Electrically-controlled embedded liftable mowing platform

Abstract

According to the electrically-controlled embedded liftable mowing platform, a groove for embedding a mowing platform body is formed in the middle of a frame, so that the weight of the mowing platform is effectively reduced; a plurality of groups of mowing motors are arranged on the header framework of the header body, the maintainability is good, a cutter rotating mechanism is arranged below each group of mowing motors, two lifting lead screws are symmetrically arranged in the middle of the header framework, one end of each lifting lead screw is fixed on the header framework, and the other end of each lifting lead screw is embedded into the frame. A driving chain wheel nut of the header lifting mechanism is sleeved on one lifting lead screw, a driven chain wheel nut is sleeved on the other lifting lead screw, the upper end of a header lifting motor is installed on the frame, the lower end of the header lifting motor is connected with the driving chain wheel nut sleeved on the lifting lead screw, and the driven chain wheel nut is connected with the driving chain wheel nut. Power output from the header lifting motor serves as a mowing platform transmission mechanism through the two lead screws, so that the mowing platform can stably mow and ascend and descend in the horizontal plane.

Description

technical field [0001] The invention relates to the technical field of mowing platforms, in particular to an electric-controlled built-in liftable mowing platform. Background technique [0002] At present, most large-scale grassland weeding work power is provided by a tractor, and then connected to a mowing platform (hereinafter collectively referred to as cutting platform). The width of the platform mowing is generally about 2.4 meters. For the rear-mounted header, when it is combined with the tractor, except for the rigid pin connection in the middle connection, other auxiliary connections are connected by soft steel wires. This connection header needs to reach a certain level. Only the weight can ensure the stability of the entire mowing platform when mowing, and manual adjustment is required to adjust the mowing height. In addition, the power shaft from the tractor is directly connected to the gearbox, which makes it very troublesome to replace the belt on the mowing pla...

Problems solved by technology

[0002] At present, most large-scale grassland weeding work power is provided by a tractor, and then connected to a mowing platform (hereinafter collectively referred to as cutting platform). The width of the platform mowing is generally about 2.4 meters. For the rear-mounted header, when it is combined with the tractor, except for the rigid pin connection in the middle connection, other auxiliary connections are connected by soft steel wires. This connection header needs to reach a certain level. Only the weight can ensure the stability of the entire mowing platform when mowing, and manual adjustment is required to adjust the mowing height. In addition, the power shaft from the tractor is directly connected to the gearbox, which makes it very troublesome to replace the belt on the mowing platform; The power transmission of the entire header blades is driven by a gearbox. The number of blades is increased while the cutting width remains unchanged, which reduces the width of the header and reduces the weight a lot. However, the later maintenance is cumbersome. When the gears in the gearbox When damaged, it needs to be disassembled and replaced as a whole
