Abstract

The utility model discloses a telescopic spray head body, which belongs to a fixing device of the spray head. The utility model is composed of a three-way pipe 1. The utility model is characterized in that a slip pipe 7 with a sealing ring 5 and an outer capped edge 6, a self-closing stop valve 10 inside the slip pipe and a dust cap 12 of a closed slip pipe are arranged at the inner side of the three-way pipe; an inner capped edge 3, a dust ring 4 and a clamping cap 2 are arranged at the upper end of a vertical pipe of the three-way pipe. The utility model has the advantages that the spray head body is telescopic and the mechanized cultivation, seeding, and reaping are not influenced.

Description

Flexible sprayer body

The utility model relates to a kind of device that shower nozzle is installed, and a kind of flexible sprayer body of saying so more specifically is mainly used in agricultural sprinkling irrigation industry.

The existing used shower nozzle of field irrigation is all fixed, and mainly is the not flexible of sprayer body that shower nozzle is installed.Plough, when sowing, harvesting, agricultural machinery can't normal operation, has both reduced operating efficiency, need again artificial dispose shower nozzle and around soil in the certain limit, otherwise can cause the waste in soil.

The purpose of this utility model provides and a kind ofly can be hidden in undergroundly, can stretch out the face of land again, the flexible sprayer body that shower nozzle is installed on it.

The purpose of this utility model reaches by the following technical programs: this flexible sprayer body, form by three-way pipe, its special character is, on the vertical tube connector of this three-way pipe, at least be provided with a slip pipe, the lower end of each slip pipe is provided with outer rib, establish groove on the circumference of rib outside, groove is embedded with sealing ring, is provided with inner retaining side on the top of the most inboard slip pipe, can move up and down along this inner retaining side centre bore, and leave the Self closing valve of delivery port and the dust cap of this slip pipe upper port of sealing on its sidewall, be equipped with inner retaining side at the three-way pipe and the non-port of export of inboard slip pipe, be positioned at the dust ring and the fixing friction top of dust ring on the inner retaining side outer face.Here, the meaning that is provided with a slip pipe on the vertical tube connector of three-way pipe at least is meant that slip pipe can be 1,2,3 ... N.This can decide as required, and generally speaking, slip pipe just can reach requirement at 3 with interior.

Slip pipe is 1, the most inboard slip pipe at this moment, and the most inboard non-slip pipe is exactly same slip pipe.

Slip pipe is 2, and at this moment the most inboard slip pipe is the 1st slip pipe, and the most inboard non-slip pipe is the 2nd slip pipe.

Because the utility model has adopted above-mentioned technical solution, makes it compared with prior art, having sprayer body can stretch, and can contract again, thereby make when spraying, and sprayer body stretches out the face of land, installs nozzle and exercises spraying function; Plough, when sowing, harvesting, the retraction of shower nozzle physical efficiency is underground, thereby makes the full wafer soil agricultural mechanical operation that can suit, and increases work efficiency and puts in order ground, sowing, harvesting quality.

The explanation of accompanying drawing drawing:

The structural representation of an embodiment of Fig. 1-the utility model;

The structural representation of second embodiment of Fig. 2-the utility model.

Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.

Embodiment 1, with reference to figure 1.This is the flexible sprayer body of a single slip pipe, in the vertical tube end of three-way pipe 1 inner retaining side 3 is arranged, dust ring 4 that touches mutually with inner retaining side 3 outer ends and the friction top 2 that is threaded with inner retaining side 3 and touches mutually with dust ring 4.Slip pipe 7 is positioned at the vertical tube of three-way pipe, on the outer rib 6 of its lower end groove is arranged, and groove is embedded with sealing ring 5, and an inner retaining side 8 is arranged at its top, and the circumferential wall of this inner retaining side centre bore is touched mutually with Self closing valve 10.Self closing valve 10 covers the hollow cylindrical of rib for being with lower seal, is with spring 9 on its post jamb, has 4 water inlets 11 on the post jamb near capping down.The last flange belts center delivery port of Self closing valve 10.The top of slip pipe 7 is threaded with dust cap 12.Use is, the horizontal connection tube of the flexible same axis of sprayer body is connected with main water supply pipe, give downward pressure of dust cap, slip pipe 7 in the vertical tube of three-way pipe to lower slider, block until the compacted lid 2 of dust cap lower limb, dust ring 4, at this moment slip pipe 7 has been reduced in the vertical tube of three-way pipe, and its dust cap is positioned at underground certain depth, does not influence mechanization and ploughs, sows, gathers in.When need are sprayed, start supply-water pump, water supply enters flexible sprayer body through main water pipeline, push away Self closing valve 10 on the hydraulic pressure, Self closing valve 10 covers sliding pipe 7 by lower seal, slip pipe 7 upwards slides along the vertical tube of three-way pipe, touches mutually with inner retaining side 3 on the three-way pipe vertical tube until rib 6 down, at this moment the part of dust cap 12 and slip pipe 7 certain distance that bassets.Unload dust cap 12, the shower nozzle to be connect of screwing on waits that the lower end that connects shower nozzle presses down Self closing valve 10, spring 9 is by the last rib compression of Self closing valve 10, and Self closing valve 10 moves down, and water inlet 11 communicates with the water channel of slip pipe, water enters shower nozzle through the upper water-out mouth of water inlet 11 and Self closing valve 10, sprays through shower nozzle.Because should flexible sprayer body be single slip pipe, the length of this list slip pipe and three-way pipe vertical tube be longer, it is darker that water supply trunk line and flexible sprayer body need bury, and hard for soil property, the bottom is the area of stone, buries difficulty underground.

Embodiment 2, and with reference to figure 2, this is the flexible sprayer body of the two slip pipes of band.Compare with embodiment 1, increased slip pipe 16, this slip pipe is between the vertical tube of slip pipe 7 and three-way pipe, and promptly slip pipe 16 is placed in the three-way pipe vertical tube, and slip pipe 7 is placed in the slip pipe 16.Compare with embodiment 1, in not changing slip pipe 7, under the prerequisite of external diameter, need to increase the interior external diameter of three-way pipe vertical tube.Because slip pipe 16 and three-way pipe vertical tube bottom synapsis mutually need prevent that sealing enters, so be embedded with sealing ring 18 at the groove of the outer rib 17 of slip pipe 16; Space because of upper end between slip pipe 16 and the slip pipe 7 need prevent that dust from entering again, and prevents that slip pipe 7 from skidding off, so be provided with inner retaining side 14, dust ring 13 and friction top 15 in the upper end of slip pipe 16.Because slip pipe is two, under the identical condition of the flexible sprayer body of extension elongation and single slip pipe, the length of three-way pipe vertical tube, the contraction in length of slip pipe 7 near half, use in the area that soil layer preferably is more shallow, and it is also desirable to use this flexible sprayer body in dark soil layer area.More shallow because of the irrigation water supply pipe laying can reduce workload.The use of being somebody's turn to do flexible sprayer body is substantially the same manner as Example 1.When retraction was underground, sleeve pipe 7 was reduced to earlier in the sleeve pipe 16, and sleeve pipe 16 is again in the vertical tube of retraction three-way pipe then.When stretching out, hydraulic pressure is earlier to pushing sleeve pipe 16, and pushing sleeve pipe 7 on Self closing valve 10 touches with the inner retaining side 14 of sleeve pipe 16 mutually until being stretched over 7 times ribs 6 of sleeve pipe then, and the following rib 17 of sleeve pipe 16 touches mutually with the inner retaining side 3 of three-way pipe vertical tube.

In like manner, can also provide slip pipe is 3,4 ... N flexible sprayer body.
