BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powder feeder.

[0002]

2. Description of the Related Art Conventionally, a feeder unit and a drive unit of a granular material feeder are a pair and are fixed and used at a predetermined position. When switching bodies, it took time to clean the inside, and it was necessary to prepare drainage equipment for washing with water.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate time loss and to simplify equipment when switching between granules.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an inner cylinder for supplying powder and granules on a bottom plate through a gap, and an outer cylinder sharing a center line with the inner cylinder. The lower end is connected to the bottom plate, and an annular passage for the granular material discharged from the gap is formed between the inner and outer cylinders, a discharge port is provided in the passage, and the upright rotating body protrudes from the center of the bottom plate. A center rotating blade, an outer circumferential rotating ring provided along the inner circumferential surface of the outer cylinder at a tip of the rotating blade, a plurality of outer rotating blades provided on the rotating ring facing inward, and the upright rotating body is provided. A feeder unit provided with a rotating shaft below the bottom plate, and a drive unit for the rotating shaft provided on the machine frame, the drive unit and the feeder unit are detachably and independently provided, and the feeder unit is The powdery and granular material feeder, which is detachably supported on the machine frame and is portable, The granular material feeder according to the first or second aspect of the present invention, wherein a plurality of lifting rings are provided on the outer surface of the outer cylinder of the feeder portion, wherein the fork insertion support portion of the lift is provided at the lower portion of the bottom plate. The powdery and granular feeders according to the first to third aspects of the present invention are provided with guides for positioning the feeder section on the machine frame.

[0005]

According to the present invention, the granular material is filled in the inner cylinder of the feeder section separately mounted on the floor, lifted by a forklift or a crane, transported above the machine frame, and moved along the positioning guide. Then, the drive unit of the rotating shaft provided on the machine frame engages with the rotating shaft, and the feeder unit is fixed to the machine frame.

In this state, the drive unit is operated to rotate the rotating shaft, and the upright rotating body, the vehicle radial rotating blades, the outer peripheral rotating ring, and the small blades are rotated to form a repose angle of the granular material from the gap. And discharged into an annular passage, and can be discharged from the discharge port of the passage outside the machine.

After the work is completed, the feeder unit is lifted and separated from the machine frame and the drive unit by a forklift or a crane.
The feeder can be conveyed to the floor to clean and wash the feeder section, and to switch the granular material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An inner cylinder 2 for supplying powder and granules is provided on a bottom plate 6 with a gap t interposed therebetween. The gap t between the cylinders 1 and 2
An annular passage p for the granular material discharged from the container is formed, and a discharge port 20 is provided in the passage p.

At the center of the bottom plate 6, there is provided an upright rotating body c having a conical upper end, and the radially rotating blades 3 are provided thereon.
An outer peripheral rotating ring 5 is provided at the tip of the rotating blade 3 along the inner peripheral surface of the outer cylinder 1, and the rotating ring 5 has a plurality of small outer rotating blades 4 facing inward. The rotating shaft 7 of the upright rotating body c is provided downward at the lower portion of the bottom plate 6, a downward engaging clutch 8 is provided at the lower end of the rotating shaft 7, and the toggle clamp 16 and the plunger 15 ( 3), the ring 5 is stopped at a fixed position, and accordingly, the rotation stop position of the downward meshing clutch 8 is positioned to form the feeder portion f of the granular material.

As shown in FIG. 3, fork insertion support portions 11 and 11 and support legs 9 and 9 made of downward channel steel are provided at the lower portion of the bottom plate 6, and a crane lifting device is provided on the outer surface of the outer cylinder 1. At least three rings r are provided.

On the other hand, the machine frame 21 provided on the floor surface has
9 are provided with mounting portions 9 ', 9' and guide inclined plates 10, 10 for the mounting portions 9 ', 9' to form guides 22, 22 for positioning the feeder portion f. Flex coupling 1 on the upright output shaft 23 of the motor 13
7 is provided at the upper end of the output shaft 23.
Are provided to form the driving section d.

The upward meshing clutch 8 can be stopped at a meshing position with the downward meshing clutch 8 by a fixed position stopping device provided by a positioning sensor 18 provided on the machine frame and a sensor dog 19.

Reference numeral 24 in the drawing denotes a bearing housing, and reference numeral 25 denotes a safety cover for a transmission chain or belt.

[0014]

Since the present invention is constructed as described above, it is possible not only to eliminate the time loss at the time of switching the granular material and to simplify the equipment, but also to remove the residual granular material by separating and replacing the feeder portion. This makes it possible to easily collect and replace the feeder, and to easily clean and wash the feeder unit without using a dedicated device.
