As shown in FIG. 2, the pair of left and right conveyor belts 2 and 2 are driven in two stages, upper and lower, with the conveyance end portion side pivoted on the upper part of the support cylinder 18 provided on the table 15 at the lower part. The pulleys 19 and 19 are wound around, and the conveyance start end side is wound around floating pulleys 20 and 20 that are pivotally mounted on the front end portions of the upper and lower two-stage support frames 4 and 4. Then, as shown in FIG. 2, the pair of left and right conveyor belts 2 and 2 are lowered so that the conveyance lug 17 reaches near the ground surface on the conveyance start end side, and the conveyance terminal end side is raised and inclined in a side view. It is composed. In the case of the embodiment, the pair of left and right transport belts 2, 2 are constructed with a slight step up and down on the left and right sides, and project inward from both outer sides. The conveyance lugs 17 intersect each other vertically (overlapping in plan view and can pass through the same conveyance path). With this configuration, the left and right transport lugs 17 are characterized in that they can avoid interference and collision during rotation.

  The support frames 4 and 4 supporting the pair of left and right transport belts 2 and 2 are provided with the rear end portion connected to the support cylinder 18 as shown in FIGS. With the rear portion serving as a rotation fulcrum P (transmission shaft), the conveyance start end side rotates left and right.

  The left and right support frames 4 and 4 are connected to each other at the bottom of the transport passage through a connecting member 21 that extends downward by connecting the two upper and lower support frames. A parallel link mechanism is configured by pivotally connecting the left and right sides with a system 5. In this case, as shown in FIG. 3, the support frames 4 and 4 are composed of the conveyor belts 2 and 2, the upper belt cover, the left and right weed fences 11 and 11 at the front, and the like. The above-mentioned rotation fulcrum P (transmission shaft) can be rotated left and right. The support cylinder 18 is not illustrated in detail, but an arc-shaped long hole is formed on the lower side of the rotating support cylinder 18 and provided on the fixed side (table 15 side). It is configured to be freely engaged and disengaged with a locking screw. Therefore, the conveyor belts 2 and 2 can be adjusted in rotation within the range of the arc-shaped long hole formed in the lower portion of the support cylinder 18 and can be fixed with the locking screw.

Next, the support structure of the gage wheel 13 will be described.
First, as shown in FIGS. 6 and 7, the gage wheel 13 is pivoted on an L-shaped support rod 26 that is pivotally connected to the front portion of the support rod 6 that has already been described and extends forward. A hydraulic cylinder 27 for adjustment is connected to the rear portion of the L-shaped support rod 26. In this case, the L-type support rod 26 and the hydraulic cylinder 27 are provided at a low position, and even if the gauge wheel 13 is adjusted up to the upper limit position, the L-type support rod 26 and the hydraulic cylinder 27 are within the range of a position lower than the upper surface of the transport device 3. It is set as the structure and it considered as the structure which did not disturb the conveyance stem.

  As is already known, the gauging wheel 13 is mainly intended to adjust the cutting height. In the case of the embodiment, as shown in the plan view of FIG. 3 is provided and is configured to be pivoted at the left and right center positions. And although the general purpose combine of an Example is comprised so that the rolling operation | movement of a vehicle body is possible, it has the structure which exists in the virtual center position of the rolling.

  Therefore, in the case of the embodiment, since the horizontal movement of the row cropping device 14 is stabilized during the rolling operation based on the gauge wheel 13 at the virtual center position, the cutting height is not disturbed. In addition, there is a feature that the disc cutting blade 12 stops (there may be thrust into the soil) and there is no cutting residue, and stable cutting is possible.

  And the hydraulic cylinder 27 which adjusts the gage wheel 13 up and down is comprised so that adjustment is possible by the up-and-down switch 28 provided in the operation position of the control seat, as shown in FIG.8 and FIG.9. In the embodiment shown in FIG. 8, the up / down switch 28 is arranged on the side of the steering lever 29, and in the embodiment shown in FIG. 9, the up / down switch 28 is provided on the upper surface of the grip portion of the steering lever 29.

It is said. Therefore, the conveying devices 3 and 3 on both sides are supported by one gage wheel 13 between them, and the vertical cutting height operation becomes easy and stable. Furthermore, since the weed ridges 11 and 11 move forward in the field while being supported by the side gage wheels 13, they hardly rush into the soil surface.

Next, the disc cutting blade 12 will be described.
First, it has already been described that the cutting device 12 is equipped with a disc cutting blade in the case of the embodiment. However, the disc cutting blade 12 of the conveying device 3 as shown in FIG. 10 and FIG. It is configured to be supported integrally on the support frame 4 side, facing from the side (left side) to the path of the pedicle formed by the pair of transport belts 2, 2, and cutting the stock of the pedicle in the field. As shown in FIG. 12, the transmission path of the disc cutting blade 12 inputs the rotational power extracted from the traveling mission device 30 to the hydraulic pump 32 via the transmission device 31, and hydraulic oil is hydraulically supplied through the pipe 33. The motor 34 is driven to drive oil.

  As shown in FIG. 10, the hydraulic motor 34 is installed so as to be retracted outward from the pedicle passage and positioned further outward than the center of rotation of the disc cutting blade 12. As shown in FIG. 11, the disc cutting blade 12 is transmitted by the transmission chain 35. In FIG. 12, reference numeral 36 denotes a hydraulic continuously variable transmission.

  Thus, in the case of the embodiment, the disc cutting blade 12 is configured such that the power input from the hydraulic continuously variable transmission 36 to the traveling mission device 30 is extracted as the cutting power, and the cutting rotational speed is synchronized with the vehicle speed. It has a feature that speed is achieved and a stable cutting action is possible. Since the disc cutting blade 12 constantly changes to a speed following the vehicle speed, there is no abnormal rotation (the cutting blade rotates at a high speed when traveling at a low speed, etc.), and there is no splashing of the soil. There is also an advantage of bringing less soil into the ground. Further, as shown in FIG. 10, the hydraulic motor 34 is in a position retracted from the pedicle path, so that it does not become an obstacle to pedicle conveyance but can also eliminate the cause of entanglement and clogging.

  In the embodiment, as shown in FIG. 11, the disk cutting blade 12 has a rotation sensor 37 attached to the output shaft of the hydraulic motor 34 to measure the rotational speed at all times, and the controller outside the figure. It is set as the structure which inputs to. The controller outputs a control signal to the hydraulic cylinder 27 when the detection value of the rotation sensor 37 falls below a certain number of revolutions to lower the gage wheel 13, and the disk cutting blade 12 is reversed accordingly. In addition, the ascending control is possible. The controller is configured to stop the raising of the cutting blade 12 when the rotation of the disc cutting blade 12 returns to the reference value. Therefore, in the case of an Example, the disc cutting blade 12 has the characteristics which can escape from soil by the said control effect | action and can eliminate clogging.

  In this case, the controller is configured to issue an alarm when the number of rotations of the disc cutting blade 12 falls below a certain value. It is a combine that can.

  In the case of the embodiment shown in FIG. 13, the row cropping device 14 including the disc cutting blade 12 rises on the convex portion when the cage wheel 13 runs on the uneven surface of the field. A potentiometer 38 is provided at the base of the support rod 6 of the wheel 13 so as to measure the rising angle. And the disc cutting blade 12 is set as the structure which rotation stops automatically, if it raises to the position of the virtual line U in FIG. Therefore, the disc cutting blade 12 has an advantage that the soil is not splashed from the high position to the lower table 15 side at the rear, and the quality of the harvested beans is not deteriorated.

  Further, in the case of the embodiment of FIG. 11, the controller installs an impact sensor 39 on the lower rotation side of the disc cutting blade 12 to detect the amount of soil discharged as the cutting blade 12 rotates. When the input and the soil over a predetermined amount, the disc cutting blade 12 is raised. As described above, in the row cropping device 14 according to the embodiment of the present invention, the disc cutting blade 12 mainly connects the hydraulic cylinder 27 that moves the gage wheel 13 up and down and the controller (not shown). The control is made up and down to perform various controls to ensure the safety of work and the commercial value of the beans to be harvested.

Next, switching of the conveyance speed and shifting of the low crop device 14 will be described.
In general, the combine cutting pre-processing device 10 (the row crop device 14) shifts in accordance with the vehicle speed from the start point (0 start) (see FIG. 14) and has a constant conveyance at the beginning of the operation (see FIG. 14). There is known a vehicle speed following type in which a speed is maintained and a speed is changed by following the vehicle speed at a higher speed than the speed (see FIG. 15). The former is effective when the field stalk is lying down, and the latter is suitable for a normal stalk trimming operation in an upright state.

  First, as can be seen from the transmission mechanism diagram shown in FIG. 16, the low crop device 14 splits the rotational power output from the engine 40 into two systems, the gear case 41 side and the hydraulic continuously variable transmission 36 side. The transmission shaft 42 is transmitted to the input shaft 44 from one of the transmission path 42 via the traveling mission device 30 and the other transmission path 43 output from the gear case 41. In this case, as shown in FIG. 16, the input shaft 44 is provided with a one-way clutch 45 at a midway position between the two transmission paths 42 and 43 so that high-speed rotational power is input and transmitted.

  The gear case 41 is a mechanism for shifting the rotational power input from the engine 40 to a constant speed (a constant initial speed shown in FIG. 15) by the three transmission gears 46, 47, 48, 49. The clutch device 50 is configured to transmit to the transmission path 43 when the clutch device 50 is turned on or off. Accordingly, as shown in FIG. 16, the transmission path 43 is transmitted at a constant speed to the transmission path 43 side when the clutch device 50 is operated, and from the speed following the vehicle speed transmitted from the traveling mission apparatus 30 side. Only when the speed is high, the low crop device 14 is transmitted via the input shaft 44.

  As described above, in the embodiment of the present invention shown in FIG. 16, whether the low-crop device 14 is set to the vehicle speed tracking speed of FIG. 14 or the vehicle speed tracking type of FIG. The configuration is selectable. Therefore, the pre-cutting processing device 10 (the row cropping device 14) can change the speed (see FIG. 14) following the vehicle speed from the start time point (0 start) according to the level of stalks lying in the field. At the beginning of the work, a constant conveyance speed is maintained, and it is possible to select whether to shift the speed higher than the speed following the vehicle speed (see FIG. 15) and to perform the work accurately according to the degree of lodging. .

  As shown in FIGS. 17 and 18, the general-purpose combine according to the present embodiment is equipped with a direction sensor 51 on the weed pod 11, and the pedicle plant stock (see A in FIG. 18) and the field culm. (Refer to FIG. 18B) and a shape and length that can be detected and connected to the controller of the direction control mechanism. Therefore, the general-purpose combine of the embodiment has an advantage that the directional control is automatically operated to advance along the row of planting rows of stems or the rods on which the stems are planted, and the cutting and threshing work can be facilitated.

  Next, in the row cropping device 14 according to the present embodiment, as described above, the hydraulic motor 34 for driving the disc cutting blade 12 is provided with the pipe 33 for circulating the hydraulic oil from the hydraulic pump 32, Other harnesses are planned.

Further, as shown in FIG. 22, the transport cover 54 and the rear cover 55 match the shape of the surface that guides the transport stem to prevent the stem stem from being caught (the transport lug 17 side), and contact guidance is provided. The surface is formed in an arc shape so that the resistance to the pedicle can be reduced and the guide can be smoothly guided to the rear side of the scraping organ 1.

Therefore, the stems that have reached the end of the transport device 3 are smoothly transported backward without being disturbed in the transport posture and supplied to the scooping agar 1.
Next, as shown in FIG. 24, the conveying device 3 according to the embodiment of the present invention is configured such that the outermost conveying belt 2 can be rotated and opened outward together with the support frame 4. In this case, the support frame 4 is configured to be able to rotate about the rear support cylinder 18 (rotation fulcrum P) by removing the connection frame 5 that has been connected sideways as described above.

  As described above, according to the embodiment of the present invention, as shown in FIG. 24, the outermost conveyor belt 2 is integrated with the support frame 4 so as to be rotated outward and opened. A wide maintenance space can be formed, and there is an advantage that clogging can be removed and other maintenance can be easily performed.

Next, the clogging detection device 57 of the transport device 3 will be described.
First, as shown in FIG. 25 and FIG. 26, the clogging detection device 57 includes a safety switch 60 that detects an abnormality using a support guide 59 provided along the path below each conveyance lug 17. doing. That is, as shown in FIG. 26, the safety switch 60 is configured to detect the abnormal state by moving the switch against the tension pressure of the tension spring 61 when the support guide 59 is pressed and turning on the switch. In this case, the clogging detection device 57 is configured to issue an alarm when the safety switch 60 detects an abnormal state.

As described above, the embodiment of the present invention is characterized in that when an abnormality such as clogging occurs in the stalk transporting device 3, an alarm is immediately issued, damage to the mechanical device can be prevented, and safe work can be performed. .
Next, a pedicle guide guide 65 for guiding the pedicle guide from the end portion of the transfer device 3 to the scooping ager 1 side above the table 15 of the pre-cutting processing apparatus 10 will be described with reference to FIGS. Three examples will be described based on the above.

  First, as shown in FIGS. 27 and 28, the stem guide guide 65 of the first embodiment is provided with an upper guide 65a and a lower guide 65b at the end portion of the transport device 3 on the side far from the elevator 16.

Example 1
Next, another embodiment 1 will be described with reference to FIGS.
Another embodiment 1 relates to a general-purpose combine receiving network 70 by increasing the amount of leakage from the handling chamber 71 and reducing the loss of dust scattered outside the machine as much as possible.

  First, as shown in FIG. 35, the receiving net 70 is arranged in a direction in which threshing is carried around by the handling cylinder 73 in the handling chamber 71 when arranging a plurality of leakage holes 72 having a long hole shape on the mesh surface. It is configured along the short side. That is, the threshing in the handling chamber 71 is spirally carried along the outer periphery with the rotation of the handling cylinder 73 by the handling teeth 74 that are planted in a spiral shape in a plan view. The leakage hole 72 is configured by arranging the long side in an orthogonal state with respect to the moving direction.

In this case, as shown in FIG. 35 and FIG. 36, the receiving net 70 is formed as a hollow iron plate and stretched in the handling chamber 71.
In the conventional receiving net, the leakage hole was formed in a round hole, so in the case of harvesting legumes with many leaves (for example, at the time of gold), the leakage hole is blocked by the leaves when harvesting beans. As a result, there was a significant reduction in dust loss that was scattered from the dust outlet to the outside of the machine.

  On the other hand, in the first embodiment, the threshing in the handling chamber 71 receives a relatively large resistance on the long side of the leakage hole 72 which is a long hole and is subjected to a degranulating action. It can leak from the lower hole 72 to the lower sorting chamber 77, and since it is a long hole, it is less likely to be blocked by leaves, and the leakage of the first grain from the handling chamber 71 is greatly increased. There are features.

  In general, in the case of general-purpose combine, the second mower 80 has a first mower that cuts the upper part (ears, beans) at the top of the pedicles in order to reduce the burden of the full-throwing type threshing device. It is supplied to the threshing machine, put into the threshing device, and the intermediate part remaining in the field, the stems on the side of the stock are cut off and dumped in the field. Therefore, the second mower 80 exhibits its original function when the pre-cutting processing device 81 is located at the reference height (position B in FIG. 37), and is on the ascending side (stops the operation) from that position. ) Or on the descending side (position where low mowing is possible with the first mower 83), it is automatically raised and stored in the upper non-working position. The second mower 80 is the same when the ground sensor 89 mounted on the lower side of the table 88 reaches a position where it grounds.

As described above, in the second embodiment, when the pre-cutting processing device 81 moves up and down in advance around the reference height, the second mower is automatically stored upward, so that the second mower is soiled. It has the effect that it can protect and avoid colliding with a crawler. The ground sensor 89 can be manufactured at low cost by using a height detection sensor conventionally used for height control.
