In addition, excessive reliance on chemical fertilizers may also reduce the quality of agricultural products and affect human health. Therefore, the development of new green, environmentally friendly and efficient fertilizers has become an inevitable trend in the development of modern agriculture.

[0003] As a type of sustainable fertilizer, bio-organic fertilizer has attracted much attention because of its ability to provide rich organic matter, improve soil physical properties, and activate beneficial microbial communities in the soil.

However, most bio-organic fertilizers on the market currently have the following shortcomings: Single nutritional ingredients: Many products contain only a small amount of fixed microorganisms or a limited variety of organic materials, which are difficult to meet the diverse needs of different crops throughout the growth cycle. When the existing granulator extrudes and granulates the material, the fertilizer is directly transported to the shear end through the spiral impeller, the extrusion effect is poor, and the pressure is uneven. The quality of the finished product is unstable, and a good granulation effect cannot be formed, which has an adverse effect on the molding of organic fertilizers.

[0026] The present invention has the following beneficial effects: 1. The present invention is a granular biological organic fertilizer, which uses soybean meal and monosodium glutamate waste as basic organic matter. Soybean meal (soybean meal) is the solid part remaining after soybean oil is extracted. It is rich in protein, amino acids and trace elements and is a high-quality organic material. Soybean meal is rich in nitrogen, phosphorus, potassium and other essential nutrients for plants, especially high nitrogen content, which helps to improve soil fertility. It also contains a variety of trace nutrients such as calcium, magnesium, iron, zinc, etc. Due to its fiber content, soybean meal can increase the organic matter in the soil, help improve the soil structure, enhance the soil air permeability and water retention capacity, and long-term application can enhance the soil aggregate structure and promote root development. Soybean meal is also a good food source for microorganisms, which can quickly activate the beneficial microbial community in the soil, accelerate the decomposition of organic matter, and form humus. MSG waste, which is the byproduct or waste in the production process of monosodium glutamate, contains a certain amount of nitrogen, which can provide necessary nutrients for plants. By adding MSG waste, the level of organic matter in the soil can be significantly increased, thereby improving the soil structure, enhancing the aeration and water retention capacity of the soil; it can promote the development of beneficial microbial communities, accelerate the decomposition of organic matter, and form humus. These microorganisms can also fix nitrogen in the air and further enrich soil nutrients. Using soybean meal and MSG waste as biological organic fertilizer not only helps to recycle resources and reduce the impact of industrial waste on the environment, but also realizes the reuse value of waste.

The biological organic fertilizer of the present invention is compounded with four kinds of Bacillus, which can promote plant growth, improve soil structure, secrete polysaccharides and extracellular polymers: these substances help stabilize soil particles, improve soil aggregate structure, increase air permeability and water retention capacity, and are conducive to root expansion. Promote the decomposition of organic matter: Bacillus can accelerate the degradation of organic materials, convert complex organic compounds into simple small molecules, which are convenient for plants to absorb and utilize, and provide carbon sources and energy for other microorganisms. It can also enhance crop disease resistance, improve fertilizer utilization, reduce the use of chemical pesticides, and promote sustainable development.

[0072] The extrusion discharge part 400 includes: a compression box 401 with an open top, a granulation disk 402, a pressure block 403, a longitudinal axis 404, a pressure spring body 405 and a retaining ring 406; the compression inlet of the compression box 401 is connected to the transfer outlet of the transfer cylinder 302, and the compression outlet of the compression box 401 is connected to the granulation disk 402 with a granulation hole. The pressure block 403 is slidably connected inside the compression box 401, and one side of the pressure block 403 is blocked on the inner side of the compression outlet. The lower surface of the pressure block 403 is an inclined pressure surface inclined from one end close to the compression inlet to one end of the compression outlet. The pressure block 403 is connected to the bottom of more than one longitudinal axis 404, and the middle part of the longitudinal axis 404 is slidably connected to the support frame plate on the top of the compression box 401. The retaining ring 406 threadedly connected above the longitudinal axis 404 is clamped above the support frame plate, and the pressure spring body 405 sleeved on the longitudinal axis 404 is located between the pressure block 403 and the support frame plate. The compression inlet of the compression box 401 is connected with the transfer outlet of the transfer cylinder 302. After the fertilizer raw materials in the transfer cylinder 302 enter the compression box 401 under the action of the spiral auger 303, pressure can be generated on the inclined pressure surface of the lower surface of the pressing block 403. With the continuous input of the fertilizer raw materials, the fertilizer raw materials are effectively squeezed. When the squeezing force reaches a preset value, the pressing block 403 is gradually pushed to move upward. While the pressing block 403 moves upward to compress the pressure-bearing spring body 405, the pressing block 403 gradually releases the blockage of the compression outlet, so that the fertilizer raw materials can be squeezed out through the granulation holes of the granulation disk 402 at the compression outlet, and cut into fertilizer particles by the cutting part 500, thereby realizing the granulation of the fertilizer. By setting the pressure-bearing spring body 405 and the pressing block 403, the quality stability of the subsequent fertilizer granulation products is guaranteed, and the fertilizer particles are prevented from being loose and fragile.

[0073] A variable pressure counterweight port for adding counterweight is provided on the top of the pressure block 403. A transverse reinforcement frame fixed in the variable pressure counterweight port is connected to the lower end of the longitudinal axis 404. The pressure spring body 405 is located between the transverse reinforcement frame and the support frame plate. The compression effect can be changed by adding counterweights to the variable pressure counterweight port, such as adding water. The operation is very convenient, so that the pressure of the fertilizer raw material can be adjusted to meet the granulation requirements of different fertilizer raw materials.

[0074] The cutting part 500 includes: a cutting motor and a cutting blade; the cutting motor is installed on the compression box 401 through the motor seat 304, and the multiple cutting blades fixed on the output shaft of the cutting motor are slidably matched on the outer surface of the granulating disk 402. After the cutting motor is started, it can drive the multiple cutting blades on the output shaft of the cutting motor to cut the fertilizer extruded from the granulating hole of the granulating disk 402 to form fertilizer particles.

[0075] The transfer cylinder 302 is slidably connected to the compression inlet of the compression box 401. One end of the transfer cylinder 302 inserted into the compression box 401 is provided with a top pressure ring 305, which is slidably fitted on the inclined pressure surface below the compression block 403. The transfer cylinder 302 is fixedly connected with an electric push rod 306, and the movable end of the electric push rod 306 is connected to the compression box 401. The compression box 401 can be controlled to slide on the transfer cylinder 302 by the electric push rod 306, and the length of the transfer cylinder 302 inserted into the compression box 401 can be changed. When the length of the transfer cylinder 302 inserted into the compression box 401 increases, the inclined pressure surface below the compression block 403 can be pressed, so that the compression block 403 moves upward, and the blockage of the granulation disk 402 at the compression outlet is released, which can meet more usage conditions.
