Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a primary discharge mechanism for discharging bundled bundles of stalks and culms outward from the binding space, and a plurality of stalk and culm bundle collectors arranged in series on the stalk bundle discharge port side of the binding space. The present invention relates to a reaping and tying collector equipped with a secondary discharge mechanism that forcibly discharges a group of collected bundles inside the unit to the outside. In the reaping band collecting machine having such a configuration, conventionally, in order to drive both of the discharge mechanisms, a transmission system to the primary discharge mechanism and a transmission system to the secondary discharge mechanism are constructed separately, and the transmission system to the primary discharge mechanism is separately configured. In the middle of the transmission system, based on the detection result of a mechanism that detects that a predetermined amount of cut stem culms are collected in the bundling space,
and a reversibly engaged and actuated clutch, and
In the middle of the transmission system on the side of the secondary discharge mechanism, there is a clutch that is automatically and reversibly engaged and activated based on the detection result of the mechanism that detects that a predetermined amount of stem culm bundles have been collected in the collection section. However, in this case, if there is a variation in the convergence diameter of the stem culm due to differences in the variety or growth rate of the stem culm, the clutch of the primary release mechanism and the secondary release There is a difference in the timing of the mechanism's engagement with the clutch, and as a result, these two release mechanisms interfere with each other, or the stem culm bundle that is forcibly released from the binding space is released by the secondary release mechanism. There were also problems in terms of release action, such as the release of the product directly to the outside through the release port of the collection unit, which was likely to cause various troubles. In view of the above-mentioned circumstances, it is an object of the present invention to enable the above-mentioned two release mechanisms to always reliably and satisfactorily exhibit the intended release action. Based on the detection result of a mechanism that detects that a predetermined number of stem culm bundles have been collected in the collecting section, in a transmission mechanism for synchronizing and interlocking the primary release mechanism and the secondary release mechanism. It is characterized by the interposition of a clutch which is automatically and reversibly engaged and actuated. That is, in the case of the present invention, if the primary release mechanism is not in a driving state, even if the clutch is engaged, the secondary release mechanism will not be driven. Regardless of the timing difference, the primary release mechanism and the secondary release mechanism can be reliably synchronized, and the desired stem culm bundle release action by both release mechanisms can be ensured without causing the above-mentioned troubles. , I was able to get it to work well. In addition, when the detection mechanism is configured with a release arm of the secondary release mechanism that swings and displaces as it comes into contact with the collection stem culm group, the release arm of the secondary release mechanism is There is an advantage that the detection mechanism can be constructed easily and inexpensively by making effective use of it. Furthermore, if the mechanism for locking the clutch in the engaged state is provided so that the lock can be released freely,
A plurality of stem culm bundles released from the binding space of the bundling device are once collected in a collecting section depending on conditions such as field conditions, the growth status of the harvested stem culms, dryness and humidity, or the collection form after harvesting. Thereafter, there is an advantage that it is possible to conveniently select between a state in which the stem and culm bundles in the collecting section are released into the field in a batch, and a state in which the stem and culm bundles in the bundling space are released into the field in units.
