Garlic combine harvester

Abstract

The invention discloses a garlic combine harvester. The garlic combine harvester comprises a harvester body, a driving device, multiple seedling separators, a soil excavation mechanism, a clamping and conveying mechanism, a cutter mechanism and a collecting device, wherein the cutter mechanism is used for cutting off garlic seedlings; the collecting device is used for collecting and conveying garlic bulbs; the driving device is in driving connection with the harvester body; the clamping and conveying mechanism is movably suspended on the harvester body and has at least two clamping and conveying gaps, an inlet for inputting the garlic seedlings and an outlet for outputting the garlic seedlings are formed in two ends of each clamping and conveying gap, and the inlet is lower than the outlet; each seedling separator is fixed at one end, close to the corresponding inlet, of the clamping and conveying mechanism; the soil excavation mechanism is movably mounted on a rack and is located behind the seedling separators; the cutter mechanism is mounted on the clamping and conveying mechanism and located on the lower side of each clamping and conveying gap; the collecting device is fixed on the harvester body and located below the cutter mechanism. According to the garlic combine harvester, seedling separation, soil excavation, clamping, seedling cutting and garlic bulb conveying and collection of multiple rows of garlics can be completed once, and the adaptability and the reliability are high.

Description

technical field [0001] The invention relates to a garlic combine harvester. Background technique [0002] China is a major garlic producer, consumer and exporter in the world, with a total area of ​​more than 10 million acres of garlic planted each year. At present, domestic garlic harvest mainly has the following three methods: [0003] One is the traditional manual harvesting production method, that is, manual excavation with the help of self-made simple flat shovel, and manual picking and shaking of soil. The defect is that the production efficiency is relatively low. [0004] The other is harvesting with excavating machinery. The characteristics of the existing garlic harvesting machinery are as follows: the excavation method is adopted, that is, the flat shovel (there are paired row loosening shovel type and non-aligned full width flat shovel type) or rotary disc cutter The garlic is excavated from the soil. The disadvantage of this excavation method is that the excav...

Problems solved by technology

[0003] One is the traditional manual harvesting production method, that is, manual excavation with the help of self-made simple flat shovel, and manual picking and shaking of soil. The defect is that the production efficiency is relatively low

[0004] The other is harvesting with excavating machinery. The characteristics of the existing garlic harvesting machinery are as follows: the excavation method is adopted, that is, the flat shovel (there are paired row loosening shovel type and non-aligned full width flat shovel type) or rotary disc cutter The garlic is excavated from the soil. The disadvantage of this excavation method is that the excavation depth is not easy to control, resulting in the phenomenon of garlic cutting and garlic injury, and at the same time, it is easy to be congested during operation; in addition, there are differences in row spacing and plant spacing in different regions. Therefore, due to reasons such as poor adaptability and unreliable quality, most of them have not been mass-produced and widely used; although some garlic excavators are equipped with soil-shaking conveyor chains, the excavated garlic is shaken and laid, and then picked up manually , however, after the garlic sprouts are harvested, most of the upper part of the garlic plant stalks bend and fall, causing the garlic plant stalks to intertwine

In addition, most of the existing garlic planting methods are mulched with plastic film, and there is residual plastic film when harvesting garlic and garlic seedlings. Therefore, when digging, many rows are gathered into piles, resulting in winding accumulation, which is not conducive to picking operations

[0005] Another way is to carry out combined harvesting of garlic and garlic seedlings. The garlic harvesting machine can complete operations such as excavation, transportation, removal of garlic seedlings, and garlic container collection at one time. The existing defect is serious congestion, and the efficiency of 0.2-0.3 mu per hour Low, the cost of machine processing remains high, has no real economic value, and cannot be mass-produced and promoted on a large scale

[0006] Countries such as Europe and the United States realized the mechanization of garlic harvesting as early as the end of the 1960s. Most of the harvesting machines are combined harvesting, and the combined harvesting is mainly traction-type, mostly wheeled tractor chassis, mainly driven by hydraulic pressure; There is a huge difference between the planting method and domestic ones, which makes it impossible for foreign garlic harvesters to be popularized and applied in China
