Description

[Detailed Description of the Invention] [Industrial field of application] In the present invention, a handling room top plate having a handling barrel attached and forming an upper part of the handling room is provided on the side opposite to the handling port in which the feed chain is disposed. The present invention relates to a thresher mounted so as to be vertically swingable around an axis that is positioned and is substantially parallel to the axis of the handling cylinder.

[Conventional technology]

The threshing machine described above, for example, as disclosed in Japanese Patent Laid-Open No. 58-220618, can open the handling room by simply swinging up and swinging the handling room top plate to which the handling cylinder is attached, and handling from the handling room. The body can be taken out so that cleaning and other work in the handling room can be done easily and quickly.

In this type of threshing machine, conventionally, the receiving net is attached in a state of being removed all at once and by bolting, which has the following disadvantages.

[Problems to be solved by the device]

That is, when attaching and detaching the receiving net for cleaning, inspection, replacement, etc., it is necessary to attach and fix the receiving net and release the receiving net with a troublesome labor of rotating the mounting bolt to loosen or tighten it. Furthermore, the receiving net must be handled with a size that includes the entire required area and taken in and out of the handling room and aligned with the predetermined assembly position, which improves the efficiency of work in the handling room. In terms of aspects, it has not yet been fully achieved.

An object of the present invention is to modify the receiving net so that it can be easily removed and assembled easily.

[Means for Solving the Problems]

The feature of the present invention is that the handling chamber top plate, to which the handling barrel is attached and which forms the upper portion of the handling chamber, is located on the side opposite to the handling port in which the feed chain is disposed and is substantially parallel to the handling barrel axis. In a thresher that is mounted so that it can swing up and down around its axis, the receiving net consists of a plurality of split netting parts that can be split in the circumferential direction of the handling cylinder. The end of the net portion on the feed chain side is locked by a locking body that can be inserted into and removed from the contact regulation member on the side of the handling chamber in the circumferential direction of the handling cylinder, and the other end side is the handling barrel. The engaging portion is locked via an engaging member having a locking portion for a fixed pin fixed to the handling chamber side along the axial direction, and the engagement portion is provided around the handling body with respect to the fixed pin. It can be inserted / removed from the direction, the inlet side is as narrow as the outer diameter of the fixing pin, and the inner side is Is formed in a wider and wider shape than that of the feed chain, and further, the divided net portion distant from the feed chain has its feed chain side end abutted against the end of the divided net portion, and It is configured to be locked to its end through a locking member that restricts the movement toward the inside of the handling room, and the other end side is configured to be fixedly held in a pressed state by the handling room top plate. Yes, its action and effect are as follows.

[Action]

The receiving net can be divided into smaller divided net portions than the case where the receiving net is formed as an integral member over the entire installation range, and handling for moving operation and positioning operation can be performed more easily than the conventional one.

Moreover, since the split netting part can be removed to the inside of the handling room and mounted from the inside of the handling room, the handling room top plate with the handling barrel mounted can be raised and swung to receive the wider handling room. By using it as a passage for attaching / detaching the net, it is possible to easily move the receiving net when attaching / detaching.

Further, the receiving net can be attached and fixed or released by simply moving the divided net portion so as to engage with and disengage from the attachment portion on the thresher side.

In other words, when locking the divided net portion on the feed chain side of the divided net portions to the thresher, first, the end portion on the back side, that is, the end portion on the side far from the feed chain, After engaging with a pin along the handling barrel axis direction on the thresher side via an engaging member with a locking engagement part, move the split net part to the handling port side, and the end on the feed chain side. The portion can be locked to the contact regulation member on the handling chamber side through a pin and a pin hole whose axial center is oriented in the circumferential direction of the handling cylinder,
Further, in the inserted state, the divided netting portion can be held without holding it by hand.

Further, also in the split netting portion distant from the feed chain, the end portion on the feed chain side is brought into contact with and locked to the end portion of the split netting portion, and the other end side is
Since the position is regulated by the top plate of the handling room, it can be easily attached and detached.

[Effect of device]

As a result of the above configuration, the receiving net can be easily handled, and the receiving net can be fixed or unlocked simply by moving the divided net parts. In addition, the handling cylinder is opened together with the handling room top plate, and the space where the handling cylinder was present can be used as a space for loading and unloading the receiving net, and the detaching operation can be further simplified.
