Description

Technical Field

[0001] This utility model relates to the technical field of organic fertilizer production equipment, and in particular to a vertical microbial agent addition and mixing machine for organic fertilizer production. Background Technology

[0002] In existing technologies, the production of organic fertilizers requires the addition of biological agents to ferment the materials. Currently, there are many types of agent mixing and adding equipment available on the market, each with its own advantages and disadvantages.

[0003] Chinese Patent (Patent Application No. 202421739418.X) discloses a "Bio-organic Fertilizer Addition Tank Equipment," belonging to the field of feeding equipment technology. It aims to solve the technical problem that, under existing technologies, some bio-organic fertilizer and microbial agents tend to settle at the bottom of the tank during the addition process, making it difficult to ensure the uniform dispersion of the microbial agents in the bio-organic fertilizer, thus reducing the uniformity of bio-organic fertilizer addition and its effectiveness. This bio-organic fertilizer addition tank equipment includes an addition tank body for mixing bio-organic fertilizer with microorganisms. A shaft is vertically and rotatably mounted inside the addition tank. At least one pair of first stirring components are radially arranged at the bottom end of the shaft. The first stirring component includes an integrally formed inclined support plate and a first curved shovel plate. This bio-organic fertilizer addition tank equipment, through shoveling, conveying, pushing, freely scattering, and scraping of the bio-organic fertilizer and microbial colonies within the addition tank, can ensure the uniform dispersion of the added bio-organic fertilizer within the addition tank, achieving uniform bio-organic fertilizer addition.

[0004] Another Chinese patent (patent application number 202411334460.8) discloses a "vertical stirring device and vertical stirring method for achieving cyclic mixing," which includes a stirring device, a container, a control device, and a discharge container. The stirring device includes a motor, a stirring rod, an ascending spiral ribbon, a descending spiral ribbon, ribs, and bottom irregularly shaped blades. The motor is located at the center of the stirring container and is connected to the stirring rod via a coupling, providing rotational power to the stirring rod to make it rotate. The stirring rod connects the ascending spiral ribbon, the descending spiral ribbon, and the ribs, so that when the stirring rod rotates, it drives the ascending spiral ribbon, the descending spiral ribbon, and the ribs to rotate. The ascending spiral ribbon transports the outer solution upwards when rotating. The descending spiral ribbon is located inside the ascending spiral ribbon and transports the inner solution downwards when rotating, forming a cyclic stirring with the ascending spiral ribbon. The ribs are used to connect the ascending spiral ribbon and the descending spiral ribbon. The bottom irregularly shaped blades are used to stir the bottom solution. This invention also provides a vertical stirring method for achieving cyclic mixing, based on the above-described vertical stirring device.

[0005] Another Chinese patent (patent application number 202510048778.8) discloses "An Automatically Rotating Vertical Ribbon Mixer," which includes a mixer body with a ribbon agitator inside. The ribbon agitator includes a rotating shaft and a ribbon. A spherical bearing is installed on the top of the mixer body, and the upper end of the rotating shaft is inserted into the spherical bearing. A housing is installed on top of the spherical bearing, and a reducer for driving the rotating shaft is installed inside the housing. A motor for driving the reducer is installed on the outside of the housing. An electric push rod is installed on the top of the mixer body, and the telescopic end of the electric push rod is rotatably connected to the housing. A limit rod is installed on the outside of the rotating shaft. An annular groove is formed on the inner wall of the mixer body, and the end of the limit rod is inserted into the inner side of the annular groove. The motor drives the reducer to rotate the ribbon agitator. Through the cooperation of the limit rod and the annular groove, the electric push rod drives the ribbon agitator to revolve, reducing the load on the electrical connection and making the mixer body more economical and efficient. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a bacterial agent addition and mixing device with simple structure and good mixing effect.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is to design a vertical microbial agent addition and mixing machine for organic fertilizer production: it includes a mixing cylinder assembly, which includes a mixing cylinder body 9, a top bridge plate 3, and a bottom surface 11 of the mixing cylinder body. The top bridge plate 3 and the bottom surface 11 of the mixing cylinder body are respectively disposed at the upper end and the lower end of the mixing cylinder body 9; it also includes a power assembly, a downward conveying assembly, an upward tilting assembly, and a cylinder wall scraping assembly. The power assembly is disposed in the inner cavity of the mixing cylinder body 9 and on the top bridge plate 3. The upward tilting assembly and the downward conveying assembly are respectively disposed on the power assembly in the inner cavity of the mixing cylinder body 9. The cylinder wall scraping assembly is disposed around the upward tilting assembly and the downward conveying assembly in the inner cavity of the mixing cylinder body 9.

[0008] The power assembly includes a geared motor 1, a main shaft 2, an upper bearing seat 4, and a lower bearing seat 13. The upper bearing seat 4 and the lower bearing seat 13 are respectively located in the middle of the top bridge plate 3 and the bottom surface 11 of the mixing cylinder. The upper end of the main shaft 2 passes through the upper bearing seat 4 from the inner cavity of the mixing cylinder 9 and then passes into the output shaft hole of the geared motor 1 located on the top bridge plate 3. Its lower end passes into the lower bearing seat 13. The lower feeding assembly and the upper tilting assembly are respectively located in the upper middle part and the lower middle part of the main shaft 2.

[0009] The lower feeding assembly includes two or more sets of upper and lower feeding blades 5 and middle and lower feeding blades 7; the blade surfaces of the upper and lower feeding blades 5 and the middle and lower feeding blades 7 are curved, and one end of each blade is connected to the upper and middle parts of the main shaft 2, respectively, and the length of the middle and lower feeding blades 7 is 30-50% of the length of the upper and lower feeding blades 5.

[0010] The upper and lower parts of the blades of the upper and lower stirring blades 5 and the middle and lower stirring blades 7 are respectively formed by two curved surfaces with opposite bending directions tangent to each other.

[0011] The curvature of the upper and lower stirring blades 5 and the middle and lower stirring blades 7 gradually decreases from the outer end to the middle end of the main shaft 2.

[0012] The upward-turning assembly includes two or more sets of lower upward-turning stirring blades 10 and middle upward-turning stirring blades 8; the lower upward-turning stirring blades 10 and middle upward-turning stirring blades 8 have the same blade surface as the upper and lower feeding stirring blades 5 and the middle and lower feeding stirring blades 7, but the bending direction is opposite. One end of the lower upward-turning stirring blade 10 is connected to the lower part of the main shaft 2, and one end of the middle upward-turning stirring blade 8 is connected to the outer end of the middle and lower feeding stirring blade 7 through the connecting block 14, and the length of the middle upward-turning stirring blade 8 is 30-50% of the length of the lower upward-turning stirring blade 10.

[0013] The curvature of the blades of the lower and upper tumbling blades 10 and the middle and upper tumbling blades 8 gradually increases from the outer end to the middle end of the main shaft 2.

[0014] The cylinder wall scraping assembly includes two or more sets of cylinder wall scraping rods 6, and the inner sides of the cylinder wall scraping rods 6 are respectively connected to the outer ends of the upper and lower feeding and stirring blades 5, the middle and upper turning and stirring blades 8 and the lower and upper turning and stirring blades 10.

[0015] The front side of the cylindrical wall scraper 6 is an acute angle formed by the intersection of two curved surfaces, and the acute angle is 10-30°.

[0016] A discharge hopper 16 is also provided at the lower part of the mixing cylinder 9, and a discharge plate 15 is also provided on the discharge hopper 16.

[0017] This utility model discloses a vertical microbial agent addition and mixing machine for organic fertilizer production. It features two sets of downward conveying components and upward tilting components mounted on the same main shaft, with identical blade surfaces but opposite curvature directions. The curvature of the two sets of blade surfaces also changes in opposite directions. This ensures that during the mixing process, as the material is pushed downwards by the downward conveying components, it gradually moves towards the center, while the material is gradually moved towards the edge as it is tilted upwards by the upward tilting components. Therefore, it can quickly mix the material and facilitates the discharge of the mixed material from the outlet hopper. Consequently, its structure is relatively simple, and the mixing effect is good.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments. The following description is by way of example, but the scope of protection of the present invention should not be limited thereto.

[0030] Example:

[0031] The organic fertilizer compound turning machine in this embodiment consists of a mixing cylinder assembly, a power assembly, a lower conveying assembly, an upper turning assembly, and a cylinder wall scraping assembly.

[0032] The mixing cylinder assembly consists of a mixing cylinder body 9, a top bridge plate 3, a bottom surface of the mixing cylinder body 11, cylinder feet 12, and a discharge hopper 16.

[0033] The mixing cylinder 9 is a cylindrical body with a top bridge plate 3 (the top bridge plate 3 is a rectangular plate with arcs at both ends that match the top surface of the mixing cylinder 9) on its upper end and a bottom surface 11 on its lower end, forming a cylinder with a bottom surface. Three or more (four evenly distributed in this example) cylinder feet 12 are also provided below the bottom surface 11 of the mixing cylinder. A hole is opened on one side of the lower part of the mixing cylinder 9 and a discharge hopper 16 is installed for discharging material. A discharge control plate 15 is also provided on the discharge hopper 16 to control the discharge.

[0034] The power assembly consists of a geared motor 1, a main shaft 2, an upper bearing housing 4, and a lower bearing housing 13.

[0035] The geared motor 1 is a motor with a speed reduction device (such as a worm gear reducer); the upper bearing housing 4 and the lower bearing housing 13 can be sliding bearing housings or rolling bearing housings, which are respectively set in the middle of the top bridge plate 3 and the bottom surface 11 of the mixing cylinder; the main shaft 2 is a two-way stepped shaft, whose upper end passes through the inner cavity of the mixing cylinder 9, passes through the upper bearing housing 4, and then passes through the output shaft hole of the geared motor 1 set on the top bridge plate 3, and its lower end passes through the lower bearing housing 13.

[0036] The lower feeding assembly consists of two or more sets (in this example, four blades arranged symmetrically in pairs) of upper and lower feeding blades 5 and middle and lower feeding blades 7. One end of each blade is connected to the upper and middle parts of the main shaft 2, respectively. The length of the middle and lower feeding blades 7 is 30-50% of the length of the upper and lower feeding blades 5. Furthermore, the blade surfaces of the upper and lower feeding blades 5 and the middle and lower feeding blades 7 are curved, with the upper and lower parts of each blade surface formed by two tangent curved surfaces in opposite directions. The curvature of the blade surface gradually decreases from the outer end to the middle end of the main shaft 2 (to facilitate the upper and lower feeding blades 5 and the middle and lower feeding blades 7 pushing the material from the upper part to the middle part, see Appendix). Figure 1 (As shown by the double-dotted arrow in the image).

[0037] The upward-turning assembly consists of two or more sets (in this example, four blades arranged symmetrically in pairs) of lower upward-turning stirring blades 10 and middle upward-turning stirring blades 8. The lower upward-turning stirring blades 10 and middle upward-turning stirring blades 8 have the same blade surface as the upper and lower feeding stirring blades 5 and the middle and lower feeding stirring blades 7, but their curvature is opposite. One end of the lower upward-turning stirring blade 10 is connected to the lower part of the main shaft 2, and one end of the middle upward-turning stirring blade 8 is connected to the outer end of the middle and lower feeding stirring blades 7 (i.e., the end not connected to the main shaft 2) through a connecting block 14. The length of the middle upward-turning stirring blade 8 is 30-50% of the length of the lower upward-turning stirring blade 10. The curvature of the blade surface of the lower upward-turning stirring blades 10 and middle upward-turning stirring blades 8 gradually increases from the outer end to the middle end of the main shaft 2 (to facilitate the lower upward-turning stirring blades 10 and middle upward-turning stirring blades 8 to turn the material in the middle and lower parts towards the upper edge, see Appendix). Figure 1 (As shown by the double-dotted arrow in the image).

[0038] The cylinder wall scraping assembly consists of two or more sets (in this example, four rods arranged symmetrically in pairs) of cylinder wall scraping rods 6. The inner side of the cylinder wall scraping rods 6 is connected to the upper and lower stirring blades 5 (i.e., the end not connected to the main shaft 2), the middle and upper stirring blades 8 (the end not connected to the middle and lower stirring blades 7), and the outer end of the lower and upper stirring blades 10 (i.e., the end not connected to the main shaft 2). The front side of the cylinder wall scraping rods 6 is an acute angle formed by the intersection of two curved surfaces, and the acute angle is 10-30°.

[0039] In use, first turn on the reduction motor 1. The main shaft 2 drives the upper and lower stirring blades 5, the middle and lower stirring blades 7, together with the middle and upper turning stirring blades 8 and the lower and upper turning stirring blades 10 to rotate clockwise. Then, add the material and the inoculant into the inner cavity of the mixing cylinder 9 through the upper port (excluding the empty space outside the top bridge plate 3). At this time, the material in the upper part of the inner cavity of the mixing cylinder 9 is pushed to the middle and lower part by the upper and lower stirring blades 5 and the middle and lower stirring blades 7, and gathers towards the middle (i.e., the part of the main shaft 2). Meanwhile, the material in the lower part of the inner cavity of the mixing cylinder 9 is pushed to the middle and upper part by the lower and upper turning stirring blades 10 and the middle and upper turning stirring blades 8, and gathers towards the edge (i.e., the edge part of the inner cavity of the mixing cylinder 9), forming an up-and-down cyclical flipping, so that the material and the inoculant can be mixed evenly as quickly as possible.

[0040] After the material and the inoculant are mixed evenly, the discharge plate 15 is pulled upwards, and the evenly mixed material can be discharged from the discharge hopper 16.

[0041] This utility model relates to a vertical microbial agent addition and mixing machine for organic fertilizer production, which is suitable for uniform mixing after the addition of microbial agents in the production process of various organic fertilizers.
