A spherical crop preparation machine in which an endless transport belt is wrapped around a pulley, and when the front extension transport portion is erected around a left-right axis to prevent excessive slack of the endless transport belt. Is provided with a belt retainer which is engaged in the lengthwise direction of the conveyor belt.

[0005] In the present invention, the front extension transport section enables the spherical crop on the ridge to be supplied at a relatively low position, and the transport belt transports the spherical crop supplied to the front extension transport section to the body of the machine. Will do. The front extension conveyance unit is swingably operated in an upright state around a left-right axis, so that the front-rear length of the entire body is reduced. The belt retainer engages with the transport belt when the front extension transport section is in the upright swinging displacement, thereby acting to prevent the belt from excessively relaxing and restricting the belt from coming off the pulley.

In the spherical crop preparation machine according to the second aspect of the present invention, a front extension transport section is provided at the front end of the body body so as to be swingable about a left-right axis, and a pulley provided on the body body section includes A spherical crop preparation machine in which an endless transport belt is wrapped around a pulley provided in an extension transport section, wherein a belt retainer is provided at a position above the transport belt in a forward extension transport section, and the belt retainer extends forward. When the transport unit is erected around the left-right axis, it is configured to press the upper side of a portion near the left-right axis of the transport belt.

In the present invention, the belt presser regulates the upward movement of the conveyor belt to prevent the conveyor belt from coming off the pulley. When the front extension conveyance unit is erected and oscillated, the belt presser presses the portion of the conveyance belt in the vicinity of the left-right direction axis, thereby reducing the inclination displacement of the conveyance belt with respect to each pulley and reducing the length of the conveyance belt between the two pulleys. The length variation is kept small, and the conveyor belt is effectively prevented from coming off the pulley. At this time, the degree of tension of the transport belt is appropriately reduced, and unnecessary tension of the transport belt is avoided. Further, the front extension conveyance section and the conveyance belt have the same function as the first aspect of the invention.

According to a third aspect of the present invention, there is provided a spherical crop preparation machine, wherein a front extension conveying section is provided at the front end of the main body so as to be swingable about a left-right axis, and a pulley provided on the main body is provided with a pulley.

The spherical portion t3 is supplied to the front portion of the first transporting device 8 while the spherical portion t3 is positioned above the spherical portion supporting and transporting device 6 in the inverted posture in which the upper portion 2 is in the upright position. At this time, if the front portion of the front extension conveyance section is lowered and inclined rearward and upward, the onion on the ridge is efficiently supplied to the first conveyance device 8 with little labor. The onion supplied in this way is held by the spherical portion supporting and transporting device 6 at the boundary between the spherical portion t3 and the foliage portion t1, and the foliage portion t1 is gripped by the gripping and transporting device 25 to form the two transport mechanisms 6.25.
Is reliably transported rearward without the whole becoming unstable. In the initial stage of the transport, the foliage t1 is largely expanded downward, but as the transport progresses, the left and right side portions thereof are pressed by the left and right support means 19, 19, which are inclined backward. Since the foliage is guided in such a manner that the foliage extends from the portion close to the spherical portion t3 toward the tip, the pressing position shifts from a high position to a lower position and is gradually reduced.

While the transport while supporting the spherical portion t3 is continued by the spherical portion supporting and transporting device 6, the nipping transport device 25

Further, while the onion is being conveyed, the earth and sand adhering to the onion may fall off and enter the intersection of the horizontal sliding surface a and the vertical sliding surface b. In such a case, the onion moves backward. The conveyor belts 14 and 14 act to convey the earth and sand backward, and the earth and sand move through the hole c during the movement of the earth and sand by this action.
No. 01 drops directly below and is removed to the back side of the vertical sliding contact surface b, and does not accumulate at the intersection.
