Description

Technical Field

[0001] This utility model relates to the technical field of sugarcane cleaning knife boxes, and in particular to a split-type knife box structure for sugarcane cleaning equipment. Background Technology

[0002] The manual harvesting method used for sugarcane is inefficient and costly, but the impurity content is around 7%. Compared to manual harvesting, harvesting with combine harvesters or other machinery is more efficient and cost-effective. Sugarcane harvesting is increasingly moving towards mechanization, intelligence, and automation. However, machine-harvested sugarcane has an impurity content as high as 10% to 20%. After machine harvesting, the sugarcane needs to be sent to sugarcane impurity removal equipment for impurity removal. The cutter box structure in the sugarcane impurity removal equipment is the cutting mechanism used to cut the sugarcane. In the existing cutter box structure, the cutting blades and the cutter shaft are installed as a whole. Once the cutting blades are damaged, the entire cutting shaft and blades need to be replaced and repaired. This is not only inconvenient to disassemble and assemble, but also has high maintenance costs, which cannot meet the needs of users in production. Utility Model Content

[0029] The installation process of the split-type blade box structure for the sugarcane impurity removal equipment of this utility model is as follows:

[0030] First, the installer can install the tool box 1 on the external frame. Then, the upper cutter roller assembly 2 and the lower cutter roller assembly 3 are installed inside the tool box 1. Since the upper cutter roller assembly 2 and the lower cutter roller assembly 3 are identical, the installation process of one of the two cutter roller assemblies will be described below. First, mounting holes adapted to the mounting shaft 21 are machined on the tool holder 24 and the spacer sleeve 25. The profile of the mounting holes is consistent with the outer periphery of the mounting shaft 21 (it can be a square profile). The tool holder 24 and the spacer sleeve 25 are installed on the mounting shaft 21 through the mounting holes. It is necessary to ensure that the tool holder 24 and the spacer sleeve 25 are spaced apart on the mounting shaft 21. The tool holder 24 consists of a cutter shaft mounting part 241 and a cutter body mounting part 242. The cutter shaft mounting part 241 is used to install and connect the cutter body mounting part 242. The three sets of cutter body mounting parts 242 are evenly distributed outside the cutter shaft mounting part 241 to ensure that each set of cutter bodies The mounting parts 242 are arranged at a 120-degree angle.
