Description

Technical Field

[0001] The utility model relates to the technical field of seedling raising devices, in particular to a seedling raising device for corn cultivation. Background Art

[0002] As an important food crop and feed source, corn plays a crucial role in agricultural production. The corn cultivation process has relatively strict requirements for environmental conditions. A good seedling raising environment is the key to ensuring the healthy growth of corn seedlings, improving the yield and quality of corn. In traditional corn cultivation, the seedling raising devices used are usually relatively simple. These devices generally consist of simple seedling raising boxes, with basic soil and watering facilities inside.

[0003] However, traditional seedling raising devices have many defects. In terms of temperature control, the stability is poor. Due to the lack of an accurate temperature control mechanism, when it is necessary to raise or lower the temperature of the seedling raising environment, the temperature is likely to fluctuate greatly. Such drastic temperature fluctuations are extremely unfavorable to the growth of corn seedlings, and may lead to slow growth, poor development, or even death of the seedlings.

[0004] In terms of soil air permeability, traditional seedling raising devices also have deficiencies. Most devices do not have a specially designed ventilation structure, resulting in insufficient oxygen supply in the soil, affecting the respiration of the roots of corn seedlings, and thus hindering the normal growth and development of the seedlings.

[0005] In summary, traditional seedling raising devices for corn cultivation have obvious defects in terms of temperature control stability and soil air permeability, and cannot meet the needs of modern corn cultivation, and urgently need to be improved and innovated. Content of the Utility Model

[0034] The following further elaborates on the present utility model in conjunction with the drawings.

[0035] Combined with the attached Figure 1 to the attached Figure 7 A seedling raising device for corn cultivation includes a cultivation box 1 with an open upper end. A sprinkler irrigation assembly 3 is fixedly provided at the upper end of the cultivation box 1 through a bracket 2.

A hot water circulation pipeline 9 is fixedly provided inside the heating box 8, and a circulating heating assembly 10 communicated with the hot water circulation pipeline 9 is fixedly provided outside the heating box 8.

[0036] The working principle of the seedling raising device for corn cultivation of the present utility model is as follows: The seedling raising device for corn cultivation monitors the temperature and humidity inside the cultivation box 1 in real time through the temperature sensor 4 and the humidity sensor 5. When the temperature is lower than the set value, the PLC controller 15 starts the circulating heating assembly 10. The water in the water tank 11 circulates in the heating box 8 through the hot water circulation pipeline 9 under the action of the circulating water pump 12. The metal heat conduction plate 16 absorbs heat and evenly conducts the heat into the cultivation box 1. At the same time, the electric heating plate 13 and the temperature sensor two 14 cooperate to keep the water temperature in the water tank 11 constant, so as to achieve a stable heating effect. In terms of humidity, the atomizing nozzles 21 in the sprinkler irrigation assembly 3 perform precise sprinkler irrigation under the water supply of the external water supply pump and the control of the PLC controller 15 to maintain an appropriate humidity. The ventilation holes 6 and the waterproof and breathable membrane 7 at the bottom of the cultivation box 1 ensure the air permeability of the soil, and the circulating fan 18 promotes air circulation to further optimize the cultivation environment.

[0037] Reference appendix Figure 2 , the circulating heating assembly 10 includes a water tank 11 fixedly arranged on the outer side surface of the heating box 8. A circulating water pump 12 is communicated and arranged on the side surface of the water tank 11. The water outlet end of the circulating water pump 12 is communicated with the hot water circulation pipeline 9. The other end of the hot water circulation pipeline 9 is communicated with the water tank 11. A constant temperature control assembly is arranged in the water tank 11. The constant temperature control assembly includes an electric heating plate 13 and a temperature sensor II 14 fixedly arranged on the side wall of the water tank 11, and further includes a PLC controller 15 fixedly arranged on the front surface of the water tank 11. The electric heating plate 13, the temperature sensor II 14, the temperature sensor 4 and the humidity sensor 5 are all electrically connected to the PLC controller 15 and are programmed and controlled by the PLC controller 15.

[0038] Reference appendix Figure 6 , a metal heat conducting plate 16 is fixedly arranged on the inner top surface of the heating box 8. Heat preservation plates 17 are fixedly arranged on the inner bottom surface and the side surfaces of the heating box 8. A circulating fan 18 is fixedly arranged at the center of the inner bottom surface of the heating box 8. Self-locking universal wheels 19 are fixedly arranged at the four corners of the bottom of the heating box 8.

[0039] Reference appendix Figure 2 , the sprinkler irrigation assembly 3 includes an atomizing pipeline 20 fixedly arranged at the upper end of the support 2. A plurality of atomizing nozzles 21 are arranged at the bottom of the atomizing pipeline 20. The atomizing pipeline 20 is communicated with an external water supply water pump through a hose. The external water supply water pump is electrically connected to the PLC controller 15.

[0040] The working process of a seedling raising device for corn cultivation of the present utility model is as follows:

[0041] 1. Preparation stage: First, clean and disinfect the cultivation box 1 and the heating box 8 to ensure that there is no residual germ. Evenly spread the fertile soil prepared in advance and suitable for the growth of corn in the cultivation box 1. Sow the corn seeds in the soil according to the appropriate planting density and depth. Check whether the atomizing pipeline 20 and the atomizing nozzles 21 of the sprinkler irrigation assembly 3 are normal to ensure no blockage.

[0042] 2. Set parameters: Through the operation interface of the PLC controller 15, input the suitable temperature range for the growth of corn seedlings, such as 20-25 °C. Similarly, set the appropriate humidity range on the PLC controller 15, such as 60%-70%.

[0043] 3. Start the device: Turn on the main power switch of the device to make each component of the device enter the standby working state. At this time, the temperature sensor 4, the humidity sensor 5, the circulating heating assembly 10, the sprinkler irrigation assembly 3, etc. start the initialization work.

[0044] 4. Temperature Regulation: The temperature sensor 4 monitors the temperature inside the incubator 1 in real time and transmits the data to the PLC controller 15. When the temperature is lower than the set lower limit value, such as 20 °C, the PLC controller 15 activates the circulating heating component 10. The circulating water pump 12 starts to work, pumping the hot water in the water tank 11 into the hot water circulation pipeline 9 for circulating flow inside the heating box 8. The metal heat conduction plate 16 quickly conducts the heat evenly into the incubator 1 to raise the temperature inside the box. The electric heating plate 13 and the temperature sensor 2 14 work together to ensure that the water temperature in the water tank 11 always remains within a constant range, thus providing a stable heat source for the incubator 1. When the temperature reaches the set upper limit value, such as 25 °C, the PLC controller 15 controls the circulating heating component 10 to stop working and maintains the current temperature stable.

[0045] 5. Humidity Regulation: The humidity sensor 5 monitors the humidity inside the incubator 1 in real time and feeds back the data to the PLC controller 15. When the humidity is lower than the set lower limit value, such as 60%, the PLC controller 15 activates the external water supply pump to supply water to the atomization pipeline 20 through a hose. The atomization nozzle 21 sprays out fine water mist to evenly irrigate the inside of the incubator 1, increasing the air humidity and soil humidity. When the humidity reaches the set upper limit value, such as 70%, the PLC controller 15 controls the external water supply pump to stop working and stops the irrigation.

[0046] 6. Daily Observation: Regularly observe the growth of corn seedlings every day, including the germination rate of seeds, the height of seedlings, the color and shape of leaves, etc. Check the moisture content and air permeability of the soil. If necessary, appropriately adjust the irrigation frequency and time, or manually loosen the soil to enhance air permeability. Check the operation status of the equipment, such as whether there is water leakage, abnormal noise, etc.

[0047] 7. Mobile Equipment: When it is necessary to move the equipment to other locations, unlock the self-locking universal wheels 19. Carefully push the equipment to the target position, paying attention to avoiding collisions and bumps, so as not to affect the growth of corn seedlings. After reaching the designated position, re-lock the self-locking universal wheels 19 to ensure the stability of the equipment.

[0048] 8. Cultivation Completion: Wait until the corn seedlings grow to a stage suitable for transplanting or subsequent processing, such as having 3 - 4 true leaves. Carefully take out the corn seedlings from the incubator 1, paying attention to protecting the roots of the seedlings. Clean and maintain the incubator 1 to prepare for the next round of seedling cultivation.

[0049] The above description is made on the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the gist of the creation of the present utility model, design similar structural modes and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
