Description

[Detailed description of the invention] [Industrial field of application] This is a receiving device for a threshing device in which a receiving net can be inserted and removed from the upper part of the handling chamber along the circumferential direction of a circle through a guide section provided inside the handling chamber. Regarding the net fixing structure.

[Conventional technology]

As for the attachment structure of the receiving net in the threshing equipment,
For example, as disclosed in Japanese Utility Model Application Publication No. 55-170942, a structure is used in which a crimp net is stretched over a semi-cylindrical receiving net support frame, and this receiving net support frame is bolted and fixed to the inner wall of the handling room. However, in recent years, in order to facilitate the attachment and detachment of the receiving net, research has begun on a threshing device in which the receiving net is slidably inserted and removed from the upper part of the handling chamber of the threshing device as described above. If such a slide insertion/removal type is adopted, a semi-circular guide part to support the receiving net will be provided inside the handling chamber of the threshing device, and a member for fixing the receiving net will be required, and this member will not fit into the existing tool rest. Therefore, a structure is conceivable in which the tip of the receiving net on the extraction side is pressed and clamped.

[Problem that the invention attempts to solve]

If the structure uses a tool rest as described above, it is necessary to provide a locking mechanism for fixing the tool rest at the clamping position, and a structure in which this locking mechanism is installed on the main body of the thresher is considered. However, with this structure, when taking out the loaded receiving net, the locking member that fixes the tool rest in the clamping position is manually operated to the release side, and then the hand that was holding the locking member is removed from the tool rest. You will need to switch to the turret and remove the turret.

Moreover, when loading the receiving net, the operations must be performed in the reverse order, resulting in a structure that is somewhat difficult from the point of view of ease of handling during maintenance.

The purpose of the present invention is to provide a threshing device that employs a slide-insertion-and-removal-type structure for the receiving net, with a structure that allows the receiving net to be easily fixed and unfixed.

[Means for solving problems]

The feature of the present invention is that the above-mentioned threshing device is provided with a turret for clamping and fixing the leading end of the receiving net on the extraction side in a manner that can be swingably switched between a pressing and clamping position and a pressing and clamping release position. The locking member for fixing the tool rest in the pressing and clamping position is provided on the tool rest so as to be switchable between locking and unfixing, and its functions and effects are as follows.

[Effect]

With the structure described above, when removing the catch net from the loaded state, hold the locking member that fixes the turret in the pressing and clamping position with your hand, operate the locking member to the unlocking side, and then The tool rest can be moved to the grip release position while holding the lock member without changing the grip. On the other hand, when loading and fixing the receiving net, all you have to do is hold the locking member of the tool rest with your hand, move the tool rest to the pressing and clamping position, and then move the locking member to the lock side. There is no need to change hands midway.

[Effect of idea]

As explained above, from the fixing/unfixing operation of the tool post that presses and holds the receiving net at the pressing and holding position, to the switching operation of the press holding and holding release position of the tool post itself,
Alternatively, a series of operations in the opposite direction can be performed continuously without changing hands during the operation, improving ease of handling when inserting and removing the receiving net.
