Abstract

The utility model relates to a material screening machine, in particular to a screening plate provided with size-adjustable screening holes and utilizing the size and figure of the screening holes to classify the material according to the particle sizes. The screening plate comprises two screening plates, wherein the upper screening holes and the lower screening holes are evenly distributed on an upper screening plate and a lower screening plate, which are closely attached on each other, only the hole gap between the upper screening hole and the lower screening hole is visible; the upper cross bolt holes and lower cross bolt holes which are matched one by one are arranged at the both sides of the upper screening plate and the lower screening plate to stagger the upper screening holes and the lower screening holes matched one by one on the upper screening plate and lower screening plate respectively, thereby changing the hole positions and hole gaps. The utility model can simply adjust the positions of the upper and lower screening plate to realize the change of screening hole figure and diameter to realize the purpose of multi-function, and the labor, material and energy is saved.

Description

Can adjust the sieve plate of slot size

Technical field

The utility model relates to material screening machinery, refers in particular to utilize different apertures of sieve plate and shape material to be divided into the sieve plate of the slot size adjusted of granular size different stage.

Background technology

In people's production, life, often needing that some article is pressed the difference of variable grain size uses, as at rice, flour, breeze, stone etc., this type of screening class is very thin, workload is big, so screen cloth sieve plate demand is also big, but owing to be with the principle of a kind of sieve plate screen cloth screening: greater than the material of hole diameter of sieve (perforated) plate on the sieve plate upper strata, material less than sieve aperture falls from sieve aperture and sieves, so the screen(ing) machine in each aperture can only sieve the material of a certain particle, if the transform particle size just must be changed another kind of sieve plate, the expense of taking a lot of work material, tangible trouble.

Summary of the invention

The purpose of this utility model is improved and is innovated at the shortcoming that exists in the background technology and problem, provides a kind of technology advanced person, especially the sieve plate of the Shi Yong slot size adjusted.

The technical scheme that realizes the utility model purpose is: sieve plate is formed by two, wherein upper sieve plate and play sieve aperture and the following sieve aperture of being evenly equipped with above the sieve plate, upper sieve plate and following sieve plate are close together, only make and be visible hole between sieve aperture and the following sieve aperture, the both sides of upper sieve plate and following sieve plate are provided with goes up cross bolt hole and following cross bolt hole one to one, be used for staggering with following sieve aperture, the position, hole and the hole that are superimposed are changed going up one to one sieve aperture on upper sieve plate and the following sieve plate.

The utility model can be realized the change in sieve aperture shape and aperture in the sieve plate position up and down by simple adjustment, realizes a tractor serves several purposes, labor and material saving, energy-conservation practicality.

The specific embodiment

By Fig. 1,2 as can be known, the utility model sieve plate is formed by two, upper sieve plate (1) and be evenly equipped with sieve aperture (11) and following sieve aperture (21) above the following sieve plate (2) wherein, upper sieve plate (1) and following sieve plate (2) are close together, only make and be visible hole between sieve aperture (11) and the following sieve aperture (21), the both sides of upper sieve plate (1) and following sieve plate (2) are provided with goes up cross bolt hole (12) and following cross bolt hole (22) one to one, be used for and go up sieve aperture (11) one to one on upper sieve plate (1) and the following sieve plate (2) and following sieve aperture (21) staggers, the position, hole and the hole that are superimposed are changed.

The pass of upward sieve aperture (11) described in the utility model and following sieve aperture (21) is with size and arrange consistent.Described upper sieve plate (1) and following sieve plate (2) are by last cross bolt hole (12) and cross bolt hole (22) can be from horizontal direction or vertical direction adjustment hole down.

The utility model is with two surperficial slot size unanimities, the sieve aperture spacing is the same, arranging consistent slotted hole sieve plate stack is installed on the same screen(ing) machine, fixed screw holes on the screen(ing) machine periphery is processed into cross shape, can make the dislocation arbitrarily up and down of two sieve plates thus, utilize stifled last slice the porose area of not punch area screening of sheet down, what that misplace to change the shape and the aperture of sieve aperture according to.

Embodiment described in the utility model only is the description that preferred implementation of the present utility model is carried out; be not that the utility model design and scope are limited; do not breaking away under the preceding topic of the utility model design philosophy; engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.

Claims

1, a kind of sieve plate of adjusting slot size, it is characterized in that sieve plate forms by two, upper sieve plate (1) and be evenly equipped with sieve aperture (11) and following sieve aperture (21) above the following sieve plate (2) wherein, upper sieve plate (1) and following sieve plate (2) are close together, only make and be visible hole between sieve aperture (11) and the following sieve aperture (21), the both sides of upper sieve plate (1) and following sieve plate (2) are provided with goes up cross bolt hole (12) and following cross bolt hole (22) one to one, be used for and go up sieve aperture (11) one to one on upper sieve plate (1) and the following sieve plate (2) and following sieve aperture (21) staggers, the position, hole and the hole that are superimposed are changed.

2, the sieve plate of adjusting slot size according to claim 1 is characterized in that the pass of described upward sieve aperture (11) and following sieve aperture (21) is consistent with size and arrangement.
