Description

Technical Field

[0001] The invention belongs to the technical field of building construction plastering, in particular to a multifunctional block plastering device and a quick plastering method. Background Art

[0002] For thousands of years, the Chinese masonry culture based on "Qin bricks and Han tiles" has a long history. Masonry buildings focus on the coordination of nature and life, forming a unique Chinese architectural system. Masonry structure refers to a structure in which walls and columns built by blocks and mortar are the main load-bearing components of a building. It is a general term for brick masonry, block masonry and stone masonry structures. With the rapid development of my country's economy, the urbanization process is getting faster and faster, and the demand for the construction industry has also increased. Among them, the use of blocks is very extensive in the construction industry, such as wall construction, foundation, slope protection engineering, etc. In addition, block plastering is a common construction process in construction projects. The main function of block plastering mortar is force transmission and bonding, which can increase the strength and stability of the masonry structure, thereby improving the safety of the overall structure. However, at present, most of the block plastering processes are carried out by manual plastering. This method usually uses a trowel for manual smoothing, which has high technical requirements for on-site construction personnel. The fullness of the mortar and the quality of the mortar joints are difficult to control during plastering, and the construction quality is difficult to guarantee. This not only affects the stability of the building, but also directly affects the safety of the building structure.

[0003] Most of the existing block plastering devices are manually plastered with a plastering knife. In the plastering process of this device, the construction workers generally use an iron trowel for construction, and at the same time need to cooperate with a mortar bucket, put the mortar material into the mortar bucket, take the material in the mortar bucket by the iron trowel, and apply the mortar material to the masonry structure. In addition, the problem of uneven plastering thickness is very easy to occur during the block plastering process. This will cause the bonding performance of some areas of the structure to be good, and the bonding performance of some areas to be poor, which will eventually affect the stability and safety of the overall structure. Therefore, most inventors use a plastering thickness controller to control the plastering thickness with a plastering knife to solve the problem of uneven plastering thickness. A typical example is the application with Chinese Publication No. CN219808657U. The inventor adjusts and fixes the extension amount of the steel extension piece, so that the end of the steel extension piece contacts the wall surface, and the plastering knife moves upward in a state parallel to the plastering surface, so as to achieve the same plastering thickness as the extension length of the steel extension piece, thereby making the plastering thickness adjustable, ensuring the plastering quality, and making the plastering thickness more uniform. However, this device still relies on workers to manually plaster, which limits the efficiency of block plastering to a certain extent. For this defect, as in the application with Chinese publication number CN215948974U, the inventor transports the plaster material to the masonry structure that needs to be plastered, and then loads the plaster material into the guide hopper, and pulls the guide hopper along the masonry direction. During the pulling process, the plaster material in the guide hopper flows out along the discharge port and is evenly applied to the masonry structure through the plastering plate. Compared with the prior art, the guide hopper can increase the amount of plaster applied at one time, thereby reducing the number of material retrievals and increasing the efficiency of plastering. However, the plastering width of the device is fixed, and the width cannot be adjusted to quickly plaster blocks of different widths, which limits the scope of application of plastering. In addition, the storage space for plaster material in this device can be further improved, thereby better reducing the number of material retrievals.

[0004] In addition, during the construction of high-structure block plastering, most construction workers stand on ladders and hold plastering knives to plaster, which not only affects the efficiency of block plastering construction, but also easily causes safety accidents. In this regard, as in the application with Chinese publication number CN208220239U, the inventors added a storage hopper to store mortar, saving the time of placing mortar in the plastering trough every time plastering, thereby improving construction efficiency. This device is also equipped with a pulley, which can easily push the plastering template, reduce the number of times workers move the ladder, and improve the safety of construction. However, this device needs to be pulled manually for plastering, and there are still certain construction risks.

[0005] In view of the above problems, it is very necessary for the inventor to design a block plastering device which has uniform plastering, adjustable plastering thickness, adjustable width, large storage of mortar, automatic plastering and high efficiency. Summary of the invention

[0006] To remedy the above problems, the purpose of the present invention is to provide a multifunctional block plastering device and a quick plastering method to solve the problems of existing block plastering devices, such as serious waste of mortar in the process of taking and applying materials, uneven mortar application, inability to adjust the width of the device, inability to store mortar, and inability to efficiently and automatically plaster, so as to further improve the plastering efficiency of block plastering and the quality of masonry structure construction projects.

[0007] In order to achieve the above object, the technical solution of the present invention to solve the above technical problem is as follows:

[0008] A multifunctional block plastering device and a quick plastering method, comprising a wireless small remote control, an electric wheel, a transmission crawler, a driven pulley, a motor, a driving pulley, a rotating connecting rod, an electric box, a bottom fender, a connecting plate, a receiving antenna of the electric box, a tail baffle, a rotating fixing device, a T-shaped rotating rod, a connecting round rod, a pentagonal nut, a circular gasket, a ram horn nut, a plastering template, a handle, a horizontal pulley, a rotating shaft rod, a scale meter, a baffle, a discharging plate, a storage hopper, a filter hopper, fixing bolts, and a plastering scraper, which are arranged in sequence from left to right.

[0009] Furthermore, the device can meet various plastering requirements of the plastering scraper, complete the rapid plastering work of blocks of different widths and plaster layers of different thicknesses, realize automated plastering, and reduce the risk of high-structure block plastering construction.

[0010] Furthermore, the working principle of the electric wheel is mainly controlled by a small wireless remote control. When the worker clicks the button of the remote control, the signal will be transmitted from the transmitting antenna of the remote control and successfully received by the receiving antenna of the electric box, thereby starting the electric box to generate electricity and activating the motor to rotate.

[0011] Furthermore, the active pulley can be successfully driven to rotate by the engine, so that the transmission belt can rotate, and then the transmission belt can drive the driven pulley to rotate, and then drive the rotating connecting rod to rotate, and finally successfully drive the electric wheel to rotate.

[0012] Furthermore, the partial device is provided with two engines, which can ensure sufficient power to drive the entire plastering device to work along the plastering route.

[0013] Furthermore, the active pulley part uses a smaller gear-type pulley, which can be equivalent to a reducer, can reduce the rotation speed of the driven pulley, and can also prevent the motor from overloading. This can make the plastering device more stable during movement, increase the service life of parts, and reduce construction costs.

[0014] Furthermore, the device is also designed with a bottom fender and a connecting plate. The bottom fender can prevent important parts from contacting the plaster mortar to a certain extent, thereby ensuring the normal operation of the electric wheel.

[0015] Furthermore, the connecting plate is intended to be combined with the T-shaped rotating rod so that this part of the device is connected to the overall device to form a whole, thereby achieving efficient automatic plastering.

[0016] Furthermore, a tail baffle is provided at the end of the device for installing a rotating fixing device, so that the T-shaped rotating rod can perform axial vertical rotation. This allows the electric wheel to work normally on planes at different heights to meet the needs of the plastering device for plastering of different thicknesses.

[0017] Furthermore, a hole is provided in the tail of the plastering template to allow the tail baffle to pass through without affecting the movement and width adjustment of the two plastering templates.

[0018] Furthermore, two circular holes and a polygonal hole are provided in the plastering template, so that the connecting round rod, the tail baffle and the plastering scraper pass through the holes to connect the two plastering templates.

[0019] Furthermore, the device can adjust the width to clamp blocks of different widths by horizontally moving two plastering templates. When the width is adjusted to a suitable width, the outer ram nut and circular washer, the inner pentagonal nut and circular washer can be tightened along the connecting round rod. A total of 4 sets of such inner and outer combinations can fix the width between the two plastering templates, allowing the device to work stably and completely normally and meet the requirements of plastering different blocks.

[0020] Furthermore, the device is provided with a handle above the plastering template to facilitate moving the plastering device and quickly enter the next stage of plastering construction.

[0021] Furthermore, six horizontal pulleys are arranged under the plastering template to assist the electric wheels in working, so that the plastering template can be moved more easily.

[0022] Furthermore, a storage hopper is provided on the upper part of the plastering template, and its internal space is large, which can store sufficient mortar, saving the time of placing mortar in the plastering groove every time plastering, and improving construction efficiency.

[0023] Furthermore, the storage hopper contains a filter hopper, and a plurality of filter holes are provided on the filter hopper to filter out large particles of mortar, thereby ensuring the flatness and fullness of the mortar and improving the construction quality.

[0024] Furthermore, a discharge port is provided on the inner side of the plastering template. When plastering the blocks, the worker can pull up the material blocking door, and the mortar will flow from the discharge port along the inclined groove (56) into the interior of the plastering device.

[0025] Furthermore, the device starts the electric wheel. Under the action of the plastering scraper, the plastering device can spread a highly uniform mortar layer, thereby improving the construction quality and efficiency.

[0026] The beneficial effects of the present invention are:

[0027] (1) The device designed by the present invention can horizontally move two plastering templates along the direction of the connecting round rod. This method plays a role in adjusting the width of the plastering device. After adjusting the width suitable for the building block, the pentagonal nut and the ram horn nut can fix the entire plastering device to ensure that the plastering device has good stability during the working process. In addition, a scale is set on the surface of the plastering template. The worker can vertically lift the entire device by observing the scale, thereby changing the distance between the plastering scraper and the surface of the building block. After that, the plastering device can apply plastering layers of different thicknesses and high uniformity. Finally, this device can be used to apply plastering layers of different thicknesses and high uniformity to building blocks of different widths to meet the construction of different application scenarios. In addition, this plastering device reduces the difficulty of plastering for construction workers, solves the problem of high unevenness in manual plastering, improves construction quality, and is suitable for promotion and use.

[0028] (2) The present invention designs an electric wheel and is equipped with a corresponding remote control. Workers can use a wireless remote control to control the switch of the electric wheel. After the plastering starts, the electric wheel can drive the entire plastering device to work along the plastering route. In addition, 6 horizontal pulleys are arranged at the bottom of each plastering template to assist the movement of the plastering device, making the movement of the device easier and smoother. The above-mentioned improved method can greatly improve the construction efficiency of workers in block plastering. In addition, when performing block plastering on higher structures, workers can use a wireless remote control to control the movement of the plastering device after fixing the device in the original position, without the need for frequent movement to perform block plastering. This device further improves the safety of plastering construction, and improves the practicality of the device while saving manpower and improving work efficiency.

[0029] (3) The present invention is provided with a storage hopper, and a large storage space is also provided inside the plastering template. The storage hopper can store large mortar, saving the time of placing mortar in the plastering groove every time plastering is performed, improving construction efficiency, and further avoiding the problem of workers repeatedly shoveling mortar and causing mortar splashing, thereby further improving the working environment of workers. In addition, a detachable filter hopper is provided in the storage hopper to filter out large particles of mortar, ensure the flatness and fullness of the mortar, and improve the construction quality. In addition, the storage hopper, the storage hopper neck and the filter hopper are detachably connected to facilitate cleaning of the stored materials. . BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] In order to better illustrate the present invention and facilitate understanding of the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with specific implementation methods.

[0041] like Figures 1 to 8 As shown, a multifunctional block plastering device comprises a wireless small remote controller (1), an electric wheel (2), a driving crawler (21), a driven pulley (22), a motor (23), a driving pulley (24), a rotating connecting rod (25), an electric box (26), a bottom fender (27), a connecting plate (28), a receiving antenna (29) of the electric box, a tail baffle (3), a rotating fixing device (31), a T-shaped rotating rod (32), a connecting round rod (4), a pentagonal nut (41), a circular gasket (42), a horn nut (43), a plastering template (5), a handle (51), a horizontal pulley (52), a rotating shaft (53), a scale (54), a baffle (55), a discharging plate (56), a storage hopper (6), a filtering hopper (61), a fixing bolt (62), and a plastering scraper (7). With the coordinated work of these parts, the block plastering device can efficiently perform block plastering.

[0042] The main features and principles of this device are as follows: A wireless small remote controller (1) can control the start and stop of the electric wheel (2). The remote controller transmitting antenna (11) transmits a signal. After the signal is transmitted to the receiving antenna (29) of the electric box, the electric box (29) starts to generate electricity, activates the motor (23), and causes the driving pulley (24) to rotate at high speed. Through the transmission track (21), the driven pulley (29) also rotates. Finally, the electric wheel (2) rotates.

[0043] A bottom fender (27) is also provided at the bottom of the electric wheel to protect important parts of the device and to increase the service life of the device. One end of the T-shaped rotating rod (32) is connected to the connecting plate (28) of the electric wheel (2), and the other end is connected to the rotating fixing device (31), so that the electric wheel (2) can be rotated vertically to adjust the distance between the plastering scraper and the building block, so that the electric wheel (2) can work normally after different plastering layer thicknesses.

[0044] In addition, the plastering template (5) is provided with a tail baffle hole (510), a plastering scraper hole (59) and a round rod hole (58) to avoid affecting the distance between the plastering templates (5). The worker can horizontally move the two plastering templates (5) along the direction of the connecting round rod (4) to meet the requirements of plastering construction for blocks of different widths. After adjusting to a suitable width, the worker can tighten the pentagonal nut (41) and the ram's horn nut (43) to fix the plastering device and make the two plastering templates (5) fit the side surface of the block tightly.

[0045] In addition, the worker can also observe the scale (54) on the surface of the plastering template (5), and can adjust the device vertically, thereby adjusting the distance between the plastering scraper (7) and the surface of the block, so as to achieve plastering layers of different thicknesses and uniformity, meeting the construction requirements for different plastering layers.

[0046] A storage hopper (6) is respectively arranged on the upper side near the ends of the two plastering templates (5). The mortar first passes through a filter hopper (61) to filter out large particles of mortar to ensure the flatness and fullness of the mortar, and then flows along the inner wall of the storage hopper (6) and the storage hopper neck (65) into a large-volume storage box.

[0047] When the device is fixed, the worker can lift the discharge plate (56) and fix it with the fixing bolts (62), allowing the mortar to flow into the device along the discharge trough (56). After that, the worker can use the small wireless remote control (1) to start the electric wheel (2) to drive the entire device to move. In addition, a total of 12 horizontal pulleys (52) are set at the lower end of the plastering template (5) to assist in movement, making the plastering device move more easily. During the movement process, the plastering scraper (7) can spread a highly uniform mortar layer, making the filling between the blocks more dense and improving the construction quality.

[0048] In addition, the electric wheels (2) and the storage hopper (6) can save workers from frequent movement and repeated shoveling of mortar. By using a small wireless remote control, the plastering device can be moved along the plastering route, which saves workers' physical strength and improves the efficiency of plastering construction.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
