Abstract
Description
Technical Field
[0001] The invention relates to the technical field of harvesters, and in particular to a high-altitude harvesting device. Background Art
[0002] Oil palm fruit, also known as palm fruit, has a fleshy outer layer with 45% to 50% oil content, a hard palm kernel inside, and a kernel inside the kernel; the flesh can be used to make skin oil, and the kernel can be used to make palm kernel oil. Oil palm fruit grows on oil palm trees, usually growing at the top of the tree in clusters, usually with about 10-15 fruit bunches per tree, and each bunch weighs between 15-25 kilograms.
[0003] Traditionally, when picking oil palm fruits, people rely on manual tree climbing for cutting and picking. However, oil palm fruits grow at a higher position. Therefore, not only is the picking efficiency low, but people under the tree are easily injured by falling fruits, and the picking process is very dangerous. With the continuous advancement of science and technology, some equipment that can automatically pick oil palm fruits has appeared on the market, such as a new type of oil palm fruit picking machine disclosed in the Chinese utility model patent with application number CN202322583552.7, which includes a base, a telescopic support arm, and a picking component and a collecting component arranged at the outer end of the telescopic support arm; an inclined pitching support arm is arranged between the base and the lower part of the telescopic support arm; the picking component includes two semicircular fixed knife seats and a telescopic knife head located on the axial upper end face of the fixed knife seat; the two fixed knife seats are hingedly connected by a rotating shaft, and the inner side of the fixed knife seat is provided with a nail buckle; the collecting component includes a collecting bin and a slideway tube respectively fixed to the outer cylindrical surface of the two fixed knife seats, and a material drop opening is arranged on the lower end face of the collecting bin and is connected to the slideway tube; a hydraulic system is also arranged. However, in the actual picking process, the outer side of the fruit bunch is usually blocked by the petiole and the leaf tray, so the following existing picking machines have the following defects in the actual picking process: 1. Since the outer side of the fruit bunch is blocked by the petiole and the leaf tray, the telescopic knife head on the upper end face of the fixed knife seat is difficult to effectively cut the fruit bunch of the oil palm fruit when it is extended upward; 2. The inner side surface of the fixed knife seat is provided with nail buckles, which are easy to damage the trunk in the process of clamping the trunk; 3. The adjustment function of the support arm is poor. Summary of the invention
