Technical Field

[0001] This application relates to the technical field of unloaders, and specifically to an efficient belt conveyor unloader. Background Technique

[0002] A belt conveyor, also known as a belt conveyor, is a commonly used continuous conveying equipment. It usually consists of a driving device to tension the conveyor belt, making it move infinitely between the driving roller and the redirecting roller to convey materials. The belt conveyor unloader is a device installed on the belt conveyor. Its main function is to unload materials from the conveyor belt as needed during the operation of the belt conveyor. This device can significantly improve the flexibility and efficiency of material handling and is widely used in many industries such as building materials, metallurgy, chemical industry, and electric power. The existing belt conveyor unloaders are under the impact of raw materials such as coal, cement, and sand and gravel on the conveyor belt for a long time, and raw materials will inevitably adhere to their surfaces. It is rather troublesome to clean them manually only. Moreover, the uneven surface of the unloading plate increases the friction, which will also cause the flow path of the raw materials to be blocked, affecting the normal unloading efficiency. Content of the Utility Model

[0003] The purpose of this application is to provide an efficient belt conveyor unloader, which solves the problems in the background technique that the existing belt conveyor unloaders are under the impact of raw materials such as coal, cement, and sand and gravel on the conveyor belt for a long time, and raw materials will inevitably adhere to their surfaces. It is rather troublesome to clean them manually only. Moreover, the uneven surface of the unloading plate increases the friction, which will also cause the flow path of the raw materials to be blocked, affecting the normal unloading efficiency.

[0004] To achieve the above purpose, this application provides the following technical solution: An efficient belt conveyor unloader includes an unloader main body, a plow plate main body, a moving groove, and a scraper. A groove is opened on the front surface of the plow plate main body. A number of rotating rollers are evenly rotatably connected between the upper and lower surfaces of the groove, and a conveyor belt is drivingly connected to the surface of the rotating rollers. A support groove is fixedly connected to the surface of the plow plate main body on the opposite side of the groove. A number of shock absorbers are evenly fixedly connected to the outer side wall of the support groove, and the other end of the shock absorber is fixedly connected to a buffer plate. A moving groove is horizontally slidably connected to the inside of the support groove, and the inner side wall of the moving groove is in contact with the surface of the buffer plate. A threaded rod is rotatably connected to the inside of the moving groove, and a support rod is threadedly connected to the surface of the threaded rod. A rotating disc is rotatably connected to the inner bottom surface of the rotating groove opened on the upper side wall of the support rod, and a scraper is fixedly connected to the outer surface of the rotating disc. The side of the scraper facing the conveyor belt is in contact with the surface of the conveyor belt.

[0005] In this technical solution, after the raw materials hit the conveyor belt, the conveyor belt will rotate driven by the rotating rollers, carrying the raw materials to slide out of the conveyor belt better, so as to reduce the friction of the raw materials on the plow body, and can continuously change the rotation speed according to the impact force of the raw materials, improving the unloading efficiency. At the same time, through the moving groove, threaded rod, support rod, turntable and scraper, the surfaces of the plow body and the conveyor belt can be cleaned. When the first motor is started to drive the threaded rod to rotate, the support rod drives the scraper to move together. During the movement of the scraper, it will scrape the surfaces of the plow body and the conveyor belt, scraping off the attached raw materials. And when the support rod moves to both ends of the moving groove, after the second motor is started, it will drive the turntable to rotate, making the turntable drive the scraper to rotate to the rear side of the plow body, so as to avoid the scraper causing obstruction during the unloading process and improving the unloading efficiency.

[0006] As an alternative to the technical solution of the present application, a leakage hole is penetrated and opened at the bottom of the groove between the rotating rollers.

[0007] As an alternative to the technical solution of the present application, one end of the threaded rod is fixedly connected to the outer side wall of the moving groove facing it, and the outer end of the transmission shaft of the first motor is fixedly connected to the corresponding end of the threaded rod.

[0008] As an alternative to the technical solution of the present application, the top end of the support rod is fixedly connected to a second motor, and the outer end of the transmission shaft of the second motor is fixedly connected to the center of the top of the turntable below.

[0009] As an alternative to the technical solution of the present application, the moving groove and the buffer plate are threadedly connected by fixing bolts, and the fixing bolts are located on the outer surfaces of the left and right ends of the moving groove.

[0010] As an alternative to the technical solution of the present application, the bottom of the scraper is at the same horizontal plane as the bottom of the plow body.

[0011] Compared with the prior art, the beneficial effects of the present application are as follows:

[0012] 1. The present application can assist in unloading through the groove, rotating rollers and conveyor belt. After the raw materials hit the conveyor belt, the conveyor belt will rotate driven by the rotating rollers, carrying the raw materials to slide out of the conveyor belt better, so as to reduce the friction of the raw materials on the plow body, and can continuously change the rotation speed according to the impact force of the raw materials, improving the unloading efficiency.

[0013] 2. The present application can clean the surfaces of the plow plate main body and the conveyor belt through the moving groove, the threaded rod, the support rod, the turntable and the scraper. When the first motor is started, it drives the threaded rod to rotate, causing the support rod to drive the scraper to move together. During the movement of the scraper, it will scrape the surfaces of the plow plate main body and the conveyor belt, scraping off the attached raw materials. And when the support rod moves to both ends of the moving groove, after the second motor is started, it will drive the turntable to rotate, causing the turntable to drive the scraper to rotate to the rear side of the plow plate main body, so as to avoid obstruction caused by the scraper during the unloading process and improve the unloading efficiency.

Detailed Embodiment

[0020] In order to make the technical means, creative features, achieved objectives and functions of the present utility model easy to understand, the following will be further elaborated in combination with specific embodiments.

[0021] As Figure 1 and Figure 3 shown, an efficient belt conveyor unloader includes an unloader main body 1, a plow plate main body 2, a moving groove 9 and a scraper 16. A groove 201 is formed on the front surface of the plow plate main body 2. A number of rotating rollers 3 are evenly rotatably connected between the upper and lower surfaces of the groove 201, and a conveyor belt 4 is drivingly connected to the surface of the rotating roller 3. The two ends of the rotating roller 3 are very smooth and can rotate very easily.

[0022] As Figure 2As shown, one side of the scraper 16 facing the conveyor belt 4 is in contact with the surface of the conveyor belt 4. A leakage hole 5 is formed through the bottom of the groove 201 between the rotating rollers 3. The leakage hole 5 can leak out the raw materials that slide into the groove 201 to prevent accumulation. The bottom of the scraper 16 and the bottom of the plow body 2 are located on the same horizontal plane. The scraper 16 can scrape the surfaces of both the plow body 2 and the conveyor belt 4 simultaneously, so as to keep them smooth and facilitate the unloading of raw materials.

[0023] As Figure 3 shown, a support groove 6 is fixedly connected to the surface of the plow body 2 on the opposite side of the groove 201. A number of shock absorbers 8 are evenly fixedly connected to the outer side wall of the support groove 6. The other end of the shock absorber 8 is fixedly connected to the buffer plate 7. A moving groove 9 is horizontally slidably connected to the inside of the support groove 6. The moving groove 9 can slide out of the support groove 6 during maintenance and repair, and the installation and disassembly are relatively convenient. The inner side wall of the moving groove 9 is attached to the surface of the buffer plate 7. The moving groove 9 and the buffer plate 7 are connected by a fixing bolt 10 in a threaded manner. The fixing bolts 10 are located on the outer surfaces of the left and right ends of the moving groove 9. The shock absorbers 8 can dissipate the impact force received by the impact of the raw materials during the unloading process to prevent damage to the motor.

[0024] As Figure 4 shown, a threaded rod 11 is rotatably connected to the inside of the moving groove 9. A support rod 13 is threadedly connected to the surface of the threaded rod 11. The inner bottom surface of the rotating groove 141 formed above the side wall of the support rod 13 is rotatably connected to a turntable 14. The outer surface of the turntable 14 is fixedly connected to the scraper 16. The turntable 14 can rotate under the drive of the second motor 15, so as to drive the scraper 16 to rotate to the rear side of the plow body 2, thus not affecting the normal unloading.

[0025] As Figure 4 shown, a first motor 12 is fixedly connected to the outer side wall of the moving groove 9 towards one end of the threaded rod 11. The outer end of the transmission shaft of the first motor 12 is fixedly connected to the corresponding end of the threaded rod 11. The top end of the support rod 13 is fixedly connected to a second motor 15. The outer end of the transmission shaft of the second motor 15 is fixedly connected to the center of the top of the lower turntable 14.

[0026] During actual use, after the main body 11 of the unloader is installed, the main body 2 of the plow plate contacts the conveyor belt driven by the electric push rod, and then the unloading operation can start. When the raw materials hit the main body 2 of the plow plate, they will slide out from the surface of the conveyor belt. During this process, through the groove 201, the rotating roller 3 and the conveyor belt 4, the unloading can be assisted. After the raw materials hit the conveyor belt 4, the conveyor belt 4 will rotate driven by the rotating roller 3, carrying the raw materials to slide out of the conveyor belt better, so as to reduce the friction of the raw materials on the main body 2 of the plow plate, and can continuously change the rotation speed according to the impact force of the raw materials, improving the unloading efficiency. At the same time, through the moving groove 9, the threaded rod 11, the support rod 13, the turntable 14 and the scraper 16, the surfaces of the main body 2 of the plow plate and the conveyor belt 4 can be cleaned. The first motor 12 starts to drive the threaded rod 11 to rotate, so that the support rod 13 drives the scraper 16 to move together. During the movement of the scraper 16, it will scrape the surfaces of the main body 2 of the plow plate and the conveyor belt 4, scraping off the attached raw materials. And when the support rod 13 moves to both ends of the moving groove 9, the second motor 15 starts to drive the turntable 14 to rotate, so that the turntable 14 drives the scraper 16 to rotate to the rear side of the main body 2 of the plow plate, thus avoiding the obstruction caused by the scraper 16 during the unloading process and improving the unloading efficiency.

[0027] It should be noted that the belt conveyor unloader is a well-known device that can be directly purchased on the market. The present invention is an improvement in the structure and function of the plow plate for unloading, and there are not many changes in the rest of the structure and principle, so it will not be described in detail here.
