Construction Sand Screening Device

Abstract

The invention discloses a building sand sieving device and mainly relates to the field of building equipment. The building sand sieving device comprises a vehicle body, a transmission device assembly,a sand screen plate and a sand storage table. The transmission device assembly comprises a left power device assembly, a right power device assembly and a sheave driving device assembly. The sheave driving device assembly comprises a supporting slat, a gear set, a left sheave shifting device, a right sheave shifting device and a middle sheave. The left sheave shifting device and the right sheaveshifting device each comprise a fixed shaft, a shifting rod, a shifting pin and a convex locking arc, wherein each shifting pin is arranged at the end of the corresponding shifting rod. A central shaft is arranged in the center of the middle sheave. The top of the central shaft penetrates through the transmission box and is connected with the sand screen plate. The building sand sieving device hasthe beneficial effects that sand obtained after sand sieving can be temporarily stored, so that the construction efficiency is greatly improved; screens with different meshes can be replaced according to purposes; and the device can be driven by two motors, so that the problem that the service life of a motor is shortened due to the long-term high-load operation of the motor during driving by onemotor can be avoided.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a construction sand screening device. Background technique [0002] Sand is an essential basic raw material in the field of construction. There are many impurities in the sand, such as gravel, garbage, etc., and the sand in the sand is also divided into different grades for different purposes. The required sand particle size grade different. Therefore, it is necessary to sieve the sand before using it. The sand screening machine in the prior art is inconvenient to replace the screens with different meshes according to the purpose, and the sand after the sand screening can only be poured on the ground, and then manually shoveled into the cart or filled with sand when in use The sand buckets and sandbags are transported to the corresponding construction stations for use, which greatly reduces the construction efficiency; and the existing sand screening machine is driven by o...
