Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a cutting table device installed on the rear end of a sugarcane harvester, which can cut and feed sugarcane with different thickness, length, length and straightness through the cutting table device, then lift and peel the sugarcane Tail trimming, sugarcane leaf separation and conveying device. Background technique [0002] Generally adopt the transmission mode that hydraulic pressure and chain combine in the channel device transmission mode of existing whole bar type sugarcane harvester, or all chain transmissions. Due to the harsh working environment of the harvester, these two transmission methods are not suitable. The hydraulic oil used to drive the motor is prone to failure due to the dirty environment, and the chain is easy to wear, loosen or even break due to the lack of lubrication due to the large dust , resulting in failure to work normally and affecting...

AI Technical Summary

Problems solved by technology

Due to the harsh working environment of the harvester, these two transmission methods are not suitable. The hydraulic oil used to drive the motor is prone to failure due to the dirty environment, and the chain is easy to wear, loosen or even break due to the lack of lubrication due to the large dust , resulting in failure to work normally and affecting harvesting operations

[0003] Existing full-rod sugarcane harvesters only have leaf stripping devices in the channel device, but no tail cutting device. Generally, an independent tail breaking device is installed above the front end of the harvester to complete the removal of sugarcane tails before the sugarcane is cut down. Sugarcane grows at different heights or lodging. This method of tail removal cannot automatically adjust the tail docking device to an appropriate height according to the height of sugarcane growth during harvesting. The phenomenon of tail trimming is too low or too high, resulting in loss of raw cane or excessive impurity content. In addition, this device requires additional power drives and auxiliary equipment, which increases the power consumption of the whole machine and increases the cost

[0004] Existing sugarcane harvesters generally adopt a high-power exhaust device above the channel. This device uses a high-power exhaust fan to extract the stripped sugarcane leaves in the way of suction, because the cane stems and sugarcane leaves in the channel device squeeze Pressing and mixing together, the exhaust fan cannot clean the sugarcane leaves, resulting in high impurity content in the sugarcane. In addition, this device increases the weight and volume of the whole machine, consumes power, and is costly. Therefore, this method of leaf discharge Not conducive to promoting the application

[0005] In the existing whole-rod sugarcane harvester channel device, there is no guiding device for sugarcane delivery, and the sugarcane is easily inserted into the gap between the side plate and the roller, which is likely to cause channel blockage and affect the normal operation of the harvester

[0006] The front half of the channel device of the existing full-rod sugarcane harvester is set under the driver's cab and runs through the whole machine. This installation is not convenient for the inspection and maintenance of the channel device
