[0025] See Figures 1-2As shown, the limestone crushing and conveying mechanism of this embodiment includes a screening component 1, a crushing component 2, and a conveying component 3. The screening component 1 is provided with a screening box 11, a rotating structure 12, a screening screen 13, and a screening pipe 14. The screening box 11 has a feed inlet 111 on one side and a screening outlet 112 on the other side. The bottom end of the screening box 11 has a discharge outlet 113. The rotating structure 12 is installed on the screening box 11. The screening screen 13 is located at the discharge outlet 113. The screening pipe 14 is installed at the screening outlet 112. The crushing component 2 is a hammer crusher. The hammer crusher has a feed inlet and a discharge outlet. The feed inlet is connected to the discharge outlet 113. The discharge outlet is provided with a chute 21, which is connected to the conveying component 3.

[0026] This embodiment has a simple structure and reasonable design, integrating screening, crushing and conveying functions. The screening component 1 can screen out materials that meet the particle size requirements and effectively avoids clogging through rotary screening. The screened material is crushed to the required particle size by the crushing component 2, and then the conveying component 3 transports the crushed material to the designated location to achieve efficient limestone crushing and conveying.

[0027] In some embodiments, the screen 13 is flush with the bottom end of the screen opening 112.

[0028] In this embodiment, the bottom of the screen 13 is flush with the bottom of the screen opening 112, which ensures that the material can be evenly distributed during the screening process and smoothly discharged from the screen opening 112, avoiding the accumulation or blockage of material in the screen box 11 and improving screening efficiency.

[0029] In some embodiments, the rotating structure 12 includes a drive motor 121, a rotating shaft 122, and an agitating blade 123. The drive motor 121 is mounted on the screening box 11 and is drivenly connected to the rotating shaft 122. The rotating shaft 122 is connected to the screening box 11 through a bearing structure. The agitating blade 123 is mounted on the rotating shaft 122 and located inside the screening box 11.

[0030] In this embodiment, the rotating structure 12 specifically includes a drive motor 121, a rotating shaft 122, and a stirring blade 123. Driven by the drive motor 121, the stirring blade 123 can rotate in the screen box 11 to stir and turn the material, thereby improving the screening effect and preventing the material from forming clumps or sticking on the screen mesh 13, thus avoiding blockage.

[0031] In some embodiments, the feed inlet 111 is equipped with a feed cylinder 15, and the bottom end of the feed cylinder 15 is provided with a vibration motor 16.

[0032] In this embodiment, a vibration motor 16 is provided at the bottom of the feed cylinder 15 installed at the feed inlet 111, which can generate a vibration effect to help the material smoothly enter the screen box 11, avoid the material from being blocked at the feed inlet 111, and improve the material conveying efficiency.

[0033] In some embodiments, the discharge port 113 is provided with an electric baffle structure 17.

[0034] In this embodiment, the electric baffle structure 17 installed at the discharge port 113 can adjust the opening degree of the discharge port 113 as needed, thereby controlling the discharge speed and flow rate of the material and realizing precise control of material conveying.

[0035] In some embodiments, the chute 21 is tilted at an angle and a vibrator 22 is installed at its bottom.

[0036] In this embodiment, the chute 21 is tilted at an angle, and a vibrator 22 is installed at the bottom. This ensures that the crushed material can smoothly slide from the chute 21 onto the conveying assembly 3, avoiding material accumulation or blockage within the chute 21. Simultaneously, the vibrator 22 generates vibration, further aiding the material in sliding down faster and improving conveying efficiency.

[0037] In some embodiments, the conveying assembly 3 is configured as a belt conveyor.

[0038] In this embodiment, the conveying component 3 adopts the belt conveyor in the prior art, which has the advantages of simple structure, stable operation, large conveying capacity and easy maintenance, so as to stably convey the crushed material to the designated position.

[0039] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
