Design and Experiment of a Replant Crops Separating Garlic Harvester

Abstract

Background: Garlic is one of the main economic crops in China and the planting area is increasing quickly. But the harvest process of the garlic mainly relies on manual digging, resulting in low harvest efficiency and high cost. Objective: In order to improve the efficiency of garlic harvest, and achieve the mechanization of garlic harvest. The study presents a new design of a garlic harvesting machine that can perform automatic processing and deal with the issue of garlic harvesting. Methods: Firstly, the three-dimensional model of the whole machine and the key mechanism is established and the parameters of the system are calculated by theoretical calculation. Then, the simulation be made and the design be optimized. Finally, the design was processed into a product. It employs an isolation mechanism and positioned cutting mechanism to isolate garlic and crop stubbles and keep the length of the remaining garlic straw consistent. Results: The results of field harvest experiments show that the miss digging rate, miss cutting rate and injury rate of the harvester are as low as 1.23%, 3.13% and 0.68% respectively, and the harvest efficiency is 0.06km2/h. Conclusion: The advantages of the harvester such as high harvesting rate, low damage rate, strong adaptability and high versatility, effectively improve the working efficiency, reduce the labor intensity and the harvest cost.

Design and Test of a Single-Row Harvesting and Cutting Integrated Handheld Garlic Harvester

“…There is a low level of mechanization of the whole garlic process in China; the mechanization level of garlic sowing and harvesting in China is less than 5% and 20% [14,15], respectively. The harvesting of garlic in China still involves manual digging, picking, and processing, resulting in high labor intensity and low harvesting efficiency, which limits the development of garlic cultivation in China [16]. Manual harvesting cannot meet the requirements of harvesting effectiveness, and it is an inevitable choice to mechanize harvesting in the main garlic growing areas in China, given the large area and wide range of garlic cultivation [17,18].…”

Towards Optimizing Garlic Combine Harvester Design with Logistic Regression

“…The mechanization level of garlic production in China is low, especially for the mechanization level of the harvesting link, harvesting link, which is less than 3%. The existing harvesters are mainly mining a ing ones, and the application of combine harvesters is very difficult [22][23][24][25][26][27][28][29][30]. The industry in China is an advantageous industry with strong international competitiv It plays a significant role in promoting Chinese economic growth and helps farm come rich.…”
