Description

[Detailed Description of the Invention] The present invention relates to a bundled waste straw discharging device for leaving bundled waste straw discharged from a waste straw binding machine attached to a combine harvester in an upright position in a field.

When attaching the tying machine to the rear of the combine, it is desirable to perform the tying operation while keeping the transported waste straw discharged from the combine in the same position as possible. It is necessary to release it as close to one side of the machine (the side where the cutting ends) as possible so as not to interfere with the harvesting process.

In addition, with the tying machine, there is a problem in that the tying position is changed depending on the length of the grain culm and the tying is done in accordance with the culm length.

As this type of bundled straw discharge device, there is already a technology that moves and fixes the bundler from side to side depending on the length of the grain culm, and a technology that has a straw discharge device to discharge the bundled straw backwards. I was doing it, but
In order to support the release device at the rear of the binding machine, it was attached by extending it from the support frame of the binding machine or a similar strong member, so the emphasis was placed on providing strong support rather than compatibility with the binding machine.

In view of these problems, the present invention is designed to move the tying machine in the left and right direction to match the attitude of the conveyed straw, and then direct the handover position to the discharge device toward the knotting part side of the tying machine. The position of the waste straw can be kept constant to correspond to the length of the culm, and the discharging device is tilted in front and in plan view to transfer and discharge inherited waste straw.

Hereinafter, a case will be shown in which a transmission cylinder 30, which is a part of the transmission mechanism to the straw discharge device, is used as a support member for the straw discharge device, which is the main part of the present invention.
The present invention will be explained in detail based on the embodiments shown in the drawings. In addition, in the embodiment, in addition to the transmission tube 30, the support frame 33 is also used to fix the transport case 26 of the waste straw discharging device 25 to the transmission case 20 of the waste straw binding machine 1. is supported by the waste straw binding machine 1. In addition, the transmission case 20
The transmission device for transmitting power between the transport case 26 and the transport case 26 includes a first transmission case 28, a second transmission case 29,

However, it is composed of

In FIGS. 1 to 5, the waste straw binding machine 1 is
It consists of a support frame part 3 attached to the rear wall of the combine harvester 2, and a main body part 4 provided on the support frame part 3 so as to be movable in the left and right horizontal directions of the combine harvester 2.

The support frame portion 3 includes a front frame 5 fixed to the rear wall of the combine harvester 2 along the left and right horizontal directions, and a rear frame 6 positioned downwardly and parallel to the front frame 5, and a left and right side frame 7. , 8, and a stay 9 is provided protruding downward and forward from the lower end of the center in the left and right direction of the rear frame 6, and its tip is fixed to the rear wall of the combine 2. A case 10 is attached so that power can be received from the drive device of the combine 2 as appropriate, and a side plate 11 is provided on the outside of the drive case 10.
is installed.

The main body part 4 of the waste straw binding machine 1 connects the waste straw discharge route discharged from the combine harvester 2 and forms a waste straw passage 14 with a stock base deck 12 and a tip deck 13 that are inclined rearward and downward. A door 15 is formed at the end of the waste passageway 14 and can be opened and closed.
A knotting section 16 equipped with a bill holder and a discharge arm 17 are disposed above the terminal end of the straw removal passage 14, and a concentrating section 19 equipped with a needle 18 and a packer is disposed. Part 16, 19
is supported in a cantilevered manner by a transmission case 20 fixed to the tip deck 13 at a certain distance from both parts 16 and 19 in the direction of the mown field (rightward in FIG. 1), and is discharged from the combine 2. Straw waste passage 14
The waste straw supplied to the starting end is transferred on the waste straw passage 14 toward the terminal end by the action of the packer,
The door 15 receives a certain amount of straw, and upon sensing this, the needle 18 and the knotting section 16 are activated to bind the collected straw at a point near the ear tip, and then the door 15 opens and the straw is removed from the straw passage 14. The structure is such that the bundled waste straw is sent out rearward from the terminal end by the action of the discharge arm 17.

This machine part 4 is attached to the combine harvester 2 on the support frame part 3.
Concerning the configuration that is provided to be movable in the left and right horizontal directions, that is, to be movable and fixed along the culm length direction of the conveyed waste straw discharged from the combine harvester 2, and the configuration of the transmission mechanism that transmits power from the combine harvester 2 to the transmission case 20 while allowing this movement. To explain, the stock base deck 12 and the ear tip deck 13 located on the mown field side of the stock base deck 12 are integrally connected at both front and rear ends by sliding bodies 21, 21 having an inverted U-shaped side cross section. Then, tighten both the sliding bodies 21, 21 with the tightening bolts 22, 2 of the front frame 5 and rear frame 6, respectively.
2 so that it can be tightened (see Figure 4), and
A transmission shaft 23 mounted on the drive case 10 in a freely drivable manner extends toward the uncut field side along the left and right horizontal directions of the combine harvester 2, and a spline is formed on the extension part, and a spline is formed in the extension part. The input shaft cylinder 24, which has splines formed on its inner circumferential surface, is rotatably mounted on a shaft, and the input shaft cylinder 24 is spline-fitted to the transmission shaft 23, so that the input shaft cylinder 24 is interlocked and movable in the axial direction (see Fig. 5). ).

Next, the bundled waste straw discharge device 25 is attached to the waste straw binding machine 1 so as to be movable together with the waste straw binding machine 1. That is, this waste discharge device 2
5, a driving sprocket and a driven sprocket (not shown) are rotatably attached to both ends of the conveying case 26, and a conveying chain 27 with a conveying protrusion is wound around both sprockets, and a second transmission case 29 is attached to the back side of the conveying case 26. while fixing the transmission case 20.
A first transmission case 28 is fixed to the side surface, and the first transmission case 28 and the second transmission case 29 are connected by a transmission cylinder 30 having a rotating shaft and a bevel gear therein, and the transmission case 28 is connected to the second transmission case 29 from an appropriate rotation shaft of the transmission case 20. The driving sprocket receives power to rotate the conveying chain 27 in the A direction (FIG. 2), and the pinching body 31 is disposed oppositely along the conveying action surface 27A along one side of the conveying case 26. , disposed on the uncut land side of the conveyance chain 27 are stock guide rods 32 which are sequentially inclined downward with respect to the conveyance chain 27;
The transport case starting end 26a is positioned near the terminal end of the straw passageway 14 so that the bundled waste straw is inherited and held near the tip of the straw, and the transport case terminal end 26b is positioned near the starting end 26a.
It is fixed to the transmission case 20 by the transmission cylinder 30 and the support rod 33 protruding from the rear surface of the transport case starting end 26a.

Reference numeral 34 denotes a drop guide which is attached to the transport case terminal end 26b and has a U-shaped opening toward the transport action surface 27A and forms a guide surface along the vertical direction.

According to this bundled and removed straw discharging device 25, referring to _FIG . 27, and is conveyed along the conveying surface 27A, and during the conveyance, is rotated by the frictional resistance of the clamping rod 31 to spread the base ends into a conical shape, and at the same time, to guide the stock base. The stem side of the plant is gradually lowered by the rod 32, and at the end of the conveyance, it is released from the clamped state, and the drop guide 34 moves the combine 2 into an upright position along the vertical direction as shown in Fig. 1. It falls to the side.

When tying the straw _P2 , which is shorter than the above-mentioned straw _P1 , move the machine section 4 of the waste straw binding machine 1 closer to the uncut field (arrow B in Figure 2) and tie the ears at the binding point. Fix it at a position where the distance from the tip is the same as that for the long straw _P1 (Fig. 3), and perform the tying operation. At this time, the bundled waste straw discharging device 25 is also moved closer to the uncut field (arrow B) while maintaining a constant relationship with the waste straw binding machine ₁ , so that short waste straw is removed as in the case of the long waste straw P1 described above. Even at P ₂ , the area near the binding point can be held and transported.

In other words, the transportation clamping location where the conical spreading of the plant end due to the frictional resistance of the clamping body 31 during transportation can be most efficiently performed is the location near the binding location. By simply adjusting the movement of the waste straw tying machine 1 according to the situation, the location where the waste straw is tied can be kept constant, and the location where the waste straw being bundled and released by the device 25 can be held is always in the vicinity of the binding location. .

Binding of a combine harvester equipped with a straw tying machine, which is equipped with a straw tying machine that can be moved and fixed at the rear of the combine so that it can move and fix the transported waste straw inherited from the combine along the culm direction, and is equipped with a straw discharge device that transfers the bundled waste straw to the rear. In the straw discharging device, the straw discharging device is tilted in front and plan view with respect to the moving direction of the binding machine, with the transfer start end of the bundled straw facing the knotting side of the binding machine. Since it is attached to the transmission case of the binding machine, which is movable and fixed with respect to the input shaft parallel to the direction, through the transmission tube for direct support and transmission, the following effects are obtained.

The transfer position from the bundling position to the waste discharge device does not change and is always transferred to a fixed position.Moreover, it can be transferred to the side of the machine, so regardless of the length of the grain culm, the optimum position is tied and moved. can be released.

Since direct support and transmission is carried out through the transmission cylinder, the transmission part and the support part can be used both, simplifying the structure.

In particular, since the waste straw discharge device is directly supported and transmitted to the transmission case of the bundling device that moves it, the direction of the waste straw conveying device is not restricted even when the bundling machine is moved, and the bundled waste straw is moved toward the machine body. can be transported to the department.
