Description

Technical Field

[0001] This application relates to the field of material handling technology, and more specifically, to a drive mechanism and a silo. Background Technology

[0002] Silos are used to store and process bulk materials, such as coal and gypsum. Currently, silos typically include a worktable, cutter head, ratchet, and hydraulic telescopic components. The ratchet has multiple toothed grooves, and the hydraulic telescopic component is mounted on the worktable. During extension and retraction, the movable end of the hydraulic telescopic component abuts against and separates from the toothed grooves on the ratchet on the inner wall of the silo, allowing the worktable to rotate relative to the silo. The cutter head is mounted on the worktable; its rotation drives the cutter head to rotate within the silo, thus unloading the material. However, in actual use, when the volume and weight of the material suddenly increase, the worktable is prone to jamming, causing the movable end of the hydraulic telescopic component to fail to accurately engage with the toothed grooves. Utility Model Content

[0003] The main objective of this application is to provide a drive mechanism and silo to solve the problem in the prior art that the moving end of a hydraulic telescopic component is prone to not accurately abutting against the tooth groove.

[0004] According to one aspect of this application, a drive mechanism is provided, comprising:

[0005] Workbench;

[0006] A drive assembly includes a gear ring, a hydraulic component, and a telescopic component. The gear ring surrounds the outer periphery of the worktable. A first end of the hydraulic component is movably connected to the worktable. Along the length of the hydraulic component, the hydraulic component has a first position where it extends to abut against the gear ring and a second position where it retracts to separate from the gear ring. The telescopic component is telescopically connected between the worktable and the hydraulic component to drive the hydraulic component to swing around the first end.

[0007] When the hydraulic component switches between the first position and the second position and oscillates around the first end, the second end of the hydraulic component opposite to the first end slides along the inner ring of the gear ring to drive the worktable to rotate around the axis of the gear ring.

[0008] Furthermore, the telescopic component includes:

[0009] Fixing part;

[0010] A telescopic part, which is connected to the fixed part and reciprocates along the length direction of the fixed part;

[0011] One of the fixed part and the telescopic part is rotatably connected to the worktable, and the other part is rotatably connected to the hydraulic component.

[0012] Furthermore, the hydraulic component includes a hydraulic cylinder and a piston rod, the piston rod being at least partially located within the hydraulic cylinder and reciprocating relative to the hydraulic cylinder, the end of the piston rod away from the hydraulic cylinder sliding along the inner ring of the gear ring, the length direction of the piston rod being inclined to the radial direction of the gear ring, and the end of the telescopic component away from the worktable being rotatably connected to the hydraulic cylinder via a connector.

[0013] Furthermore, the connector includes:

[0014] A ball groove seat, which is connected to the hydraulic cylinder, has a spherical groove inside.

[0015] A cue stick, one end of which is provided with a ball, the ball being installed in a spherical groove and rollingly connected to the inner wall of the spherical groove, the end of the cue stick away from the ball being connected to the telescopic component.

[0016] Furthermore, the inner ring of the gear ring is provided with a toothed groove, and the end of the telescopic component away from the worktable is detachably connected to a snap-fit ​​structure. When the hydraulic component is in the first position, the snap-fit ​​structure engages with the toothed groove; and / or,

[0017] Along the radial direction of the toothed ring, a wear-resistant layer is provided on the surface of the toothed ring near the worktable, and the wear-resistant layer is in contact with the surface of the toothed ring.

[0018] Furthermore, the snap-fit ​​structure includes:

[0019] A caliper is detachably connected to the end of the telescopic component away from the worktable, and a mounting groove is provided through the end of the caliper away from the telescopic component along the width direction of the hydraulic component;

[0020] The rod body has its opposite sides passing through the two opposite side walls of the mounting groove. The rod body is arranged close to the opening of the mounting groove. When the hydraulic component is in the first position, at least part of the opposite sides of the toothed ring are located in the mounting groove, and the rod body abuts against the bottom of the toothed groove.

[0021] Furthermore, the toothed ring is a circular ring structure, the depth direction of the tooth groove is inclined to the radial direction of the toothed ring, the snap-fit ​​structure is provided with a protrusion, and the side wall of the tooth groove is provided with a snap-fit ​​groove that matches the protrusion.

[0022] The slot includes a guide section and a locking section that are interconnected. The locking section extends along the depth direction of the tooth groove, and the guide section extends in a direction perpendicular to the locking section and is arranged close to the opening of the slot. The protrusion has a locking position that engages with the locking section and an unlocking position that disengages from the locking section.

[0023] Furthermore, the hydraulic components include at least two sets, which are spaced apart on the worktable. Each of the at least two sets of hydraulic components is connected to a hydraulic pipe, which is in communication with the hydraulic cylinder.

[0024] The drive mechanism also includes a liquid storage tank, which is disposed on the worktable. A hydraulic pump and a reversing component are disposed on the liquid storage tank. The hydraulic pump is connected to the interior of the liquid storage tank and the reversing component. The hydraulic pipes corresponding to each hydraulic component are connected to the reversing component. The reversing component and the hydraulic pump are electrically connected to the controller.

[0025] Furthermore, a pressure sensor is provided on the liquid storage tank, the pressure sensor being used at least to detect the pressure inside the hydraulic pipe, and the pressure sensor is electrically connected to the controller.

[0026] On the other hand, this application also provides a silo, the silo including a main body and the aforementioned drive mechanism, the drive mechanism being disposed inside the main body, and the gear ring being fixedly connected to the inner wall of the main body.

[0027] In this application, when the extended second end of the hydraulic component abuts against the gear ring, the hydraulic component is in the first position. Since the gear ring is fixed to the inner wall of the silo, it is relatively stationary. As the hydraulic component continues to extend, the gear ring applies a force to the second end of the hydraulic component, pushing the first end of the hydraulic component and the worktable to rotate around the axis of the gear ring. During the rotation of the first end of the hydraulic component around the axis of the gear ring, the length of the telescopic component decreases. The telescopic component provides stable support to the hydraulic component, ensuring its high stability. The reduced length of the telescopic component also ensures that the first end of the hydraulic component can rotate smoothly around the axis of the gear ring. During the rotation of the worktable, the cutter head on the worktable, equivalent to the silo, rotates, allowing for more comprehensive unloading of the material inside the silo, ensuring more thorough material removal.

[0028] When the hydraulic component extends to its limit position, the second end of the hydraulic component retracts to separate from the gear ring. The telescopic component can extend to drive the second end of the hydraulic component to swing around the first end, causing the second end of the hydraulic component to slide along the inner ring of the gear ring. This allows the second end of the hydraulic component to swing rapidly to adjust its position relative to the gear ring, so that the extended second end of the hydraulic component can accurately abut against the inner ring of the gear ring again to drive the worktable to rotate.

[0029] When the hydraulic component switches between the first and second positions, the telescopic component extends and retracts, driving the second end of the hydraulic component to swing around the first end. The telescopic component provides stable support for the hydraulic component and adjusts the position of the second end relative to the gear ring, ensuring that the extended second end of the hydraulic component accurately abuts against the gear ring. During the rotation of the worktable around the axis of the gear ring, if the volume or weight of the material suddenly increases, the force exerted on the worktable by the material will suddenly increase, potentially causing the worktable to jam. This application addresses this issue by incorporating a telescopic component, which allows the telescopic component to adjust the position of the second end relative to the gear ring, ensuring that the second end accurately abuts against the gear ring, thereby stably driving the rotation of the worktable and effectively improving the reliability and efficiency of the silo unloading process. Furthermore, the first end of the hydraulic component is movably connected to the worktable, allowing it to move relative to the worktable. This ensures that the first end of the hydraulic component can smoothly rotate around the axis of the worktable, and also ensures that the second end can smoothly swing around the first end to slide along the inner ring of the gear ring, driving the worktable to rotate around the axis of the gear ring.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0040] like Figures 1 to 4 As shown, this application provides a drive mechanism. The drive mechanism includes a worktable 10 and a drive assembly 20. The drive assembly 20 includes a gear ring 21, a hydraulic component 22, and a telescopic component 23. The gear ring 21 surrounds the outer periphery of the worktable 10. The first end of the hydraulic component 22 is movably connected to the worktable 10. Along the length direction of the hydraulic component 22 (e.g., along the length direction of the hydraulic component 22...) Figure 3(In the direction indicated by the middle arrow X), the hydraulic component 22 has a first position extended to abut against the toothed ring 21 and a second position retracted to separate from the toothed ring 21. A telescopic component 23 is telescopically connected between the worktable 10 and the hydraulic component 22 to drive the hydraulic component 22 to oscillate around its first end. When the hydraulic component 22 switches between the first and second positions and oscillates around its first end, the second end of the hydraulic component 22, opposite to the first end, slides along the inner ring of the toothed ring 21 to drive the worktable 10 to rotate around the axis of the toothed ring 21.

[0041] In this embodiment, when the extended second end of the hydraulic component 22 abuts against the gear ring 21, the hydraulic component 22 is in the first position. Since the gear ring 21 is fixed to the inner wall of the silo, it is relatively stationary. As the hydraulic component 22 continues to extend, the gear ring 21 applies a force to the second end of the hydraulic component 22 to push the first end of the hydraulic component 22 and the worktable 10 to rotate around the axis of the gear ring 21. During the rotation of the first end of the hydraulic component 22 around the axis of the gear ring 21, the length of the telescopic component 23 decreases. The telescopic component 23 can provide stable support to the hydraulic component 22, ensuring that the hydraulic component 22 has high stability. The reduction in the length of the telescopic component 23 also ensures that the first end of the hydraulic component 22 can rotate smoothly around the axis of the gear ring 21. During the rotation of the worktable 10, the cutter head 11 on the worktable 10 will drive the silo to rotate, which is equivalent to the rotation of the silo. The cutter head 11 can perform a more comprehensive unloading operation on the material in the silo, so that the material is more thoroughly unloaded from the silo.

[0042] When the hydraulic component 22 extends to its limit position, the second end of the hydraulic component 22 retracts to separate from the gear ring 21. The telescopic component 23 can extend to drive the second end of the hydraulic component 22 to swing around the first end, causing the second end of the hydraulic component 22 to slide along the inner ring of the gear ring 21. This allows the second end of the hydraulic component 22 to swing rapidly to adjust its position relative to the gear ring 21, so that the extended second end of the hydraulic component 22 can accurately abut against the inner ring of the gear ring 21 again to drive the worktable 10 to rotate.

[0043] When the hydraulic component 22 switches between the first and second positions, the telescopic component 23 extends and retracts, driving the second end of the hydraulic component 22 to swing around the first end. The telescopic component 23 provides stable support for the hydraulic component 22 and adjusts the position of the second end relative to the gear ring 21, ensuring that the extended second end of the hydraulic component 22 accurately abuts against the gear ring 21. During the rotation of the worktable 10 around the axis of the gear ring 21, if the volume or weight of the material suddenly increases, the force exerted by the material on the worktable 10 will suddenly increase, making the worktable 10 prone to jamming. In this embodiment, by setting the telescopic component 23, the position of the second end relative to the gear ring 21 can be adjusted, ensuring that the second end accurately abuts against the gear ring 21, thereby stably driving the rotation of the worktable 10 and effectively improving the reliability and efficiency of the silo unloading process. In addition, the first end of the hydraulic component 22 is movably connected to the worktable 10, so that the first end of the hydraulic component 22 can move relative to the worktable 10, ensuring that the first end of the hydraulic component 22 can smoothly rotate around the axis of the worktable 10, and also ensuring that the second end can smoothly swing around the first end to slide along the inner ring of the gear ring 21, and drive the worktable 10 to rotate around the axis of the gear ring 21.

[0044] In the prior art, to enable the worktable 10 to rotate continuously, two sets of hydraulic components 22 are typically installed on the worktable 10. These two sets of hydraulic components 22 extend and retract alternately to drive the worktable 10 to rotate continuously. During the alternating extension and retraction of the two sets of hydraulic components 22, when the first set of hydraulic components 22 pushes the worktable 10 to rotate, the second set of hydraulic components 22 is separated from the gear ring 21 and rotates with the worktable 10, causing the position of the second set of hydraulic components 22 to change relative to the gear ring 21. For the worktable 10 to rotate continuously, the extended second set of hydraulic components 22 needs to be accurately aligned and abut against the tooth groove 210 of the inner ring of the gear ring 21 to drive the worktable 10 to rotate. In other words, the prior art places high demands on the coordination of the two sets of hydraulic components 22. Compared to the prior art, in this embodiment, when multiple sets of hydraulic components 22 are installed on the worktable 10, the telescopic component 23 of this embodiment can adjust the position of its second end relative to the gear ring 21, reducing the coordination difficulties between multiple sets of hydraulic components 22 and thus reducing the risk of downtime or damage to the drive mechanism.

[0045] In one embodiment, the telescopic component 23 includes a fixed portion 231 and a telescopic portion 232. The telescopic portion 232 is connected to the fixed portion 231 and reciprocates along the length direction of the fixed portion 231. The fixed portion 231 is rotatably connected to the worktable 10, and the telescopic portion 232 is rotatably connected to the hydraulic component 22.

[0046] The reciprocating movement of the telescopic part 232 along the length of the fixed part 231 allows for flexible adjustment of the relative position between the hydraulic component 22 and the gear ring 21. When the material weight changes or the worktable 10 experiences a slight shift, the telescopic part 232 compensates for the position of the second end of the hydraulic component 22 relative to the gear ring 21 by extending and retracting, ensuring that the hydraulic component 22 accurately abuts against the gear ring 21. The fixed part 231 is rotatably connected to the worktable 10, allowing the telescopic part 23 to rotate synchronously with the worktable 10. This ensures that a reasonable force application angle is maintained throughout the movement of the worktable 10, preventing stress concentration and component damage caused by angular deviations in the telescopic part 23. The telescopic part 232 is rotatably connected to the hydraulic component 22, giving it a certain degree of freedom of movement. When the hydraulic component 22 switches between the first and second positions, the telescopic part 232 can freely adjust its posture. The telescopic part 23 enhances the flexibility and fault tolerance of the drive mechanism, effectively improving the stability and reliability of its operation.

[0047] Specifically, the telescopic component 23 can be configured as one of the following: a hydraulic telescopic component, a screw telescopic component, etc.

[0048] In another embodiment, the fixed part 231 is rotatably connected to the hydraulic component 22, and the telescopic part 232 is rotatably connected to the worktable 10. In one embodiment, the hydraulic component 22 includes a hydraulic cylinder 221 and a piston rod 222. The piston rod 222 is at least partially located within the hydraulic cylinder 221 and reciprocates relative to the hydraulic cylinder 221. The end of the piston rod 222 away from the hydraulic cylinder 221 slides along the inner ring of the gear ring 21. The length direction of the piston rod 222 is inclined to the radial direction of the gear ring 21. The end of the telescopic part 232 away from the worktable 10 is rotatably connected to the hydraulic cylinder 221 via a connector. The reciprocating movement of the piston rod 222 within the hydraulic cylinder 221 allows for precise control of the extension and retraction stroke of the piston rod 222, ensuring the accuracy of the piston rod 222's contact and separation action with the gear ring 21. The piston rod 222 is inclined radially to the gear ring 21. During the process of the piston rod 222 abutting against the gear ring 21 to push the worktable 10 to rotate, the piston rod 222 will be subjected to a tangential component force, ensuring that the worktable 10 can rotate around the axis of the gear ring 21 and improving the rotation efficiency of the worktable 10. The telescopic component 23 is rotatably connected to the hydraulic cylinder 221 through a connector. During the swinging process of the hydraulic component 22, the telescopic component 23 can flexibly adjust its posture. The telescopic component 23 can adapt to the changing relative position between the telescopic component 23 and the hydraulic component 22, which is beneficial to improving the stability and reliability of the telescopic component 23 and the hydraulic component 22.

[0049] The connecting components include a ball groove seat and a ball rod. The ball groove seat is connected to the hydraulic cylinder 221 and has a spherical groove. One end of the ball rod has a ball that is installed in the spherical groove and rolls with the inner wall of the groove. The end of the ball rod away from the ball is connected to the telescopic component 23. The rolling connection between the ball and the spherical groove gives the telescopic component 23 a high degree of rotational freedom, allowing it to flexibly adjust its posture and enabling the hydraulic component 22 to effectively compensate for positional deviations caused by the rotation of the worktable 10 or material impact, thus ensuring that the piston rod 222 accurately abuts against the inner ring of the gear ring 21. The rolling connection between the ball and the spherical groove reduces frictional resistance and wear between them, extending the service life of the ball groove seat and the ball rod. Furthermore, when sudden changes in material weight cause the worktable 10 to jam or experience uneven force, the connecting components can adaptively rotate to alleviate stress concentration, preventing damage to the hydraulic component 22 and the telescopic component 23 from rigid impacts, thus improving the stability and reliability of the drive mechanism during the unloading process.

[0050] In one embodiment, the inner ring of the gear ring 21 is provided with a toothed groove 210. The end of the telescopic member 23 away from the worktable 10 is detachably connected to a snap-fit ​​structure. When the hydraulic member 22 is in the first position, the snap-fit ​​structure engages with the toothed groove 210. The second end of the hydraulic member 22 abuts against one toothed groove 210 of the inner ring of the gear ring 21, causing the worktable 10 to rotate about the axis of the gear ring 21. Subsequently, the hydraulic member 22 retracts and separates from the gear ring 21, and the telescopic member 23 drives the hydraulic member 22 to rotate about the first end, causing the second end to swing relative to the gear ring 21, ensuring that the extended second end of the hydraulic member 22 accurately abuts against the other toothed groove 210. The toothed groove 210 can engage with the snap-fit ​​structure; when the hydraulic member 22 is in the first position abutting against the gear ring 21, the snap-fit ​​structure can be confined within the toothed groove 210, effectively preventing the hydraulic member 22 from slipping out of the toothed groove 210 during the rotation of the worktable 10. In applications requiring heavy materials and high driving force, the engagement of the toothed groove 210 with the snap-fit ​​structure enhances the connection stability between the hydraulic component 22 and the toothed ring 21, improving the reliability of the drive mechanism. The snap-fit ​​structure is detachably connected to the end of the telescopic component 23 furthest from the worktable 10, allowing for quick disassembly and replacement, reducing maintenance costs and downtime of the drive mechanism.

[0051] The locking structure includes a clamp 211 and a rod 212. The clamp 211 is detachably connected to the end of the telescopic component 23 away from the worktable 10. Along the width direction of the hydraulic component 22 (e.g., Figure 3(In the direction indicated by the middle arrow Y), a mounting groove is provided through the end of the caliper 211 away from the telescopic component 23. The opposite sides of the rod 212 pass through the opposite side walls of the mounting groove. The rod 212 is arranged near the opening of the mounting groove. When the hydraulic component 22 is in the first position, at least part of the opposite sides of the toothed ring 21 are located within the mounting groove, and the rod 212 abuts against the bottom of the toothed groove 210. The caliper 211 is detachably connected to the telescopic component 23, facilitating quick installation and replacement of the caliper 211. When the hydraulic component 22 is in the first position, the mounting groove clamps the axial sides of the toothed ring 21 to limit the caliper 211 onto the toothed ring 21, effectively preventing misalignment or disengagement of the toothed ring 21 and the locking structure in the abutting state, thus improving the stability of the hydraulic component 22 during the telescopic process. The rod 212 can precisely abut against the bottom of the tooth groove 210, ensuring that the rod 212 is stably limited in the tooth groove 210, thus ensuring that the drive mechanism has high reliability.

[0052] In one embodiment, the toothed ring 21 is a circular ring structure, the depth direction of the tooth groove 210 is inclined to the radial direction of the toothed ring 21, and a protrusion 213 is provided on the snap-fit ​​structure. A slot adapted to the protrusion 213 is formed on the sidewall of the tooth groove 210. The slot includes a guide section 214 and a locking section 215 that communicate with each other. The locking section 215 extends along the depth direction of the tooth groove 210, and the guide section 214 extends in a direction perpendicular to the locking section 215 and is arranged near the opening of the slot. The protrusion 213 has a locked position where it is engaged with the locking section 215 and an unlocked position where it is disengaged from the locking section 215. The groove 210 is inclined in the depth direction to the radial direction of the toothed ring 21. When the snap-fit ​​structure approaches the toothed ring 21, the guide section 214 can obliquely guide the protrusion 213, ensuring that the protrusion 213 can accurately enter the guide section 214 and quickly and smoothly enter the locking section 215, improving the connection reliability between the snap-fit ​​structure and the groove 210. After the protrusion 213 slides along the guide section 214 to the locking section 215, the locking section 215 is along the depth direction of the groove 210, so that the protrusion 213 can be firmly locked in the locking section 215, effectively preventing the snap-fit ​​structure from disengaging from the groove 210 when the hydraulic component 22 performs an elongation movement, ensuring that the hydraulic component 22 can reliably drive the worktable 10 to rotate. When the volume and weight of the material suddenly increase, the groove can be stably locked together with the protrusion 213, ensuring the stable and efficient operation of the drive mechanism. It is understood that the toothed ring 21 can also be set as a rectangular structure, a polygonal structure, etc., and this embodiment is not limited to it.

[0053] In one embodiment, the hydraulic components 22 include at least two sets, which are spaced apart on the worktable 10. Each set of hydraulic components 22 is connected to a hydraulic pipe, which communicates with the hydraulic cylinder 221. The drive mechanism also includes a liquid storage tank 40. The liquid storage tank 40 is located on the worktable 10 and is equipped with a hydraulic pump 50 and a reversing component 60. The hydraulic pump 50 is connected to both the interior of the liquid storage tank 40 and the reversing component 60. The hydraulic pipes corresponding to each hydraulic component 22 are connected to the reversing component 60. The reversing component 60 and the hydraulic pump 50 are electrically connected to a controller. The liquid storage tank 40 stores hydraulic oil, which may be phosphate ester-based hydraulic oil. The hydraulic oil flows into or out of the hydraulic cylinder 221 sequentially through the hydraulic pump 50, the reversing component 60, and the hydraulic pipes. Specifically, in this embodiment, two sets of hydraulic components 22 are provided, namely a first set of hydraulic components 22 and a second set of hydraulic components 22.

[0054] The first set of hydraulic components 22 is described below. The piston rod 222 of the first set of hydraulic components 22 divides the hydraulic cylinder 221 into two chambers, with hydraulic oil disposed in each chamber. The first chamber is connected to the first hydraulic pipe 31, and the end of the first hydraulic pipe 31 away from the first chamber is connected to the first opening 35 of the reversing member 60. The second chamber is connected to the second hydraulic pipe 32, and the end of the second hydraulic pipe 32 away from the second chamber is connected to the second opening 36 of the reversing member 60. The reversing member 60 also has a main opening, which is connected to the hydraulic pump 50. The end of the hydraulic pump 50 away from the main opening is connected to the inside of the liquid storage tank 40. The hydraulic pump 50 drives the hydraulic oil in the liquid storage tank 40 to flow through the main opening, the first opening 35, and the first hydraulic pipe 31 into the first chamber. The hydraulic pump 50 can also drive the hydraulic oil in the first chamber to flow back into the liquid storage tank 40. Similarly, hydraulic pump 50 can drive hydraulic oil from liquid storage tank 40 into the second chamber, and hydraulic pump 50 can drive hydraulic oil from the second chamber back into liquid storage tank 40. By adjusting the amount of hydraulic oil in the first and second chambers, the position of piston rod 222 relative to hydraulic cylinder 221 can be adjusted, thereby driving piston rod 222 to reciprocate relative to hydraulic cylinder 221.

[0055] Understandably, the third hydraulic pipe 33 on the second set of hydraulic components 22 is connected to the third opening 37 on the reversing member 60, and the fourth hydraulic pipe 34 on the second set of hydraulic components 22 is connected to the fourth opening 38 on the reversing member 60. The reversing member 60 is equipped with multiple valves, each corresponding to one of the first hydraulic pipe 31, the second hydraulic pipe 32, the third hydraulic pipe 33, and the fourth hydraulic pipe 34. The controller can individually control the on / off state of the first hydraulic pipe 31, the second hydraulic pipe 32, the third hydraulic pipe 33, and the fourth hydraulic pipe 34, as well as the flow direction of the hydraulic oil, by controlling the hydraulic pump 50 and the valves. The hydraulic pipes of the first set of hydraulic components 22 are connected in parallel to the hydraulic pipes of the second set of hydraulic components 22 on the reversing member 60. When one set of hydraulic components 22 fails, the other set of hydraulic components 22 can still drive the worktable 10 to rotate.

[0056] In one embodiment, a pressure sensor 70 is installed on the liquid storage tank 40. The pressure sensor 70 is used to detect the pressure within the hydraulic pipe and is electrically connected to the controller. The pressure sensor 70 monitors the pressure within the hydraulic pipe in real time, accurately capturing pressure fluctuations during the operation of the drive mechanism, and can quickly respond to and feedback pressure data within the hydraulic pipe. The pressure sensor 70 and the controller work together to achieve intelligent regulation. When the pressure exceeds a preset threshold, the controller can automatically adjust the extension and retraction speed of the hydraulic component 22, etc., to avoid component damage or other malfunctions caused by excessive pressure. Through continuous analysis of pressure data, potential problems with the hydraulic component 22 can be predicted in advance, facilitating timely intervention by maintenance personnel, reducing the risk of sudden downtime, improving equipment operating efficiency and safety, and providing data support for optimizing the parameters of the hydraulic component 22 and extending the service life of the equipment.

[0057] In one embodiment, a wear-resistant layer is provided on the surface of the gear ring 21 near the worktable 10 along the radial direction of the gear ring 21, and the wear-resistant layer is in contact with the surface of the gear ring 21. Frequent contact and friction between the hydraulic component 22 and the gear ring 21 can easily cause wear on the surface of the gear ring 21, affecting driving accuracy and stability. The wear-resistant layer effectively shares this wear; its high hardness and abrasion resistance significantly reduce the direct wear between the gear ring 21 and the hydraulic component 22, extending the service life of the gear ring 21, reducing the frequency of replacement due to component wear, and lowering maintenance costs. The gear ring 21 is formed by sequentially splicing multiple plates, with adjacent plates detachably connected.

[0058] On the other hand, this application embodiment also provides a silo, which includes a main body and the aforementioned drive mechanism. The drive mechanism is disposed inside the main body, and the gear ring 21 is fixedly connected to the inner wall of the main body. This silo includes all the technical effects of the aforementioned drive mechanism. Since the technical effects of the drive mechanism have been described in detail above, they will not be repeated here.

[0059] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0060] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0061] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
