Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to an automatic screening device for fertilizer granules. Background Technology

[0002] Fertilizers are substances that provide one or more essential nutrients for plants, improve soil properties, and enhance soil fertility. They are one of the material foundations of agricultural production. Inorganic fertilizers include nitrogen fertilizers such as urea, ammonium bicarbonate, and ammonium sulfate; phosphate fertilizers such as superphosphate and calcium magnesium phosphate; potassium fertilizers such as potassium chloride and potassium sulfate; and compound fertilizers containing two or more major nutrients, such as diammonium phosphate and potassium nitrate.

[0003] Some fertilizers are prone to clumping after storage, such as phosphate fertilizers which easily absorb moisture and clump. Therefore, they are screened out using a sieving device before use. Traditional sieving devices require manual removal of clumps from the screen after sieving to allow the screen to continue screening. This process is labor-intensive and inconvenient. Therefore, this invention proposes an automatic fertilizer granule sieving device to address the shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an automatic fertilizer granule screening device. By rotatably connecting one end of the screen plate to the screen plate frame via a rotating shaft, and extending one end of the screen plate beyond one side of the screen plate frame, and by setting a separation control mechanism connected to the rotating shaft, the screen plate can be rotated using the separation control mechanism. This allows the clumps of fertilizer intercepted on the screen plate to be poured downwards, eliminating the need for manual dumping of the clumps. This effectively improves the efficiency of fertilizer screening operations and saves labor.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic fertilizer granule screening device includes a support base, a screen frame, a screen plate, and a separation control mechanism. The screen frame has a screen plate at its bottom, and a rotating shaft is rotatably mounted on one side of the lower interior of the screen frame. One end of the screen plate is connected to the rotating shaft, and the other end of the screen plate extends to one side of the screen frame. Moving blocks are symmetrically arranged on both the front and rear sides of the screen frame. A sliding groove is provided on the inner sidewall of the support base, and the moving blocks are slidably connected to the sliding groove. A standing base is located above one end of the support base, and a driving cylinder is mounted on the standing base. The output end of the driving cylinder is connected to one sidewall of the screen frame. A separation control mechanism is installed on the screen frame and is connected to the rotating shaft.

[0007] A further improvement is that the portion of the sieve plate located inside and below the sieve tray frame has a mesh structure, and the end of the sieve plate extending out of one side of the sieve tray frame has a flat plate structure.

[0008] A further improvement is that the separation control mechanism includes gears, racks, and moving grooves. Moving grooves are provided on both sides of one end of the screen frame, and racks are also provided on the moving grooves. Gears are provided at both ends of the rotating shaft after passing through the side walls of the screen frame, and the gears mesh with the racks.

[0009] A further improvement is that a crossbar is connected between the upper ends of the two racks, an installation groove is provided on one side wall of the screen frame, a lifting cylinder is provided in the installation groove, and the output end of the lifting cylinder is connected to the bottom of the crossbar.

[0010] A further improvement is that: a first baffle is provided on both the front and rear sides of the bottom of the sieve tray frame, and one end of the first baffle extends out of one side of the bottom of the sieve tray frame.

[0011] A further improvement is that a second baffle is provided on both the front and rear sides of the top of one end of the sieve plate extending out of the sieve disc frame.

[0012] The beneficial effects of this utility model are as follows: By connecting one end of the sieve plate to the sieve disc frame via a rotating shaft and extending one end of the sieve plate out of one side of the sieve disc frame, and by setting a separation control mechanism connected to the rotating shaft, the sieve plate can be rotated by the separation control mechanism, thereby realizing the downward pouring of the clumps of fertilizer intercepted on the sieve plate without the need for manual pouring of the clumps of fertilizer, which can effectively improve the efficiency of fertilizer screening and save labor.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1-4 As shown in the figure, this embodiment proposes an automatic fertilizer granule screening device, including a support base 1, a screen frame 2, a screen plate 3, and a separation control mechanism. The screen frame 2 has a screen plate 3 at its bottom. A rotating shaft 4 is rotatably provided on one side of the lower part of the screen frame 2. One end of the screen plate 3 is connected to the rotating shaft 4, and the other end of the screen plate 3 extends to one side of the screen frame 2. Moving blocks 5 are symmetrically provided on the front and rear sides of the screen frame 2. A sliding groove 6 is provided on the inner side wall of the support base 1. The moving blocks 5 are slidably connected to the sliding groove 6. A standing base 7 is provided on one end of the support base 1. A driving cylinder 8 is provided on the standing base 7. The output end of the driving cylinder 8 is connected to one side wall of the screen frame 2. A separation control mechanism is installed on the screen frame 2 and is connected to the rotating shaft 4.

[0020] When the fertilizer screening device of this utility model screens fertilizer, the fertilizer is put into the screen plate frame 2, and then the drive cylinder 8 is started to drive the screen plate frame 2 to move back and forth on the sliding groove 6 on the inner side wall of the support base 1 to achieve screening. Fertilizer particles pass through the screen plate 3, while clumps of fertilizer are trapped on the screen plate 3. When it is necessary to clean the clumps of fertilizer on the screen plate 3, the drive separation control mechanism is used to control the rotation of the rotating shaft 4, so that the screen plate 3 follows the rotation of the rotating shaft 4 and forms an inclined shape. Then the clumps of fertilizer slide down the screen plate 3 to the designated position (when controlling the rotation of the rotating shaft 4, the output end of the drive cylinder 8 is kept in the maximum extension state. At this time, since one end of the screen plate 3 extends to one side of the screen plate frame 2, it can be ensured that the clumps of fertilizer will not be poured into the fertilizer).

[0021] The portion of the sieve plate 3 located inside and below the sieve tray frame 2 has a mesh structure, while one end of the sieve plate 3 extending out of the sieve tray frame 2 has a flat plate structure. This flat plate structure at one end ensures that clumps of fertilizer slide down more smoothly.

[0022] The separation control mechanism includes gears 9, racks 10, and moving grooves 11. Moving grooves 11 are provided on both side walls of one end of the screen frame 2, and racks 10 are also provided on the moving grooves 11. Gears 9 are provided at both ends of the rotating shaft 4, extending through the side walls of the screen frame 2, and mesh with the racks 10. A crossbar 12 connects the upper ends of the two racks 10. An mounting groove 13 is provided on one side wall of the screen frame 2, and a lifting cylinder 14 is installed within the mounting groove 13. The output end of the lifting cylinder 14 is connected to the bottom of the crossbar 12. When it is necessary to control the rotation of the rotating shaft 4, the lifting cylinder 14 is activated to extend and lift the crossbar 12. At this time, the racks 10 connected to the crossbar 12 move upward within the moving grooves 11, driving the rotating shaft 4, on which the gears 9 are mounted, to rotate.

[0023] The sieve frame 2 is provided with a first baffle 15 on both the front and rear sides of its bottom, with one end of the first baffle 15 extending out of one side of the bottom of the sieve frame 2. The sieve plate 3 is provided with a second baffle 16 on both the front and rear sides of the top of one end extending out of one side of the sieve frame 2. By setting the first baffle 15 and the second baffle 16, it can be ensured that when the sieve plate 3 is tilted to discharge clumps of fertilizer, the clumps of fertilizer will not fall from both sides of the sieve plate 3, and the clumps of fertilizer can be fully discharged to the designated position.

[0024] This invention connects one end of the sieve plate 3 to the sieve tray frame 2 via a rotating shaft 4, and extends one end of the sieve plate 3 beyond one side of the sieve tray frame 2. By setting a separation control mechanism connected to the rotating shaft 4, the sieve plate 3 can be rotated using the separation control mechanism, thereby allowing the clumps of fertilizer intercepted on the sieve plate 3 to be poured downwards without the need for manual dumping of the clumps of fertilizer. This effectively improves the efficiency of fertilizer screening operations and saves labor.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
