Description

Technical Field

[0001] The present invention relates to the technical field of belt conveyor equipment, and in particular to a novel belt cleaner. Background Art

[0002] In modern industrial production, belt conveyors, as an important material conveying equipment, are widely used in various fields. Belt conveyors are primarily composed of belts, drive units, rollers, and tensioning devices. The belt is the core component of the conveyor, responsible for carrying and transporting materials. However, belt conveyors often encounter various problems during operation, including belt breakage. When a belt is damaged, repair tape is often used to extend its life. However, after repairing with repair tape, the repaired area often protrudes above the overall belt surface.

[0003] During belt conveyor operation, the front cleaner plays a vital role. Its primary function is to remove debris, such as coal dust and dust, from the belt surface to ensure proper operation. However, due to the uneven surface of the repaired belt, the front cleaner can lift the repaired area when it encounters it. This can not only cause further damage to the repaired area but may even cause the belt to tear, seriously disrupting normal production.

[0004] Furthermore, adjusting the cleaner is a critical issue. If the cleaner is too tight, it can lift the belt, increasing the risk of tearing. If it is too loose, it can fail to clean properly, causing materials like pulverized coal to leak onto the return belt. This not only affects belt cleanliness but can also damage subsequent equipment, increasing maintenance costs. How to effectively resolve the conflict between the cleaner and the damaged belt after repair, and how to properly adjust the tightness of the cleaner to ensure the normal operation of the belt conveyor, have become pressing technical challenges.

[0035] like Figures 1 to 3 As shown, the present invention provides a new belt cleaner, comprising: a forward double-blade scraper, a counterweight device 5, a mounting bracket 3, and a detection device 6;

[0036] The forward double-blade scraper is connected to the counterweight device 5 through a connecting component, and the contact edge of the forward double-blade scraper and the belt is arc-shaped. The forward double-blade scraper and the counterweight device 5 are installed on the mounting bracket 3;

[0037] The forward double-blade scraper is used to automatically pass forward when encountering a repaired belt, and the counterweight device 5 is used to make the forward double-blade scraper automatically return to its original position after passing and continue to clean the hanging coal.

[0038] Furthermore, the forward-moving twin-blade scraper and counterweight device 5 are mounted on the mounting bracket 3. The mounting bracket 3 is equipped with multiple mounting holes arranged in an array to facilitate installation. A connecting member connects the forward-moving twin-blade scraper and the counterweight device 5, with the connection point located at the scraper's center of gravity to ensure its stability. The mounting bracket 3 also features an adjustment device 4, which adjusts the distance between the forward-moving twin-blade scraper and the belt. The adjustment device 4 is a screw structure, and by rotating the screw, the distance between the scraper and the belt can be precisely adjusted to achieve the optimal cleaning effect.

[0039] When the belt is operating normally and has not been repaired, the counterweight device 5 uses the connecting component to ensure that the forward double-blade scrapers are in close contact with the belt surface. The forward double-blade scrapers include a first scraper 1 and a second scraper 2, which are set at a certain angle (angle of 30°-60°) and have serrated edges. The length of the first scraper 1 is L1, and the length of the second scraper 2 is L2, where L1>L2, and the difference between L1 and L2 ranges from 5 to 15 cm. This design can better adapt to different cleaning needs and improve cleaning efficiency.

[0040] When the belt runs to the repair position, the detection device 6 detects the repair position and repair height of the belt. When the forward double-blade scraper encounters the repaired belt, it will automatically pass the repair position in the forward direction because its contact edge with the belt is curved, so as to avoid damage to the repaired area.

[0041] After passing the repair position, the gravity of the counterweight device 5 automatically returns the forward double-blade scraper to its original position through the connecting parts. After returning to its original position, the forward double-blade scraper continues to clean the hanging coal to ensure the cleanliness of the belt.

[0042] Furthermore, the forward double-blade scraper includes a first scraper 1 and a second scraper 2, the first scraper 1 and the second scraper 2 are arranged at a certain angle, and the cutting edges of the first scraper 1 and the second scraper 2 are both serrated, the lengths of the first scraper 1 and the second scraper 2 are different, the angle between the first scraper 1 and the second scraper 2 is 30°-60°, and the connection point between the connecting component and the forward double-blade scraper is located at the center of gravity of the scraper.

[0043] Furthermore, the serrated edge increases friction and can effectively remove stubborn coal; scrapers of different lengths and specific angle settings expand the cleaning range and improve cleaning accuracy; the connection point is located at the center of gravity to ensure smooth scraper movement and improve cleaning accuracy and stability.

[0044] Furthermore, the length of the first scraper 1 is L1, and the length of the second scraper 2 is L2, wherein L1>L2, and the difference between L1 and L2 is in the range of 5-15 cm.

[0045] Furthermore, the counterweight device 5 includes a counterweight block and a connecting component, and the counterweight block is a structure with adjustable weight.

[0046] Furthermore, the weight-adjustable counterweight can be flexibly adapted according to the belt operating conditions, ensuring that the scraper can return to its original position stably and clean effectively under different working conditions, thereby improving the versatility and adaptability of the cleaner.

[0047] Furthermore, the connecting component is a chain or a rope, and the connection point between the connecting component and the forward double-blade scraper is located at the center of gravity of the forward double-blade scraper.

[0048] Furthermore, the mounting bracket 3 is provided with a plurality of mounting holes, which are distributed in an array and are used for mounting the forward double-blade scraper and the counterweight device 5 .

[0049] Furthermore, an adjustment device 4 is provided on the mounting bracket 3 for adjusting the distance between the forward double-blade scraper and the belt. The adjustment device 4 is a screw structure. The screw structure and the specific pitch can accurately adjust the distance between the scraper and the belt to adapt to different belt conditions, avoid improper contact between the scraper and the belt, and extend the service life of the equipment.

[0050] Furthermore, a protective cover is provided on the outside of the forward double-blade scraper and the counterweight device 5. The metal protective cover prevents the entry of debris and protects the normal operation of the internal components; the appropriate thickness ensures the strength of the protective cover, provides safety protection, and prevents personnel from accidentally contacting the moving parts.

[0051] Furthermore, the detection device 6 is used to detect the repair position and repair height of the belt, and the detection device 6 is a laser sensor or an ultrasonic sensor.

[0052] Furthermore, the installation angle of the laser sensor or ultrasonic sensor is 30°-60° to the belt surface, and its installation height is 10-20 cm from the belt surface. The high-precision detection device 6 obtains the belt repair information in advance, so that the sweeper adjusts the working state in advance, reduces damage to the belt, optimizes the cleaning effect, and improves the intelligence level of the sweeper.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
