Abstract
The utility model relates to a screening machine, particularly a double-beam screen, and is suitable for the screen operation in the industries such as the coal mine industry, the power industry, the building materials industry, and the like. The screening machine comprises a screen box, screen plates, a support leg, double vibrating beams, two groups of vibration exciters, a shaft coupling and motors, wherein, the double vibrating beams are mounted at the bottom part of the screen box; the vibration exciters are mounted on the two sides of the double vibrating beams; the screen box which is supported by a spring is mounted on the support leg; the screen plates are fixed on the screen box; two motors drive the vibration exciter of the two sides thereof to rotate and vibrate through the shaft coupling respectively; the exciting force generated by the inertia vibration exciters at the two ends is counteracted along the vibrating beam direction; only the force perpendicular to the direction of the double vibrating beams and the screen plates is superposed, and then the superposed force is transmitted to the material on the screen plates and an underframe under the screen box; and the impact force to the underframe is reduced by the isolation spring. Therefore, when the material passes along the screen plates with a certain inclined angle, the screen plate can play a screening function on material.
Description
Technical field
The utility model relates to a kind of sieving machine, and a kind of specifically twin beams sieves, and is applicable to the screening operation of industries such as colliery, electric power, building materials and metallurgy.
Background technology
Existing vibratory sieve is generally dual-sided board, side plate adopts the pipe beam to connect, vibrator is installed on the side plate, this structural limitations vibratory sieve to the development of maximizing, the power of large scale vibratory sieve, weight and vibration stress all sharply increase, structural strength and rigidity to vibratory sieve all have very high requirement, and common sieving machine structure has been difficult to satisfy this requirement.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art part, provide a kind of simple in structure, big sieving area, vibration evenly, the twin beams sieve that production efficiency is high.It comprises screen box, sieve plate, supporting leg, two walking beam, two groups of vibrators, shaft coupling and motor.Two walking beams are installed on the bottom of screen box, two groups of vibrators are installed on the both sides of two walking beams, screen box is installed on the supporting leg, support by spring, the polylith sieve plate is fixed on the screen box, two motor drive both sides vibrator whirling vibration by shaft coupling respectively, according to the motor synchronizing principle of inertia, the exciting force that the two ends inertia vibration generator produces is cancelled out each other along the walking beam direction, only the power perpendicular to the direction of two walking beams and sieve plate superposes mutually, this power passes to material on the sieve plate and the underframe under the screen box, impulsive force to underframe reduces to impact by isolation spring, so when the sieve plate at certain angle of inclination, material edge passed through, sieve plate just can play the sieving actoion to material.
The utility model is realized with following technical scheme: a kind of twin beams sieve, it comprises screen box, be fixed with sieve plate on the screen box, the supporting leg that has spring is arranged below the screen box, there is motor in initial and end portion at the twin beams sieve, it is characterized in that: the bottom of screen box is equipped with two groups of two walking beams, use pipe beam rigid attachment between two walking beams, the both sides of two walking beams are equipped with vibrator, screen box is supported by the spring on the supporting leg, motor drives the vibrator whirling vibration of both sides respectively by shaft coupling, drives two walking beams, screen box and sieve plate body vibration.
Described vibrator is installed on two walking beam both sides respectively, adopts the power transmission shaft transmission between two vibrators of the every side on two walking beams.
Described polylith sieve plate is fixed on the screen box.
The utility model has the advantages that: adopt two walking beams to drive screen box, the sieve plate vibration, two walking beam structural strength height, good rigidity can make shaker vibration even, reduce the construction weight of side plate, cancelled interpleural Guan Liang, made complete machine weight saving, realized that vibratory sieve maximizes, reduce the oscillation intensity and the frame for movement requirement of strength of vibratory sieve, reduced the machine-building difficulty of sieve.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural representation:
Fig. 2 is the utility model structure side view:
Among the figure: 1, screen box, 2, supporting leg, 3, two walking beam, 4, vibrator, 5, power transmission shaft, 6, shaft coupling, 7, spring, 8, motor, 9, sieve plate.
The specific embodiment
As shown in the figure: a kind of twin beams sieve, it comprises screen box 1, be fixed with sieve plate 9 on the screen box, the supporting leg 2 that has spring 7 is arranged below the screen box, there is motor 8 in initial and end portion at the twin beams sieve, it is characterized in that: the bottom of screen box 1 is equipped with two groups of two walking beams 3, use pipe beam rigid attachment between two walking beams, the both sides of two walking beams are equipped with vibrator 4, screen box 1 is supported by the spring on the supporting leg 27, motor 8 drives the vibrator whirling vibration of both sides respectively by shaft coupling 6, drives two walking beams, screen box and sieve plate body vibration.
Described vibrator 4 is installed on two walking beam 3 both sides respectively, adopts power transmission shaft 5 transmissions between two vibrators 4 of the every side on two walking beams 3.
Described polylith sieve plate is fixed on the screen box.
During work: two motor drive both sides vibrator whirling vibration by shaft coupling respectively, according to synchronous principle of inertia, the exciting force that the two ends inertia vibration generator produces is cancelled out each other along the walking beam direction, only the power perpendicular to the direction of two walking beams and sieve plate superposes mutually, this power passes to material on the sieve plate and the underframe under the screen box, impulsive force to underframe reduces to impact by isolation spring, so when the sieve plate at certain angle of inclination, material edge passed through, sieve plate just can play the sieving actoion to material.
