Description

Technical Field

[0001] This utility model belongs to the field of control device technology, specifically, it relates to a wall plastering device for building engineering. Background Technology

[0002] In traditional wall plastering operations in building construction, manual labor using tools such as trowels is the main method. However, with the continuous development of the construction industry and the increasing scale of buildings, high-rise buildings, large commercial complexes, and other construction projects are emerging, which place higher demands on the efficiency and quality of wall plastering.

[0003] Chinese patent CN212957490U discloses a wall plastering device for building construction. When the plastering machine is applying lime mortar to the wall, a fan is activated to create negative pressure on one side of the wall. The freshly plastered wall emits a strong, pungent odor. The fan draws the pungent and harmful substances into the air guide housing, where activated carbon plates attached to the storage box absorb a large amount of the pungent and harmful substances, achieving rapid absorption and shortening the move-in time. However, in actual use, when the plastering machine moves vertically up and down on the lifting rod for plastering, uneven plastering may occur due to factors such as the stability of the lifting rod, vibration of the plastering machine itself, or unevenness of the wall surface.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a wall plastering device for building engineering, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A wall plastering device for building construction includes: an outer shell, a feed inlet connected to the top of the outer shell, a mortar tank connected inside the outer shell, the mortar tank being connected to the bottom of the feed inlet, a first connecting pipe connected to the side wall of the mortar tank, a second connecting pipe connected to the other outlet of the first connecting pipe, a third connecting pipe connected to the other outlet of the second connecting pipe, the third connecting pipe being connected to a nozzle via a movable component, a mortar pump connected in the middle of the first connecting pipe, a flow controller connected between the first connecting pipe and the second connecting pipe, a pressure sensor connected at the connection between the third connecting pipe and the second connecting pipe, and a heat dissipation vent provided on the surface of the outer shell corresponding to the mortar pump.

[0008] Optionally, the flow controller is connected to a control valve core at its bottom end. The control valve core is embedded inside the first connecting pipe and is rotatably connected to the first connecting pipe.

[0009] Optionally, the control valve core is spherical and has a through hole in the middle, the diameter of which is the same as the diameter of the inner opening of the first connecting pipe.

[0010] Optionally, the second connecting pipe is tapered, with the smaller diameter end connecting to the third connecting pipe.

[0011] Optionally, the movable part is spherical and rotatably connected to the nozzle, and the movable part has an opening inside.

[0012] Optionally, the nozzle has an internal baffle that divides it into two identical channels.

[0013] Optionally, the nozzle outlet end is connected to an atomizing plate, and the surface of the atomizing plate has multiple through holes, which are conical in shape.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] The flow controller precisely adjusts the mortar flow by controlling the rotation of the valve core, ensuring that the amount of mortar sprayed from the nozzle meets the requirements and avoiding uneven plaster thickness caused by unstable mortar flow. At the same time, the baffle inside the nozzle divides it into two identical channels, allowing the mortar to be evenly distributed within the nozzle. In addition, the atomizing plate at the outlet further refines, disperses, and evenly adheres the mortar to the wall, making the plaster layer more uniform in thickness and texture, thus improving the overall quality of plastering.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown in the figure, this embodiment provides a wall plastering device for building engineering, including: a shell 1, a feed inlet 2 connected to the top of the shell 1, a mortar box 3 connected inside the shell 1, the mortar box 3 being connected to the bottom of the feed inlet 2, a first connecting pipe 5 connected to the side wall of the mortar box 3, a second connecting pipe 10 connected to the other outlet end of the first connecting pipe 5, a third connecting pipe 11 connected to the other outlet end of the second connecting pipe 10, the third connecting pipe 11 being connected to a nozzle 8 via a movable part 13, a mortar pump 4 connected in the middle of the first connecting pipe 5, a flow controller 6 connected between the first connecting pipe 5 and the mortar pump 4 and the second connecting pipe 10, a pressure sensor 7 connected at the connection point between the third connecting pipe 11 and the second connecting pipe 10, and a heat dissipation vent 9 opened on the surface of the shell 1 corresponding to the mortar pump 4.

[0027] The outer shell 1, as the external structure of the entire plastering device, protects the internal components and provides overall support. The inlet 2 is located at the top of the outer shell 1. By placing the inlet 2 at a high position, the mortar can flow smoothly into the mortar tank 3 connected to it below under the action of gravity. The mortar tank 3 is located inside the outer shell 1 and is connected to the bottom of the inlet 2. It is mainly used to store mortar to be used. When the mortar pump 4 is working, it can provide power for the flow of mortar, causing the mortar to be sucked out of the mortar tank 3 and flow along the first connecting pipe 5 to the subsequent pipes. The second connecting pipe 10 plays a connecting role. It works with the first connecting pipe 5 and the third connecting pipe 11 to form a mortar conveying channel from the mortar tank 3 to the nozzle 8, so that the mortar can flow smoothly to the final spraying position. The third connecting pipe 11 is the last section of the conveying pipe before the mortar reaches the nozzle 8. Through the design of the movable part 13 connecting to the nozzle 8, the nozzle 8 can be adjusted according to the actual situation. To meet the specific plastering needs, the angle and position can be flexibly adjusted within a certain range, facilitating plastering operations on walls at different angles and locations. The flow controller 6 is connected to the first connecting pipe 5, which can precisely control the flow rate of mortar in the pipe. During the plastering process, a stable and appropriate mortar flow rate is required based on different wall plastering requirements, construction speed, and other factors. The flow controller 6 can monitor and adjust the mortar flow rate in real time to ensure that the amount of mortar sprayed from the nozzle 8 meets the uniformity and quality requirements of plastering. The pressure sensor 7 is responsible for real-time monitoring of the pressure in the pipe before the mortar reaches the nozzle 8. Since the mortar spraying effect (such as spraying distance, uniformity, etc.) is closely related to the pressure, the pressure data continuously fed back by the pressure sensor 7 can, on the one hand, determine whether the entire mortar delivery system is working properly, and on the other hand, provide a basis for adjusting related components such as the flow controller 6 and the mortar pump 4, ensuring the stable progress of the plastering operation.

[0028] In this embodiment, the bottom end of the flow controller 6 is connected to a control valve core 12, which is embedded inside the first connecting pipe 5 and rotatably connected to it. The control valve core 12 is spherical and has a through hole in the middle, which has the same diameter as the internal opening of the first connecting pipe 5. The second connecting pipe 10 is conical, and the end connected to the third connecting pipe 11 has a smaller diameter. The movable part 13 is spherical and rotatably connected to the nozzle 8. The movable part 13 has an internal opening. The nozzle 8 is connected to a partition 15, which divides the nozzle into two identical channels. The outlet end of the nozzle 8 is connected to an atomizing plate 14, which has multiple through holes on its surface, and these through holes are conical.

[0029] The control valve core 12, connected to the bottom of the flow controller 6, is embedded inside the first connecting pipe 5 and is rotatably connected to it, allowing the control valve core 12 to rotate flexibly within the first connecting pipe 5, thereby achieving flow regulation. The flow controller 6 drives the rotation of the control valve core 12 to change its state within the pipe, thus regulating the mortar flow rate. The spherical structure ensures that the valve core experiences more uniform force during rotation, resulting in smoother rotation and easier sealing. A central opening allows the mortar to flow through the pipe at maximum flow rate when it is fully aligned with the internal opening of the first connecting pipe 5. When the control valve core 12 rotates, causing partial overlap or misalignment between the opening and the internal opening of the first connecting pipe 5, the effective cross-sectional area through which the mortar can pass changes, thus achieving precise regulation of the mortar flow rate. The second connecting pipe 10 is conical, with the smaller diameter end connecting to the third connecting pipe 11. The conical structure is designed based on fluid mechanics principles, guiding and accelerating the mortar flow. The mortar flows in from the end with a relatively large diameter. As the pipe diameter gradually decreases, the flow rate of the mortar gradually increases. This ensures that the mortar has a suitable flow velocity before flowing to the nozzle, which helps to ensure better power and spraying effect when the mortar is sprayed out. This makes the plastering work more uniform and smooth. The spherical moving part can rotate in multiple directions, allowing the connected nozzle to flexibly adjust its angle and position according to the actual plastering needs. The baffle divides the inside of the nozzle into two identical channels, allowing the mortar to be distributed more evenly inside the nozzle, avoiding local flow rates that are too fast or too slow, or uneven flow. The surface of the atomizing plate has multiple cone-shaped through holes. When the mortar is sprayed out through these cone-shaped through holes, the shape of the through holes will further refine and disperse the mortar during the spraying process, forming a mist-like effect. The atomized mortar can adhere to the wall more finely and evenly, which not only makes the plaster layer smoother and more even, but also improves the adhesion between the mortar and the wall, reducing the possibility of quality problems such as hollowing and cracking.

[0030] Working principle:

[0031] First, the operator pours mortar into the device through the inlet located at the top of the casing. After the plastering device is started, the mortar pump installed in the middle of the first connecting pipe begins to work, sucking out the mortar in the mortar tank and causing the mortar to flow along the first connecting pipe to the subsequent pipes. Then, it enters the nozzle through the second and third connecting pipes. An atomizing plate is connected to the nozzle outlet, and its surface has multiple conical through holes. When the mortar reaches the outlet through the internal channel of the nozzle and is sprayed out through these conical through holes, due to the shape characteristics of the through holes, the mortar will be further refined and dispersed during the spraying process, forming a similar atomization effect. The atomized mortar has a finer and more uniform texture, which can better adhere to the wall. This not only makes the plaster layer surface smoother and more even, but also enhances the adhesion between the mortar and the wall, effectively reducing the possibility of quality problems such as hollowing and cracking of the plaster layer, and ultimately achieving high-quality wall plastering.

[0032] During use, if the pressure sensor detects that the pressure is too low, the control system can instruct the mortar pump to increase its speed to increase the pressure, or increase the flow rate by appropriately widening the inlet through the flow controller to increase the pressure, so as to ensure that the plastering operation is stable and normal.

[0033] When constructing walls with a thinner plaster layer, the flow controller drives the control valve core to rotate, causing the openings to be staggered and reducing the mortar flow; while for walls requiring a thicker plaster layer, the openings are aligned more closely to increase the flow.
