Combined sugarcane harvester

Abstract

The invention provides a combined sugarcane harvester, which relates to the technical field of agricultural machinery. The harvester comprises a gantry front axle device connected with the front end of a frame, two groups of separation mechanisms which are symmetrically arranged on the two sides in front of a front wheel of the sugarcane harvester, a header device which is located on the back side of the gantry front axle device and is connected with the lower side of a harvester cab, a channel device which is connected to the back end of the header device and is fixed on the frame, and an engine placed on the frame, wherein a channel of the channel device is enclosed by two channel side plates and is internally provided with a leaf stripping and tail cutting device, a speed limiting device and a reverse-rotation leaf discharging device; the engine is connected with a transfer case assembly; the power output end of the transfer case assembly is respectively connected with transmission shafts I and II; the transmission shaft I is used for transferring power to a roller driving shaft of the leaf stripping and tail cutting device through a tapered power-input gear box located outside the channel side plate; the roller driving shaft is used for transferring the power to the other devices in the channel through a channel transmission device; and the transmission shaft II is used for transferring the power to a rear axle assembly through a speed changing box.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a sugarcane harvesting mechanical device. Background technique [0002] At present, the sugarcane combine harvesters at home and abroad mainly include two categories: section type and whole bar type. The former cuts the whole sugarcane into small sections of equal length when harvesting sugarcane. The operation process of this type of harvesting method is relatively simple, so the technology of this type of sugarcane harvester is relatively mature and the harvesting efficiency is relatively high. However, because the sugarcane is cut into sections during harvesting, there are many cuts, which is not conducive to the preservation of the raw material sugarcane. During the preservation process, the deterioration of the sugarcane will easily cause large losses, and this type of machine body is too large to be suitable for small-scale operations, and the price is high. ...

Problems solved by technology

However, because the sugarcane is cut into sections during harvesting, there are many cuts, which is not conducive to the preservation of the raw material sugarcane. During the preservation process, the deterioration of the sugarcane will easily cause large losses, and this type of machine body is too large to be suitable for small-scale operations, and the price is high. , so it is not conducive to large-scale application in sugarcane planting areas in my country

The whole-bar sugarcane combine harvester is more suitable for my country's sugarcane production conditions and the production process of sugar enterprises, but its operation effect requirements are high, the process is relatively complicated, and the main core technology is difficult to break through

Existing whole bar type sugarcane combine harvester mainly has the deficiencies in the following aspects: 1. The separation of lodging sugarcane. When lifting the lodging sugarcane, the sugarcane will be broken due to the resistance of the sugarcane crossing and lodging, which is not conducive to harvesting. More importantly, after the cane root is cut, it needs to have an upward lifting angle to be fed into the leaf stripping device. The tail of the cane is pressed down, and the spiral The righting device is to lift the tail of the sugarcane, which has a negative effect, so that the sugarcane whose root has been cut off cannot be smoothly fed into the leaf stripping device, which will easily cause the accumulation of sugarcane to block; Generally, the harvesting method is to cut off the cane tail first and then cut off the cane root. Because the sugarcane grows at different heights, and the tail removal device of the harvester cannot adjust the cutting height of the cane tail with the growth height of the sugarcane, it is easy to cause Cut off the cane stem and waste or incomplete removal of cane tail and high impurity content; 3, cutting of cane root, the existing sugarcane combine harvester generally sets the cutting device of cane root at the front end of the harvester walking front wheel, In this way, the cutting device cannot be lifted and lowered in balance with the walking front wheels. When the working ground is uneven, the cutting knife is likely to hang in the air or be inserted into the soil, resulting in excessive loss and waste of the harvested cane roots or digging up the cane roots and affecting the perennial roots. Seedling emergence, this setting method also increases the length of the whole machine, making it difficult for the harvester to turn around, which is not conducive to the operation of small plots; The leaf device is a difficult problem for sugarcane combine harvesters. The existing sugarcane combine harvesters generally use a dial wheel on the cutting cutter head or use a chain to drive and clamp the paddle to complete the conveying and feeding of sugarcane. Finally, the whole sugarcane did not fall to the ground immediately. The function of the dial wheel is only to push the sugarcane down. It takes two or more times to feed the sugarcane. It is easy to cause the sugarcane to accumulate at the entrance and enter the stripping channel at the same time. The channel is blocked or even damaged the machine, and the chain method is used due to the harsh working conditions, the chain cannot be lubricated and protected, it is easy to wear and loose or be broken, and it cannot work normally; The rotation of the leaf stripping roller (leaf stripping wheel) in the leaf device scrapes the sugarcane through the stripping blades set on the stripping roller (striping wheel) to achieve the purpose of stripping sugarcane leaves. The stripping blades of the existing sugarcane combine harvester Generally used is a sawtooth or wavy rubber plate on the outside. If the rubber plate is too thick and too hard, it is easy to scrape off the sugarcane and cannot be collected, resulting in waste; The impurity content is too high, and more importantly, automatic tail docking cannot be completed in this form; 6. The separation of cane leaves. In this form, because the cane stem and the stripped cane leaves are squeezed together in the leaf stripping device, the cane leaves cannot be completely separated by wind force, and at the same time, the energy consumption and the manufacturing cost of the whole machine are increased due to the need to set a high-power fan
