Problems solved by technology

[0003] The existing patents CN201410335115.6 / CN201410335084.4 / CN201410335126.4 are all rolling cutting (that is, the cutter rotates around the rotating shaft, and the blade is parallel to the rotating shaft or slightly inclined at a certain angle). The actual application effect is not good, and it is difficult to applied in actual production
The problem is as follows: First, this type of root cutting device can only achieve the shortest root cutting effect when the lower spherical surface of the garlic head is at the highest point of the rotary surface of the cutter. In addition, since each root system can only pass through the highest point once, the number of cuts Less, so there is a phenomenon of missed cut
Second, in order to achieve the sliding cutting effect of this type of root cutting device, the blade is usually designed with a certain angle to the rotary axis, which leads to "the distance between the middle of the cutting edge and the rotating axis is the closest", that is, the cutting point in the middle of the cutting edge is the farthest from the garlic head, making This place is longer than other parts after cutting, and the shortest cutting effect cannot be obtained
Third, they are all cut without support (that is, one end of the root grows on the head of garlic, and the other end is in a free state without support), the root system may flutter, which reduces the force of the cutter on the root system

Embodiment Construction

[0048] Attached below Figure 1-14 The present invention is further illustrated with specific examples.

[0049] Such as figure 1 , 2 As shown, a floating root cutting device for combined garlic harvesting includes a clamping chain 1 , an alignment chain 2 and a floating root cutting body part 3 .

[0050] Such as Figure 3-6 As shown, the above-mentioned floating root-cutting main body part 3 includes a fixed installation frame 12, and a protective net cover 10 with a circular cover structure that is inclined to the opposite direction of garlic conveying. The angle between the top surface of the protective net cover 10 and the conveying direction of the head of garlic is 10°, so as to prevent the garlic from directly impacting the protective net cover 10 during the transport process. The protective net cover 10 is provided with an inclination, which can ensure that when the head of garlic presses against the protective net cover 10, the protective net cover 10 can follow ...

Abstract

The invention relates to a floating root cutting device for garlic combined harvesting in the technical field of agricultural machinery. A floating root cutting main body component comprises a protective net cover which is obliquely arranged in the direction opposite to the garlic conveying direction; a plurality of floating springs are installed on an installation frame, and the floating springssupport and are connected to a connecting frame on the lower side of the protective net cover; a cutter head close to the top wall of the protective net cover and a cutter head base assembly for supporting and fixing the cutter head are arranged in the protective net cover, and a rotary driving component for driving the cutter head base assembly and the cutter head to rotate at a high speed is installed on the installation frame; the top wall of the protective net cover is arranged to be of a net-shaped structure densely provided with a plurality of top grid holes, and the center of the top ofthe protective net cover is arranged to be of a vertically-through round hole structure so as to position garlics; the center of the top of the protective net cover directly faces the center of an alignment chain, and the top grid holes penetrate through the top wall of the protective net cover and the upper portion of the side walls of the protective net cover from front to back. Therefore, thecutting indexes such as the root system cutting rate, the cutting efficiency and the effective cutting force can be remarkably improved.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a device for combined harvesting and root cutting of garlic. Background technique [0002] Garlic is an important economic crop and a very competitive foreign exchange earning product in China. The perennial planting area, output and export volume of garlic in my country rank first in the world. In recent years, due to the rising cost and high labor intensity of manual harvesting of garlic, the cost of garlic production remains high, and farmers have an urgent need for garlic mechanized harvesting equipment. At present, there is no garlic combined harvesting equipment in the domestic market, and a few garlic combined harvesting prototypes are still in the research and development stage. The main reason is that the technical problem of mechanized root cutting has not been solved. Mechanized root cutting is the main problem that garlic combined harvesting equipment urgently ...
