It is dynamic；
The discharging switching device of feeding includes swing arm, discharge piston, feeding piston, rotating shaft, driver and seal assembly, it is described go out
Material piston and feeding piston are fixed in swing arm, and are placed in together with swing arm inside hopper, the driver by rotating shaft with
Swing arm is connected, and the seal assembly is arranged between rotating shaft and hopper；
The outlet of the hopper is connected with delivery pipe, and the spout of the hopper connects with prepackage sizer, and the of the hopper
Three mouthfuls are connected with conveying cylinder, and the conveying cylinder, hopper, delivery pipe are linearly arranged.
Further, the main driving cylinder is hydraulic drive cylinder.
Further, the seal assembly is operating pressure >=21MPa high-pressure sealing component.
Further, the driver is hydraulic unit driver.
Further, the hydraulic unit driver is high torque motor or the linkage of hydraulic oil cylinder driving.
Further, the control to main driving cylinder or driver can carry out corresponding delays time to control according to rate of pumping, with drop
Low swing arm motion resistance.
Beneficial effects of the present invention：Driver is connected by rotating shaft with swing arm in pumping installations, and driving piston is in spout
Toggled between discharging opening, realize suction and the extrusion of conveying cylinder material, it is compared with prior art, simple and reliable for structure,
Conveying cylinder is linearly arranged with delivery pipe, can effectively reduce the flow resistance of sludge, energy-conservation, and noise is low in pumping procedure, commutates
Jerk is small, can reduce itself abrasion of equipment in pumping procedure, improves the reliability and service life of equipment.
