Understanding of the types of sugarcane harvesting machinery
The whole mechanization of sugarcane production includes ploughing, planting, cultivating, planting, harvesting, and shipping. The harvesting includes cutting, cutting, cleaning and shipping operations. The workload is the most and the most difficult, accounting for the total production of sugar cane. 55% of the workload. The proportion of time in each process was: harvesting accounted for 17.0%, peeling leaves accounted for 59.3%, clean-up bales accounted for 10.9%, and shipments accounted for 12.8%. The mechanical harvesting of sugar cane is divided into two types: harvesting and combined harvesting. The sectional harvesting machinery includes sugarcane cutting machine, sugar cane stripping machine, sugar cane loader, etc., most of which belong to the whole rod harvesting machine; The sugarcane combine harvester includes two types of full-rod combine harvester and cut-type combine harvester. Models and main performance parameters of sugarcane harvesting machinery developed at home and abroad. Sugar cane cutting machine Most of the sugarcane cutters are self-propelled small cutting machines or small and medium-sized wheeled tractors, which are more convenient to transfer in sugarcane field. The supporting power is mostly 4 kW~25 kW, generally consisting of disc cutters and belt fingers. The chain cane and the placement device are composed. During the operation, the cane holder lifts the fallen sugarcane plant, and the cane root is cut by a disc cutter and placed on the ground through the laying device. Its structural features: general installation of ground profile mechanism, the height of the header can be adjusted. Representative models such as the NB-11K model produced by Japan's Kubota Company, and the front-mounted sugarcane cutters developed by the China Agricultural Machinery Research Institute. Sugar cane stripping machine Most of them are small self-propelled leaf-leafing machines or walking tractors as supporting powers to facilitate the movement of sugarcane fields and to accommodate horizontal stacking of sugarcane stripping operations. The service life of the stripping element and the stripping effect are the key to the design of the stripping part and the difficulty in the design of the sugarcane harvesting machine. In the past, the stripping machine developed at home and abroad used rubber stripping parts. Because rubber parts are easy to wear, the lifespan is short, and the adaptability of curved and uneven sugarcane plants is poor and cannot be applied in a large area. In recent years, the stripping machine developed by the company has improved the overall performance by using a stripping member such as a nylon filament and a stripping assembly. The 4ZB-6A sugar cane stripping machine developed by Guangxi University adopts the upper and lower stripping assembly structure, and its main technical indicators have reached the level of similar foreign models. Sugar cane loader There are three types of sugar cane loaders: one is a hopper loader, a special hopper that can be lifted and lowered on the tractor, and goes along with the sugar cane stripping machine to take the sugar cane section after the cutting mechanism is cut off. Discharge into the bag on the ground. The second is the grab-type loader, which is equipped with a lifting mechanism, which can be used to grab piles of sugar cane into the transport truck. The third is the lift loader, which adopts double-chain lifting structure, most of which is mobile, equipped with small diesel engine, which can be installed on the walking tractor for convenient transfer, and also fixed by motor. 5S-15 type walking tractor type sugar cane lifting loader developed by Nanning Agricultural Machinery Technology Promotion Station in Guangxi. Sugar cane combine harvester When cutting the harvest, it must arrive at the sugar mill for pressing within 24 hours, otherwise it will cause deterioration of the raw materials and loss of sugar content. The process mainly includes sugarcane, sugarcane, cutting, cutting cane root, transporting sugarcane plant, removing impurities, cutting segments, transporting sugarcane segments and screening sediment, wind-selecting and removing impurities, and loading sugarcane segments. During the operation, the cutting-edge disc cutter cuts the cane tip and throws it to the cut ground. The spiral cane on both sides of the header pushes the sugarcane plant into the header. The sugarcane plant is tilted forward by the frame, the root is cut by the bottom disc knife, and the sugarcane plant is sent to the cutting device through the lifting roller and the upper and lower conveying rollers. The sugarcane segment cut into 25-40 mm passes through 2 axial flows. The fan absorbs light debris, and the heavier debris is in the elevator. The bottom of the bottom plate is discharged from the machine, and the cane section is thrown into the parallel traveling cart by the elevator. The power supply is 147 ~ 245 kW, and the production efficiency is up to 50 tons / hour. The representative model is the Case-7000 type segmented sugarcane combine harvester and the cutting section sugarcane combine harvester of Guangxi Agricultural Machinery Research Institute. When the whole rod type is harvested, the sugar cane has less breakage, can be stored for a long time, and has less loss, and the harvesting and shipping can be carried out separately, but the harvested sugar cane is not easy to be shipped due to low utilization rate of the carriage, and the sugarcane adaptability is more serious. difference. The whole process of the sugarcane combine harvester is generally divided into sugarcane, cane, cut tip, cane root, stripping, and heap. During the operation, the tip of the rod is introduced into the cutting disc knife, and the cut sugarcane tip is thrown by the tipping wheel to the cut ground. The sugarcane plant is pushed forward by the push rod, and the root of the sugar cane is cut by the double disc cutter. And fall on the cutting blade. Under the joint action of the cutting blade surface, the feeding dial and the lifting roller, the stripping device is fed to perform the stripping operation, the leaves are cleared out of the machine, and the sugar cane is sent into the loading vehicle behind the machine. The representative model is the KALTOR-80 model developed by Guangxi Agricultural Machinery Research Institute.
