Sugarcane cutting off device and sugarcane harvester

Abstract

The invention provides a sugarcane cutting off device which comprises two cutting off tool cylinders (2) arranged side by side. The cutting off tool cylinders (2) are provided with cutting off tool blades (22) respectively, sugarcane can be cut off when the cutting off tool blades (22) are aligned, the driving end of each cutting off tool cylinder (2) is connected with a driving device (1), and the two cutting off tool cylinders (2) can rotate synchronously through the driving devices (1). According to the sugarcane cutting off device, due to the fact that each cutting off tool cylinder is connected with the corresponding driving device, the two cutting off tool cylinders are consistent in step in the rotating process, the phenomenon that gear abrasion is caused due to the fact that a main cutting tool drives an auxiliary cutting tool, and consequently delay occurs in the rotating process of the cutting off tool cylinders is avoided. The phenomenon of stagger generated when the cutting off tool blades are aligned is avoided, the alignment of the cutting off tool blades is more accurate in the cut off process of the sugarcane, and the probability of stripping phenomena is reduced. The invention further provides a sugarcane harvester.

Description

technical field [0001] The invention relates to the field of heat dissipation of agricultural machinery, in particular to a sugarcane cutting device and a sugarcane harvester. Background technique [0002] Existing sugarcane section cutting device on the market all is to drive auxiliary cutter by a main cutter motor by gear meshing, sugarcane is carried out sectioning. The problem with this device is that during the meshing process of the gear that drives the auxiliary cutter to rotate, due to the gap between the gear teeth due to friction loss, it cannot be synchronized with the main cutter to generate a time delay when rotating, and thus cannot be precisely rotated. Cutting off the sugarcane will cause peeling of the cut sugarcane due to inconsistent knife edges on both sides. Contents of the invention [0003] In order to overcome the above-mentioned technical problems, the present invention provides a sugarcane cutting device to improve the peeling phenomenon existing...
