Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a sprayer for spraying liquid pesticides and fertilizers, and a blower for blowing air to protect agricultural products from frost damage.

[0002]

[Prior art]

 As a conventional spraying machine, there is known a type in which pressure is applied by a pump to a tank containing a liquid to be sprayed and the liquid is sprayed in a frost form from a nozzle part. As for the blower, there is a "grass swinging air blower" (Jpn. Pat. Appln. No. 7-9972) for protecting the lawn from the damage of frost.

[0003]

[Problems to be solved by the device]

 The above sprayer type sprayer has a problem that it is difficult to spray a large amount of spray liquid to a long distance at a time. In addition, the blower used to prevent frost damage is used only during the winter, which causes a problem of low operating rate. Further, since the blower is driven by an electric motor, there is a problem that it cannot be operated in a place where there is no power source nearby.

The present invention solves these problems, can spray a large amount of spray liquid to a long distance, can be used as a blower to prevent frost damage, and can be operated even in a place without a power source. The purpose is to provide a spreader.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is characterized in that a spray liquid supply pipe having a plurality of injection ports is arranged so as to surround a blower port of an engine driven blower fan.

[0006]

[Embodiment of device]

 An embodiment according to the present invention will be described with reference to FIG.

FIG. 1 is a perspective view of a spreader of the present invention, in which 1 is a blower fan, 2 is a duct, and 3 is an engine for driving. A gasoline engine, a diesel engine, or the like is used as the engine 3.

Reference numeral 4 denotes a support base on which the duct 2 and the engine 3 are fixedly mounted.

The support base 4 is pivotally mounted on the carriage 5 so as to be rotatable about a main shaft 5 a fixed to the carriage 5.

Reference numeral 3a is a drive force transmission device that transmits the rotational power of the engine 3 to the drive shaft 1a of the blower fan 1. Further, the carriage 5 has a pair of wheels 5b and casters 5c, and further has a battery 5d and a fuel tank 5e mounted thereon.

The duct 2 has a cylindrical shape, and an annular spray liquid supply pipe 6 having a plurality of injection ports 6a is arranged around the blower port portion 2a, and the spray liquid supply pipe 6 is provided with a bracket 6b. It is locked to the duct 2 by the screw 6c.

Further, 6d is a valve for adjusting the supply amount of the spray liquid, and the arrow X indicates the supply direction of the spray liquid.

Further, a control box 7 is installed on the support base 4, and the control box 7 has a toggle switch for selecting an automatic operation or a manual operation, and whether or not the swing of a blower fan is required. Toggle switch for selecting and toggle switch for switching start / stop mode during automatic operation (neither shown) are installed.

Next, the operation of the embodiment of the present invention will be described.

When using as a sprayer for liquid pesticides or fertilizers, first start the engine drive fan, then pressure-feed the liquid fertilizers or pesticides to be sprayed in the direction of arrow X, and open valve 6d. The liquid is sprayed in the form of mist from each spray port 6a provided in the spray liquid supply pipe 6.

The ejected liquid is carried along with the air blown from the air blow port 2a, so that a large amount of liquid is scattered over a long distance. The arrow Y indicates the direction of air blowing.

When used as a blower for preventing the damage of frost in the winter, it may be operated without injecting the liquid.

When the toggle switch is set to the automatic operation, the start / stop of the driving engine 3 can be selected from the following three modes.

Arbitrary setting mode of start and stop times by a timer.

Arbitrary setting mode of start and stop temperature by the temperature sensor.

A mode in which both of the above conditions can be input at the same time.

By selecting these modes appropriately, it is possible to blow air at a time when frost is likely to occur, such as in the early morning, or to stop blowing air depending on the cold weather, thus saving labor due to unmanned operation. In addition to being saved, energy saving effects can be expected.

When only blowing air, the spray liquid supply pipe 6 may be detached from the duct 2 and used.

[0024]

[Effect of device]

 As described above, according to the present invention, a large amount of spray liquid can be scattered to a long distance, can be used as a blower for preventing frost damage, and can be used even in a place without a power source. Can be provided.
