Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor head cleaning, and specifically discloses a belt conveyor head cleaning device. Background Art

[0002] At present, the belt conveyors of the bulk cargo loading and unloading system of the port mostly use various forms of cleaners to clean the surface of the belt conveyor to reduce the material leakage during the return process of the belt conveyor after passing through the head redirection roller. Practice has proved that it is difficult for a single type of cleaner to clean the material attached to the surface of the belt when the material conveyed by the belt conveyor has high viscosity and high water content, which often causes a large range of leakage. When the leakage is large, it can even hinder the normal operation of the return roller or redirection roller, causing hidden dangers to the safe operation of the equipment. If you blindly install a cleaner or increase the pre-tightening force of the cleaner on the belt in pursuit of a better cleaning effect, it will cause rapid wear of the belt and affect the service life of the belt. In a certain sense, the cleaning effect of the traditional cleaner during use and the service life of the belt are contradictory. The better the cleaning effect, the shorter the service life of the belt.

[0003] The area behind the redirecting roller of the belt conveyor head is the main part of material spillage. Due to the structural strength requirements, the surrounding roller fixing frame is thick and the space is small, which is time-consuming and laborious to clean. Since the roller is a rotating part and is close to the transfer funnel at the head, a guardrail or protective net is installed here for safety protection. If you want to clean the accumulated material here, you need to remove these protective devices, and you must restore them after cleaning, which has low operating efficiency. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a belt conveyor head cleaning device to solve the problems that timely cleaning of material leakage in the area behind the belt conveyor head redirection roller is difficult, is restricted by the small space on site, and has low cleaning efficiency and heavy personnel burden.

[0005] To achieve the above purpose, the technical solution of the utility model is:

[0006] A cleaning device for the head of a belt conveyor includes a roller, a belt is wound around the roller, a slide plate is arranged below the roller, a material receiving hopper is connected to the end of the slide plate, and brackets are arranged on both sides below the belt; the distance between the brackets is greater than the width of the belt; a cylinder body of an oil cylinder is hinged on the bracket; and a scraper plate is hinged on the piston rod of the oil cylinder. The oil cylinder drives the scraper plate to clean the materials spilled on the slide plate in time, which reduces the cleaning difficulty, facilitates the operation in a narrow space, improves the cleaning efficiency, and reduces the burden of manual operation.

[0007] Preferably, the scraper 1 includes a rectangular parallelepiped 1; the bottom surface of the rectangular parallelepiped 1 is fixedly provided with an arc plate 1; the side surface of the rectangular parallelepiped 1 is provided with an articulated seat; the piston rod of the oil cylinder is hinged in the articulated seat. When pushing materials, the front end surface of the arc plate 1 is conveniently used to push materials; when the oil cylinder drives the arc plate 1 to retract, the rear end surface of the arc plate 1 and the articulated setting are used to reduce the materials brought back by the scraper 1 when the oil cylinder piston rod is retracted, thereby ensuring the cleaning efficiency.

[0008] Preferably, both sides of the rectangular parallelepiped are provided with limit pieces; a limit plate is provided above the top surface of the bracket in parallel with the limit piece; and a guide plate is hinged at the end of the limit plate. When pushing materials, the limit piece moves along the limit plate and the top surface of the bracket, pushing the guide plate to rotate around the hinge, and the limit piece moves to the front side of the guide plate; when the cylinder piston rod is retracted, the guide plate falls down due to gravity and contacts the top surface of the bracket, and the limit piece moves along the guide plate to the top of the limit plate, driving the scraper plate to move upward, further reducing the material brought back by the scraper plate when the cylinder piston rod is retracted, thereby ensuring the cleaning efficiency.

[0009] Preferably, the bracket is provided with a front limit switch and a rear limit switch, so as to conveniently control the extension and retraction of the piston rod of the oil cylinder.

[0010] Preferably, a second scraper is arranged in front of the first scraper through a connecting rod; the second scraper includes a second cuboid and a second arc-shaped plate fixedly arranged on the bottom surface of the second cuboid; one end of the connecting rod is fixedly arranged on the front side surface of the first cuboid, and the other end is fixedly arranged on the rear side surface of the second cuboid; and limiters are arranged on both side surfaces of the second cuboid. The amount of material cleaned by a single action of the oil cylinder can be increased, and the cleaning efficiency can be improved.

[0011] Preferably, the limiting member is a rotatably arranged roller.

[0012] Preferably, the limiter comprises a bottom plate; an inclined plate is fixedly arranged at one end of the bottom plate; a vertical plate is arranged at the end of the inclined plate; and a folding plate is fixedly arranged at the other end of the bottom plate. The inclined plate is arranged to facilitate translation along the guide plate. The vertical plate is arranged to facilitate contact with the rear limit switch. The folding plate is arranged to facilitate contact with the front limit switch.

[0013] Preferably, the oil cylinder is connected to a reversing valve through a pipeline; the oil return port of the reversing valve is connected to an oil tank; the oil inlet of the reversing valve is connected to a hydraulic pump; and the oil inlet of the hydraulic pump is connected to the oil tank.

[0014] The beneficial effects of the utility model are:

[0015] 1. Use the oil cylinder to drive the scraper to clean up the materials spilled onto the slide in time, which reduces the difficulty of cleaning, facilitates operation in narrow spaces, improves cleaning efficiency, and reduces the burden of manual operation.

[0016] 2. When pushing materials, the limiter moves horizontally along the limiter plate and the top surface of the bracket, pushing the guide plate to rotate around the hinge, and the limiter moves horizontally to the front side of the guide plate; when the cylinder piston rod is retracted, the guide plate falls down due to gravity and contacts the top surface of the bracket, and the limiter moves horizontally along the guide plate to above the limiter plate, driving the scraper to move upward, further reducing the material brought back by the scraper when the cylinder piston rod is retracted, thereby ensuring cleaning efficiency.

[0017] 3. The setting of scraper 2 can increase the amount of material cleaned by a single action of the cylinder and improve the cleaning efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
