Abstract

The invention discloses a hydraulic-driving ear picking device. A hydraulic system is adopted for the device. By arranging an electromotor, an output shaft of the electromotor is connected with an input shaft of a transfer case through a shaft coupling. An output shaft of the transfer case is connected with an input shaft of a hydraulic pump I and an input shaft of a hydraulic pump II. An oil inlet of the hydraulic pump I and an oil inlet of the hydraulic pump II are connected with an oil tank oil pipe, an oil outlet of the hydraulic pump I is connected into a corn ear picking system through an oil pipe, and an oil outlet of the hydraulic pump II is connected into an ear picking roller gap adjustment system through an oil pipe. The hydraulic-driving ear picking device has the advantages ofbeing simple in transmission structure, low in weight, convenient to control, easy to operate, good in safety and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a hydraulically driven ear picking device. Background technique [0002] Different varieties of corn have different thicknesses of stalks. The ear picking device is one of the main working parts of the corn harvester, and the ear picking roller clearance and the ear picking roller speed are the main factors affecting the corn ear damage during the corn harvesting process. With harvesting quality. Most of the existing ear picking roller gap adjustments are manually adjusted, while the ear picking devices generally use traditional mechanical transmission, which makes the machine transmission complicated, low in efficiency, inflexible in control, prone to blockage and inconvenient to maintain, and the transmission ratio is fixed, making the ear picking The roller speed is fixed and the adaptability is low. Contents of the invention [0003] The object of the prese...
