Abstract
The utility model discloses a support for a grate plate screen, and aims to provide a support for a grate plate screen, which is long in service life of a rubber spring and high in vibratory coal screening efficiency. The technical scheme includes that the support for the grate plate screen comprises a grate plate and the rubber spring, a rigid support body is arranged on one side of the rubber spring between the grate plate and a base, the rigid support body is lower than the rubber spring, and the height difference between the rigid support body and the rubber spring is larger than or equal to deflections caused by the sum of the weight of the rubber spring on the grate plate and the self-weight of a coal car. Besides, the support is used for supporting the grate plate screen.
Description
Technical field:
The utility model 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 between grate plate and basis, to be uniformly distributed with rubber spring; When the vehicle of fully loaded coal is parked on the grate plate; The weight that the grate plate is carried is maximum; And coal onboard is discharged to that vehicle promptly leaves the grate plate on the grate plate, and the vibration of the coal that vibrator work will not leaked down this moment through the grate plate makes it to fall on the conveyer belt of grate plate below and be transferred away.When coal car got 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 the utility model provides 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.The technical scheme of the utility model 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 said 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 utility model and prior art relatively have rubber spring long service life and the high advantage of screening efficiency.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
In conjunction with above accompanying drawing the utility model is elaborated; One side of the rubber spring 1 that between grate plate 4 and basis 3, is provided with 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 confirmed 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 on the coal car entering grate plate, rubber spring is compressed 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 the grate plate, the grate plate did not contact with rigid support; Thereby sieve unaffectedly, screening efficiency is high.
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 said 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.
