Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention is a harvester that bundles several threshed straw bundles discharged from the outlet of a threshing device into a large bundle by a binding device provided on the outside. The present invention relates to a knotter door device.

(B) Conventional technology Conventionally, a door arm fixed to a door shaft as a door device of a harvester notter that bundles several threshed straw bundles discharged from the outlet of a threshing device into a large bundle by a binding device provided outside It has already been known from Japanese Utility Model Application Laid-Open No. 61-178834 that the door is attached to the outer end of the door arm so as to be bundled into a large bundle in order to increase the number of bundles.

(C) Problems to be solved by the invention In the known harvester notta door device, when the packer scrapes the straw bundle into the focusing portion and compresses the bundle during focusing, the door device extends downward from the door shaft to the door arm. Since the pressure acts on the door, the load for cutting the door becomes unstable, the bundle alignment becomes poor, and when the bundle becomes small, the tightness of the bundle also becomes poor. Also, in order to rotate the door shaft by the angle required to operate the one-rotation clutch, the door attached to the end of the long door arm must be greatly lowered and rotated by the compression force of the packer, causing bundle leakage. To do. If the turning angle of the door arm is reduced in order to solve such a problem, there arises a problem that the engagement / disengagement action of the one-turn clutch becomes uncertain.

(D) Means for Solving the Problems The present invention is directed to a discharge arm provided on one side of the focusing section 27 for a straw bundle that has been threshed by the threshing device 1 and discharged from the outlet.
In the harvester notter configured to bind and discharge several bundles by the binding device 6 including the knot 23 surrounded by the knot 24 and the knot guide 26, the packer 18 provided on the other side, the needle 20 and the door 21. A floating shaft 38 is provided at a position spaced apart from the shaft 30 in the bundle discharging direction, and the door 21 facing the outside of the knot guide 26 is attached to the floating shaft 38 at an inner end of a door arm 37 attached to an outer end thereof. Part, and the door arm
37 and the door shaft 30 are interlockingly linked by a link 41 along the bundle discharge direction so that the door shaft 30 rotates when the door 21 senses and operates, and the above-mentioned problem is caused by forming the focusing portion 27 above the link 41. I solved the point.

(E) Action The straw bundle that has been threshed by the threshing device 1 and discharged from the culm is supplied to the binding device 6, and the packer 18 of the binding device 6 causes the straw bundle to move to the outside door 21 and Lower guide plate
Focusing section 2 formed by 25a, 25b, link 41, upper knot guide 26 and receiving plate 26a extending outward from it.
Scratch to 7.

While performing such a focusing operation, even if the door 21 is arranged at a position outside the door shaft 30 and largely separated in the bundle discharging direction in order to collect a large number of bundles by enlarging the focusing portion 27, Since the door arm 37 is short because the door arm 37 and the door shaft 30 are interlockingly connected through the link 41, the moment is extremely small even when downward pressure is applied to the door arm 37, and the vertical movement amount of the door 21 A large pivot angle of the door arm 37, which is linked via the link 41 to the door shaft 30.
When the amount of focusing reaches a predetermined amount, the one-rotation clutch is surely engaged and each part of the binding device 6 is bound.

(F) Embodiment An embodiment of the present invention will be described with reference to the drawings, in which 1 is a threshing device mounted on a machine base 3 having a traveling device 2,
A thresher stand 5 is provided on the side of the supply port, and a binding device 6 is attached to the outside of the culm so that it can be moved back and forth while being supported by rails 7, 7, and the engine at the rear of the thresher 1 An engine for driving the threshing device 1, the traveling device 2, and the bundling device 6 is housed in the cover 8, and various operation levers 11 ... Are arranged on the operation panel 10 provided at the rear part thereof, and the handle 12 is attached, A pair of front and rear bag hooks 13 and 13 are projected on the binding device side of the operation panel 10 and the handle 12, and a pair of left and right bag hooks 15 and 15 are projected on the rear surface of the operation panel 10. Kakeru 13,15
A bag support 16 fixed to the machine base 3 is provided below.

The binding device 6 has a transmission case 17 and a packer 18 at the bottom.
, A needle 20, and a door 21, and a knot 23 and a discharge arm 24, which are driven by a transmission device 22 that bypasses the ear case side from the transmission case 17, are provided above the outer door.
Surrounded by 21, a lower stocker side and ear side guide plates 25a, 25b, a knot guide 26 of an upper knot 23 and a receiving plate 26a extending outward from the knot guide 26, and a link 41 described later. The space is a focusing unit 27.

Further, the protruding portion 29 provided on the base portion of the arm portion 28 of the needle 20 is rotatably supported by the door shaft 30, and is placed in the focusing portion 27 in the standby posture as shown in FIGS. 1 and 3. The crank pin 33 at the tip of the crank arm 32, which projects and is projected on the timing shaft 31 provided with the one-rotation clutch,
Since it is interlockingly connected to the vicinity of the protruding portion 29 of the arm portion 28 via the link 35, when the timing shaft 31 makes one rotation, the needle
20 rotates back and forth within a predetermined range.

The door 21 is arranged outside the door shaft 30 at a position largely separated in the bundle discharge direction, and the door arm 37 of the door 21 is fixed to a floating shaft 38 rotatably supported by the transmission case 17. And a link arm 39 protruding from the floating shaft 38.
Is interlockingly connected to a link arm 40 projecting from the door shaft 30 by a link 41 extending in the bundle discharge direction. The link 41 slants an outer portion of the door shaft 30 downwardly and obliquely downward, and lowers the lower portion. As shown in FIG. 1, it is made to project substantially horizontally to the vicinity of the door 21. When the condensed bundle of straws is compressed, the link 41 supports the bundle of straws, so that downward pressure is not applied to the door arm 37, and a predetermined door breaking load can be obtained.

Further, the outer portions of the guide plates 25a, 25b are bent obliquely downward and outward at a position slightly lower than the inclined portion of the link 41,
It is hung vertically before the guide shaft 38 and from substantially the same height, and a root aligning plate 42 is erected on the rear side of the guide plate 25a on the stock side. Then, the outer side of the root aligning plate 42 is connected to the guide plate 25a.
Of the guide plate as shown in FIG.
25a is substantially parallel in a side view and is bent forward to form a stock receiving plate 43 at a position lower than an extending portion 41a of the link 41 which is a supporting portion near the door 21 and a hanging portion of the guide plate 25a. 25a ′
It is fixed to. In the above-mentioned harvester knotter, the straw bundles that have been threshed and discharged from the culm outlet of the threshing device 1 are scraped by the packer 18 into the focusing portion 27, and the midway portion of the culm length is supported by the link 41 and the door 21. The root portion of the stock is guided by the root aligning plate 42 and falls from the outer inclined portion of the guide plate 25a onto the stock receiving plate 43 to be received.

At this time, since the needle 20 is in the standby position, the protruding portion 29 of the arm portion 28 enters the focusing portion 27 and a gap of about one bundle is formed between the end portion and the knot guide 26. Therefore, the straw bundle pressed under pressure by the packer 18 does not become extremely flat, and the scratched straw bundle does not return, and the outside of the straw bundle is widened to the converging part that is widened in sequence. It shifts and is focused. At that time, the bundled straw bundle is supported by the link 41 in the vicinity of the door 21 and does not press the door arm 37, and the stock base is low stock plate as described above.
Since it falls on 43, it is pressed against the lower part of the already bundled straw bundle on the link 41, and the front straw bundle is sequentially moved toward the door 21, and on the front surface of the door 21. The back straw bundle pushes up the front straw bundle, and this straw bundle moves in the opposite direction on the straw bundle moving outward on the extension part 41a, and eventually the straw bundle is moved up and down. It can be focused into an elliptical shape with two steps.

When the door 21 is sensed and operated, the door 21, the door arm 37, the floating shaft 38, and the link arm 39 rotate integrally, so that the link arm 40 of the door shaft 30 is moved by the link arm 39 via the link 41. When the needle 20 is pulled outward and rotated, a one-turn clutch is engaged, the needle 20 is hooked as shown by a chain line in FIG. 1, and the projecting portion 29 retreats downward from the focusing portion 27. The straw bundle pushed by the arm portion 28 is pushed into the focusing portion in a state where the projecting portion 29 is withdrawn, and the bundle is tightened and tied up by the string lacing by the bill, and the discharging arm 24 discharges it sideways.

(G) Effect of the Invention The present invention has the following effects due to the above-mentioned configuration.

(I) The door arm 37 having the door 21 attached thereto is mounted on the floating shaft 38 provided at a position separated from the door shaft 30 in the outer bundle discharging direction, and the door arm 37 and the door shaft 30 are linked and linked by the link 41. By forming the converging part 27 above the converging part 27, the converging part 27 can be formed large, so that a large number of straw bundles can be formed.
Can be bundled and bundled.

(Ii) Moreover, although the door 21 is largely separated from the door shaft 30 to the outside, since the door arm 37 and the door shaft 30 are linked and linked by the link 41, the door arm 37 can be formed short. Unlike the one with a door arm that extends long outward from the door axis of, the downward pressure does not act on the long door arm and the door cutting load does not become unstable. The one-turn clutch can be engaged and disengaged by accurately sensing and operating 21.

(Iii) Further, even if the door arm 37 is rotated at a large angle to ensure the engagement / disengagement action of the one-rotation clutch, the door may be largely rotated downward as in the conventional case, causing bundle leakage. There is no.
