Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting technology, and in particular relates to a corn seed breeding height measuring device. Background Technology

[0002] In agriculture, maize, as one of the world's most important food crops, plays a crucial role in breeding for increasing yield, improving quality, and enhancing stress resistance. Seed height, the vertical distance from the base of the seed (radicle end) to the tip (plumule end), is a key morphological indicator in maize breeding. This indicator is not only closely related to the growth and development characteristics of maize but also directly affects its final yield and quality. Therefore, rapidly and accurately measuring maize seed height is an indispensable part of maize breeding research.

[0003] However, traditional methods for measuring maize seed height primarily rely on manual operation, such as measuring each seed individually using calipers or rulers. This method is not only inefficient and unsuitable for large-scale breeding operations, but also susceptible to human error, leading to significant measurement results. Furthermore, manual measurement cannot achieve batch processing, further limiting its application in efficient breeding processes.

[0004] With the continuous advancement of technology, automation and intelligent technologies are gradually penetrating the agricultural field, bringing new opportunities to maize breeding. Although some automated measuring devices have been developed for measuring various morphological parameters of crops, there are still many shortcomings in measuring maize seed height. For example, some devices are complex in structure and cumbersome to operate, making them difficult to deploy and use quickly in breeding fields; others lack sufficient measurement accuracy to meet the needs of high-precision breeding research.

[0005] Therefore, developing a maize seed height measurement device that is simple in structure, easy to operate, highly accurate, and capable of batch measurement is of great significance for improving maize breeding efficiency and promoting the development of maize breeding research. This invention is based on this background and aims to provide an efficient and accurate solution for measuring maize seed height to meet the practical needs of modern agricultural breeding work.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1:

[0029] To classify and breed maize seeds in batches and verify whether related characteristics are related to maize seed height, we designed an efficient maize seed height measurement device. This device can quickly and accurately measure maize seed height in batches, providing strong support for maize breeding work.

[0030] Please see Figure 1-5 As shown, this utility model is a corn seed height measuring device, which mainly consists of two parts: an industrial camera measuring instrument 1 and an intermittent conveying device 2. The industrial camera measuring instrument 1 is responsible for accurately measuring the height of the corn seeds, while the intermittent conveying device 2 is responsible for sequentially and accurately conveying the corn seeds onto the platform of the industrial camera measuring instrument 1 to achieve batch measurement.

[0031] The industrial camera measuring instrument 1 consists of key components such as a stage, support, industrial camera, and supplementary light, and is used with professional industrial standard measurement software. This software is existing technology and will not be described in detail here. The software can automatically process the captured images of corn seeds and accurately measure the vertical distance from the base (radicle end) to the top (germinate end), i.e., the seed height. The measurement accuracy is as high as 0.1mm, fully meeting the accuracy requirements for corn seed height measurement.

[0032] The intermittent conveying device 2 is the core part of this device. It consists of a fan-shaped seed feeding tray 3, a seed feeding tray guide plate 4, and a servo motor 5, and is responsible for the intermittent conveying of corn seeds.

[0033] The fan-shaped seed delivery tray 3 includes a fan-shaped plate 31 with an angle range of 225°-240°. A shaft hole 32, which mates with the output shaft of the servo motor 5, is provided at the center of the fan-shaped plate 31, ensuring stable rotation of the fan-shaped plate 31 under the drive of the servo motor 5. A triangular groove 33 is provided at one end of the fan-shaped plate 31, with a first bevel 34 at the upper end of the triangular groove 33 to facilitate the smooth delivery of corn seeds; a second bevel 35 is provided at the other end to push the measured corn seeds off the platform when rotating in the reverse direction.

[0034] The seed delivery tray guide plate 4 is designed with a side-opening fan-shaped plate compartment 41 for holding the fan-shaped plate 31. The opening end of the fan-shaped plate compartment 41 is flat, and its inner bottom surface is flush with the surface of the stage of the industrial camera measuring instrument 1, ensuring that the corn seeds can be smoothly transferred from the seed delivery tray guide plate 4 to the stage. The fan-shaped plate compartment 41 has a through hole 42 for the output shaft of the servo motor 5 to pass through; at the same time, a funnel 43 is also fixed through the fan-shaped plate compartment 41, close to the opening end of the fan-shaped plate compartment 41, to facilitate the individual falling of the corn seeds. In addition, a first positioning protrusion 44 and a second positioning protrusion 45 are fixed below the opening end of the fan-shaped plate compartment 41, for locking onto both sides of the stage of the industrial camera measuring instrument 1, ensuring the stability and measurement accuracy of the device.

[0035] The servo motor 5 is mounted on the seed delivery tray guide plate 4, and its output shaft is connected to the shaft hole 32 in the center of the sector plate 31, driving the sector plate 31 to reciprocate.

[0036] In the actual measurement process, the servo motor 5 first drives the fan-shaped seed feeding tray 3 to rotate 180°. At this time, one end of the fan-shaped seed feeding tray 3 releases corn seeds from the funnel 43 into the fan-shaped hopper 41 and pushes them onto the platform of the industrial camera measuring instrument 1. Then, the servo motor 5 rotates in the opposite direction, driving the fan-shaped seed feeding tray 3 to rotate 180° in the opposite direction. During this process, one corn seed falls from the funnel 43 into the fan-shaped hopper 41, and the falling of corn seeds in the funnel 43 is stopped. At the same time, the industrial camera of the industrial camera measuring instrument 1 takes a picture of the corn seed on the platform and automatically measures its height using professional software. Subsequently, the other end of the fan-shaped seed feeding tray 3 pushes the measured corn seed out of the platform, completing the picture measurement process for one corn seed. By repeating this process, the height measurement of corn seeds can be completed in batches.

[0037] Industrial standard professional measurement software sequentially records the measured data of corn seeds. Operators can sort and organize the measurement data as needed, selecting corn seeds within a suitable length range for statistical classification. Subsequently, the corresponding seeds are taken from the manually sorted corn seeds for classification and cultivation, further verifying the relationship between relevant characteristics of corn seeds and height, and providing a scientific basis for corn breeding work.

[0038] Through the design and implementation of this corn seed height measurement device, we have achieved rapid, batch, and accurate measurement of corn seed height, providing strong technical support for corn breeding research.
