Description

Technical Field

[0001] The utility model relates to a combined sweeper and belongs to the technical field of sweeping equipment. Background Art

[0002] At present, when cleaning conveyor belts, only one type of cleaning equipment is generally used. Since the function of a single cleaner is relatively single, its applicability in certain specific scenarios may be limited. This makes it impossible to achieve the ideal cleaning effect when facing impurities of different types and states, and it cannot better cope with various complex situations. Therefore, a combined cleaner is proposed. Utility Model Content

[0003] The purpose of the utility model is to provide a combined sweeper to solve the problems raised in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a combined cleaner, comprising a rotary power cleaner fixedly arranged below the conveyor belt of the middle frame of the belt conveyor, a high-frequency vibration cleaner arranged above the conveyor belt, and a high-pressure air cleaner arranged below the conveyor belt;

[0005] The rotary power cleaner includes a drum, which is arranged perpendicularly to the moving direction of the conveyor belt. A plurality of scrapers are arranged in a circular array on the outer wall of the drum. The drum is arranged perpendicularly to the moving direction of the conveyor belt. The scrapers can fully cover the width of the conveyor belt. The side of the plurality of scrapers away from the drum is closely attached to the lower surface of the conveyor belt. The rotating motion of the drum drives the scrapers to scrape the surface of the conveyor belt to remove debris and residues.

[0006] The high-frequency vibration cleaner comprises a vibration plate, a plurality of buffer strips are evenly distributed on the lower surface of the vibration plate, the lower surfaces of the plurality of buffer strips are closely attached to the upper surface of the conveyor belt, and at least one vibration motor capable of generating high-frequency vibration is arranged on the upper surface of the vibration plate, and the high-frequency vibration generated by the vibration motor is transmitted to the conveyor belt through the vibration plate and the buffer strips;

[0007] The high-pressure air sweeper includes a high-pressure pipe, which is arranged perpendicular to the moving direction of the conveyor belt. One end of the high-pressure pipe is connected to an external high-pressure pump through a connecting pipe. The external high-pressure pump can transport high-pressure gas to the inside of the high-pressure pipe through the connecting pipe. A plurality of high-pressure fan-shaped nozzles are distributed in a linear array on the high-pressure pipe. The distribution of the high-pressure pipe ensures that the entire width of the conveyor belt can be evenly cleaned and covered, and the nozzle of each high-pressure fan-shaped nozzle faces the lower surface of the conveyor belt. The high-pressure fan-shaped nozzle is designed to generate a fan-shaped high-pressure airflow.

[0008] Preferably, a plurality of mounting plates are fixedly mounted in a circular array on the outer wall of the drum, and each scraper is fixed on a corresponding mounting plate. The arrangement of the mounting plates enables the installation of the scrapers, making it easy for the scrapers to be installed on the mounting plates.

[0009] Preferably, two hangers are symmetrically fixedly installed on the middle frame of the belt conveyor, and the two ends of the roller are rotatably sleeved on the side walls of the hanger on the same side, allowing the roller to rotate freely.

[0010] Preferably, a drive motor is provided on any hanger, and the output end of the drive motor is transmission-connected to one end of the roller. When the drive motor is running, the output end of the drive motor can drive the roller to rotate, causing the roller to rotate on the hanger with the scraper, and the scraper will scrape the lower surface of the conveyor belt to remove debris and residues.

[0011] Preferably, each buffer strip is provided with a plurality of T-bolts, the threaded ends of the plurality of T-bolts are meshedly connected to the side wall of the vibration plate, a threaded hole matching the threaded end of the T-bolt is provided on the vibration plate, the T-end of the T-bolt is fixed to the buffer strip, and by meshingly connecting the threaded end of the T-bolt in the threaded hole, the buffer strip can be stably fixed to the vibration plate.

[0012] Preferably, the scraper and the buffer strip can be made of rubber material. The design of the scraper and the buffer strip can reduce the impact and wear of the cleaner on the conveyor belt.

[0013] Preferably, the spraying angle of the high-pressure fan-shaped nozzle forms an acute angle with the lower surface of the conveyor belt.

[0014] Preferably, the spray angle of the high-pressure fan-shaped nozzle and the lower surface of the conveyor belt are at an angle of 90°.

[0015] Compared with existing technologies:

[0016] The utility model uses a high-frequency vibration cleaner alone and is used in scenes with high cleaning efficiency requirements, and can quickly and effectively remove relatively dry and less sticky materials;

[0017] The combination of high-frequency vibration cleaner and high-pressure air cleaner can give full play to the advantages of the two cleaners. When the material is relatively dry and sticky, the high-frequency vibration cleaner can be used to shake off most of the material, and the high-pressure air cleaner can be used to remove the remaining tiny impurities to achieve a thorough cleaning effect.

[0018] Through the combination of high-frequency vibration cleaner and rotary power cleaner, in this case, when the material has high moisture content and high viscosity, the rotary power cleaner can more effectively remove slippery and sticky materials, ensuring the normal operation of the conveyor belt and extending its service life.

[0027] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.

[0028] Example 1

[0029] like Figure 1-Figure 2 As shown, in this embodiment, a combined cleaner is provided, comprising a rotary power cleaner 3 fixedly mounted below the conveyor belt 2 of the belt conveyor intermediate frame 1, a high-frequency vibration cleaner 4 arranged above the conveyor belt 2, and a high-pressure air cleaner 5 arranged below the conveyor belt 2;

[0030] The rotary power cleaner 3 includes a roller 301, which is arranged perpendicular to the moving direction of the conveyor belt 2. A plurality of scrapers 302 are arranged in a circular array on the outer wall of the roller 301. The side of the plurality of scrapers 302 away from the roller 301 is closely attached to the lower surface of the conveyor belt 2.

[0031] The rotary power cleaner 3 can effectively remove the debris and residues on the conveyor belt 2. The rotary motion of the roller 301 drives the scraper 302 to scrape the surface of the conveyor belt 2 to remove the debris and residues. Moreover, since the roller 301 is arranged perpendicular to the moving direction of the conveyor belt 2, the scraper 302 can fully cover the width of the conveyor belt 2 to ensure that the debris and residues are completely removed.

[0032] The high-frequency vibration cleaner 4 includes a vibration plate 401, a plurality of buffer strips 402 are evenly distributed on the lower surface of the vibration plate 401, the lower surfaces of the plurality of buffer strips 402 are closely attached to the upper surface of the conveyor belt 2, and at least one vibration motor 403 capable of generating high-frequency vibration is arranged on the upper surface of the vibration plate 401;

[0033] The high-frequency vibration generated by the vibration motor 403 is transmitted to the conveyor belt 2 through the vibration plate 401 and the buffer strip 402. This high-frequency vibration can effectively remove the debris and residues on the conveyor belt 2. On the one hand, the vibration can loosen the debris on the surface of the conveyor belt, making it easier to remove. The vibration motor 403 can be of model YZS-15-4;

[0034] The high-pressure air cleaner 5 includes a high-pressure pipe 501, which is arranged perpendicular to the moving direction of the conveyor belt 2. One end of the high-pressure pipe 501 is connected to an external high-pressure pump through a connecting pipeline. The external high-pressure pump can deliver high-pressure gas to the inside of the high-pressure pipe 501 through the connecting pipeline. A plurality of high-pressure fan-shaped nozzles 502 are distributed in a linear array on the high-pressure pipe 501. The distribution of the high-pressure pipe 501 ensures that the entire width of the conveyor belt 2 can be evenly cleaned and covered, and the nozzle of each high-pressure fan-shaped nozzle 502 faces the lower surface of the conveyor belt 2. The high-pressure fan-shaped nozzle 502 is designed to generate a fan-shaped high-pressure airflow.

[0035] The fan-shaped airflow shape can better adapt to the width of the conveyor belt 2 and provide a wider cleaning range. The impact force of the high-pressure airflow directly acts on the lower surface of the conveyor belt 2. By directly aiming at the lower surface of the conveyor belt, the high-pressure airflow can more effectively blow away impurities from the conveyor belt 2, thereby achieving the purpose of cleaning;

[0036] Use scenarios:

[0037] Scenario 1: When the material is relatively dry and not very sticky, the high-frequency vibration cleaner 4 can be used alone;

[0038] Scenario 2: The material is relatively dry and sticky, and a combination of a high-frequency vibration cleaner 4 and a high-pressure air cleaner 5 is used;

[0039] Scenario 3: The material has high moisture content and high viscosity, and a high-frequency vibration cleaner 4 and a rotary power cleaner 3 are used in combination.

[0040] Example 2

[0041] like Figure 1-Figure 4 As shown, on the basis of Example 1, in order to scrape and clean the lower surface of the conveyor belt 2, a plurality of mounting plates 303 are fixedly installed on the outer wall of the roller 301 in a circular array, and each scraper 302 is respectively fixed on the corresponding mounting plate 303. The setting of the mounting plate 303 can install the scraper 302, which facilitates the installation of the scraper 302 on the mounting plate 303.

[0042] like Figure 1 , Figure 3 As shown, in order to fix the rotary power cleaner 3 on the middle frame 1 of the belt conveyor, two hangers 7 are symmetrically fixedly installed on the middle frame 1 of the belt conveyor, and the two ends of the roller 301 are rotatably sleeved on the side walls of the hangers 7 on the same side, allowing the roller 301 to rotate freely.

[0043] like Figure 1 , Figure 3 As shown, in order to drive the roller 301 and the scraper 302 to rotate, a driving motor 8 is arranged on any hanger 7, and the output end of the driving motor 8 is transmission-connected with one end of the roller 301. When the driving motor 8 is running, the output end of the driving motor 8 can drive the roller 301 to rotate, so that the roller 301 rotates with the scraper 302 on the hanger 7, and the scraper will scrape the lower surface of the conveyor belt 2 to remove debris and residues.

[0044] Example 3

[0045] like Figure 5-Figure 6 As shown, on the basis of Example 1, in order to be able to fix the buffer bar 402 on the vibration plate 401, each buffer bar 402 is provided with a plurality of T-bolts 6, and the threaded ends of the plurality of T-bolts 6 are meshed and connected to the side wall of the vibration plate 401, and the vibration plate 401 is provided with threaded holes that are compatible with the threaded ends of the T-bolts 6, and the T-ends of the T-bolts 6 are fixed on the buffer bar 402. By meshing the threaded ends of the T-bolts 6 in the threaded holes, it can be ensured that the buffer bar 402 is stably fixed on the vibration plate 401.

[0046] In order to protect the surface of the conveyor belt 2 and prevent the surface of the conveyor belt 2 from being damaged, the scraper 302 and the buffer strip 402 can be made of rubber material. The design of the scraper 302 and the buffer strip 402 can reduce the impact and wear of the sweeper on the conveyor belt 2 and protect the surface of the conveyor belt 2 from being damaged.

[0047] Example 4

[0048] like Figure 1 , Figure 2 as well as Figure 7As shown, based on Example 1, in order to better blow and clean the lower surface of the conveyor belt 2, the spray angle of the high-pressure fan-shaped nozzle 502 is at an acute angle to the lower surface of the conveyor belt 2.

[0049] Example 5

[0050] like Figure 1 As shown, based on Example 1, in order to better purge and clean the lower surface of the conveyor belt 2, the spray angle of the high-pressure fan-shaped nozzle 502 and the lower surface of the conveyor belt 2 are set at an angle of 90°.
