Description

[Detailed description of the invention] The present invention includes a cutting device for shredding the waste culms transported in a posture perpendicular to the transport direction, and a binding device for binding and discharging the rice culms. This relates to culm processing devices arranged in parallel in a direction orthogonal to the direction.

In this type of waste culm processing equipment, both ends of the waste culm enter the cutting device and the bundling device almost simultaneously, so when cutting the waste culm, when both the cutting device and the bundling device are operated, the cutting The culm is raked and housed by the raking rod of the device and the packer of the tying device, but the stock base is accumulated between the packer of the tying device and the T projection, and the T projection is activated to remove the needle, knotter bill portion, etc. Before operating
In other words, the culm is bent by the scraping rod and drawn into the cutting device before pressure is applied to the T projection.

When the culm was pulled in by the rake rod, there was a risk that the binding string suspended between the needle and the Notterbill device would get caught on the culm and be drawn into the cutting device.

In the present invention, a gap is provided at a position in front of the T-protrusion in the culm exit passage, through which the binding string can pass, in a swinging piece that is swingably pivoted to the platform and whose lower end can freely touch the floor. The purpose is to prevent the binding string from getting caught on the culm and being drawn into the cutting device during the cutting operation by restraining the binding string using the edge of the swinging piece in this gap. be.

Further, 135, 135 is a platen fixed to the platform 45 at a position forward of the T projection 51 in the culm passageway 43) 137.137. . . . are rocking pieces pivotably pivoted by shafts 139, 139, and are arranged side by side with a gap 141 through which the binding string 68 can pass, and their lower ends are provided so as to be able to come into contact with the floor surface 41. It is being

Reference numeral 143 denotes an elastic device that is locked between the platform 45 and the swinging piece 135, and urges the swinging piece 135 in the direction of contacting the floor surface 47 with an appropriate elastic force.

In the above configuration, in order to shred and discharge the threshed culm by the threshing section (not shown), a clutch (not shown) interposed between the raking drum shaft 21 and the sprocket 125 is used. When connected, both the binding device 15 and the cutting device 13 operate.

The culm conveyed by the straw removing ch 79 enters the culm passageway 43 by being raked in by the packer 49 on the plant side and by the raking rod 23 on the tip side.

The scraping rod 23 bends the waste culm at a position close to the center, draws it between the scraping drum 19 and the rotor 29, and sequentially cuts the culm from the end with the blade 37 of the cutter 33, and opens it with the opening/closing lid 39. It is discharged to the ground through the opening 40.

In this case, in the bundling device 15, the base side of the culm being scraped by the packer 49 is pulled in by the scraping rod 23 before being accumulated between it and the T projection 51.
No predetermined force is applied to the T-protrusion 51, and the needle 67 and knotter bill portion 69 do not act.

Also, among the binding strings 68 shown by the chain lines in FIG. The state on the left side in Figure 3, pushed by the culm, and the state on the 6th side
As shown in the figure, it enters the gap 141 of the swinging piece 135,
The swinging piece 135 takes a recessed position from the front side in the culm transfer direction.

However, in FIGS. 3 and 6, the culm that pushes the binding string 68 is not shown.

Therefore, when the culm is retracted by the rake rod 23,
Since the stock side is pulled in in a direction perpendicular to the gap 141, the binding string 68 is attached to the swinging piece 135 in the gap 141.
The culm is restrained by the edge of the culm, and it is less likely to be drawn in together with the culm.

□When tying the culms,
When the clutch (not shown) between the raking drum shaft 21 and the sprocket 12.5 is disconnected, the raking drum 19 stops with the raking rod 23 submerged from the floor surface.

The culm sent by the straw removal check 79 is sent to the packer 4.
9, it is pushed into the housing between the T-protrusion 51, and when it reaches an appropriate amount, it presses the T-protrusion 51 with a predetermined pressing force, and when the T-protrusion 51 swings slightly, a clutch (not shown) is activated. Then, the needle 67 rotates to wrap the binding string 68 around the culm and feed it into the string holder 11.

Next, the knotter bill part 69 ties and cuts the binding string 68, and at the same time, the T-protrusion 51 swings and retreats, and the bundled discharged culm bundle is pushed onto the discharge chain 77 by the discharge rod 75 and discharged to the ground. It is something.

In this case, the binding string 68 in the culm passage 43 is connected to the swinging piece 13.
Since it passes through the gap 141 of No. 5, it is not obstructed by the swinging piece 135.

In addition, the culm pressed by the packer 49 is
5 and is pressed between the T protrusion 51 and the T protrusion 51.
is activated, and is bound by a binding string 68 in the gap 141.

As is clear from the above, according to the configuration of this invention, when pulling the culm into the cutting device and performing cutting work,
The tying string is pushed by the culm and enters the gap between the swinging pieces, so even if the tying string gets caught on something other than the culm when the culm is being pulled into the cutting device, the tying string will Since the length of the binding string is regulated by the edge of the rocking piece gap, the length of the binding string can be reduced.

Therefore, the binding string is less likely to be drawn into the cutting device, and the cutting operation can be performed more smoothly.
