Description

Technical Field

[0001] This utility model relates to the field of seed germination equipment technology, and in particular to an integrated machine for soaking and germinating seeds. Background Technology

[0002] Seed soaking and germination is an agricultural technique mainly used to promote the rapid and uniform germination of seeds. Seeds are soaked in clean water or a specific solution to allow them to absorb water and swell, softening the seed coat and activating internal physiological activities to prepare for germination. The soaking time varies depending on the type of seed, usually ranging from a few hours to tens of hours. After soaking, the seeds are placed under suitable temperature, humidity and ventilation conditions to promote germination.

[0003] Temperature is one of the key factors in seed germination. Inaccurate temperature control significantly affects the seed's water absorption rate and germination rate. Insufficient temperature control precision can lead to uneven germination, or even "scorched seeds" or "rotten sprouts." Traditional germination methods rely on natural conditions or simple incubators, resulting in long cycles and low success rates. Existing germination equipment often uses resistance wire heating and mechanical humidity control, which are complex in structure and energy-intensive. Furthermore, current germination equipment lacks nutrient supply equipment, leading to insufficient circulation of the soaking solution and insufficient oxygen in the water. Insufficient oxygen in the water affects the seed's aerobic respiration, preventing germination in water.

[0004] To address the aforementioned shortcomings, we offer an integrated seed soaking and germination machine. Utility Model Content

[0005] The purpose of this utility model is to propose an integrated machine for soaking and germinating seeds in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a seed soaking and germination integrated machine, including a water tank, a cover plate placed on the water tank, and a water outlet pipe installed on the side of the water tank. An equipment box is installed on the side of the water tank, and a circulating water pipe is fixed on the side of the water tank. A water pump that operates the circulating water pipe is installed in the equipment box. A temperature monitoring and control mechanism and an oxygenation control mechanism are provided in the equipment box. A mesh frame is provided in the water tank, as well as a lifting mechanism for controlling the vertical sliding of the mesh frame.

[0007] Preferably, a PLC controller is installed on the equipment box.

[0008] Preferably, the temperature monitoring and control mechanism includes a temperature sensor installed in the water tank and a heating device installed on the side of the equipment box. The signal output terminal of the temperature sensor is electrically connected to the signal input terminal of the PLC controller, and the signal output terminal of the PLC controller is electrically connected to the signal input terminal of the heating device.

[0009] Preferably, the heating device is a semiconductor heater.

[0010] Preferably, the oxygenation control mechanism includes an aeration pipe laid in the water tank, a blower installed in the equipment box, an air supply pipe connecting the output end of the blower to the aeration pipe, and the signal output end of the blower being electrically connected to the signal input end of the PLC controller.

[0011] Preferably, the bottom of the water tank is fixed with a support plate that is raised and placed to cooperate with the mesh frame.

[0012] Preferably, the lifting mechanism includes a shaft rotatably connected in a water tank, a drive motor for controlling the rotation of the shaft is installed at the outer end of the water tank, two transmission arms are coaxially fixed on the outer side of the shaft, and a bracket with two corresponding transmission arms is slidably connected in the water tank, with the free end of the transmission arm rotatably connected to the bracket.

[0013] Preferably, the transmission arm is composed of two arms of equal length rotatably connected, two strip blocks are fixed on the bracket, and a strip groove is formed in the inner wall of the water tank to cooperate with the vertical sliding of the strip blocks.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. In this application, a high-precision closed-loop control of the temperature in the water tank is achieved by using a PLC controller combined with a temperature sensor and a semiconductor heater, ensuring that the temperature is stable within the set range, effectively improving the seed germination rate and seedling uniformity. At the same time, the high efficiency of the semiconductor heater combined with the circulation system optimizes energy consumption and improves germination efficiency and quality.

[0016] 2. In this application, the coordinated design of the oxygenation control mechanism and the lifting mechanism enables precise control of dissolved oxygen levels in the water tank and automated lifting and lowering of the mesh frame. The oxygenation system uses a blower and aeration pipes to evenly deliver oxygen to the water, meeting the oxygen requirements for seed germination and preventing incomplete or failed germination due to oxygen deficiency. Meanwhile, the lifting mechanism uses a drive motor and transmission arm to achieve smooth lifting and lowering of the mesh frame, reducing manual intervention, improving the automation level of the equipment and the efficiency of seed loading and unloading, and significantly enhancing the convenience and overall efficiency of the germination operation.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a seed soaking and germination integrated machine, including a water tank 1, a cover plate 20 placed on the water tank 1, and a water outlet pipe 9 installed on the side of the water tank 1. An equipment box 2 is installed on the side of the water tank 1, and a circulating water pipe 4 is fixed on the side of the water tank 1. A water pump 6 that operates the circulating water pipe 4 is installed in the equipment box 2. A temperature monitoring and control mechanism and an oxygenation control mechanism are provided in the equipment box 2. A mesh frame 14 is provided in the water tank 1, and a lifting mechanism for controlling the vertical sliding of the mesh frame 14 is provided.

[0026] Water tank 1 is the core component of the integrated seed soaking and germination machine, used to hold the soaking solution and seeds. A cover plate 20 is installed on top of water tank 1 to seal it, preventing heat loss and external contamination. A water outlet pipe 9 is used to drain the soaking solution from water tank 1, facilitating cleaning and maintenance of the equipment. Equipment box 2 is installed on the side of water tank 1, used to install core components such as water pump 6, temperature monitoring and control mechanism, and oxygenation control mechanism.

[0027] The circulating water pipe 4 and water pump 6 are used to circulate the soaking solution, ensuring uniform water temperature distribution. This circulation effectively improves germination efficiency and quality. Furthermore, the circulation system can be combined with a temperature monitoring and control mechanism to heat the soaking solution. This mechanism is a key component for precise germination; it uses a temperature sensor 7 to monitor the temperature in the water tank 1 in real time and adjusts the heating device 5 through the control system to ensure the temperature remains within the set range. This temperature control method effectively improves the germination rate and seedling uniformity. The oxygenation control mechanism increases the dissolved oxygen content in the water tank 1 by supplying external air, meeting the oxygen requirements of the seeds during soaking and germination. The mesh frame 14 is used to hold the seeds, and the lifting mechanism controls the vertical sliding of the mesh frame 14, facilitating seed soaking and germination operations. This design allows for rapid loading and unloading of seeds, improving equipment efficiency.

[0028] Specifically, such as Figures 1-4 As shown, a PLC controller 3 is installed on the equipment box 2. The temperature monitoring and control mechanism includes a temperature sensor 7 installed in the water tank 1 and a heating device 5 installed on the side of the equipment box 2. The signal output terminal of the temperature sensor 7 is electrically connected to the signal input terminal of the PLC controller 3, and the signal output terminal of the PLC controller 3 is electrically connected to the signal input terminal of the heating device 5. The heating device 5 is a semiconductor heater.

[0029] Temperature sensor 7 monitors the temperature inside water tank 1 in real time and transmits the data to PLC controller 3.

[0030] The PLC controller 3 compares the preset temperature value with the actual measured value and calculates the heating power using a PID control algorithm. The PLC controller 3 sends a control signal to the heating device 5 (semiconductor heater) to adjust the heating power and keep the temperature in the water tank 1 within the set range.

[0031] Through this closed-loop control method, the system can achieve high-precision temperature control, ensuring that seeds are soaked and germinated under suitable temperature conditions.

[0032] Specifically, such as Figure 4 and Figure 5 As shown, the oxygenation control mechanism includes an aeration pipe 12 laid in the water tank 1, a blower 10 installed in the equipment box 2, an air supply pipe 11 connecting the output end of the blower 10 and the aeration pipe 12, and the signal output end of the blower 10 being electrically connected to the signal input end of the PLC controller 3.

[0033] After the blower 10 starts, air is delivered to the aeration pipe 12 through the air supply pipe 11. The aeration pipe 12 releases the air into the water tank 1 in the form of microbubbles. As the microbubbles rise, they come into full contact with the water, increasing the dissolved oxygen content in the water. The PLC controller 3 controls the operating frequency and power of the blower 10 according to the preset dissolved oxygen requirements, ensuring that the dissolved oxygen content in the water tank 1 is always maintained at a level suitable for seed germination.

[0034] Specifically, such as Figure 3 and Figure 4 As shown, a support plate 13 is fixedly installed at the bottom of the water tank 1 to support the lifting frame 14. The lifting mechanism includes a shaft 8 rotatably connected in the water tank 1. A drive motor 18 for controlling the rotation of the shaft 8 is installed at the outer end of the water tank 1. Two transmission arms 17 are coaxially fixed on the outer side of the shaft 8. Two brackets 15 corresponding to the transmission arms 17 are slidably connected in the water tank 1. The free ends of the transmission arms 17 are rotatably connected to the brackets 15.

[0035] The transmission arm 17 is composed of two arms of equal length connected by rotation. Two strip blocks 16 are fixed on the bracket 15. A strip groove 19 is formed in the inner wall of the water tank 1 to cooperate with the vertical sliding of the strip blocks 16.

[0036] The support plate 13 is fixed to the bottom of the water tank 1 to support the mesh frame 14, allowing it to be raised in its initial position. This prevents the seeds from contacting the bottom of the water tank 1 during soaking, reducing uneven germination caused by poor water flow or uneven temperature, and also facilitating seed loading and unloading. The outer side of the transmission arm 17 is coaxially fixed to the shaft 8. The rotation of the shaft 8 is controlled by the drive motor 18, allowing the transmission arm 17 to convert rotational motion into vertical sliding of the bracket 15. The bracket 15 is rotatably connected to the free end of the transmission arm 17, ensuring that it can slide up and down with the movement of the transmission arm 17. Two strip blocks 16 are fixed on the bracket 15, which cooperate with the strip grooves 19 on the inner wall of the water tank 1 to achieve vertical sliding.

[0037] The lifting and lowering of the mesh frame 14 is controlled by the drive motor 18, which reduces manual operation and improves the automation level of the equipment. The folding structure design of the transmission arm 17 makes the entire lifting mechanism occupy little space when not in operation, which is suitable for compact equipment layout. The cooperation of the strip block 16 and the strip groove 19 ensures the stability of the lifting and lowering process of the mesh frame 14 and avoids seeds from spilling.

[0038] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
