Cab framework, cab and combine harvester

Abstract

The invention discloses a cab framework, a cab and a combine harvester, the cab framework comprises a cab main framework, a rear lower sealing plate, a rear upper sealing plate, a rear top sealing plate, a reinforcing rib I, a reinforcing rib II, an operation box mounting seat, a main seat mounting seat, an auxiliary seat mounting seat, a rear lower sealing plate and a rear upper sealing plate, the rear top sealing plate is welded on the rear side of the cab main framework; the first reinforcing rib is welded to the inner side of the rear upper sealing plate, the top of the first reinforcing rib is welded to the lower portion of the rear top ring beam, the second reinforcing rib is welded to the inner side of the rear lower sealing plate, and the longitudinal box mounting base, the main seat mounting base and the auxiliary seat mounting base are welded to the cab main framework bottom sealing plate. The whole header is of a closed structure, the structural rigidity and strength are high, and the view field requirements during rolling prevention and header replacement operation can be met.

Description

technical field [0001] The invention relates to a cab frame, a cab and a combine harvester, belonging to the technical field of agricultural machinery combine harvesters. Background technique [0002] The combine harvester involved in the present invention has a multi-purpose function of one machine, and can harvest crops such as corn kernels, millet, wheat, rice, soybeans, and rapeseed. When the combine harvester is operating in the field, the bumps are relatively strong, and the serious shaking of the cab will greatly increase the probability of the whole machine tipping over, which will seriously endanger the safety of the operator; in addition, the combine harvester needs to be replaced when operating on different grains. For the header, due to the difference in the structure of the header and the height of adjustment, the conventional cab frame cannot meet the lower vision requirements for observing different headers in front; the shape of the cab frame is too simple, w...
