[0002] Construction engineering is a broad concept, which covers the construction activities of civil construction engineering, building installation engineering, equipment pipeline engineering and other projects, and sand screening device is needed in the construction process to screen and filter sand to ensure that the quality of sand used in the construction process meets the requirements. The device separates impurities, stones and particles that do not meet the particle size requirements from the sand through a specific screening mechanism, thereby obtaining pure sand that meets the engineering requirements, to ensure the purity and quality of construction materials, which helps to improve the stability and durability of the project, and also helps to improve construction efficiency and reduce construction cost.
[0003] Most of the existing sand screening devices operate through vibration. During the screening process, new sand needs to be continuously added. If there is only one-way vibration, it may not be able to ensure that the sand can be evenly screened through the screen, which may result in a decrease in screening quality, such as some large particles or impurities that may not be effectively screened out, thereby affecting the quality of subsequent construction.
[0004] Therefore, in view of the above-mentioned problem that most of the existing sand screening devices operate through vibration, and during the screening process, new sand needs to be continuously added, which may not be able to ensure that the sand can be evenly screened through the screen, which may result in a decrease in screening quality, thereby affecting the quality of subsequent construction, a self-scooping and turning sand screening device for construction engineering can be designed, which installs an automatic scooping and turning structure on the sand screening device to improve the screening efficiency. SUMMARY

[0021] The self-scooping and turning sand screening device is shown in the drawing.
[0022] The self-scooping and turning sand screening device is shown in the drawing. Figures 1-4 The self-scooping and turning sand screening device is shown in the drawing.
[0023] The self-scooping and turning sand screening device is shown in the drawing. Figure 2In the embodiment, the support column 101 is installed at the lower end corner of the bearing platform 1, and the rectangular groove 102 is symmetrically arranged at the upper end edge of the bearing platform 1. When the sand screening device is running, the support column 101 stably supports the bearing platform 1, and the rectangular groove 102 facilitates the rotation of the roller 104. The bearing platform 1 is provided with the rectangular groove 102, and two groups of vertical plates 103 are symmetrically installed at the upper end of the rectangular groove 102. The two groups of vertical plates 103 are longitudinally symmetrically arranged, and the rotating shaft 105 is installed between the two groups of vertical plates 103. When the roller 104 rotates, the vertical plate 103 stably supports the roller 104, and the stability of the roller 104 is improved. The rotating shaft 105 is externally sleeved with the roller 104, and the first motor 106 is installed at one end of the rotating shaft 105. When the sand screening device needs to be run, the rotating shaft 105 drives the roller 104 to rotate along the rectangular groove 102 under the drive of the first motor 106. Thus, the roller 104 drives the drum sand screening machine body 202 to rotate along the annular sliding groove 204, which facilitates sand screening. The side baffle 107 is symmetrically arranged at the upper side of the bearing platform 1, and the guide pipe 108 is installed at the lower end between the two groups of side baffles 107. A plurality of vertical columns 109 fixedly connected with the bearing platform 1 are horizontally installed outside the side baffle 107. The side baffle 107 blocks and guides the screened sand, avoids the sand from being thrown out during rolling screening, and then guides the sand to fall through the guide pipe 108 for unified collection and use.
[0024] Please refer to Figure 3 In the embodiment, the annular sliding groove 204 is symmetrically arranged at the two end edges of the drum sand screening machine body 202, and the inlet 203 is arranged in the middle of one side of the drum sand screening machine body 202. The sand is sent into the drum sand screening machine body 202 through the inlet 203. During the rotation of the drum sand screening machine body 202, the sand is preliminarily screened through the drum sand screening machine body 202 to remove the larger impurities and stones in the sand. Then, the sand is further screened through the drum hole screen 201 to remove the particles that do not meet the particle size requirement. Then, the sand falls through the guide pipe 108, thereby completing the screening treatment of the sand.
[0025] Please refer to Figure 4 In the embodiment, the second motor 304 is installed at one end of the rotating column 301, and a plurality of circular holes 303 are uniformly arranged on the arc-shaped shovel plate 302. During the screening of the sand, the rotating column 301 drives the arc-shaped shovel plate 302 to rotate along the inner wall of the drum sand screening machine body 202 under the drive of the second motor 304, and the sand continuously entering the drum sand screening machine body 202 is shoveled and turned, so that the sand can uniformly pass through the drum sand screening machine body 202 and the drum hole screen 201. At the same time, when the arc-shaped shovel plate 302 shovels the sand, the sand can be auxiliary screened through the circular hole 303, thereby improving the efficiency of the screening device.
[0026] In the process of working, the sand is sent into the drum sand screening machine body 202 through the inlet 203, and then the roller 104 is driven to rotate by the first motor 106, so that the roller 104 drives the drum sand screening machine body 202 to rotate along the annular chute 204;
[0027] In the process of rotating the drum sand screening machine body 202, the sand is preliminarily screened by the drum sand screening machine body 202 to remove larger impurities and stones in the sand, and then further screened by the drum hole screen 201 to remove particles that do not meet the particle size requirements, and then the side baffle 107 blocks the screened sand to prevent the sand from being thrown out during rolling screening, and finally the side baffle 107 guides the sand to fall through the discharge pipe 108 for unified collection and use, thereby completing the screening process of the sand;
[0028] In the process of sand screening, the arc-shaped shovel plate 302 is driven to rotate along the inner wall of the drum sand screening machine body 202 by the second motor 304, which drives the rotating column 301 to shovel and turn the sand continuously entering the drum sand screening machine body 202, so that the sand can uniformly pass through the drum sand screening machine body 202 and the drum hole screen 201, and at the same time, the sand can be assisted in screening through the round hole 303 when the arc-shaped shovel plate 302 shovels the sand.
[0029] Through the above steps, the sand is first poured into the sand screening assembly, and then the roller 104 drives the sand screening assembly to rotate by the first motor 106, thereby performing two-stage sand screening. In the process, the sand in the sand screening assembly is shovelled and turned by the rotating shovel assembly to ensure that the sand can uniformly pass through the sand screening assembly for screening. By this method, different particle sizes of sand can be more accurately separated, and the screening quality is improved, which is of great significance for construction projects that need to strictly control the particle size of sand, can ensure the construction quality, and the sand screening device can automatically complete the process of sand screening and shovelling, without frequent manual operation, thereby greatly improving the sand screening efficiency. To solve the problem that most of the existing sand screening devices operate by vibration, and due to the need to continuously add new sand during the screening process, it may not be possible to ensure that the sand can uniformly pass through the screen for screening, which may lead to a decrease in screening quality, thereby affecting the quality of subsequent construction.
