[0029] Please refer to Figures 1-6 , the present utility model provides a technical solution:
[0030] A sand screening machine for civil engineering with a dust suppression structure, including a dust suppression structure, a filter screen 6, legs 3, a starting mechanism 9, a feed inlet 10 and a dust suction structure. The dust suppression structure is sleeved outside the filter screen 6. The legs 3 are installed at the bottom of the dust suppression structure. The starting mechanism 9 is installed at the top of the dust suppression structure. The feed inlet 10 is located on the left side of the dust suppression structure. The dust suction structure is located on the right side of the dust suppression structure;
[0031] The dust suppression structure includes a protective cover 1, a bottom shell 2 and a discharge port 4. The bottom shell 2 is located at the bottom of the protective cover 1 and is fixedly connected. The discharge port 4 is opened at the bottom inside the bottom shell 2. The filter screen 6 is located inside the protective cover 1. The legs 3 are installed at the bottom of the bottom shell 2. The starting mechanism 9 is installed at the top of the protective cover 1. The feed inlet 10 is located on the left side of the protective cover 1. The dust suction structure is located on the right side of the protective cover 1. Both ends of the surface of the filter screen 6 are connected to the inside of the protective cover 1 through rotating shafts;
[0032] The dust suction structure includes a dust suction mechanism 5 and a filtering mechanism 8. One end of the dust suction mechanism 5 extends into the inside of the filter screen 6. The dust suction mechanism 5 is installed on the right side of the protective cover 1. The filtering mechanism 8 is installed on the front side of the dust suction mechanism 5.
[0033] Specifically, the starting mechanism 9 includes two first gears 91, a belt 92 and an output motor 93. The output motor 93 is installed at the top of the protective cover 1. One of the first gears 91 is fixedly connected to the surface of the filter screen 6. The other first gear 91 is fixedly connected to the output end of the output motor 93. The two first gears 91 are connected by the belt 92. The filter screen 6 can be driven to rotate by the action of the output motor 93, the belt 92 and the two first gears 91. During the rotation of the filter screen 6, the dust and sand are driven to rotate. The sand falls into the bottom shell 2 through the filter element of the filter screen 6, while the dust is light in mass and is sucked away by the suction force generated by the blower 51.
[0034] Furthermore, the dust suction mechanism 5 includes a blower 51 and an extension pipe 52. The blower 51 is installed on the right side of the protective cover 1. The suction port of the blower 51 is fixedly connected to the extension pipe 52. One end of the extension pipe 52 is transported into the inside of the filter screen 6. The blower 51 can not only better suck dust through the extension pipe 52 to extend the suction distance, but also reduce the moving distance of the dust, avoiding the dust being blocked by the filter screen 6 during the flowing process.
[0035] It is worth noting that the filtering mechanism 8 includes a connecting pipe 81, a storage cylinder 82, and a filter cotton 83. One end of the connecting pipe 81 is sleeved and fixedly installed at the air outlet of the blower 51. The other end of the connecting pipe 81 is fixedly connected to the storage cylinder 82. A through hole is provided at the bottom end inside the storage cylinder 82. The filter cotton 83 is located at the bottom inside the storage cylinder 82 and above the through hole, which can achieve the separation between dust and air, and prevent the dust from being discharged outside after separating from the sand and affecting the air.
[0036] It should be noted that the feeding port 10 includes an opening 101 and a fixed pipe 102. The opening 101 is communicated with the fixed pipe 102. The surface of the fixed pipe 102 is fixedly connected to the protective cover 1. One end of the fixed pipe 102 is transported inside the filter net 6. The other end of the fixed pipe 102 is bent and fixedly communicated with the bottom of the opening 101. The fixed pipe 102 is fixedly connected to the protective cover 1 and is transported inside the filter net 6. This not only realizes the stability of the opening 101 but also does not affect the rotation of the filter net 6.
[0037] In addition, a partition 7 is fixedly connected to the surface of the filter net 6. The partition 7 is located on the right side of a gear 91 at the bottom end, preventing sand and dust from adhering to the gear 91 and the belt 92 and affecting the normal operation.
[0038] It has to be said that a buckle 11 is sleeved on the surface of the connecting pipe 81. The connecting pipe 81 is fixed to the air outlet of the blower 51 through the buckle 11, realizing the installation of the dust suction mechanism 5 and the filtering mechanism 8, enabling the user to remove the filtering mechanism 8 to clean the dust inside.
[0039] Working principle: The user turns on the output motor 93 and the blower 51. The rotation of the output motor 93 drives the top gear 91 to rotate. The rotation of the top gear 91 drives the bottom gear 91 to rotate through the belt 92. The rotation of the bottom gear 91 drives the filter net 6 to rotate. The rotating shaft sleeved on the surface supports the rotation of the filter net 6. The rotation of the blower 51 drives the air inside the filter net 6 to flow into the extension pipe 52, and the dust reaches the inside of the storage cylinder 82 through the extension of the extension pipe 52 and the connecting pipe 81, and finally is discharged outward through the filter cotton 83 and the through hole. After the two machines operate, the user pours into the opening 101. The sand flows into the inside of the filter net 6 through the fixed pipe 102. Since the filter net 6 is rotating, the sand moves while rotating along the track of the filter net 6. As the sand is rolled, the dust in the sand is sucked away by the suction force generated by the blower 51, and the sand flows out through the discharge port 4, while the dust stays inside the storage cylinder 82 through the filter cotton 83 to complete the operation. After the sand screening machine is used for a period of time, the user removes the buckle 11, then cleans the dust and the filter cotton 83, and reinstalls it after cleaning to complete the operation.

Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.

The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
