Description

[Detailed description of the invention] The present invention relates to a bundled waste straw discharging device for a combine harvester equipped with a waste straw binding machine, which allows the bundled waste straw discharged into the field to be placed in an upright position to facilitate drying of the bundled waste straw. be.

The present invention forms a transfer space above the bundling deck and the guide means located in the extension direction of the bundling deck between the bundling passage and the hauling and conveying means tilted upward in the conveying direction, and also provides a transfer space between the bundling deck and the hauling and conveying means that is inclined upward in the conveying direction. The position is located near the perpendicular line from the rear end of the tip trajectory of the discharging arm of the binding machine, and when transporting the bundled waste from the binding space through the transfer space to the haul-up conveyance means, the tip part is pulled up almost linearly on the same plane. It feeds into the straight section of the conveyance means to improve the transfer to the lifting conveyance means, and also increases the transfer distance of the tip in the transfer space, and ties the untied waste straw received by the door of the binding machine with the transfer space. In addition to improving the separation of the base of both bundles of waste straw, the distance from the end of the bundled waste transport means to the field area is increased, and the base of the bundle of bundled waste to be discharged is widened to give a more three-dimensional posture. It is something to do.

Hereinafter, the present invention will be explained in detail based on embodiments shown in the drawings.

A straw binding machine 2 is connected to the rear of the combine harvester 1, and the waste straw from the threshing device is supplied onto a straw deck 3 in an almost horizontal state by a straw conveying chain (not shown) of the combine harvester 1. It is tied almost horizontally. Nodule part 4 of bill holder etc.
The discharge arm 5 is located above the straw deck 3, and the packer 6, needle 7, etc. are located below the straw deck 3. 8 is a transmission case of the bundling machine, 9 is a door, and 10 is a waste straw separation device for distinguishing unbound waste straw from tied waste straw.

A binding passage A is formed between the guide surface 11a of the binding cover 11 of the knot portion 4 and the upper surface of the deck 3.

The front end of the bundled and removed straw hauling and conveying means 12 is located at the rear of the transfer space B that continues to the bundling path A, and the rear end is tilted to a high position so that the rear end is at an appropriate height on the mown field side. A conveyance chain 14 is provided, and is supplied with power from a transmission case 13 connected to the transmission case 8, and a waste filter is attached to a frame 15 by an appropriate method so as to face the conveyance side of the conveyance chain 14. It is connected to the support plate 16. The conveying chain 17 is inclined with respect to the vertical plane so that the conveying side (upper side) of the conveying chain 14 is inward and the non-conveying side (lower side) is outward. A hauling and conveying path is formed between the conveying chain 14 and the straw supporting plate 16, and in order to give rotation to the bundled straw during hauling and conveying, the conveying chain 14 and the straw supporting plate 16 are in a pinched state. is set to a slightly weaker state. A take-in guide body 18 is attached to the tip of the waste straw support plate 16.

A discharge guide body 19 is located in the takeover space B, at a height approximately equal to the guide surface 11a of the knot cover 11 regulating the upper limit of the bundling passage A, and at a position intersecting the latter half of the tip trajectory S of the discharge arm 5. will be established. The discharge guide plate 19 can have any shape such as a strip, a flat plate, or a rod, but its active part is formed by the deck 3.
The leading end is the intake guide 18.
The base portion 19a is fixed to the rear wall 11b of the tubercle cover 11 by bolts. It is convenient to make the mounting hole 20 for bolting a long hole in the vertical direction, because the vertical width of the transfer space B can be adjusted by moving the discharge guide plate 19 up and down in accordance with an increase or decrease in the amount of bundled waste straw.

In the embodiment shown in FIG. 1, the above-mentioned intake guide body 18 has a free end that forms a transfer space B between it and the bundling deck 3, and a base side thereof that forms a transfer space B between the bundling deck 3 and the bundling deck 3. A transfer space B is formed between the guide means (receiving rod) 3a and the guide means (receiving rod) 3a which protrudes substantially in the extending direction. Thus, the transfer space B is vertically regulated by the bundling deck 3 and the receiving rod 3a, the guide surface 11a of the bundling cover 11, the discharge guide body 19, and the intake guide body 18, with the front end being the door 9 and the rear end being the door 9. It is regulated by the starting end straight portion 14a of the conveyance chain 14.

In addition, when transferring the bundled waste straw to the conveyance chain 14, the stock end side rotates greatly using the tip of the bundled waste straw as a fulcrum to be transferred to the conveyance chain 14. On the other hand, it is located on the plant base side and protrudes rearward from the position where the tip portion takes over with the conveyance chain 14 in side view.
The transfer position P of the tip portion to the conveyance chain 14 is the first
It is located in the vicinity of a line hanging from the rear end of the distal end trajectory S of the ejection arm 5, which is indicated by an imaginary line Q in the figure.

A forced stock guide body 21, a stock stock resistance rod 22, and a fall guide plate (shute plate) 23 are fixed to the frame 15, and a wrapping prevention plate 24 and a wrapping prevention rod 25 are attached to the bundled and removed straw hauling and conveying means 12. It is fixed to the transport case 17, and the bundled waste straw is fed into the hoisting and transporting means 12 in an almost horizontal direction, and by the action of the forced stock guide member 21, the orientation gradually changes to a vertical position and is transported to the terminal end, where it is guided to fall. The plant is guided by the board 23 and falls vertically onto the field with the plant base facing downward, and is left in a three-dimensional position. At this time, a stock resistance rod 24 is provided to improve the change to the three-dimensional posture. Set it before it comes into contact with the object. If the position of the stock resistance rod 22 is too early, the posture will return to the original position and the stock will be in front of the stock and will hit the falling guide plate. If it is delayed, the stock will reach the falling guide plate before providing any resistance and the stock resistance rod 22 will not be able to provide enough resistance. Unable to change posture.

The bundled waste straw discharged from the waste straw binding machine 2 by the discharge arm 4 passes through the transfer space B and is transferred to the starting end straight portion 14a of the transfer chain 14 of the waste straw lifting and conveying means 12.
Then, the tip of the tip near the binding position is fed in, and the tip moves almost linearly on the plane along the bundling deck 3, but the stock end rotates significantly and is centered at the inheritance point in plan view. It moves in a fan shape, and the transfer space B is linear and relatively long. The straw is reliably separated from each other at its base (see Figure 3 a, b, c and Figure 4 a, b).

Next, when the bundled waste straw is conveyed by the lifting and conveying means 12, since it is tilted upward, the tip portion goes first (FIGS. 4b and 4c). Therefore, if the bundled straw is perpendicular to the conveyance chain (indicated by Q,
When the waste straw conveying means is horizontally arranged), the waste straw bundles are transported as a bundle, but the heavy stock base is transported later, which creates resistance to the transport of the tips and causes twisting rotation. The bundled waste that causes the action to spread out around the binding string and fall from the end becomes three-dimensional in the shape of a cone as shown in Figure 4d, and since it is lifted from the transfer space, the falling distance is large. Therefore, the base of the stock expands during the fall, and the bundled straw that is released into the field stands upright on the field in a more three-dimensional posture.

As described above, the present invention provides a transfer space above the bundling deck and the guide means located in the extending direction of the bundling deck between the straw tying machine and the linear portion of the bundling and scavenging conveyance means that is inclined upward. , and the transfer position from the transfer space to the hauling and transporting means is located near the line hanging down from the rear end of the discharging arm discharging arm of the straw bundling machine. When conveying the tips of the bundled waste straw (bound part), it is transferred almost linearly on the same plane through the transfer space and fed into the straight line section of the lifting conveyance means, which improves the transfer to the hauling conveyance means. The transfer position was set near the line hanging down from the rear end of the discharging arm's tip trajectory, and the transfer space was lengthened, so the transfer distance of the tip part when transferring the bundled waste straw was increased, and the transfer distance of the tip of the bundled straw was increased, and the For the bundled waste straw and the bundled waste straw in the transfer space, the stock base of both should be well separated, and transport resistance will occur when transporting the tip part due to complete separation of the stock base from the unbound waste straw. In addition, the tip part is held and carried by the hoisting conveyance means, and the stem part is in a hanging position due to its own weight. As the stocks are lifted up and the stock parts are separated, a torsional rotational action is generated on the conveying part, and the stock parts spread out in a conical shape, are transported, and are released in a more three-dimensional posture.

Furthermore, since the bundled waste straw lifting and conveying means is tilted upward in the transport direction, the end of the transport is located above the transfer space, and the falling distance of the bundled waste straw becomes large, causing the spread of the stock base during falling. The effect is greater, and the bundled waste straw that is released into the field and stands upright on the field has a more three-dimensional posture and is more securely placed upright on the field to dry.
This has the effect of facilitating post-treatment of waste such as collection.

In addition, the transfer position of the bundled waste straw to the bundled waste straw hauling and conveying means is set near the line hanging down from the rear end of the dispensing arm's tip trajectory. There is a risk that abnormal force is applied to the conveying means, causing the culms to break or become damaged, resulting in poor conveying posture. In addition, the posture of the bundled waste straw at the time of transfer and transfer is good, and the three-dimensional release effect from the end of the lifting and conveying means can be ensured. Furthermore, if the transfer position is located behind the hanging line (behind the rear end of the movement trajectory of the discharge arm), when the bundled grain culm discharged by the discharge arm is transferred to the lifting conveyance means, Although there is a drawback that the clamping position of the bundled grain culm is unstable, in the present invention, the clamping position can be kept almost constant.

Therefore, the present invention solves the problems when the handover position is on the side of the bundling and discarding straw bundling device and on the lifting and conveying means side,
This has the effect of feeding the bundled waste straw to the lifting conveyance means in an undisturbed posture and at a predetermined clamping position, thereby improving the three-dimensional discharge from the end of the lifting conveyance means.
