[Conventional technology]

A multi-mouthed hose head is used to spread powder on rice fields, etc., and is made of flexible thin-walled material such as vinyl. One end of the hose is connected to a backpack power spreader, and the hose head is used to spray powder from the backpack power spreader. Ejects from each nozzle.

After the spraying work, the multi-nosed hose head is wound up on a winding machine and stored.
No. 63-76768) has a structure in which an operator manually turns a handle to wind up a multi-mouthed hose jet.

[The problem that the idea attempts to solve]

The problems with such conventional winding machines are as follows.

(a) Since the multi-mouthed hose head is long, reaching several tens of meters, the effort required to wind up the entire multi-mouthed hose head on a winder increases, causing a great deal of fatigue.

(b) Since winding is done manually, the winding speed is low and the time required for winding is long.

(c) The operator, while holding the winder with one hand,
It is necessary to turn the handle with the other hand and also untwist the multi-mouthed hose head that occurs during winding, which makes the work complicated and requires skill.

The purpose of this invention is to overcome the above problems and
To provide a winding machine for a hose jet head that can be driven by mechanical power and does not require a special power source.

The operation of the embodiment will be explained.

During the work of dispersing the powder 44, the end of the multi-mouthed hose head 32 is attached to the bellows tube outlet 52 of the bellows tube 30 and fixed with a band 50. As the blower 14 operates, the powder 44 is carried by the conveying air, is led out from the fan case outlet 48, is guided into the multi-nosed hose nozzle 32 through the bellows pipe 30, and is introduced into each nozzle of the multi-nosed hose nozzle 32. It is ejected and dispersed from 34.

After the spraying work is completed, remove the end of the multi-mouthed hose nozzle 32 from the bellows pipe outlet 52 of the bellows pipe 30, and attach the end to the axis 6 of the hose head winder 54.
0 through the elongated hole 62 to lock the multi-port hose jet head 32 to the shaft center 60. Further, the inlet 80 of the hose jet winder 54 is connected to the bellows pipe outlet 5 of the bellows pipe 30.
2 and fixed with a band 50, the blower 14 is driven while the shutter 42 is kept fully closed by the shutter lever 24. The wind generated in the blower 14 is introduced into the impeller chamber 70 from the fan case outlet 48 via the bellows pipe 30 and the inlet 80, rotates the impeller 72 in the impeller chamber 70, and is discharged from the outlet 82. The shaft center 60 rotates together with the impeller 72 as the impeller 72 rotates, and as a result, the multi-hole hose jet head 32 is wound around the shaft center 60 while becoming a thin plate. The operator grips the multi-hole hose head 32 being wound up while sliding it near the hose head winder 54, and untwists the multi-hole hose head 32 when it is twisted. When the operator applies a force equal to the winding force of the multi-hole hose head 32 by the axis 60 in the direction of pulling out the multi-hole hose head 32 from the hose head winder 54, the impeller 72
It stops rotating against the wind from 4. The rotational speed of the shaft center 60 during winding can be changed by operating the throttle lever 26 of the backpack power spreader 10 and adjusting the output of the engine 16, that is, the amount of air blown from the blower 14.

Note that, in addition to being driven by the wind from the blower 14, the hose jet winder 54 can wind up the multi-mouth hose head 32 by rotating the handle 64 manually, as in the past. is also possible.

[Effect of idea]

In this design, the winder is detachably attached to the inlet of the impeller chamber to the outlet of the power spreader, and uses the wind sent out from the power spreader as a power source to rotate the impeller, and Rotate the winding shaft. Therefore, the following effects can be obtained.

(a) Human power can be omitted in order to rotate the rotating shaft for winding the hose jet head, and
It is possible to omit the effort of operating the handle with one hand, and it is possible to reduce labor and winding time.

(b) The worker can concentrate on untwisting the hose head that is being wound around the rotating shaft, which streamlines the work of untwisting the hose head and allows the hose head to remain untwisted. It can reduce winding.

(c) The wind from the power spreader is used as the power source, and the rotating shaft is not directly connected to a drive source such as a motor, so when the worker stops the hose head during untwisting, etc. There is also no need to worry about damage to mechanical parts.

(d) Since the power spreader used with the hose jet is used as the power source, there is no need to add a special power source.
