DETAILED DESCRIPTION

[0029] 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.

[0031] Furthermore, the material of the first main body 1 of the liner is high manganese steel, and the material of the second main body 2 of the liner is high manganese steel, and high manganese steel has the characteristics of high strength and high toughness. The high-strength characteristic of high manganese steel means that high manganese steel can withstand greater pressure and load, is not easy to deform or break, and can maintain its stability and safety even after being impacted by stones for a long time; secondly, high manganese steel has good wear resistance, so that the liner can resist the wear and scratches given by stones, extending the service life of the liner; finally, high manganese steel has good high-temperature stability, can maintain its strength and stability at high temperatures, is not easy to deform or soften, and ensures that the liner can maintain its strength after being impacted by large stones under high temperature during long-term stone crushing.

[0032] Figure 2 The schematic diagram of the structure of the first main body of the middle lining plate of the utility model is shown. Figure 3 The cross-sectional view of the first main body of the liner in the utility model is shown. The front end of the first main body 1 of the liner is concave toward the rear end to form an arc-shaped upper crushing end. The upper crushing end is provided with a plurality of striking bosses 3. The top of the first main body 1 of the liner is provided with a plurality of first connecting grooves 11. The bottom of the first main body 1 of the liner is provided with a plurality of first positioning columns 12 and a plurality of first positioning holes 13. Preferably, the top of the first main body 1 of the liner is provided with two first connecting grooves 11, and the bottom of the first main body 1 of the liner is provided with two first positioning columns 12 and two first positioning holes 13. The first connecting groove 11 is used to connect with the positioning rib of the crushing chamber of the crusher, thereby fixing the position of the first main body 1 of the liner.

[0033] Furthermore, a first handle 14 is provided on the rear end face of the first liner body 1, and the first handle 14 is used to facilitate carrying the first liner body 1 to a desired place. A first positioning groove may also be provided on the first handle, and when the first liner body 1 is installed in the crusher, the operator cannot directly carry the first liner body 1 by hand, and can use a hook to hang on the handle and get stuck in the first positioning groove, so as to prevent the main board on the liner from colliding and rubbing with other objects during the carrying process, thereby increasing the service life of the first liner body 1.

[0034] Figure 4 The schematic diagram of the structure of the second main body of the middle lining plate of the utility model is shown. Figure 5The cross-sectional view of the second main body of the liner in the utility model is shown. The front end of the second main body 2 of the liner is concave toward the rear end to form a circular arc-shaped lower crushing end. The lower crushing end is provided with a plurality of striking bosses 3. The bottom of the second main body 2 of the liner is provided with a plurality of second connecting grooves 21. The top of the second main body 2 of the liner is provided with a plurality of second positioning columns 22 and a plurality of second positioning holes 23. Preferably, the second main body 2 of the liner is provided with two second connecting grooves 21, and the top of the lower main board of the liner is provided with two second positioning columns 22 and two positioning holes. The second connecting groove 21 is used to connect with the positioning rib of the crushing chamber of the crusher, thereby fixing the position of the second main body 2 of the liner.

[0035] Furthermore, a second handle 24 is provided on the rear end face of the second liner body 2, and the second handle 24 is used to facilitate carrying the second liner body 2 to a desired place. A second positioning groove may also be provided on the second handle. When the second liner body 2 is installed in the crusher, the operator cannot directly carry the second liner body 2 by hand, but can use a hook to hang on the handle and get stuck in the second positioning groove to prevent the lower main board of the liner from colliding and rubbing with other objects during transportation, thereby increasing the service life of the second liner body 2.

[0036] Furthermore, the striking boss 3 is triangular, arc-shaped or trapezoidal. The striking boss 3 can be selected in different shapes according to different situations. In the present embodiment, the striking boss 3 is preferably a triangular striking boss 3. The triangular striking boss 3 has relatively good stability, can withstand greater pressure and load, and the vertex of the triangle can concentrate the force in one place. When the stone collides with the triangular striking boss 3, the stone can be better broken into multiple pieces; the trapezoidal striking boss 3 has a larger support area, which can better disperse the pressure and load, so that the trapezoidal striking boss 3 can withstand the impact of heavier stones, and the vibration after the impact is relatively small; the arc-shaped striking boss 3 has excellent impact resistance, which can disperse the impact to the entire lining, thereby extending the service life of the lining.

[0037] Furthermore, during long-term use, a thick layer of stone fragments may remain on the surface of the triangular striking boss 3. When a stone hits the triangular striking boss 3, the stone will come into contact with the stone fragments remaining on the surface, causing a "stone hitting stone" phenomenon, thereby protecting the triangular surface and extending the service life of the triangular striking boss 3.

[0038] Furthermore, a frosted layer is provided at the bottom of the first liner body 1, and a frosted layer is provided at the top of the second liner body 2. The bottom of the first liner body 1 abuts against the top of the second liner body 2, and both the bottom of the first liner body 1 and the top of the second liner body 2 are provided with a frosted layer, which greatly improves the friction between the bottom of the first liner body 1 and the top of the second liner body 2, reduces the impact of the liner with stones, and causes the upper liner body and the lower liner body to separate, ensuring the efficiency of the crusher in crushing stones.

[0039] Figure 6 The cross-sectional schematic diagram of the wear-resistant and high-temperature-resistant crusher side lining is shown, and a shock-absorbing layer 4 is provided on the crushing end, and the shock-absorbing layer 4 is located between the striking boss 3 and the crushing end. The shock-absorbing layer 4 is used to absorb the vibration generated by the striking boss 3 after being hit by a stone, thereby reducing the vibration of the striking boss 3 on the crushing end. When the striking boss 3 is hit by a stone, it will vibrate, and the shock-absorbing layer 4 absorbs the vibration of the striking boss 3, thereby reducing the vibration of the striking boss 3 on the crushing end, thereby extending the service life of the liner.

[0040] Further, the first positioning column 12 is inserted into the second positioning hole 23, and the second positioning column 22 is inserted into the first positioning hole 13. The two first positioning columns 12 are located between the two first positioning holes 13, and the two second positioning holes 23 are located between the two second positioning columns 22. The position of the first positioning column 12 corresponds to the second positioning hole 23, and the position of the second positioning column 22 corresponds to the first positioning hole 13. When the lining plate is hit by a stone, the first positioning column 12 is inserted into the second positioning hole 23, and the second positioning column 22 is inserted into the first positioning hole 13, so that the first lining plate body 1 and the second lining plate body 2 are tightly connected, reducing the risk of the first lining plate body 1 and the second lining plate body 2 being separated, and ensuring the efficiency of the crusher in crushing stones.

[0041] Furthermore, the first lining body 1 is provided with a first connecting portion 15 and a first connecting trapezoidal groove 16, wherein the connecting portion is located on the left side wall of the first lining body 1, and the connecting trapezoidal groove is located on the right side wall of the first lining body 1; the second lining body 2 is provided with a second connecting portion 25 and a second connecting trapezoidal groove 26, wherein the connecting portion is located on the left side wall of the second lining body 2, and the connecting trapezoidal groove is located on the right side wall of the second lining body 2. The first connecting portion 15 is used to be inserted into the first connecting trapezoidal groove 16 of another first lining body 1, so that two first lining bodies 1 are connected. Based on this connection method, multiple first lining bodies 1 are connected to form a fixed circle of the first lining bodies 1. The fixed circle of the first lining body 1 is conducive to dispersing the force received by one of the first lining bodies 1 to other first lining bodies 1 after being hit by a stone, thereby extending the service life of the lining.

[0042] Similarly, the second connecting portion 25 is used to be inserted into the second connecting trapezoidal groove 26 of another lining second body 2, so that the two lining second bodies 2 are connected. Based on this connection method, multiple lining second bodies 2 are connected to form a lining second body 2 fixing circle. The lining second body 2 fixing circle is conducive to dispersing the force received by one of the lining second bodies 2 to other lining second bodies 2 after being hit by a stone, thereby extending the service life of the lining. And when the lining first body 1 is installed above the lining second body 2, the lining second body 2 disperses the force received to the lining first body 1 after being hit by a stone, further extending the service life of the lining.

[0043] Furthermore, the first connection part 15 is provided with a connection column 17, and the second connection part 25 is provided with a connection hole 27, and the connection column 17 is inserted into the connection hole 27. When the stone hits the liner for many times, the temperature of the liner will rise after being hit for many times, causing the shape of the connection column 17 to expand slightly, so that the connection between the connection column 17 and the connection hole 27 is more tightly connected, reducing the risk of the first liner body 1 and the second liner body 2 being separated, and ensuring the efficiency of the crusher in crushing stones.

[0044] The utility model also proposes a crusher, which includes the wear-resistant and high-temperature resistant crusher side lining, wherein the first main body of the wear-resistant and high-temperature resistant crusher side lining is inserted on the crusher body, or the second main body of the wear-resistant and high-temperature resistant crusher side lining is inserted on the crusher body.

[0045] Furthermore, the first liner body is inserted in the crusher, or the second liner body is inserted in the crusher, and the use positions of the first liner body 1 and the second liner body 2 can be interchanged, that is, after long-term use, all the second liner bodies 2 in the crusher are worn to a certain extent, and all the first liner bodies 1 in the crusher can be turned upside down as new second liner bodies 2, and the damaged second liner bodies 2 can be turned upside down as new first liner bodies 1.

[0046] In summary, the utility model provides a first lining body and a second lining body. When the second lining body is worn, the second lining body is replaced, thereby avoiding wasting half of the non-wear lining and reducing production costs. The first lining body and the second lining body have the same general appearance. When the second lining body is worn, the first lining body can be used as a new second lining body, thereby improving the utilization rate of the lining and reducing production costs.
