Flexible slope leading-in type garlic floating root-cutting device

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a flexible slope leading-in type garlic floating root-cutting device which comprises a floating root-cutting main body part, the floating root-cutting main body part includes a base, a support frame arranged on the base, an upper housing erected on the support frame, a motor fixedly mounted on the lower side of the base, a cutter head, and at least three compression springs; the upper ends of the compression springs are in supporting connection with the bottom of the supporting frame, and the lower ends ofthe compression springs are installed on the upper side of the base; a reference inclined plane is arranged on one side, facing garlic bulbs, of a housing and is connected with the horizontal plane on the upper side of the upper housing, and a rubber plate is attached to the reference inclined plane; a net-shaped structure comprises a plurality of rows of first grid holes in the front rows, a plurality of rows of second grid holes in the rear rows and a middle connecting plate part located between the first grid holes and the second grid holes and separating the first grid holes from the second grid holes. The garlic floating root-cutting device is simple in structure and ingenious in structure, profiling floating cutting in any direction in a three-dimensional space can be achieved, theroot cutting rate and cutting uniformity are remarkably improved, and collision damage between garlic and the garlic floating root-cutting device is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a garlic root cutting device. 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 needs to solve, and i...

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
