Description

Technical Field

[0001] This invention relates to the technical field of building construction formwork, specifically a cleaning device for building construction formwork. Background Technology

[0002] Construction formwork is the mold and support used for pouring concrete during construction. As a temporary support structure, it provides necessary support for the concrete during the pouring process, ensuring that the concrete maintains the correct shape and size as designed in advance. Depending on the different construction needs of the building project, there are various types of construction formwork used, such as plywood formwork, combined steel formwork, and combined aluminum formwork.

[0003] After use, building formwork usually has solidified concrete residue or other debris stuck to it. If the surface of the formwork is not cleaned in time, it can easily cause corrosion and damage, affecting the reuse of the formwork and the quality of subsequent concrete pouring.

[0004] A search of the invention patent with patent number CN108086681B reveals a surface cleaning device for building formwork, including an operating table, a drive device, a first cleaning device, and a second cleaning device. The first and second cleaning devices can perform preliminary cleaning on the other side of the formwork, making the brush cleaning the formwork more effective. The tapping device can first tap off the impurities on the formwork, making the brush clean the formwork surface more effectively, resulting in a cleaner finish and achieving excellent cleaning results with low labor intensity.

[0005] The construction formwork cleaning devices used in the aforementioned patents and existing technologies still have certain drawbacks, such as:

[0006] 1. Existing methods for cleaning building formwork mostly rely on manual cleaning, where concrete residue on the formwork is scraped off by hand. However, the efficiency of manual cleaning is far lower than that of automated mechanical cleaning. Furthermore, manual cleaning is time-consuming and labor-intensive, increasing the workload of cleaning personnel and failing to achieve the goal of convenient and easy cleaning.

[0007] 2. When concrete adheres and solidifies on the formwork, stubborn concrete debris may remain. However, the formwork cleaning method in the above patent relies solely on the vibration of the hammering device and the rotation of the brush. This method may not be able to remove or clean the stubborn concrete debris completely, thus affecting the quality of formwork cleaning.

[0008] Therefore, we propose a cleaning device for building construction formwork to solve the problems mentioned above. Summary of the Invention

[0009] The purpose of this invention is to provide a cleaning device for building construction formwork, which solves the problems mentioned in the background art, such as the time-consuming and laborious manual cleaning operation, which fails to achieve the purpose of convenient and easy cleaning, and the problem that stubborn concrete debris residue cannot be cleaned or is not thoroughly cleaned.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a cleaning device for construction formwork, comprising:

[0011] The housing frame has a supporting base frame fixedly connected to its lower part by bolts, and an integrated plate frame part is horizontally provided at the connection between the housing frame and the supporting base frame.

[0012] Also includes:

[0013] An adjustable conveying mechanism is symmetrically arranged about the horizontal central axis of the formwork section. It is used for bearing the formwork and for automatic conveying during formwork cleaning. The adjustable conveying mechanism forms a sliding adjustment structure on the formwork section, which can adapt to formwork of different specifications and sizes.

[0014] The automatic sliding shovel mechanism has a sliding structure on the left section of the machine frame. It achieves automated mechanical cleaning of concrete residue on the building formwork through reciprocating sliding and shoveling operations. In addition, it cooperates with the prying action during the sliding operation to achieve thorough cleaning of even stubborn concrete residue.

The reduction motor is fixedly mounted on the upper side wall of the housing through bolts, and the drive wheel is connected to the side of the building template by a pressing fit.

[0016] In this case, both the left and right ends of the support plate in the shell are rotatably connected to auxiliary wheels, and the auxiliary wheels are in close contact with the bottom surface of the building template.

[0017] Preferably, pressure roller assemblies are flipped and connected to both the left and right sides of the machine frame.

[0018] The support frame is symmetrically arranged about the horizontal central axis of the pressure roller body, and the pressure roller body forms a rotating structure at the lower end of the support frame. The pressure roller body is connected to the top surface of the building template by pressing and adhering.

[0019] Preferably, the automatic sliding shovel mechanism includes a U-shaped frame, a linkage frame, a round shaft frame, and a blade body. The U-shaped frame is slidably connected to the left section of the housing cavity of the machine frame, and the transverse frame of the U-shaped frame is slidably connected to the linkage frame by a guide rod. The lower end of the longitudinal frame of the U-shaped frame is rotatably connected to the round shaft frame by a bearing, and the inward end of the round shaft frame is fixedly connected to the end of the blade body by bolts.

[0020] The shovel body is set in an inclined upward state, and the shovel body forms a flipping structure on the "U"-shaped carrier with the assistance of the round shaft frame. The shovel body is connected to the bottom surface of the building formwork by overlapping and fitting.

[0021] Preferably, a first spring is installed at the connection between the "U"-shaped carrier and the linkage frame, and electric telescopic rods are provided at both the front and rear sections of the linkage frame. The output end of the electric telescopic rod is fixedly connected to the linkage frame by bolts, and the electric telescopic rod is fixedly installed on the right section of the housing cavity wall of the housing frame by bolts.

[0022] The linkage frame has an integrated push plate at both its front and rear ends, which are horizontally facing left. The linkage frame slides within the left section of the housing cavity with the assistance of the push plate.

[0023] Preferably, the upper section of the longitudinal frame of the "U"-shaped carrier is telescopically slidably connected to the main transmission plate, and a second spring is installed at the connection between the main transmission plate and the "U"-shaped carrier, and an inclined sidewall is provided at the lower end of the main transmission plate.

[0024] The upper end of the main drive plate is connected to the push plate by a pushing and pressing method, and the end of the push plate facing the main drive plate has an inclined sidewall.

[0025] Preferably, the lower end of the longitudinal frame in the "U"-shaped carrier is slidably connected to the outer frame cavity with a secondary transmission block, and the inclined groove cavity wall in the secondary transmission block is pressed and fitted against the inclined side wall in the main transmission plate.

[0026] The auxiliary transmission block is connected to the round shaft frame in a sliding manner with the assistance of a guide rod, and a third spring is installed at the connection between the auxiliary transmission block and the round shaft frame. The auxiliary transmission block is provided with an integrated second spiral block on the side facing the round shaft frame.

[0027] Preferably, the circular shaft frame is provided with an integrated first spiral block on the side facing the auxiliary transmission block, and the spiral wall of the first spiral block and the spiral wall of the second spiral block are pressed and connected together.

[0028] Preferably, a torsion spring is installed at the connection between the round shaft frame and the "U"-shaped carrier frame, and a sealing ring is fixedly engaged at the lower end of the longitudinal frame of the "U"-shaped carrier frame, and the sealing ring is pressed and connected to the side wall of the blade body.

[0029] Compared with the prior art, the beneficial effects of the present invention are: the cleaning device for building formwork, through the reciprocating sliding shovel operation, is different from the traditional time-consuming and laborious manual cleaning operation, and realizes the mechanical and automated cleaning process. In addition, in order to deal with more stubborn concrete debris residue, the sliding shovel cleaning is combined with the prying action to achieve the purpose of thoroughly cleaning the building formwork.

[0030] 1. Equipped with drive wheels and a blade body, auxiliary wheels are rotatably mounted on both the left and right ends of the support plate in the housing base. The auxiliary wheels support and adhere to the bottom surface of the building formwork. Pressure roller assemblies are installed on both the left and right sides of the machine frame. The pressure roller body presses against and adheres to the top surface of the building formwork. The front and rear drive wheels press against and adhere to the front and rear sides of the building formwork, respectively. The auxiliary wheels, pressure roller assemblies and drive wheels work together to position and limit the building formwork for bearing the building formwork. The rotation of the drive wheels drives the automatic conveying of the building formwork during cleaning, assisting the subsequent automatic cleaning operation.

[0031] Furthermore, during the automatic conveying of the building formwork, the blade body overlaps and fits against the bottom surface of the building formwork. Through the elastic support of the first spring and the limiting ring on the guide rod in the linkage frame, the "U"-shaped carrier is limited and pushed, causing the linkage frame to drive the "U"-shaped carrier to slide back and forth. The "U"-shaped carrier then drives the blade body to slide back and forth synchronously. Through the reciprocating sliding operation, the concrete debris residue on the building formwork is cleaned automatically, achieving mechanical and automated cleaning. This is different from the traditional time-consuming and laborious manual cleaning operation, making its work efficiency far higher than manual cleaning, reducing the workload of cleaning personnel, and achieving the purpose of convenient and easy cleaning.

[0032] Furthermore, the blade head of the shovel body is on the same horizontal plane as the auxiliary wheel. The housing drives the drive wheel to form a sliding adjustment structure on the plate frame. The bracket drives the pressure roller body to form a flipping adjustment structure on the machine housing frame. To cope with building templates of different specifications and sizes, this building template cleaning device can be freely adjusted to meet the cleaning needs of building templates of different specifications, effectively improving the scope of application.

[0033] 2. Equipped with a circular shaft frame and a secondary transmission block, the blade body is restricted by stubborn residual concrete. The linkage frame slides on the "U"-shaped carrier. Through the push plate part pushing the main transmission plate, and through the cooperation between the inclined side wall in the main transmission plate and the inclined groove wall in the secondary transmission block, the secondary transmission block is driven to slide. Then, through the cooperation between the second spiral block and the first spiral block, the circular shaft frame drives the blade body to rotate. To deal with more stubborn concrete debris residue, the sliding blade cleaning is combined with the prying action to achieve the purpose of thoroughly cleaning the building formwork and ensuring the cleaning quality of the building formwork.

[0034] Furthermore, the blade body is not restricted by stubborn residual concrete. After the "U"-shaped carrier slides, it is restricted by the shell cavity wall of the machine frame. Based on the above, the linkage frame slides on the "U"-shaped carrier, causing the round shaft frame to drive the blade body to rotate. This shakes off and cleans the residual concrete adhering to the blade body, solving the problem of not being able to clean it completely. Attached Figure Description

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Please see Figure 1-11 The present invention provides a technical solution: a cleaning device for building construction templates, including a housing frame 1, an adjustable conveying mechanism 2, and an automatic sliding shovel mechanism 3.

[0049] Before use, the formwork cleaning device has adjustable conveyor mechanisms 2 arranged symmetrically about the horizontal center axis of the formwork frame 101, forming a sliding adjustment structure on the formwork frame 101. The distance between the two adjustable conveyor mechanisms 2 needs to be adjusted according to the width of the formwork. Specifically, according to… Figure 1 , Figure 2 and Figure 3As shown, an integrated plate frame 101 is horizontally arranged at the connection between the housing frame 1 and the supporting base frame therein. The plate frame 101 has an adjustment groove parallel to it, which is symmetrically arranged about its central axis. Since the housing cavity of the housing 4 is equipped with a drive wheel 5, after the housing 4 is placed, its lower side housing wall overlaps and fits against the plate frame 101, and is arranged in a vertical state. Since the connection between the housing 4 and the plate frame 101 is equipped with a fixing bolt for locking, the housing 4 is slidably adjusted on the plate frame 101, so that the fixing bolt in the housing 4 slides along the adjustment groove in the plate frame 101, that is, the two front and rear adjustable conveying mechanisms 2 are slidably adjusted in opposite directions. After the housing 4 is slidably adjusted, the drive wheel 5 presses against and fits against the side of the building template, so that the two front and rear adjustable conveying mechanisms 2 clamp and position the building template.

[0050] Since the fixing bolts in the housing 4 are symmetrically arranged about its central axis, after the housing 4 is installed, the fixing bolts move through the adjustment groove in the plate frame 101, and the fixing bolts are threadedly fixed to the lower housing wall of the housing 4. After the housing 4 is slidably adjusted, the fixing bolts in the housing 4 are screwed on so that the bolt cap part of the fixing bolt is pressed and fixed on the plate frame 101, thus completing the locking after adjustment.

[0051] Before use, the cleaning device for construction formwork has pressure roller assemblies 8 installed on both the left and right sides of the machine frame 1. The two pressure roller assemblies 8 are combined to form an "eight" shape. The positions of the two pressure roller assemblies 8 need to be adjusted according to the thickness of the construction formwork. Specifically, according to... Figure 1 , Figure 2 and Figure 4 As shown, an integrated support plate is horizontally arranged on the inward side of the lower end of the shell 4. Since auxiliary wheels 7 are provided at both ends of the support plate in the shell 4, the front and rear ends of the building template overlap on the support plate in the front and rear shells 4 respectively, so that the bottom surface of the building template is supported and connected to the auxiliary wheels 7.

[0052] Since the support 801 is set in an inclined state after installation, it is symmetrically arranged about the horizontal central axis of the pressure roller body 802. The pressure roller body 802 is in a horizontal state and is rotatably set at the lower end of the support 801. It is driven by the support 801 to form a synchronous motion structure. Since the four corner ends of the machine frame 1 are all provided with open cavities, the upper end of the support 801 is rotatably connected to the shaft column. After installation, the upper end is movably inserted into the end cavity of the machine frame 1. The two ends of the shaft column are respectively inserted and fixed to the side cavity walls by bolts. The upper end of the support 801 is rotated and flipped on the machine frame 1, that is, the left and right pressure roller assemblies 8 are flipped and adjusted in opposite directions. After the support 801 is flipped and adjusted, the pressure roller body 802 is pressed against and adhered to the top surface of the building template. The building template is positioned and restricted by the mutual cooperation of the pressure roller body 802, the auxiliary wheel 7 and the drive wheel 5.

[0053] Because an arc-shaped adjustment groove 102 is provided at the connection between the bracket 801 and the housing frame 1, the arc-shaped adjustment groove 102 is opened on the end cavity wall of the housing frame 1 and is set in a through state, and its arc center coincides with the rotation center of the bracket 801. Furthermore, because a fixing bolt for locking the bracket 801 is provided in the arc-shaped adjustment groove 102, the fixing bolt moves through the arc-shaped adjustment groove 102 and is threadedly fixed to the bracket 801. When the bracket 801 is flipped and adjusted, the fixing bolt in the bracket 801 slides along the arc-shaped adjustment groove 102. After the bracket 801 is flipped and adjusted, the fixing bolt in the bracket 801 is screwed so that the bolt head part of the fixing bolt presses against and fixes against the groove edge of the arc-shaped adjustment groove 102, thus completing the locking after adjustment.

[0054] This construction formwork cleaning device, during use, utilizes two adjustable conveyor mechanisms 2 at the front and rear for supporting the construction formwork and for automatic conveying during formwork cleaning. Specifically, according to... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a support base is fixedly connected to the bottom of the housing frame 1 by bolts. The support base has an open frame structure. The construction template cleaning device is fixed to the construction site with the assistance of the support base in the housing frame 1, so that the housing frame 1 is set in a horizontal state. The construction template is inserted through the frame of the "U" shaped carrier 9, so that the front and rear ends of the construction template overlap the support plate part in the front and rear housing seats 4 respectively, and the left and right pressure roller bodies 802 are pressed against and adhered to the top surface of the construction template, thus completing the positioning and placement of the construction template.

[0055] Since the center of the drive wheel 5 is provided with an integrated shaft column, the upper and lower ends of which are fixedly clamped with bearings, after installation, the upper and lower ends of the shaft column, together with the bearings, are movably inserted into the upper and lower shell walls of the housing 4. Since the geared motor 6 is installed and fixedly mounted on the upper shell wall of the housing 4 with bolts, the output end is movably inserted into the shell cavity of the housing 4, and the output end is fixedly clamped to the upper end of the shaft column of the drive wheel 5. When the geared motor 6 is started, the drive wheel 5 rotates in the shell cavity of the housing 4 with the assistance of the bearings. The rotation directions of the drive wheels 5 in the front and rear housings 4 are opposite.

[0056] Since the front and rear walls of the shell cavity in the shell base 4 are both open, the drive wheel 5 extends outward through the opening of the shell cavity of the shell base 4 after it is installed, and it is connected to the side of the building template by pressing and fitting. Furthermore, since the outer side of the drive wheel 5 is fixedly fitted with a rubber sleeve, and the outer side of the rubber sleeve is provided with anti-slip grooves at equal intervals, the friction between the drive wheel 5 and the building template is enhanced. After the drive wheel 5 rotates, it drives the building template to move automatically.

[0057] Because auxiliary wheels 7 are provided at both ends of the support plate in the shell 4, and a shaft is rotatably connected to the center of the auxiliary wheel 7, it is placed in the groove of the support plate in the shell 4 after being installed. The two ends of the shaft are respectively inserted and fixed to the walls of the groove on both sides by bolts, and it is in close contact with the bottom surface of the building formwork. When the building formwork is driven to be conveyed, the auxiliary wheel 7 rotates on the support plate in the shell 4 to carry the building formwork and assist in the automatic horizontal conveying of the building formwork.

[0058] Since the length of the pressure roller body 802 is greater than the length of the blade body 12, and the length of the blade body 12 is greater than the width of the largest specification building template, an integrated shaft column is set at the center of the pressure roller body 802. Bearings are fixedly clamped at both ends of the shaft column, and it is placed between the front and rear supports 801. The front end and rear end of the shaft column, along with bearings, are respectively inserted into the lower ends of the front and rear supports 801. Moreover, it is connected to the top surface of the building template by pressing and adhering. When the building template is driven to be conveyed, the pressure roller body 802 rotates at the lower end of the support 801, further assisting the automatic horizontal conveying of the building template.

[0059] When in use, the automatic sliding scraper mechanism 3 is installed vertically downwards on the machine frame 1 and connected to the construction formwork in a movable, interlocking manner. It forms a sliding structure on the left side of the machine frame 1. Through reciprocating sliding and scraping operations, it achieves automated mechanical cleaning of concrete residue on the construction formwork. During the sliding scraper operation, a prying motion is used to thoroughly clean even stubborn concrete residue. After cleaning one side of the construction formwork, it is flipped over for further cleaning. Specifically, according to… Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, electric telescopic rods 14 are provided in both the front and rear sections of the linkage frame 10. After the electric telescopic rods 14 are installed, they are fixedly installed on the right section cavity wall of the housing frame 1 with bolts, and are set in a horizontal position facing left. The output end is movably inserted into the left section cavity of the housing frame 1, and the output end is inserted and fixedly connected to the linkage frame 10 with bolts. When the electric telescopic rods 14 are started, they extend and operate, driving the linkage frame 10 to move.

[0060] Since the front and rear ends of the upper cavity wall of the left section of the housing frame 1 are provided with "convex" shaped grooves, and the front and rear ends of the linkage frame 10 are provided with integrated push plate parts 1001 horizontally facing left, and since the longitudinal section of the push plate parts 1001 is "I" shaped, after the linkage frame 10 is installed, the two push plate parts 1001 are respectively movably inserted into the two "convex" shaped grooves in the housing frame 1, so that the linkage frame 10 is positioned on the housing frame 1 in a movable state. After the linkage frame 10 is driven, it slides on the housing frame 1 with the assistance of the push plate parts 1001.

[0061] Because a first spring 13 is installed at the connection between the "U"-shaped carrier 9 and the linkage frame 10, the first spring 13 is movably sleeved outside the guide rod in the linkage frame 10. One end of the first spring 13 presses against the transverse frame in the "U"-shaped carrier 9, and the other end presses against the linkage frame 10. Through the elastic support of the first spring 13, the linkage frame 10 drives the "U"-shaped carrier 9 to move synchronously.

[0062] Since the left section of the housing frame 1 has wedge-shaped grooves on both the front and rear sides of the cavity wall, the "U"-shaped carrier 9 is divided into two parts: a transverse frame and a longitudinal frame. The front and rear ends of the transverse frame are equipped with integrated wedge-shaped limiting blocks. After the "U"-shaped carrier 9 is installed, the transverse frame is movably locked in the left section of the housing frame 1, and the two wedge-shaped limiting blocks are movably inserted into the two wedge-shaped grooves, so that the "U"-shaped carrier 9 is positioned on the housing frame 1 in a movable state. When the "U"-shaped carrier 9 is driven, it slides synchronously with the linkage frame 10 in the left section of the housing frame 1.

[0063] Because the scraper body 12 is positioned horizontally between the two longitudinal frames of the "U"-shaped carrier 9, it forms a synchronous movement structure with the "U"-shaped carrier 9. Furthermore, its blade head is on the same horizontal plane as the auxiliary wheel 7. Since the scraper body 12 is installed at an upward angle, it is connected to the bottom surface of the building formwork via an overlapping joint. When the "U"-shaped carrier 9 slides, it drives the scraper body 12 to slide synchronously, allowing the scraper body 12 to perform a scraping operation on the bottom surface of the building formwork, thus cleaning the concrete residue on the formwork. Based on the above, through the reciprocating extension and retraction of the electric telescopic rod 14, when the linkage frame 10 slides, the elastic support of the first spring 13 causes the linkage frame 10 to drive the "U"-shaped carrier frame 9 to slide synchronously. When the linkage frame 10 returns to its original position, the limiting ring on the guide rod in the linkage frame 10 limits and pushes the "U"-shaped carrier frame 9, causing the linkage frame 10 to drive the "U"-shaped carrier frame 9 to slide synchronously back to its original position. This drives the shovel body 12 to perform reciprocating sliding cleaning operations on the building template, achieving the requirements of automated mechanical cleaning.

[0064] When dealing with stubborn concrete residue, the blade body 12 is restricted during scraping. Even if the "U"-shaped carrier 9 stops sliding, the linkage frame 10 continues to slide. Because the linkage frame 10 has integrated guide rods evenly spaced on one side facing the "U"-shaped carrier 9, with limit rings connected to the ends of the guide rods via bolts, the linkage frame 10 is positioned parallel to the transverse frame of the "U"-shaped carrier 9 after installation. The guide rods, along with the limit rings, are movably inserted into the "U"-shaped carrier 9. Within the slot of the transverse frame in the "U"-shaped carrier 9, the linkage frame 10 is positioned in a movable state on the "U"-shaped carrier 9. Since a first spring 13 is installed at the connection between the "U"-shaped carrier 9 and the linkage frame 10, the linkage frame 10 continues to slide after the "U"-shaped carrier 9 is restricted. This allows the linkage frame 10 to slide in the transverse frame of the "U"-shaped carrier 9 with the assistance of the guide rod, and causes the first spring 13 to undergo elastic deformation under compression. The first spring 13 is used for the reset sliding of the linkage frame 10 on the "U"-shaped carrier 9.

[0065] Since the main drive plate 15 is movably inserted into the upper section of the longitudinal frame cavity in the "U"-shaped carrier 9 after installation, its upper end extends outward through the upper section of the frame cavity, and its upper end is set in a rounded chamfered structure. Since the end of the push plate part 1001 has an inclined sidewall facing the main drive plate 15, it is set in a vertically offset state with the transverse frame in the "U"-shaped carrier 9. After the linkage frame 10 is installed, the push plate part 1001 fits against the upper side of the transverse frame in the "U"-shaped carrier 9. After the linkage frame 10 slides on the "U"-shaped carrier 9, with the assistance of the inclined sidewall in the push plate part 1001, the push plate part 1001 pushes and presses against the upper end of the main drive plate 15, and the main drive plate 15 slides and contracts in the upper section of the longitudinal frame cavity in the "U"-shaped carrier 9.

[0066] Because the upper section of the longitudinal frame cavity in the "U"-shaped carrier 9 has an integrated protrusion, and the middle of the main transmission plate 15 has a spring groove, after the protrusion on the longitudinal frame of the "U"-shaped carrier 9 is installed, it is movably locked in the spring groove, so that the main transmission plate 15 is in a movable state in the longitudinal frame of the "U"-shaped carrier 9. Also, because a second spring 16 is installed at the connection between the main transmission plate 15 and the "U"-shaped carrier 9, after the second spring 16 is installed, it is movably inserted into the spring groove of the main transmission plate 15. One end of the second spring 16 is fixedly locked on the groove wall of the spring groove of the main transmission plate 15, and the other end of the second spring 16 is fixedly locked on the protrusion in the "U"-shaped carrier 9. When the main transmission plate 15 contracts and slides, the second spring 16 is compressed and undergoes elastic deformation. The second spring 16 is used for the main transmission plate 15 to reposition and extend and slide on the "U"-shaped carrier 9.

[0067] Since the auxiliary transmission block 17 has a slot in the middle that corresponds to the main transmission plate 15, and the slot wall is inclined, and since the lower end of the main transmission plate 15 has an inclined side wall, after it is installed, the lower end is movably inserted into the lower end of the longitudinal frame facing outward into the frame cavity, and movably inserted into the middle slot of the auxiliary transmission block 17, and the inclined side wall is pressed and fitted against the inclined slot wall in the auxiliary transmission block 17. After the main transmission plate 15 contracts and slides, the auxiliary transmission block 17 is pushed to move through the sliding fit between the inclined side wall in the main transmission plate 15 and the inclined slot wall in the auxiliary transmission block 17.

[0068] Since the lower end of the longitudinal frame in the "U"-shaped carrier 9 is divided into an inward frame cavity and an outward frame cavity, and since the longitudinal section of the auxiliary transmission block 17 is square, after it is installed, it is movably inserted into the lower end of the outward frame cavity of the longitudinal frame in the "U"-shaped carrier 9, and is set in a movable positioning state. When the auxiliary transmission block 17 is driven, it slides in the lower end of the outward frame cavity of the longitudinal frame in the "U"-shaped carrier 9.

[0069] Since the central part of the circular shaft frame 11 has a slot, the auxiliary transmission block 17 has an integrated guide rod in the central part of the side facing the circular shaft frame 11. After installation, the guide rod is movably inserted into the slot of the circular shaft frame 11. Since a third spring 18 is installed at the connection between the auxiliary transmission block 17 and the circular shaft frame 11, the third spring 18 is movably inserted into the slot of the circular shaft frame 11. One end of the third spring 18 is fixedly clamped to the wall of the slot of the circular shaft frame 11, and the other end is fixedly clamped to the end of the guide rod of the auxiliary transmission block 17. After the auxiliary transmission block 17 is driven to slide, the guide rod assists the auxiliary transmission block 17 to slide on the circular shaft frame 11, and the third spring 18 is compressed and undergoes elastic deformation. The third spring 18 is used for the reset sliding of the auxiliary transmission block 17 on the circular shaft frame 11.

[0070] Because the auxiliary transmission block 17 is provided with an integrated second spiral block 1701 on the side facing the circular shaft frame 11, and two second spiral blocks 1701 are arranged in a ring array about their spiral center, and the circular shaft frame 11 is provided with an integrated first spiral block 1101 on the side facing the auxiliary transmission block 17, and two first spiral blocks 1101 are arranged in a ring array about their spiral center, the spiral wall of the first spiral block 1101 and the spiral wall of the second spiral block 1701 are pressed and connected. Because the specifications and dimensions of the first spiral block 1101 and the second spiral block 1701 are compatible, their spiral centers coincide. Furthermore, because the length of the second spiral block 1701 is greater than the maximum sliding distance of the auxiliary transmission block 17, when the auxiliary transmission block 17 is driven to slide, the circular shaft frame 11 rotates through the sliding cooperation between the second spiral block 1701 and the first spiral block 1101.

[0071] Since the longitudinal section of the round shaft frame 11 is set in a "T" shape, the outer and inner ends of its shaft are fixedly connected with bearings. After it is installed, the bearings are movably inserted into the inner frame cavity at the lower end of the longitudinal frame in the "U" shaped carrier 9, and it is set in a movable positioning state. When the round shaft frame 11 is driven, it rotates at the lower end of the longitudinal frame in the "U" shaped carrier 9 with the assistance of the bearings.

[0072] Since a torsion spring 19 is installed at the connection between the round shaft frame 11 and the "U"-shaped carrier 9, the torsion spring 19 is movably sleeved outside the round shaft frame 11 after installation. One end of the torsion spring 19 is fixedly clamped to the round shaft frame 11, and the other end is fixedly clamped to the lower end of the longitudinal frame of the "U"-shaped carrier 9 facing the inner wall of the frame cavity. After the round shaft frame 11 rotates, the torsion spring 19 is subjected to force and undergoes elastic deformation. The torsion spring 19 is used for the reset rotation of the round shaft frame 11 on the "U"-shaped carrier 9.

[0073] After the round shaft frame 11 is installed, its inward end moves through the inward frame cavity and extends outward. After the blade body 12 is installed, its two ends are respectively inserted into the inward ends of the two round shaft frames 11 and fixed together with bolts. The two form a synchronous rotation structure. After the round shaft frame 11 rotates, the blade body 12 will rotate on the "U" shaped carrier 9 to achieve prying and cleaning of stubborn concrete residue.

[0074] Because the lower end of the longitudinal frame of the "U"-shaped carrier 9 is fixedly connected with a sealing ring 20, the sealing ring 20 is pressed and connected to the side wall of the blade body 12, which is used for sealing between the "U"-shaped carrier 9 and the blade body 12, so as to prevent dust from entering the lower end of the longitudinal frame cavity of the "U"-shaped carrier 9.

[0075] When there is no way to deal with stubborn concrete residue, after the "U" shaped carrier 9 slides completely, it is restricted by the shell cavity wall of the casing frame 1. At this time, the linkage frame 10 is driven to continue sliding. According to the above, it drives the blade body 12 to perform a flipping motion, so as to shake off and clean the residual concrete adhering to the blade body 12.
