Description

[Detailed Description of the Invention] This invention relates to a set power spraying machine with an automatic hose winder, which has a winding guide on the machine frame for aligning and winding the hose on a winding drum.

Figures 1 to 3 show a conventional set power sprayer with an automatic hose winder; Figure 1 is a front view, and Figure 2 is a front view;
The figure is a plan view, and Fig. 3 is a side view of the upper half. , 6 is a pipe connecting the winding drum 4 and the power sprayer 3, 7 is a drive pulley for the winding drum 4 protruding from the power sprayer 3, and 8 is a drive pulley 7 and a pulley 9 for the winding drum 4. 10 is a transmission clutch pedal that engages and disengages the tension roller 11 from the transmission belt 8 to switch between driving and stopping the winding drum 4; 12 is a winding guide for the water supply hose 5; The winding drum 4 is mounted so as to be freely movable on two parallel rails 13 horizontally suspended on the machine frame 1 above the winding drum 4. The power sprayer 3 is connected to a separate tank (not shown) and also has an outlet (not shown) communicating with the atmosphere. Further, the winding guide 12 is configured such that an upper pulley 12a portion thereof can pivot in the horizontal direction.

Now, when the transmission clutch pedal 10 is depressed as shown in FIG. is wound up in the direction of arrow 14. At that time, the water supply hose 5 is aligned on the winding drum 4 by manually reciprocating the winding guide 12 along the rail 13 over the entire width of the drum. In some cases, the winding guide 12 is automatically reciprocated on the rail 13 in accordance with the hose winding lead to the winding drum 4.

As described above, in the conventional set-power spraying machine with an automatic hose winder, the water supply hose 5 is directly connected to the winding guide 12, which manually or automatically reciprocates over the width of the winding drum on the rail 13 and winds the hose in an aligned manner. Since the weight and force of the water supply hose 5 is applied, especially when the feeding direction of the water supply hose 5 is right sideways as shown in the figure, the winding guide 1 is affected by the weight and force of the water supply hose 5 described above.
2 becomes difficult to move, which not only makes it impossible to wind the winding drum 4 in an aligned manner, but also leads to damage to the winding guide 12.

This idea was made in order to eliminate the above-mentioned drawbacks of the conventional set power sprayer with an automatic hose winder. A swingable arm is provided approximately on the center line of the drum width of the take-up drum, and the tip of which uses the vicinity of this hose guide as a fulcrum and makes a fan-shaped reciprocating motion in the horizontal direction above the take-up drum. By attaching a winding guide, the hose can be easily and reliably wound in line no matter which direction it is being fed out.In addition, the winding guide has a simple structure and is inexpensive.This set comes with an automatic hose winder. The purpose is to provide a power sprayer.

An embodiment of this invention will be described below with reference to FIGS. 4 to 6. In the figure, numerals 1 to 11 and 14 are the same as those in FIGS. 1 to 3. 15 is a hose guide provided on the machine frame 1 on the center line of the drum width away from the winding drum 4;
It is composed of a pedestal 15a mounted on the pedestal 15a, a portal shaft 15b erected on the pedestal 15a, and two pulleys 15c rotatably fitted on both left and right sides of the portal shaft 15b. 17 is an arm that is swingably attached to the machine frame 1 with a pin 18 so that its tip makes horizontal fan-shaped reciprocating motion above the winding drum 4; 19 is a winding guide that is attached to the tip of the arm 17; Support frame 19a fixed to arm 17 and this support frame 19a
It consists of a pulley 19c built around a horizontal shaft 19b. 20 is a handle for manual operation attached to the support frame 19a. Note that θ in the figure indicates the swing angle of the arm 17.

The water supply hose 5 being wound up in the direction of the arrow 14 passes between both pulleys 15c of the hose guide 15 and then enters the pulley 19c of the winding guide 19, so no matter which direction the water supply hose 5 is unwound, it will not wind up. The taking guide 19 must always be entered from the front.
At this time, by manually operating the handle 20 at the tip of the arm 17, the water supply hose 5 from the winding guide 19 is wound in an aligned manner onto the winding drum 4 by causing a fan-shaped reciprocating motion.

As described above, according to this invention, a hose guide located on the front side of the hose than the winding guide is provided approximately on the center line of the drum width of the winding drum away from the winding guide, and in the vicinity of this hose guide. By providing a swingable arm whose tip moves horizontally in a fan-shaped reciprocating motion above the winding drum with the hose as a fulcrum, and by attaching a winding guide to the end of this arm, the hose can be fed out in any direction. The hose always enters the take-up guide from the front, so when the hose is fed out sideways like in the past, the take-up guide may not move properly due to the influence of the weight and force of the hose. The smooth movement of the take-up guide allows for easy and reliable winding, and since the take-up guide only needs to be attached to the tip of the swinging arm, there is no need for a transition mechanism or a rotation mechanism for the take-up guide as in the past. Since the structure of the winding guide is simple and inexpensive, the winding guide has the advantage of being less expensive.

In the above embodiment, the hose guide 15 is fixed to the machine frame 1 with bolts 16, but as shown in FIG. The pedestal 1
A rotary hose guide 15A rotatably attached to the hose guide 5a may be used. In this case, the water supply hose can be fed even better. Incidentally, the pedestal 15a is of course bolted to the side surface of the machine frame 1.

In each of the above embodiments, there are two pulleys 15 on the left and right.
Hose guides 15 and 15 constituted by c.
A is shown, but as shown in FIG. 8, the fixed hose guide 1 is composed of four rotatable rollers 15e on the left, right, top and bottom and set on a pedestal 15a.
5B, or as shown in FIG. 9, the rotary table 15d
A rotary hose guide 15C may be used, which is constituted by four rotatable rollers 15e on the left, right, top and bottom.

In the above embodiment, the hose guides 15, 15
Although hose guides A, 15B, and 15C are all shown attached to the machine frame 1, the hose guide 15 may be attached to the arm 17 as shown in FIG. 10, and other hose guides 15A, 15B, and 15C are also shown. Although not, it is of course possible to attach it to the arm 17.
