Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides water, water, and
Spray liquid, fertilizer, chemical solution, etc., watering, pest control,
This invention relates to an agricultural and horticultural spraying device used for cooling, etc.

Conventionally, in the case of this type of agricultural and horticultural spraying equipment, in which a sprayer such as a spraying nozzle is configured to spray a spray liquid while moving within a greenhouse, for example, the method disclosed in Japanese Utility Model Application Publication No. 150013/1983 has been proposed. Such devices as agricultural spray liquid devices have been proposed. The main body is made of a pipe material, and the upper half of the U-shaped part has a motor and a drive wheel driven by the motor, and the drive wheel is biased by a spring and has an approximately inverted T-shaped cross section. A guide wheel is installed that presses and rolls the left and right horizontally extending parts of the guide rail at the top and bottom, and the lower half has a liquid supply pipe extending from the bottom rod of the U-shaped part and a liquid spray pipe connected to the liquid supply pipe. A liquid guide hose is connected to the liquid supply pipe, and a power supply line is connected to the motor.

However, the above-mentioned agricultural spraying liquid device moves the guide rail by the rotation of the drive wheel of the drive traveling mechanism provided on the main body itself, so it is difficult to pull the liquid guiding hose which is filled with sprayed liquid and becomes quite heavy. When installed in a large greenhouse and the liquid guide hose is quite long, or when there is sprayed liquid on the guide rail, slippage may occur between the drive wheels and the guide rail, making it impossible to move the entire main unit. There was a problem.
In addition, the main body tends to swing in the longitudinal direction (back and forth) of the guide rails and in the left and right directions when traveling, and furthermore, the main body has a considerable weight due to the addition of liquid supply pipes and liquid spray pipes. If this weight becomes greater than the elastic force of the spring that presses the drive wheel against the lower surface of the guide rail, there is a problem in that the main body cannot be moved. In addition, the main body tends to swing in the turning direction, and if the main body swings in the turning direction while traveling, there is a risk that the vertical part of the main body will catch on the guide rail, making it impossible to move. There was a risk that the main body would get caught, especially at the joints of the guide rails, making it impossible to move. By the way, a considerable weight is applied to the guide rail, and there is a possibility that the longitudinal center portion of the guide rail may be bent downward.

Therefore, the present invention was created in order to solve the problems that existed in the past as described above, and the gist is that the running rail is connected to the running rail via a plurality of support rods suspended from the ceiling at appropriate intervals. The dispersing body is equipped with a dispersion device, which forms a self-propelled body that can move freely on the running rail by a drive mechanism consisting of a built-in motor, etc., and a support driven body that freely runs on the running rail, and is equipped with a dispersing device. is attached to the self-propelled body, a hose that is connected to the dispersion body and supplies the spray liquid to the sprayer is supported by a support driven body, and the support driven body and the hose follow the movement of the self-propelled body, It is formed so that the spray liquid can be sprayed along the track of the running rail, and the running rail is connected to a pair of rail pipes having a circular cross section, and a pair of rail pipes arranged at appropriate intervals in the longitudinal direction of the rail pipes. A pair of rail pipes are arranged in parallel at a constant interval, and a support rod can be attached to the center of the rail support material, and a support rod can be attached to the center of the rail support material. is fixed so as to hold the lower circumferential surface of each rail pipe, and matches the rolling surface of the driving wheels and running wheels of the self-propelled body and supporting driven body, and the upper curved surface of the rail pipe. This is due to the fact that a groove is provided around the circumference.

Hereinafter, the present invention will be explained with reference to illustrated examples.

In the figure, reference numeral 1 indicates a running rail, and this running rail 1 is installed above the materials to be sprayed, such as plants, via a plurality of support rods 2 suspended from the ceiling at appropriate intervals. will be placed. For example, as shown in FIG. 4, the running rail 1 may be bent as appropriate so that the spray liquid can be sprayed over the entire surface of the greenhouse H, or it may be arranged in a straight line.

The traveling rail 1 includes a pair of rail pipes 1a, 1a made of round pipes, and this rail pipe 1.
It is comprised of a pair of rail pipes 1a, which are arranged at appropriate intervals in the longitudinal direction of a, and a rail support member 1b that connects the rails 1a to each other. Moreover, the pair of rail pipes 1a, 1a are arranged in parallel with a constant interval, and the rail support member 1b has a support rod 2 that can be attached to the center thereof, and both ends of the support rod 2 can be attached to the lower circumference of each of the rail pipes 1a. It is fixed to the rail pipes 1a, 1a so as to hold the surface portion.
The rail pipe 1a itself is made of a lightweight metal material such as aluminum pipe material in order to reduce weight and improve workability (such as bending it into a curved shape), but it is not limited to this. isn't it.

The support rod 2 is formed to be extendable and retractable so that the height can be adjusted when the running rail 1 is arranged in an erected manner, and the work of arranging the running rail 1 in an erected form can be easily performed. It's okay.

3 is a self-propelled body formed so that it can freely move on the traveling rail 1 by a drive mechanism 4 consisting of a built-in motor and the like. This self-propelled body 3 is provided with four wheels, one of which serves as a drive wheel 9, and this drive wheel 9 is linked to the drive mechanism 4. That is,
The rotational force of the motor in the drive mechanism 4 is transmitted to the drive wheels 9 via the drive transmission wheel 5, the transmission band 6, the driven transmission wheel 7, and the drive shaft 8, and the drive wheels 9 are configured to rotate. There is. The running wheels 10 other than the drive wheels 9 are rotatably supported via a support shaft 11 . Note that the specific configuration of the drive mechanism 4 is not limited to the above-mentioned one, but is formed so that the rotational force of the motor is transmitted to the drive wheels 9 so that the self-propelled body 3 can reliably travel on the traveling rail 1. That's fine.

The above-mentioned self-propelled body 3 is provided with a dispersing body 15 which is equipped with a dispersing device 16 at the lower end that can spread the dispersing liquid over a wide area. The tip portions of the supply hoses 30 are connected.

The sprayer 16 attached to the sprayer 15 is configured to automatically rotate by utilizing the reaction force generated by spouting the spray liquid, so that a good spraying condition can be obtained over a wide range. You can use a rotary spreader or a spray nozzle,
Any other material may be used as long as the spraying condition of the spray liquid is good.

The hose 30 is supported by the running rail 1 via a supporting follower body 20 having running wheels 21 that freely rolls on the running rail 1, and can follow the spreading body 15 fixed to the self-propelled body 3. It is formed like this. That is, when the self-propelled body 3 is near the base end of the traveling rail 1, the hose 30 is arranged so that it is coiled in a substantially spiral shape as shown in FIG. Consideration has been taken to ensure that the supply is not cut off midway through. In particular, the support driven body 20 is formed so that the portion to which the hose 30 is attached and the portion to which the running wheels 21 are attached are rotatable in the horizontal direction, thereby preventing twisting of the hose 30 itself. I'm starting to be able to do it. Moreover, due to these, the hose 30 in a spiral state can smoothly and quickly follow the movement of the self-propelled body 3 without being twisted or bent.

The self-propelled body 3 and the support driven body 20 are formed in the shape of a generally lip channel steel with an open upper side, and are constructed so as to straddle the pair of rail pipes 1a, 1a of the traveling rail 1 from below. In addition, the drive wheels 9 and the running wheels 1 in the self-propelled body 3 and the support driven body 20
The rolling surfaces 0 and 21 are provided with concave grooves that match the upper curved surface of the rail pipe 1a.
Note that the self-propelled body 3 and the support driven body 20 may be formed so as not to derail from the running rail 1 and to be able to run smoothly on curves and straight sections.

Reference numeral 31 indicates a power transmission line, and this power transmission line 31 is attached to the hose 30 for supplying current to the motor built in the self-propelled body 3. P is a pump for feeding the spraying liquid into the hose 30 and spraying it from the sprayer 16. C indicates a control box, and this control box C is
Adjusts the pressure of the pump P, the current applied to the motor, etc., controls the moving speed, moving range, moving time, number of moves, etc. of the self-propelled body 3, and controls the spraying pressure of the liquid to be sprayed, etc. It is designed so that it can be done.

The present invention is constructed as described above, and the control box C adjusts the current supplied to the motor and the pressure of the spray liquid sent to the sprayer 16 so that the optimum spraying condition can be obtained. The self-propelled body 3 moves on the traveling rail 1 while spraying the spray liquid, and the hose 3 connected to the spray body 15
0 follows the dispersion body 15, and the support driven body 2
0 follows, and the spray liquid is spread along the trajectory of the traveling rail 1.
