A channel device hydraulic control system for sugarcane harvester

Abstract

The invention relates to a passage device hydraulic control system of a cane harvester. The passage device hydraulic control system of the cane harvester comprises a closed type hydraulic pump, a leaf stripping hydraulic motor, a leaf division hydraulic motor, an output hydraulic motor, a washing valve and a throttling valve, wherein the closed type hydraulic pump is connected to a push rod handle of an operation room through a flexible shaft coupler, the closed type hydraulic pump, the leaf stripping hydraulic motor, the leaf division hydraulic motor and the output hydraulic motor are sequentially connected in series to form a closed loop, the washing valve is connected in the closed loop in parallel, and the leaf division hydraulic motor and the output hydraulic motor are respectively connected with the throttling valve in parallel. The hydraulic control system is suitable for passage work for cane harvesting, and can generate large carrying capacity in the leaf stripping process. The serial-connection structure can effectively reduce pipeline connection and spatial layout compared with an independently controlled parallel-connection structure, the leaf stripping motor can increase output torsion to prevent canes from being blocked in a passage, different speeds of the motors can be adjusted through the throttling valve, and passage work is coordinated.

Description

technical field [0001] The invention relates to the technical field of sugarcane harvesting machinery, in particular to a hydraulic control system for a channel device of a sugarcane harvester. Background technique [0002] The harvesting of sugarcane requires that the outer cane leaves should be peeled off during the harvesting process. At the same time, in order not to lose the sugar and damage the skin of the sugarcane, sugarcane harvesting has long been a tedious manual labor with a large amount of labor, low efficiency and high cost. During the mechanical harvesting of sugarcane, the sugarcane harvesting and cutting of cane tips are first carried out through the bottom cutter head and the top cutter head, and then it is sent to the harvester to strip leaves, and then transported to the collection vehicle. The most important thing in the whole harvesting process is the leaf stripping and conveying process in the channel. This work first requires the conveying force and s...
