Description

Technical Field

[0001] The present application relates to the technical field of conveyors, and in particular to a scraper conveyor for efficiently conveying materials. Background Art

[0002] At present, the scraper conveyor is a continuous conveying equipment used to transport bulk materials. It is mainly composed of a scraper chain, a chute, a head, a tail and other parts. The scraper chain is driven by an electric motor to run in the chute to achieve horizontal or inclined conveying of materials. It has the characteristics of simple structure and large conveying capacity.

[0003] Scraper conveyors are used in various life scenarios, such as the transportation of mineral materials, grain, and construction materials. The materials being transported have different shapes and properties.

[0004] In actual transportation, some sticky materials will stick to the scraper during transportation, resulting in a lot of residual materials in the conveyor and affecting the next use of the scraper. Summary of the invention

[0005] In order to clean the materials sticking on the scraper in time, thereby reducing the residual materials inside the conveyor, the present application provides a scraper conveyor for efficiently conveying materials.

[0006] The present application provides a scraper conveyor for efficiently conveying materials, which adopts the following technical solutions: A scraper conveyor for efficiently conveying materials comprises a frame and a scraper, wherein the frame is provided with a scraper, a guide strip and a limit assembly, a slider is provided between the scraper and the frame, the slider is slidably arranged on the frame and reciprocates along the direction of movement of the scraper, the scraper is rotatably arranged on the slider and the rotating shaft is arranged in the horizontal direction; the guide strip is fixed on the frame, the guide strip itself comprises an inclined section and a horizontal section, the inclined section is arranged close to the scraper and is inclined upward in a direction away from the scraper, when the scraper abuts against the top of the horizontal section, the scraper rotates to a horizontal state; when the scraper rotates close to the guide strip, the top surface of the scraper is lower than the top surface of the guide strip; the limit assembly is used to limit the initial downward inclination of the scraper facing the scraper.

[0007] By adopting the above technical scheme, when the scraper runs close to the scraper blade, the outer wall of the scraper blade first abuts against the lowest inclined end of the scraper blade, and the abutting point is located close to the bottom of the scraper at this time after adjustment by the limit assembly. As the scraper blade continues to be transported, the scraper blade pushes the scraper blade to move relative to the frame until the scraper blade abuts against the guide strip. Under the action of the guide strip, the scraper blade gradually rotates from a tilted downward state to a horizontal state, that is, the end of the scraper blade abutting against the scraper blade scrapes the side wall of the scraper from bottom to top, thereby achieving the effect of cleaning the outer wall of the scraper. When the scraper blade rotates to a horizontal state, since the top surface of the scraper blade is lower than the top surface of the guide strip, the scraper can pass under the horizontal scraper without affecting the resetting of the scraper blade, which is convenient for the scraper blade to clean the subsequent scrapers, so as to achieve the effect of timely cleaning the sticky materials on the scraper blade when the scraper is in operation, thereby reducing the residual materials inside the conveyor.

[0008] Optionally, a slide groove is provided on the top of the frame, and the length direction of the slide groove is arranged along the sliding direction of the slider. The slider is slidably arranged in the slide groove. A first spring is arranged on the frame, and the first spring is located in the slide groove. One end of the first spring is fixedly connected to the slider, and the other end is fixedly connected to the inner wall of the end of the slide groove.

[0009] By adopting the above technical solution, when the scraper pushes the scraper blade and the slider to slide in the slide groove, the first spring is compressed and stores elastic potential energy. When the scraper passes under the scraper blade and no longer applies thrust to the scraper blade, the first spring releases the elastic potential energy and pushes the slider to quickly return to the initial position. This allows the scraper blade to return to the state of the scraper to be cleaned in time, ensuring that during the continuous operation of the scraper, each scraper can be cleaned in time when it passes, greatly improving the efficiency and continuity of cleaning, thereby effectively reducing the material residue inside the conveyor.

[0010] Optionally, a pressure plate and a compression spring are provided on the slider, the pressure plate is fixed on the slider, the height of the pressure plate is higher than the height of the rotation axis of the scraper and the slider, the compression spring is vertically arranged, one end of the compression spring is fixedly connected to the bottom surface of the pressure plate, and the other end abuts against the scraper.

[0011] By adopting the above technical solution, the compression spring applies a downward pressure to the scraper blade. When the scraper passes under the scraper blade and no longer applies thrust to the scraper blade, the scraper blade begins to reset. At this time, the compression spring pushes the scraper blade to an inclined downward posture, and cooperates with the gravity of the scraper blade to accelerate the adjustment of the scraper blade's posture, so that the scraper blade can return to the state of the scraper to be cleaned in time.

[0012] Optionally, the limit assembly includes a limit pin and a limit rod, the limit rod is located on the side of the slider away from the scraper blade, the limit rod is fixed on the rotating shaft of the scraper blade and the slider, and the inclination posture of the limit rod is set parallel to the inclination posture of the scraper blade; a plurality of holes are opened on the slider, the limit pin is inserted into the corresponding holes, the limit pin is located below the limit rod and abuts against the outer wall of the limit rod.

[0013] By adopting the above technical solution, the limit rod rotates synchronously with the scraper blade, and the limit pin can accurately limit the rotation range of the limit rod by inserting it into different sockets, thereby controlling the initial downward tilt of the scraper blade facing the scraper. The operator can flexibly adjust the position of the limit pin according to the actual conditions such as the viscosity of different materials and the operating speed of the scraper blade, so that the scraper blade contacts the scraper blade at the best initial angle, improve the efficiency and effect of scraping materials, ensure that the sticky materials on the scraper blade can be cleaned in time and effectively during the continuous operation of the scraper blade, and reduce the residual materials inside the conveyor.

[0014] Optionally, the connection line of the multiple sockets is semicircular and the center of the circle is passed through the rotation axis of the scraper and the slider, adjacent sockets are spaced at equal central angles, a dial is provided on the side wall of the slider away from the scraper, and all the sockets are distributed on the dial.

[0015] By adopting the above technical solution, the semicircular distribution and the equi-center angle intervals of the sockets, combined with the dial, allow the operator to intuitively and accurately adjust the position of the limit pin. The dial provides a clear reference for adjustment. The operator can accurately insert the limit pin into the corresponding socket according to the scale based on the material characteristics and actual cleaning needs, thereby accurately controlling the initial tilt angle of the scraper. This precise adjustment method enables the scraper to better adapt to different working conditions, and more efficiently clean the sticky materials on the scraper when the scraper is in continuous operation, further reducing the material residue inside the conveyor.

[0016] Optionally, a water supply channel is provided on the scraper blade, and the outlet end of the water supply channel is arranged toward the scraper. A water supply pipe and a tensioning assembly are provided on the slider. One end of the water supply pipe passes through the slider and extends into the water supply channel. The water supply pipe is slidably connected to the slider, and the end of the water supply pipe is fixedly connected to the scraper blade. The end of the water supply pipe away from the scraper blade is used to connect to an external water pump; the tensioning assembly is used to tension the water supply pipe between the slider and the scraper blade.

[0017] By adopting the above technical solution, the water supply pipe introduces water from the external water pump into the water supply channel, and the water is sprayed from the outlet end of the water supply channel to the scraper to wet the sticky material on the scraper. The viscosity of the wetted material is reduced, making it easier to be scraped off by the scraper, thereby improving the cleaning effect of the scraper. The tensioning component can keep the water supply pipe in a tensioned state during the movement of the slider and the scraper, avoiding entanglement and bending of the water supply pipe, and ensuring a stable supply of water. In this way, when the scraper continues to operate, the water supply channel can continue to provide assistance to the scraper to clean the material, effectively reducing the residual material inside the conveyor.

[0018] Optionally, the tensioning assembly includes a second spring and a clamp, which is embedded and fixed on the outer wall of the water supply pipe. The clamp is located on the side of the slider away from the scraper. The second spring ring is sleeved on the water supply pipe. One end of the second spring abuts against the outer wall of the slider, and the other end abuts against the clamp, and the second spring is in a compressed state.

[0019] By adopting the above technical solution, during the sliding of the slider and the rotation of the scraper, the second spring releases its elastic force to push the clamp to keep the water supply pipe taut. This automatic adjustment of the tension ensures that the water supply pipe will not become loose or tangled during the operation of the equipment, and ensures that water can flow smoothly from the water supply channel to the scraper.

[0020] Optionally, the scraper blade is provided with a sweeping assembly, which includes a cross bar, a rotating drum, a sweeping block, a vertical bar and a connecting rod; the rotating drum is rotatably arranged on the scraper blade and the rotating axis is its own central axis, the cross bar is fixed on the scraper blade and is arranged parallel to the central axis of the rotating drum, a guide groove is provided on the rotating drum, and the guide groove is opened in a wave shape along the circumferential outer wall of the rotating drum, the cross bar passes through the sweeping block, and the sweeping block slides back and forth along the length direction of the cross bar; one end of the sweeping block is inserted into the guide groove and slides along the length direction of the guide groove; one end of the connecting rod is fixedly connected to the sweeping block, and the other end is hinged to the vertical bar ball, and the vertical bar slides against the outer wall of the scraper.

[0021] By adopting the above technical solution, the drum rotates, and the wavy guide groove on the drum drives the sweeping block to slide back and forth along the crossbar. The sweeping block drives the vertical bar to slide on the outer wall of the scraper through the connecting rod. The sliding of the vertical bar further cleans the material remaining on the scraper blade and the outer wall of the scraper after the scraper blade scrapes it off. During the continuous operation of the scraper, the sweeping assembly works with the scraper blade to clean the inside of the conveyor from different directions and angles, realizing all-round cleaning of the material inside the conveyor and effectively reducing the material residue in every corner of the conveyor.

[0022] Optionally, the connecting rod is an elastic telescopic rod.

[0023] By adopting the above technical solution, the elastic telescopic rod can automatically adjust the length according to the different situations encountered by the vertical bar during the cleaning process. When the vertical bar encounters a part with thick material accumulation or uneven surface, the elastic telescopic rod can be extended or shortened, so that the vertical bar always maintains a good contact pressure with the outer wall of the scraper to ensure the cleaning effect.

[0024] Optionally, a motor is fixed on the scraper, and an output end of the motor is fixedly connected to the center of the end of the rotating drum.

[0025] By adopting the above technical solution, the motor provides stable and controllable power for the drum.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting the scraper, guide strips and limit assembly, the scraper can scrape the side wall of the scraper from bottom to top when the scraper is in continuous operation, and the materials stuck on the scraper can be cleaned in time. The scraper can pass under the scraper in a horizontal state, which is convenient for the scraper to reset and clean the subsequent scrapers, effectively reducing the residual materials inside the conveyor; 2.
