Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a spraying device used for spraying a chemical solution or the like for controlling pests and diseases, fertilizing, etc. in plant cultivation.

<Conventional example and problems> Conventionally, as this type of spraying device, a spraying nozzle is fixed above the field, for example, to the ceiling frame of a greenhouse, and the spraying nozzle is hung down on a suspension device installed reciprocally above the field. A mobile type is known, which is installed by lowering it so that chemicals can be sprayed from the side of the plant.

However, since the above-mentioned fixed type is sprayed only from above the plant, there is a serious drawback that the chemical solution cannot be sprayed to the back surface of the leaf, which is most susceptible to pest damage.

Also in the above-mentioned mobile type, a flexible liquid supply pipe is installed from the liquid storage tank installed outside the field to the suspension mechanism, and expands and contracts in a spiral according to the reciprocating movement distance of the suspension mechanism. According to this, a) The pipe is exposed to sunlight and spray chemicals, so that the chemicals are often deteriorated by ultraviolet rays and the like, or the pipe material is deteriorated and the chemicals are deteriorated. .

b) In the case where the pipe can be expanded and contracted while being spirally supported by a supporting member such as a rope, the longer the rope is, the larger the gathering width at the time of contraction is. Therefore, in a limited space such as a greenhouse, the width of the reciprocating stroke of the spray nozzle becomes shorter than the ridge length of the planting, which may prevent effective spraying work.

Therefore, as shown in Figs. 13a and 13b, the liquid supply tube (1
00) is looped around two moving pulleys (101) (102), the starting point (100a) of the annular tube is fixedly fixed, and the water cart (106) is connected to the opposite side.
Bogies (101) and (102) for moving pulleys on running rails
A method is known in which a tow rope is towed to the left and right by a tow rope (104) to reciprocate in an annular shape.
-59158). In the figure, (104) is a drive pulley, and (105) is a guide pulley.

However, in this structure, since the left and right carriages (101), (102) are towed while being connected to each other via the annular liquid supply tube (100), three pieces are provided in the liquid supply tube (100). Bogie (101), (10
2), a large load due to the load of (106) and frictional resistance during running. Therefore, accidents such as pulling damage of the tube and dropping of the joint portion of the base and the sprinkler truck are likely to occur.

Since the above liquid supply tube (100) is significantly stretched and loosened,
The distance between the bogies (101) and (102) is increased,
In many cases, the round-trip travel distance in 6) will not be as set.

Since the liquid supply tube (100) is formed in an annular shape,
Two left and right traveling vehicles are required to stretch and support this. Therefore, the drive pulley (104) and the guide pulley (1
If the interval with 05) is the total length of the erection, the effective spraying range of the sprinkler truck (106) is the total length of the erection minus the length of the two trolleys. In other words, when installed in a certain area such as a greenhouse, there is a portion that cannot be sprayed with a considerable width on either side of the moving end.

Also, the material cost of the dolly is high.

It is necessary to apply a strong tension to the tow rope (103) so that the liquid supply tube (100) does not fall off the left and right pulleys (101) and (102). However, in order to drive each trolley against strong tension, a large tension applying mechanism and a traction drive source (for example, a high-output motor),
In addition, a strong member structure that can withstand strong tension and driving force is required.

There are drawbacks such as.

<Means for Solving Problems> The present invention has been proposed in order to eliminate the above-mentioned drawbacks, and an object thereof is to spray a chemical solution or the like over almost the entire cultivation area in a field. To provide a mobile spray device.

Another object of the present invention is to prevent the flexible liquid supply tube for the movable part from being exposed to sunlight or spray chemicals, thereby preventing deterioration of the tube material and deterioration of the chemicals, and An object of the present invention is to provide a mobile spraying device having a structure in which a pulling force such as a pulling force for pulling and moving a spray nozzle does not act.

Still another object of the present invention is to provide a mobile spraying device having a stroke range without waste to at least one of the left and right ends of the erection device when the spraying nozzle reciprocates.

It is still another object of the present invention to provide a mobile spraying device that does not cause an excessive load on the liquid supply pump mechanism or the moving drive mechanism.

Therefore, the above-mentioned object of the present invention is, "In a mobile spray device for supplying a medicinal solution or the like to a cultivated plant, a guide rail of an appropriate length fixed substantially horizontally above the field scene, and a tube A pulley and two pulleys for tow ropes, which are arranged so as to be independently rotatable with respect to the tube pulley, are mounted, and a movable pulley carriage provided so as to be able to travel on the guide rail, and a field scene direction A distribution carriage for suspending and supporting a spraying mechanism in which one or more nozzles are provided on a terminal pipe hanging down, a guide pulley arranged near one end of the guide rail, and a guide pulley arranged near the other end of the guide rail.

(6) is a spray cart, the detailed structure of which is shown in FIGS. 5 to 7. However, in FIG. 2, only the cart chassis (61) and the mounting main plate (62) fixed upright to it are schematic. Is shown in.

(7) is a liquid supply tube made of a material that can be flexibly bent and has chemical resistance, pressure resistance, and tensile strength, such as nylon, and the base end ( 7a) is fixed, the intermediate portion is wound around the tube pulley (41) of the movable pulley carriage, the other end is fixed to the mounting main plate (62) of the spray carriage (6), and the pipe in the spray mechanism is fixed. It is linked to (69). (71) is a pipe joint provided at one end of the liquid supply tube (7), and
As shown in FIG. 9, the liquid supply tube (7) and the liquid supply main (152) are connected to each other by being slidably fixed to the outside of the lower surface near the guide rail (2).

The drive mechanism (5) includes an end unit (53) arranged at one end of the guide rail (2), a drive motor (51) arranged at the other end of the guide rail (2), and the drive motor (51). Drive pulley (52), which is driven to rotate by
It has a tow rope (54). The end unit (5
3) is an end pulley (56) for winding and supporting the guide pulley (55) and the tow rope (54) arranged on the base plate (53a), and is connected to the end of the tow rope (54) and has a predetermined tension. It has a spring member (57) as a tension adjusting member for applying the force. The spring member (57) may be provided on the fixed portion (54c) side of the tow rope (54) instead of being provided on the substrate (53a) side.

Here, it is assumed that the tow rope (54) comprises a short line portion (54a) and a long line portion (54b) having a length about twice that of the short line portion (54a) to form a one-to-one system. Thus, the short line portion (54a) has one end near the one end of the guide rail and the end pulley (5a).
6) is connected and fixed to the tension tension member via the rope, and is wound around one rope pulley (43a) of the moving pulley carriage (4), and the other end is attached to the main plate (62) of the spray carriage (6). ) One side is connected and fixed. On the other hand, the long line portion (54b) has one end fixedly fixed (54c) to the other end of the guide rail, that is, near the drive motor (51) side, and has an intermediate portion fixed to the rope pulley of the moving pulley carriage (4). (43b), drive pulley (52), guide pulley (5
The winding is performed in the order of 5), and the other end is connected and fixed to the other side of the main plate (62) of the spray truck (6).

Thus, when the tow rope (54) stretched with a predetermined tension by the end unit is towed by the drive motor (51), the moving pulley truck (41) and the spray truck (6) are pulled in either the left or right pulling direction. ) Runs on the guide rail at a speed difference of 2: 1. At this time, since both trolleys are wound so that the traction forces of the short line portion (54a) and the long line portion (54b) of the traction rope (54) act directly at the same time, This tractive force has no effect.

That is, as shown in FIGS. 11 and 12, the drive pulley (52)
When the tow rope (54) travels in the direction of the arrow due to the rotation of, the spray truck (6) travels on the guide rail (2) in the direction of the guide pulley (55) at the traveling speed twice that of the traveling pulley truck (4). Move to the left of the figure). At this time, since the liquid supply tube (7) is fixed at the position of the starting point, the moving pulley carriage (4) operates as a moving pulley. But,
This moving pulley carriage (4) itself is also a tow rope (54a) (5
Since the running traction force is directly received by 4b), the liquid supply tube (7) is flexed flexibly by receiving appropriate tension by the spring (73) as the tube pulley (41) and the spray cart (6) move. However, it only moves following, and is not affected by the strong tension caused by the traction force.

When the drive pulley (52) is rotated in the reverse direction, the movable pulley carriage (4) and the spray carriage (6) travel rightward, contrary to the above.

Moreover, of the left and right stroke ends in FIGS. 11 and 12, it is necessary to set the stroke width at the right end so that the spray carriage (6) stops when or immediately before contact with the moving pulley carriage (4). However, on the left side, the spreading carriage (6) can approach until just before the guide pulley (55), so that a large stroke width can be secured. In other words, it is possible to set the spraying range up to the end of the greenhouse.

5 to 10 show detailed structures of the guide rail (2), the spray mechanism (3), the spray carriage (4), the liquid supply tube (7) and the suspension mechanism (8).

The guide rail (2) is composed of a metal lip groove shape member having an opening groove on the upper surface and a substantially inverted convex cross section, and both side plates (21).

Since each mechanism incorporated in the inside is surrounded by the guide rail (2), it is not exposed to wind and rain and sunlight, and neither spray chemical liquid nor moisture adheres. Therefore, it is possible to prevent rusting and deterioration of the member. In particular, since the liquid supply tube (7) made of synthetic resin is stored in the inner bottom recess (25) of the guide rail (2), there is no fear of material deterioration due to ultraviolet rays or chemicals, and safe work can be performed for a long time. It will be possible.

The inclined upper end of the joint rail (200) is made to correspond to the bottom surface (23) of one guide rail (2) to be connected and the inclined lower end. Is positioned below the bottom surface of the other guide rail (2) to form an opening.

(202) (203) is a rail plate fixed to the side plate, and the insertion pieces (204) (205) (206) (207) are inserted into the adjacent guide rails (2) through the insertion openings (28) (29). Rail plate (24a) (24b) of the adjacent guide rail (2) by inserting it tightly into the
It is provided to connect with. (9) is a tube holding member, and is an outward flange (91) formed on the upper edge.
The inward flange (29
a) Engage (29b) and hang slidably,
The pipe joint (71) is stored and fixed. Thus, the liquid supply main pipe (152) is connected to one end of the pipe joint (71), and the base end (7a) of the liquid supply tube (7) is connected and fixed to the other end.

Reference numeral (730) is a tension member for the liquid supply tube, and the mainspring spring (73) is provided with a contraction curl on the shaft fixed to the flange portions (29a) and (29b) of the guide rail (2) by mounting fittings. Is fixedly installed, and the other end is connected to the rear end of the tube holding member (9). As a result, the tension is applied to the extent that the liquid supply tube (7) does not fall off the pulley (41) in the normal state. Therefore, an unreasonable pulling force does not act on the connection portion between the liquid supply tube (7) and other members, and a tension that causes the liquid supply tube itself to stretch does not operate. Further, even if the liquid supply tube (7) expands or contracts due to changes in ambient temperature or the like, the tube holding member (9) slides automatically by the spring (73) or a tension spring having a constant biasing force. An appropriate liquid supply tube length is adjusted.

Four wheels (63a) (63b) (63c) (63d) are attached to the chassis (61) of the spreading cart (6) and are provided so that they can travel on the rail plates (24a) (24b). Has been.
Reference numerals (64a), (64b), (64c) and (64d) are horizontal rollers that are rotatably provided so as to project from the side portion of the chassis (61) for attitude control, and are provided on both side plates (21) (22) of the guide rail. It abuts against the inner surface to prevent lateral movement of the spray carriage (6).

The upper end of the suspension frame (81) in the suspension mechanism (8) is connected and fixed to the upper portion of the mounting main plate (62). The suspension frame (81) is formed in a substantially rectangular frame shape so as to surround the outer periphery of the guide rail (2) (FIG. 7), and has a notch opening (8a) at its upper corner. A hanging metal fitting (26) is provided so that it can pass from the ceiling when traveling.
Reference numerals (81a) and (81b) are inclined wing arms attached to both sides of the suspension frame (81), and are arranged so as to extend substantially at right angles to the ridge (12) direction, and horizontal wing arms ( 82) is fixed.

Reference numerals (83a) and (84a) are metal fittings for fixing the pipe joints (83) and (84) to the suspension frame (81). (62
1) is a hole for inserting and fixing the end of the tow rope (54a), and (622) and (623) are holes that are movably provided through the tow rope (54b).

Further, since the liquid supply tube (7) and the liquid supply main (152) are always in a liquid-passing state, the spray carriage (6) is guided by the guide rail (2).
Not only when stopped above, but also during traveling, the chemical liquid or the like supplied from the liquid supply main pipe (152) receives the pipe joint (71), the liquid supply tube (7), and the pipe joint (83). It is possible to flow into the spraying mechanism (3) via (84).

The spraying mechanism (3) includes a main pipe (30), a plurality of terminal pipes (31) connected to the main pipe (30), and one or more spraying nozzles (32) attached to each terminal pipe (31). ing. The distance between the terminal pipes (31) is set appropriately according to the distance between the ridges (12), and the height of each spray nozzle (32) from the ground and the mutual spacing are determined by the type of plant to be cultivated and each spray. It should be properly set according to the spray range of the nozzle (32).

The chemical solution or the like in the liquid storage tank (150) is sucked up by the pump mechanism (151), and then reaches the pipe joint (71) by the liquid supply main pipe (152) which is piped to approximately the center of the guide rail (2). , Is fed under pressure to the liquid supply tube (7).

The control box (153) controls the rotation speed or rotation time of the drive motor (51) using an appropriate electric circuit to control the range of the reciprocating stroke of the moving pulley carriage (4) and the spreading carriage (6). It may be controlled.

<Effect> According to the present invention having the above-mentioned configuration and operation, the flexible liquid supply tube for the winding movable part is not exposed to sunlight or sprayed chemical liquid, and deterioration of the tube material or deterioration of the chemical liquid occurs. In addition, since the tension for pulling and moving the spray nozzle does not act on the liquid supply tube, there is no risk of the liquid supply tube falling off, or the stroke range significantly varying due to the extension of the liquid supply tube.

In addition, at the time of reciprocating movement of the spray nozzle, at least one of the left and right ends of the erection device can be within the stroke range without waste.

Further, an excessive load is not generated on the liquid supply pump mechanism or the moving drive mechanism.

Further, by storing and setting all the work processes in the control box (100), the spraying work can be performed fully automatically, which contributes to labor saving.
