Description

DETAILED DESCRIPTION OF THE INVENTION The present invention detects the presence or absence of a group of collected waste straw released into a field or a grain storage bag, and establishes a desired mechanism for release based on the detection operation. A sensor is installed to activate the collected waste straw or grain collection bags, so that the collected waste straw or grain collection bags can be released in a well-organized manner into the field so that the subsequent collection work for the released waste straw group or the released grain storage bag can be carried out rationally. The present invention relates to a technique for attaching the sensor to the reaping/harvesting machine.

With this type of reaping harvester, when moving around the headland at the edge of the field, the headland is rougher than other parts of the field, so
If the machine tilts, even if the height of the sensor above the ground is set as high as possible, it may accidentally touch the ground against a stump, stone, ridge, or ground. This tends to lead to erroneous detection operations due to
Moreover, the sensor is likely to be deformed or damaged.

This is contrary to the purpose of streamlining the subsequent collection work by discharging the collected waste straw or grain storage bags in a well-organized manner in the field.

In view of this, an object of the present invention is to prevent erroneous detection operations associated with machine rotation on the headland at the edge of a field, and at the same time to ensure safety for the sensor.

The reaping harvester according to the present invention, as described at the beginning, is provided with a mechanism for raising and retracting the sensor to a non-detection height position in conjunction with the disengaging operation of the steering clutch or the raising operation of the reaping section. It is characterized by

That is, according to the present invention, the sensor can be automatically activated by simply disengaging the steering clutch or raising the reaping section by the operator simply performing the necessary operations to turn the machine around the headland. Since the machine can be raised to a non-detection height position and evacuated, it is possible to remove stumps, stones, etc. caused by the tilting of the machine while turning on headlands.
It is possible to reliably prevent erroneous detection operations caused by the sensor coming into contact with the ground, etc.

Therefore, the present invention can prevent the accidental release of collected waste straw or grain storage bags due to erroneous detection when moving around the headland, and at the same time prevent deformation caused by the contact of the sensor with stump stones, the ground, etc. It has now been possible to provide a reaping harvester that can prevent breakage and release collected waste straw or grain storage bags to the field so as to streamline subsequent collection work.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on a combine harvester (an example of a reaping harvester).

The combine harvester includes a reaping section 4 that can be raised and lowered via a hydraulic cylinder 5, a threshing section 6, a crawler running section 7, and a riding section 8. The present invention is equipped with an automatic bagging section 11 that automatically packs the grain taken out from the threshing section 6 into bags via the threshing section 6, and a waste straw binding device 21 that binds a group of waste straw from the threshing section 6 at the rear of the threshing section 6. The grain storage bags 10 from the automatic bagging section 11 are intermittently placed on the outside of the machine 2 along the row direction during harvesting in the circular cutting mode as shown in Fig. 6. When harvesting a plurality of bundles of straw from the mechanism 12 and the bundling section 21, the machine 2

Grain storage bag 1 released into the field
0, the presence of the ejection mechanism 12, 2 is detected by contacting the lateral side of the ejection mechanism 12, 2.
Sensor 1 which acts to operate 2 at the same time is connected to this machine 2.
It is extended and supported laterally and outwardly. The automatic bagging section 1
1 is capable of sequentially taking out a plurality of grain storage bags 10 stacked laterally with their openings facing upward, starting from the one located on the lateral outer side. A pair of bag hanging support rods 13, 13 and a bag mounting stand 1 that support the bag in the state
4, and by rotating a group of grain discharge tubes 15 arranged at intervals around the longitudinal axis in a pair around the longitudinal axis. , the discharge cylinder 15 . 10 is moved to the bagging position to supply grain into the bag 10, and at the same time, the discharge tube 15 is moved from the grain discharge position to the non-operating position, and the bag 10 containing the grain is moved laterally outward. mechanism 16 and detecting that the bag 10 is filled with grains. A fullness detector 17 for intermittently rotating the discharge cylinders 15... is provided. The bag release mechanism 12 includes a pair of bag suspension support rods 13, 13 and a mounting table 1.
4 extend laterally outward and diagonally downward, and the grains slide with their own weight from the bagging position while being supported by the extended length support rod portions 13a, 13a and the extended loading table portion 14a. The extended support rod portions 13a, 13 of the storage bag 10 are in contact with the upper and lower ends of the storage bag 10.
Stoppers 18, 18 are provided that can be freely switched between a state of preventing the product from falling off laterally outwardly from the extended mounting table portion 14a and a state of releasing the contact and allowing the product to fall off. Solenoid 1 that switches between two states
9 and 19 are provided.

The bundled waste straw discharge mechanism 22 is disclosed in Japanese Patent Application No. 52-72396.
As described in the issue, the dropper 23 that receives the bundled waste straw is biased via a spring so as to maintain the receiving posture at all times, and the dropper 23 is swung by the weight of the bundle of waste straw and is placed there. It is configured to discharge the placed waste straw bundle.

A stopper is provided at one end of the dropper 23 and is always biased toward the projecting side, and a solenoid is attached to the stopper so that the dropper 23 can be switched between a state of preventing and a state of permitting swinging of the dropper 23 due to egress and retraction. , the stopper is retired by excitation of the solenoid, and the dropper 23 is allowed to swing.

The sensor 1 has a support rod 1A that protrudes laterally outwardly supported by the machine 2 so as to be rotatable around the lateral axis, and a contact member 1B that can come into contact with the discharge bag 10 on the support rod 1A. springs 1C, 1C, which are attached to the support rods such that they can be freely changed in position and fixed in a rotational manner in the longitudinal direction of the support rods;
As the contact member 1B comes into contact with the discharge bag 10, the support rod 1A
When the rotation exceeds a certain level, the bag release mechanism 12 is operated to close.
