[0027] Hereinafter, with reference to the accompanying drawings, the preferred embodiments of the present utility model will be described in detail. It should be understood that the preferred embodiments are only for illustrating the present utility model, rather than for limiting the protection scope of the present utility model.

[0028] As Figures 1-6 Shown, a simple fresh tobacco leaf transportation device disclosed by the present utility model includes a support frame 1 arranged front and back. The support frame 1 is of an inverted "U" - shaped structure, and the support columns of the support frame 1 are of a telescopic structure, which is beneficial for contraction when not in use. Roller 2 is provided at the lower end of the support frame 1. Tobacco loading cloth pocket 3 is provided on the left and right sides or the middle side of the upper end of the support frame 1. Specifically, cross bar 9 is provided at the upper end of the support frame 1, and both ends of the cross bar 9 are located outside the outer ends of the support frame 1. Hooks 10 are distributed on the cross bar 9, and the tobacco loading cloth pocket 3 is hung on the hooks 10. A contraction device is provided between the support frames 1. With such a structure, the device can be easily moved during the harvesting process through the roller 2, and the distance between the support frames 1 can be easily contracted through the contraction device, so as to facilitate the movement of the device in a contracted state to another tobacco ridge for continuous harvesting operation.

[0029] Specifically, the contraction device includes a hinge mechanism 4 provided between the two sides of the support frame 1, and the hinge mechanism 4 is composed of a plurality of hinges arranged crosswise and hinged to each other. In order to improve the stability of the structure, a connecting shaft is provided between the corresponding hinge holes of the hinges, and a guide rail 5 is provided on the support frame 1, and a slider 6 is provided in the guide rail 5. The ends of the crosswise hinges are respectively hinged to one end of the guide rail 5 and the slider 6, and a positioning device of the slider 6 is provided on the support frame 1. In this way, when it is necessary to harvest across the tobacco ridge, the tobacco leaves in the tobacco cloth bag 3 are unloaded at the edge of the tobacco field, and then the hinge mechanism 4 is contracted by moving the slider 6, thereby shortening the distance between the two support frames 1, which can facilitate the overall movement of the device across the tobacco ridge between the tobacco plants, and after moving to the tobacco ridge that needs to be picked, it is unfolded for harvesting. It is also possible to adjust the degree of expansion of the hinge mechanism 4 through the slider 6 according to the distance between the tobacco plants, so that the front and rear support frames 1 can pass through the tobacco ridge, and the positioning device can position the slider 6.

[0030] Furthermore, the positioning device includes a pin 7 provided on the slider 6. A connecting chain connected to the pin 7 can be provided on the slider 6, or a pin hole can be provided on the slider 6. Holes 8 cooperating with the pin 7 are distributed on the support frame 1. In this way, the pin 7 and the hole 8 cooperate with each other to achieve positioning.

[0031] Furthermore, a reinforcing rod 11 is movably connected between the lower ends of the support frames 1, so that the stability of the device during use can be improved through the reinforcing rod 11. Specifically, one end of the reinforcing rod 11 is hinged to one of the support frames 1, and a screw hole is provided on the other support frame 1. The other end of the reinforcing rod 11 is movably connected to the screw hole through a screw. In this way, when the device needs to be moved, the connection of the free end of the reinforcing rod 11 is cancelled, which can avoid obstruction between the reinforcing rod 11 and the tobacco plants when the device is moved across the ridges.

[0032] When in use, first place the support rod of the support frame 1 in the furrow. Figure 5 and Figure 6 As shown, then, by pulling apart the spacing between the support frames 1 and unfolding them to a suitable position, they are positioned by the latch 7 on the slider 6, and then the tobacco cloth bag 3 is installed on the hook 10, and then picking can be carried out. After picking and placing, the device is pulled as a whole to move. When it moves to the end of the ridge, the harvested tobacco leaves can be unloaded, and then the latch 7 is unlocked to shrink the spacing between the support frames 1 to the shortest. Then the device as a whole can pass between the tobacco plants across the ridges until the next ridge is harvested and then unfolded.

[0033] The above are only the preferred embodiments of the present utility model, and do not impose any form of confidentiality restrictions on the present utility model. Any simple modifications, equivalent changes, and decorations made to the above embodiments without departing from the content of the technical solution of the present utility model and based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
