Description

Technical Field

[0001] The utility model belongs to the field of conveying equipment, in particular to a cleaning device used for conveying equipment. Background Art

[0002] With the development of industrial equipment, various industries in society have applied various conveying equipment such as belt conveyors and scraper conveyors. In the application of conveying equipment, the material bearing plate / belt is the main component, which is easy to stick to the material during operation, especially in the conveying of sticky and wet materials. The cleanliness of the bearing plate during operation is the guarantee of stable and reliable operation of the conveying equipment. There are also many cleaning devices in the application places of conveying equipment. At present, most of the cleaning devices used are cylindrical smooth cylinders, which rely on the friction when contacting with the material or remove the material by reducing the space. This method can play an effective role in some occasions, but the gap between the cleaning device and the bearing plate / belt cannot be infinitely small. In the conveying of highly viscous materials, this cleaning device often squeezes the material into a cake shape with the conveying bearing plate / belt, which aggravates the sticking of the bearing plate / belt. Especially in high-cold areas, when the temperature is low, the sticky and wet material cake freezes quickly, and the frozen layer will become thicker and thicker, and the bonding strength will become greater and greater. The traditional cleaner is easy to be damaged. The bearing plate / belt of the conveying equipment has a poor conveying efficiency due to the increase in load, and the equipment is also easy to be damaged. Utility Model Content

[0036] A transmission fixed shaft 1 is respectively provided on the end surfaces of both ends of the cylinder 2, and the transmission fixed shaft 1 is fixedly connected to the cylinder 2 by a fastener 6;

[0037] The transmission fixed shaft is then connected to the output end of the motor 7 through a coupling 8 or a limiter to drive the cylinder 2 to rotate. Figure 4 shown.

[0038] Preferably, a bearing assembly 4 is provided on the transmission fixed shaft 1, and the bearing assembly 4 is connected to the fixed shaft via a clamping sleeve 5. The bearing assembly 4 can reduce friction and increase the rotation speed; and different working conditions can be responded to by setting the clamping sleeve 5.

[0040] Preferably, a heating plate 22 is provided on the inner surface of the cylinder 2, and the heating plate 22 is in a mesh, spiral or sheet shape. When the temperature is low, turning on the heating plate 22 can improve the cleaning efficiency.

[0041] Preferably, the mounting holes 21 are distributed in groups, divided into three groups, each group is distributed along the axis of the cylinder 2; the three circumferential groups of mounting holes 21 are spaced 120° apart from each other; preferably, the number of mounting holes 21 in each group is 8, so as to fully contact with the material bonding layer of the supporting plate / belt as much as possible to clean it and improve the cleaning efficiency.

[0042] Preferably, the mounting hole 21 is a wedge-shaped hole, and the scraper 3 is mounted in the wedge-shaped hole to achieve self-locking fixation.
