Description

TECHNICAL FIELD

[0001] The utility model relates to the field of mine scraper conveyor, in particular to a split type scraper assembly. BACKGROUND

[0002] The scraper assembly is the main conveying component of the mine conveyor, is the vulnerable component, needs to be replaced when the serious abrasion or the fracture occurs in the use process of a certain tonnage coal quantity, the existing scraper assembly is the structure that the scraper is connected with the pressing plate, wherein the scraper occupies the weight of the vast majority of the scraper assembly, and the weight of the pressing plate is particularly light. Two people are needed to carry the scraper to replace the scraper assembly. Therefore, it is necessary to design a structure that the weight of a single component is not large, and one person can complete the replacement of the scraper assembly, which can save labor and reduce labor intensity. SUMMARY

[0003] Therefore, the utility model aims at providing a split type scraper assembly to solve the problems in the background art.

[0004] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0005] A split type scraper assembly, comprising an upper scraper and a lower scraper, the weight difference between the upper scraper and the lower scraper is not large, the upper scraper is provided with a boss, the lower scraper is provided with a groove, and the upper scraper and the lower scraper are positioned through the boss and the groove.

[0006] Preferably, a plurality of through holes are arranged on the upper scraper and the lower scraper, and the upper scraper and the lower scraper are connected together through special-shaped bolts and lock nuts.

[0007] Compared with the prior art, the utility model has the following advantages:

[0008] (1) The split type scraper assembly can save labor and reduce labor intensity by one person carrying the upper scraper and the lower scraper with little weight difference.

[0009] (2) The boss of the upper scraper and the groove of the lower scraper cooperate to make the scraper assembly very stable on the chain, reduce the skew phenomenon of the scraper assembly on the chain, and meet the conveying demand. BRIEF DESCRIPTION OF DRAWINGS

[0018] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the description of the present application, the structures, proportions, sizes, etc. shown in the drawings attached to the present specification are merely used to cooperate with the content disclosed in the present specification, to be understood and read by those skilled in the art, and are not used to limit the implementation conditions of the present application, so they do not have technical substantive significance. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the functions and purposes that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application. At the same time, the terms such as "upper", "lower", "left", "right", "middle", and "one" used in the present specification are merely for the convenience of understanding and clarity of description, and are not used to limit the scope of the embodiments of the present application. The change or adjustment of the relative relationship, without substantially changing the technical content, is also considered as the scope of the embodiments of the present application.

[0020] The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0021] The present embodiment relates to a split type scraper plate assembly, such as Figures 1-5As shown, including the upper scraper 1 and the lower scraper 2, here need to mention, the upper scraper 1 and the lower scraper 2 are not much different in weight, the upper scraper 1 is provided with a boss 5; The lower scraper 2 is provided with a groove 6, and a plurality of through holes are formed in the upper scraper 1 and the lower scraper 2; under the positioning action of the boss 5 and the groove 6, cooperate with the plurality of through holes arranged on the upper scraper 1 and the lower scraper 2, connected into an integrated body through the special-shaped bolt 3 and the lock nut 4, under the cooperation of the boss 5 of the upper scraper 1 and the groove 6 of the lower scraper 2, the scraper assembly is very stable on the chain, reduces the skew phenomenon of the scraper assembly on the chain. Can meet the conveying demand.

[0022] When the material conveying and cleaning system runs for a period of time, the scraper assembly is worn to a certain extent or the scraper assembly is broken due to long-time friction with the material. At this time, only one maintenance personnel is needed to use a wrench to unscrew the lock nut 4, pull out the special-shaped bolt 3, then disassemble the worn upper scraper 1 and lower scraper 2, carry the new upper scraper and lower scraper to the installation position, position through the boss 5 and the groove 6, and then connect the special-shaped bolt 3 and the lock nut 4, so as to quickly complete the replacement of the scraper assembly. The whole replacement process takes a short time, greatly saves the labor and time cost, reduces the labor intensity, and ensures the efficient and stable operation of the material conveying and cleaning system.

[0023] The above only describes the preferred embodiment of the present application, and does not limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
