Chinese yam harvester

Abstract

The invention relates to the field of agricultural machinery and in particular relates to a Chinese yam harvester. Manual excavating is generally adopted for avoiding damage to agricultural products and influence on quality when long tuber crops growing underground such as Chinese yam are harvested, labour intensity is high and working efficiency is low; and the existing harvester which is used for ditching and harvesting still requires more labour and is also lower in efficiency. The Chinese yam harvester provided by the invention comprises a rack, a Chinese yam taking mechanism, a soil returning board and a rack wheel and is simple in structure, practical and easy to manufacture, wherein the Chinese yam taking mechanism is composed of two rows of spiral groups, a disc shovel, a lifting shovel board and a separating board and has the functions of breaking soil, loosening the soil and lifting the soil. The Chinese yam lifting mechanism adopts two rows of devices composed of spiral groups and disc shovels for excavating and loosening the soil at the two sides and the bottom of a crop row ridge, then works together with the matched lifting shovel board and separating board to impact and shake the crop row ridge part to loosen the soil, and finally lifts the soil above ground, people can easily harvest Chinese yam, and product quality is guaranteed; and the soil returning board can scrape the broken soil into a row ditch, subsequent processes are reduced, and work efficiency is greatly improved.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to a yam harvesting machinery. Background technique [0002] Yam is a crop that has good nutrition and health effects and is loved by people. Because high-yield and high-quality yams usually grow 80-100cm deep under the soil, in order to avoid bruises and breaks when harvesting yams, which will affect product quality, the traditional way of harvesting yams requires deep digging of the soil and careful operation, which requires high-intensity physical strength , and the work efficiency is very low. Existing yam harvesting machines at present are more feasible only after a deep ditch is dug out on one side of the yam rhizome using a screw rod or a chain saw, and then the yam is carefully dug manually, and finally the ditch will be dug out. Filling deep trenches with soil is still time-consuming and labor-intensive, and the efficiency is low. In the published patent information, the patent ...

Problems solved by technology

[0003] The purpose of the present invention is to provide a structure and technical method for the manufacture of a yam harvester. The yam harvester is suitable for harvesting yams and similar crops that have specifications for planting and grow vertically under the soil to a depth of about 100 cm, so as to solve the problem of yam harvesting. The problem of high labor intensity and low efficiency of harvesting
