ごとの収集放出が行なわれるのである。 DETAILED DESCRIPTION OF THE INVENTION The present invention provides a primary discharge mechanism for discharging bundled stem culm bundles outward from the binding space, and a plurality of stalk culm bundles arranged in series on the stalk culm bundle discharge opening side of the binding space. A reaping and bundling harvester is provided with a secondary discharge mechanism for forcibly discharging a group of collected stem culm bundles in a collection section to the outside, and a clutch is interposed in a transmission mechanism from the primary discharge mechanism to the secondary discharge mechanism. . This type of reaping and tying harvester is provided with a mechanism that detects the collection pressure of the stem culm bundles collected in the collection section and automatically engages and operates the clutch when the detected collection pressure reaches a set value. However, in this case, if the diameter of the tied stem culm bundle differs depending on the variety of stem culm or the degree of growth,
In particular, when the diameter is smaller than the standard diameter, the clutch is not activated even though a predetermined number of stem bundles have been collected in the collecting section, and as a result, the next bundled stem culm bundle is moved to the collecting section side. The clutch is engaged and activated only when the collected stem culm bundles are released, which not only causes variations in the number of collected stem culm bundles released and the released position, but also tends to put strain on the primary release mechanism and the collecting pressure detection mechanism. If the collected stem culm bundle extends to the boundary between the bundling space and the collection section, the discharge arm of the secondary discharge mechanism will not only cause damage to the collected stem culm bundle, but also cause damage to the collected stem culm bundle. However, there was a problem in that this secondary release mechanism could not perform the intended release action of the collected stem culm bundle group. In view of the above-mentioned circumstances, an object of the present invention is to make it possible to reliably avoid the above-mentioned release troubles caused by variations in the number of collected bundles of bundled stems and culms. That is, the reaping and tying harvester according to the present invention includes a mechanism that detects the number of times the primary discharge mechanism is operated and automatically engages and operates the clutch when the detected number of times reaches a set value. It is characterized by the fact that a predetermined number of stem and culm bundles can always be reliably collected in the collecting section regardless of variations in the diameter of the bundled stem and culm bundles. , the collected stem culm bundles in the collection section are reliably released by the secondary release mechanism without causing variations in the number and release posture of the collected stem culm bundles, and without overloading the primary release mechanism; It has now been possible to release it. Hereinafter, embodiments of the present invention will be described for a single-row type binder. As shown in FIG. 1, a pair of left and right running wheels 1,

A rotary body 7 is arranged to scrape into the space 6. Further, the binding device 5 has a discharge port 8a on the stem culm discharge port side from the binding space 6, which passes between the binding device 5 and the running wheels 1, 1 and opens to one side. A collecting section that can collect and hold a plurality of stem culm bundles in a row in the front-rear and left-right directions in an almost vertical position by providing a stem culm mounting deck 8A in a wide space in a direction perpendicular or almost perpendicular to the discharge direction. 8. The binding device 5 is constructed as follows. As shown in FIGS. 2 to 5, on one side of the bundling space 6, there is a constantly driven pucker 9 that scrapes the cut stem culms into the bundling space 6, and a set amount of A door 10 that senses that the reaped stem culms are collected, and a knotting string supply needle 11 that is driven by one rotation based on the sensing operation of the door 10 are provided. a knotting mechanism 12 synchronously coupled to;
A primary release mechanism 13 that synchronizes with this knotting mechanism 12 and forcibly releases the bundled stem culm bundles in the binding space 6 into the collecting section 8; A secondary release mechanism 14 is provided for forcibly releasing the culm bundle group laterally and outwardly. Further, a clutch 15 is interposed in the transmission mechanism from the primary release mechanism 13 to the secondary release mechanism 14, and an upper release arm 13A of the pair of upper and lower release arms 13A of the primary release mechanism 13 is provided. A mechanism 16 is provided which detects the number of actuations of the primary discharge mechanism 13 by contact with the primary discharge mechanism 13 and automatically engages and operates the clutch 15 when the detected number of times reaches a set value. The primary release mechanism 13 includes a shaft portion of an intermittent drive shaft 17 to the knotting mechanism 12 located on both upper and lower sides of the knotting mechanism 12.
A, 13A are fixedly attached, and the discharge action portions of both primary discharge arms 13A, 13A are configured to escape from the collecting section 8 and swing during the latter half of the culm discharge operation. The secondary discharge mechanism 14 is constructed as follows. A member 20 for slidably inserting and supporting the intermediate portion of the secondary discharge arm 19 is pivotally connected to the eccentric portion of the drive rotor 18 that is loosely fitted to the upper end of the intermittent drive shaft 17, and One end of the secondary discharge arm 19 is pivotally connected to an arm 21 that is pivotable in a reciprocating manner and pivoted to a fixed part on the opposite side of the collecting part 8 at the arm side of the rotation path of the driving rotary body 18, and further, The drive rotating body 18 and the reciprocating swing arm 2
1 through a rod 22, and
The secondary discharge arm 19 is connected to the drive rotating body 18.
The structure is such that the inside of the collecting section 8 is forced to undergo a forced circulation movement by the crank movement accompanying the drive rotation and the sliding movement with respect to the slide support member 20. The clutch 15 is constructed as follows. A clutch operating piece 25, which has a roller 24 pivotally attached to the tip of a pin 23 fixed to the boss portion 18A of the driving rotary body 18, is brought into contact with a cam 26 fixed to the upper primary discharge arm 13A, The primary discharge arm 13A and the drive rotary body 18 are swingably switched between a clutch engaged position where the primary discharge arm 13A and the drive rotary body 18 rotate integrally around the axis of the intermittent drive shaft 17, and a clutch disengaged position where the clutch is retracted toward the intermittent drive shaft 17 side. A spring 28 is interposed between the clutch actuating piece 25 and the boss portion 18A to bias the clutch actuating piece 25 toward the clutch engaged position. In this case, the clutch actuator 30 is fitted which can engage the clutch actuating piece 25 and hold the clutch actuating piece 25 at the clutch disengaged position against the biasing force of the spring 28. There is. The mechanism 16 is constructed as follows. The swing fulcrum shaft 29 is capable of coming into contact with a cam 31 erected on the upper primary discharge arm 13A;
