DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] The directions "vertical", "horizontal", "longitudinal", "up", "down", "left", "right" and so on used in this utility model are all in their respective positions in use. Figure 1 The following is based on the attached Figure 1The orientation or positional relationship shown is only for the convenience of describing the present invention, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0018] Coal sweeping device for belt guide roller, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes a base 1 and a receiving trough 2; the receiving trough 2 includes a scraping side plate 21, a receiving bottom plate 22 and a blocking side plate 23; the bottom end of the scraping side plate 21 is fixed to one side of the receiving bottom plate 22, and the top end extends longitudinally upward and obliquely to the left; the bottom end of the blocking side plate 23 is fixed to the other side of the receiving bottom plate 22, and the top end extends longitudinally upward and obliquely to the right; a trapezoidal groove extending along the axial direction of the guide roller is formed by the scraping side plate 21, the receiving bottom plate 22 and the blocking side plate 23. ; A scraper 3 is installed at the top of the scraping side plate 21. The scraper 3 is made of rubber. The scraper 3 extends from one end of the scraping side plate 21 to the other end, and the scraper 3 includes a mounting section and a scraping section along the vertical direction. The mounting section of the scraper 3 is connected to the scraping side plate 21, and the scraping section of the scraper 3 exceeds the top edge of the scraping side plate 21; the two ends of the guide roller 4 are supported on the base 1, and the receiving bottom plate 22 of the receiving trough 2 is supported on the base 1, and the scraping section of the scraper 3 is in close contact with the guide roller 4.

[0019] The utility model discloses a coal sweeping device for a belt guide roller. The base 1 is used to assemble a receiving trough 2 and a guide roller 4, typically using the guide roller 4's own mounting base. A scraper 3 is provided on the scraping side plate 21 of the receiving trough 2 to sweep coal sludge and other materials from the guide roller 4 and collect them into the trough of the receiving trough 2. Firstly, the coal sludge and other materials on the guide roller 4 are effectively removed, which helps reduce the probability of belt conveyor failure. Secondly, the cleaned coal sludge and other materials fall into the receiving trough 2. The receiving trough 2 is positioned next to the bottom of the guide roller 4, making it easier to clean the coal sludge scraped from the guide roller 4. The inclined arrangement of the scraping side plate 21 facilitates the guidance of the coal sludge and other materials into the trough. The rubber scraper 3 also helps prevent scratches on the guide roller 4.

[0020] In order to facilitate the replacement of the scraper 3, the installation section of the scraper 3 is connected to the scraping side plate 21 by bolts.

[0021] In this embodiment, the “transverse direction” is also the direction that is consistent with the axial direction of the guide roller 4 after the guide roller 4 is horizontally arranged; and the “longitudinal direction” is the direction perpendicular to both the transverse direction and the vertical direction.

[0022] During use, the scraper 3 has the problem of wear. In order to make the scraper 3 always in close contact with the guide roller 4 by adjusting the receiving trough 2 as the scraper 3 wears, so as to effectively clean the guide roller 4, preferably, the receiving bottom plate 22 of the receiving trough 2 is movably adjusted along the longitudinal direction and installed on the base 1.

[0023] The guide adjustment can be performed by setting a slide rail and slide groove structure between the receiving trough 2 and the base 1. In order to simplify the structure, a long hole 24 extending longitudinally is provided on the receiving bottom plate 22, and a circular mounting hole 11 is provided on the base 1. The limiting bolt 5 passes through the long hole 24 and the mounting hole 11 to install the receiving bottom plate 22 on the base 1.

[0024] In order to facilitate the movement of the receiving trough 2, an adjusting mechanism 6 is provided on the base 1 for pushing the receiving trough 2 longitudinally toward the side where the guide roller 4 is located to adjust the position of the receiving trough 2.

[0025] The adjustment mechanism 6 can be a hydraulic rod, etc. In this embodiment, the adjustment mechanism 6 includes an adjustment bolt 61, an adjustment nut 62, a limit nut 63, a push spring 64, a first lug 65, and a second lug 66. The first lug 65 is fixed to the base 1, and the second lug 66 is fixed to the receiving trough 2. The first lug 65 and the second lug 66 are arranged in a row along the longitudinal direction. The adjustment bolt 61 passes through the through holes of the second lug 66 and the first lug 65 in sequence. At least two limit nuts 63 are threadedly connected to the adjustment bolt 61, and the two limit nuts 63 relatively clamp the first lug 65. The adjustment nut 62 is threadedly connected to the adjustment bolt 61 and is located between the first lug 65 and the second lug 66. The push spring 64 is sleeved on the adjustment bolt 61 and is located between the adjustment bolt 61 and the second lug 66. The adjustment mechanism 6 disclosed in this embodiment is a mechanical connection, simple in structure, and low in manufacturing and use costs.

[0026] Only one set of adjustment mechanism 6 can be provided to act on the corresponding position in the middle of the receiving trough 2 for adjustment. In this embodiment, preferably, there are two sets of adjustment mechanism 6, and the two sets of adjustment mechanism 6 are arranged side by side along the receiving trough 2.

[0027] The present invention discloses a coal sweeping device for a belt guide roller. When the belt is running, the guide roller 4 rotates accordingly. The scraper 3, made of wear-resistant rubber on the scraping side plate 21 of the receiving chute 2, is in close contact with the surface of the guide roller 4, cleaning the coal sludge on the tail guide roller 4. As the scraper 3 wears, the push spring 64, under the action of thrust, pushes the receiving chute 2 toward the guide roller, ensuring that the scraper 3 always maintains close contact with the tail guide roller 4. When the push spring 64 reaches the end of its travel and can no longer move the receiving chute toward the guide roller and press it against the tail roller 4, the adjusting nut 62 on the device is adjusted to compress the push spring 64, storing energy. Under the action of the spring, the receiving chute 2 moves toward the guide roller again, pressing the scraper 3 against the surface of the tail roller 4. If the scraper 3 is worn to the point of exhaustion after a period of use, it is replaced.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
