Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] Such as figure 1 , 2 , 3, 4, and 5, a cutting and cross-flow grain combine harvester threshing device includes a threshing chamber wall 1, an axial flow drum cover plate 2, a cutting flow drum 3, a cutting flow concave plate 4, and a horizontal axial flow drum 5, Movable concave plate 6, auger 7. Taking the vehicle’s traveling direction during the harvesting process of the harvester as a reference, the cutting flow drum 3 is located in the right front of the threshing chamber, and is used for pre-acceleration and partial threshing of the grain transported across the bridge. The cutting ...

Abstract

The invention discloses a threshing device of a tangential-transverse flow grain combine harvester. The threshing device comprises a threshing chamber wall, an axial flow roller cover plate, a tangential flow roller, a tangential flow concave plate, a transverse axial flow roller, a movable concave plate and an auger. The rotating speed of the tangential flow roller is between the bridge crossingspeed and the rotating speed of the axial flow threshing roller, crop acceleration and partial threshing are achieved in the tangential flow roller, the speed of crops entering the transverse axial flow roller is increased, partial threshing is conducted on the crops, and the burden of a subsequent threshing system is relieved; the transverse axial flow roller is divided into three sections, the threshing capacity is high, the threshing gap of the axial flow concave plate is adjustable, operation is flexible, and the requirements of different feeding amounts are met. The purposes of smooth feeding, loss rate reduction and threshing efficiency improvement are achieved, the feeding amount of the grain harvester is increased, and the compactness of the structural design is achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a threshing device for a cross-flow grain combine harvester, which can be widely used in high-performance harvesting operations of grains such as wheat and rice. Background technique [0002] Threshing is one of the key links in grain harvesting. The threshing device is the carrier for harvesting on the grain combine harvester. Its performance is an important parameter to measure the quality and efficiency of a grain combine harvester. The most concerned performance indicators. The basic function of the threshing device is to remove the grain grains from the ears, and secondly to separate the grain grains in the extraction mixture (grain grains, short stalks, chaff and other debris). [0003] In the structure of the existing tangential flow drum + horizontal axial flow drum composite threshing device, the tangential flow threshing drum is mostly of the bar type, a...
