Description

Technical Field

[0001] The utility model relates to the field of discharging scrapers, in particular to a belt discharging scraper device. Background Art

[0002] The belt is the main carrier for transporting materials on the belt conveyor. When the material falls on the belt for transportation, the material will pass through the head roller and the chute to enter the next process. After the material is discharged, a small amount of residual impurities will stick to the working surface of the belt. As the belt is driven downward, the impurities will fall under the belt conveyor, but some impurities will adhere to the surface of the belt. At this time, a scraper is needed to scrape the material for cleaning.

[0003] However, most of the existing scrapers are set below the belt or above one side of the belt, and the size of the scraper is fixed. When facing belts of different widths, the length of the scraper cannot be adjusted, which limits the cleaning range of the scraper and is not conducive to the scraper to fully scrape and clean the belt surface.

[0004] Therefore, it is necessary to invent a belt discharging scraper device. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a belt discharging scraper device, comprising a conveying belt, a fixed frame is provided at one end of the conveying belt, a collecting box is installed on one side of the lower end of the fixed frame, a positioning plate is installed on one side of the upper end of the fixed frame, a first tooth plate and a second tooth plate are symmetrically provided at the lower end of the positioning plate, a gear is installed in the middle of the lower end of the positioning plate, the gear is located between the first tooth plate and the second tooth plate, and scrapers are installed at the lower ends of the first tooth plate and the second tooth plate.

[0007] Based on the above characteristics: when the length of the scraper is consistent with the width of the conveyor belt, the first tooth plate and the second tooth plate can be driven by the gear to move toward each other so that the two ends of the first tooth plate and the second tooth plate are aligned. At this time, the two scrapers at the lower ends of the first tooth plate and the second tooth plate will also be in an aligned state, which is convenient for the scraper to scrape and clean the surface of the conveyor belt. When the width of the conveyor belt is greater than the length of the scraper, the gear can be reversed so that the gear drives the first tooth plate and the second tooth plate to move toward each other. At this time, the first tooth plate and the second tooth plate will drive the two scrapers below to move so that the two scrapers become staggered until one side of the two scrapers is located on both sides of the conveyor belt. The length of the scraper can be adjusted for conveyor belts of different widths.

[0008] Preferably, limiting support plates are symmetrically installed on both sides of the lower end of the positioning plate, and guide grooves are symmetrically opened on the lower end surface of the positioning plate.

[0009] Based on the above characteristics: the limit support plate can be limited and supported on one side of the first tooth plate and the second tooth plate, and the guide groove can limit and guide the first tooth plate and the second tooth plate, so as to facilitate the parallel movement of the first tooth plate and the second tooth plate, and at the same time avoid the first tooth plate and the second tooth plate from being offset and falling during the movement.

[0010] Preferably, the first tooth plate and the second tooth plate have the same structure, and the first tooth plate and the second tooth plate are arranged opposite to each other in an alternating manner.

[0011] Based on the above features: it is convenient for the first tooth plate and the second tooth plate to drive the two scrapers below to move toward each other, so that the length between the two scrapers can be adjusted.

[0013] Based on the above features: the scraper is installed inside the T-shaped slot, and the second tooth plate and the first tooth plate are slidably connected by a guide sliding block and a guide sliding groove.

[0014] Preferably, a through slot is provided in the middle of the lug, an anti-dropout plug plate is inserted in the middle of the through slot, and a baffle is fixedly mounted on the upper end of the anti-dropout plug plate.

[0015] Based on the above features: when the scraper is inserted into the T-shaped slot, the anti-dropping plug plate can be inserted into the inner side of the through slot to prevent the scraper from being dropped out after insertion.

[0016] Preferably, a damping shaft is installed in the middle of the gear, a knob is installed on the upper end of the damping shaft, and the knob is located at the upper end of the outer portion of the positioning plate.

[0017] Based on the above features: personnel can drive the gear to adjust forward and reverse rotation through the knob and the damping shaft at the outer end, and the two sides of the gear are meshed and connected with the first gear plate and the second gear plate, so that the gear can drive the first gear plate and the second gear plate to move in opposite directions.

[0018] Preferably, a T-shaped plug is fixedly mounted on the upper end of the scraper.

[0019] Based on the above features: the scraper is inserted into the T-shaped slot using a T-shaped plug, which not only facilitates the straight-line insertion and removal of the scraper, but also prevents the scraper from deviating to the left and right and falling off.

[0020] The beneficial effects of the utility model are:

[0021] 1. The length of the scraper can be adjusted according to the width of the conveyor belt. When the length of the scraper is consistent with the width of the conveyor belt, the two scrapers at the lower ends of the first tooth plate and the second tooth plate will be in an aligned state, which is convenient for the scraper to scrape and clean the surface of the conveyor belt. When the width of the conveyor belt is greater than the length of the scraper, the gear can be driven to rotate by the knob and the damping shaft. At this time, the gear will drive the first tooth plate and the second tooth plate to move towards each other, and the first tooth plate and the second tooth plate will drive the two scrapers below to move, so that the two scrapers become staggered until one side of the two scrapers is located on both sides of the conveyor belt. In this way, the length of the scraper can be adjusted for conveyor belts of different widths.

[0022] 2. The scraper is plugged into the T-slot by a T-plug, which facilitates the scraper to be disassembled and assembled from the lower ends of the first tooth plate and the second tooth plate. When the T-plug is plugged into the T-slot, the anti-dropout plug can be plugged into the inner side of the through slot, so that the anti-dropout plug can limit and block both sides of the T-plug to prevent the scraper from being detached after insertion, and the upper end of the anti-dropout plug is limited by a baffle to prevent the anti-dropout plug from falling down from the inside of the through slot. When the scraper needs to be removed and replaced, it is only necessary to directly pull the dropout plug to lift the anti-dropout plug upwards and detach it from the through slot, and finally pull the scraper out of the T-slot, which is simple and convenient.
