As shown in Figures 1 to 4, a screening machine for construction includes a base 1, two support plates 1 3 are fixedly installed on the upper surface of the base 1, support plates 2 4 are fixedly installed on both sides of the upper surface of the base 1, two fixing rods 5 are fixedly installed on both sides of the upper surface of the base 1, fixed shafts 6 are fixedly installed on both sides of the upper surface of the base 1, a mounting frame 12 is fixedly installed on the upper surface of the base 1, a feed hopper 17 is fixedly connected to the top of the support plate 2 4, a screening pipe 15 is fixedly connected to the lower end of the feed funnel 17, a baffle 16 is fixedly connected to the end of the fixing rod 5 away from the base 1, and a conveying component is also included.

As a further solution of the utility model, the conveying assembly includes a rotating motor 13 fixedly mounted on the outer end of the mounting frame 12, the output shaft of the rotating motor 13 movably passes through the mounting frame 12 and is fixedly connected to a stirring rod 14, the stirring rod 14 is located in the inner part of the screening tube 15 and is fixedly installed with an auger blade 19, and the screening tube 15 is located in the inner part of the baffle 16 and is provided with evenly distributed screening holes 20.

By means of the above structure, the raw materials are screened under the rotation of the auger blade 19, and the qualified raw materials can pass through the screening holes 20 on the screening tube 15, while the remaining raw materials fall out from the opening of the screening tube 15, thereby improving the screening efficiency.

Furthermore, a retarder motor 9 is fixedly installed on the outer side of one of the support plates 3, and the output shaft of the retarder motor 9 movably passes through the support plate 3 and is fixedly connected to a transmission shaft 10, and the other end of the transmission shaft 10 is rotatably connected to the other support plate 3.

Furthermore, a tensioning roller 1 is rotatably mounted on the fixed shaft 6, and a tensioning roller 2 is fixedly mounted on the transmission shaft 10. The tensioning rollers 1 and 2 are sleeved with a conveyor belt 11, and the conveyor belt 11 is in an inclined state, and the conveyor belt 11 is slidably matched with the bottom of the blocking cover 16.

Furthermore, a screening plate 18 is connected to one side of the opening of the feed funnel 17 through a hinge, a cam 21 is fixedly connected to the end of the stirring rod 14 away from the rotating motor 13, a transmission rod 23 is fixedly installed at the bottom end of the screening plate 18, and a conical block 22 is fixedly installed at the bottom end of the transmission rod 23, a connecting plate 27 is fixedly installed on the inner wall of the feed funnel 17 near the screening plate 18, and springs 24 are fixedly installed at both ends between the connecting plate 27 and the screening plate 18, and a rubber sleeve 25 is wrapped around the outside of the spring 24, and the two ends of the rubber sleeve 25 are respectively fixedly connected to the connecting plate 27 and the screening plate 18.

The specific working method is as follows: the raw material is placed on the screening plate 18, the rotating motor 13 is started to drive the stirring rod 14 to rotate, and the cam 21 rotates synchronously. At this time, the cam 21 can produce resistance to the conical block 22 below the transmission rod 23, and generate thrust to the screening plate 18, and under the reset action of the spring 24, the screening plate 18 is vibrated up and down to pre-screen the raw material. The pre-screened qualified raw material will enter the screening tube 15 through the feeding funnel 17. Under the rotation of the stirring rod 14, the raw material rotates with the auger blade 19 on the stirring rod 14. The qualified raw material can fall onto the conveyor belt 11 through the screening hole 20 on the screening tube 15. The conveyor belt 11 then delivers the raw material to the collection box 7 through the rotation of the slow motor 9, and the remaining raw materials will fall into the waste box 8 through the opening of the screening tube 15.
