Description

Technical Field

[0001] This utility model belongs to the field of mining machinery technology, specifically relating to a feeding device for a cone crusher. Background Technology

[0002] A cone crusher is a type of crushing machinery suitable for raw materials in the metallurgical, construction, road building, chemical, and silicate industries. Depending on the crushing principle and the desired particle size, it is available in many models. Crushers are widely used in mining, metallurgy, building materials, highways, railways, water conservancy, and chemical industries. Cone crushers offer a large crushing ratio, high efficiency, low energy consumption, and uniform product particle size, making them suitable for medium and fine crushing of various ores and rocks.

[0003] Patent CN206535643U discloses a uniform material distribution device for a cone crusher and the cone crusher thereof. The uniform material distribution device includes a support, a material distribution disc, a motor, a reducer, and a pulley transmission system. The material distribution disc has an opening at the top and a discharge port radially formed on its side. The material distribution disc is rotatably connected to the support, so that the opening at the top of the material distribution disc communicates with the top surface of the support. The motor and reducer are mounted on the frame, and the motor is driven by the input end of the reducer. The output end of the reducer is driven by the material distribution disc via a pulley transmission system. The pulley transmission system includes a driving pulley, a driven pulley, and a transmission belt. The driving pulley is driven by the output end of the reducer, and the driven pulley is driven by the material distribution disc. A transmission belt is wound between the driving pulley and the driven pulley. This invention can automatically perform uniform material distribution.

[0004] In the above scheme, the stone is rotated from the discharge port and scattered in all directions by the rotation of the feeding disc to achieve the effect of uniform distribution of stone. However, there are differences in particle size in the stone. Large stone particles often stay on the upper layer, while small stone particles accumulate on the lower layer. This problem causes the crusher to operate unstablely for a long time, which greatly shortens the service life of the crusher's parts. At the same time, the finished product produced by the crusher is also very unsatisfactory. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems by providing a cone crusher feeding device that can solve the technical issues described above.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cone crusher feeding device includes a drive shaft and a bearing housing. The drive shaft, driven by a hydraulic motor, horizontally passes through the bearing housing and forms an inner transmission section with both ends rotatably connected to the bearing housing. A feeding turntable is rotatably mounted vertically on the bearing housing. A driven shaft inserted into the bearing housing is located at the center of the feeding turntable. The inner transmission section and the driven shaft are linked through a transmission gear assembly.

[0008] In the cone crusher feeding device, both ends of the inner transmission section are provided with transverse bearings arranged circumferentially. The transverse bearings are respectively snapped onto the two opposite side walls of the bearing housing. One end of the inner transmission section is axially connected to the outer transmission section, which is located outside the bearing housing, and the transmission shaft.

[0009] In the cone crusher feeding device, the other end of the outer drive section relative to the inner drive section is connected to the hydraulic motor via a coupling.

[0010] In the cone crusher feeding device, the transmission gear assembly includes a transverse bevel gear and a longitudinal bevel gear that mesh with each other. The longitudinal bevel gear is disposed on the driven shaft, and the transverse bevel gear is disposed on the inner transmission section.

[0011] In the cone crusher feeding device, the transverse bevel gear and the longitudinal bevel gear are in perpendicular contact with each other, and the longitudinal bevel gear is located on the side of the inner transmission section near the hydraulic motor.

[0012] In the cone crusher feeding device, the bearing housing is provided with a driven through hole in the longitudinal direction, and the driven shaft passes through the driven through hole into the bearing housing and is rotatably connected to the inner wall of the driven through hole through a longitudinal bearing.

[0013] In the cone crusher feeding device, several annular stepped structures are provided on the inner wall of the driven through hole, and longitudinal bearings of different diameters are embedded in the corresponding stepped structures.

[0014] In the cone crusher feeding device, the feeding turntable is provided with feeding blades that extend radially from the center, and the feeding blades evenly divide the feeding turntable into several parts.

[0016] In the cone crusher feeding device, a ring-shaped protective barrier is provided around the feeding turntable, the hydraulic motor is installed on the outer wall of the protective barrier, and the drive shaft passes through the protective barrier from the inside and is connected to the hydraulic motor.

[0017] The advantages of this utility model are:

[0018] The inner transmission section of the drive shaft passes through the bearing housing, forming two rotational support points with the bearing housing, which increases the running stability of the drive shaft, thereby improving the transmission efficiency between the drive shaft and the driven shaft, as well as the meshing force at the meshing point, making the rotation of the fabric turntable more uniform and stable.

[0020] Figure 2 This is a schematic diagram of the internal structure of the bearing housing of this utility model.

[0021] Figure 3 This is a schematic diagram of the fabric blade structure of this utility model.

[0022] In the diagram, there are: drive shaft 1, inner drive section 11, transverse bearing 12, outer drive section 13, bearing housing 2, driven through hole 21, cloth turntable 3, cloth blade 31, driven shaft 4, longitudinal bearing 41, drive gear assembly 5, transverse bevel gear 51, longitudinal bevel gear 52, coupling 6, hydraulic motor 7, and protective enclosure 8. Detailed Implementation

[0023] The following are specific embodiments of the utility model, which are described in conjunction with the accompanying drawings to further illustrate the technical solution of the utility model. However, the utility model is not limited to these embodiments.

[0024] like Figures 1-3 As shown, the cone crusher feeding device includes a drive shaft 1 and a bearing housing 2. The drive shaft 1, driven by a hydraulic motor 7, horizontally passes through the bearing housing 2 and forms an inner transmission section 11 with both ends rotatably connected to the bearing housing 2. A feeding turntable 3 is rotatably arranged in the vertical direction of the bearing housing 2. A driven shaft 4 inserted into the bearing housing 2 is arranged at the center of the feeding turntable 3. The inner transmission section 11 and the driven shaft 4 are linked through a transmission gear assembly 5.

[0025] That is, the inner transmission section of the drive shaft passes through the bearing housing, forming two rotational support points with the bearing housing, which increases the running stability of the drive shaft, thereby improving the transmission efficiency between the drive shaft and the driven shaft and the meshing force at the meshing point, making the rotation of the fabric turntable more uniform and stable.

[0026] In this embodiment, both ends of the inner transmission section 11 are provided with transverse bearings 12 arranged in the circumferential direction. The transverse bearings 12 are respectively snapped onto the two opposite side walls of the bearing housing 2. One end of the inner transmission section 11 is axially connected to the outer transmission section 13 of the transmission shaft 1 located outside the bearing housing 2.

[0027] The transverse bearing 12 is a double-row tapered roller bearing. Its outer ring is fixed in the side wall hole of the bearing housing 2 by interference fit, and its inner ring is fixed to the shoulder of the inner transmission section 11 by lock nut to ensure the axial positioning and radial load-bearing capacity of the transmission shaft 1.

[0028] In this embodiment, the other end of the outer transmission section 13 relative to the inner transmission section 11 is connected to the hydraulic motor 7 via a coupling 6.

[0029] The hydraulic motor 7 is an axial piston type hydraulic motor, which is connected to the outer transmission section 6 via a coupling 7. The hydraulic motor 7 drives the outer transmission section 13 to rotate, and transmits power to the transmission gear assembly 5 through the inner transmission section 13. The coupling 6 is a flexible perforated coupling, which can compensate for minor coaxiality deviations between the transmission shaft 1 and the output shaft of the hydraulic motor 7, and reduce vibration.

[0030] In this embodiment, the transmission gear assembly 5 includes a transverse bevel gear 51 and a longitudinal bevel gear 52 that mesh with each other. The longitudinal bevel gear 52 is disposed on the driven shaft 4, and the transverse bevel gear 51 is disposed on the inner transmission section 11.

[0031] The transverse bevel gear 51 and the longitudinal bevel gear 52 are in perpendicular contact with each other, and the longitudinal bevel gear 52 is located on the side of the inner transmission section 11 near the hydraulic motor.

[0032] The transverse bevel gear 51 is fixed to the end of the inner transmission section 11, and its axis coincides with the transmission shaft 1. The longitudinal bevel gear 52 is fixed to the lower end of the driven shaft 4, and its axis is perpendicular to the transmission shaft 1.

[0033] The inner transmission section 11, which serves as the power input, is supported at both ends by transverse bearings 12. When the transverse bevel gear 51 on it is subjected to longitudinal pressure, it has the support stability to prevent the entire transmission shaft 1 from deviating from the axis position, thereby ensuring stable transmission contact between the transverse bevel gear 51 and the longitudinal bevel gear 52.

[0034] In this embodiment, a driven through hole 21 is provided longitudinally on the bearing housing 2. The driven shaft 4 passes through the driven through hole 21 into the bearing housing 2 and is rotatably connected to the inner wall of the driven through hole 21 through a longitudinal bearing 41.

[0035] Several annular stepped structures are provided on the inner wall of the driven through hole 21, and longitudinal bearings 41 of different diameters are embedded in the corresponding stepped structures.

[0036] Driven shaft 4 is rotatably connected to driven through hole 21 of bearing housing 2 via longitudinal bearing 41. The inner wall of driven through hole 21 is machined with three progressively smaller annular stepped structures from top to bottom. Deep groove ball bearings and thrust bearings are installed on the first and third steps respectively to withstand the radial and axial forces of driven shaft 4.

[0037] In this embodiment, the fabric turntable 3 is provided with fabric blades 31 extending radially from the center, and the fabric blades 31 evenly divide the fabric turntable 3 into several parts.

[0038] A central column is provided at the center of the feeding turntable 3, and the feeding blades 31 extend to the edge of the feeding turntable 3 through the side wall of the central column. When the feeding turntable 3 rotates, the material is pushed to rotate by the material-facing surface of the feeding blades 31, and is thrown out from the edge of the feeding turntable 3 under the action of centrifugal force.

[0039] This includes stones of various sizes. Small stones tend to converge downwards along the gaps between larger stones, resulting in uneven sizes between the upper and lower layers of the pile. Under centrifugal force, larger stones are thrown out of the feeding turntable 3 earlier, placing more large stones in the lower layer of the pile, thus balancing the positions of stones of different sizes in the pile.

[0040] Preferably, the fabric blades 31 are arranged in an arc shape opposite to the rotation direction of the fabric turntable 3.

[0041] That is, the material-facing surface of the cloth blade 31 is convex arc-shaped, so that the stone can gradually move towards the edge of the cloth turntable 3 along the material-facing surface, and avoid the material-facing surface of the cloth blade 31 from catching the stone and hindering the normal falling of the material when rotating.

[0042] In this embodiment, a ring-shaped protective barrier 8 is provided around the fabric turntable 3, and the hydraulic motor 7 is located on the outer wall of the protective barrier 8. The transmission shaft 1 passes through the protective barrier 8 from the inside and is connected to the hydraulic motor 7.

[0043] The protective barrier 8 is a ring-shaped steel plate structure welded and fixed around the fabric turntable 3. The hydraulic motor 7 is fixed to the outside of the protective barrier 8 by a bracket. The drive shaft 1 passes through the through hole at the protective barrier 8. A rubber sealing ring is installed in the through hole to prevent material splashing and damage to the hydraulic motor 7.

[0044] A material drop gap is left between the inner wall of the protective enclosure 8 and the edge of the cloth turntable 3. The material falls into the center of the cloth turntable 3 from the feed port and is evenly thrown outward along the arc surface of the cloth blade 31 under the action of centrifugal force, covering the entire working surface of the crushing chamber.

[0045] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
