Install 8. FIG. 3 shows the upward endless chain 13 in which the elastic scraping bodies 18 are turned upside down. The elastic scraping body 18 connects the scraping portion 19 corresponding to the lateral protruding portion 17 with a thin connecting portion 20,
The scraping portion 19 is formed with three through holes 21 in the left-right direction. Of the three through-holes 21 of the scraping part 19, two on the left and right sides
One is a rotation stopper fitting protrusion 2 formed on the side protruding portion 17.
2, the rotation stopper fitting protrusion 22 of the side protrusion 17
A mounting hole 23 having a screw groove is formed in the middle of the above, the through hole 25 of the plate-shaped mounting member 24 is aligned with the mounting hole 23, and the fastener 26 such as a screw is screwed and mounted.

The mounting member 24 is formed at the bending engaging portion 27 by bending the upper end thereof toward the side projecting portion 17 based on the operating state of the elastic scraping body 18, and the bending engaging portion 27 is attached to the mounting member 24.
When the through hole 25 of the side projection 17 is aligned and brought into contact with the mounting hole 23, the through hole 25 is engaged with the upper edge of the side projection 17, and the mounting member 24 rotates when the mounting member 24 is mounted. It acts as a detent to prevent In this case, in the lateral protruding portion 17, when the step-shaped anti-rotation abutment surface 28 is formed on the upper portion of the elastic scraping body 18 at a predetermined interval, the bending engagement portion 27 which is about to rotate is anti-rotational. It is suitable because it hits the abutting surface 28 and acts as a detent. The elastic scraping body 18 is moved such that the scraping portion 19 and the connecting portion 20 are located below the side projection 17 in a side view and slidably contact the upper surface of the bottom plate 30 of the machine casing 1.

Also in the point, the elastic scraping body 1 described above is used.
The configuration for facilitating attachment / detachment / replacement of 8 is a rational configuration.

[0011]

[Operation] Next, the operation will be described. When the motor is energized,
The drive sprocket 10 rotates and the drive sprocket 10
Rotates the endless chain 13 to move the carrier 12 from the starting end to the ending end of the machine casing 1. Then, endless chain 1
On both left and right sides of the predetermined one of the three side links 15,
A lateral protrusion 17 that protrudes in a direction intersecting the traveling direction of the chain 13 is provided, and the lateral protrusion 17 allows the carrier 12 to move.
Therefore, the lateral protrusion 17 that becomes the carrier 12 is formed.
Moves from the front side of the supply unit 2 to the front side of the terminal outlet 5 and conveys a conveyed product such as grain.

An elastic scraping member 18 made of an elastic material such as urethane rubber is provided on each side protrusion 17 of a specific carrier 12 with a predetermined number of the carriers 12 being placed.
Since the elastic scraping body 18 is configured to slide on the bottom plate 30 of the machine casing 1, the elastic scraping body 18 is attached.
Conveys the residue on the bottom plate 30 which the conveyer 12 cannot convey. Since the elastic scraping body 18 constantly slides on the bottom plate 30 and is worn, it needs to be replaced every predetermined period.

The elastic scraping body 18 is a lateral projecting portion 17 projecting from the both side links 15 of the endless chain 13 to the left and right sides, respectively.
The scraping portion 19 corresponding to the above is integrally connected by a thin connecting portion 20, and the scraping portion 19 has three through holes 2 in the left-right direction.
1, while each side protrusion 17 has a scraping portion 19
Since the anti-rotation fitting protrusions 22 projecting in parallel with the transport direction are provided in the portions corresponding to the two on the left and right sides of the three through holes 21 of, the scraping portion 19 has three through holes 21. The two pieces on both the left and right sides are fitted into the detent fitting projections 22 formed on the side protrusions 17 to bring them into a temporarily fixed state, and the elastic scraping body 18 is brought into contact with the mounting member 24 so that one piece is attached. Ingredient 2
Install by 6. Therefore, since the elastic scraping body 18 can be attached and detached by the single fastener 26, the elastic scraping body 1 can be detached.
The replacement work of No. 8 can be done very easily, and the work time can be remarkably shortened.

That is, the scraping portion 19 of the elastic scraping body 18
Is fixed to the side protruding portion 17 at three positions by the anti-rotation fitting projections 22 and the fasteners 26, and the attachment work is performed only at one place. Therefore, the elastic scraping body 18 must be replaced. It is easy and the working time can be shortened. Further, since the scraping portion 19 of the elastic scraping body 18 may be attached to the side projecting portion 17 without being displaced, if only the center of the scraping portion 19 is fixed by the fastener 26, of course at the time of attachment. Therefore, even if a load is applied in the rotational direction during the transportation of the grain, it is supported by the rotation preventing fitting projection 22.

Further, the elastic scraping body 18 is provided with the side protruding portion 17
The mounting member 24 fixed to the above is formed into the bending engaging portion 27 by bending the upper end toward the side projecting portion 17 side based on the operating state of the elastic scraping body 18, and the bending engaging portion 27 is attached to the mounting member 24. When the through hole 25 of the side projection 17 is brought into contact with the mounting hole 23 of the side projection 17, the upper edge of the side projection 17 is engaged. The force in the rotation direction of the fastening tool 26 acts on the bending engagement portion 27.
However, since this is prevented, also in this respect, the mounting becomes easy and the working time can be shortened.

In this case, since the side protrusion 17 is formed with a step-shaped anti-rotation abutment surface 28 at a predetermined distance from the upper portion of the elastic scraping member 18, the bending to rotate is made. The side of the engaging portion 27 opposite to the portion which abuts against the upper edge of the lateral protruding portion 17 abuts against the rotation stop abutting surface 28 to prevent rotation, which facilitates attachment and shortens the working time. In the elastic scraping body 18, the lower edge of the scraping portion 19 and the connecting portion 20 is located below the lower edge of the lateral projecting portion 17 in side view. Case 1
The bottom plate 30 is securely slidably contacted with the upper surface of the bottom plate 30 to move the residue.

In this case, since both side edges of the scraping portion 19 are formed so as to protrude to the left and right sides from the side projecting portions 17, the scraping portion 19 is moved close to or in sliding contact with the left and right side plates 31 of the machine casing 1. This is preferable because it makes it possible to further convey the residue on the bottom plate 30. In the endless chain 13 and the carrier 12, if the both-side links 15 and the side protrusions 17 are made of hard synthetic resin, noise during movement is reduced. In this case, as already described, by providing the elastic scraping bodies 18 on some of the transport bodies 12 but not on all of the transport bodies 12 at predetermined intervals, the elastic scraping bodies 18 simply transport the residue. In addition to the above, the function of supporting the movement of the endless chain 13 and the carrier 12 can also be expected, and the contact time with the bottom plate 30 can be reduced, noise can be reduced, and abrasion resistance can be improved, which is preferable. Also in the above, the configuration for facilitating the attachment / detachment exchange of the elastic scraping body 18 is a rational configuration.

Further, since the elastic scraping body 18 can be easily replaced as described above, only the elastic scraping body 18 that has been worn by contact with the bottom plate 30 needs to be replaced, and all the carrier bodies 12 can be replaced.
There is no need to replace the endless chain 13 with. Therefore, the lateral protruding portion 17 of the carrier 12 can be integrally molded with the both side links 15 of the endless chain 13 by the resin, and also in this respect, the cost is reduced and the rational configuration is achieved.
