Japanese Utility Model Publication 54-177342

  The proposed waste straw bundling device has a connecting frame at the bottom, so that it is possible to keep the storage case from being loaded even if it is removed from the threshing device and lowered to the ground. Since the pipe material or the like is formed into a frame having a straight grounding portion having a sufficient length in the front-rear direction and the left-right direction by bending the pipe member in a plane, the waste wall binding device is provided in a place with unevenness. When you drop down, it may climb up the ridge on the ground and become unstable. Further, the waste wall binding device is a horizontally long structure, and the frame having the above configuration is longer in the left and right direction than the length in the front-rear direction. It was necessary to lower it to a flat place that was long in the left-right direction. In particular, when performing maintenance on the waste straw binding device itself, it is necessary to sufficiently consider the place and direction of lowering so that the waste straw binding device does not wobble during the maintenance.

  In addition, since the frame is deployed at the bottom, when the removed waste straw bundling device is lowered directly to the field or open field, soil and mud adhere to the connection to the threshing device at the front end of the frame, and when connecting In some cases, it was necessary to carry out soil removal processing.

  The present invention has been made paying attention to such points, and can remove the waste straw binding apparatus at any place and place it stably, and thresh the removed waste straw binding apparatus. The main purpose is to enable quick connection to the device.

Storage case first invention, that the Tomo When the exhaust straw bundling apparatus above the support frame that is detachably coupled to the rear of the threshing apparatus connecting supports, houses the binding winding cord supplied to the exhaust straw tie and wherein in a state does not protrude to the left and right lateral outer and rear sides of the support frame, and deployed with its case bottom is located below the lower end of the supporting frame, before SL from the support frame of the pair The stand is protruded downward, and the pair of left and right stands are each made of a pipe material having a horizontal straight lower pipe portion, and the drainage frame is removed from the rear portion of the threshing device. The lower pipe portion of the pair of left and right stands is stored in the storage so that the straw binding device, the support frame, and the storage case are supported by the pair of left and right stands. Characterized in that than the bottom of the case over the scan are protruded downward.

  According to the above configuration, when the waste straw binding device is removed from the threshing device and lowered to the ground, the left and right stands are independently grounded with a large interval, and thus can be stably lowered even in a place that is long and flat in the left-right direction. In addition, the left and right stands protrude downward from the support frame so as to protect the storage case for the binding winding string that is provided below the draining cord binding device. In this case, even if soil or mud adheres to the lower end grounding part of the stand, it does not adhere to the support frame, and it is necessary to perform soil removal at the connection point when connecting the draining unit binding device to the threshing device again. Absent.

  Therefore, according to the first invention, the waste straw binding device can be lowered and placed stably at an arbitrary place, and the removed waste straw binding device can be quickly connected to the threshing device. Became.

According to a second invention, in the first invention,
The rear pipe portion of the pair of left and right stands is connected to the rear end portion of the support frame in a state of being positioned on the rear side of the rear plate of the storage case .

According to a third invention, in the first or second invention,
A case support portion for locking the storage case so that it can be inserted and removed from the rear side of the apparatus is fixed to the support frame side.

According to the above configuration, in a state where the exhaust straw tie is coupled to the rear of the threshing apparatus can be easily performed by inserting and removing the storage case from the rear exchange 換等 unity winding string.

According to a fourth invention, in any one of the first to third inventions,
A string feeding hole is provided in the rear plate of the storage case, and a string brake that acts on the binding string led out from the string feeding hole is provided on the outer surface of the rear plate.

  According to the above configuration, in a state where the waste straw binding device is connected to the rear part of the threshing device, a predetermined supply passage is provided by operating the binding cord fed from the binding winding cord through the string brake by operating from a wide working space behind the device. Can be supplied and loaded into the waste straw binding device.

  FIG. 1 shows a side surface of the rear part of the self-removing combine, FIG. 2 shows a plane thereof, and FIG. 3 shows a side surface of the waste straw processing unit. A disc-shaped waste straw cutter C is connected to the rear end of the threshing device 1 mounted on the rear part of the machine body, and a waste straw binding device B is arranged behind the waste straw cutter C, with the rear fulcrum a as the center. By lowering the flow path switching plate 2 arranged so as to be swingable up and down and closing the upper entrance of the waste straw cutter C, the waste straw in the fall-down posture carried out from the threshing device 1 and transported by the waste straw transport device 3 Can be supplied to the waste wall binding device B, and the flow path switching plate 2 can be raised to open the upper inlet of the waste wall cutter C, so that the discharged waste wall that has been conveyed can be shredded and released downward. It is like that.

The exhaust straw binding device B, a waste straw that has been supplied by the lateral falling posture by a predetermined amount at a time collected united, the formed straw bundles is intended to release the machine body backward, it is deployed in the exhaust straw tip side A converging space S is formed at the upper and lower intermediate portions of the transmission case 4. In addition, as shown in FIG. 2, on the stock base side of the waste straw binding device B, a stock stocking apparatus D is provided that strikes and aligns the stock end of the waste straw that is carried in by a striking plate 5 that swings left and right. .

  In the lower part of the transmission case 4 on the lower side of the converging space S, a crank-type scraper packer 6 for feeding the conveyed waste straw toward the converging space S, a needle 7 for supplying a binding string, and a converging space S A sensing door 8 for detecting the collected pressure of the collected waste straw is provided, and the upper part of the transmission case, which is the upper side of the convergence space S, is driven into the working area of the packer 6. A crank-type auxiliary packer 9 for feeding, a string guide plate 12 facing the converging space S, a known knotting mechanism 10 of a knotter bill type, and a crank-type discharge mechanism 11 are provided. Are always driven, and the lower needle 7, the upper knot mechanism 10, and the discharge mechanism 11 are intermittently driven based on sensing of the focusing pressure.

  The basic bundling operation of the waste straw bundling apparatus B will be described below. In other words, the waste straw that has been conveyed is first scraped back by the auxiliary packer 9 and subsequently sent into the converging space S under the scraping action of the scraping packer 6. While the focusing pressure acting on the sensing door 8 is less than the set value, the one-turn clutch (not shown) inside the case is disengaged, and the needle 7 stops at the standby position retracted below the focusing space S. Yes. Further, the knot mechanism 10 and the discharge mechanism 11 that are synchronized with the needle 7 are also stopped in a standby state.

  When a predetermined amount of waste straw is converged in the converging space S, the sensing door 8 is moved backward by receiving a converging pressure equal to or higher than a set value generated by the scrambling operation of the scrambling packer 6, thereby causing the one-turn clutch Becomes ready to start. Then, in synchronization with the next scraping operation of the scraping packer 6 (final scratching operation), the one-rotation clutch is engaged and actuated at a predetermined timing to start driving the needle 7 and drive the knot mechanism 10. Force transmission is started.

  When the scraper packer 6 performs the final scraping operation, the needle 7 crosses the drainer carry-in path from below through the space where the scraper is pushed back and forth by the scraper packer 6, and the knot mechanism 10 Passing the string guide plate 12 disposed below, the bundled string having one end held by the string holder 10b of the knotting mechanism 10 is supplied to the knotting mechanism 10 while being wound around the drainer of the converging space S from the front. To do. The knot mechanism 10 operates in synchronism with the string supply operation by the needle 7, and knot operations such as knotting the string by the knot building 10a, cutting the supply string by the string holder 10b, and holding the cut end are sequentially performed. .

  Thereafter, the discharge arm 13 of the discharge mechanism 11 that operates in synchronism with the knot mechanism 10 pushes and moves the binding brace backward, and accordingly, the binding string is pulled out of the knot building 10a to form a knot, and the subsequent discharge arm 13 continues. As a result of the backward movement, the straw bundle R is discharged backward from the converging space S. At this time, the sensing door 8 is retracted downward to open the rear outlet of the converging space S.

  When the knotting mechanism 10 completes the knotting operation and the new cut end of the bundling string is held by the string holder 10b, the needle 7 moves backward, and the needle 7 returns to the standby position below the focusing space S. At this time, the one-rotation clutch is automatically disengaged and the needle drive is stopped, and the sensing door 8 is raised and returned to the original sensing position, thereby completing one bundling operation, and the subsequent drainer continues. It will be focused.

  The detailed configuration of each part in the waste straw binding device B configured as described above will be described below.

  As shown in FIG. 4, the auxiliary packer 9 that first scrapes and conveys the waste straw is disposed at an appropriate distance away from the binding action position on the waste straw stocker side, and is supported sideways. In FIG. 5, a crankshaft 16 that is always rotated counterclockwise, a pair of left and right crank arms 17 connected to both ends of the crankshaft 16, and a device fixing portion are mounted so as to be able to swing back and forth about a fulcrum b. The swing arm 18 and a packer arm 19 made of a plate material pivotally connected to the free end of the crank arm 17 and the free end of the swing arm 18 are configured. Then, the tip of the packer arm 19 circulates and rotates with a long trajectory back and forth by the crank operation accompanying the rotation of the crank arm 17, so that the waste straw is scraped and conveyed toward the working area of the packer 6. ing. Of the pair of left and right packer arms 19, the packer arm 19 positioned on the side of the waste straw tip is configured in a left-right dual system.

The crankshaft 16 is attached with a circular drum-shaped rotating body 20 having a larger diameter than the crank arm diameter, and prevents the waste from being wound around the crank mechanism. Moreover, rotor 20 that rotates together with the crankshaft 16, the outer peripheral surface of the rotor 20 serves the function of Komu sends exhaust straw rearwardly.

  In addition, between the left and right packer arms 19, a waste wall presence / absence sensor 21 made up of a limit switch is provided hidden inside the outer diameter of the rotating body 20. The waste straw presence / absence sensor 21 is operated by a sensing lever 22 that enters the waste straw carrying-in path and swings back and forth. The sensing lever 22 is pushed by the transport waste wall and swings backward. The presence of the exhaust straw is detected by the movement, and while the presence of the exhaust straw is detected, the hitting plate 5 of the stock sorting apparatus D is automatically activated based on the detection of the stock edge position of the incoming waste straw. When the left and right screw feed control is performed by the electric motor 23 so as to be the optimum hitting position corresponding to the length of the waste straw, and the stoppage of the waste straw is detected by the forward return of the sensing lever 22, the stock edge position Regardless of the detected information, the hitting plate 5 is held at the current position. In other words, when the combine machine reaches the headland and the subsequent discharge of the waste straw stops, the stock end position detection means determines that it is short and the hitting plate 5 is controlled to move to the movement limit on the tip side. By stopping the action position control of the hitting plate 5 when there is no waste straw as described above, it is possible to perform stock edge hitting at a suitable position from the beginning when the waste straw is carried in next time. .

  As shown in FIG. 5, below the convergence space S, a waste wall support member 25 made of a round bar closes to the lateral side of the movement locus of the needle 7 so as to receive the supplied waste wall from below. The deployment is fixed. The exhaust wall support member 25 extends from the rear rear outlet of the converging space S to the front beyond the front inlet, and corresponds to the start end portion of the converging space of the exhaust wall support member 25 and the needle 7. The stepped portion 25a is bent and formed immediately after the passing locus.

  According to this configuration, the waste straw supplied to the inlet portion of the waste straw binding device B is received and supported by the waste straw support member 25 from below, and then received in the converging space S due to the scraping action of the scraping packer 6. Since the converging space S has a large vertical width due to the drop step portion 25 a of the discharge wall support member 25, the discharge wall is pushed and supplied to the converging space S by the scraping packer 6. Falls at the falling step portion 25a, and the backward flow to the front (in the direction of the entrance to the converging space) is prevented by the dropping step portion 25a.

  Further, a transport deck 26 made of a flat plate is provided on the waste straw stocker side from the waste straw support member 25, and the height of the waste deck receiving edge of the transport deck 26 is the stepped-down portion of the waste straw support member 25. It is set at a position that is lower than the bottom surface of 25a, and the stocker side of the waste straw that has been fed into the converging space S beyond the drop step 25a is received and supported from below by the lower transport deck 26. Thus, the bulky stock side compared to the tip side is received low by the transport deck 26, so that a large amount of waste straws can be stably converged without moving.

  Above the converging space S, a separation spring 27 and a support spring 28 made of a curved leaf spring material are respectively arranged in a cantilever direction facing backward. The support spring 28 is disposed to face the transport deck 26 and receives the focusing exhaust wall at the rear part of the focusing space S, and prevents the discharging wall from escaping backward from the focusing space S during the focusing operation. At the same time, when releasing the bundle, it can bend upward and escape. Further, the separation spring 27 is disposed on the stock end side with respect to the support spring 28, and allows the passage of the waste straw supplied by being fed into the converging space S by upward elastic deformation, but the straw bundle is released. At the same time, the trailing end of the unbound binder is dragged by the bundle of straws and is prevented from being scraped by the spring tip.

  A brace receiving plate 14 made of a leaf spring material is mounted on the front surface of the sensing door 8. The brace receiving plate 14 is normally in a cantilevered posture toward the upper front, and in this forward projecting posture, the condensing drainer is received and the converging pressure is transmitted to the sensing door 8. When the amount of waste straw collected by the last scraping operation by the scraping packer 6 when the needle is fed to the string by detecting the convergence pressure of the needle, the brace receiving plate 14 is elastically deformed backward to cause abnormal convergence pressure. Increase is suppressed.

  As shown in FIG. 6, a pair of ribs 12a for preventing the introduction of a drainer is provided on the lower surface of the string guide plate 12 located above the converging space S, and a needle passage hole 12b is provided between the pair of ribs. Is formed. The scraper packer 6 is disposed so as to face the string guide plate 12 from below.

  The scraper packer 6 includes a pair of left and right packer arms 31 a and 31 b formed wide in the front-rear direction and a scraper arm 32 made of a bar, and both the packer arms 31 a and 31 b are arranged on the left and right sides of the string guide plate 12. The scraper arm 32 extends from the stocker-side packer arm 31b so as to act at a position farther to the waste straw stocker side than the transport deck 26. Has been.

  An intermediate portion of the packer arms 31a and 31b is pivotally connected to the free end portion of the crank arm 34 fixed to the constantly rotating packer drive shaft 33, and is mounted on the device fixing portion so as to be swingable around the fulcrum c. The free end portion of the moving arm 35 and the lower end portions of the packer arms 31a and 31b are pivotally connected, and the distal ends of the packer arms 31a and 31b circulate and rotate with predetermined trajectories Pa and Pb by the continuous rotation of the crank arm 34. The waste straw sent by the auxiliary packer 9 is sent toward the converging space S.

  Here, the tip of the stocker side packer arm 31b is set lower than the tip of the tip side packer arm 31a, and the tip locus Pa of the tip side packer arm 31a extends to the upper side from the lower end of the rib 12a of the string guide plate 12. On the other hand, the tip locus Pb of the stocker side packer arm 31 b passes near the lower end of the rib 12 a of the string guide plate 12. According to this, the minimum interval t2 between the tip locus Pb of the stocker side packer arm 31b and the lower surface of the string guide plate 12 is smaller than the minimum interval t1 between the tip locus Pa of the tip side packer arm 31a and the lower surface of the string guide plate 12. Therefore, when the waste straw is scraped into the vicinity of the string guide plate at the tip of each packer arm, the bulky waste straw stocker side is pressed against the string guide plate 12 and the rib 12a with an excessive force. Therefore, even when a high flow rate of the waste straw transporting is performed, the waste straw biting lock phenomenon is avoided in advance between the scraping packer 6 and the string guide plate 12.

The needle 7 is mounted so as to be rotatable about a door shaft 36, and a driving arm 38 provided on the needle driving shaft 37 and the needle 7 are interlocked and connected by an interlocking link 39. needle drive shaft 37 by one revolution clutch (not shown) is placed is activated, the needle 7 is Yue forte cord focusing space S swings upward from the waiting position by the rotation of the first half of the drive arm 38 is rotated 1 A supply operation is performed, and the needle 7 swings downward by the second half rotation of the drive arm 38 and returns to the original standby position.

Here, the operation timing of the scraping packer 6 and the needle 7 is set as follows. That is, as described above, the needle 7 basically moves in the gap where the pair of left and right packer arms 31a and 31b in the scraping packer 6 scrapes the waste wall back and forth, but as shown in FIG. When the tip of the packer arm 31a reaches a position corresponding to the lower end of the rib 12a of the string guide plate 12, the needle 7 passes over the packer 6 and reaches a position corresponding to the lower end of the rib of the string guide plate 12. In addition, the operation timing of the needle 7 is set slightly earlier than before.

  By doing so, the back and forth widths of the packer arms 31a and 31b in the scraper packer 6 are made smaller than before, and the back surface of the needle 7 is prevented from being exposed to the waste wall conveying path, and thus the packer arm 31a. , 31b and the back of the needle 7 are prevented from being sandwiched.

  The release mechanism 11 is supported so as to be swingable around a crank arm 42 that is loosely fitted around a drive shaft 41 of an intermittent drive gear 40 that drives the knot mechanism 10 so as to be rotatable around an axis P1, and a fixed fulcrum P2. And the discharge arm 44 pivotally connected across the tip fulcrum P3 of the crank arm 42 and the tip fulcrum P4 of the swing arm 43. The discharge arm 44 includes a plurality of plate members. The discharge arm main body 44a is configured to be fixed in parallel to a pipe member 44b bent into an L shape. The crank arm 42 rotates counterclockwise in the drawing around the axis P1 so that the tip of the discharge arm 44 draws a constant circular rotation trajectory K extending from the front part to the rear part of the converging space S. Has been.

  The intermittent drive gear 40 is provided with a drive pin 45 that interferes with the rotation trajectory of the crank arm 42, and the crank arm 42 is abutted and pressed by the drive pin 45 so as to be rotationally driven in the above direction. It has become. A folding spring 46 is stretched between the fulcrum P2 of the swing arm 43 and the discharge arm 44. A compression coil bar 47 is attached to the drive pin receiving portion of the crank arm 42 so as to reduce impact and contact noise when contact driving by the drive pin 45 is started.

The release mechanism 11 has been constituted as described above will be described with its discharge operation below.

As shown in FIG. 3 , the intermittent drive gear 40 is held at a constant rotational phase during exhaust fan focusing, and in this case, the crank arm 42 is in a pre-rotated position with respect to the drive pin 45 located at the origin b0. is there. That is, the tip of the discharge arm 44 stands by at the storage position a0 below the front part in the circulation rotation locus K.

  The drive gear 40 rotates counterclockwise for the knot drive, but the drive pin 45 does not press the crank arm 42 for an initial fixed period, so the release mechanism 11 maintains the standby posture. Then, when the knot operation proceeds and the drive pin 45 reaches the position b1, the crank arm 42 starts to press and rotate. As shown in FIG. 4, the discharge arm 44 advances counterclockwise from the storage position a0 and converges. The space S is moved backward, and the binding straw is pushed backward.

  As shown in FIG. 5, when the drive gear 40 rotates once and the drive pin 45 reaches the origin b0, the discharge arm 44 and the like move in advance due to inertia, and the crank arm 42 moves away from the drive pin 45.

Then, as shown in FIG. 9 , when reaching the dead point DP in which the axis P <b> 1 of the crank arm 42, the tip fulcrum P <b> 3, and the tip fulcrum P <b> 4 of the swing arm 43 are aligned, The tension acts in a direction that promotes refraction of the swing arm 43 and the discharge arm 11, and the tip fulcrum P3 of the crank arm 42 moves in a direction beyond the dead point DP. When the tip fulcrum P3 exceeds the dead point DP, the tension of the folding spring 46 acts in the direction in which the swinging arm 43 swings in advance (clockwise in the drawing), and the entire release mechanism 11 is moved by the folding spring 46. It is folded into the original storage state shown in FIG. At this time, the release arm 44 is correctly returned and held at the storage position a0 by contacting the stopper pin 48 of the drive gear 40 with the crank arm 42 stopped.
