<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 . 8 is an enlarged perspective view of blade 81 and conveyor 82. FIG.

(blade)
The blade 81 is a member that cuts the root portion 10c of the onion 10 and digs up the bulb portion 10a of the onion. The blade 81 includes a plate-like 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-like members 812 extending toward the conveyor 82 . The plate-shaped blade 811 is positioned in the soil while the foliage processing machine 1 is moving forward, and cuts the roots 10c of the onions 10 planted in four rows at once.

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

(Conveyor)
The conveyor 82 is a member that conveys the bulb portion 10a of the onion 10 transferred from the rod-shaped member 812 backward and discharges it onto the ridge D. As shown in FIG. The conveyor 82 includes a rotating shaft 821 , rear sprockets 822 and 823 , front sprockets 824 and 825 , left and right chains 826 and 827 , and a transport section 828 .

A sprocket 99 is fixed to the right end of the rotating shaft 821 to which driving force from the engine 51 is input. The sprockets 822 and 823 are fixed to both left and right ends of the rotating shaft 821 and rotate as the rotating shaft 821 rotates. Sprockets 824 and 825 are driven side sprockets. Chain 826 is wound around sprockets 822 and 824 and chain 827 is wound around sprockets 823 and 825 . The conveying portion 828 has rod-shaped members that connect 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 conveying portion 828 are rotated by the driving force from the engine 51, and the conveying portion 828 conveys the ball portion 10a of the onion 10 transferred from the rod-shaped member 812 to the rear. eject upwards. At this time, the soil adhering to the spherical portion 10a is removed by the vibration during transportation by the transportation portion 828. As shown in FIG.

(guide)
As shown in FIG. 7, the guides 83 are a pair of left and right plate-like members provided so as to narrow the transport path of the transport section 828 toward the rear. As the material of the guide 83, for example, an elastic material such as rubber can be used. The spherical portion 10a conveyed by the conveying portion 828 is guided by the guide 83 and discharged near the center of the ridge D. As shown in FIG.

(gauge wheel)
The gauge wheels 84 are wheels that hold the digging device 8 at an appropriate height by being grounded, and are arranged in pairs on the left and right sides of the conveyor 82 so as to straddle the ridges D. As shown in FIG. 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 of penetration of the blade 81 into the soil can be adjusted.

(Angle adjustment lever)
The angle adjustment lever 85 is a lever that adjusts the angle of the digging device 8 in the front and rear direction. By turning the angle adjusting lever 85 to the left or right, the forward and rearward angle of the digging device 8 can be made gentle or sharp. The front and rear angles of the digging device 8 are adjusted according to the hardness of the ridges D and the conveying condition of the ball portion 10a. For example, the steeper the angle of the digging device 8, the longer the time that the spherical portion 10a stays on the conveying portion 828, and the more the soil adhering to the spherical portion 10a is removed.

(assist spring)
In the foliage processing machine 1, the digging device 8 is configured to be vertically movable. FIG. 3 shows the digging device 8 in its lowered working position. FIG. 9 shows the digging device 8 in its raised, stowed position.

The assist spring 86 is a tension spring that biases the digging device 8 upward. The assist spring 86 is an auxiliary spring that does not have enough tension to lift the digging device 8 in the working position and reduces the load on the user when manually raising the digging device 8 in the working position. A hydraulic mechanism or an electric mechanism can be used instead of the assist spring 86 .

According to the digging device 8, the root portion 10c of the onion 10 can be cut, and the bulb portion 10a of the onion 10 can be dug up and discharged. Therefore, by using the foliage processing machine 1, the need for a root cutter and a digger is eliminated. As a result, in the harvesting work of the onions 10, the work efficiency can be improved by reducing the number of work machines and the work man-hours.
