Description

Technical Field

[0001] This utility model relates to the field of seedling propagation technology, specifically a dry heat sterilization device for seedling propagation seeds. Background Technology

[0002] Seedling propagation refers to the use of a series of technical means to increase the quantity and efficiency of seedling propagation in order to meet the needs of landscaping, ecological restoration, agricultural production, and other fields. Methods of seedling propagation mainly include sowing, cutting, division, and grafting.

[0003] Among these methods, seed propagation is one of the most common. Seeds are collected, sown, and after a period of cultivation, new seedlings are formed. Seed treatment mainly includes sun-drying, disinfection, and germination. Sun-drying kills bacteria and fungi on the seed surface, reducing the occurrence of diseases; disinfection prevents seeds from being affected by pests and diseases before sowing. Most existing dry heat sterilization equipment uses a trolley system for loading and unloading. The uneven heating of the bottom and middle support trays within the chamber affects the effectiveness of dry heat sterilization. Utility Model Content

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0021] Please see Figures 1 to 7 As shown in the embodiment of this application, a dry heat sterilization device for seed propagation of seedlings is provided, including a dry heat sterilization chamber 1 and a set of sealed doors 2 hinged to the front end of the dry heat sterilization chamber 1. A chain lifting mechanism is provided inside the dry heat sterilization chamber 1. The chain lifting mechanism includes a set of drive motors 3, a set of drive shafts 4, a set of driving chain teeth 5, a set of driven shafts 6, a set of driven chain teeth 7, a set of staggered transmission chains 8, several sets of staggered sprockets 9, and several bearing seats 10. A set of drive motors 3 are alternately installed on both sides of the bottom of the dry heat sterilization chamber 1, and a set of drive shafts 4 are installed on a set of drive motors 3. On the rotating end of motor 3, and respectively movably inserted into the bottom two sides of dry heat sterilizer 1 through fastening bearings, a set of driving chain teeth 5 is installed at the front end of a set of drive shafts 4, a set of driven shafts 6 are alternately installed on the top two sides of dry heat sterilizer 1 through fastening bearings, a set of driven chain teeth 7 is installed at the front end of a set of driven shafts 6, a set of misaligned transmission chains 8 are respectively fitted on the opposite set of driving chain teeth 5 and driven chain teeth 7, several sets of misaligned sprockets 9 are evenly installed on a set of misaligned transmission chains 8, and several bearing seats 10 are respectively hinged between the opposite set of misaligned sprockets 9.

[0022] In this embodiment, during use, the user first places the seeds requiring dry heat sterilization into several carrier seats 10 via a placement tray. A set of drive motors 3 work synchronously, driving a set of active chain teeth 5 to rotate via a set of drive shafts 4. This, in conjunction with a set of driven shafts 6 and a set of driven chain teeth 7, drives a set of staggered transmission chains 8 to rotate synchronously. The staggered transmission chains 8 are arranged at different heights and, through several sets of staggered sprockets 9, can drive several carrier seats 10 to continuously and cyclically lift. The staggered arrangement of the staggered sprockets 9 relative to the carrier seats 10 and their respective hinges ensures the balance of the carrier seats 10. The time difference during rotation provides better stability, and the front side always faces upward during lifting. Combined with the heating mechanism inside the dry heat sterilization chamber 1, this allows the seeds in the placement tray to be heated more evenly, improving the dry heat sterilization effect, reducing the occurrence of diseases, and effectively promoting seedling propagation to meet the needs of landscaping, ecological restoration, and agricultural production.

[0024] and combined Figure 1 As shown, external air can enter the dry heat sterilization chamber 1 through a set of air inlet mesh covers 11. With the help of a set of fans 12 and a circulating air duct 13, air circulation is achieved in the dry heat sterilization chamber 1, and the heating device can heat the air.

[0025] In some embodiments, the heating device employs steam heating or electric heating.

[0026] In some embodiments, a temperature and humidity sensor 14 is installed on the top of the dry heat sterilizer 1. The temperature and humidity sensor 14 can be used to monitor the temperature and humidity signals inside the dry heat sterilizer 1 and transmit the signals to the controller to control the heating device to turn on and off.

[0027] In some embodiments, a plurality of support seats 10 each include a support plate 15 and a support frame 16 mounted on the bottom of the support plate 15.
