Description
Technical Field
The invention relates to the field of agricultural machinery, in particular to a garlic combined harvesting and root cutting device.
Background
Garlic is an important economic crop and a very competitive export-induced product in China. The planting area, the yield and the export quantity of garlic all year round are the first in the world in China. In recent years, because the cost for manually harvesting garlic is increased and the labor intensity is high, the production cost of garlic is high, and farmers have urgent needs for mechanical garlic harvesting equipment. At present, no garlic combined harvesting equipment is available in domestic markets, and a few garlic combined harvesting sample machines are still in the research and development stage, so that the main reason is that the mechanical root cutting technical problem is not solved. The mechanical root cutting is a main difficult problem that garlic combined harvesting equipment needs to be cracked urgently and is also an operation link with the greatest technical difficulty. Looking up relevant data at home and abroad, no garlic harvest product capable of realizing mechanized root cutting operation exists.
The prior patents CN201410335115.6/CN201410335084.4/CN201410335126.4 and the like all adopt rolling type cutting (namely, a cutting knife rotates around a rotating shaft, and a cutting edge is parallel to the rotating shaft or slightly has a certain inclination angle), so that the actual application effect is poor, and the cutting knife is difficult to be applied to actual production. The problems are as follows: firstly, the root cutting device can obtain the shortest root cutting effect only when the lower spherical surface of the garlic is positioned at the highest point of the rotary surface of the cutter, and in addition, because each root can only pass through the highest point once, the cutting times are few, and the phenomenon of missed cutting exists. Secondly, in order to achieve the sliding cutting effect, the cutting edge of the root cutting device is usually designed with a certain angle with the rotating shaft, which results in that the distance between the middle part of the cutting edge and the rotating shaft line is the closest, namely the cutting point at the middle part of the cutting edge is the farthest from the garlic bulb, so that the root hair remained at the position is longer than that remained at other parts after cutting, and the shortest cutting effect cannot be obtained. Thirdly, the cutting is carried out without support (namely, one end of the root grows on the garlic, and the other end is in a free state without support), the root system can float, and the acting force of the cutter on the root system is reduced.
