigid support is lower than the deflection of amount 〉=rubber spring under the gross weight of the weight of grate plate and coal conveyor own wt of the height of rubber spring.
