The discharging switching device of feeding includes swing arm, discharge piston, feeding piston, shaft, driver and seal assembly, institute
It states discharge piston to be fixed in swing arm, and be placed in inside hopper together with swing arm with feeding piston, the driver is by turning
Axis is connect with swing arm, and the seal assembly is mounted between shaft and hopper；
The outlet of the hopper is connect with delivery pipe, and the spout of the hopper is connected with prepackage sizer, the hopper
Third mouth connected with conveying cylinder, the conveying cylinder, hopper, delivery pipe are linearly arranged.
Further, the main driving cylinder is hydraulic drive cylinder.
Further, the seal assembly is the high-pressure sealing component of operating pressure >=21MPa.
Further, the driver is hydraulic unit driver.
Further, the hydraulic unit driver is high torque motor or the link mechanism of hydraulic oil cylinder driving.
Further, corresponding delays time to control can be carried out according to rate of pumping to the control of main driving cylinder or driver, with drop
Low swing arm motion resistance.
The beneficial effects of the utility model：Driver is connect by shaft with swing arm in pumping installations, and driving piston is being fed
Toggled between material mouth and discharge port, realize conveying cylinder material sucking and extrusion, compared with prior art, it is simple in structure can
It leans on, conveying cylinder is linearly arranged with delivery pipe, can effectively reduce the flow resistance of sludge, energy saving, and low noise in pumping procedure is changed
It is small to jerk, itself abrasion of equipment in pumping procedure can be reduced, improves the reliability and service life of equipment.
