Reverse flexible corn stalk picking device

Abstract

The invention discloses a reverse flexible corn stalk picking device which comprises a rack, a device cover, an upper picking mechanism and a lower picking mechanism. In the working process, a picking shovel is put deeply to the lower portion of a lodging stalk to shovel the lodging stalk out, the upper picking mechanism rotates counterclockwise to poke the shoveled stalk to the position behind the device, and the stalk is conveyed to subsequent processes under the drive of a conveying rod. In the moving process of a horizontal picking mechanism, telescopic fingers located on picking plates in the horizontal direction fall perpendicularly under the action of gravity, so that picking rods on the left horizontal picking plates form the optimal picking combination, and picking rods on the right horizontal picking plates form the optimal picking disengaging combination. The tangential force exerted on the stalk in the horizontal direction is opposite to the work advancing direction, and therefore the relative picking speed of the stalk is improved. A longitudinal beam, a front arm, a rocker arm and a rear arm form a quadrangle mechanism, a flexible obstacle crossing function is achieved under the assistance of a spring, impact damage to the picking shovel by obstacles is effectively relieved, and the obstacle crossing capability and the work passing capability of the whole device are improved.

Description

technical field [0001] The invention relates to a pick-up device, in particular to a reverse flexible corn stalk pick-up device, which belongs to the field of agricultural machinery. Background technique [0002] As the main agricultural solid waste, corn stalks are rich in biomass energy. Strengthening the recycling of corn stalks can not only alleviate the energy crisis, but also reduce the environmental pollution caused by straw burning. Corn stalk picking device is the main agricultural equipment in the process of straw recycling. The current picking device is mainly divided into self-propelled and traction type in terms of operation mode. The typical foreign straw pickers include John Deere and Case. Straw pickers are typical straw picking and recycling products produced by Inner Mongolia Huade Machinery Co., Ltd. At present, the following problems still exist in the corn straw picking devices at home and abroad: (1) The integrated design and production of the picking ...

AI Technical Summary

Problems solved by technology

At present, the following problems still exist in the corn straw picking devices at home and abroad: (1) The integrated design and production of the picking device and the bundling device increase the product cost of corn straw recycling and restrict the diversified product demand of farmers, especially for corn straw Pickup device requirements

(2) The existing corn stalk picking device completely relies on the spring finger, and picks up the stalks in a clockwise manner, so that the stalks only receive an independent picking force in the same direction as the operation, resulting in straw splashes; Lost a lot of work

(3) The existing corn stalk pick-up device travels rigidly, and directly overturns when encountering obstacles during operation, resulting in missed pick-up of corn stalks; at the same time, the position close to the ground lacks synchronous pick-up and cleaning devices, which reduces the overall efficiency of straw pick-up efficiency
