Sugarcane tearing machine cutter

Abstract

The invention relates to the technical field of sugar industry, and provides a sugarcane tearing machine cutter. The cutter comprises a cutter head, a matrix and a forked tail portion which are siamesed, whose thicknesses are the same, and whose end portions are in flush butt joint, wherein the side face of the matrix is an oblique quadrangle with substantially-equal opposite sides; the cutter head is gradually narrowed, and the arc of the tail portion, far away from the matrix, of the cutter head forms an arc end face through transition; particularly, the middle of the tail portion of the cutter head is longitudinally provided with a slotting; the slotting is internally embedded with a wear-resistant alloy block; the width of the slotting is 1 / 3 to 5 / 6 of the thickness of the cutter head; the distance from the midpoint of the arc end face to the slotting end is greater than the thickness of the cutter head; the thickness of the alloy block is adapted to the slotting; the bottom face of the alloy block directly faces the bottom slot face of the slotting, and the side connecting faces of the alloy block are respectively abut to the side slot faces of the slotting; the other faces of the alloy block are crushing working surfaces which are 0 to 10 mm higher than the surface of the corresponding position of the cutter head; optimally, an auxiliary working surface, on the outer side of the slotting, of the cutter head is firmly adhered to a wear-resistant alloy layer with the thickness of less than 2 mm. The cutter provided by the invention has the characteristics of good wear resistance and impact resistance, and the service life of the tearing machine cutter can be prolonged.

Description

technical field [0001] The invention relates to the technical field of the sugar industry, in particular to a sugarcane shredder cutter used in a sugarcane sugar factory. Background technique [0002] Sugarcane crushing is an important process in the pressing workshop of a sugarcane sugar factory, and the sugarcane tearing machine is an important equipment for the pretreatment of sugarcane crushing. The cutter installed on the knife roller is the key working part of the tearing machine. The knives on the knife roller are arranged in a single or double helix row, and the high-speed rotation of the knife roller drives the knife to cut and crush the sugarcane. In recent years, with the popularization and application of sugarcane mechanized harvesting and the increase in the use of mechanized grasping machines for sugarcane loading, the proportion of entrained sand and gravel in sugarcane has increased significantly, which has aggravated the wear of sugarcane tearing machine too...

AI Technical Summary

Problems solved by technology

However, with the popularization and use of mechanized harvesting and mechanical grabbing machine loading in sugarcane sugar-producing areas, the coarse sand carried in the sugarcane has increased significantly. The impact often causes the cracking and peeling of the wear-resistant alloy layer of the cutter head

Especially the tool using cemented carbide has high hardness and high brittleness. When the knife head encounters debris such as sand and stones, the tip of the knife is brittle and broken, and the cane knife that loses the protection of the knife tip will quickly wear out and fail.

Therefore, the current tearing machine knives on the market cannot well solve the problems of brittleness, fast wear, and short service life of the knives. Therefore, it is necessary to develop a durable tearing machine with high wear resistance and good impact resistance. Knives have become a technology that the sugar industry needs to break through
