Description

Technical Field

[0001] This utility model relates to the field of industrial equipment technology, specifically to a shared structure for different eccentric distances of the eccentric sleeve of a single-cylinder hydraulic cone crusher. Background Technology

[0002] Single-cylinder hydraulic cone crushers are core crushing equipment in mining, metallurgy, and building materials industries. Due to their simple structure, convenient maintenance, and low operating costs, they are widely used in the processing of medium and fine crushing of hard materials. Their core component, the eccentric sleeve, transmits crushing power and drives the moving cone to oscillate, directly determining the equipment's crushing performance (such as crushing force, discharge port size, and production capacity).

[0003] The eccentric sleeve design of traditional single-cylinder hydraulic cone crushers has significant limitations: the eccentricity is fixed and non-adjustable. Different material characteristics (such as hardness and particle size) and production requirements (such as output and finished particle size) necessitate varying oscillation amplitudes in the crushing chamber. For example, processing high-hardness rocks requires increasing the eccentricity to enhance crushing force, while soft materials or fine crushing require decreasing the eccentricity to avoid over-crushing. Because the eccentricity of traditional equipment is non-adjustable, it is difficult to meet diverse production needs with a single structure, necessitating replacement of the entire machine or redesign of components, resulting in resource waste. Therefore, we propose a single-cylinder hydraulic cone crusher with a shared eccentric sleeve structure for different eccentricities to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A single-cylinder hydraulic cone crusher with a shared structure for eccentric sleeves with different eccentricities includes:

[0006] The sleeve is cylindrical and has an internal shaft hole. The center line of the shaft hole does not coincide with the center line of the sleeve. The outer wall of one end of the sleeve has notches at equal intervals near the shaft hole. The other side of the outer wall of the sleeve has a connecting hole at the position corresponding to the notch.

[0007] A conical crusher has a connecting cylinder fixedly installed at its bottom. The connecting cylinder is slidably sleeved on the outer surface of the sleeve. The center line of the conical crusher does not coincide with the center line of the sleeve. A retaining strip is fixedly installed on the upper side of the inner wall of the connecting cylinder. The retaining strip is adapted to the notch. A first screw is threadedly connected to the outer wall of the other side of the connecting cylinder. The first screw is threadedly connected to the connecting hole.

[0008] Furthermore, the number of the strip-shaped notches is 3 to 5.

[0009] Furthermore, both the card strip and the notch are in the shape of an isosceles trapezoid.

[0010] Furthermore, there are two connecting holes and two first screws.

[0011] Furthermore, the outer port of the connecting hole is conical.

[0012] Furthermore, the bottom of the connecting cylinder is connected to a second screw via an annular array thread, and an annular groove is provided on the bottom side of the outer wall of the sleeve.

[0013] Furthermore, the annular array inside the annular groove is fixed with anti-slip strips.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention features multiple sets of equally spaced notches on the outer wall of the sleeve. By embedding the clamping strip into different notches, the equipment can achieve different eccentricities and thus different crushing strokes. By adjusting the eccentricity, the swing amplitude of the moving cone can be directly controlled, optimizing the pressure distribution in the crushing chamber, reducing over-crushing rate, and improving the uniformity of finished product particle size and production capacity. At the same time, the device has low maintenance costs, requiring no replacement of the eccentric sleeve or transmission system. Only the position of the clamping strip needs to be adjusted to adapt to changes in working conditions. The same equipment can flexibly match different materials and production needs, reducing resource waste caused by replacing equipment or components. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] This application provides a shared structure for eccentric sleeves with different eccentricities in a single-cylinder hydraulic cone crusher. It primarily addresses the problem that existing traditional equipment, due to its non-adjustable eccentricity, cannot meet diverse production needs with a single structure, requiring replacement of the entire machine or redesign of components, resulting in resource waste. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0023] A single-cylinder hydraulic cone crusher with a shared structure for eccentric sleeves with different eccentricities includes:

[0024] The sleeve 1 is columnar. The internal structure of the sleeve 1 has a shaft hole 101. The center line of the shaft hole 101 does not coincide with the center line of the sleeve 1. The outer wall of one end of the sleeve 1 has notches at equal intervals on the side near the shaft hole 101. The other side of the outer wall of the sleeve 1 has a connecting hole 103 at the position corresponding to the strip notch 102.

[0025] The cone crusher 2 has a connecting cylinder 3 fixedly installed at its bottom. The connecting cylinder 3 is slidably sleeved on the outer surface of the sleeve 1. The center line of the cone crusher 2 does not coincide with the center line of the sleeve 1. A retaining strip 4 is fixedly installed on the upper side of the inner wall of the connecting cylinder 3. The retaining strip 4 is adapted to the notch. A first screw 5 is threadedly connected to the outer wall of the other side of the connecting cylinder 3. The first screw 5 is threadedly connected to the connecting hole 103.

[0026] Workflow Description:

[0027] The sleeve 1 (including shaft hole 101) is fixed on the drive shaft of the single-cylinder hydraulic cone crusher. According to the material characteristics or production requirements, a preset eccentricity is selected, and the connecting cylinder 3 is sleeved on the upper end of the sleeve 1, so that the retaining strip 4 on the inner wall of the connecting cylinder 3 is embedded in a notch on the outer wall of the sleeve 1. The first screw 5 is tightened through the connecting hole 103 to fix the relative position of the sleeve 1 and the connecting cylinder 3. When the crushing operation is performed, the drive shaft drives the sleeve 1 to rotate. The sleeve 1 drives the connecting cylinder 3 and the cone crusher 2 to swing synchronously through the eccentricity, and the moving cone generates a crushing stroke with a set amplitude.

[0028] Eccentricity adjustment procedure:

[0029] First, loosen the first screw 5 to release the locking state of the retaining strip 4 and the notch, switch the notch corresponding to the retaining strip 4 (different notches correspond to different eccentricities), and put the connecting cylinder 3 on the upper end of the sleeve 1. Then, screw the first screw 5 back into the corresponding connecting hole 103, press the retaining strip 4 and the notch together, and complete the eccentricity adjustment.

[0030] The single-cylinder hydraulic cone crusher features a shared structure with different eccentricities in its eccentric sleeve. By setting multiple sets of equally spaced notches on the outer wall of the sleeve body 1, and embedding the clamping strip 4 into different notches, the equipment can obtain different eccentricities and different crushing strokes. By adjusting the eccentricity, the swing amplitude of the moving cone can be directly controlled, optimizing the pressure distribution in the crushing chamber, reducing the over-crushing rate, and improving the uniformity of the finished product particle size and production capacity. At the same time, the equipment has low maintenance costs, requiring no replacement of the eccentric sleeve or transmission system. Only the position of the clamping strip 4 needs to be adjusted to adapt to changes in working conditions. The same equipment can flexibly match different materials and production needs, reducing resource waste caused by replacing equipment or parts.

[0031] like Figure 4 As shown, in some embodiments, the number of strip notches 102 is 3 to 5. More specifically, 3 to 5 notches can provide 3 to 5 levels of eccentricity adjustment options to meet the needs of different material hardness, particle size and production targets. If the number of notches is too large (such as more than 5), the groove density on the outer wall of the sleeve 1 will be too large, which will significantly weaken the structural strength of the sleeve 1 and lead to the risk of fatigue fracture under long-term load.

[0032] like Figure 3 As shown, in some embodiments, both the locking strip 4 and the notch are isosceles trapezoids. More specifically, the symmetrical design of the isosceles trapezoid provides an automatic alignment mechanism for the engagement of the locking strip 4 and the notch. During assembly, after the inclined surface of the locking strip 4 contacts the inclined surface of the notch, it can be quickly aligned by slight adjustments (such as rotation or translation) without the need for precise calibration. At the same time, the inclined surface design on both sides of the isosceles trapezoid can significantly enhance the engagement stability of the locking strip 4 and the notch. When the locking strip 4 is embedded in the notch, the contact of the inclined surfaces will form a wedge-shaped self-locking effect.

[0033] like Figure 3 As shown, in some embodiments, there are two connecting holes 103 and two first screws 5. More specifically, the engagement of the locking strip 4 with the notch forms rapid positioning, while the engagement of the two screws with the connecting holes 103 forms a mechanical interlock. Even if the equipment vibrates strongly, the slippage of the locking strip 4 can be effectively suppressed.

[0034] like Figure 4 As shown, in some embodiments, the outer port of the connecting hole 103 is conical. More specifically, the geometric characteristics of the conical surface enable it to have an automatic alignment function. When the first screw 5 (usually a cylindrical threaded rod) approaches the connecting hole 103, the conical surface restricts the axial and radial degrees of freedom of the first screw 5. The conical surface forces the screw axis to coincide with the axis of the connecting hole 103, avoiding thread misalignment caused by tilting. The gradually contracting shape of the conical surface provides a guiding path for the screw, ensuring that the thread is smoothly screwed into the inner hole and reducing the difficulty of manual alignment.

[0035] like Figure 3As shown, in some embodiments, the bottom of the connecting cylinder 3 is connected to a second screw 6 in an annular array threaded connection, and an annular groove 104 is provided on the bottom side of the outer wall of the sleeve 1. More specifically, the second screw 6 is distributed in an annular array at the bottom of the connecting cylinder 3, usually 3-6 evenly arranged (adjusted according to the size of the equipment). It is screwed into the annular groove 104 on the bottom side of the outer wall of the sleeve 1 by threading. Its core function is to fix the connecting cylinder 3 axially on the sleeve 1, prevent it from moving up and down due to equipment vibration or inertial force, and ensure that the mating position of the clamping strip 4 and the notch remains stable during operation.

[0036] like Figure 4 As shown, in some embodiments, the annular array inside the annular groove 104 is fixed with anti-slip strips. More specifically, the second screw 6 provides the main fixing force to axially press the connecting cylinder 3, while the anti-slip strips serve as auxiliary constraints to prevent the screw from loosening due to vibration.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
