Bagging potato combined harvester

Abstract

The invention relates to the field of agricultural machinery and particularly relates to a bagging potato combined harvester. The combined harvester comprises a rack, a digging shovel, a stalk separation unit and a potato tuber lifting delivery unit. The combined harvester is characterized in that a traction unit is arranged at the front end of the rack, and the whole harvester is connected with a pull rod through the traction unit. A hydraulic lifting oil cylinder is arranged on the upper portion of the rack and is hinged to the upper portion of the digging shovel. A transmission is arranged above the rack and is connected with a transmission shaft. A stopping support wheel, a soil and potato separation delivery unit, the potato tuber lifting delivery unit and a traveling unit are arranged below the rack successively. A bagging unit and a standing platform are arranged behind the rack. By means of the combined harvester, processes of tuber crop digging, stalk and mulch separation, potato tuber collection bagging and the like can be completed through one step, the work efficiency and the labor productivity of potato harvesting are improved greatly, and the labor intensity of human is further reduced.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a bagged potato combine harvester. Background technique [0002] At present, the potato harvesting machines put into use in China are mainly small and medium-sized potato excavators, which still need to be manually picked up and loaded into trucks or bags, resulting in low production efficiency and high labor intensity. There are some combine harvesters with grading and bagging functions, but these machines have large supporting power, high price, and there are problems of high potato damage rate and high skin breakage rate. Large-scale potato combine harvesters in foreign countries are divided into self-storage type and side wall output type, and the side arm output type is widely used, which is bulky and requires a large supporting power. Field work. At present, the combined harvester that is suitable for medium-sized plots and can realize potato digging and bagging is o...

AI Technical Summary

Problems solved by technology

At present, the combined harvester that is suitable for medium-sized plots and can realize potato digging and bagging is only seen in the invention patent ZL201320188740.3 authorized by me. It is opposite to the forward direction of the tractor, and the working position does not meet the requirements of ergonomics. At the same time, it is inconvenient to load and unload, and there are certain safety hazards. Therefore, safer and more efficient similar tools are needed to realize the corresponding functions.
