Sugarcane leaf grinding device

Abstract

The invention relates to a sugarcane leaf grinding device. The device comprises at least one pair of leaf grinding wheels which are correspondingly arranged above and below a sugarcane conveying channel, wherein each leaf grinding wheel comprises a center shaft for installation and a roller which rotates by taking the center shaft as the axis; the outer peripheral surface of each roller is provided with a plurality of steel wires which are distributed in a matrix shape; and the steel wires extend along the radial directions of the rollers. The leaf grinding device can be used for ripping and grinding sugarcane leaves outside sugarcanes; after being processed by a leaf stripping brush device, the sugarcane leaves can be stripped cleanly; the bottom parts of the steel wires on the leaf grinding wheels are provided with helical springs, so that the steel wires can swing up and down and left and right, sugarcane skin is prevented from being scratched, the blockage of the sugarcane leaves is prevented and the leaf grinding effect and the leaf stripping effect of a combine harvester are further ensured.

Description

technical field [0001] The invention relates to a leaf crushing device, in particular to a sugarcane leaf crushing device used in a sugarcane combine harvester. Background technique [0002] In the past, most of the sugarcane harvesting in my country was done manually, but relying on manual labor is not only time-consuming, labor-intensive, and labor-inefficient, but also the cost of sugarcane harvesting is relatively high, so some mechanization has emerged means of harvesting. [0003] Some basic requirements for sugarcane harvesting include: 1. Cut off the sugarcane, the cut stubble is required to be 2-3cm above the ground, and there should be no damage to the cracks, otherwise it will affect the harvest of the sugarcane in the next few years. 2. Remove the tail For tender stems, it is required to remove the tail from the soft tissue of the sugarcane. If the tail is cut too little, the sugar content in the left sugarcane tail will be low, which will affect the sugar yield ...

Problems solved by technology

Whole-rod sugarcane harvesters, such as the "Multifunctional Sugarcane Combine Harvester" disclosed in Chinese Patent No. ZL200420064926.9, the "Sugarcane Combine Harvester" disclosed in Chinese Patent No. ZL200520200252.5, and the patent No. ZL200520200253.x The disclosed patents such as "sugarcane combine harvester" usually include power system, walking system, operating system, front tail cutting mechanism, front gathering mechanism, chopping mechanism and leaf stripping mechanism, and the leaf stripping mechanism of these patents also has deficiencies. These leaf stripping mechanisms are basically arranged in pairs of stripping rollers that appear up and down on the sugarcane transmission channel. The stripping rollers are usually composed of roller shafts and elastic ribs arranged on the roller shafts, and most of them In these sugarcane harvesters, the forward transmission of sugarcane in the whole stripping section is only completed by the stripping rollers, even if the individual sugarcane harvesters are provided with additional conveying rollers or inert damping rollers, which are structurally There are also deficiencies in the setting and location, and it is difficult to achieve the desired effect

The leaf stripping roller has strong deformation ability due to the elastic ribs on it, and the completion of leaf stripping must depend on the difference between the transmission speed and the linear velocity of the elastic ribs of the leaf stripping roller, and the individual size of sugarcane varies greatly , so only relying on the stripping roller to complete the forward transmission of sugarcane, there will be a defect that the transmission speed is not stable, which will affect the effect of stripping leaves, and even cause serious blockage of sugarcane in the transmission channel

[0005] Therefore there are always various defects in the combine harvester in the prior art, and only having the stripping device can not guarantee that the sugarcane leaf of sugarcane is stripped clean
