Technical Field

The invention relates to the technical field of manufacturing of sugarcane harvesters, in particular to a device for separating sugarcane leaf and stem.

Background

The whole cane has a lot of leaves from the beginning to a little bit, and leaves of the cane must be stripped off after the cane is harvested and before the cane is sent to a sugar mill for sugar extraction. At present, domestic sugarcane farmers most often adopt manual leaf stripping, because the cleanliness of manual leaf stripping is high, the impurity content of the sugarcane is low, the condition that sugarcane impurity content required by a sugar refinery is lower than 2% can be basically met, but the workload of sugarcane leaf stripping accounts for about 65% of the workload of whole sugarcane harvesting, the labor amount of manual leaf stripping is very large, the leaf stripping efficiency is low, the labor cost is high, and the wide planting of the sugarcane is greatly restricted. The mechanical leaf peeling equipment can greatly improve the leaf peeling efficiency, but after the sugarcane enters the leaf peeling equipment, the sugarcane leaves can be wound on the sugarcane stalks under the influence of the limitation of adjacent sugarcane and conveying channels inside the leaf peeling equipment, and the peeling and the separation are very difficult. The impurity content of the sugarcane peeled by the early sugarcane leaf peeling equipment even exceeds 20 percent, and the sugarcane can not be applied to actual operation because a sugar factory can reject the sugarcane with the impurity content higher than 7 percent. With the continuous promotion of the mechanized development process of sugarcane harvesting, the sugarcane leaf stripping rate of various sugarcane leaf stripping devices is greatly improved. The key mechanism of the leaf and stem separation of the existing sugarcane leaf peeling equipment is two leaf peeling rollers which have the same structure and are arranged up and down, the leaf peeling rollers mainly comprise rotating shafts and leaf peeling elements arranged on the rotating shafts, the working principle of the sugarcane leaf peeling equipment is that the leaf peeling elements are driven by the centrifugal force generated by the rotation of the rotating shafts, sugarcane leaves on the sugarcane stems moving in a leaf peeling channel are impacted and rubbed for many times, and therefore the sugarcane leaves on the sugarcane stems can be peeled efficiently. The leaf peeling element is a core element of the longitudinal and transverse leaf rod separating device, the working quality of the leaf peeling element directly influences the efficiency and quality of sugarcane leaf peeling, common leaf peeling elements comprise a hobbing cutter, a leaf peeling plate, a steel wire brush, a nylon brush, a rubber finger and the like, the leaf peeling elements can be classified into rigid leaf peeling elements and elastic leaf peeling elements, the rigid leaf peeling elements can impact and rub sugarcane leaves greatly, and the sugarcane rods are damaged, even split or broken; in the process of beating the sugarcane leaves by the elastic material leaf stripping element, the damage degree of the sugarcane stalks is low due to the fact that the material of the element is soft, but the leaf stripping element is easy to wear and needs to be replaced integrally, and material waste is serious. No matter which type of leaf peeling element is used, after the sugarcane leaves are peeled off from the sugarcane stalks, the fallen leaves below and on the side surfaces of the sugarcane stalks can fall on the ground under the impact and gravity action of the leaf peeling element, so that the fallen leaves are discharged out of the sugarcane leaf peeling equipment; however, the defoliation located above the sugarcane stalks or the defoliation partially sandwiched between the sugarcane stalks and the sugarcane conveying channel due to the limitation of the sugarcane conveying channel can enter the sugarcane collecting container together with the sugarcane stalks, so that the sugarcane leaves and the sugarcane stalks cannot be well separated, the cleanliness of the defoliation is low, and the impurity content is high. The problem can not be well solved in the industry all the time, the bottleneck of high impurity rate of the sugarcane leaf peeling equipment can not be broken through, and the problem is the main reason of the situation that less sugarcane harvesters of domestic sugar mills receive the sugarcanes. In addition, if the defoliation above the sugarcane stalks is excessive and the accumulation is formed in the sugarcane leaf stripping conveying channel, the blockage phenomenon is easy to occur, the machine is stopped for maintenance frequently when needed, and the leaf stripping efficiency is reduced.

When the sugarcane with the sugarcane leaves peeled off is conveyed between the transverse sugarcane leaf discharging unit 30 and the reverse-beating sugarcane leaf discharging unit 40, the circularly rotating sugarcane leaf discharging belt 35 continuously scrapes and takes off the peeled sugarcane leaves between the sugarcane stalks and the working surface 35-1 of the sugarcane leaf discharging belt 35, so that the peeled sugarcane leaves are discharged from the side surface of the leaf peeling equipment; meanwhile, the lower reverse beating roller 41 rotates reversely relative to the conveying direction of the sugarcane, each reverse beating plate 42 continuously beats the suspended threshing leaves, and the suspended threshing leaves are beaten, scraped off or positioned in a lower threshing leaf collecting container under the action of beating force and saw teeth. After the sugarcane is subjected to all-directional leaf stripping by the leaf stripping unit 20, and the transverse leaf discharge of the transverse leaf discharge unit 30 and the longitudinal leaf discharge of the reverse beating leaf discharge unit 40, sugarcane stalks are completely separated from the sugarcane leaves, the sugarcane stalks enter the rear group of conveying units 60 through the guide of the limiting unit 50, and the sugarcane stalks are conveyed into the sugarcane collecting container through the conveying units 60.

After the leaves are peeled by the leaf peeling unit 20, the sugarcane leaves and the sugarcane stalks are thoroughly separated through the vertical and horizontal leaf arrangement by the reverse beating leaf arrangement unit 40 and the horizontal leaf arrangement unit 30, the leaves are peeled cleanly, the impurity content is effectively reduced, the long-time continuous and smooth operation of the leaf peeling equipment is ensured, and the service life is also prolonged.
