TECHNICAL FIELD

[0001] The utility model belongs to conveying equipment field relates to a scraper for scraper. BACKGROUND

[0002] As a kind of efficient material handling equipment, scraper conveyor is widely used in many industries. Its core components include driving device, chain (or belt), scraper, trough and tail tensioning device. When working, the chain or belt is driven by motor to run, and the scraper on the chain pushes the material along the bottom of the trough from one end to the other end, realizing the continuous conveying of the material. This conveying method is particularly suitable for the transportation of powdery or granular materials in coal, chemical, metallurgical and building material industries.

[0003] The scraper conveyor is favored mainly because of its simple structure, strong adaptability, high conveying efficiency and ability to convey horizontally or obliquely according to actual needs. Especially in the field of coal mining and processing, the scraper conveyor can effectively convey the coal produced in the coal mining face to the designated position; in the chemical industry, it can safely and reliably convey various chemical raw materials; and in the field of grain processing, it can efficiently complete the transfer task of grains.

[0004] Although the scraper conveyor has many advantages, the lower edge of the scraper is increasingly worn out during long-term use. This is because the lower edge of the scraper directly contacts the bottom of the trough and bears the friction force of the material during conveying, resulting in severe wear of this part. As the use time increases, the lower edge of the scraper gradually wears and shortens, which not only affects the smooth conveying of the material and reduces the conveying efficiency. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a scraper for scraper, which can adaptively elongate according to the depth of wear during use and wear, ensuring that the material transportation is not affected and prolonging the period of repair and replacement of the scraper.

[0006] To solve the above technical problems, the utility model provides a scraper for scraper, a scraper body, a mounting hole is formed in the upper part of the scraper body, a sliding cavity with an open lower end is arranged in the scraper body, a sliding scraper capable of extending from the lower end is slidably connected in the sliding cavity, at least two vertical strip-shaped limiting through grooves are formed in the scraper body and communicate with the sliding cavity, a threaded connection shaft corresponding to each strip-shaped limiting through groove is arranged on the upper part of each side of the sliding scraper, and an internally threaded limiting sleeve slidably connected with the corresponding strip-shaped limiting through groove is threadedly connected with each threaded connection shaft.

[0007] Through adoption of the above technical scheme, in long-time use, the lower edge of the sliding scraper is worn by friction between the lower edge and the tank bottom and the material, and is gradually shortened, but under the action of gravity, the sliding scraper can be self-adaptively slid out, so that the lower edge is always in contact with the tank bottom, and the material transportation is ensured, in the sliding process of the sliding scraper, the inner thread limiting sliding sleeve also slides in the strip-shaped limiting through groove, and in the rotating process of the scraper body, due to the connection between the inner thread limiting sliding sleeve and the strip-shaped limiting through groove, the sliding scraper can be prevented from being thrown out of the sliding cavity.

[0008] The scraper body is further provided with a strip-shaped insertion groove which is communicated with the strip-shaped limiting through groove and has an open lower end at the lower end of each strip-shaped limiting through groove, the width of each strip-shaped insertion groove is smaller than the width of the corresponding strip-shaped limiting through groove, the outer diameter of each threaded connecting shaft is equal to the width of the corresponding strip-shaped insertion groove, and the outer diameter of each inner thread limiting sliding sleeve is equal to the width of the corresponding strip-shaped limiting through groove.

[0009] Through adoption of the above technical scheme, when it is necessary to replace and install the sliding scraper, the inner thread limiting sliding sleeve is only needed to be removed, the sliding scraper can be taken out of the sliding cavity, a new sliding scraper is replaced, and the replacement is completed by connecting the thread limiting sliding sleeve with the threaded connecting shaft after the threaded connecting shaft of the new sliding scraper is inserted into the strip-shaped limiting through groove through the strip-shaped insertion groove, so that the installation and replacement of the sliding scraper are facilitated.

[0010] The utility model further sets up that one end of each inner thread limiting sliding sleeve is provided with a knob sleeve which is not circular in cross section.

[0011] The utility model further sets up that the cross section of each knob sleeve is regular hexagon.

[0012] The utility model further sets up that the edges of the two sides of the scraper body are outwardly provided with reinforcing edges at the edges of each strip-shaped limiting through groove.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Firstly, when the scraper is worn in use, the lower edge of the sliding scraper is worn and shortened, but the sliding scraper can be self-adaptively extended under the action of gravity, so that the lower edge of the sliding scraper is always in contact with the tank bottom, the material transportation is ensured, and the period of maintenance and replacement of the scraper is prolonged.

[0015] Secondly, when the lower edge of the sliding scraper is worn and cannot be in contact with the tank bottom, the sliding scraper needs to be replaced, but the scraper body can be repeatedly used, and the cost of wear and replacement is further reduced. BRIEF DESCRIPTION OF DRAWINGS
