A second lifting cylinder 48 is provided for lifting the second thing collected in the second helix 47 to the second processing chamber 41.

  The configuration of the swing sorting shelf 38 will be described. The swing sorting shelf 38 includes, in order from the start side in the sorting and feeding direction, a transfer shelf 49 for transferring the fallen cereals backward, a grain sheave 38a for sorting the cereals, a chaff sheave 38b for sorting the second thing, and dust. It is composed of a Strollac 38c that loosens and collects the scorpion grains and transports and discharges dust. Below the Strollac 38c is constituted by a second shelf tip 47a for guiding the second item into the second spiral 47, and the dust removal processing cylinder 35 extends to the vicinity of the terminal end of the second shelf tip 47a. It is the composition which has taken out. The suction fan 51 is for discharging light dust in the sorting chamber 50 to the outside of the machine, and is provided at a position facing the dust removal processing cylinder 35 with respect to the handling cylinder 31. Reference numeral 52 denotes a crankshaft that drives the swing sorting shelf 38 to swing.

  The cereals conveyed from the reaping device 3 are taken over by the start end of the feed chain 15 of the threshing device 9, and the cereals inherited by the feed chain 15 are transported rearward while It is threshed by the handling net 30. A part of the threshed threshing falls on the swing sorting shelf 38 and is sorted by the swinging action of the swing sorting shelf 38 and the wind sorting action from the Kara 43 and is taken into the spiral 46 first. Accordingly, the grain taken into the first spiral 46 is configured to be temporarily stored in the glen tank 16. After the threshing, the waste is handed over from the terminal end of the feed chain 15 to the start end of the waste chain 18 and then sent to the cutter 19 where it is cut and released onto the lower field. It has become.

  The remaining threshing in the handling chamber 31 is conveyed rearward, and a part of the threshing is taken into the second processing chamber 41 along the way. The threshing taken into the second processing chamber 41 is threshed by the interaction between the second processing cylinder 39 and the second processing cylinder receiving rod 40 (particularly, branch branch) The particles are processed) and fall onto the lower swing sorting shelf 38. The handling cylinder 31, the second processing cylinder 39, and the dust removal processing cylinder 35 are configured to rotate clockwise in a situation (a front view of the threshing device 9) when the lower side is viewed from the upper side in the sorting wind feed direction. Therefore, it is necessary to fix the direction of the processing teeth 39a of the second processing cylinder 39 in such a direction as to send the cereals in the upper direction of the sorting wind feed direction.

  That is, the processing teeth 39a have an action of conveying the workpiece to the upper side in the sorting air feed direction, and further have an action of processing the workpiece. That is, the processing tooth 39a is a part of a spiral, and is configured to process the object to be processed by the interaction between the circumferential tip portion thereof and the second processing cylinder receiving rod 40. The blades 39b provided at the conveying terminal end of the second processing cylinder 39 forcibly send the workpiece to the swing sorting shelf 38.

  The dust removal processing teeth 35a of the dust removal processing cylinder 35 need to be fixed in such a direction as to send the cereal from the rear part of the handling chamber 33 in the lower direction of the sorting wind feed direction. In the present embodiment, the dust removal treatment teeth 35 a have a spiral shape that is wound around the outer peripheral surface of the dust removal treatment cylinder 35.

  However, in this embodiment, since the dust disposal mesh 34 is rough (lattice), some short sawdust falls on the swing sorting shelf 38, and long sawdust that has not fallen is dust. It is transported to the end portion of the processing chamber 37 and is forcibly discharged onto the strola rack 38 c by the blade 35 b at the end portion of the dust removal processing cylinder 35. While the object to be processed is thus transported in the dust processing chamber 37, the dust processing cylinder 35, the processing teeth 35 c provided with the dust processing cylinder 35 and the dust processing net 34 are provided. Through the interaction, the threshing is further loosened, the threshing is loosened and the grains (so-called scorpion grains) mixed in are taken out and fall on the lower swing sorting shelf 38, and It is configured to be collected into the spiral 47.

  As described above, the remaining cereal that has not fallen on the swing sorting shelf 38 due to cerealing in the processing chamber 33 and that has not been taken into the second processing chamber 41 is conveyed to the end of the processing chamber 33. It will be done. The threshing that has been transported to the end of the handling chamber 33 is taken into the dust removal processing chamber 37, and the taken-in threshing is transported to the lower side in the sorting wind feed direction. Of the threshing that has been transported to the end of the handling chamber 33, the threshing that has not been taken into the dust disposal chamber 37 falls on the swinging sorting shelf 38 below.

  When the cereal is sent from the end portion in the handling chamber 33 into the dust removal processing chamber 37, the dust removal treatment cylinder is also provided at the takeover portion from the handling chamber 33 to the dust removal treatment chamber 37 so that the cereal removal is not clogged. Spiral-shaped dust removal processing teeth 35a are provided on the outer periphery of 35, and the take-off portion is prevented from being clogged by the feeding action of the dust removal processing teeth 35a.

  In spite of the swinging action of the swinging sorting shelf 38 and the action of the sorting wind from the red pepper 43, the remaining grains that are not taken into the spiral 46 are further collected together with other dusts. It is sent to the rear and taken into the second spiral 47. The second product taken into the second spiral 47 is reduced to the lower side in the sorting air feed direction of the second processing chamber 41 by the second lifting cylinder 48 and merged with the cereal from the handling chamber 33. Then, while being transported to the upper side of the sorting wind feed direction, it is transported while being threshed by the interaction with the second processing barrel receiving rod 40, and is placed on the lower swing sorting shelf 38 by the blade 39b at the end portion. It is the composition that falls forcibly.

  Reference numeral 53 shown in FIGS. 4 and 5 denotes a dust feeding plate provided in the upper part of the second processing chamber 41. FIG. 6 shows the dust feeding plate 53 as viewed from the glen tank 16 side. FIG. 7 shows the relationship between the inclination angle of the dust feeding plate 53 and the inclination angle of the processing teeth 39 a provided in the second processing cylinder 39.

  As described above, the second object in the second processing chamber 41 is sent in the B direction (front side) by the feeding action of the processing tooth 39a while being processed by the processing tooth 39a. For this reason, an angle C is formed in the processing tooth 39a. On the other hand, although the angle D is formed also in the dust sending plate 53, the angle D of the dust sending plate 53 is an angle that gives resistance in the feeding direction in the arrow B direction. Accordingly, when the second object that is about to flow in the direction of the arrow B comes into contact with the dust feeding plate 53, resistance is generated, and the second object can be processed by this resistance. Moreover, since the time for which the second product is present in the second processing chamber 41 becomes longer, the processing action by the processing teeth 39a is increased, and the branch infarction removing operation is efficiently performed. In particular, the second processing drum 39 can be configured to be short, and a compact threshing apparatus can be provided.

  When the angle C of the processing tooth 39a and the angle D of the dust feeding plate 53 are compared, the configuration is such that C> D. As a result, it is possible to prevent excessive resistance from being applied by the dust sending plate 53 to the feeding of the second object in the direction of the arrow B, thereby preventing clogging and the like from occurring.

  Further, the angle D of the dust feeding plate 53 is configured to be variable. That is, in the case of a wet material or the like, the angle D is made smaller than the angle C, so that excessive resistance is prevented and clogging or the like is prevented from occurring. Further, even when not a wet material, even when a large amount of an object to be processed is thrown into the threshing device 9, the angle D is made smaller than the angle C to prevent clogging and the like. Like that.

  Moreover, when there are few to-be-processed objects thrown in into the threshing apparatus 9, the angle D of the dust sending board 53 is changed, and many resistance is given to a 2nd thing. As a result, since the processing action of the second item is improved, the sorting performance of the first item is improved. In particular, in the case of a high yield state or a large amount of sawdust, the amount of the second product increases and the second product may overflow, but by reducing the resistance, It is possible to prevent clogging of the number and to suppress the generation of damaged grains.

  Reference numeral 54 shown in FIG. 6 denotes a tension spring, which always urges the dust feeding plate 53 to the resistance side. When the number of second objects in the second processing chamber 41 increases, the urging force of the tension spring 54 is overcome, and the dust feeding plate 53 is inclined in the second material feeding direction.

Thereby, in the second processing chamber 41, it is possible to prevent a problem that the second thing is stagnated and clogged.
Reference numeral 55 shown in FIG. 6 denotes a connecting plate that connects a plurality of dust feeding plates 53. In the connecting plate 55, a cable 56 is connected, and a lever 57 is provided at the other end of the cable 56. And it is comprised by operating this lever 57 so that the inclination-angle D of the dust sending plate 53 can be changed. Further, the lever 57 is provided in the operation unit 13. Thereby, even during work, the inclination angle of the dust sending plate 53 can be easily changed.

  58 shown in FIG. 5 is a second sensor for measuring the amount of the second product, and is provided at the outlet portion of the second lifting cylinder 48. Then, the inclination angle D of the dust feeding plate 53 is automatically changed according to the measured value of the second sensor 58. Specifically, when the amount of the second object increases, the inclination angle D of the dust feeding plate 53 is changed to the feeding direction.

Further, when the amount of the second object is small, the inclination angle D of the dust sending plate 53 is inclined in a direction in which resistance is applied to the feeding direction of the second object.
In this case, a motor 59 for automatically moving the dust feeding plate 53 is provided on the front side of the threshing device, and a plate 61 is provided on the output shaft 60 of the motor 59. In this configuration, cables are connected. That is, when the output shaft 60 of the motor 59 rotates in the forward and reverse directions, the cable 56 is pushed and pulled through the plate 61, the dust feeding plate 53 is rotated, and the inclination angle D is increased. The configuration is changed.

  As described above, the inclination angle D of the dust sending plate 53 is configured to be manually adjustable and automatically adjustable. However, basically, manual is given priority. Therefore, the work efficiency is improved.

  In FIG. 8, the adjustment step of the lever 57 is shown. In other words, the vehicle speed is adjusted in two stages: low speed, standard speed, high speed, and wet material. Of course, there may be fewer or more than these five stages. FIG. 9 shows the relationship between the operation position of the lever 57 and the inclination angle of the dust sending plate 53. In the low-speed two stages, the angle acts to cause resistance against the feeding direction of the second object. And in standard vehicle speed, high speed, and a wet material, it is comprised so that it may incline in the feed direction of a 2nd thing in order.

  Even when the inclination angle D of the dust sending plate 53 is changed according to the measured value of the second sensor 58, the angle region when the lever 57 is manually operated to change the inclination angle D of the dust sending plate 53. Same as.

  As shown in FIGS. 6 and 7, a fixed dust sending plate 62 is provided in the dust removal processing chamber 37. In this case, the dust discharge direction in the dust treatment chamber 37 (airframe) An inclination angle is given to the rear. Thereby, the feeding action of the dust is improved, and clogging and the like can be prevented.

  Further, the inclination angle E of the dust sending plate 62 in the dust removal processing chamber 37 is configured to be larger than the inclination angle D of the dust sending plate 53 in the second processing chamber 41 described above. As a result, the feeding action of the dust in the dust treatment chamber 37 is improved.
