The beneficial effects of the utility model are: the described axle that long cylinder is arranged on the pedestal with support is a piston, be arranged on the pedestal, and the cylinder of losing heart that is serially connected, the piston rod and the pump housing are arranged on the pedestal, cause that when the pressure change in the long cylinder long cylinder is along the axle of support when mobile, pedestal also can move thereupon, the cylinder of losing heart, the piston rod and the pump housing also can move thereupon, when shield tail grease pump of the present utility model is placed in the grease tank, pedestal can be configured to be positioned on the pasta, when pasta descends, because long cylinder can act on the pedestal a downward power all the time, thereby the above part of the pedestal of shield tail grease pump all can descend along with the decline of pasta, end to the interior grease of grease tank and running out, one collision block is set on piston rod, clash into the position limit switch of a selector valve by collision block, thereby can realize the oil suction of the pump housing and the switching of oil extraction easily.
Description of drawings
Fig. 1 is an an embodiment's of the present utility model structural drawing.
Embodiment
As shown in Figure 1, an embodiment of the present utility model comprises a pedestal 15, the upside of pedestal 15 is provided with long cylinder 14, the lose heart cylinder 11 and the pump housing 10, lose heart cylinder 11 and the pump housing 10 shared piston rods 13, lose heart cylinder 11, piston rod 13 and the pump housing 10 serial connections, and the cylinder 11 of losing heart is positioned on the pump housing 10, so just can control the process of the oil suction or the oil extraction of the pump housing 10 by lose heart air pressure in the cylinder 11 of control.Long cylinder 14 is a piston with the axle 16 of the vertical direction of support 21, when the air pressure in the long cylinder 14 changes, long cylinder 14 will move along axle 16, and pedestal 15 connects long cylinder 14, the cylinder 11 of losing heart, piston rod 13 and the pump housing 10 simultaneously, therefore, by regulating the air pressure in the long cylinder 14, can regulate the position of the pedestal 15 of shield tail grease pump with the top in the vertical direction.If shield tail grease pump is placed in the grease tank, can regulate the air pressure of long cylinder 14, so that pedestal 15 just in time is on the pasta of grease tank, and along with the decline of pasta, pedestal 15 descends thereupon.
The switching of the pump housing 10 between oil extraction and oil suction can realize by a selector valve 8 is set, and selector valve 8 cylinder 11 of losing heart relatively fixedly installs, and a upper stroke switch 9 and a lower stroke switch 10 ' are set on the selector valve 8, and selector valve 8 for example is a two-position three-way valve.One collision block 130 is set on piston rod 13, collision block 130 can rush open upper stroke switch 9 and lower stroke switch 10 ' in the moving process of piston 13, in the present embodiment, when piston rod 13 moves up, collision block 130 strikes after the upper stroke switch 9, and the cylinder 11 of losing heart just begins piston rod 13 and moves down, and when piston rod 13 moves down, collision block 130 strikes lower stroke switch 10 ' afterwards, and the cylinder 11 of losing heart just begins piston rod 13 and moves up.And piston rod 13 moves down in the process, closes in the one-way valve (not shown) of the filler opening setting of the pump housing 10, and opens the pump housing 10 beginning oil extractions in the one-way valve (not shown) of the oil outlet setting of the pump housing.And piston rod 13 moves up in the process, opens in the one-way valve (not shown) of the filler opening setting of the pump housing 10, and closes the pump housing 10 beginning oil suctions in the one-way valve (not shown) of the oil outlet setting of the pump housing.
