  Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  1 to 4, FIGS. 5 to 8, and FIGS. 9 to 12 show the combine in different states. This combine is provided with a pair of left and right traveling crawlers (traveling devices) 2, 2 at the bottom of the traveling vehicle body 1, and a threshing device 3 and a grain tank (grain storage device) G are provided side by side on the upper side of the traveling vehicle body 1. A driving operation unit T including a driver's seat 5 and an operation box 6 is provided on the front side of the Glen tank G, and a reaping device 4 is provided in front of the driving operation unit T and the threshing device 3.

  The reaping device 4 is composed of herb bodies 7, 7... That divide the cereal planted in the field to the left and right, and four husk erecting devices 8, 8 that elevate the cereal shed after the weeding path K. 8, 8 and cutting blade device 9 that cuts near the root of the culm after raising, and harvests the culm, and the rear side of the cereal after the weeding through the cutting blade device 9 The take-up conveying device 10 that conveys to the threshing device and the lifting and conveying supply device 11 that changes the posture while taking up and conveying the cereal straw after the carry-in conveyance and supplies it to the threshing device 3 are provided.

  The reaping device 4 is equipped with a reaping main frame 21 so as to be movable up and down with respect to the traveling vehicle body 1. More specifically, the cutting main frame 21 is configured to rotate up and down with a cutting input shaft 23 provided on the cutting suspension base 22 as a fulcrum, and the cutting device 4 moves up and down by the expansion and contraction operation of the cutting lifting cylinder 24. It is like that.

  The pulling device 8 is driven endlessly by being wound around front and rear pulling cases 12 and 13 that can be divided into front and rear, and an upper drive sprocket (not shown) and a lower driven wheel that are housed in the pulling cases 12 and 13. And a pulling lug 14 attached to the pulling chain at a predetermined interval. The pulling lug 14 protrudes from the pulling cases 12 and 13 to the side on the pulling path K side and raises the cereal when the pulling lug 14 moves upward and obliquely upward as the pulling chain is driven. The front pulling case 12 is configured to be detachably attached to the rear pulling case 13, and when it is pulled upward, the locked state is released and can be removed to the front side. The front face of each front raising case 12, 12,... Is bent so that the upper end portion 12u is in a rearward inclined posture with a gentler slope than the lower portion, and the operator's line of sight is indicated by a two-dot chain line in FIG. As shown, the field of view in the vicinity of the weed position of the weed bodies 7, 7... In the work in the sitting position is good, and the weed position is more visible in the work in the standing position. Reference numeral 12c indicates this bending position.

  The cutting blade device 9 is of a known clipper type, is provided on the tip end frame that protrudes forward from the lower end portion of the cutting main frame 21 that supports the cutting device 4, and the tip side is subjected to the action caused by the pulling device 8, The stocker side is configured to cut the stocker part of the planted cereal rice cake in a state in which the stocker side is subjected to the stir action by the stir transporting device 10.

  After harvesting, the culm is transported rearward by the scraping and transporting device 10 and delivered to the lifting and transporting supply device 11, and the posture is changed in the lifting and transporting process by the lifting and transporting supply device 11. It is delivered and supplied to the threshing device 3. As the lifting and conveying supply device 11, a well-known configuration is adopted in which the stock side is held between a chain and a holding rod, and the tip side is picked up by a transfer lug and transferred.

(cover)
The upper portion of each pulling device 8 is structured to be covered with a cover 15 that is long in the lateral direction. The cover 15 may be formed of a metal plate or a plastic plate such as polycarbonate. In that case, it is preferable that the cover 15 is transparent or semi-transparent to ensure visibility through the cover 15.

  The cover 15 is disposed on the upper extension line of the rising locus of the pulling lug 14 that rises along the pulling path K of the pulling device 8, and the cover 15 moves upward and shifts to the state of covering the front surface of the upper end side 12 u of the front pulling case 12. The tilting posture in the front-rear direction can be freely changed so as to cover the upper portion of the pulling path 14 in the pulling lug 14. And, as the posture changing means of the cover 15, it is possible to adopt a front / rear / up / down slide structure, but in this embodiment, as shown in FIGS. 9 to 12, it is supported on the back side of the pulling device 8 at the left end and the right end. The stays 8s and 8s are respectively erected, and a support shaft 16 extending in the horizontal direction is provided between the support stays 8s and 8s. The cover 15 is rotated up and down around the support shaft 16 as a rotation fulcrum. It is configured to move. The state in which the cover 15 is rotated upward is a posture change state (open posture) covering the upper part of the pulling path K, and the state in which the cover 15 is rotated downward covers the front surface of the upper end side 12u of the front pulling case 12. The posture is changed (closed posture). In addition, a tension spring 17 is provided in the vicinity of the support shaft 16, and the cover 15 can be held in each posture by the tension spring 17 exceeding the fulcrum in the front-rear direction with respect to the support shaft 16. It can be opened and closed with. That is, the support shaft 16 and the tension spring 17 constitute a posture holding mechanism for the cover 15.

  As shown in FIG. 28, the raising lug 14 that protrudes from the raising cases 12 and 13 of the raising device 8 and rises into the raising path K acts on the cereals after weeding from the root side to the tip side. When this occurs, the grain handled by the pulling lug 14 may scatter toward the operator of the driver's seat 5, but the cover 15 is orthogonal to the scattering direction of the grain etc. in a side view. By changing the posture to the open posture, the scattered grains and the like can be effectively blocked by the cover 15.

The cover 15 can have an appropriate shape such as a flat plate. However, as in the present embodiment, the cover 15 has a substantially square shape in a side view so as to include an upper surface cover portion 15a and a rear surface cover portion 15b. When formed, the lower surface portion of the upper surface cover portion 15a can prevent the grains and the like from scattering upward, and the lower surface portion of the rear surface cover portion 15b can prevent the grains and the like from scattering backward and upward. Therefore, it is preferable because it is possible to reliably prevent the grain and the like from being scattered to the driver's seat 5.

  In the open state, the cover 15 is preferably arranged so that the upper surface cover portion 15a is substantially orthogonal to the upward extension line of the rising locus of the pulling lug 14 in a side view, but the rear cover portion 15b is the upper extension line of the rising locus of the pulling lug 14 It is also possible to arrange them so as to intersect with each other. Further, the cover 15 is shifted to the rear side from the upward extension line of the rising locus of the pulling lug 14, and the adjusting body 50 described later is positioned on the upper extension line of the rising locus of the pulling lug 14 by expanding the cover range forward. It is also possible.

  Like the multi-row harvesting combine of this embodiment, when each has a pulling path on both the left and right sides of the pulling device in the middle in the left-right direction, the grains of adjacent strips are separated by the weed bodies in front of the lower part of the pulling device, and the left and right Introduced into each elicitation path. However, in the case where the culm is a long culm etc., as shown in FIG. 20, it is cut by the cutting blade device 9 while crossing over the pulling device without being entangled and separated by the tip of the adjacent culm, May be transported backwards. At this time, if the upper end of the pulling device and the cover 15 are in contact with each other, the cross portion straddling the pulling device is caught by the contact portion and cannot be passed rearward and is clogged. Moreover, even if the entanglement of the tip is forcibly solved by the conveying force of the cereal, the grain of the tip may be shattered by the squeezing action between the tips or the squeezing action by the corners of the cover 15 and the raising cases 12 and 13. Inevitable. Therefore, when each of the left and right sides of the pulling device 8 in the left-right direction has pulling paths, as shown in FIGS. 21 to 23, there is at least a cereal passing space 15 s between the upper end of the pulling device 8 and the cover 15. It is preferable to have a structure that is secured, and by connecting the pulling paths on both the left and right sides with the culm passage space 15s, the croaker has a structure that passes backward as it is even if the tip of the culm is crossed. Such a cereal pass space 15s may be formed in a structure that is formed regardless of the posture of the cover 15, but in this case, the position of the cover 15 becomes high and obstructs the front view. It is preferable to have a structure that is formed only when 15 is in an open posture.

  As shown in FIGS. 21 to 23, the auxiliary pulling lug 62 protrudes forward at the front position of the pulling device 8 in order to perform pulling up effectively in the field state where the cereals are entangled in the lying state. There is a case where an auxiliary pulling device 60 that pulls and rotates while being divided into left and right with respect to the cereal grains that are entangled in a lying state may be attached. The auxiliary pulling device 60 includes an auxiliary pulling case 61, an endless auxiliary pulling chain that is wound around and driven by a transmission sprocket and a tensioning wheel (not shown), and is installed in the auxiliary pulling case 61. And auxiliary pull-up lugs 62 attached at predetermined intervals. The auxiliary pull-up lug 62 protrudes forward from the auxiliary pull-up case 61 when it moves upward and obliquely upward along with the auxiliary pull-up chain, and raises the grain while dividing it into left and right. In the work in such a situation, it is preferable to provide the above-described cover 15 because grains and mud easily jump to the driver's seat 5 side. However, the auxiliary pulling device 60 is not separated without being entangled with the tips of adjacent grains. In addition, a phenomenon of being conveyed while crossing over the pulling device 8 is likely to occur. Therefore, in particular, when such an auxiliary pulling device 60 is provided, as shown in the drawing, the above-described cereal pass space 15s is provided above the working range of the auxiliary pulling lug 62 of the auxiliary pulling device 60, and the auxiliary pulling device 60 and It is preferable to configure the cereal erupted by the pulling device 8 so that it passes rearward as it is even when the tip portion is crossed.

  In the present embodiment, the cutting side covers 18 and 18 disposed on the left and right sides of each pulling device 8 are divided into an upper side cover 18a and a lower side cover 18b, and the upper side cover 18a is formed on the lower side cover 18b. On the other hand, it is superposed on the upper side surface and the outer side surface and integrated with the cover 15 so as to be swingable up and down together with the cover 15. The cutting side covers 18 and 18 and the upper side cover 18a may be formed as a single cover member. Thereby, the upper side cover 18a can be used as a handle, and the cover 15 can be swung together with the upper side cover 18a. Therefore, the posture changing operation of the cover 15 can be easily performed without providing a dedicated handle. It becomes like this. Further, in this embodiment, since the front raising case 12 and the lower side cover 18b cannot be removed unless the cover 15 and the upper side cover 18a are rotated upward, the cover 15 and the upper side cover 18a It has a structure that functions as a lock mechanism that locks the front elevating case 12 and the lower side cover 18b by closing downward. Therefore, the lower side cover 18b superposed on the lower part of the upper side cover 18a can be easily attached and detached, and maintenance of the reaping device is easy.

  As shown in FIGS. 16 to 19, a handle 15 </ b> H for swinging and opening the cover 15 can be attached to the cover 15. The handle 15H preferably protrudes upward from a portion near the driver seat 5 of the cover 15, for example, a portion in front of the driver seat 5, so that the cover 15 can be swung from the driver seat 5.

  The cover 15 in the present embodiment is provided with an adjusting body 50 that can expand the front and rear direction cover range. Since this adjusting body 50 can adjust not only the inclination posture of the cover 15 in the front-rear direction but also the front-rear cover range of the cover 15, the operator can scatter the grains and the like depending on the state of the field and the length of the culm. Accordingly, the cover 15 can be adjusted to an appropriate position and posture while comparatively considering the forward visibility and the prevention of scattering of grains and the like according to the posture and body shape of the operator.

  For example, when grains etc. scatter to the driver's seat 5 side, as shown in FIG. 29 (b) and FIG. 23, the attitude of the cover 15 is changed to an open attitude where the crossing angle with respect to the direction of grains etc. is perpendicular or close to it. When the change range is further widened, the cover range is expanded forward by the adjusting body 50 as shown in FIGS. 29 (c) and 8 as necessary. The front view can be secured as much as possible while effectively blocking. On the other hand, when there is no scattering of grains or the like, or when scattering to the driver's seat 5 side is small, the posture of the cover 15 is parallel to the scattering direction of the grains etc. as shown in FIGS. Alternatively, by changing to a closed posture close to that, and further adjusting the adjusting body 50 to the non-enlarged state as necessary, it is possible to make the front view more important. Furthermore, in order to make the cover range about the middle of these, as shown in FIG. 29 (d) and FIG. 25, the posture of the cover 15 is changed so that it is parallel to or close to the scattering direction of grains and the like. The adjustment body 50 may be in a state of being enlarged forward. Thus, the adjustment of the posture of the cover 15 and the cover range can be arbitrarily changed by the operator, and is not limited to such an adjustment form.

  The adjuster 50 is preferably formed of a transparent or translucent plastic plate such as polycarbonate to ensure the visibility through the adjuster 50, but can also be formed of a metal plate. The shape of the adjusting body 50 can be determined as appropriate. In addition to the rectangular shape as shown in the illustrated example, the shape of the front end edge can be an arc shape.

  The adjusting body 50 of the present embodiment expands the front cover range of the cover 15, but may have a structure that expands the cover range of the rear side or both front and rear sides. Although the amount of expansion of the cover range in the adjusting body 50 can be determined as appropriate, as shown in FIG. 5, the rear end of the front raising case 12 is rearward of the bent position 12c in the posture change state in which the front end of the cover 15 is located in the foremost position. It is preferable that the front end of the adjusting body 50 be positioned forward of the bent position 12c of the front pulling case 12 by expanding the cover range of the adjusting body 50 forward. As a result, if the front end of the adjusting body 50 is positioned behind the bent position 12c of the front raising case 12, the operator can directly view the weeding position while sitting on the driver's seat 5, and can easily check the raising state of the weeding. It is possible to increase the efficiency of the cutting work, and the front end of the adjustment body 50 is effectively positioned forward of the bent position 12c on the front surface of the front pulling case 12 as necessary. It is also possible to prevent scattering of grains and the like.

  In the multi-row cutting combine of the present embodiment, the driver's seat 5 is provided on the right side (or the left side) of the traveling vehicle body 1, and the pulling device 8 is also provided in front of the driver's seat 5. In such a multi-row cutting combine, the cover 15 extends so as to extend over the pulling devices 8 at both ends, and the adjustment body 50 extends in the left-right direction so as to cover at least the left-right range corresponding to the driver's seat 5. Is preferred. In this case, as shown in FIGS. 1 to 12, if the adjustment body 50 is provided over substantially the entire left and right direction of the cover 15, the effect of preventing the scattering of rice husks and the like is excellent, but as shown in FIGS. 14 and 15. It is also possible to provide an adjustment body 50 only at the front position of the driver's seat 5 so that it is inexpensive and has a superior front view. In any case, the operator can adjust the driver 50 from the driver's seat 5 by adjusting his / her hand so that more accurate adjustment can be made, and grains such as grains that are scattered upward and backward due to the occurrence of the cereal can be obtained. Of these, at least the driver heading toward the driver's seat 5 can be effectively blocked.

  In particular, when the adjustment body 50 is directly operated by hand, the cover 15 and the adjustment body 50 extend to the left end of the left end pulling device 8 or the right end of the right end pulling device 8 (particularly on the driver's seat 5 side). It is preferable. As shown in FIG. 13, when the driver's seat 5 is positioned on the right side of the traveling vehicle body and the pulling device 8 extends to the right of the driver's seat 5, scattering of rice husks and the like from the protruding portion is also prevented. Therefore, it is preferable to extend the cover 15 and the adjustment body 50 to the right side of the driver's seat 5. Similarly, when the driver's seat 5 is on the left side and the extension of the pulling device 8 is on the left side, the cover 15 and the adjustment body 50 are preferably extended to the left side of the driver's seat 5.

  The enlargement adjustment mechanism of the adjustment body 50 can be determined as appropriate, and a mechanism (not shown) that slides along the enlargement direction can also be adopted. However, the adjustment body 50 of the present embodiment is shown in FIGS. As described above, the base end portion is pivotally supported on the cover 15 by the adjusting body support shaft 51 provided in the front end portion of the cover 15 along the left-right direction, and the distal end portion rotates around the adjusting body support shaft 51 as a rotation fulcrum. By moving, the cover range in the front-rear direction of the cover 15 is expanded. In this case, the adjustment of the cover range by the adjustment body 50 can be changed by rotating the adjustment body 50 around the adjustment body support shaft 51 with respect to the cover 15, so that the change operation is not only simplified with one touch, Since the angle of the adjusting body 50 can also be adjusted, it is possible to expand the cover range so as not to obstruct the front view. Further, when the cover 15 is swung upward, it is possible to easily attach and detach the front raising case 12 while preventing the grain and mud from scattering to the operator side. There is also an advantage that maintenance can be easily performed.

  Although the rotation mechanism of the adjusting body 50 can also be determined as appropriate, in this embodiment, the adjusting body 50 is provided with a pair of holding portions 52 and 53 for elastically holding the adjusting body support shaft 51, and one holding portion. 52 is constituted by a flat plate body (spring material) having a certain degree of elasticity, and the other sandwiching portion 53 is constituted by a plate body having an arcuate receiving groove 53d into which the adjusting body support shaft 51 is fitted. As a result, the adjustment body 50 can be reliably supported with a simple and inexpensive configuration, and stepless rotation is possible. Further, when the adjusting body 50 is rotated, rust and dust between the contact surfaces can be quickly removed by friction between the holding portions 52 and 53 and the adjusting body support shaft 51, and the cover is always rotated smoothly. Will be able to.

  Further, the pair of clamping portions 52 and 53 of this embodiment have screw insertion holes that penetrate in the clamping direction, and nuts 54n are inserted through the screw insertion holes from the one side to the other side by adjusting bolts 54b. Since the one clamping part 52 is elastically pressed against the other clamping part 53 by screwing and tightening to the other clamping part 53, it is easy to turn the adjusting body 50 with only the tightening torque of the adjusting bolt 54b. Can be adjusted. Therefore, it is preferable to provide such a rotational load adjusting means.

  Furthermore, it is preferable that the adjusting body support shafts 51 are provided at a plurality of positions at intervals in the left-right direction of the cover 15 because the support of the cover 15 is stabilized. In this case, the adjusting body 50 is provided with the above-described rotational load adjusting means. If the turning load of the adjusting body 50 on the adjusting body support shaft 51 far from the driver seat 5 is made weaker than the turning load of the adjusting body 50 on the adjusting body support shaft 51 on the driver seat 5 side, the driver seat 5 side Therefore, the adjustment body 50 can be easily rotated.

  In this embodiment, the adjusting body support shaft 51 is provided on the cover 15 and the sandwiching portions 52 and 53 are provided on the adjusting body 50. On the contrary, the sandwiching portions 52 and 53 are provided on the cover 15 and the adjusting body support shaft 51 is provided. The adjustment body 50 may be provided.

  On the other hand, the illustrated embodiment is an application example to a non-cabinet type in which the driver's seat 5 is not surrounded by a window, but the present invention can also be applied to a cabin type having a driver's cab surrounded by a window. Even in this case, there is an advantage that the water droplets on the window and dirt due to mud can be prevented.
