Description

Technical Field

[0001] The invention relates to the field of microorganisms and agricultural technology, in particular to a functional bacteria powder and a preparation method thereof. Background Art

[0002] With the development of modern agriculture, the excessive use of fertilizers and pesticides has led to a decline in soil quality, an imbalance in the structure of soil microbial communities, and reduced soil fertility. The introduction of beneficial agricultural bacteria can help restore soil health and improve soil fertility. Climate change and the frequent occurrence of pests and diseases pose severe challenges to crop growth. Beneficial agricultural bacteria can respond to these challenges by regulating plant growth and enhancing crop resistance, thereby ensuring crop yield and quality.

[0003] Bacillus subtilis is a kind of agricultural probiotics. Bacillus subtilis can promote the decomposition of soil organic matter, improve soil fertility and improve soil. Bacillus subtilis can improve seed germination and conservation rate, improve survival rate, promote root growth and prevent seed genetic diseases. Bacillus subtilis can also promote the release of soil trace elements and plant absorption, metabolize stimulating substances required for plant growth, promote crop growth, reduce costs, increase yields and increase income.

[0004] During the preparation process of the currently available Bacillus subtilis powder, the bacterial liquid needs to be dried to separate the Bacillus subtilis from the culture liquid. The Bacillus subtilis that is not fully dried will adhere to the inner wall of the powder preparation device, which is not conducive to the subsequent drying and collection operations. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a functional bacterial powder and a preparation method thereof, which drives the collecting bucket to vibrate through a first air pump, a connecting block, a coil spring, a ratchet, an eccentric wheel and a vibrating rod, so as to cause the bacterial liquid attached to the inner wall of the collecting bucket to slide off so as to be fully dried and collected.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a functional bacterial powder, a culture medium comprising 800-1000 parts of distilled water, 15-20 parts of glucose, 10-15 parts of peptone, 3-5 parts of yeast extract powder, 4-6 parts of sodium chloride and 18-20 parts of agar powder, and Bacillus subtilis is cultured in the culture medium.

[0007] The principle of the basic program is: provide carbon source through glucose, provide nitrogen source through peptone, provide inorganic salt through sodium chloride, provide coagulant through agar, and provide comprehensive and balanced nutrition for the cultivation of Bacillus subtilis through yeast extract powder.

[0008] The beneficial effects of the basic program are: 1. Provide comprehensive nutrition: Glucose, as the main carbon source, provides the necessary energy for the growth and metabolism of Bacillus subtilis. Peptone is rich in nitrogen and is the basis for the formation of biological macromolecules such as protein and nucleic acid in Bacillus subtilis cells. Sodium chloride not only provides the necessary sodium ions and chloride ions, but also participates in regulating the osmotic pressure of the culture medium, which is essential for maintaining the normal morphology and function of cells. Yeast extract powder provides comprehensive and balanced nutrition for the cultivation of Bacillus subtilis.

[0009] 2. This formula creates an optimal growth environment for Bacillus subtilis by precisely controlling the ratio of various nutrients. This optimized nutritional condition can significantly promote the growth rate of bacteria and improve the culture efficiency.

[0010] A method for preparing a functional bacterial powder comprises: step 1: preparing a powder preparation device for preparing Bacillus subtilis powder, wherein the powder preparation device is provided with a conveying component for conveying bacterial liquid, a spraying component for spraying the bacterial liquid, a drying component for drying the bacterial liquid, a collecting component for containing the bacterial liquid, a vibrating component for vibrating the collecting component, and a bacterial powder storage box for storing dry bacterial powder;

[0011] Step 2: placing the cultured bacterial solution on the conveying component, and conveying the bacterial solution to the spraying component through the conveying component;

[0012] Step 3: spray the bacterial solution through the spray component and spray it into the collection component;

[0013] Step 4: Drying and dehydrating the atomized bacterial liquid through a drying component;

[0014] Step 5: The drying component drives the vibration component to vibrate the collecting component, so that the undried bacterial liquid adhering to the collecting component falls off and then dries;

[0015] Step 6: The bacterial powder dried by the drying component is transported to a bacterial powder storage box for storage and subsequent use.

[0016] The beneficial effects of the basic scheme are: the bacterial powder is transported to the spray component through the conveying component, which is conducive to reducing the contamination of the bacterial liquid by the outside world; the spray component atomizes and sprays the bacterial liquid, which is conducive to increasing the overall surface area of ​​the bacterial liquid and improving the drying efficiency of the subsequent drying component for the bacterial liquid; the vibration component is conducive to shaking off the bacterial liquid attached to the collection component, so that the attached bacterial liquid can also be fully dried.

[0017] Furthermore, the powder preparation device includes a box body, a controller is fixedly connected to the box body, a drying component includes a first air pump, the first air pump is fixedly connected to the bottom wall of the box body, an air outlet of the first air pump is connected to a main air pipe, a heating wire is fixedly connected to the connection between the air outlet and the main air pipe, the heating wire is electrically connected to the controller, the main air pipe is connected to a first bronchial pipe, a vibration component includes a rotating column, a plurality of connecting blocks are fixedly connected to the outer circumference of the rotating column, grooves are provided in the connecting blocks, and the grooves are within the blowing range of the first bronchial pipe, one side of the rotating column is rotatably connected to the inner wall of the box body, the other side of the rotating column is fixedly connected to a connecting rod, and the other end of the connecting rod is fixedly connected to Ratchet, the ratchet outer shell is provided with an eccentric wheel, the eccentric wheel is provided with a toothed disk which cooperates with the ratchet wheel in one direction, a fixed rod is fixedly connected to the middle part of the eccentric wheel, and the other end of the fixed rod is rotatably connected to the box body, the collecting assembly includes a collecting bucket, the main air pipe is connected to the collecting bucket, the collecting bucket is fixedly connected to the inner wall of the box body, a vibrating rod is fixedly connected to the outer wall of the collecting bucket, the other end of the vibrating rod is in contact with the outer wall of the eccentric wheel, a coil spring is fixedly connected to the inner wall of the box body, and the other end of the coil spring is fixedly connected to the connecting rod, the rotating column is used to drive the connecting rod to rotate, the ratchet is used to stop the rotation of the eccentric wheel when the first air pump blows air through the first bronchus, and the ratchet drives the eccentric wheel to rotate when the energy stored in the coil spring is released.

[0018] The beneficial effects of the basic scheme are: the first air pump drives the connecting rod to rotate through the airflow, thereby storing energy in the coil spring, and releasing energy through the coil spring drives the ratchet to rotate; when the first air pump blows air into the first bronchus, the ratchet does not drive the eccentric wheel to rotate through the toothed disk, which is beneficial to reducing the energy loss of the coil spring; when the first air pump finishes blowing air into the first bronchus, the ratchet drives the eccentric wheel to rotate through the toothed disk, which is beneficial to improving the utilization efficiency of the energy stored in the coil spring; the hot air generated by the electric heating wire blown out by the first air pump is beneficial to drying the bacterial liquid in the collection bucket.

[0019] Furthermore, the conveying assembly includes a bacteria liquid conveyor, which is fixedly connected to one side of the top of the box body and is communicated with the spray assembly.

[0020] The beneficial effect of the basic solution is that the bacterial liquid conveyor is conducive to conveying the cultivated bacterial liquid to the spray component, reducing the contamination of the bacterial liquid during transportation.

[0021] Furthermore, the spray assembly includes an atomizer, which is fixedly connected to the top wall of the box body and is communicated with the bacterial liquid conveyor.

[0022] The beneficial effects of the basic solution are: the atomizer is conducive to atomizing the bacterial liquid and then spraying it out, and the total surface area of ​​the bacterial liquid atomization will increase significantly. Evaporation mainly occurs on the surface of the liquid, so the increase in surface area directly leads to an increase in the evaporation area, thereby accelerating the evaporation rate. The acceleration of the evaporation rate is conducive to improving the drying efficiency of the subsequent drying components.

[0024] The beneficial effects of the basic solution are: the second air pump is conducive to pressurizing the atomizer, and the bacterial liquid in the atomizer can be better atomized and dispersed through the second air pump, thereby improving the atomization efficiency of the atomizer.

[0025] Furthermore, the drying component also includes a second bronchus, which is connected to the main air pipe, and the other end of the second bronchus is connected to the bacterial powder storage box.

[0026] The beneficial effect of the basic scheme is that the second bronchus is connected to the bacterial powder storage box, the second bronchus is conducive to providing a transportation channel for the dried bacterial powder, and after the bacterial powder is dried, it slides down to the second bronchus under the action of gravity and enters the bacterial powder storage box.

[0027] Furthermore, a pressure relief valve is fixedly connected to the connection point between the first bronchus and the main air pipe, and a baffle is hingedly connected to the connection point between the second bronchus and the main air pipe. A driving component is provided on the baffle, and the driving component is connected to the controller signal.

[0028] The beneficial effects of the basic scheme are: when the driving member drives the baffle to close, the channel between the main air pipe and the second bronchial pipe is closed, which is conducive to the first air pump blowing air directly into the collection bucket through the main air pipe to dry the bacterial liquid, and the bacterial liquid will not enter the bacterial powder storage box through the second bronchial pipe. The pressure relief valve is conducive to the air flow to be ejected from the first bronchial pipe when the baffle is opened, thereby reducing the occurrence of excessive pressure in the main air pipe.

[0029] Furthermore, a temperature sensor is fixedly connected to the inner wall of the collecting bucket, and the temperature sensor is connected to the controller signal.

[0030] The beneficial effect of the basic solution is that the temperature sensor is conducive to continuous monitoring of the drying temperature in the collection bucket, which is conducive to the staff's control of the drying temperature in the collection bucket.

[0031] Furthermore, a timer is fixedly connected to the outer wall of the box body, and the timer is connected to the controller signal.

[0032] The beneficial effect of the basic solution is that the timer helps the staff to set the drying time and collect the powder at a regular time. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The conveying assembly includes a bacterial liquid conveyor 4, which is fixedly connected to one side of the top of the box body 1 by bolts, and the bacterial liquid conveyor 4 is connected to the spray assembly.

[0054] The spray assembly includes an atomizer 3 , which is fixedly connected to the top wall of the box body 1 by bolts, and the atomizer 3 is communicated with the bacterial liquid conveyor 4 .

[0055] A pressurizing assembly is provided between the atomizer 3 and the bacterial liquid conveyor 4 , and the pressurizing assembly includes a second air pump 2 . The second air pump 2 is fixedly connected to the top of the atomizer 3 by bolts, and the atomizer 3 is communicated with the second air pump 2 .

[0056] The drying component further includes a second bronchial tube 17 , which is connected to the main air pipe 15 , and the other end of the second bronchial tube 17 is connected to the bacterial powder storage box 16 .

[0057] A pressure relief valve 18 is fixedly connected to the connection point between the first bronchial pipe 13 and the main air pipe 15 by bolts, and a baffle 19 is hingedly connected to the connection point between the second bronchial pipe 17 and the main air pipe 15. A driving member is provided on the baffle 19, and the driving member is connected to the controller signal.

[0058] The inner wall of the collecting bucket 6 is fixedly connected with a temperature sensor by means of bolts, and the temperature sensor is connected with the controller signal.

[0059] The outer wall of the box body 1 is fixedly connected with a timer 5 by bolts, and the timer 5 is connected with the controller signal.

[0060] The specific implementation process is as follows: first, the controller controls the driving member to open the baffle 19, and then turns on the first air pump 14 and the resistance wire, so that the first air pump 14 blows air to the main air pipe 15 through the air outlet. Because the baffle 19 is opened, the airflow cannot pass through the baffle 19 to enter the second bronchial pipe 17 and the collecting bucket 6, so the airflow pressure in the main air pipe 15 will increase accordingly. After the pressure in the main air pipe 15 increases, it will enter the first bronchial pipe 13 through the pressure relief valve 18. The airflow entering the first bronchial pipe 13 will blow the groove to rotate the connecting block 12. The rotation of the connecting block 12 will drive the rotating column 11 to rotate. After the rotating column 11 rotates, it will drive the connecting rod 10 to rotate. Because the connecting rod 10 is fixedly connected to one end of the coil spring 20, the connecting rod 10 will rotate to provide a coil spring. The spring 20 stores energy. Because one end of the connecting rod 10 is connected to the ratchet 9, and because the eccentric wheel 8 is provided with a toothed disc that cooperates with the ratchet 9 in one direction, the ratchet 9 will not drive the eccentric wheel 8 to rotate through the toothed disc when it rotates, thereby reducing the energy loss after the coil spring 20 stores energy. After blowing for a period of time, the controller controls the driving member to drive the baffle 19 to close and block the second bronchus 17. At this time, the airflow will pass through the main air pipe 15 into the collecting bucket 6. When there is no airflow passing through the second bronchus 17, the coil spring 20 that has completed energy storage will release energy and drive the connecting rod 10 to reverse. The reversed connecting rod 10 will drive the toothed disc to rotate through the ratchet 9, thereby driving the eccentric wheel 8 to rotate. After the eccentric wheel 8 rotates, it will continuously contact the vibration rod 7, and continuously vibrate the collecting bucket 6 through the vibration rod 7.

[0061] After the collecting hopper 6 starts to vibrate, the bacterial liquid can be transported to the atomizer 3 through the bacterial liquid conveyor 4. The atomizer 3 is pressurized under the action of the second air pump 2, so that the bacterial liquid entering the atomizer 3 is dispersed into atomized small droplets under the action of pressure. Since the small droplets have a larger overall surface area, they are easier to dry under the action of the hot air blown by the first air pump 14. Since the collecting hopper 6 is constantly vibrating, the bacterial liquid attached to the inner wall of the collecting hopper 6 will continuously slide down and be dried again by the hot air.

[0062] The staff can set the heating temperature of the heating wire to 35°C and the drying time in the collecting bucket 6 to 10 minutes. The temperature sensor can monitor in real time whether the temperature information in the collecting bucket 6 is stable at 35°C±1°C. The start and stop of the heating wire controlled by the controller is conducive to the temperature stability in the collecting bucket 6. The drying time is set to 10 minutes through the timer 5. After the timing ends, the controller will control the baffle 19 to open, blocking the connection between the main air pipe 15 and the collecting bucket 6 and the second bronchus 17, and re-enabling the airflow through the first bronchus 13 to blow the connecting block 12 to rotate.

[0063] After drying is completed, only the dried Bacillus subtilis powder will remain in the collecting bucket 6. At this time, because the baffle 19 is opened, the collecting bucket 6 is connected to the second bronchial pipe 17. Under the action of gravity of the powder, the powder in the collecting bucket 6 will slide into the second bronchial pipe 17 and enter the powder storage box 16, which is convenient for subsequent staff to collect the dried powder.
