The present invention is configured as described above.
The following effects are obtained.

As set forth in claim 1, a preparation device for supplying bulb crops collected from a field to a transport device and cutting the foliage and roots of the bulb crops during the transport process of the transport device is arranged on a traveling device. A self-propelled bulb crop preparation machine,
Since the preparation device and the traveling device are configured to be driven by one drive source, the cost can be reduced without providing an extra power source, and the body can be made compact.

According to a second aspect of the present invention, a clutch is provided between the output shaft of the drive source and the input shaft of the transmission of the traveling device, and between the output shaft of the drive source and the input shaft of the preparation device. The operating tools are connected to the clutches, respectively, so that they can be turned on and off independently, so that either the preparation device or the traveling device, or both of them, can be easily switched using the operating devices. Since the operation according to the supply condition of the bulb crops can be performed, a series of adjustment operations of the bulb crops can be favorably performed.

According to a third aspect of the present invention, in the bulb crop preparing machine according to the first or second aspect, a clutch is provided between an output shaft of the driving source and an input shaft of a transmission of a traveling device. Is provided on at least one of the left and right sides with respect to the traveling direction of the preparation device.
It can be easily switched by both the control unit and the preparation device, and when moving slowly while working on the preparation device side during work, either side of the bulb crop preparation machine without operating the control unit each time The operation of starting and stopping can be performed at. In addition, when moving, the usability is improved when used on steep slopes of agricultural roads or corners of fields, or when loading a bulb crop preparation machine onto a truck bed.

According to a fourth aspect of the present invention, there is provided a bulb crop preparing machine for supplying a bulb crop collected from a field to a transport device and cutting the foliage and root of the bulb crop in the transport process of the transport device. A cutting device is provided at the foremost part of the bulb crop supply section of the apparatus as a pre-processing section, and the pre-processing section is configured to perform rough cutting work on the root and foliage of the bulb crop. The bulb crops that are cut to the required minimum length and pass through the preparation device are stably transported by the transport device without lubrication because they do not have long foliage, and the foliage cut in the final preparation is Since it is short, it is difficult to deposit inside the machine body, so that it is not entangled or clogged with the machine, and the precision of preparation is improved.

According to a fifth aspect of the present invention, there is provided a bulb crop preparation machine which supplies a bulb crop collected from a field to a transport device and cuts the foliage and root of the bulb crop in the transport process of the transport device. Since the root cutting device and the cutting device for rough cutting of the foliage are arranged on the front and rear opposite sides with respect to the transport direction of the bulb crop, the long foliage of the bulb crop discharged by the rough cutting operation of the preparation device is scattered. Instead, it falls into a shooter provided below the cutting device and is discharged. Therefore, since the discharged stems and leaves of the bulb crop are not entangled with the rotating member of the transport device and the operation of the transport device is not hindered, the workability can be improved.

According to a sixth aspect of the present invention, there is provided a bulb crop preparing machine for supplying a bulb crop collected from a field to a transporting device and cutting the foliage and root of the bulbous crop in the transporting process of the transporting device. Since the transport belt holds and transports the bulb crops, and the transport belt on one of the left and right sides of the transport device is configured to drive a cutting device for performing a rough cutting operation of the foliage of the bulb crops, the preparation is performed. The cutting device can be driven by a simple driving mechanism even at a position far away from the main power unit of the device.

According to a seventh aspect of the present invention, in the bulb crop preparing machine according to the sixth aspect, a clutch is provided between an input shaft of the preparing device and an output shaft of a driving source, and the clutch is turned on and off by the clutch. Therefore, the operation of the preparation device can be easily switched between operation and stop with the operation tool during the operation. Further, by providing the clutch operating tool of the preparation device on the preparation device side, for example, in a self-propelled bulb crop preparation machine in which the preparation device is mounted on the traveling device, another person operates the control unit while preparing on the preparation device side. The safety is improved without starting the preparation device by mistake from the side.
