Description

[Detailed description of the invention] The present invention is equipped with a constantly driven packer that scrapes the harvested stem culms into a bundling space, and has a plurality of stem culm bundle collection parts arranged in series on the stem culm bundle discharge port side of the bundling space. a primary discharge arm for forming and discharging the bundled stem culm bundles from the binding space toward the collection section;
The reaping and bundling machine is equipped with a secondary discharge arm that forcibly discharges a plurality of bundled stem and culm bundle groups collected in the collecting section to the outside, and the purpose thereof is to control the amount of collected stem culms, the amount of collected stem and culm bundles, When manufacturing multiple types of reaping and tying collectors with different directions of collecting stem culm bundles, etc., it is possible to easily find an appropriate operating trajectory of the discharging arm according to the requirements of each model. The point is to try to fake it.

That is, the reaping and binding collecting machine according to the present invention is characterized in that the drive shaft of the primary discharge arm and the drive shaft of the secondary discharge arm are laterally displaced. In manufacturing multiple types of reaping and bundling machines with different stem culm focusing amounts, stem culm bundle collection amounts, collected stem culm bundle release directions, etc., the drive shaft of the primary discharge arm and the secondary discharge arm are Since the mounting position of the drive shaft can be freely set according to the requirements of each model, for example, the drive shafts of both ejection arms will not interfere with each other, as would be the case if they were installed on the same axis. There are no restrictions in terms of structure or assembly to achieve such an operating trajectory, and it is possible to easily create an appropriate operating trajectory for the discharging arm according to the requirements of each model, and to achieve the desired bundling and collection. We have now achieved a reliable and good release effect.

Hereinafter, an embodiment 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,
1 and a traveling control handle 2.
A device 3 for pulling up the planted stem culm backwards and upwards and a clipper type reaping device 4 for cutting the base of the planted stem culm that has been pulled up are arranged in front of the plant, and immediately behind the cutting device 4, A binding device 5 that binds and discharges the harvested stem culms in a fixed amount at a location near the plant base in an almost vertical position.
The binding space 6 is provided in a state in which the binding space 6 is open in the front-rear direction at or approximately at the center in the cutting width direction of the reaping device 4, and the reaped stem culm is provided below the terminal end of the pulling device 3. A rotating body 7 is disposed to push into the binding 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 4, a constantly driven pucker 9 is installed on one side of the bundling space 6 to push 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 bundled, and a binding cord supply needle 11 that is driven by one rotation based on the sensing operation of the door 10 are provided, and on the other side, the A mechanism 12 for knotting the binding string supplied from the needle 11, a primary discharge mechanism 13 for forcibly releasing the tied stem culm bundles in the binding space 6 into the collecting section 8, and A secondary release mechanism 14 for forcibly releasing a plurality of stem and culm bundle groups laterally and laterally.
has been set up.

In order to install the knotting mechanism 12, the primary discharge mechanism 13 and the secondary discharge mechanism 14, a transmission case 16 fixedly connected to the transmission vertical case 15 to the pulling device 3 is synchronously interlocked with the needle 11;
and an intermittent drive shaft 18 projecting upward from the binding case 17 of the binding device 5, a drive shaft 19 of the knotting mechanism 12, and a drive shaft 2 of the secondary release mechanism 14.
0 is supported with each of these drive shafts 18, 19, and 20 being displaced laterally relative to each other, and the primary discharge is carried out on shaft portions of the intermittent drive shaft 18 located on both upper and lower sides of the transmission case 16. While fixing the pair of release arms 13A, 13A of the mechanism 13,
The intermittent drive shaft 18 and the drive shaft 19 of the knotting mechanism 12
This drive shaft 19 and the drive shaft 20 of the secondary discharge mechanism 14 are interlocked via transmission chains 21 and 22, respectively, and a transmission system from the knotting mechanism 12 to the secondary discharge mechanism 14 includes a , automatically based on the detection result of the sensor 23 that detects that a predetermined amount of stem culm bundles have been collected in the collection unit 8, and
A one-turn clutch 24, which is reversibly engaged and actuated, is interposed.

The secondary discharge mechanism 14 is constructed as follows.

A member 27 for slidably inserting and supporting the intermediate portion of the secondary discharge arm 26 is pivotally attached to the eccentric portion of the drive rotary body 25 fixed to the upper end of the drive shaft 20. One end is pivotally connected to one end of a reciprocating swinging arm 28 which is pivotally connected to a fixed part on the side of the rotation path of the driving rotary body 25, and another link 29 is pivotally connected to the driving rotary body 25. The end thereof is pivotally connected near one end of the reciprocating swinging arm 28, so that the secondary discharge arm 26 can be moved by cranking movement accompanying the driving rotation of the driving rotary body 25 and sliding movement with respect to the supporting member 27. Accordingly, the collecting section 8 is configured to perform forced circulation movement.
