Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of screening machines, especially a scraping device for a screening machine. BACKGROUND

[0002] A screening machine is a vibrating screening mechanical device that uses the relative movement of granular materials and a screen surface to make part of the particles pass through the screen holes, and divide sand, gravel, and other materials into different levels according to particle size. The screening process of a screening machine is generally continuous. After the raw materials are fed into the screening machine (referred to as a screen), the materials smaller than the size of the screen holes pass through the screen holes, which are referred to as undersize products. The materials larger than the size of the screen holes are continuously discharged from the screen surface, which are referred to as oversize products. During operation, the screening machine often needs to use a scraping device. The existing scraping device has a mud scraping tooth corresponding to the screening roller, which can only be adjusted up and down and cannot be adjusted left and right. However, due to the processing error, the subsequent installation process may cause the horizontal mud scraping tooth to be unable to be completely installed, which requires manual reprocessing of the mud scraping tooth to facilitate the overall installation of the mud scraping tooth. Although this operation can achieve the purpose, the efficiency is relatively low, the use effect is not good, and it cannot meet the long-term processing needs of enterprises.

[0003] In view of the above situation, it is necessary to improve the existing screening machine scraping device to adapt to the needs of the screening machine scraping. SUMMARY

[0004] To achieve the above-mentioned purpose, the technical scheme of the utility model is a scraping device for a screening machine, which comprises a shell, a screening roller arranged on the shell, and a mud scraping device arranged on the shell below the screening roller. The mud scraping device comprises a mounting bracket and a plurality of mud scraping plates arranged on the mounting bracket. The two ends of the mounting bracket are fixedly installed on the shell by bolts. A square steel plate is protrudingly arranged on one side of the mud scraping plate close to the mounting bracket. A square groove is arranged on the mounting bracket. The square steel plate is installed in the square groove. The mud scraping plate and the mounting bracket are connected by a plurality of bolts.

[0005] Further supplement to the technical scheme, four mounting holes are arranged on the mud scraping plate. A runway-shaped groove is arranged on the mounting bracket corresponding to the position of the mounting hole. The bolt passes through the mounting hole, the runway-shaped groove, and the shell to be connected and fixed.

[0006] Further supplement to the technical scheme, the length of the runway-shaped groove is greater than the diameter of the mounting hole.

[0007] Further supplement to the technical scheme, the width and length of the square groove are greater than the width and length of the square steel plate.

[0008] Further supplement to the technical scheme, the distance between adjacent mud scraping devices is equal.

[0009] Its beneficial effect lies in, the mud tooth can adjust left and right, also can adjust up and down, can eliminate certain error, installation and removal is convenient, use effect is good, it is convenient for enterprise to use. BRIEF DESCRIPTION OF DRAWINGS
