Embodiment 1

[0030] The present invention provides a technical solution: a device for sand and gravel sieving and cleaning in construction engineering, including a bottom plate 1, which is characterized in that: the top of the bottom plate 1 is symmetrically arranged with rollers 2 left and right, and the left side of the top of the bottom plate 1 is provided with a cleaning The sub-sieve box 3, the upper part of the inner cavity of the cleaning sub-sieve box 3 is provided with a first screen 4, the lower part of the inner cavity of the cleaning sub-sieve box 3 is provided with a second screen 5, and the left side wall of the cleaning sub-sieve box 3 is spaced There are three sets of discharge ports 6. The three groups of discharge ports 6 are respectively located on the top left side of the first screen 4, the second screen 5 and the inner bottom wall of the cleaning sub-sieve box 3. The discharge ports 6 are installed There is an automatic opening and closing door 7, and a water level det...

Embodiment 2

[0035]Piston pumping mechanism 14 comprises piston cylinder 141, and piston cylinder 141 left end openings are provided with piston plate 142 in piston cylinder 141, and piston plate 142 left end is hinged with connecting rod 143, and the right side of piston cylinder 141 bottom wall is provided with water inlet pipe 144, and piston A water outlet pipe 145 is provided on the right side of the top wall of the cylinder 141 , and a check valve 146 is provided on the water inlet pipe 144 and the water outlet pipe 145 .

[0036] In the above structure, the connecting rod 143 reciprocates under the traction of the crank shaft 21 to drive the piston plate 142 to move left and right, and the water in the cleaning and screening box 3 is continuously pumped into the water storage tank 13 by changing the air pressure, so that The liquid level in the cleaning sub-sieve box 3 drops.

Embodiment 3

[0038] The multifunctional rod 20 includes a rod body 201, and a strip plate 202 is distributed on the lower part of the rod body 201, and the strip plate 202 is divided into upper, middle and lower layers.

[0039] In the above structure, the two strip plates 202 on the upper side can promote the sieving of sand and gravel during sieving and cleaning, and also make the sand and gravel cleaning more thorough.

Abstract

The invention discloses a sand and gravel sieving and cleaning device for construction engineering in the technical field of construction engineering equipment. The sand and gravel sieving and cleaning device comprises a bottom plate; rollers are symmetrically arranged left and right at the top end of the bottom plate; a cleaning and sieving box is arranged on the left side of the top end of the bottom plate; a first screen is arranged at the upper part of an inner cavity of the cleaning and sieving box; a second screen is arranged at the lower part of the inner cavity of the cleaning and sieving box; and three groups of water outlets are formed in the left side wall of the cleaning and sieving box at intervals. The cleaning and sieving process of sand and gravel is completed in water, sothat noise generated during the sieving and cleaning process is greatly reduced, and the maintenance of the construction site environment is facilitated; through the arrangement of a piston pumping mechanism, a purification box and other structures, the water purification cycle in the sieving and cleaning process of sand and gravel can be realized, and as the liquid level decreases, sieved sand and gravel particles can be discharged in time; and the structure is ingenious and creative.

Description

technical field [0001] The invention relates to the technical field of construction engineering equipment, in particular to a sand screening and cleaning device for construction engineering. Background technique [0002] With the gradual development of my country's economic construction, construction projects are being carried out all over the country, and various residential buildings, office buildings, road projects and other projects are under construction. With the development of science and technology today, super high-rise buildings appear widely in urban construction. Super high-rise buildings refer to buildings with more than 40 floors and a height of more than 100 meters. Super high-rise buildings embody the continuous progress of human science and technology civilization, and a large number of super high-rise buildings have also greatly changed the appearance of cities. [0003] With the emergence of more and more large-scale buildings, it is inevitable to use san...
