Description

[Detailed Description of the Invention] The present invention relates to a harvester for a tractor, and an object of the present invention is to enable a harvester with a chute to be transported while the chute is folded and attached to the harvester.

Some tractors have a chute-equipped harvester, such as a forage harvester or a maize harvester, attached to the front or rear part of the tractor via a link mechanism so as to be able to move up and down.

In conventional harvesters of this kind, the chute protrudes upward and is high, so it cannot be transported as is, and therefore, when transporting the harvester, the chute must be removed from the harvester body.

According to this conventional example, since the chute is relatively heavy and bulky, it is very troublesome to attach and detach it each time.

Therefore, the present invention allows the chute of the harvester to be transported in a folded state without having to remove it from the main body, and for this reason, in the present invention, the chute is attached to the harvester attached to the tractor. In the chute, the chute can be bent up and down via a bending section near the harvester main body, and can be rotated around a vertical axis via an operating rod at a lower part of the bending section. , the operating rod is provided with a support for supporting the folded chute.

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

A three-point linkage mechanism 3 connects the harvester 2 to the tractor 1.
In FIGS. 1 and 2, which show a side view and a plan view of the overall structure of the tractor 1 mounted (connected) so as to be able to rise and fall freely through the
It is wheel-shaped, and a bottomed container 7 capable of dumping is detachably attached to the bonnet 6 thereof.

Further, the tractor 1 is equipped with a control handle 8 and a seat 9 that can be freely changed between forward driving and backward driving.
In this embodiment, the harvester 2 is attached via a three-point linkage mechanism 3 for backward operation.

The harvester 2 includes a pair of left and right dividers 10, a cutting section 11, a shred discharge section 12, and a chute 13.
In this example, the crop P to be used as feed can be cut down at the cutting part 11 at the root thereof, shredded by the shredded discharge part 12, and then discharged into the container 7 via the chute 13. Illustrated.

The chute 13 is a harvester main body 1 including a housing 15 of a flywheel 14 as shown in FIG.
At one side of the upper part of 6, it can be bent up and down as shown by the chain line in FIG. , 18 is its rotating portion, which is constructed by fitting the base of the chute 13 into a fixed cylinder 19 on the side of the harvester main body 16 so as to be rotatable.

At the base 13A of the chute 13 is a rotating operation rod 2.
0 is pivoted 21, and the operating rod 20 extends toward the rear wheel fender 22 of the tractor 1, and is detachable from a metal fitting 23 attached to the upper surface of the fender 22.

Therefore, by removing the operating rod 20 from the metal fitting 23 and pushing or pulling it or swinging it from side to side, the chute 13 can be freely rotated around the vertical axis from the seat 9 side, and the deflector 24 at the tip of the chute 13 can be moved toward the container 7. It is said that the direction can be changed freely.

As shown in FIG. 3, a pin 17A corresponding to the bent portion 17 can be inserted and removed, and the chute 13 can be folded around the bent portion 17 by removing the pin 17A.

A receiver 25 for receiving the chute 13 folded around the bent portion 17 is attached to the operating rod 20.

As shown in FIG. 5, the receiver 25 may have a U-shape that expands upward and is fixed on the operating rod 20, but as shown in FIG. Stay 2 that can be slid and fixed
It can also be attached via 7.

In addition, in FIGS. 1 and 2, 28 is a guard, which is provided on one side of the tractor 1 in the longitudinal direction via a stay 29. As shown in the figure, a support 30 is attached, and in cooperation with the support 25, the folded elongated chute 13 can be supported at a plurality of locations.

In this example, a pair of left and right gauge devices 31 are attached to the harvester 2, and the gauge devices 31 are attached to the upper end of a gauge wheel support 33 on a bracket 32 fixed to both sides of the front lower part of the harvester main body 16, as shown in FIG. Attach the part with pin 34 so that it can move up and down,
Pin insertion holes 35 and 36 are formed in the bracket 32 with different phases on a large and small circular arc surface centered on the pin 34, and the two pin holes opened in the gauge wheel support 33 and the pin insertion holes 35 and 36 are formed in different phases. The height of the gauge wheel 38 can be adjusted to be large or small by allowing the pin 37 to be freely inserted or removed while either of the two is aligned.

In this example, the divider 10 is provided with a feed mechanism 39 that feeds the root part of the crop to the cutting section 11, and the feed mechanism 39 consists of a sprocket wheel 40 and a belt 42 with claws 41 endlessly wound around it. At this time, sprocket wheel 4
0, the upper and lower pair of the plate-shaped stay 43 is the divider 1
0, are connected via a connecting plate 44, and are configured to support a wheel shaft 45 rotatably around a vertical axis (see FIG. 7), and in this case,
The space between the wheels 40 is made into a space to prevent dirt, grass, etc. from getting on top of it, as in the case where the space between the wheels 40 was conventionally closed with a plate.

The cutting section 11 is composed of a pair of left and right rotary cutters 46 that rotate about a vertical axis. In this example, each cutter 46 is provided with a feed roller 47 as a coaxial center, and is interlocked with the feed mechanism 39.

The shredded discharge unit 12 has cutters 48 arranged radially on the front surface of a flywheel 14 which is rotated about an axis 52 in the front and back direction of the housing 15, and discharge fins 49 protruding from the outer periphery at predetermined intervals in the circumferential direction, as shown in FIG. In addition, a fixed cutter 51 is attached to one side of a window 50 formed in the housing 15 at the rear part between the feed rollers 47.
1 and the rotary cutter 48 are configured to send the shredded crop to the chute 13 via a discharge fin 49.

In addition, the flywheel 14 of the shredded discharge part 12,
The rotary cutter 46 of the cutting section 11, the feed mechanism 39, etc. are connected to the PTO of the tractor shown in FIGS. 1 and 2.
Power from the shaft is transmitted to the winding transmission mechanism 54 via the universal joint shaft 53 and driven.

Further, although not shown, the deflector 24 can be made up and down by wires, cables, etc. provided along the chute 13, and the wires, etc. can be operated from the seat 9.

Therefore, in the above-mentioned embodiment, the crop P is drawn in by the feed mechanism 39, and the crop P is pulled in by the cutting section 11.
When the cut is made by the feed roller 47, it is cut into pieces by the window 50, and is shredded by the shredding discharge section 12 consisting of the fixed cutter 51 and the rotating cutter 48, and then by the third discharge fin 49. The air is blown into the chute 13 as shown by the arrow in the figure, and the chute 1
In order to store feed evenly in the container 7, the rotating part 1
The chute 13 is rotated around the vertical axis 8 by pushing and pulling the operating rod 20 or by swinging it left and right.

By the way, since the chute 13 is at a higher position than the container 7 at the end of harvest or when traveling to the field, the pin 17A is removed and the chute 13 is folded using the bent part 17 as a fulcrum, and the folded chute 13 is moved to the operating lever. Receiver 25 and guard 2 provided in 20
It is supported by a support 30 provided on the 8th side and is operated (transported) in this low state.

The present invention is a harvester 2 with a chute 13, and since the chute 13 is rotatable around the vertical axis by the operating rod 20, the tip of the chute 13 can be changed to the left or right. When the container 7 is provided, crops can be accurately discharged to a container car that is being followed by the tractor 1.

Further, the chute 13 has a bent portion 17 on its base side.
It can be folded up and down around the center, and can be operated in a low-bulk position.The folded state can be supported by a receiver 25 attached to the operating rod 20, thereby ensuring operation in a stable position.
