[0027] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and cannot be understood as a limitation of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0028] AsFigure 1 and Figure 2 As shown in FIG. 1 and FIG. 2, the embodiment of the present disclosure provides a shaft assembly convenient to replace, which comprises a bearing seat 2, a rotating shaft 1, a fixing seat 3 and a flange 4. One end of the rotating shaft 1 is rotatably connected with the bearing seat 2. The fixing seat 3 is arranged at the end of the rotating shaft 1 away from the bearing seat 2. The flange 4 comprises a first half ring plate 401 and a second half ring plate 402. The first half ring plate 401 and the second half ring plate 402 are respectively arranged at the end of the fixing seat 3 close to the bearing seat 2. The first half ring plate 401 and the second half ring plate 402 are detachably connected and form a shaft hole, and the rotating shaft 1 penetrates through the shaft hole.

[0029] It can be understood that, since the fixing seat 3 is arranged at the end of the rotating shaft 1 away from the bearing seat 2, and the first half ring plate 401 and the second half ring plate 402 are respectively arranged at the end of the fixing seat 3 close to the bearing seat 2, and the rotating shaft 1 penetrates through the shaft hole formed between the first half ring plate 401 and the second half ring plate 402, the rotating shaft 1 and the flange 4 form an integral structure matched with the shaft hole. Since one end of the rotating shaft 1 is rotatably connected with the bearing seat 2, the flange 4 and the components arranged on the flange 4 can be rotatably arranged by using the rotating shaft 1, thereby meeting the use requirements.

[0030] Meanwhile, since the flange 4 is composed of the detachably connected first half ring plate 401 and the second half ring plate 402, when a fault occurs, the flange 4 and the rotating shaft 1 can be separated by detaching the first half ring plate 401 and the second half ring plate 402, thereby avoiding the disassembly of all the components in the shaft assembly, and effectively improving the working efficiency of the beater when the shaft assembly is applied to the beater.

[0031] It should be noted that, in the related embodiments, the flange 4 is an integral ring plate structure. Since the flange 4 is arranged at the end of the fixing seat 3 close to the bearing seat 2, when the beater malfunctions, not only the disassembly operation of the flange 4 on the fixing seat 3 is needed, but also the disassembly operation of the bearing seat 2 and other components is needed. In the present embodiment, the flange 4 is divided into the detachably connected first half ring plate 401 and the second half ring plate 402. When the beater malfunctions, the flange 4 and the rotating shaft 1 can be separated by detaching the first half ring plate 401 and the second half ring plate 402 and moving the first half ring plate 401 and the second half ring plate 402 transversely, thereby avoiding the disassembly operation of the bearing seat 2 and other components, saving the maintenance time and improving the working efficiency.

[0032] The rotating shaft 1 is used for the rotation of the flange 4 and the components on the flange 4. The specific type of the rotating shaft 1 can be set according to actual needs and there is no restriction. For example, the rotating shaft 1 can be a shaft structure, and the end of the rotating shaft 1 away from the fixed seat 3 can be set with a variable diameter. That is, the diameter of the end of the rotating shaft 1 away from the fixed seat 3 is smaller than the diameter of the end of the rotating shaft 1 close to the fixed seat 3. Thus, the rotating shaft 1 can adapt to the inner ring size of the bearing housing 2.

[0033] The bearing housing 2 is used for the rotation of the rotating shaft 1. The specific type of the bearing housing 2 can be set according to actual needs and there is no restriction. For example, the bearing housing 2 is a seat structure and a bearing is arranged inside the bearing housing 2. The inner ring of the bearing is fitted on the end of the rotating shaft 1 away from the fixed seat 3.

[0034] The fixing seat 3 is used to set the flange 4 on the rotating shaft 1. The specific type of fixing seat 3 can be set according to actual needs and there is no restriction. For example, the fixing seat 3 is a disc-shaped structure and the diameter of the fixing seat 3 is larger than the diameter of the rotating shaft 1. The fixing seat 3 and the rotating shaft 1 are integrally formed.

[0035] The first semi-ring plate 401 and the second semi-ring plate 402 are used to form the flange 4 of the split structure. The specific type of the first semi-ring plate 401 and the second semi-ring plate 402 can be set according to actual needs and there is no limitation. For example, the first semi-ring plate 401 and the second semi-ring plate 402 are both plate structures in the shape of a semi-circular ring, and the first semi-ring plate 401 and the second semi-ring plate 402 are both perpendicular to the rotating shaft 1. The shaft hole formed by the first semi-ring plate 401 and the second semi-ring plate 402 is adapted to fit the rotating shaft 1.

[0036] like Figure 2 As shown, in some embodiments, the flange 4 further includes at least one first connecting assembly, which includes a first connecting plate 403, a second connecting plate 404, a first bolt 405, and a first nut 406. The first connecting plate 403 is disposed on the first semi-ring plate 401, and the second connecting plate 404 is disposed on the second semi-ring plate 402. The shank of the first bolt 405 passes through the first connecting plate 403 and the second connecting plate 404 in sequence. The head of the first bolt 405 abuts against the side of the first connecting plate 403 away from the second connecting plate 404. The first nut 406 is threaded onto the shank of the first bolt 405, and the first nut 406 abuts against the side of the second connecting plate 404 away from the first connecting plate 403.

[0037] It can be understood that, since the shank of the first bolt 405 penetrates the first connecting plate 403 and the second connecting plate 404 in sequence, and the head of the first bolt 405 abuts against the side of the first connecting plate 403 away from the second connecting plate 404, the first nut 406 is threadedly sleeved on the shank of the first bolt 405, and the first nut 406 abuts against the side of the second connecting plate 404 away from the first connecting plate 403, so that the first connecting plate 403 and the second connecting plate 404 can be fixed by the support of the shank of the first bolt 405 and the clamping between the head of the first bolt 405 and the first nut 406, and since the first connecting plate 403 is arranged on the first half-ring plate 401 and the second connecting plate 404 is arranged on the second half-ring plate 402, the first half-ring plate 401 and the second half-ring plate 402 are detachably connected by the at least one first connecting assembly, so that the structure of the flange 4 is stable, and the shaft assembly is convenient to disassemble and assemble.

[0038] It should be noted that the first connecting assembly is used for detachable connection between the first half-ring plate 401 and the second half-ring plate 402, and the number of the first connecting assemblies can be set according to actual needs, which is not limited, for example, the first connecting assemblies can be provided as two groups, and the two groups are respectively used for connecting two ends of the first half-ring plate 401 and the second half-ring plate 402.

[0039] The first connecting plate 403 and the second connecting plate 404 are used for connecting between the first half-ring plate 401 and the second half-ring plate 402, and the specific types of the first connecting plate 403 and the second connecting plate 404 can be set according to actual needs, which is not limited, for example, the first connecting plate 403 and the second connecting plate 404 can both be rectangular plate structures, and the first connecting plate 403 and the second connecting plate 404 are both perpendicular to the tangential direction of the rotating shaft 1.

[0040] The first bolt 405 and the first nut 406 are used for connecting between the first connecting plate 403 and the second connecting plate 404, and the specific types of the first bolt 405 and the first nut 406 can be set according to actual needs, which is not limited. Among them, the first bolt 405 and the first nut 406 can be provided in multiple groups, which is not limited.

[0041] As shown in FIGS. Figure 1 and Figure 2 In some embodiments, the shaft assembly further comprises: a plurality of second connecting assemblies, each second connecting assembly comprising: a second bolt 8, a shank of the second bolt 8 penetrating the flange 4 and being threadedly arranged at one end of the fixed seat 3 close to the bearing seat 2, and a head of the second bolt 8 abutting against the side of the flange 4 close to the bearing seat 2. Among them, the plurality of second bolts 8 are distributed along the circumferential direction of the rotating shaft 1.

[0042] It can be understood that, since the shank of the second bolt 8 penetrates the flange 4 and is threadedly arranged at one end of the fixing base 3 close to the bearing seat 2, and the head of the second bolt 8 abuts against the side of the flange 4 close to the bearing seat 2, the flange 4 formed by the first half ring plate 401 and the second half ring plate 402 can be detachably arranged by the support of the shank of the second bolt 8 and the clamping of the head of the second bolt 8, so as to facilitate the disassembly and assembly of the shaft assembly while ensuring the stable arrangement between the flange 4 and the rotating shaft 1.

[0043] It should be noted that the second bolt 8 is used for fixing the first half ring plate 401 and the second half ring plate 402 on the fixing base 3, and the specific type of the second bolt 8 can be arranged according to actual needs, which is not limited.

[0044] As shown in Figure 2 In some embodiments, the second connecting assembly further comprises: a check wire 9, the check wire 9 is wound between adjacent second bolts 8, and the check wire 9 penetrates the head of each adjacent second bolt 8.

[0045] It can be understood that, since the check wire 9 is wound between adjacent second bolts 8, and the check wire 9 penetrates the head of each adjacent second bolt 8, the second bolt 8 cannot rotate under the pulling and limiting of the check wire 9, so as to avoid loosening of the second bolt 8 due to vibration of the equipment, thereby ensuring higher structural stability of the shaft assembly.

[0046] It should be noted that the check wire 9 is used for bolt loosening prevention by cooperation between adjacent second bolts 8, and the specific type of the check wire 9 can be arranged according to actual needs, which is not limited. For example, the check wire 9 can be a galvanized iron wire, and the check wire 9 is arranged in an "8" shape between adjacent second bolts 8.

[0047] As shown in Figure 3 The present disclosure also provides a belt beater, which comprises: two shaft assemblies according to the present disclosure, a plurality of idlers 5, and a driving mechanism 6. The two shaft assemblies are symmetrically distributed, the idlers 5 are arranged between the flanges 4 of the two shaft assemblies, the plurality of idlers 5 are spaced apart along the circumferential direction of the rotating shaft 1 of the shaft assembly and are used for winding a belt, the driving mechanism 6 is drivingly connected with the rotating shaft 1, and the driving mechanism 6 is used for driving the rotating shaft 1 to rotate, so that the plurality of idlers 5 beat the belt in turn.

[0048] It can be understood that, since the plurality of rollers 5 are arranged between the two flanges 4 of the shaft assembly and are spaced along the circumference of the rotating shaft 1, the driving mechanism 6 is drivingly connected to the rotating shaft 1, so that the driving mechanism 6 can drive the rotating shaft 1 to rotate, thereby driving the plurality of rollers 5 to rotate around the central axis of the rotating shaft 1 by the flanges 4. Thus, when the belt is arranged on the plurality of rollers 5, the overall radial change can be realized by the rotation of the plurality of rollers 5, thereby forming a vibration beating effect on the belt by the radial change, and thereby realizing the cleaning operation.

[0049] In this embodiment, since the flange 4 is composed of the first half ring plate 401 and the second half ring plate 402 which are detachably connected, when a fault occurs, the flange 4 and the rotating shaft 1 can be separated by detaching the first half ring plate 401 and the second half ring plate 402, thereby avoiding the disassembly of all components in the shaft assembly, and thereby effectively improving the operation efficiency of the beater.

[0050] It should be noted that, the plurality of rollers 5 are used to cooperate with the rotation of the rotating shaft 1 to realize the vibration beating on the belt, and the specific type of the roller 5 can be set according to actual needs, which is not limited. For example, the roller 5 can be a combined structure of a sleeve and a roller shaft, the roller shaft is arranged between the two flanges 4, and the sleeve is rotatably arranged on the roller shaft. After the plurality of rollers 5 are arranged between the two flanges 4, the central axis of the whole coincides with the central axis of the rotating shaft 1, and the diameter of the whole is greater than the diameter of the flange 4.

[0051] In this embodiment, when the roller 5 fails, the flange 4 and the rotating shaft 1 can be separated by detaching the first half ring plate 401 and the second half ring plate 402, and then the failed roller 5 can be replaced.

[0052] The driving mechanism 6 is used to drive the rotating shaft 1 to rotate, and the specific type of the driving mechanism 6 can be set according to actual needs, which is not limited.

[0053] As shown in Figure 1 and Figure 2 In some embodiments, the shaft assembly further comprises a plurality of third connecting assemblies, each of the third connecting assemblies comprising a pin shaft 10 and a second nut 11. The pin shaft 10 is connected to the roller 5, and an end of the pin shaft 10 away from the roller 5 penetrates the flange 4. The second nut 11 is threadedly sleeved on the end of the pin shaft 10 away from the roller 5, and the second nut 11 abuts against the side of the flange 4 close to the bearing seat 2.

[0054] It can be understood that, since the pin shaft 10 penetrates the flange 4 at the end away from the roller 5, and the second nut 11 is threadedly sleeved at the end of the pin shaft 10 away from the roller 5, the second nut 11 and the flange 4 abut against the side close to the bearing seat 2, so that the roller 5 is detachably arranged on the flange 4 by the support of the pin shaft 10 and the clamping of the second nut 11, thereby facilitating the disassembly and assembly of the roller 5 while achieving stable arrangement of the roller 5.

[0055] It should be noted that the pin shaft 10 is used for arranging the roller 5 on the flange 4, and the specific type of the pin shaft 10 can be set according to actual needs, which is not limited. For example, the pin shaft 10 is in the shape of a shaft, and the end of the pin shaft 10 away from the roller 5 is provided with external threads matched with the second nut 11.

[0056] The second nut 11 is used for arranging the roller 5 on the flange 4, and the specific type of the second nut 11 can be set according to actual needs, which is not limited.

[0057] As shown in Figure 1 and Figure 2 In some embodiments, the second nut 11 is a slotted nut, and the third connecting assembly further includes an open pin 12 penetrating the pin shaft 10 and the slot of the slotted nut.

[0058] It can be understood that, since the open pin 12 penetrates the pin shaft 10 and the slot of the slotted nut, the second nut 11 and the pin shaft 10 cannot rotate relative to each other under the blocking of the open pin 12, thereby avoiding loosening of the second nut 11 due to vibration of the equipment, and further ensuring higher structural stability of the roller 5.

[0059] It should be noted that the slotted nut is a nut provided with a plurality of slots, and the plurality of slots are distributed along the circumference of the nut at one end of the nut.

[0060] The open pin 12 is used for limiting between the pin shaft 10 and the second nut 11, and the specific type of the open pin 12 can be set according to actual needs, which is not limited.

[0061] As shown in Figure 3 In some embodiments, the driving mechanism 6 includes a driving motor 601, a small pulley 602 and a large pulley 603. The small pulley 602 is sleeved on the rotating shaft of the driving motor 601, and the large pulley 603 is sleeved on the rotating shaft of one shaft assembly. The small pulley 602 and the large pulley 603 are connected by belt transmission.

[0062] It can be understood that, since the small pulley 602 is sleeved on the rotating shaft of the driving motor 601, and the large pulley 603 is sleeved on the rotating shaft 1 of the shaft assembly, the small pulley 602 and the large pulley 603 are connected through belt transmission, so that the driving motor 601 can drive the rotating shaft 1 of the shaft assembly to rotate through the belt transmission between the small pulley 602 and the large pulley 603, thereby realizing the vibration beating of the plurality of rollers 5 on the belt through the rotation of the rotating shaft 1.

[0063] It should be noted that the driving motor 601 serves as a power source for providing power for the vibration beating of the plurality of rollers 5, and the specific type of the driving motor 601 can be set according to actual needs, which is not limited.

[0064] The small pulley 602 and the large pulley 603 are used for speed reduction transmission between the driving motor 601 and the rotating shaft 1, and the specific type of the small pulley 602 and the large pulley 603 can be set according to actual needs, which is not limited. For example, the small pulley 602 and the large pulley 603 are both pulley structures, and the diameter of the small pulley 602 is smaller than that of the large pulley 603. Among them, in order to adapt to the sleeving of the large pulley 603, the two shaft assemblies can be slightly different at the rotating shaft 1. Specifically, the rotating shaft 1 sleeved with the large pulley 603 has a longer small diameter portion, and the rotating shaft 1 not sleeved with the large pulley 603 has a longer large diameter portion.

[0065] As shown in Figure 3 In some embodiments, the beater further comprises a rack 7, and the driving mechanism 6 and the bearing seat 2 of the shaft assembly are arranged on the rack 7 respectively.

[0066] It can be understood that, since the driving mechanism 6 and the bearing seat 2 of the shaft assembly are arranged on the rack 7 respectively, the driving mechanism 6 and the shaft assembly can be supported and protected by the rack 7, and the centralized arrangement of the beater in the belt conveyor and other equipment is facilitated.

[0067] It should be noted that the rack 7 is used for carrying the driving mechanism 6, the shaft assembly and the like, and the specific type of the rack 7 can be set according to actual needs, which is not limited. For example, the rack 7 can be a frame structure close to U-shaped, and the shaft assembly is located on the inner side of the U-shaped structure, and the driving motor 601 is located on the outer side of the U-shaped structure.
