Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is configured to transport the reaped husk culm in a standing position through the locking pawl rotation location and with the ear end side being locked and conveyed toward the threshing section. , relating to a combine harvester configured such that the culm is transferred outside of the conveying device at the rotation point of the locking claw, and that changing and adjusting the handling depth at the rotation point of the locking claw is performed by manual operation. .

This type of combine is designed to be as simple as possible,
Conventionally, the culm length of the conveyor culm has been determined by visual measurement, and the handling depth has been set or adjusted based on that judgment, but all of this has been left to human judgment, and the handling depth Settings and adjustments are uncertain, causing problems such as leaving unhandled grains and unnecessarily increasing the threshing load.

In view of the above points, the present invention provides the above-mentioned type of combine harvester with the setting and adjustment of handling depth based on appropriate culm length detection without significantly impairing the premise of simplifying the configuration by adding a simple structure. In addition, it is possible to accurately detect whether the setting and adjustment of the handling depth is appropriate automatically and by effectively utilizing the conveyance characteristics, even though it is caused by manual operation. The purpose is to enable accurate setting and adjustment of the handling depth.

5 is connected to the support shaft 19 so as to be movable only in the axial direction thereof, and the lever 15 is always biased toward the guide plate 16 via the compression spring 21, so that when the lever 15 is operated, , and is configured so that the level of laxity can be changed and fixed in five levels.

Limit switches S1, S2, . S3
．． S4. In addition to providing S5, a corresponding lamp L is provided.
1. L2. L3. L4. A circuit C (not shown) with interposed lamp L5 is connected in series with each other, and the lamp L1. L
22 R3t R4 and R5 are rotated to the outside of the transport start end of the vertical transport section i, the locking claw 22 of the ear-side locking and transporting device 11, and the rotating location, as shown in FIGS. 2 and 4. Guide walls 23K are provided to guide the moving shell culm, and are installed upward along the culm direction at predetermined intervals. The structure is such that the height can be easily set or adjusted by visual measurement.

The lamp L1 of the guide plate 16 is located slightly behind the lamp L1 near the mounting position, and along the culm direction at the location where the locking pawl 22 of the ear side locking and conveying device 11 rotates. In addition, a starting sensor R is installed at a slightly upper part of the tip side locking and conveying device 11 when viewed from the side, and a swing sensor R1j R is installed at a location corresponding to the third lamp L3 and the fifth lamp L5, respectively.
2, and switches M 2 T 1 and T that act on the sensors R2R1 and R2, respectively, in accordance with the rocking motion.
2 is attached.

As shown in FIG. 5, the switch M for the activation sensor R is configured as a normally open main switch, and the alarm device 2
4 is connected in series with the sensor switch T1. T2 is configured as a C-contact type, and the contacts are configured to be interposed in circuits connected in parallel to the circuit C at different positions from each other,
Depending on the position of the lever 15, the sensor switch T0. T
2 is automatically switched to detect the upper limit or lower limit of the straightness, and when the culm contacts the starting sensor R, the circuit C is closed, and in this state, the culm contacts the rocking sensors R1 and R2. The alarm device 24 is activated to prompt the user to adjust the degree of withdrawal when the state or non-contact state is reached.

Next, an example will be shown and explained in detail.

Now, assuming that the lever 15 is fixed at a position corresponding to the third limit switch 53vc by visual measurement based on the relative position between the tip of the culm and the lamp, as a result, the first sensor R1 detects the lower limit and the second sensor R2 detects the upper limit. It has the following functions.

Then, when the culm length becomes short and comes off the first sensor R1, an alarm sounds.

Based on this, the removal distance is changed from the relative position to the lamp to a position corresponding to the first or second limit switch S1, 52VC by operating the lever 15.

As a result, the circuit automatically switches, and the first sensor R
1 has the function of detecting the upper limit.

In order to detect the adjustment state of the removal depth, the adjustment state of the handling depth is not limited to the one in which a limit switch S1 is provided at the locking position of the adjustment lever 15. Various structures such as the above can be adopted, and these structures are collectively referred to as the detection mechanism 25.

The standard for visually measuring the culm length of the shell culm is not limited to the one in which the lamp L1 can be freely switched between the lighting state and the non-lighting state as in the above embodiment, but also the guide wall 2.
Various structures can be adopted, such as a display board that is rotatable and has parts of the same color and parts of a different color as in 3, and is configured so that only the corresponding part exposes the different color part as the handling depth changes. These marks are collectively referred to as markers 26.

In addition, it is not limited to the case where a plurality of these markers 26 are provided and the vertical position is changed by the circuit configuration as in the above-mentioned embodiment, but one marker 26 can be configured to be vertically slidable and can be automatically adjusted according to the change in handling depth. Alternatively, the vertical position may be changed or fixed, and these are collectively referred to as a switching mechanism 27.

In the case of the sensors R1 and R2, instead of switching between upper limit detection and lower limit detection as in the above embodiment, for example, both sensors R1 and R2 are supported by one bracket, and this bracket The vertical position may be automatically changed and fixed according to changes in the handling depth.

In summary, the present invention provides the above-mentioned combine harvester with a mechanism λj for detecting the handling depth adjustment state, and
A marker 26, which serves as a standard for visually measuring the culm length, is arranged outside the transfer shell culm at the rotation point of the locking claw 22, and the handling depth is adjusted based on the detection result of the detection mechanism. In order to visually detect the passing position of the tip of the culm (adapted to the state) by the marker 26Vc, a mechanism 27 is provided that automatically switches the vertical position of the marker portion to be used as a reference, and the locking claw 2
2. Sensor R that detects and notifies the presence of a culm with a length outside the appropriate culm length range outside the transferred culm at the rotation point.
1. R2 is provided, and the detection position by the sensors R1 and R2 is configured to be automatically changed in conjunction with the change in the handling depth in order to adapt to the handling depth adjustment state. .

In other words, the marker 26 can be automatically switched up and down in accordance with changes in the handling depth so that the position where the tip of the culm should pass can be visually determined in each state where the handling depth is changed and adjusted. By providing the marker 26 at the tip of the culm, it becomes possible to visually and reliably and easily judge the predetermined handling depth based on the relative position of the marker 26 and the tip of the culm, and also to prevent the length of the culm that is outside the appropriate culm length range based on the adjustment state of the handling depth. By installing sensors R□ and R2 to detect and notify the presence of the culm, it is possible to reliably detect even if the handling depth is set incorrectly or if the handling depth changes during work. Overall, it has become possible to set and adjust the handling depth with extremely high accuracy.

Moreover, as the locking claws 22... rotate, the culm is swung around by centrifugal force, and the culm is pressed against and stretched by a member that guides the rotation of the culm. Since the marker 26 and the sensors R1 and R2 are provided outside the culm at the moving point, the appropriate culm length can be measured and detected visually, and the sensors R and R2 can be reliably activated by pressure contact, thereby increasing the handling depth. The settings and adjustments can now be made with even greater precision.
