Abstract
An earthworm-imitating peristaltic corn cleaning mechanism belongs to agricultural machinery; the purpose is cleaned maize seed grain through sifter formula motion of creeping, because the pendulum rod carries out the fore-and-aft swing around the connecting rod, drive the motion of sifter dead lever between from top to bottom and the front and back, consequently, sifter 1 also can carry out the motion between from top to bottom and the front and back at the sifter dead lever, and there is slide bar connection's sieve piece 2, 3, because the slide bar can only move in the slide of frame assembly, consequently can be continuous between each sieve piece change between crooked and exhibition flat, make the sieve piece can carry out the motion of similar earthworm formula of creeping, the maize of throwing out of the thing is thrown in the disturbance, make its dispersion, then the exhibition is flat, make the material migrate backward, prevent to block up. When the two sieve sheets are in a bent state, the airflow flows through the protrusions, the flowing speed of the airflow is increased, the adhesion between the sieve sheets and corn threshed objects is reduced, the feeding amount is improved, and the corn threshing and cleaning device has the characteristics of novel and reasonable structure, high cleaning operation efficiency, good quality and reliability in use.
Description
Technical Field
The invention belongs to agricultural machinery, and mainly relates to an earthworm-imitating peristaltic corn cleaning mechanism.
Background
At present, the traditional corn vibration sieve is not enough in the aspect of design, the freedom degree of motion is less, the direction of motion is single, only plane reciprocating motion can be carried out, the sieve efficiency is low, the sieve body is a whole sieve, the kernel can pass through the sieve in the sifting surface one dimension, the kernel is difficult to disperse on the sifting surface, the particles are easy to appear the phenomenon of piling on the sifting surface, the sieving efficiency of the vibration sieve is reduced, and the sieving effect is influenced.
Disclosure of Invention
Aiming at the problems, the invention aims to design a screen surface movement mechanism based on the characteristic that the earth can be disturbed by the creeping of earthworms so as to realize the change movement of a screen sheet, realize the telescopic movement of the screen sheet in the horizontal direction and the convex and flattening movement in the vertical direction, disturb the material on a screen by the creeping change of the screen surface, disperse the material and achieve the aim of improving the corn cleaning operation efficiency.
The purpose of the invention is realized as follows: connecting rods (2) are hinged at the front end and the rear end of a frame assembly (1), the two sides of each connecting rod (2) are limited by split pins (3), swing rods (4) are hinged at the two sides of each connecting rod (2), the swing rods (4) can swing around the connecting rods (2), the swing rods (4) at the front end and the rear end are hinged with a sieve piece fixing rod (11) through short pin shafts (10), sieve pieces (1), (5) are fixed with the sieve piece fixing rod (11), the sieve pieces (2), (6) are hinged with the sieve pieces (1), (5) through pin shafts (8), the sieve pieces (2), (6) are hinged with the sieve pieces (3), (7) through slide rods (9), so that the sieve pieces (2), (7) and the sieve pieces (3), (7) can rotate around the centers of the slide rods (9), the slide rods (9) are arranged in a slide way of the frame assembly (1) and can freely slide in the slide way, the sieve pieces (3), (7) are hinged with the sieve pieces (1), (5) through the pin shafts (8), and the two sides of the pin shafts (8) are limited by the split pins (3), the sieve sheets 1(5), 2(6), 3(7) are installed backwards in the same way; the screen sheet assembly continuously realizes protrusion and flattening through the swinging of the swing rod (4), and the screen surface moves to form a movement form similar to the creeping of earthworms.
According to the characteristics that the body surface is periodically changed in the wave form and the soil is disturbed according to the alternate contraction and relaxation process of the circular muscles and the longitudinal muscles of the earthworms in the soil, a vibrating screen is designed according to the movement form of the wriggling of the earthworms, the corn threshed objects are disturbed to disperse the corn threshed objects and then flatten the corn threshed objects, so that the materials are transported backwards to prevent blockage. When the corn cleaning operation is carried out, when the two sieve sheets are in a bent state and the airflow flows through the protrusions, the flowing speed of the airflow is increased, so that the adhesion between the sieve sheets and corn threshed objects can be reduced, the feeding amount is increased, and the corn cleaning machine has the characteristics of novel and reasonable structure, high cleaning operation efficiency, good quality and reliable use.

1. the device comprises a frame assembly, 2, connecting rods, 3, cotter pins, 4, swing rods, 5, sieve sheets 1 and 6, sieve sheets 2 and 7, sieve sheets 3 and 8, pin shafts, 9, slide rods, 10, short pin shafts, 11 and sieve sheet fixing rods.
Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Connecting rods (2) are hinged at the front end and the rear end of a frame assembly (1), the two sides of each connecting rod (2) are limited by split pins (3), swing rods (4) are hinged at the two sides of each connecting rod (2), the swing rods (4) can swing around the connecting rods (2), the swing rods (4) at the front end and the rear end are hinged with a sieve piece fixing rod (11) through short pin shafts (10), sieve pieces (1), (5) are fixed with the sieve piece fixing rod (11), the sieve pieces (2), (6) are hinged with the sieve pieces (1), (5) through pin shafts (8), the sieve pieces (2), (6) are hinged with the sieve pieces (3), (7) through slide rods (9), so that the sieve pieces (2), (7) and the sieve pieces (3), (7) can rotate around the centers of the slide rods (9), the slide rods (9) are arranged in a slide way of the frame assembly (1) and can freely slide in the slide way, the sieve pieces (3), (7) are hinged with the sieve pieces (1), (5) through the pin shafts (8), and the two sides of the pin shafts (8) are limited by the split pins (3), the sieve sheets 1(5), 2(6), 3(7) are installed backwards in the same way; the screen sheet assembly continuously realizes protrusion and flattening through the swinging of the swing rod (4), and the screen surface moves to form a movement form similar to the creeping of earthworms.
During operation, under the driving of a motor (not shown in the figure), the swing rod (4) swings back and forth around the connecting rod (2) to drive the screen piece fixing rod (10) to move up and down and back and forth, so the screen piece (1) (5) can also move up and down and back and forth on the screen piece fixing rod (10), and the screen pieces (2) (6), 3(7) connected with the slide rod (9) can only move in the slide way of the frame assembly (1), so the screen pieces can be continuously switched between bending and flattening, the screen pieces can move like an earthworm creeping type, the corn threw-off objects are disturbed and thrown up to disperse, and then the corn threw-off objects are flattened to move the materials backwards to prevent blockage. When the screen surface is in a bent state, under the cooperation of air flow of a fan (not shown in the figure), the air flow can increase the flowing speed of the air flow when flowing through the protrusions, so that the corns can continuously jump and turn over in the moving process, and the cleaning operation with high quality and high efficiency is completed.
