[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] The present application embodiment discloses a uniform feeding device for a wind screen cleaning machine. Figure 1 , Figure 2 , Figure 3A uniform feeding device for a wind screen cleaning machine comprises a bucket-shaped discharge port 1. In actual use, the discharge port 1 is installed on the wind screen cleaning machine so that materials can fall into the cleaning machine from the discharge port 1 for screening. A mesh plate-shaped vibration plate 2 is slidably connected to the inner wall of the discharge port 1. During the discharge process, the vibration of the vibration plate 2 makes the materials form a continuous and uniform material flow, thereby improving the cleaning effect and the stability of the equipment operation. A square groove-shaped residual material outlet 3 is opened through the side surface of the discharge port 1. A plate-shaped baffle 11 is slidably connected to the side surface of the material discharge port 1, and the baffle 11 can cover the residual material outlet 3, and a box-shaped side box 4 is fixedly connected to the side surface of the material discharge port 1 below the residual material outlet 3, and a box-shaped residual material box 5 is slidably connected to the side surface of the side box 4, so that after the material discharge is completed, the baffle 11 can be removed by the staff, so that the remaining material on the vibration plate 2 can be scraped off by the scraper 10 later, and then fall into the residual material box 5 from the residual material outlet 3 for subsequent centralized processing;

[0022] Secondly, a rectangular connecting plate 6 is fixedly connected to the side surfaces of the discharge port 1 and the side box 4, and the discharge port 1 and the side box 4 are fixedly connected to a door frame 7 through the connecting plate 6, and a rectangular sliding block 8 is slidably connected to the inner top surface of the door frame 7, and two cylinders 9 are fixedly connected to the upper surface of the sliding block 8, and the two cylinders 9 penetrate the sliding block 8 to its lower surface, and the sliding block 8 is slidably connected to a plate-shaped scraper 10 through the two cylinders 9, so that when it is necessary to clear the residual material on the vibration plate 2, the scraper 10 is lowered and contacted with the edge of the upper surface of the vibration plate 2 under the action of the cylinder 9, and then the sliding block 8 is slid, thereby driving the scraper 10 to slide, so that the residual material on the vibration plate 2 is swept to the residual material outlet 3, and falls into the residual material box 5 through the residual material outlet 3.

[0023] Reference Figure 1 A ball screw 16 is rotatably connected to the inner wall of the door frame 7, and the outer surface of the ball screw 16 is relatively screwed with the sliding block 8, and one end of the ball screw 16 passes through the door frame 7 to its outer surface, and is fixedly connected to the output end of the motor, so that the ball screw 16 can be driven to rotate by the motor, thereby driving the sliding block 8 to slide on the top surface of the door frame 7, thereby driving the scraper 10 to clean the residual material in the vibration plate 2 to avoid waste.

[0024] Reference Figure 2 and Figure 4A columnar rotating column 12 is rotatably connected to the inner wall of the discharge port 1, and two eccentric wheels 13 are fixedly connected to the outer surface of the rotating column 12, and one end of the eccentric wheel 13 passes through the discharge port 1 to its side surface, and is fixedly connected to the output end of the motor, and the outer surface of the eccentric wheel 13 is always in contact with the lower surface of the vibration plate 2. Secondly, square groove-shaped slide grooves 14 are opened on the two inner walls of the discharge port 1, and block-shaped sliders 15 are fixedly connected to the two side surfaces of the vibration plate 2, and the slider 15 slides relative to the inner wall of the slide groove 14, so that when the cleaning machine is being loaded, the rotating column 12 is driven by the motor to rotate, thereby driving the eccentric wheel 13 to rotate, so that the slider 15 slides up and down on the inner wall of the slide groove 14 to drive the vibration plate 2 to vibrate up and down, so that the material falls more evenly, stably and continuously, thereby improving the cleaning effect and the stability of equipment operation.

[0025] The implementation principle of a uniform feeding device for an air screen cleaning machine in an embodiment of the present application is as follows: in actual use, a discharge port 1 is installed on the air screen cleaning machine, and then the material is poured into the discharge port 1, and then the rotating column 12 is driven to rotate by a motor, thereby driving the eccentric wheel 13 to rotate, so that the slider 15 slides up and down on the inner wall of the slide groove 14 to drive the vibration plate 2 to vibrate up and down, so that the material falls into the cleaning machine from the small holes in the vibration plate 2 through the vibration of the vibration plate 2, and the material forms a continuous and uniform material flow through the vibration of the vibration plate 2, thereby improving the cleaning effect and the stability of the equipment operation, and after the material is discharged, the baffle 11 is removed by the staff, and then the scraper 10 is lowered and contacted with the upper surface edge of the vibration plate 2 under the action of the cylinder 9, and then the ball screw 16 is driven to rotate by the motor, thereby driving the sliding block 8 to slide on the top surface of the door frame 7, thereby driving the scraper 10 to clean the residual material in the vibration plate 2, and then fall into the residual material box 5 from the residual material outlet 3 for subsequent centralized processing to avoid waste.
