Abstract

The utility model discloses a simple sand and stone screen comprising a screen which is arranged inclined, a storage hopper, and legs of the storage hopper; wherein, the screen is connected to the inner of the storage hopper which is connected with the legs through the spring; the lower part of the storage hopper is connected with an material outlet and the side surface of the storage hopper which is abutting jointed to the lower edge of the screen is provided with a residue outlet; the storage hopper below the screen is provided with an eccentric shaft inside; on end of the eccentric shaft extending out from the storage hopper is connected with an eccentric wheel which is connected with an electromotor; a protection cover is fixed outside the eccentric shaft inside the storage hopper; the simple sand and stone screen has a simple structure and high level of mechanization, and can be used with a mechanical feed device, increase the sand screening speed and efficiency, reduce the work intensity of the manual work; at the same time, the screen can filter the aggregates and screes, further enhance the function; besides, the screen can be replaced at any time, in order to filter materials with different grains according to requirements.

Description

Simple and easy sandstone sieve

Technical field:

The utility model relates to the auxiliary equipment that an engineering construction is used, and relates in particular to a kind of simple and easy sandstone sieve that is used for the sub-sieve sandstone in the construction site.

Background technology:

At present, in most civilian or commercial and residential building and hydraulic engineering construction, still adopt the inclination sieve that installs of traditional type to screen to the sorting of used sand in the engineering, this sieve simple in structure, easy to make, low cost of manufacture, but this kind sieve is unsuitable for the mechanization operation, slow to the breakneck acceleration of sand, efficient is low, operator's labour intensity is big, and this kind sieve function singleness can't be screened stone.

Summary of the invention:

For overcome the traditional formula that installs sieve exist slow to the sand breakneck acceleration, efficient is low, the shortcoming of the big and function singleness of operator's labour intensity, the purpose of this utility model provide a kind of simple in structure, easily and other plant equipment cooperate and carry out sand, stone screening, improve the simple and easy sandstone sieve of husky, stone breakneck acceleration and efficient.

The technical solution of the utility model realizes in the following manner:

A kind of simple and easy sandstone sieve, it comprises screen cloth, feed bin, the feed bin supporting leg that is obliquely installed, wherein, screen cloth is connected in the feed bin, feed bin is connected on the supporting leg by spring, feed bin lower end connection discharging opening, the slag notch that the side has docks with the screen cloth lower edge, and the feed bin that is positioned at the screen cloth below is equipped with an eccentric shaft, eccentric shaft one end that appears feed bin is connected with an eccentric wheel that is connected with motor, and the eccentric shaft in the feed bin is fixed with a protective cover outward.

Eccentric wheel is a formed eccentric wheel behind a part of fan-like pattern hole of intercepting on the circular wheel body.

Eccentric axial portion in the feed bin is divided into oval eccentric shaft.

Also be fixed with stull on the supporting leg, the motor that is connected with eccentric wheel is installed in the stull.

Operation principle of the present utility model is:

Utilize driven by motor eccentric wheel and eccentric shaft to rotate and produce eccentric force, make feed bin produce vibration, driving screen cloth vibrates simultaneously, at this moment, foreign material such as clod that can't be by screen cloth, cobble, shell tumble on the screen cloth face that tilts by slag notch and separate, and sand by screen cloth or stone fall into the below and enter collecting device in order to using from discharging opening.

Good effect of the present utility model is:

Simple in structure, the mechanization degree height can be used with mechanical feed equipment, improves sand breakneck acceleration and efficient, reduces the labour intensity of manual work, and simultaneously, this sieve can also screen rubble, cobble, has further increased function; Screen cloth also can be changed at any time, so that as required the material of different-grain diameter is screened.

Description of drawings:

Fig. 1 is a structural principle schematic diagram of the present utility model.

Fig. 2 is the plan structure schematic diagram of Fig. 1.

Fig. 3 is the sectional structure schematic diagram of Fig. 2 along I-I.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

By Fig. 1, Fig. 2 as can be seen: the utility model comprises screen cloth 7, feed bin 1, the feed bin supporting leg 5 that is obliquely installed, wherein, screen cloth 7 is connected in the feed bin, feed bin is connected on the supporting leg by spring 3, feed bin lower end connection discharging opening 6, the slag notch that the side has docks with the screen cloth lower edge, the feed bin that is positioned at the screen cloth below is equipped with an eccentric shaft 8, and eccentric shaft one end that appears feed bin is connected with an eccentric wheel 2 that is connected with motor 4, and the eccentric shaft in the feed bin is fixed with a protective cover 9 outward.

Be it can also be seen that by Fig. 1: eccentric wheel is a formed eccentric wheel behind a part of fan-like pattern hole of intercepting on the circular wheel body.

Be it can also be seen that by Fig. 3: the eccentric axial portion in the feed bin is divided into oval eccentric shaft 8.

It can also be seen that by Fig. 1: also be fixed with stull on the supporting leg, the motor 4 that is connected with eccentric wheel is installed in the stull.
