Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a liquid dispersion device, and more particularly, to a liquid dispersion device equipped with an arrangement device for winding hoses around a winding drum.

(Prior art) Conventionally, as described in the 1986 edition product guide pages 22 to 23 published by Maruyama Seisakusho Co., Ltd., this type of device has a liquid tank installed on the front side of the frame supported by the hydraulic three-point link of the tractor. and a pump device operated by power from a drive source,
A winding device consisting of a winding drum and a winding stand, which are rotated by power from the drive source, is supported on the front side of the frame so that the axis of the drum is oriented in the front-rear direction. The hose to be wound on the drum can be pulled out from both the left and right sides and from the rear, and the winding operation can be performed, and at the upper end of the winding stand, a support stand is provided that protrudes upward from the outer peripheral edge of the drum. An alignment device having a hose guide for guiding the hose in the axial direction of the drum is provided at the upper end of the support base, and when the drum rotates, the hose guide in the alignment device is reciprocated in the front-rear direction with respect to the drum. It is known that he has succeeded in doing so.

(Problem to be Solved by the Invention) However, in this conventional spraying device, the alignment device is unchangeably positioned above the outer periphery of the drum, and the hose guide is aligned in the longitudinal direction with respect to the drum. Therefore, as shown in FIG. 5, for example, the winding device M is disposed above the liquid tank C to shorten the length of the spraying device in the front and rear direction, and the spraying device If the center of gravity of the vehicle is shifted to the front side so that the vehicle can be mounted on a small tractor with a relatively small hydraulic three-point linkage, the following problems arise.

That is, in this case, the height above the ground of the alignment device S provided above the drum is too high than the height of the worker, so when the hose is pulled out and wound up behind the spraying device, the When the hose guide G of the alignment device S moves in the front-rear direction with respect to the drum D, the hose H guided by the hose guide G connects to the outer periphery of the winding drum D or a support base that supports the alignment device. As a result, the drawer of the hose H,
There is a problem that the winding operation becomes extremely difficult.

By the way, in order to solve this problem, it is possible to lower the height of the alignment device from the ground by arranging the alignment device on the side of the winding device. There is a problem in that it becomes impossible to perform drawer and winding operations from both the right and left sides of the dispersion device.

In order to solve this problem, the alignment device may be provided on both the left and right sides of the winding device, or the winding device may be structured so that it can swing relative to the frame. Both have complicated structures and high costs.

The purpose of the present invention is to make it possible to lower the alignment device to the height of the axis of the winding drum, while also allowing the winding device to be disposed above the liquid tank so that the length of the spraying device in the front and back direction can be lowered. Even in the case where the center of gravity of the spraying device is shortened and the center of gravity of the spraying device is shifted to the front side, by rotating the alignment device, the pulling out and winding operations of the hose can be performed on both left and right sides of the spraying device, and When the hose is operated at the rear of the spraying device, even when the hose guide moves to the front side, the hose can be easily pulled out and the winding operation can be performed without interfering with the outer periphery of the winding drum. It is something to do.

The chain 55 is provided with an elongated guide groove 57 extending in a direction perpendicular to the direction of movement of the chain 55. An engaging body 58 is provided in the section, and this engaging body 58 is engaged with the inner surface in the width direction of the guide groove 57 of the slide body 56, and the rotation movement of the chain 55 causes the slide body 56 to be attached to the rail 52. Along with moving along the
During rotational movement of the chain 55, when the engaging body 58 reaches the upper or lower position on the vertical line While the engaging body 5 rotates by a length of
8 along the guide groove 57 from an upper position on the vertical line X to a lower position on the line X, or from a lower position on the vertical line X to an upper position on the line The moving direction of the slide body 56 that moves together with the slide body 58 is rotated, and this slide body 5
While the moving direction of the drum 41 is changed, the drum 41
The hose H that has been spirally wound up and has reached one end of the drum 41 is attached to one end of the drum 41.
In addition to winding the hose H in a heavy manner, the winding direction of the hose H is changed.

The hose guide 51 is made to protrude to one side in the vertical direction with respect to the rail 52, and includes a support body 51a attached to the slide body 56, and a pair of rollers 51b rotatably supported by the support body 51a. , 51b, and these rollers 51
