It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0035] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0036] according to Figures 1 to 5 As shown, the utility model provides a rotary granulator, comprising a body 1 and a granulation box 3;

[0037] A transmission motor (not shown) is provided inside the body 1, and a control button 2 for controlling the start and stop of the transmission motor is provided outside;

[0038] A granulation box 3 is arranged on one side of the machine body 1, and a granulation chamber is arranged in the granulation box 3, and a feed port 4 is arranged above the granulation chamber, and a discharge port 5 is arranged below the granulation chamber; a rotatably connected granulation assembly 8 is arranged in the granulation chamber, and one end of the granulation assembly 8 is connected to the output end of the transmission motor, so that the transmission motor drives the granulation assembly 8 to rotate;

[0039] An arc-shaped net 11 is also provided in the granulation box 3 , and the arc-shaped net 11 is located at the lower side of the granulation component 8 , and a plurality of evenly distributed granulation holes are provided on the arc-shaped net 11 , so that the material can be extruded along the granulation holes through the extrusion of the granulation component 8 .

[0040] The utility model can achieve effective stirring of materials and ensure uniform mixing of materials through the cooperation between the granulation component 8 and the arc-shaped net 11. At the same time, as the amount of materials gradually increases, the granulation component 8 squeezes the materials to squeeze the materials out of the granulation holes of the arc-shaped net 11.

[0041] Further, the granulation assembly 8 includes a transmission rod 15, a plurality of extrusion rods 14 and two connecting plates 13; a transmission rod 15 is provided on the opposite side of the two connecting plates 13, wherein one transmission rod 15 is connected to the output end of the transmission motor, and the other transmission rod 15 is rotatably connected to the side wall of the granulation box 3, and the two ends of the extrusion rod 14 are respectively welded on the outer peripheral surface of the two connecting plates 13, and the extrusion rod 14 and the arc net 11 are mutually fitted to cut off the extruded material so that the material is extruded in granular form. In this embodiment, the extrusion rod 14 in the granulation assembly 8 is mutually fitted to the arc net 11 to cut off the material through the extrusion rod 14, which effectively prevents the material from being in a strip structure. At the same time, the granulation assembly 8 can also stir the material through the plurality of extrusion rods 14 to ensure the uniform mixing effect of the material.

[0042] Furthermore, the cross section of the extrusion rod 14 is a triangular structure, one of the planes is welded to the outer peripheral surface of the connecting plate 13, and the edge opposite to the plane is in contact with the arc-shaped net 11. During implementation, one of the edges of the extrusion rod 14 is in contact with the arc-shaped net 11 to form a scraper structure, which can ensure the cutting effect of the material.

[0043] Furthermore, the extrusion rods 14 are arranged in a circular array on the outer peripheral surface of the connecting plate 13 with the center of the circle of the connecting plate 13 as the center. In practice, the spacing between the extrusion rods 14 can determine the size of the particles formed when the material is finally extruded from the granulation hole. The evenly arranged extrusion rods 14 can ensure that the particle size of the material particles is relatively uniform, and avoid the occurrence of particles with large particle size deviation.

[0044] Furthermore, two adjusting rods 12 are provided in the granulation box 3 . The two adjusting rods 12 are parallel to the transmission rod 15 of the transmission motor and are respectively located above the two sides of the granulation assembly 8 .

[0045] Both sides of the arc net 11 are connected to the adjusting rod 12 respectively. One end of the adjusting rod 12 away from the machine body 1 extends outside the granulation box 3 so that the distance between the arc net 11 and the granulation assembly 8 can be adjusted by rotating the adjusting rod 12 .

[0046] In this embodiment, according to the actual situation, specifically, including the space size of the granulation chamber and the diameter size of the granulation component 8, in order to ensure the versatility of the arc net 11, the utility model wraps the two sides of the arc net 11 around two adjusting rods 12 respectively, and by rotating the adjusting rods 12, the arc net 11 can be contracted or expanded, thereby meeting the needs in various situations.

[0047] Furthermore, an axially arranged slot 16 is provided on the adjusting rod 12, and a threaded hole penetrating the slot 16 is also provided on the side wall of the adjusting rod 12; the two sides of the arc-shaped net 11 can be respectively inserted into the corresponding slots 16, and a through hole corresponding to the threaded hole is provided on the arc-shaped net 11, so that the arc-shaped net 11 can be fixed in the adjusting rod 12 by bolts 17.

[0048] In this embodiment, the slot 16 limits the position of the arc-shaped net 11 , and finally the arc-shaped net 11 is fixed by the bolt 17 to prevent the arc-shaped net 11 from being separated from the adjustment rod 12 .

[0049] Furthermore, a ratchet 18 is further provided at one end of the adjusting rod 12 extending outside the granulating box 3, and a ratchet 10 cooperating with the ratchet 18 is provided on the outer side wall of the granulating box 3, so that the adjusting rod 12 can only rotate in one direction.

[0050] In this embodiment, after the arc net 11 is adjusted to a reasonable position by rotating the adjusting rod 12, with the continuous input of materials and the squeezing effect of the granulating assembly 8 on the materials, the arc net 11 will bear most of the pressure of the granulating assembly 8. In order to avoid the problem that the adjusting rod 12 rotates due to the force, resulting in a gap between the arc net 11 and the granulating assembly 8, and the material is extruded in a strip structure. The utility model sets a ratchet 18 on the outer side of the adjusting rod 12, and the ratchet 18 cooperates with the pawl 10 so that the adjusting rod 12 can only rotate in one direction, and the rotating rod of the adjusting rod 12 is only used for the contraction of the arc net 11.

[0051] Furthermore, a rotating handle 9 is provided at the end of the adjusting rod 12 outside the ratchet wheel 18 to facilitate operation by the staff.

[0052] Furthermore, a placement platform 6 is provided at the bottom of the machine body 1, and the placement platform 6 is located at the lower side of the granulation box 3, and the placement platform 6 is used to hold the collection box. During implementation, the placement platform 6 is set to a U-shaped structure, and the collection box is placed in the U-shaped opening. The cross bars on both sides of the placement platform 6 can play a positioning role for the collection box, ensuring that the discharge port 5 of the granulation box 3 is directly opposite to the collection box.

[0053] Furthermore, universal wheels 7 are provided at the bottom of the machine body 1 and the placement platform 6 to drive the machine body 1 to move, so as to facilitate the convenience of the utility model.
