Embodiment 1

[0033] like image 3 and Figure 4 Commonly shown, a combine harvester with a stalk chopper includes a frame 1 and a longitudinal axial flow drum 2 rotatably mounted on the frame 1, and the machine below the grass outlet 21 of the longitudinal axial flow drum 2. The frame is provided with a stalk chopper 3, and the stalk chopper 3 includes a moving knife shaft 32 driven by a transmission device 31. The axial direction of the moving knife shaft 32 is arranged horizontally. 33; the rotation direction of the moving knife 33 is inconsistent with the rotation direction of the longitudinal axial flow drum 2, which is beneficial to chopping the stalks, and the length of the stalks can meet the needs of returning the stalks to the field, and can spread the entire cutting width without causing uneven thickness.

[0034] The stalk shredder 3 also includes a fixed knife support 34, and the fixed knife support 34 is provided with some fixed knives 35, and the fixed knives 35 are arranged...

Embodiment 2

[0041] This embodiment is basically the same as Embodiment 1, the difference is that, as Figure 5 As shown, the intermediate shaft 312 is disposed above the vertical axial flow drum 2 .

Abstract

The invention discloses a combine harvester with a stem chopper, and belongs to the technical field of agricultural machinery. The combine harvester comprises a rack and a longitudinal axial flow roller, wherein the stem chopper is arranged on the rack below the rear part of a straw outlet of the longitudinal axial flow roller; the stem chopper comprises a moving cutter shaft driven by a transmission device, a fixed cutter bracket, a chopper cover and a spreader; the axial direction of the moving cutter shaft is set along the transverse direction; a plurality of moving cutters are distributed on the moving cutter shaft; a plurality of fixed cutters are arranged on the fixed cutter bracket and are arranged below the front parts of the moving cutters; the fixed cutters and the moving cutters are staggered and arranged along the axial direction of the moving cutter shaft; the moving cutters are located in the chopper cover; the chopper cover and the fixed cutter bracket are respectively located at two sides of the moving cutter shaft; the upper end of the spreader is articulated with the bottom of the chopper cover; and a limiting device is arranged between the spreader and the rack above the stem chopper. The combine harvester is good in stem chopping effect and convenient to transport.

Description

[0001] Solemnly declare [0002] The present invention claims the priority of the Chinese invention patent application with the application date of September 22, 2015, the application number CN201510607159.4, and the name "Combine Harvester with Stalk Chopper". technical field [0003] The invention belongs to the technical field of agricultural machinery, in particular to a combine harvester with a stalk chopper. Background technique [0004] At present, under the requirements of national policies and regulations, combine harvesters should be equipped with stalk choppers to return stalks to the field. [0005] like figure 1 and figure 2 As shown together, the mainstream combine harvester model in the Central Plains market is a half-drum "horizontal axial flow" model, which includes a header 100, a bridge device 200, a threshing and separating device 300, and a stalk chopper 400. The threshing and separating device 300 includes a transverse axial flow drum 301 . Due to ...
