Abstract
The utility model relates to a lower cutting knife and a transmission device of a harvester. The lower cutting knife and the transmission device of the harvester comprise a lower cutting knife seat (2). A set of cutting knife bodies (3) and a set of cutting knife transverse plates (4) are connected on the lower cutting seat (2), wherein the cutting knife transverse plates (4) are matched with the cutting knife bodies (3), the lower cutting knife seat (2) is connected with a set of connecting rods, an eccentric shaft (7) is connected on a connecting rod which is arranged at the outermost position, and a belt wheel (9) and a cardan joint (6) are arranged on the eccentric shaft (7). The lower cutting knife and the transmission device for the harvester lengthen the cutting knife seat, increase the number of the cutting knives, and can achieve an ideal effect of no residual in the process of crop harvesting. According to the lower cutting knife and the transmission device of the harvester, a chain wheel which is welded on the eccentric shaft in the prior art is replaced with the belt wheel which is connected with the eccentric shaft through a flange, and therefore the belt wheel is easy to replace and convenience is brought to machinery maintenance. Due to the fact that the belt wheel is connected on a tensioning wheel of the harvester through a belt, when harvesting is not needed, such as cutter lifting or cutter dropping, the cutting knives can be stopped to move through a transmission mechanism of the tensioning wheel, and an ideal effect can be achieved when lodging crops are harvested.
Description
Technical field
The utility model relates to a kind of farm machinery, particularly a kind of following cutter and transmission device of grain header.
Background technology
Grain header is the machinery of integrated harvesting crops.Disposablely finish harvesting, threshing, and grain is focused on repository, by conveyer belt grain is being transported to a kind of machinery on the transport vehicle then.The kind of grain header mainly contains: portable grain header, portable grain header are divided into two kinds of side hanging and backpacks again; The hand-held grain header; Horizontal ceding of Taiwan grain header; Standing header grain header etc.Full feeding and feed reaper.Upper strata cutter and lower floor's cutter width in the existing full feed type combine are inconsistent, and lower floor is shorter, and this easily produces residual when harvesting, cause waste, in operation process, lower floor's cutter of machine is in running order always, and there is inconvenience in this crops to the harvesting lodging.Through extensively retrieval, still find no relevant technical scheme.
The utility model content
The purpose of this utility model is residual in order to solve the easy generation when harvesting crops of present stage grain header, lower floor's cutter is kept in motion always during harvesting, there are shortcomings such as inconvenience in crops harvesting to lodging, and following cutter and the transmission device of a kind of grain header that proposes.
To achieve these goals, the utility model has adopted following technical scheme: following cutter and the transmission device of a kind of grain header that the utility model provides, comprise cutter seat down, pass through stationary knife plate and one group of cutter transverse slat at following cutter seat, connect one group of cutter at the stationary knife plate, cutter and cutter transverse slat match.Following cutter seat is connected with the front end of three connecting rods, connects a holder respectively in the rear end of connecting rod, and wherein the rear end of connecting rod is by the centre bore turning cylinder that is connected, and turning cylinder is connected by the spline in the centre bore of spline and eccentric shaft.Be connected in fixed muffle at eccentric shaft, fixed muffle connects universal joint, and universal joint is connected with the stationary knife plate with connecting rod by swing arm, it is characterized in that: described eccentric shaft opposite side connects belt pulley.
On the basis of technique scheme, following further technical scheme can be arranged: described cutter seat down outwards is provided with the extension, the cutter transverse slat that connects one group of cutter and match with cutter by the stationary knife plate on the extension.
Described belt pulley is connected a side of eccentric shaft, and eccentric shaft is provided with flange, and belt pulley and flange are connected, and belt pulley is connected with the regulating wheel of grain header by belt.
Advantage of the present utility model: the device for prolonging that the utility model provides the length of cutter seat, increased the quantity of cutter, it is clean to reach harvesting when harvesting crops, and does not have residual ideal effect.The sprocket wheel that this device will originally weld at eccentric shaft changes the belt pulley that connects by flange into, and belt pulley is changed simple, provides convenience to flight-line maintenance.Belt pulley is connected to by belt on the regulating wheel of grain header, when not needing harvesting as cutter lifting or falling cutter, can make the cutter stop motion by the regulating wheel transmission mechanism, and this can reach more desirable effect to when gathering in the crops of lodging.
