Description

Portable sand and stone sieve for constructional engineering

Technical Field

The invention relates to the technical field of sand and stone sieves, in particular to a portable sand and stone sieve for constructional engineering.

Background

The sand is an essential basic raw material in the field of construction, various impurities such as broken stones, garbage and the like exist in the sand, sand grains in the sand are also classified into different grades, the purposes are different, and the required sand is different in grain size grade. Therefore, the sand needs to be screened before the sand is utilized, the sand is generally stacked outdoors, and can become wet and then be stuck together in rainy weather, so that the required sand particles cannot be sufficiently screened out in the sand screening process, the material cost is increased, too much sand is not needed in some small construction sites, the cost of the sand screening machine is too high, and the sand screening machine is inconvenient to transport.

Disclosure of Invention

The invention aims to provide a portable sandstone sieve for constructional engineering.

In order to achieve the purpose, the technical solution of the invention is as follows: a portable sand and stone screen for constructional engineering comprises a sand inlet funnel, a metal net, a rotating mechanism, a box body, a motor and a bolt.

Advance sand hopper's bottom set up along the platform, set up the via hole along the bench, sand hopper's inboard bottom set up the round chamber mouth, the metal net on set up the round hole, rotary mechanism include objective table and revolving stage, set up many through-holes on the objective table, the lower part of revolving stage has set up driven gear, driven gear carries out gear connection with the driving gear shaft of motor, the upper surface of revolving stage has set up many first screw holes, the bolt runs through the box screw that sets up on through-hole and the box and carries out screw thread fastening connection, the bolt runs through the through-hole and still carries out screw thread fastening connection with the second screw hole that sets up on the motor, the bolt runs through to pass through hole and round hole and carries out screw thread fastening connection with first screw hole again, the inside of revolving stage has set up the cavity drill way, one side of box has set up the chamber door, has installed four truckles.

The working principle of the invention is as follows: during the use, through the just, the reverse rotation of external control mechanism control motor, the driving gear shaft of motor drives driven gear and carries out the reversal, just rotates, can make the revolving stage also carry out the reversal, just rotates, and then makes the sand funnel carry out the reversal, just rotates, and constantly the reversal, just rotates, and the grit that drops into in the sand funnel passes through the metal mesh and screens, and the grit that screens falls into the box through the hollow drill way.

The invention has the beneficial effects that: the sand screening machine can screen sand, solves the problems of large size, difficult carrying, high labor intensity of manual sand screening, low working efficiency, high manufacturing cost and inconvenient movement of a sand screen in the prior sand screening machine, and has the advantages of light weight, portability, simple structure and convenient use.

Detailed Description

As shown in the attached drawing, the portable sandstone sieve for the constructional engineering comprises a sand inlet funnel 1, a metal net 2, a rotating mechanism 3, a box body 4, a motor 5 and a bolt 6.

The bottom of the sand inlet funnel 1 is provided with an edge table 12, the edge table 12 is provided with a through hole 121, the bottom of the inner side of the sand funnel 1 is provided with a round cavity opening 11, the metal net 2 is provided with a round hole 21, the rotating mechanism 3 comprises an object stage 31 and a rotating table 32, the object stage 31 is provided with a plurality of through holes 311, the lower part of the rotating table 32 is provided with a driven gear 321, the driven gear 321 is in gear connection with a driving gear shaft 51 of a motor 5, the upper surface of the rotating table 32 is provided with a plurality of first threaded holes 322, a bolt 6 penetrates through the through hole 311 and is in threaded fastening connection with a box body threaded hole arranged on a box body 4, the bolt 6 penetrates through the through hole 311 and is also in threaded fastening connection with a second threaded hole 52 arranged on the motor 5, the bolt 6 penetrates through the through hole 121 and the round hole 21 and is in threaded fastening connection with the first threaded hole 322, the rotating,

a box door 42 is provided at one side of the box body 4, and four casters 41 are mounted on a bottom plate 43 of the box body 4.

During the use, through the just, the reverse rotation of external control mechanism control motor 5, motor 5's driving gear axle 51 drives driven gear 321 and carries out the reversal, just rotation, can make revolving stage 32 also carry out reversal, just rotation, and then make sand hopper 1 carry out reversal, just rotation, constantly reversal, just rotation, the grit that drops into in the sand hopper 1 is filtered through metal mesh 2, and the grit that filters falls into in box 4 through hollow orifice 323.

The above-mentioned embodiments are merely descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
