Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an agricultural and horticultural spraying device that is installed in a greenhouse, a livestock barn, etc., and is used to spray spray liquids such as water, liquid fertilizer, and chemical solutions for watering, pest control, cooling, etc. Regarding.

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 pipe material, and the upper half of the U-shaped part has a motor, a drive wheel driven by the motor, and a spring-biased drive wheel that clamps the guide rail at the top and bottom. The lower half consists of 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. The power supply lines are connected to the respective power supply lines.

However, since the guide rail is moved by the rotation of the drive wheel of the drive traveling mechanism installed in the main body itself, it is difficult to install it in a large greenhouse when towing a liquid guide hose that is filled with spray and becomes quite heavy. When the liquid guiding hose becomes quite long, or when the guide rail is covered with sprayed liquid, slipping occurs between the drive wheels and the guide rail, making it impossible to move the entire main body. . Moreover, the main body easily swings in the longitudinal direction (back and forth direction) of the guide rail and in the left and right directions while traveling, and furthermore, the main body
The addition of liquid supply pipes and liquid spray pipes adds considerable weight, and if this weight becomes greater than the elastic force of the spring that presses the drive wheels against the bottom surface of the guide rail, the main body will become unable to move. There was a problem. 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 and become unable to move. In particular, there was a risk that the main body would get caught 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.
Moreover, when the main body travels far away, there is a problem in that control becomes difficult due to changes in voltage and current that occur in the control distribution lines.

Also known is a water sprinkler device disclosed in Japanese Patent Application Laid-Open No. 48-21808. This includes a running frame that can move along a rail and has water nozzles;
a drive device that moves the traveling frame intermittently;
It consists of a water supply device that sprays water from the nozzle when the traveling frame is stopped.The traveling frame is mounted on two parallel rails, and a wire is attached to each of the wires wound around drums placed at both ends of the rails. is fixed, and the traveling frame moves on the rails as the drum rotates.

However, since the rails are installed on both sides of the greenhouse, the running frame itself mounted on the two rails has a length that extends from near one side wall of the greenhouse to near the other side wall. Two cables are installed on the left and right to pull this horizontally long running frame in parallel.
Disadvantages include the need for a long drum that can wrap two cables, etc., making the entire watering system large-scale, and the watering system taking up a considerable amount of space inside the greenhouse, as well as the difficulty of installing the watering system easily. It was hot. Moreover, it is difficult to work inside a greenhouse.

Furthermore, there are devices such as the chemical spraying device disclosed in Japanese Utility Model Publication No. 42-1100. This is a system for attaching and detaching a mobile vehicle equipped with a rotating wheel movable along the frame body that can be used for a track such as a frame extending from one end of the greenhouse to the other end. A jet pipe was attached to the mobile vehicle, and the hose was strung between a rotary wheel provided facing the side end of the frame and a hose coil mounted on a traveling vehicle located outside the greenhouse. A portion of the cable is fixed, and a flexible tube that is wound around the hose and communicates with a supply source of medicine or the like is connected to the squirt tube.

However, this has the disadvantage that the track has a substantially inverted T-shaped cross section, and that a large number of rotating wheels are required to sandwich the lower left and right horizontally projecting portions from above and below. Moreover, although it has become difficult for mobile vehicles to swing from side to side, they do tend to swing in the turning direction, and a considerable amount of weight is placed on the track, causing the longitudinal center portion of the track to move downward. There was also the problem of bending. Furthermore, since cables are placed above the track, it is difficult to support the middle part of the track from the ceiling, and it is also difficult to pull the moving vehicle smoothly. Furthermore, since the traveling vehicle, hose coils, etc. are located outside the greenhouse, it is difficult to carry out all the work inside the greenhouse.

Therefore, the present invention was created in order to solve the conventional problems as described above, and the gist thereof is to suspend a plurality of rail support rods at appropriate intervals from the ceiling of a greenhouse, etc. A single running rail is installed horizontally above the center of the greenhouse through the plurality of rail support rods, and the running rail is made of angle-shaped steel with a pair of left and right slopes that widen as it goes downward. A drive wheel driven by a motor, etc. is installed below one end of the running rail, and a driven wheel is rotatably supported below the other end of the running rail. A driven vehicle whose position on the driven vehicle support body can be freely adjusted is installed, and a transmission band disposed below the traveling rail is wrapped around the driving vehicle and the driven vehicle, and the driving vehicle is rolled on the left and right inclined surfaces of the traveling rail. A running body with movable running wheels is fixed to a transmission band, a spreading body having a sprayer is attached to the running body, a hose for supplying a spraying liquid is connected to the spreading body, and the hose is connected to the running rail. It is supported by a hose supporting traveling body having running wheels that can freely roll on left and right inclined surfaces, and a plurality of sprayers are arranged on the spreading body along a direction substantially perpendicular to the moving direction of the traveling body. The running wheels of the running body are also arranged in the longitudinal direction of the running rail, and are composed of four or more wheels in total, and their rolling surfaces are in close contact with the left and right inclined surfaces of the running rail. It is pivoted on the upper end of the wheel support frame in a tilted state,
This consists in that the wheel support frame is formed so as to straddle both side edges of the running rail from below.

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 suspended from the ceiling of the greenhouse H, etc., and is horizontally extended above the center of the greenhouse H via a plurality of rail support rods 2 arranged at appropriate intervals. It is installed above the object to be sprayed, such as plants, to be sprayed. By the way, the traveling rail 1 itself is made of a shaped material such as angle steel having a pair of left and right inclined surfaces 1a that widen as they go downward. Furthermore, this traveling rail 1
Other shapes may be used, and the specific means for constructing the traveling rail 1 can be freely set as appropriate.

A drive wheel 3 connected to a motor is installed below one end of the traveling rail 1, and a driven wheel 4 rotatably supported by a driven wheel support 6 is installed below the other end. has been done.

An endless annular transmission band 5 is wound around the drive wheel 3 and the driven wheel 4, and the transmission band 5 is disposed below the traveling rail 1. Furthermore, in order to prevent the transmission band 5 from loosening, the driven vehicle 4 is pivotally supported by a driven vehicle support 6 such that its mounting position can be adjusted in movement along the longitudinal direction of the traveling rail 1.

The traveling rail 1 is provided with a traveling body 1 so that the traveling wheels 11 can freely roll on the left and right inclined surfaces 1a.
0 is attached. Moreover, this running body 10
is fixed to the transmission band 5, and is formed so that it can reciprocate on the running rail 1 while being pulled by the transmission band 5.

The running wheels 11 of the running body 10 are arranged also in the longitudinal direction of the running rail 1, and are constituted by a total of four wheels on the front, rear, left and right sides, and furthermore, the rolling surfaces 11a of the running wheels 11 are disposed in the longitudinal direction of the running rail 1. The upper end portions of the wheel support frame 10a are respectively pivotally supported in an inclined state so as to come into close contact with the left and right inclined surfaces 1a of the wheel support frame 10a. Moreover, the wheel support frame 1
0a is formed so as to flank both side edges of the running rail 1 from below. By the way, the specific structure of the traveling body 10 is not limited to the illustrated example and can be freely set as appropriate.

The traveling body 10 is attached with a dispersing body 20, which is formed by attaching a large number of dispersing devices 21 to a liquid sending pipe 22 to enable dispersion according to the purpose.

This dispersion body 20 has a liquid feeding pipe 22 connected to the traveling rail 1.
As long as it is arranged in a direction substantially orthogonal to the greenhouse H and is formed so as to reach from one side wall to the other side wall of the greenhouse H, it can be freely set as appropriate. In addition, when there is a risk that the liquid feeding pipe 22 becomes long and bends, use a wire stretched appropriately in the greenhouse H along a direction approximately parallel to the longitudinal direction of the traveling rail 1. It is also possible to prevent the liquid feeding pipe 22 from being bent or the like (not shown).

As shown in FIG.
The liquid feeding pipe 22 may be attached via the fifth
As shown in the figure, the liquid feed pipe 22 is connected via the hanging pipe 24.
It may also be attached to the holder so that it can be evenly sprayed on the undersides of leaves of plants, etc. Furthermore, the sprayer 21 itself is also used as appropriate depending on its purpose.

A hose 40 for supplying the spraying liquid to the sprayer 21 is connected to the liquid sending pipe 22 of the sprayer 20 .

The hose 40 is supported by a hose supporting running body 30 having running wheels 31 that freely roll on the left and right inclined surfaces 1a of the running rail 1, and a running body 10 that is pulled by a transmission belt 5 that moves in a rotary manner. It is formed so that it can follow the dispersion body 20 fixed to.

Moreover, when the running body 10 and each of the hose supporting running bodies 30 are in close proximity, the hose 40 is supported in a substantially spiral manner as shown in FIG. 2, and the hose 40 itself is bent. This is designed to prevent the supply of spray liquid from being cut off midway.

That is, the hose support running body 30 is formed so that the portion to which the hose 40 is attached and the portion to which the running wheels 31 are attached are rotatable in the horizontal direction, and are formed in a substantially spiral shape. The hose 40 is configured to be easily tied together and to prevent twisting of the hose 40 itself.

In addition, the running wheels 31 of the hose supporting running body 30
The traveling body 10 and the traveling wheels 11 are respectively pivotally supported on the upper end portions of the wheel support frames 30a in an inclined state such that the rolling surfaces 31a are in close contact with the left and right inclined surfaces 1a of the traveling rails 1. Moreover, the wheel support frame 3
0a is to prevent falling from the running rail 1,
It is formed to straddle both side edges of the traveling rail 1 from below. In the illustrated example, the running wheels 31 of the hose supporting running body 30 are composed of two left and right running wheels 31 that are in close contact with the left and right inclined surfaces 1a of the running rail 1 in order to reduce the weight thereof. There are, but
Similar to the running wheels 11 of the running body 10, in order to improve running stability and the like, it may be configured with a total of four wheels, front, rear, left and right, or more than four wheels (not shown). Further, the specific structure of the hose supporting traveling body 30 is not limited to the illustrated example, and can be freely set as appropriate.

By the way, in order to use the hose 40 not only for one greenhouse H but also for other greenhouses H, the hose 40 itself may be detachably used.

In the figure, reference numeral 12 denotes a running body 10 which has a groove for guiding the transmission band 5 and prevents the transmission band 5 from loosening.
13 is a guide roller attached to the guide roller, and 13 is a running body pressing piece that presses the hose supporting running body 30. 1
Reference numeral 5 denotes a lead wire that connects the limit switch 14 attached to the traveling body 10 and the motor, and is attached to the hose 40. Reference numeral 16 denotes a switch operating body that is attached to the traveling rail 1 or the like in order to operate the limit switch 14. The limit switch 14 may be used by being attached to the traveling rail 1 or the like instead of being attached to the traveling body 10. 32
has a groove for guiding the transmission band 5, and a hose supporting running body 3 to prevent the transmission band 5 from loosening.
This is a guide roller attached to 0. Note that the guide rollers 12 and 32 do not need to be attached to the traveling body 10 or the hose supporting traveling body 30.

The present invention is constructed as described above, and its use will be explained next. First, the driving rotational force of the motor is transmitted to the transmission band 5 via the drive wheel 3, and the traveling body is pulled by the transmission band 5. 10 to move (run). When the traveling body 10 moves, the hose supporting traveling body 30 is towed via the hose 40, and the hose 40 itself follows the spreading body 20. At the same time, the spray liquid is sent into the hose 40 via the pump, and is sprayed from the sprayer 21 attached to the spray body 20 over the entire inside of the greenhouse H or only to the necessary parts. When the limit switch 14 attached to the traveling body 10 comes into contact with the switch operating body 16, the traveling body 10 stops,
Or it will automatically start running in the opposite direction. When moving in one direction, the hose supporting running body 30 is towed via the hose 40, but when moving in the other direction, it is sequentially pressed by the running body pressing piece 13 attached to the running body 10. Be moved.

Note that the traveling body 10 may be automatically and repeatedly moved a desired number of times using the limit switch 14 or the like, or automation by other appropriate means may be employed.

By the way, in addition to being installed in a greenhouse H, the spraying device of the present invention can also be installed in a livestock barn and used for disinfecting livestock, cooling with fine mist, and the like.

Therefore, in the present invention, a plurality of rail support rods 2 are hung from the ceiling of a greenhouse H, etc. at appropriate intervals, and a single running rail 1 is connected above the center of the greenhouse H, etc. via the plurality of rail support rods 2. installed horizontally, and running rail 1
The rail is made of a shaped material such as angle-shaped steel with a pair of left and right sloped surfaces 1a that widen as it goes downward, and a drive wheel 3 driven by a motor or the like is mounted below one end of the running rail 1. A driven vehicle 4 is installed below the other end of the traveling rail 1 and is rotatably supported by a driven vehicle support 6 and whose position on the driven vehicle support 6 is adjustable. A transmission band 5 disposed below the running rail 1 is wound around the car 3 and the driven car 4, and a running body 10 having running wheels 11 that can freely roll on the left and right inclined surfaces 1a of the running rail 1 is attached to the transmission band 5. A spreading body 20 having a sprayer 21 is attached to the running body 10, and a hose 40 for supplying a spray liquid is connected to the spreading body 20. Freely movable running wheels 31
The sprayer 20 is supported by a hose support running body 30 having a
The running wheels 11 of the running body 10 are also arranged in the longitudinal direction of the running rail 1, so that a total of four or more wheels The rolling surface 11a is pivotally supported on the upper end portion of the wheel support frame 10a in an inclined state such that it is in close contact with the left and right inclined surfaces 1a of the running rail 1, and the wheel support frame 10a is connected to both side edges of the running rail 1. Since the spraying device is formed so as to straddle from below, the spraying device can be installed in the greenhouse H etc. very easily without requiring large-scale equipment or reinforcing the greenhouse H etc. Furthermore, the configuration of the spraying device itself is simplified, and its weight can be significantly reduced.

Moreover, the spreading body 20 can be freely moved along the running rail 1, and the spreading body 20 can be moved freely along the traveling rail 1.
The hose 40 connected to the hose 40 can be smoothly moved to follow the movement of the dispersion body 20 without being twisted or bent. Further, the spraying liquid can be sprayed from the sprayer 21 while moving the spraying body 20, and the spraying liquid can be spread over a wide range. By the way, the plurality of spreaders 2 attached to the spreader 20
1 is arranged along a direction substantially perpendicular to the direction of movement of the traveling body 10, making it possible to spray over a wide area, further expanding the spraying range, and uniformly spreading in a short period of time. The spray liquid can be sprayed efficiently.

In particular, a plurality of rail support rods 2 are suspended from the ceiling of the greenhouse H, etc. at appropriate intervals, and one running rail 1 is horizontally mounted above the center of the greenhouse H, etc. via the plurality of rail support rods 2. Therefore, the running rail 1 can be installed at a high position in the center of the greenhouse H (near the ceiling) so as not to get in the way of workers.
can be horizontally mounted stably by a plurality of rail support rods 2, and can also be
It is possible to reliably prevent the longitudinal center portion of the running rail 1 from bending downward due to the weight of the rail 1 and the hose supporting running body 30, the load applied thereto, and the like.
Furthermore, it becomes possible to use a long traveling rail 1.

Further, the running rail 1 is made of a shaped material such as an angle steel material having a pair of left and right inclined surfaces 1a that widen as it goes downward, and the running rail 1
are also arranged in the longitudinal direction of the running rail 1, and are composed of four or more wheels in total, and their rolling surfaces 11a are the left and right inclined surfaces 1a of the running rail 1.
Since the wheel support frame 10a is pivotally supported on the upper end portion of the wheel support frame 10a in a tilted state such that it is in close contact with The load etc. applied to the left and right inclined surfaces 1a of the traveling rail 1
The rolling surface 11a of the left and right wheels 11 of the traveling body 10 is brought into close contact with each other, and the rolling body 10
The rolling surface 11a of the left and right running wheels 11 is the running rail 1.
The running body 10 acts to pinch the left and right inclined surfaces 1a of the running rail 1 in the left-right direction, and the running body 10 presses against the running rail 1 in the left-right direction perpendicular to the longitudinal direction (moving direction of the running body 10), in the front-back direction, and in the front-back direction. , it is extremely difficult to swing in the turning direction, and the traveling body 10 does not wobble or wobble in these directions, and excellent running stability can always be obtained. Moreover, the running body 10
Even if an unexpected external force acts on the device that causes it to wobble or wobble in these directions, the wobbling or wobbling will quickly subside.

That is, supporting the running wheels 11 of the running body 10 on the upper end portion of the wheel support frame 10a in an inclined state P such that the rolling surface 11a thereof is in close contact with the left and right inclined surfaces 1a of the running rail 1 is advantageous for the running rail 1. This prevents the running body 10 from swinging in the left-right direction perpendicular to the longitudinal direction of the running rail 1, and in conjunction with this, the running wheels 11 of the running body 10 are also arranged in the front-rear direction, which is the longitudinal direction of the running rail 1. Therefore, it is necessary to have a total of four or more wheels in the longitudinal direction of the traveling rail 1,
This prevents the traveling body 10 from swinging in the turning direction.

By the way, the liquid feed pipe 22 of the dispersion body 20 is arranged along a direction substantially perpendicular to the traveling rail 1, and is formed long enough to reach from one side wall of the greenhouse H etc. to the other side wall. In many cases, even a slight wobbling of the traveling body 10 in the left-right direction or turning direction can cause the both ends of the liquid feeding pipe 22 to swing significantly, which may cause damage. Stability in direction and turning direction is particularly required, and this requirement can be fully satisfied.

Moreover, by forming the wheel support frame 10a so as to straddle both side edges of the running rail 1 from below, there is no possibility that the running body 10 will fall off the running rail 1.

Further, a drive wheel 3 driven by a motor or the like is installed below one end of the running rail 1, and is rotatably supported by a driven wheel support 6 below the other end of the running rail 1. A driven vehicle 4 is installed, and a transmission belt 5 disposed below the traveling rail 1 is wrapped around the driving vehicle 3 and driven vehicle 4, so that the intermediate portion of the traveling rail 1 is connected to the greenhouse through the rail support rod 2. It becomes easier to support from the ceiling of H etc. Moreover, the traveling body 10 can be forcibly moved by the transmission band 5, and
The traveling body 10 having its center of gravity below the traveling rail 1 can be smoothly towed. By the way, when the dispersing device is installed in a large greenhouse H or the like, the traveling rail 1 becomes quite long and the load when towing the traveling body 10 becomes considerably large, but the traveling body 10 can be moved reliably. In addition, it can be used continuously for a long time, is less likely to break down, and has excellent durability.

Since the driven wheel 4 is installed so that its position on the driven wheel support 6 can be adjusted, it can be adjusted so that the winding state of the transmission band 5 is optimal.
