Gearbox for field operation machine

Abstract

Disclosed is a gearbox for a field operation machine. The gears of the gearbox comprises six forward gears, two reverse gears and an additional high-speed reverse gear which is used for achieving rapid reverse to improve operation efficiency; a planetary reducer is additionally arranged on the edge of the gears of the gearbox, so that the rotation speed can be reduced and the torque force can be improved to meet the mounting requirements of large tires, and further the crossing performance can be improved and the carrying capacity can be enhanced; brake discs are arranged at both ends of a lengthened fifth shaft respectively to achieve disk braking, so that the manufacturing cost can be reduced, the structure is simple and the maintenance is convenient.

Description

technical field [0001] The invention is a novel gearbox for farmland operation machinery. Background technique [0002] At present, most of the gearboxes used in domestic farmland operation machinery are gearboxes of small four-wheel tractors. For example, the gearboxes of Taishan 12 small four-wheel tractors are widely used. The gear settings are 6 forward gears and 1 reverse gear, and only 1 There is one reverse gear and the reverse gear speed is too low, which seriously affects the working efficiency; and its reduction ratio determines that when this type of gearbox is applied to agricultural machinery, it cannot be equipped with large tractor tires, and it is difficult to increase the bearing capacity and improve the passing performance. If equipped with large tractor tires The speed is too high and the torque is too small when used, which cannot meet the needs of farmland operations; the brake device of the Taishan 12 small four-wheel tractor gearbox is cumbersome, high...
