The utility model discloses still further perfect is, the length that threshing plate stretches out towards the direction of rotation is good at the length that the contrary direction of rotation stretches out.
The utility model discloses it is still further perfect, the small opening is the strip that extends along sticky tape length direction, and the interval equipartition is on sticky tape width direction.
A further refinement of the present invention is that the baffle is L-shaped.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Example one
The gap bridge conveying vibration-pressing threshing device of the combine harvester of the embodiment is shown in fig. 1 to 6, and comprises a conveying mechanism supported on a frame-type gap bridge support 1, wherein the conveying mechanism consists of an upper plant conveying vibration-pressing belt 2 and a lower seed conveying belt 4, and two vibration-pressing threshing rollers 3 which are distributed at intervals are arranged above the seed conveying belt 4 of the conveying mechanism. Wherein the cylinder 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 cylinder shaft of the front vibration-pressing type threshing cylinder 3 through a chain 6.
The plant conveying vibration pressing belt 2 is composed of vibration pressing belts 2-2 surrounding driving roller shafts 2-1 at two ends, and the vibration pressing belts 2-2 are composed of hollow rubber belts 2-2-2 distributed with leakage holes and rubber flexible vibration pressing plates 2-2-1 distributed at intervals in the length direction of the rubber belts. The weeping holes are strips extending along the length direction of the adhesive tape and are uniformly distributed in the width direction of the adhesive tape at intervals, so that grains can be fully screened onto the grain conveying belt.
The kernel conveyer belt 4 is composed of a rubber belt 4-2 which is encircled on the driving rollers 4-1 at the two ends and L-shaped baffle plates 4-3 which are distributed at intervals in the length direction of the rubber belt 4-2.
The vibration-pressure threshing cylinder 3 comprises a hollow rotary cylinder 3-2, two ends of the rotary cylinder 3-2 are supported on the gap bridge support 1 through end plates 3-4 and rotating shafts 3-5, and the rotary cylinder is driven by a motor to rotate. Four groups of connecting tooth rows 3-3 extending in the radial direction are uniformly distributed on the outer circle of the rotary drum 3-2 in the circumferential direction, each group of connecting tooth rows 3-3 consists of five tooth columns uniformly distributed in the axial direction, and the outer ends of the connecting tooth rows 3-3 are fixedly connected with tangential rubber threshing plates 3-1. The length of the threshing plate 3-1 extending towards the rotating direction is longer than the length of the threshing plate extending towards the reverse rotating direction, so that crops can be extruded by larger and smaller flexible parts, and the threshing effect is better.
The rotation translocation time of the adjacent threshing plate 3-1 of the vibration pressing type threshing cylinder connected with the driving wheel 7 in the embodiment is equal to the translation translocation time of the adjacent vibration pressing plate 2-2-1 on the plant conveying vibration pressing belt, and the transmission ratio of the rear threshing cylinder and the two front threshing cylinders is larger than 1 unconventionally, so that the threshing plate of the front threshing cylinder and the vibration pressing plate are in random corresponding relation, the relation between the rotating speed of the rear vibration pressing type threshing cylinder and the feeding speed of the plant conveying vibration pressing belt is controlled, the threshing plate of the threshing cylinder and the vibration pressing plate are ensured to be in one-to-one correspondence when being adjacent, crops are extruded randomly and extruded orderly, the vibration extrusion threshing effect of mutual organic combination is fully exerted, and the seed grain effect is better. In the second time, the threshing plate does not vibrate, when the plant is piled up on the plant conveying vibration belt and is conveyed, the vibration-pressing threshing roller rotates, the linear velocity direction of the lower end of the vibration-pressing threshing roller is consistent with the conveying direction of the plant conveying vibration belt, a threshing gap (for example, 10 cm) between the vibration-pressing threshing roller and the vibration belt is formed, the hollowed-out adhesive tape has certain elasticity, the piled thickness of the plant is larger than the gap, the vibration-pressing threshing roller compresses grains in the rotating process, the hollowed-out adhesive tape can jump up and down regularly under the pressure action, so that the relative vibration in the operation process is generated, the threshing is completed under the combined action of the vibration and the extrusion force of the threshing plate, and meanwhile, due to the existence of the relative vibration, grains are easier to fall from the hollowed-out adhesive.
