Description

Technical Field

[0001] This utility model relates to the technical field of crop seed and seedling testing devices, specifically a crop seed and seedling testing device. Background Technology

[0002] The quality of crop seeds directly affects the growth and yield of crops. To ensure seed quality, seed seedling testing is an indispensable step. Seed purity is an important indicator of seed quality. Seed purity can usually be determined by testing the morphological characteristics, color, and size of the seeds.

[0003] Currently, the purity of crop seeds is usually tested by manual visual inspection. However, this method relies on the operator's experience and is too labor-intensive due to the large number of seeds, resulting in low testing efficiency. Therefore, there is a need to propose a crop seed seedling testing device. Utility Model Content

[0016] 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.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a crop seedling detection device. (Refer to...) Figures 1-5 A crop seed seedling testing device includes an operating table 1, an industrial camera 21 mounted on one side of the top of the operating table 1, a testing mechanism 3 mounted on the top of the operating table 1 near the industrial camera 21, a controller 4 mounted on the top of the operating table 1 near the testing mechanism 3, a first dispensing bin 22 mounted on the side of the testing mechanism 3 near the industrial camera 21, and a second dispensing bin 23 mounted on the other side of the testing mechanism 3. By intermittently rotating the testing mechanism 3 in batches, crop seeds are transported to the area below the industrial camera 21. The industrial camera 21 uses visual technology to identify the morphological characteristics, color, and size of the seeds to determine whether the seeds are qualified. The controller 4 sets the seed qualification rate. Batches of seeds that fail the test by the industrial camera 21 are pushed into the first dispensing bin 22 by the testing mechanism 3, while qualified seeds are pushed into the second dispensing bin 23 during the next rotation interval, thereby improving the efficiency of crop seed purity testing. The testing mechanism 3 includes a turntable 31. A motor 32 is fixedly connected to the top of the operating table 1. The axis of the turntable 31 is fixedly connected to the output end of the motor 32. A tray 33 is rotatably connected to the top of the turntable 31. A guide tray 310 is fixedly connected to one side of the tray 33. A cylinder 34 is installed on one side of the tray 33. A photoelectric sensor 35 is installed at the bottom of the turntable 31. The turntable 31 is driven by the motor 32 to rotate intermittently. The turntable 31 drives the tray 33 and seeds to rotate sequentially to below the industrial camera 21. When the pass rate of the seeds detected by the industrial camera 21 reaches the pass rate set by the controller 4, the turntable 31 rotates to an interval. At this time, the photoelectric sensor 35 triggers a signal, and the cylinder 34 pushes one end of the tray 33 to flip upward, so that the seeds pass through the guide tray 310. The tray 310 falls into the second distribution bin 23. If the pass rate detected by the industrial camera 21 is lower than the pass rate set by the controller 4, the cylinder 34 on one side of the tray 33 will push it upward and flip it to push the seeds into the first distribution bin 22, thereby achieving the effect of efficient detection of seed purity. The photoelectric sensor 35 used in this embodiment is a through-beam photoelectric sensor. The photoelectric detection device is composed of a separate transmitter and receiver. It achieves non-contact object detection by blocking the light beam. It is widely used in industrial automation, logistics sorting and environmental monitoring. Its transmitter uses a light-emitting diode or laser diode to emit red light or infrared light. The receiver converts the light signal into an electrical signal through a photoelectric element. The detection distance can reach tens of meters.

[0018] Reference Figure 1 , Figure 2 and Figure 3 A fixed frame 38 is fixedly connected to the top of the operating table 1. A turntable 31 is rotatably connected to the top of the fixed frame 38. A photoelectric receiver 37 is fixedly connected to one end of the top of the fixed frame 38 near the second dispensing bin 23. A photoelectric transmitter 36 is fixedly connected to the bottom of the turntable 31 near the tray 33. A support plate 39 is fixedly connected to one side of the tray 33. A cylinder 34 is rotatably connected to one side of the support plate 39 via its telescopic shaft. The other end of the cylinder 34 is rotatably connected to the top of the turntable 31. A fixed rod 2 is fixedly connected to the top of the operating table 1. An industrial camera 21 is fixedly connected to the top of the fixed rod 2. The turntable 31 is driven to rotate intermittently by a motor 32. The turntable 31 rotates stably on the fixed frame 38. The rotation of the turntable 31 causes the tray 33 and seeds to rotate sequentially to the area below the industrial camera 21. Seeds that meet the purity test pass rate are carried by the turntable 31 into the next rotation interval. At this time, the photoelectric receiving end 37 on the fixed frame 38 and the photoelectric emitting end 36 at the bottom of the turntable 31 are exactly opposite each other. The cylinder 34 on one side of the tray 33 drives one end of the tray 33 to rotate through the support plate 39. One end of the tray 33 flips upward, so that the seeds on the tray 33 roll into the second dispensing bucket 23 through the guide plate 310, thereby separating the seeds that meet the purity test rate.

[0019] Reference Figure 4 and Figure 5A fixed sleeve 311 is fixedly connected to the top of the turntable 31, and a positioning rod 312 is fixedly connected to the bottom of the tray 33. The positioning rod 312 is inserted into the inner cavity of the fixed sleeve 311. A first magnetic block 313 is fixedly connected to the bottom of the inner cavity of the fixed sleeve 311, and a second magnetic block 314 is fixedly connected to the bottom of the positioning rod 312. The first magnetic block 313 and the second magnetic block 314 are magnetically connected. The tray 33 rotates on the turntable 31 with one end located on it, and the other end of the tray 33 is kept horizontal through the cooperation of the positioning rod 312 and the fixed sleeve 311. The cooperation of the first magnetic block 313 and the second magnetic block 314 allows the tray 33 to be stably suspended horizontally during the reciprocating flipping process.

[0020] Working principle: In use, seeds are loaded into the tray 33 of the testing mechanism 3 in batches. The seed purity test pass rate is preset by the controller 4 on the operating table 1. The turntable 31 is driven by the motor 32 to rotate on the fixed frame 38. The industrial camera 21 on the fixed rod 2 detects the seeds on the tray 33 in turn. If the seed purity pass rate does not meet the standard, the cylinder 34 on one side of the tray 33 pushes the support plate 39. The support plate 39 causes one end of the tray 33 to flip upward on the turntable 31, so that the seeds with unqualified purity are discharged from the guide tray. 310 seeds fall into the first distribution bin 22. When the seed purity meets the standard, the turntable 31 rotates and enters the next interval. At this time, the photoelectric transmitter 36 and the photoelectric receiver 37 of the photoelectric sensor 35 are exactly aligned. The cylinder 34 on one side of the tray 33 pushes the tray 33 to flip, so that the seeds with qualified purity on the tray 33 fall into the second distribution bin 23. During the up-and-down flipping process of the tray 33, the first magnetic block 313 in the inner cavity of the fixing sleeve 311 and the second magnetic block 314 at the bottom of the positioning rod 312 always cooperate to keep the tray 33 horizontally suspended.
