Description

[Detailed description of the invention] The present invention has a binding device that binds harvested stem culms in an upright position, with a device attached to the lateral outer side of the body on the bundle release side that can freely swing up and down using its front end as a fulcrum. A grounding deck that receives and supports the plant base in contact with the ground and transports and guides the plant base rearward due to ground resistance; The present invention relates to a reaping and tying machine equipped with a stem and culm bundle collection device equipped with a tip receiver that releases supporting stem and culm bundles by swinging.

In conventional reaping and binding machines of this type, the grounding deck was configured so that it could freely swing up and down, but when this was used, it ensured contact with the ground at the base of the receiving stalks and culms, and reduced the resistance due to ground resistance. In order to ensure and smooth rearward feeding of the stem culm bundle, if the stock head receiving part of the deck is configured to be narrow, when the deck rides on a large protrusion on the ground, the narrow stock base receiving part of the deck will The base of the receiving stem culm bundle swings upward as if biting into the space between the stem culms of the receiving stem culm bundle, and the base of the receiving stem culm bundle protrudes significantly below the deck. The base of the stem culm bundle, which protrudes greatly, is bent backwards, and this bending action spreads to the entire stem culm, causing the stem culm bundle to fall forward, and when the tip receiver is swung downward to release the stem culm, the stem culm This method has the disadvantage that it tends to cause problems such as the bundle getting caught on the deck or the tip holder, making it impossible to release the bundle reliably.

The purpose of the present invention is to overcome these conventional drawbacks.

The reaping and tying machine according to the present invention is provided with a swing regulating member that can contact and prevent the above-mentioned grounding deck from swinging above a certain level due to a ground reaction force in a state that can be released from the blocking, and the above-mentioned grounding deck is also provided with a swing regulating member that can be released from the blocking. The device is characterized in that it is provided with a mechanism that can hold the position at a position above the blocking position in the state.

Therefore, according to the characteristic configuration of the present invention, even if the deck rides on a large protrusion on the ground during cutting and tying work, the swing regulating member prevents the deck from moving above a certain level due to the climbing. Since it is possible to prevent movement, the stock receiving part in the deck is configured to have a narrow width to ensure the contact of the receiving stem culm bundle with the ground, and to facilitate the backward feeding of the receiving stem culm bundle due to the ground resistance. , Even if a configuration is adopted that can ensure this, the amount of protrusion of the receiving stem culm bundle below the deck can be minimized by suppressing the biting of the stem stem receiving part into the space between the stem culms. As a result, the stem culm bundle can be received and supported in a stable posture without causing bending of the base of the receiving stem culm bundle or forward falling of the receiving stem culm bundle due to ground resistance. The release of the receiving stem culm bundle can be performed smoothly and reliably. Moreover, since the swing regulating member is capable of releasing the blocking and is provided with a mechanism capable of holding the deck in a position above the blocking position in the blocking release state, the deck can be held in the upward position. By keeping the deck floating above the ground during non-work driving such as on the road,
It is possible to reduce running resistance, suppress wear on the deck, and when the aircraft is moving backwards, it prevents the rear end of the deck from hitting the ground as the aircraft moves backwards, preventing deformation and damage to the deck. .
