[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model.
[0018] It should be noted that: like reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0019] In the description of the utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the utility model.
[0020] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0021] The following will Figures 1-4 specifically and in detail describe the structure and working process of the present utility model.
[0022] As Figures 1-4 shown, a counterattack liner for a counterattack crusher that strengthens the splitting effect includes a counterattack liner installed on the counterattack bracket of the crusher. The counterattack liner includes a counterattack liner body. Installation holes 2 are provided on the counterattack liner body, and a number of chisel nail fixing screw holes 3 are provided on the counterattack liner body. The chisel nail 4 is provided with an internal thread hole, and a bolt 5 passes through the chisel nail fixing screw hole and the internal thread hole on the chisel nail 4 to fix the chisel nail on the counterattack liner body. When the front part of the chisel nail is partially worn and the plate hammer on the rotor of the counterattack crusher is worn, by replacing the crushing chisel nail installed on the counterattack liner, the distance between the plate hammers on the rotor of the counterattack crusher is supplemented, and the impact force of the material counterattacked by the plate hammer on the chisel nail is increased, thereby improving the crushing effect of the counterattack crusher.
[0023] As Figure 3 shown, for the counterattack liner of the counterattack crusher that strengthens the splitting effect in the present utility model, the chisel nail is a conical chisel nail. The conical chisel nail is fixed to the counterattack liner body from the back to exert the splitting effect of the chisel nail on the material, quickly splitting the material hitting it, thereby improving the crushing effect of the heavy hammer crusher. The chisel nail is designed in a conical shape, so that the large pieces of material hitting it will quickly crack and break under the splitting effect of the chisel nail.
[0024] For the counterattack liner of the counterattack crusher that strengthens the splitting effect in the present utility model, the chisel nail fixing screw hole is a sunken hole, which is convenient for fixing the chisel nail on the back of the counterattack liner. There is no prominent display on the back of the counterattack liner, which is convenient for installing the counterattack liner body on the counterattack bracket of the crusher.
[0025] For the counterattack liner of the counterattack crusher that strengthens the splitting effect in the present utility model, the installation hole is a square bucket-shaped bolt hole, which is convenient for installing the bucket-shaped bolt 7 on the counterattack bracket of the crusher. The bucket-shaped bolt sinks to the bottom of the chisel nail on the counterattack liner body to prevent the head of the bolt from being worn.
[0026] For the counterattack liner of the counterattack crusher that strengthens the splitting effect in the present utility model, as Figure 4As shown in the figure, a first impact liner 1 and a second impact liner 6 are installed downward from the feeding end in the impact chamber. The installation density of the chiseling nails on the impact liner body of the first impact liner is less than that of the chiseling nails on the impact liner body of the second impact liner. The density of the chiseling nails arranged on the impact liner body varies according to the different positions of the impact liner in the crushing chamber. Generally, the density is higher on the impact liner installed on the impact panel in the second impact chamber, and the density is lower on the impact liner installed on the impact panel in the first impact chamber. Because the impact force of the material impact on the first impact chamber is small and the crushing effect is poor, a lower density arrangement can save production costs.
[0027] The density of the chiseling nails arranged on the impact liner can also be adjusted according to the difference in the fragility of the materials crushed by the crusher. Generally, for materials with good fragility, the density of the crushing chiseling nails is arranged lower, and for materials with poor fragility, the density of the crushing chiseling nails is arranged higher.
[0028] The utility model adopts the above-mentioned adjustable crushing chiseling nail structure design with enhanced splitting effect, which greatly improves the ability of the impact crusher to crush materials. At the same time, it is convenient and fast to replace the chiseling nails. By timely replacing the crushing chiseling nails, the gap between the plate hammer on the rotor and the impact chiseling nails can be adjusted, so that the impact crusher can maintain the best crushing effect for a long time, thereby improving the crushing ability of the impact crusher, reducing production costs, and increasing the economic benefits of the enterprise.
[0029] The above is only the preferred embodiment of the utility model. It should be pointed out that for those skilled in the art, without departing from the overall concept of the utility model, several changes and improvements can still be made, and these should also be regarded as the protection scope of the utility model.
