Description

Technical Field

[0001] The utility model mainly relates to the technical field of production and processing of compound microbial fertilizers, in particular to a granulator with adjustable particle size for producing compound microbial fertilizers. Background Art

[0002] The main function of the granulator is to granulate the wet powder raw materials. This process can improve the properties of the material, such as fluidity and solubility, while increasing the density of the material, making it easier to store and transport. The granulator is widely used in many industries.

[0003] When using a general granulator, it can only produce fertilizer granules of one particle size. When it is necessary to produce granules of multiple particle sizes, it is necessary to replace the granulator with one that produces different particle sizes, or to use tools to disassemble the granulator to replace parts. The operation is more troublesome, and the following deficiencies are generated in the actual production process:

[0004] Limited adaptability: Different crops and soil conditions may require different fertilizer particle sizes. Small-particle fertilizers are more suitable for precision fertilization methods such as foliar spraying or drip irrigation, while large-particle fertilizers are more suitable for soil broadcasting or mechanized seeding.

[0005] Insufficient resource utilization: Due to the single particle size, the distribution and dissolution rate of fertilizer in the soil may be uneven, thus affecting the fertilizer effect;

[0006] Limited production efficiency: During the production process, if only one particle size of fertilizer can be produced, then when market demand changes, the pelletizer may need to be shut down for adjustment or replacement of parts to adapt to the new particle size requirements.

[0007] In order to improve the adaptability and market competitiveness of the pellet mill, it is possible to consider improving the pellet mill to facilitate the production of fertilizers with various particle sizes, help meet market demand, and improve resource utilization efficiency.

Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0030] Please refer to the attached Figure 1-Figure 5 As shown, the utility model provides a technical solution: a granulator with adjustable particle size for producing compound microbial fertilizer, comprising a shell 10, characterized in that a cover plate 11 is provided at the upper end of the shell 10, a discharge port 12 is fixedly installed on the lower end side wall of the shell 10, an inclined baffle 13 is fixedly installed at the lower end of the discharge port 12 of the shell 10, a sleeve rod 14 is fixedly installed on the inclined baffle 13, a leak plate 25 is provided at the upper end of the sleeve rod 14, a fixed shaft 20 is fixedly installed at the lower end of the inner wall of the shell 10, the leak plate 25 is rotatably sleeved on the outer surface of the fixed shaft 20, a cross shaft 21 is provided at the upper end of the leak plate 25, a threaded groove 201 is opened at the upper end of the fixed shaft 20, the lower end of the cross shaft 21 is threadedly installed in the threaded groove 201, a knob 23 is fixedly installed on the upper end of the cross shaft 21, an adjusting mechanism is provided on the sleeve rod 14, and the cross shaft 21 can be removed from the fixed shaft 20 by cooperation between the threaded groove 201 in the fixed shaft 20 and the cross shaft 21.

[0031] In this embodiment, two pressing wheels 22 are rotatably mounted on both ends of the cross shaft 21. The two pressing wheels 22 are rotatably attached to the upper surface of the leaking plate 25 to facilitate squeezing the fertilizer.

[0032] In this embodiment, a rotating rod 24 is rotatably sleeved on the outer surface of the fixed shaft 20, and two clamping holes 241 are provided at the upper end of the rotating rod 24. The lower end of the leakage plate 25 is fixedly connected to two clamping blocks 252. The two clamping blocks 252 are respectively slidably engaged in the two clamping holes 241, and the leakage plate 25 is rotatably connected to the fixed shaft 20.

[0033] Specifically, by rotating the knob 23, the cross shaft 21 is driven to rotate on the fixed shaft 20, so that the lower end of the cross shaft 21 rotates out of the threaded groove 201 at the upper end of the fixed shaft 20, and at the same time, the leakage plate 25 is pulled to disengage the two clamping blocks 252 from the two clamping holes 241 at the upper end of the rotating rod 24, so that the operator can manually remove the leakage plate 25 from the shell 10, thereby facilitating the replacement of leakage plates 25 with different apertures to produce fertilizers with different particle sizes.

[0034] In this embodiment, the adjustment mechanism includes two arc-shaped connecting rods 31 slidably installed in the sleeve rod 14, and the upper ends of the two arc-shaped connecting rods 31 are fixedly connected to the scraper rod 30. Two sliding holes 141 are evenly opened on the upper end side wall of the sleeve rod 14, and the scraper rod 30 is slidably installed in the two sliding holes 141.

[0035] By adjusting the movement of the scraper rod 30 in the two sliding holes 141, the distance between the scraper rod 30 and the leaking plate 25 is adjusted. When the fertilizer is squeezed and falls from the leaking plate 25, the leaking plate 25 rotates and is knocked down by the obstruction of the scraper rod 30, which is convenient for producing fertilizers of different lengths and sizes.

[0036] In this embodiment, a number of latch teeth 311 are evenly provided on the side wall of one of the arc-shaped connecting rods 31, a fixed rod 102 is fixedly mounted on the inner wall of the shell 10, and a second motor 33 is fixedly mounted on one side of the fixed rod 102. The output end of the second motor 33 rotates through the outer surface of the fixed rod 102 and is fixedly connected to a circular gear 32. The circular gear 32 is engaged with the number of latch teeth 311. By starting the second motor 33 to drive the circular gear 32 to rotate, the circular gear 32 pushes the number of latch teeth 311 of one of the arc-shaped connecting rods 31 to move up and down, thereby adjusting the scraper rod 30 to slide up and down in the two sliding holes 141, and adjusting the distance between the scraper rod 30 and the leak plate 25.

[0037] In this embodiment, a fixing plate 101 is fixedly installed at the lower end of the inner wall of the shell 10, and a first motor 27 is fixedly installed on one side of the fixing plate 101. The output end of the first motor 27 rotates through the outer surface of the fixing plate 101, and the output end of the first motor 27 and the lower end of the rotating rod 24 are respectively fixedly connected to two bevel gears 26. The two bevel gears 26 are engaged with each other. By starting the first motor 27, one of the bevel gears 26 is driven to rotate, and the rotating rod 24 is driven to rotate through the transmission of the two bevel gears 26, thereby driving the leakage plate 25 to rotate.
