Abstract

The invention discloses a movable cone lining plate of a cone crusher with adjustable throughput and crushing ratio, which comprises a movable cone lining plate body, wherein a plurality of claw-shaped grooves are formed in the movable cone lining plate body, the claw-shaped grooves are grooves lower than the outer surface of the movable cone lining plate cone, the trend of the claw-shaped grooves is from top to bottom, the size of the claw-shaped grooves is from wide to narrow, a horizontal boss is arranged at the upper half part of the movable cone lining plate body, and the claw-shaped grooves are formed in the horizontal boss part. The particles slide down to the crushing cavity along with the grooves, so that friction and viscosity between the materials and the lining plate are overcome, the materials fall down more easily and are squeezed into the crushing cavity more quickly, and lamination crushing is facilitated.

Description

Dynamic cone lining plate of cone crusher with adjustable throughput and crushing ratio Technical Field The invention relates to the technical field of cone crushers, in particular to a movable cone lining plate of a cone crusher with adjustable throughput and crushing ratio. Background The cone crusher is a very wide mechanical device applied in the mining machinery field, and can crush materials so as to obtain materials with required granularity, and is provided with a hollow inverted conical outer shell, wherein an inverted conical hollow fixed cone lining plate is lined in the shell, the outer shell does not move, a conical movable cone is arranged in the outer shell, a movable cone lining plate is arranged on the surface of the movable cone, and the movable cone eccentrically swings. In operation, when the movable cone swings, the gap between the movable cone and the external shell forms a crushing cavity, the gap of the crushing cavity periodically changes in size, materials in the gap are extruded when the gap is reduced, and the materials fall when the gap is increased. The movable cone lining plate is an important component of the cone crusher and is a key component for realizing material crushing. However, the traditional cone crusher has the defects of insufficient crushing efficiency of materials, uneven material granularity and larger deviation of material size and particle shape. When large-particle materials enter, the traditional cone crusher can only passively increase the pressure of the dynamic cone lining plate and the fixed cone lining plate to crush large particles, so that the pressure of the crusher is overlarge, overload is easy to occur, and even equipment is damaged. The crushing cavity of the cone crusher is in an inverted cone shape, which requires uniform distribution when materials fall into the crushing cavity, and the dynamic and fixed cones are balanced in stress, and if the materials enter unevenly or the granularity of the materials is separated, the large and small particle materials are respectively deviated to one side, the unbalanced stress can also occur. Therefore, developing a motor cone lining plate of a cone crusher with reasonable structure becomes a key for improving the crushing efficiency of the cone crusher on materials, improving the particle shape, increasing the throughput and improving the stress. During the operation of the cone crusher, various dynamic cone lining plate structures have a great influence on the crushing efficiency of the cone crusher, thereby influencing the performance of the cone crusher. The dynamic cone lining board of the cone crusher is not only required to bear the chiseling abrasion of the high impact force of the materials, but also required to bear the ploughing and scouring abrasion of the high stress of the materials, so that the high manganese steel with high toughness and high wear resistance is selected as the dynamic cone lining board material, and the requirements of the dynamic cone lining board of the cone crusher can be well met. However, the traditional dynamic cone lining plate structure of the cone crusher has the characteristics of low crushing efficiency of the cone crusher on materials, deviation of the sizes and the grain shapes of the materials and the like, so that the reasonable design of the dynamic cone lining plate structure is particularly important for improving the performance of the dynamic cone lining plate, and theoretical guidance and technical support are provided for improving the performance of the cone crusher. In the prior art, the upper half part of the conical outer surface of the cone liner plate of the cone crusher is provided with a boss in the horizontal circumferential direction, so that the large-sized materials are crushed more easily at the upper part of the crushing cavity. The upper half part of the conical outer surface of the movable cone lining plate is provided with a longitudinal groove, so that the lining plate entity is reduced, and the cost is reduced. Both of the above structures do not solve the problems set forth above. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a movable cone lining plate of a cone crusher with adjustable throughput and crushing ratio, which aims to design an adjustable horizontal boss at the upper half part of the movable cone lining plate, so as to prevent large-particle materials from entering a crushing cavity, and cause overlarge pressure of the crushing cavity and overload phenomenon. The change of the boss causes the ratio of the capacity and the crushing ratio of the cone crusher to be changed accordingly. Meanwhile, a plurality of claw-shaped grooves with the concave angles of minus 10 degrees to plus 30 degrees are designed at the boss part, the boss and the grooves jointly realize the function of controlling the material flow speed of materials, the materials can uniformly and controllably enter t
