Description

[Detailed description of the invention] This invention includes a culm length detection sensor configured to swing when it comes into contact with the culm in the culm introduction path of the culm pulling device in order to control the handling depth, etc. Regarding the stem culm harvesting machine, regardless of the size of the stem culm,
The stem culm can be surely brought into contact with the sensor and transferred smoothly without causing problems such as sideways movement or clogging at the sensor installation part, and moreover, it is possible to move the stem culm forward from the sensor's lifting device. The purpose is to suppress the amount of protrusion as much as possible.

Next, embodiments of the present invention will be described based on illustrative drawings.

A threshing section 2 is mounted on a crawler type traveling machine stand 1, and as the machine travels, a pre-harvesting section is provided which raises and reaps planted grain culms and supplies the reaped grain culms to the starting end of the threshing section 2. It is connected to the front part of the traveling machine base 1 to form a combine harvester.

In the reaping pre-processing section, the clamping and conveying device 5 that feeds the grain culm from the reaping device 3 to the threshing feed chain 4 is configured to be able to swing up and down around the axis P on the conveyance end side. By swinging operation,
The gripping position of the grain culm from the reaping device 3 can be changed in the direction of the culm, and the handling depth in the threshing section 2 can be changed.

In the pre-harvesting processing section, as shown in FIGS. 2 and 3, a sensor bar 6 configured to swing by contact with the grain culm and a switch mechanism 7 interlocked with this sensor bar 6 are respectively installed. Two of the provided culm length detection sensors 8a and 8b are arranged so that the sensor bar 6 is located at the same level to detect the same culm length to form a sensor group, and the three sensors in this sensor group are , a pair of left and right grain culm pulling devices 9, 9 are raised in the grain culm introducing path A and are arranged in parallel in the culm direction of the grain culm, and a pair of left and right sensors 8 in each of the sensor groups.
a, 8b are distributed and arranged on both the left and right sides of the grain culm introduction path A, and in each of the sensor groups, both the left and right sensors 8a, 8b are connected to the orr mechanism 1.
0, and each of the orer mechanisms 10 is configured to determine that the sensor group has entered the detection state by knowing that either of the left and right switch mechanisms 7, 7 has entered the on state. , a culm length detection device for the raised grain culm is constructed. That is, by knowing that the orer mechanisms 10 corresponding to both the middle and lower sensor groups are in the sensor detection state judgment state, the grain culm length is determined to be the standard, and all the orer mechanisms 10 corresponding to all sensor groups are in the sensor detection state. By knowing that the grain culm is in the detection state judgment state, the grain culm is longer than the standard, and the orr mechanism 10 corresponding only to the lower sensor group is in the sensor detection state judgment state, or all the sensors By knowing that the orr mechanism 10 for the group is in the sensor non-detection state, it is configured to judge that the grain culm is shorter than the standard, and even if the grain culm amount is small, the grain culm is detected by the sensor. sensor 8 without moving laterally in the installation section.
Make sure to contact a or 8b, and
Even if the amount of grain culms increases, the left and right sensors 8
Both a and 8b are configured so that they are not swung by the grain culm pressing force and become a resistance to the moving grain culm, and the space required in the grain culm movement direction to enable sensor rocking is minimized. It is configured so that

The cover 11 shown in FIGS. 1 to 3 is intended to prevent grain culms from getting caught in the switch mechanism 7 and the mounting portions of the sensors 8a and 8b on the lifting device 9.

As shown in FIG. 2, the clamping and conveying device 5 is configured to be swingable by an electric motor M and a swinging member 12 interlocked with the electric motor M, and the operating amount of the swinging member 12 is Based on the detection result of the device 13 that detects the swinging position of the clamping and conveying device 5, and each orer mechanism 10 of the culm length detection device.
A controller 14 for automatically driving and stopping the motor M based on the information from ... is installed in the main body of the machine, and the handling depth is automatically adjusted based on the culm length of the grain culm to be lifted. It is structured so that work can be done while making changes and adjustments.

The present invention can also be applied to various types of stem and culm harvesting machines, such as a binder configured so that the binding position is automatically changed and adjusted based on culm length detection, and whose work type is different from that of a combine harvester.

In summary, in the above-mentioned stem culm harvester, the present invention has two sensors 8a and 8b installed in the stem culm introduction path A in order to detect the same culm length when the culm length detection sensors 8a and 8b are installed. It is characterized in that the same culm length detection sensors 8a and 8b are arranged on both the left and right sides and are linked to the orr mechanism 10.

In other words, according to the above configuration, even if the amount of stem culms is small, the stem culms can be easily removed, as in the case where sensors and guides for guiding the grain culms are distributed on both the left and right sides of the stem culm introduction route A. The stem will not be moved laterally by contact with the guide, and will surely contact either the left or right sensor 8a or 8b, and even if the amount of stem culm increases,
Both the left and right sensors 8a, 8b are swung by the pressing force of the grain culm, and unlike the guide, the resistance to the moving stalk does not increase significantly. Therefore, whether the amount of stem culms is large or small, it is possible to reliably bring the stem culm into contact with the sensor 8a or 8b, and the culm length can be reliably detected. It is now possible to transport stem culms in an orderly and smooth manner without causing troubles such as disturbed transport posture or clogging due to movement or movement resistance, and subsequent processing of stem culms can be carried out smoothly. Ta.

In addition, since the sensors 8a and 8b are of two types, one on the left and one on the left, compared to the single type which is long and extends from one end of the introduction path A to the other, it is necessary to enable the sensor to swing. Since the space in the direction of movement of the stem culm can be reduced, the sensor can be arranged advantageously in terms of preventing problems such as protruding forward from the lifting device 9 and causing the stem culm to become easily caught.
