Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural seeding, and particularly relates to a system capable of realizing mechanized and efficient production of oriented corn seeds. Background Art

[0002] Oriented sowing of corn seeds is a planting technique that can increase the yield of corn. Oriented sowing of corn seeds means sowing the corn seeds in a specific direction, enabling the leaves of the corn plants to receive sunlight more fully during growth, improving the photosynthesis efficiency, and at the same time being beneficial to ventilation and air permeability, creating good environmental conditions for the growth of corn, thereby increasing the yield and quality of corn. Generally, it is determined according to natural conditions such as local light and wind direction. For example, in the Northern Hemisphere, usually the embryo of the corn seed is oriented in the north-south direction, so that the leaves can better receive sunlight in the east-west direction after unfolding. Using a special oriented seeding machine, the corn seeds are sown into the soil in a predetermined direction through precise mechanical devices, ensuring that the sowing depth is consistent, generally 3 - 5 cm.

[0003] Currently, the commonly used technical means in the prior art include: 1. Manual planting; 2. Using specific equipment for precise sowing of corn seeds. In the first method, because manual planting itself depends on the operator, the work efficiency is low, and it is only suitable for small-scale planting. Moreover, this planting method seriously consumes human physical strength. In the second method, since the corn seeds need to be sown into the land with a specific orientation and depth, very delicate equipment is required, resulting in high costs, which are difficult for ordinary farmers to bear, hindering the popularization of technology. Moreover, when the land covers the corn seeds, it will also generate a thrust on the corn seeds, resulting in a change in the posture of the corn seeds, seriously affecting the orientation, and the increase in yield will also be greatly reduced. Therefore, the popularization and application of the oriented planting technology are severely hindered.

[0004] Therefore, how to ensure the orientation of corn seed sowing without increasing costs and reducing work efficiency is a technical problem that urgently needs to be solved at present. Summary of the Invention

[0005] A main object of the present invention is to provide an oriented corn seed belt preparation system that can ensure the orientation of corn seed sowing without increasing costs and reducing work efficiency.

[0006] To achieve the above invention object, the present invention adopts the following technical solutions:

[0007] As an aspect of the present invention, a system for preparing a directional maize seed belt is provided. The system for preparing a directional maize seed belt is used to form a seed belt, in which maize seeds are evenly and directionally arranged and fixed on a strip. The system for preparing a directional maize seed belt includes an image recognition device, an attitude adjustment device, a maize seed conveying device, a paper tape conveying device, and a control device. The image recognition device is used to identify the attitude information of maize seeds. The attitude adjustment device adjusts the attitude of the maize seeds under the control of the control device according to the information data obtained by the image recognition device, and delivers them to the maize seed conveying device in the correct attitude. The maize seed conveying device evenly and stably conveys the delivered maize seeds to the paper tape conveyed by the paper tape conveying device in sequence. The paper tape conveying device is used to convey the paper tape. The control device is communicatively connected to the image recognition device, the attitude adjustment device, the maize seed conveying device, and the paper tape conveying device to control the coordinated actions of the image recognition device, the attitude adjustment device, the maize seed conveying device, and the paper tape conveying device.

[0008] In an embodiment of the present invention, the image recognition device integrates a machine vision system for morphological curvature detection and embryo surface color feature analysis, and uses an improved YOLOv5s model to identify the orientation of maize seeds, so as to analyze the shape and curvature features of maize seeds and the color features of the embryo surface of maize seeds to identify the orientation of maize seeds.

[0009] In an embodiment of the present invention, the image recognition device obtains an image dataset of maize seeds and uses a labeling tool to label the positions and categories of maize seeds in the images, and increases data diversity through operations such as rotation, scaling, and color transformation to improve the generalization ability of the model, and then uses Python and a deep learning framework for training.

[0010] In an embodiment of the present invention, the system for preparing a directional maize seed belt further includes a gluing device, which evenly sprays an adhesive on the strip to adhesively fix the maize seeds when they enter the strip.

[0011] In an embodiment of the present invention, the seed belt conveying device includes a conveyor belt, a driving wheel set, and a driving mechanism. The conveyor belt is correspondingly arranged below the attitude adjustment device and is wound around and installed on the driving wheel set. The driving mechanism drives the driving wheel set to act under the control of the control device.

[0012] In an embodiment of the present invention, the strip is a paper tape.

[0013] In an embodiment of the present invention, in the seed belt, the tips of the maize seeds face downward and are perpendicular to the paper tape, and the embryo surfaces of the maize seeds are parallel to the long axis of the paper tape and the embryo surface orientations cover the paper tape.

[0014] In an embodiment of the present invention, the paper tape is double-layered, and the corn seeds are clamped therein and pasted on the lower-layer paper tape.

[0015] In an embodiment of the present invention, the corn seeds are pasted on the paper tape through an adhesive.

[0016] In an embodiment of the present invention, the corn seeds are monocotyledonous plants with five cotyledons. When germinating, the cotyledons grow along the axial direction of the seeds one by one. The first cotyledon grows along the tip direction of the embryo, from the tip of the seed to the rear end of the seed, and the tip of the seed faces the wider side. After that, each cotyledon is strictly alternately alternate.

[0017] As can be seen from the above technical solutions, the advantages and positive effects of the system for preparing the oriented corn seed tape of the present invention are as follows:

[0018] In the present invention, when using the system for preparing the oriented corn seed tape to make the seed tape, the corn seeds in the seed tape are evenly and oriented arranged on the paper tape, and oriented sowing is realized, ensuring that the leaf direction is perpendicular to the row direction, achieving the maximum light energy utilization efficiency. Then, through the seed tape sowing device, it is sown into the growth environment of the corn seeds. When the land is covered, the seed tape can relieve the land thrust, and the posture of the corn seeds will not change. Moreover, the production of the seed tape and the sowing of the seed tape are carried out separately, simplifying the production and sowing of the seed tape, with simple cost, and can realize mechanized operation, ensuring work efficiency and reducing human intervention.
