Embodiment 1

[0030] see Figure 1-4 , a sand screening device for construction, including a base 1, a mounting frame 2 and a feed hopper 4, the mounting frame 2 is welded on the base 1, and the feeding hopper 4 is fixedly installed above the mounting frame 2, and also includes a Screening components for sand;

[0031] The specific type of the screening assembly is not limited. In this embodiment, preferably, the screening assembly includes a screening frame 3, a sieve plate 12, a first discharge channel 13, a second discharge channel 14, and a movable plate 19. Screening The frame 3 is installed on the movable plate 19, the sieve plate 12 is obliquely installed in the screening frame 3 and the side wall of the screening frame 3 on the lower side is connected with the first discharge channel 13, and the second discharge channel 14 is connected with the screening frame 3 Bottom side wall, the bottom of the movable plate 19 is connected with a driving assembly that drives the movable plate 1...

Embodiment 2

[0044] see Figure 5 , in order to improve the screening efficiency of sand, the present embodiment is further improved on the basis of embodiment 1, and the improvement is that: the crushing roller group 30 is installed in rotation in the feed hopper 4, and the crushing roller group 30 is connected with a crushing motor 31. The crushing motor 31 is fixedly installed outside the feed hopper 4, and by crushing the sand in the feed hopper 4, it prevents the agglomerated sand from entering the screening frame 4, resulting in the sieve plate 12 and the first discharge channel 13 Blockage, improve screening efficiency and practicability.

[0045] To sum up, by setting the screening assembly and the driving assembly, the motor 25 drives the turntable 27 to rotate, and then drives the push rod 21 to reciprocate through the connecting rod 26, so that the slider 20 and the movable plate 19 vibrate slightly along the chute 23, The sand on the sieve plate 12 is accelerated to be sieved,...

Abstract

The invention discloses a sand screening device for constructional engineering. The sand screening device for constructional engineering comprises a pedestal, a mounting frame and a feeding hopper; the mounting frame is welded on the pedestal; the feeding hopper is fixedly mounted above the mounting frame; the sand screening device for constructional engineering further comprises a screening assembly for screening sand and an intermittent discharging assembly; the screening assembly comprises a screening frame, a screening plate, a first discharging channel, a second discharging channel and amovable plate; the bottom of the movable plate is connected to a driving assembly for driving the movable plate to waggle left and right; the driving assembly comprises a sliding block, a push rod, asliding groove, a guide rod, a motor and a connecting rod; the intermittent discharging assembly comprises an auxiliary plate, a blocking plate, a pull rope, a through hole, a first limiting rolling wheel, a second limiting rolling wheel, a buffering spring and a telescopic rod; and through the screening assembly, the intermittent discharging assembly and the driving assembly, a motor drives a turnplate to rotate, so that a push rod is driven by a connecting rod to move back and forth, the sliding block and the movable plate joggles along a sliding groove to a small extent, screening of sand on a screening plate is accelerated, and the screening efficiency is improved.

Description

technical field [0001] The invention relates to the construction field, in particular to a sand screening device for construction engineering. Background technique [0002] Broadly speaking, architecture is the study of buildings and their environments. Architecture is a discipline that straddles engineering technology and humanities. The architectural art and architectural technology involved in architecture, as well as the aesthetic and practical aspects of architectural art as a practical art, although they are clearly different, they are closely related, and their weight varies with the specific situation and the structure of the building. very different. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction works is called "construction site" or "construction site", also called construction site. [0003] Sand screening machine, also known ...
