The rotation motor 14b of the rotation device 17 is attached to the reinforcing plate 17a fixed to the front side of the front side plate 14e of the discharge cylinder 14 by bolts, nuts, and the like within the outer shape portion of the grain transfer / discharge cylinder device 6. It is the structure provided. The rotating motor 14b is configured to support a motor gear 17b.

  As shown in FIGS. 1 and 2, the turning device 17 that turns the discharge cylinder 14 has a structure in which a turning fulcrum portion 16 d of the turning device 17 is formed in a double structure. A support shaft 16c is fixedly provided on the inner surface of the outer lid 13b of the transfer cylinder 13 for movement. The support plate 16a that supports the front support metal 16 provided inside the outer lid 13b is provided with an insertion hole for inserting the head of the support shaft 16c. The outer rotation support pipe 16e is inserted and supported on the outer periphery of the support shaft 16c, and the rotation fulcrum portion 16d has a double structure by the support shaft 16c and the outer rotation support pipe 16e. It is the formed structure.

  The rotation fulcrum 16d of the rotation device 17 that rotates and moves the discharge cylinder 14 that discharges the grain out of the machine through the grain outlet 14a has a double structure by the support shaft 16c and the outer rotation support pipe 16e. By forming and providing, the discharge cylinder 14 can be easily assembled and disassembled. Further, the rotational movement of the discharge cylinder 14 is smooth.

  An outer rotation support pipe 16e that is pivotally supported by the support shaft 16c of the rotation fulcrum 16d of the rotation device 17 is pivoted by a bearing 16f provided at the center of the front side plate 14e of the discharge cylinder 14. It is a supported structure. As shown in FIG. 1, the rotation fulcrum part 16d has two front and rear parts, the rear part is a bearing 16f part, and the front part is in the vicinity of the front end part of the support shaft 16c. This is a configuration provided by being fixedly supported at two locations with the front turning gear 17f provided at the tip.

  The rotating fulcrum portion 16d is provided in a double structure by being pivotally supported at two locations, ie, two front and rear bearing tools (bearing) 16f portions and a front rotating gear 17f portion of the outer rotation support pipe 16e. Therefore, the strength of the support shaft 16c can be increased by supporting and fixing the thinned support shaft 16c at the outer rotation support pipe 16e of the outer diameter portion and at two locations of the outer rotation support pipe 16e. It is.

  The outer peripheral portion of the outer rotation support pipe 16e is formed in an oval shape or a quadrangular shape, and an inner diameter portion is formed in the outer peripheral portion in the same shape as shown in FIGS. A rear rotation gear 17c is provided to be pivotally supported, and the rear rotation gear 17c and the motor gear 17b of the rotation motor 14b are engaged with each other. Friction brake plates 17d are pivotally supported on both front and rear sides of the rear rotation gear 17c, and brake press plates 17h are pivotally supported on both front and rear sides of the brake plates 17d. A plurality of disc springs 17e are pivotally provided on the front side of the brake presser plate 17h, and a front turning gear 17f is provided on the front side of the disc spring 17e. On the front side, the nut 16j is double screwed so that the brake pressure of the brake plate 17d can be adjusted, and the retaining is provided. Further, a nut 16h is screwed into the front end portion of the support shaft 16c on the front outer side of the outer rotation support pipe 16e to prevent it from coming off. The components 17c, 17d, 17e, 17f, 17h and the like that are pivotally supported on the outer rotation support pipe 16e rotate at the same time as the outer rotation support pipe 16e, but are not individually driven to rotate.

  As shown in FIG. 1, the outer rotation support pipe 16e of the rotation fulcrum 16d of the rotation fulcrum part 16d is supported by the outer rotation support pipe 16e of the rotation fulcrum 16d. In this configuration, the bearing tool (bearing) 16f is pivotally supported.

  In the configuration in which the outer rotation support pipe 16e of the rotation fulcrum portion 16d of the rotation device 17 is provided with a friction brake plate 17d pivotally supported, the outer rotation support pipe 16e of the rotation fulcrum portion 16d is a bearing. By using a bushing or the like instead of this bearing tool (bearing) 16f, it is necessary to apply grease when the temperature rises. The brake plate 17d may flow to the brake plate, and the brake may not be able to work. However, such a problem can be solved.

  As shown in FIGS. 1 and 2, a support metal 18a is attached to the upper portion of the front side plate 14e of the discharge cylinder 14, and a support shaft 18b of the support metal 18a has a large outer shape. This is a configuration in which the shaft 18c is rotatably supported, and the gear 18c and the front rotation gear 17f are engaged with each other. By the forward / reverse rotation drive of the rotation motor 14b, the motor gear 17b, the rear rotation gear 17c, the front rotation gear 17f, the gear 18c, etc. are driven forward / reverse rotation, and these various gears 17b, 17c, 17f, 18c, etc. From the rotational drive, the discharge cylinder 14 is controlled to rotate left or right, and after the grain outlet 14a is controlled to move upward, it is controlled to stop. Further, by the forward / reverse rotation driving of the rotation motor 14b, the discharge cylinder 14 is controlled to be restored to the original position, and the shed port 14a is controlled to be restored to the original lower position and then stopped. Moreover, it is the structure which can stop to arbitrary positions.

  The rotational position of the discharge cylinder 14 is detected. As shown in FIGS. 1 and 2, a potentiometer 15 described later in detail is rotated. Both the front rotation gear 17f that meshes with the gear 18c pivotally supported by the potentiometer 15 and the rear rotation gear 17c that meshes with the motor gear 17b of the rotation motor 14b are both the outer rotation support pipe 16e of the rotation device 17. It is the structure provided by pivotally supporting.

  A motor gear 17b of a rotation motor 14b for rotating a discharge cylinder 14 provided at a lower portion of a grain transfer discharge cylinder device 6 for discharging the grain out of the machine 6 and a rotation position of the discharge cylinder 14 are detected. The rear rotation gear 17c that meshes with the gear 18c of the potentiometer 15 to be rotated and the front rotation gear 17f are both supported by the outer rotation support pipe 16e of the rotation device 17. Thus, by not having a counter gear or the like, the backlash is reduced, thereby reducing the error and improving the detection accuracy of the potentiometer 15. Accordingly, the control by detection is also improved.

  As shown in FIG. 1 and FIG. 2, a discharge cylinder 14 having a discharge port 14 a for discharging the grain to the outside of the machine is rotatable at the transfer terminal portion of the grain transfer / discharge cylinder device 6 for transferring and discharging the grain. The rotation motor 14b for rotating the discharge cylinder 14 is provided at the front end of the grain transfer / discharge cylinder device 6 in the outer shape portion. Since the motor 14b does not protrude upward, for example, the combine 1 can prevent the overall height from increasing. Further, when moving on the field and when traveling on the road, the remaining cereal remaining in the grain transfer / discharge cylinder device 6 from the shed port 14a of the discharge cylinder 14 by rotating the discharge cylinder 14 upward. The grains are stored in the ceiling portion (b) of the discharge cylinder 14 so that leakage to the outside of the machine can be prevented and the loss of grains can be prevented.

  In addition, the discharge cylinder 14 having the grain outlet 14a rotatably provided at the transfer terminal end of the transfer cylinder 13 for movement of the grain transfer / discharge cylinder device 6 is provided with a rotation motor 14b to be rotated. Therefore, as compared with the conventional configuration in which the entire grain transfer / discharge cylinder device 6 is rotationally moved, the small-horsepower rotating motor 14b may be used, and the rotational configuration is simple.

  As shown in FIGS. 1 and 2, the discharge cylinder 14 having a grain outlet 14 a rotatably provided at a transfer terminal end of the transfer cylinder 13 for movement of the grain transfer / discharge cylinder device 6 is a transfer cylinder 13 for movement. The overall width (L3) in the left and right direction of the shed port 14a at the lower end of the left and right side plate 14d of the discharge cylinder 14 is larger than the outer diameter (D).

  By providing the full width (L3) in the left-right direction of the grain outlet 14a portion of the discharge cylinder 14 larger than the outer diameter (D) of the transfer cylinder 13 for movement of the grain transfer / discharge cylinder device 6, It is possible to increase the discharge efficiency of the grain at the discharge port. Moreover, it is the structure which can prevent the clogging of the grain in this grain outlet 14a.

  The fixed transfer cylinder 8 of the grain transfer / discharge cylinder device 6 and the transfer cylinder 13 inserted into and supported by the fixed transfer cylinder 8 are arranged in the circumferential direction as shown in FIGS. Is a structure which is not rotationally moved. The discharge cylinder 14 provided on the transfer terminal end side of the transfer cylinder 13 is configured to rotate in the circumferential direction. The discharge cylinder 14, the motor cover 14c, and the harness cover 15b simultaneously rotate in the circumferential direction.

  Thereby, only the discharge cylinder 14 is configured to rotate in the circumferential direction by the rotation of the rotation motor 14b, so that the rotation motor 14b can have a small horsepower. Further, the discharge cylinder 14 can be easily disassembled and assembled.

  Due to the “ON” operation of the detection switch 25a, the grain discharging operation is not started immediately, but based on this “ON” input, the moving transfer cylinder 13 of the grain transfer discharging cylinder device 6 is moved to the transfer terminal end side. The rotational movement position of the grain outlet 14a of the provided discharge cylinder 14 is detected by the potentiometer 15 and input to the control device 21f. When the input rotational movement position is set to the undischargeable position range in which the grain is discharged from the grain outlet 14 a, the grain outlet 14 a of the outlet cylinder 14 is connected to the rotation device 17. The rotation motor 14b is controlled to start by the control device 21f, the threshing port 14a is controlled to rotate to the position immediately below, and this is detected by the potentiometer 15, and this detection is input to the control device 21f. When it is determined that the grain mouth 14a is in the position immediately below, the grain discharge operation is controlled to start by the operation of the discharge clutch 25a “ON”.

  Further, when “ON” of the discharge switch 25a is inputted and the rotational movement position of the culling port 14a of the discharge tube 14 is in the dischargeable position, when it is determined by the detection of the potentiometer 15 as it is. This is a configuration in which the grain discharge operation is started and controlled by “ON” of the discharge switch 25a.

  When the discharge switch 25a operated to rotate and drive the grain transfer path for transferring and discharging the grain is “ON”, this “ON” is input to the control device 21f, but the discharge operation is not immediately controlled. When the rotation position of the culling port 14a of the discharge cylinder 14 is detected by the potentiometer 15 and is within the position where the discharge cannot be performed, the rotation motor 14b of the rotation device 17 is controlled to start by the control device 21f. Then, after the grain outlet 14a is controlled to rotate and move downward, the grain discharging operation is started, so that clogging of the grain can be prevented. In addition, when the shed port 14a is in the dischargeable position range, the discharging operation can be performed after the shed port 14a of the discharge tube 14 is rotated to an arbitrary angular position.

  When the discharge switch 25a is in the “ON” state, the shed port 14a of the discharge tube 14 is rotated by an external force. At this time, the shed port 14a of the discharge tube 14 is in the undischargeable position range. If it is detected by the potentiometer 15 and determined by the control device 21f, the discharge switch 25a is changed to "OFF" by the control device 21f.

  When the discharge switch 25a is "ON", the grain outlet 14a of the discharge cylinder 14 is rotated by an external force, and when the discharge switch 25a is in the non-dischargeable position range, the control device 21f sets the discharge switch 25a to " By changing the control to “OFF”, it is possible to prevent the grain clogging in the grain transfer / discharge cylinder device 6.

  The discharge switch 25a is configured to be “ON”-“OFF”. With this “ON”-“OFF”, the lamp 25b provided to the discharge switch 25c is configured to “turn on” — “flash” — “turn off”.

  The lamp 25b blinks when the discharge switch 25a is “ON”, and the lamp 25b continues to blink until the grain outlet 14a of the discharge tube 14 moves downward. Further, as the grain transfer / discharge cylinder device 6 or the like starts rotating the grain discharge operation, the lamp 25b is controlled to be changed from blinking to lighting by the control device 21f. Further, when the discharge switch 25a is operated to “OFF”, this “OFF” is input to the control device 21f, and by this “OFF”, the lamp 25b is controlled to be turned off by the control device 21f. .

  By changing the lamp 25b from blinking to lighting based on the “ON” of the discharge switch 25a and the rotational movement position of the shed port 14a of the discharge cylinder 14, the operation position of the discharge cylinder 14 is visually determined. It became easy to understand. Moreover, it is possible to prevent erroneous operation.

  When the discharge switch 25a is “ON”, this “ON” is input to the control device 21f. By this input, the rotation motor 14b of the rotation device 17 that rotates and moves the cereal outlet 14a of the discharge cylinder 14 is controlled to start by the control device 21f, and the cereal outlet 14a of the discharge cylinder 14 is positioned directly below. Is controlled to rotate. When the potentiometer 15 detects the rotational movement and is input to the control device 21f to determine that the position is in the directly lower position, the rotational movement of the discharge tube 14 is controlled to be stopped and held at the lower position. It is a configuration.

  As a result, when the discharge switch 25a is turned “ON”, the shed port 14a of the discharge tube 14 can be automatically directed downward, so that the trouble of turning the shed port 14a of the discharge tube 14 downward can be saved. Also, the operation is simplified.

  By operating the automatic telescopic switch 25d that is operated when the grain transfer / discharge cylinder device 6 is stored in the storage position, the fixed transfer cylinder 8, the transfer cylinder 13 and the discharge of the grain transfer / discharge cylinder device 6 are discharged. Even if the cylinder 14 and the like are raised, and the tip of the discharge cylinder 14 is raised to the uppermost position, the cereals 14a of the discharge cylinder 14 are waited for the threshing port 14a to rotate upward before these grains. A turning motor 32 for turning the transfer and transfer cylinders 8 and 13 for fixing and moving the particle transfer / discharge cylinder device 6 and the discharge cylinder 14 and the like is rotationally driven by the control device 21f. Thereby, turning control is started for the grain transfer / discharge cylinder device 6 to the storage position.

  Thereby, even if the front-end | tip part of the discharge cylinder 14 of the said grain transfer discharge cylinder apparatus 6 raises to the uppermost position, after turning on after the grain outlet 14a of the discharge cylinder 14 faces upwards, turning control is performed. By being started, the grain in the discharge cylinder 14 by the impact at the start of turning, for example, when discharged to the grain transporter, means that the grain is scattered outside the grain transporter. Can be prevented.

  When the discharge switch 25a is "ON", this is for automatic storage even when the automatic expansion / contraction switch 25d operated for automatic storage is operated "ON". Ignoring the input of the “ON” operation of the automatic expansion / contraction switch 25d, the automatic storage control is not subjected to change control.

  Thus, when the discharge switch 25a is “ON”, the input of the “ON” operation of the automatic expansion / contraction switch 25d for automatic storage is ignored, so that the automatic storage is erroneously performed during the grain discharge. And even if it is discharging | emitting a grain to a grain conveyance vehicle, the grain transfer discharge cylinder apparatus 6 can prevent that a grain is sprinkled out of a grain conveyance vehicle by not being operation-controlled. .

  By automatically turning on the automatic expansion / contraction switch 25d to be operated when the grain transfer / discharge cylinder device 6 is automatically stored. In the automatic storage control, after the grain transfer / discharge cylinder device 6 starts the ascent control, the grain outlet 14a of the discharge cylinder 14 is directed upward and the rotational movement is controlled to start.

  Thereby, after the grain transfer / discharge cylinder device 6 is started to be lifted, the grain outlet 14a of the discharge cylinder 14 is controlled to rotate and move upward, so that the discharge cylinder 14 carries the grain. It can be prevented from coming into contact with the cargo bed of the car.

  When the grain transfer / discharge cylinder device 6 is automatically stored, the automatic expansion / contraction switch 25d is operated to perform automatic storage control by the “ON” operation, and the grain outlet 14a of the discharge cylinder 14 is directed upward. In the configuration in which the grain transfer / discharge cylinder device 6 is housed in the auger receiving device 33 after being turned and moved, when the discharge switch 25a is “ON”, the shed 14a of the discharge cylinder 14 is directed upward. In this configuration, the grain transfer / discharge cylinder device 6 is stored in the auger receiving device 33 without controlling the rotational movement.

  Thereby, at the time of automatic storage control when the discharge switch 25a is “ON”, the grain transfer discharge cylinder device is stored in the auger receiving device 33 without facing the grain outlet 14a of the discharge cylinder 14 upward. The clogging of the grain within 6 can be prevented.

  The potentiometer 15 for detecting the rotational movement position of the discharge cylinder 14 is a space above the rear rotational gear 17c that is pivotally supported on the outer rotational support pipe 16e of the rotational device 17 as shown in FIGS. It is the structure provided in the part (A).

  The potentiometer 15 is provided in the space (a) above the rear rotation gear 17c that is pivotally supported by the outer rotation support pipe 16e of the rotation device 17, so that the configuration is simple and compact. It is the structure which can do.

  As shown in FIGS. 1 and 2, the potentiometer 15 is provided on the front side of the support metal 18a at the top of the rotation device 17, and detects the number of rotations of the support shaft 18a.

  Since the potentiometer 15 is provided on the support metal 18a at the upper part of the rotation device 17, the rotation movement position can be accurately detected because the weight of the gear 18c is not affected.

  The rotating device 17 provided on the front side plate 14e of the discharge cylinder 14 and the motor cover 14c that covers the rotation motor 14b and the like are detachable from the front side plate 14e of the discharge cylinder 14 as shown in FIGS. This is a configuration provided.

To the front end of the support shaft 16c, which is formed in a substantially vertical shape and has a full width in the front-rear direction (L1), and is mounted on the outer lid 13b of the transfer cylinder 13 for movement. The screw-inserted nut 16h portion is provided with a protruding portion 14m protruding in a mountain shape toward the front outer side, and the inner side surface of the protruding portion 14m and the nut 16h are provided with a predetermined gap (minimum). The motor cover 14 c is configured to rotate and move simultaneously with the discharge cylinder 14.

  The motor cover 14c is provided so as to cover the rotation device 17 provided on the front side of the front plate 14e of the discharge cylinder 14, the rotation motor 14b, and the like, and the rear side portion of the motor cover 14c is an open box. The front plate is formed in a substantially vertical shape, and the entire width in the front-rear direction (L1) is formed to be narrow, and the nut 16h portion screwed into the front end portion of the support shaft 16c extends to the front outer side. The motor cover 14c can be made compact by adopting a configuration in which the projecting portion 14m projecting in a mountain shape is provided. Moreover, the large grain receiving bag for receiving the discharged grains can be easily attached to and detached from the discharge cylinder 14.

  The upper full width (L2) and the lower full width (L3) in the left-right direction of the discharge cylinder 14 and the motor cover 14c are formed to have substantially the same width as shown in FIG. The outer diameter (D) is a configuration that is formed wider than a predetermined width.

  The upper full width (L2) and the lower full width (L3) of the discharge cylinder 14 and the motor cover 14c in the left-right direction are formed to be substantially the same width, and the outer diameter (D ), The discharge cylinder 14 and the motor cover 14c are compact because they are formed to have a predetermined width. Moreover, it is easy to attach and detach the large grain receiving bag that receives the discharged grain.

  As shown in FIGS. 1 and 2, the discharge cylinder 14 is pivotally moved between the upper side surface of the discharge cylinder 14 and the upper side surface portion of the motor cover 14c. This is a configuration in which a harness cover 15b that covers a harness 15a that connects the rotating motor 14b provided on the front side of the discharge cylinder 14 and the operating device 21a is detachably provided.

  As shown in FIG. 2, the harness cover 15b has a substantially U-shaped configuration with a predetermined width in the left-right direction and a predetermined height in the vertical direction. The harness cover 15b has a configuration in which a substantially L-shaped mounting plate 14n is fixedly provided on the upper side surface of the discharge cylinder 14, and is superposed on both the left and right outer surfaces of the mounting plate 14n to provide bolts, nuts, and the like. Thus, the configuration is provided by mounting. Further, the front end portion of the harness cover 15b has a configuration in which an inclined surface 15c that is inclined at a predetermined angle (θ) from the rear upper portion to the front lower portion is formed.

  A harness cover 15b that covers the harness 15a of the rotation motor 14b that rotates the discharge cylinder 14 is provided on the upper side surface portion of the discharge cylinder 14 and the upper side surface portion of the motor cover 14c. By providing the inclined surface 15c of a predetermined angle (θ) that inclines toward the front lower part, it is easy to attach and detach the large grain receiving bag for receiving the discharged grain to the discharge tube 14 part.

  In the ceiling of the motor cover 14c, a rectangular opening 14j is provided as shown in FIGS. The harness 15a provided to the rotation motor 14b is configured to be connected to the operating device 21a through the harness cover 15b through the opening hole 14j in the ceiling of the motor cover 14c. The harness 15a is a normal harness 15a from the rotating motor 14b to the front coupler 34a, and the harness 15a from the rear coupler 34b to the rear end of the harness cover 14c is formed in a spring shape. The harness 15a is configured to be expanded and contracted by a spring-like portion with respect to the rotational movement of the discharge cylinder 14. The harness 15a is configured to be mounted on the upper outer side surface of the transfer cylinder 13 by a clamp 34c on the rear side of the harness cover 15b.

  Thereby, even if it provides the opening hole 14j which lets the said harness 15a pass, the fall of an external appearance shape can be prevented by being covered with the harness cover 14c. In addition, since a part of the harness 15a is formed in a spring shape, even if the discharge cylinder 14 is rotated, the harness 15a is expanded and contracted by the spring-like portion, thereby preventing a problem from occurring during the rotation. It is a configuration that can.

  The harness 15a of the rotating motor 14b is inserted into the harness cover 15b via one side of the left and right attachment portions of the support metal 18a to which the potentiometer 15 is attached as shown in FIGS. This is a configuration provided. At this time, the support metal 18a is arranged above the center of the support shaft 16c provided on the outer lid 13b of the transfer cylinder 13 for movement.

  Thereby, the harness 15a of the rotation motor 14b can be disposed above the axis of the rotation movement of the discharge cylinder 14.

  As shown in FIG. 1, the front turning gear 17f that is pivotally supported by the outer rotation support pipe 16e that is pivotally supported by the support shaft 16c that is pivotally supported by the outer lid 13b that is provided at the tip of the transfer cylinder 13 is a dish. This is a configuration in which the entire width in the front-rear direction of the rotation fulcrum portion 16d of the rotation device 17 is narrowed by being pivotally supported in front of the spring 17e.

  As a result, the overall width of the motor cover 14c in the front-rear direction can be narrowed. For this reason, the overall width of both the discharge cylinder 14 and the motor cover 14c is narrowed, and a large grain is received. Easy replacement of grain bag.

  The motor cover 14c and the harness cover 15b were removed and screwed into the front outer end of the support shaft 16c. By removing the nut 16h, it is possible to remove as a partial assembly of the discharge cylinder 14 including the discharge cylinder 14 and the rotation fulcrum portion 16d of the rotation device 17.

  As a result, by removing the nut 16h screwed into the support shaft 16c, it can be removed as a partial assembly of the discharge tube 14, thereby reducing the number of man-hours for disassembly. Further, each of the gears 17b, 17c, 17f, and 18c is disassembled in a meshed state so that the relational position between the potentiometer 15 and each of the gears 17b, 17c, 17f, and 18c does not change.

  To increase the overall height of the auger receiving device 33 that supports a predetermined position of the front portion of the fixing transfer cylinder 8 of the grain transfer / discharge cylinder device 6, conventionally, the discharge cylinder 14 portion should be positioned upward at a predetermined angle, The front tip portion was a high position and the rear base portion was a low position, and it was configured to be inclined at a predetermined angle. As shown in FIG. 20, the overall height of the receiving column 33a of the auger receiving device 33 is lowered so as to be supported in a substantially horizontal state in the front-rear direction, and a receiving guide 33b is provided at the upper end of the receiving column 33a. The guide 33b is supported in a substantially horizontal state. Further, the storage space for the combine 1 can be reduced by reducing the ground clearance of the fixing transfer cylinder 8 and the transfer transfer cylinder 13.
