Description

[Detailed Description of the Invention] This invention relates to a ridge sprayer for uniformly spraying pesticides and the like onto ridges.

In upland farming, crops are usually grown in rows on cultivated land. On the other hand, spraying pesticides and other chemicals is essential for growing crops, but this work is a large labor burden for farmers.

There are many technical difficulties in spraying pesticides on ridged farmland. For example, fungicides, insecticides,
When trying to uniformly spray herbicides, liquid fertilizer, liquid mulch, etc. over the entire curved ridge surface, conventionally known sprayers are all inconvenient. The operator had to hold the entire weight of the sprayer by hand and constantly swing the nozzle back and forth and from side to side to make adjustments. Even with this method, uneven distribution cannot be avoided, even by experienced personnel.

In addition, in many cases, it is sufficient to spray pesticides on the ridges where crops are planted, and it is not preferable to spray them between the ridges in order to save on the amount of pesticides.
With conventional sprayers, it was impossible to uniformly spray the chemical solution only on the ridge surface.

This invention aims to correct the above-mentioned drawbacks of conventional sprayers and provide a ridge sprayer that can easily and uniformly spray a chemical solution onto the ridge or crops planted thereon. It is something.

An embodiment of this invention will be explained with reference to Fig. 1. In the figure, 1 is a nozzle, 2 is a bent pipe bent into a semicircular shape, 3 is a bendable grounding member, 4 is a chemical liquid guide rod, 5 is a chemical liquid pipe, and 6 is a cock. The chemical liquid pipe 5, which communicates with a chemical liquid tank (not shown),
The tip of the liquid introduction rod 4 is connected to the top of the curved pipe 2, which is the midpoint of the curved pipe 2. The curved pipe 2 has a semicircular shape and is provided with a plurality of nozzles 1 facing inward of the semicircular shape.
The bent pipe 2 is provided with bendable grounding members 3 at both ends.
is made up of wire-like material, for example.
It can be easily bent by hand from the required part. The end a of the bent ground member 3 that is parallel to the ground is in contact with the ground, and this part supports the weight of the sprayer. The height of the bent pipe 2 is determined by the length b from the attachment part of the ground member 3 to the bent part. By changing the bending position, the height between a and b is determined.
By changing the ratio, the effective height of the nozzle 1 relative to the ridge can be changed.

The chemical liquid supplied under pressure from the chemical liquid tank reaches the curved pipe 2 through the chemical liquid guide rod 4 by opening the pot 6, and is sprayed from the nozzle 1.

When spraying on the ridge, the worker should use the chemical solution guide rod 4.
Hold the curved pipe 2 over the ridge, and while grounding the grounding member 3 at the ridge position, open the pot 6 and proceed along the ridge. By doing so, the chemical solution sprayed from the nozzle 1 can be uniformly distributed over the ridge surface. As mentioned above, the distance between the nozzle 1 and the ridge can be adjusted as appropriate by adjusting the degree of bending of the ground contact member 3, so the distance between the nozzle 1 and the ridge can be made as close as possible to ensure efficient spraying of the chemical solution. becomes possible. Furthermore, by changing the bending direction of the ground-contacting member 3, the operator can spray while pushing or pulling the ridge spreader as necessary. Furthermore, by changing the bending portions of the left and right ground contact members 3, uniform spraying can be similarly applied to the ridges of sloped land.

By using the ridge sprayer of this invention, uniform spraying can be easily performed on the ridges, not only on flat ground but also on sloped land, and stable spraying is possible with almost no influence from wind. There is almost no danger that the sprayer will be exposed to chemical droplets, and the chemical can be sprayed efficiently. Further, since most of the weight of the bent pipe provided with the nozzle is supported by the grounding member, the labor of the operator is significantly reduced.
