Description

A kind of multistage Sand screen of construction

Technical field

The utility model relates to technical field of building construction more particularly to a kind of multistage Sand screens of construction.

Background technique

In construction, needing using a large amount of sand is arrived, each procedure needs the sand using different-grain diameter, but It is that the general sand particle size being just conveyed through is different, or even there is also many sandstones, this sand influences whether to construct Quality and construction progress, in addition the excessively multipair some engineerings of meticulous sand also have large effect, time-consuming to take if artificial sieve is husky Power.Sand screen used at present, it is either artificial or mechanical, it is all tentatively to screen out, not exclusively, process is more multiple for partial size separation It is miscellaneous, it takes a long time, use is more inconvenient, is also easy to cause to waste.

Utility model content

In order to solve the problems, such as to mention in above-mentioned background technique, it is husky that the utility model provides a kind of multistage sieve of construction Device.

To achieve the goals above, the utility model adopts the technical scheme that

A kind of construction multistage Sand screen, including body fuselage, the bottom surrounding of the body fuselage are fixed It is connected with supporting leg, the upper end side of the body fuselage is communicated with loading hopper, and the inner wall of the body fuselage is from top to bottom Being fixedly connected sequentially has several conically shapeds, and the upper end side of conically shaped is tiltedly installed with sieve plate, the bottom of the conically shaped Exit is provided with convex block, and the bottom wall of convex block is fixedly connected with strut, and the strut passes through the inner wall of body fuselage to extension It stretches end and is fixedly connected with motion bar, several springs, the machine are connected between the upper end of the strut and the outer wall of conically shaped The bottom of body case is communicated with out funnel.

Preferably, the aperture of the sieve plate gradually becomes smaller from top to bottom.

Preferably, the lower end side of the sieve plate is connected with slideway, and slideway extends outwardly across the inner wall of body fuselage.

Preferably, the lower end surface of the motion bar is fixedly connected with handle, and the outer wall of handle is equipped with anti-skid chequer.

Preferably, the upper surface of the convex block is convexity arc surface.

Compared with prior art, the utility model has the beneficial effects that sand to be sieved enters body through loading hopper In shell, and preferentially it is filtered along the sieve plate of first layer, and then slideway discharges the biggish sandstone of particle, and remaining is husky It is sub then entered in conically shaped by sieve plate, and after the sieve plate screening by multilayers such as the second layer, third layer, it is lesser to obtain partial size Sand so as to required, meanwhile, when sand blocking in conically shaped the case where, handle can be pulled downward on, so that motion bar It drives strut to move downward, and convex block is driven to move downward, and strut can be sprung back rapidly under the rebound effect of spring, To dredge to the sand of blocking, guarantee the husky normal work of sieve.The utility model structure is simple, easy to operate, to sand Multi-stage screening is carried out, the quality of sand is improved, and effectively prevent the generation of stopping state, is suitable for being widely popularized.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

In figure: body fuselage 1, loading hopper 2, conically shaped 3, sieve plate 4, slideway 5, strut 6, convex block 7, spring 8, motion bar 9, handle 10, out funnel 11, supporting leg 12.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1, a kind of construction multistage Sand screen, including body fuselage 1, the bottom surrounding of body fuselage 1 Be fixedly connected to supporting leg 12, the upper end side of body fuselage 1 is communicated with loading hopper 2, the inner wall of body fuselage 1 from upper and Under be fixedly connected sequentially and have several conically shapeds 3, and the upper end side of conically shaped 3 is tiltedly installed with sieve plate 4, the aperture of sieve plate 4 It gradually becomes smaller, sandstone can be screened step by step from top to bottom, the lower end side of sieve plate 4 is connected with slideway 5, and slideway 5 is worn The inner wall for crossing body fuselage 1 extends outwardly, and the biggish sandstone of particle is discharged along slideway 5, at the outlet at bottom of conically shaped 3 It is provided with convex block 7, the upper surface of convex block 7 is convexity arc surface, sand can be dredged, surface blocking outlet, and convex block 7 Bottom wall is fixedly connected with strut 6, and the inner wall that strut 6 passes through body fuselage 1 end that extends outwardly is fixedly connected with motion bar 9, activity The lower end surface of bar 9 is fixedly connected with handle 10, and the outer wall of handle 10 is equipped with anti-skid chequer, increases skin-friction force, helps to live Lever 9 pulls downward on, several springs 8, the bottom of body fuselage 1 are connected between the upper end of strut 6 and the outer wall of conically shaped 3 It is communicated with out funnel 11.

Working principle: in the utility model, sand to be sieved enters in body fuselage 1 through loading hopper 2, and preferential suitable The sieve plate 4 of first layer be filtered, and then slideway 5 discharges the biggish sandstone of particle, and remaining sand then passes through sieve plate 4 After sieve plate 4 into conically shaped 3, and by multilayers such as the second layer, third layer sieves, the lesser sand of partial size is obtained with toilet It needs, meanwhile, when sand block in conically shaped 3 the case where, handle 10 can be pulled downward on, so that the drive of motion bar 9 is propped up Bar 6 moves downward, and convex block 7 is driven to move downward, and strut 6 can be sprung back rapidly under the rebound effect of spring 8, from And the sand of blocking is dredged, guarantee the husky normal work of sieve.

More than, the only preferable specific embodiment of the utility model, but the protection scope of the utility model is not limited to In this, anyone skilled in the art within the technical scope disclosed by the utility model, according to the utility model Technical solution and its utility model design be subject to equivalent substitution or change, should all cover the protection scope of the utility model it It is interior.
