Root cutter for sugarcane harvester with soil leakage function

Abstract

The invention provides a sugarcane harvester root cutter having a soil leaking function. The sugarcane harvester root cutter comprises a pair of left rotating shaft and right rotating shaft which are driven by a transmission mechanism to rotate in opposite directions; flange plates at the lower ends of the left rotating shaft and the right rotating shaft are fixedly provided with one circular cutter head each, wherein each circular cutter head is provided with four hollow-out sector grooves uniformly in the middle and four cutting blades are installed fixedly in cruciform symmetry under separating rib plates of the sector grooves of each circular cutter head; the rod portion of each of the left rotating shaft and the right rotating shaft is symmetrically provided with four segments of rotating shaft lifting feeding strips, wherein two spiral lifting feeding strips connected to the lower ends of two symmetrical rotating shaft lifting feeding strips are wound around the outer ring of the corresponding rotating shaft in the rotation direction thereof and are fixed on the rear edges of the sector grooves of the corresponding circular cutter head; the installation positions of the cutting blades on the left and right circular cutter heads at the lower ends of the left rotating shaft and the right rotating shaft of the root cutter form an included angle of 45 degrees. The root cutter is simple in structure and convenient to install and use; soil on sugarcanes can be leaked via the four hollow-out sector grooves in each circular cutter head, so that the quantity of carried sugarcane soil in cutting can be reduced and the sugar quality can be improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery manufacturing, and relates to a sugarcane harvester, in particular to a sugarcane harvester root cutter with the function of leaking soil Background technique [0002] With the in-depth promotion of domestic agricultural mechanization, the technology of sugarcane harvesters is becoming more and more mature. The first step of the sugarcane harvester is to cut off the mature sugarcane in the field, and then carry out subsequent operations. A good sugarcane cutting device can not only improve the efficiency of mechanized operations, but also improve the quality of operations and reduce costs. There are mainly two kinds of mature sugarcane cutting devices in the market. One is a disc cutter, which is mainly composed of a blade and a disc. The blade is a rectangular blade fixed on the periphery of the disc. The blade rotates and cuts with the disc under the rotation force. The cutter d...

Problems solved by technology

However, since the cutterheads of the root cutters of the existing sugarcane harvesters are all solid disc structures, some soil will be brought into the harvester due to the friction on the surface of the cutterheads during the high-speed rotation of the left and right cutterheads to cut sugarcane. In the conveying channel, a certain amount of soil is added to the raw cane. After the raw cane mixed with soil enters the sugar factory, it will have a great impact on the production process and sugar quality of the sugar factory.
