Description

Detailed Description of the Invention The present invention provides a sensor that detects the presence or absence of a group of collected waste straw released into a field or a grain storage bag released into an open field, and a sensor that detects the presence or absence of a group of collected waste straw released into a field or a grain storage bag released into an open field. and a mechanism for discharging the grain storage bag, and configured to operate the mechanism for discharging the group of focused straw or the mechanism for discharging the grain storage bag, or both based on the detection operation of the sensor, Furthermore, the sensor is extended and supported laterally and outwardly of the machine, so that the waste straw group or the grain storage bag is discharged in a well-organized manner into the molding area, thereby streamlining the subsequent waste collection work. The present invention relates to a reaping harvester equipped with a sensor for detecting field discharged substances such as a combine harvester.

A problem with reaping and harvesting machines that is likely to cause running problems and damage to the ejected material due to the machine moving backwards during harvesting on the headland, causing the ejected material to be accidentally stepped on or caught on the machine body. It was hot.

An object of the present invention is to solve the above-mentioned problems by effectively utilizing the above-mentioned sensor and by making simple structural improvements.

The reaping harvester with a sensor for detecting field emissions according to the present invention has the following features:
The device described at the beginning is characterized by being provided with a device that automatically stops the aircraft or issues an alarm for stopping when the sensor encounters the ejected object and performs a detection operation when the aircraft is moving backward. do.

That is, according to the present invention, when the aircraft is reversing, if there is an ejected object on the planned backward path, the ejected object can be detected before it is stepped on or caught. Can stop the aircraft.

Therefore, the present invention prevents running obstructions, damage to ejected materials, etc. when the aircraft moves backwards, and as a whole allows subsequent ejected material recovery work to be carried out safely and rationally. Therefore, we have been able to provide a reaping harvester with a simple structure and a sensor for detecting field emissions. 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 includes a reaping section 6 that can be raised and lowered, a threshing section 7, a crawler running section 8, and a riding section 9. The machine 3 is equipped with a bagging section 12 for packing the grains into bags 11, and a waste straw binding section 14 for bundling the waste straw group 13 from the threshing section 7 at the rear of the threshing section 7. A mechanism 2 is installed that intermittently releases bundles of bundled waste straw 13 from the machine 3 along the row direction during harvesting work, along the track of the machine 3.
When the straw moves to the lateral side of the waste straw group 13 that has been released into the field, the sensor 1 is activated to detect the presence of the waste straw by coming into contact with it and to operate the release mechanism 2. It is supported by extending outward from the side of the machine 3. The waste straw group discharging mechanism 2 includes a waste straw group receiver 2A that can be freely switched between a waste straw group receiving posture and a waste straw group releasing posture by swinging around a horizontal axis, and a waste straw group receiver 2A that can be freely switched between a waste straw group receiving posture and a waste straw group releasing posture. A spring 2B that swings and urges the receiver 2A to the receiving position while allowing the swing to the releasing position due to the weight of the straw group 13, and the receiver 2A.
The receiver 2A is located on the swing path of the member 2C connected to the
A state in which the swinging of the receiver 2A from the receiving position to the releasing position is prevented but a return to the receiving position of the receiver 2A by the urging force is allowed, and a state in which the receiver 2A is evacuated outside the swinging path and the swinging of the receiver 2A is prevented. It is constructed by providing a ratchet pawl 2D which can be freely switched between the permissible states and a solenoid 2E which switches the ratchet pawl 2D between the two states mentioned above.

The sensor 1 allows the machine 3 to support a support rod 1A that protrudes laterally outward so as to be rotatable around the lateral axis, and has an abutment that can come into contact with the discharge straw group 13 on the support rod 1A. The member 1B is attached to the support rod so that its position can be changed in the longitudinal direction and the member 1B can be rotated and fixed; and a spring 1C that biases the support rod 1A to an operating posture in which the contact member 1B can be brought into contact with the support rod 1A.
1C, and a snitch 1D that closes when the support rod 1A rotates beyond a certain level as the contact member 1B contacts the discharge straw 13, and operates the solenoid 2E of the discharge mechanism 2.
It is configured by providing.

The binding section 14 and the straw discharge mechanism 2 are arranged behind the rear end of the crawler type running section 8, and the sensor 1 is connected to the rear end of the crawler type running section 8 and the straw discharge mechanism 2. It is arranged between the mechanism 2 and the mechanism 2.

1. In this embodiment, when the sensor 1 comes into contact with the discharging straw group 13 and swings during the backward movement of the machine, a device 4 is provided which issues an alarm to stop the machine.

This device 4 is composed of a switch 4A that is turned on when the support rod 1A swings, and a buzzer 4B that is turned on when the switch 4A is turned on. Therefore, according to the above configuration, as shown in FIG. 5, when the machine 3 is located close to the group of waste straw Jl3 released backward as the aircraft moves backward, the crawler type running section 8 moves the waste straw to the rear. Before stepping on the straw group 13, the sensor 1 comes into contact with the discharge straw group 13 during the previous operation, which is located on the side of the discharge straw group 13, and an acoustic alarm is issued.

Furthermore, as described in Japanese Patent Application No. 52-72396, the mechanism for discharging grain storage bags into the field can be freely switched between a state in which the bags are prevented from being discharged and a state in which they are allowed to be discharged. A sensor 1 similar to the sensor 1 that operates a solenoid attached to a locking member that is swingably provided in a state where it is always biased toward the locking side via a spring to activate the straw discharge mechanism 2. Even in the reaping and harvesting machines that work with
It can be carried out in the same manner as in the embodiment described above, and the sensor 1 may act on both the mechanism for discharging the waste straw and the mechanism for discharging the grain storage bag. The bag discharging mechanism, the waste straw discharging mechanism, or both may be configured to be activated based on the detection of a bag.

Note that the engine stop device or the traveling clutch may be linked to the sensor 1, and the aircraft may be configured to automatically stop in conjunction with the contact operation of the sensor 1 when the aircraft is moving backward.
