This utility model discloses an integrated machine for laying double-layer plastic film and drip irrigation tape, comprising: a frame; a drip irrigation tape placement shaft mounted on the frame, with two drip irrigation tape rolls sleeved on the placement shaft; a white plastic film placement shaft mounted on the frame, with a white plastic film roll sleeved on the white plastic film placement shaft; a black plastic film placement shaft mounted on the frame, with a black plastic film roll sleeved on the black plastic film placement shaft; and a film pressing shaft assembly mounted on the frame. This integrated machine can lay black and white plastic film and drip irrigation tape completely in one operation, which not only improves agricultural efficiency, but also allows the black plastic film to inhibit weed growth, the laid white plastic film to lower the soil surface temperature and prevent seeds from being burned by high temperatures, while also helping to maintain soil moisture and promote seed germination. The laid drip irrigation tape achieves water conservation and eliminates the need for manual watering.

This invention provides a stacker crane for aisle storage, including a traveling base beam and a stacking device on the traveling base beam. A buffer device is also provided on the traveling base beam, and an adjustment device is installed at the outer end of the buffer device. The buffer device includes a buffer frame on the traveling base beam, with multiple sets of buffer crossbeams fixedly connected to both sides of the buffer frame, defining multiple buffer levels distributed vertically within the buffer frame. Buffer plates are fixedly connected to the multiple sets of buffer crossbeams, and multiple sets of goods are placed on the buffer plates. A conveying component is provided on the buffer plates, and scanning components are provided on the multiple sets of buffer crossbeams. A contact component is provided at one end of each set of buffer crossbeams. This invention improves storage and retrieval efficiency through multi-level buffering and path optimization, achieves real-time monitoring and automatic correction of goods status through intelligent scanning and pressure sensing fusion, and completes high-precision automatic docking based on laser ranging and electromechanical linkage. Ultimately, it constructs a highly efficient, reliable, and fully automated intelligent warehousing and stacking system.

The application discloses a torque control method, device, equipment and medium of an electrically driven vehicle. The method comprises the following steps: acquiring the current rotating speed of the walking driving motor of the electrically driven vehicle in real time; when it is determined that the current rotating speed falls into a torque reduction interval, a target torque control curve is acquired from a plurality of torque control curves, and the output torque of the electrically driven vehicle is adjusted according to the target torque control curve; if the current rotating speed is detected to decrease for the first time during the control process of the output torque according to the target torque control curve, the torque reduction interval is divided into a plurality of hysteresis adjustment intervals according to the rotating speed of the speed reduction point at the time of the first decrease; when it is determined that the torque hysteresis adjustment condition is met according to the real-time rotating speed, the output torque of the electrically driven vehicle is adjusted according to the rotating speed limit value corresponding to at least one hysteresis adjustment interval. According to the torque limiting curve, the application carries out the anti-over-speed control, avoids the back-and-forth fluctuation of the motor torque in the anti-over-speed control process, and improves the driving efficiency and driving comfort.

The application provides a profile automatic feeding and discharging control method, a feeding trolley is moved to clamp a first profile located at a first roller table station, and the first profile is dragged along a feeding roller table until the first profile is completely dragged onto the feeding roller table; after the first profile is cut, a roller bracket is moved to align a second roller table station with a discharging port of a cutting mechanism, and meanwhile, the first roller table station is away from the discharging port of the cutting mechanism; the feeding trolley is moved to clamp a second profile on the second roller table station, and the second profile is dragged along the feeding roller table until the second profile is completely dragged onto the feeding roller table; and during the cutting of the second profile, the first workpiece on the first roller table station of the roller bracket and the remaining first profile excess material are cleaned. The automatic feeding and discharging are realized at the same position, the mechanical structure is greatly simplified, the equipment manufacturing cost is reduced, and the profile cutting efficiency is improved.
