[Prior Art] Conventionally, this kind of apparatus has been provided with a shutter slidably provided at the raw material supply port.

[Problems to be solved by the invention] The conventional techniques described above had the following problems.

However, even though this shutter is slidable, it cannot be removed from the raw material supply port.

This shutter is used not only to adjust the flow rate but also when there is an abnormality in the hopper or raw material supply port.

It is unknown when such an abnormality will occur, and it may never occur.

Even in this situation, if the shutter is left attached, feed will stick to this part, causing rust and staining, which can cause malfunctions.

The present application has been made in view of the problems of the prior art, and its purpose is to provide a solution to the above-mentioned problems.

[Means for Solving the Problems] In order to achieve the above object, the present invention is as follows.

In the feed drawing device body, the feed outlet 7 is formed in the distal end surface of the horizontal pipe, and the side wall of the connecting pipe includes:
A horizontally long opening 8 having a dimension slightly longer than the radius of the connecting pipe is formed, a removable lid 9 is attached to the opening, and a round bar is placed inside the connecting pipe in the shape of a cross on a plane. Assembled receiving frame 10
The damper body 11, which is stretched horizontally and inserted into the opening as necessary, is configured in an inverted U shape facing left in the plane, and has a radius slightly shorter than the radius of the connecting pipe. A semicircular left plate body 11A, and a semicircular left plate body 11B, which is configured in an inverted U shape facing right in the plane and whose radius is slightly shorter than the radius of the connecting pipe. , an emergency damper in a feed pulling device, in which the tips of the inner straight edges are connected by a vertical pin 11C, and handles 11A' and 11B' are respectively attached to the rear end of each inner straight edge. It is.

[Effect] Explain along with the effects.

[Embodiments of the invention] The present invention is intended to fully solve such problems, and the details of the embodiments of the invention will be described below with reference to the drawings.

1 is an emergency damper in the feed pulling device of the present invention.

The configuration is such that a bellows part 4 is connected to the lower part of the feed storage hopper 2 via a connecting pipe 3,
A horizontal pipe 5 with a direction orthogonal to the lower end of the bellows part.
In the feed drawing device body, the feeding screw 6 is rotatably installed inside the horizontal pipe, and a feed discharge port 7 is formed on the distal end surface of the horizontal pipe. A horizontally long opening 8 having a dimension slightly longer than the radius of the connecting pipe is formed in the side wall.

Further, a removable lid 9 is attached to the opening, and a receiving frame 10 made of round rods arranged in a planar cross shape is horizontally stretched inside the connecting pipe.
The damper body 11 is inserted into the opening as necessary.

Therefore, the damper body 11 is a semicircular left plate body 1 that is configured in an inverted U shape facing left in the plane and whose radius is slightly shorter than the radius of the connecting pipe.
1A and the semicircular right plate 11B, which is configured in an inverted U shape facing right in the plane and whose radius is slightly shorter than the radius of the connecting pipe, are connected to each other at the tips of their inner straight edges. The parts are connected by vertical pins 11C, and left and right handles 11A' and 11B' are respectively attached to the rear end parts of each inner straight edge.

When connecting with the vertical pin 11C, specifically, referring to FIG. 5, the inner straight edge portion of the left plate 11A and the inner straight edge portion of the right plate 11B are overlapped. , and its tip portions will be connected.

As a result, the right and left handles 11B' and 11A' are in a vertically overlapping state.

9A is a small projection, and 9B is a bolt.

[Effects of the invention] Next, how to use the invention will be explained along with its effects.

Normally, when the transporting screw 6 is rotated with the lid 9 attached, the feed in the hopper 2 is discharged from the feed outlet 7.

However, if an abnormality occurs in which foreign matter gets mixed into the feed and gets caught in the conveying screw 6, causing the operation to stop, the bolts 9B are loosened, the lid 9 is removed, and the plate 11A of the damper body is removed as shown in FIG. ,11
When B is pulled inward around the vertical pin 11C to reduce its size and inserted through the opening 8, and the left and right handles are opened outward, the damper body is stretched inside the connecting pipe 3. (See Figure 6).

As a result, since the feed in the hopper is stopped from flowing down, maintenance work on the conveyance screw, etc. can be performed.

In addition, regarding the contamination of foreign substances as mentioned above, work gloves, hats, etc. are often dropped when transferring the transported feed into the hopper, which can cause accidents such as screws getting caught in the screws and being damaged. .

In this case, conventionally, the feed in the hopper had to be transferred to another location and then the screw had to be repaired, which was inconvenient.

However, in the present invention, the damper body can be installed in the above-described manner to prevent the feed from flowing down and perform the necessary work, so it is convenient because the large-scale and time-consuming work can be omitted.

Furthermore, in the present invention, the damper body is configured to be able to be inserted into and removed from the connecting pipe, so in conventional shutters that cannot be removed from the raw material supply port, inconveniences such as feed sticking may easily occur, but the present invention Since the device is configured to be freely inserted and removed, the above-mentioned inconvenience is unlikely to occur.

In the present invention, even if feed adheres to the damper body after removal, the adhering feed can be easily removed at hand.

When the damper body is used, the lower surface of the damper body is supported by the receiving frame, so that it can reliably withstand the heavy pressure of the feed that is about to flow down.

In addition, when attaching or removing the device, the necessary operations can be carried out reliably by supporting the left and right handles and opening them outward or closing them inward, which is an extremely simple operation.
