The first driving shaft 32 and the second driving shaft 34 transmit power through a gear set 33, and the power of the first driving shaft 32 is provided by an engine. The cross-shaped shaft fixing frame 26 is provided with a shaft sleeve, the cross-shaped shaft 28 is fixed on the girder 25 through the pair of cross-shaped shaft fixing frames 26, so that the cross-shaped shaft 28 can only rotate around the shaft sleeve on the cross-shaped shaft fixing frame 26, the gap between the upper part of the cross-shaped shaft 28 and the girder 25 is small, the rotating angle of the cross-shaped shaft 28 is also small, the first conveyor belt 30 and the second conveyor belt 31 are prevented from loosening from the first conveyor belt limiting wheel 29, and the first conveyor belt limiting wheel 29 is fixed at the bottom of the cross-shaped shaft 28. A first elastic adjusting structure 27 is installed above the two cross shafts 28, the first elastic adjusting structure may be a compression spring, the first elastic adjusting structure 27 functions to make the upper portions of the two cross shafts 28 away from each other by an elastic force, a stopper is fixed below the cross shaft fixing frame 26, and the thickness of the stopper is equal to the gap between the upper portion of the cross shaft 28 and the girder 25, so that the two cross shafts 28 are kept parallel by the action of the first elastic adjusting structure 27. The first conveyor belt 30 and the second conveyor belt 31 are respectively clamped by the first elastic adjusting structure 27 through the first conveyor belt limiting wheel 29, and the stems of the garlic are clamped to prevent the garlic from falling off. The stopper functions to limit the lower portions of the cross shafts 28 from approaching each other, so that the lower portions of the cross shafts 28 can only rotate around the cross shaft fixing frame 26 in a direction away from the girder 25, when a certain acting force causes one first belt limiting wheel 29 to deviate from the original position, the first elastic adjustment structure 27 is compressed, the acting force is transmitted to the corresponding cross shaft 28, the corresponding cross shaft 28 cannot rotate because the lower portion of the corresponding cross shaft 28 is limited by the stopper, and the first belt limiting wheel 29 deviating from the original position returns to the original position after the acting force is released. So that the first and second conveyor belts 30 and 31 are conveyed backward along their predetermined positions.

Alternatively, the holding and conveying means 4 may be connected, either directly or indirectly, to the seedling-guiding means 2, which is typically planted in a row, and the seedling-guiding means 2 is used to separate the stem of the root crop, such as garlic shoots, and guide the stem into the holding and conveying means 4.

The purpose is to make the upper surface of the garlic have enough contact area with the outer surface of the conveyor belt, so that the garlic is fixed more firmly and cannot be hurt. The positioning device in the prior art can also be provided with two conveyor belts which are horizontally arranged without included angles, so that the garlic can not be well positioned and aligned, and the garlic is easily damaged due to the small contact area between the positioning device and the garlic.

Optionally, the positioning device 8 of this embodiment further includes a third driven rotating shaft 35 and a fourth driven rotating shaft 39, the third driven rotating shaft 35 and the fourth driven rotating shaft 39 are provided with threads and fixed on the fixed pipe 40 through nuts, respectively, the second belt limiting wheel 42 is fixed on the fixed pipe 40 through the limiting wheel fixing shaft 41, and the third driving shaft 45 and the fourth driving shaft 47 transmit power through the universal shaft 46. The power of the third motive shaft 45 is provided by the engine. The relative position between the conveyor belt on the clamping and conveying device 4 and the conveyor belt on the positioning device 8 has special requirements (see fig. 6), so that the distance between the conveyor belt on the clamping and conveying device 4 and the bottom of the conveyor belt on the positioning device 8 is larger and larger, and the garlic bulbs are limited by the third conveyor belt 43 and the fourth conveyor belt 44 and cannot rise, so that the garlic bulbs are stably conveyed backwards all the time below the third conveyor belt 43 and the fourth conveyor belt 44 in the process of backwards conveying, and are conveyed backwards along with the conveyor belts, namely the garlic bulbs can be aligned and conveyed backwards in the gap between the third conveyor belt 43 and the fourth conveyor belt 44, and the function of the positioning device 8 is completed conveniently and quickly.

It should be noted that the third conveyor belt 43 and the fourth conveyor belt 44 do not mean that the positioning device of the root crop combine harvester of the present invention only includes two conveyor belts, and there may be multiple conveyor belts, that is, it can be understood that at least two conveyor belts are divided into the third conveyor belt group and the fourth conveyor belt group, and a certain included angle is formed between the third conveyor belt group and the fourth conveyor belt group.

The included angle between the two conveyor belts in the positioning device 8 and the relative position between the two conveyor belts in the positioning device and the two conveyor belts in the clamping and conveying device 4 in the embodiment can make the garlic bulbs align and transport backwards accurately, and the garlic bulbs can not fall off midway. The bottoms of the two conveyors on the positioning device 8 are at a certain distance. The conveyor belt on the positioning device 8 penetrates through the middle of the conveyor belt on the clamping and conveying device 4, so that the vertical distance between the bottom of the conveyor belt on the positioning device 8 and the vertical distance between the conveyor belt on the clamping and conveying device 4 and the third driven conveyor belt wheel and the vertical distance between the conveyor belt on the clamping and conveying device 4 and the fourth driven conveyor belt wheel are basically equal to zero, the beneficial effects are that the conveyor belt on the positioning device 8 and the conveyor belt on the clamping and conveying device 4 form seamless connection, and garlic easily enters a channel between the two conveyor belts on the positioning device 8.
