[0045] In order to enable those skilled in the art to better understand the solution of the present application, the following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0046] Reference Figure 1-4 As shown in Figure 10, a high-fertility composite bacterial fertilizer rotary drum granulation equipment includes a rotary drum granulation body 1, a water spray pipe 2 is provided in the rotary drum granulation body 1, the water spray pipe 2 is fixed, a scraper assembly 3 is fixedly connected to the water spray pipe 2, a screening assembly 4 is fixedly connected to the rotary drum granulation body 1, and a grinding assembly 5 is fixedly connected to the water spray pipe 2; wherein

[0047] The drum granulation body 1 comprises: a drum body 11; and

[0048] The screening component 4 includes:

[0049] A connecting rod 41, one end of which is fixed on the drum body 11, the axis of the water spray pipe 2 coincides with the axis of the drum body 11, a turntable 42 is rotatably connected to the water spray pipe 2, the other end of the connecting rod 41 is fixedly connected to the turntable 42, and angle shafts 43 are slidably connected on both sides of the turntable 42, a spring 44 is sleeved on the angle shaft 43, one end of the angle shaft 43 is fixedly connected to a fixing rod 45, and a plurality of screening claws 46 are fixedly connected to the fixing rod 45.

[0050] The drum body 11 rotates during operation, while the water spray pipe 2 is fixed. The scraper assembly 3 is arranged in the drum body 11 and attached to the inner cavity wall of the drum body 11. Therefore, when the drum body 11 rotates, the scraper assembly 3 can scrape off the condensed fertilizer attached to the inner cavity wall of the drum body, and the scraped fertilizer falls into the grinding assembly 5 for grinding under the action of gravity. At the same time, since one end of the connecting rod 41 is fixed on the drum body 11, the axis of the water spray pipe 2 coincides with the axis of the drum body 11, and a turntable 42 is rotatably connected to the water spray pipe 2. The other end of the connecting rod 41 is fixedly connected to the turntable 42. The two sides of the turntable 42 are slidably connected with angled shafts 43, and a spring 44 is sleeved on the angled shaft 43. One end of the angled shaft 43 is fixedly connected to a fixing rod 45, which is fixed. A plurality of screening claws 46 are fixedly connected to the fixed rod 45, so when the drum body 11 rotates, the connecting rod 41 is driven to rotate, and then the turntable 42, the angle shaft 43, the fixed rod 45 and the screening claws 46 are driven to rotate around the axis of the water spray pipe 2, and the formed fertilizer particles settle at the bottom of the drum. Therefore, when the screening claws 46 rotate to the bottom of the drum, particles of different sizes are picked up. As the screening claws 46 continue to rotate, fertilizer particles of appropriate sizes leak out from the gap between the two screening claws 46, and unqualified large particles are picked up by the screening claws 46. As the screening claws 46 rotate, when the screening claws 46 rotate to an upwardly inclined position, the large particles on the screening claws 46 roll down to the grinding assembly 5 for grinding, and after being ground into powder, they leak out of the grinding assembly 5 for re-granulation.

[0051] Reference Figure 5 As shown, the scraper assembly 3 includes:

[0052] The bracket 31 has one end fixedly connected to the water spray pipe 2 , and the other end of the bracket 31 is fixedly connected to one end of the scraper 32 .

[0053] During the rotation of the drum body 11, since one end of the bracket 31 is fixedly connected to the water spray pipe 2 and the other end of the bracket 31 is fixedly connected to one end of the scraper 32, the scraper 32 is in a stationary state relative to the drum body 11. Therefore, the scraper 32 can be used to scrape off the fertilizer lumps on the inner wall of the drum body 11.

[0054] Reference Figure 6 As shown, the other end of the scraper 32 is fixedly connected to a trapezoidal block 33 , and one end of the angle shaft 43 is fixedly connected to a limiting shaft 431 .

[0055] When the limit shaft on the angle rod rotates to the position against the inclined surface of the trapezoidal block 33, the limit shaft slides on the inclined surface while continuing to rotate, and the angle shaft 43 slides on the turntable 42, and the spring 44 is compressed. When the limit shaft slides to the lower end surface of the trapezoidal block 33, the spring 44 is compressed to the maximum extent. During the continued rotation, the limit shaft slides over the lower end surface and enters the inclined surface on the other side of the trapezoidal block 33. During the continued sliding process, the spring 44 gradually recovers until the limit shaft completely leaves the inclined surface. In this process, the rotation of the screening claw 46 can be prevented from being blocked by the scraper 32.

[0056] A plurality of protrusions 421 are fixedly connected in an annular manner to one side of the rotating disk 42 .

[0057] A plurality of protrusions 421 are fixedly connected in an annular shape to one side of the rotating disk 42 . The rotating disk 42 is rotated to make the protrusions 421 push against the grinding assembly 5 , so that the grinding assembly 5 works.

[0058] Reference Figure 7-8 As shown, the grinding assembly 5 includes:

[0059] A material holding box 51 is provided with a push rod 52 in the material holding box 51, a filter hole 511 is provided at the bottom of the material holding box 51, the push rod 52 is slidably connected to the material holding box 51, a plurality of connection holes 521 are provided on the push rod 52, and a grinding roller 53 is rotatably connected to the plurality of connection holes 521.

[0060] The scraper 32 scrapes off the fertilizer agglomerated on the inner wall of the drum body 11, and drops it into the material holding box 51 by gravity. The screening claws 46 deliver the large-particle fertilizer into the material holding box 51 by rotation. When the turntable 42 rotates, the protrusion 421 is driven to rotate, and the protrusion 421 hits one end of the push rod 52, so that the push rod 52 slides in the material holding box 51, and then drives the grinding roller 53 to roll, so as to grind the block or large-particle fertilizer in the material holding box 51, and the ground fertilizer leaks out from the filter hole 511.

[0061] The grinding assembly 5 also includes:

[0062] A spring 54 is fixedly connected to the push rod 52 , and a hemispherical block 522 is fixedly connected to one end of the push rod 52 . The hemispherical block 522 abuts against one side of the rotating disk 42 .

[0063] The spring 1 54 is compressed by the contact between the protrusion 421 and the hemispherical block 522. When the protrusion 421 is separated from the hemispherical block 522, the spring 1 54 is reset. This reciprocating process causes the grinding roller 53 to roll back and forth, thereby repeatedly grinding the block or large-particle fertilizer in the material box 51.

[0064] Reference Fig. 9As shown, the drum granulation body 1 also includes:

[0065] A base 12, both sides of the upper end of the base 12 are rotatably connected to limit wheels 13, annular rods 14 are fixedly connected to both ends of the drum body 11, a gear ring 15 is fixedly connected to the position between the two annular rods 14, the annular rod 14 abuts against the limit wheel 13, the gear ring 15 meshes with the gear 16, the gear 16 is fixedly connected to the output end of the motor 17, and the motor 17 is fixed.

[0066] The motor 17 rotates to drive the gear 16 fixed thereto to rotate, and the meshing action of the gear 16 and the gear ring 15 drives the gear ring 15 to rotate, thereby causing the drum body 11 fixedly connected to the gear ring 15 to rotate and the annular rod 14 to rotate at the same time, and the annular rod 14 abuts against the limiting wheel 13, and the limiting wheel 13 is rotatably connected to the base 12, so that the friction force of the rotation of the drum body 11 is smaller.

[0067] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
