[0031] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figure 1-6 As shown, a mortar spraying device for construction includes a liquid storage component, a spray pipe 103, and a trolley 102. The liquid storage component is used to store mortar; the spray pipe 103 is connected to the liquid storage component to spray the mortar from the liquid storage component; the trolley 102 is used to load the liquid storage component and move it. Specifically, the liquid storage component includes an inner shell 110, an outer shell 101, a cover plate 104, a stirring shaft 111, a scraper 113, brush bristles 132, and an electric actuator 106; the outer shell 101 is mounted on the trolley 102; the inner shell 110 is located inside the outer shell 101; the cover plate 104 covers the inner shell 110; the stirring shaft 111 is located inside the inner shell 110; the scraper 113 and brush bristles... 132 is connected to the stirring shaft 111; the electric actuator 106 drives the scraper 113 and brush 132 to move relative to the stirring shaft 111; more specifically, the liquid storage assembly has a storage state in which the scraper 113 and brush 132 are in the middle of the inner shell 110 and a cleaning state in which the scraper 113 and brush 132 are in contact with the inner shell 110; when the liquid storage assembly is in the cleaning state, the stirring shaft 111 rotates clockwise and the scraper 113 contacts the inner wall of the inner shell 110; the stirring shaft 111 vibrates counterclockwise and the brush 132 contacts the inner wall of the inner shell 110.

[0033] When the stirring shaft 111 rotates clockwise, the scraper 113, driven by the rotating roller 130, scrapes along the inner wall of the inner shell 110, removing most of the mortar adhering to the inner wall and preventing it from solidifying due to prolonged adhesion. When the stirring shaft 111 vibrates counterclockwise, the brush bristles 132 contact the inner wall of the inner shell 110, further cleaning the inner wall and removing some fine residual mortar that the scraper 113 failed to remove. The dual cleaning method of the scraper 113 and the brush bristles 132 effectively improves the cleaning effect of the inner shell 110. Using the stirring shaft 111 to clean the inner shell 110 allows for quick cleaning without the need for other cleaning tools, making the cleaning of the inner shell 110 more convenient.

[0034] Furthermore, the liquid storage assembly also includes a first movable rod 112 and a second movable rod 114. The first movable rod 112 is connected to one side of the stirring shaft 111; the second movable rod 114 is connected to the other side of the stirring shaft 111; the second movable rod 114 is located below the first movable rod 112, and two sets of scrapers 113 and brush bristles 132 are respectively provided on the first movable rod 112 and the second movable rod 114.

[0035] This design allows for cleaning operations by the scraper 113 and brush 132 at different heights when cleaning the inner casing 110, expanding the cleaning range and improving cleaning efficiency. The connection method between the first movable rod 112 and the second movable rod 114 and the stirring shaft 111 ensures that they can move synchronously with the rotation and vibration of the stirring shaft 111, better realizing the cleaning function.

[0036] As the stirring shaft 111 rotates clockwise, driving the scraper 113 to remove mortar, the scrapers 113 on the first movable rod 112 and the second movable rod 114 can simultaneously act on different heights of the inner wall of the inner shell 110, increasing the scraping area and force. When the stirring shaft 111 vibrates counterclockwise, the brush bristles 132 can also perform a thorough cleaning of the inner wall at different heights, ensuring that every part of the inner wall of the inner shell 110 is effectively cleaned.

[0037] Furthermore, the first movable rod 112 is provided with a first mounting groove, and a rotating roller 130 and a mounting plate 131 are provided in the first mounting groove. The rotating roller 130 and the mounting plate 131 are driven together. The transmission method between the rotating roller 130 and the mounting plate 131 is the same as the transmission method of a gear and rack. The scraper 113 is provided on the rotating roller 130, and the bristles 132 are provided on the mounting plate 131. A support block 133 is provided on the inner wall of the first mounting groove. The scraper 113 abuts against the support block 133, so that the scraper 113 can only rotate in one direction.

[0038] The transmission mechanism between the roller 130 and the mounting plate 131 enables the scraper 113 and the brush 132 to work together. When the stirring shaft 111 rotates clockwise, the scraper 113 is pressed against the support block 133 and cannot rotate. One end of the scraper 113 moves along the inner wall of the inner shell 110, scraping off large pieces of mortar. When the stirring shaft 111 rotates counterclockwise, the scraper 113 rotates out of the first mounting groove due to resistance. The roller 130 and the mounting plate 131 work together to drive the mounting plate 131 to move out of the first mounting groove. The brush 132 extends out of the first mounting groove and contacts the inner wall of the inner shell 110. The brush 132 rotates with the stirring shaft 111 to clean up any remaining fine mortar.

[0039] During the scraping process of the scraper 113, due to the uneven distribution of mortar on the inner wall of the inner housing 110, the scraper 113 may experience varying degrees of resistance. This resistance is transmitted to the mounting plate 131 through the rotating roller 130, causing the mounting plate 131 to vibrate and shift slightly, thereby enabling the bristles 132 to better adapt to the condition of the inner wall and improve the cleaning effect.

[0040] Meanwhile, the mounting method of the roller 130 and the mounting plate 131 within the first mounting groove ensures their stability. The inner wall of the first mounting groove provides a certain limiting effect on the roller 130 and the mounting plate 131, preventing them from deviating too much during movement.

[0041] In practical use, as construction progresses, the mortar in the liquid storage component is continuously used and replenished. When it is necessary to clean the inner shell 110, by controlling the rotation and vibration of the stirring shaft 111, and utilizing the synergistic action of the rotating roller 130 and the scraper 113 and brush 132 on the mounting plate 131, the residual mortar on the inner wall of the inner shell 110 can be effectively cleaned, preventing the mortar from solidifying and clogging the device, thus ensuring the normal use and high efficiency of the building mortar spraying device.

[0042] The scraper 113 is a perforated plate. This perforated design allows some mortar to pass through the holes during the scraping process, reducing the resistance between the scraper 113 and the inner wall, making the scraping action smoother. At the same time, the perforated structure increases the contact area between the scraper 113 and the mortar, improving the scraping effect. When the scraper 113 moves, some mortar enters the holes. As the scraper 113 moves, this mortar creates pressure within the holes. When the pressure reaches a certain level, it washes away stubborn mortar adhering to the inner wall, further enhancing the cleaning effect.

[0043] When the stirring shaft 111 vibrates counterclockwise, driving the brush bristles 132 to clean, any residual mortar in the holes of the scraper 113 will also fall off under the vibration, preventing mortar from accumulating on the scraper 113. Furthermore, the porous design of the scraper 113 reduces its weight, lowering the load on the stirring shaft 111 during rotation and allowing the stirring shaft 111 to operate more stably. During long-term use, the porous structure of the scraper 113 also facilitates cleaning, quickly removing residual mortar from the holes and ensuring the continued effective use of the scraper 113.

[0044] As construction progresses, the mortar spraying device continuously sprays mortar and cleans the inner casing 110. During each cleaning process, the porous design of the scraper 113 and the synergistic effect of the brush 132 effectively keep the inner wall of the casing 110 clean, reducing mortar residue and hardening issues, thus significantly improving the device's lifespan and working efficiency. Simultaneously, this design reduces maintenance difficulty and costs for operators, allowing construction to proceed more smoothly.

[0045] Furthermore, the stirring shaft 111 is provided with a first connecting groove, and a first connecting rod 115 is rotatably connected in the first connecting groove. The other end of the first connecting rod 115 is rotatably connected to the first movable rod 112. The stirring shaft 111 is provided with a first guide rod 122, and the first movable rod 112 is provided with a second guide rod 123. The first guide rod 122 is provided with a first guide groove for the second guide rod 123 to move.

[0046] The bottom of the stirring shaft 111 is provided with a first movable groove, and a third movable rod 119 is provided in the first movable groove. A limiting plate 120 is provided at the top of the third movable rod 119, and a first spring 121 is provided on the limiting plate 120. A connecting block is provided at the bottom of the third movable rod 119, and a third guide rod 124 is provided on the connecting block. A fourth guide rod 125 is provided on the second movable rod 114, and a second guide groove is provided on the third guide rod 124 for the fourth guide rod 125 to move.

[0047] The stirring shaft 111 is provided with a second connecting groove, and a second connecting rod 116 is rotatably connected in the second connecting groove. The other end of the second connecting rod 116 is rotatably connected to a third connecting rod 117. A slider is provided on the second movable rod 114, and a groove for the slider to move is provided on the third connecting rod 117.

[0048] The stirring shaft 111 is provided with a transmission cavity that communicates with the first connecting groove and the second connecting groove. The transmission cavity is provided with a transmission block 126 that is in transmission cooperation with the first connecting rod 115 and the second connecting rod 116. The bottom of the transmission cavity is provided with a through cavity that communicates with the first movable groove. The transmission block 126 is provided with a third movable groove. The third movable groove is provided with a push rod 127. One end of the push rod 127 is provided with a second spring 128. One end of the second spring 128 is fixed to the inner wall of the third movable groove.

[0049] When mixing mortar, the third movable rod 119 is in the raised state, and the first connecting rod 115 and the second connecting rod 116 are both in the inclined state. The scraper 113 does not contact the inner wall of the inner shell 110, reducing the resistance encountered when the mixing shaft 111 rotates, so as to better mix the mortar. When cleaning the inside of the inner shell 110, the electric push rod 106 pushes the transmission block 126 to move, and the push rod 127 moves with the transmission block 126. When the transmission block 126 has not moved to one side of the first connecting rod 115 and the second connecting rod 116, the push rod 127 moves with the transmission block 126. Push rod 127 pushes the limiting plate 120 to move, and the third movable rod 119 extends out from the first movable groove. The third movable rod 119 drives the third guide rod 124 and the fourth guide rod 125 to move downward until the third guide rod 124, the fourth guide rod 125 and the third movable rod 119 abut against the bottom surface of the inner shell 110. At this time, push rod 127 can no longer push the third movable rod 119 to move. When the transmission block 126 moves to the side of the first connecting rod 115 and the second connecting rod 116, it interacts with the first connecting rod 115 and the second connecting rod 116. 16 forms a transmission engagement. The movement of the transmission block 126 drives the first connecting rod 115 and the second connecting rod 116 to rotate. The push rod 127 moves into the third movable groove, compressing the second spring 128, causing the transmission block 126 to move relative to the push rod 127. The rotation of the first connecting rod 115 and the second connecting rod 116 pushes the first movable rod 112 and the second movable rod 114 to move towards the inner wall of the inner housing 110. The scraper 113 abuts against the inner wall of the inner housing 110. The first guide rod 122, the second guide rod 123, the third guide rod 124, and the fourth guide rod... The setting of the guide rod 125 allows the first movable rod 112 and the second movable rod 114 to move smoothly. The third guide rod 124 and the fourth guide rod 125 abut against the bottom surface of the inner shell 110. When the stirring shaft 111 rotates, it drives the scraper 113, the third guide rod 124 and the fourth guide rod 125 to contact the inner wall and bottom surface of the inner shell 110. The scraper 113, the third guide rod 124 and the fourth guide rod 125 are used to clean the inner wall and bottom surface of the inner shell 110, reducing the cleaning dead corners in the inner shell 110 and improving the cleaning effect of the inner shell 110.

[0050] Furthermore, the second guide rod 123 is provided with a first protrusion, the first protrusion is provided with a fourth movable groove, the second guide rod 123 is provided with a fifth movable groove communicating with the fourth movable groove, the fourth movable groove is provided with a transmission rod 134, the transmission rod 134 is in transmission cooperation with the rotating roller 130; the transmission rod 134 is provided with an extension rod 135, the extension rod 135 extends out from the fifth movable groove, the extension rod 135 is provided with a third spring 136, one end of the third spring 136 abuts against the inner wall of the fifth movable groove.

[0051] The mounting plate 131 is provided with a second protrusion, and the second protrusion is provided with a fifth guide rod 137. The inner wall of the first mounting groove is provided with a third guide groove for the fifth guide rod 137 to move. The side wall of the third guide groove is provided with a sixth movable groove, and the sixth movable groove is provided with a movable block 139. The movable block 139 is provided with a seventh movable groove, and the seventh movable groove is provided with a fixed block 140. The fixed block 140 is provided with a fourth spring 141, one end of which is fixed to the inner wall of the seventh movable groove. The fifth guide rod 137 is provided with multiple fixing grooves 138 corresponding to the fixed block 140. The side wall of the fixed block 140 is provided with an inclined surface.

[0052] The movable block 139 is provided with a fifth spring 142, one end of which is fixed to the top of the sixth movable groove; the bottom of the fourth movable groove is provided with a slot communicating with the sixth movable groove; the transmission rod 134 is provided with a push block 146, and the bottom of the push block 146 is provided with an arc surface.

[0053] When the scraper 113 on the first movable rod 112 abuts against the inner wall of the inner housing 110, the second guide rod 123 extends from the first guide groove, the third spring 136 pushes the extension rod 135 to extend from the fifth movable groove, the transmission rod 134 moves into the fourth movable groove, driving the push block 146 to move into the slot, the push block 146 moves to the top of the movable block 139, pushing the movable block 139 to move out of the sixth movable groove, and the fixed block 140 abuts against the fifth guide rod 137 and enters the seventh movable groove; when the stirring shaft 111 drives the first movable rod 112... 2. When the second movable rod 114 rotates counterclockwise, the scraper 113 is resisted and drives the rotating roller 130 to rotate. The rotating roller 130 drives the mounting plate 131 to move, causing the mounting plate 131 to move out of the first mounting groove. The mounting plate 131 drives the fifth guide rod 137 to move, causing the fixing groove 138 to move to the position of the fixing block 140. The fixing block 140 is inserted into the fixing groove 138. The fixing block 140 provides support for the mounting plate 131, so that the bristles 132 are always in the extended state, which is convenient for cleaning the inner wall of the inner shell 110.

[0054] The piston rod of the electric actuator 106 is fixed to the transmission block 126. After the inner housing 110 is cleaned, the electric actuator 106 drives the transmission block 126 to move upward. The transmission block 126 drives the first connecting rod 115 and the second connecting rod 116 to rotate in opposite directions. The first movable rod 112 and the second movable rod 114 are reset. The second guide rod 123 moves into the first guide groove. The extension rod 135 abuts against the inner wall of the first guide groove and moves into the fifth movable groove. The push block 146 moves out of the slot, causing the push block 146 to move out of the slot. 6 is offset from the movable block 139. The fifth spring 142 pulls the movable block 139 to move into the sixth movable groove, and the fixed block 140 moves out of the fixed groove 138. When the transmission rod 134 moves to the rotating roller 130, it forms a transmission engagement with the rotating roller 130. The movement of the transmission rod 134 drives the rotating roller 130 to rotate. The rotating roller 130 drives the mounting plate 131 to move, so that the scraper 113 rotates back to the position of the support block 133, and the bristles 132 are stored in the first mounting groove to protect the bristles 132.

[0055] The structures of the third guide rod 124 and the fourth guide rod 125 are the same as those of the first guide rod 122 and the second guide rod 123.

[0056] The cover plate 104 is provided with a first mounting bracket 105 and a second mounting bracket 107. The electric push rod 106 is provided on the first mounting bracket 105. The second mounting bracket 107 is provided with a first motor 108. The output shaft of the first motor 108 is provided with a first transmission wheel 109. One end of the stirring shaft 111 passes through the cover plate 104 and forms a transmission engagement with the first transmission wheel 109. The first motor 108 provides rotational power to the stirring shaft 111.

[0057] The inner housing 110 is provided with a support ring 129 at the top, which facilitates the removal of the inner housing 110. The outer housing 101 is provided with a support plate 143 on its side wall, and a second motor 144 is provided on the support plate 143. A second transmission wheel 145 is provided on the output shaft of the second motor 144.

[0058] The second motor 144 drives the second transmission wheel 145 to rotate, thereby causing the inner shell 110 to rotate within the outer shell 101. This rotating design of the inner shell 110 further improves the uniformity of mixing during mortar mixing. When the inner shell 110 rotates, the mortar inside flows in the direction of rotation, cooperating with the mixing action of the mixing shaft 111 to ensure that all parts of the mortar are fully mixed, avoiding uneven local mortar concentration.

[0059] When cleaning the inner shell 110, the rotation of the inner shell 110 also enhances the cleaning effect of the scraper 113 and brush 132. The rotation of the inner shell 110, combined with the rotation and vibration of the stirring shaft 111, allows the scraper 113 and brush 132 to clean the inner wall of the inner shell 110 from different angles and directions, further reducing cleaning dead corners. The scraper 113 and brush 132 can more comprehensively contact all parts of the inner wall of the inner shell 110, removing residual mortar more thoroughly.

[0060] At the same time, this design also increases the flexibility and adaptability of the device. In different construction scenarios, the rotation speed of the inner shell 110 and the rotation and vibration frequency of the mixing shaft 111 can be flexibly adjusted according to the characteristics of the mortar and the usage requirements to achieve the best mixing and cleaning effect.

[0061] The bottom of the outer shell 101 is provided with a turntable 118, and the inner shell 110 is located on the turntable 118 to reduce the friction when the inner shell 110 rotates. The bottom of the inner shell 110 is provided with a liquid outlet, and the turntable 118 is provided with a through cavity that communicates with the liquid outlet. The nozzle 103 is connected to the through cavity, and the mortar in the inner shell 110 is sprayed out from the nozzle 103 through the pump body.
