Example Embodiment
[0023] Example one
[0024] The combine harvester of this embodiment crosses the bridge to convey the vibration pressure threshing device such as Figure 1 to 6 As shown, it includes a conveying mechanism supported on the frame-type bridge support 1. The conveying mechanism is composed of an upper plant conveying vibration pressure belt 2 and a lower seed conveying belt 4, and two grain conveying belts 4 are installed above the conveying mechanism Vibratory pressure threshing drum 3 distributed at intervals. The barrel shaft of the rear threshing drum is fixedly connected to the sprocket 5 and the driving wheel 7 driven by the conveyor driving motor 8, and is connected to the sprocket on the barrel shaft of the preceding vibration-pressure threshing drum 3 through the chain 6 in transmission.
[0025] The plant conveying vibration pressure belt 2 is composed of a vibration pressure belt 2-2 that surrounds the driving roller shaft 2-1 at both ends, and the vibration pressure belt 2...

The invention relates to a bridge-crossing conveying vibrating-pressing threshing device of a combine harvester, and belongs to the technical field of agricultural machinery. A conveying mechanism of the device is composed of an upper plant conveying vibrating-pressing belt and a lower grain conveying belt. The conveying mechanism is provided with at least one vibrating-pressing threshing cylinder; the plant conveying vibrating-pressing belt is composed of a vibrating-pressing belt which surrounds driving roller shafts at the two ends, and the vibrating-pressing belt is composed of a hollow-out adhesive tape which is provided with leakage holes and flexible vibrating-pressing plates which are uniformly distributed in the length direction of the adhesive tape at intervals. The grain conveying belt is composed of a rubber belt surrounding driving rollers at two ends and L-shaped baffles distributed in the length direction of the rubber belt at intervals; the vibrating-pressing threshing cylinder comprises a rotating roller, and connecting tooth rows extending in the radial direction are uniformly distributed on the outer circumference of the rotating roller; the outer ends of the connecting tooth rows are fixedly connected with tangential threshing plates; threshing intervals are formed between the threshing plates and the vibrating-pressing plates adjacent to the threshing plates. According to the device, the problem that an existing combine harvester cannot achieve non-destructive and efficient complete threshing of grains different in maturity degree is well solved.
Description
technical field [0001] The invention relates to a mechanism of a harvester, in particular to a bridge-transporting vibration-pressure threshing device for a combine harvester, which belongs to the technical field of agricultural machinery. Background technique [0002] According to the applicant's knowledge, after harvesting, the header at the front end of the existing combine harvester transports the harvested crops to an independent threshing chamber by crossing the bridge to complete threshing. Due to the different maturity of crops, whether it is a one-time threshing with a single vertical axial flow drum or two horizontal axial flow drums, the threshing effect can only be changed by adjusting the speed of the threshing drum and the threshing gap. The problem is: Although high speed and small gap can improve the cleaning rate, it is easy to cause damage to the mature grains. Although reducing the speed and increasing the gap can effectively avoid damage, it is difficult ...
