Movable rack for crop harvester as well as folding method and application of movable rack

Abstract

The invention discloses a movable rack for a crop harvester as well as a folding method and an application of the movable rack. The movable rack comprises a main rack, a power cylinder, a connecting plate and a moving rack, wherein the main rack comprises a short upper cross beam, a long lower cross beam and a support connecting plate between two ends of two cross beams; the rear end of the uppercross beam is hinged with the power cylinder and an oil cylinder baffle plate, the oil cylinder baffle plate is matched with the power cylinder and buckled on the power cylinder, two sides of the rearend of the lower cross beam are correspondingly hinged with two sides of the front end of the moving rack, the middle of a front panel of the moving rack is hinged with the rear part of the bottom end of a connecting plate, the front part of the bottom end of the connecting plate is hinged with the lower end of a telescopic rod of the power cylinder, the rear end of the upper part of the connecting plate is hinged with the lower end of the oil cylinder baffle plate, and the moving rack is buckled on the oil cylinder baffle plate in a foldable manner through the telescopic rod of the cylinder.The main rack and the moving rack are folded together conveniently, the width of the whole rack is reduced, transportation by a vehicle is facilitated, the rack is mounted on the crop harvester, andthe unfolding operation in the maximum width in the farmland can be met.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a crop harvester, in particular to a movable frame for a crop harvester and a folding method and application thereof. Background technique [0002] During the crop harvesting process, the frame of the crop harvester is often expanded to the maximum width when working in the field, and is used to install auxiliary functional parts, such as: placing a small cutter cutting disc for harvesting crops, auxiliary supporting driving wheels, and harvesting grain along the edge Wheels and other auxiliary accessories. According to the width of the harvesting header, it is often the largest width when working in the field. When it is required to drive in accordance with the traffic rules on the transition and on the road, the header frame needs to be folded and stored. If it cannot be folded, a large harvester It is very troublesome to use a special trailer for transportation when the fie...

According to the width of the harvesting header, it is often the largest width when working in the field. When it is required to drive in accordance with the traffic rules on the transition and on the road, the header frame needs to be folded and stored. If it cannot be folded, a large harvester It is very troublesome to use a special trailer for transportation when the field work is in transition.
