Abstract

<P>PROBLEM TO BE SOLVED: To provide an auger actuator that does not drop grains on the outside even in the case where the auger turning operation is carried out while the discharging auger is allowed to turn so that the top outlet is moved on the upper face of the track carrier or a grain container and the grain is discharged from the auger cylinder. <P>SOLUTION: In an combine harvester that is equipped with a lifting member 30 for ascending and descending the grain-discharging auger 17 and with a turning member 27 for allowing the auger 17 to turn around, when the moving clutch of the discharging auger 17 is switched on under the condition where the discharge auger 17 is actuated, the switching-off of the clutch of the discharging auger 17 is started and simultaneously the top end of the discharging auger 17 is allowed to start lifting slowly. After a prescribed time has passed, the switch-off of clutch of the discharging auger 17 is ended, simultaneously the high speed lifting of the top end of the discharging auger 17 is started, and then the rotation is restarted, after the rotation of the discharging auger 17 is stopped. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a combine auger operating device including a discharge auger that collects grains that have been continuously harvested and threshed in a grain tank, and takes out the grains from the grain tank.

Conventionally, in the combine, the auger tube is rotated (turned) while the auger is swung and the tip outlet is moved to the upper surface of the truck bed or container to discharge the grain from the auger. In this case, the discharge auger clutch is configured to be automatically “disconnected”.
However, in such a conventional apparatus, the auger clutch is cut off while the auger cylinder is automatically raised, but the grain discharge does not stop immediately. Occur.
JP 6-42807

  Therefore, an object of the present invention is to eliminate the above-mentioned problem, that is, in the combine, the discharge auger is swung and the tip outlet is moved to the upper surface of the truck bed or container to discharge the grain from the auger cylinder. It is another object of the present invention to provide an auger operating device for a combine that prevents grains from spilling outside even when an auger return operation is performed.

In order to solve the above problems, a combine auger operating device for a combine according to the present invention is a combine provided with an elevating member for raising and lowering the discharge auger and a turning member for turning the auger. When the moving clutch is engaged, the "disengagement" of the discharge auger clutch is started and the tip side of the discharge auger is started to rise at a low speed. Is started at a high speed, and then the auger cylinder is rotated after the rotation of the discharge auger is stopped.
In the combine auger operating device for a combine according to the present invention, in the above-mentioned means, the end of the “disengagement” of the clutch of the discharge auger is after a predetermined time has elapsed from the start of the “disengagement” of the clutch of the discharge auger. .

The combine auger operating device of the present invention adopts the above-mentioned means, so that the grain spills to the outside even when the rotation (auger return) operation is performed while the grain is being discharged from the auger. There is an advantage that there is no.
In addition, when the auger starts to rise at a low speed by the switch operation, the operator can recognize that the storing operation has started, and can rise at a low speed to reduce grain scattering. Furthermore, there is a high possibility that an operator is also present in the discharge section during the discharge operation, but the auger operates at a low speed at the beginning of movement, and thus safety is further improved.
Furthermore, the above-described effect can be realized with a simple and reliable configuration by ending the “disengagement” of the clutch of the discharge auger after a predetermined time has elapsed from the start of the “disconnection” of the clutch of the discharge auger.

It is composed.

(Ogre storage control)
Next, auger storage control will be described with reference to FIG.
In addition to the above configuration, when the auger clutch switch 48 is in the ON state (the auger clutch is in the engaged state) and the storage switch 47 is operated, the hydraulic auger lifting / lowering cylinder 30 that lifts and lowers the distal end side of the discharging auger 17 The auger 17 tip side starts to rise at a low speed, and at the same time, the auger clutch 60 starts to be driven to the “disengagement” side. By the “cutting” driving of the auger clutch 60, the discharge auger 17 is not stopped immediately, and the rotation of the discharge auger 17 is stopped after a predetermined time (seconds) has elapsed.

(Auger clutch 60)
For example, as shown in FIG. 8, the auger clutch 60 is provided in the vicinity of a lateral feed auger (not shown) below the glen tank 15 provided on the machine base 3. An input pulley 61 that is directly connected to the lateral feed auger is disposed below the Glen tank 15, and a drive pulley 62 that transmits the driving force of the engine 21 is disposed apart from the input pulley 61 by a predetermined distance. Is connected to an input pulley 61 via a belt 63. A tension roller 64 is arranged on the belt 63 so as to come into contact with the belt 63, and the tension roller 64 is connected to the clutch motor 65 via a link mechanism including a screw mechanism 66 and two-point links 67 and 68. ing.

  The screw mechanism 66 includes a screw rod 66b that is rotated by a clutch motor 65 and a nut 66a that is screwed into a male screw portion of the screw rod 66b, and one end of the one link 67 rotates in the nut 66a. The other end of the link 67 is fixed to the other link 68 at a predetermined angle, and the fixing point is pivotally supported on the machine base 3 side. An input pulley 61 is pivotally supported at the other end of the other link 68.

  With the configuration described above, time difference control is realized in which the input pulley 61 is rotated or stopped and the auger is driven or stopped by the movement of the nut 66a under the control of the clutch motor 65. And the grain in the Glen tank 15 is carried out by the drive of an auger. The transmission mechanism of the auger clutch 60 or the input pulley 61 may be an electronic configuration.

  When the auger clutch is completely in the “disengaged” state, the ascending speed on the auger tip side is switched at a high speed. Note that it is desirable that the confirmation of the “disengaged” state of the auger clutch is performed in the time from the start of the limit switch or “disengagement” driving. And after that, the same storing operation as before is performed. Note that instead of “after the predetermined time (seconds) has elapsed”, the remaining state of the grains in the auger tube may be sensed, and the value of this sensing sensor may be used.
