Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a movable structure of a waste auger in a threshing machine.
[0002]
[Prior art]
The grain threshed by the threshing machine is discharged from the waste auger and received by an appropriate receiver. In this case, the waste auger can be moved to align the position with the receiving body. In particular, if the threshing machine is a moving type like a combine, it will be harvested while moving. It is possible to align as possible. In this case, since the position of the waste auger is frequently adjusted, in addition to the permanent operation panel provided in the cockpit, etc., a remote control operation panel that can be carried and operated by an assistant is provided. Both can be operated (for example, JP-A-3-130011).
[0003]
By the way, in a combine etc., each apparatus is mounted in a dense state because of space or the like, and the slag auger turns right above the slag tank or threshing machine. Therefore, it is necessary not to interfere with these when raising and lowering and turning, and of course not harming the pilot sitting in the cockpit. Therefore, the raising and lowering of the waste auger is generally not lowered from the horizontal posture, and the danger area is detected and the swirling and raising and lowering of the waste auger are restricted within this range for safety. (For example, JP-A-5-015245).
[0004]
[Problems to be solved by the invention]
On the other hand, in addition to moving the dredge to the dredging vehicle, there is a case where a small bag is placed on the ground and then moved to this (in this case, the bag is not only stopped on the ground but also held by the person. May be moved together). In such a case, if the evacuation auger does not fall below the horizontal posture, the heel is dropped from a high place and there is a risk of spilling around. In view of this, the present invention provides a downward inclined posture in which the tip of the slag auger does not interfere with the threshing machine or the like, and the tip of the slag is lowered below the horizontal. However, there are cases where it is dangerous to swivel during this downward tilt, so it is possible to swivel within a certain range even in a downward tilted posture, only when operating with a remote control panel that can be operated after confirming safety. It is a thing.
[0005]
[Means for Solving the Problems]
Under the above-described problems, the present invention extends the waste auger laterally from the side of the dredging tank so that the waste auger can be leveled from either a permanent operation panel that cannot be moved or a portable remote control panel. In the movable structure of the scouring auger in the threshing machine that enables posture change in the range of the posture and the upward inclined posture in which the tip is raised upward, and enables the turning in a certain turning range, the tip of the staking auger is In addition to being able to take a downward inclination posture that falls downward, the turning range is divided into a downward inclination posture prohibition range and a possible range, and in the operation with the permanent operation panel, downward inclination in the downward inclination posture possible range is possible. Further, the present invention provides a movable structure of the squeezing auger in a threshing machine in which turning is impossible and turning is also possible by operation with a remote control operation panel.
[0006]
By adopting the above means, the rejecting auger can be inclined downward within a certain range. Therefore, it is possible to perform safe and efficient picking regardless of the picking form. In addition, the operation in the downward inclined posture can be performed with either a permanent operation panel or a remote control operation panel, so that convenience is not impaired. On the other hand, if an attempt is made to turn the evacuation auger downward, depending on the permanent operation panel that is difficult to visually recognize the situation, this is impossible, so safety is ensured. However, with a remote control panel that can sufficiently check the situation, this is made possible and the convenience is further enhanced.
[0007]
Further, the present invention is such that a threshing machine having the above-described dredging tank is mounted on a combine, and a thresher is arranged on the left side in the advancing direction of the fuselage, and a dredging tank is arranged on the right side of the dredging auger. In this case, a means for setting the downward inclination posture prohibition range to a range that interferes with the dredger tank or the threshing machine when the rejection auger is inclined downward is provided. If a permanent operation panel and a remote control operation panel are provided together, a threshing machine such as a fixed harvester may be used, but when applied to such a mobile threshing machine, its advantage is It becomes even more prominent.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 5 is a plan view of a combine to which the present invention is applied, and FIG. 6 is a front view. The combine has a threshing machine 3 on the left side in the advancing direction on the chassis 2 on which the crawler 1 is suspended, and a front on the right side. The control unit 4 and the hail tank 5 are disposed from the front, and a pre-processing unit 6 for cutting and the like is provided in front of the chassis 2. The grain threshed by the threshing machine 3 is temporarily stored in the dredge tank 5, but is raised by the lifting auger 7 erected at the rear of the dredging tank 5, and then connected to the upper end of the lifting dredge auger 7. The discharged auger 8 is discharged out of the machine.
[0009]
In this case, the rejecting auger 8 is capable of turning in the horizontal direction around the axis of the lifting auger 7, and has a horizontal posture, an upward inclined posture in which the tip is raised above the horizontal, and a downward inclined posture in which it is lowered downward. Can be taken. 1 is a side view of the main part showing the structure of the posture change, and FIG. 2 is a partial cross-sectional side view. In short, the rejecting auger 8 can be rotated in a vertical plane with respect to the lifting auger 7. It has been pivotally attached to. In the case of this example, the drive frame 9 fixed to the discharge auger 8 is pivotally attached to the lifting auger 7 so as to be rotatable in the vertical plane, and the telescopic cylinder 10 is attached to the drive frame 9 and the lifting auger 7. The posture can be changed by the expansion and contraction of the telescopic cylinder 10.
[0010]
The telescopic cylinder 10 of this example has a drive unit 11 and an actuator 12 which are separated and housed in a drive frame 9 for protection. Then, the rear upper corner of the dredging tank 5 is cut out and the telescopic cylinder 10 is installed here to prevent interference and save space. In this case, when the slag auger 8 is set in a horizontal posture, the overall height is suppressed by setting the height so as not to interfere with the slag tank 5 and the threshing machine 3.
[0011]
FIG. 3 is a plan sectional view of the lifting auger 7 showing the swivel structure of the discharging auger 8. The lifting auger 7 is located in a horizontal plane with respect to a seat (not shown) fixedly provided on the chassis 2 or the like. The gear 13 is fitted in the middle (slightly lower position from the middle), the pinion 14 is engaged with the gear 13, and the pinion 14 is fixedly provided by a motor 15 that is also fixedly provided. It can be rotated by driving. As a result, if the motor 15 is driven, the lifting auger 7 rotates in the horizontal plane, and the discharge auger 8 also turns in accordance with this.
[0012]
As described above, if the telescopic cylinder 10 and the motor 15 are appropriately operated, the squeezing auger 8 can change its posture and turn, but this operation command is given by the permanent operation provided in the control unit 4. It can be performed from a remote control panel (not shown) provided for the remote control. In particular, the remote control panel is important for an assistant or the like on the ground to operate while confirming the work status. For this reason, this operation panel is temporarily locked to the tip of the waste auger 8, etc., and can be removed and used if necessary.
[0013]
By the way, there are certain restrictions on the posture change and turning of the evacuation auger 8 described above. First, regarding the posture change, there are three types of posture change: a horizontal posture, an upward inclined posture, and a downward inclined posture, and a free angle is set among them. However, it should not exceed the limits of an upwardly inclined posture inclined upwards of about 45 ° and a downward inclined posture inclined downwardly of about 15 °. For this reason, the detection piece 16 is attached to the drive frame 9 and the like, and a switch 17 for detecting this movement is attached to the lifting auger 7 to detect the limit. That is, when the switch 17 exceeds the operating angle α which is the limit of the upward inclination posture and the downward inclination posture, the telescopic cylinder 10 is disabled (FIG. 1).
[0014]
Next, as for turning, the evacuation auger 8 is located at a location where it is swung about 20 ° to the left from the front and rear lines of the aircraft, and is used with a evacuation auger mount (not shown). I take this when I am not doing it. The slag auger 8 can turn about 270 ° behind the threshing machine 3 and the slag tank 5 from this storage position, and can be set at any position. However, about 55 ° in the first half of this turning range turns above the straw tank 5 and the threshing machine 3, so in the present invention, this range is set as a downward inclination prohibited range (A) for prohibiting downward inclination, Let the remainder be a downward tiltable range (B) (FIG. 5).
[0015]
Therefore, it is necessary to detect which range the rejection auger 8 is currently in. Therefore, as shown in FIG. 3, three detection pieces 16 (a), (b), and (c) are attached to the outer periphery of the auger cylinder 18 of the lifting auger 7 (19 is a screw conveyor accommodated therein). They are mounted at different heights, and this is also detected by the three switches 17 (A), (B), and (C). In this case, the position to be detected is when the evacuation auger 8 is in the storage position, when it is at the boundary position between the downward inclination prohibited range and the downward inclination possible range, when it is at the turning limit position, etc. This can be determined by the combination of the detection piece and the switch.
[0016]
The above is the combination of the detection piece and the detection status of the switch. By arranging the three detection pieces and the switch so as to be in such a state, each position can be determined. Needless to say, a device for preventing the motor 15 from being driven further when the storage position is passed or the turning limit position is reached.
[0017]
In the present invention, in the horizontal posture or the upward inclined posture, the waste auger 8 can be turned from the storage position to the turning limit position, and at this time, the downward inclined posture is taken in the range where the waste auger 8 exists. This is configured so that it can be operated by a permanent operation panel or a remote control operation panel. However, in the operation with the permanent operation panel, the turning is not allowed even in the downward tiltable range (only the operation with the remote control operation panel can be performed). From the cockpit with the permanent operation panel, the situation of the evacuation auger 8 may not be sufficiently confirmed. Thus, the safety of the assistants and the like on the ground is ensured. FIG. 4 is a flowchart showing the procedure of this control. In short, if there is a turning command, the command from the remote control operation panel is confirmed even if the attitude of the evacuation auger 8 is confirmed and it is in the downward tiltable range. In this case, the motor 15 can be driven and turned.
[0018]
【The invention's effect】
As described above, according to the present invention, the squeezing auger can take a downward inclined posture within a certain range. Therefore, it is possible to perform safe and efficient staking regardless of the staking type. In addition, the operation in the downward inclined posture can be performed with either a permanent operation panel or a remote control operation panel, so that convenience is not impaired. On the other hand, if an attempt is made to turn the evacuation auger downward, depending on the permanent operation panel that is difficult to visually recognize the situation, this is impossible, so safety is ensured. However, the remote control operation panel that can sufficiently check the state makes this possible, so that the convenience is further enhanced.
