[Industrial applications]

 The present invention relates to a liquid spraying work vehicle used in farms, orchards, golf courses, etc., which can be used according to various applications and places, and can be manufactured efficiently and easily maintained. Moreover, it is characterized by diversifying the uses of self-propelled carriages.

[0002]

[Prior art]

 Conventionally, so-called speed sprayers and the like have been provided as liquid spraying work vehicles. The speed sprayer is configured to run freely, and supplies chemicals or the like to a large number of spray nozzles opened at the air outlet of the blower provided at the rear part, and the chemicals or the like sprayed from the large number of spray nozzles are blown from the blower. It is diffused and scattered by blowing air (see Japanese Utility Model Publication No. 58-2223, etc.).

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional speed sprayer has a limited use, and since it is constructed according to the use from the beginning, there is a problem in terms of manufacturing efficiency. In other words, the self-propelled trolley was constructed for the speed sprayer from the beginning, so that the trolley cannot be shared for other work vehicles, and the spraying direction of chemicals, water, etc. is also the traveling direction. It was specified on both sides and above, and it was difficult to spray chemicals, fertilizers, water, etc. on the ground crops and in areas where travel was impossible.

The present invention has been made in view of the above circumstances, and the self-propelled carriage can be shared with a speed sprayer and the like, and therefore can be used for various purposes, so that production efficiency can be improved and further maintenance can be performed. It is an object of the present invention to provide a liquid spraying work vehicle capable of facilitating operation and diversifying applications.

[0005]

[Means to try to solve the problem]

 To achieve the above object, the present invention has a chassis extended to the rear of a self-propelled vehicle equipped with a liquid tank, and has a hand-held spray nozzle at the tip on the extended chassis. It is configured such that a hose reel around which a hose is wound, a boom spray nozzle device, and a hose reel frame unit equipped with a water spray nozzle are detachably mounted.

[0006]

[Action]

 In the liquid spraying work vehicle of the present invention, as described above, the chassis 5 is extended to the rear part of the self-propelled carriage 1, and the extended chassis 5 has nozzles according to various applications required. The hose reel frame unit 11 carrying the is mounted and is detachably fixed with bolts, nuts and the like.

That is, since the chassis 5 portion is not directly machined to be provided with a nozzle device or the like according to various uses, the chassis 5 portion is not deformed and the hose is further deformed. Since the reel frame unit 11 can be manufactured in another factory or the like different from the manufacturing of the self-propelled carriage 1, the manufacturing efficiency can be improved.

Further, the self-propelled carriage 1 and the hose reel frame unit 11 can be removed, and maintenance and maintenance are easy, and the self-propelled carriage 1 includes the speed sprayer and other components. It can be used for various purposes.

In the present invention, a chemical solution, water or the like is supplied to the hand-held spray nozzle 6, the boom spray nozzle device 9 and the water spray nozzle 10 according to the place of use and the like and used. That is, the boom spray nozzle device 9 or the water spray nozzle 10 is used in a wide field or a golf course, and the hose 7 of the hand-held spray nozzle 6 is used in a place where the self-propelled carriage 1 cannot travel. -Used by pulling out from the reel 8.

[0010]

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings. The self-propelled carriage 1 comprises a driver's seat 2, a liquid tank 3 and an engine room 4 from the front part, and in the present invention, a chassis 5 is extended to the rear part.

The self-propelled carriage 1 can be easily obtained by removing the axial blower portion arranged at the rear end of the self-propelled speed sprayer. Further, on the extended chassis part 5, a hose reel 8 around which a hose 7 having a hand-held spray nozzle 6 is wound, a boom spray nozzle device 9 and a spray nozzle. A hose reel frame unit 11 integrally provided with 10 and the like is detachably mounted and fixed using bolts, nuts and the like.

That is, in the embodiment shown in the drawings, the hose reel frame unit 11 has a substantially U-shaped side surface, and a hose 7 having a hand-held spray nozzle 6 at the tip is wound inside the hose-frame. -Rule 8 is rotatably supported. The hand-held spray nozzle 6 is inserted into the housing cylinder 6a of the hose reel unit 11 when not in use.

Further, at the inner end of the support shaft 12 of the hose reel 8, the discharge side of a liquid pump (not shown) provided in the engine room 4 is a switching valve and a swivel joint (not shown). ), The inside of the support shaft 12 of the hose reel 8 and the inner end of the hose 7 are connected, and the hose 7 can be freely pulled out and wound up. ing.

The hose reel 8 is wound up by decelerating the rotation of an engine (not shown) in the engine room 4. That is, specifically, the V-belt 15 is loosely stretched in advance between the pulley 13 provided by decelerating from the output shaft of the engine and the pulley 14 provided on the support shaft 12 of the hose reel 8. , A tension pulley (not shown) is pressed against the V-belt 15 from the outside by a petal operation or the like to tension the V-belt 15, and the engine rotation is integrated with the pulley 14 and the pulley 14. The hose 7 is transmitted to the hose reel 8 and the hose 7 is rotated to automatically wind the hose 7 if necessary.

The hose reel frame unit 11 is pressed against the outer circumference of the hose reel 8 by the force of a spring, and can be released when the hose 7 is wound or pulled out. A breakable pad 16 is provided so that the hose reel 8 does not rotate naturally at all times.

Further, the hose reel frame unit 11 is provided with a boom distribution nozzle device 9. In the embodiment shown in the drawings, a central boom 18 having a large number of spraying nozzles 17 is provided at the lower end of the rear portion of the hose reel frame unit 11 so that extension portions 18a and 18b at both ends thereof can be folded upward. It is configured.

In the folding structure, the both end extensions 18a and 18b of the central boom 18 are appropriately hinged, and the folded state is always maintained upward by the tensile force of the spring 19. At the time of use, the spring 19 is tilted horizontally against the tensile force of the spring 19 and is kept horizontal by a lock device (not shown).

Further, the boom 18 and the extension portions 18a and 18b at both ends thereof are respectively hose-connected from the liquid pump provided in the engine room 4 through a switching valve (not shown). 20 are connected. Reference numeral 21 in the figure denotes a caster-type support wheel that travels while supporting both end extension portions 18a and 18b when the both end extension portions 18a and 18b of the boom are used.

At the center of the rear surface of the hose reel frame unit 11, a water spray nozzle 10 for horizontally spraying a liquid is attached in a positionally variable manner.

According to the present invention, as described above, the hose rail frame unit 11 equipped with the nozzles according to various uses is mounted on the chassis 5 which is extended to the rear of the self-propelled carriage 1 by means of bolts, nuts and the like. It is detachably fixed and completed.
