Patent No. 4901251 Japanese Patent Application Publication No. 2003-93938

In the conventional hose winding device described above, the hose reel or bobbin is rotatable and fixed/locked at a certain predetermined angle. In the device described in Patent Document 1, the hose reel can be fixed at any use position, but the number of angles that can be selected is limited. In the device described in Patent Document 2, it is stated that the rotation angle of the bobbin is arbitrary, but the positions where the bobbin can be locked are limited to limited positions (storage state). When attempting to spray a chemical solution using a hose, it is difficult to stop the vehicle body of the speed sprayer so as to match the desired direction of feeding the hose. Even if the hose reel can be fixed at multiple angles as in the conventional technology, there is a limit to the range of angles that can be accommodated. If the rotating position of the reel can be adjusted and fixed steplessly, the rotating position of the reel can be finely adjusted to match the desired payout direction, no matter what direction the vehicle is stopped.

Can be loosened. For example, as shown in FIGS. 1 and 5, the handle portion 26b is arranged to extend in front of the shaft portion 26a, the horizontal plate portion 21c is tightened, and the reel support portion 23 is fixed.

The lever 26 provided on the base plate 21 can fix the reel support part 23 by rotating the handle part 26b when the reel support part 23 is located at an arbitrary rotation position. An operation space S is formed between the bottom plate portion 30, the reel 15, and the pair of upright support portions 35, 36, for the operator to grasp and operate the handle portion 26b of the lever 26. A handle portion 26b is arranged within the space S. The operation space S is open toward the side (left side) of the vehicle body 1 at the storage position P1 of the reel 15 shown in FIG. 1 (see FIG. 1). The operation space S is formed so that a hand can be inserted between the handle portion 26b and the hose 40 even when the hose 40 is wound around the reel 15 (see FIG. 3). With the above configuration, the operator can easily access the operation space S and the handle portion 26b arranged within the operation space S by extending his/her hand.

The speed sprayer 100 configured as described above is driven by the engine, and the spray pump is operated by the engine to supply the chemical liquid in the chemical liquid tank 5 to the spray nozzle 10 of the nozzle head 7. It is sprayed from 10. At the same time, the blower 8 is operated by the engine, and air is sucked in from the rear by the blower 8, and the air flow is ejected radially outward from the periphery of the spray nozzle 10, so that the sprayed chemical solution is It is spread around the vehicle body, and the chemical solution is suitably dispersed.

When spraying a chemical solution in a narrow place where the speed sprayer 100 cannot run, the driver (operator) stops the speed sprayer 100 and closes the valve on the spray nozzle 10 side to allow the spray nozzle 10 to Get off the driver's seat 11 with the spraying stopped. The driver standing in the field operates the lever 26 to rotate the reel 15 and the reel support part 23 to a desired position (angle), and holds and fixes the reel support part 23. The hose 40 wound around the reel 15 of the hose winder 14 is held and let out by hand, and the valve on the hose winder 14 side is opened to spray the chemical solution to a desired location. Since the hose retractor 14 is disposed near the peripheral edge 1a of the vehicle body 1, the hose 40 can be unreeled without any problem. The hose 40 may be let out with the lever 26 loosened, and the reel 15 and the reel support part 23 may be rotated to their natural positions (angles) by this feeding.

According to the hose winder 14 of the present embodiment, the reel support section 23 including the bottom plate section 30 is guided by the elongated hole 29 and is guided by the elongated hole 29 to a predetermined position as the shaft section 26a moves relatively within the elongated hole 29. Rotate the angle range. By operating the lever 26 including the shaft portion 26a, the reel support portion 23 can be fixed on the base plate 21 when the reel support portion 23 is located at an arbitrary rotational position. Therefore, the rotational position of the reel 15 can be adjusted and fixed steplessly (see FIG. 6). Thereby, no matter what direction the vehicle body 1 of the speed sprayer 100 is stopped, the rotational position of the reel 15 can be finely adjusted to match the desired feeding direction. The desired feeding direction is a direction perpendicular to the axis of rotation of the shaft portion 15b of the reel 15.

With conventional hose retractors, for example, knob bolts may need to be loosened or fixed with pins. Therefore, the work of fixing and releasing the reel was complicated and required strong force. According to the hose winder 14 of this embodiment, the reel 15 can be fixed and released using the lever 26, so the work is simple and the required force is small.

The reel support part 23 includes a pair of upright support parts 35 and 36 that are provided to stand up from the bottom plate part 30 and support both ends 15a of the reel 15 at a position higher than the bottom plate part 30, and the bottom plate part 30 and the reel 15 A handle portion 26b of the lever 26 is disposed therebetween, and an operation space S is formed in which the handle portion 26b can be operated. Therefore, the operator can stand on the side of the hose winder 14, put his hand into the operation space S, and grasp the handle portion 26b of the lever 26. Therefore, the reel 15 and the reel support part 23 can be easily fixed or unfixed.

The rotation fulcrum 22 includes a bolt 27a inserted through the bottom plate 30 and the base plate 21, and a disc spring 28 interposed between the bolt 27a and the bottom plate 30 or the base plate 21. Therefore, by appropriately adjusting the tightness of the bolts 27a, the bottom plate portion 30 can slide with respect to the base plate 21 with a certain resistance. It is possible to prevent the reel support part 23 from rotating too easily, and the rotational positions of the reel 15 and the reel support part 23 can be easily adjusted.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, an arcuate long hole may be formed in the base plate 21, and a lever for fixing the reel support part 23 may be provided in the bottom plate part 30 of the reel support part 23. The handle part 26b of the lever 26 is not limited to the case where it is arranged in the operation space S between the bottom plate part 30 and the reel 15, but can be formed between the base plate 21 and the mounting surface of the vehicle body 1 such as the fender 9. It may be arranged in a space (a space below the mating surface of the base plate 21 and the reel support part 23).
