Description

A kind of underground injection showerhead

[technical field]

The utility model relates to tobacco plant protection field, especially relates to a kind of underground injection showerhead for the underground damage by disease and insect of vega is prevented and treated.

[background technology]

Known plantation tobacco is in order to gather in the crops tobacco leaf, but all can affect output and the quality of tobacco leaf due to underground damage by disease and insect, so for the output that better increases tobacco leaf and the quality that improves tobacco leaf, to the extermination of disease and insect pest of tobacco, particularly be hidden in the underground pests control and just seem particularly important; At present, be exactly sprayer for the most important apparatus of administering tobacco disease insect pest use, though it has played certain protective effect in tobacco planting, but because mister head only can spray medicine or fertilising to upper surface or the earth's surface of tobacco leaf, and the whole plant height degree of tobacco of plantation is shorter, so existing sprayer is difficult to prevent and treat for being hidden in underground damage by disease and insect etc., namely can only rely on manual operation to prevent and treat for underground damage by disease and insect, this normally adopts the method for excavated by manual work hole irrigation root; But this method not only labour intensity is large, time-consuming taking a lot of work, and wayward dose, also often cause control untimely because being short of hands, underground damage by disease and insect large tracts of land is infected, and then cause yield of tobacco and Quality Down, and also can cause the in poor harvest or total crop failure of the large tracts of land of vega when serious, brought imponderable economic loss to the tobacco grower.

[summary of the invention]

In order to overcome the deficiency in background technology, the utility model discloses a kind of underground injection showerhead, described shower nozzle can be prevented and treated and apply fertilizer by underground injection underground damage by disease and insect, reach the output of raising tobacco leaf and the effect of quality, and saved greatly manpower, alleviated tobacco growers' labour intensity.

For achieving the above object, the utility model adopts following technical scheme:

A kind of underground injection showerhead, described shower nozzle comprise sleeve pipe, tube connector, shank, silk fluid cushion and taper needle point; The mouth of pipe of described sleeve pipe one end fixedly is communicated with the end mouth of pipe of internal diameter greater than the tube connector of sleeve pipe external diameter, and the other end of sleeve pipe is provided with a fluid hole at least near the tube wall of end; The inwall of the described tube connector other end mouth of pipe is provided with the screw thread that is connected for spraying rod for sprayer; Described shank diameter is less than casing inner diameter, and an end of shank is connected with a fluid cushion, and the other end of shank is connected with the taper needle point; Described silk fluid cushion be positioned at tube connector and the mouth of pipe of Sealed casing pipe corresponding end fully after shank is connected; The diameter at the described taper needle point cone end is greater than casing diameter and the mouth of pipe of Sealed casing pipe corresponding end fully; Can be in the body of sleeve pipe after shank connecting filament fluid cushion and taper needle point twitch arbitrarily, and silk fluid cushion and taper needle point can not contact the mouth of pipe of sleeve pipe respective end simultaneously.

Described underground injection showerhead, described sleeve pipe and tube connector are made as integrative-structure or are connected together by the screw thread silk.

Described underground injection showerhead, described sleeve pipe tube wall are provided with two uniform fluid holes at least.

Described underground injection showerhead, described shank is made as integrative-structure with a silk fluid cushion, and shank and taper needle point are connected together by the screw thread silk.

Described underground injection showerhead, described shank and taper needle point are made as integrative-structure, and shank and the silk fluid cushion be connected together by the screw thread silk.

Owing to adopting technical scheme as above, the utlity model has following beneficial effect:

Underground injection showerhead described in the utility model can be easy the soil of the insertion tobacco root that need to prevent and treat or apply fertilizer, then inject corresponding liquid or fertilizer, thereby effectively carried out the control operation of underground damage by disease and insect or fertilising operation targetedly, and then provide solid guarantee for output and the quality that improves tobacco leaf; Use described underground injection showerhead not only can effectively reduce the operating time, and can also save a large amount of manpowers.

In figure: 1, sleeve pipe; 2, tube connector; 3, shank; 4, silk fluid cushion; 5, fluid hole; 6, taper needle point.

[embodiment]

Can explain in more detail the utility model by the following examples, open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope, and the utility model is not limited to the following examples;

In conjunction with the described underground injection showerhead of Fig. 1, described shower nozzle comprises sleeve pipe 1, tube connector 2, shank 3, silk fluid cushion 4 and taper needle point 6; The mouth of pipe of described sleeve pipe 1 one ends fixedly is communicated with the end mouth of pipe of internal diameter greater than the tube connector 2 of sleeve pipe 1 external diameter, as required, sleeve pipe 1 and tube connector 2 can be made as integrative-structure or both are connected together by corresponding screw thread silk; Simultaneously, the other end of sleeve pipe 1 is provided with a fluid hole 5 that is used for flowing out liquid or solution at least near the tube wall of end, more unobstructed for liquid or solution are flowed out, two uniform fluid holes 5 can be set at least at the tube wall of sleeve pipe 1, namely plural fluid hole 5 is made as equidistantly each other; The inwall of described tube connector 2 other end mouths of pipe is provided with the screw thread that is connected for spraying rod for sprayer, namely be convenient to described underground injection showerhead and spraying rod for sprayer are linked together, it should be noted that, described tube connector 2 is wanted to satisfy the needs of a fluid cushion 4 actions in tube connector 2 interior remaining space after being fastenedly connected with spraying rod for sprayer;

Described shank 3 diameters are less than sleeve pipe 1 internal diameter, and an end of shank 3 is connected with a fluid cushion 4, and the other end of shank 3 is connected with taper needle point 6; Assemble described shower nozzle for being more convenient for, shank 3 and silk fluid cushion 4 can be made as integrative-structure, then utilize corresponding screw thread that
