Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Referring to fig. 1-19, the harvesting and bundling integrated machine comprises a bottom frame 1, a walking mechanism 2, a power transmission device 3, a harvesting device and a bundling device. Wherein the harvesting device comprises a header mechanism 4, a threshing mechanism 5 and a grain collecting mechanism 6. And the bundling device comprises a feeding mechanism 7, a pushing mechanism 8 and a bundling mechanism 9.

The bottom frame 1 and the running gear 2 are conventional, and the running gear is a self-propelled crawler structure, and the main functional components are driving wheels, other functional wheels such as guide wheels, tension wheels, and transmission crawler. The power transmission device 3 also belongs to the prior art, adopts a diesel engine, the power of the diesel engine which usually achieves power matching can be selected from 45KW, 48WK and 56KW, and for the reaping and bundling integrated machine of the embodiment, the power can meet the normal operation of each functional mechanism as long as the power can reach 45KW, and certainly, if more functional components are assembled on the reaping and bundling integrated machine, a diesel engine with higher power needs to be selected. For the power transmission device 3, power is manufactured by a diesel engine, the power is divided into two parts through transmission, one part provides walking power for the walking mechanism 2, the other part serves as working power, and the power transmission device is matched with transmission parts to provide power for the header mechanism 4, the threshing mechanism 5, the grain collecting mechanism 6, the feeding mechanism 7, the pushing mechanism 8 and the bundling mechanism 9.

The header mechanism 4 comprises a reel 41, a divider 42, a cutter 43, a header auger 44 and a feeding channel 45, and the header mechanism 4 has the main function of dividing grain crops into the working range of the header mechanism 4 and sending the grain crops into the header mechanism 4, and the straws of the grains (rice and wheat) are cut off and sent into the subsequent threshing mechanism 5 at a stable conveying speed and a conveying amount per unit time.

The reel 41 pulls the grain and the divider 42 cuts the grain into the working range, the lower part of the stalk is cut by the cutter 43, the cut grain is pushed into the feeding channel 45 by the cutting table auger 44, and the feeding channel 45 feeds the grain into the threshing mechanism 5.

For the header auger 44, compared to the prior art, it does not have a poke tooth. At present, the equipment of reaping at cereal, no matter be the harvester, combine, reaper-binder, all be carried by the header screw feeder to the cereal after the cutting, and almost all header screws are provided with and dial tooth 400a, it is provided with two to three groups along header screw feeder circumference usually to dial tooth 400a, every group sets up side by side along the axial of header screw feeder, usually set up three and more than three, the left and right sides that forms the group dials tooth 400a sets up left-handed blade and right-handed blade, at the during operation, the header screw feeder rotates will distribute the cereal of header screw feeder through left-handed blade and right-handed blade and assemble in the region that dials tooth 400a and locate, and dial tooth 400a with cereal and send to feed channel 45. The arrangement of the poking teeth 400a has become a technical inertia in the industry, which considers the poking teeth 400a as an essential part of the cutting table auger, and the conventional thinking is that if the cutting table auger does not have the poking teeth 400a or a structure similar to the poking teeth 400a, the grains cannot be better poked to the feeding channel by the cutting table auger.

In the present application, the header auger 44 has left-handed blades 441 and right-handed blades 442, the rotation directions of the left-handed blades 441 and the right-handed blades 442 are opposite, but the left-handed blades 441 and the right-handed blades 442 have the same lead, the same spread cut angle, and the same inner and outer diameters (the same length is asymmetric), and a first material-stirring blade 443 and a second material-stirring blade 444 are disposed between the left-handed blades 441 and the right-handed blades 442 and directly face the feeding channel 45, and the same first material-stirring blade 443 and the same second material-stirring blade 444 may also be disposed symmetrically. Thus, the header auger with the left-hand blade 441 and the second ejecting blade 444 is overlapped with the header auger with the right-hand blade 442 and the first ejecting blade 443.

The first stripping blade 443 is an extension of the right-hand blade 442 and the first stripping blade 443 does not intersect the left-hand blade 441, the second stripping blade 444 is an extension of the left-hand blade 441 and the second stripping blade 444 does not intersect the right-hand stripping blade 442.

Since the left-hand blade 441, the second stirring blade 444, the right-hand blade 442, and the first stirring blade 443 are symmetrical in structure, only the first stirring blade 443 will be described here, and the second stirring blade 444 is the same as the first stirring blade 443.

The first stirring blade 443, starting from the right end (i.e. the extending point of the right-handed blade 442) to the left end (i.e. the terminating end), has an increasing spreading cut angle, i.e. the first stirring blade 443 gradually spreads from the right end to the left end and gradually tends to be in a "horizontal" state, and obviously, the right-handed blade 442 transits to the first stirring blade 443, and the pushing direction of the grains tends to a longitudinal direction from a transverse direction, such an arrangement is favorable for pushing the grains into the feeding channel 45 at the first stirring blade 443 in a relatively longitudinal direction, and on the other hand, due to the gradually spreading structural arrangement of the first stirring blade 443, the channel 44a between the first stirring blade 443 and the right-handed blade 441 also has a width which is maximized when the channel reaches the left end of the first stirring blade 443, and therefore the grains pushed by the right-handed blade 442 are maximally gathered and pushed into the feeding channel 45 by the first stirring blade 443 . In fact, the channel 44b is formed between the left end of the first stirring blade 443 and the left-hand blade 441, when the grain conveying amount of the right-hand blade 442 is large, part of the grain can be branched off from the channel 44b, and the interconnected channels have a dynamic balance function.

Of course, the first material ejecting blade 443 and the second material ejecting blade 444 are not necessarily integrated with the right-handed blade 442 and the left-handed blade 441, and the first material ejecting blade 443 and the second material ejecting blade 444 may be separately manufactured and fixedly welded to the header auger 44.
