Description

Technical Field

[0001] This invention relates to a plunger-type automatic spraying and leveling device for exterior wall mortar, belonging to the technical field of building decoration construction machinery and devices. Background Technology

[0002] Currently, after the walls are constructed, cement mortar needs to be applied to the surface to enhance their support, insulation, and decorative functions. This mortar application is currently mostly done manually, requiring scaffolding for work at heights. This wastes steel pipes and timber, poses safety hazards, and is inefficient and labor-intensive. Furthermore, manual plastering can lead to defects such as hollow areas on the building surface. To overcome these drawbacks, traditional mortar spraying machines are now commonly used on construction sites for mechanized mortar application. These machines deliver pre-mixed mortar through a pipeline, and the nozzles use negative air pressure to spray the mortar onto the target surface, such as a wall, forming a protective mortar layer. Mechanized mortar spraying has changed the traditional manual plastering method, improving both construction efficiency and quality. The current problem with traditional spray guns is that most thermal insulation mortar particles are uneven in size and contain functional particles such as short fibers, which can easily cause blockages during the spraying process, seriously affecting construction efficiency. In addition, spraying and smoothing need to be done twice, which further reduces construction efficiency. Summary of the Invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a plunger-type automatic spraying and leveling device for exterior wall mortar that has strong spraying force and can complete the two processes of spraying and smoothing in one construction.

[0004] To achieve the above objectives, the technical solution proposed by this invention is as follows: a plunger-type automatic spraying and leveling integrated device for exterior wall mortar, comprising a suspended basket, a base disposed within the suspended basket, and a spraying mechanism and a leveling mechanism both disposed on the base. The spraying mechanism includes a plunger-type mortar pump, with a nozzle at the front end of the plunger-type mortar pump. The leveling mechanism includes support rods disposed on the base and symmetrically arranged on both sides of the nozzle, a roller disposed between the two support rods, two baffles hinged to the upper and lower ends of the support rods, and hanging plates hinged to both sides of the two baffles. The two baffles and the two hanging plates form a quadrilateral cover, and the roller and the nozzle are both located inside the quadrilateral cover.

[0005] One end of the baffle is hinged to the support rod, and a tension spring is connected to the middle. The end of the tension spring away from the baffle is connected to the support rod, and the connection point is located above the hinge point between the baffle and the support rod.

[0006] The baffle has several hanging pieces on both sides, and the two ends of the hanging pieces are respectively hinged to the two baffles.

[0007] The support rod includes a main support rod and a secondary support rod, with the main support rod located inside the secondary support rod. The two ends of the roller are rotatably connected to the two main support rods; the baffle is hinged to the two secondary support rods.

[0008] The nozzle is provided with several nozzles arranged horizontally, and the roller is set in a direction parallel to the direction in which the nozzles are arranged.

[0009] The rollers are provided in one or more locations; when there is one roller, it is positioned above or below the nozzle; when there are multiple rollers, they are positioned on the upper and lower sides of the nozzle respectively.

[0010] The main support rod is equipped with a triangular brace. One right-angled side of the triangular brace is fixedly connected to the main support rod, and the other right-angled side is supported at the bottom of the nozzle.

[0011] The drum has a drum shaft inside, and the drum is rotatably connected to the drum shaft; each end of the drum shaft is connected to an adjusting rod, and the two adjusting rods are respectively connected to two main support rods.

[0012] The adjusting rod has a fork at the connection end with the roller shaft. The end of the roller shaft extends into the inside of the fork and is hinged to the adjusting rod by a pin. The pin is set vertically.

[0013] The main support rod has a through hole for the adjusting rod to pass through. The end of the adjusting rod away from the drum has an external thread and passes through the through hole. A nut is screwed onto the part of the adjusting rod that passes through the through hole. The nut abuts against the side of the main support rod away from the drum. A compression spring is fitted onto the end of the adjusting rod near the drum, and a stop block is provided near the drum. One end of the compression spring abuts against the stop block, and the other end abuts against the side of the main support rod near the drum.

[0014] The base is provided with a material discharge chute, which is located directly below the nozzle.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. In this invention, the spraying mechanism uses a plunger pump to spray mortar insulation material, which greatly enhances the spraying force compared with traditional air negative pressure spraying, thereby enhancing the adhesion of the mortar insulation material. This not only effectively solves the clogging problem caused by functional particles such as short fibers in the mortar, but also effectively improves the spraying quality.

[0017] 2. This invention combines a plunger-type mortar pump and a flattening mechanism with the lowering or raising of the suspended platform, which greatly improves the spraying efficiency, significantly reduces costs, and enhances the competitiveness of the project.

[0018] 3. In this invention, the upper and lower baffles can be tilted upwards and flipped downwards, so that the baffle setting direction and the movement direction can be obtuse angle when the suspended platform moves up and down. This prevents the baffle from scraping off the mortar while it is in contact with the wall. Combined with the rollers set on the upper and lower sides of the spray head, the spraying and flattening functions can be completed when the suspended platform moves up and down, further improving work efficiency.

[0019] 4. In this invention, the roller shaft is hinged to the adjusting rod, so the parallelism between the roller and the wall can be adjusted by adjusting the adjusting rod to ensure that the mortar is evenly flattened. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Example 1

[0027] like Figure 1As shown in this embodiment, an integrated automatic spraying and leveling device for exterior wall mortar using a plunger type includes a spraying mechanism and a leveling mechanism, both mounted on a base 20. The spraying mechanism includes a plunger-type mortar pump, which comprises a motor 1, a reducer 2, a crank-connecting rod mechanism 3, a hopper 4, a cylinder 5, a plunger cylinder 6, a suction valve 7, and a nozzle 8. The motor 1 is driven by the reducer 2, which is also driven by the crank-connecting rod mechanism 3. The crank-connecting rod mechanism 3 is connected to the plunger cylinder 6 and drives the plunger of the plunger cylinder 6 to reciprocate. The hopper 4 and the nozzle 8 are both connected to the plunger cylinder 6. The repeated movement of the plunger in the plunger cylinder 6 generates pressure on the mortar. After falling from the hopper, the mortar reaches the nozzle 8 under this pressure. The cylinder 5 stores the pressurized gas generated by the plunger cylinder 6, softening and buffering the pressure on the mortar. The cylinder 5 is also equipped with a 501-pressure gauge, and the plunger cylinder 6 is equipped with a suction valve 7. Figure 2 As shown, the nozzle 8 has four nozzles 9 arranged side by side at its front end.

[0028] Combination Figure 2 As shown, the flattening mechanism includes support rods mounted on the base 20 and symmetrically arranged on both sides of the nozzle 8, a roller 17 disposed between the two support rods, two baffles hinged to the upper and lower ends of the support rods, and transparent hanging plates 19 hinged to both sides of the two baffles; the support rods include main support rods 10 and auxiliary support rods 11, with the main support rod 10 located inside the auxiliary support rod 11; the roller 17 has a roller shaft 16 inside, and the roller 17 is rotatably connected to the roller shaft 16, with both ends of the roller shaft 16 rotatably connected to the two main support rods 10; the two baffles are an upper baffle 18 and a lower baffle 13, which are respectively hinged to the two auxiliary support rods 10. On the support rod 11, one end of the upper baffle 18 is hinged to the upper part of the auxiliary support rod 11 via an upper pivot 1801. An upper tension spring 1802 is connected to the middle of the upper baffle 18. The end of the upper tension spring 1802 away from the upper baffle 18 is connected to the auxiliary support rod 11, and this connection point is located above the hinge point between the upper baffle 18 and the auxiliary support rod 11. Similarly, one end of the lower baffle 13 is hinged to the lower part of the auxiliary support rod 11 via a lower pivot 1301. A lower tension spring 1302 is connected to the middle of the lower baffle 13. The end of the lower tension spring 1302 away from the lower baffle 13 is connected to the auxiliary support rod 11, and this connection point is located above the hinge point between the lower baffle 13 and the auxiliary support rod 11. Each side of the baffle has four hanging plates 19, arranged side by side. The two ends of the four hanging plates are respectively hinged to the upper and lower baffles via hanging plate shafts 1901, so that the upper and lower baffles and the hanging plates on both sides form a quadrilateral cover. The roller 17 and the nozzle 8 are both located inside the quadrilateral cover. The hanging plates 19, made of transparent material, not only work with the baffle to shield the mortar and prevent the mortar sprayed onto the exterior wall from splashing out, but also allow for easy and clear observation of the working conditions, thus protecting the environment and greatly improving the working conditions.

[0029] The main support rod 10 is provided with a triangular brace 1001. One right-angled side of the triangular brace 1001 is fixedly connected to the main support rod 10, and the other right-angled side is supported at the bottom of the nozzle 8 to support the nozzle 8.

[0030] In this embodiment, each end of the roller shaft 16 is connected to an adjusting rod 14, and the two adjusting rods 14 are respectively connected to two main support rods 10. The two adjusting rods are arranged parallel to each other. The main support rod 10 is provided with a through hole for the adjusting rod 14 to pass through. The size of the through hole matches the adjusting rod 14. The end of the adjusting rod 14 away from the roller 17 is provided with an external thread and passes through the through hole. A nut 1401 is screwed onto the part of the adjusting rod 14 that passes through the through hole. The nut 1401 abuts against the side of the main support rod 10 away from the roller 17. A compression spring 15 is sleeved on the end of the adjusting rod 14 near the roller 17. A stop block 1404 is provided near the roller. One end of the compression spring 15 abuts against the stop block 1404, and the other end abuts against the side of the main support rod 10 near the roller 17. By rotating the nut 1401, the distance between the roller 17 and the main support rod 10 can be adjusted, thereby adjusting the pressure of the roller 17 on the outer wall surface, which can better smooth and compact the mortar. The outer surface of the roller 17 is made of flexible material, which can further improve the smoothing and compaction effect, enhance the adhesion and flatness of the insulation material, and eliminate the manual smoothing process, thus improving both the spraying quality and efficiency.

[0031] Combination Figure 3 As shown, in this embodiment, both the spraying mechanism and the flattening mechanism are located in the suspended basket 21. The base 20 is located at the bottom of the suspended basket. The roller 17 extends out of the suspended basket 21 and is located above the nozzle 8. The setting direction of the roller 17 is parallel to the arrangement direction of the nozzles 9. During use, the appropriate nozzle 8 and nozzle 9 are selected according to the required spraying width of the exterior wall 22, and the parallelism and required gap between the roller 17 and the wall surface are adjusted. At this time, under the action of gravity, the upper and lower baffles are tightly attached to the wall surface at the top edge, and the two sides are closed by transparent hanging pieces to form a closed space. As the electric suspended basket 21 descends, the spraying mechanism sprays mortar while the flattening mechanism flattens the mortar, improving work efficiency. The sprayed material falls into the material drop trough 12 set on the base for collection and reuse, which protects the environment, saves materials, and saves labor costs. The material drop trough 12 is located directly below the nozzle 8. Example 2

[0032] The structure of the plunger-type automatic spraying and leveling integrated device for exterior wall mortar in this embodiment is basically the same as that in Embodiment 1. The difference is that in this embodiment, there are two rollers 17, which are arranged on the upper and lower sides of the nozzle 8. In the technical solution of Embodiment 1, since the rollers 17 are located above the nozzle 8, they can only achieve the effect of spraying and leveling simultaneously when the basket descends. At this time, the upper and lower baffles are pressed against the wall surface by their own gravity and move downward with the basket. The baffle setting direction and the direction of movement form an obtuse angle, so they are not easily blocked by the exterior wall 22 and will not scrape off the leveled mortar. However, in this embodiment, the two rollers are arranged on the upper and lower sides of the nozzle 8. When spraying mortar on the area of ​​the exterior wall, the basket 21 needs to be used to spray up and down repeatedly. The device in this embodiment can complete the spraying and leveling operations when the basket moves upward. Figure 4 As shown in the figure, only the roller below the nozzle 8 is shown. When the basket moves up, the upper and lower baffles are flipped to tilt downwards, so that the baffle setting direction and the movement direction continue to be at an obtuse angle. Under the action of the upper and lower tension springs, the upper and lower baffles remain in close contact with the wall, preventing mortar from splashing. Example 3

[0033] The structure of the plunger-type automatic spraying and leveling integrated device for exterior wall mortar in this embodiment is basically the same as that in Embodiment 1, the difference being: Figure 5 As shown, in this embodiment, the adjusting rod 14 is provided with a fork 1402 at the connection end with the roller shaft 16. The end of the roller shaft 16 is strip-shaped and extends into the inside of the fork. The end of the roller shaft 16 is hinged to the adjusting rod 14 via a pin 1403. The pin 1403 is vertically set, so that the roller shaft 16 and the adjusting rod 14 can rotate relative to each other in the horizontal plane and adjust the included angle. Since the basket 21 is used to drive the integrated spraying and flattening device to move up and down, the roller 17 and the wall surface of the outer wall 22 will inevitably have a certain angle, resulting in uneven flattening pressure. In this embodiment, the adjusting rod 14 is hinged to the roller shaft 16. Therefore, adjusting the nuts 1401 on the two adjusting rods 14 can adjust the parallelism between the roller shaft 16 and the wall surface, thereby ensuring the uniformity of flattening pressure.
