Description

Technical Field

[0001] This utility model relates to a fertilizer screening machine. Background Technology

[0002] A fertilizer screening machine, also known as a screening machine or vibrating screen, is a mechanical device specifically designed for screening and classifying fertilizers. It separates fertilizer raw materials according to particle size through vibration and the action of screens, achieving the purposes of classifying, grading, or removing impurities from fertilizers of different particle sizes. The working principle of a fertilizer screening machine is mainly based on the action of vibration and screens. The raw material first enters the screening machine through the feed inlet, and then, under the action of vibration, the raw material is evenly distributed onto each screen. Because raw material particles of different sizes are affected by different amplitudes and frequencies of vibration, they will be screened out on different screens. Finally, fertilizer particles that meet the requirements are discharged from the outlet, while particles that do not meet the requirements are retained on the screens for further screening.

[0003] Fertilizer screening machines are devices used for screening the quality of fertilizers. When using fertilizer screening machines, multiple screens are usually required to ensure the screening effect of fertilizers. However, this can cause frequent vibration of fertilizers, which can affect the particle size of fertilizers and reduce the processing quality of fertilizers. In addition, when too much fertilizer is transported, it is difficult for fertilizers to pass through the screens effectively, resulting in a reduction in screening effect and affecting subsequent production.

[0026] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0027] like Figure 1-3 As shown, the fertilizer screening machine includes:

[0028] The base plate 1 has a support 2 fixedly installed on its top. The support 2 is connected to the housing 3 through a rotating mechanism. A vertical plate 19 is fixedly installed on one side of the base plate 1, and a flattening mechanism located inside the housing 3 is fixedly installed on the top of the vertical plate 19.

[0029] The enclosure 11 is fixedly connected to the interior of the housing 3. A screen 12 for fertilizer screening is fixedly installed in the middle of the enclosure 11. A first discharge port 13 is opened on one side of the housing 3 located inside the enclosure 11, and a second discharge port 14 is opened on the other side of the housing 3 located outside the enclosure 11. A feeding mechanism is fixedly installed on one side of the housing 3.

[0030] In this technical solution, the top of the base plate 1 is provided with two ring-shaped supports 2, which are symmetrically distributed on both sides of the shell 3. The shell 3 is rotatably connected to the support 2. The support 2 is used for the rotation of the shell 3 and to achieve stable support for the shell 3.

[0031] In this technical solution, the rotating mechanism includes a rib 4, which is a ring-shaped mechanism and is fixedly connected to the surface of the housing 3. There are four ribs 4, and every two ribs 4 are located inside the support 2. The sidewall of the rib 4 is rotatably connected to several evenly distributed rollers 5, and the rollers 5 are in close contact with the inner wall of the support 2. The rollers 5 are installed through the ribs 4. When the housing 3 drives the ribs 4 to rotate, the rollers 5 always roll on the inner wall of the support 2.

[0032] In this technical solution, a side plate 6 is fixedly installed in the middle of the base plate 1. The side plate 6 is rotatably connected to the transmission gear 7 and the output gear 8 respectively. The transmission gear 7 is meshed with the output gear 8. The output gear 8 is fixedly connected to the output end of the drive motor 9. The drive motor 9 is fixedly installed on the top surface of the base plate 1. When the drive motor 9 is working, it drives the output gear 8 to rotate between the side plates 6, thereby driving the transmission gear 7 to rotate synchronously through the output gear 8.

[0033] In this technical solution, a ring-shaped gear ring 10 is fixedly connected to the middle of the housing 3. The gear ring 10 is meshed with the transmission gear 7. When the transmission gear 7 rotates, it drives the gear ring 10 to rotate, thereby driving the housing 3 to rotate inside the support 2.

[0034] In this technical solution, the enclosure 11 is a ring structure, and the diameter of one end of the enclosure 11 is larger than the diameter of the other end. Several uniformly distributed screens 12 are fixedly connected to the middle of the enclosure 11. When fertilizer falls onto the enclosure 11, the structure of the enclosure 11 causes the fertilizer to move slowly forward as it rotates.

[0035] In this technical solution, the shell 3 is provided with several evenly distributed first discharge ports 13 and second discharge ports 14 on both sides. The first discharge ports 13 are respectively arranged on one side of the enclosure plate 11, and the second discharge ports 14 are located on one side of the inner wall of the shell 3. The fertilizer that has been screened by the screen 12 falls into the interior of the shell 3 and is discharged through the second discharge port 14. The fertilizer that has not been screened by the screen 12 falls from the first discharge port 13.

[0036] In this technical solution, the feeding mechanism includes a feeding hopper 15, which is fixedly connected to the middle of one side of the housing 3. The feeding hopper 15 is fixedly connected to the bearing 17 through several evenly distributed supports 16. Fertilizer can be fed into the feeding hopper 15, so that the fertilizer falls onto the enclosure plate 11 for conveying. The feeding hopper 15 is used for feeding fertilizer, and it can be added in real time during use without causing fertilizer to fall. The feeding hopper 15 and the bearing 17 are installed through the feeding hopper 15, which can realize the stable rotation of the screw shaft 18.

[0037] In this technical solution, the spreading mechanism includes a vertical plate 19, on the top of which a conveying motor 20 is fixedly installed. The output end of the conveying motor 20 is fixedly connected to a spiral shaft 18. The two ends of the spiral shaft 18 are respectively rotatably connected to a bearing 17 and the inside of the housing 3. The spiral shaft 18 is located inside the surrounding plate 11. When the housing 3 drives the surrounding plate 11 to rotate, the conveying motor 20 on the vertical plate 19 drives the spiral shaft 18 to rotate. The spiral shaft 18 rotates on one side of the housing 3 and inside the bearing 17. When the conveying motor 20 rotates, it drives the spiral shaft 18 to rotate inside the housing 3. The blades of the spiral shaft 18 push the upper layer of fertilizer in the opposite direction of the conveying direction, thereby spreading the fertilizer evenly to ensure that the fertilizer thickness passing through the screen 12 is consistent and to ensure screening efficiency. When the spiral shaft 18 and the housing 3 rotate in opposite directions, the contact area of ​​the fertilizer on the surface of the screen 12 can be increased, thereby improving the screening effect.

[0038] In this technical solution, both sides of the bottom plate 1 are fixedly connected to the collection trough 21. The collection trough 21 is correspondingly arranged on both sides of the shell 3, and the two collection troughs 21 are respectively located below the first discharge port 13 and the second discharge port 14. The fertilizer after screening is transported to the outside of the shell 3 in sequence and collected and stored through the collection trough 21.

The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
