Abstract
The utility model discloses a multi-pump crank case for an electric butter filling machine, relating to the technical field of electric butter filling machines. The multi-pump crank case comprises a crank case body, more than two plunger pumps, a check valve, a multi-way valve and an eccentric mechanism, wherein the tail end of the plunger rod of the plunger pump props against the outer circumference of a large bearing of the eccentric mechanism by virtue of the action of a reset spring. Due to the adoption of the structure, compared with the prior art, the multi-pump crank case has the advantages of being high in butter output pressure, slight in friction among parts, low in fault rate and long in service life.
Description
Technical field
The utility model relates to the electric grease injecting machine technical field, particularly relates to a kind of crankcase that is used for electric grease injecting machine.
Background technique
Chinese invention patent CN101718388A discloses a kind of electric grease injecting machine, its by reducer shaft, eccentric disc, live axle, slide block, piston, cylinder body, motion block, dial oily sheet, oil pressing plate, decide piece, base plate, contiguous block, spiral forced oil device live axle, bearing, outward flange, inner flange, oil inlet hole, oil drum, piston hole, groove, oil outlet, square hole, the oily sheet of pressure form.The crankcase of this electric grease injecting machine has adopted traditional off-centre directly moving to song, causes exporting that butter pressure is lower than phase mutual friction between 40MPa, the parts, noise is high, rate of fault is high, working life is short.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes existing technology, provides that a kind of rate of fault is low, long service life, the crankcase that is used for electric grease injecting machine that noise is low.
The utility model is used for many pump housings crankcase of electric grease injecting machine; Comprise crankcase body; Plural plunger pump is evenly being arranged in the outside at crankcase; The oil outlet of said each plunger pump all is connected on the multiple-way valve through one-way valve, oil pipe, and the oil outlet of said multiple-way valve is connected with high-voltage tube through oil pipe; Said crankcase inside is provided with eccentric stiffener; Said eccentric stiffener by transmission shaft, the big bearing that is connected with eccentric bushing interference on being arranged on transmission shaft, be arranged on two bearings that are distributed in said big bearing both sides on the transmission shaft and form; One on said two bearings are fixedly connected with at the bottom of the crankcase case, and another is fixedly connected with the crankcase case lid; The plunger rod of said plunger pump relies on action of reset spring, and the end of plunger rod is withstood on the excircle of the big bearing of said eccentric stiffener.
The transmission shaft lower end of the inner eccentric stiffener of said crankcase is connected with the hinge wheel that is arranged on bottom, fuel tank chassis, and said hinge wheel is connected with the minor sprocket of motor output shaft end through chain.
The one-way valve that between said each plunger pump and multiple-way valve, is provided with is the one-way valve more than the two-stage.
The utility model is owing to adopt above structure, has compared with prior art that output butter pressure is high, friction is slight between the parts, rate of fault is low, the advantage of long service life.
Description of drawings
Fig. 1 is used for the structural representation of many pump housings crankcase of electric grease injecting machine for the utility model;
Fig. 2 is the plan view of many pump housings crankcase shown in Figure 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated, but the protection domain of the utility model is not only for so.
As shown in Figure 1, among the figure: 1, level Four individual event valve, 2, the pump housing, 3, plunger rod, 4, capacity eccentric bearing; 5, transmission shaft, 6, eccentric bushing, 7, crankcase cover, 8, hinge wheel; 9, base, 10, oil outlet tube, 11, filler opening, 12, dial oiled-plate method; 13, crankcase, 14, bearing, 15, bearing support, 16, multiple-way valve.
It comprises crankcase body, is evenly arranging six plunger pumps in the outside of crankcase, and the oil outlet of each plunger pump all is connected on the multiple-way valve through level Four one-way valve, oil pipe, and the oil outlet of multiple-way valve is connected with high-voltage tube through oil pipe; Crankcase inside is provided with eccentric stiffener; Eccentric stiffener by transmission shaft, the big bearing that is connected with eccentric bushing interference on being arranged on transmission shaft, be arranged on two bearings that are distributed in big bearing both sides on the transmission shaft and form; One on two bearings are fixedly connected with at the bottom of the crankcase case, and another is fixedly connected with the crankcase case lid; The plunger rod of plunger pump relies on action of reset spring, and the end of plunger rod is withstood on the excircle of the big bearing of said eccentric stiffener; The transmission shaft lower end of the inner eccentric stiffener of crankcase is connected with the hinge wheel that is arranged on bottom, fuel tank chassis, and hinge wheel is connected with the minor sprocket of motor output shaft end through chain.
The inner eccentric stiffener of crankcase is that the deflection cover is fixed on the transmission shaft, and the big bearing of eccentric stiffener is connected with the interference of deflection cover, and two bearings is arranged on the both sides of big bearing on the transmission shaft in addition, and eccentric stiffener integral body is bumped into crankcase.
The utility model working principle is following; The plunger rod of each plunger pump of rotation driving of eccentric stiffener is done straight reciprocating motion (backhaul has brute spring to automatically reset) and is driven the oil mixing board rotation above the crankcase simultaneously; The oil mixing board end is lower than crankcase, just in time gets into groove, and the You of the Jin by force order sheet of band gradient is housed; Butter directly is pressed in the filler opening, oil is released.
