Embodiment 1

[0040] A threshing structure of an L-shaped horizontal and vertical axial flow full-feed combine harvester, comprising a threshing frame, a vibrating screen 10 arranged on the threshing frame, a blower 7 and an intermediate conveying 1 connected to the upper front end of the threshing frame, The threshing frame is also provided with a threshing drum connected with the rear end of the intermediate conveying 1, and the threshing drum includes a horizontal axial flow drum 2 and a vertical axial flow drum 3 connected in communication, and the horizontal axial flow drum 2 and the vertical axial flow drum 2 are connected to each other. The cylinders 3 are vertically L-shaped. The blower 7 is arranged obliquely below the front side of the vibrating screen, and the blower 7 blows air to the vibrating screen from bottom to top and from front to back.

[0041]Both ends of the horizontal axial flow drum 2 are respectively connected to the intermediate conveying 1 and the longitudinal axi...

Embodiment 2

[0048] The difference from the above embodiment is that the two ends of the vertical axial flow drum 3 are respectively connected to the intermediate conveying 1 and the horizontal axial flow drum 2 . The length of the horizontal axial flow drum (2) is 1500 mm, and the length of the vertical axial flow drum (3) is 1800 mm.

Embodiment 3

[0050] The difference from the above embodiment is that the angle between the projection of the first baffle to the horizontal plane where the shaft-44 axis line is located and the shaft-44 axis line is 25 degrees, and the middle baffle is Two arranged in parallel, the included angles between the projection of the middle deflector and the turning deflector 62 to the horizontal plane where the axis line of the rotating shaft-44 is located and the axis line of the rotating shaft-44 are respectively 45 degrees and 135 degrees , the length of the horizontal axial flow drum 2 is 1300mm, and the length of the vertical axial flow drum 3 is 1500mm.

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a threshing structure of an L-shaped horizontal and longitudinal axial flow full-feeding combine harvester. The threshing structure comprises a threshing rack, a vibrating screen arranged on the threshing rack, an air blower and a middle conveyor connected on the upper portion of the front end of the threshing rack, a threshing drum communicated with the rear end of the middle conveyor is arranged on the threshing rack and comprises a horizontal axial flow drum and a longitudinal axial flow drum which are in communicated connection and perpendicular to each other to be L-shaped, two ends of the horizontal axial flow drum are connected with the middle conveyor and the longitudinal axial flow drum respectively, and the middle conveyor and the longitudinal axial flow drum are arranged on two sides of the horizontal axial flow drum respectively. The threshing structure is large in feeding quantity and high in operating efficiency during harvesting, connection of a threshing, cleaning and selecting drum and a discharging port of the middle conveyor is smooth and small in loss, crops in the horizontal axial flow drum are good in threshing, cleaning and selecting effect, and a notch board screen is large in separating area.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a threshing structure of an L-shaped horizontal and vertical axial flow full-feed combine harvester. Background technique [0002] At present, there are two main threshing and cleaning structures of crawler harvesters in China: the first single horizontal axial flow drum structure, that is, a horizontal drum is arranged at the threshing position, which is the oldest threshing method. The second type of single vertical axial flow drum structure, the drum length is long. [0003] The advantages and disadvantages of the above two structures are as follows: [0004] Structure 1. The advantages of single transverse axial flow drum are simple structure, convenient manufacture, and low cost. The disadvantage is that it can only meet the basic threshing function; the threshing and cleaning effect is limited by the width of the header, and it is relatively difficult to dea...
