Description

Technical Field

[0001] This utility model relates to the field of seed drought resistance testing technology, specifically a testing device for the drought resistance of maize seeds. Background Technology

[0002] A corn seed is a reproductive organism capable of growing into a mature corn plant. It is formed from the ovule through pollination and fertilization. A corn seed mainly consists of three parts: the seed coat, the embryo, and the endosperm. Due to the perennial drought in some parts of my country, drought resistance testing equipment is needed to determine whether corn seeds can be planted and grown normally in arid areas.

[0003] A search revealed patent application CN202022924069.7, which discloses a device for testing the drought resistance of peanut seeds. The device includes a test chamber, with its bottom connected to a base and its front hinged to a door. An inner sleeve mechanism is installed inside the chamber, and a through-hole is located at the top. A detection head is mounted on the test chamber, extending through the through-hole into the chamber. This device features a detection head with a temperature and humidity sensor mounted on its port, positioned above a support mesh. The sensor data is recorded. An insulation layer provides insulation for the interior of the test chamber. The mesh has a smaller aperture than the peanut seed diameter. Peanut seeds are placed on the mesh, and a heating element driven by a circuit board heats the mesh, thus drying the peanut seeds. The resulting high-temperature environment affects the peanut seeds.

[0004] However, this patent has its shortcomings. In actual use, the seed drought resistance test device mainly dries the seeds by placing them on a tray and then using a circuit board to drive a heating element to heat the tray. However, because the seeds are stacked and stationary on the tray, some seeds cannot fully contact the heat, which can easily lead to incomplete drying and affect the test quality. In addition, after drying, the seeds need to be manually picked up from the tray using a shovel or by hand, which takes a long time and is not convenient to use.

[0005] To address this, we propose a testing device for the drought resistance performance of maize seeds. Utility Model Content

[0023] Please see Figures 1 to 4This utility model provides a testing device for the drought resistance performance of corn seeds, including a test chamber 2. A U-shaped cover 4 is inserted into the front end of the test chamber 2. The rear end of the U-shaped cover 4 extends into the test chamber 2 and abuts against the inner wall of the rear end of the test chamber 2. A rotating tube 7 is rotatably connected inside the test chamber 2 and located inside the U-shaped cover 4. Multiple feed paddles 9 are fixedly installed on the outside of the rotating tube 7. Multiple air vents 8 are provided on the outside of the rotating tube 7. A feed pipe 3 is fixedly installed at the top of the test chamber 2. A temperature sensor 12 is fixedly installed at the left side of the feed pipe 3 at the top of the test chamber 2. A humidity sensor 13 is fixedly installed at the right side of the feed pipe 3 at the top of the test chamber 2. A bracket 14 is fixedly installed at the rear end of the test chamber 2. A hot air blower 15 is fixedly installed at the rear end of the bracket 14. A toothed ring 17 is fixedly sleeved on the outer side of the rear end of the rotating tube 7. A gear 18 is meshed with the right side of the toothed ring 17.

[0024] Multiple air outlets 8 and multiple material feeding plates 9 are spaced apart on the rotating tube 7. This design facilitates the use of the equipment. A conveying pipe 16 is fixedly installed at the front end of the hot air blower 15. The front end of the conveying pipe 16 is rotatably connected inside the rotating tube 7, facilitating the delivery of hot air into the rotating tube 7. A motor 19 is fixedly installed at the rear end of the bracket 14, located on the right side of the hot air blower 15. The output end of the motor 19 is fixedly installed on the gear 18. The motor 19 drives the gear 18 to rotate, which is beneficial to the use of the equipment. Clips 10 are fixedly installed on both sides of the U-shaped cover 4. Inside the test chamber 2, there are slots 11 at each of the two corresponding clips 10. The clips 10 are engaged in the slots 11, and the U-shaped cover 4 can be limited by the clips 10. A handle 5 is fixedly installed at the front end of the U-shaped cover 4, which makes it easy to pull the U-shaped cover 4. A PLC controller 20 is fixedly installed on the right side of the test chamber 2, which makes it easy to control the operation of this equipment.

[0025] Working principle: During use, the corn seeds to be tested are poured into the U-shaped cover 4 through the feed pipe 3. The drying switch is turned on, and the hot air blower 15 delivers hot air to the rotating pipe 7, which is then blown out through multiple air outlets 8. At the same time, the motor 19 drives the gear 18, gear ring 17, rotating pipe 7, and multiple feed paddles 9 to rotate. The feed paddles 9 agitate the corn seeds, ensuring they are fully exposed to the hot air for drying. The temperature sensor 12 and humidity sensor 13 monitor the temperature and humidity inside the test chamber 2 in real time. After drying, the receiving container is placed under the guide hopper 6, and the U-shaped cover 4 and the feed hopper 6 are closed using the pull handle 5. When the two clips 10 are pulled out, the bottom of the corn seeds loses support and can quickly fall from the feed hopper 6 into the receiving container. The staff can then check the condition of the dried corn seeds in the receiving container to determine their drought resistance. This corn seed drought resistance testing device is easy to use. The above components can turn the corn seeds during the drying process, allowing them to come into uniform contact with the hot air for drying, thereby further improving the drying effect. At the same time, the corn seeds can be quickly removed after drying, saving material removal time and further improving the convenience of using this equipment.
