Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a reaping device at the front part of the propulsion wheel, a binding device at one side of the reaping device, and connects the reaping device and the propulsion device. A guide plate that leans and supports the reaping device in a backward tilted position, and a transport and release system that transports the reaped stem culms to the side of the machine by rotating a transport body with a locking transport protrusion. The present invention relates to an agricultural binder comprising an apparatus.

[Conventional technology]

In the above agricultural binder, conventionally, as disclosed in Japanese Utility Model Publication No. 50-10341, for example, the conveying and discharging device is used as a main conveying device that leans against the guide plate and conveys the supported stem culms to the binding device side. ,
The auxiliary transport device is configured to transport the bundled stem culms to the lateral and outer side of the machine body, and the auxiliary transport device is provided to be swingable around a horizontal axis along the longitudinal direction of the machine body. Some devices are designed to cut off power transmission to the auxiliary conveyance device as the device swings.

[The problem that the idea aims to solve]

However, in the conventional structure described above, since the auxiliary transport device is swung and stored around the longitudinal axis of the aircraft, there are wide propulsion wheels that protrude laterally on the lower side of the auxiliary transport device. When stored in the lower position, the storage range is limited due to interference with the propulsion wheels.
The width of the aircraft was not sufficiently compact when stored, and there was room for improvement. In addition, if the auxiliary conveyance device is swung even slightly from the predetermined sideways protruding position to the retracted position, the power transmission is cut off. In so-called mid-splitting work, in which the machine is run and reaps in the presence of This results in harmful effects such as tearing of the grains.

The present invention aims to solve the above-mentioned problems through rational structural improvement.

[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 a binding device is provided between the reaping device and the propulsion device so that the reaping device cannot be tilted backwards. The reaped stem culm is conveyed to the side of the machine by rotating a guide plate that leans against and supports the guide plate in an inclined position, and a conveyor body with a locking conveyance protrusion around the axis along the inclination direction of the guide plate. The present invention provides an agricultural binder equipped with a conveying and discharging device having the configurations described in [A] to [C] below.

[B] The conveyance and discharge device is a combination of a main conveyance device that conveys the stem culms that are supported by leaning against the guide plate to the binding device side, and an auxiliary conveyance device that conveys the bundled stem culms to the lateral outside of the machine body. It is made up of.

[B] The auxiliary conveyance device is arranged such that the starting end side wrapping wheel is positioned concentrically with the rotational axis of the ending side wrapping wheel with respect to the conveying body in the main conveying device, and The auxiliary conveyance body is provided with a locking conveyance protrusion that is configured to be rotatable around an axis parallel to the conveyance body, and the terminal end of this auxiliary conveyance body is separately connected to the starting end side winding wheel body. It is configured to be able to swing backwards around the axis, and swing upwardly around the horizontal axis so that the terminal end is at the upper side.

[C] At the transmission point between the main conveyance device and the auxiliary conveyance device, a clutch is provided that cuts off the power transmission to the drive shaft of the auxiliary conveyance device in conjunction with the backward or upward swinging of the auxiliary conveyance device beyond a certain level. It is provided.

[Effect]

As the machine advances, the stem culm to be harvested is stably supported and guided by the guide plate that is tilted backwards, and at the same time, the locking conveyance protrusion is placed in a state perpendicular to the guide plate, that is, the reaped stem culm. acts, so
Locked conveyance can be carried out smoothly and reliably, and because the oscillating axis of the auxiliary conveyance device is located in an inclined position tilting backwards along the direction of inclination of the guide plate, the auxiliary conveyance device cannot be swung backwards. Although the terminal end drops downward as it moves, by swinging this auxiliary transport device upward, it can be positioned above the propulsion wheels, allowing it to be effectively and compactly stored in the empty space of the aircraft. Become. As the auxiliary conveyance device swings upward as described above, the power transmission to the drive shaft is cut off, so when the auxiliary conveyance device swings backward as described above, the transmission state is maintained and the predetermined storage position is maintained. If set to , the transmission will definitely be cut off.

[Effect of idea]

Therefore, during normal reaping work, by protruding the auxiliary conveyance device laterally and outwardly, it is possible to connect to the main conveyance device and smoothly release the bundled stem culms, and in the retracted state, it is possible to smoothly release the bundled stem culms from above the propulsion wheels. It can be reliably stored in the empty space on the side, making the aircraft more compact in the width direction. In addition, when the auxiliary conveyance device is slightly swung backwards, the transmission state can be maintained, so for example, when reaping at the edge of a ridge,
When the auxiliary conveyance device comes into contact with a ridge in its protruding position, there is an advantage that the auxiliary conveyance device can be tilted slightly backwards to maintain the driving state even when traveling for reaping, and the reaped stem culm can be carried out smoothly. .
