Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cone crushers, and specifically to a protective balance ring for a cone crusher. Background Technology
[0002] Multi-cylinder cone crushers are widely used, advanced equipment, and have high output. They can crush ores with high hardness and are widely used in industries such as mining, mineral processing, building materials, and highway and railway construction. Currently, a common problem with multi-cylinder cone crushers on the market is that the outer ring of the balance ring is worn down by falling stones, disrupting the balance and causing significant vibration. The balance ring also needs to be replaced approximately every six months, resulting in substantial maintenance costs.
[0003] The search revealed a patent publication number CN202762469U, entitled "A Protective Balance Ring Material," which specifically discloses a protective balance ring for a cone crusher. It includes a balance ring fixed on an eccentric sleeve, a protective ring that provides protection, and a protective layer that can be welded onto the outer edge of the protective ring. The protective ring and the balance ring are positioned by a stop and secured with bolts, which are located within the raised flange of the protective ring, effectively preventing accidental wear of the bolts.
[0004] Analysis of the publicly available materials above shows that the balance ring can be protected, but the replacement of vulnerable parts is inconvenient. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0024] like Figures 1-4 As shown: Example
[0025] A protective balance ring for a cone crusher includes a balance ring 6, a side guard plate 7 disposed on the outside of the balance ring 6, a cover plate 9 disposed on the upper end face of the balance ring 6, and a connecting belt 8 disposed between the side guard plate 7 and the cover plate 9; the side guard plate 7 and the cover plate 9 are arranged perpendicularly to each other.
[0026] In this embodiment, the balance ring 6 is installed inside the crusher body, i.e., the casing 1. The function of the balance ring 6 is to maintain the balance of the crusher during operation and prevent vibration. The balance ring 6 is sleeved on the main shaft 2. To prevent damage to the balance ring 6, a side guard plate 7 is installed on the outside of the balance ring 6. To facilitate the replacement of the side guard plate 7, the side guard plate 7 is connected to the cover plate 9 by a connecting strap 8. The side guard plate 7 can be replaced by removing the cover plate 9. In this technology, the cover plate 9 and the side guard plate 7 are designed to be perpendicular, which facilitates installation and disassembly and provides more comprehensive protection for the balance ring 6. Example
[0027] The side guard plate 7 is a ring structure, horizontally arranged, used to protect the outer end face of the balance ring 6.
[0028] Unlike the above embodiments, in this embodiment, the side guard plate 7 is designed to be annular and horizontally positioned, and its diameter is larger than that of the balance ring 6, making it easy to replace. Example
[0029] The cover plate 9 is provided with fixing bolts, and the balance ring 6 is connected to the fixing bolts.
[0030] Unlike the above embodiments, in this embodiment, in order to fix the cover plate 9, a countersunk hole is provided on the cover plate 9 and a fixing bolt is installed, which can effectively protect the fixing bolt, and the fixing bolt can also facilitate the replacement of vulnerable parts. Example
[0031] The balance ring 6 is equipped with a counterweight 5.
[0032] Unlike the above embodiments, in this embodiment, a counterweight 5 is added inside the balance ring 6 in order to enable the crusher to work. Example
[0033] The inner side of the balance ring 6 is connected to the main shaft 2 via the body and rotates under the action of the main shaft 2. The main shaft 2 is also connected to the crushing head 3.
[0034] Unlike the above embodiments, in this embodiment, there is a channel between the crushing head 3 and the shell, through which the crushed stones enter the outer side of the side guard plate 7 from the inlet at the lower end.
[0035] The working method (or working principle) of this utility model:
[0036] When this technology is in operation, it is applied to a cone crusher. The balance ring 6 is connected to the main shaft 2 and rotates under the action of the main shaft 2. Since the feed inlet 4 is above the edge of the balance ring 6, stones can easily damage the balance ring 6. Therefore, in order to protect the balance ring 6, a cover plate 9 is set on the upper end face of the balance ring 6 and fixed with fixing bolts. Then, the side guard plate 7 is connected by a connecting strip 8. The connecting strip 8 is a welded strip, and the side guard plate 7 and the cover plate 9 are set to a vertical relationship, which makes it easier to replace the vulnerable parts, the cover plate 9 and the side guard plate 7.
[0037] In this utility model, unless otherwise explicitly specified and limited, for example, it can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components or an interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
