Floating type garlic root cutting device guided in through roller

Abstract

The invention relates to the field of agricultural machinery, in particular to a floating type garlic root cutting device guided in through a roller. The floating type garlic root cutting device comprises a floating root cutting main body part, wherein the floating root cutting main body part comprises a vertical plate, a parallelogram connecting rod mechanism, a base, a shell seat, a motor, a cutter, a profiling roller and an extension spring, wherein the vertical plate is fixed on an alignment chain rack; the parallelogram connecting rod mechanism is composed of a pair of swing arms, and oneends of the two swing arms are rotationally connected with the vertical plate; the other ends of the two swing arms are rotationally connected with the base; the upper side of the shell seat is of ahorizontal plane structure, a net-shaped structure is arranged on the horizontal plane of the upper side of the shell seat, and one side of the shell seat is fixedly connected with the base; the cutter is arranged in an inner cavity of the shell seat; the profiling roller is horizontally arranged, and rotationally connected with the base and located in front of the front side of the shell seat, and the central axis of the profiling roller is the rotating axis of the profiling roller and is perpendicular to the garlic bulb conveying direction; and one end of the extension spring is connected with the alignment chain rack and obliquely pulls the swing arms. Collision damage between garlic bulbs and the root cutting device during root cutting can be effectively reduced, and the root system cutting rate and the root system cutting uniformity are improved.

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
