Description

Crops root liquid syringe

The utility model is an agricultural equipment.Especially a kind of to the crop root part injecting fluid syringe of (comprising water, liquid fertilizer, liquid medicine etc.).

Spring drought, crop root part disease, insect pest, fertilizer deficiency etc. are the major obstacles of crop growth.Though the annual investment in agriculture of China increases year by year, and mobilizes the peasant to build water conservancy projects.But because China soil is vast, the physical features complexity, the chemical fertilizer shortage, problems such as agricultural chemicals deficiency can not be resolved in a short time.

The utility model purpose is, family-contract responsibility system of generally carrying out according to the present rural area of China and the characteristics of having a large population and a few land provide a kind of and chase after water, topdress, chase after the crop root part fluid injector of medicine to crop root part.

The utility model technical solution: a liquid control room is set between injection-tube and needle body, and the structure of this chamber is: the liquid outside the control room is injected into crop root part through indoor admission chamber, the needle body that goes out sap cavity and chamber bottom.Simultaneously, stop foreign material around the needle body (as silt etc.) to enter in the needle body.This chamber concrete structure is: there is a liquid isolation strip at the position therebetween, and this band is divided into this chamber admission chamber and goes out sap cavity.Into and out of the lower end of sap cavity respectively with locular wall on inlet, chamber at the bottom of on needle body be communicated with; Upper end into and out of sap cavity all is communicated with injection-tube.Lower port at admission chamber is provided with a liquid inlet and outlet valve by this mouthful of spring pressing respectively with the upper port that goes out sap cavity.When piston along the injection tube wall when moving up, the feed liquor valve of admission chamber lower end is opened inlet, liquid mouthful enters in the injection-tube thus.Simultaneously, the liquid valve that goes out the sap cavity upper port is this mouthful pressing, goes out that no liquid flows in the sap cavity; When the promotion hand pressure handle moved down piston, the feed liquor valve closure inlet in the admission chamber, the liquid in the admission chamber did not flow.At this moment, go out valve body in the sap cavity under the effect of pressure, with mouthful opening of sealing originally, the liquid in the injection-tube flows in the needle body through the lower port in this mouthful and this chamber, and is injected in the crop root part soil by two rounds on the needle body.

The utility model advantage:

1, this instrument can directly be injected into crop root to water, liquid fertilizer, liquid medicine, reaches certain depth and range, and the whole root system of radiation is not hindered root, do not destroyed soil layer; Water saving, fertile, the joint medicine of joint, in good time, instant effect.

2, this instrument is small, and is flexible and convenient to use.It both had been applicable to the one man operation of single household, was applicable to the production operation in large area of many people joint operation again.

3, applied range.The utility model instrument is applicable to that the drought resisting of crops such as the corn, jowar, sunflower, beet, potato (potato), watermelon, Chinese cabbage, radish of hole kind chases after water, topdresses, chases after medicine.But drilling crops such as paddy gruel, soya bean are also had certain applied value, and needing only increases some notes density, also can reach to impose purpose.

Below in conjunction with description of drawings the utility model most preferred embodiment.

Accompanying drawing is the utility model structural representation.

In the accompanying drawings, 1 hand pressure handle, 2 piston rods, 3 limit sliding chutes, 4 gag lever posts, 5 portable handles, 6 upper tube caps, 7 injection-tubes, 8 are quantitatively sold, 9 pipe joints, 10 pipe clamps, 11 pistons, 12 closed-loops, 13 feed tubes, 14 switches, 15 infusion ports, 16 cavity isolation strip, 17 liquid pumping holes, 18 fluid charged chambers, 19 go out sap cavity, 20 springs, 21 liquid valves, 22 liquid outlets, 23 admission chambers, 24 feed liquor valves, 25 inlets, 26 solid needle stands, 27 needle bodies, 28 pin holes, 29 awl caps.

In the accompanying drawings, cavity isolation strip 16 is I-shaped; A limit sliding chutes 3 is arranged on the piston rod 2, and a gag lever post corresponding with this groove 4 is arranged on upper tube cap 6; Around the needle body 27 two rows pin hole 28 is arranged, and needle body 27 front ends are taper awl cap 29.

In conjunction with above-mentioned accompanying drawing in detail the course of work is described in detail:

1, when when having handed up hand pressure handle 1, feed liquor valve 24 is opened inlet 25, and the liquid (water, liquid fertilizer, agricultural chemicals water etc.) in the feed tube 13 flow in the admission chambers 23 along inlet 25, and under the pressure outside effect, in liquid pumping hole 17 enters injection-tube 7 cavitys; Simultaneously, go out liquid valve 21 in the sap cavity 19 under the draft effect,, go out that no liquid flow in the sap cavity 19 infusion port 15 pressings.

2, when pressing hand pressure handle 1 downwards with hand, liquid in the injection-tube 7 has a downward pressure to fluid charged chamber 18, the liquid valve 21 that this pressure will go out in the sap cavity 19 is simultaneously depressed, liquid in pipe and enters coupled needle body 27 and is injected into crop root part by the pin hole on it 28 along liquid outlet 22 in infusion port 15 flows into out sap cavity 19.

Claims (4)

1, a kind of crop root part fluid injector that comprises body, push rod, piston, injection-tube is characterized in that the fluid charged chamber 18 between injection-tube 7 and the needle body 27:
