Coupled bionic self-leveling high-humidity corn grain harvesting vibration cleaning device

Abstract

A coupled bionic self-leveling vibration cleaning device for harvesting high-humidity corn grains, including a frame, a right hood, a left hood, an upper cleaning mechanism, a transmission mechanism, a lower cleaning mechanism, a front grain conveying auger, The rear grain conveying auger, the leveling vibration damping seat, the air inlet, the rear grain opening, the front grain opening and the bottom cover, the upper cleaning screen and the lower cleaning screen realize the horizontal direction through the horizontal vibration damping spring and the vertical vibration damping spring and vertical micro-vibration, the bionic ridge cover of the upper cleaning sieve breaks the adhesion between the high-humidity corn and the substrate of the upper cleaning sieve, reducing the cleaning loss rate of high-humidity corn; the bionic spherical cover of the lower cleaning sieve blocks The high-humidity corn cob shaft passes through the lower cleaning sieve to improve the cleaning rate; the leveling and damping seat uses the leveling ball head and the leveling ball seat to realize the constant maintenance of the upper cleaning mechanism, the lower cleaning mechanism and the rack. Horizontal, to prevent the uneven distribution of high-humidity corn on the surface of the upper and lower cleaning sieves caused by inclination, and to avoid the reduction of cleaning efficiency caused by the uneven terrain of the field.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a coupling bionic self-leveling vibration cleaning device for harvesting high-humidity corn grains. Background technique [0002] Corn is the main food crop in my country, and corn harvesting machinery is the main model of agricultural machinery. The corn harvesting process can be divided into ear picking type and grain direct harvesting type. Harvesting machinery for corn grain direct harvesting includes working devices such as ear picking, peeling, threshing, and cleaning. Among them, the cleaning device has long-term problems such as mandrel blockage of the screen hole, bract leaf adhesion to the screen surface, and air field interference with the cleaning movement, resulting in The corn kernels do not penetrate the cleaning unit sufficiently, and large quantities of kernels are expelled from the cleaning unit, causing severe cleaning losses. In addition, the moisture content of cor...

Problems solved by technology

[0003] At present, the cleaning device of corn grain direct harvesting machines at home and abroad mainly realizes the horizontal reciprocating motion of the screen surface through the four-bar mechanism. The mechanical properties are fully integrated, resulting in the existing cleaning device's sieve hole clogging and serious adhesion on the sieve surface, low seed penetration rate, uneven distribution of the cleaning mixture on the sieve surface, high cleaning loss rate, and large operating power consumption
