Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a device for attaching and detaching a flexible screw conveyor, which is composed of a flexible tube and a coil-spring-shaped transfer rod mounted in the tube, to a tank or the like. It is a thing.

(Prior Art) Conventionally, as a structure in which a conveyed object receiving portion or a discharging portion of a flexible screw conveyor is detachably configured by including a transmission portion in a conveyed object passage such as a tank or a discharge box, a publicly known Japanese patent publication 45-
There is one described in Japanese Patent No. 33139, but in this technique, since the transfer rod and the tube are specially attached, the attachment / detachment operation thereof is complicated.

Further, in the technique disclosed in Japanese Utility Model Publication No. 46-362, since the bearing device and the connecting device of the flexible conveyor are located in the transfer passage, these members only hinder the transfer. In addition, dust or conveyed objects may enter the transmission member and cause troubles.

(Problems to be Solved by the Invention) This invention solves the above-mentioned drawbacks of the prior art,
An object of the present invention is to provide an attaching / detaching device of a flexible screw conveyor that can be easily attached / detached and can surely protect the transmission portion from intrusion of dust and the like.

(Means for Solving the Problems) The mounting tube 5 for mounting the conveyed material receiving section 2 or the discharging section 3 of the flexible screw conveyor 1 at the end of the tube 4, and the mounting tube 5
And a plurality of connecting rods 9 and 9 connecting between the mounting cylinder 5 and the bearing 8 and a bearing 8 which is located at a distance from each other and which receives the shaft 7 for attachment at the end of the transfer rod 6 in the form of a coil spring. In order to mount the receiving part 2 or the discharging part 3 in the conveyed article passage 12 such as the tank 10 or the discharge box 11, the tip of the bearing 8 is formed into a taper shape, and the taper is formed on the one side plate 13 of the conveyed article passage 12. A state in which a rectangular shaft portion 15 at the end of the shaft 7 protruding from the bearing 8 is attached to the outer side of the one side plate 13 and has a slightly interchangeable portion (l) in the axial direction The flexible screw conveyor attaching / detaching device is configured by being fitted together.

(Advantage of the Invention) When the conveyed material receiving portion 2 or the discharging portion 3 of the flexible screw conveyor 1 is mounted in the conveyed material passage 12 such as the tank 10 or the discharging box 11, the mounting tube attached to the end of the tube 4 is attached. 5 and a shaft 7 attached to the end of the transfer rod 6 at a distance from the mounting cylinder 5.
A bearing 8 is formed in a tapered shape on the receiving portion 2 or the discharging portion 3 which is integrally formed by connecting the receiving bearing 8 with the connecting rods 9 and 9. The rectangular shaft portion 15 at the end of the shaft 7 projecting from the bearing 8 is fitted to the cylindrical shaft 16 attached to the outside of the one side plate 13 while being inserted into and supported by the guide hole 14 having a circular shape.
