Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a lining plate for a material discharge chute. Background Art

[0002] The lining of traditional material discharge chute is made of wear-resistant steel plate. The material directly contacts the lining during the falling process, causing wear of the lining. This is especially true for large pieces of material. Due to their heavy weight and high hardness, the impact force on the lining when falling is large, which accelerates the wear of the lining and greatly reduces the service life of the lining. The lining needs to be replaced in a timely manner, which increases costs and workload.

[0003] A wavy, impact-resistant, and wear-resistant lining for use in a chute for bulk materials (document number CN215158034U). The disclosed technical solution includes a lining body, a steel base plate, welding bolts, and fixing nuts. The outer side surface of the lining body is designed to be wavy and serrated. The wavy and serrated lining body is arranged and installed facing the direction in which the material in the chute slides downward. In this document, the wavy and serrated lining body is arranged at an angle, and the material that has just entered the tooth valley can easily slide out of the tooth valley, which not only aggravates the wear at the tooth valley, but also reduces the effect of material abrasion. Utility Model Content

[0004] The purpose of the utility model is to provide a lining plate for a material discharge chute, so as to reduce the wear of the material on the lining plate.

[0005] The utility model can be realized through the following technical solutions: a material discharge chute lining, a corrugated lining is arranged on the wall surface along which the material slides down in the chute, the corrugated lining includes a base plate attached to the inner wall of the chute in an inclined state, and raised units are arranged on the base plate, and the raised units are arranged in a strip or ring shape along the circumferential direction at the same height position, the height of the upper edge where the raised unit is connected to the base plate is lower than the highest position of the raised unit, and a groove for accommodating material is formed between the two adjacent raised units in the upper and lower positions.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] The material is blocked by the raised unit surface between the upper edge and the highest position, making it difficult for the material to fall from the groove. When the material accumulates in the groove, a protective layer will be formed in the groove. When the material passes through this part, it can achieve the effect of material abrasion, thereby reducing the wear of the material on the liner. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Example 1

[0013] See also Figure 1-2 As shown, a material discharge chute liner, wherein a corrugated liner 10 is arranged on the wall surface along which the material in the chute 20 flows downward, is characterized in that: the corrugated liner 10 includes a base plate 11 attached to the inner wall of the chute 20 in an inclined state, and a protrusion unit 12 is arranged on the base plate 11. The protrusion units 12 are arranged in a strip or ring shape along the circumferential direction at the same height position, and the height of the upper edge 121 where the protrusion unit 12 connects to the base plate 11 is lower than the highest position 122 of the protrusion unit 12. A groove A for accommodating material is formed between two adjacent protrusion units 12 at the upper and lower positions;

[0014] In the above, the groove A is arranged along the circumferential direction of the chute 20. After the material enters the chute, part of the material slides along the surface of the corrugated lining 10. In this process, some fine materials will enter the groove A. Since the height of the upper edge 121 where the raised unit 12 is connected to the base plate 11 is lower than the highest position 122 of the raised unit 12, the surface of the raised unit 12 between the upper edge 121 and the highest position 122 blocks the material, making it difficult for the material to fall from the groove A. When the material accumulates in the groove A, a protective layer will be formed at the groove A. When the material passes through this part, it can achieve the effect of material abrasion, thereby reducing the wear of the liner by the material.

[0015] The upper and lower adjacent raised units 12 are arranged at intervals; this makes the groove A have a larger groove width in the downward direction of the material, so that the groove A can accommodate materials with larger particles. This arrangement is suitable for situations where there are fewer finely divided materials, so that materials with larger particles can also enter the groove A, and a protective layer is formed at the groove A to reduce the wear on the corrugated lining plate 10.

[0016] The base plate 11 is connected to the chute 20 by screws 30 ; when the corrugated lining plate 10 needs to be replaced, it is only necessary to unscrew the screws 30 from the outside of the chute, and then replace the new corrugated lining plate 10 , and use the screws 30 to achieve the connection between the base plate 11 and the chute 20 .

[0017] The cross-sectional profile of the raised unit 12 is in the shape of a flat-convex wing as a whole; this makes the surface of the raised unit 12 smooth, which is conducive to the downward sliding of the material.

[0018] Example 2

[0019] See also Figure 3-4 As shown, a discharge chute lining is different from Example 1 in that the upper and lower adjacent raised units 12 are arranged in close proximity and spaced apart; this arrangement is suitable for situations where the material contains a large amount of finely divided materials. When the discharged material contains a large amount of finely divided materials, the finely divided materials will accumulate in the groove A, and a protective layer will be formed at the groove A to reduce the wear on the corrugated lining 10.
