Multifunctional trail-type potato combine harvester

Abstract

Disclosed is a multifunctional trail-type potato combine harvester. The multifunctional trail-type potato combine harvester is characterized by comprising a harvesting machine frame [1], a digging shovel [4], a lifting conveyer belt [7], a separation machine frame [59], a stretchy connector [36], a vertical elevator [37], a three-item plug board sliding channel bucket [38], a sub machine box [46], an externally-hanging folding conveyer belt [39], a potato collection box [31], a diesel engine [23], a gear pump [24], a distributor [18], a hydraulic motor [33] and the like. The multifunctional trail-type potato combine harvester is used for harvesting potatoes, and meanwhile most stone impurities on the surface layer of farmland can be picked out; manual work is saved, mechanical operation is achieved, and the working efficiency is high; the function is complete. By means of the multifunctional trail-type potato combine harvester, the functions of digging, impurity separating, impurity collecting, potato classifying, bagging, side-output truck loading joint operation, placing and stacking and the like can be achieved at one time, and thus one harvester can achieve multiple purposes. When being not used for harvesting potatoes, the multifunctional trail-type potato combine harvester can be used for conducting the soil sanitation operation alone before spring sowing and after autumn harvest. Independent power output can be achieved. After entering the harvester, the potatoes can not make contact with a chain, and therefore the defects that the length of the chain is increased so that soil leakage can happen and the chain is forcibly vibrated by an eccentric gear so that potato skin can be damaged are overcome.

Description

technical field [0001] The invention belongs to an agricultural machine, which is a mechanical device suitable for harvesting in potato planting areas, and can also be used alone for cleaning stones and other impurities in the soil. technical background [0002] At present, the potato harvesting operation in my country is still dominated by manual picking. The low-level mechanized state of turning potatoes onto the ground with machinery or manual digging requires a lot of manual work for picking, sorting, bagging, loading, and manual harvesting. The labor intensity of farmers is very high for picking up piles and other processes. In recent years, with the sharp decline of the rural labor force, labor can no longer meet the huge demand for potato harvest.

Problems solved by technology

[0002] At present, the potato harvesting operation in my country is still dominated by manual picking. The low-level mechanized state of turning potatoes onto the ground with machinery or manual digging requires a lot of manual work for picking, sorting, bagging, loading, and manual harvesting. The labor intensity of farmers is very high in picking up piles and other processes

In recent years, with the sharp decline of the rural labor force, labor can no longer meet the huge demand for potato harvests

In the face of rising labor costs year by year, resulting in a significant decline in the income of potato growers, there is an urgent need for a medium-to-large multi-functional harvesting machine that can meet the different requirements for potato harvesting in different regions of the country.

At present, most of the potato harvesters produced in China have single functions and are mostly miniaturized. They can only do the function of turning potatoes from the ground to the ground, which cannot reduce labor costs and labor intensity. Some manufacturers also imitate foreign countries. Based on the principle of large-scale potato harvesting machinery, some medium-sized products have been developed. However, when these machines face hillsides and areas with high soil viscosity, especially in areas with many rocks in the soil, these difficulties in mechanical technology have not been solved, which directly led to these problems. Machinery has been stuck in the experimental stage and cannot be promoted

However, foreign potato harvesting machinery has huge volume, high cost, complicated technology, excessive traction load, and high requirements for terrain and soil impurities. At present, it does not meet the production needs of potato harvesting in my country.
