[0002] Hemp is an agricultural product that mostly grows between 1.8 meters and 3.0 meters in length.

[0040] When the equipment is running, the driving part of the equipment moves, driving the entire frame 1 to move toward the crop direction. The upper section cutting transmission frame 2 is located at the front and contacts the hemp crop first. The upper section cutting transmission frame 2 cuts the hemp crop as follows: the reel 4 cooperates with the upper section cutting transmission frame 2, and the reel divider 5 guides the upper section of the hemp crop to the entrance of the hemp clamping conveyor belt 6 for clamping, and then the cutting knife device 7 cuts off the upper section of the hemp clamped by the hemp clamping conveyor belt 6, and the hemp clamping conveyor belt 6 is transported to the hemp rear transmission device 8. On the running track of the hemp clamping conveyor belt 6 and the hemp rear transmission device 8 for transporting the upper section of the hemp, an upper section tip cutting device 9 for cutting the upper section of the hemp is provided, which can cut off the tip of the upper section of the hemp. Finally, the upper section of the hemp is regularly transported to the field ground by the hemp rear transmission device 8;

[0041] The lower section cutting transmission frame 3 then contacts the hemp crops cut by the upper section cutting transmission frame 2. Since the upper section cutting transmission frame 2 clamps the upper section of the hemp crop, it also indirectly supports and helps the lower section cutting transmission frame 3 to clamp, cut and transport the lower section of the hemp. The structural principle of the lower section cutting transmission frame 3 is the same as that of the upper section cutting transmission frame 2. The cut lower section of the hemp on the lower cutting transmission frame is also transported to the hemp post-transmission device 8 by the hemp clamping conveyor belt 6. Finally, the lower section of the hemp is regularly transported to the field ground by the hemp post-transmission device 8.

[0042] Through the above technical principles, a hemp segmented harvester realizes the mechanized operation of hemp harvesting, from overall harvesting to segmented cutting, and prepares for the subsequent mechanized baling of hemp, reducing the labor cost of hemp from cutting to peeling, and avoiding the dust problem in the enclosed space caused by manual segmentation and cutting operations in the workshop.

[0043] As for the above-mentioned equipment components, ordinary technicians in this field should know that the frame 1 can be set to a corresponding state according to the actual arrangement, the reel 4, the reel divider 5, and the cutting knife device 7 are common agricultural machinery parts in the prior art, the upper tip cutting device 9, the hemp clamping conveyor belt 6 and the hemp rear conveyor 8 realize their functions in the existing agricultural machinery technology, and have many common structural components. The terminology of the upper tip cutting device 9, the hemp clamping conveyor belt 6 and the hemp rear conveyor 8 is limited only to express the function of the component structure. Therefore, it can be understood that it is only a simple replacement of the component structure. When the matching relationship of the above-mentioned components is stable, it cannot be considered to exceed the limited protection scope of the above-mentioned structure.

[0044] In the present embodiment, the hemp clamping transmission belt 6 is provided with more than one transmission channel, and the transmission channel is connected with the opening between two adjacent hemp dividers 5; clamping transmission belts are provided on both sides of the transmission channel, and the clamping transmission belts are installed with a plurality of pulleys, and a power driving pulley 625 is provided among the plurality of pulleys.

At the same time, the pulley has a power driving pulley 625 to drive the clamping transmission belt to make a circular motion in the corresponding direction.

[0046] In this embodiment, at least one of the two clamping transmission belts on both sides of each transmission channel is a power drive pulley 625;

[0047] When only one of the two clamping transmission belts on both sides of a transmission channel has a pulley which is a power-driven pulley 625, the power-driven pulley 625 drives the clamping transmission belt to move, and simultaneously drives the hemp crops in the transmission channel and the other clamping transmission belt to move through friction.
