This invention belongs to the field of hydraulic technology, specifically relating to a closed-loop motor hydraulic circuit and its control method, as well as a working machine. The closed-loop motor hydraulic circuit includes a hydraulic motor, a hydraulic pump, and a motor bypass oil circuit. The motor bypass oil circuit connects the inlet end and outlet end of the hydraulic motor and is equipped with a regulating valve for controlling the flow rate of the motor bypass oil circuit. The control method of the closed-loop motor hydraulic circuit includes the following steps: obtaining a speed control command for the hydraulic motor; adjusting the rotational speed of the hydraulic motor when the speed value corresponding to the speed control command is greater than a preset speed, and limiting the pressure at the inlet end of the hydraulic motor by controlling the regulating valve; adjusting the rotational speed of the hydraulic motor when the speed value corresponding to the speed control command is less than or equal to the preset speed. The above-described control method for the closed-loop motor hydraulic circuit enables precise and stable adjustment of the rotational speed and the pressure at the inlet end of the hydraulic motor.

This utility model discloses a multi-branch starch slurry conveying pipeline device for clogging prevention, relating to the field of conveying equipment. The utility model includes a conveying pipeline body, which comprises branch pipelines and a main pipeline. A set of guide vane mechanisms is provided inside the connection between the main pipeline and the branch pipelines. The guide vane mechanism includes a base, a transmission rod, and a rotating rod. The base is embedded in the lower part of the pipeline, and guide vanes are provided on the surfaces of the transmission rod and the rotating rod. This utility model achieves automated adjustment of the guide vanes through the linkage design of the guide vanes, the reduction motor, and the flow sensor. This stabilizes the liquid flow state in the branch pipelines while reducing impact pressure on the pipeline, extending pipeline lifespan, and shortening maintenance cycles. Furthermore, the flow guiding function of the guide vanes further realizes basic flow distribution, simplifying the fine adjustment process of the valves.

This utility model relates to the field of sorting machine suction nozzles, and more particularly to a sorting machine suction device with a buffer structure. It includes a first buffer assembly and a second buffer assembly; the first buffer assembly is disposed on a base plate, and the second buffer assembly is connected to a suction nozzle; the first buffer assembly has a sliding mechanism, a portion of which is fixed to the base plate, the base plate is connected to another portion via a first buffer member, and the other portion is connected to the second buffer assembly; the second buffer assembly has a suction nozzle fixing block connected to the suction nozzle, and a second buffer member is abutting between the suction nozzle fixing block and the suction nozzle; the first and second buffer members have the same deformation direction. This application transforms the contact between the suction nozzle and the material into a flexible contact by synchronously deforming the first and second buffer assemblies in the same direction, effectively reducing impact pressure and protecting fragile materials; its guide rail-slider mechanism ensures precise linear guidance and reliable operation during the buffering process.
