[0002] Scraper conveyor is a continuous conveying equipment that pushes materials with the help of scraper chain movement. It is mainly used for transporting coal in coal mining working faces and mining tunnels in coal mines. Its main components include: head, body, tail, scraper chain, drive device, chain tightening device, push device, coal baffle, chute, etc. The motor drives the scraper chain to do circular motion in the chute through the drive device, pushing the material from the tail to the head, and then unloading the material from the head. During the operation of the scraper conveyor, the chain will relax due to wear and temperature changes, causing the chain to jump and the scraper to tilt.

[0003] The existing scraper conveyor is connected to both sides of the sprocket shaft by adjusting bolts. During the process of adjusting the tension of the sprocket, it is necessary to use a tool to rotate the nuts on the adjusting bolts at both ends so that the adjusting bolts drive the two sides of the sprocket shaft to move horizontally, thereby adjusting the tension of the sprocket on the scraper conveyor. This will result in the need to use the tool to rotate the nuts on the adjusting bolts multiple times during the adjustment process, resulting in cumbersome sprocket tension adjustment steps, which takes a lot of time and affects work efficiency.

[0028] Embodiment 1

[0029] As Figures 1 to 3 shown, a sprocket tensioning device and a scraper conveyor proposed by this utility model include: a conveying channel 1; a first shaft rod 2 and a second shaft rod 3 rotatably arranged inside the conveying channel 1, and the first shaft rod 2 and the second shaft rod 3 are located on the same horizontal plane. A set of first sprockets 4 are sleeved on the outer walls of the first shaft rod 2 and the second shaft rod 3 respectively, and the first sprockets 4 are symmetrically arranged; symmetrically arranged chutes 5 are opened on the inner wall of the conveying channel 1. Sliders 6 are slidably arranged inside the chutes 5. A third shaft rod 7 is rotatably arranged between the sliders 6, which can guide the third shaft rod 7 to make the third shaft rod 7 more stable during movement. A set of second sprockets 8 are sleeved on the outer wall of the third shaft rod 7, and the second sprockets 8 are symmetrically arranged. A chain 9 is arranged between the second sprockets 8 and the first sprockets 4. A scraper 10 is fixedly arranged between the chains 9, and a plurality of scrapers 10 are arranged. The scraper 10 is arranged in an "L" shape structure, which is convenient for loosening the materials; an adjusting component 11 for adjusting the sprocket tension is arranged between the first shaft rod 2 and the third shaft rod 7, which can quickly and conveniently adjust the tension degree of the sprockets.

[0030] As Figures 2 to 4 shown, the adjusting component 11 includes a socket block 111 movably sleeved on the outer wall of the first shaft rod 2 and a fixed block 112 movably sleeved on the outer wall of the third shaft rod 7. One side of the fixed block 112 is inclined. A guiding groove 113 is opened on the inclined side of the fixed block 112. One side of the socket block 111 is fixedly connected with a mounting frame 114, and the mounting frame 114 is arranged in a "C" shape structure. A threaded adjusting rod 115 is rotatably arranged between the mounting frames 114 through a bearing, and one end of the threaded adjusting rod 115 is fixedly connected with a hand wheel for convenient manual rotation. An adjusting block 116 is threadedly sleeved on the outer wall of the threaded adjusting rod 115. One side of the adjusting block 116 is inclined and can fit more closely with the inclined side of the fixed block 112. A guiding block 117 is fixedly arranged on the inclined side of the adjusting block 116. The guiding block 117 is slidably connected with the guiding groove 113, which can improve the connection stability between the fixed block 112 and the adjusting block 116, and at the same time facilitate pushing the fixed block 112 to move horizontally, so as to more stably adjust the tension degree of the sprockets.

[0031] Furthermore, a limiting groove 12 is opened on one side of the mounting frame 114, and a limiting block 13 is fixedly arranged on one side of the adjusting block 116. The limiting block 13 is slidably connected to the limiting groove 12, which can guide the adjusting block 116 to make its movement more stable and improve the stability of the sprocket tensioning.

[0032] Secondly, a feed port 14 is provided on one side of the upper surface of the conveying channel 1, and a collecting hopper 15 is fixedly installed on the upper side of the feed port 14, which is convenient for adjusting the material for conveying to the inside of the conveying channel 1; a discharge port 16 is provided on one side of the bottom surface of the conveying channel 1, and a guide hopper 17 is fixedly installed on the lower side of the discharge port 16, which is convenient for guiding and discharging the conveyed material.

[0033] Furthermore, the guide groove 113 and the guide block 117 are arranged in a triangular structure, which can stably engage the fixing block 112 and the adjusting block 116, making the connection more stable and making the adjusting block 116 push the fixing block 112 more stably.

[0034] In addition, the limiting groove 12 and the limiting block 13 are arranged in a "convex"-shaped structure, which can guide and limit the adjustment block 116 during the horizontal movement, making its movement more stable.

[0035] Finally, the sizes of the first sprocket 4 are different, and the size of the first sprocket 4 sleeved on the first shaft 2 is smaller than the first sprocket 4 sleeved on the second shaft 3, so as to avoid the first sprocket 4 on the first shaft 2 generating resistance to the chain 9, thereby making it easier to adjust the tension of the chain 9.

[0036] Embodiment 2

[0037] like Figures 1 to 4 As shown, based on the first embodiment, the utility model further discloses a scraper conveyor, including the above-mentioned scraper conveyor sprocket tensioning device.

[0038] The working principle of this embodiment is as follows: when a scraper conveyor sprocket tensioning device in the utility model is actually used, firstly, the handwheel at one end of the threaded adjusting rod 115 is manually rotated to make the threaded adjusting rod 115 drive the adjusting block 116 to move horizontally, and the adjusting block 116 drives the limit block 13 to slide horizontally in the limit groove 12, which can improve the stability of the horizontal movement of the adjusting block 116.

[0039] Furthermore, the adjusting block 116 drives the guide block 117 to slide horizontally in the guide groove 113, which not only increases the stability of the movement of the adjusting block 116 and the fixed block 112, but also makes the connection between the adjusting block 116 and the fixed block 112 more stable. The adjusting block 116 pushes the fixed block 112 to move horizontally, and the fixed block 112 drives the third shaft rod 7 to move horizontally. The third shaft rod 7 drives the sliders 6 at both ends to slide horizontally in the slide groove 5, making the movement of the third shaft rod 7 more stable.

[0040] Furthermore, the third shaft 7 drives the second sprocket 8 to move horizontally, and the second sprocket 8 drives the chain 9 to move, so that the tension of the chain 9 can be adjusted conveniently and quickly, and the adjustment steps are simple, thereby reducing the time consumed in adjusting the tension of the scraper conveyor sprocket and improving work efficiency.

[0041] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
