[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0034] See also Figure 1-10A liquid organic fertilizer preparation and fermentation device provided by an embodiment of the present invention includes a kettle body 1 and a stirring shaft 2, which is arranged inside the kettle body 1. A guide ring 101 and a guide ring 102 distributed up and down are fixedly connected in the kettle body 1. The stirring shaft 2 is equipped with a guide plate 201 below the guide ring 101. A stirring and grinding component 3 is annularly distributed on the guide plate 201. The top of the stirring and grinding component 3 is plugged into the guide ring 101. A plurality of material troughs 103 are provided in the guide ring 102. One side of the stirring and grinding component 3 is in contact with the material trough 103. When the stirring shaft 2 drives the guide plate 201 to rotate, each stirring and grinding component 3 moves back and forth under the guidance of the guide ring 101 and enters and exits each material trough 103 synchronously.

[0035] Specifically, the kettle body 1 is cylindrical, with a sealing cover at the top feed inlet, and a discharge port and a corresponding valve control device at the bottom to facilitate the discharge of organic fertilizer after fermentation is completed. At the same time, the stirring shaft 2 is vertically arranged in the center of the kettle body 1, and the stirring shaft 2 is connected to the driving motor 204 installed on the top of the kettle body 1. The stirring shaft 2 is driven to rotate in the kettle body 1 by the driving motor 204. The guide ring 101 and the guide ring 102 are respectively fixedly connected to the upper and lower areas of the kettle body 1. The guide ring 101 is used to guide each stirring and grinding component 3 that rotates with the stirring shaft 2 as the axis, so that the stirring and grinding component 3 can move radially back and forth on the guide plate 201 , the guide ring 102 is located below the guide plate 201, and the organic fertilizer material falling from the guide plate 201 will fall into the troughs 103 opened on the guide ring 102. These troughs 103 not only promote the circulation of materials, but also provide access channels for the stirring and grinding component 3. When the stirring and grinding component 3 enters the trough 103, it will crush and crush the materials temporarily stored in the trough 103, so that the materials discharged from the trough 103 are looser and prevent the materials from agglomerating and accumulating. When the driving motor 204 is started, the stirring shaft 2 drives the guide plate 201 to rotate. At the same time, through the guiding effect of the guide ring 101, the stirring and grinding component 3 moves back and forth up and down along its guide groove. In this process, the grinding head of the stirring and grinding component 3 continuously enters and exits the trough 103 of the guide ring 102, which not only realizes the up and down flipping and radial mixing of the materials, but also further refines the material particles through the crushing effect of the grinding head, promotes the full contact between microorganisms and organic matter, and accelerates the fermentation process.

[0036] Compared with the prior art, the embodiment of the present invention guides the falling direction of the raw materials through the guide ring 101 and the guide ring 102 structure arranged in the kettle body 1, and cooperates with the guide plate 201 on the stirring shaft 2 and the annularly distributed stirring and grinding components 3 to achieve uniform mixing and efficient fermentation of the liquid organic fertilizer material in the kettle body 1. When the stirring shaft 2 drives the stirring and grinding components 3 on the guide plate 201 to rotate, the stirring and grinding components 3 will reciprocate under the guidance of the guide ring 101, and synchronously enter and exit the material trough 103 of the guide ring 102, which not only enhances the stirring and mixing effect, but also promotes the full grinding and reaction of the fertilizer, ensuring that the organic fertilizer can be fully fermented in the reactor.

[0037] In a further embodiment of the present invention, a support ring 4 is fixedly connected to the kettle body 1, and a centrifugal screen ring 401 is elastically rotatably installed on the top of the support ring 4, and a torsion spring (not shown in the figure) is installed between the centrifugal screen ring 401 and the support ring 4, and the centrifugal screen ring 401 is located between the guide plate 201 and the support ring 4, and a plurality of push rods 402 are fixedly connected to the bottom of the centrifugal screen ring 401, and the number of the push rods 402 corresponds to the stirring and grinding assembly 3, and an arc groove for the push rod 402 to move is opened on the support ring 4, and the stirring and grinding assembly 3 is in abutment with the push rod 402 passing through the arc groove. Specifically, the push rod 402 at the bottom of the centrifugal screen ring 401 moves with the rotation of the centrifugal screen ring 401. When each stirring and grinding assembly 3 moves back and forth in the radial direction and rotates around the stirring shaft 2 During the movement, it will come into contact with the push rods 402 at the bottom of the centrifugal sieve ring 401. When the stirring and grinding component 3 encounters the push rods 402, if the push rods 402 block the outward-moving stirring and grinding component 3, the stirring and grinding component 3 will push the push rods 402 in the overall rotation direction to drive the centrifugal sieve ring 401 to rotate, until the stirring and grinding component 3 moves inward and away from the push rods 402 under the guidance of the guide ring 101. At this time, the centrifugal sieve ring 401 is quickly reset under the action of the torsion spring, so that the reciprocating rotation of the centrifugal sieve ring 401 can realize rapid screening and falling of the material, thereby preventing the agglomerated material from entering the material trough 103, and the reciprocating rotation of the centrifugal sieve ring can be used to throw out the material falling on its surface, so that the material continues to fall after contacting the inner wall of the reactor.

[0038] In a further embodiment of the present invention, the guide ring 101 includes an outer ring 104 fixed to the inner wall of the kettle body 1, an inner ring 105 is clamped inside the outer ring 104, a circle of guide channel 106 for the stirring and grinding component 3 to move is formed between the outer ring 104 and the inner ring 105, a plurality of clamping blocks are distributed in an annular manner on the top of the inner ring 105, and a clamping groove for inserting the clamping blocks is opened on the top of the outer ring 104. Specifically, the guide ring 101 is composed of two parts, the outer ring 104 and the inner ring 105 clamped in the outer ring 104, the outer ring 104 is fixedly connected to the inner wall of the kettle body 1 to ensure the overall stability of the guide ring 101, and the inner ring 105 is clamped inside the outer ring 104, and a circle of narrow and precise guide channel 106 is formed between the two, and the inner ring 105 It can also be easily removed from the outer ring 104. The design of the guide channel 106 fully considers the movement requirements of the stirring and grinding component 3. When the stirring shaft 2 drives multiple stirring and grinding components 3 to rotate, one end of the stirring and grinding component 3 will fit tightly in the guide channel 106, that is, the stirring and grinding component 3 will respectively resist the inner ring 105 and the outer ring 104, ensuring that its movement in the horizontal direction is both stable and efficient, further improving the mixing uniformity of the material, allowing the stirring and grinding component 3 to move along the guide channel 106, without the need for an additional driving source, the stirring and grinding component 3 can be translated along its radial path on the guide plate 201, which can not only complete the grinding action of the stirring and grinding component 3, but also increase the stirring range of the stirring and grinding component 3.

[0039] In a further embodiment of the present invention, the stirring and grinding assembly 3 includes a stirring rod 301 that passes through the guide plate 201, and the guide plate 201 is provided with a guide rail 202 for the stirring rod 301 to move. The top of the stirring rod 301 passes through the guide rail 202 and is rotatably connected to a connecting rod 302, one end of the connecting rod 302 is vertically fixedly connected to an insertion rod 303, the insertion rod 303 is inserted into the guide ring 101, and a sleeve 304 is sleeved on the stirring rod 301, and a rolling plate 305 is fixedly connected to one side of the sleeve 304. Specifically, the stirring rod 301 can translate along the guide rail 202 specially provided on the guide plate 201, ensuring that the stirring rod 301 can move up and down along a predetermined trajectory while rotating. The stirring shaft 202 is driven by the driving motor 204 to rotate with the guide plate 201 and the stirring rod 301. The stirring rod 301 is guided by the guide ring 101 and moves radially along the guide rail 202 on the guide plate 201. The connecting rod 302 is closely matched with the guide ring 101 through the insertion rod 303, thereby ensuring the stability and guidance of the stirring and grinding assembly 3. At the same time, the rolling plate 305 on one side of the stirring rod 301 will continuously grind and crush the material with the movement of the stirring rod 301, thereby realizing efficient mixing and refinement of the material, which not only improves the preparation efficiency of liquid organic fertilizer, but also further improves the quality of organic fertilizer.

[0040] In a further embodiment of the present invention, a connecting ring 5 is rotatably embedded on the stirring shaft 2, and a plurality of scraper frames 501 are distributed in an annular manner on the outer side of the connecting ring 5. The rolling plate 305 is located in the scraper frame 501, and the scraper frame 501 is in contact with the two sides of the rolling plate 305 respectively. Specifically, when the stirring shaft 2 rotates under the action of the driving force, each stirring rotating rod 301 synchronously pushes the scraper frame 501 on the connecting ring 5. Since the scraper frame 501 is tightly fitted with the two sides of the rolling plate 305, and the rolling plate 305 is moved by the scraper frame 501, when the rolling plate 305 moves in and out During the process of the material trough 103, the inner wall sides of the scraper frame 501 can effectively scrape off the residual materials attached to the rolling plate 305, preventing the materials from accumulating or adhering to the surface of the rolling plate 305 during the rolling process, thereby ensuring the uniformity and continuity of the rolling effect. This design not only improves the cleaning efficiency of the equipment, but also significantly optimizes the material processing flow, and allows the rolling plate 305 to enter and move out of the material trough 103 in a straight line without affecting the rotation of the stirring connecting rod, ensuring that the surface of the rolling plate 305 can contact the material in the kettle body 1 to the greatest extent.

[0041] In a further embodiment of the present invention, a transmission gear 306 is fixedly sleeved on the stirring rod 301, and a transmission rack 203 meshing with the transmission gear 306 is horizontally fixedly connected to the bottom of the guide plate 201. Specifically, a horizontal transmission rack 203 at the bottom of the guide plate 201 and the transmission gear 306 are meshed with each other, so that the guide plate 201 can not only realize the material guiding function, but also can drive the stirring rod 301 therein to rotate through the transmission rack 203 while the stirring and grinding assembly 3 radially reciprocates along the guide plate 201, so that the stirring shaft 2 can translate in the kettle body 1 while itself rotating to improve the mixing and fermentation efficiency of the material in the kettle body 1.

Specifically, when the stirring shaft 2 rotates, the upper stirring frame 6 and the lower stirring frame 7 are driven to rotate together, and the upper stirring frame 6 can move up and down along the stirring shaft 2 within a certain range. The abutment block 307 at the bottom of the stirring rod 301 passes through the wedge-shaped groove 601 and abuts against the upper stirring frame 6. Therefore, when the stirring rod 301 approaches the stirring shaft 2 under the guidance of the guide ring 101, the inclined abutment between the abutment block 307 and the upper stirring frame 6 will cause the upper stirring frame 6 to be forced to lift during the rotation. When the stirring rod 301 moves in the opposite direction, the upper stirring frame 6 will drop under the action of gravity, so that the stirring shaft 2 can not only drive the upper stirring frame 6 to perform more complex stirring actions, but also achieve all-round, multi-angle and high-efficiency mixing of materials in the stirring container through the coordinated work of the upper stirring frame 6 and the lower stirring frame 7, thereby significantly improving the stirring effect and material uniformity.

[0043] In a further embodiment of the present invention, a material shifting piece 308 is fixedly connected to the other end of the connecting rod 302, and the material shifting piece 308 is in contact with the top surface of the guide plate 201.
