In order to achieve the purpose, the utility model provides the following technical scheme:
a protection device applied to a head nut on a Shantevick CH870 crusher comprises a protection device body;
the protection device body comprises an outer diameter of
The protection plate, the protection plate periphery is provided with four archs, the center of protection plate has been seted up the internal diameter and has been
The inner bore of (a).
Preferably, the protrusions are arranged two by two symmetrically.
Preferably, the thickness of the protective plate is 20 mm;
the height of the protrusion is 50mm, the width is 100mm, and the thickness is 20 mm.
Compared with the prior art, the utility model has the following beneficial effects:
1. the protection device for the head nut applied to the Shantevick CH870 crusher provided by the utility model has the advantages of simple manufacture, convenience in use, low cost, high reliability and the like, and is suitable for being popularized to other CH series crushers.
2. According to the protection device for the head nut applied to the Shantevick CH870 crusher, after the head nut protection device is added, the service life of the nut of the crusher head is prolonged to about 12 months from 3 months of original fine crushing and 2 months of original intermediate crushing. Therefore, the cost is saved by more than 130 ten thousand every year after the utility model is implemented, and the cost of the spare parts of an enterprise is greatly reduced.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top/bottom", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "sleeved/connected," "connected," and the like are to be construed broadly, e.g., "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The reason why the head nut 3 is worn is as follows:
since the CH870 crusher is an upper feeding device, the head nut is mainly subjected to impact abrasion, so that the protection device for the head nut 3 is added, and the abrasion problem of the head nut 3 can be effectively solved.
To solve the problem of wear of the head nut 3, the outer diameter is set to
The center of the protection plate 61 is provided with an inner diameter of
The hole 62 to set up four arch 63 on protection plate 61, and with on its welding to first nut 3, the ore has directly fallen on protection plate 61 like this, has avoided the impact of ore to first nut 3, has reduced the wearing and tearing of first nut 3, has prolonged the life of first nut 3.
As shown in fig. 1, which shows a specific structural schematic diagram of the present invention, the present invention provides a protection device for a head nut applied to a hartvick CH870 crusher, comprising a protection device body 6;
the protective device body 6 comprises an outer diameter of
The protection plate 61, the periphery of the protection plate 61 is provided with four protrusions 63, the center of the protection plate 61 is provided with an inner diameter of
The inner bore 62.
In the present invention, the protrusions 63 are symmetrically arranged two by two.
In the present invention, the thickness of the shielding plate 61 is 20 mm;
the height of the protrusion 63 is 50mm, the width is 100mm, and the thickness is 20 mm.
As shown in fig. 2, showing the application of the utility model to a mountain vicker CH870 crusher, the protection device body 6 is welded to the head nut 3; the main shaft 2 penetrates through the inner hole 62 and then is rotatably connected with the upper arm support cap 1;
when the crusher operates, the ore 7 enters the cavity of the crusher, and the ore 7 is extruded and crushed through the relative motion of the fixed cone lining plate 4 and the movable cone lining plate 5. The protection device body 6 is arranged on the head nut 3, so that the impact of the ore 7 on the head nut 3 is effectively reduced;
the four protrusions 63 on the outer edge of the protector body 6 facilitate the removal and installation of the head nut 3. When the lining plate is replaced by the disassembling machine, the protection device body 6 can be disassembled, the protection device body 6 which is newly manufactured can be replaced, and the protection device body 6 is simple to manufacture and extremely low in cost.
The service life of the head nut 3 of the protection device body 6 provided by the utility model is prolonged from 3 months to 12 months, the effect is obvious, and the head nut can be popularized to other CH series crushers.
