Adjustable inclined sand screening device for constructional engineering site construction

Abstract

The invention provides an adjustable inclined sand screening device for constructional engineering site construction. The device comprises a blowing sand fixing plate, a sand screening net and a finesand outflow plate, the bottom of the device body is arranged as a movable fixing platform, the blowing sand fixing plate is rotationally installed on the inner side of the top end of a supporting column, a secondary sand screening device is arranged on the upper side face of the blowing sand fixing plate, the sand screening net is fixed to the upper side of the blowing sand fixing plate through abolt, the fine sand outflow plate is arranged on the bottom side face of the blowing sand fixing plate, the bottom end of the blowing sand fixing plate is provided with a blowing sand angle adjustingdevice, and the bottom end of the blowing sand fixing plate is supported on the upper side face of the movable fixing platform through the blowing sand plate angle adjusting device. The adjustable inclined sand screening device for constructional engineering site construction is provided with the sand screening net which is detachably arranged, accordingly, the sand screening net can be rapidly replaced and repaired when damaged, and can be replaced according to the sand thickness degree, and the using effect of the device body is effectively improved.

Description

technical field [0001] The invention relates to the technical field of building construction auxiliary devices, in particular to an adjustable inclined sand screening device used for on-site construction of construction projects. Background technique [0002] The sand screening device at the construction site is a device for separating coarse and fine sand on the construction site. There are many types of the device, such as automatic sand screening devices, which are mostly used on large construction sites, and small manual sand screening devices, which are generally used For small construction sites, the small sand screening device is more convenient to move and use, and has a wider range of use, and will not be affected by factors such as electricity. [0003] After patent retrieval, the existing patent No. 201510488312.6 discloses a sand screening device, which includes a base 1 and a sand screening cylinder 2. A vibrating mechanism 3 is also provided at the bottom, and...

Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of adjustable inclined type sand screening device that is used for construction site construction, to solve the existing sand screening device proposed in the above-mentioned background technology, mostly is simple screen mesh structure, and structural design is simple, The rear side is supported by support rods to form a sand screening device. This type of sand screening device is less effective, and it is easy to mix the screened sand with coarse sand during sand screening, and the angle adjustment is more cumbersome; moreover, this type of sand screening device The sand sieve mesh of the device cannot vibrate, so the sand sieving efficiency and effect are poor; and the existing device cannot perform secondary screening, and the screened sand cannot be screened again by itself, so as to be used in other places, and further The problem of improving the utilization efficiency of sand in order to save costs
