Detailed Description

The utility model will be described more fully hereinafter with reference to the accompanying drawings.

As shown in fig. 1-2, a feeding device of an automatic proportioning film coating machine comprises a driving motor 1, a screw shaft 3, a material conveying cylinder 4 and a plunger pump 9, wherein the screw shaft 3 is rotatably connected in the material conveying cylinder 4, one end of the screw shaft is fixedly connected with a power output shaft 2 of the driving motor 1, and a sleeve 8 is detachably connected between the driving motor 1 and the material conveying cylinder 4 and used for fixing the relative position of the driving motor 1 and the material conveying cylinder 4.

Feed inlet 5 has been seted up at the top of feed delivery cylinder 4, and feed inlet 5 top intercommunication has feeder hopper 6, can conveniently feed delivery cylinder 4 and the feed bin intercommunication of storing the fertilizer granule through feeder hopper 6, makes the fertilizer granule continuously get into in feed delivery cylinder 4, and feed delivery cylinder 4 keeps away from the one end bottom of driving motor 1 and has seted up discharge gate 7, and screw axis 3 pushes the fertilizer granule to the discharge gate from the feed inlet, falls into the diolame machine.

Plunger pump 9 includes inclined plane disc 10, pressure tube 11, piston 12, piston rod 13 and spring 14, inclined plane disc 10 slope is fixed on power output shaft 2, pressure tube 11 parallel arrangement is in power output shaft 2 below, and pressure tube 11 is located the right side of inclined plane disc 10, piston 12 seals the slip setting inside pressure tube 11, spring 14 sets up between pressure tube 11 right side wall and piston 12, piston rod 13 right-hand member fixed connection piston 12, piston rod 13 has the gliding trend of left side under the spring 14 spring force effect, consequently, the left end of piston rod 13 and the inclined plane in close contact with of inclined plane disc 10.
