Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a method of receiving and supporting the base of the released stem culm bundle in contact with the ground on the lateral outer side of the machine body on the bundle release side of a binding device that binds reaped stem culms in an upright position. and a deck that moves and guides the base of the stem culm bundle rearward by the ground resistance acting on the base of the stem culm bundle as the aircraft moves forward, and a posture in which the tip side of the ejected stem culm bundle is slumped toward the lateral outside of the aircraft. A stem culm bundle collecting and discharging device is provided, which comprises a panicle tip receiver that receives and supports the stalk and culm bundles, and an automatic release mechanism that opens the panicle tip receiver in a receiving release direction when a set number of stem and culm bundles are collected. It concerns a certain binder.

Conventionally, the deck of the stem culm bundle collecting and discharging device receives and supports the stem part of the stem culm bundle moving rearward from the rear by bending its rear end upward, and the stem part receives and supports the stem part from the rear. This prevents the stalks from slipping out of the deck backwards and disrupting the collection posture, but when the tip receiver is released after a predetermined number of bundles have been collected and the stem and culm bundles fall sideways to the outside and are released, they fall sideways onto the field. The stem base of the stem culm bundle placed on the deck may remain stuck on the deck, and in such a case, as the aircraft moves forward, the upward bent part of the rear end of the deck may fall sideways and the stem of the stem culm bundle may fall. There were cases where the base was caught and pushed forward, disrupting the stacking posture of the bundle.

Of course, if the upward bending of the rear end of the deck is small, this problem will be reduced, but on the other hand, it will be more likely that the base of the plant will come off the deck during collection, and the nature of the stem culm and the bundle Since the receiving function and degree of hooking of the stock base vary greatly depending on various conditions such as size, it is extremely difficult to set the bend at the rear end of the deck. Also, even if the degree of bending is changed and adjusted to achieve an appropriate stock-receiving function with less hooking,
The adjustments are frequent and will require frequent adjustments.

The present invention has focused on such a situation, and while reliably preventing the stock head part from coming off the deck backwards during collection, it also prevents the stock head part of the discharged bundle from falling sideways and resting on the deck when the collection bundle is released. The object of the present invention is to provide a binder that can move the aircraft forward without hooking and disturbing the ejected stem culm bundle, and in the binder having the above configuration, a portion directly above the vicinity of the rear end of the deck is provided. A stock base receiver is provided at the position to receive and support the stock base of the stem culm bundle that has been moved backward due to ground resistance from the rear, and this stock base receiver is
It is characterized in that an interlocking mechanism is provided for retracting from the stock head receiving position in synchronization with the opening operation of the tip receiver.

According to the above characteristic configuration, no matter what the nature or size of the stem culm bundles to be collected, the stem base receiver located near the rear end of the deck and directly above the stem can collect the stems moving backward. I am now able to collect the bundles in a good posture, catching them securely and not letting them fall off the deck. However, since this stock head receiver is evacuated from the stock head receiving position when releasing the collected bundle,
To smoothly move and pass only the deck along with the machine body while placing the stem and culm bundle released sideways in a predetermined sideways posture in the field even if the stock base of the released bundle is placed on the deck. was completed. As a result, it has become possible to align all the stem and culm bundles placed and released in the field into a desired sideways posture, and to easily carry out the subsequent collection work.

Embodiments of the present invention will be described below based on illustrative drawings.
