Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention collects grain bundles sent laterally outward from a binding device, and when the collected grain bundles reach a predetermined amount,
The present invention relates to a grain culm bundle collecting and discharging device for a binder configured to release grain culm bundles by opening a door, and more particularly to a technique for sending the grain culm bundles placed on the deck to the rear.

[Conventional technology]

Conventionally, as the above-mentioned technology, for example, Utility Model Application No. 55-14932
As shown in Publication No. 6, the conveyance path of the lateral conveyance belt provided on the binder is extended to the side of the machine body, and the conveying action of the belt carries the grain bundles sent out from the binding device onto the deck. There is one configured to send it backwards.

[Problem that the invention seeks to solve]

However, as in the above-mentioned example, in a structure in which a horizontal conveying belt is extended to send the grain bundles on the deck, the structure in which the conveying force acts on the grain bundles from the side causes the binding device to If the volume of the grain bundle sent out from the belt is small, the grain bundle and the belt may become separated and the grain bundle cannot be fed sufficiently.

In addition, in the cited structure, since the horizontal conveyor belt is constantly driven, when a predetermined amount of grain bundles are collected on the deck, just before the grain bundles are released, the collected grain bundles and the horizontal In some cases, the conveyor belt comes into contact with the conveyor belt, reducing the conveyance force of the horizontal conveyor belt.

An object of the present invention is to rationally configure a structure for reliably and effortlessly sending grain bundles sent out from a binding device to the rear.

[Means for solving problems]

The present invention is characterized in that a grain culm bundle collecting and discharging device having a snow raising configuration is provided with a mechanism for sending the grain culm bundle sent out from the binding device further rearward from the position where the grain culm bundle was sent out, and that the mechanism The drive system of the mechanism is configured to reciprocate approximately back and forth in synchronization with the operation of the device, and its functions and effects are as follows.

[For production]

For example, if the features of the present invention are configured as in the following embodiments,
