“…A higher quality feed index and better precision found in the present study may be attributed to reduced source vibration and skidding effects. The effects of planter vibration on performance have also been reported by Liu et al [13], Zhai et al [14], Yu et al [15], Hou et al [16] and Cujbescu et al [17]. The driving unit, power source, and ground wheel are some of the prime factors producing vibration.…”

The growing demand for agricultural output and limited resources encourage precision applications to generate higher-order output by utilizing minimal inputs of seed, fertilizer, land, and water. An electronically operated planter was developed, considering problems like ground-wheel skidding, field vibration, and the lack of ease in field adjustments of ground-wheel-driven seed-metering plates. The seed-metering plate of each unit of the developed planter is individually driven by a brushless direct current (BLDC) motor, and a BLDC motor-based aspirator is attached for pneumatic suction of seeds. The revolutions per minute (RPM) of the seed-metering plate are controlled by a microcontroller as per the received data relating to RPM from the ground wheel and the current RPM of the seed-metering plate. A feedback loop with proportional integral derivative (PID) control is responsible for reducing the error. Additionally, each row unit is attached to a parallelogram-based depth control system that can provide depth between 0 and 100 mm. The suction pressure in each unit is regulated as per seed type using the RPM control knob of an individual BLDC motor-based aspirator. The row-to-row spacing can be changed from 350 mm to any desired spacing. The cotton variety selected for the study was RCH 659, and the crucial parameters like orifice size, vacuum pressure, and forward speed were optimized in the laboratory with the adoption of a central composite rotatable design. An orifice diameter of 2.947 mm with vacuum pressure of 3.961 kPa and forward speed of 4.261 km/h was found optimal. A quality feed index of 93% with a precision index of 8.01% was observed from laboratory tests under optimized conditions. Quality feed index and precision index values of 88.8 and 12.75%, respectively, were obtained from field tests under optimized conditions.

“…Yu et al designed the key parameters of the arc opener of a wheat no-tillage planter, such as the slope and entry angle, and investigated the opener's resistance at various working speeds [13]. Liu et al expanded the application range of ditching machines by equipping these blocks with chains and blocks of various materials and sizes, such as cup teeth, rock teeth, and frozen soil teeth, based on different soil materials and hardness [14]. The spiral ditching machine was designed and developed to meet the agricultural needs of covering soil in wheat furrows.…”

The existing vertical spiral ditching machine mainly works in flat orchards, and the structural design of ditching components does not match the design of power transmission system, which leads to high ditching power consumption and poor ditching stability. According to the needs of deep application of organic fertilizer in orchards, a spiral cutter was designed to alleviate the common problems of high power consumption and poor stability of ditching machine and reduce the power consumption of ditch cutting. Therefore, the motion parameters and structural parameters of the spiral cutter are optimized. Using ANSYS preprocessor, the finite element model of cutting soil with spiral cutter is established, and the implicit functional relationship between milling force factor and instantaneous cutting thickness is established by using BPNN (BP neural network). On the basis of the established prediction model of milling force, orthogonal experiments were carried out to obtain the best combination of cutter head rotation speed, slotting depth, and advancing speed with minimum power consumption: 20.16 rad/s, 0.3 m, and 0.12 m/s. By investigating the influence of various working parameters on the power consumption of ditching machine, the analysis basis is provided for selecting reasonable working parameters of ditching machine.

The seeder was tested and evaluated for field operations vibration characteristics in light of the issue that the spoon-wheel maize precision seeder vibrates due to the field operating conditions, which impairs the performance of the seed-metering device. During field testing, it was discovered that the seed-metering device vibrated greater as the forward speed increased, resulting in a higher peak vibration acceleration. However, fluctuations in forward speed did not affect the frequency distribution of the peak vibration acceleration. Time-domain and spectrogram investigations revealed that the vibration frequency of the seed-metering device was predominantly within 0~10 Hz for seeder operating speeds ranging from 2~6 km/h, with acceleration values spanning from 0.85~1.86 m/s2. An electromagnetic seeding test stand was established in response to the discoveries. The essential variables governing the seeding performance of the spoon-wheel seed-metering device were then investigated using orthogonal tests, such as forward speed, vibration frequency, and vibration acceleration. The empirical results elucidated a hierarchical relationship between these factors and seeding quality. Specifically, vibration frequency emerged to be the predominant factor, followed by vibration acceleration, and forward speed. The seeding quality of the seed-metering device was negatively correlated with increases in forward speed and vibration acceleration, which led to a lower qualified rate, higher leakage rate, and variation coefficient. Overall, the qualified rate, leakage rate, and variation coefficient were all significantly influenced by the three factors.
