Description

Technical Field

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

[0002] Belt conveyors have the advantages of large conveying capacity, simple structure, easy maintenance, and standardized components. They are widely used in mining, metallurgy, coal and other industries to convey loose materials or pieced items. According to the conveying process requirements, they can be transported by a single unit, or they can be composed of multiple units or combined with other conveying equipment to form a horizontal or inclined conveying system to meet the needs of different layout types of work lines.

[0003] For example, a belt conveyor scraper device with the authorization announcement number "CN220466645U" uses the deformation force of the spring to make the scraper press against the belt, so as to avoid the situation where the scraper has insufficient contact area with the belt after severe wear, resulting in inadequate belt cleaning. At the same time, when the scraper scrapes off the firmly bonded lumps on the belt, the scraper can be retracted by compressing the spring, reducing the risk of damage to the scraper due to hard contact between the scraper and the lumps. However, when the scraper of the belt conveyor scraper device is damaged and needs to be repaired, the operator needs to turn multiple bolts to remove the scraper. Turning multiple bolts requires the operator to consume more physical strength, thereby increasing manual labor. At the same time, the scraper of the belt conveyor scraper device is fixed in height and cannot be adjusted. When it is necessary to scrape the surface of the belt conveyor with different thicknesses, the operator needs to manually select a suitable scraper for installation. Since it takes a long time to install a new scraper, the work efficiency is reduced. Utility Model Content

The output shaft of the motor 202 rotates to drive the cam 203 to rotate, thereby driving the roller 204 to move.

[0026] See attached Figure 3-4

When the turning handle 802 is rotated, the rotation of the turning handle 802 drives the gear 803 to rotate, thereby driving the protruding part of the rack 804 to slide along the inner wall of the sleeve 805, so that the rack 804 slides along the through hole processed on the second shell 801.

[0028] Working principle:

[0029] When using a scraper to clean impurities on the surface of the belt conveyor:

[0030] Scraper installation process:

[0031] The operator turns the left handle 802 clockwise, and the rotation of the handle 802 drives the gear 803 to rotate, thereby driving the protruding part of the rack 804 to slide along the inner wall of the sleeve 805, so that the rack 804 slides to the left along the through hole processed on the second shell 801, compressing the second spring 806, and at the same time, turns the right handle 802 counterclockwise to move the right rack 804 to the right, and then inserts the scraper 5 into the slide groove processed on the movable plate 4, and then the operator slowly rotates the left and right handles 802 in opposite directions, so that the surfaces of the racks 804 on both sides are tightly against the surfaces of the grooves processed on the scraper 5. When the scraper 5 needs to be repaired, the scraper 5 can be quickly removed without consuming much physical strength of the operator.

[0032] Scraper adjustment process:

[0033] Start the two motors 202 to rotate the output shafts to drive the cam 203 to rotate, thereby driving the roller 204 to move. The movement of the roller 204 drives the slide bar 205 to slide upward along the surface of the fixed column 207, and at the same time stretches the first spring 206, and the slide bar 205 slides upward along the through hole processed on the first shell 201. When the cam 203 rotates 180 degrees clockwise, the slide bar 205 moves upward to the maximum distance. The slide bar 205 moves upward and drives the movable plate 4 and the scraper 5 to move upward. When the surface of the scraper 5 is tightly fitted with the surface of the belt 7, the power supply of the motor 202 is turned off to achieve the rapid adjustment of the position of the scraper 5, thereby improving work efficiency.
