Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of industrial production and material processing, and specifically relates to a scraper machine scraping rod automatic cleaning device. BACKGROUND

[0002] In the field of industrial production and material processing, the scraper machine as a key continuous conveying equipment is widely used in coal, ore, chemical industry, grain and other industries, and undertakes the task of transporting bulk materials from one place to another. The scraper machine is usually equipped with standard specification scraping rods, such as standard scraping rods of 65, 95 and other models. While these scraping rods push the material forward, the groove structure designed on the back of the scraping rod becomes a "breeding ground" for returned materials. During the operation of the scraping rod, these grooves are easy to capture and carry small particles of coke powder into the return area of the scraper machine. This phenomenon is called scraper machine return, which not only reduces the overall conveying efficiency of the conveyor, increases energy consumption, but also may cause material accumulation in the return box.

[0003] When the return of the scraper machine and the conveying path are separated in different spaces, the return problem becomes more serious. The material accumulated in the return box will continue to increase, and long-term operation will easily block the return box of the scraper machine, affecting the normal operation of the equipment. The blocked return box not only causes the equipment to stop, but also increases the maintenance cost and reduces the production efficiency. In addition, the return problem will also cause serious wear and tear to the return box and the scraping rod of the scraper machine. Small particles of material continuously rub and impact the box wall and the scraping rod in the return box, causing the surface of the box wall and the scraping rod to wear out, shortening the service life of the equipment. This wear not only reduces the performance of the equipment, but also may cause equipment failure and increase safety risks.

[0004] The existing technology mainly increases the coating on the surface of the scraping rod or changes the material of the scraping rod to improve its wear resistance; however, this scheme has certain limitations and cannot fundamentally solve the scraper machine return problem.

[0030] Example 1

[0031] like Figure 1 As shown, this embodiment provides an automatic cleaning device for the scraper bar of a scraper conveyor. The automatic cleaning device is set on the upper part of the scraper bar at the tail of the scraper conveyor. The automatic cleaning device includes a cleaning pendulum 1, a fixed shaft 2, a fixed bracket 3, a connecting slider 4, and a shaft seat 5. The swing arms of the cleaning pendulum 1 are respectively mounted on the fixed shaft 2 through the connecting slider 4. Several fixed brackets 3 are set on the hopper of the scraper conveyor along the conveying direction of the scraper conveyor. The fixed brackets 3 are located above the scraper bar at the tail of the scraper conveyor. The fixed shaft 2 is mounted on the fixed bracket 3. Several connecting sliders 4 are set on the fixed shaft 2 and are respectively connected to a single cleaning pendulum 1. The pendulum body of the cleaning pendulum 1 hangs down naturally and contacts the scraper bar of the scraper conveyor.

[0032] The pendulum body of the cleaning pendulum 1 is made of wear-resistant, corrosion-resistant high-strength alloy material, ensuring the stability and durability of the cleaning pendulum 1 under long-term use

[0033] The fixing support 3 is provided with four fixing supports, and there are three groups of adjacent fixing supports 3. The interval between the outermost two groups of adjacent fixing supports 3 is equal, and the interval between the outermost two groups of adjacent fixing supports 3 is smaller than the interval between the middle group of adjacent fixing supports 3. A plurality of cleaning pendulums 1 are arranged on the fixing shaft 2 between the adjacent fixing supports 3.

[0034] As shown in Figure 2 The fixing shaft 2 and the fixing support 3 are connected to the shaft seat 5, the fixing shaft 2 is fixed to the fixing support 3 through the shaft seat 5, the shaft seat 5 is provided with a clamping groove matched with the fixing shaft 2, and the fixing shaft 2 is installed on the shaft seat 5 through the clamping groove.

[0035] The cleaning pendulum 1 naturally droops under the action of gravity. When the scraper moves forward, the forward movement of the scraper drives the cleaning pendulum 1 to make a circular motion to lift the cleaning pendulum 1. When the cleaning pendulum 1 is lifted to a certain height, the cleaning pendulum 1 is out of contact with the scraper, and the cleaning pendulum 1 makes a reverse circular motion under the action of gravity. At this time, the next scraper moves forward and collides with the cleaning pendulum 1, and the cleaning pendulum 1 forms a beating action on the scraper, which shakes off the material adhering to the surface of the scraper and the chute. The material falls into the bin under the action of gravity, achieving the purpose of cleaning. The cleaning pendulum 1 is connected to the fixing shaft 2 through the connecting sliding block 4, and is installed in the connecting sliding block 4 hole without resistance through the self-locking device. The fixing shaft 2 is fixed to the bin through the fixing support 3, reducing the movement resistance.

[0036] The scraper automatic cleaning device provided by the embodiment reduces the return material of the scraper conveyor, prolongs the cycle of the internal space of the cleaning equipment, and effectively ensures the long-term stable operation of the equipment.

[0037] Embodiment two

[0038] The embodiment provides a scraper automatic cleaning device, which comprises a cleaning pendulum 1, a fixing shaft 2, a fixing support 3 and a connecting sliding block 4. The swing arms of the plurality of cleaning pendulums 1 are respectively installed on the fixing shaft 2 through the connecting sliding block 4. The fixing support 3 is arranged on the bin of the scraper conveyor along the conveying direction of the scraper conveyor. The fixing support 3 is located above the scraper at the tail of the scraper conveyor. The fixing shaft 2 is installed on the fixing support 3. The connecting sliding block 4 is arranged on the fixing shaft 2 and connected to a single cleaning pendulum 1. The pendulum body of the cleaning pendulum 1 naturally droops and contacts the scraper of the scraper conveyor. The connecting sliding block 4 is provided with a self-locking device, and the cleaning pendulum 1 is installed on the connecting sliding block 4 through the self-locking device.

[0039] The length of the swing arm of the cleaning pendulum 1 is less than or equal to the distance between the tail scraper and the bin, and the length of the swing arm of a single cleaning pendulum 1 is less than the distance between the cleaning pendulums 1 adjacent to it, preventing the front and rear cleaning pendulums 1 from colliding with each other.

[0040] The distance between the adjacent cleaning pendulums 1 in the natural drooping state is equal to the distance between the adjacent scrapers of the tail of the scraper conveyor, ensuring that each scraper can be cleaned.

[0041] In the embodiment, the cleaning pendulum 1 first contacts the scraper, and the cleaning pendulum 1 performs a circular motion around the fixed shaft 2 during the forward movement of the scraper, and the cleaning pendulum 1 is connected to the fixed shaft 2 through the connecting sliding block 4, the connecting sliding block 4 is provided with a self-locking device, and the cleaning pendulum 1 is fixed on the fixed shaft 2 above the scraper without resistance, so that the resistance of the cleaning pendulum 1 during the circular motion is minimized, and the effect of free rotation is achieved. When the scraper passes around the tail wheel and enters the return box, the distance between the cleaning pendulum 1 and the scraper becomes longer, and the upward thrust of the cleaning pendulum 1 is instantaneously removed, and the cleaning pendulum 1 performs a reverse circular motion by gravity and contacts the next forward scraper, and is instantaneously pushed forward, and the acceleration of the cleaning pendulum 1 is very large at the moment of contact, and a large force is generated on the scraper, and the scraper will vibrate and shake, and the material adhered to the surface of the scraper and the chute will be shaken off and fall into the bin, achieving the effect of cleaning the scraper.

[0042] The difference between the embodiment and the first embodiment is that the length of the swing arm of the cleaning pendulum and the distance between the adjacent cleaning pendulums are limited, which ensures that the automatic cleaning device can stably clean the material adhered to each scraper during the operation of the scraper conveyor, and improves the effect of automatic cleaning.

[0043] As can be known from the technical common sense, the utility model can be realized through other embodiments without departing from the spirit or essential characteristics. Therefore, the above-mentioned disclosed embodiments are only examples, and are not the only ones, and all changes within the scope of the utility model or within the scope equivalent to the utility model are included in the utility model.
