Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical structures, and in particular relates to an inertial cone crusher. Background Art

[0002] Inertia cone crusher is a commonly used crushing equipment, widely used in mining, smelting, building materials and other industries. The body of the inertia cone crusher is mounted on the base frame through vibration isolation elements. The working mechanism consists of a fixed cone and a moving cone, and the space between the cones forms a crushing chamber. The main shaft of the moving cone is inserted into the sleeve, and the exciter on the sleeve; the rotational motion of the motor is transmitted to the exciter through the transmission mechanism. When the exciter rotates, it generates inertial force, forcing the moving cone to do a pendulum motion around the center of the spherical bushing of the machine base. In a vertical plane, when the moving cone approaches the fixed cone, the material is impacted and squeezed and crushed. When the moving cone leaves the fixed cone, the crushed product is discharged from the discharge port due to its own weight.

[0003] The sliding friction pair is formed between the vibrator and the main shaft through the shaft sleeve, which can be understood as a sliding bearing. The friction between the sliding friction pair will generate a lot of heat. At the same time, a lot of heat will be generated in the crushing process and transferred to the transmission mechanism through the sliding friction pair. The sliding friction pair has a large contact area and a large heat conduction area, which causes serious heating of the system, affecting normal work and increasing maintenance costs.

Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0013] Figure 1 This is a schematic structural diagram of an inertial cone crusher provided in an embodiment of the utility model. DETAILED DESCRIPTION

[0014] The following is a clear and complete description of the technical solutions in the embodiments of the utility model in conjunction with the drawings 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. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0015] First, the terms that may be used in this article are explained as follows:

[0016] The term “and / or” means that either or both of them can be realized at the same time. For example, X and / or Y means both “X” or “Y” and “X and Y”.

[0017] The terms "include", "comprises", "contains", "has" or other descriptions with similar semantics should be interpreted as non-exclusive inclusion. For example, including certain technical feature elements (such as raw materials, components, ingredients, carriers, dosage forms, materials, dimensions, parts, components, mechanisms, devices, steps, procedures, methods, reaction conditions, processing conditions, parameters, algorithms, signals, data, products or products, etc.) should be interpreted as including not only certain technical feature elements explicitly listed, but also other technical feature elements known in the art that are not explicitly listed.

[0018] The term "consisting of..." means excluding any technical feature elements not explicitly listed. If this term is used in a claim, it will make the claim closed, so that it does not contain technical feature elements other than the technical feature elements explicitly listed, except for the conventional impurities related to them. If this term only appears in a clause of a claim, it only limits the elements explicitly listed in the clause, and the elements recorded in other clauses are not excluded from the overall claim.

[0019] The term "parts by mass" refers to the mass ratio relationship between multiple components. For example, if it is described that component X is x parts by mass and component Y is y parts by mass, then the mass ratio of component X to component Y is x:y. 1 part by mass can represent any mass, for example, 1 part by mass can be represented as 1 kg or 3.1415926 kg. The sum of the parts by mass of all components is not necessarily 100 parts, but can be greater than 100 parts, less than 100 parts or equal to 100 parts. Unless otherwise specified, the parts, proportions and percentages described herein are all measured by mass.

[0020] Unless otherwise specified or limited, the terms "installed", "connected", "connected", "fixed" and the like 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 an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this article can be understood according to specific circumstances.

[0021] When concentration, temperature, pressure, size or other parameters are expressed in the form of a numerical range, the numerical range should be understood to specifically disclose all ranges formed by the pairing of any upper limit, lower limit, and preferred value in the numerical range, regardless of whether the range is explicitly stated; for example, if a numerical range of "2 to 8" is stated, the numerical range should be interpreted as including ranges such as "2 to 7", "2 to 6", "5 to 7", "3 to 4 and 6 to 7", "3 to 5 and 7", "2 and 5 to 7", etc. Unless otherwise specified, the numerical ranges stated herein include both their end values ​​and all integers and fractions within the numerical range.

[0022] The orientation or position relationship indicated by terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc. are based on the orientation or position relationship shown in the drawings and are only for the convenience and simplification of description, and do not explicitly or implicitly indicate 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 understood as a limitation of this document.

[0023] The embodiments of the utility model will be described in further detail below in conjunction with the accompanying drawings.

[0024] like Figure 1 As shown, an inertial cone crusher comprises a casing 1, a fixed cone 2, a main shaft 3, a moving cone 4, an exciter 5 and a rolling bearing 6. The casing 1 is mounted on the ground or a base frame, and can be mounted on the ground or the base frame through a vibration isolation element. The fixed cone 2 is mounted on the casing 1, and is fixedly connected by bolts.

[0025] The moving cone 4 is mounted on the casing 1 through a spherical pair; specifically, a concave spherical surface is provided at the center of the upper side of the casing 1, and a convex spherical surface is provided below the moving cone 4, and the two spherical surfaces cooperate to form a spherical pair.

[0026] The movable cone 4 is fixedly mounted on the upper part of the main shaft 3, and the vibrator 5 is mounted on the lower part through a rolling bearing 6. The vibrator 5 is driven by a motor and a transmission mechanism, which are not shown in the figure. The motor is connected through the transmission mechanism and drives the vibrator 5 to rotate and drive the movable cone 4 to perform a rotary pendulum motion along the spherical surface pair, and cooperate with the fixed cone 2 to complete the crushing work. The transmission mechanism usually uses a horizontal transmission shaft to drive the vibrator 5 through a bevel gear.

[0027] The vibrator 5 generally adopts an eccentric block. When the eccentric block rotates, it generates inertial force, forcing the moving cone 4 to do a pendulum motion around the center of the spherical pair. In a vertical plane, when the moving cone 4 approaches the fixed cone 2, the material is impacted and squeezed and crushed. When the moving cone 4 leaves the fixed cone 2, the crushed product is discharged from the discharge port due to its own weight.

[0028] At the same time, an inner lining plate 7 is installed inside the fixed cone 2. An outer lining plate 8 is installed outside the moving cone 4. The inner lining plate 7 and the outer lining plate 8 can be made of high hardness materials and can be replaced if excessively worn.

[0029] In this example, the vibrator 5 is installed by using a rolling bearing 6. The rolling friction generates less heat, the rolling friction pair has a small contact area, and the heat conduction area is small, which greatly reduces the heating of the system and saves the cost of maintenance.

[0030] The rolling bearing 6 works in rolling friction, while the sliding bearing works mainly in sliding friction. Sliding friction has high requirements on the lubrication system, and the target equipment, the inertia cone crusher, often works in a relatively harsh working environment. In this case, deep groove ball rolling bearings or spherical roller bearings with relatively low requirements on the working environment can meet the use requirements.

[0031] Working principle: Figure 1 As shown, when working, the motor drives the vibrator 5 to rotate through the transmission mechanism to generate inertial centrifugal force, which is transmitted to the main shaft 3 through the rolling bearing 6, thereby driving the moving cone 4 to move relative to the fixed cone 2. Since the fixed cone 2 and the moving cone 4 are both installed on the casing 1, the fixed cone 2 is fixed relative to the casing 1, and the moving cone 4 can rotate and swing relative to the vertical center axis of the casing 1. Therefore, when the crushing chamber between the moving cone 4 and the fixed cone 2 is filled with materials, the movement of the moving cone 4 relative to the fixed cone 2 can generate a force on the materials, causing them to be crushed. The rolling bearing designed between the vibrator 5 and the main shaft 3 of the utility model rolling bearing inertial cone crusher reduces the heat generated by the relative movement between the vibrator and the main shaft during operation.

[0032] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
