A guide plate supporting the reaped stem culm by leaning against it in an inclined position, and a conveyor belt with a locking conveyor protrusion rotated around the axis along the inclination direction of the guide plate. a conveying device for conveying the harvested stem culms supported by leaning against a board to the binding device, and a conveying belt with a locking conveying protrusion around an axis parallel to the rotational axis of the conveying belt in this conveying device. An auxiliary conveyance device that carries out the bundled stem culms laterally and outwardly by rotating the auxiliary conveyance device has a wheel around the starting end of the conveyor belt that is coaxial with a wheel around the conveyor belt at the end of the conveyor. The present invention relates to an agricultural binder located at

[Conventional technology]

In the above-mentioned agricultural binder, conventionally, as shown in Japanese Utility Model Publication No. 50-30261, the auxiliary conveyance device is provided to be swingable around the rotational axis of the winding ring on the starting end side, and the auxiliary conveyance device is Some devices are configured so that the distal end side swings upward as the device swings backward from the sideways protruding position.

[Problem to be solved by the invention]

The above-mentioned conventional structure configures an inclined cam surface between the rotating body that supports the winding wheel on the terminal side and the receiving seat,
From the state in which the auxiliary transport device is set in the operating position where it is connected to the transport device and protrudes outward, when the auxiliary transport device is not in use, the auxiliary transport device is swung to the rear and retracted to reduce the lateral external dimensions of the aircraft. When making the machine smaller and more compact in the width direction to make it easier to drive on the road or store in a barn, etc., it is possible to eliminate the risk of the auxiliary transport device swinging upward and interfering with the propulsion wheels when stored. , so that it can be stored in the most appropriate position.

However, in the conventional structure described above, since it is configured with an inclined cam surface, simply by slightly swinging the auxiliary conveyance device backward from the working position, the winding wheel on the terminal end side will move relative to the winding wheel on the starting end side. As a result, the conveyor belt becomes slack and deforms.
As a result, for example, when reaping near the edge of a ridge where the auxiliary conveyance device comes into contact with the ridge, if the auxiliary conveyance device is tilted slightly backwards while reaping, the locking conveyance protrusion stops and the planting stems are planted. This can cause problems such as getting caught on the culm and tearing it off.

The present invention aims to eliminate the above-mentioned disadvantages through rational structural improvements.

[Means to solve the problem]

The characteristic configuration of the present invention is that a reaping device is provided in the front part of the propulsion wheel, a binding device is provided on one side of the reaping device, and the reaped stem culm is arranged backwardly between the reaping device and the propulsion wheel. The reaped stem culm, which is supported by leaning against the guide plate, is rotated by rotating a conveyor belt with a locking conveyor protrusion around the axis along the inclination direction of the guide plate. A conveying device for conveying the binding device is provided, and by rotating a conveying belt with a locking conveying protrusion around an axis parallel to the rotating axis of the conveying belt in this conveying device, the tied stem culm is moved laterally outward. In an agricultural binder, an auxiliary conveyance device is provided in such a manner that the winding wheel on the starting end side of the conveyor belt is located concentrically with the winding wheel on the terminal end side of the conveyor belt in the conveying device. , the auxiliary conveyance device is provided to be swingable around the rotational axis of the starting-end side wrapping wheel, and in the rotation operation around the rotational axis, the auxiliary conveyance device is configured to rotate with the starting-end side wrapping wheel. The frame is configured so that the center distance is constant with the wrapping ring on the end side, and the end side part of the frame that supports the wrapping ring on the ending side is connected to the starting end part of the frame that supports the wrapping ring on the starting end side. for,
The conveyor belt is configured to be able to bend around the axis of the horizontal axis at a mid-winding position, and the conveyor belt is loosened as the conveyor belt bends and oscillates, and the transmission state is interrupted. .

[Effect]

While the machine is running, the stem culm that is being harvested is stably supported and guided by the guide plate that is tilted backwards, and the culm is perpendicular to the stem culm by the locking conveyance protrusion that rotates around the axis along the guide plate. The rotating axis of the winding wheel on the starting end side for storing the auxiliary transport device is tilted backwards, so that the auxiliary transport device does not swing backwards. As a result, it will interfere with the propulsion wheels, but at this time, by bending the end portion of the frame upward around the horizontal axis, the empty space above the propulsion wheels can be effectively used to move the auxiliary conveyance device upwards. Due to the swinging, the end part of the frame that supports the winding ring on the end side bends at a position midway through the winding of the conveyor belt, loosening the conveyor belt and cutting off the power transmission. The auxiliary conveyance device will not be driven unexpectedly in this state, and there is little risk that the belt will wind around and come off the wheel body when the transmission is cut off. Furthermore, since the above-mentioned backward rocking motion and upward rocking motion can be performed independently, the tension of the conveyor belt does not change even if the auxiliary conveyance device is slightly rocked backwards, so the transmission state can be maintained. It turns out.

〔Effect of the invention〕

Therefore, during normal reaping work, it is possible to smoothly and reliably transport the reaped stem culms laterally using a rational transport method, but when storing the machine or splitting it in the middle, it is difficult to move the auxiliary transport device within the width of the machine. In addition to being able to be stored compactly, the simple structure cuts off power transmission and prevents unexpected drive. Furthermore, when reaping in narrow areas such as along the edge of a ridge, the auxiliary conveyance device can be tilted slightly backwards to avoid contact with the ridge.
The unloading operation of the auxiliary conveyance device could be maintained, and the process of unloading the stems and culms could be carried out smoothly.

Reference numeral 16 denotes a set bolt for fixing the auxiliary conveyance device 12 in a position in which the auxiliary conveyance device 12 is protruded laterally to the outside and the bundled stem culm is carried out laterally to the outside; 17 is a set bolt for swinging the auxiliary conveyor device 12 upward; , frame 1
When the auxiliary conveyor belt 12A is slackened by reducing the 2D, the auxiliary conveyor belt 12A is attached to the pulley 12.
This is an external stopper that prevents it from coming off from B and 12C.

According to the agricultural binder configured in this way,
During normal work, by protruding the auxiliary conveyance device 12 laterally outward, the bundled stem culm can be reliably released to a distant location on the lateral outer side of the machine. When not working, such as storing in a barn, the auxiliary transport device 12 is swung upwards and then swung backwards so that its terminal end is located above the propulsion wheels 1. The auxiliary conveyance device 12 is housed within the width of the machine body to make the body compact in the width direction, and the auxiliary conveyance belt 12A becomes slack and the auxiliary conveyance device 12 becomes inoperable.
