Description

Technical Field

[0001] The invention relates to the field of agricultural equipment, in particular to a chrysanthemum harvesting machine. Background Art

[0002] Chrysanthemum (especially chrysanthemum) is widely planted in many regions of my country due to its medicinal, edible and ornamental value. However, the picking of chrysanthemums needs to be completed in a short period of time to ensure the quality and efficacy of the flowers. In this process, manual picking is inefficient and costly. Although traditional manual picking can ensure the integrity of the flowers, its efficiency is difficult to meet the needs of large-scale planting, and there are problems such as high picking costs and picking pressure caused by concentrated flowering periods. In addition, manual picking is easily affected by factors such as weather, causing picking delays and affecting the quality of chrysanthemums.

[0003] Although some existing mechanized picking equipment can improve picking efficiency, it does not adequately protect the integrity of flowers and can easily cause damage to flowers. Especially when picking varieties with high requirements for appearance, such as chrysanthemums, mechanized picking often leads to flower damage or complicated secondary separation of stems, which affects subsequent processing and product value. Therefore, the market urgently needs a picking equipment that can efficiently and accurately separate flowers from stems and reduce flower damage.

[0004] In response to this demand, the present invention proposes a chrysanthemum picking device with a sloped comb tooth structure, which can efficiently separate chrysanthemums and reduce damage, and is suitable for picking needs of large-scale planting. Summary of the invention

[0005] The purpose of the present invention is to solve the problems existing in the background technology and to propose a chrysanthemum picking and harvesting all-in-one machine.

[0006] To achieve the above objectives, the present invention provides a chrysanthemum picking and harvesting machine, comprising: a main body support, a straw dividing and gathering component, a cutting component, a clamping and conveying component, a disc-type comb tooth separation component, and a collecting component; the straw dividing and gathering component is arranged at the front end of the main body support, the cutting component is arranged on the right straw divider, the clamping and conveying component is arranged behind the straw divider and fixed on the main body support, the driving motor is arranged at the lower part of the main body support, the main drive wheel is connected to the active sprocket in the disc-type comb tooth separation component through a universal coupling, and the collecting component is arranged on the main body support.

[0007] In the above scheme, further, the straw dividing and gathering component includes a left straw divider and a right straw divider, the left straw divider is a straight trapezoid, and the right straw divider is welded by a rectangle and a triangular plate, with an angle of 45°; the left straw divider separates a large bunch of flowers from the branches into a bouquet that can be processed by this equipment, and the right straw divider gathers the loosely separated bouquets; in preparation for the subsequent process.

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

[0009] In the above scheme, further, the clamping and conveying assembly includes two sets of left-right symmetrical main transmission wheels, auxiliary transmission wheels and belts. In order to make the two belts close together to form sufficient clamping force for the chrysanthemum branches, three elastic push rods are used on each side to make the two belts close together. The motor driving the belt to rotate is arranged at the lower part of the main frame.

[0010] In the above scheme, further, the disc-type comb tooth separation assembly includes a driving sprocket, a driven sprocket, a chain, an aligner, a guide rail, a slide assembly, a comb tooth connector, a spring sheet and a single comb tooth. The guide rail is arranged on the main frame, and the connecting line of the centers of the semicircles at both ends of the guide rail and the connecting line of 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, and the angle of the guide rail relative to the horizontal plane is 10°. The slide assembly is installed on the guide rail, the slide assembly is connected to the chain, the comb tooth connector is installed on the slide assembly, and three single comb teeth are installed on the comb tooth connector. A spring sheet is installed between every two single comb teeth to separate the single comb teeth from each other. When the front end of the guide rail is a curve, the comb teeth are separated from each other. As the comb teeth and the clamping transmission mechanism rotate synchronously, the front end of the comb teeth is inserted into the stem below the flower and gradually rises with the rotation. At the point where the guide rail changes from curved to straight, the bottom of the single comb teeth is aligned with the edge of the aligner, so that the single comb teeth are perpendicular to the aligner, and the ends of the single comb teeth are closely arranged to reduce the spacing between the two teeth. This spacing allows the branches to be combed down through the perianth. The disc-shaped comb teeth rotate synchronously with the conveyor belt to achieve a rotation transmission consistent with the speed of the bouquet transmission. The disc-shaped comb teeth are designed as a slope, with the front low and the back high. During the synchronous rotation process, the front end of the comb teeth is inserted into the stem below the flower and gradually rises with the rotation, gradually separating the flower from the stem. There are three protrusions on the comb connector, corresponding to three single comb teeth. There is a groove at the bottom of the single comb tooth. The area of ​​the groove is larger than the protrusion area, so that the comb teeth can rotate within a limited angle. The universal coupling ensures that the comb teeth rotate synchronously with the belt.

[0011] In the above scheme, further, the collection assembly includes a negative pressure suction collector. When the chrysanthemums are separated from the stems, the separated flowers are above the disc-shaped comb teeth. As the disc-shaped comb teeth rotate, the originally clamped comb teeth are spread out again at the upper end, and the negative pressure suction device sucks and collects the flowers.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention adopts a sloped comb tooth structure and a synchronous transmission design, so that the chrysanthemums can be gradually separated from the stems after being clamped, thereby realizing a continuous and rapid picking process, significantly improving the picking efficiency, and being particularly suitable for large-scale planting scenarios. The design of the disc-shaped comb teeth in the equipment enables the flowers to be subjected to less mechanical pressure when being separated, effectively reducing the breakage rate of the flowers, ensuring the quality of the picked chrysanthemums, and is particularly suitable for varieties with high requirements for flower integrity. The equipment integrates functions such as dividing and gathering, cutting, conveying, separating, and collecting, realizing integrated operation, reducing manual intervention and operating difficulty, and greatly reducing labor costs. The eight-character divider and clamping and conveying assembly adopted in the present invention can adapt to chrysanthemum plants of different densities and specifications, making the equipment highly versatile and suitable 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, avoid the loss of flower scattering, and ensure the integrity and cleanliness during the picking and collection process.

[0017] The straw dividing and gathering assembly includes a left straw divider 1 and a right straw divider 16. The left straw divider 1 is a straight trapezoid, and the right straw divider 16 is welded from a rectangle and a triangular plate, with an angle of 45°. The left straw divider 1 separates a large bunch of flowers from the branches into a bouquet that can be processed by the device, and the right straw divider 16 gathers the loosely separated bouquets. This is to prepare for the following process.

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

[0019] The clamping and conveying assembly includes two sets of main transmission wheels 13, auxiliary transmission wheels 14 and belts 3 that are symmetrical on both sides. In order to make the two belts close together to form sufficient clamping force for the chrysanthemum branches, three elastic push rods 15 are used on each side to make the two belts 3 close together. The motor that drives the belts 3 to rotate is arranged at the lower part of the main frame 10.
