It is provided.
Therefore, the raw material attached to the surface of the diffusion plate 2 comes into contact with the scraper 10 and is shaken off. Further, the respective lower ends of the scrapers 10 and 10 are connected and reinforced by a connecting plate M. Furthermore, in the diffusion part,
In order to prevent the raw material put on the sieve N from the diffuser from jumping out of the sieve N, a hanging-up enclosure part P is provided so as to surround the periphery except the front side.

The diffusion charging device K is provided with a frame 11 so as to surround both the diffusion section and the conveyor section, and the side on which the diffusion section is arranged and the conveyor section are provided via the frame 11. The side on which is arranged is integrally connected, and both are integrated. Specifically, the frame 11 extends along each of both sides of the conveyor 1, passes through the vicinity of the rotating shaft 9 on the diffusion unit side, and extends in parallel to the front and further in parallel with the first frames 11a, 11a.
And second frames 11b and 11b extending parallel to each other so as to be orthogonally connected to the front and rear ends of the first frames 11a and 11a. Furthermore, at the front end of the first frame 11a, 11a, it stands up a short distance and is bent at a right angle.
A third frame 11c that stands up in a gate shape and extends in a parallel position that is different from that of 11b is installed. In this way, the diffusing portion is supported by the frame 11 by receiving the rotating shafts 9, 9 by the first bearing portions 12, 12 provided at both ends of the third frame 11c. In addition, the conveyor section includes the first frames 11a and 1
Second bearing portions 13, 13 provided on the front side of 1a
In addition, the central axis of the pulley 3 that is closer to the diffusing portion is received, and the third bearing portion 14 provided on the rear side of the first frames 11a and 11a is farther from the diffusing portion. The central axis of the pulley 3 is received so that it is supported by the frame 11. The second bearing portion 13 is provided with a driving device G for rotating the pulley 3, and the third bearing portion 14 is provided with a tension adjusting tool 15 for adjusting the tension of the belt 1a. ing.
The tension adjuster 15 moves the pulley 3 back and forth in the longitudinal direction of the belt 1a while supporting the central axis of the pulley 3 and fixes the belt 1a at a position where the belt 1a has a required degree of tension.

The partition 5 is supported by the frame 11 by a plurality of elongated plate-shaped supporting members 16 and 16 which are bent at right angles on the way, and these supporting members 16 and 16 are
One end is fixed to the outer wall surfaces of the first partitions 5a and 5a, and the other end is fixed to the middle portion of the first frames 11a and 11a. Further, a plate-like body 17 having a plurality of recesses at its upper end is located inside the support member 16 and attached to the first frames 11a, 11a. The central axes of the rollers 4 and 4 are removably received in the plurality of recesses, respectively, so that the plurality of rollers 4 and 4 are supported by the frame 11 via the plate-shaped body 17. .

Further, the diffusion charging device K itself is mounted on the first frame 11a and supported by four prismatic supporting portions 25 extending downward, and is installed at a required installation place.

The conveyor part is located below the front end of the conveyor 1 facing the diffuser 2 and receives the raw material falling from the conveyor 1 once and then directly drops it onto the upper surface of the diffuser 2. A receiving portion 18 is provided. The contact receiving portion 18 has a swash plate portion whose inclination angle is arbitrarily adjusted, and the swash plate portion is staggered with respect to each of the second and third frames 11b, 11b, 11c, 11c. It is provided wide so as to extend in parallel and cover the lower side of the pulley 3 which is closer to the diffusion portion. When it is difficult to bring the conveyor unit and the diffusion plate 2 of the diffusion unit close to a required distance due to various reasons, the contact receiving unit 18 connects the one end side of the conveyor unit and the diffusion plate 2 of the diffusion unit. It functions as an adjusting mechanism that allows the distance between them to be adjusted. That is, according to the contact receiving portion 18, the distance between the one end side of the conveyor portion and the diffusion board 2 is changed by changing the mounting position on the frame 11 or adjusting the angle of the swash plate portion. Can be easily adjusted.

Further, in the diffusion feeding device K, the belt 1a is placed at a position closer to the pulley 3 on the side closer to the diffusion portion, specifically, at a position where the belt 1a is wound and the traveling direction is reversed.
The raw material stripping 19 is provided along the vicinity of the surface of the. Thereby, after the raw materials are dropped, the belt 1
Even if the raw material is left on the surface of a, for example, the raw material peeling unit 19 can peel off the attached raw material.

In the diffusion charging device K having the above structure, the pulley 3 is rotated by the driving of the driving device G, and the operation of the conveyor 1 is started in accordance with the rotation,
To start. Then, as shown in FIG. 2, the raw material is fed from the raw material carry-in port 20 already installed at the site, for example, by sliding under its own weight. Then, this raw material enters the carry-in range defined by the partition 5, is placed on the surface of the conveyor 1, and continuously and automatically to one end side of the conveyor section, that is, to the front end side of the conveyor 1. Then, the sheet is leveled and conveyed by contacting the leveling member on the way. When reaching the front end side of the conveyor 1, the raw material is dropped from that position onto the upper surface of the diffusion plate 2 of the diffusion section.
At this time, the pad receiving part 18 may be interposed between the conveyor 1 and the diffusion plate 2, and the raw material may be once applied to the pad receiving part 18 and dropped on the upper surface of the diffusion plate 2. On the other hand, the diffuser 2 has arrows R and R around the rotation axis 9.
Since it rotates in one direction, the raw material dropped on the upper surface of the diffusion plate 2 is diffused and input onto the sieve N located below the diffusion plate 2.

In this way, in this diffusion charging device K, the side on which the conveyor section is arranged and the diffusion section are arranged so that the raw material is not concentratedly dropped on one side of the two diffusion plates 2, 2. Since the side and the side are integrally connected and integrated, one end side of the conveyor unit can be preliminarily positioned so as to face the diffusion plate of the diffusion unit at an appropriate angle. Therefore, it is said that the raw materials are diffused and put on the sieve N,
It is possible to surely achieve the intended purpose. That is,
The two diffusion boards 2 and 2 are provided so as to be lined up along one end side of the conveyor unit with a predetermined space from the conveyor unit. And, regardless of the direction in which the raw material is sent from the site, the partition 5 defines the range in which the raw material should be carried in, so it is reliably carried into the carry-in range and the conveyor automatically moves. It is placed on No. 1 and conveyed to one end. In this way, the raw material can be reliably dropped from the proper position onto the upper surface of the diffusion plate 2.

The one end side of the conveyor means the position at which the raw material is dropped onto the diffusion plate 2, and is, for example, the front end side of the conveyor 1 or the portion receiving the raw material. To do.

Further, the diffusion charging device K is not limited to the above-mentioned embodiment, and various modifications can be made. For example, the carry-in range is preferably surrounded by partitions 5 on all sides, but the rear partition 22 may be omitted. Further, if the function as the leveling member 7 is not required, the front partition 21 may be omitted. Therefore, the presence of the first partitions 5a, 5a which are erected along at least both sides of the conveyor 1 is sufficient for exerting the effects. In addition, the partition 5 may be changed in the width of the carry-in range or the like depending on the use situation or purpose of use,
As in the illustrated embodiment, the first and second partitions 5
It is not necessary for a and 5b to be provided in the longitudinal direction of the conveyor 1 or along both sides of the conveyor 1.
Therefore, the partition 5 may be configured by a so-called hopper or the like. Furthermore, the partition 5 may not be provided if it is clearly recognizable that the raw material is carried onto the surface of the conveyor 1, or depending on other circumstances.

Further, it is desirable that the conveyor 1 can switch its traveling direction. This way
For example, a raw material that has a strong adhesive property and may be clogged when put on the sieve N can be prevented from being put on the sieve N by switching the traveling direction of the conveyor 1. And such a raw material is on the conveyor 1
It is convenient to collect it when it falls from the rear end side and use it as, for example, a roadbed material that constitutes a road body structure of a road, because it is not necessary to dispose of it. When the traveling direction of the conveyor 1 is changed, the rear partition 22 is removed or the skirt portion 6 provided on the rear partition 22 is removed to form a gap with the surface of the conveyor 1. It is good to do so.

Further, the conveyor 1 does not have to be linearly formed in the longitudinal direction thereof, and may be curved in a curved shape depending on the installation situation at the site. Further, the conveyor 1 is not limited to a belt conveyor, and may be, for example, a screw conveyor, a bucket conveyor, or any other well-known conveyor as long as raw materials can be loaded and reliably conveyed to one end of the conveyor section. Good.

Further, in the case of the illustrated embodiment, the diffusion unit is
Since it is assumed that the highly adherent raw material is diffused and introduced, as described above, the diffusion plate 2 has a special shape, and the scraper 10 is included in the known diffusion type. It is different from the diffusion unit in the charging device. However, depending on the usage situation and purpose, the diffusion plate 2 may be, for example, a circular disc, or the scraper 10 may be omitted, as in the known diffusion unit.

Further, as described above, the contact receiving portion 18 acts as an adjusting mechanism for adjusting the distance between the one end side of the conveyor portion and the diffusion plate 2 of the diffusion portion. As another adjusting mechanism, the conveyor unit may be configured to be slidable in a direction toward or away from the diffuser 2. That is, in this case, the conveyor 1 has the second bearing portion 13 and the third bearing portion 14 on the first frames 11a and 11a along both sides of the conveyor 1 so as to be movable in the longitudinal direction thereof. Is configured to be slidably mounted. This allows the conveyor unit to approach or separate from the diffusion plate 2, and for example, the distance between the conveyor unit and the diffusion plate 2 can be adjusted to an appropriate distance depending on the type of raw material.
