Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material conveying scraper conveyors, and specifically relates to a material conveying scraper conveyor with a self-cleaning structure. Background Technique
[0002] In the current technical field of material conveying, especially in the scenario of long-distance or large-scale conveying of materials (such as wheat, coal, ore, etc.) using a scraper conveyor, as an efficient and continuous conveying device, the scraper conveyor is widely used in various industrial production lines. However, in the design and operation of the scraper conveyor, a common problem is the spatial dead angles formed between the head driving shaft and the tail driven shaft and the machine shell. Due to the limitations of the structural design, these dead angles are difficult to be directly touched by the scraper chain, resulting in the inevitable accumulation of some materials in these difficult-to-clean areas during the continuous material conveying process.
[0003] These accumulated materials not only occupy valuable space, but more importantly, they are prone to getting damp, fermenting, and even generating corrosive substances after long-term static placement, causing erosion to the metal components of the scraper conveyor (such as bearings, chains, shells, etc.), thereby accelerating the aging and damage of the equipment, significantly reducing the overall service life and maintenance cycle of the equipment. In addition, due to the usually hidden and narrow space of these dead angle positions, the traditional manual cleaning method is not only inefficient, labor-intensive, but also increases the safety risk of the operators. At the same time, the high labor cost and downtime also pose a great challenge to the production efficiency and economic benefits of the enterprise. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] The following description is essentially exemplary only and is not intended to limit the present disclosure, application, and uses. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. Each drawing only schematically shows the concept and principle of the embodiments of the present disclosure, and does not necessarily show the specific dimensions and their ratios of the embodiments of the present disclosure. In a specific part of a specific drawing, the relevant details or structures of the embodiments of the present disclosure may be illustrated in an exaggerated manner.
[0024] Please refer to Figures 1-5 , an embodiment provided by the utility model:
[0025] A material conveying scraper with a self-cleaning structure, including a conveying scraper main body 1. A plurality of support rods 2 are fixedly installed at the bottom end of the conveying scraper main body 1. A scraper head 4 and a scraper tail 5 are arranged at both ends of the conveying scraper main body 1, and a conical hopper 9 is communicated with the bottom ends of the scraper head 4 and the scraper tail 5. Two groups of self-cleaning structures are arranged at the top end of the conveying scraper main body 1. The self-cleaning structure includes a material accumulation collection barrel 6. A plurality of support columns 7 are fixedly installed on the outer surface of the material accumulation collection barrel 6, and the plurality of support columns 7 are fixedly connected with the top end of the conveying scraper main body 1. A connecting pipe 8 is connected to the outer surface of the material accumulation collection barrel 6, and one end of the connecting pipe 8 is connected to the conical hopper 9. A filter cloth bag 711 is arranged on the inner wall of the material accumulation collection barrel 6, and a negative pressure fan is arranged at the top end of the material accumulation collection barrel 6. The negative pressure fan includes a housing 411, and the housing 411 is installed at the top end of the material accumulation collection barrel 6. A mounting plate 413 is fixedly installed on the inner wall of the housing 411, and a motor 412 is fixedly installed on one side of the mounting plate 413. One end of the motor 412 is connected with a shaft rod 414, and a plurality of fan blades 415 are fixedly installed on the outer surface of the shaft rod 414. A discharge pipe 511 is connected to the bottom end of the material accumulation collection barrel 6, and the discharge pipe 511 is communicated with the outer surface of the conveying scraper main body 1. An electronic valve 512 is arranged on the outer surface of the discharge pipe 511.
[0026] Further, a reinforcing rod 3 is fixedly installed between the plurality of support rods 2. The reinforcing rod 3 significantly enhances the structural stability between the support rods 2 and improves the load-bearing capacity and anti-deformation ability of the entire scraper main body 1.
[0027] Further, a level switch 611 is arranged at the upper part of the inner wall of the material accumulation collection barrel 6. When the material reaches the preset height, the level switch 611 can quickly cut off the power supply of the negative pressure fan to prevent the material from overflowing. This instant response helps to maintain the precise control and efficient operation of the system.
[0028] Further, a plurality of fixing rings 311 are fixedly installed on the outer surface of the connecting pipe 8, and one end of the plurality of fixing rings 311 is connected with a fixing rod 312. One end of the fixing rod 312 is fixedly connected with the outer surface of the conveying scraper main body 1. Through the fixing rings 311 and the fixing rods 312, the connecting pipe 8 is firmly installed on the conveying scraper main body 1, effectively preventing the connection from loosening or falling off due to vibration or external force, and ensuring the continuity and stability of material transmission.
[0029] Further, a plurality of U-shaped connecting frames 212 are fixedly installed on the outer surface of the bottom end of the material accumulation collection barrel 6, and a vibration motor 211 is fixedly installed on the outer surface of the plurality of U-shaped connecting frames 212. The vibration motor 211 can provide additional vibration force during the cleaning process to help the material in the material accumulation collection barrel 6 be discharged faster and more thoroughly, reducing the discharge time and improving the cleaning efficiency.
[0030] Furthermore, the top ends of the multiple groups of support columns 7 are triangular in shape. The triangular structure has high mechanical stability, making the support columns 7 more stable.
[0031] Furthermore, the outer surface of the bottom end of multiple groups of support rods 2 is wrapped with rubber. The rubber wrapping layer can reduce the friction between the support rods 2 and the ground or other supporting surfaces, while providing a certain buffering effect to protect the equipment from the impact of uneven ground or vibration.
[0032] Working Principle: To clean accumulated material, the operator initiates the cleaning program on the industrial computer. First, the negative pressure blower at the top of the accumulated material collection bucket 6 activates. The blower's internal motor 412 drives the shaft 414, which in turn rotates the blades 415 at high speed, generating a powerful negative pressure suction force. This suction creates an effective airflow channel in the dead space between the scraper head 4 and the scraper tail 5. Leveraging the atmospheric pressure difference, the accumulated material in this dead space is drawn through the connecting pipe 8 into the accumulated material collection bucket 6.
[0033] A filter bag 711 is installed inside the accumulated material collection bucket 6, effectively preventing large particles and impurities from directly entering the negative pressure blower system, protecting the blower from damage. Furthermore, a level switch 611 is mounted on the upper inner wall of the accumulated material collection bucket 6 to monitor the material accumulation within the bucket in real time. When the material accumulation reaches a preset threshold, the level switch 611 sends a signal to the control system, automatically shutting down the negative pressure blower and stopping the material intake process.
[0034] Subsequently, the control system triggers the discharge mechanism. The electronic valve 512, mounted on the discharge pipe 511 at the bottom of the material collection barrel 6, automatically opens, allowing the collected material within the barrel to fall back into the conveyor scraper body 1 through the discharge pipe 511 under the action of gravity. The material is then carried to the warehouse or the next processing step by the movement of the subsequent conveyor chain. During the discharge process, if the material level switch 611 in the material collection barrel 6 detects that the material has been emptied, it will again send a signal to the control system, closing the electronic valve 512 and preparing to enter the next round of material cleaning cycle. Furthermore, to improve discharge efficiency, the material collection barrel 6 can also be equipped with a vibration motor, which promotes the rapid and thorough discharge of material through vibration, ensuring effective cleaning.
[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
