Description

Technical Field

[0001] The present invention relates to the technical field of belt conveyor cleaning, and particularly to a two-way coal scraper applicable to a belt that can run forward and backward. Background Art

[0002] In the process of coal transportation, belt conveyors are widely used. Belt conveyors play an extremely important role in the coal field and are key equipment indispensable in the process of coal production and transportation. Belt conveyors can achieve continuous and efficient transportation of coal, greatly improving the efficiency of coal production. Secondly, belt conveyors can adapt to the complex working environment underground in coal mines, such as harsh conditions like high temperature, high humidity, and dust. Moreover, belt conveyors have the characteristics of large conveying capacity and can meet the needs of large-scale coal production, making their application in the coal field have unique advantages.

[0003] When the belt on the belt conveyor carries coal and runs, coal particles will inevitably adhere to the surface of the belt. Therefore, a coal scraper for cleaning the coal powder on the belt needs to be set on the belt conveyor. Most of the existing coal scrapers are designed for one-way coal scraping, that is, they can only function when the belt runs in one direction. In some industrial scenarios, the belt needs to run forward and backward to meet different conveying requirements. At this time, the one-way coal scraper cannot adapt to the reverse operation of the belt, resulting in the ineffective scraping of the coal on the belt surface during the reverse operation. This will not only cause waste of coal, but also pollute the working environment. Even more, problems such as belt deviation and increased wear may occur due to coal residue, affecting the normal operation and service life of the belt conveyor. Summary of the Invention

One end of the toggle plate frame 31 extends towards the blade of the scraper member 3 and is parallel to the plane where the scraper member 3 is located. Cleaning scrapers 32 are connected to both sides of the toggle plate frame 31, and the blades of the cleaning scrapers 32 are in contact with the surface of the scraper member 3;

[0047] The cleaning assembly further includes two pipe frames 33 provided on the obliquely lower surface 20 of the tool rest 11. A lifting rod 330 is connected between the two pipe frames 33. A telescopic pipe 34 is sleeved on the lifting rod 330.

[0048] By providing the self-cleaning assembly, the scraper member 3 can be kept clean during long-term use, effectively avoiding the trouble caused by cleaning the scraper member 3, and the cleaning assembly is controlled by the controller 39, which is automated and reduces the cost of manual operation.

[0049] As Figure 5 shown in the figure, the control mechanism includes:

[0050] The controller 39 is connected to the support frame 2, and the controller 39 is electrically connected to the driving motor 404, the rotating motor 27, the oil pump 29, the water pump 37, and the vibration motor 22 respectively;

[0051] In order to identify the direction in which the conveyor belt 102 travels, a device plate 40, a direction wheel 42, two elastic bases 43, a guide rod 44, a telescopic spring 45, and a Hall sensor 46 are also provided on the device. Specifically, the device plate 40 is connected to the vertical plate 6, and a support base 41 is connected to the device plate 40; the direction wheel 42 is arranged at the bottom of the conveyor belt 102 and is in movable contact with the cleaning surface 103 of the conveyor belt 102; the two elastic bases 43 are rotatably connected to the direction wheel 42; one end of the guide rod 44 is connected to the elastic base 43, and the other end passes through the support base 41 and is slidably connected to the support base 41; there are two telescopic springs 45, which respectively correspond to the two elastic bases 43, and both ends of the telescopic spring 45 are connected to the elastic base 43 and the support base 41 respectively; the sensing end of the Hall sensor 46 faces the direction wheel 42 and is used to identify the rotation direction of the direction wheel 42. The Hall sensor 46 is a prior art structure and will not be elaborated in detail;

[0052] According to the different rotation directions of the direction wheel 42, corresponding electrical signals are respectively output by the Hall sensor 46. Then, the controller 39 electrically connected to the sensor will receive this signal, and the controller 39 will output a corresponding control signal according to the system settings. When the Hall sensor 46 detects through the direction wheel 42 that the conveyor belt 102 is traveling in the direction of direction one 201, it will transmit a corresponding signal to the controller 39, and the controller 39 will control the drive motor 404 located at the position of direction two 202 according to this signal, so that the scraper 3 deflects upward and the blade of the scraper 3 contacts the bottom of the conveyor belt 102. At this time, the blade of the scraper 3 can scrape and clean the pulverized coal attached to the conveyor belt 102. When the Hall sensor 46 detects through the direction wheel 42 that the conveyor belt 102 is traveling in the direction of direction two 202, it will transmit a corresponding signal to the controller 39, and the controller 39 will control the drive motor 404 located at the position of direction one 201 according to this signal, so that the scraper 3 deflects upward and the blade of the scraper 3 contacts the bottom of the conveyor belt 102. At this time, the blade of the scraper 3 can scrape and clean the pulverized coal attached to the conveyor belt 102.

[0053] The working principle and usage process of the present invention:

[0054] During use, first, the control mechanism identifies the traveling direction of the conveyor belt 102. When it is recognized that the traveling direction of the conveyor belt 102 is one of the direction one 201 or the direction two 202, a corresponding signal will be transmitted to the controller 39. The controller 39 will control the operation of the drive motor 404 located in the direction opposite to the traveling direction of the conveyor belt 102 according to this signal. Driven by the swing mechanism 4, the scraper member 3 deflects upward and the blade of the scraper member 3 contacts the bottom of the conveyor belt 102. Specifically, the drive motor 404 drives the driving gear 402 to rotate through the drive shaft 403, and then drives the driven gear 401 to rotate. The driven gear 401 drives the rotating shaft 8 to rotate. Then, the rotating shaft 8 drives the base 14, the force-bearing rod 16, the rotating base two 17, the adjusting screw 13, the compression spring 19, and the rotating base one 12 to drive the tool rest 11 to perform a rotational movement centered on the hinge frame 7. The scraper member 3 moves synchronously therewith, and the blade of the scraper member 3 gradually moves in the direction of the conveyor belt 102 until it contacts the cleaning surface 103 of the conveyor belt 102. At this time, the blade of the scraper member 3 can scrape and clean the pulverized coal attached to the conveyor belt 102. The setting of the two scraper members 3 can realize double-sided coal scraping of the conveyor belt 102.
