Description

[Detailed explanation of the invention] This invention enables the jet pipe to be set and held at a desired position relative to the blower housing, regardless of whether it is for standing trees, shelf cultivation, prop cultivation, outdoor vegetable cultivation, tunnel cultivation, etc. This relates to a blower.

Traditionally, spray pipes used for pest control in orchards, afforestation areas, etc. are only capable of spraying one type of spray. For chemical spraying, it is necessary to have a dedicated jet pipe for shelving work, which not only makes pest control work complicated, but also leads to a significant increase in equipment costs, and it is difficult to improve work efficiency. I couldn't have expected it at all.

Therefore, in order to rectify the above-mentioned drawbacks, this invention aims to provide a sprayer that can quickly respond to the situation of the target and spray chemicals regardless of the target.
Discharge ports are provided at both ends of the sprayer inside the housing, facing each other, and one of the jet pipes communicating with each of these discharge ports is rotatably attached to the housing.

An embodiment of this invention will be described below with reference to the drawings. A casing V for housing a double-suction type centrifugal blower 1 placed in a suitable position of a device such as a traveling pest control machine (not shown) is shown below.
Discharge ports 2 and 3 are formed facing each other on both sides, and the roots of long tapered jet pipes 4 and 5 are connected to the discharge ports 2 and 3, respectively. An appropriate number of nozzles a and b are provided at predetermined intervals along the longitudinal direction of the nozzle 5, and one end (the upper end in FIG. 2) of the curved deflection body 6 is provided on the discharge port 3 side.
is rotatably fitted, and can be easily set and held on the housing V at any rotational position, and the root of the jet pipe 5 is attached to the other end (the right end in FIG. 2) of this deflection body 6. They are removably fitted and tightly attached.

Note that the deflection body 6 is provided with some elasticity so that once it is set, it can be held in its position well.

Since this device has the above-mentioned configuration, when using it, for example, if the jet tubes 4 and 5 are set at the positions shown by the solid lines in FIG. ，
After flowing into jet pipes 4 and 5 through nozzles 3 and 3, the chemicals are sprayed from nozzles a and b in opposite directions to control pests.

However, due to the difference in the objects to be controlled, for example, when the jet pipe 5 is used to control standing trees, when the direction changing body 6 is gripped and rotated relative to the casing V to direct it upward, the jet pipe 5 is also used. By taking the position shown by the chain line in Figure 1, you can effectively control standing trees.

According to this invention, the deflection body is rotatably fitted to one of the discharge ports of the casing that houses the blower, and the jet pipe is attached to this deflection body, so that the setting of the deflection body to the casing is easy. Since the state can be maintained depending on the position, one of the jet pipes can be set in the desired direction at any time as the target of pest control changes, which eliminates the conventional method of replacing the jet pipe only after the pest control work. In addition to being significantly simpler than the previous method, it does not require the use of a large number of ejection pipes in advance, resulting in a significant reduction in economic burden compared to conventional methods, and has practical benefits such as being extremely easy to handle. It is.
