  In the above prior art, the waste straw discharged from the terminal end of the waste straw transporter is once dropped onto a horizontal belt conveyor through a vertical drop path below the waste straw and the received waste straw is belted. It is the structure which forcibly feeds toward the roll forming chamber of a roll baler with a conveyor.

  In the middle of the vertical discharge path of the waste drainer, there is a dust discharge port for dust that is discharged from the dust discharge fan and a waste discharge port that is discharged from the end of the Strollac. The dust blower and the tang wind from the dust discharge outlet impede the fall of the waste straw, and the feed direction is extremely changed from the vertical direction to the horizontal direction. There is a problem that clogging of the waste straw occurs.

  The present invention has taken the following technical means in order to solve the above-described problems. That is, this invention of Claim 1 is arrange | positioned behind the conveyance termination | terminus part and the threshing part of the waste straw carrier apparatus (8) which carries out the waste straw processed by the threshing part (4), and receives a waste straw. Between the roll baler (10) to be compressed and packed, the waste wall falling from the end of the waste wall transporter is routed along the dust discharge path (F) for discharging the dust from the dust discharge fan (15) downward and downward, and A discharge wall guide means (40) for guiding toward the discharge wall receiving part (31) of the roll baler is provided.

  The waste straw after the threshing process that falls from the conveyance end portion of the waste straw transporter (8) is received by the waste straw guide means (40) along the dust passage (F) of the dust fan (15), While being guided toward the roll, it is dropped and supplied straight to the receiving part (31) of the roll baler.

  Since the waste straw guide means (40) is along the dust passage (F), the guide fall of the waste straw is energized by the dust wind, and the waste straw is vigorously guided and supplied toward the roll forming chamber. become.

  According to a second aspect of the present invention, in the first aspect, the exhaust wall guide means (40) is constituted by a plate body and covers the upper side of the dust path (F) (a) and the dust path (F). It is characterized in that it can be switched to a state (b) that receives the lower part.

  At the time of roll forming by the roll baler, the exhaust wall guide plate (40) is switched to a state under the dust path so that the exhaust wall is smoothly guided and supplied into the roll baler by the action of the dust exhaust air. Then, the exhaust wall guide plate (40) is switched to a state covering the upper part of the dust path so that the dust exhaust air is prevented from entering the roll baler so that the bundling action is performed satisfactorily.

  In short, according to the first aspect of the present invention, since the discharge wall guide means from the discharge wall conveying terminal part to the roll baler is along the dust discharge path in which the dust discharge direction is obliquely downward rearward, Thus, the exhaust air can be smoothly guided and supplied into the roll baler.

  According to the second aspect of the present invention, while the effects of the first aspect of the present invention are exerted, the dust discharge wind is switched by switching the exhaust guide plate to a state covering the upper side of the dust discharge path when the rolls are bound. Since it can block | block so that it may not enter into a roll baler, when a wind enters into a roll baler, the malfunction that a net | network does not go down and cannot be bound can be prevented.

The swing sorting device 11 is configured to receive the processed product after the threshing process from the handling room and sort the sieve while swinging and transferring, and from the upper side in the sorting direction, the transfer shelf 16, the chaff sheave 17, the strut. Arranged in the order of the racks 18 and provided with a grain sheave 19 disposed below the chaff sheave 17, it leaks from the handling chamber by the combined action of the sorting wind and swinging by the tang 12 and the cross flow fan 15. In this configuration, the screened material is received while being swung and transferred.

  The dust exhaust fan (cross flow fan) 15 has a dust exhaust air from the dust exhaust port (air exhaust port) 20 on the dust exhaust guide plate 21 inclined downward from the lower edge of the dust exhaust port. The dust discharge path F is configured so as to discharge along.

  The roll baler unit 10 includes a front molding chamber 25 fixed to the machine body and a rear portion pivotally connected to the rear upper end of the front molding chamber 25 by an expansion / contraction operation of an opening / closing cylinder mechanism (not shown). When the rear molding chamber 26 is closed, a single molding chamber is formed by both the front and rear molding chambers 25 and 26. In a state where the rear molding chamber 26 is closed, an endless chain 27 formed by connecting a large number of molding pipes at a predetermined interval is a guide sprocket portion that is disposed in the middle with the sprocket portions 28 and 29 at the start and end as folding portions. The exhaust wall receiving part 31 formed between the sprocket parts 28 and 29 is configured to rotate while passing through 30, 30,... It is installed. With the above configuration, in the packing space 35 in the molding chambers 25 and 26, the waste straw introduced from the waste straw receiving portion 31 is gradually increased in outer shape while being rotated in the circumferential direction by the molding pipe of the endless chain 27. When the packaging space 35 is filled with the waste straw, the waste straw formed in a roll shape is compressed to form a roll bale.

  The net 36 is fed out from the upper part of the front molding chamber 25. When it is detected that the exhaust bran is compressed to a predetermined pressure, the net is fed out and wound around the outer periphery of the roll bale.

  The roll baler waste discharger receiving portion 31 is positioned corresponding to the dust discharge path F of the dust discharge fan 15, and the dust exhaust air is blown into the molding chamber from the waste blower reception portion 31 together with the dust. The dust wind that has entered the roll baler passes through the wind duct chamber 38 while swirling in the molding chamber, and then comes out of the machine.

  Between the conveyance end part of the waste wall conveying device 8 and the waste wall receiving part 31 of the roll baler 10, the waste wall falling from the waste wall conveying terminal is received and guided toward the waste wall receiving part 31 of the roll baler. Wall guide means (drain wall guide) 40 is provided. The drainer guide 40 is along the dust path F by the dust fan 15, and the drainer is guided and dropped together with the dust.
