Description

[Detailed description of the invention] The unexploded IJ is a method for handling combine harvesters that changes the height of the threshing process by changing the depth of the threshing process. Regarding the depth control tIi device + ttk.

Since IIE, in the depth of 1 section by Tanabata, the emergency + dynamic operation command / r'tJ function by the operation lever has been added, and 1b,
In the event of a failure in the air circuit or motor, it is possible to perform manual adjustment with one operation button even if the air circuit or motor is broken.

According to No.-109031 and JP-A-54-9J425
I don't know.

However, since the first two motors have a screw shaft that is rotated in the opposite direction and is supported and guided by balls, there are the following problems.

■The screw shaft needs to be manufactured and supported to prevent it from swinging around, which increases processing and processing costs and complicates the equipment.

(22) It is still necessary to press the ball (A) with a strong force to prevent the ball from coming off while the shaft is rotating, and the combine harvester's reaping experience: ':: 4'+; Occurs during operation - Fine dust and the like can clog the ball and prevent the spiral shaft from working properly.

■Furthermore, the hole is pushed 1'L by a strong force, and #llll IIB etc. enter the hole part, so when there is an emergency adjustment or a malfunction of the mountain circuit, I want to be able to do it quickly with dynamic operation and 1J removal.

~Force,) 1. Things after 3 Bonds: Hey 1, the motor r (because the operating lever is locked between the teeth of the 1 inch 1 wheel that is rotated in the forward and reverse directions).1. (During an emergency adjustment in which the operation lever is moved while the gear is being rotated by the remoter, the lock pin must be removed from the space between the teeth and moved between the other teeth of the rotating gear.) If this cannot be done quickly, the operator must keep the handle in place.However, if the emergency adjustment is to be made narrower, it may be necessary to use a field with significant changes in culm length, a field with many lodging culms, or a field with many weeds. During mowing and threshing operations such as mowing and threshing, there is one thing that happens when the driver is driving, shouting "ψ" while shifting gears, and other operations are often required. There is one thing that I can't concentrate on.

In order to obtain a constant depth adjustment amount, a complicated control circuit is also required.

The present invention enables emergency manual firing operation using the operation lever even when the depth of handling is insufficient due to the power of a motor etc.
In addition, in the event of a failure of the 1st distribution force, 1 is also operated by the ladder lever (N) Jnorυlj ffi, and the combined harvester's handling depth that eliminates all the drawbacks of the slope 14-joint device H ! The purpose is to provide.
