Example 1

Please refer to Fig. 1, this embodiment provides a two-way retractable spraying rod, which includes: the main body of the rod, the main body of the rod includes a fixed tube 1 and two sets of sliding tubes 2, and the sliding tubes 2 are slidably sleeved on the At the two ends of the above-mentioned fixed pipe 1, the above-mentioned sliding pipe 2 includes a plurality of nozzle monomers 201 which are slidably socketed with each other. A nozzle is opened on the side wall of the monomer 201, and a nozzle 202 is arranged at the nozzle.

In this embodiment, the above-mentioned fixed pipe 1 is a hollow cylindrical pipe, and the above-mentioned sliding pipe 2 is composed of a plurality of cylindrical nozzle units 201 slidingly socketed. Two sets of sliding tubes 2 are respectively slidably arranged at both ends of the above-mentioned fixed tube 1, and can slide and extend to both ends respectively. Wherein, the nozzle units 201 of each group of sliding tubes 2 can also slide to extend or shrink each other, so as to increase or decrease the length of the main body of the medicine rod, which is suitable for spraying effects in different areas. The side wall of each nozzle unit 201 is provided with a nozzle, and a nozzle 202 is arranged at the nozzle. Pesticide liquid is passed into the nozzle unit 201, and the liquid flows out from the nozzle and spreads through the nozzle 202 to increase the coverage area of the liquid. The length of the main body of the medicine rod is adjusted by the telescopic nozzle unit 201, thereby changing the spraying area, increasing the spraying speed, and improving the spraying efficiency. When the area to be sprayed with medicine is large, the sliding tube 2 is extended to increase the spraying area; when the spraying area is small, the sliding tube 2 is contracted to prevent the main body of the medicine rod from being too long and inconvenient to operate. After use, the sliding tube 2 is shrunk to reduce the length of the main body of the medicine rod for easy storage.

When in use, according to the area and shape of the farmland to be sprayed, the sliding nozzle unit 201 adjusts the length of the main body of the medicine rod, and two people hold the sliding pipe 2 from both ends respectively. The medicinal liquid is passed into the nozzle unit 201, and the medicinal liquid diffuses through the nozzle 202. At this time, the staff at both ends only need to move forward slowly to spray the pesticide. When planting crops or dividing the land area, field ridges are often built. When spraying drugs, two workers can directly move and operate on the field ridges to avoid touching the plants and causing the liquid remaining on the plants to contact the skin. Since the sliding tube 2 is retractable, it can better adapt to the spraying operation of farmland with different widths and shapes. When spraying, it only needs to move in one direction, avoiding the operation of swaying the medicine rod left and right in traditional small sprayers, and reducing the splash of atomized medicine liquid , can not only reduce the operator's inhalation or contact with the liquid medicine, but also ensure that more liquid medicine is sprayed on the plants or land, and improve the spraying effect of the pesticide.

It should be noted that, in the drawings of this embodiment, the slide tube 2 shown only includes two nozzle units 201 . In actual production, the number of nozzle units 201 can be increased or decreased as required. The larger the number of individual nozzles 201, the wider the spraying area. The number of individual nozzles 201 can be 3, 4, 5 or 6, and the specific number is not limited.

In this embodiment, the above-mentioned locking assembly 3 is used to fix two nozzle bodies 201 that slide mutually. When the length of the nozzle unit 201 is adjusted to a proper position, it is locked by the locking assembly 3 to prevent the nozzle unit 201 from continuing to slide and affect the spraying effect. Specifically, the above-mentioned locking assembly 3 includes a locking buckle 302 and a plurality of locking pieces 301, and the plurality of locking pieces 301 are uniformly and annularly arranged at one end of the nozzle unit 201, and there is a gap between two adjacent locking pieces 301. The gap and the locking piece 301 have certain elasticity. The outer surface of the locking piece 301 is provided with threads, and the above-mentioned locking buckle 302 is threadedly connected with the locking piece 301. When the locking buckle 302 is rotated for locking, the above-mentioned locking piece 301 is squeezed, and the adjacent locking piece 301 The gap between them is reduced to clamp the other sliding nozzle unit 201 , so that when the other nozzle unit 201 slides to any length, it can be fixed by the locking assembly 3 .

Further, both ends of the above-mentioned fixed pipe 1 are provided with locking assemblies 3 of the same structure to fix the sliding pipes 2 at both ends.

The regulating valve 7 is used to control the flow rate of the liquid in the connecting pipe 6, thereby controlling the spraying amount of the medicinal liquid. The distance between adjacent nozzles 202 will decrease when the nozzle unit 201 is adjusted. Therefore, when the overall length of the main body of the medicine rod is short, the distance between the nozzles 202 is too small, which will cause overlapping parts of the medicinal solution when spraying between the two nozzles 202, and the spraying concentration of the medicinal solution in this area is too high, which not only wastes Resources, may also harm crops, causing environmental pollution. At this time, the flow rate of the medicinal liquid is adjusted by the regulating valve 7 to ensure that the spraying rate is suitable.
