Abstract
The invention relates to a screen plate pressing strip for protecting bolts and nuts of a vibrating screen. The pressing strip comprises a polyurethane (PU) pressing plate (1) and a PU gland (2), wherein the pressing plate (1) is provided with counter bores (8) provided with bolts; wedge-shaped annular grooves (5) are arranged on the inside circumferences of the counter bores (8); the gland (2) is hollow; the hollow size adapts to the bolts and nuts of a compression vibrating screen; wedge-shaped annular wing processes (6) are arranged on the outside circumference of the gland (2); the external diameter of the gland (2) is matched with the counter bores (8) on the pressing plate (1); and the wedge-shaped annular wing processes (6) on the gland (2) are matched with the wedge-shaped annular grooves (5) in the counter bores (8) on the pressing plate. The pressing strip can effectively protect the bolts and nuts on the screen pressing plate from being worn and eroded.
Description
Technical field
The present invention relates to a kind of device of protecting vibratory sieve bolt and nut, especially protect the sieve plate press strip of vibratory sieve bolt and nut.
Background technology
It is most for bolt compresses that vibratory sieve is pressed the mode of sieve plate at present, and this bolt compresses mode makes bolt head and nut exceed sieve plate, expose outside, in use; The oversize material constantly rubs, corrodes exposed bolt and nut; Very easily cause the distortion of destruction and nut and the bolt rust of bolt silk tooth dead, this just gives demounting bolt and changes sieve plate and bring great difficulty, sometimes even have to take the way of gas cutting; Both increased the working time, also brought certain damage to sieve plate.
Summary of the invention
The sieve plate press strip that the purpose of this invention is to provide a kind of vibratory sieve is able to protect effectively the bolt of pressing sieve plate and nut is not frayed and the effect of erosion.
For realizing above-mentioned purpose, the present invention protects the sieve plate press strip of vibratory sieve bolt, nut to be made up of polyurethane pressing plate, polyurethane gland, has the counterbore of construction bolt on the polyurethane pressing plate, and counterbore inside circumference place is provided with the wedge shape annular ditch groove; The polyurethane gland is a hollow type, and interior empty size adapts with the bolt, the nut that compress vibratory sieve, and it is prominent that the gland outer circumference is provided with wedge shape ring-type wing; The gland external diameter cooperates with counterbore on the pressing plate, and the wedge shape ring-type wing on the gland is prominent to be cooperated with the interior wedge shape annular ditch groove of pressing plate counterbore.
In the prominent wedge shape annular ditch groove that embeds in the pressing plate counterbore of wedge shape ring-type wing on the gland, closely cooperate, form the space of a sealing bolt and nut; Even sieve nest high frequency large-amplitude vibration; Gland can not come off yet, and has both avoided the oversize material that screw bolt and nut is rubbed, and anti-again sealing and other medium contact with screw bolt and nut; Thereby the screw bolt and nut that makes the pressure sieve plate is not worn and corrodes, and has protected effectively and has pressed the screw bolt and nut of sieve plate injury-free.
Description of drawings
Fig. 1 is a longitudinal sectional view of the present invention.
Fig. 2 is a transverse sectional view of the present invention shown in Figure 1.
Fig. 3 is the cutaway view of the pressing plate among Fig. 1.
Fig. 4 is the cutaway view of the gland among Fig. 1.
The specific embodiment
The present invention will be described below in conjunction with accompanying drawing and embodiment.
Like Fig. 1, Fig. 2, shown in Figure 3, the present invention forms (convenient for describing, hereinafter to be referred as pressing plate, gland) by polyurethane pressing plate 1, polyurethane gland 2, offers the counterbore 8 of some construction bolts on the pressing plate 1, is provided with wedge shape annular ditch groove 5 at the inside circumference place of counterbore 8.Like Fig. 1, Fig. 2, shown in Figure 4, gland 2 is a hollow type, and interior empty size adapts with the bolt 3, the nut 4 that compress vibratory sieve, on gland 2 outer circumference, is provided with wedge shape ring-type wing prominent 6.Like Fig. 1, shown in Figure 2, gland 2 external diameters cooperate with counterbore 8 on the pressing plate 1, and the wedge shape ring-type wing on the gland 2 prominent 6 cooperates with pressing plate counterbore 8 interior wedge shape annular ditch grooves 5.
As improvement of the present invention, in pressing plate, be provided with steel plate 7, with the intensity that increases pressing plate, the applying degree that improves pressing plate and screen cloth.
The present invention makes simply, easy installation and removal.Use vibratory sieve compass screen surface of the present invention smooth, attractive in appearance.
