Description

Self-propelled Garlic Combine Harvester

technical field

The utility model relates to the technical field of agricultural combined harvesting machinery, in particular to a self-propelled garlic combined harvesting machine.

Background technique

my country is the main garlic producer, consumer and exporter in the world. The total area of garlic planted every year is more than 10 million mu, among which the area of garlic planted in Shandong Province accounts for more than 40% of the total area of the country. Garlic planting is generally done through the application of base fertilizer on the land. , plowing, furrowing, seed selection, planting, mulching, watering (fertilizing), field management, harvesting, post-harvest picking and processing (removing garlic stalks and garlic roots), grading and other production links. At present, there are two main methods of garlic harvesting: 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. The other is harvesting with excavating machinery. The characteristics of the existing garlic harvesting machinery are as follows: the excavation method is used, that is, the flat shovel (there are paired row loosening shovel type and non-aligned row full-width flat shovel type) or rotary disc cutter Garlic is excavated from the soil. The disadvantages of this excavation method are that the excavation depth is not easy to control, resulting in the phenomenon of garlic cutting and garlic injury. At the same time, it is easy to be congested during operation. At the same time, due to the difference in agronomy in different places, there are differences in row spacing and plant spacing. Poor performance, unreliable quality, etc., most of them have not been mass-produced and widely used. Although some garlic excavators are equipped with a soil-shaking conveyor chain, the excavated garlic is shaken and laid out, and then manually picked up. 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 collapse. In addition, most of the existing garlic planting patterns are mulched with plastic film, and there is residual plastic film when garlic is harvested, so when digging operations, multiple rows are gathered into piles, resulting in winding accumulation, which is not conducive to picking operations. At present, there is no self-propelled garlic harvesting machine that is suitable for various planting row spacings and can complete operations such as digging, transporting, cutting off garlic stalks and roots, and collecting garlic in containers at one time. , Improving production efficiency and increasing farmers' income have important and practical significance.
