[Industrial use]

According to the present invention, a process rotating body including a treatment value and a discharge wing is provided at the end of screw conveyor 2, and the discharge hole of the processing case incorporating the process rotating body is connected to the beginning of the second longitudinal conveying conveyor. It is related with the 2nd reduction part of the threshing apparatus made to pass.

[Prior art]

The second reduction part of this type of threshing apparatus is threshed again by means of a rotating body of the conglomerate (second object: second object) transported in the treatment case by the second screw conveyor, and the processed object is subjected to the second longitudinal direction. It has been proposed to feed the starting end of the conveying conveyor and to feed it upwards with this second longitudinal conveying conveyor to reduce the sorting part.

The process rotating body provided in the second reduction part is provided with a plurality of discharge blades conventionally formed in a plate body in the longitudinal direction at equal intervals in the circumferential direction at the end end of the screw conveyor 2, and each of the plurality of discharge blades Is treated by fixing at equal intervals in the axial direction of the No. 2 screw conveyor.

The screw conveyor No. 2 in the threshing apparatus was constituted by a single screw blade, as shown previously in Japanese Patent Application No. 63-99538 filed by the present applicant.

In addition, the periphery wall portion provided with the accommodation value is configured as a cover which is free to detach and removes the periphery wall portion, thereby opening the entrance for maintenance inspection of the inside of the processing case and the processing rotating body while It was comprised so that it was easy to remove and perform maintenance inspection.

[Problem to Solve]

In the process rotating body configured as described above, even if there is a chaebol powder at any position along the axial direction of the second screw conveyor, the treated value and the discharge wing have almost the same effect on the chaebol powder.

For this reason, the conglomerate sent by the second screw conveyor into the treatment case is threshed further when it reaches the innermost end of the treatment case and the staying time becomes longer. As a result, many conglomerates, which are not sufficiently threshed and discharged in the initial stages transferred into the treatment case, or conglomerates that are likely to stagnate in the treatment case, are not even in reprocessing.

In addition, in the threshing apparatus described in the beginning, the role of the second screw conveyor is to collect and collect the conglomerate of rice with a branch or straw crumb mixed with rice in one side direction, and connect this end to the second end. The conglomerate is handed over to a processing rotor having a rotary blade which rotates integrally with a screw conveyor.

Therefore, the screw conveyor No. 2 of the threshing apparatus according to the above-described technique is used to transverse the conglomerate by only one screw blade, but the pitch of the screw blade is mainly determined by obtaining an efficient transverse speed. Since the tendency is strong, at the end of the second screw conveyor which carries out the rotary blades, the transportation state of the chaebol may also change abruptly here, so that the chaebol, which is transversely transported to the relatively old stone, is blocked or not sufficiently dispersed. The phenomenon that performance and efficiency as a 2nd processing mechanism deteriorate because it is conveyed to a rotary blade as a lump shape has been recognized often. This was especially noticeable in the case of wet threshing.

In this regard, the method of narrowing the screw pitch of the second screw conveyor to reduce the feed rate of the chaebol to the rotary blade to smoothly carry out the transfer, but this time, the transverse transportation of the chaebol is carried out. A new problem arises that the speed is slowed and the collection efficiency itself is deteriorated.

In addition, since the entrance to the maintenance inspection is blocked by the mounting of the circumferential wall part, the receiving value attached to the circumferential wall part, the treated value installed in the processing rotating body, You cannot adjust the attachment position of the circumferential wall part by visually seeing the distance between them.

As a result, there is a drawback that the gap between the accommodated value and the treated value in the state of mounting the peripheral wall portion cannot be optimized, and disadvantages such as insufficient processing and damage of the grain of grain and clogging of the grain of grain into the gap are likely to occur.

In view of such a situation, the present invention equalizes the threshing in the processing case, and efficiently discharges the threshing ash from the threshing ash, and reduces the transverse speed by studying the second screw conveyor. It aims to solve the above-mentioned shortcomings by making it possible to smoothly receive the chaebol powder to the processing rotating body without any problems, and to perform the maintenance check of the peripheral wall portion with the accommodation value advantageously. .

[Means for solving the problem]

The feature of the present invention lies in that the distance from the center of the discharge blade to the circumferential edge is made longer as the end of the screw conveyor.

Moreover, as a suitable embodiment, the following various structures can be taken. Only at the end of the transportation end of No. 2 screw conveyor, arranging the screw blades in plural lines and arranging them in order to form a circumferential wall portion free of attachment and detachment. An attachment portion to be freely attached to the processing case in the axial center direction, means for positioning the circumferential wall body at a predetermined position in the axial center direction with respect to the attachment portion, and detaching the circumferential wall body from the attachment portion. To devise attachment means for free installation, and its action and effect are as follows.

[Action]

In other words, if the distance of the peripheral edge of the blade is longer from the axis of the blade, the rotational path of the blade is larger and the discharge capacity is higher. Therefore, the discharge power is higher at the end of the second screw conveyor.

Therefore, in the early stages that have been transferred into the treatment case, the discharge capacity is relatively low, so that the chaebol fraction released from the treatment case is reduced without being sufficiently recurved. In addition, if the conglomerate in the treatment case is transported to the inner end and continues to be threshed again, the discharge capacity increases accordingly, so that the conglomerate that is likely to stagnate decreases.

In addition, while the conglomerate powder is transported under the screw pitch action as conventionally, it is divided into multiple paths, that is, dispersed by a plurality of screw blades formed at the end of the second screw conveyor, and at the same time, the borehole into the processing rotating body. There are also a plurality.

Moreover, as an attachment form of a circumferential wall part, the operation form of attaching an attachment part to a process case first and attaching a circumference wall part main body to the attachment part can be employ | adopted. In the attachment of the attachment portion to the treatment case, the positional relationship of the axial center direction of the attachment portion with respect to the treatment rotation body in the treatment case can be easily seen. Therefore, the attachment portion is processed so as to be located in any axial direction with respect to the treatment rotation body. Can be attached to the case.

On the other hand, in attachment to the attachment part of the circumferential wall part main body, the axial center position of the circumferential wall part main body with respect to an attachment part is determined uniformly by a restriction means. Therefore, the attachment part is attached to the treatment case by adjusting the attachment portion at the axial center position which makes the axial center position of the receiving blade of the peripheral wall portion main body appropriately, and attaching the peripheral wall portion main body to the attachment portion to the processing rotary body of the receiving blade. It is possible to optimize the axial position with respect to.

[Effect of design]

According to the present invention, it is possible to perform proper rethrowing of the chaebol powder conveyed in the processing case, and to efficiently discharge the crushed ash powder from the second longitudinal conveying conveyor.

In addition, the end of the second screw conveyor, which has a plurality of screw blades, has the same effect as the screw pitch is reduced. As a result, the end of the screw conveyor pushes out the object by lateral transport to obtain a highly efficient lateral transport speed. Since the chaebol powder is sufficiently released and smoothly received by the processing rotating body, it is also possible to achieve higher efficiency than the conventional art in the case of operating normally, as the conventional problems can be eliminated.

The only means for this is to overlap a plurality of screw blades only at the end of screw conveyor 2, which makes it lighter and cheaper than when screw blades are overlapped in the entire screw conveyor. It does not involve the design change of other parts concerned and there is no economic disadvantage, and there is an advantage that can satisfy the desired purpose.

In addition, the circumferential wall portion with the retained value can be attached and detached freely, and the maintenance and repair can be advantageously performed, but the desired chaebol can be treated reliably.
