Sand screening machine for indoor decoration

Abstract

The invention discloses a sand screening machine for indoor decoration and mainly relates to the field of building equipment. The sand screening machine comprises a rack, wherein a feed hopper is arranged at the top of the rack; a first sand screening box of which the upper and lower ends are opened is arranged on the lower side of the feed hopper; a second sand screening box of which the upper and lower ends are opened is arranged on the lower side of the first sand screening box; a first connecting rod is arranged at the rear end of the top of the second sand screening box; one end of the first connecting rod is hinged with the second sand screening box, and the other end of the first connecting rod is hinged with the first sand screening box; a second connecting rod is arranged at the front end of the bottom of the second sand screening box; one end of the second connecting rod is hinged with the second sand screening box, and the other end of the second connecting rod is hinged with a crank; an inclined chute is formed in the lower side of the second sand screening box. The sand screening machine disclosed by the invention has the beneficial effects that two-stage screening canbe performed, the two-stage screening can be driven to simultaneously start by drive equipment, and the energy consumption can be reduced. Moreover, manual driving can be performed in an unpowered state, and various requirements of indoor decoration can be met.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a sand screening machine for interior decoration. Background technique [0002] In interior decoration, various types of sand are needed. Coarse sand, medium sand, and fine sand all have their corresponding uses. When preparing materials, only coarse sand is usually prepared. When using, they should be screened according to needs. At present, Screens are often used for manual screening, which has a large workload and low efficiency. However, some existing electric sand screening machines cannot operate without electricity, and often use first-level screening, which requires multiple screenings to meet the use requirements. However, some devices that can perform multi-level screening require multiple driving devices, which consume a lot of power. In the actual decoration process, in order to meet the deadline, sometimes the floor and walls are decorated before the building is...

[0002] In interior decoration, various types of sand are needed. Coarse sand, medium sand, and fine sand all have their corresponding uses. When preparing materials, only coarse sand is usually prepared. When using, they should be screened according to needs. At present, Screens are often used for manual screening, which has a large workload and low efficiency. However, some existing electric sand screening machines cannot operate without electricity, and often use first-level screening, which requires multiple screenings to meet the use requirements. However, some devices that can perform multi-level screening require multiple driving devices, which consume a lot of power. In the actual decoration process, in order to meet the deadline, sometimes the floor and walls are decorated before the building is officially powered on. Some electric sand screening machines are completely unusable, and it is difficult to meet the needs of this situation
