[0041] 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 first contacts the hemp crop. 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. Then the cutting knife device 7 cuts off the upper section of 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.

[0042] 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 lower section of the hemp cut on the lower end 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.

[0043] Through the above technical principles, a hemp segmentation harvester realizes the mechanized operation of hemp harvesting, from overall harvesting to segmented cutting, and prepares the preliminary work 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.

[0044] As for the above-mentioned equipment components, ordinary technicians in this field should know that the frame 1 can be set to the corresponding state according to the actual layout. The reel 4, the straw 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 noun terms of the upper tip cutting device 9, the hemp clamping conveyor belt 6 and the hemp rear conveyor 8 are only used to express the function of the component structure. Therefore, it can be understood that it is just 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.

[0045] In this embodiment, the hemp clamping transmission belt 6 is provided with more than one transmission channel, and the transmission channel is connected to the opening between the adjacent two straw dividers 5; clamping transmission belts are provided on both sides of the transmission channel, and the clamping transmission belts are installed with several pulleys, and a power drive pulley 625 is provided among the several pulleys.

[0046] The structure of the hemp clamping transmission belt 6 is a pair of adjacent clamping transmission belts, which jointly clamp the hemp crops in the transmission channel and transport them to the target position. Each clamping transmission belt is correspondingly installed on the upper cutting transmission frame 2 and the lower cutting transmission frame 3 through a rotatably installed pulley. At the same time, the pulley has a power drive pulley 625 to drive the clamping transmission belt to make a circular motion in the corresponding direction.

[0047] 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;

[0048] 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. The number and power configuration of the power-driven pulleys 625 can be handled according to specific usage.

[0049] In this embodiment, the power drive pulley 625 is installed on the inner surface of the clamping transmission belt, and the outer surface of the clamping transmission belt is installed with a limiting pulley 626 to increase the contact area between the power drive pulley 625 and the inner surface of the clamping transmission belt.

[0061] The structural principle of the above-mentioned hemp clamping conveyor belt 6 is that when it works, the hemp crops first enter the first transmission channel 613, the second transmission channel 614, the third transmission channel 615, the fourth transmission channel 616, the fifth transmission channel 617 and the sixth transmission channel 618 through the six openings between the dividers 5. The twelve clamping conveyor belts on both sides of the above-mentioned six transmission channels are circulated by the power output of the power drive pulley 625, and the hemp crops in the above-mentioned six transmission channels are respectively transported to the seventh transmission channel 619, the eighth transmission channel 620 and the ninth transmission channel 621, and then the eighth transmission channel 621 is connected to the hemp crop belt 613.

[0062] The first guide member 627, the second guide member 628, the third guide member 629, the fourth guide member 630 and the fifth guide member 631 are all V-shaped plates, which can guide the hemp crops when they enter the intersection of the three transmission channels, preventing the hemp materials from circulating to other positions along the original clamping transmission belt and smoothly entering the predetermined transmission position.

[0063] Through the design of the hemp clamping conveyor belt 6, the hemp clamping conveyor belt 6 has a better spatial layout and higher power utilization efficiency.

[0064] In this embodiment, a material guide 633 is provided above the transmission channel.

Finally, the pressing conveyor belt 902 transmits the upper hemp material with the tip cut off to the hemp post-transmission device 8.
