[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The building sand and gravel material screening machine involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1:

[0026] like Figure 1-7As shown, a building sand and gravel material screening machine includes a screening frame 1, with a screening mesh 3 fixedly installed inside the screening frame 1. The bottom of the inner wall of the screening frame 1 and the screening mesh 3 are both inclined to the lower right. An inclined discharge plate 31 is fixedly connected to the right end of the screening mesh 3. A base 4 is provided below the screening frame 1, and a vibrating screening mechanism 2 is installed on the top of the base 4. The vibrating screening mechanism 2 includes a support frame 21, the bottom of which is fixedly connected to the top of the base 4. A rotating shaft 23 is provided at the upper part of the inside of the support frame 21, and multiple eccentric blocks 25 are fixedly installed on the outer wall of the rotating shaft 23. A protective cover 22 is fixedly connected to the front end of the support frame 21, and a motor 221 is provided inside the protective cover 22. The motor 221 is fixedly installed below the front end of the support frame 21, and a drive sprocket 222 is fixedly connected to the output end of the motor 221. A transmission chain is provided on the outer wall of the drive sprocket 222. A bearing 24 is fixedly installed on the upper part of the front and rear ends of the support frame 21. The outer wall of the rotating shaft 23 is rotatably installed inside the bearing 24. The front end of the rotating shaft 23 extends into the interior of the protective cover 22 and is rotatably connected to the inner wall of the protective cover 22. A driven sprocket 224 is fixedly sleeved on the front end of the outer wall of the rotating shaft 23. The outer wall of the driven sprocket 224 meshes with the top end of the inner wall of the transmission chain 223. The outer wall of the driving sprocket 222 meshes with the bottom end of the inner wall of the transmission chain 223. The driving sprocket 222 and the driven sprocket 224 are connected by the transmission chain 223. A striking plate 26 is fixedly connected to the bottom of the screening frame 1. The striking plate 26 is located above multiple eccentric blocks 25. Support springs 6 are fixedly connected to the four corners of the bottom of the screening frame 1. Support frames 5 are fixedly connected to the four corners of the top of the base 4. The bottom end of the support spring 6 is fixedly connected to the top of the support frame 5.

[0027] In this embodiment, the support spring 6 provides elastic support for the screening frame 1. The protective cover 22 protects the internal components, including the motor 221, drive sprocket 222, transmission chain 223, and driven sprocket 224. The bearings 24 at both ends of the support frame 21 support the rotating shaft 23. The motor 221, drive sprocket 222, transmission chain 223, and driven sprocket 224 work together to drive the rotating shaft 23 to rotate within the bearings 24. Simultaneously, the rotating shaft 23 drives multiple eccentric blocks 25 to rotate. The eccentric block 25 is used to strike the striking plate 26, thereby causing the screening frame 1 and the screening screen 3 to vibrate. At this time, due to the vibration of the screening screen 3, small particles of sand and gravel are screened to the bottom of the inner cavity of the screening frame 1, while large particles of sand and gravel are blocked above the screening screen 3. Since the bottom of the inner cavity of the screening frame 1 and the screening screen 3 are both inclined to the lower right, large particles of sand and gravel are discharged through the inclined discharge plate 31 at the right end of the screening screen 3. After screening, small particles of sand and gravel are discharged through the right end of the bottom of the inner wall of the screening frame 1, which facilitates the screening of large and small particles of sand and gravel.

[0028] Example 2:

[0029] like Figure 1-7 As shown, a dust-reducing mechanism 7 is installed on the left side of the screening frame 1. The dust-reducing mechanism 7 includes a collection tank 71, which is fixedly installed on the left side of the screening frame 1. A suction pump 74 is provided on the top of the collection tank 71, and the suction end of the suction pump 74 is fixedly installed on the top of the collection tank 71. Two conduits 72 are fixedly connected to the top of both the front and rear sides of the collection tank 71. The two conduits 72 are distributed on the front and rear sides of the screening frame 1. Multiple suction tubes 73 are fixedly connected to the front and rear sides of the screening frame 1. One end of the multiple suction tubes 73 extends into the interior of the screening frame 1 and is located in the screening mesh 3. Above, a protective filter screen is fixedly connected to one end of the suction tube 73, and the other ends of multiple suction tubes 73 are fixedly connected to one side of two guide tubes 72. An arc-shaped dust filter screen 75 is fixedly installed above the inner cavity of the collection tank 71. A collection cylinder 76 is movably sleeved inside the collection tank 71. The collection cylinder 76 is located below the arc-shaped dust filter screen 75. A limiting block 77 is fixedly connected to the bottom of the collection cylinder 76. The outer wall of the limiting block 77 is threadedly sleeved on the bottom end of the inner cavity of the collection tank 71. A sealing ring 78 is fixedly embedded in the inner wall of the collection tank 71. The inner wall of the sealing ring 78 is movably sleeved on the upper part of the outer wall of the collection cylinder 76.

[0030] In this embodiment, the protective filter screen protects one end of the suction tube 73, preventing sand and gravel particles from entering its interior. The air pump 74 extracts air from the collection tank 71, creating suction. The conduit 72 and multiple suction tubes 73 draw dust generated during sand and gravel sieving into the collection tank 71. Simultaneously, an arc-shaped dust filter 75 filters the dust, preventing it from entering the air pump 74. After suction, the dust falls into the collection cylinder 76 inside the collection tank 71 for collection. If needed... When cleaning the dust inside the collection cylinder 76, the limiting block 77 can be screwed off. The limiting block 77 simultaneously pulls the collection cylinder 76 from the bottom of the inner cavity of the collection tank 71, thus cleaning the dust inside the collection cylinder 76. Then, the collection cylinder 76 is moved into the inside of the collection tank 71, and the limiting block 77 at the bottom of the collection cylinder 76 is screwed onto the bottom end of the inner cavity of the collection tank 71, thus installing the collection cylinder 76 into the inside of the collection tank 71. The upper part of the outer wall of the collection cylinder 76 is fitted onto the inner wall of the sealing ring 78, using the sealing ring 78 to increase the sealing between the collection cylinder 76 and the collection tank 71.

[0031] In summary, as Figure 1-7As shown, in use, the construction sand and gravel screening machine places the construction sand and gravel on the left side of the top of the screening mesh 3 inside the screening frame 1. At this time, the output end of the motor 221 drives the drive sprocket 222 to rotate. The drive sprocket 222 drives the driven sprocket 224 to rotate through the transmission chain 223. The driven sprocket 224 drives the rotating shaft 23 to rotate inside the bearing 24. The rotating shaft 23 simultaneously drives multiple eccentric blocks 25 to rotate. The rotation of the eccentric blocks 25 strikes the striking plate 26, thereby causing the screening frame 1 and the screening mesh 3 to vibrate. The support spring 6 provides elastic support for the screening frame 1. At this time, due to the vibration of the screening mesh 3, small sand and gravel particles are screened to the bottom of the inner cavity of the screening frame 1, while large sand and gravel particles are blocked above the screening mesh 3. Large sand and gravel particles are discharged through the inclined discharge plate 31 on the right side of the screening mesh 3. After screening, small sand and gravel particles are discharged through the right side of the bottom of the inner wall of the screening frame 1.

[0032] While screening the sand and gravel, the air pump 74 draws air from the inside of the collection tank 71 and creates suction in the collection tank 71. The dust generated during the screening process is sucked into the collection tank 71 by the conduit 72 and multiple suction tubes 73. At the same time, it is filtered by the arc-shaped dust filter 75. After suction, the dust falls into the collection cylinder 76 inside the collection tank 71 and is collected in a concentrated manner by the collection cylinder 76.
