[0023] Beneficial Effects

[0024] The present invention provides a microbial fermentation device and a fermentation method for producing biological organic fertilizer. Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. A microbial fermentation device and fermentation method for producing biological organic fertilizer. Through the cooperation between the leading-out cutting mechanism, the servo motor and the forming disk switching mechanism, the organic materials are decomposed in the microbial fermentation process. After the organic materials are converted into biological organic fertilizer, the valve is opened to allow the organic fertilizer in the fermentation tank mechanism to enter the leading-out cutting mechanism through the feeding pipe. The leading-out cutting mechanism pushes the organic fertilizer forward, and finally guides the organic fertilizer to the outside through the forming disk switching mechanism. Under the action of the forming disk switching mechanism, the organic fertilizer can be discharged in a shape with a set outer diameter. Since the leading-out cutting mechanism is adjusted in advance, the leading-out cutting mechanism is set to be intermittent for a set time, so that the organic fertilizer led out from the front of the forming disk switching mechanism is automatically cut, and the discharged organic fertilizer is cut into a set length. According to production requirements, the organic fertilizer can be cut into a plurality of granules with a set size in a timely and automatic manner and then discharged, thereby reducing subsequent mechanical processing operations, reducing production costs, and facilitating subsequent use and storage.

[0026] 2. A microbial fermentation device and fermentation method for producing biological organic fertilizer. Through the mutual cooperation between the spiral blade, the friction cylinder assembly, the cutting rod assembly, the adjusting rod assembly and the forming disk, the rotating shaft and the spiral blade are rotated under the drive of the servo motor to push the organic fertilizer in the outlet pipe forward. At the same time, under the action of the first gear, the toothed belt and the second gear, the conical friction cylinder can be driven to rotate. Since the side wall of the conical friction cylinder is in contact with the side wall of the friction disk, the friction force can be used to drive the cutting rod assembly to rotate during the rotation of the conical friction cylinder. The blade in the cutting rod assembly passes in front of the rightmost forming disk during the rotation process, so that the blade can be used to automatically cut the organic fertilizer discharged from the rightmost forming disk intermittently. The operation is relatively convenient, and there is no need to add an additional power mechanism to drive the blade to rotate for the cutting operation, thereby reducing the cost of the device.

[0027] 3. A microbial fermentation device and fermentation method for bio-organic fertilizer production, through the mutual cooperation among the conical friction cylinder, friction disk, threaded rod, internal threaded sleeve, adjusting shaft assembly and positioning assembly, the arc tooth plate is pulled forward to release the lock of the adjusting shaft assembly, and then the adjusting shaft is rotated to drive the threaded rod to rotate, and under the limiting action of the collar, the internal threaded sleeve is moved in the front and rear directions along the threaded rod, and at the same time, the collar drives the friction disk to move in the front and rear directions along the second shaft rod. During the process, the side wall of the friction disk is always in contact with the side wall of the conical friction cylinder. After the friction disk is adjusted to the specified position, the pull on the push-pull block is released. Under the elastic action of the spring, the arc tooth plate returns to its original position, and the position of the adjusting shaft assembly is locked, that is, the positions of the internal threaded sleeve and the friction disk are limited, so as to realize the cutting of the blade. The frequency of cutting organic fertilizer is adjusted. During the process, since the conical friction cylinder is in the shape of a cone, when the friction disk is gradually adjusted toward the end of the conical friction cylinder with a larger outer diameter, the conical friction cylinder rotates one circle under the condition that the speed of the first shaft remains unchanged, and the friction disk can be driven to rotate several circles, so as to achieve the purpose of accelerating the speed of the friction disk, and then accelerate the frequency of the blade cutting the organic fertilizer, so as to achieve the purpose of reducing the length of the organic fertilizer particles cut. Conversely, when the friction disk is gradually adjusted toward the end of the conical friction cylinder with a smaller outer diameter, the speed of the first shaft remains unchanged, and the rotation speed of the friction disk gradually decreases, so as to achieve the purpose of slowing down the speed of the friction disk, and then slowing down the frequency of the blade cutting the organic fertilizer, so as to achieve the purpose of increasing the length of the organic fertilizer particles cut. The discharged organic fertilizer can be cut into a set length as needed, with strong flexibility and a wide range of applications.

[0028] 4. A microbial fermentation device and fermentation method for producing biological organic fertilizer. Through the mutual cooperation between the semicircular cover, the bearing shaft, the placement ring and the forming disk, the forming disk containing the required forming holes can be quickly switched to the rightmost part so that it is located in front of the outlet pipe and behind the blade. The squeezed organic fertilizer is discharged through the various forming holes in the forming disk. Under the action of the forming holes, it can extrude a shape that matches the inner diameter of the forming hole. The setting of the first bolt can remove the forming disk in the placement ring and flexibly replace it with a forming disk containing the required forming holes. BRIEF DESCRIPTION OF THE DRAWINGS

There is no need to add an additional power mechanism to drive the blade 587 to rotate for cutting operation, which reduces the cost of the device. Through the cooperation between the conical friction cylinder 572, the friction disk 584, the threaded rod 591, the internal threaded sleeve 592, the adjustment shaft assembly 597 and the positioning assembly 598, the arc tooth plate 5983 is pulled forward to release the lock of the adjustment shaft assembly 597, and then the adjustment shaft 5971 is rotated to drive the threaded rod 591 to rotate. Under the limiting action of the collar 593, the internal threaded sleeve 592 moves along the threaded rod 591 in the front-to-back direction. At the same time, the collar 593 drives the friction disk 584 to move along the second shaft rod 581 in the front-to-back direction. During the friction process The side wall of the disk 584 is always in contact with the side wall of the conical friction cylinder 572. After the friction disk 584 is adjusted to the specified position, the pull on the push-pull block 5982 is released. Under the elastic action of the spring 5985, the arc-shaped tooth plate 5983 returns to its original position, and the position of the adjustment shaft assembly 597 is locked, that is, the position of the internal threaded sleeve 592 and the friction disk 584 is limited, so that the frequency of cutting organic fertilizer by the blade 587 is adjusted. During the process, since the conical friction cylinder 572 is in the shape of a cone, when the friction disk 584 is gradually adjusted toward the end with a larger outer diameter of the conical friction cylinder 572, when the rotation speed of the first shaft rod 571 remains unchanged, the conical friction cylinder 572 rotates one circle, which can drive the friction disk 584 to rotate several circles, so as to accelerate the rotation speed of the friction disk 584 The purpose of this invention is to speed up the frequency of cutting the organic fertilizer by the blade 587, so as to reduce the length of the organic fertilizer particles cut. On the contrary, when the friction disk 584 is gradually adjusted to the end with the smaller outer diameter of the conical friction cylinder 572, the rotation speed of the friction disk 584 gradually decreases when the rotation speed of the first shaft 571 remains unchanged, so as to achieve the purpose of slowing down the rotation speed of the friction disk 584, and then slow down the frequency of cutting the organic fertilizer by the blade 587, so as to increase the length of the organic fertilizer particles cut. The discharged organic fertilizer can be cut into a set length as needed, with strong flexibility and a wide range of applications. Through the mutual cooperation among the semicircular cover 71, the bearing shaft 72, the placement ring 73 and the forming disk 75, the forming disk 75 containing the required forming holes can be quickly switched to the rightmost part.It is located in front of the outlet pipe 51 and behind the blade 587. The squeezed organic fertilizer is discharged through the various forming holes in the forming disk 75. Under the action of the forming holes, it can be extruded into a shape that matches the inner diameter of the forming hole. The first bolt 74 is set to remove the forming disk 75 in the placement ring 73 and flexibly replace it with a forming disk 75 containing the required forming holes.

[0058] Step 1, organic material and microorganism are put into the fermentation tank mechanism 1 through the feed end 2, wherein the fermentation tank mechanism 1 belongs to the prior art well known to those skilled in the art, the fermentation tank mechanism 1 is mainly composed of a tank body, a stirring system, a temperature control system, an oxygen supply system, a monitoring and control system, an auxiliary drying system, a conveying auger and a motor, the motor on the fermentation tank mechanism 1 is turned on, the stirring system in the tank body is driven by the motor, the raw materials in the tank body are stirred, and the temperature and oxygen in the tank body are adjusted to the required values ​​by the temperature control system and the oxygen supply system at the same time, the organic material and the microorganism in the tank body are regularly stirred by the stirring system, the organic material and the microorganism are uniformly mixed, and oxygen is regularly introduced into the tank body by the oxygen supply system, so that the microorganism is fully in contact with oxygen, and necessary oxygen environment is provided for the reproduction and metabolism of the microorganism, the microorganism rapidly reproduces and decomposes the organic material under suitable temperature and oxygen conditions, and finally the organic material is converted into biological organic fertilizer, and after the fermentation is completed, the organic fertilizer is dried by the auxiliary drying system;

[0059] Step 2, then open the valve, use the conveying auger to push the solid organic fertilizer in the tank body toward the lower feeding pipe 4, so that the solid organic fertilizer in the fermentation tank mechanism 1 falls into the outlet pipe 51 through the lower feeding pipe 4, and under the drive of the servo motor 6, the rotating shaft 54 ​​and the spiral blade 55 are rotated to push the organic fertilizer in the outlet pipe 51 forward, and the squeezed organic fertilizer is discharged through each forming hole in the rightmost forming disk 75, and under the action of the forming hole, the organic fertilizer is squeezed into a shape that matches the inner diameter of the forming hole;

[0060] Step 3, under the action of the first gear 56, the toothed belt 510 and the second gear 573, the rotating shaft 54 ​​rotates and drives the conical friction cylinder 572 to rotate. Since the side wall of the conical friction cylinder 572 is in contact with the side wall of the friction disk 584, the friction disk 584 can be driven to rotate by the friction force during the rotation of the conical friction cylinder 572, that is, the cutting rod assembly 58 is driven to rotate. The blade 587 in the cutting rod assembly 58 passes in front of the rightmost forming disk 75 during the rotation, so that the blade 587 intermittently cuts the organic fertilizer discharged from the forming hole, and finally the organic fertilizer is cut into a plurality of particles of a set size and then discharged.
