Description

Technical Field

[0001] The invention relates to the field of agricultural equipment, and in particular to a pepper picking roller and a picking method. Background Art

[0002] In the pepper planting industry, the picking process consumes a lot of manpower and time costs. Traditional picking methods mostly rely on manual labor, which is inefficient and difficult to meet the needs of large-scale planting. Some existing mechanical picking devices have poor adaptability to the morphology of pepper fruits, and peppers of different shapes and sizes are difficult to be picked effectively. Moreover, during the separation process, it is easy to cause mechanical damage to the pepper fruits, reducing the quality and economic benefits of the peppers. In addition, traditional picking devices are often unable to perform adaptive adjustments according to the maturity of the peppers and other conditions, resulting in poor picking effects. Therefore, there is an urgent need for a pepper picking device and method that is efficient, low-damage and can adapt to different situations. Summary of the invention

[0003] The purpose of the present invention is to provide a pepper picking roller and a picking method to solve the problems that traditional picking devices have poor adaptability to fruit morphology and are prone to mechanical damage during the separation process, thereby improving the efficiency and quality of pepper picking and reducing labor costs.

[0004] A pepper picking roller and a picking method of the present invention are characterized in that the device comprises a rotating roller 1, an elastic paddle array 2, a transmission mechanism 3, an image recognition module 4 and a cutting assembly 5;

[0005] The surface of the rotating roller 1 is provided with a unique curved silicone pick. The silicone material has good flexibility and elasticity, which can reduce the hard squeezing of the pepper fruit and avoid damage when the pepper fruit is moved. The curved design fits the common shape of the pepper and can more effectively grab the pepper.

[0006] The elastic paddle array 2 is composed of a plurality of elastic paddles, which are arranged on the surface of the rotating roller in a certain pattern. During the picking process, the peppers are separated from the plants by flexible paddles.

[0007] The transmission mechanism 3 includes a variable frequency motor and a planetary gear set. The variable frequency motor can flexibly adjust the speed of the rotating roller according to factors such as the growth, maturity and planting density of the peppers; the planetary gear set ensures stable transmission of power, so that the rotating roller runs smoothly.

[0008] The image recognition module 4 integrates a depth camera and a near-infrared spectrum detection unit. The depth camera can obtain the three-dimensional spatial information of pepper plants and fruits, and identify the position and growth posture of peppers; the near-infrared spectrum detection unit is used to detect the maturity of peppers, providing a basis for subsequent adjustment of picking parameters.

[0009] When the elastic paddle moves the pepper fruit, the cutting assembly 5 synchronously drives the cutting assembly to cut off the fruit stalk. The cutting assembly uses a sharp and durable knife to ensure that the fruit stalk can be cut off quickly and accurately, while avoiding additional damage to the pepper fruit and the plant.

[0010] The beneficial effects of the present invention are:

[0011] 1. The present invention greatly improves the adaptability to pepper fruits of different shapes through the unique design of elastic paddles and arc-shaped silicone paddles, and effectively solves the problem of poor adaptability of traditional picking devices to fruit shapes.

[0012] 2. By combining flexible pushing and precise cutting, the pepper picking damage rate is reduced to less than 2%, which significantly improves the quality and economic benefits of peppers.

[0013] 3. With the help of the coordinated work of the image recognition module and the variable frequency motor, adaptive adjustment of picking parameters is achieved, the harvesting success rate is increased to more than 95%, and the operating efficiency is increased by 4-6 times compared with manual work. It is very suitable for continuous harvesting operations in high-density planting scenarios, greatly improving the efficiency of pepper picking and reducing labor costs.
