Description

Technical Field

[0001] This utility model relates to the field of compound microbial fertilizer production technology, specifically a mixing and stirring device for compound microbial fertilizer. Background Technology

[0002] Compound microbial fertilizers are live microbial products composed of specific microorganisms and nutrients, which can provide, maintain, or improve plant nutrition, increase agricultural product yield, or improve agricultural product quality. They combine the characteristics of both microbial fertilizers and organic fertilizers, containing beneficial microbial flora such as bacteria, fungi, and actinomycetes, as well as a certain amount of organic matter, nutrients such as nitrogen, phosphorus, and potassium, and other active substances.

[0003] Compound microbial fertilizers contain various beneficial microbial agents, such as Bacillus subtilis, Bacillus licheniformis, phosphate-solubilizing bacteria, and potassium-solubilizing bacteria. During the production of compound microbial fertilizers, stirring ensures that these different types of microbial agents are evenly dispersed in the fertilizer system. This guarantees that when the fertilizer is used, the soil or plant roots in contact with it have a sufficient number and variety of beneficial microorganisms, thus allowing them to fully exert their respective effects.

[0004] The existing patent document with authorization announcement number CN222489915U describes a mixing and stirring device for the production of compound microbial fertilizer, including a mixing tank with a sealing cover bolted to the upper end; an agitator bolted to the upper part of the sealing cover, with the agitator inserted into the interior of the mixing tank from below; and a material injection head welded to the left side inside the sealing cover. This technical solution supports the mixing tank and achieves bottom sealing protection through the arrangement of a support plate, support column, and sealing seat. However, during the stirring process, due to the inability to utilize the properties of the material and the combined action of the stirring blades and stirring rods, the material will form different flow zones within the mixing tank, affecting the mixing effect. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a mixing and stirring device for compound microbial fertilizers. This device solves the problem that the material's properties and the combined action of the stirring blades and stirring rods cause different flow zones within the mixing tank, affecting the mixing effect. The stirring blades exert shearing and compressing forces on the material, breaking down large particles and allowing materials of different components to interweave and mix, achieving uniform mixing. During the stirring process, due to the material's properties and the combined action of the stirring blades and stirring rods, different flow zones form within the mixing tank. These flows superimpose, further improving the mixing effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mixing and stirring device for compound microbial fertilizer, comprising a tank assembly, a feeding assembly, and a stirring assembly. The tank assembly includes a mixing tank, the feeding assembly includes a first motor and a linkage rod, and the stirring assembly includes a second motor, a stirring shaft, and a linkage bottom rod. A feeding side cylinder is provided inside the mixing tank, and a guide layer groove is formed in the wall of the feeding side cylinder. A discharge bottom pipe with a valve is connected to the bottom of the mixing tank. Guide blades are connected to the outer wall of the linkage rod. A first sleeve and a second sleeve are connected to the outer wall of the stirring shaft. A stirring layer rod is connected to the outer wall of the first sleeve, and stirring blades are connected to the outer wall of the second sleeve. A discharge brush is connected to the bottom of the linkage bottom rod.

[0007] The beneficial effects of this utility model are as follows: The second motor drives the second sleeve to rotate through the stirring shaft, and the stirring blades installed on the second sleeve rotate accordingly. During the rotation of the stirring blades, on the one hand, the stirring blades push the material to make a circular motion, so that the material forms a circulation in the mixing tank. On the other hand, the stirring blades generate shearing and squeezing action on the material, breaking down large particles and allowing materials of different components to interweave and mix with each other, so as to achieve the purpose of uniform mixing. During the stirring process, due to the properties of the material and the combined action of the stirring blades and the stirring rod, the material will form different flow zones in the mixing tank. These flows superimpose each other, further improving the mixing effect of the material.

[0008] To leverage the corrosion resistance, wear resistance, and insulation properties of the corrosion-resistant layer, while maintaining light weight and high strength, thereby reducing corrosion of the mixing tank by chemicals in the material and extending the service life of the equipment:

[0009] As a further improvement to the above technical solution: the inner wall of the mixing tank is connected to a corrosion-resistant layer, which is a fiberglass layer and is installed on the inner wall of the mixing tank by an adhesive.

[0010] The beneficial effects of this improvement are as follows: When installing the corrosion-resistant layer, it is cut to a suitable size and shape according to the internal dimensions and shape of the mixing tank, with a predetermined allowance left during cutting for subsequent installation and adjustment. After cutting, an adhesive is evenly applied to the inner surface of the mixing tank and the bonding surface of the corrosion-resistant layer. The corrosion-resistant layer with the adhesive applied is then placed into the mixing tank for installation. After installation, the adhesive is allowed to cure under certain temperature and humidity conditions according to its curing requirements. The corrosion-resistant layer's corrosion resistance, wear resistance, and insulation properties, combined with its light weight and high strength, reduce the corrosion of the mixing tank by chemicals in the material, extending the service life of the equipment.

[0013] The beneficial effects of this improvement are as follows: When in use, materials are added into the feed side cylinder through the feed top inlet, and the falling materials flow into the mixing tank in layers through the guide trough, thereby dispersing the materials to various height positions in the mixing tank and improving the mixing efficiency.

[0014] In order for the first motor to work and drive the rotation of the linkage rod and the guide blades, the material is then spiraled downwards under the action of the guide blades:

[0015] As a further improvement to the above technical solution: the first motor is mounted on the bottom of the mixing tank by a bracket and is electrically connected to the operation panel; the top of the linkage rod is connected to the output end of the first motor by a coupling; and the end of the linkage rod away from the first motor is rotatably connected to the inner wall of the feed side cylinder by a bearing.

[0016] The beneficial effects of this improvement are as follows: the first motor starts running, the first motor works and drives the linkage rod and the guide blade to rotate, thereby causing the material to fall spirally under the action of the guide blade.

[0017] For the installation and fixation of the feed side cylinder inside the mixing tank, and by installing and fixing the feed side cylinder inside the mixing tank:

[0018] As a further improvement to the above technical solution: the outer wall of the feed side cylinder is connected to a positioning outer ring, which is installed on the outer wall of the feed side cylinder at equal intervals by bolts. The end of the positioning outer ring away from the feed side cylinder penetrates the corrosion-resistant layer and is connected to the inner wall of the mixing tank.

[0019] The beneficial effects of this improvement are: by setting the positioning outer ring, the feed side cylinder is installed and fixed inside the mixing tank, and by installing and fixing the feed side cylinder inside the mixing tank, the installation and positioning of the feed side cylinder is achieved.

[0020] To use the stirring bar for mixing and agitating the material discharged from the feed trough:

[0021] As a further improvement to the above technical solution: the second motor is a planetary gear reducer motor installed on the top of the mixing tank and electrically connected to the operation panel. One end of the stirring shaft passes through the top wall of the mixing tank and extends to be connected to the output end of the second motor through a coupling. The stirring shaft is rotatably connected to the top wall of the mixing tank through a bearing. The end of the stirring shaft away from the second motor is rotatably connected to the inner wall of the mixing tank through a bearing.

[0022] The beneficial effects of this improvement are as follows: after the second motor is started, the second motor works and drives the rotation of the stirring shaft and the stirring rod, and the stirring rod is used to mix and stir the material discharged from the guide trough.

[0023] To ensure that the materials form different flow zones within the mixing tank, these flows overlap to further improve the mixing effect:

[0024] As a further improvement to the above technical solution: the stirring blades are symmetrically installed on the outer wall of the second sleeve, and both the first sleeve and the second sleeve are connected to the stirring shaft by bolts, and the stirring blades and the stirring layer rods are arranged at intervals in sequence.

[0025] The beneficial effects of this improvement are as follows: The second motor drives the second sleeve to rotate through the stirring shaft, and the stirring blades installed on the second sleeve rotate accordingly. During the rotation of the stirring blades, on the one hand, the stirring blades push the material to make a circular motion, so that the material forms a circulation in the mixing tank. On the other hand, the stirring blades exert a shearing and squeezing effect on the material, breaking down large particles and allowing materials of different components to interweave and mix, so as to achieve the purpose of uniform mixing. During the stirring process, due to the properties of the material and the combined action of the stirring blades and the stirring rod, the material will form different flow zones in the mixing tank. These flows superimpose each other, further improving the mixing effect of the material.

[0026] In order for the linkage bottom rod to drive the discharge brush to push the material accumulated at the bottom of the mixing tank during rotation, so as to facilitate the material to be discharged from the discharge bottom pipe:

[0027] As a further improvement to the above technical solution: the stirring shaft is connected to four linkage bottom rods on the outer wall near the bottom surface of the mixing tank, and the end of the discharge brush away from the linkage bottom rods is in contact with the bottom surface wall of the mixing tank.

[0028] The beneficial effects of this improvement are as follows: when the linkage bottom rod rotates under the drive of the stirring shaft, the linkage bottom rod drives the discharge brush to push the material accumulated at the bottom of the mixing tank, thereby facilitating the discharge of the material from the discharge bottom pipe.

The inner wall of the mixing tank 11 is connected to a corrosion-resistant layer 12, which is a fiberglass layer and is installed on the inner wall of the mixing tank 11 with an adhesive. When installing the corrosion-resistant layer 12, it is cut to a suitable size and shape according to the internal dimensions and shape of the mixing tank 11, leaving a predetermined allowance for subsequent installation and adjustment. After cutting, an adhesive layer is evenly applied to the inner surface of the mixing tank 11 and the mating surface of the corrosion-resistant layer 12. The corrosion-resistant layer 12 with the adhesive applied is then placed into the mixing tank 11 for installation. After installation, the adhesive is allowed to cure for a certain period of time according to the curing requirements. Curing is carried out under temperature and humidity conditions. The corrosion-resistant layer 12 possesses corrosion resistance, wear resistance, and insulation properties, while being lightweight and high-strength. This reduces the corrosion of the mixing tank 11 by chemicals in the material, extending the service life of the device. There are two symmetrically arranged feed side cylinders 13, each with a feed top inlet 14 connected to its top. The guide grooves 15 are longitudinally layered at equal intervals. The bottom of each feed side cylinder 13 is 30 mm from the inner wall of the bottom surface of the mixing tank 11. In use, material is added to the feed side cylinder 13 through the feed top inlet 14. The falling material flows through the guide grooves 15 in layers into the mixing tank 11, dispersing the material to various height positions within the mixing tank 11 and improving mixing efficiency. The motor 21 is mounted on the bottom of the mixing tank 11 via a bracket and is electrically connected to the operation panel. The top of the linkage rod 22 is connected to the output end of the first motor 21 via a coupling. The end of the linkage rod 22 away from the first motor 21 is rotatably connected to the inner wall of the feed side cylinder 13 via a bearing. When the first motor 21 is started, it works and drives the linkage rod 22 and the guide blade 23 to rotate, thereby causing the material to spiral down under the action of the guide blade 23. The outer wall of the feed side cylinder 13 is connected to a positioning outer ring 24. The positioning outer ring 24 is installed on the outer wall of the feed side cylinder 13 at equal intervals via bolts. The end of the positioning outer ring 24 away from the feed side cylinder 13 penetrates the corrosion-resistant layer 12 and is connected to the inner wall of the mixing tank 11.The positioning outer ring 24 is used to install and fix the feed side cylinder 13 inside the mixing tank 11. By installing and fixing the feed side cylinder 13 inside the mixing tank 11, the installation and positioning of the feed side cylinder 13 is achieved. The second motor 31 is a planetary gear reducer motor installed on the top of the mixing tank 11 and electrically connected to the operation panel. One end of the stirring shaft 32 penetrates the top wall of the mixing tank 11 and extends to be connected to the output end of the second motor 31 via a coupling. The stirring shaft 32 is rotatably connected to the top wall of the mixing tank 11 via bearings. The end of the stirring shaft 32 furthest from the second motor 31 is rotatably connected to the inner wall of the mixing tank 11 via a bearing; after the second motor 31 is started, it operates and drives the stirring shaft 32 and the stirring rod 34 to rotate, and the stirring rod 34 is used to mix and stir the material discharged from the feed trough 15. The stirring blades 36 are symmetrically installed on the outer wall of the second sleeve 35. The first sleeve 33 and the second sleeve 35 are both connected to the stirring shaft 32 by bolts. The stirring blades 36 and the stirring rod 34 are arranged alternately in sequence. The second motor 31 drives the second sleeve 35 to rotate via the stirring shaft 32. The stirring blades 36 mounted on the second sleeve 35 rotate accordingly. During rotation, the stirring blades 36 push the material in a circular motion, creating a circulation within the mixing tank 11. Simultaneously, the stirring blades 36 shear and compress the material, breaking down large particles and allowing materials of different compositions to interweave and mix, achieving uniform mixing. During the mixing process, due to the properties of the material and the combined action of the stirring blades 36 and the stirring rod 34, the material will... Different flow zones are formed within the mixing tank 11. These flows overlap, further improving the mixing effect on the materials. Four linkage rods 37 are connected to the outer wall of the mixing shaft 32 near the bottom surface of the mixing tank 11. The end of the discharge brush 38 away from the linkage rods 37 is in contact with the bottom wall of the mixing tank 11. When the linkage rods 37 rotate under the drive of the mixing shaft 32, they drive the discharge brush 38 to push the material accumulated at the bottom of the mixing tank 11, thus facilitating the discharge from the discharge pipe 16.

[0039] The working principle of this utility model is as follows: During use, material is added into the feed side cylinder 13 through the feed top port 14. The first motor 21 is started, driving the linkage rod 22 and the guide blades 23 to rotate. This causes the material to spirally fall under the action of the guide blades 23. The falling material flows in layers through the guide layer groove 15 into the mixing tank 11, dispersing the material to various height positions within the mixing tank 11 and improving mixing efficiency. After starting the second motor 31, it drives the stirring shaft 32 and the stirring layer rod 34 to rotate, and through the stirring layer rod 3... 4. Used for mixing and stirring the material discharged from the feed trough 15, the second motor 31 drives the second sleeve 35 to rotate via the stirring shaft 32. The stirring blades 36 installed on the second sleeve 35 rotate accordingly. During the rotation, the stirring blades 36 push the material to make circular motion, so that the material forms a circulation in the mixing tank 11. On the other hand, the stirring blades 36 exert a shearing and squeezing effect on the material, breaking down large particles and allowing materials of different compositions to interweave and mix, achieving the purpose of uniform mixing. During the stirring process, due to the properties of the material and the combined action of the stirring blades 36 and the stirring rod 34, the material will move in the mixing tank. Different flow zones are formed within the mixing tank 11. These flows overlap, further improving the mixing effect of the materials. When the linkage bottom rod 37 rotates under the drive of the stirring shaft 32, the linkage bottom rod 37 drives the discharge brush 38 to push the material accumulated at the bottom of the mixing tank 11, thereby facilitating the discharge of the material from the discharge bottom pipe 16. The positioning outer ring 24 is used for the installation and fixation of the feed side cylinder 13 inside the mixing tank 11. By installing and fixing the feed side cylinder 13 inside the mixing tank 11, the installation and positioning of the feed side cylinder 13 are achieved. When installing the corrosion-resistant layer 12, it is done according to the dimensions inside the mixing tank 11. The corrosion-resistant layer 12 is cut to a suitable size and shape, leaving a predetermined allowance for subsequent installation and adjustment. After cutting, an adhesive layer is evenly applied to the inner surface of the mixing tank 11 and the mating surface of the corrosion-resistant layer 12. The corrosion-resistant layer 12 with the adhesive applied is then placed into the mixing tank 11 for installation. After installation, the adhesive is allowed to cure under certain temperature and humidity conditions according to its curing requirements. The corrosion-resistant layer 12 has corrosion resistance, wear resistance, and insulation properties, and is lightweight and high-strength, which reduces the corrosion of the mixing tank 11 by chemicals in the material and extends the service life of the equipment.
