An automatic multi-way control valve includes a valve body, a motor, a machinery transmission, an automatic control and a display part. The valve body includes a base and a piston component. The valve base is a plastic part composed of a plurality of water flow passages. The piston component moves up and down to different positions, which makes the water flow through the given passage on the piston base and consequently forms various working situations. The automatic multi-way control valve has the following characteristics: a, the motor is a direct current motor and a driven motor is provided with a photoelectric sensor and a hall element; b, the display part adopts the liquid crystal displays; c, a piston pull rod and an operational function module have an electromechanical connection. The invention has the advantages of small bulk, agile use, convenience and multiple parameters.

The invention relates to a track type garlic seeding machine based on hydraulic transmission. The track type garlic seeding machine mainly comprises a machine head and a seeding machine hinged to the machine head. Tracks are arranged on the two sides of the machine head, and the machine head is provided with a hydraulic power source capable of driving the tracks. The seeding machine is provided with a seeding machine frame. The seeding machine frame is provided with a seeding mechanism, and a rotary cavitation mechanism is installed in the seeding machine frame. The rotary cavitation mechanism comprises a cavitation device frame, a cavitation device installed on the cavitation device frame and a cavitation power unit for driving the cavitation device frame. The cavitation power unit converts hydraulic power coming from the machine head into mechanical power to drive the cavitation device frame to move up and down, and the cavitation power unit further drives the cavitation device to rotate to perform cavitation. The hydraulic power source simultaneously drives the tracks, the cavitation power unit and the seeding mechanism and makes the tracks, the cavitation power unit and the seeding mechanism perform synergic movement, so that garlic seeds are sown out of the seeding mechanism and then fall into seed holes dug by the cavitation device, and the seeding is finished.

The invention discloses a method for realizing an electric proportional control hydraulic multi-way valve. An electric proportional hydraulic control device is respectively installed at one end of each reversing unit of the multi-way valve, and the electric proportional hydraulic control device converts the rotational motion into The rotary motion is proportional to the linear motion, and then the signal provided by the drive unit is amplified by the servo hydraulic unit to drive the main valve core of the multi-way valve to realize the electric proportional control of the multi-way valve. The electric proportional control hydraulic multi-way valve obtained through the technical solution of the present invention can solve the problems of the existing electric proportional multi-way valve that the implementation cost is high, the control algorithm is complex, and it is not easy to popularize and apply in a large area.

The invention discloses a box type flexography unit. The box type flexography unit comprises a bottom roller installed on large wallboards on the two sides. The bottom roller is used as a printing platform of a material film, and the smoothness of the material film and the printing quality are ensured. The bottom roller is connected with bottom roller bearing seats installed on the large wallboards on the two sides through bottom roller bearings. The large wallboards on the two sides serve as a rack of the whole unit. The large wallboards and a lower wallboard are connected into a whole to serve as a foundation bearing the unit. A servo motor is installed on an upper box. A spindle of the servo motor is connected with a transmission shaft through a coupling, so that the spindle of the servo motor rotates to drive a printing roller to rotate, the phase position of the spindle is controlled through the servo motor to control the phase position of the printing roller. An encoder is further arranged on a printing roller servo motor support. An encoder transmission belt pulley and an encoder belt pulley perform transmission with the transmission ratio being 1 to 1, so that transmission signals of the printing roller are collected through the encoder. The problems that the equipment is influenced and maintenance is inconvenient due to transmission outleakage and printing ink splashing of flexographic devices in the prior art are solved.
