Next, an embodiment will be described in detail with reference to the drawings. In the drawings, the same reference numerals are used for components having the same effects as those of the conventional means.

FIG. 2 is a side view of the agricultural cutter A embodying the present invention. In FIG. 2, reference numeral 1 denotes a machine frame, a denotes a cutter body mounted on the machine frame 1, and 3 denotes a cutting mechanism for storing a cutting mechanism 2. The casing 30 of the cut chamber is a discharge tube which is integrally or integrally connected to the casing 3 of the cut chamber, and 4 is a discharge gutter which is connected to the discharge tube 30 so as to be tiltable up and down around a connecting shaft S. .

The machine casing 1 is of a stationary type which can be installed at a desired place so as to constitute a stationary agricultural cutter A, but which can be mounted on a vehicle body which is movable by running wheels. May be made.

A cutter body a mounted on the machine frame 1 includes a casing 3 of a cutting chamber for storing a cutting mechanism 2 and a feed roll for feeding a material to be cut into the casing 3 of the cutting chamber. And a supply gutter 3 having a base end connected to a receiving port of the feed roll chamber 32.
3 and a discharge cylinder 30 of the cutting chamber 3 provided so as to protrude shortly from the discharge port of the cutting chamber 3.

The cutting mechanism 2 supplies a rotary blade 22 which is assembled via a blade mounting metal to a main shaft 21 which is supported on the machine frame 1 via a bearing support member 20, and a casing 3 for the cutting chamber. This is a normal type including a fixed blade 23 fixedly attached to the machine frame 1 at the lip portion of the mouth.

The discharge cylinder 30 provided integrally or integrally with the casing 3 of the cutting room has its ceiling wall 302 and left and right side walls 301, 301 integrated with the peripheral wall 3a of the cutting room 3 and the left and right machine walls. The left and right side walls 301, 301 are formed in the same manner as that of the conventional means as an integrally continuous form, but the left and right side walls 301, 301 of the ordinary conventional discharge cylinder 30 shown in FIG. Also, it is extended downward to extend the width in the vertical direction.

The bottom wall 303 of the discharge cylinder 30 is formed as shown in FIG.
As shown in FIG. 3, the base end portion formed separately from the peripheral wall 3a of the casing 3 of the cutting chamber and joined to the front edge of the peripheral wall 3a on the lower surface side of the casing 3 of the cutting chamber is By being pivotally supported on a spindle W arranged between the left and right machine walls of the casing 3 of the cut-off room and arranged at that position, the tip side is freely pivoted up and down around the spindle W center. So that
The left and right side walls 301 are formed to be longer than the left and right side walls 301, and the front ends thereof protrude from the discharge cylinder 30.

The bottom wall 303 of the discharge cylinder 30 is
An engaging piece 305 provided with a bolt insertion hole 304 is provided at each of the left and right ends on the distal end side.
4 and bolt insertion holes 30 selected from bolt insertion holes 306 formed in series on a virtual arc centered on the support shaft W on the left and right side walls 301 of the discharge cylinder 30.
6, by inserting a set bolt 307 and fastening it, as shown by the solid line and the imaginary line in FIG.
The inclination angle of the projecting direction is changed and adjusted.

The discharge gutter 4 is an ordinary one formed by a steel plate into a long downwardly extending channel shape between the ceiling wall 41 and the left and right side walls 40, 40, and has a lower surface opening downward. , Bottom plate 42 formed in an upward channel shape
However, the ceiling wall 41 is formed by the elongated holes 43 and the set bolts 44.
It is attached so that the relative distance to the can be adjusted.

The discharge gutter 4 is formed by connecting a portion of the discharge gutter 4 close to the upper edge on the base end side of the left and right side walls 40, 40 with the connecting shaft S to the left and right side walls of the discharge cylinder 30 of the casing 3 of the cutting chamber. 301 and 301 are rotatably connected to the upper edges, and the portions of the left and right side walls 40 and 40 that are closer to the lower edges on the base end sides are formed as elongated holes 50 along an imaginary arc centered on the connection axis S. The left and right side walls 30 of the discharge cylinder 30 are slidably fitted in the long holes 50.
By connecting with the tightening screw 51 screwed to the first and the first 301, the tightening screw 51 is tightened at a desired rotation position within the range regulated by the long hole 50, so that the inclination angle with respect to the horizontal direction is desired. The fitting hole 7 for fitting with the connection shaft S described above.
Is formed into an arc-shaped long hole, and the connecting shaft S is formed as a tightening screw, so that it can be rotated up and down around the tightening screw 51 as well.

That is, the connecting shaft S is formed as a tightening screw similar to the tightening screw 51 so that the left and right side walls 301.
The fitting holes 7 are screwed into each of the joints 301 and are formed in the left and right side walls 40 of the discharge gutter 4 so as to be fitted to the connecting shaft S. The inclination angle α of the discharge gutter 4 is adjusted by a pair of vertically opposed long holes and tightening screws respectively fitted to the long holes. Even if the length is shortened, the adjustment range of the inclination angle α can be made large.

Reference numeral 6 denotes a discharge gutter connected to the tip of the discharge gutter 4 by a connecting shaft 60, a long hole 61 and a tightening screw 62 so as to be adjustable in inclination angle, which is the same as the conventional discharge gutter.

[0019]

The embodiment of the present invention operates as follows.

When adjusting the inclination angle α of the discharge gutter 4,
By loosening the tightening of the connecting shaft S formed on the tightening screw 51 and the tightening screw, respectively, and sliding the arc-shaped long hole 50 and the arc-shaped fitting hole 7 with respect thereto,
The inclination angle α is changed as desired, and the tightening screw 51 and the connecting shaft S are tightened in this state.

Thus, the adjustment range of the inclination angle α is an angle range corresponding to the sum of the lengths of the long hole 50 and the fitting hole 7. , The range of adjustment of the inclination angle α can be increased.

When the discharge gutter 4 is turned downward to adjust the inclination angle α to a small value, the bottom wall 303 of the discharge tube 30 of the cutting chamber 3 is changed by the re-fitting of the set bolt 306, and the chain line in FIG. As shown in (1), it is turned downward about the support shaft W and set at a position where the inclination angle is reduced.

As a result, the cut material which is cut by the cutting mechanism 2 in the casing 3 of the cutting chamber and discharged from the discharge cylinder 30 has its discharge direction changed to the bottom wall 303 of the discharge cylinder 30. Is changed in a direction along
The inclination angle α is corrected to a direction substantially along the ceiling wall 41 of the discharge gutter 4 and blows out into the discharge gutter 4, and the cut material strongly collides with the ceiling wall 41 of the discharge gutter 4. It will prevent it from becoming scattered.

[0024]

As described above, the discharge device in the agricultural cutter according to the present invention is integrated or integrated with the casing 3 of the cutting chamber so that the discharge gutter 4 is connected to the center of the connecting shaft S so as to be adjustable at an inclination angle α. The discharge cylinder 30 is provided so that the inclination angle of the bottom wall 303 of the discharge cylinder 30 can be freely adjusted. Therefore, when the inclination angle α of the discharge gutter 4 is adjusted to be small, In addition, by changing the inclination angle of the bottom wall 303 of the discharge tube 30, the discharge direction of the cut processing object discharged to the discharge tube 30 provided in the casing of the cutting chamber can be changed and adjusted downward. Therefore, the cut material can be discharged in a state without scattering near the airframe.
