Embodiment Construction

[0016] Such as figure 1 , figure 2 As shown, the longitudinal axial flow threshing device 1 is placed above the underframe 4 on the walking device 3 of the full-feed combine harvester.

[0017] The threshing device is provided with a threshing cylinder 12 and a concave screen 13 arranged at the bottom of the threshing cylinder 12 and wrapped outside the threshing cylinder 12 from below. The top cover 14 is covered on the upper end of the concave screen 13. The threshing assembly formed by the concave plate sieve 13 and the top cover 14 is vertically arranged in the harvester, the front is low and the rear is high, and the concave plate sieve 13 is used as the primary separation screen. The bottom of the described threshing assembly is provided with a cleaning vibrating screen 15 arranged longitudinally along the harvester, the threshing assembly is inclined to the cleaning vibrating screen 15, the front end of the threshing assembly is close to the cleaning vibrating screen,...

Abstract

The invention provides a longitudinal axial flow threshing device. The device is provided with a threshing cylinder and a concave plate screen arranged at the lower part of the threshing cylinder and wrapped outside the threshing cylinder from the lower part; a top cover is covered at the upper end of the concave plate screen; a threshing assembly consisting of the threshing cylinder, the concave plate screen and the top cover is longitudinally arranged in a harvester in a mode of low front and high back; a cleaning vibrating screen arranged along the longitudinal direction of the harvester is arranged below the threshing assembly, the threshing assembly is inclined to the cleaning vibrating screen, the front end of the threshing assembly is close to the cleaning vibrating screen, and the rear end of the threshing assembly is far from the cleaning vibrating screen; and a guide plate is arranged between the concave plate screen and the cleaning vibrating screen, the guide plate is arranged along the longitudinal direction of the harvester in a mode of low front and high back, the upper end of the guide plate is positioned at the tail end of the concave plate screen, and the lower end of the guide plate is positioned at the upper part of the middle section of the cleaning vibrating screen. According to the device, under the condition that the main structures of the cleaning vibrating screen and the threshing cylinder are not changed, the treatment quantity of the front section of the cleaning vibrating screen can be improved, the treatment capacity of the cleaning vibrating screen can be improved, and the work efficiency of the harvester can be improved.

Description

technical field [0001] The invention relates to the field of a threshing device in a vertical axial flow full-feed combine harvester. Background technique [0002] The full-feed vertical axial flow combine harvester is named after the axial direction of the threshing drum of the threshing device is consistent with the walking direction of the harvester. Compared with the transverse axial flow threshing device perpendicular to the running direction of the harvester, it has higher threshing capacity. As a vertical axial flow combine harvester, the threshing device has a structure in which the threshing drum and the lower vibrating separator are arranged in parallel and placed horizontally, such as the structure disclosed in Patent No. ZL200920118544.2. [0003] In addition, there is a double-drum structure in which the main threshing drum is parallel to the auxiliary drum re-extraction structure and is arranged in parallel with the lower vibrating separation screen, such as t...
