DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] See also Figure 1-Figure 2 As shown, the utility model provides a technical solution: a screening device for lightweight mortar, comprising a box body 1, a feed port 2, a vibrating screen 3 and a discharge port 4, a moving component is installed on the top of the inner wall of the box body 1, a cleaning component is installed above the vibrating screen 3, and a collecting component is installed below the vibrating screen 3;

[0025] Furthermore, the outer side of the feed port 2 is rotatably connected with a guide groove 5, and both sides of the guide groove 5 are slidably connected with a connecting rod 6, and the other end of the connecting rod 6 is fixedly connected to the output shaft end of the first motor 7. The connecting rod 6 is controlled to rotate by the first motor 7, so that the guide groove 5 is turned outward to open the feed port 2. The baffles on both sides of the guide groove 5 play a role in guiding flow;

[0026] Furthermore, the moving assembly includes a slide groove 8, a nut seat 9, a screw 10, a third motor 11 and an electric push rod 12. The slide groove 8 is installed on the top of the box body 1, and the inner side of the slide groove 8 is slidably connected to the nut seat 9. The internal thread of the nut seat 9 is connected to the screw 10, and the third motor 11 is installed at one end of the screw 10. The electric push rod 12 is installed at the bottom of the nut seat 9. The piston rod of the electric push rod 12 is fixed at the midpoint of the mounting plate 13. Through the cooperation of the screw 10 and the nut seat 9, the cleaning assembly is driven to move along the direction of the vibrating screen 3, and then, the gap between the cleaning assembly and the vibrating screen 3 is adjusted by the electric push rod 12.

[0027] See also Figure 1-Figure 2 As shown, the cleaning assembly includes a mounting plate 13, a fourth motor 14, a second connecting rod 15, a telescopic rod 16 and an extrusion plate 17. The fourth motor 14 is symmetrically mounted on the surface of the mounting plate 13, and the second connecting rod 15 is mounted on the output shaft end of the fourth motor 14. The extrusion plate 17 is mounted on the bottom of the mounting plate 13 through the telescopic rod 16. The second connecting rod 15 penetrates the mounting plate 13 and contacts the surface of the extrusion plate 17. The second connecting rod 15 is driven by the fourth motor 14 to synchronously perform pendulum motion, and the gap between the mounting plate 13 and the extrusion plate 17 is continuously adjusted. When the gap is enlarged, the extrusion plate 17 quickly squeezes the surface of the vibration screen 3 downward to clean up the stone particles embedded in the vibration screen 3.

[0028] It should be noted that: the spring inside the telescopic rod 16 always ensures the connection between the sleeve rod and the sleeve;

[0029] Furthermore, the inclination angles of the mounting plate 13, the extrusion plate 17 and the vibration screen 3 are matched, so that the extrusion force generated by the extrusion plate 17 is completely perpendicular to the vibration screen 3, thereby better cleaning the embedded particles.

[0030] See also Figure 1-Figure 2 As shown, the collecting assembly includes a second motor 18, a cable 19, a cloth roll 20 and a collecting frame 21. The second motor 18 is symmetrically installed below the feed port 2. The output shaft of the second motor 18 is wound with a cable 19. The cable 19 runs through the box body 1 and is fixedly connected to one end of the cloth roll 20. The end of the cloth roll 20 away from the second motor 18 is installed below the discharge port 4 through a spring. A collecting frame 21 is installed below the cloth roll 20. The second motor 18 pulls the cloth roll 20 out through the cable 19 and lays it flat under the vibrating screen 3, so that the cleaned particles fall on the surface of the cloth roll 20. Then, the cloth roll 20 is loosened, so that the cleaned particles move to the inside of the collecting frame 21.

[0031] Furthermore, the width of the cloth roll 20 matches the width of the box body 1 to prevent the cleaned particles from falling into the box body 1 .

[0032] Furthermore, the collecting frame 21 and the box body 1 are movably connected, so that the collecting frame 21 can be easily removed and the cleaned particles can be dumped out.

[0033] Working principle:

[0034] The raw material is input into the box body 1 through the guide groove 5, and the particles that do not meet the requirements are screened out through the vibrating screen 3, and then flow out of the box body 1 through the discharge port 4;

[0035] When particles that do not meet the requirements are embedded in the vibrating screen 3 and cannot be cleaned by the vibration of the vibrating screen 3 itself, first, the third motor 11 drives the lead screw 10 to rotate, so that the nut seat 9 moves along the direction of the slide groove 8, and then the electric push rod 12 extends, so that the extrusion plate 17 fits the surface of the vibrating screen 3, and at the same time, the second motor 18 reels in the cable 19, and spreads the roll cloth 20 flat under the vibrating screen 3, then, the fourth motor 14 starts, driving the second connecting rod 15 to do a pendulum motion, adjusting the gap between the extrusion plate 17 and the mounting plate 13, so that the extrusion plate 17 slaps the vibrating screen 3 with force so that the particles that do not meet the requirements fall on the surface of the roll cloth 20, and finally, the second motor 18 relaxes the cable 19, the roll cloth 20 is recovered, and the particles on the surface of the roll cloth 20 are collected into the inside of the collection frame 21.

[0036] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
