Screening equipment capable of pre-weighing and used for screening concrete raw materials

Abstract

The screening equipment comprises a screening machine and a protective cover, the protective cover is located on the right side of the screening machine, two limiting plates are fixedly connected to the right side of the screening machine, and clamping grooves are formed in the right sides of the limiting plates. Through cooperative use of the screening machine, the protective cover, the limiting plate, a clamping groove, a fixing block, a fixing groove, a positioning mechanism and an adjusting mechanism, the adjusting mechanism is pulled to drive the positioning mechanism to enter the fixing groove, and at the moment, the protective cover can be detached to maintain the interior of the protective cover; after the concrete screening is completed, the concrete screening device is assembled, the adjusting mechanism is pulled in the opposite direction, the limiting plate is fixed through cooperation with the positioning mechanism, a large amount of dust and other impurities can be generated in the concrete screening process, a transmission belt wheel can be damaged, and therefore the transmission belt wheel needs to be protected, and the situation that use is affected after damage occurs is avoided.

Description

technical field [0001] The invention belongs to the technical field of screening equipment, and in particular relates to a screening equipment for screening concrete raw materials that can be weighed in advance. Background technique [0002] The screening equipment screens and distinguishes raw materials through vibration, which can be used to screen concrete raw materials, and distinguish suitable raw materials through machine vibration, thereby improving the quality of concrete to meet the use requirements. At the same time, in the screening process The raw materials can be weighed, but the problem in the existing technology is that a large amount of dust and other impurities will be generated in the process of screening concrete, which will cause damage to the transmission pulley, so it needs to be protected to avoid damage and affect the use . Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a pre-weig...
