“…The mature garlic plant consists of leaves, shoots, stems, bulbs, and roots, among which the bulbs are the main edible parts of the garlic plant, known as "garlic heads" in our daily life [5][6]. At present, China's garlic combine harvester is still in the prototype testing stage and there is no high-performance garlic combine harvester that can complete the operational processes of garlic shoveling and plucking, root and stem removal, cleaning and bulb collection [7][8][9][10]. Although there are some advanced garlic combined harvesting equipment in developed countries, the bale type and stem cutting type garlic combine harvester are also dominant.…”

“…Although there are some advanced garlic combined harvesting equipment in developed countries, the bale type and stem cutting type garlic combine harvester are also dominant. Meanwhile, due to the large gap between China's garlic production conditions, planting patterns, and garlic varieties and developed countries, their advanced equipment is not suitable for mechanized garlic harvesting in China, which is not only expensive but also poor in actual field operation [11][12][13].…”

In order to solve the operational quality problems such as high injury rate, low root removal rate and long residual stems in China's garlic combine harvest, and to improve the performance of root and stem removal operation for garlic combine harvester, a garlic root and stem removal device was developed. A three-factor, three-level orthogonal test was conducted on key parameters affecting the quality of root and stem removal, such as conveying speed, clamping height and clamping angle, through bench tests. The results of the bench test showed that the main and secondary factors affecting the quality of root and stem removal were conveying speed, clamping height and clamping angle, and the better parameter combination was conveying speed of 0.8 m/s, clamping height of 135 mm and clamping angle of 65°. In order to assess the field harvesting quality of the root and stem removal device, a garlic combine harvester was designed, and a prototype was completed for trial production. Through field harvest test, the operational quality of the root and stem removal device was examined in focus. The field test results showed that the device met the quality requirements for garlic combine harvesters.

“…The garlic excavation, soil cleaning, transportation, straw cutting, and collection steps have been highly mechanized in Western European countries and Japan [24]. However, they are not suitable for the closed cropping pattern used in China, and foreign machines are too large and expensive for harvesting operations in domestic garlic cropping patterns [25,26]. China introduced the Japanese Yanmar H1Z garlic harvester in 2019 to fill the gap of mechanized garlic harvesting in Tianjin.…”

“…The loss rate and injury rate of garlic in operation were less than 1.5%, and the total operation time was 131 h, with two failures, a total time of 2.5 h for fault diagnosis and repair, and an average time between failures of 55.5 h. The reliability of use was 98%. Ding Anlan [32] and Peng Baoliang et al studied the design of a machine vision-based automatic digging depth control system for garlic combine harvesters based on the principle of visual recognition and regulation, and Chaoyang Yu [25] and Ke Yang et al studied the parameter optimization and simulation analysis of the floating root cutting mechanism of garlic harvesters based on the root cutting principle. In recent years, China has also developed the 4DBL-2 successively in combination with mature foreign technologies.…”

The current situation in which garlic cultivation is non-homogeneous and modular cannot be adapted to combine harvester operations. In this paper, a single-row harvesting and cutting integrated handheld garlic harvester is designed, and the structure and working principle of the machine are described. By analyzing the mechanics of the machine mechanism, mechanics of the machine harvesting process, and design principle of the machine chassis, the key factors affecting the garlic harvesting machine wounding rate, leakage rate, and net harvesting rate were determined. According to the force and parametric analyses of the test results, it was determined that the machine had the best harvesting effect with a conveying speed of 0.6 m/s, prop speed of 125.6 r/min, digging angle of 15°~25°, forward speed of 0.8 m/s, clamping point height of 62.15 mm, and rollover threshold value of 0.89. Compared with the traditional garlic harvester, the garlic injury rate was 57.1% lower, the garlic leakage rate was 25% lower, and the net harvest rate was 4.0% higher, which meets the requirements of the garlic harvesting operation.

“…To date, many universities and research institutions have carried out research on the garlic-root-cutting mechanization, focusing on solving the technical problems of garlic-rootcutting machinery [4][5][6]. Aiming at the automatic orientation and conveying of garlic-root cutting, the existing equipment adopts a vibration method for feeding [7], which has a poor orientation effect on garlic without stems and requires further manual adjustment.…”

Aiming at the problem that the existing garlic-root-cutting equipment requires the orientation and orderly conveying of garlic, a garlic orientation and orderly conveying method based on machine vision and mechanical orientation mechanisms was proposed and a garlic orientation and orderly conveying device was designed. To realize garlic posture recognition, garlic and garlic roots were used as detection objects, the YOLOv5s objection detection model was used to establish a garlic feature detection model, and the model was trained. The garlic orientation and orderly conveying device was developed and a garlic posture recognition test and garlic orientation and orderly conveying test were completed. The test results show that the success rate of posture recognition is 98.67% and the average accuracy rate of the garlic deviation angle is 99.11%. When the conveying speed is 95 mm⋅s−1 and the rotating speed is 55 rpm, the orientation success rate is 95.6% and the conveying efficiency reaches 75 garlic per minute, which meets the design requirements. The accuracy of the garlic posture recognition method and the rationality of the garlic orientation and orderly conveying device design are verified, and the automatic orientation and orderly conveying of garlic is realized.
