[0002] Cone crushers are widely used in material crushing industries such as mining and building materials, and they play an indispensable role in the crushing system. For example, in the traditional crushing section of the building materials industry, after the jaw crusher performs coarse crushing, the crushed stone enters the cone crusher for fine crushing, and the finely crushed stone enters the impact crusher for shaping or sand making. There are also multiple auxiliary machines including vibrating screens, feeders, conveyors, etc. In this crushing system, the output of cone crushing directly determines the size of this production line, and all the main crushing machines and auxiliary machines are serving the cone crusher.

[0003] In the building materials industry, with the increase in the amount of natural sand collected and the growing demand for sand, the content of natural sand in the natural environment is getting lower and lower, and excessive collection of natural sand has caused great damage to the natural environment. Therefore, it is an irreversible trend for machine-made sand to replace natural sand. In this case, sand and gravel suppliers have to pay a higher price to produce more machine-made sand. As in the above example, in the crushing system of jaw crusher-cone crusher-impact crusher, a fourth crushing stage will be added, jaw crusher-cone crusher-impact crusher-high pressure roller mill (impact crusher), so as to produce more machine-made sand.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0049] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use, or the positions or positional relationships commonly understood by those skilled in the art, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0050] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0052] like Figures 1 to 6 As shown, a cone crusher of this embodiment includes a casing 1; the casing 1 is covered on the upper frame assembly, thereby separating the outside world from the space inside the casing 1, which on the one hand increases the beauty of the appearance, and on the other hand reduces the erosion of impurities and increases the service life.

[0053] The upper frame assembly is movably arranged on the casing 1; the upper frame assembly swings under the drive of the power assembly, thereby moving relative to the lower frame assembly to crush materials.

[0054] The lower frame assembly is located in the casing 1 and is movably connected to the upper frame assembly; the lower frame assembly is movably connected to the upper frame assembly, so that the upper frame assembly drives the lower frame assembly to swing, and the relative movement of the two increases the crushing force, thereby improving the quality and efficiency of the crushed materials.

[0055] The power assembly is connected to the upper frame assembly to drive the upper frame assembly to swing; the power assembly provides a power source for the cone crusher and effectively ensures the progress of the crushing work.

[0056] The process of crushing materials is explained in conjunction with the structure of the cone crusher, wherein a crushing chamber for crushing materials is formed between the upper frame assembly and the lower frame assembly, and the swinging motion of the upper frame assembly acts on the materials and is transmitted to the lower frame assembly, so that the lower frame assembly is forced to swing.

[0057] The material enters the cone crusher from the upper frame assembly, that is, the crushing chamber. The upper frame assembly is driven by the power assembly to swing, thereby changing the inner diameter of the crushing chamber, thereby crushing the material. Under the action of the crushing force, the material is crushed and the size of the material is reduced. In addition, the crushing force is transmitted through the material to the lower frame assembly. Since the lower frame assembly is movably connected to the upper frame assembly, the lower frame assembly is forced to swing. At the moment of crushing the material, the movement of the upper frame assembly is opposite to the movement of the lower frame assembly, thereby increasing the absolute value of the crushing force and helping to improve the quality and effect of crushing.

[0058] The cone crusher drives the lower frame assembly to swing under pressure through the upper frame assembly, so that the upper frame assembly and the lower frame assembly move toward each other during the crushing process, thereby increasing the absolute value of the crushing force and helping to improve the quality and effect of crushing.

[0059] The laminated crushing is realized to the maximum extent; the non-directional crushing trajectory makes it easier to find the defects of the material during the material crushing process, and use the defects as the crushing opening for crushing, so that a larger crushing ratio can be achieved with the least crushing energy.

[0060] Compared with the existing cone crusher, it has the characteristics of larger crushing ratio, energy saving, load start-up, etc. For example, in the above building material crushing system, it can be replaced by a jaw crusher - this cone crusher, and the two-stage crushing can achieve the original three-stage or four-stage crushing effect.

[0061] In the mining industry, the finer the material, the higher the sorting efficiency. Its production system is divided into crushing, grinding and sorting. Grinding provides raw materials for sorting, and crushing provides raw materials for grinding. However, in the grinding stage, the grinding efficiency is relatively low, and it is necessary to provide larger power, larger equipment, more infrastructure and personnel to grind out materials that meet the requirements of sorting. The concept of "more crushing and less grinding" was proposed under this condition. If the material is crushed as small as possible in the crushing stage, it is possible to reduce more investment in the grinding stage. The use of this cone crusher can maximize the realization of "more crushing and less grinding", thereby saving energy and reducing crushing costs.

[0062] Optionally, the cone crusher is described using the mining industry as an example, but its application scope is not limited to the mining industry. It can also be used in material crushing operations in building materials, cement or other suitable industries, and the present invention does not impose any limitation on this.

[0063] In the specific implementation of the present invention, as an option, the upper frame assembly includes: an upper frame 21, connected to the housing 1; the upper frame 21 is connected to the housing 1 on the one hand, and is used for installing other components on the other hand. Preferably, the upper frame 21 can be constructed as any suitable structure to adapt to different construction environments, and the present invention does not impose any limitation on this.

[0064] The mortar wall 22 is placed on the upper frame 21; the mortar wall 22 is fixedly connected to the upper frame 21, and a plurality of step surfaces are provided on the inner wall surface of the mortar wall 22, thereby helping to improve the crushing effect.

[0065] Optionally, the mortar wall 22 can be made of high manganese steel, high-quality high manganese steel, modified high manganese steel, new high manganese steel, ultra-high manganese steel, ultra-strong high manganese steel, modified high manganese steel or other suitable materials, and the present invention does not impose any limitation on this.

[0066] At least two vibrators 23 are fixed on the upper frame 21 and are evenly distributed on the periphery of the mortar wall 22 with the mortar wall 22 as the center. The vibrators 23 act as vibration machines to vibrate the upper frame 21 and the mortar wall 22 connected to the upper frame 21, thereby changing the inner diameter of the crushing chamber to achieve crushing of the material.

[0067] Optionally, the number of the vibrators 23 can be reasonably selected according to the size of the upper frame 21, the crushing requirements, the model of the vibrator 23 and other conditions, which will not be elaborated here.

[0068] Now, in combination with the structure of the upper frame assembly, the operation of the upper frame assembly during the crushing process is described, wherein, driven by the power assembly, the vibrator 23 generates an excitation force, thereby causing the upper frame 21 and the mortar wall 22 to vibrate, and the distance between the inner wall surface of the mortar wall 22 and the lower frame assembly changes, that is, the inner diameter of the crushing chamber changes, and the mortar wall 22 applies a crushing force to the material, thereby causing the mortar wall 22 to cooperate with the lower frame assembly to extrude and crush the material.

[0069] In a possible design, the upper frame 21 includes a frame body divided into several layers and several connecting rods connecting adjacent frames, wherein a mounting plate 5 is provided on the lower side of the lowest frame body, and the frame body is connected to the mounting plate 5 through an elastic member 6; to supplement the structure of the upper frame 21, in view of the height of the mortar wall 22 and the lower frame assembly, the frame body needs to be provided with multiple layers. The mounting plate 5 is used to fix the cone crusher in the working position or connect it to other equipment. At the same time, in order to prevent the vibration of the cone crusher during crushing from affecting the stability of the connection, an elastic member 6 is provided between the mounting plate 5 and the frame body, and the elastic member 6 absorbs impact and vibration, thereby reducing the vibration of the mounting plate 5.

[0070] Optionally, the structure of each layer of the frame can be the same or different, which is selected according to actual usage, and the structure of the frame can also be constructed as any suitable structure, and the present invention does not impose any limitation on this.

[0071] Optionally, the mounting plate 5 is constructed as any suitable structure, and the present invention does not impose any limitation on this.

[0072] Optionally, the elastic member 6 is a shock-absorbing spring or other suitable spring or elastomeric material; it is easy to understand that those skilled in the art can select the required number of elastic members 6 according to actual use, which will not be described in detail here.

[0073] Correspondingly, the housing 1 is covered on the adjacent frames. For the housing 1, the housing 1 is composed of a plurality of shell plates, which cover the adjacent frames. For example, the gap between the upper and lower frames is covered by a vertically arranged shell plate, and the upper end surface of the uppermost frame is covered with a horizontally arranged shell plate, which will not be described in detail here.

[0074] In the specific implementation manner provided by the present invention, as an option, the power assembly includes at least two motors 41, and the motors 41 are arranged one by one corresponding to the vibrator 23; the motors 41 drive the vibrator 23 to rotate, thereby causing the upper frame assembly to vibrate.

[0075] Optionally, the motor 41 is configured as any suitable type of motor, and the present invention does not impose any limitation on this.

[0076] Furthermore, the power assembly also includes a synchronous belt 42, which connects adjacent motors 41 to make the motors 41 rotate synchronously. In theory, the motors 41 and the exciters 23 arranged one by one can achieve synchronous rotation, but due to manufacturing errors, there will be a speed difference during operation, resulting in an increasingly large cumulative phase difference, causing a change in the crushing force, so the use of the synchronous belt 42 can effectively control this asynchronous situation.

[0077] In the specific embodiment provided by the present invention, as an option, the lower frame assembly includes: a lower frame 31, which is movably connected to the upper frame 21 and is located below the mortar wall 22; the lower frame 31 is connected to the upper frame 21, and at the same time provides an installation position for the piston assembly 32 and the movable cone assembly 33.

[0078] Optionally, the lower frame 31 is constructed into any suitable structure according to usage conditions, and the present invention does not impose any limitation on this.

[0079] The piston assembly 32 is fixed on the lower frame 31; on the one hand, the piston assembly 32 provides a placement surface for the movable cone assembly 33, and on the other hand, the piston assembly 32 is connected to the piston cylinder 10, so that the movable cone assembly 33 slides up and down to adjust the inner diameter of the crushing chamber, thereby facilitating material discharge, avoiding blockage, balancing the crushing force, and helping to increase the service life.

[0080] The lower end of the movable cone assembly 33 is placed on the piston assembly 32, and the upper end passes through the lower frame 31 and is inserted into the mortar wall 22, so that a crushing chamber is formed between the movable cone assembly 33 and the mortar wall 22. The movable cone assembly 33 and the mortar wall 22 form a crushing chamber to complete the crushing of the material.

[0081] Now, in combination with the structure of the lower frame assembly, the operation of the lower frame assembly during the crushing process is described, wherein the material is subjected to the crushing force from the mortar wall 22, and the crusher squeezes and crushes the material while transmitting the force through the material to the movable cone assembly 33, and then to the lower frame 31 and the piston assembly 32. Since the lower frame 31 is movably connected to the upper frame 21, the lower frame assembly is forced to swing under the influence of the crushing force. At the moment of crushing the material, the movement of the upper frame assembly and the movement of the lower frame assembly are opposite, thereby increasing the absolute value of the crushing force, which helps to improve the quality and effect of crushing.

[0082] In a possible design, the piston assembly 32 includes a piston cylinder 321 and a piston body 322 slidably disposed in the piston cylinder 321, wherein the upper end of the piston cylinder 321 is fixedly connected to the lower frame 31, the lower end of the piston cylinder 321 is connected to the piston cylinder 10, and a sealed cavity connected to the piston cylinder 10 is formed below the piston body 322.

[0083] The piston body 322 slides up and down in the driving piston cylinder 321 of the piston cylinder 10, and the movable cone assembly 33 abutting against the piston body 322 slides up and down with the piston body 322, thereby adjusting the distance between the movable cone assembly 33 and the mortar wall 22, that is, the inner diameter of the crushing chamber.

[0084] Optionally, the upper end of the piston cylinder 321 is provided with a ring portion for connecting to the lower frame 31, and is connected to the lower frame 31 by bolt connection, flange connection or other suitable connection methods, which will not be described in detail here.

[0085] In a possible design, the piston cylinder 10 includes an oil cylinder connected to the sealing chamber and a pump body connected to the oil cylinder. The pump body drives the hydraulic medium in the oil cylinder to flow into the sealing chamber, so that the piston body 322 slides and pushes up the cone assembly 33.

[0086] The structure of the piston cylinder 10 is described, wherein the oil cylinder is connected to the sealed cavity, which is the portion of the piston tube 321 located below the piston body 322. The oil cylinder is filled with hydraulic medium, and the pump body is started to drive the hydraulic medium to flow from the oil cylinder into the sealed cavity, thereby sliding the piston body 322. Conversely, after the pump body stops working, the hydraulic medium and the piston body 322 return to the initial position under the action of gravity.

[0087] Optionally, the oil cylinder and the pump body may be of any suitable type, and the present invention does not impose any limitation on this.

[0088] In a possible design, the movable cone assembly 33 includes a main shaft 331 and a movable cone 332 sleeved on the main shaft 331, wherein the lower end of the main shaft 331 is slidably disposed in the piston cylinder 321 and abuts against the piston body 322, and the upper end of the main shaft 331 passes through the lower frame 31 and is inserted into the mortar wall 22, and the movable cone 332 is at least partially located in the mortar wall 22, thereby forming a crushing chamber with the mortar wall 22.

[0089] The structure of the movable cone assembly 33 is supplemented, wherein the main shaft 331 is the part that abuts against the piston body 322, and the cross section of the movable cone 332 is conical, and then cooperates with the mortar wall 22 to form a crushing chamber. When the piston body 322 slides up and down, the main shaft 331 moves with it. Preferably, in order to improve the sliding accuracy of the main shaft 331, a sleeve is provided on the lower frame 31, and the main shaft 331 is inserted into the sleeve.

[0090] In the specific embodiment provided by the present invention, as an option, Figure 2-3 As shown in Figures 6 and 7, the upper frame assembly is connected to the lower frame assembly through a suspension rod structure 9. The suspension rod structure 9 ensures that the lower frame assembly can be forced to swing, thereby increasing the absolute value of the crushing force. Specifically, the suspension rod structure 9 includes an upper fixing seat 91 fixed to the upper frame assembly; a lower fixing seat 92 fixed to the lower frame assembly; and a suspension rod 93, the upper end of which is hinged to the upper fixing seat 91 and the lower end of which is hinged to the lower fixing seat 92.

[0091] Optionally, the upper fixing seat 91 and the lower fixing seat 92 are respectively constructed as any suitable structure, and the present invention does not impose any limitation thereto. Preferably, the upper fixing seat 91 and the lower fixing seat 92 are constructed as the same structure, thereby saving economic costs.

[0092] The upper and lower ends of the suspension rod 93 are hinged, thereby retaining the degree of freedom of the suspension rod structure 9 to facilitate the forced swinging of the lower frame 31.

[0093] In the specific embodiment provided by the present invention, as an option, the cone crusher further includes a feed hopper 7 located above the upper frame assembly and a discharge hopper 8 located below the lower frame assembly, wherein the feed hopper 7 is connected to the upper frame assembly through the casing 1. The provision of the feed hopper 7 and the discharge hopper 8 ensures the entry and outflow of materials, prevents the materials from flowing around, and reduces the pollution of the surrounding environment during the crushing process.

[0094] In this cone crusher, the crushing force can be achieved by adjusting the degree of unbalanced eccentricity on the vibrator 23 or adjusting the rotation speed. For example, Figure 1-2As shown, the vibrators 23 are arranged in four groups and are divided into two groups with two diagonally opposite ones. The crushing force can be adjusted by adjusting the angle between any one group of eccentricities and the other group of eccentricities, that is, under the condition of the same rotation speed, when the two groups are in the same direction, the angle is regarded as 0°, and the crushing force is the largest; when the two groups of eccentricities are just opposite, the angle is regarded as 180°, and the crushing force is the smallest; the two groups of eccentricities can be adjusted at 0°-180° to achieve the adjustment of the crushing force.

[0095] Regarding adjusting the rotation speed, that is, the size of the crushing force is proportional to the square of the angular velocity, the rotation speed can significantly change the size of the crushing force. Specifically, the motor 41 is configured as a variable frequency motor, thereby realizing stepless speed regulation of the variable frequency motor through the frequency converter. The higher the rotation speed, the greater the crushing force; the lower the rotation speed, the opposite is true.

[0096] Furthermore, by adjusting the combination of the above two variables, the purpose of adjustment under conditions such as different materials, different feed particle sizes and different required particle sizes can be achieved, thereby expanding the scope of use and also helping to increase the market competitiveness of the cone crusher.

[0097] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0098] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
