A chain disengagement prevention plate (inner member) 87 for covering the left side is provided. The upper edge of the chain detachment prevention plate 87 is formed so as to substantially follow the conveying path of the cereal. Most of the chain detachment prevention plate 87 is covered with the threshing side lower cover 61 on the left side, but the upper end portion of the chain detachment prevention plate 87 is exposed without being covered. And in this exposed part, the base part of the rod-shaped stock base guide body 90 is attached to the said chain disengagement prevention board 87. FIG.

  As shown in FIG. 5, the stock guide 90 is configured by bending a round bar-like elongated member, and includes an attachment portion 90 a, a first guide portion 90 b, and a second guide portion 90 c. Yes.

  The attachment portion 90a is fixed to the chain detachment prevention plate 87 by welding in a state of being directed parallel to the upper edge portion of the chain detachment prevention plate 87. The attachment portion 90 a is arranged in a direction parallel to the direction in which the cereal grains 71 are conveyed by the feed chain 81.

  The first guide portion 90b is disposed so as to continuously extend rearward from the rear end of the attachment portion 90a. The first guide portion 90b has substantially the same orientation as the attachment portion 90a as shown in FIG. 4 in a side view, but moves away from the body 11 to the left as it goes rearward as shown in FIG. 5 in a plan view. It is arranged at an angle.

  The second guide part 90c is arranged so as to extend further rearward from the rear end of the first guide part 90b. The second guide portion 90c has substantially the same orientation as the attachment portion 90a and the first guide portion 90b as shown in FIG. 4 in a side view, and substantially the same orientation as the attachment portion 90a in a plan view as shown in FIG. It is arranged to become.

  Here, the thick broken-line arrow in FIG. 4 indicates the direction in which the cereal 71 is conveyed along the cereal conveyance path 70. As shown in FIG. 4, the cereal conveying path 70 includes an upper threshing side upper cover 60, a shutter member 64 and a sewage upper cover 63, a lower threshing side lower cover 61 and a sewage lower cover 62, Are formed elongated in the front-rear direction.

  On the other hand, the stock guide body 90 extends along the lower edge of the cereal conveying path 70 in a side view from the midway in the longitudinal direction of the cereal conveying path 70 (near the end of the feed chain 81 on the feed terminal side). Are arranged as follows. Further, as shown in FIG. 5, the first guide portion 90 b of the stock guide 90 is disposed so as to be slightly away from the aircraft 11 as it goes to the rear of the aircraft 11 in a plan view.

  In this configuration, when the culm 71 is cut and threshed by the threshing device 14, the cereal 71 is transported by the feed chain 81 in a state where the stock portion protrudes to the left from the cereal transporting passage 70. Then, the culm 71 that has been threshed by the threshing device 14 is inherited by the waste transporting device 50 in the vicinity of the end of the feed chain 81 on the feed end side. The waste conveying device 50 takes the grain straw 71 into the body, in other words, pulls the grain straw 71 into the back of the grain straw passage 70 (on the right side of the body) and further conveys it backward to the waste cutter device. 53.

  By the way, various kinds of grains such as rice and wheat can be considered as the grains 71 to be harvested by the combine 10, but when the grains 71 to be harvested are long, the stock of the grains 71 comes out from the grains transport passage 70. The length also increases.

  In this respect, in this embodiment, as shown in FIG. 6, in the rear part from the feed end side of the feed chain 81 (the feed start end side of the waste transporting device 50), from the grain transporting passage 70 to the side of the body 11. The stock base portion 71 f of the grain ridge 71 that protrudes long is supported from below by the stock guide 90. Therefore, in the case where the long culm 71 is harvested and harvested, even if the cereal 71 is weak, the cereal 71 is supported by the stock guide 90 so that the cereal 71 does not hang down. Can be drawn into the back of the cereal conveyance passage 70 by the sewage conveyance device 50. As a result, it is possible to prevent the drooping of the culm 71 from becoming a resistance against the uptake of the culm 71 by the squeezing / conveying device 50, so that smooth transportation by the scouring / conveying device 50 can be realized. Moreover, since the resistance by the drooping of the grain basket 71 can be prevented as described above, the attitude of the grain basket 71 conveyed by the waste conveying apparatus 50 is stabilized, and the attitude of the grain basket 71 put into the waste cutter apparatus 53 is stabilized. Can be arranged. As a result, processing such as cutting of the grain candy 71 in the waste cutter apparatus 53 is facilitated, and work efficiency can be improved.

  Here, the stock guide body 90 is a portion of the grain culm transport passage 70 where the waste transporting device 50 takes in the grain stalk 71 (in other words, the sag of the grain stalk 71 affects the transport of the corn straw 71). Only the easy part) is configured to support the grain 71 from below. In other words, in the portion where the grain basket 71 is substantially conveyed by the feed chain 81, the stock portion 71f of the grain basket 71 is not supported. Therefore, the stock guide 90 can be realized by a short rod-like member having one end fixed to the chain disengagement prevention plate 87 as shown in the present embodiment, for example. Thereby, simplification and weight reduction of a structure can be implement | achieved easily.

  Further, as shown in FIG. 4, the stock base guide body 90 is disposed so as to substantially coincide with the lower edge of the cereal conveyance passage 70 in a side view. Accordingly, since the culm 71 (stock base portion 71f) coming out of the corn straw transport passage 70 can be supported substantially horizontally (with almost no bending or sagging in the corn grain 71) by the stock base guide body 90. Further, the posture of the culm 71 conveyed to the rejecting cutter device 53 can be further stabilized.

  Furthermore, the 1st guide part 90b which the stock origin guide body 90 has is inclined so that it may become the left side as it goes back in planar view. Due to this inclination, the first guide portion 90b acts to gradually lift and support the stock portion 71f of the cereal bowl 71 conveyed toward the rear. Therefore, the resistance in the part in which the waste conveying apparatus 50 takes in the grain 71 can be further reduced, and smooth conveyance can be realized.

  Moreover, the 2nd guide part 90c (part projected to the left most) of the stock origin guide body 90 is arrange | positioned in the left-right direction inner side of the body 11 rather than the left end of the indicator lamp 66, as shown in FIG. Thereby, since the stock guide body 90 can realize a compact configuration in which the left and right width (outermost side) of the machine body 11 is not widened, for example, when the combine 10 is loaded on a truck for transportation, the stock guide body 90 There is no need to remove or fold.

  Next, the relationship between the arrangement of the stock guide 90 and the maintainability of the machine 11 such as the feed chain 81 will be described with reference to FIGS. FIG. 7 is a right side view showing a state where the threshing side lower cover 61 is removed. FIG. 8 is a plan view showing a state where the threshing side lower cover 61 is removed. FIG. 9 is a plan view showing a state in which the feed chain 81 is rotated to the side.

  First, attachment / detachment of the threshing side lower cover 61 will be described. As shown in FIGS. 7 and 8, the threshing side lower cover 61 is detachably attached to the body 11. In addition, about the structure which can attach or detach a cover, arbitrary things, such as a well-known hook mechanism, can be used, for example.

  As described above, most of the chain detachment prevention plate 87 is covered with the threshing side lower cover 61, but the stock guide 90 is not covered with the threshing side lower cover 61. It is attached to the upper end of the. Therefore, as shown in FIG. 4, the arrangement | positioning which the stock origin guide body 90 and the threshing side lower cover 61 do not overlap by a side view is implement | achieved.

  Further, the stock source guide body 90 passes above the threshing side lower cover 61 and extends to the outside of the machine body 11 more than the threshing side lower cover 61. Therefore, the threshing side lower cover 61 can be easily attached to and detached from the machine body 11 as shown in FIG. 7 and FIG. 8 without removing the stock guide body 90.

  Next, the opening of the feed chain 81 will be described. As shown in FIG. 9, with the threshing side lower cover 61 removed, the feed chain 81 can be rotated about the vertical axis by a rotation mechanism (not shown) provided in the vicinity of the drive pulley 86. It is configured as follows. The feed chain 81 is configured such that the front side opens to the left of the body 11.

  The chain detachment prevention plate 87 and the stockholder guide body 90 rotate with the rotation of the feed chain 81. Here, as shown in FIG. 4, the first guide portion 90 b and the second guide portion 90 c included in the stock guide 90 are positioned so as to be included in the opening region of the cereal conveyance passage 70 in a side view. Therefore, as shown in FIG. 9, the stock guide 90 fixed to the chain disengagement prevention plate 87 enters the cereal conveyance passage 70 as the feed chain 81 rotates. At this time, the stock guide 90 prevents the feed chain 81 from rotating by avoiding the stock cutter body 53 and the shutter member 64 in the vertical direction. Thus, since the stock guide 90 does not interfere with other members when the feed chain 81 is opened, the maintenance work of the feed chain 81 is facilitated.

The feed chain 81 conveys the culm 71 threshed by the threshing device 14 along the elongated culm transporting passage 70. The waste transporting device 50 inherits the rice cake 71 from the feed chain 81 and transports it to the waste cutter device 53 so as to take the rice cake 71 into the grain transporting passage 70. The stock source guide body 90 supports the portion where the culm 71 protrudes outward from the culm transporting passage 70 only in the portion where the waste transporting device 50 takes in the culm 71.

  As a result, the stock base portion 71f of the stalk 71 protruding outside the stalk transporting passage 70 is hung by the compact stock guide 90 disposed in the vicinity of the portion where the waste transporting device 50 takes in the stalk 71. The posture of the culm 71 that is transported from the waste transporting device 50 to the waste cutter device 53 can be made less disturbed. As a result, it is possible to realize the combine 10 capable of satisfactory processing in the waste cutter apparatus 53 at a low cost.

  Moreover, in the combine 10 of this embodiment, the stock origin guide body 90 is arrange | positioned so that the grain straw 71 can be supported horizontally.
