Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a hose winding device equipped as an auxiliary spreader or the like in a speed sprayer or the like, and more specifically to a hose winding device capable of reducing the space for taking in and out. It relates to the device.

[Conventional technology]

Large-scale self-propelled control machines such as speed sprayers are equipped with auxiliary sprayers in order to appropriately perform spraying that cannot be covered by the main sprayer. The hose winding machine of the auxiliary sprayer is normally retracted and stored inward from the side edge of the machine base so as not to hinder the running of the speed sprayer etc. In order to smoothly extend and retract, it is located at a position protruding outward from the side edge of the machine base.

FIG. 4 is a plan view of a conventional hose winding device that can be freely taken in and out (eg, Japanese Utility Model Laid-Open No. 63-160968). The same components as those of the embodiment of the present invention described later are designated by the same reference numerals, and the description will be omitted and the main points will be described. Swivel stand 40
Is a rectangular sliding plate portion 44 that rotates and slides on the surface of the machine base 12 around a vertical axis passing through the connecting pin 42, and a lower end portion of the sliding plate portion 44 is fixed to the sliding plate portion 44. The hose winding wheel 24 is rotatably supported at one end by the upper end portion of the stand portion 46. Then, when not in use, the sliding plate portion 44 is locked to the machine base 12 in a direction substantially perpendicular to the side edge 14, and the hose winding wheel 24 is drawn into the inside of the side edge 14, Further, at the time of auxiliary spraying, the sliding plate portion 44 is locked to the machine base 12 so as to substantially follow the side edge 14, and the hose winding 24
Are projected to the outside of the side edge 14.

In addition, Japanese Utility Model Publication No. 60-22035 discloses a structure for taking in and out a winding vehicle for a digestion hose, which is stored so that its axial direction is at a right angle to the side edge of the opening / closing opening and is in use. Then, it is linearly moved in the axial direction and pulled out from the loading / unloading opening.

[Problems to be solved by the device]

 The problems with the hose retractor of FIG. 4 are as follows.

(A) Since the hose winding wheel 24 is rotated around the coupling pin 42 to be taken in and out of the side edge 14, the necessary width for taking in and out is about the sliding plate. The connecting pin 42 of the portion 44 has a dimension L2 between the edge of the ring and the portion of the side frame 28 that is most distant from the connecting pin 42 in the horizontal direction, which is a large value.

(B) When using the auxiliary spreader, attach the hose winding 24 to the side edge 14
In order to completely extend it to the outside of the hose, the position of the coupling pin 42 should be sufficiently separated from the hose winding 24 in the axial direction of the hose winding 24,
It must be outside the side edge 14, which further increases the withdrawal width and creates protrusions.

(C) In order to hold the hose winding wheel 24 in the projecting position and the retracted position, it is necessary to insert the locking pins into the locking holes of the machine base 12 one by one.

In Japanese Utility Model Publication No. 60-22035 as well, the hose winding wheel is held in the axial direction at a right angle to the side edge of the loading / unloading opening and is loaded / unloaded. , Becomes a large value. Moreover, in Japanese Utility Model Publication No. 60-22035, there is no particular locking mechanism for holding the hose winding wheel in the retracted position, and the hose winding wheel easily moves due to vibration or the like.

Further, in both the hose winding device of FIG. 4 and Japanese Utility Model Publication No. 60-22035, there is no means for restraining the rotation of the hose winding at the time of storage, and the hose may come loose.

The object of the present invention is to reduce the width of loading and unloading of the hose winding wheel, to save the trouble of locking the hose winding wheel to the projecting position and the storage position, and to omit the locking mechanism and simplify the displacement mechanism. It is possible to provide a hose winding device that can be used, and also to allow the hose winding wheel to be restrained from rotating in the retracted position with a simple structure.

[Means for Solving the Problems]

The invention will be described using the reference numerals of the drawings corresponding to the embodiments.

The hose retractor of this invention has the following components (a) to (c).

(A) A support arm (16) that is swingably supported by the machine base (12) around a straight line parallel to the edge line (14) of the machine base (12) (b) This support arm (16) The support arm (16), which is rotatably attached to the tip of the support arm (16) in parallel with the swing axis of the robot, projects outside the edge line (14) of the machine base (12) as the support arm (16) swings.

[Effect of device]

 The effects of this device are listed below.

(1) Since the hose winding machine is inserted and withdrawn inside and outside the edge line while keeping the axial direction parallel to the edge line of the machine stand, the width of the hose winding case required at the edge line is almost equal to the hose winding line. The width of the car can be set, and the width of putting in and out can be significantly reduced.

(2) At the retracted position and the protruding position of the hose winding wheel,
Since the hose winding wheel and the support arm are placed and pressed by the gravity of the hose winding wheel, etc. on the surface of the machine base, the locking operation for locking at each position can be omitted and the loading / unloading operation can be simplified. In addition, the special locking mechanism can be omitted.

(3) The hose winding vehicle can be taken in and out by swinging the support arm in a substantially vertical plane, and the displacement mechanism of the hose winding vehicle becomes simple.

(4) Since the hose winding wheel makes frictional contact with the friction material fixed to the machine base at the storage position with a predetermined weight and is restrained from rotating, it is possible to prevent the hose from coming loose from the hose winding wheel. It is also possible to omit special labor for restraining.
