Reference numeral 9 denotes a control seat, which is disposed above the engine, and control members such as control levers and instruments are collectively provided in a control operation frame 10 on the front side and left side of the engine. 1
Reference numeral 1 denotes a cutting and conveying device, which is a front side vertical conveying device that collects the harvested culms collected by the weeding device 12, the pulling device 13, the cutting blade device 14, the scraping device 15, and the left and right scraping devices 15 and vertically conveys them. A chain 16, a stock-holding / conveying chain 17 that takes over the grain stalk being conveyed from the front vertical conveying chain 16 and conveys it upward and rearward;
And a configuration equipped with a tip conveying device 18 and the like for causing the tip side of the grain culm being transferred to the upper rear side to engage and transfer while moving backward, so that the tip side falls to the right side and changes the posture to the lying state. It has become. The stock transfer chain 17 is located on the rear upper side of the drive sprocket 21 attached to the drive shaft 20 of the transmission vertical tube case 19a on the frame 19 side of the reaper transfer device 11, and is separated from the left and right. Driven sprockets 22, 23
And wrapped around. And this stock transfer chain 17
An electric cylinder for driving a mounting frame 24 for supporting each of the winding sprockets with a servo motor M1.
At 25, the rotation of the drive shaft 20 around the axis thereof can be adjusted. That is, the cereal stem holding / conveying section (a) is rotated left and right in plan view. Reference numeral 26 denotes a clamping rod which is configured to support the grain stem clamping and transporting section (a) of the chain 17. Reference numeral 27 denotes a handling depth detecting device which is configured to detect the position of the tip of the grain stem supplied to the supply port 6 of the threshing machine 4 and usually hangs at a predetermined interval above the entrance of the supply port 6. Switches SW1, connected to the actuator
SW2 and SW3 are provided to detect what actuator is touching the tip of the grain stalk, and when the switch SW1 is turned on by the contact of the actuator from the ear tip side, deep handling is performed. On the contrary, when the switch SW3 connected to the actuator from the stock source side becomes "OFF", it is determined that the handle is shallow, and the switch SW2 connected to the left and right middle actuator is "ON".
This is a detection device that is set to have an optimum handling depth when it is repeatedly turned “off”. The servomotor M1 is driven and controlled by the detection signal of the handling depth detecting device 27 to rotate the mounting frame 24 of the stock transfer chain 17 so that the grain stalk being conveyed. The first handling depth automatic adjustment means A for automatically adjusting the position at which the stock is transferred to the supply chain 5 on the threshing machine 4 side is provided. On the other hand, separately from the first depth-of-depth automatic adjusting means, the direction of holding and transferring by the stock transfer chain 17 is changed so that the base of the grain stalk during the transfer is separated from the threshing feed chain 5. There is provided a second automatic handling depth adjusting means B which is opened and inherited. In a specific embodiment, a support shaft 28 of the driven sprocket 23 is mounted on a frame 24 via a swing arm 29, and the arm 29 is attached to a servomotor.
Rotation is adjusted by the electric cylinder 30 driven by the table M2, and the culm being transported is moved away from the direction of the arrow (b) approaching the supply port 6, and the holding stock is quickly moved in the direction of the arrow (c) on the right side. It is configured so that it can be transferred to Further, in the control by the first automatic handling depth adjusting means A, when the handling depth is controlled to the maximum handling depth at the time of ultra-short culm, the position of the base end of the stock in the rightward direction is controlled. The servo motor M is detected by a detector 31 for detecting a limit.
1 is stopped to limit the deep handling side control, thereby preventing the stockholder from being caught by the threshing feed chain 5. When the detector 31 detects that the detector 31 has reached the deep-handling-side limit control,
The signal from the detector 31 is ignored, and the tip side is controlled to the deep handling side until the switch SW3 for shallow handling determination is turned on. In other words, the second automatic handling depth adjusting means has a structure in which the threshing feed chain 5 determines the position of the limit dimension close to the tip from the base end of the stock and clamps and transports it during normal work, while holding the grain culm by the threshing feed chain 5. The ultrashort cereal culm which cannot be pinched ignoring the assurance that this is ensured is supplied directly to the handling room of the threshing machine 4 without pinching, thereby preventing unhandled stalks. Although the second automatic handling depth adjusting means B in the above example is configured to adjust by changing the direction of the transporting direction,
As shown in FIG. 3 and FIG. 4, deep handling in which the grain stalk is engaged with the cradle 32 provided in front of the grain stalk supply port 6 on the threshing machine 4 side and is transferred to the back side of the supply port 6 An auxiliary feeding device 33 is provided, and the auxiliary feeding device 33 can be switched between a state in which the auxiliary feeding device 33 acts on the grain stalk to promote deep handling and a state in which the auxiliary feeding device 33 is retracted below the cradle 32 and does not act. This switching is performed by the electric cylinder 34 by the servomotor M3. In addition,
Various methods are conceivable, but in any case, when the deep handling side control by the first handling depth adjusting means A is in a state where the culm length of the grain culm is extremely short and unhandled, the second handling depth adjustment is performed. Even if the means B is operated and the holding by the supply chain 5 on the threshing machine 4 side becomes uncertain, priority is given to prevention of unhandled portions, and a deeper handling state is set. To explain the operation of the above example, when harvesting rice and wheat to be harvested in a field, while the combine is running on its own and the culm is divided by the weeding device 12,
The falling grain stem is caused by the raising device 13, and thereafter,
The root of the stock is cut by the cutting blade device 14. Then, the cut cereal stem is scraped toward the left and right center by the scraping device 15, held by the front vertical transport chain 16 and its clamping rod, and transferred to the upper rear side. Thereafter, the stock is held by the stock-holding / conveying chain 17 and the holding rod 26, and the stock is held and further moved upward and rearward. Also, at this time, the tip side wand is connected to the tip transfer device 18.
At the same time as being transported to the upper side by locking with the engaging lug, gradually lower this spike side from the right, change the posture of the grain culm to the sideways state, and at the grain culm transfer terminal end side A state close to a substantially horizontal plane is assumed. The stem of the grain culm that has reached the transfer end is passed to the feed chain 5 of the threshing machine 4 and cooperated with the clamping rod to leave the stem of the grain culm as it is on the threshing machine 4. Is transported rearward along the left outside of the. Therefore, the spike tip side is supplied into the handling room from the supply port 6 opening to the front side of the threshing machine 4, threshing and sorting by rotation of the handling cylinder, and the grains are stored in the Glen tank 7. On the other hand, the straw waste is discharged from a waste dust port opened behind the threshing machine 4, and the waste is transported backward by the supply chain 5 and discharged as it is to the field or cut and discharged by a cutter or the like. . The cereal culm supplied to the supply port 6 is detected by the handling depth detecting device 27 as to whether or not the tip side thereof is at an appropriate position for threshing. That is, the position of the front end passing position is detected by the actuator that hangs downward, and the position where the tip passage position is on the left and right is detected. When the switch SW1 connected to the actuator detects the grain culm, it is in the deep handling state. Judgment is made, a signal is issued, and the servomotor M1 is operated to operate the electric cylinder 25.
The frame 24 on the side of the stock transfer chain 17 is rotated in the direction of arrow (d) in plan view to control it to the shallow side. Conversely, when the switch SW3 connected to the actuator is turned off without passage of the grain stalk,
It is determined that the state is a shallow handling state, and a signal is output.
1 is operated to retract the piston 25a of the electric cylinder 25, and the frame 24 on the stock transfer chain 17 side is turned in the direction opposite to the arrow (d) in plan view to control it toward the deep handling side. Then, control is performed such that the switches SW3 and SW2 are always on or at least the switch SW3 is kept on. However, in order to maintain the switch SW3 in the ON state, it is necessary to provide a condition that ignores the assumption that the root side of the cereal stem is taken over by the supply chain 5. That is, in the case of the ultrashort culm, in order for the tip to contact the actuator on the leftmost side and to turn on the switch SW3, it is necessary to prepare for a state in which the spike is not clamped by the supply chain 5. Therefore,
Generally, a detector 3 for detecting whether or not a stock is present in order to transport the product while being tightly held by the supply chain 5.
When the detector 31 does not detect the passage of the grain stem, the operation control by the electric cylinder 25 of the stock transport chain 17 is immediately stopped and the stock side always has some margin. Are transported by the supply chain 5. However, in the above-mentioned ultrashort culm grain culm,
The tip side is transported in a state where it does not sufficiently enter the handling room, and the handling remains without contacting the teeth handled by the handling cylinder. In such a case, it is considered that it is better than the unharvestable state due to unhandled material even if the grain stalk is dragged in the handling room to some extent, so that the tip of the switch SW3 does not contact the leftmost actuator.
Is turned off, and the automatic control of the first depth-of-depth automatic adjustment device A is stopped by the detector 31, the second depth-of-depth automatic adjustment means B is operated, and the second depth-of-depth automatic adjustment unit B is operated to the deep-handing side. That is, the electric cylinder 30 is actuated by the servomotor M2 to rotate the sprocket 23 inward through the swing arm 29, thereby moving the grain culm being transferred to the arrow (b).
From the direction to the direction of the arrow (c). Therefore, the grain stalk is transported further to the left from the previous transport direction, and the culm is eventually in a deep handling state. As described above, when the deep handling side control by the first automatic handling depth adjustment device A is not performed,
With the second handling depth automatic adjustment control, it is possible to set a slightly deep handling state, and it is possible to prevent the remaining handling. The structure of the scraping device 15 of the reaper 11 will be described in detail. The scraping device 15 plays a role of gathering the seeds that have been raised in advance by the pulling device 13 after weeding the stalks of the field, and the clogging easily occurs at the time of the scraping, so that the former stage of the harvesting conveyance is performed. This is a department that often causes problems. For this reason, it is desired to easily remove the clogged grain stalks in a configuration that prevents clogging in advance or when clogging occurs, but a configuration that solves this problem has hitherto been proposed. I did not find it. Then, the following means can be considered. As shown in FIG. 5, a plurality of grain squeezing gears 41, 4 are arranged side by side in a horizontal view in plan view.
The support shafts 41a, 42a, 43a, 44a, 4
5a, 46a, and the gears 41, 46 at the left and right ends and the middle gear 44 at the left and right sides are driven by the front vertical transport chains 16a, 16b, 16c by sprockets 47, 48, 49 integrated with the support shafts of these gears. It is configured to be driven. In addition, each of these scraping gears 41-46
On the upper surface side of the body, cylindrical bodies 50, 51, 52, 53, 54, 55 are configured so as to cover the shafts so that the grain stems do not become entangled with the shafts. Further, pulleys 56, 57, 58, and 5 fixed to the support shaft are provided on the upper portions of these cylinders.
9, 60, 61 are provided, and a driven pulley attached to a support shaft provided on a free end side of a cover body 62 rotatable on the support shaft.
A belt 63 with a rag for scraping is wound around the rims 56a, 57a, 58a, 59a, 60a, 61a. The free end side of each cover body 62 is attached to the frame 19 side through a flexible component so as to be able to move freely in the left and right directions. The driven gear 42 meshing with the driving gear 41, the driven gear 43 meshing with the driving gear 44, and the driven gear 45 meshing with the driving gear 46 among the scraping gears thus configured are all provided. The driving gears 4 are located on the same or upper and lower planes where they do not come out of engagement with each other.
A set of gears of the driven gear 43 meshing with the gear 4 is disposed so as to be vertically displaced from the other sets of gears, and is not located on the same plane as the gears set on the left and right sides. This means that the driven gears 42, 43, 45 can escape to the opposite side to the driving gears 41, 44, 46 meshing with them. As an example of the escape moving configuration, as shown in FIG. 6 and FIG. 7, the mounting fixed frame 64 on the raking side mounted on the frame 19 side of the reaper transporting device 11 includes:
An integral support frame 65 is movably provided on a metal portion rotatably receiving a support shaft, and is configured to be set with a fixing pin 66. In this case, if the driven gear is disengaged from the drive gear by removing the pin 66 and the driven gear is disengaged, the grain stalk clogged in the engaged portion can be easily removed. Further, as another example, if the set configuration by the pin 66 is stopped and the driven gear is elastically held on the drive gear side by the spring 67 as shown in FIG. Even if clogging does not occur because it escapes against the spring 67 and clogging occurs,
The clogged grain culm can be easily removed.
