Description
Technical Field

Background
The characteristics and pod distribution state of leguminous plants are greatly different from those of rice and wheat, the conventional axial-flow threshing device is directly adopted on a combine harvester for threshing once, and in order to meet the operation requirement of short threshing in a short time, a roller usually adopts high load and high rotating speed, so that leguminous seeds are hit greatly, and loss is easy to cause.
In addition, after harvesting is completed, the header at the front end of the existing combine harvester (see Chinese patent document with the application number of 201510505965.0 and 201910162868.4, namely a self-adaptive crop cleaning harvester) conveys the harvested crops to an independent threshing device through bridge conveying to complete threshing. In the face of the characteristics of high maturity, easy pod frying, low maturity and difficult threshing of bean plants, the threshing effect can be changed only by adjusting the rotating speed of the threshing cylinder and the threshing gap, and the long-standing problem is that: the threshing efficiency can be improved though the rotating speed is high and the gap is small, but the damage to seeds with higher maturity is easily caused, and the rotating speed is reduced and the gap is enlarged, but the seeds with lower maturity are difficult to separate from the stalks, so that the threshing effect is affected. Thus, how to combine the threshing requirements of seeds with different maturity becomes a pair of contradictions which are difficult to solve.

After the bean crop plants collected are fed into the bridge conveying mechanism with vibration pressure threshing by the combine harvester cutting table, in the conveying process of the conveyed vibration pressure belt, the bean crop plants are subjected to vibration and extrusion cooperation of the threshing plate and the threshing cylinder vibration pressure plate when being positioned at threshing intervals, seeds with higher maturity fall down in a dispute mode, fall onto the seed conveying belt from the leakage holes of the vibration pressure belt, are conveyed to the screening device under the action of the baffle plate, and the un-threshing plants and straws are continuously conveyed to threshing equipment of the combine harvester for threshing.
The invention is further perfected that the rotation translocation time of the adjacent threshing plates of at least one vibrating threshing cylinder is equal to the translation translocation time of the adjacent vibrating plates on the plant conveying vibrating belt. The relation between the rotating speed of the vibrating threshing cylinder and the feeding speed of the plant conveying vibrating belt can be controlled, so that the one-to-one correspondence between the threshing plate and the vibrating plate can be ensured when the threshing plate and the vibrating plate are adjacent, and the threshing plate can continuously and fully exert the matched extrusion function to strip off seeds with higher maturity.
Therefore, the device with the conveying function is reasonably improved into the bridge conveying vibration-pressure threshing device, seeds with higher maturity are threshed in advance in the bridge conveying process, and further threshing is completed by threshing equipment, so that the bridge conveying and the pre-threshing are combined ingeniously and organically, and the problem that the existing combine harvester is difficult to damage and high-efficiency threshing of the seeds with different maturity is solved properly.

The header A1 is connected with threshing equipment through a conveying mechanism A2 supported on a bridge bracket. These are substantially the same as the prior art and are not described.
As shown in fig. 2, the conveying mechanism A2 consists of an upper plant conveying vibration-pressing belt 2 and a lower grain conveying belt 4 which are positioned in the frame-type bridge-crossing bracket 1, and two vibration-pressing threshing drums 3 which are distributed at intervals are arranged above the grain conveying belt 4 of the conveying mechanism A2, so that a bridge-crossing conveying vibration-pressing threshing device is formed. As shown in fig. 3 and 4, the rotating shaft of the rear threshing cylinder is fixedly connected with a chain wheel 5 and a driving wheel 7 driven by a conveyer belt driving motor 8 and is in transmission connection with the chain wheel on the rotating shaft of the front vibrating and pressing threshing cylinder 3 through a chain 6.

As can be seen from fig. 1, the output end of the plant conveying vibration and pressing belt 2 is connected with the input end of the concave screen A7 through a declining connecting plate. The output end of the grain conveyer belt 4 is connected with the input end of the vibrating screen A8 through a grain connecting conveyer belt A4 driven by a driving motor A5.
As shown in fig. 7, the vibrating threshing cylinder 3 comprises a hollow rotary cylinder 3-2, and two ends of the rotary cylinder 3-2 are supported on the bridge bracket 1 through end plates 3-4 and a rotating shaft 3-5 and driven to rotate by a motor.
