Detailed Description

The invention will be further described with reference to the following drawings and examples:

example 1:

the utility model provides a grit screening counter weight structure, as shown in figure 1, includes that support body 1 and upper and lower screening storehouse 2 and the heavy storehouse of meter 3 of setting on

support body

1, 2 top outer walls in screening storehouse are equipped with the feed hopper 4 and communicate with the surge bin 21 of inside setting.

Buffering storehouse is as feeding decompression buffering position, can avoid concentrating on the shale shaker of grit, and is concrete, is equipped with auger 22 in the buffering storehouse 21 and is connected with the outside motor in screening storehouse 2, and buffering storehouse 21 bottom is equipped with a plurality of feed openings 23, specifically sets up to 3 in this embodiment.

Under the action of the auger 22, the sand and stone in the feed hopper are divided into three parts which enter the vibrating screen.

And the middle part of the screening bin 2 is provided with a plurality of vibrating screens 5 which are arranged in a staggered manner and are arranged at slopes, and the bottom of the screening bin 2 is provided with a screening bin feed opening 24.

Wherein, the slope of the vibrating screen 5 is 15 degrees to 25 degrees, in the embodiment, the preferred slope is 20 degrees, and the number of the vibrating screens is 2, so that the vibrating screen has a better screening effect.

Preferably, be equipped with the observation window on screening storehouse 2, and be equipped with discharge bin door 25 on the screening storehouse 2 of 5 lower limits of shale shaker positions department, the operator can survey the interior screening condition in storehouse in real time, and the condition of piling up on the shale shaker selects whether to need manual regulation.
