“…Chen et al [37] studied that the primary components of a silage maize harvester are horizontal feeding devices and plate hob cutting equipment. In order to address the issues of obstruction in the feeding process, high energy consumption, and subpar chopping quality, a horizontal different diameter five-rollers device (HDDFD) was developed.…”

The effectiveness of maize harvesting is significantly impacted by the parameters of snapping rollers, which have a crucial function in separating maize ears from the stalks. The present study examines the influence of several snapping roller parameters, such as rotational speed, roller spacing, and surface properties, on the efficiency of maize harvesting. The paper provides a detailed examination of the advancements in snapping roller technology, focusing on improvements that seek to optimize performance and minimize harm to crops. The research highlights significant obstacles, including the need for wear resistance, careful material selection, and the capacity to adapt to various maize kinds. The suggested solutions to these difficulties include the use of improved materials, optimal roller designs, and adaptive control systems. Addressing these difficulties may lead to a substantial improvement in the efficiency and sustainability of maize harvesting operations, as shown by the data. This study offers vital insights for the development of more efficient and durable maize harvesting machinery, eventually leading to enhanced agricultural output and food security.

“…are not significant. 6.1.2 Two-factor interaction effect analysis 1) Effect of two factors on lodging rate The response surface curve for the effect of interaction factors was obtained by applying Design-Expert 8.0 software for analysis [18] . As shown in Figure 10, at an operating speed of 1.1 km/h ,the lodging rate increases with an increase of the operating speed when the cutting speed is fixed, and the lodging rate is minimum when the cutter height is -4.0 cm.…”

Recognizing the labor intensity of current domestic Chinese chive harvesting and the need for its mechanized harvesting, a self-propelled electric Chinese chive harvester is designed. The machine is composed of a control system, supporting mechanism, cutting parts, conveying and clamping mechanisms, frame, and collection system. It can complete Chinese chive feeding, cutting, transmission, and binning operations at one time. It has a cutting width of 0.25 m and wheelbases of 260 mm and 460 mm. Two 12 V, 42 Ah lead-acid batteries were used in series as the power supply. The mechanical properties of Chinese chive were analyzed, and shear and compression tests were carried out to determine that the average value of the maximum shear force on the chives is 129 N. Up to a compressive force of 225 N, Chinese chives are not damaged. According to the physical characteristics of Chinese chives and the requirements of the harvesting operations, design and calculation of the key components of the harvester's transmission mechanism and the strength of the whole machine frame were completed. An embedded control system and Cortex-M3 microprocessor were used to control the harvester and realize its functions of rolling and harvesting while regulating its speed and protecting its motor. Using the Box-Behnken test design method, the machine's operating speed, cutter speed, and cutter height were selected as influencing factors, and the lodging rate and loss rate were evaluated as a test. A mathematical regression model of influencing factors and evaluation indexes was established to analyze the influence of these factors and indexes and optimize test parameters. The optimal parameter combination is determined to be: operating speed, 1.1 km/h; cutter speed, 220 r/min; cutter height 2.0 cm. The parameters were verified from field tests and the results showed that under the optimized parameter combination, the average lodging rate was 3.96% and the average loss rate was 3.23%, indicating that the Chinese chive harvester meets the agronomic requirements of Chinese chive harvesting. This harvester could be modified to harvest other crops such as chrysanthemums and Mongolian Chinese chive.
