Floating-type seedling dividing and holding mechanism of garlic combine harvester

Abstract

The invention relates to a floating-type seedling dividing and holding mechanism of a garlic combine harvester, and belongs to the technical field of agricultural machinery. The mechanism comprises aharvesting rack and an excavating shovel that extends forwards. The harvesting rack is located on the front portion of the harvester, and the excavating shovel is mounted below the harvesting rack. Seedling dividers are respectively mounted on two sides of the front of the excavating shovel. Each seedling divider comprises a seedling dividing tip, wherein the seedling dividing tip is located at the forefront end of a forwardly-extending seedling dividing rod and is higher than the excavating shovel. Half-encircling tapered seedling dividing plates that extend backwardly are fixed to the rear portions of the seedling dividing tips. Seedling holders are mounted on the rear upper sides of the tapered seedling dividing plates. Each seedling holder comprises a forwardly-extending horizontal-axis disc brush that is driven by a motor above the excavating shovel. The inner sides of the disc brushes on both sides of the excavating shovel rotate in a direction in which the cutting direction faces upwards. The seedling holders gradually pick garlic up by the aid of the tapered seedling dividing plates, the inner sides of the disc brushes on both sides rotate in a direction, in which the cutting direction faces upwards, to lift the garlic up, and the garlic is in a 'lift-up' state to be excavated by the excavating shovel, so that the digging and harvesting quality is effectively ensured, and entanglement is avoided.

Description

technical field [0001] The invention relates to a garlic harvester, in particular to a floating grain dividing and lifting mechanism of a garlic combine harvester, which belongs to the technical field of agricultural machinery. Background technique [0002] Garlic is one of the important economic crops, and its harvesting process includes digging and laying, cutting seedlings, cutting roots, removing soil and cleaning, and collecting and bagging. Because garlic not only has a high planting density, but also has a variety of soil types, mechanized harvesting is difficult. In particular, garlic is often planted with film, and lodging is serious during the harvest period. Therefore, how to lift up the fallen garlic seedlings and avoid bringing up the residual film on the ground before the subsequent harvesting process has become the first problem to be solved in garlic mechanized harvesting. . [0003] According to the applicant's understanding, most of the existing garlic co...

Problems solved by technology

Its unique weed-cutting and healing structure adopts a fixed guide plate to help the grain and a side disc knife to cut off the structure. However, because the lodging of garlic reaches more than 50% during the harvest period, and the lodging direction is messy, although the side cutting can prevent entanglement, but It is inevitable to cut off the garlic seedlings, resulting in the failure of these cut garlic seedlings to be clamped and resulting in losses during the subsequent harvest

[0006] The Chinese patent application number 2018111991152 discloses "A Multi-row Garlic Combine Harvester". The front end relies on the floating wheel type to divide the grain and the adjacent flexible gears mesh with each other to help the grain and assist the feeding; but limited by its space Scale limitation, floating wheel is small, it is still easy to cause residual film to be entangled, and flexible teeth are easy to feed the lifted residual film into the clamping and conveying mechanism, resulting in unsmooth follow-up operations

[0007] In a word, the prior art fails to properly solve the problem of lifting up the inverted seedlings while avoiding the entanglement of the plastic film
