Chute full-section scraper structure

Abstract

The utility model discloses a chute full-section scraper plate structure which comprises a first scraper plate and a second scraper plate, two ends of the first scraper plate are connected with an open type connecting ring, the second scraper plate is installed on the first scraper plate and wraps the first scraper plate, and the second scraper plate is in large-area contact with the open type connecting ring through extending ends on two sides of the scraper plate. When materials are conveyed, due to the fact that the contact area of the second scraper blade and the end face of the chute is increased, and then the second scraper blade and the mining round-link chain are connected together for use, as the contact area of the second scraper blade and the open type connecting ring is increased, namely the section of the chute during transportation is increased, the conveying capacity is improved, and particularly an ideal conveying effect can be achieved during thinner transportation. The scrapers are arranged to be of a detachable structure, the second scrapers are buckled and fixed to the first scrapers, due to the fact that the second scrapers make contact with conveyed materials, when the second scrapers are damaged, only the second scrapers need to be detached and replaced, and resources are saved compared with traditional replacement.

Description

Technical Field

[0001] This utility model relates to the field of scraper technology, specifically to a full-section scraper structure for a chute. Background Technology

[0002] In the coal industry, after the tunneling machine cuts the coal, the transport of coal involves a star wheel scraping the coal into the chute of the first conveyor. The scraper chain in the chute, driven by a hydraulic motor, transports the coal, rock, and other materials to the tail of the machine, where they are then transferred to the second conveyor or mine cars for further transport. The structural design of the scrapers is crucial during the coal transport process on the first conveyor.

[0003] Traditional scraper chains (such as) Figure 1-2 (As shown) The structure consists of a scraper 1, a mining circular link chain 5 or 6, and an open connecting ring 7, all connected by bolts 2, nuts 3, and washers 4. The mining circular link chain 5 or 6 and the open connecting ring 7 form a scraper chain, where the shape of the scraper plays a significant role in the conveying capacity. Traditional scraper systems suffer from large coal leakage and low efficiency, especially during the transport of thin materials, which leak from the gap between the chute and the scraper. Furthermore, since the scrapers are all integrated mechanisms, when a scraper is damaged, the entire scraper needs to be replaced, requiring the scraper to be removed from the open connecting ring, which is both inconvenient and time-consuming, thus affecting work efficiency. Therefore, a full-section scraper structure for the chute is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a full-section scraper structure for a chute to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a full-section scraper structure for a chute, comprising a first scraper and a second scraper, wherein the two ends of the first scraper are connected to an open connecting ring, the second scraper is mounted on the first scraper and covers it, and the first scraper is provided with a positioning plate that limits the installation position of the second scraper.

[0006] The two ends of the second scraper extend outward to form extended ends, which are used to cover the upper end of the open connecting ring and increase the contact area between the second scraper and the end face of the chute.

[0007] Preferably, the bottom of the second scraper is recessed inward, and during installation, the second scraper is snapped together and fixed to the first scraper with bolts, and is limited by a positioning plate.

[0008] Preferably, the second scraper is provided with an opening communicating with the recess of the second scraper, in order to reduce the weight of the second scraper.

[0009] Preferably, the top surface of the extended end is lower than the top surface of the second scraper to fit the chute.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: A full-section scraper structure for a chute increases the contact area between the extended ends of the scraper on both sides and the open-type connecting ring, thereby increasing the contact area between the second scraper and the end face of the chute. When used with a mining circular link chain or connector, the increased contact area between the second scraper and the open-type connecting ring during material transport improves the conveying capacity, especially for thin materials, achieving ideal conveying results. By setting the scraper to a detachable structure, the second scraper is snapped and fixed to the first scraper, protecting the first scraper. The first scraper is connected to the open-type connecting ring. Since the second scraper is in contact with the conveyed material, when damage occurs, it can be easily removed and replaced, saving resources compared to traditional replacement methods. The openings on the second scraper reduce its weight and decrease the sag between the circular link chains. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2 The structure consists of a traditional scraper 1, a vertically arranged mining circular chain 5, a horizontally arranged mining circular chain 6, and an open connecting ring 7, which are connected by bolts 2, nuts 3, and washers 4, and their state within the chute.

[0021] Please see Figure 3-7 This utility model provides a technical solution: a full-section scraper structure for a chute, including a first scraper 8 and a second scraper 9. The two ends of the first scraper 8 are connected to an open connecting ring 7. The second scraper 9 is installed on the first scraper 8 and covers it. A positioning plate 10 is provided on the first scraper 8 to limit the installation position of the second scraper 9.

[0022] The first scraper 8 is composed of a mining circular chain 5 or 6, an open connecting ring 7, and a bolt 2, nut 3, and washer 4, which is the same as the traditional connection method.

[0023] The two ends of the second scraper 9 extend outward to form extension ends 12, which are used to cover the upper end of the open connecting ring 7, thereby increasing the contact area between the second scraper 9 and the end face of the chute.

[0024] The bottom of the second scraper 9 is recessed inward. During installation, the second scraper 9 is snapped together and fixed to the first scraper 8 with bolts, and is limited by the positioning plate 10.

[0025] The second scraper 9 is provided with an opening 11 that communicates with the recess of the second scraper 9, in order to reduce the weight of the second scraper 9.

[0026] The top surface of the extension end 12 is lower than the top surface of the second scraper 9, and is used to fit the chute.

[0027] Working principle: By extending the ends 12 on both sides of the second scraper 9, the contact area between the second scraper 9 and the end face of the chute is increased. When conveying materials, the increased contact area between the second scraper 9 and the open connecting ring 7 increases the cross-section of the chute, thereby improving the conveying capacity. This is especially true for conveying thin materials, where the ideal conveying effect can be achieved. When the scraper needs to be replaced, since the second scraper 9 protects the first scraper 8 and is detachably connected, the damaged second scraper 9 can simply be removed from the first scraper 8 and replaced.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
