“…The clamping chain uses a four-part sharp-tooth chain to effectively hold the garlic seedlings, and each side of the chain is held in place by five four-part sprockets. Four of the quarter sprockets are fully fixed, and the other quarter sprocket can be adjusted to keep the quarter chain taut to ensure the efficiency of the clamping and transportation device [35]. The clamping and transporting device was designed with a 40 • inclination angle, low in the front and high in the back, and the soil on the garlic was shaken off by the machine's forward movement while clamping and transporting so that the garlic could be harvested more easily and cleanly.…”

“…To solve the resistance generated between the surface of the workpiece of the singlerow harvesting and cutting integrated handheld garlic harvester excavating shovel and the land, it is calculated that approximately 60% of the traction power of the engine must be consumed. The acceleration resistance Ff of the soil to the breaking shovel is typically calculated using the following formula [35]:…”

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.

“…China ranks first in the world in garlic cultivation area and total production, and is the largest garlic producer in the world [1][2]. However, the mechanized harvesting technology of garlic in China is backward and still dominated by manual harvesting, which restricts the development of garlic industry [3][4]. 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].…”

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 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.…”

In this paper, a garlic combine harvester machine was designed and some influential parameters of the machine were optimized. The working parts of the machine mainly consisted of a reel, a reciprocating cutter, a seedling conveyor, a profiling depth-stop device, a digging shovel and a lifting chain. Each part had unique structural parameters and motion parameters, as different parameters would deeply affect the performance of the machine. A logistical regression algorithm was utilized to analyze the working speed of the reel, the digging depth of the reciprocating cutter and the lifting speed of the lifting chain. This paper also discussed the influence of these three functions on the damage rate based on the collected data when harvesting garlic. Specifically, each function was tested 60 times for collecting data. The experimental results showed that the order of influence of the three functions on the damage rate was the digging depth, working speed and lifting speed. Moreover, the lowest damage rate was 0.18% when the digging depth was 100 mm, the working speed was 1.05 km·h−1 and the lifting speed was 0.69 m·s−1. A validation test was taken out based on the three functions of the analysis results, and the damage rate was 0.83%, which was close to the analysis results, and proved that the analysis results were accurate and meaningful. The research results are beneficial to the development and application of the garlic combine harvester.
