Adjustable pre-tightening oil sweeper

The adjustable pre-tightening sweeper is when the belt is found in operation occasionally because the sweeper and the belt tight degree is not suitable to cause the sweeper to remove coal, in the case of non-stop belt, a sweeper that can be adjusted by means of an artificial rotation at a certain angle. The adjustable pre-tightening sweeper mainly has the operation handle, the connecting rod, the rotary outer ring, the gear, the inner gear sleeve, the fixed tensioning sleeve, the left end shaft, the right end shaft. The belt pressure plate, the rubber belt, the spring, the pressure bearing, the fixed channel steel and so on constitutes. The selection of material for each part of the sweeper can be determined according to the conditions. The diameter size of the connecting part should be equal to the size of the internal groove of the tip steel so that it can be closely adhered to the internal groove of the channel steel, so that the concentricity of the two shaft heads can be ensured during installation. For ease of installation. In both ends of the shaft sleeve outside the processing of a fixed plate, and the sleeve outside, the gap to be moderate, so that it can be free to slide as * * * * * * , when the location is determined and then welded firmly, so that easy to ensure the two ends of the shaft sleeve concentricity.
