Swather

Abstract

The invention discloses a swather which comprises an engine, a main transmission system, a main rack, a walking box, an armrest frame, a supporting frame, a header, wheels, a main clutch control handle, a header clutch control handle and a gear shifting rod. The main transmission system is connected with a header driving mechanism through a transmission shaft, the header driving mechanism comprises a header clutch assembly, an eccentric arm assembly and a driving disc, and the clutch assembly comprises a driving shaft, a header clutch arm, a clutch bevel gear, a header transmission shaft, a transmission bevel gear and a first clutch claw. Independent lifting adjustment of a left armrest and a right armrest can be realized, so that individual requirements of different operators can be met;the structure of header lifting adjustment is simplified, so that the header lifting adjustment is more convenient and faster; header driving has a clutch function, and the wheels can independently walk; the transmission structure of a main transmission mechanism is changed to improve the transmission efficiency; and the problems of drooping and swinging of a large-span chain wheel and chain conveying mechanism of the header are avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a windrower. Background technique [0002] The harvesting and drying of straw crops such as rice, wheat, and cotton requires a lot of resources and manpower, and the efficiency is not high. As modern agriculture tends to be large-scale, large-scale, and mechanized, the windrowing machine came into being. [0003] The windrower is a kind of mechanical equipment that cuts crops and lays them flat in the field. It has very high production efficiency and is easy to use. Compared with large-scale agricultural machinery, the windrower has the advantages of small size, light weight, and flexible use. But existing windrower mainly has the following problems: [0004] (1) The armrest frame is the main component of the windrower, but most of the existing armrest frames cannot be adjusted, or the armrests on the left and right sides can only be adjusted synchronously, which...

AI Technical Summary

Problems solved by technology

[0004] (1) The armrest frame is the main component of the windrower, but most of the existing armrest frames cannot be adjusted, or the armrests on the left and right sides can only be adjusted synchronously, which cannot meet the individual needs of different operators. At the same time, the adjustment structure is complicated. Not easy to arrange

[0005] (2) As the core component of the windrowing machine, the header needs to be adjusted up and down in order to adapt to harvesting of different types and heights of crops. It is inconvenient to operate and has great limitations.

Because the existing windrower is not equipped with a clutch mechanism, when the engine is rotating, the header is always in working condition, resulting in waste of power and potential safety hazards

[0007] In addition, the drive of the existing header mainly depends on the universal joint. Since the universal joint is long and has a large rotation radius, it takes up a relatively large space, and the universal joint will cause damage to the crops during the rotation and swing process, and it is easy to Winding Causes Malfunction

[0008] (4) The belt drive mechanism is used to transmit the power of the engine to the header and the wheels, but the safety of the belt drive is low, and the rotating parts such as the exposed belt and pulley pose a safety threat to the operator of the machine; the rotation of the belt and pulley Parts are easy to stir into weeds or crops, causing crop loss for harvesting machinery, and it is necessary to manually clean up the debris, otherwise the rotating parts will be affected or even damaged due to too much entanglement of debris; belt drive requires additional Set up a tensioning structure or an adjusting structure, and the belt will stretch or break after a period of use, and must be replaced, otherwise it will slip or even fail to drive, which is inconvenient for maintenance

[0009] (5) The sprocket chain transmission mechanism on the header is too long. Under the action of its own gravity, the middle part of the chain is easy to sag, resulting in unstable transmission; during the transmission process, the chain is easy to swing greatly, causing interference and collision to other components , and even cause damage to the chain itself or cause safety accidents caused by the chain flying out. When using a large-span transmission chain, since the number of wheels or limit rods cannot be infinite, it can only support a few points of the chain, and most of the chain is still in a drooping or swinging state.
