Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of sand and gravel sorting, and more specifically to an all-in-one sand and gravel sorting and cleaning machine for civil engineering. Background Art
[0002] Sand and gravel refer to a loose mixture of sand and crushed stone. In geology, mineral or rock particles with a particle size of 0.074-2mm are called sand, and those with a particle size greater than 2mm are called gravel or angular cobbles. If the crushed stone in the sand and gravel is mostly gravel, it is called sand and gravel. In daily life, some people also call sandstone sand and gravel. The structures of different sand and gravel are quite different. Some have uniform particle size, some are of different sizes, some have good roundness in the debris, and some have sharp edges and corners in the debris. Sand and gravel are loose materials, but their particles are generally hard, and in the surface environment, their chemical properties are stable. For sandstone, its weathering resistance is generally strong, especially silicified quartz sandstone, its hardness exceeds that of granite. Since different buildings require the use of sand and gravel of different particle sizes, screens are needed to sort them.
[0003] However, the existing sand and gravel sorting method is generally to manually beat the sand and gravel on the screen with tools such as shovels, so that the sand and gravel with smaller particle sizes pass through the screen, and the sand and gravel with larger particle sizes are filtered on the other side of the screen. Such operation is not only time-consuming and labor-intensive, but also has an insignificant effect on the sorting of sand and gravel. In addition, the existing sand and gravel contain a large amount of soil particles, and a large amount of fine sand is mixed in the soil particles, but the existing screen cannot separate the soil particles, resulting in the sand and gravel after screening still containing a large amount of soil particles, which in turn affects the subsequent use of the sand and gravel.

[0039] The working principle of the present invention is as follows: first, when in use, the sand and gravel to be sorted are first added into the screening inner cavity 402 opened by the drum screen 4, and then the servo motor 10 is turned on so that the servo motor 10 drives the pinion 11 to rotate, and at this time the pinion 11 drives the mutually meshing transmission gear 5 to rotate, and then the transmission gear 5 drives the drum screen 4 to rotate inside the support plate 2, and at this time the rotation of the drum screen 4 causes the sand and gravel in the screening inner cavity 402 to be stirred, and at this time the smaller sand and gravel falls to the unloading slide through the screen holes 403 At the top of the plate 3, the pressure pump 7 and the water pump 18 are turned on at the same time, so that the pressure pump 7 sprays gas to the drum screen 4 through the air pressure spray gun, so that the holes on the surface of the drum screen 4 are dredged to prevent blockage, and then the turned-on water pump 18 sends the water source inside the water storage cavity 101 into the spray pipe 16 through the water supply pipe 19, and then sprays the water source to the sand and gravel selected on the top of the lower slide plate 3 through the spray head 17, so that the water source is washed by the sand and gravel and enters the cleaning cleaning 1201 opened in the cleaning box 12, and then passes through the cleaning gauze 15 The sand and gravel are blocked, and then the micro motor 13 is turned on so that the micro motor 13 drives the transmission screw 1301 to rotate inside the connection block 1202 opened on the top of the cleaning box 12. At this time, the transmission screw 1301 rotates to drive the anti-blocking push rod 14 to move. At this time, the connector 1401 drives the rectangular push plate 1403 to move the sand and gravel on the top of the cleaning gauze 15, so that the sewage entering the cleaning box 1201 with the sand and gravel enters the internal position of the sedimentation box 20, and then the spiral feeding rack 404 opened on the inner wall of the screening cavity 402 is used to feed the sand and gravel. When the stone is sorted, the large particles of sand and gravel squeeze and collide with the soil particles, so that the soil particles are broken and the fine sand and gravel inside fall to the top of the unloading slide plate 3, and then the large particles of sand and gravel are driven by the screen holes 403 and discharged from the other end of the drum screen 4. After the sorting is completed, the sewage inside the cleaning box 12 is allowed to stand and the sludge is settled at the bottom of the sedimentation box 20, and then the cleaner water source on the upper layer is discharged and recycled through the drain pipe 1203, and then the handle 21 is held to clean and remove the sludge inside the sedimentation box 20.
