Description

Technical Field

[0001] This invention relates to the field of agricultural equipment, and in particular to an integrated chrysanthemum harvesting machine. Background Technology

[0002] Chrysanthemums (especially Hangzhou white chrysanthemums) are widely cultivated in many regions of my country due to their medicinal, edible, and ornamental value. However, chrysanthemum harvesting needs to be completed within a short period to ensure the quality and medicinal efficacy of the flowers. Manual harvesting is inefficient and costly in this process. While traditional hand-harvesting ensures the integrity of the flowers, its efficiency is insufficient for large-scale cultivation, and it suffers from high harvesting costs and harvesting pressure caused by the concentrated flowering period. Furthermore, manual harvesting is susceptible to weather conditions, causing delays and affecting the quality of the chrysanthemums.

[0003] While existing mechanized harvesting equipment can improve harvesting efficiency, it does not adequately protect the integrity of the flowers, easily causing damage. This is especially true when harvesting varieties like Hangzhou white chrysanthemum, which have high requirements for appearance. Mechanized harvesting often leads to problems such as flower breakage or complicated secondary separation of stems, affecting subsequent processing and product value. Therefore, the market urgently needs a harvesting device that can efficiently and accurately separate flowers from stems while minimizing flower damage.

[0004] To address this need, this invention proposes a chrysanthemum harvesting device with a sloping comb-like structure, which can efficiently separate chrysanthemums and reduce damage, thus meeting the harvesting requirements of large-scale planting. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the background art and to propose an integrated chrysanthemum picking and harvesting machine.

[0006] To achieve the above objectives, the present invention provides a chrysanthemum harvesting machine, comprising: a main support frame, a separating and gathering component, a cutting component, a clamping and conveying component, a disc-shaped comb-tooth separation component, and a collecting component; the separating and gathering component is located at the front end of the main support frame, the cutting component is located on the right separating device, the clamping and conveying component is located after the separating device and fixed on the main support frame, its drive motor is located at the lower part of the main support frame, the main drive wheel is connected to the drive sprocket in the disc-shaped comb-tooth separation component through a universal coupling, and the collecting component is located on the main support frame.

[0007] In the above scheme, the separating and gathering component further includes a left separator and a right separator. The left separator is a straight trapezoid, and the right separator is welded from a rectangle and a triangle with an included angle of 45°. The left separator separates a large bunch of flowers from the branches into bouquets that can be processed by the equipment, and the right separator gathers the loosely separated bouquets, preparing for the subsequent process.

[0008] In the above scheme, the cutting assembly further includes a circular saw and a motor. The motor is mounted on the right divider. The motor drives the circular saw to rotate. After the chrysanthemum branches are gathered by the divider, the circular saw cuts them off from the root.

[0009] In the above scheme, the clamping and conveying assembly further includes two sets of main drive wheels, auxiliary drive wheels, and belts symmetrically arranged on the left and right. To ensure that the two belts can be tightly pressed together to form sufficient clamping force on the chrysanthemum branches, three elastic push rods are used on each side to keep the two belts tightly pressed together. The motor that drives the belts to rotate is located at the lower part of the main support.

[0010] In the above scheme, the disc-shaped comb tooth separation assembly further includes a driving sprocket, a driven sprocket, a chain, an aligner, a guide rail, a slide block, a comb tooth connector, a spring plate, and a single comb tooth. The guide rail is mounted on the main support, and the line connecting the centers of the semicircles at both ends of the guide rail and the line connecting the centers of the left main drive wheel and the auxiliary drive wheel in the clamping transmission assembly are located in the same vertical plane. The angle between the guide rail and the horizontal plane is 10°. The slide assembly is mounted on a guide rail and connected to a chain. A comb connector is installed on the slide assembly, and each connector has three individual comb teeth. A spring plate is installed between every two individual comb teeth to separate them. When the guide rail is curved at the front end, the comb teeth are separated. As the comb teeth rotate synchronously with the clamping and conveying mechanism, the front end of the comb tooth inserts into the stem below the flower and gradually rises with rotation. Where the guide rail straightens, the bottom of the individual comb tooth aligns with the edge of the aligner, making the individual comb tooth perpendicular to the aligner. The ends of the individual comb teeth are closely arranged, reducing the distance between two teeth. This distance allows the branches to be combed off the flower petals. The disc-shaped comb teeth rotate synchronously with the conveyor belt, achieving a rotational transmission consistent with the bouquet conveying speed. The disc-shaped comb teeth have an overall sloping design, lower at the front and higher at the back. During synchronous rotation, the front end of the comb tooth inserts into the stem below the flower and gradually rises with rotation, progressively separating the flower from the stem. The comb connector has three protrusions corresponding to three individual comb teeth. Each comb tooth has a groove at its bottom, with the groove area larger than the protrusion area, allowing the comb tooth to rotate within a defined angle. A universal coupling ensures that the comb teeth rotate synchronously with the belt.

[0011] In the above scheme, the collecting component further includes a negative pressure suction collector. After the chrysanthemum separates from the stem, the separated flowers are above the disc-shaped comb teeth. As the disc-shaped comb teeth rotate, the originally clamped comb teeth open again at the upper end, and the negative pressure suction collector attracts and collects the flowers.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention employs a sloping comb-tooth structure and synchronous transmission design, enabling chrysanthemums to gradually separate from the stems after being clamped, thus achieving a continuous and rapid harvesting process and significantly improving harvesting efficiency, making it particularly suitable for large-scale planting scenarios. The disc-shaped comb design in the equipment ensures that the flowers experience less mechanical pressure during separation, effectively reducing the flower breakage rate and guaranteeing the quality of the harvested chrysanthemums, making it especially suitable for varieties requiring high flower integrity. This equipment integrates functions such as dividing, gathering, cutting, conveying, separating, and collecting, achieving integrated operation, reducing manual intervention and operational difficulty, and significantly lowering labor costs. The figure-eight divider and clamping conveyor components used in this invention can adapt to chrysanthemum plants of different densities and sizes, giving the equipment strong versatility and suitability for various types of chrysanthemum planting environments. The equipment is equipped with a negative pressure suction collection device, which can efficiently collect the separated flowers, avoiding flower scattering and loss, and ensuring the integrity and cleanliness of the harvesting and collection process.

[0015] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Figure 1-4 The chrysanthemum harvesting machine includes a main support frame 10, a separating and gathering component, a cutting component, a clamping and conveying component, a disc-shaped comb tooth separation component, and a collecting component 9. The separating and gathering component is located at the front end of the main support frame 10, the cutting component is located on the right divider, the clamping and conveying component is located behind the divider and fixed on the main support frame 10, and its drive motor is located at the lower part of the main support frame 10. The main drive wheel 13 is connected to the drive sprocket 7 in the disc-shaped comb tooth separation component through a universal coupling 17, and the collecting component is located on the main support frame 10.

[0017] The separating and gathering assembly includes a left divider 1 and a right divider 16. The left divider 1 is a straight trapezoid, and the right divider 16 is formed by welding a rectangle and a triangle together at a 45° angle. The left divider 1 separates a large bunch of flowers from the branches into bouquets that can be processed by the equipment, while the right divider 16 gathers the loosely separated bouquets together, preparing them for subsequent processes.

[0018] The cutting assembly includes a circular saw 2 and a motor 12. The motor is mounted on the right divider 16. The motor 12 drives the circular saw 2 to rotate. After the chrysanthemum branches are gathered by the divider, the circular saw 2 cuts them off from the root.

[0019] The clamping and conveying assembly includes two sets of main drive wheels 13, auxiliary drive wheels 14, and belts 3 symmetrically arranged on the left and right. To ensure that the two belts are tightly pressed together to form sufficient clamping force on the chrysanthemum branches, three elastic push rods 15 are used on each side to keep the two belts 3 tightly pressed together. The motor that drives the belts 3 to rotate is located at the lower part of the main support 10.

[0020] The disc-shaped comb-tooth separation assembly includes a drive sprocket 7, a driven sprocket 24, a chain 23, an aligner 21, a guide rail 25, a slide block 19, a comb tooth connector 18, a spring plate 20, and a single comb tooth 22. The guide rail 25 is mounted on the main support 10. The line connecting the centers of the semicircles at both ends of the guide rail 25 and the line connecting the centers of the left main drive wheel 13 and the auxiliary drive wheel 14 in the clamping transmission assembly are located in the same vertical plane. The angle between the guide rail 25 and the horizontal plane is 10°. The slide assembly 19 is mounted on the guide rail and connected to the chain 23. A comb connector 18 is mounted on the slide assembly 19, and three single comb teeth 22 are mounted on the comb connector 18. A spring plate 20 is installed between every two single comb teeth 22 to separate them. When the front end of the guide rail 25 is curved, the comb teeth are separated. As the comb teeth rotate synchronously with the clamping and conveying mechanism, the front end of the comb teeth inserts into the stem below the flower and gradually rises with rotation. When the guide rail 25 straightens, the bottom of the single comb tooth 22 aligns with the edge of the aligner 21, making the single comb tooth 22 perpendicular to the aligner 21. The ends of the single comb teeth 22 are closely arranged, reducing the distance between two teeth. This distance allows the branches to be combed down through the flower 6. The disc-shaped comb tooth 4 rotates synchronously with the conveyor belt 3, achieving a rotational transmission consistent with the bouquet conveying speed. The disc-shaped comb tooth 4 has an overall sloping design, lower at the front and higher at the back. During synchronous rotation, the front end of the comb teeth inserts into the stem below the flower and gradually rises with rotation, progressively separating the flower from the stem. The comb tooth connector 18 has three protrusions corresponding to three individual comb teeth 22. Each individual comb tooth 22 has a groove at its bottom, the area of ​​which is larger than the area of ​​the protrusion, allowing the comb tooth to rotate within a defined angle. The universal coupling 17 ensures that the comb teeth rotate synchronously with the belt.

[0021] The collection assembly includes a negative pressure suction collector 9. After the chrysanthemum separates from the stem, the separated flowers are above the disc-shaped comb teeth 4. As the disc-shaped comb teeth 4 rotates, the comb teeth that were originally clamped open again at the upper end, and the negative pressure suction collector 9 attracts and collects the flowers.
