The sandy loam soil has complex movement characteristics during hole formation by hanging cup transplanters. In order to better investigate this point, the paper aims to investigate the disturbance pattern of transplanter vibration on sandy loam soil and the movement characteristics of soil particles by the discrete element method. The vibration characteristics of the transplanter operating on sandy loam soil were tested and analyzed, and the motion law of vibration parameters on sandy loam soil was investigated with the help of the discrete element method and soil bin test. The results showed that the vibration acceleration of the transplanter increased with the forward speed, the primary vibration frequency range was from 0 to 12 Hz, and the vibration amplitude increased linearly in the field of 1.21 to 9.19 mm. The Central Composite test resulted in the regression equations of vibration amplitude and vibration frequency on the average movement velocity of the particles. The response surface analysis showed that the effect of vibration amplitude on the average movement velocity of particles was greater than the effect of vibration frequency on the average movement velocity of particles. At the same time, the average movement velocity of the particles tends to increase significantly under the interaction of the two. This study provides data to support the design of planters for sandy loam soils, which is beneficial to promote seedling transplanting technology further.

In this paper, the vibration characteristics of the 1ST-460 vibration subsoiler was analyzed. In order to solve the problem of vibration imbalance caused by the vibration component under the action of multiple groups of vibration shovels, the optimal combination mode of the vibration component under the interaction of multiple groups of shovels was obtained. Piezoelectric accelerometers are fixed symmetrically on the frame of the subsoiler to measure the vibration at different positions. TST5910 dynamic signal test and analysis system is used to collect and process the acceleration data. Non-load tests were carried out with different initial eccentric phase angle combination. Results showed that the combination of [0°, 180°, 180°, 0°] (symmetrically up and down staggered vibration) for the eccentric vibration component of four shovels is the optimal initial phase combination, which can lead to the minimum adverse vibration on the frame. Further tests were conducted under different vibrating frequency and amplitude/eccentric with optimal phase combination. The results showed that, when amplitude/eccentricity ratio was 2.0 and 2.5, frequency of vibration was 6.7 and 8.3 Hz, the required traction force of the subsoiler was stable and significantly reduced, which can improve the soil loosening performance and reduce the harmful vibration on the tractor.

Vibration Assessment of a 12-kW Self-Propelled Riding-Type Automatic Onion Transplanter for Transplanting Performance and Operator Comfort

et al. 2023

Vibration assessment of upland crop machinery under development is essential because high vibrational exposures affect machine efficiency, service life of components, degradation of the working environment, and cause health risks to the operator. It is intensively assessed for automobiles as well as large off-road agricultural vehicles (i.e., tractors). However, it is mostly overlooked in the case of the small or medium riding-type upland utility vehicles. Therefore, the vibration exposures of a 12-kilowatt self-propelled riding-type automatic onion transplanter were measured and evaluated to assess the performance of onion transplantation and the operator’s comfort in this study. Different types of driving surfaces, operating statuses (static and driving), and load conditions were considered to analyze the vibration exposure. The precision of transplantations was evaluated while operating the transplanter on the soil surface with different driving speeds and load conditions. Tri-axial accelerometers and a LabVIEW-coded program were used for data acquisition. The vibrational exposures were evaluated based on ISO standards, and power spectral density (PSD) was estimated to assess the major frequencies. According to the statistical analysis, the daily exposure value (A(8)) and the vibration dose value (VDV) varied from 10 to 15 ms−2 and 20 to 31 ms−1.75, respectively, which exceeded the ISO 2631-1 standards (i.e., A(8): 1.15 ms−2 and VDV: 21 ms−1.75). The calculated health risk factor (RA) was moderate. Moreover, a high weighted acceleration (around 8 ms−2) was observed on the seedling conveyor belt, which might result in missing seedlings during transplanting. The vibration exposures of the developed onion transplanter need to be minimized following the ISO standards, and vibration reduction would also improve the market competitiveness.
