The cutter mounting plate connecting flange 42 is connected to the gearbox second shaft gear 49, and the gearbox second shaft gear 49 is meshed with the gear at the lower end of the cutter mounting plate connecting flange 42. The gearbox is installed in the upper housing 53 through two bearings, and the third shaft 51 of the gearbox is installed inside the cutting knife mounting plate connecting flange 42. The cutting knife mounting plate connecting flange 42 is installed with a cutting knife mounting plate 18 by bolts. The upper surface of the lower part of the cutting knife mounting plate 18 is installed with a bionic segmentation knife 19 by bolts. The lower surface of the lower part of the cutting knife mounting plate 18 is respectively installed with a grass brush 24 and a cutting table connecting plate 27 through the bolt holes for installing the bionic cutting knife 19. Since the large gear 49 of the second shaft of the gearbox and the cutting knife mounting plate connecting flange 42 are large gears with small gears, the rotation speed of the cutting knife mounting plate connecting flange 42 is greatly increased, and then the bionic cutting knife 19 meets the requirement of higher cutting line speed of the bionic cutting knife 19.

[0044] The intermediate crop divider 23 includes an intermediate crop divider lower mounting plate 23-4 and an intermediate crop divider mounting plate 23-5, which are used to install the intermediate crop divider. A side crop divider guard plate 23-1 is arranged on the intermediate crop divider mounting plate 23-5, and an intermediate crop divider upper plate 23-2 and an intermediate crop divider crop-moving finger 23-3 are arranged on the side crop divider guard plate 23-1. When working, the intermediate crop divider mounting plate 23-5 is located below the bionic cutter 19 to protect the bionic cutter 19.

[0045] When the cutter operation is needed, the driver drives the hooking machine and can easily hook the cutter on the hooking machine by observing the position identification point set above the suspension frame 4. Then the hooking machine lifts the cutter so that the lower hanging point on the hooking machine is turned into the hanging point below the suspension frame 4 until it reaches the installation position. At this time, the locking motor quick connector 13 is relative to the quick connector on the hooking machine, so that the locking motor quick connector 13 is energized, and then the locking motor 12 is activated through the control button on the hooking machine to rotate the cutter hook locking frame 11 upward to lock the lower hanging point of the cutter, so that the cutter is locked on the hooking machine, and then the driver connects the hydraulic connector on the hooking machine to the hydraulic motor quick connector 15, so that the hydraulic motor 16 is powered.

[0046] The straw rod mounting frame 31 can be moved forward and backward in the mounting position of the suspension frame 4, and the height angle can be adjusted around the rear mounting point. The straw rod 1 installed on the straw rod mounting frame 31 can be rotated around its front suspension point, and then the height, angle and front and rear position of the cutting platform straw rod 1 can be adjusted according to the working environment or the working object.

[0047] The harvesting table is mounted on the hooking implement, and the whole machine starts to work. The hydraulic motor 16 starts to work through the control button in the cab of the hooking implement. The power is transmitted from the hydraulic motor to the two gearboxes through the transfer shaft 35 and two transfer gears, namely the first transfer gear 33 and the second transfer gear 54. Through the gearbox speed change, the reed disc 5 obtains a lower rotation speed and linear speed, and the cutter mounting disc 18 obtains a higher rotation speed and linear speed to meet the requirements of the operation. Since the reed disc 5 has a low rotation speed and a large torque when working, and is responsible for the feeding of materials and bears a large resistance, if the harvesting table is blocked during feeding, the torque on the reed disc 5 increases, resulting in the breakage of the safety pin 41 connecting the reed disc transfer flange 39 and the reed disc mounting flange 36, cutting off the power of the reed disc 5 and preventing damage to other transmission components.

[0048] When the whole machine is in operation, as the attachment tool moves forward, the cutting platform starts to harvest. When the ground is undulating or uneven, the height of the attachment point of the attachment tool is adjusted to control the cutting height and the inclination of the cutting platform to meet the harvesting operation. When the driver operates improperly and makes the cutting platform too low, the cutting platform side divider 21, the cutting platform side guard frame 7, and the cutting platform lower guard plate 25 first contact the ground to prevent other parts of the cutting platform from contacting the ground and causing accidents or damage. The cutting platform side divider 21 is The mounting pin 20 of the harvesting platform side crop divider is installed on the side guard beam 28, and the harvesting platform side crop divider 21 can rotate around the mounting pin 20 of the harvesting platform side crop divider. When the harvesting platform side crop divider 21 touches the ground, the front guard plate 21-4 of the side crop divider is tilted upward, so that the harvesting platform side crop divider 21 will not be inserted into the ground, but will rotate around the mounting pin 20 of the harvesting platform side crop divider. Since the side crop divider limit plate 21-3 limits the lowest rotation position of the harvesting platform side crop divider, the harvesting platform side crop divider 21 will not rotate too low.

[0049] When the whole machine is harvesting, the side dividers 21, the dividers 22 and the straw support rod 1 of the cutting platform first contact the harvested crops, and the straw support rod 1 pushes the crops forward to facilitate the transportation of the side dividers 21, the dividers 22 and the straw disc 5 and the chopping work of the bionic cutter 19. The two side dividers 21 of the cutting platform gather the crops on the inner edge of the cutting width of the cutting platform through the side divider guard plate 21-1 and the side divider straw fingers 21-2 as the whole machine moves forward, until they reach the working range of the bionic cutter 19 and the straw disc 5. The crops in the middle of the cutting width are also divided to both sides by the middle divider 23 of the cutting platform The crops in the working range of the crop divider 22 are gathered inward by the crop dividing teeth, which is convenient for the bionic cutter 19 to cut the crops and the crop disc 5 to transport the cut crops. The cut materials are transported upward through the middle crop divider upper plate 23-2. Due to the limitation of the crop support rod 1, as the cut materials are transported backward on the cutting platform, the cut materials are laid down horizontally, which is convenient for the subsequent material shredding work. When the materials continue to be input backward, the grass clearing knife 29 separates the crop disc 5 from the crops. At this time, the cutting platform completes the crop harvesting work.

[0050] The grass brush 24 and the cutting table connecting plate 27 installed at intervals on the lower surface of the lower part of the cutter mounting plate 18 rotate with the rotation of the cutter mounting plate 18. Due to the tooth shape arranged under the grass brush 24, weeds or harvested crops hanging on the lower part of the cutting table or the grain divider 22 and other parts can be taken away. At the same time, since the lower surface of the cutting table connecting plate 27 is flat, the grass brush 24 and the cutting table connecting plate 27 have an alternating impact on the weeds or harvested crops hanging on the lower part of the cutting table or the grain divider 22 and other parts, so that the weeds or harvested crops hanging on the lower part of the cutting table or the grain divider 22 and other parts are easy to fall off, keeping the cutting table clean and preventing the cutting table from being blocked and unnecessary power waste.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
