Abstract
The invention discloses a driven wheel overrunning clutch device for a harvester. The device comprises a driven shaft, a driven chain wheel which is arranged on the driven shaft in a sleeved mode, a sliding sleeve which is arranged on the driven shaft and can make axial movement, and a stopping part which is placed on the side, far away from the sliding sleeve, of the driven chain wheel and used for preventing the driven chain wheel from sliding in the axial direction. A clutch structure is arranged between the driven chain wheel and the sliding sleeve. By the aid of the clutch structure, when the driven chain wheel rotates, the sliding sleeve and the driven chain wheel can be combined so as to drive the driven shaft to rotate; when the driven chain wheel stops rotating and the driven shaft rotates continuously and synchronously, the sliding sleeve can be separated from the driven chain wheel. The driven wheel overrunning clutch device for the harvester is simple in structure and easy to manufacture, lowers impact, prolongs the service life of a chain and guarantees efficient work of the harvester.
Description
Technical field
The present invention relates to grain header technical field, relate in particular a kind of driven pulley overrunning clutch for grain header.
Background technology
The Chinese invention patent that patent publication No. CN102823378A, open day are 2012.12.19 discloses a kind of grain header, comprise running gear and power set, threshing unit, harvesting parts and the pulling parts of power are provided to running gear, also comprise levitation device, described levitation device is connected with running gear by coupling, and the height that this coupling can be realized levitation device regulates and transverse rotation; Described threshing unit, harvesting parts and pulling parts are positioned on levitation device.In technical scheme of the present invention, can make the center of gravity of grain header be born and not run-off the straight by levitation device by adaptation, reduce sagging amplitude, other weight is just no longer pressed in running gear, has reduced the gradient of running gear.
Present grain header, its power resources are in engine (being generally diesel engine), the power of diesel engine flows to driven shaft through chain, carried out the actions such as threshing by driven shaft, in actual work, we find that the chain of existing grain header is shorter service life, often rupture, and affect the normal work of grain header.
Summary of the invention
The object of the invention is for the deficiencies in the prior art part, a kind of driven pulley overrunning clutch for grain header is provided, in the service life that can improve chain, reduce and impact, ensure the efficient operation of whole grain header.
