Description

A portable sand and gravel screen for construction engineering

technical field

The invention relates to the technical field of sand and gravel screens, in particular to a portable sand and gravel screen for construction engineering.

Background technique

Sand is an indispensable basic raw material in the field of construction. There are various impurities in the sand, such as gravel, garbage, etc., and the sand in the sand is also divided into different grades and uses. different. Therefore, it is necessary to sieve the sand before using the sand. Since the sand is generally stacked outdoors, it will become wet and stick together after encountering rainy weather, resulting in the inability to fully screen out the required sand grains when sieving the sand. , increasing the cost of materials, and in some small construction sites, there is no need for too much sand, the cost of using a sand sifter is too high, and the sand sifter is inconvenient to transport.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a portable sand and gravel screen for construction engineering.

In order to achieve the above purpose, the technical solution of the present invention is as follows: a portable sand and gravel screen for construction engineering includes a sand feeding funnel, a metal mesh, a rotating mechanism, a box body, a motor and a bolt.

The bottom of the sand funnel is provided with an edge table, and a through hole is set on the edge table, the inner bottom of the sand funnel is provided with a circular cavity, the metal mesh is provided with a circular hole, and the rotating mechanism It includes a stage and a rotary table. There are many through holes on the stage. The lower part of the rotary table is provided with a driven gear. The driven gear is geared to the driving gear shaft of the motor. The upper surface of the rotary table is provided with several The first threaded hole, the bolt through hole is threadedly connected with the box screw hole provided on the box body, the bolt through hole is also threadedly connected with the second threaded hole set on the motor, the bolt through hole and The round hole is then screw-fastened with the first threaded hole, a hollow orifice is arranged inside the rotary table, a box door is arranged on one side of the box body, and four casters are installed on the bottom plate of the box body.

The working principle of the present invention is as follows: when in use, the forward and reverse rotation of the motor is controlled by an external control mechanism, and the driving gear shaft of the motor drives the driven gear to rotate reversely and forwardly, so that the rotary table can also rotate reversely and forwardly, and then The sand funnel is rotated in reverse and positive direction, and the sand and gravel input in the sand funnel are screened through the metal mesh, and the screened sand and gravel fall into the box through the hollow orifice.

The beneficial effects of the present invention are: the present invention can screen sand particles, and solves the problems of the existing sand screening machine being large in size, difficult to handle, and manual sand screening with high labor intensity, low work efficiency, high construction cost, and inconvenient movement of the sand and gravel screen. The utility model has the advantages of light weight and portability, simple structure and convenient use.

Detailed ways

As shown in the accompanying drawings, a portable sand and gravel screen for construction engineering of the present invention includes a sand feeding funnel 1 , a metal mesh 2 , a rotating mechanism 3 , a box body 4 , a motor 5 and a bolt 6 .

The bottom of the sand funnel 1 is provided with an edge table 12, and a through hole 121 is provided on the edge table 12. The inner bottom of the sand funnel 1 is provided with a circular cavity opening 11, and the metal mesh 2 is provided with The circular hole 21, the rotating mechanism 3 includes a stage 31 and a rotary table 32, a plurality of through holes 311 are set on the stage 31, a driven gear 321 is set on the lower part of the rotary table 32, the driven gear 321 and the motor The drive gear shaft 51 of 5 is geared for connection, the upper surface of the rotary table 32 is provided with a plurality of first threaded holes 322, the bolts 6 pass through the through holes 311 and the casing screw holes provided on the casing 4 are threadedly fastened. 6. The through hole 311 is also threadedly connected with the second threaded hole 52 provided on the motor 5. The bolt 6 penetrates through the through hole 121 and the round hole 21 and is then threadedly connected with the first threaded hole 322. A hollow orifice 323 is provided inside,

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

When in use, the forward and reverse rotation of the motor 5 is controlled by an external control mechanism, and the driving gear shaft 51 of the motor 5 drives the driven gear 321 to rotate reversely and forwardly, so that the rotary table 32 can also rotate reversely and forwardly, thereby making the sand The funnel 1 rotates reversely and forwardly, and continuously rotates reversely and forwardly. The sand and gravel put in the sand funnel 1 are screened through the metal mesh 2 , and the screened sand and gravel fall into the box 4 through the hollow orifice 323 .

As mentioned above, the embodiments are only to describe the preferred embodiments of the present invention, and do not limit the scope of the present invention. Such deformations and improvements shall fall within the protection scope determined by the claims of the present invention.
