Simple screening equipment of legume crops

Abstract

The invention discloses simple screening equipment of legume crops. The simple screening equipment structurally comprises a primary screen, a secondary screen, a tertiary screen, a quaternary screen, slide rails, an outer tubular wall, a transmission spindle, a motor, a crankshaft and rollers. The motor is connected with the crankshaft. The crankshaft is connected with the transmission spindle through a connecting shaft. When the motor drives the crankshaft to rotate, the crankshaft drives the transmission spindle to move up and down. The primary screen, the secondary screen, the tertiary screen and the quaternary screen are mounted on the transmission spindle sequentially from top to bottom. The hollow holes of each screen sequentially decease in size. The rollers are mounted on two sides of the screens. The slide rails are disposed on the left and right of the inner wall of the outer tubular wall. The rollers are mounted on the slide rails. The multiple screens are designed, the hollow holes of each screen sequentially decrease in size, the legume crops are graded during screening, and the simple screening equipment is simple in structure, low in cost and accordingly widely applicable.

Description

technical field [0001] The invention relates to a machine for screening agricultural crop products, in particular to a simple screening equipment for bean crops. Background technique [0002] The bean crop screening is to separate the sand, stone, dust and other sundries in the bean crops through the filter screen. The traditional screening method is to manually shake the filter sieve for screening, which has low efficiency and high labor intensity. The structure of the existing vibrating screening machine is relatively complicated, and each mesh screen needs to be equipped with a vibrating mechanism, and the manufacturing cost is relatively high. Therefore, there is a need for a bean crop screening machine, which not only has high screening efficiency and high screening accuracy, but also has the characteristics of simple structure and low manufacturing cost. Contents of the invention [0003] Aiming at the shortcomings of the existing bean crop drying devices, the pre...
