Abstract

The invention discloses a stubble cleaning assembly of a corn harvester. A moving knife shaft is supported onto two vertical plates through bearings and bearing blocks, a plurality of flail knife blade units are arranged on the moving knife shaft along the axial direction of the moving knife shaft, each flail knife blade unit comprises two groups of flail knives which are uniformly distributed incircumference, and each group of flail knives consists of a first bent flail knife, a second bent flail knife and a straight flail knife located between the corresponding two bent flail knives; a locating plate is arranged in front of a row of flail knife blade units, multiple groups of fixed blades are mounted on the locating plate, and each group of fixed blades comprises a left fixed blade anda right fixed blade; when the moving knife shaft rotates, in the same group, one fixed blade is located between the corresponding first bent flail knife and straight flail knife of the corresponding flail knife blade unit, and the other fixed blade is located between the corresponding straight flail knife and second bent flail knife of the corresponding flail knife blade unit. The stubble cleaningassembly of the corn harvester is simple in structure, easy to assemble and small in space usage, and straw can be thoroughly and completely crushed at a relatively low revolution rate, so that the stubble-cleaned straw is short and broken, the energy consumption is lowered, the stubble cleaning effect is ensured, and the stubble cleaning assembly is applicable to various types of maize stalks.

Description

technical field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a stubble removal assembly on a corn harvester. Background technique

[0002] The corn harvester is an operating machine that uses machinery to complete corn stalk cutting, ear picking, peeling, threshing, straw treatment, and even rotary plowing of the land after harvesting when the corn is mature, according to its planting method and agronomic requirements. The stubble removal (that is, crushing the corn stalks and returning them to the field) assembly on the existing corn harvester directly interrupts the corn stalks by the high-speed rotating straight knife for stubble removal, but because of the high speed and the straight knife, the straw after stubble removal is longer , and consumes a lot of power and takes up a lot of space, it is only suitable for large-scale plain corn harvesting.

Embodiment Construction

[0021] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0022] Such as figure 1 As shown, two vertical plates 8 on the left and right are fixedly installed on the frame, and these two vertical plates 8 are parallel to each other. The moving knife shaft 1 passes through two vertical plates 8 vertically, the left end of the moving knife shaft 1 is supported on the left vertical plate 8 through a bearing and a bearing seat 9, and the right end of the moving knife shaft 1 is supported by another set of bearings and a bearing seat 9 On a vertical board 8 on the right side. One end of the moving knife shaft 1 is fitted with a duplex sprocket 12, and the duplex sprocket 12 is connected with the engine or the gearbox of the corn harvester through a chain transmission mechanism.

[0023] Such as Figure 1 to Figure 5 As shown, a plurality of throwing blade units are arranged along its axial direction on the moving knife...
