Abstract
The utility model relates to a double-pipe atomizer piston pump which generally comprises a pump, an air chamber barrel, a piston rod device, a check valve and a fixed panel. The check valve is arranged at the bottom of the pump, the inside of the pump is communicated with the inside of the air chamber barrel; the pump and the air chamber barrel are connected into a whole through a reinforcing bar; the lower part of the piston rod device is contained in the pump; the piston rod device is fixed on the fixed panel through a fixer; the upper part of the piston rod device is connected with the power mechanism of the atomizer; the fixed panel is also fixed with a water outlet pipe which is integrated with the fixed panel; the upper part of the fixed panel is also provided with a connection joint to be communicated with the water outlet pipe; and when the air chamber barrel is fixedly connected with the fixed panel, the water outlet pipe extends to the inside of the air chamber barrel and the connection joint is communicated with the atomizer through a connector. The utility model has simple structure and reasonable design and can well solve the problem of liquid leakage existing in prior atomizer piston pumps.
Description
Technical field
The utility model relates to a kind of field of agricultural machinery, specifically is a kind of reciprocating pump of double hose sprayer.
Background technique
The double hose piston pump of sprayer generally comprises pump at present, the air chamber tube, piston lever arrangement, one-way valve, parts such as fixed panel and outlet pipe, piston lever arrangement and one-way valve are arranged in the pump, the piston rod of piston lever arrangement also is connected with the power mechanism of sprayer, pump inside and air chamber tube inside communicate, pump and air chamber tube all are fixed on the fixed panel, outlet pipe spins by nut and is fixed on air chamber tube and the fixed panel, air chamber tube inside is stretched in the bottom of outlet pipe, the water outlet of outlet pipe is connected with the hydrojet atomising device of outside, the piston pump of sprayer technology maturation of this double hose, operate light, imbibition efficient height, but also there is the joint of outlet pipe and air chamber tube and fixed plate because pressure is higher or loosening, cracking leaks air or the phenomenon of leakage easily.
The model utility content
The purpose of this utility model is to provide a kind of outlet pipe and fixed panel and pump and the whole double hose piston pump of sprayer that is provided with of air chamber tube, the concrete connection reliably, gas leakage or leakage problem can not take place.
The utility model is achieved in that
A kind of double hose piston pump of sprayer generally comprises pump, the air chamber tube, piston lever arrangement, one-way valve and fixed panel, one-way valve is arranged on the bottom of pump, pump inside and air chamber tube inside communicate, it is characterized in that: the piston lever arrangement bottom be placed in pump in, piston lever arrangement is limited on the fixed panel by fixed block, the top of piston lever arrangement is connected with the power mechanism of sprayer, on described fixed panel, also be provided with an outlet pipe, this outlet pipe is shaped with fixing solid slab integral, a connection interface that communicates with outlet pipe also is set on fixed panel top, when the air chamber tube is connected on the fixed panel, outlet pipe stretches to air chamber tube inside, and described connection interface is connected with the hydrojet atomising device by a connection piece.
Connect in aggregates by being connected stiffening rib between described pump and the air chamber tube.
The existing relatively double hose spraying of the utility model spray reciprocating pump is provided with one with the outlet pipe and the fixed panel of original split, certain change takes place in air chamber tube and fixed panel means of fixation like this, originally the air chamber tube passes the fixed hole of fixed panel, by nut phase air chamber tube is fixed on the fixed panel again, this nut is fixedly also being consolidated the chamber fixed panel with outlet pipe in the air chamber tube together, and being the direct hot weld of air chamber tube, means of fixation of the present utility model is bonded on the fixed panel, outlet pipe and solid chamber panel are an integral body, sealing is very good between air chamber tube and fixed panel and the outlet pipe, can not go out leakage or gas leak phenomenon; The utility model air chamber tube and pump also adopt and are wholely set in addition, connect by connecting strong muscle between pump and the air chamber tube, therefore at piston rod during to pump and the pressurization of air chamber tube, air chamber tube and pump do not exist yet because the phenomenon of leakage that sealing problem occurs has improved the reliability of reciprocating pump work.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a perspective exploded view of the present utility model.
Embodiment
As Fig. 1, shown in 2, a kind of double hose piston pump of sprayer generally comprises pump 1, air chamber tube 2, piston lever arrangement 3, one-way valve and fixed panel 4, one-way valve is arranged on the bottom of pump 1, pump 1 inside and air chamber tube 2 inside communicate, connect in aggregates by being connected stiffening rib 5 between described pump 1 and the air chamber tube 2, piston lever arrangement 3 bottoms be placed in pump 1 in, piston lever arrangement 3 is limited on the fixed panel 4 by fixed block 6, the top of piston lever arrangement 3 is connected with the power mechanism of sprayer, on described fixed panel 4, also be provided with an outlet pipe 7, this outlet pipe 7 and fixing solid plate 4 unitary mouldings, a connection interface 8 that communicates with outlet pipe 7 also is set on fixed panel 4 tops, when air chamber tube 2 is connected on the fixed panel 4, outlet pipe 7 stretches to air chamber tube 2 inside, and described connection interface 8 is connected with the hydrojet atomising device by a connection piece 9.
The utility model is wholely set fixed panel 4 and outlet pipe 7, pump 1 and air chamber tube 2 also are wholely set simultaneously, be connected between air chamber tube 2 and the fixed panel 4 is to adopt hot weld bonding, the sticking full Placement of this integrated type setting and hot weld is connected with respect to present spinning and the mode that adopts sealing gasket to seal connects more reliably, can not leak air or the phenomenon of leakage; Simultaneously all-in-one-piece more convenient when assembling is set; Another characteristics of the utility model are that pump 1 is not connected with fixed panel, and just piston lever arrangement 3 is limited on the fixed panel 4, the volume of pump 1 can be done lessly like this, economical with materials and do not influence using effect, and disassembly, cleaning simultaneously or maintenance are also more convenient.
Claims (2)
1, a kind of double hose piston pump of sprayer generally comprises pump, the air chamber tube, piston lever arrangement, one-way valve and fixed panel, one-way valve is arranged on the bottom of pump, pump inside and air chamber tube inside communicate, it is characterized in that: the piston lever arrangement bottom be placed in pump in, piston lever arrangement is limited on the fixed panel by fixed block, the top of piston lever arrangement is connected with the power mechanism of sprayer, on described fixed panel, also be provided with an outlet pipe, this outlet pipe is shaped with fixing solid slab integral, a connection interface that communicates with outlet pipe also is set on fixed panel top, when the air chamber tube is connected on the fixed panel, outlet pipe stretches to air chamber tube inside, and described connection interface is connected with the hydrojet atomising device by a connection piece.
