Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a machine vision intelligent precision seeding machine. Background Art

[0002] A seeder is an agricultural machine used for planting crops. It is usually used to sow seeds quickly and effectively in farmland and gardens to improve planting efficiency and crop yields. The main function of a seeder is to evenly distribute seeds on the soil surface or at a certain depth under the soil to ensure that the crop planting density is moderate and the arrangement is neat.

[0003] Traditional sowing technology mostly relies on manual or simple mechanical devices to place seeds. This method has obvious limitations. First, manual sowing is labor-intensive and inefficient, and the uniformity and accuracy of sowing are difficult to guarantee. Secondly, although the traditional seedling seeders on the market have improved the sowing efficiency to a certain extent, they are unable to achieve accurate seed placement due to the lack of intelligent control mechanisms and still rely on manual picking. Over-sown seeds need to be manually removed, and under-sown seeds need to be manually replenished, resulting in poor sowing effects. With the rapid development of modern agriculture, the demand for intelligent and automated agricultural machinery and equipment is becoming increasingly urgent. Traditional sowing methods can no longer meet the efficient and precise needs of modern agricultural production. Therefore, a highly intelligent and automated seeder is developed.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1-Figure 3 As shown, a machine vision intelligent precision seeding machine comprises:

[0024] Mounting frame 1;

[0025] A servo motor 2, wherein the servo motor 2 is mounted on the top of the mounting frame 1;

[0026] A driving wheel 3, the driving wheel 3 is fixedly connected to the outside of the output end of the servo motor 2;

[0027] Drum 4, drum 4 is rotatably connected to the outside of driving wheel 3, a disturbance mechanism 5 is arranged on the outside of drum 4, a guide tube 6 is arranged below drum 4, a detection switch 7 is arranged on one side of guide tube 6, a storage box 8 is fixedly connected to the outside of mounting frame 1, a plurality of plug trays 9 are arranged at the bottom end of mounting frame 1, a conveying motor 12 is arranged at the bottom end of plug tray 9, a monitoring camera 11 is fixedly installed on the outer wall of mounting frame 1, a conveying belt 10 is arranged outside conveying motor 12, a negative pressure support shaft tube 13 is sleeved on the outside of drum 4, a guide bracket 14 is arranged below negative pressure support shaft tube 13, a driving roller 15 is fixedly connected to the output end of conveying motor 12, a photographing position 16 is arranged inside mounting frame 1, a plurality of sowing positions 17 are arranged below drum 4, the conveying belt 10 is wrapped and sleeved on the outside of driving roller 15, and the conveying belt 10 is rotatably connected with driving roller 15, a plurality of guide tubes 6 are arranged, and guide tube 6 is horizontally arranged below drum 4.

[0028] Specifically, the guide tube 6 can move up and down to perform the material shifting operation on the roller 4. A plurality of monitoring cameras 11 are horizontally arranged, corresponding to monitoring the plurality of guide tubes 6 respectively. A visual analysis and processing module is arranged inside the monitoring camera 11, so that the machine vision system can capture the number and shape of seeds through a high-definition camera, and use image recognition and processing technology to analyze in real time whether the number and appearance of picked seeds are qualified. The following steps and techniques are usually required: Camera acquisition of images: First, a high-definition camera is installed in the seeder to capture images of seeds in real time, and ensure that the resolution of the camera is high enough to obtain clear seed images. Image preprocessing: The collected seed images are preprocessed, including operations such as removing noise and adjusting image contrast and brightness to improve the accuracy of subsequent image processing. ,Image segmentation: Use image processing technology to segment the background of the seed image from the seeds themselves, so as to accurately identify the number and shape of the seeds later. ,Feature extraction: Extract features from the seed image, such as size, shape, color and other information, to help identify each seed. ,Target detection and recognition: Use machine learning algorithms or image processing algorithms to detect and identify each seed in the seed image, and determine whether the number and shape of the seeds meet the set standards. ,Real-time analysis: Real-time image processing and analysis are implemented in the system to quickly determine whether the number and shape of the seeds are qualified, and output the corresponding results or control signals. ,Feedback control: According to the real-time analysis results, the seeder is adjusted accordingly, such as stopping sowing, adjusting the sowing quantity, etc., to ensure the quality of the seeds and the sowing effect.

[0029] As can be seen from the above, when the machine is in use, the servo motor 2 rotates to drive the driving wheel 3 to rotate, and then drives the drum 4 to rotate clockwise, and the seeds in the storage box 8 fit with the outer surface of the drum 4. Since the negative pressure support shaft tube 13 is connected with negative pressure gas, the drum 4 is connected to the cavity inside the negative pressure support shaft tube 13, and the seeds in the storage box 8 are adsorbed by the prefabricated small holes of the drum 4, and rotate clockwise together with the drum 4 to the photo position 16. The monitoring camera 11 takes a photo for identification. If the identification is qualified, it continues to rotate to the sowing position 17 and sends a signal to the disturbance mechanism 5. The disturbance mechanism 5 knocks the seeds down, and the seeds fall into the guide tube 6 and fall into the inside of the hole tray 9 for transportation. When the monitoring camera 11 takes pictures of unqualified seeds, they can be discarded or filled with qualified seeds.
