[0002] As a crucial piece of equipment in sand and gravel aggregate processing systems, belt conveyors serve as a vital link between workshops, and their conveying capacity determines the overall system's production capacity. One of the key factors affecting the conveying capacity of belt conveyors is the nature of the material, including particle size, moisture content, abrasiveness, and adhesiveness. Among these, adhesiveness has the greatest impact. Highly adhesive materials will cause adhesion during conveying, with fine powder particles adhering to the belt surface, affecting transmission efficiency. Therefore, timely cleaning of the belt surface is necessary to ensure the conveying capacity of the belt.
[0003] The most common belt cleaning device is the belt cleaner, installed at the head of the belt conveyor to remove materials adhering to the belt and ensure the normal operation of the belt conveyor. However, some materials are highly adhesive, making cleaning difficult and prone to spillage along the way; at the same time, the cleaner blades wear out quickly, resulting in poor cleaning effect; and in some areas, installing cleaners can easily cause belt joint cracking, leading to overall belt tearing and posing a significant safety hazard to the conveyor operation.

[0024] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0025] Example 1:
[0026] See Figure 1-4 An active cleaning device for a non-powered belt conveyor includes a lifting roller 1, a brush roller 2, a support frame 3, a conveyor frame 4, a screw 5, a conveyor belt 6, a gear cover 7, and a conveyor drive unit 8. The lifting roller and brush roller are fixed parallel to each other on the support frame via bearing seats at both ends of their respective roller shafts. The lifting roller and brush roller are connected by a large gear 105 and a small gear 204. One side of the support frame 3 is fixedly connected to the conveyor frame 4 via bearing seat A103, and the other side is connected to the conveyor frame 4 via the screw 5. By activating the conveyor drive unit 8, the conveyor belt 6 drives the lifting roller to rotate, eliminating the need for additional power equipment. The large gear 105 on the lifting roller then drives the small gear 204 of the brush roller to rotate, thus cleaning impurities and dust from the surface of the conveyor belt. Adjusting the height of the screw 5 ensures close contact between the brush roller 2 and the surface of the conveyor belt 6. Gear covers 7 are installed on the outside of the large gear 105 and the small gear 204 to protect their rotating parts and ensure safe operation. This device is used for belt cleaning. It is driven by the normal operation of the belt conveyor, requiring no additional power equipment. Adjusting the screw height ensures a tight fit between the brush roller and the belt surface. Starting the belt conveyor drive rotates the lifting roller, which in turn drives the brush roller's small gear. The rapid rotation of the brush roller scrapes away dust and impurities adhering to the belt surface, effectively preventing dust accumulation, ensuring aggregate quality and belt conveyor efficiency, and preventing damage to the belt surface.
[0027] Furthermore, the lifting roller 1 includes a lifting roller shaft 101, a cylinder 102, bearing seats A103 and B104, and a large gear 105. The cylinder, bearing seats A and B, and the large gear are connected by the lifting roller shaft. Bearing seats A and B are arranged symmetrically around the center of the cylinder, and the large gear is located at one end of the lifting roller shaft. The lifting roller 1 can be used to transmit the power of the conveyor belt 6 to the brush roller 2. During operation, the conveyor belt 6 synchronously drives the lifting roller 1, which in turn drives the large gear 105. The large gear 105 drives the small gear 204, which in turn drives the brush roller 2.
[0028] Furthermore, the brush roller 2 includes a brush roller shaft 201, a brush cylinder 202, a bearing seat C203, and a pinion 204. The brush cylinder, bearing seat C, and pinion are connected circumferentially to the brush roller. The bearing seat C is arranged symmetrically around the center of the brush cylinder, and the pinion is located at one end of the brush roller shaft. The brush roller 2 described above can be used to clean the outer surface of the tape 6. During operation, the pinion 204 drives the brush roller shaft 201, which in turn drives the brush cylinder 202, which then cleans the outer surface of the tape 6.
[0029] Furthermore, the lifting roller 1 is fixed to the conveyor frame 4 via bearing seat A103, ensuring that the surface of the cylinder 102 is in close contact with the conveyor belt 6, and is fixed to the support frame 3 via bearing seat B104; the brush roller 2 is fixed to the support frame 3 via bearing seat C203. Through the above-mentioned cooperation method, effective meshing transmission between the lifting roller 1 and the conveyor belt is ensured.
[0030] Furthermore, the support frame 3 is connected to the conveyor belt frame 4 on the side near the brush roller 2 via a screw 5. Adjusting the screw height ensures that the brush roller 2 and the conveyor belt 6 maintain a close fit. The screw 5 described above can be used to achieve height adjustment.
[0031] Furthermore, the large gear 105 and the small gear 204 are equipped with protective covers 7 to protect their rotating parts and ensure safe operation.
[0032] Furthermore, the device starts the belt conveyor drive device 8, which drives the lifting roller cylinder to rotate via the belt, and then the large gear on the lifting roller drives the small gear on the brush roller to rotate, thereby cleaning the impurities and dust on the surface of the belt through the rotation of the brush cylinder.
[0033] The working process and principle of the active cleaning device for a non-powered belt conveyor described in this utility model:
[0034] Step 1: First, assemble and connect the device components in sequence, adjust the screw height to ensure that the brush roller is in close contact with the tape surface, and at the same time check the integrity and stability of the device.
[0035] Step 2: Turn on the conveyor belt drive device. The conveyor belt drive will rotate the lifting roller. At the same time, the large gear at the end of the lifting roller will drive the small gear of the brush roller to rotate, thus completing the entire process of starting the brush roller.
[0036] Step 3: Check the cleanliness of the tape surface and adjust the screw height as needed to achieve the best cleaning effect.
