[0038] In the embodiment, the upper end of the mounting rack 102 is horizontally forwardly connected with a support plate 302, the collecting box 303 is installed above the support plate 302, the left side of the collecting box 303 is hingedly connected with a sealing cover 304, the right side of the collecting box 303 is installed with a centrifugal fan 305, and the front side of the collecting box 303 is vertically installed with a collecting pipe 306. The cut flowers are sucked into the collecting box 303 by the centrifugal fan 305 to form a negative pressure environment, and the flowers can be taken away by opening the sealing cover 304 after the collecting box 303 is filled.

[0039] In the embodiment, the front end of the mounting frame 102 is vertically connected with a fixed tube 401, the outer side of the fixed tube 401 is slidingly connected with a movable tube 402, and a latch 403 is detachably connected between the fixed tube 401 and the movable tube 402, the upper end of the movable tube 402 is obliquely fixed with a fixed bar 404, the second rotating shaft 405 is rotatably connected to the lower end of the left and right fixed bars 404, the comb teeth 406 are arranged in rows and circularly arrayed on the second rotating shaft 405, the third rotating shaft 407 is rotatably connected to the upper end of the left and right fixed bars 404, the comb blades 408 are arranged in rows and circularly arrayed on the third rotating shaft 407, and each row of the comb teeth 406 and each row of the comb blades 408 are staggered, the front side of the collecting box 303 is fixed with a second fixed tube 409, the second servo motor 410 is installed on the second fixed tube 409 through a second fixed seat 411, and a sprocket 412 is keyed connected to the output end of the second servo motor 410, the end of the second rotating shaft 405 is keyed connected with a sprocket 413, and a chain 414 is installed between the sprocket 412 and the sprocket 413, the front side of the collecting box 303 is fixed with a third fixed tube 415, the third servo motor 416 is installed on the third fixed tube 415 through a third fixed seat 417, and a sprocket 418 is keyed connected to the output end of the third servo motor 416, the end of the third rotating shaft 407 is keyed connected with a sprocket 419, and a chain 420 is installed between the sprocket 418 and the sprocket 419. The comb teeth 406 on the second rotating shaft 405 are driven to rotate by the second servo motor 410, the flowers on the stems are inserted, and then the comb blades 408 on the third rotating shaft 407 are driven to rotate by the third servo motor 416, and the flowers on the stems are cut off.

[0040] In the embodiment, the triangular support frame 301 is connected between the mounting frame 102 and the support plate 302. The support frame 301 can increase the structural connection strength between the mounting frame 102 and the support plate 302.

[0041] In the embodiment, the front end of the collecting tube 306 is fixed with a fan-shaped collecting cover 307, and the comb teeth 406 on the second rotating shaft 405 and the comb blades 408 on the third rotating shaft 407 are located in the collecting cover 307. The collecting cover 307 helps to transfer the cut flowers to the front end of the collecting tube 306.

[0042] In the embodiment, the rotating directions of the comb teeth 406 and the comb blades 408 are opposite, and there is a relative speed difference between them. Due to the speed difference between the comb teeth 406 and the comb blades 408, the chrysanthemum can be cut off by the comb blades 408 at the end of the stem, which can greatly reduce the residual length of the stem on the flower, and also maximize the integrity of the chrysanthemum flower.

[0043] The working principle of the bionic chrysanthemum picking device is as follows:

[0044] Before picking, the picking device is aligned with the chrysanthemum ridge, and the total length of the fixed tube 401 and the movable tube 402 is adjusted to adjust the height of the picking mechanism 40, and the picking mechanism 40 is aligned with the chrysanthemum plant to be picked. The comb teeth 406 on the shaft 2 405 are rotated by the servo motor 2 410, the comb teeth 406 are moved to the lowest position to insert the chrysanthemum plant in a circular motion, and reach the end of the chrysanthemum stem in a circular route to the upper side, and the comb teeth 406 simulate the human hand to grab the chrysanthemum on the stem, and the comb cutter 408 on the shaft 3 407 is rotated by the servo motor 3 416, and the flower connected to the stem is cut off by the rotating comb cutter 408. Because the rotating directions of the comb teeth 406 and the comb cutter 408 are opposite, and there is a certain relative speed difference, the picking of the chrysanthemum can be better completed. Because of the difference in the rotating speed of the comb teeth 406 and the comb cutter 408, the chrysanthemum can be cut off at the end of the stem, which can greatly reduce the residual length of the stem on the flower, and also maximize the integrity of the chrysanthemum. The staggered layout design of the comb teeth 406 and the comb cutter 408 can also make the comb cutter 408 complete the cleaning work of the comb teeth 406, and the comb teeth 406 can be blocked by the chrysanthemum. After the flower on the comb teeth 406 is cut by the comb cutter 408, the chrysanthemum is sucked into the collection tank 307 through the collection pipe 306 by the centrifugal fan 405, and the process is repeated to realize the continuous picking of the chrysanthemum. The rotating speed of the picking comb teeth 406 and the comb cutter 408 can be adjusted to adapt to the growth of different chrysanthemums.

[0045] In summary, the present application solves the technical problems of the mechanical technology by understanding the structure and function principle of the organism and imitating the special structure of the organism to develop new machines. For example, the design of the bionic chrysanthemum picking machine simulates the process of picking chrysanthemums by hand to improve some shortcomings of the traditional picking mechanism and ensure the integrity of the chrysanthemum.

[0046] Therefore, the above disclosed embodiments are only examples and are not the only ones. All changes within the scope of the present application or within the scope equivalent to the present application are included in the present application.
