Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor conveying systems, in particular to an automatic dust cleaning device for a belt conveyor. Background Art

[0002] Belt conveyor, whose full name is belt conveyor, is a mechanical device that relies on the friction between the driving roller and the belt to drive the belt to transport goods. It has a simple structure, low power consumption, and large conveying capacity. It is widely used in the transportation of grain, coal and other goods at docks. Common belt conveyors mainly include roller-type belt conveyors that support the conveyor belt with rollers and air cushion belt conveyors that support the conveyor belt with air films.

[0003] During the grain transportation process at the terminal, the operation can only be completed through the transportation of multiple belt conveyors. The grain crops transported by the previous belt conveyor are poured into the next belt conveyor through the unloading port. Therefore, a large amount of grain dust will be generated at the head and tail of the belt conveyor. In order to avoid affecting the normal operation of the belt conveyor, it is necessary to regularly clean the grain dust at the head and tail.

[0004] In the past, dust cleaning was mainly done manually. When the equipment was stopped, the staff opened the window and cleaned it manually. This was not only a large workload, but also posed certain safety hazards. While wasting manpower, the shutdown cleaning also affected the operating efficiency of the belt conveyor equipment, resulting in an increase in time costs. Utility Model Content

[0037] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the utility model will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] Reference Figure 1-10 This embodiment provides an automatic dust cleaning device for a belt conveyor, including a head chassis 1, an endless belt and a tail chassis 7.

[0039] The head of the endless belt is located in the head case 1, and the bottom of the head case 1 is connected to the lower hopper 2. An inclined support frame 3 is installed outside the head case 1, and the inclined support frame 3 gradually tilts toward the ground from the head direction to the tail direction of the endless belt. A head annular scraper mechanism is provided in the head case 1, and the head annular scraper mechanism is located below the endless belt. The running direction of the head annular scraper mechanism is consistent with the running direction of the belt conveyor. The head annular scraper mechanism includes a head drive motor 4, which is connected to the first sprocket 5 in transmission, and the first sprocket 5 is connected to the second sprocket 6 in transmission through the first transmission chain. A plurality of scrapers are installed on the first transmission chain, and the first sprocket 5 and the second sprocket 6 are both located below the endless belt.

[0040] The tail of the endless belt is located in the tail case 7, and a tail annular scraper mechanism is arranged in the tail case 7. The running direction of the tail annular scraper mechanism is perpendicular to the running direction of the belt conveyor, and the tail annular scraper mechanism is arranged around the endless belt. The tail annular scraper mechanism includes a tail drive motor 8, which is connected to the third sprocket 9 by transmission, and the third sprocket 9 is connected to the fourth sprocket 10 by transmission through the second transmission chain. A plurality of scrapers are installed on the second transmission chain, and the third sprocket 9 and the fourth sprocket 10 are respectively located above and below the endless belt. A blank cleaning mechanism 11 is also arranged in the tail case 7, and the blank cleaning mechanism 11 is located in the annular space in the middle of the endless belt. The blank cleaning device is a V-shaped blank cleaning device. A spraying mechanism is arranged on the top of the tail case 7, and the spraying mechanism includes a water pipe and a nozzle, and the nozzle faces the working surface of the endless belt.

[0041] The working principle of this specific embodiment is:

[0042] When the material is transported to the head chassis 1 by the circular belt and poured into the lower hopper 2, the material will impact the air in the lower hopper 2, causing the air pressure at the bottom of the lower hopper 2 to change, generating an upward recoil airflow, and generating a large amount of material dust in the head chassis 1, part of which will fall back into the lower hopper 2 due to gravity, and the other part of the material dust will fall to the bottom of the box under the circular belt. At this time, the head circular scraper mechanism rotates along the return direction of the belt conveyor under the drive of the head drive motor 4, pushing the material dust that falls on the bottom of the box into the lower hopper 2, avoiding the adverse effects of material dust accumulation on the operation of the belt conveyor and realizing real-time cleaning of the dust in the head chassis 1 of the belt conveyor.

[0043] In the tail chassis 7, when the material dust is scattered to the bottom of the tail chassis 7 due to the impact of the airflow, the tail drive motor 8 drives the tail annular scraper mechanism to operate perpendicular to the running track of the annular belt, scraping up the material dust at the bottom of the tail chassis 7 and dumping it onto the upper working surface of the annular belt, so that the material dust re-enters the transportation process. In addition, the V-shaped empty section cleaner can perform return cleaning on the non-working surface of the annular belt. The tip of the V-shaped empty section cleaner is set away from the tail of the annular belt. During the cleaning process, the material will move along the V-shaped empty section cleaner to the tail of the annular belt, and then leave the non-working surface of the annular belt to reach the bottom of the tail chassis 7, and finally be scraped up by the tail annular scraper mechanism and dumped onto the upper working surface of the annular belt, so that the material dust re-enters the transportation process, avoiding the accumulation of material dust in the annular space surrounded by the annular belt, and ensuring the all-round cleaning of the material dust at the tail of the belt conveyor.

[0044] This embodiment can automatically clean the material dust at the head and tail of the belt conveyor, realize the continuous operation of the belt conveyor, reduce labor input, reduce labor intensity, improve operation efficiency, and at the same time reduce the economic losses caused by material scattering and improve economic benefits.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
