[0002] The horizontal centrifugal sand making machine disclosed on the Chinese patent website (publication number: CN202823485U) solves the existing centrifugal sand making machine, which is mainly broken by the hammering action of the impeller, but the impeller wears quickly, requires regular maintenance, and has high use costs. In addition, the material first contacts the outer end of the impeller blade, forming a large resistance to the rotation of the impeller, resulting in large power consumption, high energy consumption, limited feeding per unit time, and low processing efficiency. However, the following problems still exist:

[0003] In actual use, especially in the process of limestone mining, due to the presence of a large amount of fine materials such as lime, these fine materials enter the horizontal centrifugal sand making machine together with large pieces of materials. When the horizontal centrifugal sand making machine is working, when small pieces of materials collide with large pieces of materials, due to their small inertia and kinetic energy, their impact force on large pieces of materials may be relatively weak, and effective crushing effect cannot be achieved. On the contrary, small pieces of materials may play a certain buffering role, weakening the movement speed and kinetic energy of large pieces of materials, reducing the impact force on large pieces of materials, thereby affecting the crushing effect.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 4 A horizontal centrifugal sand making machine for limestone mining includes a centrifugal sand making machine body, which includes a base 1, a chassis 2 and a centrifugal wheel 3. The lower end of the chassis 2 is mounted on the upper surface of the base 1, and the inner wall of the chassis 2 is rotatably connected to the two ends of the centrifugal wheel 3 through bearings. A feed pipe 4 is mounted on the outer surface of the chassis 2, and a screening mechanism is mounted on the inner wall of the feed pipe 4. The screening mechanism includes a screen 5, which is in a circular ring shape and is located inside the feed pipe 4. A discharge pipe 51 is fixedly connected to the outer surface of the lower end of the feed pipe 4, and a discharge trough is provided on the inner bottom wall of the lower end of the feed pipe 4. The interior of the discharge pipe 51 is connected to the interior of the feed pipe 4 through the discharge trough.

[0025] In order to install the screen 5, a mounting ring 52 is fixedly connected to the front end surface of the screen 5, and the outer surface of the mounting ring 52 is rotatably connected to the inner wall of the feed pipe 4 through a bearing. The mounting ring 52 is used to movably install the screen 5, so that the mounting ring 52 can drive the screen 5 to rotate while facilitating the installation of the screen 5. A fixing rod 53 is fixedly connected to the inner side wall of the mounting ring 52, and a rotating shaft 54 ​​is fixedly inserted on the surface of the fixing rod 53. The two ends of the rotating shaft 54 ​​are respectively located on the inner side of the screen 5 and the inner side of the centrifugal wheel 3. The fixing rod 53 is used to connect the mounting ring 52 and the rotating shaft 54, so that the mounting ring 52 can be driven to rotate by the rotating shaft 54.

[0026] In order to assist the feed pipe 4 in feeding, a spiral blade 55 is fixedly connected to the surface of the rotating shaft 54, and the spiral blade 55 is located between the screen 5 and the centrifugal wheel 3. The spiral blade 55 is used to provide thrust, thereby facilitating the material to enter the centrifugal wheel 3 in the feed pipe 4. A transmission rod 56 is fixedly inserted on the surface of the rotating shaft 54, and both ends of the transmission rod 56 are fixedly connected to the inner wall surface of the centrifugal wheel 3. The transmission rod 56 is used to connect the centrifugal wheel 3 and the rotating shaft 54, so that the centrifugal wheel 3 can drive the rotating shaft 54.

[0027] A screening mechanism is installed in the feed pipe 4 of the centrifugal sand making machine body, and the screen 5 in the screening mechanism is used to screen the material in the feed pipe 4, so that fine materials are discharged outward through the discharge pipe 51, thereby reducing the probability of fine materials entering the centrifugal wheel 3 together with large materials, thereby reducing the probability of fine materials affecting the processing of large materials. At the same time, the power of the centrifugal wheel 3 is used to drive the rotating shaft 54 ​​in the screening mechanism, and then the screen 5 is driven by the rotating shaft 54 ​​to move, thereby increasing the use efficiency of the screen 5.

[0028] A slope plate 6 is fixedly connected to the inner wall of the chassis 2, and a drive motor 7 is installed on the surface of the base 1. The drive motor 7 drives the centrifugal wheel 3 through a transmission mechanism, and the slope plate 6 collides with the material to facilitate the crushing of the material. The transmission mechanism can be a transmission belt and pulley.

[0029] Working principle:

[0030] When in use, the centrifugal sand making machine is started, the driving motor 7 drives the centrifugal wheel 3 to rotate, and the material is added into the feed pipe 4. The material slides in the feed pipe 4 to the inner wall surface of the screen 5. The centrifugal wheel 3 drives the rotating shaft 54 ​​to rotate through the transmission rod 56, and the rotating shaft 54 ​​drives the screen 5 to rotate through the fixed rod 53. The deflection of the screen 5 buffers the material, so that the fine material in the material enters the discharge pipe 51 through the discharge slot at the lower end of the screen 5 and is discharged;

[0031] The rotating shaft 54 ​​drives the spiral blade 55 to rotate, pushing the remaining materials into the centrifugal wheel 3, and throwing them out after rotation. The thrown materials collide with the slope plate 6, break, and fall down and are discharged.
