To address prominent issues in the spring soil removal process for wine grapes in northern China, such as incomplete soil clearing, vine damage, and low operational efficiency, a dual-sided soil removal machine combining scraping, rotary, and vibration functions was designed and developed. The machine primarily consists of a gantry frame, rotary soil components, scraping components, and vibrating components. Using EDEM 2020 discrete element software analysis and Design-Expert 13 orthogonal experiments, a three-factor, three-level orthogonal simulation experiment was conducted, with rotary soil component speed, scraping component angle, and vibrating component frequency as test factors and soil removal rate as the evaluation index. The optimal operating parameters were determined: rotary soil component speed at 720.6 r/min, scraping component angle at 42.4 degrees, and vibrating component frequency at 179.1 Hz, yielding a soil removal efficiency (K value) of 83.48% and the best simulation results. A physical prototype was manufactured, and field experiments were conducted, resulting in an actual soil removal rate of 76.81%, with a deviation of 7.09% from the simulation results. The field test results were consistent with the simulation data, and the exposed vines in the field after soil removal met the operational requirements for actual production. The research outcomes of this machine provide a reference for the further development of dual-sided soil removal equipment for wine grape vines.

Carpets are widely used in living spaces for beautiful appearance, heat, and sound insulation. Cleaning carpets is essential for both their lifespan and health and hygiene. Washing operations are carried out at regular intervals in carpet-washing factories.Industrial carpet washing operations must be done consciously because a significant amount of water and time is consumed during these processes. In addition, problems such as discoloration and strength losses may be encountered in delicate carpets. In this study, stained carpets were washed at mediums with and without ultrasound at room temperature at different times. Mud stain was used as an example of particle dirt. The original unwashed carpet without stain was taken as a reference and compared with the washed carpet by evaluating the color differences and changes in the yellowness indexto check the amount of stain removal. The color differences (Da*, Db*, DL*, DC*, Dh*, DE*) were close to zero, and the differences in the yellowness index were low, so it was concluded that the stained carpet was cleaned and turned to the original form after washing. The washing process was evaluated as successful because the color and yellowness index of the washed carpet were close to the unwashed carpet. Effects of washing type (with and without ultrasound), washing agent (with and without detergent), and washing time (30, 60, and 90 minutes) are significant for alpha=0,05 in washed carpets according to the original carpet. Interactions between parameters are also significant. If the washing conditions are consciously adjusted, ultrasonicwashing can be an alternative to the soaking process in carpet washing.With ultrasonic washing, it can be possible to shorten the duration of the wetting step and effectively clean sensitive carpets in softer conditions without damaging them.It would beuseful to carry out studies that reduce water usage by optimizing the amount of washing baths in the future.
