Description

Technical Field

[0001] This invention relates to the field of sludge hopper cleaning technology, and in particular to an environmentally friendly cleaning mechanism and method for using filter press sludge hoppers. Background Technology

[0002] Automatic environmentally friendly filter presses are used in the environmental protection industry to process mixtures of sludge and sewage or wastewater. The sludge storage hopper, located below the sludge discharge port of the filter press, is a post-filtering treatment device for sludge. It is used to accumulate sludge cake and automatically unload and load sludge onto trucks for transport and further processing.

[0003] Sludge buildup and hardening on the inner wall of the sludge storage hopper, if not cleaned, will affect its capacity. Existing technology for cleaning sludge adhering to the inner wall of the sludge storage hopper can be found in patent application number "202411206016.8," which uses scraping and vibration for cleaning. However, in actual operation, the equipment disclosed in the prior art has many transmission structures, leading to a complex transmission process and a large space requirement. Furthermore, the cleaning moving component and its connected cleaning mechanism in the aforementioned structure obstruct the discharge of sludge from the filter press's sludge discharge port (sludge storage hopper feed), and their large size makes them difficult to store (if not stored, they occupy internal storage space in the sludge storage hopper). Therefore, cleaning the sludge storage hopper requires installing the cleaning moving component and its connected cleaning mechanism on the sludge storage hopper, adding installation (for cleaning the sludge storage hopper) and disassembly (for feeding the sludge storage hopper), resulting in a cumbersome and time-consuming cleaning process. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of complex transmission and separate loading and disassembly of cleaning moving components in the existing sludge storage hopper cleaning device, and to propose an environmentally friendly cleaning mechanism and method for the sludge storage hopper of a filter press.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An environmentally friendly cleaning mechanism and usage method for a filter press sludge storage hopper includes a sludge storage hopper. A slide seat is slidably mounted on the top of the side wall of the sludge storage hopper. A carrier frame is installed on the slide seat. A scraper mounting plate is provided inside the carrier frame. A scraper is installed on the scraper mounting plate. One end of the scraper mounting plate is rotatably connected to the carrier frame through a hinge shaft, and the other end rotates around the hinge shaft as the rotation center.

[0006] Preferably, the top of the side wall of the sludge storage hopper is provided with a sliding seat moving part, which is composed of a screw driven by a motor.

[0007] Preferably, the end of the carrier is provided with a mounting base, the mounting base is rotatable on the top of the slide, and the rotation is driven by a rotary motor disposed on the slide.

[0008] Preferably, the mounting base is in the shape of an inverted "mountain", and an angle adjustment motor and a rotating disk are provided inside the mounting base, respectively located in two slots of the mounting base. The rotating disk is rotated by the braking force of the angle adjustment motor. An adjustment protrusion is fixed to the outer wall of the rotating disk. The adjustment protrusion passes through the side wall of the mounting base and extends outward. A vertical sliding groove for sliding the adjustment protrusion is provided on the side wall of the scraper mounting plate.

[0009] Preferably, the scraper is triangular prism-shaped.

[0010] Preferably, the scraper is composed of a vertically arranged annular body and a scraper blade disposed on the outer wall of the annular body, and the annular body is driven to rotate by a drive motor mounted on the scraper mounting plate; The annular body has a telescopic vibrating protrusion at its center.

[0011] Preferably, the vibrating protrusion is driven by a vibrating motor.

[0012] Preferably, the vibrating protrusion and the scraper mounting plate are connected by a vibration spring.

[0013] Preferably, the screw is provided with connecting seats at both ends, and the connecting seats are driven to move linearly up and down by a vertical drive member set on the top of the sludge hopper.

[0014] Preferably, the carrier is provided with a connecting bar driven by a linear drive, and the connecting bar and the scraper mounting plate are connected by multiple adjusting rods; A sliding limiter is provided between the connecting strip and the carrier.

[0015] The beneficial effects of this invention are as follows: In this invention, a scraper is mounted on a scraper mounting plate and divided into three areas, A, B, and C, based on the shape of the inner wall of the sludge hopper. When in areas A and C, the scraper mounting plate rotates around a point near the bottom end of the sludge hopper to achieve cleaning of areas A and C. When in area B, scraping is achieved by the horizontal movement of the scraper mounting plate.

[0016] In summary, the method for cleaning the inner wall of the sludge hopper in this application only requires the rotation and horizontal movement of the scraper mounting plate, without a large number of transmission structures, which makes the cleaning device lightweight; at the same time, reducing the complexity of the transmission mechanism also reduces the failure rate.

[0017] In addition, in this application, the scraper mounting plate is installed on the carrier, and the carrier can be switched to a horizontal state along the top of the side wall of the sludge hopper. In this state, the cleaning component is stored in the top of the side wall of the sludge hopper, which does not affect the feeding and does not occupy the internal storage space of the sludge hopper. Furthermore, since it is in a stored state at the top of the side wall of the sludge hopper, it only needs to be put down during cleaning, without the need for installation and subsequent disassembly as in the prior art. This greatly reduces the preparation stage before using the cleaning mechanism, thereby reducing the cleaning time.

[0018] Finally, in this application, the scraper is a combination of a triangular prism or a ring and a scraper blade. When the scraper is a combination of a ring and a scraper blade, and is combined with the vibrating protrusions inside the ring, the scraping process is accompanied by vibration, which has the advantages of high cleaning strength and good cleaning effect.

[0021] Reference Figures 1-6 The filter press sludge storage hopper environmental cleaning mechanism includes a sludge storage hopper 1, which is conventionally a funnel-shaped structure with four sides, a large opening at the top for feeding, and a small opening at the bottom for discharging. The sludge adheres to the inner walls of the four sides of the sludge storage hopper 1.

[0022] Based on the existing sludge hopper structure, this embodiment designs a structure that is easy to clean the sludge adhering to its inner wall. Specifically, the structure consists of a scraper 5 with an adjustable rotation angle, a scraper mounting plate 4 for mounting the scraper 5, a slide 2 that can slide along the top of the side wall of the sludge hopper 1, and a carrier 3 that connects the scraper mounting plate 4 and the slide 2, wherein the carrier 3 is arranged parallel to the inner wall surface of the sludge hopper 1.

[0023] It should be noted that the cleaning structure in this application is located on each side wall of the sludge storage hopper 1. Figure 1 Only one sidewall is shown in the image; the following sections will describe the situation from the perspective of the sidewall. Figure 1 For example, the structure of the cleaning facility will be explained separately.

[0024] Reference Figure 3 The inner wall of the sludge storage hopper 1 is divided into three areas from left to right: area A, area B, and area C.

[0025] During operation, the scraper 5 is first parallel to an inclined surface of the inner wall of the sludge hopper 1. Then, the scraper 5 rotates until it is vertical. During the rotation, the sludge on one side of the inner wall of the sludge hopper 1 is scraped off, completing the scraping of area A. Next, the slide 2 slides horizontally along the top of the side wall of the sludge hopper 1, and the scraper 5 scrapes off the sludge on the rectangular surface in the middle of the inner wall of the sludge hopper 1, completing the scraping of area B. When scraping off the sludge on the other side of the inner wall of the sludge hopper 1, the sludge hopper 1 is rotated until it is parallel to the other end. During the rotation, the sludge on the other side is scraped off, completing the scraping of area C.

[0026] It should be added that: 1. The sludge at the corners of the two inner walls of the sludge hopper 1 can be washed with a flushing head; 2. Within the range of the rotation angle of the scraper 5 (in area A or area C), the horizontal distance that the top of the scraper 5 moves is greater than or equal to the horizontal distance between the two endpoints on the same side of the sludge hopper 1, ensuring that the scraper 5 can scrape the two sides of the inner wall of the sludge hopper 1 (in areas A and C) during the rotation of the scraper 5 on both sides.

[0027] The above structure is used as follows: S1. The scraper mounting plate 4 rotates around the hinge shaft, and the scraper 5 scrapes off the sludge attached to both sides of the inner wall of the sludge storage hopper 1 (in area A or area C). S2. When the scraper mounting plate 4 is in a vertical position, drive the slide block 2 to move, causing the scraper mounting plate 4 to slide, and scrape off the sludge attached to the middle part (B area) of the inner wall of the sludge storage hopper 1 through the scraper 5.

[0028] In some embodiments, the slide 2 is driven by a slide moving member 6 located on the top of the side wall of the sludge hopper 1 and moves horizontally to scrape sludge in area B of the inner wall of the sludge hopper 1. The slide moving member 6 is composed of a screw 60 driven by a motor. Furthermore, the motor drives the screw 60 to rotate, and the screw 60 and the slide 2 are threadedly connected. Thus, as the screw 60 rotates, it drives the slide 2 to slide horizontally on the top of the sludge hopper 1, thereby driving the scraper mounting plate 4 installed inside it to move, so that the scraper 5 on the scraper mounting plate 4 scrapes the inner wall of the sludge hopper 1.

[0029] Furthermore, based on the carrier frame 3, it has the following effects: it facilitates the installation of the scraper mounting plate 4, and it moves synchronously with the slide 2. In addition, it can ensure that the scraper mounting plate 4 rotates, thereby scraping the surface sludge on both sides of the inner wall of the sludge storage hopper 1 (in areas A and C).

[0030] The carrier frame 3 is fixed on the slide block 2, and the fixing method can be conventional fixing methods such as welding or bolt connection. In addition, the bottom outer wall of the carrier frame 3 is provided with a hinge shaft, and the scraper mounting plate 4 rotates on the hinge shaft, so that the scraper mounting plate 4 is rotated around the hinge shaft. When the top of the scraper mounting plate 4 is subjected to the driving force of rotation, the scraper mounting plate 4 deflects around the hinge shaft. During this deflection process, the sludge on the surface of both sides of the inner wall of the sludge storage hopper 1 (in areas A and C) is scraped off.

[0031] It should be noted that the end of the hinge shaft is provided with a flange whose size is larger than the diameter of the hinge shaft, so as to prevent the scraper mounting plate 4 from detaching from the hinge shaft.

[0032] In some embodiments, based on the arrangement of the carrier 3, in order to facilitate the storage of the carrier 3 when the sludge on the inner wall of the sludge storage hopper 1 is not cleaned, it can be placed horizontally along the top of the side wall of the sludge storage hopper 1, so that the cleaning components can be easily stored when the cleaning device is not needed.

[0033] This storage method has the following advantages: Advantage 1: The cleaning component's carrier 3, scraper mounting plate 4, and scraper 5 installed on it are not located inside the sludge storage hopper 1 after being stored, which avoids the cleaning component being affected by the impact of sludge when falling and the sludge pressure when it is stationary, thus protecting the cleaning component.

[0034] Advantage 2: The overall structure of this cleaning component, including the carrier 3, scraper mounting plate 4, and scraper 5 mounted on it, is small in size and has a wide cleaning range. When combined and stored, it is placed horizontally along the top of the side wall of the mud storage hopper 1, so it can always be located on the mud storage hopper 1 without needing to be set up outside. When needed, it can be used automatically and quickly. Compared with the use of some other external cleaning components in the prior art, it has high mobilization efficiency and does not require mobilizing the moving parts of the external cleaning device.

[0035] Furthermore, to facilitate switching the state of the carrier 3, that is, switching back and forth between the vertical state and the horizontal state, specifically, the vertical state is the working state of the cleaning components, and the horizontal state is the storage state of the cleaning components. In some embodiments, the structure for driving the switching of the state of the carrier 3 is as follows: the end of the carrier 3 is provided with a mounting base 30, the mounting base 30 is rotated on the top of the slide 2, and is driven to rotate by a rotation motor 20 on the slide 2.

[0036] Furthermore, the bottom of the mounting base 30 is arc-shaped or has a disc-shaped structure. The bottom of the mounting base 30 rotates to the top of the slide 2, so the slide 2 can assist in supporting the mounting base 30. The switching process is as follows: the rotating motor 20 drives the mounting base 30 to rotate, thereby driving the carrier 3 to rotate 90°, switching back and forth between the vertical and horizontal states.

[0037] Reference Figure 2 , Figure 4 and Figure 5 This embodiment also discloses a drive structure for rotating the top of the scraper mounting plate 4. This structure is driven by an angle adjustment motor 300, which is a rotary motor in the prior art. Furthermore, based on the structural configuration of the mounting base 30, the slide 2, and the carrier 3, the structural configuration of the angle adjustment motor 300 driving the top of the scraper mounting plate 4 is as follows: The mounting base 30 is shaped like an inverted "mountain". An angle adjustment motor 300 and a rotating disk 301 are installed inside the mounting base 30, and are respectively located in the two slots of the inverted "mountain" shape of the mounting base 30. The rotating disk 301 is braked to rotate by the angle adjustment motor 300. That is, the angle adjustment motor 300 drives the rotating disk 301 to rotate, and drives the scraper mounting plate 4 to rotate through the transmission structure between the rotating disk 301 and the scraper mounting plate 4.

[0038] In some embodiments, the transmission structure can be configured as follows: an adjustment protrusion 3010 is fixed on the outer wall of the rotating disk 301, wherein the adjustment protrusion 3010 is eccentrically disposed on the outer wall of the rotating disk 301, the adjustment protrusion 3010 passes through the side wall of the mounting base 30 and extends outward (the mounting base 30 is provided with an arc-shaped sliding opening for adjusting the rotation of the protrusion 3010, for the adjustment protrusion 3010 to slide after passing through), and a vertical sliding groove 40 is provided on the side wall of the scraper mounting plate 4 for adjusting the sliding of the protrusion 3010, wherein the length of the vertical sliding groove 40 is at least the horizontal distance between the two ends of the arc-shaped sliding opening, preferably, it is also greater than the horizontal distance between the two ends on the same side of the sludge hopper 1, so as to ensure that when the scraper 5 rotates in the A and C areas of the clean surface of the sludge hopper 1, it can completely cover the entire area.

[0039] Furthermore, after the eccentric adjustment protrusion 3010 rotates with the rotating disk 301, it abuts against the inner wall of the vertical slide groove 40. After the inner wall of the vertical slide groove 40 is subjected to force, it drives the scraper mounting plate 4 to rotate around the hinge axis as the rotation center.

[0040] It should be added that: considering that after the rotating disk 301 is set, the radius of the arc-shaped sliding opening needs to be at least the horizontal distance between the two endpoints on the same side of the sludge hopper 1. Otherwise, the scraper mounting plate 4 cannot completely cover the A and C areas of the clean surface of the sludge hopper 1 after rotation. This situation results in a larger size of the mounting base 30, that is, it needs to meet the setting of the arc-shaped sliding opening, which makes the volume of the slide 2 and the mounting base 30 larger, increasing the space occupied and causing inconvenience in use. Therefore, the adjustment protrusion 3010 driven by the rotating disk 301 disclosed above can only adapt to the small angle rotation of the scraper mounting plate 4, that is, adapt to the sludge hopper 1 with a small angle between the inclined side of the inner wall of one side of the sludge hopper 1 and the vertical direction.

[0041] In some other implementation methods, refer to Figure 5 By replacing the rotating disk 301 with a connecting rod, the size of the slide 2 and mounting base 30 can be reduced, while allowing the scraper mounting plate 4 to rotate over a wide range. Specifically, one end of the connecting rod is fixed to the output end of the angle adjustment motor 300, and the adjustment protrusion 3010 is fixed to the other end of the connecting rod. The length of the connecting rod is at least the horizontal distance between the two endpoints on the same side of the sludge hopper 1, ensuring that the scraper 5 completely covers areas A and C of the clean surface of the sludge hopper 1 after rotation. That is, by adjusting the length of the connecting rod, it can be adapted to different angles of the inner wall slope of the sludge hopper 1. To facilitate the setting of the connecting rod and avoid it affecting the contact between the scraper 5 and the inner wall of the sludge hopper 1, the connecting rod can be set between the scraper mounting plate 4 and the carrier 3. The vertical sliding groove 40 that cooperates with the adjustment protrusion 3010 is located on the side wall of the scraper mounting plate 4 opposite to the carrier 3.

[0042] After the connecting rod is set, since the maximum rotation angle required when switching the scraper mounting plate 4 is 90°, the connecting rod and the carrier 3 are parallel when the connecting rod is in the scraping and storage state in area B. That is, the angle adjustment motor 300 drives the connecting rod to make it vertical. In this way, the connecting rod will not protrude from the carrier 3, avoiding space occupation. After the connecting rod is set, its working range is always located below the mounting base 30 and is not affected by the shape of the mounting base 30. Therefore, the setting volume of the slide 2 and the mounting base 30 is not affected. Thus, the volume of the slide 2 and the mounting base 30 is not affected at all, and only installation space needs to be provided for the angle adjustment motor 300.

[0043] In addition, in some embodiments, the connecting rod is adjustable in length to accommodate different zones A and C on both sides of the sludge hopper 1.

[0044] Reference Figure 2 and Figure 4 In this embodiment, the scraper 5 is preferably triangular prism in shape, that is, the sludge on the inner wall of the sludge storage hopper 1 is scraped off by the contact between the corners of the end of the triangular prism and the inner wall of the sludge storage hopper 1.

[0045] In some other embodiments, an additional driving force, namely a scraping component, is provided to enhance the scraping effect. In this embodiment, an annular body 50 with a scraper 51 driven by a drive motor is used as an example.

[0046] Among them, reference Figure 6 The scraper 5 consists of a vertically arranged annular body 50 and a scraper 51 disposed on the outer wall of the annular body 50. The annular body 50 is driven to rotate by a drive motor mounted on the scraper mounting plate 4. When the scraper 51 contacts the inner wall of the sludge storage hopper 1, the drive motor drives the annular body 50 to rotate, thereby driving the scraper 51 to rotate. Under the driving force of the drive motor, the sludge attached to the inner wall of the sludge storage hopper 1 is scraped off, which can more thoroughly clean the sludge attached to the inner wall of the sludge storage hopper 1.

[0047] The drive motor can drive the ring body 50 to rotate through a gear transmission assembly or a disc-shaped connector. Furthermore, the gear transmission assembly consists of a driving gear and a driven gear. The driving gear is fixed to the output end of the drive motor, and the driven gear is fixed to the outer wall of the ring body 50. When the disc-shaped connector is a disc-shaped structure, it is directly driven by the drive motor, and the ring body 50 is fixed to the outer wall of the disc.

[0048] Additionally, refer to Figure 6 This embodiment is based on the structure of the annular body 50, and is further combined with the vibration protrusion 7 located at the center of the annular body 50. The vibration protrusion 7 is movable at the center of the annular body 50. When the scraper mounting plate 4 approaches the inner wall of the sludge storage hopper 1, the vibration protrusion 7 first abuts against the inner wall of the sludge storage hopper 1. At the same time, the vibration of the vibration protrusion 7 first vibrates and disloosens the sludge near the vibration protrusion 7, and the range spreads outward from the vibration protrusion 7 as the center. This just matches the spatial layout of the annular body 50 around the vibration protrusion 7, making it easy for the annular body 50 to fit against the inner wall of the sludge storage hopper 1. At the same time, the vibration protrusion 7 loosens the sludge attached to the inner wall of the sludge storage hopper 1 in advance, which helps the scraper 51 to rotate and clean further. In addition, this method combines the vibration source and the annular body 50, and the combination of the two is more compact. They can cooperate with each other in terms of structure and effect, and the cleaning is more thorough.

[0049] Additionally, refer to Figure 6 The driving source for the vibrating protrusion 7 can be a vibrating motor or a vibrating spring 8, preferably a vibrating motor. When it is a vibrating spring 8, the vibrating spring 8 is positioned between the vibrating protrusion 7 and the scraper mounting plate 4. When it is a vibrating motor, there are two possible configurations: Method 1: Each vibrating protrusion 7 corresponds to a vibrating motor.

[0050] Method 2: Multiple vibrating protrusions 7 are connected to the same connector, which can be a plate or strip-shaped transmission component. There is one vibrating motor, whose output end is connected to the connector, and the vibration is transmitted to multiple vibrating protrusions 7 through the connection.

[0051] This embodiment also discloses a transmission structure for driving the scraper mounting plate 4 to move toward the inner wall of the mud storage hopper 1, referring to... Figure 6 This transmission structure controls the distance between the scraper blade 5 and the inner wall of the sludge hopper 1. The relationship between the distance between the scraper blade 5 and the inner wall of the sludge hopper 1 and the working mode is as follows: Contact 1: When the scraper 5 and the sludge hopper 1 are in contact, the scraper 5 cleans the sludge attached to the inner wall of the sludge hopper 1 as the scraper mounting plate 4 moves. Contact 2: When the distance between the scraper 5 and the sludge hopper 1 changes continuously, the sludge adhering to the inner wall of the sludge hopper 1 is loosened by vibration using the vibrating protrusion 7, which prepares for the subsequent cleaning of the scraper 5 and the sludge hopper 1. In practice, whenever the scraper mounting plate 4 moves, the sludge adhering to the inner wall of the sludge hopper 1 can be loosened by vibration using the vibrating protrusion 7; or, for areas of difficult-to-clean sludge adhering to the inner wall of the sludge hopper 1, the scraper 5 can be adjusted to the corresponding position, and the sludge can be loosened by vibration using the vibrating protrusion 7, and then scraped off by the scraper 51.

[0052] It should be added that: In the second connection, when the vibrating protrusion 7 is driven by a vibrating motor, a distance buffer spring can be added between the vibrating protrusion 7 and the output end of the vibrating motor to prevent the vibrating protrusion 7 from being unable to adapt to the distance between itself and the inner wall of the sludge hopper 1 due to changes in distance, thus avoiding damage to the inner wall of the sludge hopper 1 caused by the vibrating protrusion 7. Additionally, when the vibrating protrusion 7 is driven by the vibrating spring 8, the working method is as follows: after the scraper mounting plate 4 moves towards the inner wall of the sludge hopper 1, the vibrating protrusion 7 comes into contact with the inner wall of the sludge hopper 1, and the vibrating spring 8 is compressed. Subsequently, the scraper mounting plate 4 moves rapidly outward. At this time, the compressed vibrating spring 8 vibrates continuously. Then, the scraper mounting plate 4 is slowly moved closer to the inner wall of the sludge hopper 1. Through the elasticity of the vibrating spring 8, the vibrating protrusion 7 is driven to vibrate and loosen the sludge attached to the inner wall of the sludge hopper 1.

[0053] In some embodiments, the transmission structure is composed as follows: Reference Figure 6 The carrier 3 is equipped with a connecting bar 31 driven by a linear drive component, which can be any drive component capable of linear movement, such as a cylinder or a lead screw. The connecting bar 31 and the scraper mounting plate 4 are connected by multiple adjusting rods 32, with both ends of the adjusting rods 32 rotatably connected to the connecting bar 31 and the scraper mounting plate 4, respectively. Specifically, by rotating the shaft, the adjusting rods 32 are initially tilted. After the connecting bar 31 moves linearly, the distance between the connecting bar 31 and the scraper mounting plate 4 is changed by adjusting the adjusting rods 32. Since the connecting bar 31 is attached to the outer wall of the carrier 3, the scraper mounting plate 4 can only move outward, thus approaching the inner wall of the sludge storage hopper 1.

[0054] A sliding limit component is provided between the connecting strip 31 and the carrier 3. The main function of the sliding component is to ensure that the connecting strip 31 is in contact with the inner wall of the carrier 3, while it can rotate with the scraper mounting plate 4 around the hinge axis. The specific configuration is as follows: The connecting strip 31 is provided with a slide rail seat 33 on its outside. The slide rail seat 33 and the scraper mounting plate 4 are connected by multiple telescopic rods 35 to ensure that the scraper mounting plate 4 can only slide horizontally relative to the slide rail seat 33. In addition, the connecting strip 31 slides inside the slide rail seat 33, and the outer wall of the slide rail seat 33 is provided with multiple limiting protrusions 34. The carrier 3 is provided with an arc-shaped groove corresponding to the limiting protrusions 34. The arc-shaped groove is rotated around the hinge axis. Furthermore, the cross-section of the limiting protrusions 34 is T-shaped or a block structure with flanges. The uneven surface of the limiting protrusions 34 is avoided, and the limiting protrusions 34 and the arc-shaped groove are prevented from separating.

[0055] In some embodiments, to ensure the stability of the connecting strip 31, the connecting strip 31 can be rotatably sleeved on the outer wall of the hinge shaft without providing the limiting protrusion 34.

[0056] Considering that the space below the mud storage hopper 1 is small and hinders the rotation of the carrier 3 when it rotates from a vertical to a horizontal state, this embodiment discloses a structure to avoid the carrier 3 being obstructed from rotating. The structure is as follows: the two ends of the screw 60 are provided with connecting seats 61. The connecting seats 61 are driven to move linearly up and down by a vertical drive member set on the top of the mud storage hopper 1. The vertical drive member can be any structure that can linearly drive the connecting seats 61 to move, such as a cylinder or a lead screw. The screw 60 is raised by the vertical drive member, causing the carrier 3 in the vertical state to move upward synchronously. In this way, when the carrier 3 rotates, the space at its bottom becomes larger (because the inner wall of the mud storage hopper 1 has a trapezoidal structure, after the carrier 3 moves upward, the horizontal distance between its bottom end and the inclined side of the mud storage hopper 1 becomes larger, resulting in a larger space for the carrier 3 to move when rotating inside the mud storage hopper 1), which makes it easier to store the carrier 3 after it rotates.

[0057] Finally, refer to Figure 1 To prevent damage to the slide block 2, carrier frame 3, scraper mounting plate 4 and scraper 5 after storage, an openable or closable protective cover structure 9 can be installed on the top of the side wall of the mud storage hopper 1. This protective cover structure 9 can be any cover structure and has an isolation effect.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
