Up-down inertia force type corn header ear picking device

Abstract

The invention discloses an up-down inertia force type corn header ear picking device which comprises two pairs of four inertia ear picking rollers, a guide cone, a diameter increasing pad, a long diameter increasing pad, a protective cylinder, an ear picking plate, a reel and the like. The two pairs of four snapping rollers are mounted in the protective cylinder in parallel up and down, the front parts of the snapping rollers are connected with the guide cone, and central shafts at the rear parts of the snapping rollers are mounted on the bearings; spiral ribs are welded on the snapping rollers and the guide cones, and the spiral directions are opposite, so that the backward conveying of corn straws is ensured; the diameter increasing pads are located between the spiral protruding edges and make contact with the snapping rollers, and the diameter increasing pads are installed on the two pairs of snapping rollers in the left-right same mode and staggered in the up-down mode so that it can be guaranteed that only the diameter increasing pads on one pair of snapping rollers make contact with corn straw in the snapping process. The ear picking plate is connected with the rear end of the upper protective cylinder; and the long diameter-increasing pad is positioned at the rear ends of the next pair of snapping rollers. According to the principle that the vertical inertia force, caused by exciting force, of corn ears is larger than the connecting force of the corn stems, corn non-contact ear picking is achieved. The innovative mechanism can effectively reduce the bite damage and breakage rate of ears, improve the ear picking efficiency and realize high-efficiency and low-loss corn harvesting mechanization.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an up-and-down inertial force-type ear picking device for corn headers. Background technique [0002] Corn is widely planted as the main food and feed crop in my country, as well as the important economic income of farmers. However, the degree of mechanization of corn harvesting is low, and the problems of ear gnawing and grain damage seriously restrict the quality of corn harvesting. Therefore, modern agricultural harvesting machinery has low efficiency and low efficiency. There is an urgent need for loss harvesting techniques. [0003] Corn ear picking is to separate the ear from the stalk under the action of the ear picking roller. The basic principle is the difference in diameter between the ear and the stalk, and the difference in the connection force between the ear point and the other parts of the stalk to achieve the ear picking operation. At present, there...
