To 38.
[0013]
The straw scrap guide plate 7 is constituted by these guide plates 44 and 37. The guide plate 44 is the same as the front end portion of the feed chain 4 or protrudes to the front side of the feed chain 4 so that straw waste guided forward is not wound on the start end portion of the adjacent feed chain 4. . Further, the guide plate 44 on the feed chain 4 side may be extended to the lower side of the sub-chain 6 so that the guide plate 44 is integrated. In this case, the guide plate 44 is independent from the cereal supply funnel 5. The guide plate 44 on the sub-chain 6 side is formed in an L-shaped front section, but is formed in a bowl shape with a U-shaped section to form a straw waste guide plate 7, which is independent from the guide plate 37 on the feed chain 4 side. It may be configured as follows.
[0014]
The guide plate 37 covers the drive sprocket 31 of the feed chain 4 and the transmission belt 73 such as the carp 19 under the threshing device. Since the straw scrap guide passage 38 is configured outside the guide plate 37, the straw scrap guided by dropping does not wrap around the tension sprocket 33, the transmission belt 73, or the like.
[0015]
The cocoon 16 is provided along the end of the threshing cover 46 that opens and closes by turning up and down around the cover shaft 45 on the threshing chamber 2, and is fed by opening the threshing cover 46. It can be separated from the chain 4. 47 is a threshing net below the threshing chamber 2, which can be attached and detached by opening the transfer port cover 29.

A crankshaft 56 is mounted on the front end portion of the threshing frame and swings the swing sorting shelf 17. The drive sprocket 31 at the rear end of the feed chain 4 constitutes a coupling that can be fitted to and detached from the chain drive shaft 71 of the shaft mounted on the transmission case 70 fixed to the rear of the threshing frame, and this drive is achieved by opening and closing the transfer port cover 29. The sprocket 31 is fitted and removed, and the feed chain 4 can be transmitted by this fitting and removal. The input shaft 72 of the transmission case 70 is transmitted from the gear case 49 side through a belt 73 transmission mechanism.
[0018]
Mainly, in FIG. 6, the interval portion A between the transfer port cover 29 below the cereal transfer port 3 and the handling cylinder 1 is automatically adjusted. The lower end portion of the transfer port cover 29 has a function of a net pushing frame that supports the side edge of the threshing net 47. In some cases, the front and rear intermediate portions are deflected outward under the pressure of the threshing culm, and the spacing portion A becomes larger, which may reduce the threshing efficiency.
[0019]
In order to solve this problem, a strain gauge 57 that detects the interval A, a geared motor M that is driven by the detection of the strain gauge 57, and the motor M are rotated at one or several places in the front and rear intermediate portions. An interval adjusting device 59 composed of a bolt 58 and the like is provided. When the spacing portion A becomes large, the transfer port cover 29 is pressed toward the handling cylinder 1 with the bolts 58 and is automatically adjusted so that the spacing portion A becomes constant. Further, when the amount of the culm becomes small and the interval portion A becomes too narrow, the bolt 58 is reversely rotated, and the transfer port cover 29 is pulled back to keep the interval portion A constant.
[0020]
The feed chain rail 30 and the transfer port cover 29 are connected at an appropriate interval, but the brackets 60 and 61 are directly connected by bolts 74 at the front and rear portions of the transfer port cover 29, and several intermediate portions are provided. Are supported by the bolts 58 of the gap adjusting device 59.
[0021]
In FIG. 7, the difference from the above example is that the bolt 58 is directly manually adjusted instead of the automatic adjustment by the strain gauge 58 and the motor M.
Mainly in FIG. 8, in the configuration in which the transfer port cover 29 can be deployed integrally with the chain rail 41 of the feed chain 4, a gap portion B is formed between the lower end portion of the transfer port cover 29 and the threshing net 47, A C guide plate 62 is provided on the upper surface of the swing sorting shelf 17 at the lower end of the transfer port cover 29 so that the transfer port cover 29 can be easily opened and closed. Further, in the configuration in which the interval portion A is adjusted by moving the transfer port cover 29 as in the previous example, this movement is facilitated.
[0022]
9 and 10, the difference from the above example is that the handle 63 provided on the threshing feed port 3 part of the threshing cover 46 is also used as a stock transport guide rod for the threshing cereal, and the handle 63 The threshing cover 46 is not opened by simply pushing up the handle 63 by engaging the hook 64 with the hook pin 65 integral with the threshing frame side at the base of the threshing frame. The threshing cover 46 can be opened upward by pulling out toward the front against the hook and disengaging the hook 64 from the hook pin 65. As a result, the threshing cover 46 is not opened even if the handle 63 is simply pushed up when the amount of the culm is large. Reference numeral 67 denotes a slider at the base of the handle 63, which is slidably supported by a bracket 69 integrated with a pestle mounting frame 68 on the threshing cover 46 side.
