Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

Fig. 1 is the structural schematic diagram of the utility model；It is as shown in the figure: the quantitative feed pump of the present embodiment, including storing Cylinder 8, mounting base 13, pumping mechanism and driving device；The material storage tube 8 is fixed on mounting base 13；Attachment base is equipped with and storing The cavity that 8 inner cavities of cylinder communicate；The pumping mechanism is installed on attachment base under the drive of the drive by material in cavity Pump out；The top opening of the material storage tube 8 is equipped with dismountable cover board 7, and edge is axially arranged with rotatable silk on the cover board 7 Bar 2 has been connected through a screw thread platen 9 on the screw rod 2；The cover board 7 at 8 top of material storage tube can be dismantled, and addition is added after removing Material, then covers cover board 7, and material flows into the interior intracavitary of mounting base 13 by gravity, then pumped out by pumping mechanism, work as storing , can be with rotary screw rod 2 after material in cylinder 8 will be exhausted, screw rod 2 is by its external screw thread, when in a manner of worm drive 9 slide downward of platen, by under the material scraper on 8 barrel of material storage tube, so that material be avoided to remain in material storage tube 8.

In the present embodiment, rubber seal 10 is cased with outside the platen 9；Rubber seal 10 and the barrel of material storage tube 8 are straight Contact, it is ensured that can be clean by the material scraper being attached on barrel.

In the present embodiment, the pumping mechanism includes the plunger pump 15 being set in the mounting base 13, the plunger pump 15 import is located at intracavitary in mounting base 13, the outlet of plunger pump 15 and the outlet of mounting base 13；Object in mounting base 13 Material is entered in plunger pump 15 by 15 import of plunger pump, is then discharged by plunger pump 15 from 13 exit of mounting base.

In the present embodiment, the driving device includes the camshaft 11 being located in mounting base 13, is fixed on camshaft 11 Cam 12 for driving the piston reciprocation of the plunger pump 15 to move, positioned at 13 bottom of mounting base, described convex for driving The motor 14 that wheel shaft 11 rotates.

In the present embodiment, the camshaft 11 is coaxially disposed with the screw rod 2, and screw rod 2 can be displaced downwardly to along axial direction and institute State the transmission connection of camshaft 11；After the supplies consumption in material storage tube 8, screw rod 2 can be pushed, be screw rod 2 and cam Axis 11 is sequentially connected, and drives screw rod 2 to rotate using camshaft 11.The lower end surface of screw rod 2 is equipped with the hole of hexagonal cross-section, camshaft 11 upper end is equipped with the boss cooperated with the hole of the hexagonal cross-section, convenient for the two transmission connection.

In the present embodiment, the screw rod 2 is equipped with bulge loop 3 close to upper end position, and spring is equipped between the bulge loop 3 and end cap 4, the spring 4, which can push up screw rod 2, separates it with camshaft 11；Screw rod 2 is lifted off bias by spring 4 in its natural state Wheel shaft, operator can push screw rod 2, make it that the elastic force of spring 4 and eccentric shaft be overcome to be sequentially connected.
