Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a double-layer linear vibrating screen. Background Art

[0002] Vibrating screen is a screening equipment, mainly used for grading and screening of solid materials. It can generate vibration through the vibration motor to make the material on the screen surface jump and slide, thereby realizing material screening. Compared with the single-layer linear vibrating screen, the double-layer linear vibrating screen has an extra layer of screen, which can grade the material into three layers and can handle the situation of mixing materials of three finenesses, so it is widely used in the grading and screening of granular materials.

[0003] When using the existing double-layer linear vibrating screen, the material is generally placed on one end of the screen first, and the screen is driven to vibrate by a vibration motor, so that the material slides to the other end while vibrating. During the sliding process, the material is screened by two layers of screens, so that three different sizes of material particles flow out at the other end. However, when feeding the screen, the bagged material is generally poured directly onto the screen, or shoveled directly onto the screen with a shovel. The uneven feeding can easily lead to the appearance of piles of material on the screen. The screening effect is poor in places where the material is denser, and the utilization rate is low in places where the material is less. For this reason, we provide a double-layer linear vibrating screen to solve the above problems. Utility Model Content

[0014] 3) Beneficial effects:

[0015] Compared with the prior art, the double-layer linear vibrating screen has the following beneficial effects:

[0016] 1. The utility model sets components such as rotating rollers and adjusting plates. The rotating roller drives the extrusion plate on its upper part to extrude the material, so that the material falls to the lower part of the rotating roller, thereby completing the material discharge. The position of the adjusting plate is adjusted to control the falling speed of the material, thereby achieving the effect of adjusting the material discharge speed. The material falls at a certain rate and will not fall in piles, achieving the effect of uniform material discharge, thereby solving the problems of uneven material discharge in the existing screen, which easily leads to the piles of materials on the screen, poor screening effect in places where the materials are dense, and low utilization rate in places where the materials are less.

[0017] 2. The utility model sets an adjustment mechanism and other components, and the two telescopic rods are shortened at the same time, driving the round rod to move downward. The round rod drives the fixed plate to move downward through the fixed block, thereby driving one end of the support plate to move downward, causing the filter to tilt, thereby achieving the effect of adjusting the inclination of the filter, thereby controlling the speed of the material flowing to the discharge port. When the material moves slowly, the screening quality is higher, and when it moves faster, the efficiency is higher. It is suitable for different types of materials and achieves the effect of increasing applicability. BRIEF DESCRIPTION OF THE DRAWINGS

There are two limiting plates 10, and the adjacent sides of the two limiting plates 10 are slidably connected to the adjusting plate 5.
