Abstract

The utility model discloses a North China fritillary grade grading screen, which relates to a grading screen. The grading screen comprises a screen frame (1), a lower layer screen (2), a middle layer screen (3), an upper layer screen (4) and a driving shaft (5), wherein the lower layer screen (2) is arranged at the lower part of the screen frame (1); the middle layer screen (3) is arranged above the lower layer screen (2); the upper layer screen (4) is arranged above the middle layer screen (3); and the driving shaft (5) is connected with the lower layer screen (2) and the screen frame (1) through connecting rods. The grading screen can reduce the abrasion to the screen, and has high operating rate, high screening efficiency, low breakage rate and low cost.

Description

Flat shellfish grade classifying screen
Technical field:
The utility model relates to a kind of classifying screen, relates in particular to a kind of flat shellfish grade classifying screen.
Background technology:
The screen cloth of traditional flat shellfish grade classifying screen adopts wire netting, this screen cloth wearing and tearing are big, the soil peace shellfish mixture of rigid coring of flat shellfish and compass screen surface is tied the cake interlayer easily and is stopped up screen cloth easily, screening efficiency is low, and because the plansifter swing speed is fast, flat shellfish disrepair phenomenon is serious, and the flat shellfish of the part of screening directly influences growth in 1 year as seed.
The utility model content:
The purpose of this utility model provides a kind of flat shellfish grade classifying screen, it can reduce screen cloth wearing and tearing, operating rate height, screening efficiency height, breakage rate is low and cost is low.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of screen frame (unit) 1, lower screen 2, middle level sieve 3, upper sieve 4 and driving shaft 5, the bottom of screen frame (unit) 1 is provided with lower screen 2, the top of lower screen 2 is provided with middle level sieve 3, the top of middle level sieve 3 is provided with upper sieve 4, and driving shaft 5 links to each other with screen frame (unit) 1 with lower screen 2 by connecting rod.
The utility model is to drive lower screen by driving shaft, thereby drives middle level sieve 3 successively and upper sieve is made wobbling action, and flat shellfish is sieved.
The utility model has the advantages that it can reduce the wearing and tearing of screen cloth, operating rate height, screening efficiency height, breakage rate is low and cost is low.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
With reference to Fig. 1, this specific embodiment is by the following technical solutions: it is made up of screen frame (unit) 1, lower screen 2, middle level sieve 3, upper sieve 4 and driving shaft 5, the bottom of screen frame (unit) 1 is provided with lower screen 2, the top of lower screen 2 is provided with middle level sieve 3, the top of middle level sieve 3 is provided with upper sieve 4, and driving shaft 5 links to each other with screen frame (unit) 1 with lower screen 2 by connecting rod.
This specific embodiment is to drive lower screen 2 by driving shaft 5, thereby drives middle level sieve 3 successively and upper sieve 4 is made wobbling action, and flat shellfish is sieved.
The advantage of this specific embodiment is its wearing and tearing, operating rate height, screening efficiency height that can reduce screen cloth, breakage rate is low and cost is low.
