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]

Regarding the above-mentioned agricultural binder, the following techniques have been conventionally known.

The conveying and releasing device is composed of a main conveying device that conveys the stem culms that are supported by leaning against the guide plate to the binding device side, and an auxiliary conveying device that conveys the bundled stem culms to the lateral outside of the machine body, and , the pulley on the transport end side of the auxiliary transport device is supported by a frame supported by an inclined cradle, and as the frame supporting the end end pulley rotates around the axis of the start end pulley, both A system in which the looseness of the belt stretched between the pulleys is used to cut off the power transmission of the auxiliary conveyance device and to move the terminal pulley toward the inside of the machine (for example, Utility Model Publication No. 50-30261) Public bulletin).

The conveying and discharging device is composed of a main conveying device that conveys the stem culms leaning against and supported by the guide plate to the binding device side, and an auxiliary conveying device that conveys the bundled stem culms to the lateral outside of the machine body, An auxiliary conveyance device is provided to be swingable around a horizontal axis along the longitudinal direction of the machine, and is configured to cut off power transmission to the auxiliary conveyance device as the conveyance end side of the auxiliary conveyance device is swung downward. (For example, in the 1970s

[The problem that the idea aims to solve]

However, among the above conventional structures, in the one described in (1), transmission is interrupted due to loosening or tension of the belt. There was a risk that it would be difficult to carry out the process reliably.

In addition, in the above-mentioned device, the rotational drive shaft of the main conveyance device and the drive driven shaft of the auxiliary conveyance device are transmitted via the transmission pin, so that transmission can be interrupted or disconnected regardless of whether the belt is loosened, etc. However, since the auxiliary conveyance device is structured to swing and retract around the longitudinal axis of the machine body, agricultural binders with a structure in which a wide propulsion wheel is present on the lower side are not suitable for the auxiliary conveyance device inside the machine body. Storing the machine on both sides is restricted due to interference with the propulsion wheels, and the width of the machine is not sufficiently compact when stored. In so-called mid-splitting work, in which the machine is run and reaps in the presence of grain, the auxiliary conveyance device located on the side of the machine comes into contact with the planted stem culm, causing harmful effects such as tearing of grains. There was a problem that would arise.

This invention enables reliable on-off transmission of power to the auxiliary transport device regardless of belt elongation, and allows the storage position of the auxiliary transport device to be moved sufficiently inward to the inside of the machine without being restricted by the position of the wheels. Its purpose is to allow it to be positioned.

(g) A biasing means for elastically biasing the auxiliary conveyance device toward the clutch engagement side is provided on the pedestal.

[Effect]

The effects of taking the above technical measures are as follows.

a The conveyance/discharge device is configured by a combination of a main conveyance device and an auxiliary conveyance device, and the auxiliary conveyance device is mounted so as to be swingable around the axis of the rotational drive shaft of the end-side winding wheel in the main conveyance device. Therefore, the orientation of the auxiliary transport device can be switched between an extended position along the transport direction of the main transport device and a folded position along the outside of the aircraft, crossing the transport direction of the main transport device. I can do it. Therefore,
During normal operations, both the main and auxiliary transport devices are used to ensure that the bundled stem culm is ejected to the side away from the aircraft, and to prevent factors that may impede the straightness of the aircraft, such as the traveling device stepping on the ejected culm. Although it can be removed, when the machine is located near a ridge and the work is performed, the auxiliary transport device is installed so that the auxiliary transport device that extends laterally and outwardly does not come into contact with other objects such as the ridge. Work can be done by switching to the folded state.

b By positioning the rotational axis of the conveying and discharging device in an inclined position tilting backward along the direction of inclination of the guide plate, the stem culm to be harvested can be guided in a state where it is stably supported by the guide plate in the backward tilting position. While
Since the locking and conveying protrusions can be operated in a state perpendicular to the reaped stem culm, locking and conveying can be carried out smoothly and reliably. Because the rotational axis of the conveying and discharging device is tilted in this way, the terminal end side moves downward as the auxiliary conveying device swings backward around its axis. However, by swinging this auxiliary transport device upward around the horizontal axis provided on the pedestal, it can be positioned above the propulsion wheels, avoiding the wheel position and moving the airframe of the aircraft. It can be stored in the space.

c Also, as the auxiliary conveyance device swings upward, the rotating drive shaft of the wrapping wheel on the main conveying device side and the rotating passive shaft of the wrapping wheel on the auxiliary conveying device side are connected. Since transmission to and from the auxiliary conveyance device is interrupted and interrupted by the operation of a clutch provided between the belts, transmission can be interrupted and interrupted without being affected by elongation of the belt or the like.

d Furthermore, a fixing means is provided for positioning the pedestal and the frame of the auxiliary transport device to prevent rotation around the axis with respect to the frame of the main transport device, and the auxiliary transport device is clutched onto the pedestal. Since a biasing means for elastically biasing the side is provided, the frame of the main transport device, the pedestal, and the frame of the auxiliary transport device are fixed while receiving the elastic biasing action of the biasing means. It is fixed in a non-rotating state by means.

[Effect of the invention] 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, At the edge of the ridge, the auxiliary transport device can be switched to a folded position to avoid contact with other objects while working.Furthermore, in the retracted state, it can be stored in an empty space without being affected by the presence of the propulsion wheels, and the This has the effect of making it compact and allowing intermediate cutting work to be carried out without any problems.

In addition, the power to the auxiliary conveyance device can be switched on and off over a long period of time reliably by using the clutch rather than by slackening the belt.

Furthermore, the frame of the main conveyance device, the pedestal, and the frame of the auxiliary conveyance device can be securely and elastically pressed together, making it easy to do so with less rattling.
