Description

Technical Field

[0001] The invention relates to a sugarcane conveying mechanism, in particular to a sugarcane conveying mechanism in a sugarcane cutter and stacker for throwing sugarcane cut at the front end to a sugarcane collecting box at the rear end for stacking, 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 cutter and buncher. Its operation method is to cut the sugarcane from the root at the front end, and then throw the cut sugarcane into the sugarcane collection box at the rear end through the sugarcane feeding mechanism for automatic stacking. When the sugarcane cutter and buncher harvests to the field, it will unload the sugarcane in the sugarcane collection box at the field end. 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. In this sugarcane cutter and buncher, the sugarcane feeding mechanism is one of its core components. It can clamp the sugarcane cut from the root at the front end, then pull the sugarcane upward and backward and throw it into the sugarcane collection box at the rear end for automatic stacking. Summary of the invention

[0004] The object of the present invention is to provide a sugarcane delivery mechanism of a sugarcane harvester and buncher, which, as one of the core components of the sugarcane harvester and buncher, is used to pull the sugarcane cut at the front end upward and backward and throw it into a sugarcane collecting box at the rear end for automatic stacking and gathering.

[0011] The elastic telescopic frame is provided with a sliding telescopic sleeve, in which a pushing spring is arranged. The pushing spring automatically and elastically pushes the vertical wheel shaft connected to the front end of the telescopic sleeve, thereby realizing automatic tensioning of the deformable chain ring.
