This invention relates to the field of agricultural machinery technology and discloses a mechanism for adjusting the speed of a star wheel. The mechanism includes a steel frame with star wheel shafts evenly distributed from bottom to top. Star wheel bodies are evenly fitted onto the star wheel shafts along their axial direction. Sprockets and chains are provided between adjacent star wheel shafts. A hydraulic motor is mounted on the outside of the steel frame. The mechanism also includes a centrifugal wheel, with its main body fixed to one end of the star wheel shaft. A radial groove is formed on the centrifugal wheel, and a centrifugal counterweight and a cam are connected within the groove via a first serpentine spring. The main body is connected to one end of the star wheel shaft via a bearing, and a first torsion spring is provided between its outer wall and the star wheel shaft. A connecting arm is provided between the cam and the centrifugal counterweight. The mechanism utilizes a hydraulic motor to independently drive the star wheel, achieving stepless speed regulation. Through the triple synergistic effect of centrifugal force adaptive clamping force adjustment, automatic jamming clearance, and eccentric linkage vibration unblocking, it effectively prevents the star wheel body from jamming and corn kernel damage, resulting in a high peeling rate, low kernel loss rate, and stable operation.

The invention belongs to the technical field of capacitor electrolytes, and particularly relates to an electrolyte, a preparation method thereof and an aluminum electrolytic capacitor. The electrolyte comprises a main solvent, an auxiliary solvent, a solute, an auxiliary solute and a sparking voltage boosting agent, the sparking voltage boosting agent comprises super-hydrophilic nano modified silicon dioxide sol, and the mass percent of the sparking voltage boosting agent is 10%-18% based on the total mass of the raw materials forming the electrolyte. The super-hydrophilic nano modified silica sol is added into the electrolyte, so that the reduction rate of the conductivity of the electrolyte after high-temperature storage is reduced, the sparking voltage of the electrolyte after high-temperature storage is basically kept at a level equivalent to that of the electrolyte before storage or even higher than that of the electrolyte before storage, and the high-temperature storage performance of the electrolyte is obviously improved.
