According to such a drive transmission mechanism 9, the power from the engine 51 is transmitted to the sprocket 99 via the pulley 91, the belt 93, the chain 97, 100, etc. provided on the transmission shaft 12, and is dug from the sprocket 99. It is transmitted to the picking device 8. Further, by operating the conveyor drive lever 66, the tension pulley 94 can be moved to control the drive and stop of the conveyor 82. Further, since the drive transmission mechanism 9 is arranged at the right end of the foliage processing machine 1 and is located outside the transport path of the digging device 8, it does not interfere with the transport of the onion 10 in the digging device 8.

<Digging device>
The digging device 8 is arranged behind the foliage discharging device 31 and includes a blade 81, a conveyor 82, a guide 83, a gauge wheel 84, an angle adjusting lever 85, and an assist spring 86. FIG. 8 is an enlarged perspective view of the blade 81 and the conveyor 82.

(blade)
The blade 81 is a member that cuts the root portion 10c of the onion 10 and digs up the ball portion 10a of the onion. The blade 81 includes a plate-shaped blade 811 having a length in the width direction of the ridge D and extending in the left-right direction, and a plurality of rod-shaped members 812 extending toward the conveyor 82. The plate-shaped blade 811 is located in the soil during the advancement of the foliage processing machine 1 to cut the root portion 10c of the onion 10 planted in the four rows at a time.

The rod-shaped members 812 extend from the rear portion of the plate-shaped blade 811 to the rear-upward direction, and are arranged side by side in the left-right direction at intervals shorter than the diameter of the spherical portion 10a. The rod-shaped member 812 digs up the spherical portion 10a in the soil and guides it to the conveyor 82 as the foliage processing machine 1 advances.

(Conveyor)
The conveyor 82 is a member that conveys the ball portion 10a of the onion 10 delivered from the rod-shaped member 812 to the rear and discharges it onto the ridge D. The conveyor 82 includes a rotating shaft 821, rear sprockets 822 and 823, front sprockets 824 and 825, left and right chains 828 and 827, and a transport section 828.

A sprocket 99 is fixedly installed at the right end of the rotating shaft 821, and a driving force from the engine 51 is input. The sprockets 822 and 823 are fixed to the left and right ends of the rotating shaft 821 and rotate by the rotation of the rotating shaft 821. The sprockets 824 and 825 are sprockets on the driven side. The chain 826 is wound around the sprockets 822 and 824, and the chain 827 is wound around the sprockets 823 and 825. The transport portion 828 has rod-shaped members connecting the left and right chains 826 and 827, and the distance between the rod-shaped members is shorter than the diameter of the spherical portion 10a.

As a result, the chains 826 and 827 and the transport unit 828 are rotated by the driving force from the engine 51, and the transport unit 828 transports the ball portion 10a of the onion 10 delivered from the rod-shaped member 812 to the rear, and the rear ridge D Discharge upwards. At this time, the soil adhering to the ball portion 10a is removed by the vibration when being transported by the transport unit 828.

(guide)
As shown in FIG. 7, the guide 83 is a pair of left and right plate-shaped members provided so as to narrow the transport path of the transport unit 828 toward the rear. As the material of the guide 83, an elastic material such as rubber can be used. The ball portion 10a transported by the transport portion 828 is guided by the guide 83 so as to be brought close to the center of the ridge D and discharged.

(Gauge wheel)
The gauge wheels 84 are wheels that hold the digging device 8 at an appropriate height by touching the ground, and are arranged in pairs on the left and right sides of the conveyor 82 so as to straddle the ridges D. The gauge wheel 84 is configured to be able to move up and down, and by adjusting the height of the gauge wheel 84, the depth at which the blade 81 enters the soil can be adjusted.

(Angle adjustment lever)
The angle adjusting lever 85 is a lever that adjusts the front-rear angle of the digging device 8. By turning the angle adjusting lever 85 to the left or right, the front-rear angle of the digging device 8 can be made gentle or steep. The front-rear angle of the digging device 8 is adjusted according to the hardness of the ridge D and the transport condition of the ball portion 10a. For example, the steeper the angle of the digging device 8, the longer the time for the ball portion 10a to stay on the transport portion 828, and the soil adhering to the ball portion 10a is removed cleanly.

(Assist spring)
In the foliage processing machine 1, the digging device 8 is configured to be able to move up and down. FIG. 3 shows a state in which the digging device 8 is lowered and in the working position. FIG. 9 shows a state in which the digging device 8 is raised and is in the storage position.

The assist spring 86 is a tension spring that urges the digging device 8 in the ascending direction. The assist spring 86 is an auxiliary spring that does not have enough tension to lift the digging device 8 at the working position and reduces the load on the user when manually raising the digging device 8 at the working position. It is also possible to use a hydraulic mechanism or an electric mechanism instead of the assist spring 86.

According to the above-mentioned digging device 8, the root portion 10c of the onion 10 can be cut, and the ball portion 10a of the onion 10 can be dug up and discharged. Therefore, by using the above-mentioned foliage processing machine 1, a root cutting machine and a digging machine become unnecessary. As a result, in the harvesting work of the onion 10, the work efficiency can be improved by reducing the number of working machines and the work man-hours.
