Description

[Detailed description of the invention] [Industrial application field] This invention is a backpack-powered sprayer in which a small, lightweight trolley that can run on wheels is equipped with a backpack-powered sprayer and a spray pipe equipped with a nozzle. This invention relates to a spraying device for a spraying vehicle that sprays a chemical solution from a nozzle.

[Prior Art] Conventionally, in greenhouse cultivation, etc., a backpack power sprayer has been used to control seedlings during the seedling stage because the amount of chemical solution sprayed is small, and a portable power sprayer has been used during the harvesting period.

However, with these power sprayers, when controlling pests,
Because a large amount of water is used (100 to 300 water per 10 ares), it can lead to overhumidity in the greenhouse, which in turn increases the number of pests and diseases.Also, due to labor shortages and health problems for workers caused by pesticides, A small amount spraying method that sprays chemicals without using water (smoke,
(transpiration, fume, flow dust, small amount sprayer, etc.)
is often used. This method involves filling the entire greenhouse with chemical particles for pest control, and is fundamentally different from conventional pest control methods in which a chemical solution is directly sprayed only on crops.

Here, among the chemicals sprayed throughout the greenhouse using the small amount spraying method, those that adhere to vinyl or glass on the ceiling, walls, etc. may reduce the transmittance of sunlight, or the adhered chemicals may It can fall with morning dew and fall on workers, causing chemical damage.
In addition, it may adhere to the new shoots of young seedlings and inhibit their growth, and the odor of pesticides may accumulate inside the greenhouse.Furthermore, small amounts of spraying may not be effective against water-averse powdery mildew. For various reasons, in addition to spraying chemicals, clean water is sprayed using a power sprayer to clean the inside of the greenhouse.

[Problems to be solved by the invention] First of all, in the conventional power spraying machine, a portable power spraying machine requires at least two or more workers: one to operate the machine and the other to operate the hose;
Also, with backpack-powered sprayers, there is a limit to the amount of weight that one person can carry. There were problems such as poor efficiency and excessive strain on the neck, shoulders, and other parts of the body during long hours of work.

[Means for solving the problem] This invention was devised in view of the above-mentioned circumstances, and its outline is that a backpack-powered sprayer is removably mounted on a cart that can run on wheels, and , the spraying vehicle is equipped with nozzles arranged in a spray pipe that can be communicated with the backpack-powered sprayer via a pipe line, and the spray pipe has an arc shape and is arranged in pairs at the top and bottom, and has a spray pipe on one side. On the other side of the plate, a row of nozzles with a removable blind plate are installed, and by replacing the spray plate and the blind plate, the spraying direction can be selectively changed up or down. (2) In addition to cleaning greenhouses, it can also be used to control young seedlings and open-field crops. (3) (4) To provide a spraying device for a spray vehicle that can achieve a low-cost spraying system and (4) widen the scope of use of a backpack-powered sprayer.

[Embodiment] An embodiment of this invention will be described below based on the accompanying drawings.

Figures 1 and 2 are a rear view and a side view of the scattering vehicle of this invention. In the figures, 1 is a cart that can run on wheels 2, and the cart 1 has the wheels 2 pivoted on both left and right sides. The main body 3 has a flat plate shape, and a pipe frame 6 which is attached to surround the outer periphery of the main body 3 and is made by bending a pipe so that the entire body is upwardly U-shaped with rising portions 4 and 5 at the front and back. Be prepared,
A handle 7 for traveling is formed at the tip of the rear rising portion 5, and the front rising portion 4 serves as a mounting portion 4 for a spray pipe 23, which will be described later.

As shown in FIGS. 2 and 3, on the main body 3 of the cart 1, there is a backpack comprising a frame 8 bent into an approximately L-shape, and equipped with a chemical tank 9, a pump 10, an engine 11, etc. A power sprayer 12 is installed in a square hole 1 formed on the lower surface of the frame 8 in a square projection 13 (shown in the second figure) that projects onto the main body 3 of the truck 1.
4 (shown in Figure 4) is fitted, and then Figures 5 and 6 are fitted.
As shown in the figure, a hook 18 with a handle 17 is attached to the tip of a coiled spring 16 whose lower end is locked to the main body 3 and covered with a flexible pipe 15 made of vinyl or the like. , is removably mounted on the main body 3 by being removably hooked to guide pipes 19 erected on both left and right sides of the frame 8 using the elastic force of the spring 16 .

At the front part of the truck 1, there is provided a dowel, as shown in FIGS. 8 and 9, in which the mounting part 4 and the spray pipe 23 can be crossed and clamped by a pair of plates. The arc-shaped spray tube 23 (shown in the seventh figure) is fixed in place by a clamp 21 formed with a letter-shaped groove 20 and a screw 22. The spray pipe 23 has a pair of upper and lower discharge ports 24 and 25 at appropriate intervals.
Multiple holes are drilled. In addition, the spray pipe 23 has a first
As shown in Figure 0, when assembled, the spray tube 23
Opposite boss portions 29, 29 are formed so as to surround the discharge ports 24, 25 and face the discharge ports 24, 25, and around the boss portions, a circle is formed.
Nozzle holders 31 and 42 into which the rings 32 and 32 are respectively fitted are fastened by screws 33.
Also, the boss portions 29 and 2 of the nozzle holders 31 and 42
9 is provided with a through hole 34 that penetrates to the outside, and a gasket 35,
36 core 37 and one side holder 31 have a spout plate 38,
On the other side holder 42, nozzles 40 and 43 are formed which are superimposed in the order of blind plate 41 and fixed by nozzle caps 39 and 39, respectively. Therefore, by replacing the spout plate 38 and the blind plate 41,
The spray direction of the nozzle can be selectively changed.

As shown in FIG. 7, blind plates 44 and 45 are attached to both ends of the spray pipe 23, respectively.

Further, as shown in FIG. 7, an inlet 46 is bored approximately in the center of the spray pipe 23.
The boss part 4 has a threaded part 47 formed on the outer edge of the boss part 6.
8 is formed. An end connecting portion 50 of a connecting hose 49, which is a conduit communicating with the discharge port of the pump 10 of the backpack power sprayer 12, is screwed to the threaded portion 47 of the boss portion 48.

[Effects of the invention] Since the scattering wheel according to this invention is as described above, it has the effects described above.

(1) As shown in Figure 11, operate the backpack power sprayer 12 and hold the handle 7 of the trolley 1 while spraying clean water from the nozzle 40 to the central furrow 6 in the house 60.
By spraying 1 backwards, a single working vehicle can easily and efficiently clean the inside of one house 60.

(2) By spraying a chemical solution instead of the above-mentioned fresh water, in addition to cleaning the inside of the greenhouse 60, it can also be used to control young seedlings and open field crops.

(3) Since the backpack power sprayer 12 can be used as is, an inexpensive spray system can be achieved.

(4) Furthermore, the range of use of the backpack power sprayer 12 can be expanded.
