  By providing the motor cover 13e that covers the rotating motor 13b and the various gears 13c, 12a, 12d, 12h, etc., it is safe and the appearance can be improved. Further, the outer shape of the motor cover 13d is formed in substantially the same shape as the cross-sectional shape of the discharge cylinder 11, and is provided so as to be detachable, so that the outer shape can be greatly increased. Also, maintenance is easy.

  As shown in FIGS. 3, 14, and 15, the discharge cylinder 11 having a discharge port 11 a rotatably provided at the transfer terminal end of the transfer transfer cylinder 10 of the grain transfer discharge cylinder device 8 moves as shown in FIGS. 3, 14, and 15. The width (L) of the discharge port 11a portion of the discharge tube 11 is formed to be larger than the outer diameter portion (D) of the transfer tube 10 by a predetermined size.

  The grain is discharged by providing a width (L) of the discharge port 11a of the discharge tube 11 larger than the outer diameter (D) of the transfer tube 10 for movement of the grain transfer / discharge tube device 8. This can increase the emission efficiency. Moreover, the clogging of the grain at the outlet 11a can be prevented.

As shown in FIG. 14 and FIG.

  By providing brake plates 12b and 12b on both the front and rear sides of the rear rotating gear 12a, when the discharge cylinder 11 comes into contact with an obstacle and a strong force is applied, each brake plate 12b portion slips, and this discharge By rotating the cylinder 11, the discharge cylinder 11 can be prevented from being damaged. Further, even when a trouble occurs in the rotation motor 13b and the rotation of the discharge cylinder 11 is not controlled by the rotation motor 13b, the brake plates 12b and 12b are provided. By applying a strong force manually by the operator, the discharge cylinder 11 can be rotated, and it is possible to prevent the grain from being discharged.

  As shown in FIGS. 14 and 15, a lid-shaped outer lid 10 f is fixedly provided at the transfer terminal portion of the opening 10 e of the transfer cylinder 10 for movement of the grain transfer / discharge cylinder device 8. The lid 10f is provided with a support plate 31a, and the support plate 31a is provided with a front support metal 31 via a cushion body 31b made of an elastic material. Is supported.

  As a result, the assembly of the transfer terminal portion of the transfer cylinder 10 can be performed in the previous stage of assembling the rotating device 13, thereby facilitating assembly and reducing the number of assembly steps. .

  As shown in FIGS. 14 and 15, a flange portion for attaching a circular outer lid 10 f is provided at the transfer terminal end portion on the front side of the opening 10 e of the transfer tube 13 for movement of the grain transfer / discharge tube device 8. Has a configuration in which it is inserted inwardly into the inner diameter portion of the transfer cylinder 10 and mounted, but as shown in FIGS. 14 and 15, this is a flange portion for mounting the outer lid 10 f. Are inserted toward the outside of the inner diameter of the transfer cylinder 10 for movement.

  As a result, the flange portion for mounting the circular outer lid 10f to be inserted into the transfer cylinder 13 is inserted and attached to the outer side so that the grain is attached to the flange portion for mounting the outer lid 10f. Grains can be prevented from accumulating, and for this reason, it is possible to prevent grains that have leaked from the discharge port 11a of the discharge cylinder 11 during traveling after the completion of the grain discharge during the harvesting operation of the cereal.

  Conventionally, the height of the auger receiving device 36 that supports a predetermined position of the front portion of the fixed transfer cylinder 9 of the grain transfer / discharge cylinder device 8 is increased so that the discharge cylinder 11 portion is conventionally positioned upward at a predetermined angle. The front tip portion is a high position and the rear base portion is a low position, and is inclined and inclined at a predetermined angle. As shown in FIG. 1, the overall height of the receiving column 36a of the auger receiving device 36 is lowered so as to be supported in a substantially horizontal state in the front-rear direction, and a receiving guide 36b is provided at the upper end of the receiving column 36a. This receiving guide 36b is supported in a substantially horizontal state. Moreover, the storage space for the combine is made low by lowering the ground clearance of the fixing transfer cylinder 9 and the transfer transfer cylinder 10.

Is controlled to rotate upward by a control device 19a provided in the apparatus.

  Thereby, when there is no grain in the storage tank 6, even if the grain transfer / discharge cylinder device 8 is automatically stored, the discharge port 11a of the discharge cylinder 11 is not moved upward, which is unnecessary. In some cases, the discharge port 11a faces downward, which is convenient when the body cover is mounted.

Below the storage tank 6 is provided an “ON”-“OFF” type grain detection sensor 6 a that detects the presence or absence of a grain.
When the grain detection sensor 6a is "ON", the movable transfer cylinder 10 of the grain transfer / discharge cylinder device 8 is not completely moved and controlled in the housed state.

  Thereby, when there is a grain in the storage tank 6, the movement transfer cylinder 10 is not completely moved and controlled in the housed state, so that the remaining kernel in the grain transfer / discharge cylinder device 8 may be compressed. This eliminates the possibility that the grain transfer / discharge cylinder device 8 will be damaged.

  An “ON”-“OFF” type limit switch 8b is provided in the middle portion of the fixed transfer cylinder 9 of the grain transfer / discharge cylinder device 8 and is used for movement when the grain detection sensor 6a is “ON”. When the transfer cylinder 10 is automatically stored and moved, the movement control is performed until the limit switch 8b is turned on so that the transfer cylinder 10 for movement is not completely stored. Alternatively, a timer is provided, and the movement control is performed with the timer until the transfer cylinder 10 is moved to a position of about half.

  Thereby, when there is a grain in the storage tank 6, even if the transfer cylinder 10 for movement is automatically stored, even if there is a residual grain by controlling so as not to contract completely, It is possible to prevent the grain transfer / discharge cylinder device 8 from being damaged without being compressed.

  The timer 19e provided in the operation device 19 detects the "on" time of the discharge clutch lever 19d, and from the set discharge time, the "on" time of the discharge clutch lever 19d is detected to be short. Sometimes, the transfer cylinder 10 for movement is not automatically controlled to be completely contracted.

Thereby, even when there is a residual grain, the grain is not compressed and the grain transfer / discharge cylinder device 8 can be prevented from being damaged.
An “ON”-“OFF” type limit switch 8 b is provided in the middle portion of the fixing transfer cylinder 9, the discharge time is set in advance, and the timer 19 e of the operating device 19 “in” the discharge clutch lever 19 d. When the time is detected and it is detected that it is shorter than the set time for discharge, when the transfer cylinder 10 is moved to the automatic contracted state, the limit switch is in a state where the transfer cylinder 10 is not completely stored. This transfer cylinder 10 is controlled to be stored until 8b is controlled to be “ON”. Further, the movement transfer cylinder 10 is controlled to be approximately half stored by the timer 19e.

Thereby, the grain in the said grain transfer discharge cylinder apparatus 8 is not compressed, and damage to this grain transfer discharge cylinder apparatus 8 can be prevented.
