Description

Technical Field

[0001] This utility model relates to the field of construction technology, specifically to a sand screening machine for construction. Background Technology

[0002] A sand screening machine is a type of sand mining machinery used to separate coarse and fine materials. It is widely used in construction, mining, metallurgy and other fields. Sand screening machines can be divided into drum sand screening machines and vibrating sand screening machines according to the screening method. Vibrating sand screening machines use vibration to make the material jump and separate on the screen, resulting in a fast screening speed.

[0003] During the sand screening process, the vibrating sand screening machine sorts qualified sand and gravel particles. In actual use, some stones are the same size as the screen holes, which can cause them to get stuck inside the screen holes during screening, resulting in blockage and reducing the efficiency of sand and gravel screening. Therefore, a sand screening machine for construction is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that some stones are the same size as the sieve holes, which causes the stones to get stuck inside the sieve holes during the screening process, resulting in clogging of the sieve holes and reducing the efficiency of sand and gravel screening. This utility model provides a sand screening machine for construction.

[0028] like Figures 1 to 5As shown, a sand screening machine for construction includes: a screening frame 1, a support frame 101 on the outside of the screening frame 1, and a guide 3 installed on the outside of the support frame 101; a screening element 2, located inside the screening frame 1, used for screening sand and gravel; and a vibrating element 4, located inside the screening frame 1, used for striking the screening element 2. Specifically, during use, the sand and gravel to be screened are first added to the top of the screening element 2 through the guide 3, so that the screening frame 1 cooperates with the screening element 2 to screen the sand and gravel, ensuring that the sand and gravel meet the usage requirements. During the screening process, the vibrating element 4 strikes the screening element 2 to prevent the sand and gravel from clogging the screening element 2 and ensure the stability of the sand and gravel screening. The guide 3 can control the flow rate of the added sand and gravel during use to prevent the sand and gravel from accumulating on the top of the screening element 2. An electric motor for providing power is also installed inside the support frame 101. During use, the screening frame 1 cooperates with the screening element 2 to guide sand and gravel of different diameters.

[0029] like Figures 1 to 5 As shown, a connecting component is also installed between the screening frame 1 and the support frame 101. Specifically, the connecting component is a spring, which ensures that the screening frame 1 can vibrate relative to the support frame 101 during use.

[0030] like Figures 1 to 5 As shown, the screening component 2 includes a screen 201, which is installed inside the screening frame 1. Connecting plates 202 are provided on both sides of the screen 201. At least one guide rod 204 is slidably connected inside the connecting plate 202. The guide rod 204 slides inside the connecting plate 202, and the sliding direction of the connecting plate 202 is perpendicular to its height. An installation strip 203 is provided on the outer side of the guide rod 204, and the installation strip 203 is connected to the screening frame 1. Specifically, during use, the screening frame 1, the installation strip 203, and the guide rod 204 work together to vibrate the connecting plate 202 and the screen 201, ensuring that the screen 201 can stably screen sand and gravel during use. The screen 201 and the connecting plate 202 are connected by bolts, facilitating the replacement of the screen 201's aperture size according to usage requirements.

[0031] like Figures 1 to 5 As shown, a first spring 205 is also sleeved on the outside of the guide rod 204. Specifically, during use, the first spring 205 provides support and thrust to the connecting plate 202, further ensuring that the connecting plate 202 can stably screen sand and gravel.

[0032] like Figures 1 to 5As shown, the vibrating component 4 includes a rotating shaft 102 and a connecting shaft 404. There are multiple rotating shafts 102 and connecting shafts 404, with each rotating shaft 102 corresponding to a different connecting shaft 404. The rotating shaft 102 rotates inside the screening rack 1. The outer wall of the rotating shaft 102 is provided with a fixing plate 401 and a fixing block 402 in sequence. There are multiple fixing blocks 402. The connecting shaft 404 is connected to the screening rack 1, and the axis of the connecting shaft 404 is parallel to the axis of the rotating shaft 102. A swing rod 405 is rotatably connected to the outside of the connecting shaft 404. A roller 407 is rotatably connected to the swing rod 405 relative to the fixed disk 401, and the roller 407 rotates outside the fixed disk 401. A second spring 408 and a support plate 403 are sequentially provided on the outer side of the swing rod 405 relative to the rotating shaft 102, and the support plate 403 is connected to the screening frame 1. Specifically, during the screening of sand and gravel, the rotating shaft 102 drives the fixed disk 401 and the fixed block 402 to rotate. During the rotation, the fixed block 402 pushes the swing rod 405 around the connecting shaft 404. The center rotates, and during the rotation of the swing rod 405, the second spring 408 is stretched. When the fixed block 402 separates from the roller 407, the swing rod 405 strikes the screen 201 under the pull of the second spring 408, thereby knocking the stones inside the screen holes and ensuring stability in the sand and gravel screening process. The cooperation between the roller 407 and the fixed block 402 avoids direct contact between the swing rod 405 and the fixed block 402. Both the fixed block 402 and the roller 407 are made of wear-resistant materials, thereby extending their service life. During use, the second spring 408 can provide the striking power to the swing rod 405, ensuring that the swing rod 405 can discharge the stones inside the screen holes. The rotating shaft 102 is connected to the motor via a belt. An eccentric block is also provided on the outside of the rotating shaft 102. During use, the eccentric block can drive the screening frame 1 to vibrate. The number of swing rods 405 can be selected according to the needs to ensure that the swing rods 405 can stably discharge the stones during use.

[0033] like Figures 1 to 5 As shown, the other end of the swing rod 405 is also provided with a striking block 406. Specifically, the striking block 406 is connected to the swing rod 405 by bolts or buckles. The striking block 406 can be cylindrical or square, thereby increasing the area of ​​the screen 201 to be struck and preventing the screen 201 from deforming during the striking process.

[0034] like Figures 1 to 5As shown, the working state of the sand screening machine for construction is as follows: When screening sand and gravel, the flow of sand and gravel is first limited by the guide 3 to ensure that the sand and gravel can flow evenly to the top of the screen 201, so that the screen 201 can stably screen the sand and gravel during use. When the screen 201 screens the sand and gravel, the swing rod 405 is driven to swing by the cooperation of the fixed plate 401 and the fixed block 402. During the swing, the swing rod 405 strikes the screen 201 through the striking block 406, thereby knocking out the stones inside the screen 201, ensuring that the screen 201 can stably screen the sand and gravel.

[0035] In summary, this utility model includes: a screening frame 1, a support frame 101 on the outside of the screening frame 1, and a guide 3 installed on the outside of the support frame 101; a screening element 2, which is set inside the screening frame 1 for screening sand and gravel; and a vibrating element 4, which is set inside the screening frame 1 for striking the screening element 2. This utility model, through the arrangement of the rotating shaft 102 and the vibrating element 4, achieves the cooperation of the rotating shaft 102, the fixed plate 401, the fixed block 402, the support plate 403, the connecting shaft 404, the swing rod 405, the striking block 406, the roller 407, and the second spring 408, thereby providing striking to the screen 201 during use, preventing stones from getting stuck inside the screen holes and causing blockage, thus ensuring the efficiency of sand and gravel screening.
