Embodiment Construction
[0010] Such as figure 2 As shown, the installation structure of the tail wheel tensioning slide plate of the bucket elevator includes a tail wheel shaft 1 and a side plate 2 of the body. On the bearing seat 4, a tensioning slide plate 5 is arranged on the inner side of the body side plate 2, the inner hole of the tensioning slide plate 5 is in sealing contact with the tail wheel shaft 1 through a seal, and a gasket is placed between the tensioning slide plate 5 and the body side plate 2 6. The edge of the tensioning slide plate 5 is axially limited by the pressure plate 7, and the pressure plate 7 is pressed tightly by the bolt 8 pierced on the side plate of the body; the inner end of the bolt 8 is pressed on the pressure plate 7, and the bolt 8 The outer end is pressed on the outside of the body side plate by a compression spring 9 that is enclosed within the bolt. The bearing seat 4 is limited by the limit groove 10 provided on the edge and the limit block 11 fixedly insta...

The invention relates to a part structure of a material conveying device, in particular to a mounting structure of a tensioning sliding plate of a bucket lifter tail wheel. The structure comprises a tail wheel rotary shaft and a machine body lateral plate, two ends of the tail wheel rotary shaft penetrate through mounting holes on the machine body lateral plate and then are mounted on external bearing seats through bearings, the tensioning sliding plate is arranged on an inner side of the machine body lateral plate, an inner hole of the tensioning sliding plate is in seal contact with the tail wheel rotary shaft through a seal piece, a sealing gasket is arranged between the tensioning sliding plate and the machine body lateral plate, edges of the tensioning sliding plate are axially limited by a compression plate, and the compression plate is tightly compressed by a bolt connected on the machine body lateral plate in a penetrating manner. An inner lateral end of the bolt is compressed on the compression plate, and an external lateral side of the bolt is compressed on an external side of the machine body lateral plate through a compression spring sleeved on the bolt. The mounting structure is simple in structure and easy to be achieved, gaps between the compression plate and the tensioning sliding plate can be compensated automatically, and accordingly sealing of a tail wheel mounting part is guaranteed and operation service life of the part is prolonged.
Description
technical field [0001] The invention relates to a component structure of material conveying equipment, in particular to a mounting structure of a tensioning slide plate for a tail wheel of a bucket elevator. Background technique [0002] The tail wheel of the bucket elevator is used to load and tension the conveying belt. The two ends of the tail wheel's rotating shaft pass through the mounting holes on the side plate of the machine body and are installed on the outer bearing seat through bearings. To meet the needs of tight adjustment, there is usually an adjustable installation structure between the tail wheel and the body, which requires an adjustable gap between the shaft of the tail wheel and the mounting hole on the side plate of the body, which affects the sealing of the mechanical action part, so usually A tension slide plate is arranged inside the installation hole of the body side plate. Its structure is usually as follows figure 1 As shown, the inner hole of the...
