Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention provides a grain discharge auger for combine harvesters, which discharges the grains sent from the threshing unit and stored in a grain tank mounted on a machine stand equipped with a traveling device to appropriate places outside the machine. The present invention relates to a lock device that locks a brake in a discharge state.

[0002]

[Prior Art]

 Conventionally, as a grain discharging auger lock device for combine harvesters, like the one disclosed in Japanese Utility Model Laid-Open No. 63-24445, the grain in the grain tank is swirled and discharged to an appropriate place outside the machine by rotating at the time of work. The discharge auger is locked at the storage position after the work is completed.

[0003]

[Problems to be solved by the device]

 As described above, the conventional discharge auger lock device locks the discharge auger at the storage position after the completion of the discharge work outside the machine. Since there is no means to maintain the discharged state when discharging the grains in the tank into place, the swing operation lever for rotating the lifting cylinder is operated to swivel the discharge auger to the neutral position. The turning operation is stopped, and the grain is discharged to the proper place.The grain is discharged from the machine so that the discharge ogre naturally moves and the grain discharge position shifts, causing the grain to drop to an unexpected location. End up. Especially when the machine is tilted and discharged from the discharge auger, the natural movement of the discharge auger becomes remarkable, so the present invention sets the discharge auger to a suitable position. It was devised for the purpose of preventing braking of the grain to an unexpected place due to natural movement by sometimes braking locking in the discharged state.

[0004]

[Means for Solving the Problems]

 Therefore, in the present invention, in order to achieve the object described in the preceding paragraph, a thresher section and a grain tank for storing the grains from this threshing section are mounted on a machine platform equipped with a traveling device, When the grain in the grain tank is discharged to a proper place outside the machine by a discharge auger that is installed and rotatable and extends horizontally from the upper end of the fried barrel, A brake device for locking the brake is provided, and the brake device is configured to lock the brake only when the turning operation lever for rotating the fried container is in the neutral position.

[0005]

[Action]

 With this configuration, the grain is stored in the grain tank from the threshing unit and is moved to move it outside the machine in an appropriate place, and then the turning operation lever is operated to operate the turning cylinder. When the discharge auger is swung along with the rotation to bring it to the neutral position and the turning is stopped to put it in a discharge state to a proper position, the brake device is activated along with this to brake and lock the fried food cylinder, and the discharge auger is operated as described above. It is possible to reliably maintain the discharge state and continue discharge to the proper place.

【Example】

 Hereinafter, the device according to the present invention will be described in detail with reference to the drawings. Before that, the outline of the whole combine to which the device is applied will be described. A frame-structured machine stand mounted on a traveling device (1) of the type, a threshing section (A) is mounted on the left side of the machine stand (2), and a control section (C) is installed on the right side from the front side section. A grain tank (G) and an engine room (E) are arranged, and a cutting section (5), a raising case (6) and the like in front of the threshing section (A) ( D) are connected in series, and a straw treatment unit (F) is provided behind the threshing unit (A).

[0007] Further, at the bottom of the grain tank (G), a grain extraction gutter (7) extending rearward through the engine room (E) is provided horizontally. A fried grain cylinder (3) is erected on the rear side in an upright state, and a discharge auger (4) extends horizontally from the upper end portion to the front side.

And, the above-mentioned fried cylinder (3) is supported by a bracket (8) on the upper side, and the lower end is supported by the rear end of the above-mentioned grain extraction gutter (7) to provide a vertical shaft core. The unloader (4) is rotatably erected around the container, and the discharge auger (4) is rotated in a horizontal state with the rotation of the fried cylinder (3) and is stored in the grain tank (G). The grain is inherited from the grain extraction trough (7) by the lifting cylinder (3) and the discharge auger (4) and discharged from the discharge port (9) at the tip to a proper place outside the machine.

As described above, in order to rotate the fried food barrel (3) around the vertical axis, the gear (10) is fitted to the outer peripheral wall of the lower end portion of the fried food barrel (3). The gear (10) is provided with a drive gear (12) axially attached to a shaft of a turning motor (M) attached to a room frame (11) constituting the engine room (E). Through the turning switch (S), the meshing operation, the control section (C) or the turning operation lever (R) provided at an appropriate position of the body is tilted to the left or right from the upright neutral position. The fried food barrel (3) is rotated by rotating the motor (M) forward or backward.

The discharge ogre (4) can be moved up and down with the base extending from the upper end of the fried food barrel (3) as a fulcrum, and the position of the discharge port (9) at the tip end is higher. Or the position can be changed to a lower position.

Next, the structure and operation of the main part of the present invention will be described. (B) is a brake device that brakes and locks the rotation of the fried food barrel (3). ) Side, and a break arm (14) having a band (13) concentric with the outer peripheral wall of the fried cylinder (3) is swung about the vertical axis (15) as a fulcrum. The band (13) is brought into contact with or separated from the outer peripheral wall surface of the fried grain cylinder (3) by means of the break arm (14) and the tension spring (16) is connected to the band (13). The rotation of the fried food barrel (3) is constantly pressed against the wall surface so as to brake and lock the rotation.

Further, (M1) is an operation motor for releasing the brake device (B), and the tip of the motor arm (17) of the operation motor (M1) and the breaker. -A link (18) interlocks with the vicinity of the extension spring (16) connecting part of the ram (14), and the operating motor (M1) moves to the left or right of the turning operation lever (R). The brake arm (14) is electrically connected to the tilting operation and is activated during the tilting operation to resist the tensile force of the tension spring (16) through the motor arm (17) and the link (18). ) Is swung to separate the band (13) which is pressed against the outer peripheral wall surface of the fried food barrel (3) from the wall surface to release the braking lock.

As a result, when the turning operation lever (R) is tilted to either the left or right side as shown in (a) and (b), the operation motor (M1) is turned on and the operation is performed as shown in (c). When activated, the band (13) is separated from the outer peripheral wall surface of the fried grain cylinder (3) to release the braking lock, and with this release, the turning operation lever (R) is operated to the left as shown in (a). At this time, the swivel motor (M) is normally rotated through the swivel switch (S), and when the swivel motor (M) is operated to the right as shown in (b), the swivel motor (M) is reversed and the fried grain is fried. The discharge auger (4) turns together with the rotation of the tube (3) to move the discharge port (9) toward a proper discharge position.

When the moving discharge port (9) reaches the proper discharge position, the turning operation lever (R) is returned to the neutral position in the upright state, and the turning motor (M) is energized. When the (S) is turned off, it is cut off, and the rotation of the fried food barrel (3) is stopped and the turning of the discharge auger (4) is stopped. At the same time, the operation motor (M1) is also turned off, and the break arm (14) swings about the vertical axis (15) as a fulcrum by the tensile force of the tension spring (16) and the band (13). Is pressed against the outer peripheral wall surface of the fried food container (3) to lock the fried food container (3) by braking and maintain the discharge auger (4) in a discharge state in which the discharge port (9) is located at a suitable discharge position. The grain picked up from the grain tank (G) by the grain pick-up gutter (7) and the lifting cylinder (3) is taken over by the discharge auger (4) and discharged at the tip. It is reliably discharged from the outlet (9).

It is also conceivable to use the turning motor (M) with a brake device (built-in type). That is, according to this motor, the turning switch (S) is turned on, the brake is turned off while the discharge auger (4) is turning, and the turning switch (S) is turned off. The key is turned on to lock the rotation of the fried food barrel (3) and prevent the discharge auger (4) from moving naturally.

Further, as shown in FIG. 3, the switches (S1) (S2) sandwiching one tooth (10a) of the gear (10) fitted on the outer peripheral wall of the fried food barrel (3). Respectively, and the discharge auger (4) naturally moves while discharging the grain from the discharge port (9) at the tip of the discharge auger (4), which moves the lifting grain cylinder (3). If the rotation causes the switch (S1) to turn on if it moves as shown by an arrow (d), the turning motor (M) moves the switch in the opposite direction so that one tooth (10a) is switched. It is also possible to modify so that it is located between (S1) and (S2) so that the discharge state of the discharge auger (4) can be maintained.
