It is fixed to the front end of 11 in parallel with the extension.

The cross belt 2 is a V-belt or a flat belt as shown in the figure. The cross belt 2 is provided below the endless belts 1 and 1 and has a plurality of protruding portions 12... It protrudes with.

The crossed belt 2 is located lower than the endless belts 1, 1 intersecting the driven belt 22, which is located behind the rotation center of the driving belts 71a, 71b. The driven belt wheel 22 is wound around a driving belt wheel 32, and the axle of the driven belt wheel 22 is inclined in the direction of a feed conveyor 3 disposed horizontally and downstream as shown in FIG. It is wound around the vehicle 22 and the driving belt wheel 32 to create a twisted portion 2 ′ whose middle part intersects. As shown in FIG. 1, the crossed belt 2 has a steeper slope than the endless belts 1 and 1 and has root vegetables 100 (specifically) between the endless belts 1 and 1 at the rear end side. It is arranged so as to separate a space Y slightly larger than the diameter of the main body 102 (the portion having the largest diameter), and obliquely intersects one endless belt body 1, 1 in plan view. The center extension line Z in the radial direction of the driving pulleys 71a and 71b, which are the belt pulleys on the upper end side as described above, transfers the root vegetables 100 conveyed by the crossed belt 2 as shown in FIG. Conveyor 3 upstream end (transfer start end)
Are inclined upward so as to increase the space Y between them.

As shown in the figure, the cross-over direction of the cross-over belt body 2 is such that the upper belt portion 2 "intersecting the twisted portion 2 'has a vertical surface at the lower end, and the inclination gradually increases toward the rear end and becomes higher. Is multiplied so as to be horizontal.

The driven pulley 22 on the upper end side of the crossed belt 2 is mounted on an arm 13 projecting from a machine frame (not shown) of the feed conveyor 3 as shown in FIG.
And is supported substantially coaxially with the rotation shaft 33 of the motor.

As shown in FIG. 2, the drive source of the cross belt 2 is a rotary shaft 33 upstream of the feed conveyor 3 which is rotated by a hydraulic motor 23 which is a drive source of the feed conveyor 3.
This is performed by winding a belt body 43 composed of a V-belt or a flat belt as shown indirectly over the axle 32a of the driving belt wheel 32. The cross strap belt 2 may be covered with a cover (not shown) so that the portion other than the upper belt portion 2 "is not exposed.

The root vegetable harvesting apparatus B having such a configuration drives the above-mentioned drive source 41 at the time of harvesting so that the root vegetables 100 in which the front ends (lower ends) of the endless belt bodies 1, 1 are planted. Is rotated so as to be at the same height position with respect to the root portion of the leaf group 101. In that state, the endless belt body 1, 1,
The crossed belt 2 and the feed conveyor 3 are driven at the same speed, and the tractor, which is the self-propelled machine A, runs parallel to the root vegetables 100 planted in rows. Then, as shown in FIG. 1 and FIG. 3, the leaf group 101 of the root vegetables 100 is a nail for guiding.
It reaches the starting end of the holding space X through the space between 11 ′ and 11 ′ and is held in the holding space X between the pair of endless belt bodies 1. At this time, as shown in FIGS. 1 and 2, the root vegetables 100 are vectors of a lifting force by the pair of endless belt bodies 1 and 1 which are conveyed upward and inclined backward, and a traveling force (forward force) by the self-propelled machine A. It is easily pulled out by the upward pulling force generated by the relationship, and is further conveyed upward while being pinched. On the way, the upper belt part 2 ″ of the crossed belt body 2
Of the body 102 near the root 10
2 'is hooked and ascending, the protruding portion 12 for changing its direction changes from a vertical state to a substantially horizontal state, and the main body 102 is moved due to the arrangement relation in which the crossed belt body 2 approaches the endless belt bodies 1 and 1. The rear end (upper end) is set to be substantially horizontal (in a lying state). Then, as shown in FIGS. 1 and 2, when the pair of endless belt bodies 1 and 1 are released from being pinched at the rear end (upper end), the feed conveyor 3 remains in a horizontal state (in a lying state). In this case, all the root vegetables 100 are further transported downstream in the same direction. This series of actions is performed for root vegetables 100 1
This operation is continuously performed for one line. Further, as shown in FIG. 4, the driving belt wheel on the upper end side of the endless belt bodies 1, 1
The center extension line Z in the radial direction of 71a, 71b is
Of the endless belt bodies 1, 1, the lower ends of the axles of the belt wheels 71 a, 71 b and the upstream end of the feed conveyor 3. When the space Y between the starting ends is increased, the root vegetables are placed on the lower ends of the axles of the driving pulleys 71a and 71b when they are laid horizontally and transferred to the feed conveyor 3.
The 100 will no longer be rubbed and damaged.

The feeding conveyor 3 is formed in a corrugated shape as shown in the figure, and the concave portion 53 serves as a portion for placing root vegetables, on which the sorting, grading and the like can be performed. Although the sorting space is not shown in the drawing, it is arranged behind the self-propelled aircraft A.

The endless conveyors 1 and 1 and the crossed conveyor 2 are preferably made of rubber or synthetic resin material which is kind to the root vegetables 100 and has relatively large frictional resistance.

[0021]

According to the present invention, the root vegetables 100 can be continuously pulled out from the ground and transported to a harvesting box, etc. The inefficiency of harvesting caused by the work can be solved. In addition, the extracted root vegetables 100 are placed horizontally (in a lying state)
It is possible to continuously and easily perform sorting and grading by sorting on the contacting sorting conveyor, and it is possible to carry out sampling and sorting (including grading), as well as transport to the harvest box. This significantly reduces the work time and period required for the work, and significantly reduces the labor of the operator. In addition, the apparatus has a simple structure including the endless belt bodies 1 and 1 and the crossed belt body 2, and can be easily attached as an option to a self-propelled machine such as a crawler, which leads to an increase in equipment costs. Not even. At the time of sorting (including grading), the extracted root vegetables are lined up in the same direction, so that operations such as sorting and grading are even easier. Moreover, the center extension line Z in the radial direction of the pair of belt wheels 71a, 71b on the upper end side of the endless belt bodies 1, 1 is connected to the transport start end, which is the upstream end of the feed conveyor 3 for transporting the root crops 100 downstream. Is inclined upward so as to widen the space Y of the endless belt body 1.
The space Y between the lower end of the axle b and the starting end of the conveyance of the feed conveyor 3 is widened, and when transferring to the feed conveyor with the crossed belt 2, the lower end of the axle lower end of the belt wheel 71 b on the upper end side of the endless belt 1. By preventing the root vegetables 100 from coming into contact with each other, damage to the root vegetables can be prevented.
