Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizer particle screening, in particular to a compound fertilizer particle vibrating screen device. Background Art

[0002] Compound fertilizer refers to a fertilizer containing nitrogen, phosphorus and potassium or two or more nutrient elements, which has the advantages of high nutrient content, few by-products and good physical properties. Compound fertilizer is of great significance for balanced fertilization, improving fertilizer utilization and promoting high and stable yield of crops.

[0003] Since compound fertilizer is made by mixing multiple raw materials and then granulating into granules, the particle size is uneven. Since the particle size of compound fertilizer needs to be unified within a certain range before leaving the factory, the compound fertilizer needs to be screened to make the particles uniform and packaged.

[0004] The existing screening equipment mainly adopts the vibration screening method, placing the compound fertilizer particles on the vibrating screen, and shaking the vibrating screen so that the smaller compound fertilizer particles fall from the screen holes of the vibrating screen, and the larger compound fertilizer particles remain on the vibrating screen to achieve screening.

[0005] Although the above screening equipment screens the compound fertilizer particles into two parts during screening, the separated compound fertilizer particles of two sizes still need to be taken out and packaged later, which is inefficient. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a compound fertilizer particle vibrating screen device, which solves the problem that particles need to be taken out manually or by other tools after screening, resulting in low efficiency.

[0007] To achieve the above purpose, the utility model is implemented through the following technical solutions: a compound fertilizer particle vibration screen device, comprising:

[0008] A hollow frame with an upper opening, wherein the frame is set in an inclined shape with the left side higher and the right side lower;

[0009] A discharge port, the discharge port is opened on the inner right side of the frame, a support plate is provided on the inner right side of the frame, and the support plate is located on the right side of the discharge port;

[0010] A rotating shaft, the rotating shaft is rotatably connected to the inner left side of the frame, one end of the rotating shaft extends to the outside of the frame, and a driving motor connected to the rotating shaft is arranged on the outer wall of the frame, and a cam is sleeved on a section of the outer wall of the rotating shaft located inside the frame;

[0011] The sieve plate is located in the frame, one end of the sieve plate extends to the inner left side of the frame, and the other end of the sieve plate extends to the right outer side of the frame. The lower surface of the sieve plate is supported on the cam and the support plate.

[0012] Preferably, a fine material receiving box and a coarse material receiving box are respectively provided on the lower right side of the frame and the right side of the frame, the fine material receiving box is located directly below the discharge port, and the coarse material receiving box is located on the lower right side of the screen plate.

[0013] Preferably, a guide plate is provided on the upper left side of the interior of the frame, the guide plate is inclined with the left side higher than the right side, and the right end of the guide plate is located on the upper side of the left end of the screen plate.

[0014] Preferably, an elastic member is connected between the left upper surface of the sieve plate and the right lower surface of the guide plate.

[0015] Preferably, a support shaft is provided on the upper surface of the support plate, and the support shaft is connected to the lower surface of the sieve plate via a rotating support mechanism.

[0016] Preferably, the rotation support mechanism includes a bearing rotatably connected to the outer wall of the support shaft, a bearing seat connected to the outer wall of the bearing, and a support column connected to the upper end of the bearing seat, and the top end of the support column is connected to the lower surface of the screen plate.

[0017] The utility model provides a compound fertilizer particle vibrating screen device, which has at least the following beneficial effects compared with the prior art:

[0018] The frame is set to be inclined, and the screen plate inside the frame is also inclined. When screening, the granular material moves to the lower end of the screen plate under the action of gravity, thus avoiding material accumulation. Facing the movement of the material, the higher end of the screen plate is idle, so that material can continue to be added, so that screening can be carried out continuously and the screening efficiency is high.

[0019] After the granular materials are screened, the larger sized granular materials move directly from the upper side to the lower side, and can be caught by the coarse material receiving box from the lower side. The smaller sized granular materials move out from the discharge port and enter the fine material receiving box. At this time, the support plate can support the screen plate and block the smaller sized granular materials at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The compound fertilizer particle vibration screen device provided by the utility model comprises: a hollow frame 1 with an upper opening, a discharge port 2, a rotating shaft 12 and a screen plate 8;

[0028] The frame 1 is set to be inclined with the left side higher and the right side lower. The discharge port 2 is opened on the inner right side of the frame 1. A support plate 3 is provided on the inner right side of the frame 1. The support plate 3 is located on the right side of the discharge port 2. The rotating shaft 12 is rotatably connected to the inner left side of the frame 1. One end of the rotating shaft 12 extends to the outside of the frame 1, and a driving motor 11 connected to the rotating shaft 12 is provided on the outer wall of the frame 1. A cam 13 is sleeved on a section of the outer wall of the rotating shaft 12 located in the frame 1. The sieve plate 8 is located in the frame 1, one end of the sieve plate 8 extends to the inner left side of the frame 1, and the other end of the sieve plate 8 extends to the right outer side of the frame 1. The lower surface of the sieve plate 8 is supported on the cam 13 and the support plate 3.

[0029] When in use, the compound fertilizer is placed on the upper left side of the sieve plate 8 (this solution can also be used for other granular materials, as long as the sieve plate 8 with a suitable aperture is selected). Under the action of gravity, the compound fertilizer rolls to the lower right side. At the same time, the drive motor 11 drives the rotating shaft 12 and the cam 13 to rotate, and the cam 13 reciprocates, so that the sieve plate 8 is subjected to reciprocating impact to achieve vibration. Under the vibration of the sieve plate 8, the compound fertilizer particles with a particle size smaller than the sieve hole fall, and the particles with a particle size larger than the sieve hole remain on the sieve plate 8. In this way, the compound fertilizer particles of different particle sizes are separated.

[0030] See also Figure 1-5A fine material receiving box 9 and a coarse material receiving box 10 are respectively provided on the lower right side of the frame 1 and the right side of the frame 1. The fine material receiving box 9 is located directly below the discharge port 2, and the coarse material receiving box 10 is located on the lower right side of the screen plate 8.

[0031] When in use, the fine material collecting box 9 and the coarse material collecting box 10 can collect the compound fertilizer particles with a particle size smaller than the sieve holes and the compound fertilizer particles with a particle size larger than the sieve holes, respectively.

[0032] See also Figure 1-5 A guide plate 14 is provided on the upper left side of the frame 1. The guide plate 14 is inclined with the left side higher than the right side. The right end of the guide plate 14 is located on the upper side of the left end of the sieve plate 8. An elastic member 15 is connected between the upper surface of the left end of the sieve plate 8 and the lower surface of the right end of the guide plate 14.

[0033] Since the sieve plate 8 needs to vibrate, there is a gap between the left end of the sieve plate 8 and the inner wall of the frame 1. The guide plate 14 is provided to cover the gap to prevent compound fertilizer from being stuck in the gap. When compound fertilizer is added to the frame 1, the guide plate 14 guides it onto the sieve plate 8. The elastic member 15 is provided to elastically press the sieve plate 8 when the sieve plate 8 vibrates to prevent the sieve plate from vibrating and bouncing too high.

[0034] See also Figure 1-5 A support shaft 4 is provided on the upper surface of the support plate 3, and the support shaft 4 is connected to the lower surface of the sieve plate 8 through a rotating support mechanism. The rotating support mechanism includes a bearing 6 rotatably connected to the outer wall of the support shaft 4, a bearing seat 5 connected to the outer wall of the bearing 6 and a support column 7 connected to the upper end of the bearing seat 5, and the top end of the support column 7 is connected to the lower surface of the sieve plate 8.

[0035] The sieve plate 8 is supported on the bearing 6 through the support column 7 and the bearing seat 5. The bearing can rotate relative to the support shaft 4, so that the sieve plate 8 can be stably supported.
