Detailed implementation manners

[0031] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0032] As Figures 1 to 6 shown, a bionic chrysanthemum picking device includes a mobile trolley 10, a harvesting mechanism 20, a collection mechanism 30 and a picking mechanism 40, wherein:

[0033] The harvesting mechanism 20 is arranged in front of the mobile trolley 10 and includes a first rotating shaft 202, a screw blade 203 and a first servo motor 205. The screw blade 203 on the first rotating shaft 202 is driven by the first servo motor 205 to rotate and cut the stalks on the chrysanthemum plants.

[0034] The picking mechanism 40 is arranged above the harvesting mechanism 20 and includes a second rotating shaft 405, comb teeth 406, a third rotating shaft 407, a comb cutter 408, a second servo motor 410 and a third servo motor 416. The shapes of the comb teeth 406 and the comb cutter 408 are both designed based on bionics. The comb teeth 406 on the second rotating shaft 405 are driven by the second servo motor 410 to rotate and pick up the flowers connected to the stalks, and then the comb cutter 408 on the third rotating shaft 407 is driven by the third servo motor 416 to rotate and cut off the flowers connected to the stalks.

[0035] The collection mechanism 30 is arranged behind the picking mechanism 40 and includes a collection box 303 and a centrifugal fan 305. A negative pressure environment is formed in the collection box 303 by the centrifugal fan 305 to suck in the cut flowers.

[0036] In this embodiment, the mobile trolley 10 includes a mounting pipe 101 which is horizontally arranged and oriented left and right. Both ends of the mounting pipe 101 are symmetrically connected with L-shaped mounting brackets 102, and a mounting plate 103 is connected in parallel to the lower part of the mounting brackets 102. A pair of mounting shafts 104 are rotatably connected to the front and back of the mounting plate 103, and mounting wheels 105 are coaxially connected to the ends of the mounting shafts 104. A handrail pipe 106 is arranged in parallel behind the mounting pipe 101, and the handrail pipe 106 is connected to the upper ends of the left and right mounting brackets 102 through a pair of L-shaped mounting strips 107. By holding the handrail pipe 106 and pushing forward, the mobile trolley 10 can be easily driven to move forward.

[0037] In this embodiment, a connecting strip 201 is vertically and downwardly connected to the front end of the mounting bracket 102, and a first rotating shaft 202 is rotatably connected between the left and right connecting strips 201. The auger blade 203 is coaxially fixed to the first rotating shaft 202, and a plurality of harvesting teeth 2031 are distributed at intervals on the edge of the auger blade 203. A first fixed pipe 204 is fixed to the front end of the mounting plate 103. The first servo motor 205 is installed on the first fixed pipe 204 through a fixed seat 206, and a first sprocket 207 is key-connected to its output end. A second sprocket 208 is key-connected to the end of the first rotating shaft 202, and a first chain 209 is installed between the first sprocket 207 and the second sprocket 208. The first servo motor 205 drives the rotation of the auger blade 203 on the first rotating shaft 202 through chain drive, and uses the harvesting teeth 2031 on the auger blade 203 to hook out and cut off the rhizomes of the chrysanthemum plants from the soil. Its spiral structure design twists the stems of the chrysanthemum plants into it during rotation, pulls up the chrysanthemum stems through the pulling force, and then makes them move to the rear of the harvesting mechanism 20 through the spiral structure, realizing the harvesting of the chrysanthemum stems.

[0038] In this embodiment, a support plate 302 is horizontally and forwardly connected to the upper end of the mounting bracket 102. The collection box 303 is installed above the support plate 302. A sealing cover 304 is hingedly connected to the left side of the collection box 303, and a centrifugal fan 305 is installed on the right side of the collection box 303. A collection pipe 306 is vertically installed on the front side of the collection box 303. The centrifugal fan 305 forms a negative pressure environment in the collection box 303 and sucks in the cut flowers. After the collection box 303 is full, the flowers can be taken away by opening the sealing cover 304.

[0039] In this embodiment, a fixed pipe 401 is vertically and upwardly connected to the front end of the mounting frame 102. A movable pipe 402 is slidably connected to the outside of the fixed pipe 401, and a bolt 403 is detachably connected between the two. A fixed bar 404 is obliquely fixed to the upper end of the movable pipe 402. The second rotating shaft 405 is rotatably connected to the lower ends of the left and right fixed bars 404. A plurality of rows of comb teeth 406 are circularly arrayed on the second rotating shaft 405. The third rotating shaft 407 is rotatably connected to the upper ends of the left and right fixed bars 404. A plurality of rows of comb knives 408 are circularly arrayed on the third rotating shaft 407. And the comb teeth 406 in each row and the comb knives 408 in each row are staggeredly distributed. A second fixed pipe 409 is fixed to the upper part of the front side of the collection box 303. The second servo motor 410 is mounted on the second fixed pipe 409 through a second fixing seat 411, and a third sprocket 412 is key-connected to its output end. A fourth sprocket 413 is key-connected to the end of the second rotating shaft 405, and a second chain 414 is installed between the third sprocket 412 and the fourth sprocket 413. A third fixed pipe 415 is fixed to the lower part of the front side of the collection box 303. The third servo motor 416 is mounted on the third fixed pipe 415 through a third fixing seat 417, and a fifth sprocket 418 is key-connected to its output end. A sixth sprocket 419 is key-connected to the end of the third rotating shaft 407, and a third chain 420 is installed between the fifth sprocket 418 and the sixth sprocket 419. The second servo motor 410 drives the comb teeth 406 on the second rotating shaft 405 to rotate and pick up the flowers connected to the stems, and then the third servo motor 416 drives the comb knives 408 on the third rotating shaft 407 to rotate and cut off the flowers connected to the stems.

[0040] In this embodiment, a 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 this embodiment, a fan-shaped collection cover 306 is fixed to the front end of the collection pipe 401. The comb teeth 406 on the second rotating shaft 405 and the comb knives 408 on the third rotating shaft 407 are both located inside the collection cover 306. The collection cover 306 helps to transfer the cut flowers to the front port of the collection pipe 306.

[0042] In this embodiment, the rotation directions of the comb teeth 406 and the comb knives 408 are opposite, and there is a relative rotational speed difference between them. Due to the rotational speed difference between the comb teeth 406 and the comb knives 408, the chrysanthemums can be cut off by the comb knives 408 at the end of the stems, which can greatly reduce the residual length of the stems on the flowers and can also keep the chrysanthemum flowers intact to the greatest extent.

[0043] The working principle of this bionic chrysanthemum picking device:

[0044] Before the picking operation, first align the picking device with the chrysanthemum ridge, and then adjust the total length of the fixed pipe 401 and the movable pipe 402 to adjust the height of the picking mechanism 40, and align the picking mechanism 40 with the chrysanthemum plants waiting to be picked. Drive the comb teeth 406 on the rotating shaft two 405 to rotate through the servo motor two 410. The comb teeth 406 move to the lowest point and insert into the chrysanthemum plants in a circular motion, and reach the end of the chrysanthemum stalk in an oblique upward circular route. Use the bionic-designed comb teeth 406 to simulate the human hand to grab the chrysanthemums on the stalk, and then drive the comb knife 408 on the rotating shaft three 407 to rotate through the servo motor three 416. Cut off the flowers connected to the stalk through the rotating comb knife 408. Since the rotating directions of the comb teeth 406 and the comb knife 408 are opposite and there is a certain relative rotational speed difference, the picking work of chrysanthemums can be better completed. Due to the difference in the rotational speeds of the comb teeth 406 and the comb knife 408, the chrysanthemums can be cut off by the comb knife 408 at the end of the stalk, which can greatly reduce the residual length of the stalk on the flowers and can also maximize the integrity of the chrysanthemum flowers. The staggered layout design of the comb teeth 406 and the comb knife 408 can also enable the comb knife 408 to clean the comb teeth 406 and prevent the chrysanthemums from blocking the gaps between the comb teeth 406. After the flowers on the comb teeth 406 are cut by the comb knife 408, the chrysanthemums enter the collection box 307 through the collection pipe 306 by the adsorption of the centrifugal fan 405. In this way, the continuous picking of chrysanthemums is realized. The operating speeds of the picking comb teeth 406 and the comb knife 408 can be adjusted to adapt to the growth conditions of different chrysanthemums.

[0045] In summary, the present invention solves mechanical technical problems by understanding the structural and functional principles of organisms and imitating the special structures of organisms to develop new machinery. For example, the design of the bionic chrysanthemum picking machine simulates the process of manually peeling chrysanthemums to improve some of the disadvantages brought by traditional picking mechanisms and ensure the integrity of chrysanthemum flowers.

[0046] Therefore, the above-disclosed embodiments are illustrative in all respects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
