Description

Technical Field

[0001] This utility model relates to the field of screening machine technology, and in particular to a compound fertilizer drum screening machine. Background Technology

[0002] In existing technology, the raw material screening process is as follows: the raw material is conveyed from the feed hopper into the screening cylinder. A motor, as the power source, drives the rotating shaft and rotating sleeve to rotate via a combination of transmission belt and spur gears. Furthermore, the design intentionally places the rotating shaft and rotating sleeve in opposite directions. This reverse rotation allows the rotating shaft and its connected rotating rod to drive a paddle to move the raw material in a specific manner, thereby achieving the screening operation.

[0003] However, in actual operation, the air contains a large amount of moisture, which is easily absorbed by the raw materials of compound fertilizer. Once the raw materials absorb a certain amount of moisture, clumping may occur during the screening process or subsequent stages. To address this, existing technology involves collecting the clumped material separated during screening, breaking it up to initially disperse the clumps, and then crushing it into smaller particles to meet production requirements. However, this method has significant drawbacks. From an operational perspective, it requires multiple steps sequentially, making the process cumbersome and increasing both the difficulty and time cost of manual operation. Therefore, a compound fertilizer drum screening machine is needed to solve these problems. Utility Model Content

[0005] The technical solution of this utility model is as follows: a compound fertilizer drum screener, including a base plate; it also includes a motor and a grading and discharge assembly. A support frame is fixedly connected to the bottom of the base plate, a motor is fixedly connected to the outside of the base plate, and a discharge assembly is provided at the bottom of the base plate. A gear is fixedly connected to the output end of the motor, which drives the gear to rotate. A gear ring meshes with the outside of the gear. A drum screen is fixedly connected to the outside of the gear ring. A spiral baffle is fixedly connected to the inside of the drum screen. A connecting cover is fixedly connected to the outside of the base plate. A dispersing box is fixedly connected to the outside of the connecting cover. A funnel is fixedly connected to the outside of the dispersing box. A second motor is fixedly connected to the outside of the dispersing box. A first dispersing plate is fixedly connected to the output end of the second motor. A first sprocket is fixedly connected to the outside of the first dispersing plate. A chain is driven to the outside of the first sprocket. A second sprocket is driven to the end of the chain away from the first sprocket. A second dispersing plate is fixedly connected to the outside of the second sprocket.

[0006] Preferably, the dispersing box has a through hole, and the dispersing plate is rotatably connected to the inside of the dispersing box through the through hole.

A grading and discharge port box is fixedly connected to the bottom of the grading plate, and an arc-shaped plate is fixedly connected to the top of the base plate.

[0012] The beneficial effects of this invention are as follows: After the second motor is started, it drives the first sprocket outside the first dispersing plate to rotate.

A support frame 4 is fixedly connected to the bottom of the base plate 1, and the motor 21 is fixedly connected to the outside of the base plate 1. A discharge assembly is provided at the bottom of the base plate 1. A gear 22 is fixedly connected to the output end of the motor 21, and the motor 21 drives the gear 22 to rotate. A gear ring 23 meshes with the outside of the gear 22. A drum screen 24 is fixedly connected to the outside of the gear ring 23. A spiral baffle 25 is fixedly connected to the inside of the drum screen 24. A connecting cover 26 is fixedly connected to the outside of the base plate 1, and a dispersing box 27 is fixedly connected to the outside of the connecting cover 26. A funnel 28 is fixedly connected to the outside of the dispersing box 27. A second motor 29 is also fixedly connected to the outside of the dispersing box 27. A first dispersing plate 210 is fixedly connected to the output end of the second motor 29. A first sprocket 211 is fixedly connected to the outside of the first dispersing plate 210. A chain 212 is driven by the outside of the first sprocket 211. A second sprocket 213 is driven by the end of the chain 212 away from the first sprocket 211. A second dispersing plate 214 is fixedly connected to the outside of the second sprocket 213. When the compound fertilizer to be screened is poured into the dispersing box 27 through the funnel 28, the second motor 29 will drive the first sprocket 211 outside the first dispersing plate 210 to rotate. The first sprocket 211 will drive the chain 212 to rotate by the second sprocket 214. The external rotation of 3 causes the sprocket 213 to drive the dispersing plate 214 and the dispersing plate 210 to rotate simultaneously, so that the sprocket 213 and the dispersing plate 214 dissolve the clumps of compound fertilizer. The dissolved compound fertilizer falls into the inside of the drum screen 24. The motor 21 drives the gear 22 to rotate, which in turn drives the drum screen 24 outside the gear ring 23 to rotate. At the same time, the spiral baffle 25 inside the drum screen 24 simultaneously filters the compound fertilizer. The dispersing box 27 has a through hole 1, and the dispersing plate 210 is rotatably connected to the inside of the dispersing box 27 through the through hole 1. The dispersing box 27 is provided to facilitate the foundation of other components. The connecting cover 26 has a... There is a rotating groove 1, through which the drum screen 24 is rotatably connected to the inside of the connecting cover 26. The connecting cover 26 facilitates the connection between the dispersing box 27 and the drum screen 24. A rotating groove 2 is provided on the base plate 1, through which the drum screen 24 is rotatably connected to the inside of the base plate 1. The base plate 1 provides a foundation for other components. The holes on the drum screen 24 gradually decrease in size from left to right. The drum screen 24 facilitates the screening of compound fertilizer. When the first sprocket 211 rotates, the chain 212 will drive the second sprocket 213 to rotate simultaneously. The first sprocket 211 facilitates the rotation of the second sprocket 213 via the chain 212.

[0021] Please see Figure 5 In this embodiment, the grading and discharging assembly includes a grading plate 31, which is fixedly connected to the bottom of the base plate 1. A grading and discharging port box 32 is fixedly connected to the bottom of the grading plate 31, and an arc-shaped plate 33 is fixedly connected to the top of the base plate 1. The grading plate 31 facilitates the separation of coarse and fine compound fertilizers by coarse and fine discharging in conjunction with the grading and discharging port box 32.

[0022] During operation, the compound fertilizer to be screened is poured into the dispersing box 27 through the funnel 28. At this time, the motor 29 drives the sprocket 211 outside the dispersing plate 210 to rotate. The sprocket 211 drives the chain 212 to rotate outside the sprocket 213, so that the sprocket 213 drives the dispersing plate 214 and the dispersing plate 210 to rotate simultaneously. The sprocket 213 and the dispersing plate 214 dissolve the clumps of compound fertilizer. The dissolved compound fertilizer falls into the drum screen 24. The motor 21 drives the gear 22 to rotate, so that the gear 22 drives the drum screen 24 outside the gear ring 23 to rotate. At the same time, the spiral baffle 25 inside the drum screen 24 simultaneously screens the compound fertilizer. The screened compound fertilizer is discharged through the grading outlet box 32 at the bottom of the grading plate 31.

[0023] Through the above steps, the optimized text is as follows: After motor 29 starts, it drives the sprocket 211 outside the dispersing plate 210 to rotate. Sprocket 211 drives sprocket 213 to rotate synchronously via chain 212. The rotation of sprocket 213 drives dispersing plate 214 to operate together with dispersing plate 210, and the synergistic effect of the two plates breaks up the clumps of compound fertilizer. This design simplifies the operation process, requiring only a single motor to drive the two plates, effectively reducing equipment complexity and production costs.
