Flexible clamping conveying impurity-removing device of combined harvester of Allium fistulosum L.var. giganteum Makion and application method of flexible clamping conveying impurity-removing device

Abstract

The invention relates to a flexible clamping conveying impurity-removing device of a combined harvester of Allium fistulosum L.var. giganteum Makion and an application method of the flexible clampingconveying impurity-removing device. The flexible clamping conveying impurity-removing device comprises a left clamping rack and a right clamping rack which are arranged side by side, wherein flexibleclamping conveyor belts are separately installed on the left clamping rack and the right clamping rack, support feeding devices are fixedly connected to input ends of the left clamping rack and the right clamping rack, and a tensioning device is arranged at the inner side of the flexible clamping conveyor belt on the right clamping rack. The flexible clamping conveying impurity-removing device canadapt to harvest of Allium fistulosum L.var. giganteum Makion of different growth conditions through arrangement of the support feeding devices, so that it is ensured that Allium fistulosum L.var. giganteum Makion is smoothly sent between the two flexible clamping conveyor belts, and the versatility of the harvester of Allium fistulosum L.var. giganteum Makion is improved; through arrangement ofthe flexible clamping conveyor belts, flexible clamping and conveying of Allium fistulosum L.var. giganteum Makion can be ahcieved, damage to Allium fistulosum L.var. giganteum Makion is reduced, andthe harvest quality is ensured; and through arrangement of the tensioning device, the spacing of the two flexible clamping conveyor belts can be adjusted so as to adapt to change of the diameter of Allium fistulosum L.var. giganteum Makion stems, and the reliable and continuity of clamping transportation are ensured.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a flexible clamping and conveying impurity cleaning device for a scallion combine harvester and a use method thereof. Background technique [0002] Green onions are one of the main characteristic economic crops in my country, with a long history of planting. The planting area of ​​green onions in my country is about 500,000 hectares every year, and the annual export volume accounts for 70% of the world, which has played an important role in promoting the local economy. [0003] Due to the large market demand and the strong environmental adaptability of scallions, they are planted all over the country, especially in Shandong, Henan, Hebei and other regions. Although the planting area of ​​scallions in our country is wide, the degree of mechanized harvesting is low, the damage rate of scallions is high during clamping and transportation, and the harvest quality is poor, which ...

AI Technical Summary

Problems solved by technology

Although the planting area of ​​scallions in our country is large, the degree of mechanized harvesting is low, the damage rate of scallions is high during clamping and transportation, and the harvest quality is poor, which seriously affects the development of scallions industry.

[0004] The patent with the application number 201520430190.0 discloses a conveying mechanism for a green onion harvester, but it cannot be applied to the harvest of green onions of different specifications, and its adaptability and versatility are poor
