Description

Technical Field

[0001] This utility model relates to the field of environmental protection machinery and equipment technology, and more specifically, to a power transmission and switching mechanism for an automatic sludge removal device. Background Technology

[0002] In existing tracked automatic sludge removal devices, a single power source (such as a turbine drive shaft) typically drives both the traveling mechanism (tracks) and the auger sludge crushing mechanism simultaneously via a gear transmission mechanism. However, in actual pond bottom sludge removal operations, situations often arise where localized areas of sludge become abnormally compacted and accumulate excessively thickly. If the tracks are continuously and forcibly driven in such cases, the following situations may occur: 1. The entire device becomes stuck in the sludge and cannot move, or even damages the tracks or transmission components; 2. Excessive traveling resistance consumes too much power, affecting the auger crushing effect; 3. The entire device needs to be repeatedly started and stopped, making operation cumbersome and inefficient.

[0003] Therefore, there is an urgent need for a mechanism that enables a tracked automatic dredging device to maintain continuous crushing power while moving by cutting off the power of the traveling mechanism. Utility Model Content

[0004] The purpose of this utility model is to provide a power transmission and switching mechanism for an automatic sludge removal device. When the tracked automatic sludge removal device encounters a thick layer of sludge during the sludge removal process, the power transmission of the traveling mechanism is cut off, causing the device to stop moving. At the same time, the spiral sludge-crushing mechanism continues to operate at full power to break up the sludge. After the sludge is broken up and absorbed and the resistance is reduced, the power of the traveling mechanism can be remotely restored, allowing the tracked automatic sludge removal device to continue moving and removing sludge. This significantly improves the adaptability of the tracked automatic sludge removal device to complex working conditions and its sludge removal efficiency.

[0005] To achieve the purpose of this utility model, the technical solution adopted is as follows: a power transmission and switching mechanism for an automatic sludge removal device, including a rotating shaft and a bushing that are plugged into each other. An input drive gear for driving the spiral sludge removal mechanism is fixedly installed on the rotating shaft. A transmission gear for driving the travel mechanism is fixedly installed on the bushing. An output driven gear that can move axially but cannot rotate is also installed on the bushing. The opposing surfaces of the output driven gear and the input drive gear are provided with meshing teeth that can mesh with each other. The device also includes a drive mechanism for driving the output driven gear to move axially on the bushing.

[0006] Furthermore, a return spring is also fitted on the bushing, with its two ends abutting against the transmission gear and the output driven gear, respectively.

[0007] Furthermore, it also includes a limiting block fixedly installed on the outside of the bushing, with the extended end of the limiting block sleeved on the bushing, and the two ends of the return spring respectively pressing against the limiting block and the output driven gear.

[0008] Furthermore, the drive mechanism includes a release mechanism mounted on the outside of the bushing and through a hinge seat, the movable end of the release mechanism engaging with the output driven gear; the drive mechanism also includes a linear drive structure mounted on the outside of the bushing and through a hinge seat, the output end of the linear drive structure being hinged to the release mechanism.

[0009] Furthermore, the outer circumference of the output driven gear is provided with an annular groove, and the movable end of the tripping mechanism extends into the annular groove.

[0010] Furthermore, the linear drive structure is a hydraulic cylinder or a pneumatic cylinder.

[0011] Furthermore, the input end of the linear drive structure is connected to the remote control system of the automatic sludge removal device.

[0012] Furthermore, it also includes a housing, in which the input drive gear, transmission gear, output driven gear, and drive mechanism are all installed.

[0013] The beneficial effects of this utility model are: In this invention, the output driven gear can be driven by a power mechanism, allowing the output driven gear and the input driving gear to mesh and separate as needed. This enables transmission or disconnection between the bushing and the rotating shaft, and between the spiral sludge-shredding mechanism and the traveling mechanism. When the tracked automatic sludge dredging device encounters a thick layer of sludge during dredging, the power transmission of the traveling mechanism is cut off, stopping the device. At the same time, the spiral sludge-shredding mechanism continues to operate at full power to break up the sludge. After the sludge is broken up and absorbed, and the resistance is reduced, the power of the traveling mechanism can be remotely restored, allowing the tracked automatic sludge dredging device to continue dredging. This significantly improves the adaptability of the tracked automatic sludge dredging device to complex working conditions and its dredging efficiency.

[0014] This utility model has a compact structure, is easy to operate, and has high reliability. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings.

[0019] It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 As shown, the present invention provides a power transmission and switching mechanism for an automatic sludge removal device, comprising a rotating shaft 9 and a bushing 6. The bushing 6 is fitted onto the rotating shaft 9, and the bushing 6 and the rotating shaft 9 are rotatably engaged. The input end of the rotating shaft 9 is connected to the power source of the automatic sludge removal device, and the rotating shaft 9 is connected to the spiral sludge removal mechanism via gear transmission. An input drive gear 1 is fixedly installed on the rotating shaft 9, and the input drive gear 1 is a face gear. A transmission gear 8 is fixedly installed on the bushing 6, so that the rotation of the transmission gear 8 and the bushing 6 is synchronized, and the transmission gear 8 is connected to the traveling mechanism. For example, the transmission gear 8 meshes with the input gear on the traveling mechanism, and the rotation of the transmission gear 8 drives the input gear on the traveling mechanism to rotate, thereby causing the traveling mechanism to rotate, and the automatic sludge removal device to move forward or backward.

[0021] The bushing 6 is also equipped with an output driven gear 2, which can move axially on the bushing 6 but cannot rotate on it. To ensure the installation of the output driven gear 2, a long groove along its axial direction can be formed on the outer wall of the bushing 6, and a flat key that slides with the long groove is installed on the inner hole of the output driven gear 2. To prevent the output driven gear 2 from directly disengaging from the bushing 6 when moving on it, neither end of the long groove penetrates the end face of the bushing 6. The output driven gear 2 is also a face gear. When the output driven gear 2 moves toward the input driving gear 1 and engages with the input driving gear 1, the output driven gear 2 and the input driving gear 1 can mesh through their meshing teeth. Thus, when the output driven gear 2 and the input driving gear 1 are engaged, the input driving gear 1 can drive the output driven gear 2 to rotate synchronously. This causes the bushing 6 and the transmission gear 8 to rotate synchronously. The transmission gear 8 can then drive the input gear on the traveling mechanism to rotate, thereby allowing the traveling mechanism to rotate and enabling the automatic sludge removal device to move forward or backward normally.

[0022] To ensure that the output driven gear 2 moves axially on the bushing 6, the power transmission and switching mechanism of the automatic sludge removal device also includes a drive mechanism. The drive mechanism can drive the output driven gear 2 to move axially on the bushing 6, ensuring that the output driven gear 2 engages or disengages from the input driving gear 1, so that the spiral sludge removal mechanism and the traveling mechanism on the automatic sludge removal device can operate simultaneously, or the spiral sludge removal mechanism on the automatic sludge removal device can operate independently.

[0023] In this invention, to prevent impurities from affecting the transmission between the input drive gear 1 and the output driven gear 2, a housing (not shown in the figure) can also be provided in the power transmission and switching mechanism of the automatic sludge removal device. In this case, the drive mechanism can be installed in the housing, and the bushing 6 can be rotatably supported in the housing by means of bearing seats, etc. The inner end of the rotating shaft 9 that houses the input drive gear 1 extends into the housing; at the same time, the input shaft of the traveling mechanism extends into the housing, so that the input gear on the input shaft of the traveling mechanism meshes with the transmission gear 8 on the bushing 6.

[0024] In this invention, to ensure that the output driven gear 2 remains stable after moving on the bushing 6 and to enable the output driven gear 2 to automatically reset after losing the drive of the drive mechanism, a reset spring 5 is also fitted on the bushing 6. One end of the reset spring 5 is pressed against the output driven gear 2, and the other end of the reset spring 5 is pressed against the transmission gear 8. When the spiral screed mechanism and the traveling mechanism need to operate simultaneously, the drive mechanism removes the drive of the output driven gear 2. At this time, the reset spring 5 pushes the output driven gear 2 on the bushing 6 towards the input driving gear 1 through its own elasticity, so that the output driven gear 2 and the input driving gear 1 are engaged, thereby achieving transmission through the engagement of the output driven gear 2 and the input driving gear 1.

[0025] In this invention, a limiting block 7 extending towards the bushing 6 can be fixedly installed on the inner wall of the housing, and a through hole can be opened on the limiting block 7 so that the bushing 6 can directly pass through the through hole on the limiting block 7 during installation. At this time, the through hole on the limiting block 7 and the bushing 6 are in clearance fit. Of course, a bearing can also be installed in the through hole of the limiting block 7, so that the bushing 6 passes through and is installed in the bearing. When the limiting block 7 is installed on the inner wall of the housing and the bushing 6 passes through and is installed on the limiting block 7, one end of the return spring 5 abuts against the limiting block 7, and the other end of the return spring 5 abuts against the output driven gear 2.

[0026] In this invention, to ensure the driving of the output driven gear 2, the drive structure includes a release mechanism 3 mounted on the inner wall of the housing via a hinged seat. The movable end of the release mechanism 3 engages with the output driven gear 2, allowing the release mechanism 3 to swing within the housing, driving the output driven gear 2 to move linearly on the bushing 6. This allows the output driven gear 2 to either engage with or move away from the input driving gear 1. To further ensure the swinging of the release mechanism 3, a linear drive structure 4 is also hinged to the inner wall of the housing. The output end of the linear drive structure 4 is hinged to the release mechanism 3, thus controlling the swinging of the release mechanism 3.

[0027] To facilitate the driving of the output driven gear 2 by the tripping mechanism 3, an annular groove is provided on the outer circular surface of the output driven gear 2. The movable end of the tripping mechanism 3 extends into the annular groove, so that there is no need for any connecting structure between the movable end of the tripping mechanism 3 and the annular groove. This ensures that the subsequent rotation of the output driven gear 2 will not affect the tripping mechanism 3, and the tripping mechanism 3 will not hinder the rotation of the output driven gear 2.

[0028] In this utility model, the release mechanism 3 can also be replaced by a shift fork mechanism. The drive of the shift fork mechanism can still be accomplished by a linear drive structure 4. In this case, the shift fork mechanism can be inserted into the annular groove.

[0029] In this invention, even as the output driven gear 2 approaches or moves away from the input driving gear 1, the force exerted by the output driven gear 2 on the bushing 6 can be entirely derived from the tripping mechanism 3 or the shift fork mechanism. The return spring 5 can still play a role in the stability of the output driven gear 2 on the bushing 6 and will not affect the normal operation of this invention.

[0030] In this utility model, the linear drive structure 4 is a hydraulic cylinder or a pneumatic cylinder. Of course, a hydraulic cylinder can be preferred in this utility model. The hydraulic oil of the hydraulic cylinder can be directly obtained from the original hydraulic system on the automatic sludge removal device, so there is no need to add additional hydraulic or pneumatic equipment.

[0031] In this invention, to facilitate the control of the linear drive structure 4, the reversing valve on the linear drive structure 4 can be directly connected to the remote control system of the automatic sludge removal device.

[0032] The working principle of this utility model is as follows: (1) Power transmission status (default / engaged): The linear drive structure 4 resets, which in turn drives the tripping mechanism 3 to reset. The tripping mechanism 3 drives the output driven gear 2 to move towards the input driving gear 1 on the bushing 6. With the help of the spring force of the reset spring 5, the output driven gear 2 moves closer to and engages with the input driving gear 1. The output driven gear 2 meshes with the input driving gear 1. At this time, when the rotating shaft 9 rotates, it not only drives the spiral sludge removal mechanism, but also drives the bushing 6 and the transmission gear 8 to rotate synchronously through the meshing of the output driven gear 2 and the input driving gear 1. Through the meshing of the transmission gear 8 with the input gear on the input shaft of the traveling mechanism, the traveling mechanism is driven to operate, so that the traveling mechanism and the spiral sludge removal mechanism operate simultaneously. At this time, while the automatic sludge removal device moves at the bottom of the pool, the spiral sludge removal mechanism crushes the sludge at the bottom of the pool.

[0033] (2) Power cut-off state (separation): When the automatic sludge removal device reaches its destination or encounters an abnormally thick or compacted layer of sludge, causing excessive resistance to the tracks or even preventing it from moving forward, the operator sends a command to the reversing valve at the upper end of the linear drive structure 4 via the remote control system. The command signal controls the reversing valve to operate, causing the piston rod of the linear drive structure 4 to extend under the action of hydraulic oil. The linear drive structure 4 pushes the release mechanism 3 to swing. While swinging, the release mechanism 3 pushes the output driven gear 2 to move on the bushing 6. At this time, the return spring 5 is compressed, and the output driven gear 2 on the bushing 6 gradually moves away from the input drive gear 1 on the rotating shaft 9, causing the input drive gear 1 to separate from the output driven gear 2. At this time, when the rotating shaft 9 rotates, it drives the spiral sludge removal mechanism, and the input drive gear 1 rotates synchronously with the rotating shaft 9. However, when the rotating shaft 9 rotates, it cannot drive the output driven gear 2, bushing 6, and transmission gear 8 to rotate synchronously, making the traveling mechanism unable to operate, and the automatic sludge removal device cannot move forward in the pool bottom.

[0034] At this time, since only the spiral sludge-removing mechanism is operating, it can maintain full power operation and continue to break up the thick layer of sludge below. Meanwhile, the suction mechanism (submersible pump) on the automatic sludge removal device also continues to work, sucking away the broken and liquefied sludge.

[0035] (3) Restore power transmission state (re-engage): The operator observes the automatic sludge removal device through the monitoring system. When the device needs to continue moving, or when the spiral sludge-removing mechanism has broken up and removed the thick layer of sludge obstructing its progress, significantly reducing the resistance along the path, the operator sends a command to the directional valve at the upper end of the linear drive structure 4 via the remote control system. The command signal controls the directional valve to operate, causing the piston rod of the linear drive structure 4 to retract under the action of hydraulic oil. The tripping mechanism 3 drives the output driven gear 2 to move towards the input driving gear 1 on the bushing 6, and with the elastic force of the return spring 5, the output driven gear 2 moves towards... When the input drive gear 1 approaches and engages with the output driven gear 2, the rotating shaft 9 not only drives the spiral sludge removal mechanism when it rotates, but also drives the bushing 6 and the transmission gear 8 to rotate synchronously through the meshing of the output driven gear 2 and the input drive gear 1. Through the meshing of the transmission gear 8 with the input gear on the input shaft of the traveling mechanism, the traveling mechanism is driven to operate, so that the traveling mechanism and the spiral sludge removal mechanism operate simultaneously. At this time, while the automatic sludge removal device is moving at the bottom of the pool, the spiral sludge removal mechanism is breaking up the sludge at the bottom of the pool.

[0036] In this invention, the reset spring 5 and the linear drive structure 4 work together to achieve independent, remote, and rapid on / off control of the driving power of the traveling mechanism (track) under a single power input (rotating shaft 9), while ensuring that the power of the spiral screed mechanism is continuous and uninterrupted, effectively solving the pain points in the prior art.

[0037] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present invention.
