Concrete sand screening device

Abstract

The utility model discloses a concrete sand screening device, which specifically relates to the technical field of concrete sand screening, comprises a bottom plate, and a spiral feeder rotates to facilitate the transportation of concrete sand. At the same time, the concrete sand can be broken up during the rotation to prevent the wet concrete sand from agglomerating. At the same time, a heating ring is used to heat the sand placed in a cylinder to reduce the viscosity of the sand, so as to help quickly break it up and facilitate the subsequent screening. When the bevel gear one rotates, the bevel gear two will be driven to rotate, and then the cam will be driven to rotate. When the cam and the screen are in contact with each other, the screen is pushed to move upward. When the cam and the screen are not in contact, the screen can be pulled to vibrate under the influence of the elastic force of the spring, so that the concrete sand on the screen can be screened, and the coarser sand will fall into the second drawer along with the inclined screen, and the finer sand will fall into the first drawer through the screen, so that the sand can be screened conveniently, and the screen can be replaced or cleaned in time.

Description

Technical Field

[0001] The utility model relates to the technical field of concrete sand material screening, in particular to a concrete sand material screening device. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering.

[0003] A Chinese patent with announcement number CN219273607U discloses a concrete sand screening mechanism. Through the designed cleaning mechanism, the original screening mechanism is improved. After the sand is screened, during the cleaning process, it is necessary to brush off the dust on the surface of the rolling barrel with a brush, and in addition, the rolling barrel is cleaned by flushing it with a water pipe. During the cleaning process, it is necessary to clean it manually, which is inconvenient to operate. After the screening mechanism is used, the cleaning mechanism is connected to the cleaning mechanism through an external water pipe, and the rolling barrel is automatically flushed to complete the cleaning operation after the screening mechanism is used, thereby increasing the convenience of the screening mechanism when in use.

[0004] However, in the above scheme, the concrete sand is directly screened, but the sand will clump due to moisture during screening. Direct screening will directly screen out the agglomerated sand, and the coarse sand and fine sand in the agglomerates cannot be screened, affecting the screening effect.

[0005] Therefore, it is necessary to invent a concrete sand material screening device. Utility Model Content
