Description

Technical Field

[0001] The utility model relates to the technical field of sugarcane harvesters, and particularly discloses a sugarcane floating roller structure driven by a motor. Background Art

[0002] In the segmented sugarcane harvester, there are usually two layers of conveying rollers in front of the sugarcane segmenting device, which are used to clamp the sugarcane and convey it to the segmenting device. Due to the uneven amount of sugarcane in the early cutting and feeding process, in order to avoid damage to the sugarcane caused by excessive squeezing when the amount of sugarcane passing is relatively large, the upper rollers generally adopt a floating structure, which can automatically adjust the distance between the upper and lower rows of rollers according to the amount of sugarcane.

[0003] The original floating roller structure is mainly used in sugarcane combine harvesters. This is an integrated operation mode of cutting, conveying, cutting, removing impurities and loading sugarcane directly in the sugarcane field. However, in recent years, distributed sugarcane harvesters have also begun to be used in large quantities, but the floating roller structures on these machines are directly inherited from sugarcane combine harvesters and are often driven by hydraulic motors. This is inconsistent with the fact that distributed sugarcane harvesting equipment is mostly driven by motors. Many distributed sugarcane harvesters often need to be equipped with dedicated motor-driven hydraulic stations to realize the supply of hydraulic oil. This makes it impossible to fully obtain the energy-saving and cost advantages brought by motor drive, and also causes difficulties in daily use and maintenance.

[0004] However, if the motor is directly connected to drive the roller, the floating effect cannot be achieved because the motor of the same power level is much larger in size and weight than the hydraulic motor. If the V-belt or chain drive is used, the length of the drive link will change greatly during the floating process of the floating roller. Therefore, it is difficult for the ordinary structure to achieve the effect of the motor driving the floating roller at the same time. Often, the upper roller can only be turned into a fixed structure, thus losing the floating function, which is easy to cause damage to the sugarcane, reduce efficiency and increase waste.
