Abstract

This invention relates to the field of microbial agent mixing and cell wall breaking technology, specifically a composite microbial solid agent mixing and homogenizing machine. The intermediate floating plate is equipped with multiple sets of positioning rings corresponding eccentrically to a fine filter screen. Each positioning ring contains a compression bladder. An air bladder, fitted to the lower outer wall of the compression bladder and the lower surface of the intermediate floating plate, is located in the upper insert. The beneficial effects are as follows: by setting a rotating plate with air bladder protection, when the crushing rollers compress and break the cell wall, the granular microbial agent is separated and broken by the coarse filter screen and falls into the intermediate floating plate. During compression with the intermediate floating plate, the air bladder provides unidirectional compression buffering. Excessive compression is pressed into the positioning rings by the fine filter screen. Automatic material discharge is achieved by rotating the plate. A telescopic vibration component drives the intermediate floating plate within the rotating plate cavity to telescopically vibrate at the upper end of the cell wall breaking plate. Combined with the compression of the air bladder by the crushing rollers, sieving-type material discharge is achieved, fully realizing sieving-type material discharge while protecting the microorganisms.

Description

Technical Field

[0001] This invention relates to the field of mixing and cell wall breaking technology of microbial agents, specifically a composite microbial solid agent mixing machine. Background Technology

[0002] Microbial inoculants are widely used in agricultural planting and animal and plant breeding due to their special effects. Most microbial inoculants are in the form of powder or granular solids.

[0003] In existing technologies, in order to maintain the activity of microorganisms, most microorganisms are encapsulated in sealed particles to prevent moisture loss and avoid inactivation of microbial agents.

[0004] In practical use, seed dressing agents are usually added to microbial agents. However, after the microbial agents are encapsulated into isolated particles, they are difficult to mix with the seed dressing agents. They usually need to be dissolved first, then dried, and then mixed, which greatly increases the cost and time of mixing. Traditional extrusion and cell wall breaking methods break the particles to achieve mixing, but it is difficult to ensure the size of the broken particles. Excessive cell wall breaking can easily cause microbial ignition and affect the quality. Summary of the Invention

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 13 The present invention provides a technical solution:

[0039] A composite microbial solid inoculant seed mixing machine, comprising a mixing tank 1, a tilting plate 2, an extrusion and cell-wall breaking component, and a telescopic vibration component.

[0040] The lower end of the mixing tank 1 is provided with an annular stirring trough 16, and a stirring rod 11 driven by a stirring motor 13 is provided in the stirring trough 16.

[0041] The stirring rod 11 driven by the stirring motor 13 achieves thorough mixing of the microbial inoculant and seed dressing agent in the mixing tank 16.

[0042] The tilting plate 2 is rotatably installed in the upper inner cavity of the mixing tank 1. The inner cavity of the tilting plate 2 is provided with a double-layer structure of lower insert 29 and upper insert 30. The upper end of the tilting plate 2 is provided with a wall-breaking plate 18 for collecting granular solid bacterial agents. The wall-breaking plate 18 includes a coarse filter 19 and multiple sets of fine filters 35 distributed in a matrix. The coarse filter 19 and the fine filters 35 are separated by a separating ring 21. A middle float 38 is rotatably inserted into the lower insert 29. The middle float 38 can be rotated on both sides by rotating the middle float 38, thereby achieving the purpose of squeezing the airbag 8 to achieve the purpose of squeezing and buffering.

[0043] The intermediate float plate 38 is provided with multiple sets of positioning rings 41 that are eccentrically corresponding to the fine filter screen 35. The positioning rings 41 are provided with compression bladders 39. The upper insert layer 30 is provided with airbags 8 that fit the lower outer wall of the compression bladder 39 and the lower end surface of the intermediate float plate 38.

[0044] By setting eccentrically distributed positioning rings 41 and separating rings 21, staggered support is achieved, which improves the support of the filter screen during extrusion and cell wall breaking and avoids deformation.

[0045] The extrusion cell wall breaking component includes a dual-axis displacement drive component and a motor-driven crushing roller 6. The crushing roller 6 presses against the cell wall breaking plate 18. Through the extrusion of the crushing roller 6, the purpose of extrusion cell wall breaking is achieved, thereby causing the granular microbial agent to be crushed by the filter screen and fall between the intermediate floating plate 38 and the cell wall breaking plate 18.

[0046] The telescopic vibration assembly includes a telescopic hydraulic cylinder 27 and a rotating connecting rod 23 fixed on the inner wall of the mixing tank 1. A column 24 is vertically arranged at the telescopic end of the telescopic hydraulic cylinder 27. One end of the rotating connecting rod 23 is rotatably connected to the intermediate float 38. The outer end of the rotating connecting rod 23 is attached to the column 24 and achieves telescopic sliding under the drive of the telescopic hydraulic cylinder 27.

[0047] The material is discharged by flipping, and the column 24 is driven to move laterally by the telescopic hydraulic cylinder 27, so as to achieve the purpose of traction of the intermediate float 38 to move laterally. This causes the positioning ring 41 to slide laterally on the upper end of the wall-breaking plate 18, so as to achieve the purpose of vibration and squeezing the microbial agent after wall breaking, thus achieving rapid screening and discharge. This ensures the particle size of the microbial agent after wall breaking, prevents damage to microorganisms caused by excessive wall breaking, and improves the efficiency and quality of mixing between microbial agent and seed dressing agent. During the flipping process, the rolling roller 6 descends again to squeeze, acting on the outer wall of the air bladder 8. The air bladder 8 squeezes the squeezing bladder 39 that penetrates the intermediate float 38, so as to squeeze out and discharge the microbial agent in the positioning ring 41.

[0048] In a further design, a feed inlet 9 is provided on the side wall of the mixing tank 1, and a conical guide cone 10 is vertically arranged in the middle of the lower end of the mixing tank 1. The tilting plate 2 is located directly above the guide cone 10, and the lower outer wall of the guide cone 10 extends directly above the mixing tank 16. By setting the guide cone 10, the screened microbial agent is accurately dropped into the mixing tank 16, and the seed agent is fed through the feed inlet 9.

[0049] In a further design, the stirring motor 13 is installed at the lower end of the guide cone block 10. A right-angle connecting rod 15 is fixedly sleeved on the output shaft of the stirring motor 13. The other end of the right-angle connecting rod 15 is connected to the stirring disc 12 located in the stirring trough 16. The lower end of the stirring disc 12 is provided with multiple sets of stirring rods 11 arranged in a circumferential array. A ring-shaped gear ring 14 is provided on the inner side wall of the stirring trough 16. The middle bearing of the stirring disc 12 rotatably mounts the lower turntable 44. The upper end of the stirring rod 11 is vertically fixed to the lower end face of the lower turntable 44. The upper end of the lower turntable 44 extends to the upper end face of the stirring disc 12 and is fixedly connected to the upper turntable 42. The upper end bearing of the upper turntable 42 is rotatably connected to one end of the right-angle connecting rod 15. A linkage gear 45 is fixedly sleeved in the middle of the upper turntable 42. A driven gear 43 that meshes with the linkage gear 45 is vertically arranged on the side of the upper turntable 42 near the stirring motor 13. The driven gear 43 meshes with the gear ring 14.

[0050] By utilizing the cooperation of the upper turntable 42 and the lower turntable 44, the connection with the right-angle connecting rod 15 is achieved. Then, the stirring motor 13 drives the stirring plate 12 to rotate, so that the stirring rod 11 rotates in the stirring trough 16. While rotating in the circumference of the stirring trough 16, the gear linkage structure is set to drive the stirring rod 11 to rotate along the lower end of the stirring plate 12, which further improves the stirring efficiency and achieves full mixing of microbial inoculant and seed dressing agent.

[0051] In a further design, a tilting motor 3 is installed on the middle side wall of the mixing tank 1, and rotating rods 22 are installed at both ends of the tilting plate 2. One rotating rod 22 is rotatably mounted on the side wall of the mixing tank 1 with a bearing, and the other rotating rod 22 is connected to the output shaft of the tilting motor 3 through a flange plate. Through the cooperation of the tilting motor 3 and the rotating rod 22, the purpose of tilting and discharging materials is achieved.

[0052] In a further design, a second pad 33 is provided between the upper insert 30 and the lower insert 29. A rotating shaft 34 for rotatable bearing installation is provided at the upper end of the second pad 33. A semi-circular cross-section pressure groove 40 is provided through the middle of the lower end face of the intermediate float 38. The pressure groove 40 is pressed against the upper outer wall of the rotating shaft 34. The lower end face of the intermediate float 38 is attached to the upper end face of the air bladder 8 on both sides. By setting the cooperation between the rotating shaft 34 and the pressure groove 40, the intermediate float 38 can be rotatably installed. Then, during the extrusion process of the crushing roller 6, the crushing roller 6 is pressed against the upper end of one side of the intermediate float 38. Through the rotation of the intermediate float 38, the air bladder 8 is pressed, causing the other side of the air bladder 8 to expand and pull the other side of the intermediate float 38 to rotate and rise. This buffers the extrusion pressure and prevents the microbial agent from being tightly pressed between the intermediate float 38 and the wall-breaking plate 18, which would cause difficulty in material discharge and excessive extrusion that could cause the microbial agent to ignite. A gap for movement is left.

[0053] Further design features a first pad 32 at the lower end of the lower insert layer 29, and recessed slots 36 at the upper and lower ends of the airbag 8. The upper and lower slots 36 respectively engage with the first pad 32 and the second pad 33. Multiple sets of elongated grooves 20 are provided through the middle float plate 38. A limiting rod 37 is vertically fixed at the upper end of the airbag 8 and is vertically inserted into the elongated groove 20. By setting the pad and the slot 36, the installation position of the airbag 8 is limited, and the airbag 8 is supported and installed. The limiting rod 37 and the elongated groove 20 are used to limit the position of the airbag 8. After the airbag 8 is deformed by pressure, it is easy to cause positional displacement. The elongated groove 20 is used to allow the limiting rod 37 to shift position after the airbag 8 is deformed. At the same time, the position of the limiting rod 37 is prevented from excessive displacement and falling off.

[0054] Further design features two symmetrical sets of rotating connecting rods 23. The thickness of the intermediate float 38 is less than the interlayer height of the upper insert 30. An end plate 28 is provided at the end of the upper insert 30, with a pair of through holes 31 through the end plate 28, the inner diameter of which is larger than the outer diameter of the rotating connecting rod 23. The middle section of the rotating connecting rod 23 extends through the through holes 31 to the outside of the flip plate 2. By setting the end plate 28 and the through holes 31, the rotating connecting rod 23 can be conveniently extended through, thereby limiting the rotation amplitude of the intermediate float 38 and preventing excessive deviation.

[0055] Further design features a limiting frame 46 at the telescopic end of the telescopic hydraulic cylinder 27. The limiting frame 46 is designed as a right-angled plate, with the column 24 vertically fixed to the lower horizontal plate of the limiting frame 46. The outer ends of a pair of rotating connecting rods 23 are fixedly connected by a connecting plate 25. The connecting plate 25 has a compression groove 26 in the middle that fits the arc-shaped outer wall of the column 24. After flipping, the connecting plate 25 is located between the vertical plate of the limiting frame 46 and the column 24. A spring is sleeved on the outer wall of the other end of the rotating connecting rod 23. The spring is pressed between the intermediate float 38 and the end plate 28. By designing the limiting frame as a right-angled plate, the connecting plate 25 fits the outer wall of the column 24 after flipping. Driven by the telescopic hydraulic cylinder 27, the intermediate float 38 slides outward. The spring enables the intermediate float 38 to automatically reset, thereby achieving reciprocating telescopic sliding, compressing the microbial agent, and achieving the purpose of vibrating material discharge.

[0056] In a further design, a gantry frame 4 is provided at the upper end of the mixing tank 1, and a dual-axis displacement drive assembly is installed on the gantry frame 4. The dual-axis displacement drive assembly includes a transverse sliding block 7 for transverse sliding drive, and a vertically extending lifting drive assembly 5 is provided on the transverse sliding block 7. A rotating frame is provided at the lower end of the lifting drive assembly 5, and the crushing roller 6 is rotatably installed on the rotating frame. A pair of positioning grooves 17 are provided on the upper end surface of the flipping plate 2, and the lower end of the rotating frame is slidably installed in the positioning grooves 17. By setting the gantry frame 4 and the dual-axis displacement drive assembly, the longitudinal extension and retraction adjustment and transverse crushing drive of the crushing roller 6 are realized.
