Description

[Detailed explanation of the idea] The present invention relates to a combine harvester.

In recent years, this type of combine harvester automatically stops the traveling device if the planted culm is absent for a certain period of time, or when there is no treated culm in the working equipment such as the threshing device. It has been considered to automatically stop the traveling device and the working device in a timely manner in conjunction with the absence of a culm, such as automatically stopping the working device.

This is because, in the case of an operator on board, the required operation by the operator at the end of the work is reduced, and also because it is highly usable as an effective means for constructing an unmanned combine harvester.

The purpose of the present invention is to provide a combine harvester that can perform efficient work with an excellent control mechanism.

The characteristic structure of the combine harvester according to the present invention is that a grain processing equipment section is provided with a shell culm presence/absence detection sensor for stopping the traveling device when the presence or absence of the shell culm is detected for a certain period of time, and after stopping the traveling device, This configuration is advantageous in that it is provided with a time control mechanism that sequentially stops the vertical conveyance device and the husk conveyance device such as the feed chain after a certain period of time, and further stops the threshing device section by cutting off the driving force of the engine after a certain period of time. It produces the following effects.

That is, the culm presence/absence detection sensor detects the end of the supply of husk to the threshing device, and the traveling device and the husk processing system in the threshing device are sequentially stopped. Only one is required, the control system can be simplified, and the machine can easily start running again, making it extremely effective for constructing an unmanned combine harvester.

In addition, various devices related to husk processing, such as threshing equipment, are sequentially stopped during the husk conveyance path such as the traveling device, vertical conveyance device, and feed chain, from the front process to the post-process after the harvested husk culm is finished. The entire combine can be operated more efficiently.

Furthermore, when carrying threshed grain out of the machine from the combine, even if the operator leaves the cockpit immediately after the machine stops after cutting a row of planted shell culms, the shell culms inside the machine are After the threshing process continues to some extent automatically, the culm processing system including the threshing device is stopped, so when starting the combine operation again, the starting load is small, and the engine does not need to be started each time. Even if the process is not completed, the processing system for the shell culms is simply stopped, so rework can proceed smoothly.

Embodiments of the present invention will be described in detail below based on the drawings.

The figure shows a combine harvester in which a threshing device 2 is mounted on a crawler traveling device 1, and a reaping pre-processing section 3 is connected to the front part of the machine.

The husk culms raised and cut by the lifting and reaping section 4 consisting of the blade 1 pre-processing section 3, the lifting device 4a, the reaping device 4b, etc. are transferred to the side of the threshing device 2 by the vertical conveyance device 5. It is configured to be delivered to a feed chain 6 installed on the side.

One of the planted culm lifting paths A, A formed along the lateral side of the lifting device 4a is normally provided with a path A.
A culm presence/absence sensing sensor 7 is provided in a state in which it is pivoted to the vertical axis X and the circumference 9 so as to be swingable.

When this sensor 7 swings backward by a certain amount or more due to contact with the culm, the electric switch 8 is configured to be activated by contact. The structure is such that the presence of a shell culm is detected, and the absence of a planted shell culm is detected by deactivating the electric switch 8.

The signal from the electric switch 8 is input to the first timer circuit 9, as shown in FIG. It is configured to operate an electromagnetic clutch 10 for driving that turns transmission on and off, and a second timer circuit 11 as a time control mechanism.

The running electromagnetic clutch 10 is configured to be switched from a clutch engaged state to a disengaged state when an activation signal is input, and the second timer circuit 11 is configured to switch from a clutch engaged state to a disengaged state in response to input of an activation signal, and the second timer circuit 11 is configured to switch from a clutch engaged state to a disengaged state in response to input of an activation signal. 6
A time limit is set so that the clutch of the culm conveying device such as the above is disengaged, and the transmission clutch of the second part of the threshing device is disengaged to stop the second part of the threshing device after a certain period of time after which the threshing process is surely completed.

According to the above configuration, when the machine body is running for reaping, when the planted culm runs out at the end of the work, the crawler traveling device 1 is automatically stopped after the first certain period of time, and after the next certain period of time, the crawler traveling device 1 is vertically stopped. The conveying devices such as the conveying device 5 and the feed chain 6 are stopped, and the second part of the threshing device is automatically stopped after a certain period of time.

Incidentally, the shell culm presence/absence detection sensor 7 may be provided in the shell culm conveyance path conveyed by the vertical conveyance device 5 or the feed chain 6 to detect the presence or absence of the shell culm. The culm presence/absence sensor 7 may be configured to indirectly sense the presence or absence of a culm based on an increase/decrease in the load or rotational speed of the handling cylinder.

In these cases, the detection of the absence of the culm is delayed compared to when the sensor 7 is raised and placed in the path A as in the embodiment, so it is sufficient to set the control time of the time control mechanism 11 to be shorter by the delay time. Furthermore, in the case of detecting a handling torso load with a sufficient delay time, the traveling device 1 may be stopped immediately upon detection of the absence, without using the first timer circuit 9 in the embodiment.

It is preferable that the fixed time period for detecting the absence of a culm be freely adjustable, for example by making it possible to change the setting time of the first timer circuit 9 in the case of the embodiment. The optimum time can be set according to the speed change and work conditions based on the shape, size, softness, etc. of the field.

Further, this fixed time period may be changed automatically in conjunction with the change in traveling speed.
