Description

Technical Field

[0001] This utility model relates to the technical field of microbial agent screening equipment, and in particular to a screening device for the production of microbial agents. Background Technology

[0002] Microbial inoculants are a class of live preparations made from beneficial microorganisms and their metabolites, widely used in agriculture, environmental protection, and other fields. They can be divided into three main categories: liquid, solid, and semi-solid. Among them, the solid form is currently the most widely used in agriculture and the environment, accounting for over 70%. Its core process is to "reduce the moisture content of the inoculant stock solution through drying, allowing the live bacteria to survive in the form of spores or dormant cells." After drying, the inoculant raw material will be in the form of granules or powder of different particle sizes.

[0003] Currently, dried raw materials are usually screened to ensure uniform particle size of the microbial agent, thus guaranteeing uniformity during actual application. To improve production efficiency, screening equipment is generally used to screen the microbial agent raw materials. For example, Chinese utility model patent CN221108935U discloses a screening mechanism for microbial agents. This mechanism is equipped with a screening tank, inside which a horizontally placed screening frame is installed. A sliding rod is vertically installed at the bottom of the screening frame, which is connected to the tank. A spring is fitted on the sliding rod. During operation, the microbial agent raw material is conveyed from the top of the tank to the top of the screening frame, and then a vibrating motor drives the screening frame to vibrate, thereby achieving the screening of the microbial agent raw material.

[0004] However, in actual operation, due to the horizontal setting of its screening rack, the unscreened bacterial agent material cannot be actively discharged. The more the bacterial agent material that does not pass through the screening rack accumulates, the more the screening rack vibrates, causing the bacterial agent material to splash and the screening effect to be poor. If the machine is stopped for cleaning, the overall operating efficiency will decrease. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a screening device for the production of microbial agents, which solves the problems of poor screening effect and reduced operating efficiency caused by the accumulation of microbial agent raw materials on the screening rack in existing technologies.

[0006] According to an embodiment of this utility model, a screening device for producing microbial agents includes a cylinder, a screening component, a swinging component, a first motor, a feeding auger, and a second motor. The cylinder is a hollow cylinder arranged horizontally with an open bottom. The cylinder is provided with an inlet and a outlet. The screening component is slidably disposed at the bottom opening of the cylinder and is used to screen the raw materials for the microbial agent. The swinging component is disposed on the end side of the cylinder and connected to the end side of the screening component. The first motor is disposed on the outside of the cylinder and is used to drive the swinging component to drive the screening component to reciprocate. The feeding auger is coaxially disposed inside the cylinder and is used to push the raw materials for the microbial agent to one side. The second motor is disposed on the side of the cylinder away from the first motor and is used to drive the feeding auger to rotate.

[0007] In the above embodiments, the raw material of the microbial agent to be screened is injected into the cylinder, and the first motor is started. The first motor drives the swinging component to swing back and forth, which in turn drives the screening component to swing together. This causes the screening component to swing back and forth at the bottom of the cylinder, thereby screening the raw material of the microbial agent and effectively reducing the splashing of raw material during the screening process. Furthermore, the second motor is started, which drives the feeding auger in the cylinder. The feeding auger pushes the raw material of the microbial agent to one side of the cylinder, effectively avoiding the accumulation of the raw material of the microbial agent.

[0008] In some embodiments, the screening component includes an arc-shaped frame that is slidably connected to an opening at the bottom of the cylinder and a screen mounted on the frame. One end of the frame extends through to the outside of the end side of the cylinder and is connected to the swinging component.

[0009] In some embodiments, the radius of curvature of the skeleton cross section is the same as the radius of the cylinder, and the coverage area of ​​the skeleton is larger than the opening area of ​​the cylinder.

[0010] In some embodiments, the swing member includes a swing rod rotatably disposed at the center of one end of the cylinder and a connecting frame installed at the bottom end of the swing rod and fixedly connected to the end side of the skeleton. A rotating wheel connected to the first driving member is provided on one side of the swing rod, a sliding hole is provided at the top of one side of the swing rod, and a knob adapted to the sliding hole is provided on one side of the rotating wheel.

[0011] In some embodiments, a rotating shaft is coaxially rotatably arranged inside the cylinder, and a plurality of stirring rods are evenly distributed on the outside of the rotating shaft. One end of the rotating shaft is connected to a sprocket assembly for external transmission with the output shaft of the first motor.

[0012] In some embodiments, the feeding auger is rotatably disposed within the cylinder, a flapping plate is provided within the threaded gap of the feeding auger, and the outer edge of the feeding auger contacts the inner wall of the cylinder.

[0013] In some embodiments, a rotating sleeve is fixedly connected to one end of the feeding auger, and gears are fixedly installed on one end of the output shaft of the second motor and one end of the rotating sleeve, with the two gears meshing with each other.

[0014] Compared with the prior art, this utility model has the following beneficial effects: by adopting the method of using a swinging component to drive the screening component to swing back and forth and cooperating with the feeding auger to push the material to one side, it solves the technical problem of poor screening effect and reduced operation efficiency caused by the accumulation of bacterial agent raw materials on the screening frame in the existing screening device, thereby achieving the technical effect of improving screening effect and screening efficiency.

Detailed Implementation

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] In an exemplary implementation, such as Figures 1-6 As shown, this embodiment provides a screening device for the production of microbial agents, including a cylinder 100, a screening component 200, a swing component 300, a first motor 400, a feeding auger 500, and a second motor 600. The cylinder 100 is a hollow cylinder arranged horizontally with an open bottom. The cylinder 100 is provided with an inlet 110 and a outlet 120. The screening component 200 is slidably disposed at the bottom opening of the cylinder 100 and is used to screen the raw materials of the microbial agent. The swing component 300 is disposed on the end side of the cylinder 100 and connected to the end side of the screening component 200. The first motor 400 is disposed on the outside of the cylinder 100 and is used to drive the swing component 300 to drive the screening component 200 to swing back and forth. The feeding auger 500 is coaxially disposed inside the cylinder 100 and is used to push the raw materials of the microbial agent to one side. The second motor 600 is disposed on the side of the cylinder 100 away from the first motor 400 and is used to drive the feeding auger 500 to rotate.

[0025] In this embodiment, the raw material of the microbial agent to be screened is injected into the cylinder 100, and the first motor 400 is started. The first motor 400 drives the swinging component 300 to swing back and forth. The swinging component 300 can drive the screening component 200 to swing back and forth at the bottom of the cylinder 100, thereby screening the raw material of the microbial agent and effectively reducing the splashing of raw material during the screening process. Furthermore, the second motor 600 is started. The second motor 600 can drive the feeding auger 500 in the cylinder 100. The feeding auger 500 pushes the raw material of the microbial agent to one side of the cylinder 100, effectively avoiding the accumulation of the raw material of the microbial agent.

[0026] In one embodiment, please refer to Figures 4-6 The screening component 200 includes an arc-shaped frame 210 that is slidably connected to the opening at the bottom of the cylinder 100 and a screen 220 mounted on the frame 210. One end of the frame 210 extends to the outside of the end side of the cylinder 100 and is connected to the swing component 300. The radius of curvature of the cross section of the frame 210 is the same as the radius of the cylinder 100, and the coverage area of ​​the frame 210 is larger than the opening area of ​​the cylinder 100.

[0027] In this embodiment, the frame 210 coincides with the center point of the cylinder 100. When the swinging component 300 drives the frame 210 to swing back and forth, the frame 210 and the screen 220 can swing in an arc trajectory at the bottom of the cylinder 100. Since the coverage area of ​​the frame 210 and the screen 220 is larger than the opening area of ​​the cylinder 100, the swinging of the frame 210 will not cause the raw material to leak directly out of the opening of the cylinder 100.

[0028] In one embodiment, please refer to Figures 1-2 The swinging component 300 includes a swinging rod 310 rotatably disposed at the center of one end of the cylinder 100 and a connecting frame 320 installed at the bottom end of the swinging rod 310 and fixedly connected to the end side of the frame 210. A rotating wheel 340 connected to the output shaft of the first motor 400 is provided on one side of the swinging rod 310. A sliding hole 330 is opened at the top of one side of the swinging rod 310, and a knob 350 adapted to the sliding hole 330 is provided on one side of the rotating wheel 340.

[0029] In this embodiment, the first motor 400 is started, which drives the rotating wheel 340 to rotate. The rotating wheel 340 drives the knob 350 to perform a circular motion. The knob 350 is eccentrically set on the rotating wheel 340, and the rotating wheel 340 is not limited in the length direction of the sliding hole 330. In other directions, it will drive the swing rod 310 to make a corresponding displacement, thereby driving the swing rod 310 to swing back and forth. This causes the swing rod 310 to drive the frame 210 and the screen 220 to swing back and forth together, thereby realizing screening.

[0030] Please refer to Figure 4 and Figure 5 A rotating shaft 130 is coaxially rotatable inside the cylinder 100. Several stirring rods 140 are evenly distributed on the outside of the rotating shaft 130. One end of the rotating shaft 130 is connected to a sprocket set 150 for external transmission to the output shaft of the first motor 400. The first motor 400 drives the rotating shaft 130 and the several stirring rods 140 on the outside to rotate through the sprocket set 150.

[0031] Among them, the sprocket assembly 150 is a conventional existing structure. If the two sprockets are fitted with the same chain, in this device, the rotation speed of the stirring rod 140 on the rotating shaft 130 can also be controlled by adjusting the diameter ratio of the two sprockets.

[0032] In one embodiment, please refer to Figures 4-6 The feeding auger 500 is rotatably installed inside the cylinder 100. A flapping plate 510 is provided in the threaded gap of the feeding auger 500. The outer edge of the feeding auger 500 is in contact with the inner wall of the cylinder 100. A rotating sleeve 520 is fixedly connected to one end of the feeding auger 500. Gears 530 are fixedly installed on one end of the output shaft of the second motor 600 and one end of the rotating sleeve 520, and the two gears 530 mesh with each other.

[0033] In this embodiment, the second motor 600 can drive the feeding auger 500 to rotate through the meshing gear 530, thereby pushing the bacterial agent raw material to one side to avoid accumulation and improve the screening effect.

[0034] The rotating sleeve 520 is rotatably mounted on the rotating shaft 130, meaning that the rotating shaft 130, the rotating sleeve 520, and the feeding auger 500 are all coaxially arranged with the cylinder 100.

[0035] Furthermore, the flipping plate 510 on the feeding auger 500 can stir the bacterial agent raw material on the screen 220, and the stirring rod 140 can break up the clumps or relatively large volumes of bacterial agent raw material.

[0036] Furthermore, a discharge guide plate 700 is provided at the bottom of the cylinder 100. The discharge guide plate 700 completely covers the opening of the cylinder 100 and is used to control the discharge position.

[0037] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail as follows: In use, the raw material of the microbial agent to be screened is injected into the cylinder 100 through the feed inlet 110. The first motor 400 is started, which drives the rotating wheel 340 to rotate. The rotating wheel 340 drives the knob 350 to make a circular motion. The knob 350 is eccentrically set on the rotating wheel 340. The rotating wheel 340 is not limited in the length direction of the sliding hole 330. In other directions, it will drive the swing rod 310 to make a corresponding displacement, thereby driving the swing rod 310 to swing back and forth. This causes the swing rod 310 to drive the frame 210 and the screen 220 to swing back and forth together to achieve screening. This effectively reduces the splashing of raw materials during the screening process. The raw material of the microbial agent that passes through the screen 220 is discharged through the discharge guide plate 700.

[0038] Furthermore, the second motor 600 is started, which drives the feeding auger 500 to rotate through the meshing gear 530. This pushes the bacterial agent raw material to one side until the bacterial agent raw material that cannot pass through the screen 220 is discharged from the discharge port 120, avoiding accumulation and improving the screening effect.

[0039] In summary, this utility model solves the technical problems of poor screening effect and reduced operating efficiency caused by the accumulation of bacterial agent raw materials on the screening frame in existing screening devices by using the swing component 300 to drive the screening component 200 to swing back and forth and cooperating with the feeding auger 500 to push the material to one side. This achieves the technical effect of improving screening effect and screening efficiency.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
