The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0019] See also Figure 1 and Figure 2 The utility model provides a stone screening device for concrete preparation, including a concrete stone screening box 1, a feeding assembly 2 is arranged on one side of the concrete stone screening box 1, the feeding assembly 2 includes a feeding barrel 21, a feeding funnel 22 is fixedly connected to the bottom of one side of the feeding barrel 21, and a driving shaft 23 is movably sleeved inside the feeding barrel 21, a driving motor 24 is fixedly connected to the top of the driving shaft 23, and a feeding blade 25 is fixedly installed outside the driving shaft 23, the feeding blade 25 is movably sleeved inside the feeding barrel 21, and the feeding blade 25 is spiral, and the top of the other side of the feeding barrel 21 is fixedly connected to the top of one side of the concrete stone screening box 1 through a feeding pipe 26;

[0020] In this embodiment, when the driving motor 24 is turned on, the driving shaft 23 rotates, and the driving shaft 23 drives the feeding blades 25 to rotate, and then the concrete stone is added from the feeding funnel 22, so that the concrete stone enters the feeding barrel 21. At this time, the concrete stone will be transported from a low place to a high place driven by the feeding blades 25, so that the concrete stone can enter the interior of the concrete stone screening box 1 along the feeding pipe 26, thereby making the concrete stone feeding process simpler and more convenient.

[0021] See also Figure 2, the interior of the concrete stone screening box 1 is respectively provided with a No. 1 screen 3 and a No. 2 screen 4 from top to bottom, the No. 1 screen 3 and the No. 2 screen 4 are both movably sleeved inside the concrete stone screening box 1, and the aperture value of the No. 1 screen 3 is larger than the aperture value of the No. 2 screen 4, and the bottoms of the No. 1 screen 3 and the No. 2 screen 4 are fixedly installed with a vibration motor 5, and the other side of the concrete stone screening box 1 is respectively fixedly connected with a No. 1 discharge pipe 6 and a No. 2 discharge pipe 7, and the bottom of the concrete stone screening box 1 is fixedly installed with a discharge funnel 8, the No. 1 discharge pipe 6 and the No. 2 discharge pipe 7 are respectively located at the top of the bottom ends of the No. 1 screen 3 and the No. 2 screen 4, and the No. 1 discharge valve and the No. 2 discharge valve are respectively fixedly installed on the outside of the No. 1 discharge pipe 6 and the No. 2 discharge pipe 7, and the discharge funnel 8 is fixedly installed with a discharge valve on the outside;

[0022] In this embodiment, when the concrete stone enters the interior of the concrete stone screening box 1, the concrete stone will fall downward and pass through the No. 1 screen 3 and the No. 2 screen 4 in sequence, which is convenient for multi-stage screening of the concrete stone and can effectively separate the concrete stones of different particle sizes. At the same time, the vibration motor 5 is started to make the No. 1 screen 3 and the No. 2 screen 4 vibrate themselves, which can accelerate the fluidity of the concrete stone on the surface of the No. 1 screen 3 and the No. 2 screen 4, so that the speed of concrete stone screening is accelerated, thereby improving the working efficiency of the screening equipment.

[0023] See also Figure 2 A top cover 9 is fixedly installed on the outside of the top of the concrete stone screening box 1, and the bottom of the top cover 9 is fixedly connected to the No. 1 screen 3 and the No. 2 screen 4 through a mounting assembly 10. The mounting assembly 10 includes a mounting rod 101 and a mounting sleeve 102. The mounting rod 101 is fixedly connected to the middle of the bottom end of the top cover 9, and the mounting rod 101 runs through the middle of the No. 1 screen 3 and the No. 2 screen 4. There are two mounting sleeves 102, and the two mounting sleeves 102 are respectively fixedly connected to the middle of the bottom ends of the No. 1 screen 3 and the No. 2 screen 4. The two mounting sleeves 102 are both movably sleeved on the outside of the mounting rod 101, and the two mounting sleeves 102 and the mounting rod 101 are fixedly connected by bolts 103;

[0024] In this embodiment, when the top cover 9 is opened, the top cover 9 and the concrete stone screening box 1 become loose, and the top cover 9 is lifted upward, and the mounting assembly 10 is used to drive the No. 1 screen 3 and the No. 2 screen 4 to move upward inside the concrete stone screening box 1, so that the No. 1 screen 3 and the No. 2 screen 4 can be moved out from the interior of the concrete stone screening box 1, and then the bolt 103 is rotated to separate it from the mounting sleeve 102 and the mounting rod 101. At this time, the mounting sleeve 102 and the mounting rod 101 become loose, so that the No. 1 screen 3 and the No. 2 screen 4 can be removed from the mounting rod 101, thereby facilitating the subsequent cleaning or replacement of the No. 1 screen 3 and the No. 2 screen 4.

[0025] The working principle and use process of the utility model are as follows: first, the driving motor 24 is turned on to rotate the driving shaft 23, and the driving shaft 23 drives the feeding blade 25 to rotate, and then the concrete stone is added from the feeding funnel 22, so that the concrete stone enters the feeding barrel 21, and at this time, the concrete stone is driven by the feeding blade 25 to be transported from a low position to a high position, so that the concrete stone can enter the interior of the concrete stone screening box 1 along the feeding pipe 26;

[0026] Then the concrete stone will fall down and pass through the No. 1 screen 3 and the No. 2 screen 4 in turn, which is convenient for multi-stage screening of the concrete stone, and can effectively separate the concrete stone of different particle sizes. At the same time, the vibration motor 5 is started to make the No. 1 screen 3 and the No. 2 screen 4 vibrate themselves, which can accelerate the fluidity of the concrete stone on the surface of the No. 1 screen 3 and the No. 2 screen 4;

[0027] Finally, when the concrete stone screening is completed, the top cover 9 is opened to loosen the top cover 9 and the concrete stone screening box 1, and the top cover 9 is lifted upward, and the installation assembly 10 is used to drive the No. 1 screen 3 and the No. 2 screen 4 to move upward inside the concrete stone screening box 1, so that the No. 1 screen 3 and the No. 2 screen 4 can be moved out from the interior of the concrete stone screening box 1, and then the bolt 103 is rotated to separate it from the mounting sleeve 102 and the mounting rod 101. At this time, the mounting sleeve 102 and the mounting rod 101 will be loose, so that the No. 1 screen 3 and the No. 2 screen 4 can be removed from the mounting rod 101, thereby facilitating the subsequent cleaning or replacement of the No. 1 screen 3 and the No. 2 screen 4.
