Cutting device for sugarcane end breakage prevention

Abstract

The invention provides a cutting device for sugarcane end breakage prevention. The cutting device comprises a motor, the bottom of the motor is rotatably connected with a spindle, a knife disc is fixedly connected below the spindle, cutting knives fixedly connected around the bottom of the knife disc, an inner groove is formed in one side of the bottom, away from the spindle, of each cutting knife, a tooth-shaped block is fixedly connected on the inner side of each inner groove, a bearing is fixedly connected below the spindle, a fixing disc is fixedly connected on one side, back to the spindle, of the bearing, and both the bearing and the fixing disc are positioned below the knife disc. Sugarcane is cut through a cutting block above a retaining plate, the bottom of the sugarcane can be supported through a semicircular fixing block, and the lower side of the sugarcane is enabled to receive shearing force opposite to the cutter; the cutting block is semicircular, and cross section of the cutting block is triangular, a position, receiving maximum shearing force, of the sugarcane can be cut so as to cut the lower side of the sugarcane, so that cutting efficiency of the sugarcane can be improved, and sugarcane end breakage can be reduced effectively, and convenience is brought to harvesting of the sugarcane.

Description

technical field [0001] The invention belongs to the technical field of sugarcane cutting, and more specifically relates to a sugarcane cutting device. Background technique [0002] Existing sugarcane harvesting has generally adopted mechanized equipment to harvest sugarcane, and the rotary cutting knife in the cutting device is used to cut off the sugarcane root. When the sugarcane is cut, the sugarcane has no fixed limit structure, resulting in When the sugarcane is in contact, it is easy to force the back surface of the sugarcane, resulting in splitting and broken heads of the sugarcane, which will affect the germination rate and yield of the sugarcane in the next year. The sugarcane is easy to be in contact with the cutter again, which will cause splitting and broken heads of the sugarcane, which has certain limitations. [0003] Therefore, in view of this, the inventor has been adhering to many years of rich experience in design, development and actual production in thi...

Problems solved by technology

[0004] A cutting device for sugarcane anti-breakage, to solve the problem that the sugarcane has no fixed position-limiting structure when the sugarcane is cut, which makes the back surface of the sugarcane easily damaged when the cutting knife contacts the sugarcane. force, resulting in splitting and head breaking of sugarcane, which will affect the germination rate and yield of sugarcane in the next year. Splitting and head breaking occur, with certain limitations
