Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a door regulating device in a binding machine for binding culms such as grain culms or waste straw.

(b) Prior art In a conventional binding machine, when the culm is scraped into the front of the door by the packer, the door is rotated through the culm, and during the return stroke of the packer, the pressing force no longer acts on the door, so the door maintains a constant pressure. It was constructed so that it could be rotated back to a predetermined position by the pressing action of a spring.

(c) Problems to be solved by the invention In the known binding machine, the door rotates back every time the bundler scrapes the culm, so the bundled culm is intermittently and rapidly pushed back. , the converging posture of the culm may be disturbed and the base of the plant may become uneven, and the front and rear bundles may become tangled, and the binding string that is wrapped around the converged culm may move and come off or become loose from the first protrusion. There were cases where bundling errors occurred.

(d) Means for solving the problem The present invention provides a packer on the scraping side of the converging section, and a door on the opposite side, and when the door senses a one-turn clutch, it engages and releases the needle, nodule, and discharge. In a binding machine that operates an arm to release bundles, the door is pressed by a packer through the culm and is provided with a locking device to hold the rotated position, so that the packer scrapes the culm against the collecting part. When the door is rotated in a closed position, the locking member locks the door at the rotated position and prevents the door from rotating back, thereby solving the above-mentioned problem.

(e) Action The culm is intermittently scraped into the convergence section on the front of the door, and at the time of this scraping, the door is rotated via the culm.

At that time, the locking member locks the door, which has rotated by an amount corresponding to the amount of culm that the packer scraped at once, so that it does not return, so the door does not push back the gathered culm, and the culm compresses and expands. is repeated, but the position of the part that comes into contact with the door does not change, which prevents the culm's posture from being disturbed, and also allows the tied string tied to the focused culm to move in the return direction of the police car. There is no.

(F) Example An example of the present invention will be explained with reference to the drawings.
Reference numeral 1 denotes a threshing device mounted on a machine base 2 having a traveling device, and although not shown on the other side, an operation panel, a driver's seat, a grain tank, an engine, etc. are arranged in order from the front. A pre-processing device consisting of a reaping device and a grain culm conveying device is attached to the front so that it can be moved up and down.

Further, a cutter 3 and a binding device 4 are installed in that order at the rear of the threshing device 1, and a straw conveying device 5 is provided at a portion extending over the culm of the threshing device 1 and the cutter 3. The binding device 4 has a bundler 7 and a needle 8 in the lower part of the converging part 6, a knot part 9 and a release arm 10 in the upper part, and a door 11 in the rear part so as to be tiltable back and forth.

Further, the door 11 is attached to the door shaft 13 of the transmission case 12 via an arm 15, and when the packer 7 scrapes the culm and the door shaft 13 rotates together with the door 11, the door link 16 is connected to the door link 16. 1
7 to push down the roller 18 and link 19 in FIG. 2, thereby compressing the constant pressure spring 20.

At this time, the hook 22 at the tip of the bending rod 21, whose one end is pivotally connected to the holding rod 20a of the constant pressure spring 20 and whose middle portion is rotatably supported by the door shaft 13, is pressed and biased by the return spring. Locking claw 23
is engaged to hold the one-turn clutch in the disengaged state.

A tooth receiving body 27 having a plurality of downwardly inclined teeth 25 and a high receiving portion 28 at the end thereof is attached to the rear inner surface of the transmission case 12, and the door link 18 is erected by a winding spring 30. The pushed ratchet pawl 28 is pivotally supported by a pin 31.

In the above-mentioned binding device 4, the packer 7 operates intermittently to scrape the culms into the binding part 6 in front of the door 11.
As the amount of convergence increases, Patsucar 7
When the latching operation is performed, the ratchet pawl 28 is rotated from the A position to the rearward B position as shown in FIG. 3, and the ratchet pawl 28 is pushed down together with the door link 16 from the state shown in FIG.

At that time, if the packer 7 scrapes 5 to 6 times to reach a predetermined amount of convergence, although this varies depending on the amount of culms scraped at one time or the size of the bundle, in this embodiment, the packer 7 scrapes 2 to 3 times. The door 11 rotates to the ``R'' position, and the ratchet pawl 28 passes over the uppermost tooth 25 and is locked, so the door 11 does not return to the ``I'' position as in the conventional case, but is When it is pulled in, it returns very slightly, but when it is scraped in for the third time, the ratchet pawl 28 passes over the second tooth 25 and is locked.
Even when the door 11 is subsequently scratched, the door 11 does not return from the position C to the position A in FIG. rotates, the one-turn clutch engages, the cam 32 rotates, the needle 8, the knot 9 and the discharge arm 10 operate to discharge the bundle as shown in FIG. When the tooth body 27 rides on the high receiving part 26 and from this state the cam 32 rotates slightly and the roller 18 is pushed up by the slope of the cam 32, the ratchet pawl 28 comes off the receiving part 26 and the winding spring 30 The door link 16 quickly returns and rotates, and the door link 16 further rises, returning to the state shown in FIG.

The return position of the ratchet pawl 28 is regulated by an appropriate stopper.

In the above-mentioned bundling device 4, the grain culm harvested and transported by the pre-processing device is threshed by the threshing device 1, and waste straw discharged from the culm discharge port is sent later by the waste straw conveying device 5.

When the waste straw is shredded, cutter 3 is used.
When the top shutter is opened, the waste straw is shredded.

Furthermore, when the waste straw is bundled and discharged, when the shutter is closed, the waste straw passes over the cutter 3, the scraping tines 32a... scrape it backwards, and the packer 7 scrapes it into the collecting section 6. .

At that time, when the door 11 is tilted to the B position as described above via the culm focused by the pack car 7,
Since the ratchet pawl 28 is locked by the upper teeth 25, the door 11 does not return to the A position even if the holder 7 returns and rotates, and the culm compressed by the return of the holder 7 expands. The culm in the vicinity of remains stationary, therefore, although the binding string 33 is pulled out by the tilting of the door 11, it is not pushed back by the door 11, and the binding string 33 is pulled out from the first protrusion 3.
5, the binding string 33 will not come loose and the building 9a will make a mistake in scooping up the string, and the binding string 33 will not come loose between the building 9a and the holder 9b.

As the convergence progresses, the ratchet pawl 28 is further engaged with the lower tooth 25, and when the convergence amount reaches a predetermined amount and the discharge arm 10 discharges the bundle, the ratchet pawl 28 is moved to the receiving portion as shown in FIG. 26, and immediately after that, the ratchet claw wraps around spring 3.
0, it rotates back and rises to return to the state shown in FIG.

Further, the released straw bundles are thrown by the tine release body 36 towards the already mown field diagonally rearward.

Figures 7 and 8 show other examples of a bundle conveyance device, and this bundle conveyance device 36a has a conveyance chain 37 whose terminal end is higher than its start end and which is installed obliquely toward the mown field, and whose upper surface is The frame body 39 of the conveyance chain 37 is attached to a transmission cylinder 40 protruding diagonally rearward from the transmission case 12 via arms 41, 41 and a mounting plate 42. The clamping rod 38 is attached to the transmission cylinder 40 by an inverted U-shaped rod 43, and the inverted U-shaped rod 43 is connected to the holding frame of the binding device 4 by a connecting rod 45.

The straw bundles released from the bundling device 4 have different release postures depending on their size, culm length, dryness, etc.

For example, heavy bundles and long culms become entangled and are discharged diagonally downward, while short culms and light bundles are discharged almost immediately after, making it uncertain whether they will be handed over to the bundle conveying device 36a. Attach the frame 39 to the mounting plate 4
The holding frame 38a of the clamping rod 38 is inserted through the long hole 48 bored in the seat plate of the inverted U-shaped rod 43. The bolts 49 are screwed together, so when transporting short culms or dry, light bundles, the starting ends of the transport chain 37 and clamping rod 38 are raised and screwed, and long culms are used to transport heavy bundles. In this case, by lowering the starting end of the culm and screwing it on, it is possible to carry out reliable transfer regardless of the length or weight of the culm, and to improve the three-dimensional release performance from the end of the culm to the field.

(g) Effects of the invention As described above, the present invention provides the packer 7 on the scraping side of the converging section 6, and the door 11 on the opposite side, and the one-turn clutch is engaged by the sensing operation of the door 11, and the needle 8 and In the tying machine which operates the knotting part 9 and the discharging arm 10 to bind and discharge, a locking device is provided to hold the door 11 in the rotated position when it is pressed by the packer 7 through the culm. When the police car 7 tilts the door 11 by scraping the culm, and then returns, the door 1
1 does not return and turn, so the focused culm does not move back and forth within the focusing part 6 and disturb its posture, and the binding string 33 is loosened and released from the first protrusion 35. There is no possibility of the cord coming off, the building 9a does not scoop the cord, and there is no possibility of tying mistakes.
