Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyors, in particular to a combined sprocket for a scraper conveyor. Background Art

[0002] The working principle of a scraper conveyor is that an open chute serves as a bearing member for coal, gangue, or materials, etc., and scrapers are fixed on a chain (forming a scraper chain) as a traction member. When the head drive part is started, the sprocket on the head shaft rotates, causing the scraper chain to circulate and move the material along the chute until it is unloaded at the head. The scraper chain bypasses the sprocket to make a stepless closed-loop operation to complete the transportation of the material.

[0003] Currently, the sprockets used in scraper conveyors are integrally fixed and installed on the outer wall of the drive shaft. During the long-term operation of the scraper conveyor, due to the wear of the material and the chain, the wear of the sprocket teeth is uneven, and even some sprocket teeth are prone to breakage. Usually, only the whole sprocket can be replaced, with a high usage cost and complex operation. Content of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3, A combined sprocket for a scraper conveyor, comprising: a fixed seat 1, an installation pipe 2, a fixing plate 3, a plug rod 4, a semi-gear disk 5, a tooth groove 6, a connecting plate 7, a nut 8 and a bolt 9. It further includes: An installation pipe 2 is fixedly connected inside the fixed seat 1, which is convenient for connecting the fixed seat 1 with the driving shaft of the scraper conveyor. At the same time, a fixing plate 3 is fixedly connected to the surface of the fixed seat 1, which is convenient for connecting the tooth cover assembly at the front and rear ends of the fixed seat 1 through the fixing plate 3. And tooth cover assemblies are connected to both the front and rear ends of the fixed seat 1, ensuring the stability and balance of the sprocket during operation. Specifically, each set of tooth cover assemblies arranged at the front and rear ends has semi-gear disks 5 arranged vertically, and a plurality of tooth grooves 6 are equidistantly arranged on the outer wall of the semi-gear disk 5. Through such a setting, the vertically arranged tooth cover assemblies are fixedly installed at the front and rear ends of the fixed seat 1, so that the tooth grooves 6 are sleeved and installed on the outer wall of the fixed seat 1, ensuring the rotation effect of the fixed seat 1 driving the tooth grooves 6 and realizing the stable operation of the sprocket;

[0021] Specifically, considering the stable connection of the tooth cover assemblies on both sides at the front and rear ends of the fixed seat 1, the fixing plate 3 is fixedly connected on both sides of the center of the fixed seat 1, and a semi-gear disk 5 is connected to the surface of the fixing plate 3 through a connecting plate 7. Among them, connecting plates 7 are attached to the upper and lower ends of the fixing plate 3, and the connecting plates 7 are fixedly connected to the outer wall of the semi-gear disk 5, and the connecting plates 7 and the fixing plate 3 are fixedly connected by bolts 9, ensuring the installation effect of the upper and lower semi-gear disks 5 on the surface of the fixed seat 1. At the same time, considering the installation firmness and positioning effect of the semi-gear disk 5 on the surface of the fixed seat 1, a plurality of plug rods 4 are fixedly connected to the surface of the fixed seat 1. When the semi-gear disk 5 is covered and installed on the surface of the fixed seat 1, the plug rods 4 penetrate and are inserted into the semi-gear disk 5. At the same time, insertion holes for accommodating the plug rods 4 to be inserted are correspondingly opened inside the semi-gear disk 5, ensuring the stability of the installation position of the semi-gear disk 5 on the surface of the fixed seat 1 and arranging the insertion holes in an annular and equidistant manner, ensuring the insertion stability of the plug rods 4 inside the semi-gear disk 5. At the same time, considering the installation firmness and stability of the two semi-gear disks 5 on the outer wall of the plug rods 4, nuts 8 are threadedly connected to the outer wall of the plug rods 4, and the nuts 8 are arranged on the surface of the semi-gear disk 5, realizing the locking and fixing of the semi-gear disk 5 by the nuts 8 externally and ensuring the stability and safety of the sprocket during operation.

[0022] Working principle: During use, the fixing seat 1 is installed on the outer wall of the driving shaft of the scraper conveyor through the installation pipe 2, which facilitates the driving shaft to drive the fixing seat 1 to rotate. By fixedly connecting the insertion rod 4 to the surface of the fixing seat 1, the upper and lower half gear disks 5 are fitted and installed on one side of the fixing seat 1 through the insertion rod 4, and the connecting plate 7 is fitted on the surface of the fixing plate 3. By connecting the insertion rod 4 to both the front and rear ends of the fixing seat 1, half gear disks 5 are installed at both the front and rear ends of the fixing seat 1. The nuts 8 are used to limit the insertion rod 4 at both ends, so that the nuts 8 are fitted and limited on the outer wall of the half gear disks 5, ensuring the closing and locking effects of the front and rear end tooth cover assemblies on both sides of the fixing seat 1. At the same time, by fitting the connecting plate 7 on the outer wall of the fixing plate 3, the bolt 9 is used to fix the connecting plate 7 and the fixing plate 3, realizing the firm connection of the upper and lower half gear disks 5. Through such a setting, the sprocket is realized in a four-way combination, and the structure is stable, ensuring the force-bearing effect during the rotation of the sprocket, and at the same time facilitating the later replacement and maintenance. In this way, the working principle of the combined sprocket is completed.
