Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a contact type culm length detection device in a planted grain culm lifting device, and uses information from the culm length detection device to ensure that the handling depth is within a set range. A handling depth control mechanism that automatically operates the handling depth adjustment device based on the pre-harvesting treatment section is provided, and a device is installed to detect the presence or absence of grain culms in the pre-harvesting processing section. The present invention relates to a depth control device for a combine harvester, which includes an automatic control switching mechanism that enables the control device to be operated by a depth control mechanism.

In the above combine harvester, conventionally, work f! : At the beginning of the process, or when the machine direction was changed and work resumed, troubles such as an abnormal increase in the threshing load due to heavy handling could occur.

This is because when starting work or restarting after changing the orientation of the machine, the machine is generally moved forward at low speed to align itself with the planted grain culm rows, and the planted grain culms are raised in relatively small amounts. The tip side of the 4tjR general culm, where the culm length detection device acts, is weak and bends easily, and in the case of a contact-type culm length detection device, the culm-to-grain contact member is Since it is biased to restore to the non-contact position, the tip side of the grain culm that is exposed to the pulling device is pushed forward by the culm length detection device, and the grain culm side of the grain culm is pushed forward by the culm length detection device. The upper one of the contact members t passes through without being displaced to the grain culm contact position, and the presence/absence detection device enters a predetermined presence detection state. It is very similar to A!ll, which causes the culm to be incorrectly detected as a short culm.Also, while the machine is running at low speed, the handling depth adjustment device may not be operated to the deep handling side.
This is because the insertion depth of the grain culm into the handling chamber is longer than the actual culm length.

An object of the present invention is to make it possible to prevent troubles caused by the above-mentioned erroneous detection at the start of work 119 without requiring any special effort.

The characteristic configuration of the present invention is that, in the above-mentioned container handling depth control device, a device for detecting whether the forward speed is below a set value is provided, and the An automatic restraint system S that disables the operation of the nIJ adjustment device by the rear V-shaped control mechanism regardless of the information from the presence/absence detection device only when the forward speed is below the set value. -It's a matter of fact.

In other words, by setting the automatic check mechanism to the low speed at which the machine travels for positioning with respect to the planting culm row, the handling depth can be adjusted during positioning travel. It is completely possible to prevent the device from being operated unequally due to incorrect culm length detection, and the handling depth is maintained accurately at pronation regardless of whether or not the traveling speed at the start of work is slowed down. I was able to.

Moreover, since the controlled stop is performed automatically, there is no special effort required to turn off the main switch, which is advantageous in terms of operation.

By the way, in order to completely prevent the above-mentioned troubles from occurring at the start of work, a set of timers must be set so that the timer is controlled and stopped from the time the aircraft is launched until the time force S estimated to be required for the alignment has elapsed. A mechanism may be provided, but in this case, the aircraft is decelerated before stopping at the end of the grain culm row, and at fc, the measured time has already passed and a controlled stop is not performed. It is accompanied by @ while troubles similar to those that previously occurred at the beginning of work occur. On the other hand, in the present invention, since the controlled stop is performed based on speed detection, the controlled stop can be performed reliably at any location such as the end of the working culm row, and the above-mentioned problem can also be solved. .

As a result, the handling depth can be accurately maintained within the set range regardless of the traveling speed.
