Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer equipment, in particular to a novel fertilizer screening machine. Background Art

[0002] Fertilizer refers to a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. It is one of the material bases of agricultural production, and can provide crops with the necessary nutrients, improve the structure and properties of the soil, and thus promote the growth and development of crops, and increase the yield and quality of crops. In the production process of fertilizers, the size of fertilizer particles may be uneven due to different manufacturing processes or due to improper handling of certain process links such as material crushing, mixing, etc. Therefore, it is necessary to screen the prepared granular fertilizers through a multi-stage screening device to ensure the overall quality of the fertilizer particles.

[0003] Due to the special physical and chemical properties of fertilizers, particles sometimes clump together. When these agglomerated fertilizers are vibrated, they are easily broken due to weak internal crystal connections or uneven pressure distribution between particles.

[0004] When the existing screening mechanism is screening fertilizers, fertilizer agglomeration often occurs, which not only causes the screen of the screening mechanism to be blocked, but also seriously affects the screening efficiency and effect. In addition, the agglomerated fertilizer is easily screened out by the screen, resulting in waste. In response to this situation, we provide a new type of fertilizer screening machine that can prevent blockage and improve screening efficiency. Utility Model Content

[0005] The embodiment of the utility model provides a novel fertilizer screening machine to solve the above-mentioned technical problems.

[0006] The utility model embodiment adopts the following technical scheme: it comprises a box body, an extrusion plate is slidably connected to the upper inner wall of the box body, a leakage hole is opened on the extrusion plate, a pressure plate is provided above the extrusion plate, the pressure plate is fixedly connected to the inner wall of the box body, an extrusion channel is surrounded between the pressure plate and the extrusion plate, a feeding channel connected to the extrusion channel is provided above the pressure plate, a pushing component is provided below the extrusion plate, the pushing component is used to drive the extrusion plate to move up and down, when the extrusion plate moves upward and contacts the bottom inner wall of the pressure plate, the agglomerated fertilizer in the extrusion channel is crushed, and the agglomerated fertilizer is crushed into multiple granular fertilizers, which is convenient for subsequent fertilizer screening.

[0007] Furthermore, the pushing assembly includes a motor and a cam connected to the output end of the motor. A pressure-bearing tube is connected to the inner wall of the box body through a fixed rod. The motor is connected to the inner wall of the pressure-bearing tube. The pushing assembly drives the extrusion plate to move up and down, thereby crushing the agglomerated fertilizer. When the extrusion plate moves downward, the pressure-bearing tube limits the extrusion plate.

[0008] Furthermore, a blocking piece is provided inside the feeding channel, and a push rod is fixedly connected to the outer wall above the extrusion plate. The diameter of the blocking piece is consistent with the diameter of the lower part of the feeding channel, and the diameter of the blocking piece is smaller than the diameter of the upper part of the feeding channel. When the push rod lifts the blocking piece, the fertilizer enters the box body from the gap between the blocking piece and the upper part of the feeding channel. When the push rod falls, the blocking piece falls under its own weight and blocks the entrance of the feeding channel, so that the fertilizer is fed intermittently without causing blockage due to excessive fertilizer.

[0009] Furthermore, guide rods are fixedly connected to both sides of the blocking member, and the other ends of the guide rods are slidably connected to the lower part of the feeding channel, so that the blocking member can move vertically inside the feeding channel to prevent it from going out of the feeding channel.

[0010] Furthermore, a plurality of pressing blocks are provided on the outer wall of the lower side of the pressure plate. When the extrusion plate moves upward and contacts the pressure plate, the pressing blocks further crush the agglomerated fertilizer in the extrusion channel, thereby improving the crushing effect.

[0011] Furthermore, a plurality of inclined sieve plates are provided inside the box body, and the aperture of the sieve plates gradually decreases from top to bottom. A plurality of discharge ports are opened on the lower box body, and the plurality of discharge ports correspond one-to-one to the plurality of sieve plates for screening fertilizer particles of different particle sizes.

[0012] At least one of the above technical solutions adopted in the embodiment of the utility model can achieve the following beneficial effects:

[0013] 1. In the utility model, the extrusion plate is driven to move upward by the jacking assembly. When the extrusion plate moves upward and contacts the inner wall at the bottom of the pressure plate, the agglomerated fertilizer in the extrusion channel is crushed by the extrusion plate, so that the agglomerated fertilizer is not easily screened out, thereby avoiding fertilizer waste.

[0014] 2. At the same time, the top rod above the extrusion plate pushes the blocking piece up, and the fertilizer enters the extrusion channel from the gap between the blocking piece and the feeding channel. When the extrusion plate moves downward, the blocking piece falls under its own weight, blocking the entrance of the feeding channel, so that the fertilizer is fed intermittently, which will not cause the screen to be blocked due to excessive fertilizer, thereby improving the screening efficiency.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0023] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment provides a novel fertilizer screening machine, comprising a box body 1, an extrusion plate 2 is slidably connected to the upper inner wall of the box body 1, the extrusion plate 2 is provided with a leakage hole 201, a pressure plate 3 is provided above the extrusion plate 2, the pressure plate 3 is fixedly connected to the inner wall of the box body 1, an extrusion channel 4 is surrounded between the pressure plate 3 and the extrusion plate 2, a feeding channel 5 connected to the extrusion channel 4 is provided above the pressure plate 3, a push component is provided below the extrusion plate 2, the push component is used to drive the extrusion plate 2 to move up and down, when fertilizer is poured into the feeding channel 5, the push component drives the extrusion plate 2 to move upward, when the extrusion plate 2 moves upward and contacts the inner wall at the bottom of the pressure plate 3, the gap in the extrusion channel 4 becomes smaller, so that the agglomerated fertilizer in the extrusion channel 4 is crushed and falls from the leakage hole 201, so that the agglomerated fertilizer is not easily screened out, thereby avoiding fertilizer waste.

[0025] Preferably, the pushing assembly includes a motor 6 and a cam 7 connected to the output end of the motor 6. A pressure tube 9 is connected to the inner wall of the box body 1 through a fixing rod 8. The motor 6 is connected to the inner wall of the pressure tube 9. When the motor 6 drives the cam 7 to rotate, the cam 7 will push the extrusion plate 2 to make reciprocating motion in the vertical direction. When the extrusion plate 2 is driven to move upward, the extrusion plate 2 crushes the agglomerated fertilizer in the extrusion channel 4. When the cam 7 does not contact the extrusion plate 2, the extrusion plate 2 moves downward under its own weight. When the upper end of the pressure tube 9 contacts the extrusion plate 2, the extrusion plate 2 will be limited by the pressure tube 9 to stop the extrusion plate 2 from moving downward.

[0026] Preferably, a blocking piece 10 is provided inside the feeding channel 5. The blocking piece 10 is spherical, and a push rod 11 is fixedly connected to the outer wall above the extrusion plate 2. The diameter of the blocking piece 10 is smaller than the upper diameter of the feeding channel 5. When the push rod 11 lifts the blocking piece 10, a gap is generated between the blocking piece 10 and the upper part of the feeding channel 5, and the fertilizer enters the extrusion channel 4 from the gap between the blocking piece 10 and the upper part of the feeding channel 5. When the push rod 11 falls, the blocking piece 10 falls under its own weight. Since the diameter of the blocking piece 10 is consistent with the diameter of the lower part of the feeding channel 5, the entrance of the feeding channel 5 is blocked, so that the fertilizer is fed intermittently, and blockage will not be caused by too much fertilizer being fed at one time.

[0027] Preferably, guide rods 12 are fixedly connected on both sides of the blocking member 10, and the other end of the guide rods 12 is slidably connected to the lower part of the feeding channel 5, so that the blocking member 10 can move vertically inside the feeding channel 5 to prevent the blocking member 10 from being ejected from the feeding channel 5 by the ejecting assembly.

[0028] Preferably, a plurality of pressing blocks 13 are provided on the lower outer wall of the pressure plate 3. When the extrusion plate 2 moves upward and contacts the pressure plate 3, the pressing blocks 13 crush the agglomerated fertilizer in the extrusion channel 4 to disperse the agglomerated fertilizer and improve the crushing effect.

[0029] Preferably, a plurality of inclined sieve plates 14 are provided inside the box body 1, and the aperture of the sieve plates 14 gradually decreases from top to bottom. A plurality of discharge ports 15 are opened on the lower box body 1, and the plurality of discharge ports 15 correspond one-to-one to the plurality of sieve plates 14. The sieve plates 14 are used to screen fertilizers of different particle sizes. Larger fertilizer particles remain on the upper sieve plate 14, and smaller fertilizer particles remain on the lower sieve plate 14. The screened fertilizers are discharged through the corresponding discharge ports 15.
