A pair of crushing hammers and a pair of crushing hammers are symmetrically arranged on the rotating plate. The crushing hammers are located outside the crushing fixed teeth, and the crushing hammers are located between the crushing fixed teeth.

[0008] As a preferred embodiment of this utility model, the screen rotating assembly includes a second rotating shaft, which is movably mounted on the back plate of the crushing working shell via a second bearing seat. A gear is provided at the top of one end of the second rotating shaft located inside the crushing working shell. A second sprocket is also provided on the second rotating shaft, which is located directly below the first sprocket, and the first sprocket and the second sprocket are connected by a chain drive.

[0009] As a preferred embodiment of this utility model, a ring of transmission teeth is provided on the outer wall of the cylindrical screen near the mounting frame, and the gear meshes with several transmission teeth.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0028] like Figure 1-11 As shown, this utility model proposes a residue-proof universal pulverizer, which includes a pulverizing shell 1 with a feeding shell 10 at the bottom for receiving pulverized materials; a support table 19 extends from the outer wall to provide stable support for the equipment; inside the pulverizing shell 1, a cylindrical screen 2 is embedded in a mounting frame 16 for movable installation, and the screen can rotate around its axis; the inner wall of the pulverizing shell 1 is arranged with a ring of pulverizing fixing teeth 15 and a ring of pulverizing fixing teeth 111 from the inside out, forming a multi-stage pulverizing structure; at the same time, a scraper 18 is provided on the mounting blocks 17 distributed along the inner wall, and the scraper 18 is in close contact with the inner wall of the cylindrical screen 2 to remove residual materials from the screen; in addition, a mounting frame 110 is provided on the back of the pulverizing shell 1 as a fixed base for the pulverizing component 3;

[0029] The crushing assembly 3 includes a motor 30, which is mounted on a mounting frame 110. Its transmission end is connected to a sprocket 32 ​​and is connected to a rotating shaft 31 via a coupling 35. The rotating shaft 31 passes through the crushing working shell 1 and is supported by a bearing seat 33 for rotation. A pair of crushing hammers 34 and a pair of crushing hammers 37 are symmetrically arranged on the rotating plate 36 at the top of the shaft end. The crushing hammers 34 are located outside the crushing fixed teeth 111, and the crushing hammers 37 are located between the crushing fixed teeth 15 and the crushing fixed teeth 111, so as to achieve multi-angle crushing of materials in cooperation with the fixed teeth.

[0030] The screen rotation assembly 4 includes a second rotating shaft 40, which is mounted on the back plate of the crushing shell 1 via a second bearing seat 41. A gear 42 is provided at the shaft end, which meshes with the transmission gear 20 on the outer wall of the cylindrical screen 2. At the same time, the second sprocket 43 on the second rotating shaft 40 is connected to the first sprocket 32 ​​at the transmission end of the motor 30 via a chain 44. When the motor 30 is running, it drives the second rotating shaft 40 to rotate via chain drive, thereby driving the cylindrical screen 2 to rotate, and working with the inner wall scraper 18 to complete the screen cleaning.

[0031] The mounting ears 11 on both sides of the crushing shell 1 are connected to the first rotating drum 12 and the second rotating drum 52 respectively. The screw 13 on the first rotating drum 12 is set in the U-shaped plate 53 of the opening and closing door 50 and is fixed by the nut 14 to realize the opening and closing adjustment of the opening and closing door 50. The outer wall of the opening and closing door 50 is connected to the feeding pipe 54 and the feeding hopper 56 in sequence. A movable baffle 55 is set between the two to control the feeding amount. The inner wall of the opening and closing door 50 is also provided with the third crushing fixing tooth 57 corresponding to the second crushing fixing tooth 111 to further enhance the crushing effect.

[0032] When in use, the material is first poured into the feed hopper 56, the bottom of which is connected to the loading pipe 54. After starting the motor 30, the output shaft of the motor 30 drives the rotating shaft 31 to rotate at high speed through the coupling 35. The rotating plate 36 fixed on the rotating shaft 31 rotates accordingly. The operator can manually adjust the baffle 55 below the feed hopper 56 according to the material characteristics and crushing requirements to change the size of the discharge port and control the material conveying speed so that the material falls into the crushing shell 1 through the loading pipe 54.

[0033] Inside the crushing shell 1, a rotating shaft 31 runs through it. When the motor 30 drives the rotating shaft 31 to rotate, the crushing hammers 34 and 2 rotate, forming a striking effect. In addition, the crushing fixing teeth 15, 2 and 3 fixed on the inner wall of the crushing shell 1 are distributed at different heights and angles, forming a three-dimensional interlaced crushing space with the crushing hammers. During the falling process, the material is crushed by the impact and shearing of the crushing hammers, as well as by the collision and grinding with the crushing fixing teeth. The material that meets the mesh size requirements of the cylindrical screen 2 passes through the screen holes under the action of gravity and airflow and falls into the feeding shell 10.

[0034] During the crushing process, due to static electricity and material adhesion, material residue will remain on the surface of the cylindrical screen 2. When the motor 30 rotates, it drives the first sprocket 32 ​​through the transmission mechanism. The first sprocket 32 ​​and the second sprocket 43 are driven by the chain 44 to drive the second shaft 40. The gear 42 on the second shaft 40 meshes with the transmission teeth 20 on the outer side of the cylindrical screen 2, causing the screen to rotate at a low speed. Multiple high wear-resistant scrapers 18 are tightly attached to the inner wall of the screen. The gap between the cutting edge and the inner wall of the screen is extremely small. When the screen rotates, they continuously scrape the inner surface, peeling off the powdery material. The scraped material falls into the feed shell 10 through the screen holes and finally slides into the collection container, realizing the unified collection and residue cleaning of materials, ensuring that the crushing operation is efficient and continuous.

[0035] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
