Description
Technical field
The present invention relates to a kind of farm machinery, particularly the flexible standing grain device of dialling of a kind of asynchronous air-sweeping type flexible bionic.
Background technology
Dial standing grain device and be widely used in agricultural harvesting machinery, in wheat, paddy rice, Soybean and Other Crops results process, all need to push crop to cutter or feeding mouth by dialling standing grain device, crop stem is cut off or crop fringe head is cut to harvesting.Conventional Shift Computation standing grain device is mainly comprised of bat, spoke, wheel hub, rice crop-poking wheel axis, by the rotation of dialling standing grain device, pushes crop to rear, because bat hardness is large, causes a large amount of crop kernel spatter losses during High Rotation Speed operation.In semi-feeding type harvest machinery, the radially operation length of bat immobilizes, cause to dial standing grain height and feed the degree of depth and can not reach maximum simultaneously, when bat is dialled the increase of standing grain operation height, need to increase the spoke length of dialling standing grain device simultaneously, cause on the one hand the appearance and size of dialling standing grain device to increase, cause manufacturing processing cost and improve, cause on the other hand bat and feeding mouth to interfere; And reduce spoke degree, can reduce and dial standing grain operation height, cause dial standing grain scope reduce, to crop fringe head directly impact large, seed spatter loss is large, simultaneously fringe head can not completely enter feeding mouth and produce that harvesting is imperfect, harvesting omits loss and improves etc.
For solving seed, impact spatter loss serious problems, foreign scholar was once installed the device of jet-stream wind additional on cutter in the seventies in last century, by speed, being 10m/s tells air-flow, from the front lower place of cutter, to ceding of Taiwan rear portion, carry, test shows 150mm place ejection air-flow before cutter, for the standard ceding of Taiwan, can reduce yield loss 35%, but this device need to be equipped with fan blower, cause power consumption increase, the manufacturing cost of complete machine to improve.For solving the contradictory problems of dialling standing grain height and feeding height, domestic scholars once adopted the turbine and worm gearbox mode of setting up, the operation height that coordinates cam structure to realize bat regulates, but this scheme bat height change scope only has minimum and two numerical value of peak, can not realize group standing grain height and be changed to the continuity of peak by minimum, thereby cause crop stem to rock seriously and the seed that splashes.
Take a broad view of the present situation of above-mentioned group of standing grain device, be badly in need of a kind of group of standing grain process to crop impact little, dial standing grain height and feeding degree of depth continuity is adjustable, simple and compact for structure, complete machine low cost of manufacture dial standing grain device.
Summary of the invention
The object of this invention is to provide the flexible standing grain device of dialling of a kind of asynchronous air-sweeping type flexible bionic, the flexible group standing grain device of this asynchronous air-sweeping type flexible bionic has overcome the defect of prior art, its group of standing grain contact impact is little, dial standing grain operation height and feed the degree of depth adjustable continuously, dial the loss of standing grain process crop kernel few, crop kernel surface damage is little, simple and compact for structure, dials standing grain operation overall efficiency high.
