Abstract

The utility model discloses a reducing back-stop hydraulic pumping device, comprising a piston, a piston barrel, a piston rod, and a support rack. The end head of the piston barrel is provided with an upper check valve and a lower check valve which are communicated with the piston barrel. The piston rod is provided with an upper slide shaft and a connector which is connected with a power device, and the piston barrel is arranged on the support rack. The upper check valve is communicated with the a high position tank through a pipe, and the lower check valve is communicated with a lower position tank through the pipe. The liquid in the lower position tank can be continuously sucked into the high position tank through waggling a rocker bar by the labor or the machine. The small flexible utility model which has the advantages of simple operation, convenient conveying, high work efficiency, compact structure, and lower cost is suitable for the use of farmers in widely poor area.

Description

Reducing back-stop hydraulic pumping device

Technical field the utility model belongs to a kind of diameter reducing type back-stop hydraulic pumping device.

The existing liquid pumping device of background technique, though higher as efficient such as various water pumps, also very laborsaving, consume a large amount of electric power, buying a water pump neither a nothing the matter for the peasant of a common peasant household, particularly poverty-stricken area.Therefore, in vast poverty-stricken area, peasants still by manpower the liquid load are carried on the back eminence or at a distance, it is time-consuming to require great effort, inefficiency.

The summary of the invention the purpose of this utility model be propose a kind ofly laborsavingly to save time, efficient height, low cost of manufacture, manpower and all spendable reducing back-stop hydraulic of other power pumping device are to solve the deficiencies in the prior art.

This reducing back-stop hydraulic pumping device that the utility model proposes, it has piston, piston cylinder, piston rod and support, it is characterized in that having on the piston cylinder a last check valve and following check valve to be communicated with cylinder barrel, the joiner that slide-bar is arranged on the piston rod or be connected with power plant, cylinder body is rack-mount.

There is one to go up non-return plug in the last check valve, the tube inlet that raises up, a non-return plug is down arranged in the following check valve, down the suction pipe inlet by following non-return spring retaining cap by last non-return spring retaining cap.

Raising up has a non-return water storage box in labour-saving between pipe and high-order pond.

The piston cylinder of two symmetries is installed on same support, total same piston rod, the piston rod middle part has a slide-bar reciprocating by rack-mount rocking bar push-and-pull.

On same support, can have only a piston/cylinder.

Piston rod can be connected with rocking bar, also can be connected with power engine.

The rocking handle of being convenient to shake is arranged on the rocking bar.

Working procedure of the present utility model is as follows:

Following suction pipe is immersed in the liquid in the next pond, and the pipe that raises up connects a pond.When rocking bar does not move, upper and lower check valve is all cutting out, when rocking bar hauls piston and moves outside cylinder body, negative pressure in the cylinder body is inhaled the following non-return plug of driving down check valve, the liquid in the next pond is inhaled in the cylinder, when rocking bar was pushing away piston towards the motion of opposite direction, the pressure of cylinder body forced down that check valve cuts out, last check valve is opened, and liquid is pressed into high-order pond.When two working cylinders were housed on the same support symmetrically, the work phase place of check valve just differed 180 degree about them, does complementary motion, has so just guaranteed that whole device is continuously to the head-tank lifting liquid.Raise up the pipe and high-order pond between a non-return water storage box is set can be laborsaving.

Characteristics of the present utility model are can manpower to shake pumping liquid, small and exquisite flexible, simple to operate, convenient in carrying, high working efficiency, compact structure, with low cost, and the peasant who is fit to vast poverty-stricken area uses.

Appended drawings 1 is plan view of the present utility model (broken section).

Accompanying drawing 2 is plan views of the present utility model.

Accompanying drawing 3 is left views of the present utility model.

The label of each component is as follows among Fig. 1-3:

1-rocking bar; 2-rocking handle; 3-chute; 4-slide-bar; 5-piston cylinder cover; 6-piston rod; 7-piston; 8-piston cylinder; 9-upward non-return plugs; 10-upward check valves; 11-upward non-return springs; 12-pipe raises up; 13-following suction pipe; 14-following non-return plug; 15-following check valve; 16-following non-return spring; 17-piston cylinder backing ring; 18-rocker; 19-support.

Embodiment now reaches example in conjunction with the accompanying drawings the utility model is further specified: the internal diameter of piston cylinder (8) 4 is 8: 1 with the ratio of pipe (12) internal diameter that raises up, and following suction pipe (13) can be consistent with the pipe that raises up or slightly thick.Being specially the cylinder body inner diameter is 12CM, raise up the pipe and following suction pipe inner diameter be 1.5CM, cylinder body length is 20CM, piston (7) and cylinder body for strengthening commutativity, can add a gum cover for movingly on piston, the one, strengthen sealability, the 2nd, can change after the wearing and tearing, piston rod (6) is shared one of two cylinder bodies, length need only guarantee that two complementary piston have the stroke of 15CM to get final product.The cylindrical slide-bar (4) that the piston rod midpoint is established a slip usefulness crosses out both sides, stretches into interior slip of chute (3) of rocking bar, and rocking bar (1) is installed on the support (19) by rocker (18).The people strides and steps on both hands assurance rocking handle (2) waggle on frame during operation, can promote piston rod and move back and forth, and device just can be worked.Being connected between piston cylinder cover (5) and cylinder body is threaded, and is similar to existing pump cylinder cap.The means of fixation on frame of cylinder body is that the backing ring (17) with some semicircles is fixed with cylinder body earlier, and backing ring is fixed with its carriage again.The structure of upper and lower check valve (10,15) is identical, but go up the position opposite that non-return plug (9) and following non-return plug (14) stop up, go up the hardness of non-return spring (11) and following non-return spring (16) and determine that according to experiment too soft obstruction effect may be undesirable, the gas of can requiring great effort very much too firmly.Between check valve and cylinder body, with raise up pipe or being connected to be generally and being threaded between suction pipe down.Above-mentioned parts is made of common iron.

This installation weight is light, and a people can move completely pickaback, and pipe can be with predicting flexible pipe, and field, the Xiao Yuan of family are available everywhere, simple to operate, at first sight can, make easily, low price, peasant household on probation is liked very much.
