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).

When the above-mentioned reaping machine is configured by using an agricultural tractor and attaching the reaping mechanism section to it as an attachment, the height of the feed is the height of the operator or higher, so it is difficult to lodge the feed with the roots cut off. Post-processing is very troublesome.

The present applicant has previously proposed a device aimed at smoothing the subsequent processing and improving cutting efficiency (see Utility Model Application No. 119159/1983 (Japanese Utility Model Publication No. 33852/1983)).

The purpose of the present invention is to improve the feeding mechanism in the falling direction and the dispensing stopper for the cut root in the previous invention to ensure smooth and reliable cutting and laying down.

The invention of the prior application has a guide 3L that pushes approximately the center of the tall feed C in the cutting direction on the machine frame 2 attached to the agricultural tractor 1.
, 3R is provided, its guide is supported by the vertical shaft 4, and the cutting direction is changed to the left or right of the advancing direction by rotation of the shaft, and the reaper input shaft 5 and the blade shaft 7 are set in the rotating direction. The conversion mechanism 8 and the guide 3L are interlocked via a conversion mechanism 8.
, 3R is interlocked with the folding direction change mechanism to rotate the cutter 9 in a direction that guides the cut root side of the feed in the folding direction, and a two-pronged sled 10 is provided below the rotary cutter 9 to hold the root of the feed. This is a tall forage cutter installed.

In the above-mentioned reaper, the cutting down direction is guided by a feed belt 3 having a substantially triangular planar shape with the front end on the advancing side as the apex, and the maximum pushing position of the feed belt 3 is approximately the same as the cutting position of the rotary blade 9. - It is in a vertical plane, and is provided with a member 11 that controls the amount of feed fed out from the cutting base side.

1. In Fig. 3, move forward in the direction of arrow a with the center of movement X--X aligned with row C of the feed to be harvested.

In the case shown by the solid line, the feed belt 3 is rotated in the direction of the arrow, and the reaping blade 9 is also rotated in the same left direction.

As it progresses, the middle of the height of the feed C to be harvested is pushed by the feed belt 3, and is gradually pushed in the direction of falling to the left of the progress.

The root of the feed C1 is guided by the two-pronged sled 10Vc and guided toward the cutter 9, and when it reaches the cutting position, it is located at the maximum pushing position of the belt 3 (the position of the pulley 25) as shown in C2 and is greatly tilted. The root was cut off in this state.

In this case, the bell) 3 is provided with an engaging protrusion 31 or has a roughened surface that has a large friction against the feed.

A plurality of double-sided cutting blades 9b are provided at approximately equal intervals on the circumferential surface of the rotary blade 9//i disc 9a, and sweeping plates 9d are rotatably provided on both sides in each direction.

Therefore, the root of the cut feed is paid out by the above-mentioned blowing plate 9d at a position where it cannot be stepped on by the tractor wheels, but in this case, if the feed amount is too large, it will be bent by the belt 3 in the direction of falling down. The feed that has been left will stand.

Therefore, the root stopper 11 is provided to stop the ejected root and prevent excessive ejection.

The stopper 11 is shown as an example attached to the tip of the sled 10, but
It may be supported by the main machine frame.

When tilting to the right in the direction of travel, the guides 3R, 3L and the feed belt 3 are placed at the position indicated by the chain line in FIG. 3, the belt 3 is rotated clockwise in the direction of arrow d, and the cutter 9 is also rotated clockwise.

An example of the overall configuration of the embodiment shown in the drawings will be described below.

It is provided with a cylindrical pipe 2a and a connecting member 2c integrally with a machine frame 2 attached via an agricultural tractor IK pitch box 1a etc.
The rotational direction conversion gear box 8a is attached to the connecting member 2c.

A knife shaft 7 is arranged below the gear box 8a, and a knife plate 9a is attached to the lower end.

As shown in Figure 2, the input shaft 6K is installed next to the gear box 8aK.
) Transmitted from the output shaft 1b of the tractor 1 by a transmission mechanism such as a belt or chain.

The bevel gear 12 is fixed to the input shaft 6 within the gear ring 8a, and the bevel gears 13, 14 meshing therewith are loosely fitted to the cutter shaft 7.

The clutch 15 connected by the cutter shaft 7t/I spline or slide key is shifted, and the rotation direction of the cutter 9 is changed by engaging the gear 13 or 14 by 16 or by positioning it in the middle.
or stop it.

The guide support vertical tube shaft 4 is fitted into the fixed cylindrical tube 2a, and the guide support frame 17 is fixed to the upwardly extending tube portion 4a as shown in FIG. Install.

Approximately triangular guides 3R and 3L are attached to the bracket 19 with shaft pins 20 and bolts 21.

The drive pulley 22 is attached by extending the cutter shaft 7 directly or using the connecting shafts 7 a and 7 b directly below the guides 3R and 3L, and pulleys 23 to 25 are provided at the three vertices of the guides 3R and 3L.
The above-mentioned feed belt 3 is suspended between the guides 3R and 3L with at least its protrusion 3a extending outward from the guides 3R and 3L.

Therefore, the cutter 9 and the feed belt 3 rotate simultaneously in the same direction.

Between the booths IJ23, 24, 24, and 25, as shown in FIG. 4, belt receivers 26 are provided on the guides 3R, 3L to receive the reaction force of the feed.

However, in FIG. 2, the belt support 26 is omitted.

The cylinder shaft 4 is rotated by the conversion lever 27 fixed to the guide support frame 17.
is rotated to switch the guides 3R, 3L and the feed belt 3 to the positions shown by the solid lines and chain lines in FIG.

FIG. 5 shows the conversion positioning mechanism shown in the direction V in FIG. A trapezoidal stopper 31 loosely fitted onto the provided pin 30 is pushed by the spring 32 and latches into the lock hole 28b.

When the switch is operated with the lever 27, the stopper 31Vi spring 31
It comes off from the lock hole 28b against the other lock hole 28b.
Multiply b.

The lock holes 28b at both ends of the elongated hole 28a are arranged at the switching angle position of the feed belt 3.

The other protruding piece 33 of the cylindrical shaft 4 is interlocked with a lever shaft 37 vertically supported by the connecting member 2c through a long hole 34, a pin 35, and a lever 36.

Link 39 to the other lever 38 fixed to the lever shaft 37
, is interlocked with the shaft of the clutch shifter 16 in the gear box 8a through the lever 40, and changes the feed belt 3 and rotates the belt 3.
and rotational conversion of the cutter 9 are simultaneously performed by the lever 27.

Guides 3R, 3L, feed belt 3 (fi, as shown in Figure 1, loosen the bolts 21 and remove guides 3R, 3L, feed belt 3
is tilted up and down around the shaft pin 20 within the range of the elongated hole 43, and the operating height position of the belt 3 is adjusted according to the height of the feed tilted by the wind or the height of the cut feed. .

In this case, even if the feed belt 3 is tilted with respect to the drive pulley 22, as is clear from FIG. 3, the winding angle is very small, so there is no problem with the drive.

1 and 2, reference numeral 41 designates a cylinder 42/l'i of the cutter shaft 7 and its extended shaft 7b, which also serves as a cylinder to prevent feed leaves from wrapping around the shaft 7b.
