A floating garlic root cutting device introduced by roller

Abstract

The invention relates to a floating garlic root cutting device introduced by a roller in the field of agricultural machinery, comprising a floating root cutting main part, which includes: a vertical plate fixed on an alignment chain frame; a pair of swing arms A parallelogram linkage mechanism is formed, one end of the two swing arms is rotated to connect the vertical plate; the base, the other end of the two swing arms is rotated to connect the base; the upper side of the shell base is set as a horizontal structure, and the upper side of the shell base There is a mesh structure, one side of the shell seat is fixedly connected with the base; a motor; a cutter head arranged in the inner cavity of the shell seat; a horizontally arranged copying roller, the copying roller is connected to the base in rotation and is located in front of the front side of the shell seat. The central axis of the profiling drum is its rotation axis, and is perpendicular to the conveying direction of the head of garlic; the tension spring is connected to the alignment chain frame at one end and obliquely pulls the swing arm. It can effectively reduce the collision damage between the garlic head and the root cutting device during root cutting, and improve the root cutting rate and cutting uniformity.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a garlic root cutting device, in particular to a floating garlic root cutting device introduced by a roller. 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 tha...

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
