Description

Technical Field

[0001] The utility model relates to the field of building material manufacturing and processing, and in particular to a quicklime conveying mechanism. Background Art

[0002] Quicklime is a construction raw material. When screening and processing quicklime, a conveyor belt is needed to transport it. Some conveyor belts will have a protective cover on the top to prevent the quicklime from flying into the air during transportation, damaging the environment and the health of workers. If transported for a long time, the quicklime will stick to the surface of the conveyor belt. Due to the protective cover, it is not easy to clean it. Utility Model Content

[0003] The utility model aims to provide a quicklime conveying mechanism, which has the advantage of being convenient for cleaning the lime remaining on the surface of the conveyor belt.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A quicklime conveying mechanism comprises a base, a conveyor belt is connected to the upper part of the base, the middle part of the belt surface of the conveyor belt is recessed, a protective cover is provided on the upper part of the base, mounting rods are hingedly connected to the inner walls of both sides of the protective cover, each mounting rod is slidably connected to a cylindrical connecting block, the movable end of the mounting rod is hingedly connected to a cylindrical terminal, and also comprises a scraper, the two sides of the scraper are fixedly connected to two connecting blocks respectively, the end of the scraper is provided with an edge corresponding to the recessed part of the conveyor belt, and the end is fixedly connected with bristles, the inner walls of both sides of the protective cover are provided with slide grooves respectively, The sliding groove includes a vertical waist-shaped groove, which is located directly below the hinge point between the mounting rod and the side wall of the protective cover, and an arc groove one with the hinge point between the mounting rod and the side wall of the protective cover as the center and an appropriate length as the radius; and an arc groove two with the same center as the arc groove one and the distance from the terminal to the hinge point between the mounting rod and the side wall of the protective cover as the radius. The arc groove one and the arc groove two are connected to the waist-shaped groove, and the connecting block and the terminal are respectively embedded in the arc groove one and the arc groove two, and are slidably connected to them. A driving mechanism is connected to the upper part of the interior of the protective cover, and the driving mechanism is connected to the scraper.

[0006] By adopting the above technical solution, when conveying quicklime, the scraper is in a horizontal state, and the connecting block and the terminal are respectively embedded in the arc groove one and the arc groove two. When the conveying of quicklime is stopped, the driving mechanism first drives the scraper and the mounting rod to rotate, and the moving scraper and the mounting rod rotate with the hinge point of the mounting rod and the side wall of the protective cover as the center of the circle. At the same time, the connecting block and the terminal move along the arc groove one and the arc groove two respectively. When the scraper and the mounting rod rotate to a vertical state, the connecting block and the terminal move to the vertical waist-shaped groove, and the driving mechanism continues to push the scraper so that the scraper moves downward along the mounting rod and the waist-shaped groove through the connecting block. The bristles of the scraper move to its end contact the surface of the conveyor belt and generate pressure. The conveyor belt rotates, and the conveyor belt surface and the bristles generate friction, thereby loosening the lime remaining on the belt surface. Then the conveyor belt transports the loosened quicklime to the end, and the quicklime falls from the conveyor belt.

[0007] Preferably, the driving mechanism is a screw, which is rotatably connected to the upper part of the interior of the protective cover, and a connecting rod is hinged between the screw slider and the scraper.

[0008] By adopting the above technical solution, the lead screw rotates, its slider moves, and generates a force on the scraper through the connecting rod, driving the scraper and the mounting rod to rotate along the arc groove one and the arc groove two respectively, and then the lead screw slider continues to move, driving the scraper to move downward along the mounting rod and the waist-shaped groove through the connecting rod. Similarly, the lead screw rotates in the opposite direction, and its slider returns, first driving the scraper to rise along the mounting rod and the waist-shaped groove. When the connecting block of the scraper moves and contacts the upper end of the waist-shaped groove, the lead screw slider drives the connecting block into the arc groove one, thereby driving the mounting rod and the scraper to return to their original position.

[0009] As an advantage, the screw is a bidirectional screw, the scrapers are two, the two scrapers are connected to the inner wall of the protective cover through the two slides, and the two sliders of the bidirectional screw are connected to the two scrapers through two connecting rods.

[0010] By adopting the above technical solution, the bidirectional screw rotates, and its two sliders move away from each other, and the two scrapers are driven to rotate and move downward respectively through the connecting rod. The force generated by the two scrapers on the surface of the conveyor belt is used to increase the cleaning effect.

[0011] Preferably, the scraper is a nylon plate.

[0012] By adopting the above technical solution, the durability of the scraper is increased and the damage to the conveyor belt is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
