Beating sieve cleaning mechanism of peanut rotary drum grader

Abstract

The invention relates to a modified structure of a peanut grader in an agriculture machine, and discloses a beating sieve cleaning mechanism of a peanut rotary drum grader. The beating sieve cleaning mechanism of the peanut rotary drum grader comprises grading rotary drums (1) of the peanut rotary drum grader; beating shafts (2b) parallel to axes of the grading rotary drums (1) are arranged on outer sides of the grading rotary drums (1), and a plurality of beating rollers (2) are configured on each beating shaft (2b) along the length direction of the axis of the corresponding grading rotary drum (1); a plurality of rectangular beating plates (2a) are fixed to the outer peripheral wall of each beating shaft (2b) in a cantilever manner, and are flexible elastic plates, one end of each beating plate (2a) is fixed to the outer wall of the corresponding beating shaft (2b), and an included angle is formed by each beating plate (2a) and a radial line fixed onto the outer wall of the corresponding beating shaft (2b), and ranges from positive or minus 90 degrees to positive or minus 150 degrees; 1 / 2-1 / 3 parts of the beating plates (2a) of the beating rollers (2) in length directions of the beating plates (2a) are in contact with surfaces of the grading rotary drums (1) during rotation; and rotational directions of the beating rollers are opposite to those of the grading rotary drums, and linear velocities of contact positions among the beating plates on the beating rollers and the surfaces of the grading rotary drums are different. The beating sieve cleaning mechanism solves the problem of blockage of sieves of existing grading rotary drums in a peanut pod grading procedure.

Description

technical field [0001] The invention relates to an improved structure of a peanut classifier in agricultural machinery, in particular to an improved structure of a peanut roller classifier. Background technique [0002] There is no special grading equipment for peanut pods in China. Peanut pods are graded by existing general-purpose equipment. However, due to the rough appearance of peanut pods and the special physical properties of pods that are crooked and pitted, peanut pods are classified using traditional roller grading equipment. When grading, it is often difficult to pass through the grading screen, causing serious blockage of the screen, and it is often difficult to clear the blockage of the screen surface with a single slap, which eventually makes the grading difficult to proceed smoothly. [0003] A related patent was found in the search, the patent number is 93243240.9, a vertical circular rotary vibration peanut classifier, which is composed of a multi-layer rota...
