Coal is the main source of energy in China, and coal washing and processing can reduce the impurities in coal, which is particularly important for environmental protection and efficient utilization of coal. Mining vibrating screen in the coal selection process plays an important role, due to the harsh working environment of the coal plant, the work intensity is large, making the mining vibrating screen is very easy to fail, resulting in huge economic losses, which can cause serious injuries. Therefore, the monitoring and diagnosis of mining vibrating screen failure research is of great significance. In this paper, the mining vibrating screen SOLIDWORKS three-dimensional modeling, the use of ANSYS software for modal analysis, through the modal analysis, the mining vibrating screen to get the first 12 orders of modes, to determine the mining vibrating screen in the first 12 orders of modal vibration under the intrinsic frequency and intrinsic vibration pattern, for the mining vibrating screen research provides an important basis.

“…In the agricultural machinery industry, screens are commonly used in harvesting devices [5] and cleaning devices [6]. In the study of harvesting devices, researchers always analyze the separating performance [7,8], net harvesting performance [9], or loss rate of the vibrating screen [10,11]. However, the particle conveyance ability is also very important and rarely studied.…”

The problem of soil and Chuanxiong tuber congestion on vibrating screens usually exists during the Chuanxiong mechanized harvesting process. To address this problem, the conveyance performance of a crankshaft rocker vibrating screen was studied. By establishing and solving the dynamics and kinematics equations for the crankshaft rocker vibrating mechanism and Chuanxiong soil residue, the acceleration of the vibrating screen and Chuanxiong-soil residue was studied. The sliding speed, motion process, and conveying distance of the Chuanxiong soil residue were also analyzed. The theoretical analysis results indicated that the acceleration of the vibrating screen depends on the rod lengths of the vibrating mechanism and the crank rotational speed and position. The displacement of the Chuanxiong-soil residue along the positive sliding direction in a cycle was more significant than that of the negative sliding direction. The appropriate advancement speed of the harvester was also obtained. The RecurDyn and EDEM coupling simulation was conducted. The simulation results verified the theoretical analysis. In the simulation, the Chuanxiong-soil residue was effectively conveyed. The field tests were conducted to verify the theoretical analysis. The harvester was tested in the field with crank rotational speeds of 0 r/min, 120 r/min, and 240 r/min, and advancement speeds of 0.5 m/s, 1 m/s, 1.5 m/s, and 2 m/s. The results showed that there was no congestion in the screen during the working process when the rotational speed of the crank was 240 r/min, and the advancement speed of the harvester was no faster than 1.5 m/s. When the crank rotational speed was 240 r/min, and the advancement speeds were 0.5 m/s, 1 m/s, and 1.5 m/s, the weights of Chuanxiong and soil on the screen after the test were 71.5 kg, 84.7 kg, and 105.7 kg, respectively. The field tests verified the conveyance performance of the vibrating screen. This study can provide a theoretical reference for designing the crankshaft rocker vibrating mechanism for the rhizome harvesting machine.
