Abstract

The utility model provides a piece of movable mixture screening equipment, solving the problem that currently to-be-screened raw materials need to be conveyed to remote fixed screening production lines. The movable mixture screening equipment comprises a vibrating-screen extension set, consisting of a screen mesh, a screen box, a vibration exciter and an electric motor. A metal support framework is disposed below the vibrating-screen extension set. The vibrating-screen extension set is seated on the metal support framework via four spring assemblies, each of which is composed of an upper base, a lower base, a large spring and a small spring. A downwardly-inclined screen blanking slide plate is fixed below the screen box and in the metal support framework and is oriented beyond the metal support framework. A movable steel plate is welded at the bottom of the metal support framework. The movable mixture screening equipment of the utility model allows in-situ screening production at one side of to-be-screened raw material storage yards, and is capable of integrally moving according to the screening production demands.

Description

Removable compound screening plant

Technical field

The utility model relates to a kind of screening plant, relates in particular to a kind of removable compound screening plant.

Background technology

Be fixed on vibratory sieve technology and the screening plant of producing the rubble machining production line, extensively use in various places.Its weak point: the screening raw material needs to transport to gravity flow screen at a distance from the material storage yard entrucking and divides the production line feeding mouth, and the finished product building stones after the processing land, refill the car outward transport through belt conveyor Ji Dui.

Summary of the invention

The purpose of the utility model is the problems referred to above to existing gravity flow screen subset existence; Provide a kind of and can carry out scene screening production in screening material storage yard one side; Solve the screening raw material and be transported to the contradiction that gravity flow screen divides production line at a distance, and need the whole removable compound screening plant that moves according to screening production.

The purpose of the utility model is achieved in that the removable compound screening plant involving vibrations screening machine of the utility model; Said vibrating screen classifier comprises screen cloth, screen box, vibrator and motor; Below said vibrating screen classifier, also be provided with metal and support framework; Vibrating screen classifier is located in metal through four groups of springs and supports that each groups of springs is made up of top base, bottom base and big spring, little spring on the framework, and top base, bottom base support that with vibrating screen classifier, metal framework is fixed together respectively; Big spring is installed between top base and the bottom base, and little spring is positioned at big spring; At the minus mesh slide plate that also is fixed with below the said screen box, in metal is supported framework outside downward-sloping and the guiding metal support framework; Support the bottom of framework to be welded with moving steel plate at said metal.

As preferred version, said vibrator is installed on the side plate of screen box, and vibrator adopts eccentric block as exciting force, and exciting force is strong, and the eccentric shaft of vibrator and motor adopt shaft coupling to connect, flexibly jointed chain, and running is steadily.

The technique effect of the utility model is:

1, realizes that in screening material storage yard one side screening raw material (native stone compound) sieves on the spot, produce continuously, and reach the purpose of conservation long-distance transportation expense.

2, metal supports the framework bottom to be welded with moving steel plate, and this equipment can effectively reduce in process of production beats, and can need according to screening production, and integral body moves removable compound screening plant.

3, each newly-increased vibration damping little spring in every group of spring makes the vibrating screen classifier effectiveness in vibration suppression of opening, stop obvious.

4, metal supports to install in the framework minus mesh sliding steel plate, and minus mesh slides to metal thus and supports to use the shovel loader entrucking outside the framework, reaches the vibrating screen classifier continuous operation, increases screening output.Increase the weight of metal support framework simultaneously, strengthened the stability of this equipment screening operation.

Description of drawings

Fig. 1 is the front elevation view of embodiment.

Fig. 2 is the A-A elevation of Fig. 1.

The specific embodiment

Referring to Fig. 1 and Fig. 2, the screening plant involving vibrations screening machine of present embodiment and metal are supported these two parts up and down of framework 4; Said vibrating screen classifier comprises screen cloth (not shown), screen box 1, vibrator 8 and motor, and screen cloth adopts one deck sieves, and the structure of screen cloth and screen box 1 is a prior art, does not detail at this; In the both sides of screen box 1 a cover vibrator 8 and a motor is installed all, the bearing of vibrator 8 adopts high-strength bolt to be installed on the side plate of screen box 1, and vibrator 8 adopts eccentric block as exciting force, and the eccentric shaft of vibrator 8 and motor adopt saddle type shaft coupling to connect.Motor rotates, and the eccentric shaft that drives vibrator 8 through saddle type shaft coupling rotates, and produces centrifugal intertia force, forces screen cloth and screen box 1 vibration.

Referring to Fig. 1 and Fig. 2; Metal supports framework 4 to be located at the below of vibrating screen classifier, and metal supports framework 4 to adopt the shaped steel of super large, increases the weight that metal is supported framework; Be enough to support the vibrating screen classifier normal screen to divide the stability of producing; Metal supports that framework 4 is welded to form by four columns and truss, and four columns adopt the square steel of 200 * 200mm, and truss adopts I-steel and the channel-section steel of 180-250mm; Vibrating screen classifier is located in metal through four groups of springs 2 and supports on the framework 4; Each groups of springs 2 is made up of top base 201, bottom base 202 and big spring 9, little spring (not shown); Top base 201, bottom base 202 support that with vibrating screen classifier, metal framework 4 is fixed together respectively; Big spring 9 is installed between top base 201 and the bottom base 202, and little spring is positioned at big spring 9, and little spring can increase damping effect; At the minus mesh slide plate 6 that also is fixed with below the screen box 1, in metal is supported framework 4 outside downward-sloping miter angle and the guiding metal support framework 4; Below the bottom of the both sides of minus mesh slide plate 6 and minus mesh slide plate 6, be fixed with

discharge flapper

31 and 32; Above minus mesh slide plate 6 tops, in the bottom of screen box 1, also be provided with downward-sloping and be directed at the slide plate 7 at minus mesh slide plate 6 tops, minus mesh slides to metal by the slide plate 7 of screen box 1 with minus mesh slide plate 6 and supports outside the framework 4; Support the bottom of framework 4 to be welded with the thick moving steel plate of 10mm 5 at metal, and be furnished with the steel wire cable that confession is moved, do the movable accessory of screening plant, screening plant can be dragged by the excavator cooperation, and the success that reaches entire equipment is moved.
