Description

Technical Field

[0001] The invention relates to a sugarcane harvesting device, in particular to a sugarcane stacker which can harvest sugarcane and automatically stack and gather the cut sugarcane, and belongs to the technical field of agricultural machinery and equipment. Background Art

[0002] Existing sugarcane harvesters are mainly divided into two categories: segmented and whole-stem. The segmented harvester has a large body and cuts the sugarcane into segments during harvesting, resulting in large sugar loss and high impurity content, which is not conducive to the preservation of raw sugarcane and is not suitable for my country's current sugarcane planting situation and the production process of sugar-making enterprises. Therefore, the whole-stem sugarcane harvester with a relatively small body is more acceptable on the market. There are many types of whole-stem sugarcane harvesters. The most widely used model is the sugarcane cutter and pavers, which work by cutting from the root of the sugarcane, and all the cut sugarcanes are tilted to one side and spread horizontally on the sugarcane ridges. The sugarcane harvesting machine has a fast harvesting speed, but it lacks the function of collecting and gathering. The cut sugarcanes are scattered on the sugarcane ridges in a disorderly and staggered manner. After the harvesting is completed, the cut sugarcanes must be manually collected and gathered and loaded onto a truck and transported to the defoliator for defoliation. This is inefficient, and when the transport truck enters the sugarcane field to load the sugarcane, it is easy to crush the sugarcane stumps in the sugarcane field, resulting in a low sugarcane emergence rate and reduced production in the next year.

[0003] In order to solve this problem, we have developed a sugarcane stacker, which works in the following way: the sugarcane supporting and gathering mechanism and the knife disc mechanism at the front end straighten and gather the sugarcane to be harvested, and then cut it off from the root. The sugarcane feeding mechanism then throws the cut sugarcane into the sugarcane collecting box at the rear end for automatic stacking and gathering. When the sugarcane stacker harvests to the field, it unloads the sugarcane in the sugarcane collecting box at the field end, and the transfer vehicle can load the harvested sugarcane at the field end and transfer it to the defoliator for defoliation. This can not only improve the efficiency of sugarcane collection and transportation, but also prevent the transfer vehicle from driving into the sugarcane field and crushing the sugarcane stumps.

Therefore, compared with the sugarcane harvester, the sugarcane harvester can not only harvest sugarcane but also automatically stack and gather the cut sugarcane. When the sugarcane harvester reaches the end of the field, the sugarcane in the sugarcane collecting box can be unloaded at the end of the field, and the transfer vehicle loads the harvested sugarcane at the end of the field and transfers it to the defoliator for defoliation. This can not only improve the efficiency of sugarcane collection and transportation, but also prevent the transfer vehicle from driving into the sugarcane field to crush the sugarcane stumps and affect the emergence rate of sugarcane next year. In addition, the structure design of the sugarcane feeding mechanism of the sugarcane harvester is ingenious, and the shape of its deformable entrainment can be adaptively adjusted according to the feeding situation of the sugarcane. Whether it is a single sugarcane or multiple sugarcanes gathered in a pile, stable clamping and transportation can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS
