Description

Technical field:

[0001] The invention relates to the technical field of mixed-seed cyperus chinensis, in particular to a mixed-seed cyperus chinensis harvester. Background technology:

[0002] Cyperus oleifera is a crop rich in nutrients such as starch, oil, sugar, protein and minerals. It is widely planted in Xinjiang Uygur Autonomous Region because of its drought resistance, waterlogging resistance and barrenness resistance. Cyperus oleifera mainly has two varieties, long beans and round beans. If only one variety is planted, the yield per mu is about 1,000 catties. In order to increase the yield, mixed planting is currently widely used, that is, planting round beans at 7-8 cm underground and planting long beans at 3-4 cm underground. The yield per mu can be increased by 500-600 catties, increasing farmers' income. Although the cyperus rotundus harvester disclosed in patent CN201821717260.0 can realize the classification of round beans and long beans, there are the following problems in actual use: 1. The density of the mixed plants of round beans and long beans is large, and the plants dug up by the rotary tillage harrow are accompanied by a large number of cyperus rotundus and soil clods, which will directly fill the internal space of the inner screen cage when transported to the inner screen cage by the net belt conveyor; in the process of the spiral blade pushing the plant backward, the mixture of the plant, cyperus rotundus and soil clods has a small activity space in the inner screen cage, resulting in a large number of cyperus rotundus entrained in the plants discharged from the inner screen cage, affecting the yield of cyperus rotundus; 2. There are many plants, cyperus rotundus and clods of soil at the inlet end of the inner screen cage. When the spiral blades push the plants backward, most of the cyperus rotundus and clods of soil enter the middle screen cage through the second half of the inner screen cage, resulting in a short screening stroke of the cyperus rotundus and clods of soil in the middle screen cage, incomplete screening, and a large number of long beans and clods of soil mixed with the round beans discharged from the middle outlet, with a high impurity content. The price of round beans is lower than that of long beans. Long beans are mixed with round beans and sold at the price of round beans, which directly affects the overall income. 3. The long beans and clods screened by the middle screen cage are also mainly concentrated in the second half of the outer screen cage, and there are also problems of poor screening effect and high impurity content.
