Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a refractory brick conveyor. Background Art

[0002] Refractory bricks are a kind of building material for kilns and are often used in buildings in the high-temperature calcination industry. During the processing and production of refractory bricks, conveyors are usually required to transport the refractory bricks. At present, most conveyors usually use rollers to directly transport refractory bricks. However, due to the hard and brittle characteristics of refractory bricks, refractory bricks are prone to defects after colliding with rollers during transportation, affecting product yield and thus affecting overall production efficiency. In addition, when encountering large refractory bricks, the conveying efficiency is easily reduced due to insufficient friction, affecting the conveying efficiency of the entire production line.

[0005] A further improvement is that the positioning device includes: a plurality of first positioning ring grooves opened on the active roller, a plurality of second positioning ring grooves opened on the driven roller and corresponding to the first positioning ring grooves, the friction belt is wound around the active roller and the driven roller and is located in the first positioning ring groove, and the thickness of the friction belt is greater than the depth of the first positioning ring groove and the second positioning ring groove.

[0006] A further improvement is that the friction belt is a seamless canvas belt.

[0007] A further improvement is that the driving device includes: a double-tooth transmission sprocket arranged on one end of the active roller, a reduction gear box arranged on the frame, and a servo motor fixedly arranged on the reduction gear box and connected to the input shaft of the reduction gear box, a driving sprocket is arranged on the output shaft of the reduction gear box, the driving sprocket is connected to the double-tooth transmission sprocket at the end of the frame through a first transmission chain, and any double-tooth transmission sprocket is connected to any double-tooth transmission sprocket closest to it through a second transmission chain.

[0008] A further improvement is that: the frame is also provided with an adjustment device for adjusting the tightness of the friction belt.

[0009] Further improvements are as follows: The adjustment device includes two tensioning seats arranged at the end of the frame, strip-shaped holes opened on the tensioning seats, and a roller shaft that can be slidably arranged in the strip-shaped holes through a sliding device. A transition roller is rotatably arranged on the roller shaft.

[0010] Further improvements are as follows: The sliding device includes a screw arranged in the strip-shaped hole, a positioning hole opened on the roller shaft for the roller shaft to slide on the screw, and positioning nuts locked on both sides of the roller shaft on the screw.

[0011] Further improvements are as follows: A number of vertical seat bearings with corresponding axes are arranged on the left and right sides of the frame. Both the driving roller and the driven roller are arranged in the inner rings of the vertical seat bearings.

[0012] Further improvements are as follows: A safety railing for preventing large refractory bricks from tipping over is also arranged on the frame.

[0013] Further improvements are as follows: A number of flow strips are also arranged on at least one side of the safety railing to convert the frictional force during the conveying collision of refractory bricks.

[0014] The advantages and beneficial effects of the present utility model are as follows:

[0015] The structure is simple and convenient to use. It is cross-arranged on the driving roller and the driven roller. While enhancing the pressure-bearing conveying capacity of the conveyor, it can also reduce the overall cost of the conveyor. Moreover, a friction belt with tensile strength and wear resistance is wound around it, which can further improve the conveying efficiency of large refractory bricks, avoid slipping due to insufficient frictional force, enhance the convenience of using the conveyor, and at the same time prevent the refractory bricks from directly hitting the roller to generate impact, protecting the roller and the refractory bricks.
