Technical Field

The utility model relates to a building material processing technology field, more specifically say and relate to a shale shaker.

Background

Along with the rapid development of economy in China, the building scale is larger and larger, the demand of concrete used for buildings is larger and larger, and the concrete is also called concrete and is one of the most important civil engineering materials in the present generation. It is made up by using cementing material, aggregate and water according to a certain proportion through the processes of mixing, vibrating, forming and curing under a certain condition. The concrete has the characteristics of rich raw materials, low price and simple production process, so the using amount is larger and larger, meanwhile, the concrete also has the advantages of high compressive strength, good durability, wide strength grade range and wide use range, and the concrete is used in various civil engineering, namely shipbuilding industry, mechanical industry, ocean development, geothermal engineering and the like and is also an important material.

In the production process of concrete for buildings, the requirement on the particle size of aggregates is certain, and the requirements on the particle size of the aggregates for concrete in different application scenes, such as the requirement on the particle size of the aggregates for the concrete for manufacturing water permeable bricks, are different. In concrete production, river sand is generally used as aggregate, but at present, the mining of river sand is forbidden by the nation, and stone is generally crushed into fine particles to replace the river sand as the aggregate of concrete. However, the aggregate has uneven particle size, and the aggregate with larger particle size often exists, and the performance of the concrete is affected after the aggregate is mixed into the concrete, so that the aggregate needs to be screened before being mixed into the cementing material and mixed with the cementing material, and the aggregate with larger particle size is screened out, so that the aggregate meeting the production requirement of the concrete is left.

Screening of the aggregates is generally achieved by means of vibrating screens. The existing vibrating screen generally comprises a storage bin, a screen is arranged in the storage bin, the screen is connected with a vibrating motor, and oscillating power is provided for the screen so as to complete screening of aggregates. The existing vibrating screen structure is generally characterized in that a screen is horizontally arranged in a storage bin, and the existing vibrating screen structure is cleaned in a manual mode, so that the cleaning efficiency is low.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects and shortcomings in the prior art, the application provides the vibrating screen, and aims to solve the problem of automatic cleaning of large-particle-size aggregates left on a screen of the vibrating screen. This application sets up the screen cloth slope in the feed bin to link to each other screen cloth and vibrating motor, when the screening volume for preventing the aggregate is great simultaneously, the screen cloth roll-off that the aggregate that is not screened set up along the slope still is provided with the striker plate in the one end of screen cloth, and the setting of striker plate can prevent effectively that the aggregate that is not screened from the screen cloth roll-off, ensures that the aggregate that clears up all is the aggregate that can not pass through the screen cloth sieve mesh. The technical scheme of this application can effectively improve aggregate screening efficiency, can accomplish the automatic clearance of big particle size aggregate, avoids big particle size aggregate to plug up the sieve mesh of screen cloth.

2. When the material of quilt conveying is more, when piling up in the feed bin, do not prevent that the less aggregate of particle diameter from not in time spilling from the sieve mesh of screen cloth and just removing material export exhaust phenomenon from the sieve and appear, this application still is provided with the striker plate in the top of the decurrent one end of screen cloth slope, the effect of striker plate is that block more aggregate, and only a small amount of aggregate can pass through from the aggregate passing through between striker plate and the screen cloth, and this part aggregate is after passing through the passing through mouth, is sieved on the screen cloth before removing the material export promptly in the baffle below, and the aggregate that the particle diameter is little passes through the sieve mesh and leaks down, and the aggregate that the particle diameter is great can not pass through the sieve mesh then removes the material export discharge from the. According to the aggregate screening device, aggregates can be blocked by adding the striker plate, when more aggregates are prevented, the aggregates are discharged from the screening material outlet without being screened completely, the amount of the aggregates passing through the through hole is limited by the striker plate, screening is carried out at the screen below the striker plate, the screening rate can be ensured, and the aggregates which can pass through the screen hole are not discharged from the screening material outlet; meanwhile, the screen mesh part on one side of the upper end of the material baffle plate can still normally complete screening work. The utility model provides a shale shaker, screening efficiency is high, the screening rate is high, the condition of leaking the sieve can not appear, ensures that the aggregate that removes material export exhaust from the sieve all is the aggregate that can not pass through the sieve mesh.

3. The inclination direction of the striker plate is different from that of the screen mesh, so that normal blanking of aggregate above the screen mesh is facilitated. The automatic discharge of the aggregates with large particle sizes which can not pass through the sieve pores can be realized, and the aggregates with large particle sizes are prevented from blocking the sieve pores. In this application, vibrating motor direct action has strengthened the vibration of screen cloth, improves vibration frequency, also further prevents that large granule diameter aggregate card from in the sieve mesh.

4. This application sets up the motor cover on vibrating motor, is for protecting vibrating motor, prevents that the aggregate from producing the influence to vibrating motor, influences vibrating motor's normal work, influences vibrating motor's life. Still install the spring under the four corners of screen cloth in this application, set up the screen cloth through the spring, under vibrating motor's effect, deformation takes place for the spring, also provides the vibration for the screen cloth, further improves the vibration frequency of screen cloth, prevents that the sieve mesh from being blockked up.

5. The utility model provides a be provided with the small opening on the fixed plate of fixed mounting spring, its purpose provides the support for the installation of spring, and the effect of small opening is to spill from the aggregate that leaks under the screen cloth, prevents to pile up on the aggregate re-fixing plate, causes the influence to the spring.
