Potato harvesting machine for hilly and mountains regions

Abstract

The invention relates to a potato harvesting machine for hilly and mountains regions, and belongs to the field of agricultural harvesting machinery and equipment. An excavating device digs up soil andpotato mixtures; power is transmitted to a power transmission system through a power output shaft of a tractor, is outputted to drive shafts in a gear box to rotate, and is transmitted to a driving wheel through a chain to drive vibration separating devices to rotate; the primary vibration separating device is rotated to vibrate and separate the soil and potato mixtures which are then conveyed tothe secondary vibration separating device; potatoes with less soil are subjected to vibration separating again by the secondary vibration separating device, and then conveyed to a lateral conveying system. The potato harvesting machine has the advantages that the angle of the excavating device is adjusted through a hydraulic cylinder to achieve stepless angle adjustment; the two-stage vibration separating devices are applied to solve the problem of high soil stickiness of the hilly and mountains regions, and the separation frequency is high; the potatoes are piled up in strips through a lateral conveying device, the rate of visible potatoes is increased, and the potato burry rate and damage rate are decreased.

Description

technical field [0001] The invention relates to a hilly and mountainous potato harvester, which belongs to the technical field of agricultural harvesting machinery and equipment. Background technique [0002] The potato is the fourth largest food crop in the world, and it is also an economic crop. It is of great significance in solving the world's food shortage problem, ensuring energy security, improving food nutrition and achieving the Millennium Development Goals. Therefore, the United Nations named it in 2008 "International Year of the Potato". At present, the development of potato industry in developed countries and developing countries is uneven. The potato industry in developed countries is relatively mature, relying on technological innovation, long industrial chain, large-scale development, and mechanized production. However, the technological level of potato industry in developing countries is not high, the production scale is small and scattered, the variety is ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: the present invention provides a potato harvester for hills and mountains, which is driven by a tractor, adjusts the angle of the digging shovel through a hydraulic cylinder, and puts the potatoes in strips in the field by a lateral output device, so as to solve the current problem of hills and mountains. In mountainous areas, the separation efficiency of potato and soil is low, the rate of damaged potato is high, and the rate of clear potato is low.
