Abstract

The utility model relates to a water spraying piston pump, which is characterized in that a water outlet pipe (10) is hinged with a one-way valve (11); one end of an elastic water storage air bag (13) is connected to the water outlet pipe, and the other end of the elastic water storage air bag (13) is connected with a pipe joint (12); a piston in a cylinder body (5) is composed of a piston rod (4), a fixedly connected clamping plate (16) and a freely sheathed clamping plate (15); a connecting rod (1) is hinged with the piston rod (4); a sealing ring (14) is clamped between the two clamping plates; a guide plate (17) is fixedly connected to the piston rod. Water pumped by the utility model can be stored in the elastic water storage air bag and has definite pressure, which causes the water to continuously jet and irrigate and replenish new water to the air bag simultaneously and continuously. The utility model has the advantages of convenient use and low cost; in addition, because the piston adopts the structure that the sealing ring is clamped between the upper and the lower clamping plates and because of the structure of the guide plate, the utility model has the advantage of compact structure.

Description

The water spray reciprocating pump

Technical field:

The utility model relates to the water pump in a kind of mechanical engineering field, particularly a kind of water spray reciprocating pump from underground water intaking.

Background technique:

Common water pump has been widely used in All aspects of as the power equipment of water intaking, but there is price height, heaviness, carrying and installation inconvenience, and be subjected to the restriction of power supply and water-supply method, as single user, the underground water intaking of the little water yield, irrigation canals and ditches water intaking, irrigation work in the rural area, common water pump just uses very trouble, even can't use.Common pumped well then can only be off and on from underground water intaking, and its water withdrawal is little, do not have pressure, and therefore no waterpower lift can't directly carry out the irrigation work in farmland.Extensively retrieve at the problems referred to above, still find no solution related to the present invention.

Summary of the invention:

The purpose of this utility model be exactly design in order to solve the above-mentioned defective that exists in the prior art a kind of have lift, can spray irrigation reciprocating pump.

To achieve these goals, the utility model has adopted following technological scheme:

A kind of water spray reciprocating pump, it comprises a cylinder body and the intake pipe and the outlet pipe that link to each other, water inlet pipe mouth is provided with an one-way valve, be provided with the piston that matches in the cylinder body, a hinged connecting rod on the piston, it is hinged with the crank that is hinged on the cylinder body, it is characterized in that the hinged one-way valve of effluent pipe mouth, in elasticity water storage air bag of connection is included in this one-way valve on the outlet pipe, elasticity water storage air bag the other end connecting tube joint.Described piston is made up of the clamping plate of a piston rod and affixed clamping plate and an empty cover, connecting rod and piston rod one end are hinged, accompany seal ring between two clamping plate, the nut that the piston rod the other end is provided with screw thread and links to each other, nut cooperate with the empty clamping plate that overlap seal ring are fixedly clamped.An affixed guide plate on the described piston rod is beneficial to moving of piston.

Because the utility model has adopted one-way valve and elasticity water storage air bag has been set at the outlet pipe place, the water that makes the utility model extract out can be stored in the elasticity water storage air bag and have certain pressure, can make water carry out continuous injection by pipe joint control, continue in elasticity water storage air bag, to replenish new water continuously by pressing crank simultaneously, so it has advantage easy to use, with low cost, that have wide range of applications.In addition, piston adopt to be gone up die holder and is clipped seal ring, and the structure of guide plate, makes to the utlity model has compact structure, advantage that efficient is high.

For the utility model is described in further detail, following accompanying drawing provides a most preferred embodiment of the present utility model.

Description of drawings:

Fig. 1 is a plan view of the present utility model, and piston is in the state that draws water that rises;

Fig. 2 is that piston of the present utility model is in decline setting-out state, and elasticity water storage air bag is in the expansion water stored state simultaneously;

Embodiment:

As shown in Figure 1, basic structure of the present utility model comprises cylinder body 5 and is coupled to intake pipe 9 below it, be provided with a T type one-way valve 7 in the water inlet of cylinder body 3, its valve rod 8 inserts in the intake pipe, support of welding on the outer wall of cylinder body 5, a hinged crank 2 on it, the hinged connecting rod 1 of an end of crank 2.Inventive point of the present utility model is: 1, piston is made up of piston rod 4 and affixed thereon clamping plate 16, the clamping plate 15 that are placed on it, clip seal ring 14 between two clamping plate, the lower end of piston rod 4 is shaped on screw thread, with nut 6 clamping plate 15,16 and seal ring 14 wherein is connected and fixed; The affixed guide plate 17 in the upper end of piston rod 4, the stuck or excessive wear of unlikely skew when moving up and down in order to the protection piston; Connect a connecting plate 3 in the upper end of piston rod 4, it and connecting rod 1 are hinged.2, the hinged one-way valve 11 in the end of outlet pipe 10, the neck of outlet pipe 10 connects an elasticity water storage air bag 13, and in it was included in one-way valve 11, the other end of elasticity water storage air bag connected in pipe joint 12.

Working procedure of the present utility model is as follows: as shown in Figure 1, press down crank 2, drive piston by connecting rod 1 and move up, the water in the intake pipe 9 is washed one-way valve 7 open and is entered in the cylinder body 5; After piston moves to peak, on carry crank 2, press down piston by connecting rod 1, this moment, one-way valve 7 was closed, and one-way valve 11 is washed open, water enters in the elasticity water storage air bag 13.After storing more water in the elasticity water storage air bag, can open pipe joint 12 and carry out spray irrigation, press moisturizing continuously in 2 pairs of air bags of crank simultaneously continuously, can carry out continuous spray irrigation work.
