Hydraulic drive gearbox for harvesting machine

Abstract

The invention discloses a hydraulic drive gearbox for a harvesting machine. A gearbox input shaft is directly driven through a coupling sleeve by a hydraulic motor, and is meshed with a first-gear driven gear, a second-gear driven gear and a third-gear driven gear, which are arranged on a middle shaft, through a first-gear driving gear, a second-gear driving gear and a third-gear driving gear, which are arranged on the gearbox input shaft, and a gear hub and a gear sleeve, which are arranged on the middle shaft, so that three forward gears are formed. The hydraulic drive gearbox has the advantages that 1, the gearbox is directly driven by the hydraulic motor; 2, a gearbox assembly is reasonable in structure and compact in mounting size, and has three forward gear transmission ratios, the operation of the three gears is changed through a gear shifting control rod, and a neutral position for transition is formed between every two of the three gears, so that difficulty in the operation of the harvesting machine is effectively lowered, the space occupation of a cab is reduced, and a comfortable operating environment is created for a driver; 3, the gearbox is more rapidly and stably put into gear through a meshing sleeve; and 4, the gearbox is provided with a double-sided braking mechanism, and is suitable for harvesting machines under various working conditions, such as a cotton picker.

Description

technical field [0001] The invention relates to a hydraulically driven gearbox for harvesting machinery. Background technique [0002] At present, the hydraulically driven gearboxes used in domestic harvesting machines all use two shift levers and use sliding gears to shift gears, which have the following disadvantages: 1. The shift lever occupies a limited space in the cab and cannot bring the driver Comfortable operating environment. 2. To ensure that the pellets are returned to the warehouse within the limited harvest season, the design layout of the two shift levers and the sliding gear shift requires high operating skills and physical fitness of the driver, resulting in a serious waste of human resources. With the continuous progress of the country and the gradual reduction of the advantages of the demographic dividend, Harvest Machinery hydraulic drive gearbox is also facing an urgent need for replacement.
