This invention discloses a segmented drum screen device for mineral processing, comprising a base, a storage box, a screening machine, and a mounting frame. The storage box and mounting frame are both fixedly connected to the base, and the screening machine is inclinedly positioned on top of the storage box. The screening machine includes a casing, a main shaft, and several circular screens. The main shaft is rotatably connected to the casing. Several connecting rods are fixedly connected between the circular screens and the main shaft. Several screen holes are evenly distributed on the circular screens. Baffles are rotatably connected between adjacent circular screens, and discharge holes are provided on the baffles. A drive gear is fixedly connected to one end of the main shaft, and a drive reduction motor is fixedly connected to the top of the mounting frame. A receiving box is provided inside the storage box, located below the corresponding circular screen. This invention employs a mechanical structure for mineral particle size classification. The inclination degree controls the mineral's movement speed, and the baffles control the classification and discharge speed, ensuring good classification results for minerals at each stage and improving the efficiency of mineral processing and classification operations.

This invention discloses a wheel hub motor-based vehicle steering control method, comprising the following steps: setting the target rotational speed of the wheel hub motors during center turn; employing a common-parameter, different-proportion PI algorithm to calculate the target torque of each wheel based on the difference between the actual rotational speed and the target rotational speed of each wheel hub motor; calculating the sum of the target torques of the left and right wheel hub motors; and obtaining the larger value T of the sum of the target torques of the left and right wheel hub motors. max ; Calculate the sum of the target torques of the left and right motors and T max The algorithm calculates the difference between the left and right wheel hub motors and distributes them according to the percentage of rotational speed among the hub motors on the same side. It also calculates the first, second, and third target torques for each hub motor and sets the rotation directions and target torques for each motor. This algorithm enables the vehicle to steer around its geometric center by rotating the left and right wheel hub motors in both directions, significantly reducing the turning radius and improving the vehicle's passability.

The utility model relates to the field of tobacco packaging, in particular to a cigarette code spraying device which comprises a machine frame, a conveying belt arranged on the machine frame and used for conveying cigarettes and a code spraying mechanism used for spraying codes. The rack is provided with a transverse moving seat transversely moving in the conveying direction of the conveying device, and the rack is provided with a transverse moving driving mechanism used for driving the transverse moving seat to transversely move. A lifting seat capable of lifting up and down is arranged on the transverse moving seat, and a lifting driving mechanism used for driving the lifting seat is arranged on the transverse moving seat; a rotating seat is rotatably arranged on the lifting seat, and a rotation driving mechanism for driving the rotating seat to rotate is arranged on the lifting seat; and a camera for identifying cigarette cartons is arranged on the rotating seat. The technical problems that an existing code spraying device cannot accurately recognize changes of positions, postures, angles and the like of cigarette cartons, and accurate code spraying and clear code spraying cannot be achieved are solved.
