Description

Technical Field

[0001] The utility model relates to a sprocket chip chain conveying anti-embedding technology, in particular to a slag embedding anti-structure of a sprocket for sewage discharge. Background Art

[0002] In addition to general transmission of rotation and ordinary chain network conveying, sprockets are also used to convey chips and other solid debris that come into direct contact, such as machining chips or chips. These debris will be squeezed by the chain and embedded in the surface of the sprocket groove. The more they are pressed, the harder they become, lifting the chain rollers, and in serious cases, the chain will break. This kind of fault is a hidden accumulation process, not easy to find, and once found, it is more troublesome to remove. Utility Model Content

[0003] The utility model aims to provide a slag embedding prevention structure for a sewage discharge sprocket to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A slag embedding prevention structure for a sprocket for sewage discharge comprises a wheel disc, a plurality of groups of equally spaced gear teeth are fixedly connected to the outer wall of the wheel disc, arc grooves are arranged between the gear teeth, and slag discharge grooves are arranged on both sides of the arc grooves.

[0006] As a further solution of the utility model: a mounting cylinder is fixedly connected to the middle position of the wheel disc.

[0007] As a further solution of the utility model: a positioning hole is provided in the installation cylinder.

[0008] As a further solution of the utility model: a keyway is provided on the inner wall of the installation cylinder.

[0009] Compared with the prior art, the beneficial effects of the utility model are: the design adopts a structure in which the chain sprocket automatically extrude debris to avoid jamming, which effectively avoids the continuous accumulation of grinding chips or cutting chips and improves the practicality of the product.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-2 In an embodiment of the utility model, a slag-proof embedding structure of a sprocket for sewage discharge includes a wheel disc, and a plurality of groups of equally spaced gear teeth are fixedly connected to the outer wall of the wheel disc, arc grooves are arranged between the gear teeth, and slag discharge grooves are arranged on both sides of the arc grooves. The utility model connects the chain through the gear teeth. When debris enters during the operation of the sprocket, the chain stick presses against the sprocket to squeeze the debris out of the part and slide out from both sides of the sprocket.

[0015] In one case of this embodiment, see Figure 1-2 A mounting tube is fixedly connected at the middle position of the wheel disc, a positioning hole is arranged in the mounting tube, and a key groove is arranged on the inner wall of the mounting tube. The utility model installs and fixes the wheel disc and the axle by setting the mounting tube, and axially limits the wheel disc and the axle by the mutual cooperation of the key groove and the key, and relatively fixes and limits the wheel disc and the axle by setting the positioning hole, thereby preventing relative sliding between the wheel disc and the axle.

[0016] The working principle of the utility model is as follows: the utility model installs and fixes the wheel disc and the axle by setting the installation cylinder, and axially limits the wheel disc and the axle by the mutual cooperation of the keyway and the key, and relatively fixes and limits the wheel disc and the axle by setting the positioning hole, so as to prevent relative sliding between the wheel disc and the axle, and connects the chain through the gear teeth. When foreign matter enters during the operation of the sprocket, the chain stick and the sprocket are pressed against each other to squeeze the foreign matter out of the part and slide out from both sides of the sprocket.

[0017] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0018] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
