Corn cob picking device with quick-return characteristic and manual work simulation function

Abstract

The invention relates to a corn cob picking device with the quick-return characteristic and the manual work simulation function, and belongs to the field of agricultural machines. The corn cob picking device comprises a rack (1), a chain transmission mechanism (8) and bias crank-slider cob picking mechanisms (6). The corn cob picking device is characterized in that external power is transmitted to the chain transmission mechanism (8) through an input chain wheel (14), cob picking hands (17) can do reciprocating rectilinear movement along cob picking slideways (3), and cranks (7), links (5) and sliders (4) form the bias crank-slider cob picking mechanisms (6). The corn cob picking device has the quick-return characteristic, namely, the two cob picking hands pick cobs downwards in the working process of the cob picking mechanisms and then return upwards quickly within a short time; the cob picking hands generate large impact force when picking cobs downwards and can rotate downwards when returning to reduce influences on motion of corn plants, and return springs (16) can guarantee that the cob picking hands (17) enter a next motion period in a working state when the highest limit is reached. The cob picking mechanisms create conditions for easy and low-energy-consumption corn harvesting.

Description

technical field [0001] The invention relates to a corn ear breaking principle and a corn ear breaking device suitable for being installed on a corn harvester, in particular to a corn ear breaking device with quick return characteristics imitating manual operation, which belongs to the technical field of agricultural machinery. Background technique [0002] The ear picking device is the main working part of the corn harvester. At present, the main ear picking device is mainly a roller-type ear picking device. The principle of this type of device is different from that of manual ear picking. It is very unreasonable to stretch the corn stalk and forcibly squeeze the corn ear to separate the stalk and ear. The disadvantages of this type of roller-type ear picking device are that the structure is complex, heavy, power consumption is large, and the work efficiency is low, so the cost of corn harvesting remains high; Compared with the ear plate type, it has the advantages of bette...

AI Technical Summary

Problems solved by technology

[0004] The invention overcomes the shortcomings of the traditional roller-type ear picking device, such as complex structure, high energy consumption, and poor practicability, and provides a corn ear breaking device with rapid return characteristics that imitates manual operation, can reciprocate and quickly break ears, and has a good bionic effect , low energy consumption, high efficiency, etc.
