Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a threshing grain storage tank with a vertical feed transfer device for lifting the grains in this tank, and at the upper end of this vertical feed transfer device, The present invention relates to a combine grain carrying-out device in which a lateral feeding conveying device for laterally feeding grains is continuously connected so as to be rotatable around a vertical axis and to be undulated and swingable around a horizontal axis.

[Conventional technology]

In the case of using the conventional grain carrying-out device, when the grain carrying-out by the vertical feeding carrying device and the lateral feeding carrying device is completed, the operator stops the operation of both the carrying devices by a clutch or the like, and then the turning position of the lateral feeding carrying device and While observing the undulating position, the moving operation from the carry-out position to the storage position of the carrying device is performed.

[Problems to be solved by the invention]

In the case of the above-described conventional grain unloading device, there are the following problems and there is room for improvement.

That is, there is a problem in that the operator cannot perform other work while the operation of moving the lateral transporting device from the unloading position to the storing position is being performed even after the grain unloading is completed. Further, the moving operation is considerably difficult for an inexperienced worker, and is one of inefficient operations.

Then, as means for solving the above-mentioned drawbacks, Japanese Patent Laid-Open No. 61-
As disclosed in Japanese Patent No. 227708, a grain sensor is provided near the grain discharge screw at the bottom of the tank, and when the grain sensor detects that the inside of the tank has become empty as the grain is discharged, It is conceivable to automatically store the transverse transport device based on the detection result.
When detecting the flow of the grain at the grain discharge screw at the bottom of the tank and automatically storing the transverse feed transport device, the grain is bridged across the both side walls of the tank at the top of the grain discharge screw. If the grain is temporarily not transported due to the bridge phenomenon, there is a problem that the transverse transport device is automatically stored.

An object of the present invention is to provide a combine grain unloading device capable of solving such a problem.

[Means for solving problems]

The characteristic configuration of the present invention for achieving the above-mentioned object is to provide a detecting means for detecting a stop operation of a tank clutch lever which controls the driving and stopping of the grain carrying-out operation of the vertical feeding conveying device and the horizontal feeding conveying device. The control means is provided for starting the control of the swinging and undulating swing of the transverse transport device to the storage position based on the detection signal from the detection means, and the operation and effect are as follows.

[Action]

When the tank clutch lever is disengaged with the completion of the discharge of the grains, the detection means detects the disengagement operation of the tank clutch lever, and based on the detection signal, the movement control of the transverse feeding device is performed by the control means. It starts automatically.

[Effect of device]

Therefore, the worker can immediately carry out the next work after the completion of the grain carrying-out by both of the above-mentioned transporting devices, specifically the work of loading the combine to move the whole combine to the next work place. Efficiency is greatly improved. Further, it is not necessary to move the lateral-feeding carry-out device, which had to be performed while visually observing the turning position and the undulating position of the lateral-feeding conveying device, and a series of operations can be easily performed by an unskilled worker.

Since the end of the grain discharge is performed by detecting the disengagement operation of the tank clutch lever, the end of the grain discharge is performed by detecting the flow of the grain by the grain discharge screw at the bottom of the tank. In addition, when the grain temporarily bridges at the upper part of the grain discharge screw and the grain is temporarily not transported, the transverse feeding device is not automatically stored unexpectedly. .

In addition, the storage can be started automatically by turning off the tank clutch lever without the need for a separate storage operation switch.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 4 and 5, the crawler traveling device (1)
The threshing device (2) is attached to the machine frame equipped with
And a tank (3) for storing threshing grains from now on are mounted side by side in a lateral direction, and a mowing unit (4) that can be raised and lowered is continuously provided at the front part of the machine frame, and is a combine harvester that is an example of a moving thresher. Make up.

The device for taking out the grains in the tank (3) is equipped with a vertical feed transfer device (5) for lifting the grains in the tank (3) upward at the rear part of the tank (3), and this vertical feed transfer device ( At the upper end of (5), install the horizontal feed transport device (6) that transports the grain from now on.
It is configured so as to be rotatable around it and to be capable of undulating and swinging around a lateral axis (b). In addition, as shown in FIG. 2, the specific means for turning the lateral feed conveying device (6) is a pinion gear (13) rotationally driven by an electric motor (11) and an articulation between the pinion gear (13). A means for using a ring gear (15) that is interlocked and that swings integrally with the lateral feed screw conveyor (6).
The specific means for tilting and swinging (6) is the hydraulic cylinder (1
It is a means of using 7).

Further, as shown in FIG. 1, driving and stopping of the grain carrying-out operation of the vertical feeding transporting device (5) and the horizontal feeding transporting device (6) are performed as follows.
Tank clutch lever (1 that can be operated from the driver's seat (10)
8) is operated by a limit switch (20) near the tank clutch lever (18), which is operated by being pushed by the tank clutch lever (18) in the stopped position. ) In other words, a detection means (20) for detecting the stop of the grain carrying-out operation is arranged.
Then, the signal from the detection means (20) is adapted to be input to the controller (19) which is a control means for starting the control of the turning and the oscillating swing of the transverse feed conveying device (6) to the storage position. There is.

It should be noted that the limit switch (21), (2
The signal of 2) is also input to the controller (19) and performed. That is, by the operation piece (15a) provided on the side of the ring gear (15), the limit switch (21) that is operated by being pushed in a state in which the transverse feed conveying device (6) is rotated to the storage position, and the threshing. Underframe (8) on top of device (2)
A limit switch (22) provided upward at an appropriate position of a receiving tool (7) for receiving and placing and supporting the lateral feed conveying device (6), which is attached via the limiting tool (22). A signal of a limit switch (22) which is pressed and operated in a state of receiving the lateral feed conveying device (6) which is undulated and rocked in 7) is inputted to the controller. Then, based on the signal from the limit switch (21), the turning of the lateral feed conveying device (6) is finished, and the undulating swing of the device (6) is started. Further, based on the signal from the limit switch (22), the up-and-down swing of the lateral feed conveying device (6) is completed, and the fixing mechanism (9) for fixing the device (6) in the retracted position is activated. It's set to start.

In the combine grain carrying-out device having such a configuration, the stop of the grain carrying-out operation by the both carrying devices (5), (6) is automatically detected by the detecting means (20), and the detection signal Based on this, the movement control of the lateral transporting device (6) is automatically started by the control means (19).
