[Structure] A belt conveyor 1 equipped with belt drive shafts 6 and 7 with a head belt wheel 3 and tail bells 4 at both ends of a frame 2, and belt drive shafts 6 and 7, a power unit 14 or a motion conversion device 16 and a belt drive. It is composed of a flexible shaft 12 connecting the shafts 6 and 7, and is characterized by being integrated in a remote control manner. [Effect] If there is a rotating part or a slide in equipment such as a press without using a motor or an engine, it can be used as a belt conveyor in a lightweight, small size and easily installed and used anywhere. In addition, since a remote control system using a flexible shaft is used without using the motor main shaft, it is possible to provide a very simple and compact portable belt conveyor at low cost and at low cost.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a portable small belt conveyor.

[0002]

[Prior art]

 Portable small belt conveyors are extremely widely used today in the fields of press, machining and construction and civil engineering, and they are indispensable machines for short-distance transportation and inclined transportation. Not only is it used for various purposes, such as loading and unloading earth and sand, rooting underground works, and carrying out earth and sand from a narrow underground work site by connecting several units, it is also used as a cargo handling machine for warehouses, premises, etc. But many are used.

[0003]

[Problems to be solved by the device]

 However, in the conventional belt conveyor, the drive roller is directly connected or decelerated and used by rotating it with the motor engine, and it is inevitable that it will be structurally troublesome, and it is light and small, and it is narrow. It was difficult to use the equipment easily in the space. The present invention has been made to solve the above problems, and an object of the present invention is to provide a portable compact belt conveyor that is lightweight, compact, and easily mounted anywhere without using a motor or engine.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and its gist is to provide a belt conveyor having a belt drive shaft with endless belts stretched between head belt wheels and tail belt wheels at both ends of the frame. It is a portable small belt conveyor that is characterized by a flexible shaft that connects a power unit or motion conversion device and a belt drive shaft, and is integrated in a remote control manner. The present invention will now be described in detail with reference to the following embodiments with reference to the drawings.

[0005]

【Example】

 First, 1 is a belt conveyor having an endless belt 5 between a head belt wheel 3 and a tail belt wheel 4 at both ends of a frame 2 and belt drive shafts 6 and 7. Reference numeral 12 is a flexible shaft that connects the power unit 14 or the motion conversion device 16 and the belt drive shafts 6 and 7. In addition, 3a and 4a are shafts of the head belt wheel 3 and the tail belt wheel 4, and 8 and 9 are bevel gears and 10 and 11 are gears. Further, the present invention is characterized by comprising the power unit 14 or the motion converting device 16 and the flexible shaft 12 connecting the belt drive shafts 6 and 7 as described above, and integrating them in a remote control manner. It is a portable small belt conveyor. As the power unit 14, for example, a motor (electric or hydraulic) or an engine can be used. As the motion conversion device 16, a device using a wire winding mechanism 22 using a one-way clutch (one-way clutch) 19 as shown in FIGS. 4 and 5 can be used. That is, in this structure, the wire 17 whose upper end is attached to the elevating ram of the press 15 moves downwardly around the wire adjusting wheel 18 having the one-way clutch 19 and is wound up, so that the clutch enters and the wire 17 moves up and down. Directional motion is converted to rotational motion. Further, as the motion converting device 16, it is also possible to use a rack including a lifting rack 21 using a one-way clutch 19 and a pinion 20 and a pinion mechanism 23 as shown in FIG. In FIG. 3, 13 is a set screw for connecting one end of the flexible shaft 12 to the belt drive shaft 6 to integrate them. In the case of belt conveyors, the compactness and compactness of the products and scraps that are conveyed on the belts prevent them from getting inside the belts, and they get caught between the belts and rollers, causing troubles inside the mechanism. It is easy to get up. This belt conveyor is a simple and compact belt conveyor equipped with a falling mechanism at the conveyor tip and a flexible shaft for the drive unit.

[0006]

[Effect of device]

 In the present invention, since the motion conversion device 16 and the flexible shaft 12 are integrated into one unit, if there is a rotating part in equipment such as a press without using a motor or engine, it can be used. As a belt conveyor, it is lightweight and small, and it can be easily installed and used anywhere, which is convenient for the user. In addition, in the present invention, a so-called remote control remote control system is adopted in which the main shaft of the motor is not used but a flexible shaft is used.Therefore, only the belt conveyor is provided in the working part, and the flexible shaft is used in the rotary power part such as the motor. We can provide a very simple and compact portable belt conveyor at a low cost and at a low price.
