Description

Technical Field

[0001] The invention belongs to the technical field of crushing equipment, and in particular relates to a cone crusher and a method for obtaining a variety of product particle sizes. Background Art

[0002] Cone crushers are mainly used in non-ferrous metal mines, metallurgical industry, construction industry, cement industry, sand and gravel industry, etc. In nuclear power, highways, airports and mines, they play the role of medium and fine crushing, and even ultra-fine crushing. In recent years, due to changes in market conditions and the continuous needs of customers, both domestic users of crushers and equipment manufacturers have begun to be interested in and research various types of crushers. Gradually, different types of crushers have also begun to become the equipment models that the current crusher industry has begun to pay attention to. However, the cone crusher still uses the extrusion crushing principle. During the operation of the equipment, the material is squeezed against each other through the crushing cavity formed by the moving cone lining on the moving cone and the fixed cone lining on the fixed cone. During the operation of the equipment, the material to be crushed is clamped, thereby realizing a process from large size to small size of the material, and finally discharged from the discharge port.

[0003] The cone crusher transmits the external motive force to the large gear, counterweight, bushing and upper thrust bearing through the horizontal shaft and small gear, and rotates around the main shaft supported by the frame and the lower thrust bearing. During the internal movement of the cone crusher, the contact between the bushing and the collar controls the periodic rotation of the moving cone. During the movement of the moving cone, it needs to be supported by the spherical bearing, spherical bearing bushing and spherical bearing frame installed on the main shaft. The moving cone liner is fastened by the locking bolt to ensure the installation position, and the dividing cap on the upper part of the locking bolt extends the service life of the locking bolt. During the working process, the crushed material enters the crushing cavity between the moving cone liner and the fixed cone liner, thereby obtaining crushed products of different sizes. The cone crusher has the advantages of large crushing ratio, high output, low power consumption, uniform product particle size and suitable for crushing hard materials. The power transmission method of cone crusher mostly adopts pulley transmission power, and there is also a coupling to directly transmit power. The power of the motor is transmitted to the horizontal shaft through the pulley or coupling, so that the horizontal shaft drives the small gear, and the small gear meshes and rotates with the large gear, causing the eccentric sleeve to rotate, thereby prompting the main shaft to swing, and then driving the moving cone liner to keep the distance between it and the fixed cone liner in a tight and tense state, thereby crushing the incoming material.

[0004] Although cone crushers currently on the market can adjust the particle size of different material ranges by adjusting the size of the discharge port, the range of materials produced is relatively small. During the material inspection process, unreasonable material grading and serious over-diameter of material output often occur. It is impossible for a single crusher to simultaneously produce materials with a reasonable particle size range and particle grade interval. Summary of the invention

[0005] The object of the present invention is to provide a cone crusher and method capable of obtaining a variety of product particle sizes, so that materials with different particle sizes can be produced simultaneously on a single cone crusher.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a cone crusher that can obtain a variety of product particle sizes, characterized in that it includes a main shaft, a spherical support assembly, a frame, a horizontal shaft assembly, an eccentric assembly, a movable cone assembly and a fixed cone assembly, the main shaft is arranged in the frame, the eccentric assembly is sleeved on the main shaft, the movable cone assembly is seated on the main shaft through the spherical support assembly, the fixed cone assembly is arranged on the upper part of the movable cone assembly, and cooperates with the movable cone assembly to form a crushing chamber, the lower part of the movable cone assembly is sleeved on the eccentric assembly, the horizontal shaft assembly drives the eccentric assembly to rotate, and drives the movable cone assembly to swing in a circle; a detachable shaft ring is arranged at the lower part of the movable cone assembly, the shaft ring is sleeved on the eccentric assembly, the inner ring of the shaft ring and the outer ring of the eccentric assembly form a cooperative drive, and the inner ring of the shaft ring is formed by the intersection of several sections of inwardly recessed first circular arc contours of the same or different radii.

[0007] Furthermore, the eccentric assembly is an eccentric sleeve sleeved on the main shaft, and the outer ring of the eccentric sleeve is formed by the intersection of a plurality of inwardly protruding second arc contours with the same or different radii.

[0008] Furthermore, the intersection of two adjacent first arc contours has a smooth transition, and the intersection of two adjacent second arc contours has a smooth transition.

[0009] Furthermore, several segments of the first arc contours use the same center or different centers, and several segments of the second arc contours use the same center.

[0010] Furthermore, a gap is left between the inner ring of the moving cone assembly and the eccentric assembly, and they are installed in a non-rigid connection manner.

[0011] Furthermore, the maximum arc radius of the first arc profile is equal to the maximum arc radius of the second arc profile.

[0012] Furthermore, different weight counterweights are arranged at different positions inside the moving cone assembly. Different specifications and models of the shaft ring and the eccentric sleeve are selected, and the installation position of the counterweight in the height direction needs to be adjusted. When the counterweight is placed in different positions, according to F=m*a (F is force, m is mass, and a is acceleration), F is proportional to m, and M=F*L (M is torque, F is force, and L is the lever arm), M is proportional to L. When the distance from the suspension point perpendicular to the F direction is longer, the force applied can be smaller to obtain the same torque. On the contrary, the distance from the suspension point perpendicular to the F direction increases, F also increases, and the torque M obtained can be doubled. The principle of adjustment follows the properties and density of the material to be crushed and the crushing force required for the cohesion between the lattices in the crushed material to avoid over-crushing of the material. The counterweight is preferably fixed in the moving cone assembly by magnetic attraction or bolt fastening, which is convenient for fastening, installation and adjustment.

[0013] Furthermore, the shaft ring on the moving cone assembly and the eccentric sleeve on the eccentric assembly are always used in pairs, and are mainly adjusted according to different product particle size ranges and grading requirements. The selection method is mostly to match the same eccentric sleeve with different shaft rings. During operation, the maximum arc radius of the eccentric sleeve is equal to the maximum arc radius of the shaft ring, so as to ensure that the first arc contour of the inner ring of the shaft ring always has at least one point in contact with the second arc contour of the outer ring of the eccentric sleeve, so as to ensure that the eccentric distance is continuously changed and adjusted according to the pre-designed requirements.

[0014] Furthermore, the eccentric sleeve and the collar are designed to match multiple arcs. With the rotation in the circumferential direction, the second arc profile at the same position of the eccentric sleeve will contact the first arc profile of different segments of the collar alternately with the change of the rotation angle. Similarly, the first arc profile at the same position of the collar will contact the second arc profile of each position of the eccentric sleeve alternately with the change of the rotation angle. During the rotation of a full circle, the eccentricity is adjusted and changed many times, so the crushing ratio is also adjusted many times. Since the crushing ratio = incoming material particle size / discharged material particle size, when the particle size range of the incoming material particle size is constant, the difference in eccentricity changes the crushing ratio, which directly affects the difference in the discharge particle size. According to the collar and eccentric sleeve selected in advance, a better and more reasonable discharge particle size range and gradation can be obtained. The eccentric sleeve model specifications include: same arc radius with the same center, different arc radius with the same center; the collar model specifications include: same arc radius with the same center, different arc radius with the same center, different arc radius with the same center, different arc radius with different centers;

[0015] The selection principle should be followed: the same arc radius (eccentric sleeve) with the same center and different arc radius (shaft collar), different centers with the same arc radius (shaft collar), and different centers with different arc radius (shaft collar);

[0016] Concentric different arc radii (eccentric sleeve) and concentric same arc radius (shaft collar), concentric different arc radii (shaft collar), different centers with the same arc radius (shaft collar), different centers with different arc radii (shaft collar);

[0017] In the above-mentioned matching process between the eccentric sleeve and the collar: the maximum arc radius of the eccentric sleeve should be equal to the maximum arc radius of the collar. During the circular rotation, at least one arc is guaranteed to be in contact and matching state at every moment. The outer ring of the eccentric sleeve uses arc profiles of different radii, and requires smooth transitions at the intersections of arcs of different segments. The arc radius in different intervals can be designed as multiple segments with different arc radii to meet more gradation segments with continuous needs. However, the designed arc segments should not reduce the requirements of processing design too much. The arc profiles of the arc segments will be different if the size of the arc radius is different.

[0018] Furthermore, an inner hole is provided at the lower part of the frame, the lower part of the main shaft is inserted into the inner hole, a thrust bearing is provided on the main shaft between the eccentric sleeve and the inner hole, the thrust bearing includes an upper thrust bearing and a lower thrust bearing, the lower thrust bearing is seated on the frame, the upper thrust bearing is arranged on the lower thrust bearing, the eccentric sleeve is seated on the upper thrust bearing, a counterweight is provided on the upper sleeve of the eccentric assembly, and the eccentric assembly is pressed against the upper thrust bearing by the counterweight. (Counterweight equipment is available, which is used to lower the center of gravity of the equipment and reduce the amplitude of the equipment. The large gear, eccentric sleeve and counterweight are fixed together by bolts, the main shaft is fixed to the frame, and the rotation of the large gear drives the eccentric sleeve and counterweight to move together and rotate around the main shaft)

[0019] Furthermore, the spherical support assembly includes a spherical bearing, a spherical bearing bushing and a spherical bearing frame. The spherical bearing frame is installed on the top of the main shaft, the spherical bearing bushing is installed on the spherical bearing frame, and the spherical bearing is slidably arranged on the spherical bearing bushing.

[0020] Furthermore, the moving cone assembly includes a moving cone, a moving cone liner, a moving cone bushing, and a locking bolt. The moving cone liner covers the moving cone and is tightened by screwing the locking bolt. The top of the locking bolt is covered with a dividing cap, and the moving cone bushing is installed between the spherical tile frame and the moving cone.

[0021] Furthermore, the horizontal shaft assembly includes a horizontal shaft, a pinion gear, etc., the eccentric assembly includes a large gear, an eccentric shaft sleeve and a wear-resistant bushing, etc., the large gear is sleeved on the eccentric assembly and connected to the eccentric shaft sleeve, the horizontal shaft is inserted into the horizontal shaft hole of the frame, the pinion gear is installed in the gear cavity of the frame and meshes with the large gear for transmission, one end of the horizontal shaft is connected to the pinion gear for transmission, and the other end is connected to the power source.

[0022] The present invention also provides a method for crushing various product particle sizes, wherein the eccentric assembly is driven to rotate by the horizontal shaft assembly, thereby driving the movable cone assembly to swing in a circle; ensuring that at least one section of the first arc contour in the shaft ring is in a contact and matching state with the eccentric assembly, and adjusting different eccentric distances by rotating the eccentric assembly to switch the first arc contours of different sections of the inner ring of the shaft ring. The movable cone assembly achieves different swing amplitudes according to different eccentric distances, so that the same crusher can crush aggregates of different particle sizes according to the different swing amplitudes of the movable cone assembly.

[0023] Compared with the prior art, the present invention has the following beneficial effects: when the present invention is working, the different arc segments of the inner ring arc of the shaft ring and the outer ring arc of the eccentric sleeve cooperate to make the movable cone swing in the circular process. By rotating the eccentric assembly, the first arc profiles of different segments of the inner ring of the shaft ring are switched to adjust different eccentric distances, which will result in different swing amplitudes of the movable cone. The same crusher can crush aggregates of different particle sizes according to the different swing amplitudes of the movable cone, thereby producing crushed products of different product particle sizes under the same feed condition.

DETAILED DESCRIPTION

[0033] Reference Figure 1-3 A cone crusher capable of producing a variety of product particle sizes comprises a main shaft 2, a spherical support assembly, a frame 1, a horizontal shaft 18 assembly, an eccentric assembly, a movable cone assembly and a fixed cone assembly 6. The main shaft 2 is arranged in the frame 1, the eccentric assembly is sleeved on the main shaft 2, the movable cone assembly is seated on the main shaft 2 through the spherical support assembly, the fixed cone assembly 6 is arranged on the upper part of the movable cone assembly and cooperates with the movable cone assembly to form a crushing chamber, the lower part of the movable cone assembly is sleeved in the eccentric assembly sleeve, and the eccentric assembly is driven to rotate by the horizontal shaft 18 assembly to drive the movable cone assembly to swing in a circle; a detachable shaft ring 15 is arranged at the lower part of the movable cone assembly, the shaft ring 15 is sleeved on the eccentric assembly, the inner ring of the shaft ring 15 and the outer ring of the eccentric assembly form a cooperative drive, and the inner ring of the shaft ring 15 is formed by the intersection of a plurality of first arc contours of the same or different radii that are recessed inward. When the present invention is working, the different radius sizes of the inner ring of the shaft ring 15 cooperate with the eccentric assembly, so that during the circular swing of the movable cone 14, each time the eccentric part of the eccentric assembly switches the first arc profile of the inner ring of the shaft ring 15 with different radius sizes, the movable cone 14 will have different swing amplitudes. Under the condition of meeting the normal use of material crushing, materials of the same size can be input at the same time, and different product particle sizes can be crushed to meet the function of one machine for multiple uses, and the use efficiency of the product is maximized, thereby improving the cost performance of the equipment under the condition of meeting the use requirements.

[0034] Reference Figures 2 to 7 The eccentric assembly is an eccentric sleeve 5 sleeved on the main shaft, and the outer ring of the eccentric sleeve 5 is formed by the intersection of several sections of inwardly protruding second arc contours with the same or different radii.

[0035] The intersection of two adjacent first arc contours has a smooth transition, and the intersection of two adjacent second arc contours has a smooth transition.

[0036] Among them, several segments of the first arc contours use the same center or different centers, and several segments of the second arc contours use the same center.

[0037] Among them, a gap is left between the inner ring of the moving cone assembly and the eccentric assembly, and a non-rigid connection method is adopted for installation.

[0038] Among them, the shaft ring 15 on the moving cone assembly and the eccentric sleeve 5 on the eccentric assembly are always used in pairs, and are mainly adjusted according to different product particle size ranges and grading requirements. The selection method is mostly to match the same eccentric sleeve 5 with different shaft rings 15. During operation, the maximum arc radius of the eccentric sleeve 5 is equal to the maximum arc radius of the shaft ring 15, so as to ensure that the first arc contour of the inner ring of the shaft ring 15 always has at least one point in contact with the second arc contour of the outer ring of the eccentric sleeve 5, so as to ensure that the eccentric distance is continuously changed and adjusted according to the pre-designed requirements.

[0039] Among them, the eccentric sleeve 5 and the collar 15 are designed to cooperate with multiple arc sections. With the rotation in the circumferential direction, the second arc contour at the same position of the eccentric sleeve 5 will alternately contact with the first arc contour of different sections of the collar 15 as the rotation angle changes. Similarly, the first arc contour at the same position of the collar 15 will alternately contact with the second arc contour of each position of the eccentric sleeve 5 as the rotation angle changes. During the full rotation process, the eccentric distance is adjusted and changed many times, so the crushing ratio is also adjusted many times. Since the crushing ratio = incoming material particle size / discharge particle size, when the particle size range of the incoming material particle size is certain, the difference in eccentric distance changes the crushing ratio, which directly affects the difference in discharge particle size. According to the pre-selected collar 15 and eccentric sleeve 5, a better and more reasonable discharge particle size range and grading can be obtained. The specifications of eccentric sleeve 5 include: same arc radius with same center, different arc radius with same center; the specifications of collar 15 include: same arc radius with same center, different arc radius with same center, different arc radius with same center, different arc radius with different centers;

[0040] The selection principle should be followed: the same arc radius with the same center (eccentric sleeve 5) and the same arc radius with different centers (shaft collar 15), the same arc radius with different centers (shaft collar 15), and the different arc radius with different centers (shaft collar 15);

[0041] Concentric different arc radii (eccentric sleeve 5) and concentric same arc radius (shaft collar 15), concentric different arc radii (shaft collar 15), different centers with the same arc radius (shaft collar 15), different centers with different arc radii (shaft collar 15);

[0042] During the matching process between the eccentric sleeve 5 and the collar 15, the maximum arc radius of the eccentric sleeve 5 should be equal to the maximum arc radius of the collar 15. During the circular rotation process, at least one arc is in contact and matching state at each moment. The outer ring of the eccentric sleeve 5 uses arc profiles of different radii, and requires that the intersections of arcs of different segments have a smooth transition. The arc radius in different intervals can be designed as multiple segments with different arc radii to meet more gradation segments with continuous needs. However, the designed arc segments should not reduce the requirements of the processing design too much. The arc profiles of the arc segments will be different if the size of the arc radius is different.

[0043] In this embodiment, the first arc profile of the collar 15 is shown to be four sections, namely R1, R2, R3, and R4. Different first arc profiles can be adjusted to obtain materials with different particle size ranges and different gradations. R1 corresponds to a crushed particle size range of 0-5 mm, R2 corresponds to a crushed particle size range of 5-10 mm, R3 corresponds to a crushed particle size range of 10-20 mm, and R4 corresponds to a crushed particle size range of 20-31.5 mm, thereby adjusting the proportion and gradation of each stage within the particle size range of 0-31.5 mm. At the same time, different values ​​of R1, R2, R3, and R4 can be adjusted, and different eccentric sleeves 5 and collars 15 can be selected to conditionally improve and select material particle sizes within different intervals. Different arc profiles have a smooth transition at the intersection, and the maximum radius size of the collar 15 is equal to the maximum radius size of the eccentric sleeve 5. It is always ensured that during operation, the outer circle arc profile of the eccentric sleeve 5 is in contact with the inner circle arc profile of the collar 15 at least at one point, and the same or different radius arcs use the same center.

[0044] Reference Figure 8 During operation, the moving cone 14 transmits the power source for material crushing, and squeezes and crushes the material by cooperating with the fixed cone. A counterweight block 20 is arranged inside the moving cone assembly to adjust the balance angle of the moving cone to balance the kinetic energy of crushing materials of different particle sizes and ensure that the shaft ring 15 is always in contact with the eccentric sleeve 5.

[0045] To ensure better results, different weight counterweights 20 are arranged at different positions inside the moving cone assembly. Different specifications and models of the shaft ring 15 and the eccentric sleeve 5 are selected, and the installation position of the counterweight 20 in the height direction needs to be adjusted. When the position of the counterweight 20 is different, according to F=m*a (F is force, m is mass, and a is acceleration), F is proportional to m, and M=F*L (M is moment, F is force, and L is the lever arm), it can be seen that M is proportional to L. When the position perpendicular to the F direction is longer from the suspension point, the same moment can be obtained, and the applied force can be smaller. On the contrary, the position perpendicular to the F direction from the suspension point increases, F also increases, and the torque M obtained can be doubled. The principle of adjustment follows the properties and density of the crushed material and the crushing force required for the cohesion between the lattices in the crushed material to avoid over-crushing of the material. The installation method of the counterweight 20 is preferably fixed in the moving cone assembly by magnetic attraction or bolt fastening, which can facilitate fastening, installation and adjustment.

[0046] Reference Figure 1 In order to ensure that the bottom of the moving cone assembly is not interfered by the main shaft 2 during the yaw process of the moving cone assembly, a gap is left between the inner ring of the moving cone assembly and the eccentric assembly, and a non-rigid connection method is used for installation.
