Technical Field

[0001] This utility model belongs to the field of clay soil screening technology, specifically a clay soil screening device for manufacturing grouting fluid for coal mine drilling. Background Technology

[0002] The mine has extremely complex hydrogeological conditions. The limestone aquifer at the bottom of the coal seam is characterized by high water pressure and strong water-bearing capacity. There is a risk of water inrush during mining. It is necessary to adopt surface area water hazard control technology, which involves drilling on the surface and grouting to reinforce and modify the target layer in a certain area, transforming the target layer into a weak aquifer or water-resistant layer, thereby improving the integrity and water-resistant capacity of the rock strata at the bottom of the coal seam.

[0003] In existing coal mining operations, when grouting boreholes, the grouting materials are mainly silicate cement and clay. It is necessary to first prepare clay slurry, and then add cement to mix and prepare clay-cement slurry. In order to prepare clay slurry, a loader is needed to load soil and a high-pressure water jet is used to spray slurry. When the loader loads soil, large stones, gravel, and debris in the soil are transported to the jetting area at the same time, which makes it impossible for the jetting gun to fully dissipate the clay, resulting in a great waste of grouting materials.

[0004] Therefore, this utility model provides a clay sieving device for manufacturing grout for coal mine drilling. Utility Model Content

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1 to 4 As shown, this utility model discloses a clay screening device for producing grout for coal mine drilling. It includes a spiral feeder body 1, a screening device 2 on the side of the spiral feeder body 1, an electric auger 3 at the discharge port of the screening device 2, and a discharge port 4 at the other end of the electric auger 3. The spiral feeder body 1 can crush stones and collect clay, so that the clay can be transported into the interior of the screening device 2, so that the screening device 2 can screen out large particles. The crushed soil and sand enter the electric auger 3 and enter the slurry preparation area through the discharge port 4.

[0019] like Figures 1 to 2As shown, the main body 1 of the screw feeder includes a feeding plate 101. Two sets of feeding devices 5 are fixedly installed on the surface of the feeding plate 101. A conveying device 6 is provided at the bottom of the discharge trough opened on the surface of the feeding plate 101. The feeding device 5 includes a drive motor 102. The drive motor 102 is fixedly installed on the surface of the feeding plate 101. A rotating rod 103 is fixedly installed at the output end of the drive motor 102. A drive sprocket 104 is fixedly installed at the other end of the rotating rod 103. A chain 105 is meshed on the surface of the drive sprocket 104. A driven sprocket 106 is meshed inside the other end of the chain 105. A protective shell 107 is provided on the side of the feeding plate 101. A rotating shaft 108 is fixedly installed on the side of the driven sprocket 106. A feed plate body 109 is fixedly installed on the surface of the rotating shaft 108. The other end of the rotating shaft 108 is rotatably connected to the side of the square spacer 110. Two sets of feeding devices 5 are fixedly installed on the outside of the feeding plate 101. The drive motor 102 is fixedly installed on the outside of the feeding plate 101. 2. A rotating rod 103 is fixedly installed on the output end of the drive motor 102, and a drive sprocket 104 is fixedly installed on the other end of the rotating rod 103. The surfaces of the drive sprocket 104 and the driven sprocket 106 are connected by a chain 105. A protective shell 107 is fixedly installed on the side of the material pick-up plate 101, so that the protective shell 107 can protect the drive sprocket 104, the chain 105 and the driven sprocket 106. A rotary shaft 108 is fixedly installed on the side of the driven sprocket 106. Since there are two rotary shafts 108, the surfaces of the two rotary shafts 108 are fixedly installed with feed plate bodies 109. The two feed plate bodies 109 are a left spiral feed plate and a right spiral feed plate, respectively, so that the material can be crushed and clay can be collected. The collected clay is transported to the conveying device 6 through the discharge chute opened on the surface of the material pick-up plate 101, so that the conveying device 6 can transport it to the screening device 2 for sorting.

[0020] like Figures 1 to 4As shown, the screening device 2 includes a screening body 201. A funnel 202 is fixedly installed inside the screening body 201, and a fixing block 203 is fixedly installed inside the screening body 201. A vibrating screen 204 is fixedly installed on the top of the fixing block 203 by bolts. The fixed screen 204 can be fixed to the vibrating screen 204 by bolts, and the fixed screen 204 can be replaced with screens of different apertures according to the grouting requirements, thereby filtering large-diameter stones and pebbles. The bottom of the funnel 202 is connected to an electric auger 3. The electric auger 3 is made of high-pressure hose and contains a spiral propeller. Crushed soil and sand are drawn through the electric auger 3 and enter the slurry preparation area through the discharge port 4. At the same time, the electric auger 3 is connected to the motor shaft and the spiral spring by a screw. When the motor is started, the motor drives the spiral spring to rotate. The clay in the funnel 202 will rise along the spiral angle of the spring under the action of the rotating spring. When it reaches the discharge port 4, it can be automatically discharged due to gravity. The electric auger 3 is a new type of hose auger. It uses the motor power to drive the spiral spring to deliver the grouting material forward. The hose auger is thickened and reinforced with Oxford pipe, which has the characteristics of high temperature resistance, low temperature resistance, high pressure resistance, wear resistance, customizable length, and flexibility. The spiral spring is made of manganese steel, which has good wear resistance and toughness.

[0021] Working principle: During operation, when collecting materials, the drive motor 102 drives the rotating rod 103 to rotate. The rotating rod 103 drives the drive sprocket 104, which in turn drives the driven sprocket 106 to rotate via the chain 105. The driven sprocket 106 drives the rotating shaft 108 and the feed plate body 109 to crush the materials. The two feed plate bodies 109 are a left-hand spiral feed plate and a right-hand spiral feed plate, respectively. This crushes and collects the clay. The collected clay is transported to the conveying device 6 through the discharge chute on the surface of the receiving plate 101. The conveying device 6 then transports the clay to the screening device 2 for sorting. Materials can be screened through vibrating screen 204. Vibrating screen 204 can be replaced with different mesh sizes to filter large-sized stones and pebbles according to grouting requirements. The bottom of funnel 202 is connected to electric auger 3. Electric auger 3 is made of high-pressure hose and contains a screw propeller. Crushed soil and sand are drawn through electric auger 3 and enter the slurry preparation area through discharge port 4. At the same time, electric auger 3 is connected to motor shaft and helical spring by screw. When the motor is started, the motor drives the helical spring to rotate. The clay in funnel 202 will rise along the helical angle of the spring under the action of the rotating spring. When it reaches discharge port 4, it can be automatically discharged due to gravity.
