[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a screening machine that can discharge materials evenly, comprising a fixed frame 1, a screening bucket 2 is rotatably connected inside the fixed frame 1, and can screen mud and sand, a diverter frame 3 is fixedly installed on the top of the screening bucket 2, which can block large mud and sand and make it come out at the side discharge port, a motor 4 is fixedly installed on the front of the fixed frame 1, which can drive the rotating shaft 5 to rotate, a rotating shaft 5 is fixedly installed on the output end of the motor 4, which can drive the cam 6 to rotate, a cam 6 is fixedly installed on the outer wall of the rotating shaft 5, which can hit the screening bucket 2 to make the screening bucket 2 shake, a smoothing mechanism 7 is provided on the top of the screening bucket 2, which can break up the mud and sand on the top of the screening bucket 2 to facilitate screening, and a material discharge mechanism 8 is provided on the top of the screening bucket 2, which can quickly make the mud and sand at the side discharge port go out.

[0021] Specifically, the smoothing mechanism 7 includes: a turntable 71, a convex column 72, a push rod 73, a cylinder 74, a slider 75, a slide groove 76, an L-shaped rod 77, and a U-shaped rod 78. The outer wall of the rotating shaft 5 is fixedly installed with a turntable 71, which can drive the convex column 72 to rotate. The front side of the turntable 71 is fixedly installed with a convex column 72, which can drive the push rod 73 to move left and right. The outer wall of the convex column 72 is hinged with a push rod 73, which can push the cylinder 74 to move. The end of the push rod 73 away from the convex column 72 is hinged with a cylinder 74, which can drive the slider 75 to slide. The back side of the cylinder 74 is fixedly installed with a slider 75, which can drive the L-shaped rod 77 The screening bucket 2 can move left and right, and a slide groove 76 is provided on the front side of the screening bucket 2 to facilitate the sliding of the slider 75 and act as a guide wire. The back side of the slider 75 is slidably connected to the inside of the slide groove 76. An L-shaped rod 77 is fixedly installed on the top of the slider 75, which can drive the U-shaped rod 78 to move left and right. The U-shaped rod 78 is fixedly installed on the back side of the L-shaped rod 77, which can break up the mud and sand in the screening bucket 2 for easy screening. The slide groove 76, L-shaped rod 77, and U-shaped rod 78 are symmetrical with the central symmetry axis of the front side of the screening bucket 2, and are symmetrically distributed on the front and rear sides of the screening bucket 2, so that the U-shaped rod 78 can slide better at the bottom of the screening bucket 2.

[0022] Specifically, the unloading mechanism 8 includes: a moving groove 81, a moving block 82, a telescopic rod 83, and a connecting rod 84. A moving groove 81 is opened on the top of the diverter rack 3 to facilitate the sliding of the moving block 82. The moving groove 81 is internally slidably connected with the moving block 82, which can give the telescopic rod 83 a guiding effect. The left side of the moving block 82 is fixedly installed with a telescopic rod 83, which can quickly remove the mud and sand blocked by the side discharge port. The back of the telescopic rod 83 is fixedly installed on the inner wall of the screening bucket 2 for fixing. The top of the telescopic rod 83 is hinged with a connecting rod 84, which can drive the telescopic rod 83 to move. The end of the connecting rod 84 away from the telescopic rod 83 is hinged to the side of the U-shaped rod 78 for fixing.

[0023] Working principle: when the mud and sand are relatively wet and difficult to screen, the motor 4 is started to drive the shaft 5 to rotate, and the shaft 5 will drive the turntable 71 to rotate. The convex column 72 on the front of the turntable 71 will also rotate on the surface of the turntable 71, and at the same time drive the push rod 73 to move, so that the pushing cylinder 74 drives the slider 75 to move in the slide groove 76. The movement of the slider 75 can drive the L-shaped rod 77 to move, and the L-shaped rod 77 drives the U-shaped rod 78 to move. The U-shaped rod 78 moves back and forth to break up the wet mud and sand. When the screening bucket 2 shakes, it will not affect normal use, and can only drive the slider 75 to move back a little. This will not hinder normal screening and will be more conducive to screening, preventing uneven screening from having a certain impact on product quality.

[0024] When the screening machine is working, large mud and sand will come out of the upper side discharge port. If there is too much mud and sand, the discharge port may be blocked. Through the movement of the above-mentioned U-shaped rod 78, the connecting rod 84 can be driven to push the telescopic rod 83, and the telescopic rod 83 drives the moving block 82 to slide in the moving groove 81, so that the end of the telescopic rod 83 close to the discharge port can push the mud and sand blocking the discharge port, so that the material blocked in the discharge port can be discharged. In this way, the mud and sand screened on the screening bucket 2 can be quickly discharged without having to be cleaned manually, thereby improving work efficiency and saving manpower.

[0025] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
