Description

[Detailed explanation of the invention] [Industrial application field] This invention temporarily stores loose materials such as garbage,
The present invention also relates to a storage and discharge drum having a discharge function.

[Conventional technology]

An example of a conventional storage and discharge drum is shown in FIG. The drum body consists of a cylindrical part 2 with a spiral blade 1 inside and a tapered part 3, and is supported by a guide roller (not shown) by a rail 4 provided around the periphery and rotates around a central axis 5. It is maintained that Reference numeral 6 is a chute for throwing in garbage and the like.

Reference numeral 7 denotes a discharge port, which is opened and closed by an opening/closing lid 9 that is swingably supported by a support shaft 8. Reference numeral 10 denotes a cover plate, which is rotatably attached to the arm 12 via a bearing body 11, and when closed, comes into contact with the discharge port 7 and rotates together with the drum.

[Problem that the invention attempts to solve]

However, in such a conventional device, if a long and thin object such as a string 13 is caught between the opening and closing lid 9 and the discharge port 7, the part that hangs down beyond the periphery of the lid plate 10 will be damaged by the lid. As the plate 10 rotates, it wraps around the arm 12 and the center of the drum body,
There are drawbacks such as interfering with the smooth rotation of the drum, causing damage to various parts, and the inability to easily remove entangled long objects.

The present invention eliminates the above-mentioned drawbacks of the conventional one, and even if a string is caught between the lid plate and the discharge port, it will not get tangled in the fixed part, and will only be able to wrap around the end of the drum body on the discharge port side. The object of the present invention is to provide a storage and discharge drum that can be easily removed.

[Means for solving problems]

The present invention includes a drum body equipped with a spiral blade inside, and a lid plate that opens and closes the discharge port of the drum body and is supported so as to be in contact with the discharge port and rotate together with the drum body when the drum body is closed. In a storage/discharge drum comprising an opening/closing lid having a conical annular guide around the periphery, the lid plate is made of a disk larger than the outlet diameter of the discharge port, and the drum body has an outer circumferential wall on the discharge port side. , a guide having a conical surface inclined opposite to the conical surface of the annular guide is provided, and an end of the drum body closer to the discharge port than a portion where the guide is provided is formed into a cylindrical portion. This is a unique storage and discharge drum.

[Effect]

In the storage and discharge drum of this invention, the guide allows
It is possible to prevent a string or the like that is pinched and hanging to the outside from wrapping around the center portion of the drum body.

On the other hand, in addition to the annular guide, the opening/closing lid has a lid plate that is formed larger than the outlet diameter of the outlet, and the part that protrudes from the outlet becomes a vertical wall, which prevents strings, etc. from going over the opening/closing lid. be able to.

Therefore, it is possible to effectively prevent strings from becoming entangled with the fixed portion.

In the present invention, the end of the drum body closer to the discharge port than the guide is formed into a cylindrical portion, so that an annular space with the cylindrical portion as the bottom is formed between the guide and the opening/closing lid. Therefore, a hanging string or the like wraps around the cylindrical part in this annular space. The string wrapped around the cylindrical portion can be easily removed from the drum body by opening the opening/closing lid and moving it in the axial direction of the drum body while still being wrapped.

In addition, since the bottom area of the annular space is large due to the cylindrical part, even if a fairly long string is wound around many times, the winding height is low (the winding width in the direction of the drum axis does not increase), and the string can be used to open and close the lid. It is possible to further prevent the drum from wrapping around the center of the drum body.

〔Example〕

An embodiment of the present invention will be explained using diagrams.

The storage and discharge drum 14 of the present invention is different from the storage and discharge drum shown in FIG. 1 in the vicinity of the discharge port 7 and the opening/closing lid 23, so only these parts are shown in FIG.

The lid plate 10 of the opening/closing lid 23 is a disc having a diameter larger than the exit diameter of the discharge port 7, and is provided with a conical annular guide 20 around the disc.

The end of the drum body on the discharge port 7 side is formed into a cylindrical shape, and a guide 21 having a conical surface with an inclination opposite to that of the annular guide 20 is attached to the cylindrical portion at the end of the drum body on the discharge port 7 side. The cylindrical portion 22 is left in place.

FIG. 2 shows a storage and discharge system, in which 14 is a storage and discharge drum, 15 is a cylinder for opening and closing the opening/closing lid 23, 16 is a conveyor, 17 is an incinerator, 18 is a feeder, and 19 is a hopper inside the feeder 18. In order to adjust the amount of garbage discharged from the storage and discharge drum 14 so that the garbage level remains within a predetermined range, the rotation of the storage and discharge drum 14 is started and stopped, and the lid 23 is opened and closed.
This is a level controller that operates the cylinder 15 for opening and closing.

When only the discharge work is performed, the operations are performed in the order shown in the flowchart of FIG. 3. That is, when the level controller 19 detects that the garbage level has reached the lower limit, the storage and discharge drum 14 is activated by the signal, and the cylinder 15 is then operated to open the opening/closing lid 23 and the garbage is discharged. It is supplied to a feeder 18 via a conveyor 16. When it is detected that the dust level has reached the upper limit, a signal from the level controller 19 causes the storage and discharge drum 14 to stop rotating, and then the opening/closing lid 23 is closed.

In this way, by closing the opening/closing lid 23 after the rotation of the drum has stopped, it is possible to prevent entangled strings, etc., and also to prevent the trouble of strings becoming tangled in a complicated manner inside the drum and growing into large ropes. It can also be prevented.

However, when continuous operation is performed by simultaneously receiving, storing, and discharging garbage, the lid 23 may be rotated with the lid 23 closed. Between 23 and
Even if a string or the like is caught in a long hanging state outside, it will be difficult to cross over the opening/closing lid 23 due to the vertical wall of the peripheral edge of the lid plate 10, and even if it tries to wrap around the center of the drum body or going over the opening/closing lid 23. Guide 21
Then, it is returned to the discharge port 7 side by the conical surface of the annular guide 20 and wrapped around the cylindrical portion 22 .

[Effect of idea]

With this invention, even if a string gets caught when closing the opening/closing lid, the action of the guide, opening/closing lid, and cylindrical part prevents the string from getting wrapped around the opening/closing lid or to the center of the drum body. Prevents accidents caused by entanglement with parts, allowing safe and smooth driving. In addition, the pinched string or the like is wrapped around the cylindrical portion at the end of the drum body on the discharge port side, so it can be easily removed.
