Description

Technical Field

[0001] This utility model belongs to the field of corn seed treatment technology, specifically relating to a low-temperature intervention treatment device for corn seeds before sowing. Background Technology

[0002] The core purpose of low-temperature intervention treatment before corn seed sowing is to activate the stress resistance mechanism inside the seed by simulating the natural low-temperature environment, thereby improving its germination ability and seedling survival rate under low-temperature conditions in the field.

[0003] In existing cryogenic treatment devices, seed accumulation can lead to uneven localized temperatures, specifically a temperature difference of 2-5°C between the inside and surface of the seed pile. Seeds in the central area may not have fully activated their cold-resistance mechanisms, while surface seeds may be damaged by excessively low temperatures. To ensure uniform temperature, frequent manual turning of the seeds is necessary, increasing labor intensity and increasing the risk of contamination. Furthermore, condensation easily forms in low-temperature environments; if not drained promptly, this exacerbates the risk of mold and rot. Utility Model Content

[0004] To overcome the problems of uneven local temperature caused by seed accumulation, frequent manual turning leading to high labor intensity and easy introduction of contamination, and the risk of mold and rot due to the inability to drain condensate in a timely manner during the low-temperature intervention process before corn seed sowing, this utility model provides a low-temperature intervention treatment device for corn seeds before sowing. The treatment chamber is equipped with layered partitions and a vibration motor to prevent excessive seed accumulation and ensure uniform low-temperature distribution. The inner wall is coated with a nano-hydrophobic coating and has a conical bottom to facilitate rapid drainage of condensate. Automated control adjusts the cooling capacity and vibration frequency based on temperature sensor feedback, reducing manual intervention and effectively solving the problems of uneven temperature, condensate retention, and cumbersome manual operation in low-temperature seed treatment. This improves the efficiency of cold-resistance mechanism activation and reduces the risk of mold.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A low-temperature intervention treatment device for corn seeds before sowing mainly includes a frame, a treatment box, a support frame, springs, a mounting frame, a vibration motor, an air cooler, a drain pipe, a temperature sensor, and a controller. The treatment box is fixedly installed on the frame, and the bottom of the frame is equipped with casters with locking devices to ensure the stability of the device during use. The treatment box has a hollow cavity structure, and the support frame is fixedly installed inside the cavity structure. Springs are installed above the four support legs of the support frame, and the mounting frame is elastically connected to the top of the support frame by springs. The mounting frame has ventilation holes around its perimeter and a water outlet on its bottom surface. The air cooler is installed on the side wall of the treatment box and communicates with the inside of the treatment box to regulate the low-temperature environment inside the treatment box. The drain pipe is installed at the bottom of the treatment box and communicates with the inside of the treatment box to drain condensate. A movable door with a handle is provided on the side wall of the treatment box for easy loading and unloading of seeds; an observation window is provided on the other side wall for real-time monitoring of the internal conditions. A temperature sensor is installed inside the processing chamber to detect the real-time temperature inside the chamber; a controller is installed on the outer wall of the processing chamber. The vibration motor, air cooler, and temperature sensor are electrically connected to the controller, which adjusts the cooling capacity of the air cooler and the vibration frequency of the vibration motor based on the feedback signal from the temperature sensor. The mounting frame is equipped with a sliding groove, and a layered partition plate passes through one end of the mounting frame and can be slidably installed in the sliding groove, and is fixed to the mounting frame by fastening bolts. Ventilation holes and water outlet holes are evenly distributed on the layered partition plate, dividing the interior of the mounting frame into at least two layers to reduce the thickness of seed accumulation and make the temperature distribution more uniform. The inner wall of the treatment box is coated with a nano-hydrophobic coating to reduce the adhesion rate of condensate and prevent moisture retention from adversely affecting the seeds. The overall structure of the treatment box is designed as a rectangle at the top and a cone at the bottom, with the cone angle of the bottom cone structure ranging from 30° to 60°, so that condensate can be collected into the drain pipe. The beneficial effects of this utility model are: The mounting frame of this invention is elastically connected to the support frame by springs. A vibration motor drives the mounting frame to vibrate regularly, preventing excessive seed accumulation. Combined with layered partitions, the seeds are placed in layers, further reducing the thickness of each layer. This allows the low-temperature environment to act evenly on each seed, eliminating the temperature difference between the inside and surface of the seed pile and ensuring that each seed is fully exposed to the low-temperature environment, activating its cold-resistance mechanism. The inner wall of the treatment chamber is coated with a nano-hydrophobic coating to reduce condensate adhesion. The bottom is designed with a conical structure with a cone angle ranging from 30° to 60°, facilitating the rapid flow of condensate to the drain pipe for discharge, preventing moisture retention that could lead to mold and rot.

Detailed Implementation

[0012] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0013] This utility model discloses a low-temperature intervention treatment device for corn seeds before sowing. The device mainly includes a frame 1, a treatment box 2, a support frame 3, a spring 4, a mounting frame 5, a vibration motor 6, an air cooler 7, a drain pipe 8, a temperature sensor 9, and a controller 10. The frame 1 has four casters 11 at its bottom, each equipped with a locking device. The casters 11 are bolted to the four corners of the bottom of the frame 1 for movement and positioning of the device. The treatment box 2 is fixedly installed on the upper part of the frame 1, and the two are securely connected by welding or bolts. The treatment box 2 has a hollow structure, and the internal space is used to hold the corn seeds to be treated. The top of the treatment box 2 is rectangular, and the bottom is designed with a conical structure with a cone angle ranging from 30° to 60° to facilitate the collection and drainage of condensate at the bottom.

[0014] The inner wall of the treatment chamber 2 is coated with a nano-hydrophobic coating, which evenly covers the inner surface of the treatment chamber 2 and reduces the adhesion rate of condensate. A movable door 15 is installed on one side wall of the treatment chamber 2, connected to the treatment chamber 2, and equipped with a handle 16 for easy loading and unloading of seeds. An observation window 17, made of transparent material, is installed on the other side wall and embedded in the side wall of the treatment chamber 2 and fixed with sealant for real-time monitoring of the internal conditions. A drain pipe 8 is installed at the bottom of the treatment chamber 2 to drain condensate.

[0015] The support frame 3 is fixedly installed inside the cavity structure of the treatment box 2. The bottom of the support frame 3 is fixed to the bottom plate of the treatment box 2 with bolts to ensure its stability and load-bearing capacity. Springs 4 are installed above the four support legs of the support frame 3, and the springs 4 are fixed to the support frame 3 by welding. The mounting frame 5 is elastically connected to the top of the support frame 3 by the springs 4. Ventilation holes are opened around the perimeter of the mounting frame 5, and water outlet holes are provided on the bottom surface. The ventilation holes are used to promote air circulation, and the water outlet holes are used to drain condensate.

[0016] The mounting frame 5 has an internal sliding groove 18, which is arranged laterally along the inner wall of the mounting frame 5. A layered partition 19 passes through one end of the mounting frame 5 and is slidably installed within the sliding groove 18. The layered partition 19 is fixed to the mounting frame 5 by fastening bolts 20, which pass through the partition 19 and are screwed into the threaded holes of the mounting frame 5 to secure the partition 19. Ventilation holes and drainage holes are evenly distributed on the partition 19 to further promote air circulation and condensate drainage. The partition 19 divides the interior of the mounting frame 5 into at least two layers, the height of which can be adjusted according to actual needs to reduce seed accumulation thickness.

[0017] A vibration motor 6 is fixedly installed on the bottom outer side of the mounting frame 5. The vibration motor 6 is connected to the mounting frame 5 by bolts. When the vibration motor 6 runs, it drives the mounting frame 5 to vibrate regularly, thereby preventing excessive seed accumulation. An air cooler 7 is installed on the side wall of the treatment chamber 2. The air inlet of the air cooler 7 is connected to the external environment, and the air outlet is connected to the interior of the treatment chamber 2, used to regulate the low-temperature environment inside the treatment chamber 2. The air cooler 7 is fixed to the side wall of the treatment chamber 2 by bolts, and the connection is sealed with sealant to ensure airtightness.

[0018] Temperature sensor 9 is installed inside processing chamber 2 and is fixed to the inner wall of processing chamber 2 with bolts. It is used to detect the real-time temperature inside processing chamber 2. Controller 10 is installed on the outer wall of processing chamber 2 and is fixed to the outer surface of processing chamber 2 with bolts. Vibration motor 6, air cooler 7, and temperature sensor 9 are electrically connected to controller 10 via wires. The wires are introduced into the processing chamber 2 through wire holes and connected to each component. Controller 10 adjusts the cooling capacity of air cooler 7 and the vibration frequency of vibration motor 6 according to the signal fed back by temperature sensor 9.

[0019] In practical use, the operator first loads corn seeds into the mounting frame 5 inside the processing chamber 2 through the movable door 15. The seeds are separated into multiple layers by the layered partitions 19, each layer being relatively thin to reduce the impact of seed accumulation on low-temperature distribution. After closing the movable door 15, the air cooler 7 is activated, starting to supply cold air into the processing chamber 2, gradually lowering the internal temperature. The temperature sensor 9 monitors the temperature changes inside the processing chamber 2 in real time and transmits the data to the controller 10. The controller 10 adjusts the cooling capacity of the air cooler 7 according to the preset temperature range to maintain a stable temperature inside the processing chamber 2.

[0020] Simultaneously, the vibration motor 6 starts and drives the mounting frame 5 to vibrate regularly. The vibration is transmitted to the mounting frame 5 through the spring 4, causing the seeds inside the mounting frame 5 to continuously turn over, avoiding uneven local temperature caused by seed accumulation. The presence of the layered partition 19 further reduces the thickness of a single layer of seeds, ensuring that the low-temperature environment can act evenly on each seed. During the low-temperature intervention process, the condensate generated on the inner wall of the treatment box 2 does not easily adhere due to the nano-hydrophobic coating, but instead flows along the inner wall to the bottom conical structure and is discharged through the water outlet and drain pipe 8, effectively preventing moisture retention that could lead to mold and rot.

[0021] Operators can monitor the inside of the treatment box 2 in real time through the observation window 17 and adjust the parameters of the controller 10 as needed. After the treatment is completed, the active door 15 is opened to take out the seeds, completing the low-temperature intervention treatment process. Throughout the process, the automated control system of the device significantly reduces the need for manual operation, avoids the pollution problem that may be caused by manual turning, and ensures the effect of low-temperature treatment of the seeds.

[0022] Work process: The operator first loads the corn seeds to be processed into the mounting frame 5 inside the processing chamber 2 through the movable door 15. During loading, the seeds are separated into multiple layers by the layered partitions 19. The height of each layer can be adjusted by sliding the partitions 19 along the slide grooves 18 and fixed in position by the fastening bolts 20. The evenly spaced ventilation holes and drainage holes on the partitions 19 ensure air circulation and condensate drainage, while reducing the thickness of a single layer of seeds to avoid uneven temperature distribution caused by excessive accumulation. After closing the movable door 15, the operator starts the air cooler 7. The air cooler 7 introduces and cools external air through the air inlet and then delivers the cold air into the processing chamber 2. As the cold air continues to be input, the temperature inside the processing chamber 2 gradually decreases. The temperature sensor 9 monitors the temperature changes inside the processing chamber 2 in real time and transmits the data to the controller 10. The controller 10 adjusts the cooling capacity of the air cooler 7 according to the preset low temperature range to keep the temperature inside the processing chamber 2 stable within the target range. Through the coordinated action of the air cooler 7 and the controller 10, precise temperature control is achieved, ensuring that the low temperature environment can evenly cover all seeds.

[0023] Simultaneously, the vibration motor 6 starts and drives the mounting frame 5 to vibrate regularly. The vibration is transmitted to the mounting frame 5 through the spring 4, causing the seeds inside the mounting frame 5 to continuously tumble. Due to the presence of the layered partition 19, the seeds are confined to a thin single-layer space. The vibration can more effectively prevent the seeds from piling up, thus solving the problem of uneven local temperature caused by seed accumulation in traditional devices. The nano-hydrophobic coating on the inner wall of the treatment chamber 2 reduces the adhesion rate of condensate. The generated condensate flows along the inner wall to the bottom conical structure and is discharged through the water outlet and drain pipe 8, effectively preventing condensate from stagnating inside the treatment chamber 2 and reducing the risk of mold and rot.

[0024] During the cryogenic intervention, operators can monitor the interior of the treatment chamber 2 in real time through observation window 17. Observation window 17 is made of transparent material, embedded in the side wall of the treatment chamber 2, and fixed with sealant to ensure both a clear view and the airtightness of the treatment chamber 2. If adjustments to the temperature or vibration frequency are needed, operators can set parameters through controller 10. Controller 10 automatically adjusts the cooling capacity of air cooler 7 and the vibration frequency of vibration motor 6 based on feedback signals, thereby optimizing the cryogenic intervention effect. After treatment, operators open the movable door 15 and remove the cryogenically treated seeds. The entire process eliminates the need for frequent manual handling of the seeds, significantly reducing labor intensity and preventing the introduction of external contamination.

[0025] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
