Description

DETAILED DESCRIPTION OF THE INVENTION (1) Object of the Invention [Field of Industrial Application] The present invention relates to bucket-type containers, and in particular to large bucket-type containers used for transporting and discharging liquids or bulk materials. It is related to.

[Prior Art] Conventionally, this type of bucket-type container has been used in the field of pollution elimination activities, such as extinguishing wide-area fires or protecting water quality.
It was often used by being suspended from a crane (also simply called a "helicopter"). Therefore, this type of bucket-shaped container is filled with materials such as fire extinguishing water or sawdust that have been appropriately treated with an oil binder at a filling station, and then transported by helicopter.
The container was suspended from a container and transported to a desired destination, whereupon the contents were quickly discharged and returned to the filling station in a short period of time, where it was once again used for filling and storage.

West German Patent No. 2,628,251 discloses a bucket-covered container that is provided with a closing member that fits into and closes a lower end opening or outlet of a cylindrical container body. . An operating lever connected to the center of the closing member extends upward and is slidably guided around the axis of the container body. The container body is moved relative to the closure member when the upper end of the operating rod is suspended from the crane of the helicopter. This bucket-type container is connected to the container body and is rolled up by a capstan winch of a helicopter in order to move the closing member and the container body relative to each other so as to open and close the lower end opening of the container body, that is, the discharge port. A rope that can be controlled is provided as a remote control means.

West German Patent No. 922,518 also discloses another bucket-type container containing a conical valve for opening and closing a lower end opening or outlet which is sloped downwardly and inwardly into the container body. ing. The conical valve includes an upwardly extending hollow valve rod that is suspended from a crane. This allows the bucket-shaped container to open its outlet when resting on the container body or support, and to move the conical valve downstream of the outlet. The valve rod is lowered further.

[Problems to be Solved] However, in conventional bucket-type containers, the relative movement between the opening at the upper end of the container body and the closing member is slow, and it is difficult to quickly release the stored items and, therefore, to quickly release the stored items. There were some drawbacks that made it unsuitable for transportation.

Therefore, in order to eliminate this drawback, the present invention provides a system for transporting or discharging fluids or valve materials by speeding up the filling and discharging operations of contained materials during wide area fire extinguishing activities or pollution elimination activities using a transport helicopter. The purpose of this project is to provide a bucket-shaped container.

[Function] The bucket-type container according to the present invention includes a pneumatic double-acting pressure cylinder that communicates with a pressurized air source disposed in the container, and has a piston on one side or the other side of the double-acting pressure cylinder. moving the container body relative to the closing member so as to open and close the outlet of the container with the container body connected to the operating rod or the piston rod of the piston by means of a remote control provided by supplying pressurized air from a pressurized air source; In addition, it has the effect of increasing the containment capacity of objects to the limit of the transport capacity of helicopters, as well as in low places such as near sea level, as well as in high places such as mountainous areas. It functions to make the discharge operation of the contained object flexible up to the transport height and transport speed, and also functions to expand the specific gravity of the contained liquid or bulk material.

[Examples] Next, the present invention will be specifically described by way of examples with reference to the accompanying drawings.

FIG. 1 is a sectional view showing a closed state of an embodiment of the bucket-type container according to the present invention, in which the closing member is directed toward the upper end opening of the container body l for transporting or filling objects. It was closed by being pulled up.

FIG. 2 is a sectional view showing an open state of the embodiment of the present invention shown in FIG. As a result, the lower end opening is slightly opened.

FIG. 3 is a cross-sectional view showing another open state of the embodiment of the present invention shown in FIG. Due to the separation, the lower end opening of the container body 1 is wide open. Further, in FIG. 3, blowing means is additionally provided to promote discharge of the contained material.

The fourth section is a plan view showing an embodiment of the present invention corresponding to diagram t53.

The bucket-type container of the present invention includes a container body l formed by a conical wall inclined downward and outward. The container body l has an opening at its lower end, that is, a discharge port (not shown) for the contained material (not shown).
A "lower end opening" (hereinafter referred to as a "lower end opening") is formed, and can be closed by relatively moving the closing member 2. One end of an operating rod 3 is connected to the center of the closing member 2 so that it can move relative to the container body l. The operating rod 3 is formed of a pipe or tubular body, and is guided in the central axis direction by an upper guide bush 5 and a lower guide bush 6 of the guide vibe 4. The guide vibe 4 is connected to the center of the cover member 8 and fixed on the central axis of the container body 1 by four supports 9 forming a spider type support. At least one (for example, four) filling holes 7 are formed in the cover member 8 for filling with objects. The filling hole 7 has a screen type (i.e. box type)
A lid lO is screwed on as desired. Operation rod 3 is
It is inserted into the center opening of the cover member 8 so that the lower end opening of the container body 1 can be closed by the closing member 2 by pulling it upward from the container body 1. Between the lower end opening of the container body l and the closing member 2, a sealing member such as a lip seal or a flat backing (see Fig. (not shown) or installed. One end of a lifting lobe 11 is attached to the upper end of the operating rod 3, allowing the bucket-type container of the present invention to be suspended from a crane. The other end of the lifting rope II is used, for example, in extinguishing fires in large areas using extinguishing water or sawdust, suitably treated with an oil binder, or in pollution abatement operations over large areas to protect wood. Powerful lift helicopter (hereinafter referred to as
It extends to a capstan winch (not shown) of a helicopter (also simply referred to as a "helicopter").

A conical scattering member I2 is disposed on the closing member 2 in order to enable good scattering of the contained objects when they are discharged from the lower end opening of the container body l. The top of the scattering member 12 is positioned upward and close to the circumferential surface of the operating rod 3 (preferably connected to the operating rod 3), and the bottom is in contact with the closing member 2. The scattering member 12 is designed to form an acute scattering angle when the closing member 2 is separated from the lower end opening of the container body 1 by the operating rod 3 (see FIG. 2 Σ and FIG. 3). .

When the bucket type container of the present invention is used for transporting bulk or lumpy materials.

The scattering angle of the scattering member 12 is set to facilitate the ejection action of the bulk material. In other words, when the rj4 button member 2 is moved relative to the container body l from the position shown in FIG. 1 (referred to as the "closed position"), the lower end opening of the container body l is opened. By cooperating with the periphery of the opening at the lower end of the container body l, the scattering range of the contained objects is expanded (see FIGS. 1 to 3).

The bucket-type container of the present invention is equipped with a pneumatic double-acting pressure cylinder 13 in order to be able to perform opening and closing operations by remote control, and a pressurized air source 14 disposed in the container body l. is communicated to. The double acting pressure cylinder 13 is.

Such a tandem is preferably capable of tandem movement so as to ensure two different positions (referred to as "open position 21") shown in FIGS. 2 and 3, respectively, relative to the closed position shown in FIG. To ensure operation, the double-acting pressure cylinder 13 is connected to the cover part 8 of the container body 1.
In contrast, a first piston 15 includes a piston rod 16 connected at one end, and a second piston 18 includes a piston rod 18 connected at one end to a bracket 19 disposed on the operating rod 3. and a piston 17. The double-acting pressure cylinder 13 therefore has two piston rods 16 between the operating rod 3 of the closure member 2 and the container body l.
．． 18, and pressurized air is supplied from a pressurized air source 14 to the two spaces or internal spaces of the double-acting pressure cylinder 13 having the first and second pistons Is and 17. At this time, the closure member 2 can be moved relative to the container body l. The supply of pressurized air to the double-acting pressure cylinder 13 is carried out via two control valves 20.21. Control valve 20.
21 are operated independently of each other by a remote control line 22 extending from one end to the helicopter. The control valves 20 , 21 are in communication both with the source of pressurized air 14 and with the two spaces or interior spaces of the double-acting pressure cylinder 13 . The double-acting pressure cylinder 13 is thereby communicated with a control valve 20.21 on each side of the piston Is, 17 arranged in its space or interior space. Corresponding to the first control position of the control valve 20.21, the piston 15.17 is therefore pressurized on one side and at the same time depressurized on the other side. Corresponding to the second control position l of the control valve 20.21, the piston Is,
17 is depressurized on one side and pressurized on the other side. The lower end opening and closing member 2 of the container body l shown in FIG.
(i.e., the open position of the closing member 2 relative to the lower end opening of the container body l - this is referred to as the "first open position") is achieved by operating only the control valve 20. . Also, the open state between the lower end frontage of the container body l and the closing member 2 shown in FIG.
J? The open position of the H material 2 (hereinafter referred to as the ":52 open position t") is achieved by operating the control valve 20 and the control valve 21 together. Incidentally, the open state between the lower end opening of the container body 1 and the closing member 2 shown in FIG. 3 may be achieved by operating only the control valve 21.

When the piston 17 is pressurized and the piston rod 18 is extended, the closing member 2 is brought to the second open position with respect to the lower end opening of the container body l, and the scattering member 12 is located at the most opposite to the lower end of the container body l. It has been moved to a lower position, that is, to a position that is most spaced apart. As a result, the bucket-type container of the present invention maximizes its opening width, thereby allowing the contained material to be quickly released. In this case, a rapid ejection operation can be ensured by additionally disposing a blowing means and operating it in conjunction with the relative movement of the closing member 2 with respect to the opening at the lower end of the container body 1 (see FIG. 3). As shown in FIG. 3, the blowing means communicates with another control valve 23 which is communicated with the pressurized air 11X14 similarly to the control valve 20.21, and with the control valve 23 via an air supply pipe 24. Two blowout nozzles 25
and can be remotely controlled via a control valve 23.

When the bucket-type container of the present invention is in a closed state, that is, in a state in which the lower end opening of the container body l is closed by the closing member 2 (see FIG. 1), for example, the bulk material is unraveled and separated; Alternatively, pressurized air may be blown out from the blowing nozzle 25 in order to sufficiently mix the plurality of components. As a result, the bucket-type container of the present invention improves the handling characteristics of the contents.

(3) Effects of the Invention As is clear from the above description, the bucket-type container according to the present invention is a bucket-type container for transporting and discharging liquid or bulk material, and includes (a) a discharge port formed at the lower end; (b) a closing member that closes the discharge port by fitting when moved relative to the content body;

(c) is attached to the center of the closure member and extends upwardly so as to be slidably guided by the guide means of the container body, and when suspended from a crane, the container is transported by a means of transport; (d) said outlet being in communication with a source of pressurized air disposed in the container and when pressurized air is supplied from said source for pressurizing one side or the other side; comprising a pneumatic double-acting pressure cylinder comprising a first piston having a first piston rod respectively connected to the operating rod and the container body for opening and closing; and a remote control means for moving the container body relative to the closing member, so that (i) helicopter transportation can be carried out in high places such as mountainous areas as well as in low places such as near sea level; It has the effect of improving the degree of containment of the contained object to the limit of force, and (i) has the effect of making it possible to release the contained object even at the height and speed of transportation by helicopter, and furthermore (iii) It also has the effect of expanding the specific gravity of the fluid or bulk material to be accommodated.
