Description

Technical Field

[0001] The utility model relates to the technical field of cone crushers, in particular to a counterweight protection device for cone crushers. Background Art

[0002] Cone crusher is a kind of crushing equipment widely used in many fields such as mining, smelting, building materials, highway, railway, water conservancy and chemical industry. It is mainly used for medium and fine crushing of various ores and rocks. The counterweight device of cone crusher is an important component for balancing and stabilizing the operation of crusher.

[0003] The existing counterweight device is generally composed of a counterweight body and a counterweight shield. However, during use, the crushed ore will hit the surface of the counterweight shield. After the counterweight shield is hit for a long time, the surface of the counterweight shield will be dented.

[0004] Therefore, in order to solve the above problems, a counterweight protection device for a cone crusher is provided. Utility Model Content

[0005] The purpose of the utility model is to provide a counterweight protection device for a cone crusher to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a counterweight protection device for a cone crusher, comprising a counterweight body, a counterweight shield being installed on the outer surface of the counterweight body, a protection component being arranged on the outer surface of the counterweight shield, the protection component comprising an outer shell, a protection ring being arranged on the lower surface of the outer shell, a first connecting plate being arranged on the inner surface of the outer shell, a connecting block being arranged on the inner surface of the protecting ring, the connecting blocks being set to four and evenly distributed, one end of the first connecting plate passing through two of the connecting blocks and extending downward, an installation groove being arranged on the outer surface of the first connecting plate, a sliding groove being arranged on the inner surface of the sliding groove, a spring being installed on the inner surface of the sliding groove, a slide plate being installed on the other end of the spring, a limiting ring being installed on the inner surface of the installing groove, a limiting block being installed on one end of the slide plate, a limiting hole being arranged on the outer surface of one of the connecting blocks, and a limiting block being installed in cooperation with the inner surface of the limiting hole.

[0008] Furthermore, a second connecting plate is provided on the inner surface of the shell, and one end of the second connecting plate passes through the other two connecting blocks and extends downward.

[0009] Furthermore, a limiting groove is provided on the inner surface of the slide groove, and a sliding block is provided on the outer surface of the slide plate, and the sliding block is slidably connected inside the limiting groove.

[0010] Furthermore, one end of the limit block is provided with an inclined surface.

[0011] The utility model has the following beneficial effects:

[0012] (1) The utility model can protect the counterweight shield by providing a protective ring, thereby preventing the crushed ore from hitting the surface of the counterweight shield during use, thereby achieving a better protective effect.

[0013] When the outer surface of the limit block is flush with the outer surface of the first connecting plate, the protective ring can be pulled downward to separate the end portion of the first connecting plate from one of the connecting blocks. When the end portion of the first connecting plate is completely separated from one of the connecting blocks, the spring restores its elasticity and pushes the slide plate to reset, so that the limit block is extended outward. When the upper surface of the limit block abuts against the lower surface of the other connecting block, the limit block is squeezed inward to push the slide plate, so that the slide plate moves into the slide groove. The spring gradually contracts. When the outer surface of the limit block is flush with the outer surface of the first connecting plate, the protective ring can be pulled downward to separate the protective ring from the outer shell, thereby facilitating the replacement of the protective ring and achieving a better practical effect.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
