Description

Technical Field

[0001] The utility model relates to the technical field of belt conveying, in particular to a belt scraping device. Background Art

[0002] Belt conveyors are widely used in mining, metallurgy, building materials, food and other industries. They are energy-efficient, highly automated and highly adaptable, and can greatly reduce manual labor. For steel companies, materials often stick together during the feeding process of belt conveyors, which requires timely cleaning of the sticky materials. If not cleaned in time, it may affect the safe operation of the belt conveyor, and accelerate the wear of the belt and other components, affecting the service life, and also have a certain impact on the environmental protection of the work site. The existing scraper plate is generally set at the roller at the drop end. The scraper plate is in a straight plate shape and is close to the belt for scraping. The problems are: first, when the sticky material is serious, the entire scraper squeezes the sticky material on the belt at the same time, which is easy to damage the belt; second, if the bonding force is too large, it will also damage the scraper plate or scratch the belt; third, the machine needs to be shut down for maintenance or overhaul, which affects production.

[0003] The scraper disclosed in the Chinese patent application number CN201520323332.3 and titled "A belt scraper" includes a scraper skin positioning sleeve, a scraper skin positioning sleeve bracket, and a scraper skin. The scraper skin positioning sleeve is fixed to the scraper skin positioning sleeve bracket and is arranged at the right end of the head of the belt conveyor. The scraper skin passes through the scraper skin positioning sleeve and contacts the belt located at the right end of the active roller. The patented belt scraper can realize automatic feeding of the scraper skin without manual monitoring and adjustment, saving human resources, but it does not involve the above-mentioned problems.

[0011] The beneficial effects of the utility model are as follows: First, by setting the first scraper assembly in the return section of the belt, the first scraper plate is V-shaped, and the V-shaped tip bottom is in line with the running direction of the belt. During the running of the belt, the adhesive material is first brought into contact with the V-shaped tip bottom, and the contact area is small, and then the contact area is gradually increased, which is convenient for scraping off the adhesive material. Second, the first scraper plate can rotate around the rotating shaft, and under the action of the top pressure spring, it can flexibly press against the contact belt. When the adhesion is particularly serious, the first scraper plate can compress the spring to avoid damaging the belt or the first scraper assembly.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1-3 As shown, the belt scraper device provided by the utility model includes a first scraper component 1, a scraper roller 2, and a vibration component 3; the first scraper component 1 is arranged on the return section of the belt 6, and is located below the belt conveyor. The first scraper plate 1-1 in the first scraper component 1 is V-shaped, and the pointed bottom of the V-shape faces the running direction of the belt 6; a scraper roller 2 matching the first scraper component 1 is arranged above the return section of the belt 6, and the scraper roller 2 has a V-shaped structure; according to the running direction of the belt 6, the vibration component 2 is arranged upstream of the first scraper component 1; a receiving hopper 4 is arranged below the first scraper component 1 and the vibration component 3.

[0020] The V-shaped tip of the first scraper 1-1 meets the running direction of the belt 6, that is, the V-shaped tip rushes towards the adhesive on the belt 6. During the running of the belt 6, the adhesive is first brought into contact with the V-shaped tip, and the contact area is small, and then the contact area is gradually increased, which is convenient for scraping off the adhesive. The first scraper 1-1 can be set perpendicular to the belt 6, or it can be set at an acute angle to the belt 6 to facilitate scraping off the adhesive. The scraper device is set in the return section of the belt. Another advantage is that it is easy to maintain and can be inspected and repaired continuously.

[0021] During the scraping process, for materials with particularly severe material adhesion, the following structure can be used to protect the belt: the first scraper assembly 1 is composed of a first scraper plate 1-1, a pressure spring 1-2, and a base 1-3; a rotating shaft is provided at the end of the first scraper plate 1-1, and the rotating shaft is installed on the base 1-3. A pressure spring 1-2 is provided between the first scraper plate 1-1 and the base 1-3. Under the action of the pressure spring 1-2, the first scraper plate and the belt 6 can be pressed and contacted movably. The first scraper plate 1-1 can rotate around the rotating shaft, and under the action of the pressure spring 1-2, it can be pressed and contacted movably with the belt 6. When the adhesion is particularly severe, the first scraper plate 1-1 can compress the spring 1-2 to avoid damaging the belt 6 or the first scraper assembly 1.

[0022] In order to further protect the belt and the scraper assembly, the following scheme can be adopted: a second scraper assembly is added between the first scraper assembly 1 and the vibration assembly 3. The structure of the second scraper assembly is the same as that of the first scraper assembly 1. The second scraper plate 5-1 of the second scraper assembly is V-shaped. The second scraper plate 5-1 is arranged parallel to the first scraper plate 1-1, and the size of the second scraper plate 5-1 is smaller than the first scraper plate 1-1. During the operation of the belt 6, the second scraper assembly first partially removes the adhesive at the center of the belt, and the first scraper assembly then takes over to remove the remaining adhesive on both sides of the belt. The V-shaped angle α of the first scraper plate 1-1 is 80-110 degrees, and the V-shaped tip is set to an arc shape. The V-shaped tip is set to an arc shape, and when the belt 6 contacts the first scraper plate 1-1, the V-shaped tip can be prevented from damaging the belt 6. The second scraper plate 5-1 has the same arc structure at the V-shaped tip.

[0023] The vibration assembly 3 is provided to facilitate vibrating and loosening the adhesive material bonded to the belt 6. The vibration assembly 3 is composed of a vibration frame 3-1, a vibration roller 3-2 and a vibration motor 3-3 provided thereon. A vibration spring is provided between the vibration frame 3-1 and the ground, and the vibration roller 3-2 is in rolling contact with the belt 6. The vibration roller 3-2 is provided in rolling contact with the belt 6, which can effectively protect the belt 6 during the vibration process.
