Description

Technical Field

[0001] This utility model belongs to the field of screening equipment technology, specifically a screening device for compound fertilizer processing. Background Technology

[0002] In the production and processing of compound fertilizer, it is necessary to screen the particle size of the compound fertilizer. This means that the compound fertilizer with larger particles needs to be re-rolled and processed. At this time, screening equipment is needed to assist in the screening of the compound fertilizer.

[0003] Existing screening equipment has a relatively complete structure and function, which can meet basic usage requirements, but it still has the following problems:

[0004] In practical use, the filter screen is usually tilted for screening, so that the compound fertilizer particles are screened as they roll down the screen due to gravity. However, this screening method cannot guarantee thorough screening. Due to the falling speed or collision between particles, the screened compound fertilizer particles may still be mixed in size, requiring repeated screening, which is very inconvenient. Utility Model Content

However, this screening method cannot guarantee thorough screening. That is, due to the falling speed being too fast or the collision between particles, the screened compound fertilizer particles may still be mixed in size, which requires repeated screening and is very inconvenient.

Detailed Implementation

[0026] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0027] like Figure 1-5 As shown, this utility model provides a technical solution: a screening device for compound fertilizer processing, including a U-shaped frame 1, with a swing screening structure 2 inside the U-shaped frame 1. The swing screening structure 2 includes a swing frame 210, which can swing to screen the compound fertilizer particles inside. A screening mesh 212 is fixedly connected to the inner wall of the swing frame 210, which can assist in screening the compound fertilizer. Support blocks 211 are symmetrically fixedly connected to the bottom of the outer surface of the swing frame 210. The support block 211 can be used for auxiliary support after the swing frame 210 is disassembled. An auxiliary sealing structure 3 is provided on one side of the swing frame 210. The auxiliary sealing structure 3 includes a discharge hole 36 and a cover plate 34. The discharge hole 36 can discharge compound fertilizer granules. A sealing rectangular ring block 35 is fixedly connected to one side of the outer surface of the cover plate 34. The sealing rectangular ring block 35 can block the discharge hole 36. The discharge hole 36 is located on one side of the swing frame 210, and the screening screen 212 is located in the middle of the discharge hole 36.

[0028] Specifically, such as Figure 2 , Figure 3 and Figure 5As shown, a first motor 21 is fixedly installed on one side of the outer surface of the U-shaped frame 1. A rotating rod 22 is fixedly connected to the output end of the first motor 21. A rotating block 23 is fixedly connected to the outer surface of the rotating rod 22. The first motor 21 can drive the rotating rod 22 and the rotating block 23 to rotate, thereby cooperating with the swing frame 210 to perform swing screening. A rectangular clamping frame 24 is fixedly connected to the outer surface of the rotating block 23. A rectangular clamping block 25 is fixedly connected to the bottom of the outer surface of the swing frame 210. The rectangular clamping block 25 can interact with the rectangular clamping frame 24. 4. The rectangular clip 25 is engaged with the inner wall of the rectangular frame 24 for easy assembly and disassembly. The inner wall of the rectangular frame 24 has a first insertion hole 26 and the inner wall of the rectangular clip 25 has a second insertion hole 27. A threaded rod 28 is inserted into the inner wall of the first insertion hole 26 and the second insertion hole 27. The threaded rod 28 can be used to assemble and disassemble the rectangular clip 25 and the rectangular frame 24 by engaging with the first insertion hole 26 and the second insertion hole 27. A fixing nut 29 is threaded to one end of the outer surface of the threaded rod 28.

[0029] Specifically, such as Figure 4 As shown, a U-shaped plate 31 is fixedly connected to one side of the outer surface of the swing frame 210. A second motor 32 is fixedly installed on the top of the outer surface of the U-shaped plate 31. A transmission rod 37 is fixedly connected to the output end of the second motor 32. The transmission rod 37 can drive the auxiliary rotating block 33 to rotate, and thus can move in coordination with other components. An auxiliary rotating block 33 is fixedly connected to the outer surface of the transmission rod 37. The outer surface of the auxiliary rotating block 33 is fixedly connected to one side of the outer surface of the cover plate 34.

[0030] The working principle of this utility model is as follows:

[0031] S1. When in use, the rectangular card block 25 is fixed to the rectangular card frame 24. The threaded rod 28 is then inserted into the first insertion hole 26 and the second insertion hole 27, thereby fixing the fixing nut 29 to the threaded rod 28.

[0032] S2. At this time, the first motor 21 is started, so that the first motor 21 can drive the rotating rod 22 and the rotating block 23 to rotate, which in turn can drive the swing frame 210 to rotate, which can then cooperate with the screening screen 212 for auxiliary screening.

[0033] S3. After screening, the second motor 32 is started, which allows the auxiliary rotating block 33 to drive the cover plate 34 to rotate, thereby driving the sealing rectangular ring block 35 to separate from the discharge hole 36, and thus discharging the compound fertilizer granules inside the swing frame 210.
