Description

Technical Field

[0001] The present invention belongs to the technical field of biological organic fertilizers, and particularly relates to a biological organic fertilizer and a preparation device thereof. Background Art

[0002] Biological organic fertilizer is a fertilizer compounded from animal and plant residues (such as livestock and poultry manure, crop straws, etc.) after harmless treatment and composting, and specific functional microorganisms (such as nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, etc.). It has the dual effects of microbial fertilizer and organic fertilizer. Compared with traditional organic fertilizers, biological organic fertilizers have faster fertilizer effects and ecological regulation functions.

[0003] However, existing biological organic fertilizers mostly use single raw materials, such as livestock and poultry manure or crop straws, with unbalanced nutrients and single fermentation strains, resulting in a long composting cycle. At the same time, when preparing biological organic fertilizers, the raw materials are not fully combined with functional microorganisms, resulting in low fertilizer effects, and thus limited effects on soil improvement and crop disease resistance enhancement.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a biological organic fertilizer and a preparation device thereof.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Invention

[0006] The purpose of the present invention is to provide a biological organic fertilizer and a preparation device thereof, which can solve the problems of single raw materials and insufficient activity of strains in existing biological organic fertilizers.

[0007] To achieve the above purpose, the technical solutions provided by a specific embodiment of the present invention are as follows:

[0008] A biological organic fertilizer, by mass fraction, includes the following components: 40 - 60 parts of livestock and poultry manure, 20 - 35 parts of crop straws, 10 - 20 parts of edible mushroom residues, 5 - 10 parts of humic acid, 3 - 8 parts of seaweed extract, 2 - 5 parts of shell powder, 1 - 3 parts of compound bacterial agent and potassium silicate nanometer.

[0009] In one or more embodiments of the present invention, the compound bacterial agent contains Bacillus subtilis, Aspergillus niger and Trichoderma viride, and the total viable count of Bacillus subtilis, Aspergillus niger and Trichoderma viride ≥ 2×10 7 CFU / g.

[0010] In one or more embodiments of the present invention, the preparation process of the biological organic fertilizer includes the following steps:

[0011] S1. Raw material pretreatment: The straw is crushed to 2 - 3 cm, and after the feces and the bacterial residue are mixed, the water content is adjusted to 50% - 60%;

[0012] S2. Primary fermentation: The pretreated raw materials are added with a compound microbial agent, and primary composting fermentation is carried out using a trough - type fermentation device. The composting temperature is 55 - 65 °C and is maintained for 5 - 7 days;

[0013] S3. Secondary fermentation: Humic acid and seaweed extract are added, and then transferred to a closed fermentation tank for secondary fermentation. The temperature is controlled at 40 - 45 °C and fermented for 10 - 15 days;

[0014] S4. Post - treatment: After the fermented product is dried, shell powder and potassium silicate nanometer are added, granulated and packaged to obtain the biological organic fertilizer.

[0015] A preparation device for biological organic fertilizer, including a turning machine installed on a trough - type fermentation device. The turning machine includes a turning machine main body, a blocking - type deodorization mechanism, several rotary spraying mechanisms and a liquid storage tank;

[0016] The blocking - type deodorization mechanism is installed on the turning machine main body. The blocking - type deodorization mechanism includes a pair of connecting seats. The pair of connecting seats are symmetrically connected to the turning machine main body. A lead screw is rotatably connected between the pair of connecting seats, and a pair of mounting plates are installed on the lead screw;

[0017] Several of the rotary spraying mechanisms are rotatably connected between the pair of mounting plates;

[0018] The liquid storage tank is installed on the turning machine main body. The liquid storage tank is provided with a deodorizing microbial agent and a liquid pumping pump. Under the action of the liquid pumping pump, the deodorizing microbial agent is sprayed out through several rotary spraying mechanisms and is in full contact with the fermented product turned by the turning machine main body to improve the deodorization effect.

[0019] In one or more embodiments of the present invention, a servo motor is installed on one of the connecting seats, and the lead screw is connected to the output end of the servo motor. When the servo motor operates, the servo motor can drive the lead screw to rotate, and then drive a pair of mounting plates and several rotary spraying mechanisms to rotate, so as to form different angles between the mounting plates and the turning machine main body to ensure the deodorization effect when the turning machine main body is in use;

[0020] A liquid distribution cavity is arranged in one of the mounting plates. The side wall of the mounting plate is connected with several connecting ends. The liquid distribution cavity is communicated with the outside through the connecting ends. A hollow sleeve is fixedly connected to the connecting end. The deodorizing microbial agent in the liquid distribution cavity can enter the hollow sleeve through the connecting end, and the hollow sleeve is used for connecting a hollow metal tube.

[0021] In one or more embodiments of the present invention, a connector is connected to the mounting plate. The connector is in communication with the liquid distribution chamber. A delivery pipe is connected between the liquid outlet end of the liquid pumping pump and the connector. When the liquid pumping pump operates, the liquid pumping pump can extract the deodorizing bacteria agent in the liquid storage tank and transport it to the liquid distribution chamber through the delivery pipe and the connector.

[0022] In one or more embodiments of the present invention, a through hole is provided on the mounting plate. The lead screw passes through the through hole. The diameter of the through hole is larger than the diameter of the lead screw. A locking bolt is threadedly connected to the mounting plate and corresponds to the lead screw. When the locking bolt does not contact the lead screw, if the lead screw rotates, the mounting plate and the rotary spraying mechanism will not rotate; if the locking bolt contacts the lead screw, when the lead screw rotates, the mounting plate and the rotary spraying mechanism will also rotate synchronously.

[0023] In one or more embodiments of the present invention, the rotary spraying mechanism includes a hollow metal tube. A plurality of liquid outlet holes are provided on the side wall of the hollow metal tube. The deodorizing bacteria agent in the hollow metal tube is discharged through the plurality of liquid outlet holes. When the fermented material passes through the gap between multiple hollow metal tubes, the deodorizing bacteria agent can fully contact the fermented material, thereby greatly improving the deodorizing effect of the fermented material;

[0024] One end of the hollow metal tube is fixedly connected with a reinforcing rod. The reinforcing rod is rotatably connected to one of the mounting plates. The end of the hollow metal tube away from the reinforcing rod is connected with a connecting metal tube. The connecting metal tube is rotatably connected to the hollow sleeve. Compared with the fixed connection method of the hollow metal tube, larger-volume fermented materials in the present application can also pass through the gap between a pair of hollow metal tubes, avoiding the blockage of a pair of hollow metal tubes by the fermented material;

[0025] The liquid distribution chamber is in communication with the inside of the hollow metal tube through the connection end, the hollow sleeve and the connecting metal tube. The deodorizing bacteria agent in the liquid distribution chamber can enter the hollow metal tube through the connection end, the hollow sleeve and the connecting metal tube, and then be discharged through the plurality of liquid outlet holes. When the turning machine main body turns the fermented material, it can fully contact the fermented material, thereby greatly improving the deodorizing effect of the fermented material. Compared with the conventional spraying deodorizing method on the market, the deodorizing bacteria agent in the present application can fully contact the fermented material, and the deodorizing effect is better and more thorough.

[0026] In one or more embodiments of the present invention, a sliding cleaning mechanism is provided between a pair of the mounting plates. When the turning machine main body does not turn the fermented material, the sliding cleaning mechanism can clean the surface of the hollow metal tube to avoid the adhesion of the fermented material;

[0027] The sliding cleaning mechanism includes a connecting sleeve which is sleeved on the lead screw. A pair of movable ear plates are symmetrically arranged inside the connecting sleeve. A screw is rotatably connected to the movable ear plate. The screw is threadedly connected to the connecting sleeve, and the movable ear plate can be threadedly connected to the lead screw. When it is necessary to make the sliding cleaning mechanism slide on the surface of the hollow metal tube, the screw is rotated to make the movable ear plate contact the lead screw. At this time, if the lead screw rotates, the screw will tend to move under the action of the thread. At the same time, since the cleaning ring is sleeved on the hollow metal tube, the cleaning ring can slide on the outer surface of the hollow metal tube, and the sliding cleaning ring is used to clean the hollow metal tube to prevent the fermentation substances from adhering to the surface of the hollow metal tube.

[0028] In one or more embodiments of the present invention, a cleaning ring is slidably arranged outside the hollow metal tube. A first connecting rod is connected between one of the cleaning rings and the connecting sleeve. A second connecting rod is connected between adjacent pairs of the cleaning rings. Multiple cleaning rings are connected into a whole with the connecting sleeve through the second connecting rod and the first connecting rod. Therefore, when the connecting sleeve is affected by the thread action, it can drive the cleaning ring to slide on the surface of the hollow metal tube for cleaning the surface of the hollow metal tube.

[0029] A pair of limiting plates are fixedly connected to the side wall of the lead screw. The connecting sleeve is arranged between the pair of limiting plates to limit the sliding distance of the connecting sleeve.

[0030] An expansion type locking mechanism is installed inside the hollow metal tube. The expansion type locking mechanism corresponds to the cleaning ring. When there is a deodorizing bactericide inside the hollow metal tube, the expansion type locking mechanism can engage with the sliding cleaning mechanism so that the sliding cleaning mechanism can be fixed and will not move when the fermentation substances are deodorized.

[0031] Compared with the prior art, a biological organic fertilizer and its preparation equipment of the present invention can effectively improve the persistence of fertilizer efficiency through the synergistic effect of multiple raw materials. By adopting the composite strain design, not only can the composting period be greatly reduced, but also the preparation effect of the biological organic fertilizer can be improved, and the use effects of the biological organic fertilizer on soil improvement and crop disease resistance can be significantly improved.

[0057] Control Example 1

[0058] The raw materials are the same as those in Example 1, and only the single strain of Bacillus subtilis is used.

[0059] Control Example 2

[0060] The raw materials are the same as those in Example 1, and nano-potassium silicate is not used.

[0061] Among them, the process parameters for preparing the biological organic fertilizer are as follows:

[0062] S1. Raw material pretreatment

[0063] Mixing stage: Use a double-shaft mixer to mix the raw materials, with a stirring speed of 30 rpm and a time of 20 minutes;

[0064] Moisture adjustment: Add clear water through an atomizing spray system to control the moisture content of the mixed material at 50%-60%;

[0065] pH adjustment: Add quicklime powder to adjust the pH value of the mixed material.

[0066] S2. First fermentation

[0067] Heap body parameters: The heap height is 1.5 m, the width is 2 m, the length is 10 m, and it is covered with a breathable film;

[0068] Ventilation and turning: Use a blower for ventilation, with a blower air volume of 0.8 m 3 / (min·m 3 ) Turn the heap body once every 12 hours;

[0069] S3. Second fermentation

[0070] First, use a screw conveyor to mix the first fermentation product, humic acid, and kelp extract;

[0071] Then transfer it to a closed fermentation tank with a volume of 10 m 3 , equipped with a PLC temperature control system, set the temperature at 42±1°C, stir 2 times a day, with a stirring speed of 15 rpm and each time for 10 minutes.

[0072] S4. Post-treatment

[0073] Drying process: Use a drum dryer for drying, and set the temperature of the drum dryer at 80°C.

[0074] Granulation parameters: A twin-screw granulator is used. The die hole diameter of the twin-screw granulator is 5 mm, the extrusion pressure is 15 MPa, and the particle strength is ≥15 N.

[0075] The bio-organic fertilizers in Examples 1 to 5 and Comparative Examples 1 to 2 were subjected to experimental tests to analyze the organic matter content, soil aggregates, and nitrogen utilization rate, and they were applied to tomato planting. The test and experimental results are as Figure 1 shown. According to Figure 1 it can be seen that the fermentation cycles of the bio-organic fertilizers in Examples 1 to 5 are significantly lower than those in Comparative Examples 1 and 2, and there are significant improvements in terms of organic matter content, soil aggregates, and nitrogen utilization. At the same time, the increase in tomato planting yield is also obvious.

[0076] As Figures 3 to 11 shown, a preparation device for a bio-organic fertilizer in an embodiment of the present invention includes a turning machine installed on a trough-type fermentation device. The turning machine includes a turning machine main body 1, a blocking deodorization mechanism 2, a plurality of rotary spraying mechanisms 3, and a liquid storage tank 4.

[0077] As Figures 3 to 11 shown, the blocking deodorization mechanism 2 is installed on the turning machine main body 1. The blocking deodorization mechanism 2 and the rotary spraying mechanism 3 cooperate with each other to form a net-like structure on the turning side of the turning machine main body 1, so that the turned fermentation material can pass through the net-like structure for deodorizing the fermentation material.

[0078] Among them, the blocking deodorization mechanism 2 includes a pair of connecting seats 201. The pair of connecting seats 201 are symmetrically connected to the turning machine main body 1, and the connecting seats 201 are used to install the mounting plate 204.

[0079] In addition, a lead screw 202 is rotatably connected between the pair of connecting seats 201. The lead screw 202 is used to drive the mounting plate 204 to rotate, and can also drive the sliding cleaning mechanism 5 to move, so as to clean the surface of the hollow metal tube 301 and prevent the fermentation material from adhering to the surface of the hollow metal tube 301.

[0080] Specifically, a pair of limiting plates 2021 are fixedly connected to the side wall of the lead screw 202, and a connecting sleeve 501 is arranged between the pair of limiting plates 2021 for limiting the sliding distance of the connecting sleeve 501.

[0081] In addition, a servo motor 203 is installed on one of the connecting seats 201, and the lead screw 202 is connected to the output end of the servo motor 203. When the servo motor 203 operates, the servo motor 203 can drive the lead screw 202 to rotate. If the locking bolt 205 contacts the lead screw 202, the lead screw 202 can drive a pair of mounting plates 204 and several rotary spraying mechanisms 3 to rotate, so as to form different angles between the mounting plate 204 and the turning machine main body 1, that is Figure 4 as shown, to ensure the deodorization effect when the turning machine main body 1 is in use.

[0082] Preferably, the servo motor 203 is a reversible motor, which can drive the lead screw 202 to rotate forward and backward, and further can control the sliding cleaning mechanism 5 to slide back and forth on the surface of the hollow metal tube 301 to achieve reciprocating cleaning of the surface of the hollow metal tube 301.

[0083] As Figures 3 to 11 shown, a pair of mounting plates 204 are installed on the lead screw 202. The mounting plates 204 are used to install a plurality of rotary spraying mechanisms 3, and at the same time, are used to convey deodorizing bacteria agents to the rotary spraying mechanisms 3.

[0084] A liquid distribution cavity 2041 is arranged in one of the mounting plates 204. A plurality of connection ends 2042 are connected to the side wall of the mounting plate 204. The liquid distribution cavity 2041 is communicated with the outside through the connection ends 2042, and a hollow sleeve 2043 is fixedly connected to the connection ends 2042. The deodorizing bacteria agent in the liquid distribution cavity 2041 can enter the hollow sleeve 2043 through the connection ends 2042. The hollow sleeve 2043 is used to connect the hollow metal tube 301.

[0085] In addition, the liquid distribution cavity 2041 is communicated with the inside of the hollow metal tube 301 through the connection ends 2042, the hollow sleeve 2043 and the connecting metal tube 303. The deodorizing bacteria agent in the liquid distribution cavity 2041 can enter the hollow metal tube 301 through the connection ends 2042, the hollow sleeve 2043 and the connecting metal tube 303, and then be discharged through a plurality of liquid outlet holes. When the turning machine main body 1 turns over the fermented material, it can be in full contact with the fermented material, and thus the deodorization effect of the fermented material can be greatly improved. Compared with the conventional spraying deodorization method on the market, the deodorizing bacteria agent in this application can be in full contact with the fermented material, and the deodorization effect is better and more thorough.

[0086] Specifically, a connection head 2044 is connected to the mounting plate 204, and the connection head 2044 is communicated with the liquid distribution cavity 2041. A delivery pipe 401 is connected between the liquid outlet end of the liquid extraction pump and the connection head 2044. When the liquid extraction pump operates, the liquid extraction pump can extract the deodorizing bacteria agent in the liquid storage tank 4 and convey it to the liquid distribution cavity 2041 through the delivery pipe 401 and the connection head 2044.

[0087] In addition, through holes are provided on the mounting plate 204, and the lead screw 202 passes through the through holes. The diameter of the through holes is larger than that of the lead screw 202. A locking bolt 205 is threadedly connected to the mounting plate 204, and the locking bolt 205 corresponds to the lead screw 202. When the locking bolt 205 does not contact the lead screw 202, if the lead screw 202 rotates, the mounting plate 204 and the rotary spraying mechanism 3 will not rotate. If the locking bolt 205 contacts the lead screw 202, then when the lead screw 202 rotates, the mounting plate 204 and the rotary spraying mechanism 3 will also rotate synchronously, for adjusting the inclination angle of the blocking deodorization mechanism 2 so as to deodorize the fermented material.

[0088] As Figures 3 to 11 shown, a plurality of rotary spraying mechanisms 3 are rotatably connected between a pair of mounting plates 204. The rotary spraying mechanisms 3 and the mounting plates 204 form a net structure. Coupled with the function of spraying the deodorizing bacteria agent by the rotary spraying mechanisms 3, the deodorization effect of the turned-over fermented material can be greatly improved. Compared with the traditional way of spraying on the upper side of the fermented material, the deodorizing bacteria agent in this application can fully contact the fermented material, thereby greatly improving the deodorization effect of the fermented material and also improving the turning-over effect.

[0089] Among them, the rotary spraying mechanism 3 includes a hollow metal tube 301, and a plurality of liquid outlet holes are provided on the side wall of the hollow metal tube 301. The deodorizing bacteria agent in the hollow metal tube 301 is discharged through the plurality of liquid outlet holes. When the fermented material passes through the gaps between the plurality of hollow metal tubes 301, the deodorizing bacteria agent can fully contact the fermented material, thereby greatly improving the deodorization effect of the fermented material.

[0090] In addition, one end of the hollow metal tube 301 is fixedly connected with a reinforcing rod 302. The reinforcing rod 302 is rotatably connected to one of the mounting plates 204. The end of the hollow metal tube 301 far from the reinforcing rod 302 is connected with a connecting metal tube 303, and the connecting metal tube 303 is rotatably connected to the hollow sleeve 2043. Compared with the fixed connection method of the hollow metal tube 301, fermented materials with a larger volume can also pass through the gaps between a pair of hollow metal tubes 301, avoiding the blockage of a pair of hollow metal tubes 301 by the fermented materials.

[0091] As Figures 3 to 11 shown, the liquid storage tank 4 is installed on the turning machine main body 1. The liquid storage tank 4 is provided with a deodorizing bacteria agent and a liquid extraction pump. The deodorizing bacteria agent is sprayed out through a plurality of rotary spraying mechanisms 3 under the action of the liquid extraction pump and fully contacts the fermented material turned over by the turning machine main body 1 for improving the deodorization effect.

[0092] Among them, an observation plate and an adding pipe are further provided on the side wall of the liquid storage tank 4. The capacity of the deodorizing bacteria agent can be observed through the observation plate, and the deodorizing bacteria agent can be supplemented into the liquid storage tank 4 through the adding pipe.

[0093] In addition, a fresh water storage cavity is also provided in the liquid storage tank 4. A liquid extraction pump is also provided in the fresh water storage cavity. A branch pipe is connected between the output end of the liquid extraction pump and the delivery pipe 401, and a control valve is installed on the branch pipe.

[0094] When it is necessary to clean the surface of the hollow metal tube 301, the liquid extraction pump in the fresh water storage cavity operates, and thus fresh water can be extracted. Then, it enters the hollow metal tube 301 through the delivery pipe 401, the connector 2044, the liquid distribution cavity 2041, the connection end 2042, the hollow sleeve 2043 and the connecting metal tube 303, and is discharged through the liquid outlet holes. With the reciprocating sliding cleaning of the cleaning ring 504, a better cleaning effect can be achieved on the hollow metal tube 301.

[0095] As Figures 3 to 11 shown, a sliding cleaning mechanism 5 is provided between a pair of mounting plates 204. When the main body 1 of the turning machine does not turn the fermented material, the sliding cleaning mechanism 5 can clean the surface of the hollow metal tube 301 to avoid the adhesion of the fermented material.

[0096] Among them, the sliding cleaning mechanism 5 includes a connecting sleeve 501. The connecting sleeve 501 is sleeved on the lead screw 202. A pair of movable ear plates 502 are symmetrically arranged in the connecting sleeve 501. A screw 503 is rotatably connected to the movable ear plate 502. The screw 503 is threadedly connected to the connecting sleeve 501, and the movable ear plate 502 can be threadedly connected to the lead screw 202.

[0097] When it is necessary to make the sliding cleaning mechanism 5 slide on the surface of the hollow metal tube 301, the screw 503 is rotated so that the movable ear plate 502 contacts the lead screw 202. At this time, if the lead screw 202 rotates, the screw 503 will tend to move under the action of the thread. Since the cleaning ring 504 is sleeved on the hollow metal tube 301, the cleaning ring 504 can be made to slide on the outer surface of the hollow metal tube 301, and the sliding cleaning ring 504 is used to clean the hollow metal tube 301 to avoid the adhesion of the fermented material on the surface of the hollow metal tube 301.

[0098] In addition, a cleaning ring 504 is slidably arranged outside the hollow metal tube 301. A first connecting rod 505 is connected between one of the cleaning rings 504 and the connecting sleeve 501, and a second connecting rod 506 is connected between adjacent pairs of cleaning rings 504. A plurality of cleaning rings 504 are connected to the connecting sleeve 501 into a whole through the second connecting rod 506 and the first connecting rod 505. Thus, when the connecting sleeve 501 is affected by the thread, it can drive the cleaning ring 504 to slide on the surface of the hollow metal tube 301 for cleaning the surface of the hollow metal tube 301.

[0099] As Figures 3 to 11As shown in the figure, an expansion type locking mechanism 6 is installed inside the hollow metal tube 301, and the expansion type locking mechanism 6 corresponds to the cleaning ring 504. When the hollow metal tube 301 sprays deodorant bacteria agent, the expansion type locking mechanism 6 can engage and slide the cleaning mechanism 5, so that when deodorizing the fermented matter, the sliding cleaning mechanism 5 can be fixed and will not move.

[0100] Among them, the expansion type locking mechanism 6 includes a collecting member 601. The collecting member 601 is arranged inside the hollow metal tube 301, and a hollow groove 602 is arranged inside the collecting member 601. When there is deodorant bacteria agent in the hollow metal tube 301, the deodorant bacteria agent will also enter the hollow groove 602 and squeeze the stress plate 605 through the sliding groove.

[0101] In addition, a pair of locking columns 603 are symmetrically arranged inside the collecting member 601. One end of the locking column 603 passes through the side wall of the hollow metal tube 301, and a clamping bead 604 is installed at the end of the locking column 603. A clamping ring 5041 matching the clamping bead 604 is arranged inside the cleaning ring 504. When the clamping bead 604 is clamped into the clamping ring 5041, the clamping and fixing of the sliding cleaning mechanism 5 can be realized, so that when the hollow metal tube 301 sprays deodorant bacteria agent, the sliding cleaning mechanism 5 will not move, ensuring the spraying effect of the deodorant bacteria agent.

[0102] Preferably, the clamping ring 5041 is an annular groove, which will not affect the rotary spraying of the hollow metal tube 301.

[0103] Specifically, the other end of the locking column 603 is connected with a stress plate 605. A sliding groove matching the stress plate 605 is arranged inside the collecting member 601, and the sliding groove is communicated with the hollow groove 602. When the deodorant bacteria agent is sprayed through the liquid outlet hole on the hollow metal tube 301, the deodorant bacteria agent will also squeeze the stress plate 605 through the hollow groove 602 and the sliding groove. When the extrusion force of the deodorant bacteria agent on the stress plate 605 is greater than the elastic force of the elastic rope 606, the locking column 603 will be extruded, so that the clamping bead 604 can enter the clamping ring 5041. At this time, the clamping and fixing of the sliding cleaning mechanism 5 can be realized.

[0104] In addition, an elastic rope 606 is connected between the pair of stress plates 605. The elastic rope 606 passes through the hollow groove 602. When the stress plate 605 is not squeezed by the deodorant bacteria agent, the locking column 603 and the clamping bead 604 will retract into the hollow metal tube 301 under the action of the elastic rope 606, and then the sliding cleaning mechanism 5 can be released, so that the sliding cleaning mechanism 5 can slide on the surface of the hollow metal tube 301 for cleaning.

[0105] During specific use, when it is necessary to turn over the fermented material in the tank-type fermentation equipment using the turning machine main body 1, first turn a pair of locking bolts 205 so that the locking bolts 205 contact the lead screw 202, and then control the operation of the servo motor 203. The servo motor 203 drives the lead screw 202 to rotate. The rotating lead screw 202 drives a pair of mounting plates 204 to rotate through the locking bolts 205. The mounting plates 204 drive a number of rotary spraying mechanisms 3 to rotate, so that a certain angle is formed between the mounting plates 204 and the turning machine main body 1. Stop the operation of the servo motor 203, that is Figure 4 the state shown.

[0106] Operate the turning machine main body 1 so that the turning machine main body 1 turns over the fermented material in the tank-type fermentation equipment. A pair of mounting plates 204 and a number of rotary spraying mechanisms 3 can form a mesh structure on the turning side of the turning machine main body 1, and the fermented material can be better turned over by using the mesh structure.

[0107] In addition, when turning over the fermented material, operate the liquid extraction pump storing the deodorizing bactericide in the liquid storage tank 4. The deodorizing bactericide is transported to the liquid distribution cavity 2041 through the delivery pipe 401 and the connector 2044 under the action of the liquid extraction pump. Then, it enters a number of hollow metal pipes 301 through a number of connection ends 2042, hollow sleeves 2043 and connection metal pipes 303 respectively. Finally, it is discharged through the liquid outlet holes on the hollow metal pipes 301 to achieve a mesh-type spraying effect.

[0108] Since the fermented material will pass through the mesh structure, when the turned-over fermented material passes through the gap between a pair of hollow metal pipes 301, the deodorizing bactericide can be in full contact with the fermented material, thereby greatly improving the deodorizing effect of the fermentation bactericide. At the same time, since the hollow metal pipes 301 can rotate, if a relatively large fermented material passes through the gap between a pair of hollow metal pipes 301, the rotatability of the hollow metal pipes 301 can be used to effectively avoid the blockage and accumulation of the fermented material and ensure the turning-over and deodorizing effects of the fermented material.

[0109] When the deodorizing bactericide is sprayed through the liquid outlet holes on the hollow metal pipes 301, the deodorizing bactericide will also squeeze the stress plate 605 through the hollow groove 602 and the sliding groove. When the extrusion force of the deodorizing bactericide on the stress plate 605 is greater than the elastic force of the elastic rope 606 on the stress plate 605, the locking column 603 will be extruded and move out of the side wall of the hollow metal pipe 301, so that the engaging bead 604 can enter the engaging ring 5041. At this time, the engaging and fixing of the sliding cleaning mechanism 5 can be realized, and the sliding cleaning mechanism 5 can be prevented from moving arbitrarily when the hollow metal pipes 301 spray the deodorizing bactericide.

[0110] After the turning-over of the fermented material is completed, first control the rotation of the servo motor 203 so that the mounting plate 204 rotates into Figure 3The state shown, i.e., the mounting plate 204 is in a vertical state. Loosen the locking bolt 205 so that the locking bolt 205 disengages from contact with the lead screw 202. Then rotate the screw 503, and the screw 503 drives the movable ear plate 502 to move, and makes a pair of movable ear plates 502 contact with the lead screw 202. Control the operation of the servo motor 203, and the lead screw 202 rotates again. Due to the threaded action, the screw 503 has a tendency to move. Since there is no liquid flowing in the hollow metal tube 301, at this time, the engaging bead 604 is received in the hollow metal tube 301, and thus the cleaning ring 504 can slide on the outer surface of the hollow metal tube 301, and the sliding cleaning ring 504 is used to clean the hollow metal tube 301 to prevent the fermentation substances from adhering to the surface of the hollow metal tube 301.

[0111] When the cleaning ring 504 slides to clean the surface of the hollow metal tube 301, operate the liquid extraction pump in the fresh water storage chamber. The liquid extraction pump extracts fresh water, and conveys the fresh water into the hollow metal tube 301 through the delivery pipe 401, the connector 2044, the liquid distribution cavity 2041, the connection end 2042, the hollow sleeve 2043 and the connecting metal tube 303 and discharges it through the liquid outlet hole. Then, with the reciprocating sliding cleaning of the cleaning ring 504, a better cleaning effect on the hollow metal tube 301 can be achieved.

[0112] In addition, the fresh water flowing in the hollow metal tube 301 will make the engaging bead 604 protrude from the side wall of the hollow metal tube 301 again. With the cooperation of the limiting plate 2021, the moving distance of the sliding cleaning mechanism 5 can be limited to prevent the sliding cleaning mechanism 5 from being damaged by impact.
