Description

[Detailed description of the invention] The present invention provides a sensor bar that can be displaced by contact with the planted stem culm at the front part of the reaping part, and works with the sensor bar that can be switched to multiple stages of transmission state. This relates to an automatic reaping/harvesting machine with an automatic clutch configured to link the operating section of the working section clutch to change the transmission state of the working section clutch in stages according to the amount of displacement of the sensor bar. By effectively utilizing the linkage structure between the and working part clutch,
Through simple structural improvements, the working part clutch can be configured to be operated manually, and the working part clutch can be easily switched by this manual operation.
The purpose is to enable accurate operation and to easily grasp the transmission state of the working part clutch due to manual operation.

First, an embodiment of the present invention will be explained based on a combine harvester with an automatic clutch shown in the drawings. device 8,
On one side of the planting grain culm introduction path 10 to the clipper type reaping device 9, the vertical axis X is
A sensor bar 3 is installed around the sensor bar 3, which can swing backward and automatically return when the contact is released.
By linking the working part clutch 2 interposed in the transmission system to the sensor bar 3, the sensor bar 3 swings backward.
The working part clutch 2 is disengaged and the working state changes from the operating state to the first engaging operating state in which power is transmitted only to the feed chain 11, and to the second engaging operating state in which power is transmitted to both the feed chain 11 and the reaping part 1. It is configured so that it can be switched automatically.

In other words, when the sensor bar 3 is not swung backward, the working part clutch 2 is in the cutting operation state, and the sensor bar 3
When the is swung backward to the first position, the working part clutch 2
switches to the first entry operating state, and the sensor bar 3
is further swung backward from the first position, and when it reaches the second position, it is configured to switch stepwise to the second entering operating state.

A human operating tool 4 is provided in the linkage mechanism between the sensor bar 3 and the working part clutch 2, and the working part clutch 2 can be controlled between the clutch disengaged state, the first engaged state, and the second engaged state by manual operation. It is configured so that it can be switched to three stages, including an on state and an operating state.

The operation linkage mechanism between the sensor bar 3 and the clutch 2 is such that a rotary body 13, which is interlocked and connected to the clutch 2 via a wire 12, is arranged concentrically in parallel with the sensor bar 3, and the rotary body 13 and the sensor bar 3 are connected to each other. A spring 14 is provided to bring the server 3 into pressure contact with the server 3,
Between the sensor bar 3 and the rotating body 13, when the sensor bar 3 swings within the range up to the second posture, the rotating body 1 is
3 is rotated to follow, and when the sensor bar 3 swings within the range after the second posture, only the sensor bar 3 is rotated independently while the rotating body 13 is held in the posture corresponding to the second entry operating state. A cam 15 is provided for swinging.

The human operating tool 4 presses the arm 16 connected to the rotating body 13 to swing the sensor bar 3 against the return force while allowing the sensor bar 3 to swing backward. The return posture of the sensor bar 3 is changed to the clutch disengagement operation posture that crosses the entry path 10 at right angles, and the first and second postures. This is a screw that presses against the
An operation handle 17 that is slidable in the diametrical direction is inserted and held so as not to come off.

According to the above configuration, by placing the sensor bar 3 in a posture across the transfer path via the human operating tool 4, the reaping section can be adjusted depending on the presence or absence of the transfer grain culm, that is, the grain culm to be harvested, during combine harvesting operation. 1 and the feed chain 11 can be automatically activated and deactivated, and by placing the sensor bar 3 in the first position, only the feed chain 11 can be activated,
A state in which the grain can be threshed by hand can be created, and by placing the sensor bar 3 in the second position, both the reaping section 1 and the feed chain 11 can be operated,
It is possible to create a state where inspection, etc. can be performed.

The protective cover 6 that covers the lateral outer side of the attachment base of the sensor bar 3 is provided with a handle 17 of the human operating tool 4 in the operating position corresponding to the three postures of the sensor bar 3. When the handle 17 is slid in the opposite direction, the handle 1 is inserted into a hole a which allows the non-removal preventing end 17a of the handle 17 to protrude laterally outward.
7 is moved and guided to a lower position where the handle 17 does not reach the hole a even if the handle 17 jumps upward due to vibration or the like, and by abutting and engaging with the protruding retaining end 17a of the handle 17. Locking holes 5 are formed to prevent the handle 17 from sliding laterally inwardly and to lock and hold the handle 17 in a state where the handle 17 is prevented from rotating. In addition, the hole a...
are arranged in series in the direction of operation movement of the human operating tool 4.

In the figure, 18 is a reaping unit lifting operation lever, 19, 1
Reference numeral 9 denotes a steering lever, and 20 denotes a threshing depth adjustment lever, which are arranged together at the rear of the threshing section 21.

Furthermore, the elevating mechanism for the reaping section 1 is configured to reversibly raise the reaping section 1 also by a steering operation.

In summary, the present invention provides the above-mentioned reaping and harvesting machine with an automatic clutch, in which a manual operating tool 4 for artificially displacing the sensor bar 3 is provided, and the working part clutch 2 is disposed on the basis of the operation of the manual operating tool 4.
A locking portion 5 for locking and holding the human operating tool 4 at a desired switching operation position is formed on the protective cover 6 for the mounting base of the sensor bar 3. characterized by something.

That is, it is simple to provide a human operating tool 4 for operating the sensor bar 3 by effectively utilizing the linkage structure between the working part clutch 2 and the sensor bar 3 without adding a separate operating structure to the working part clutch 2. By addition, the working part clutch 2 can be manually operated to operate the clutch in multiple stages, such as a clutch operating state for manual threshing work with the reaping part stopped, or a clutch operating state for maintenance and inspection in which the entire working part is operated. It is possible to switch to the clutch operating state, etc., and
By simply selectively engaging this manual operating tool 4 with the locking portion 5..., the sensor bar 3 can be easily and accurately operated to the desired clutch operating state, and the manual operating tool 4 can be locked. By watching Part 5...
The current state of clutch operation can be clearly seen at a glance. Moreover, the locking portion 5
... is formed on the protective cover 6 for the mounting base of the sensor bar 3, and is configured to serve both as the protective cover 6 and as a member for forming the locking part 5. Therefore, it is easy to operate the clutch by human operation, and the clutch can be operated easily. It has now been possible to construct a device having a locking portion 5 that allows the status to be grasped with a simple structure using a small number of parts.
