Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combine side divider device which is disposed on the left and right outer sides of a combine machine to prevent uncut grain culms from coming into contact with the machine and being drawn into the machine during mowing work.

[0002]

[Prior art]

 For example, in the case of a divider arranged on the left side of the mowing section, a divider whose front end side is used as a fulcrum of rotation and whose rear end side is horizontally and vertically adjustable in the horizontal and vertical directions is supported by the machine body. is there.

[0003]

[Problems to be solved by the device]

 However, in the case of the above-mentioned conventional means, the front end side of the divider is supported only in one direction up and down or left and right around the fulcrum shaft, and it is difficult to smoothly follow the movement in the other direction. There was a problem.

[0004]

[Means for Solving the Problems]

 Therefore, in the present invention, in the structure in which the side divider is arranged outside the machine body, the rear end side of the divider is supported by the machine body so as to be vertically and horizontally movable, and the front end of the divider is vertically and horizontally rotatable on the rotation fulcrum portion of the machine body. By supporting the divider in the left and right directions and the upper and lower directions in a smooth manner at the front and rear ends, the divider can be stored and adjusted in a very convenient manner.

Vertical transfer chain (29) that inherits and transfers the start end of the vertical transfer chain (29) The feed chain (5) is provided above the terminal end and is provided with an auxiliary transfer chain (30) for inheriting the grain culms in a proper posture, and the grain culms cut by the cutting blade (9) are provided in each chain (26). The feed chain (5) is passed through (29) and (30) and supplied to the threshing unit (4) for threshing treatment.

As shown in FIGS. 5 to 7, a front and rear separation type is provided at a lower left outer position of the threshing part (4) and the mowing part (8) to prevent uncut mow culms from being drawn inside the fuselage. The threshing and mowing side dividers (31) (32) are arranged, along the left outer side of the threshing section (4), through the support arm (33) to the machine stand (3) over the entire length of the threshing section (4). The threshing side divider (31) is supported, and two front dividers (34) and rear dividers (35) that constitute a cutting side divider (32) are arranged on the front left outer side and the rear left outer side of the cutting unit (8), respectively. It is configured to be installed.

Then, the rear end of the front divider (34) is attached to the central fulcrum frame (37) projecting to the left outside of the left end drive case (36) of the mowing triaxial for transmitting the driving force to the cutting blade (9) and the like. And the front ends of the rear dividers (35) are respectively supported, and the front ends of the front dividers (34) are supported by the raising and connecting pipes (38) at the front of the mowing frame (12), and the threshing side dividers (31) The rear end of the rear divider (35) is configured to be suspended at a substantially middle portion.

The fulcrum frame (37) includes an L-shaped bracket (40) fixed to the left side surface of the drive case (36) via a bolt (39), an up-down adjustment plate (41), a cylinder shaft (42), and It is supported movably up and down and left and right via a left and right regulating plate (43). One end side of the adjusting plate (41) is attached to the bracket (40) via a fulcrum shaft (44), and the adjusting plate (41) The middle part is attached through the long hole (45), the adjustment bolt (46) and the crimping spring (47), and the adjustment plate (41) is pivotally adjustable about the fulcrum shaft (44) and positioned on the bracket (40). The tubular shaft (42) and the regulating plate (43) are integrally fixed to the other end side of the adjusting plate (41), and are fixed to the tubular shaft (42) and the regulating plate (43). (37) is supported so that it can move left and right, The fulcrum frame (37) is fixed to the plate (43) by a positioning pin (48) so that the fulcrum frame (37) can be projected or housed.

Further, the outer end of the fulcrum frame (37) is formed on the flat plate mounting portion (37a), and the U-shaped engaging portion (34a) at the rear end of the front divider (34) and the flat end of the front end of the rear divider (35). The plate-shaped mounting portion (35a) and the mounting portion (37a) are connected by a pivot bolt (49), and the rear end of the front divider (34) and the front end of the rear divider (35) are vertically moved by a fulcrum frame (37). And is configured to be moved and adjusted left and right.

Further, the divider (34) is provided as a double shaft structure in which the front end side is formed by the outer shaft (34b) and the rear end side is formed by the inner shaft (34c) so as to be expandable and contractible, and as shown in FIG. The L-shaped stay (52) is rotatably mounted on the protrusion (50), which is a pivotal fulcrum portion on the left outside of the connecting pipe (38), via a bolt (51), and the other end of the stay (52) is attached. The pin hole (53) is engaged with a left-right rotation fulcrum pin (54) projecting from the front end of the front divider (34) to allow the fulcrum frame (37) to move the left and right sides of the front end of the front divider (34). Also, it is configured so that the front end side can follow these movements when moving up and down.

Furthermore, the rear end of the rear divider (35) is bent to form a hook portion (35b), and the threshing side divider (31) engages with and supports the hook portion (35b) from above. The rigidity is improved by shortening (35). In this case, the hook portion (35b) may be replaced with a ring-shaped engaging structure that is fitted to the outer circumference of the threshing side divider (31).

The present embodiment is configured as described above, and is a front and rear separation type with the threshing and cutting side dividers (31) (32), so that the length of each one divider (31) (32) is increased. It is possible to improve the rigidity and support strength of each divider (31) (32) by shortening the height.

Further, in the front divider (34) of the side divider (32) arranged on the left outer side of the reaping section (8), the rear end side is moved by the fulcrum frame (37) vertically and horizontally. When operated, the front end side can also follow these two-direction movements to facilitate smooth movement adjustment of the entire front divider (34) in the vertical and horizontal directions, and thus the cutting side divider (32). It is possible to smoothly adjust the mounting height position of, and store and expand.

FIG. 8 shows another modified structural example of the front end supporting portion of the front divider (34), which has a rotary fulcrum portion projecting to the left outer side of the connecting pipe (38). The axial bolt (56a) of the link ball portion (56) of the front end of the front divider (34) which can be freely oriented is connected and fixed to the bolt hole (55) of the horizontal protrusion (50a), and the axial bolt (56a) is fixed. The link ball portion (56) as a center is configured to easily allow the front divider (34) to move in the left-right (a) direction and the up-down (b) direction.
