Abstract

PURPOSE:To prevent damage, etc., of a changeover plate by changing over a changeover mechanism for carrying out changeover from a state of discharging cut waste straws to a state of discharging uncut waste straws to the state of discharging the uncut waste straws following opening operation of a cutter. CONSTITUTION:A conveying passage part of a waste straw conveyor 3 is provided with a changeover mechanism 6 for carrying out changeover from a state of discharging cut waste straws to a state of discharging uncut waste straws. A changeover plate (6a) is supported on a cutter frame 7 so as to freely rise and fall and rotate around a shaft center (P1) of a transverse shaft (6b). When the cutter is rocked and opened with a longitudinal shaft 15 as a fulcrum, a rod 19 is separated from a contact state with a machine frame and a changeover arm 9 is slid in the pulling direction of a tensile spring 13 through a slot 20 to rock the rocking arm 8. The changeover plate (6a) is rotated around the transverse shaft center (P1) and charged over to falling direction for closing the inlet part of the cutter.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a waste straw processing device for a harvesting machine such as a combine harvester or a harvester.

[Prior art and problems]

As a device for processing the waste straw after being removed, a technique is already known in which a switching device is provided in the wandering straw transport path to switch the feeding and supply of the waste straw between the cutter side and the rosova side.

Furthermore, in order to facilitate maintenance, a technique is known in which the cutter can be pivoted open and closed using one end as a fulcrum.

Conventionally, when the cutter is swung open, if the switching plate remains in the switching state during cutter operation, there has been a problem that the switching plate interferes with the waste straw conveying device, leading to deformation and damage.

The present invention aims to solve the above problems by configuring the switching plate to switch to the dropper side when the cutter swings open and close.

[Question 1rf1. Means for determining) The technical means of the present invention is to transfer waste straw from the threshing section to a waste straw conveying device l'''1.
A first processing state in which the straw is fed into a saw cutter 4 provided at the terminal end of the cutter 4 to be cut and released into the field, and a second processing state in which the straw is discharged into the field as a long straw after passing through the cutter 4 in the 1st direction. The switching mechanism 6, which can be switched to 11f, is set to 11,
1. The cutter 4 is configured to be able to swing open and close using the one side end 4+11 as a fulcrum, and when the cutter is opened, the switching mechanism is switched to the second processing state. This feature is characterized by the provision of a mechanism 17 for causing this.

[Function and effect of the invention]

That is, according to the configuration of the present invention, when the cutter swings open, even if the switching mechanism that switches between the cut waste straw release state and the uncut waste straw release state is in the switched state to the cut waste straw release state, Due to the opening operation of the cutter, the IJ
Since the IRJ can be switched to the uninterrupted straw discharge state, it has become possible to eliminate the problem of the conventional method that interferes with the switching plate or the straw removal conveying device "1', which causes deformation and damage of the unhaU U." .

〔Example〕

Hereinafter, ten embodiments of the present invention will be described with reference to the drawings.

The waste straw sent to the rear of the machine from the hat removal section 1 of the combine via the foot chain 2 and the waste straw transport device 3 is fed into a cutter 4 provided below the terminal end of the wandering straw transport device 33 and cut. There is a first processing state in which the straw is discharged into the field, and a first processing state in which the long straw is sent beyond the cutter 4 side 1 to the bundle cutter 119r and is collected and discharged into the field. A switching mechanism 6 with +11 switching functions is included! It is provided in the transport path section of the Ir straw transport device Hi4ε3. In this 91 switching mechanism, a switching plate 6a is attached to the cutter frame 7 at an axis P of a horizontal shaft 6b.

It is a rack that can be raised and rotated freely around the 6
] occurs in the passage 1 to the cutter 5 side/\ in the 1st process state J & J of 111j, and in the first process state, the 11 part of the cutter 47\ is It is configured to lie face down in a closed position.

Moreover, this switching plate 6d includes a swing arm 8, a switching arm 9,
It is configured to be interlocked so that switching +11 can be performed via the operation Y-Y-10. The swing arm 8 has a base connected to the switching plate 6a.
The switching arm 9 is fixed to the horizontal shaft 6b, and its tip is supported on one end side of the switching arm 9 via a pin @11. Switching arm 9
The middle part is suspended with respect to the cutter frame 7 so as to swing around the axis P7 of the holding f-axis 12, and the tension spring 1
; 3 is configured to always bias the switching plate Ga in the direction of lying down.

On the other hand, the cutter 4 is attached to the machine frame 14 on the machine side so that it can swing open and close at a vertical axis L5&':M point on the - side end side in the downward direction.

When the cutter 4 is opened, a mechanism 17 is provided which switches the switching plate 6a from the first processing state to the second processing state based on the opening operation.
In the embodiment shown in FIGS. 2 to 4, one end of the mechanism 17 contacts the machine frame 14 on the machine side when the cutter 4 is in the closed state, and the other end contacts the machine frame 14 on the machine side. II KaMi+ AiE cut m7-m9 (7) Inserted into the middle fl11 part notaIIllIII2 and supported by the guy 11 member ``8'', sliding 11! It is constituted by a switching rod 19 that can be switched. The transverse shaft 12 portion of the intermediate portion of the tlII exchange arm 9 is constructed as a shaft so that it can slide in the biasing direction of the tension spring 123 via the elongated hole 20.

Therefore, when the switching plate 6a is in the first processing state, when the cutter 4 is opened in a motion with the vertical shaft 15 at one end as a fulcrum, the rod 19 is moved from the state of contact with the machine frame 14 to Aflt 171. , the switching arm 9 has a long hole 20
The swinging arm 8 swings in the direction of the notch through the tension spring 13, and the switching plate 6d swings around the horizontal axis I) to rotate the cutter 4 in the direction in which the cutter 4 is pulled. -It can be switched to the lying direction that closes off the first part. On the other hand, cutter 4
When the rod 19 is closed, the tip of the rod 19 comes into contact with the machine frame 14 and swings, so that the switching arm 9 uses the connecting part to the operating wire S710 as a fulcrum and resists the tension spring 13 through the elongated hole 20. The swinging arm 8 swings in the opposite direction of arrow A, and the switching plate 6Q returns to its original upright position 7.

Next, another embodiment shown in FIGS. 5 and 6 will be described. The switching arm 9 is supported by being fixed to the machine frame 14 on the machine side by pushing and pulling the operating wire 1o connected to the manual switching lever. It is pivotably supported around a connecting pin 22 in the seven-down direction with respect to the tool 21 .

Swing arms 23 and 24 are fixed to the horizontal shaft 6b of the switching plate 6a, and one of the swinging arms 23 is urged by a tension spring 1; 3 in a direction in which the switching plate 6a is always laid down. The other swing arm 24 has a rod 19 movably installed on a guide member 18 fixed to the cutter frame 7 side, and one end of which is held in contact with the switching arm 1.9.
The other end is connected.

The cutter 4 is moved around the vertical axis 15 by 1. = fi Mi
When l+ is released, the rod -9 held in contact with the switching arm 9 is connected to the switching arm jX9.
To +xlt till and become free,
The switching plate 6a is subjected to the tensile action t by the tension springs 1 and 3.
He was hit hard and fell face down.
