Description

TECHNICAL FIELD

[0001] The present application relates to the field of belt ice breaking cleaning device, in particular to a belt ice breaking cleaning device. BACKGROUND

[0002] The belt machine is a belt conveying tool, which conveys the objects placed on the surface of the belt from one end to the other end through the combination of the roller and the belt. Due to the simple structure, low cost and high adaptability of the belt machine, the belt machine is widely used in short-distance transportation industry, such as loading and unloading of factories and wharfs.

[0003] When the belt machine is used to transport wet materials in winter, the belt will be frozen in a large area due to the low temperature, which may cause the belt to deviate and affect the material conveying. Therefore, the belt ice breaking cleaning device is proposed to solve the problem. SUMMARY

[0005] In view of the problems in the prior art, the purpose of the present application is to provide a belt ice breaking cleaning device. In the present application, the ice layer on the surface of the belt is removed by pressing the rollers. During the working process, the ice breaking roller presses the belt towards the two pressing rollers, the thread and the ice breaking roller extrude the belt to generate a shearing force, which breaks the ice layer on the surface of the belt and causes the ice layer to separate and fall off from the belt. At the same time, during the process of extruding the belt by the ice breaking roller and the pressing roller, the two pressing rollers rotate at a uniform speed. The rotating thread generates a cutting force and a pushing force on the ice layer on the surface of the belt, i.e. the edge of the thread cuts and shreds the ice layer by friction. Part of the ice (completely separated) directly falls off, and the other part (with adhesion) is pushed to the side along the thread. This method greatly improves the ice layer removal effect on the surface of the belt, reduces the ice layer residue on the surface of the belt, avoids the deviation of the belt under the influence of the ice layer, and is conducive to the smooth progress of the subsequent work.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present application are:

[0019] 1. The present application removes the ice layer on the surface of the belt by pressing the two compression rollers, in the working process, the ice-breaking roller presses the belt towards the two compression rollers, the thread and the ice-breaking roller extrude the belt to generate a shearing force, which breaks the ice layer on the surface of the belt and promotes the separation and falling of the ice layer, at the same time, in the process of extruding the belt by the ice-breaking roller and the compression roller, the two compression rollers rotate at a uniform speed, the rotating thread generates a cutting force and a pushing force on the ice layer on the surface of the belt, i.e. the edge of the thread rubs and cuts the ice layer, part of the broken ice (completely separated) directly falls off, and the other part (with adhesion) is pushed to the side along the thread, which greatly improves the cleaning effect of the ice layer on the surface of the belt, reduces the residual ice layer on the surface of the belt, avoids the deviation of the belt under the influence of the ice layer, and facilitates the smooth progress of the subsequent work.

[0020] 2. The thread on the outside of the compression roller is divided into two sections, and the screw directions of the two sections are opposite, and the pushing direction is left and right, so that the compression roller pushes the ice layer on the left side of the belt to the left side, and the ice layer on the right side of the belt to the right side, which improves the cleaning efficiency and improves the cleaning effect.

[0021] 3. The belt is pre-treated by two pre-pressure rollers. When the belt passes between the two pre-pressure rollers (the ice layer on the belt surface is in large pieces, and the belt enters straight due to the restriction of the ice layer), the pre-pressure rollers use the grid strips on their own surfaces to press the ice layer on the belt surface into a fine grid. This improves the deformation capacity of the belt and makes it easier for the belt to enter between the pressing roller and the ice-breaking roller. At the same time, the grid strips have multiple compression points with the belt. These compression points disperse the tearing force generated on the belt when the ice layer breaks (some ice layer is tightly adhered to the belt. When the ice layer breaks, the ice layer is misaligned at the break, but the belt below the break is still a whole, and tearing force will be generated here), reducing the damage to the belt and helping to extend the service life of the belt.

[0022] 4. By injecting air between the belt and the ice layer, during the process of the pre-compression roller squeezing the belt, the top pressure rod penetrates deep into the ice layer and rushes high-pressure air between the ice layer and the belt. This air will promote the separation of the belt and the ice layer. Through the cleaning effect on the belt surface, it also reduces the damage to the belt during the ice peeling process.

[0023] 5. When the push spring is compressed, the two annular grooves are misaligned; when the push spring is extended, the two annular grooves are aligned. When the top pressure rod contacts the hard ice layer, the top pressure rod is squeezed into the receiving groove, compressing the push spring. When the top pressure rod breaks through the ice layer and contacts the soft belt, the push spring pushes the top pressure rod out of the receiving groove. Air enters the annular groove through the connecting hole and finally is injected between the belt and the ice layer through the exhaust hole. The precise control of the air injection time avoids pressure leakage and also prevents air from being ejected too early, which would affect the separation effect. Attached Figure Description
