Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

Embodiment 1, as shown in fig. 1 to 3, a limestone particle screening device comprises a box body 1, a screen 2 and a bracket 3; the bottom opening of the box body 1 is provided, the screen cloth 2 is covered at the bottom opening of the box body 1, the screen cloth 2 is annular, the screen cloth 2 comprises at least two screen cloth parts 21 with different screen holes 22, and the screen cloth 2 is driven to rotate by the driving device 4 so that different screen cloth parts 21 are positioned at the bottom opening of the box body 1. The screen 2 is driven to run through the driving device 4, so that different screening parts 21 are positioned at the bottom of the box body 1, limestone particles with different particle sizes can be screened according to requirements, the screen 2 does not need to be manually replaced when the device is used for screening, and the purpose of quick adjustment can be achieved only by adjusting the screening parts 21 through the driving device 4, so that the device is high in efficiency and small in size.

Example 2, as shown in fig. 1 to 3, this example is a further improvement on the basis of example 1, and is specifically as follows:

the driving device 4 comprises a belt 41, at least two gear columns 42 and a motor 43; two gear columns 42 are horizontally arranged on the support 3, the screen 2 is sleeved on the two gear columns 42, the belt 41 is arranged inside two sides of the screen 2, the gear columns 42 are meshed with the belt 41, and the motor 43 is arranged on the support 3 and drives the gear columns 42 to rotate.

The motor 43 drives the gear column 42 to rotate, and the gear column 42 drives the belt 41 to move, so that the aim of driving the screen 2 to adjust is fulfilled, and the efficiency is higher; the two sides of the bottom of the box body 1 are respectively provided with the notch 11, and the screen 2 passes through the two notches 11, so that the screen 2 is just positioned at the bottom opening of the box body 1 and cannot deviate; in the specific implementation process, in order to achieve the purpose of more complete screening, in the screening process, the motor 43 rapidly rotates forward and reversely at a small angle so as to achieve the purpose that the position of the screen 2 moves and recovers, and the screen 2 is driven to vibrate through vibration of the motor 43, so that the screening effect is better.

Example 3 this example is a further improvement over example 1, as shown in fig. 1-3, and is specifically as follows:

the bottom of the box body 1 is provided with a collecting frame 5, and the collecting frame 5 is positioned inside the screen 2. So as to collect the sieved limestone particles. In the specific implementation process, the number of the gear columns 42 is two or four; when the number of the gear columns 42 is two, the screen 2 and the collection frame 5 are in the state shown in fig. 1 and 2; when the number of the gear columns 42 is four, the screen 2 is in a state as shown in fig. 3, and the four gear columns 42 are respectively arranged at the four corners of the screen 2, so that the height of the collecting frame at the bottom of the box body 1 can be increased, and the volume of the once-collected and screened limestone can be further increased.
