Description

[Detailed description of the invention] The present invention relates to a tall feed cutting machine for cutting tall corn and the like to feed cattle, pigs, etc. (hereinafter referred to as tall feed).

If the reaper is configured by using an agricultural 1-herakta and attaching the reaping mechanism to the attachment 1, the height of the feed is the height of the operator or higher, so the feed with its roots cut off will not be laid down. Post-processing is extremely troublesome.

The purpose of the present invention is to facilitate post-processing and improve cutting efficiency.

A cylindrical tube 4 is integrally fixed to a machine frame 3 that is attached to the agricultural tractor 1 using a hitch box 2 or the like, and a rotary blade 6 is attached to the lower end of a knife shaft 5 disposed within the cylindrical tube 4 via a bearing. Install.

Transmission mechanisms 8, 8a, from the power output shaft 7 of the tractor 1,
The configuration in which power is transmitted to the blade shaft 5 by 8b is the same as that of a known mower.

In the present invention, guide members 9a and 9b for determining the cutting direction of the tall forage C are attached to the reaper having the above-mentioned meaning, for example, in a desired direction for cutting down the tall forage C.
Provided at a height position approximately in the center of the height of the

The root of the feed C pushed to the left or right side in the cutting direction a by the guide 9a or 9b is held by a forked sled 10 directly under the rotary blade 6 so that the cutting action is properly performed.

Further, in order to guide the lower part of the cut feed in the direction of falling down, the direction of rotation of the rotary blade 6 is changed in conjunction with the change of the direction of falling down of the guides 9a and 9b.

Each part of the embodiment shown in the accompanying drawings will be described in detail below.

11 is a vertical shaft that fits into the support tube 12 on the machine frame 3b and is received at the upper end of the support tube by a collar 13; 14 is a horizontal rod provided at the upper end of the vertical shaft 11; the guides 9a and 9b are fixed to the front end of the horizontal rod; The guides 9a and 9b are rods and have a substantially triangular shape in a plane with the stopper as the apex, and the bottom side is attached to the horizontal rod 14.
into the tubes 16a and 16b provided at the rear of the guide 9.
Set the apex angles θ of a and 9b as required and fix with screws 16.

When the conversion lever 17 is provided on the vertical shaft 11 and the cut feed C1 is tilted to the left in the advancing direction, the apex 15 of the guides 9a and 9b is the row row C2 on the right side opposite to the tilting direction of the rows C1 to C1 to be harvested. -C2.

Then, the left guide 9a acts to largely push and tilt the feed to the left as indicated by C1 to CI', and as the feed advances, the inclination of the guide 9a acts to push it down significantly.

If you want to tilt it to the right, use the conversion lever 17 to move the guides 9a, 9
b is rotated toward the feed row C3 to C3 opposite to the above.

Fig. 3 shows a mechanism for securing the above-mentioned converted positions of the conversion lever 17 and guides 9a and 9b, in which a coil spring 19 is hung between the arm 18 fixed to the vertical shaft 11 and the machine frame 3, and the A trouble mechanism is provided for the line X--X connecting the fixing point of the spring and the shaft 11, thereby making the above-mentioned conversion easier and at the same time stably holding it in the conversion position.

In the above example, if the feed C1 is tilted to the left side, FIG. 2 CI',
As can be understood from the position of "CI", the feed is pushed down greatly from the base, but the base has two prongs.
Since it is held between the blades 6 and 6, it can be held approximately upright up to the area where the blade 6 acts.

Therefore, it is in a state where it is easy to cut.

Note that the two-pronged sled 10 has a mounting base 20 at its base as a bracket)
Adjust the cutting height by freely moving up and down at 3C.

21 is its tightening screw.

When the feed C1 is toppled to the left as in the above example, the cut lower part of the feed C1 is flipped to the left by rotating the cutter 6 to the left, thereby making the lodging quick and effective.

Therefore, a rotation conversion mechanism as shown in FIG. 5 is provided between the input shaft 22 from the tractor 1 and the cutter shaft 5, and this is linked to the conversion lever 17, so that the cutter shaft 5 can be rotated counterclockwise when the tractor is turned to the left.
Rotate to the right when tilted to the right.

That is, the driven bevel gear 2 meshing with the bevel gear 23 on the input shaft 22
4.25 is freely attached to the cutter shaft 5 which is perpendicular to the input shaft 22.

The shifter 26 is connected between the bevel gears 24 and 25 by spline or key connection with the blade shaft 5, and engaging clutches 26a and 26b are provided for the bevel gears 24 and 25, respectively, and the shifter fork 28 is attached to the shaft 29, and the above parts are assembled. is assembled into a gear box 30 supported by a machine frame 3.

A lever 31 is attached to the shifter shaft 29 and connected to the arm 18 of the vertical shaft 11 by a link 32.

As mentioned above, when the vertical shaft 11 and the guides 9a and 9b are rotated clockwise in the leftward direction in FIG. 2, the arm 18 and link 32
moves as shown by the solid line in Fig. 3-4, and the shifter lever 31
is rotated to the left in Fig. 4, and the chic 2 is located at the solid line position.
The clutch 26b of No. 6 is engaged with the bevel gear 25, and the rotation of the input shaft 22 is transmitted to the cutter shaft 5 via the bevel gear 23.25 and the shifter 26, causing the cutter 6 to rotate counterclockwise.

Therefore, the upper part of the feed C1 is guided 9a as the reaper moves forward.
It is pushed step by step to the left, and the root is severed.

When turned to the right, each part acts in the opposite direction.

Therefore, the cutter 6 has a double-edged structure in which the blade plates 6C of the double-edged blades 6 a and 6 b are attached to a disc.

If the cut side of the feed C1 falls on or near the rows C1-C1, it will be stepped on by the wheels 1a of the tractor 1, so it is necessary to push it as far away from the rows C1-C1 in the falling direction.

For that purpose, the rear part expands directly above the rotary blade v06.

For example, a guide plate 33 having a parabolic shape or similar to the guides 9a and 9b
Attach it to the machine frame 3a.

Further, a brushing plate 34 is attached to the rotary cutter 6 so as to be rotatable by a certain angle 2α with a shaft 35, and when the above-mentioned tilting is to the left, the brushing plate 34 is automatically tilted at an angle α opposite to the counterclockwise rotation direction of the cutter, and the feed C cut by the blade 6bl is The cut end of the lower end is swept to the left, and the cut end is pushed out of the path of the wheel 1a by the guide plate 33.

Therefore, the present invention automatically and smoothly reaps green fodder such as corn that is taller than the worker from the root and disposes of the cut fodder.
