[0001] This invention relates to the field of construction engineering technology, and in particular to a cleaning device and method for using construction engineering material conveying equipment. Background Technology

[0002] In the construction industry, when material conveying equipment transports sticky materials such as wet concrete and mortar, the materials are very easy to adhere to and remain on the surface of the conveyor belt. If they are not cleaned in time, these materials will accumulate over a long period of time or fall into the inside of the conveying equipment, which will affect the conveying accuracy.

[0003] Currently, the removal of such residues mainly relies on manual shutdown operations, which is not only inefficient and severely affects the continuity of material conveying, but also physically demanding and poses safety hazards.

[0045] The technical solutions of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0046] In the description of the embodiments of this invention, it should be understood that the terms "top," "bottom," etc., indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention through specific circumstances.

[0047] Reference Appendix Figure 1-12 This invention provides a cleaning device for a construction material conveying equipment, which is located below the construction material conveying equipment (e.g., a material conveyor belt 11). Specifically, it includes the following structure: a collection box 1, a scraping mechanism 2, and a cleaning mechanism 3. The top end of the scraping mechanism 2 contacts the lower surface of the material conveyor belt 11. The top end of the collection box 1 is open and located below the scraping mechanism 2, and can receive the debris scraped off by the scraping mechanism 2. The side or bottom end of the collection box 1 can be opened and closed. The cleaning mechanism 3 is located on the collection box 1 and can remove the debris collected by the collection box 1 from its openable side or bottom end.

[0048] More specifically: see attached document Figure 6The scraping mechanism 2 includes a scraper 2.1, a movable frame 2.2, a first stiffening spring 2.3, and a support box 2.4. The scraper 2.1 is located at the top of the movable frame 2.2, and the other end of the movable frame 2.2 slides through the support box 2.4, connecting to the first stiffening spring 2.3 located inside the support box 2.4. This structure constitutes an adaptive floating pressurization system. The first stiffening spring 2.3 provides continuous and constant upward pressure to the scraper 2.1, enabling the scraper 2.1 to not only closely adhere to the bottom surface of the material conveyor belt 11 to remove residual material, but also to automatically float up and down when the material conveyor belt 11 jumps or the scraper 2.1 wears, avoiding hard impacts, protecting the conveyor belt, and compensating for wear, thereby achieving stable and continuous online cleaning.

[0049] To provide suitable and sufficient stiffening force to the scraper 2.1, this embodiment provides multiple sets of first stiffening springs 2.3 in the inner cavity of the support box 2.4. The selection of the first stiffening springs 2.3 can be made by those skilled in the art according to actual needs (such as material viscosity) to adjust the optimal cleaning pressure.

[0050] Reference Appendix Figure 12 The movable frame 2.2 includes a support plate 2.21 and multiple movable blocks 2.22. The bottom end of the support plate 2.21 is connected to multiple first stiffening springs 2.3, and the top end is connected to multiple movable blocks 2.22. The top end of each movable block 2.22 is connected to a scraper 2.1. Furthermore, the outer contour of the support plate 2.21 is adapted to the inner contour of the support box 2.4, that is, the outer edge of the support plate 2.21 slides against the inner wall of the support box 2.4. The top end of the support box 2.4 is provided with through holes 2.41, which are the same number and position as the movable blocks 2.22. The outer contour of each movable block 2.22 is adapted to the inner contour of the through holes 2.41, that is, the outer edge of each movable block 2.22 slides against the inner wall of the through holes 2.41. This double sliding fit design ensures the stability and synchronicity of the vertical movement of the movable frame 2.2 under the drive of the first stiffening springs 2.3, prevents the scraper 2.1 from tilting, and enables the scraper 2.1 to reliably adhere to the surface of the conveyor belt.

[0051] In practice, the support box 2.4 can be fixed to the base frame of the construction material conveying equipment, such as the bottom support leg of the material conveyor belt 11. If the support box 2.4 is directly connected to the base frame of the construction material conveying equipment due to space limitations or poor scraping and cleaning position, the operating effect and quality of the device will not be high. An L-shaped connecting arm 2.5 can be set on the side of the support box 2.4. One end of the L-shaped connecting arm 2.5 is connected to the support box 2.4, and the other end is connected to the base frame of the construction material conveying equipment. The distance between the support box 2.4 and the base frame of the construction material conveying equipment is increased by using the L-shaped connecting arm 2.5 to obtain better installation conditions and scraping and cleaning position.

[0052] In some preferred embodiments, the movable frame 2.2 and the scraper 2.1 are connected by a first mounting groove 2.6, a first mounting block 2.7, and a first clamping member 2.8. The first mounting groove 2.6 is an inverted T-shaped groove with its opening facing upwards, and its long end is open to allow the first mounting block 2.7 to move into the first mounting groove 2.6 from its long end. The first mounting block 2.7 is an inverted T-shaped block that fits the shape of the first mounting groove 2.6. The first mounting block 2.7 is detachably disposed within the first mounting groove 2.6, and its top end extends out of the first mounting groove 2.6 to connect with the scraper 2.1. The first mounting plate 2.6 is provided with a first through hole 2.61 and a first slot 2.71 corresponding to the position. The first locking piece 2.8 is movably disposed outside the first mounting groove 2.6 and is detachably connected to the first through hole 2.61 and the first slot 2.71. When the first locking piece 2.8 is connected to the first through hole 2.61 and the first slot 2.71, the first mounting groove 2.6 and the first mounting block 2.7 are firmly connected. When the first locking piece 2.8 is separated from the first slot 2.71, the first mounting block 2.7 can slide relative to the first mounting groove 2.6, so that the long end of the first mounting groove 2.6 can be removed. This structural solution is conducive to the installation, removal and replacement of the scraper 2.1, so that the device maintains a better impurity removal effect.

[0053] In practice, the scraper 2.1 can be directly connected to the top of the first mounting block 2.7, or it can be connected to the first mounting block 2.7 through several separately arranged connecting blocks 2.9.

[0054] Reference Appendix Figure 7 , 9 -10, a first fixing box 2.10 is provided outside the first mounting groove 2.6. The first fixing box 2.10 corresponds to the position of the first through hole 2.61 and is connected to the first slot 2.71 through the first through hole 2.61. The first locking member 2.8 includes a first screw 2.81, a first limiting plate 2.82 and a first locking block 2.83. One end of the first screw 2.81 passes through the first fixing box 2.10 and is threaded to it. The other end is rotatably connected to the first limiting plate 2.82 located inside the first fixing box 2.10. The first limiting plate 2.82 slides against the inner wall of the first fixing box 2.10. Its other end is connected to the first locking block 2.83. The first locking block 2.83 can slide along the first through hole 2.61 and lock into the first slot 2.71. When the first screw 2.81 is rotated, the length of the first screw 2.81 within the first fixed box 2.10 changes, thereby causing the first limiting plate 2.82 to move within the first fixed box 2.10, which in turn causes the first locking block 2.83 to engage or disengage from the first locking slot 2.71.

[0055] For ease of operation, a handle 2.84 can be provided on the end of the first screw 2.81 that extends out of the first fixing box 2.10.

[0056] Reference Appendix Figure 5 and 8 In this embodiment, the collection box 1 is a rectangular box with an open top and an openable side wall 1.1. The cleaning mechanism 3 includes a push plate 3.1 disposed opposite to the openable side wall 1.1. The push plate 3.1 is connected to the collection box 1 through a transverse drive assembly 3.2 and can be driven by the transverse drive assembly 3.2 to move toward the openable side wall 1.1 to push the debris in the collection box 1 out of the box from the openable side wall 1.1.

[0057] Specifically, the transverse drive assembly 3.2 includes a servo motor 3.21, a second screw 3.22, and a transmission sleeve 3.23. The second screw 3.22 is perpendicular to the surface of the push plate 3.1 and rotatably connected to the collection box 1. The servo motor 3.21 is fixed to the collection box 1, and its actuator is connected to the second screw 3.22 to drive the second screw 3.22 to rotate. The transmission sleeve 3.23 is sleeved on the second screw 3.22, with its inner wall threaded to the second screw 3.22 and its outer wall slidably fitted to the collection box 1. The push plate 3.1 is fixedly connected to the outer wall of the transmission sleeve 3.23. Using the above structure, when the servo motor 3.21 drives the second screw 3.22 to rotate, the transmission sleeve 3.23 can move along the axial direction of the second screw 3.22, thereby driving the push plate 3.1 to move and push the debris in the collection box 1.

[0058] It is worth noting that, in order to ensure the transmission effectiveness of the first screw 2.81 and the second screw 3.22, the first limiting plate 2.82 and the inner wall of the first fixed box 2.10 have at least one (or more, for example, the outer contour of the first limiting plate 2.82 is set to a cubic shape) flat contact surface, and the transmission screw sleeve 3.23 and the inner wall of the collection box 1 have at least one (or more, for example, the outer contour of the transmission screw sleeve 3.23 is set to a cubic shape) flat contact surface. Thus, under the limiting effect of the flat contact surface, the first limiting plate 2.82 and the transmission screw sleeve 3.23 can move but cannot rotate.

[0059] To ensure smooth movement of the push plate 3.1, this embodiment includes two sets of second screws 3.22, two sets of transmission sleeves 3.23, two sets of transmission worm gears 3.24, and one double-headed worm gear 3.25. The two sets of second screws 3.22 are correspondingly arranged and distributed along the width of the push plate 3.1. The two sets of transmission sleeves 3.23 are respectively fitted onto different second screws 3.22 and connected to different positions on the push plate 3.1, thereby providing uniform moving power to the push plate 3.1. The two sets of transmission worm gears 3.24 are respectively located on the same side end of the two sets of second screws 3.22 and respectively mesh with different helical teeth on the double-headed worm gear 3.25. The double-headed worm gear 3.25 is rotatably connected to the collection box 1, and one axial end is fixedly connected to the execution end of the servo motor 3.21.

[0060] Using the above technical solution, when the servo motor 3.21 drives the double-headed worm gear 3.25 to rotate, the two sets of second screws 3.22 rotate synchronously through the transmission action of the transmission worm wheel 3.24, thereby causing the two sets of transmission screw sleeves 3.23 to move synchronously, and thus driving the push plate 3.1 to move smoothly in the collection box 1.

[0061] The selection and assembly (including the direction of the threads and helical teeth) of the second screw 3.22, transmission screw sleeve 3.23, transmission worm gear 3.24, and double-headed worm 3.25 can be designed by those skilled in the art based on common knowledge and actual needs, and no more specific limitations are made here.

[0062] To ensure stable installation and smooth operation of the above structures, corresponding mounting brackets can be installed on the inner and outer walls of the collection box 1. For example, a first mounting bracket 3.3 can be installed on the inner wall of the collection box 1. The first mounting bracket 3.3 is perpendicular to the surface of the push plate 3.1, that is, the first mounting bracket 3.3 extends in the same direction as the second screw 3.22. The second screw 3.22 is located inside the first mounting bracket 3.3, and its two ends are rotatably connected to the collection box 1. The transmission sleeve 3.23 is located inside the first mounting bracket 3.3 and slides in contact with the inner wall of the first mounting bracket 3.3. Alternatively, a second mounting bracket 3.4 can be installed on the outer wall of the collection box 1. The second mounting bracket 3.4 is parallel to the surface of the push plate 3.1, that is, the second mounting bracket 3.4 is perpendicular to the second screw 3.22. The double-headed worm gear 3.25 is perpendicular to the second screw 3.22 and arranged inside the second mounting bracket 3.4. The double-headed worm gear 3.25 is rotatably connected to the second mounting bracket 3.4. The transmission worm wheel 3.24 is located inside the second mounting bracket 3.4 and meshes with the double-headed worm gear 3.25. In addition, a third mounting bracket 3.5 can be set on the outside of the second mounting bracket 3.4 to fix the servo motor 3.21, so that the output shaft of the servo motor 3.21 is stably and precisely connected to the double-headed worm gear 3.25.

[0063] The selection and assembly of the first mounting bracket 3.3, the second mounting bracket 3.4, and the third mounting bracket 3.5 mentioned above can be designed by those skilled in the art based on common knowledge and actual needs, and no more specific limitations are made here.

[0064] In some preferred embodiments, the collection box 1 and the openable side panel are connected by a second mounting groove 4, a second mounting block 5, and a second fastener 6. The second mounting groove 4 is a T-shaped groove with its opening facing the inside of the collection box 1, and its long end is open to allow the second mounting block 5 to move into the second mounting groove 4 from its long end. The second mounting block 5 is a T-shaped block that is adapted to the shape of the second mounting groove 4. The second mounting block 5 is detachably disposed in the second mounting groove 4, and its side end extends out of the second mounting groove 4 to connect to the openable side panel. The second mounting groove 4 and the second mounting block 5 are respectively provided with corresponding second through holes 4. 1. The second slot 5.1 and the second locking piece 6 are movably disposed outside the second mounting groove 4 and are detachably connected to the second through hole 4.1 and the second slot 5.1. When the second locking piece 6 is connected to the second through hole 4.1 and the second slot 5.1, the second mounting groove 4 and the second mounting block 5 are securely connected. When the second locking piece 6 is separated from the second slot 5.1, the second mounting block 5 can slide relative to the second mounting groove 4, thereby removing the long end of the second mounting groove 4, so that the openable side plate can be removed from the side end of the collection box 1, exposing a channel at the side end of the collection box 1. The push plate 3.1 can push the debris in the collection box 1 out of the box through this channel.

[0065] Reference Appendix Figure 2 , 4 11. A second fixing box 8 is provided outside the second mounting slot 4. The second fixing box 8 corresponds to the position of the second through hole 4.1 and is connected to the second slot 5.1 through the second through hole 4.1. The second locking member 6 includes a sliding rod 6.1, a second limiting plate 6.2, a second locking block 6.3 and a second stiffening spring 7. One end of the sliding rod 6.1 slides through the second fixing box 8, and the other end is fixedly connected to the second limiting plate 6.2 located inside the second fixing box 8. The second limiting plate 6.2 slides and engages with the inner wall of the second fixing box 8. Its other end is connected to the second locking block 6.3. The second locking block 6.3 can slide along the second through hole 4.1 and engage with the second slot 5.1. The second stiffening spring 7 is sleeved on the sliding rod 6.1, and its two ends respectively contact the inner wall of the second fixing box 8 and the second limiting plate 6.2. When the slide bar 6.1 is pulled, the length of the slide bar 6.1 within the second fixed box 8 changes, thereby causing the second limiting plate 6.2 to move within the second fixed box 8, which in turn causes the second locking block 6.3 to separate from the second locking groove 5.1. When released (based on the corresponding states of the second through hole 4.1 and the second locking groove 5.1), under the action of the second stiffening spring 7, the slide bar 6.1, the second limiting plate 6.2, and the second locking block 6.3 can move toward the second locking groove 5.1, thereby allowing the second locking block 6.3 to insert into the second locking groove 5.1.

[0066] In addition, see attached document Figure 11A rotary handle 9 is provided at the end of the slide rod 6.1 extending out of the second fixing box 8. The rotary handle 9 is rotatably connected to the slide rod 6.1. A retaining bracket 10 is provided outside the second fixing box 8 for engaging the rotary handle 9. The rotary handle 9 is used as follows: when it is necessary to separate the second locking block 6.3 from the second locking groove 5.1, the rotary handle 9 is pulled along the axial direction of the slide rod 6.1, which can move the slide rod 6.1. When the rotary handle 9 moves to the side edge of the retaining bracket 10, the rotary handle 9 is rotated to change the direction of the rotary handle 9, so that the rotary handle 9 is engaged on the retaining bracket 10, thus fixing the position of the slide rod 6.1.

[0067] The shapes of the rotary handle 9 and the latch bracket 10 can be configured according to actual usage requirements, such as those shown in this embodiment. Figure 11 In the example shown, the purpose of setting up the aforementioned rotary handle 9 and clamp bracket 10 is mainly as follows: the area of ​​the openable side panel is relatively large, and it generally needs to be fixed at multiple points. Therefore, multiple sets of the combination of the second mounting slot 4, the second mounting block 5, and the second clamp 6 need to be configured. During installation and removal, the rotary handle 9 and clamp bracket 10 are used to temporarily fix one or more sets of the second clamp 6, which helps to improve the overall installation and removal efficiency of the openable side panel. In addition, due to the presence of the rotary handle 9, the slide bar 6.1 can be prevented from extending too much into the second fixing box 8, making it difficult to perform the next pull-out operation.

[0068] The above-mentioned cleaning device is used as follows: the cleaning mechanism 3 and the collection box 1 are assembled and secured. The scraping mechanism 2 and the collection box 1 are arranged vertically in a suitable position below the material conveyor belt 11, so that the scraper 2.1 in the scraping mechanism 2 contacts the lower surface of the material conveyor belt 11. The material conveyor belt 11 is started and put into normal operation. During this period, the scraping mechanism 2 continuously scrapes the material conveyor belt 11 to prevent the material from sticking. After being scraped, the material falls into the collection box 1 under its own gravity. After the collection box 1 has collected a certain amount of debris, the material conveyor belt 11 is turned off, the slide bar 6.1 is pulled out to separate the second locking block 6.3 from the second locking groove 5.1, and then the second mounting block 5 is moved out of the second mounting groove 4 so that the openable side plate is removed. The servo motor 3.21 is started, and under the action of the double-headed worm gear 3.25, the transmission worm wheel 3.24, the second screw 3.22, and the transmission screw sleeve 3.23, the push plate 3.1 moves in the collection box 1, thereby pushing the debris away from the openable side plate.

[0069] If the scraper 2.1 is found to be damaged and the scraping effect is reduced during the use of the device, the material conveyor belt 11 can be shut down, the first screw 2.81 can be screwed to separate the first locking block 2.83 from the first locking groove 2.71, and then the first mounting block 2.7 can be removed from the first mounting groove 2.6 to remove the old scraper 2.1 and replace it with a new scraper 2.1.

[0070] Compared with the prior art, the present invention has at least the following beneficial effects: By setting up an adaptive floating pressure scraping mechanism 2 composed of a scraper 2.1, a movable frame 2.2, a first stiffening spring 2.3, and a support box 2.4, the scraper 2.1 is dynamically attached to the surface of the material conveyor belt 11 under appropriate pressure, effectively removing the adhered material and avoiding damage to the conveying equipment. Simultaneously, the collection box 1, in conjunction with a side plate that can be quickly opened and closed and a push-plate type cleaning mechanism 3.1 driven by a servo motor 3.21, achieves automatic collection and efficient removal of debris, significantly reducing manual intervention and maintenance downtime. This device significantly improves the continuity of material conveying, operational safety, and overall operating efficiency while ensuring thorough cleaning and equipment safety.

[0071] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
