Pull-type fresh maize bionic ear-picking harvesting bench

Abstract

The invention discloses a pull-type fresh maize bionic ear-picking harvesting bench. The harvesting bench comprises a rack, a pair of parallel snapping rolls which have a gap, and a pair of annular clamping chains. The rack is divided into a left side part and a right side part, and a gap is reserved between the two parts, and the two parts are symmetrically distributed relative to a feeding center line. The snapping rolls are arranged above a horizontal segment of the rack in an inclined manner relative to the horizontal segment, and heights of the snapping rolls being adjustable. Each of theannular clamping chains is arranged on the rack above the snapping rolls along the direction vertical to the feeding center line in transmission and adjustable manner, and the annular clamping chainsand ground form a certain angle. Pressing forces of the clamping chains of the ear-picking harvesting bench are distributed in a uniform manner, and acting forces of clamping positions of maize plants are maximum all along, to effectively protect maize plants and reduce damages.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a bionic traction-based harvesting platform for harvesting ears of corn. Background technique [0002] Corn is the second largest grain crop in my country, and its output is increasing year by year. In the past, corn, as one of the sources of feed and important chemical raw materials, has always been in an important position in my country's grain. In recent years, with the improvement of people's living standards and the change of social consumption structure, fresh corn has been favored by more and more people for its unique taste and rich nutrition. [0003] The traditional corn harvesting machine picks the ear mainly by using the stem puller or the ear picker to grab the corn stalk for positive stretching, and then break the ear stalk connecting the root of the corn ear to the stalk, so that the ear and the stalk can be separated. Separation to achieve the process of pi...

Problems solved by technology

However, it is impossible to effectively adjust the position of the corn plant to facilitate ear picking. Chinese Patent Publication No. (CN 102640619 A) provides a clamping chain that utilizes different speeds to adjust the position of the ear of corn, but it can only be adjusted along the feeding center line. direction translation, when the chain moves, the friction force between the chain and the clamping plate acts on the clamping plate, which will cause the clamping plate to be stuck, and the pressing force on the clamping chain in the direction perpendicular to the feeding center line is the same everywhere, which is easy to cause Damage to corn stalks, not conducive to recycling
