Description

Cross test sieve

Technical field

The utility model belongs to flour inspection machine field, the cross test sieve that particularly a kind of detection efficiency is high.

Background technology

In Flour production process, need constantly to detect the quality of flour, wherein flour mill milling efficiency is in many detections very important one, the milling efficiency of flour mill is embodied on break release and flour extraction rate, and flour mill milling efficiency has been come by test sieve, test sieve used at present once can only detect a kind of sample, each detection time is all more than 2.5 hours, there is very large defect in this test sieve that once can only detect a kind of sample, detection efficiency is low, need the manpower of at substantial, labor strength is large, corresponding testing cost is also just higher, this is very disadvantageous to enterprise.

The technical problems to be solved in the utility model is to provide the cross test sieve that a kind of detection efficiency is high, once can detect four kinds of samples simultaneously.

Utility model content

For solving the problems such as above-mentioned prior art detection efficiency is low, testing cost is high, now adopt following technical scheme:

The utility model provides a kind of cross test sieve, comprise screen box and several sieve lattice, described screen box is fixed on external transmission parametric controller, several sieve lattice overlaps described are placed in described screen box, described sieve lattice comprise sieve nest and cross screen frame, described sieve nest front is provided with semicircle salient point, described sieve nest reverse side is provided with semicircle concave point, several sieve lattice described are by semicircle salient point, semicircle concave point coordinates fixing in aggregates, all concave surface is provided with in the every 90 ° of directions of described sieve nest internal layer, four end shapes of described cross screen frame mate completely with described concave surface.

The beneficial effects of the utility model are: adopt cross screen frame, and once can detect four kinds of samples, detection efficiency significantly improves, and reduces testing cost, also reduces labour intensity simultaneously simultaneously, and structure is simple, and cost is low.

Detailed description of the invention

Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.

Refer to Fig. 1, a kind of cross test sieve, comprise screen box 1 and several sieve lattice 2, described screen box 1 is fixed on external transmission parametric controller, several sieve lattice 2 overlaps described are placed in described screen box 1, described sieve lattice 2(refers to Fig. 2) comprise sieve nest 21 and cross screen frame 22, described sieve nest 21 front is provided with semicircle salient point 23, Fig. 3 is referred at described sieve nest 21() reverse side is provided with semicircle concave point 24, several sieve lattice 2 described are by semicircle salient point 23, semicircle concave point 24 coordinates fixing in aggregates, concave surface 25 is all provided with in the every 90 ° of directions of described sieve nest 21 internal layer, four top 26 shapes of described cross screen frame (referring to Fig. 4) 22 are mated completely with described concave surface 25, by cross sieve diagrid frame design, once can carry out screen detection to four kinds of materials simultaneously, greatly improve the sifting efficiency of test sieve, improve detection efficiency, reduce the labour intensity of workman, also testing cost is reduced accordingly, the each parts of test sieve are all plastic materials simultaneously, low cost of manufacture, detachable maintaining is all very convenient.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
