Technical Field

[0001] The utility model relates to the technical field of fertilizer processing, in particular to a vibrating screen for fertilizer processing. Background Art

[0002] Compound fertilizer refers to inorganic fertilizer containing two or more nutrients such as nitrogen, phosphorus and potassium. Its main functions include improving soil fertility, promoting crop growth, increasing crop yields and improving the quality of agricultural products.

[0003] The screens in the existing vibrating screens are mostly detachable and arranged in the screen box, and the existing compound fertilizers are mostly powdered or granular. However, due to the different formulas of different types of compound fertilizers, the particle sizes will also vary, and the screening requirements will also be different. After using the vibrating screen for screening for a period of time, or when changing to a new fertilizer formula, it is necessary to first remove the original screen and then replace the corresponding screen to adapt to the screening. In this way, the screen will need to be frequently disassembled and replaced. For this reason, a vibrating screen for fertilizer processing is proposed. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] like Figure 1 and Figure 2 As shown, a vibrating screen for fertilizer processing in this embodiment is mainly used for processing compound fertilizers, including a screen box 1, a screen belt 2 and a driving assembly 3, wherein a fertilizer inlet is arranged at the top of the screen box 1, and the horizontal height of the screen belt 2 is lower than the horizontal height of the inlet, so that the fertilizer entering from the inlet can fall onto the screen belt 2, and the screen box 1 has a screening space, and a part of the screen belt 2 is located in the screening space, and a plurality of screening holes 21 are arranged on the screen belt 2, and another portion of the screen belt 2 is provided with a plurality of screening holes 21. Part is located outside the screen box 1, where a plurality of screen holes 22 are arranged on the screen belt 2. When the screen hole 1 21 is located in the screen space, the screen hole 1 21 performs the screening work on the compound fertilizer. When the screen hole 22 is located in the screen space, the screen hole 22 performs the screening work on the compound fertilizer. The driving component 3 is used to drive the screen belt 2 for belt transmission, so that the screen hole 1 21 can be located outside the screen box 1, and the screen hole 22 can be located in the screen box 1.

[0028] It should be noted that the portion of the screen belt 2 located in the screen box 1 is inclined so that the fertilizer can slide along the screen belt 2 to the discharge port 11 .

[0029] Further explanation, such as Figure 3 and 4 As shown, the left side of the screening belt 2 is located at the discharge port 11 of the screen box 1 , and the other side thereof extends from the expansion port 12 and to the tail of the expansion frame 13 .

[0030] And as Figure 1 As shown, a discharge port 11 is arranged on the left side of the screen box 1, and the number of the discharge ports 11 depends on the number of the driving components 3, which is used to discharge the screened compound fertilizer. An expansion port 12 is arranged on the side of the screen box 1 away from the discharge port 11, and an expansion frame 13 is welded thereon. The expansion frame 13 is composed of two groups of expansion plates, and the two groups of expansion plates are welded to the right side of the screen box 1, and the screen belt 2 located on the outside of the screen box 1 is located between the two groups of expansion plates.

[0031] As for the drive component 3, Figure 1-3As shown, the driving assembly 3 includes a driving component 31 and a plurality of transmission shafts 32. The screening belt 2 is located on the outside of the plurality of transmission shafts 32. Any group of transmission shafts 32 is connected to the driving component 31. When the driving component 31 is working, the transmission is transmitted through the transmission shafts 32, so that the screening belt 2 is driven.

[0032] It should be noted that the driving component 31 is a motor, which is used to drive the transmission shaft 32 to work, and then the screening belt 2 is driven. It can be understood that the output end of the motor can also be equipped with a reducer, so that the reduction end of the reducer can be connected to any group of transmission shafts 32. There is no existing technology for the motor to be equipped with a reducer, so it will not be elaborated here. The reducer is not shown.

[0033] It should also be noted that if Figure 1 and 2 As shown, the fertilizer processing vibration screen also includes a base, which is located below the screen box 1, and a support bar is welded on the base, and a vibration isolation spring and a damper are installed between the support bar and the screen box 1. Figure 3 As shown, a vibrator is fixed to the bottom of the screen box 1 by bolts. The vibrator, vibration isolation spring and damper are prior arts in the art and will not be described in detail here.

[0034] In addition, the number of screening belts 2 is the same as the number of driving assemblies 3, and the number of screening belts 2 is not less than one group. In the present embodiment, the preferred scheme is that the number of screening belts 2 is two groups, and the two groups of screening belts 2 are distributed up and down, and the diameters of screening hole 1 21 and screening hole 2 22 on the lower screening belt 2 are both smaller than the diameters of screening hole 1 21 or screening hole 2 22 on the upper screening belt 2, thereby forming two screenings.

[0035] As the focus of the present application, the sieve hole 1 21 and the sieve hole 2 22 on the sieve belt 2 will produce different effects if their diameters are the same or different, which will be explained here.

[0036] In one embodiment, the diameters of the first screen hole 21 and the second screen hole 22 are different to change the screening of the fertilizer particle size.

[0037] During use, when a new compound fertilizer formula is changed, the motor is started and the transmission is transmitted through the transmission shaft 32 to allow the screen belt 2 to be driven. In this way, the screen hole 1 21 initially located in the screen box 1 will be located on the outside of the screen box 1, and the screen hole 2 22 initially located on the outside of the screen box 1 will be located in the screen box 1. After the screen hole 1 21 and the screen hole 2 22 are switched in place, since the position of the screen hole 22 is switched with the screen hole 1 21, and the diameters of the screen hole 1 21 and the screen hole 2 22 are different, it will be possible to cope with the screening of another compound fertilizer formula.

[0038] It can be understood that, in another embodiment, the diameters of screen hole 1 21 and screen hole 2 22 can also be the same, so that screen hole 1 21 and screen hole 2 22 can work alternately, and in some continuous screening operations, the fertilizer processing vibrating screen can continue to screen the compound fertilizer without stopping the machine.

[0039] During use, considering that some impurities may remain on the screen hole 21, when the screen hole 21 needs to be maintained or during continuous screening work, the motor can be started and the transmission can be transmitted through the transmission shaft 32 to allow the screen belt 2 to be driven. In this way, the screen hole 21 initially located in the screen box 1 will be located on the outside of the screen box 1, and the screen hole 22 initially located on the outside of the screen box 1 will be located in the screen box 1. After the screen hole 21 and the screen hole 22 are switched into place, when maintenance is needed later, the workers can directly maintain the screen hole 21 on the outside of the screen box 1. Since there is no need to disassemble the screen belt 2, the inconvenience of disassembly and assembly is eliminated, the burden on workers is reduced, and the maintenance of the screen belt 2 can be facilitated.

[0040] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
