[0033] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0034] like Figures 1-5 As shown, this embodiment provides an integrated grouting and plastering construction device, mainly composed of a grout spraying and plastering mechanism 1 and a grout supply mechanism 2, wherein the grout supply mechanism 2 is responsible for supplying grout to the grout spraying and plastering mechanism 1. The grout spraying and plastering mechanism 1 includes a sprayer 1a and a plastering device 1b mounted on the sprayer 1a. The sprayer 1a is used to spray grout onto the surface to be constructed, with its nozzle facing the surface during use. The plastering device 1b is used to smooth the grout sprayed onto the surface, and its working surface is a smooth plane. The plastering device 1b can be a traditional manual plastering board or an automatic plastering board driven by a motor. The aforementioned surface to be constructed includes, but is not limited to, a wall surface. The aforementioned grout includes, but is not limited to, mortar.

[0035] like Figure 4 , 5As shown, the embodiment is internally provided with a slurry storage cavity 1a1 in the slurry sprayer 1a, the rear end of the slurry storage cavity 1a1 is provided with a feeding passage 1a2, the front end is provided with a discharging passage 1a3, and the cross-sectional area of the feeding passage 1a2 and the discharging passage 1a3 is smaller than that of the slurry storage cavity 1a1. Under the buffering effect of the slurry storage cavity 1a1, the fluctuation of the slurry discharging speed caused by the unstable feeding speed can be reduced, and uniform slurry discharging can be realized. This uniform slurry discharging characteristic can reduce the waste of slurry caused by uneven slurry discharging, make the slurry form a uniform initial distribution on the surface to be constructed, reduce the time and effort of workers to adjust the slurry distribution, reduce the difficulty of troweling, and improve the working efficiency and quality of troweling. In addition, the front end of the discharging passage 1a3 is the slurry spraying port of the slurry sprayer 1a. The cross-sectional shape of the feeding passage 1a2 and the discharging passage 1a3 includes but is not limited to rectangular, trapezoidal, circular, and elliptical.

[0036] Generally, the discharging passage 1a3 of the slurry sprayer 1a can be arranged at the upper end, middle or lower end of the front wall of the slurry storage cavity 1a1. In order to further stabilize the flow rate of the sprayed slurry, the embodiment arranges the discharging passage 1a3 of the slurry sprayer 1a at the upper end of the front wall of the slurry storage cavity 1a1, which can be seen from Figure 5 This arrangement has two effects. First, the slurry storage cavity 1a1 acts as a temporary storage and buffering space. Since the slurry needs to fill the slurry storage cavity 1a1 first before being discharged from the upper end of the discharging passage 1a3, even if the discharging speed of the slurry feeding mechanism 2 fluctuates during the spraying process, the slurry storage cavity 1a1 can stabilize the flow rate of the slurry discharged from the discharging passage 1a3 to a certain extent, effectively avoiding the instability of the flow rate of the sprayed slurry caused by the instantaneous change of the feeding speed, and further ensuring the uniformity of the spraying quality. Second, in the slurry storage cavity 1a1, the slurry can be mixed to a certain extent. When new slurry enters the slurry storage cavity 1a1, it will interact with the existing slurry in the cavity, promoting the more uniform mixing of slurry from different batches or different parts.

[0037] Generally, the bottom surface of the slurry storage cavity 1a1 can be arranged as a horizontal surface, but in order to promote the flow of the slurry, the embodiment arranges the bottom surface of the slurry storage cavity 1a1 as an inclined surface. Specifically, as shown in Figure 5 the bottom surface of the slurry storage cavity 1a1 gradually inclines downward from the feeding end to the discharging end, thereby forming a low-lying area at one end close to the discharging end. The low-lying area formed by the inclined bottom surface enables the slurry to flow naturally toward the discharging end under the action of gravity, and the inclined bottom surface and the low-lying area can provide a directional flow path for the slurry, enabling the slurry to flow more quickly and smoothly from the feeding end to the discharging end, reducing the residence time of the slurry in the slurry storage cavity 1a1, and further improving the working efficiency of the slurry sprayer 1a.

[0038] The slurry application and smearing integrated construction device of the embodiment, the smearing operation thereof depends on the user to complete by hand-holding the sprayer 1a and the smearing device 1b. In order to facilitate the user to take, the holding handle 1c is installed at the upper end of the sprayer 1a, and the recess 1c1 which can be matched with the habit of holding fingers is arranged at the front end of the holding handle 1c, which can be seen in Figures 3-5 . In this way, the user can realize easy and stable holding and keep comfortable holding experience in long-time operation by means of the holding handle 1c with the recess 1c1 in the operation process, which significantly improves the convenience and comfort of operation. In addition, the smearing device 1b can be fixedly installed on the sprayer 1a through the connecting rods on both sides, which ensures the relative position between the smearing device 1b and the sprayer 1a to be stable.

[0039] In the embodiment, the smearing device 1b is arranged above the sprayer 1a and is fixedly connected with the sprayer 1a and can move synchronously. In order to avoid the interference of the sprayer 1a on the smearing work of the smearing device 1b, the working surface of the smearing device 1b is arranged to be aligned with the discharge end surface of the sprayer 1a, or the working surface of the smearing device 1b is arranged to be a certain distance beyond the discharge end surface of the sprayer 1a. When the user sprays the slurry by hand-holding the sprayer 1a, the smearing device 1b can smear the just sprayed slurry immediately due to the synchronous movement of the smearing device 1b and the sprayer 1a, which achieves the effect of immediate smearing and improves the work efficiency.

[0040] The slurry feeding mechanism 2 of the embodiment comprises a hopper 2a and a screw feeding device 2b. The screw feeding device 2b is installed below the hopper 2a, and the discharge end of the screw feeding device 2b is connected with the feeding end (feeding channel 1a2) of the sprayer 1a through the pipeline 3 (such as a hose). The screw feeding device 2b comprises a sleeve 2b1 and a screw feeding shaft 2b2 arranged in the sleeve 2b1, and the screw feeding shaft 2b2 is connected with a driving part 2b3 (such as a motor) for driving the rotation of the screw feeding shaft 2b2, which can be seen in Figure 2The lower end of the hopper 2a is communicated with the sleeve 2b1, so that the slurry can fall into the effective coverage area of the screw feeding shaft 2b2 to realize material conveying. In order to improve the stability of the screw feeding shaft 2b2, a plurality of (for example, two) fixed seats are arranged at intervals on the end connected with the motor. Each fixed seat is provided with a bearing, and the screw feeding shaft 2b2 is installed on the bearings. At the same time, the installation area should avoid the material as much as possible to prevent the material from damaging the related parts. Of course, the fixed seat and the bearing can also be installed on the other end of the screw feeding shaft 2b2, and the discharge hole penetrating through both sides is arranged on the fixed seat to ensure the normal output of the material. The screw feeding device 2b can realize continuous and stable feeding, avoid the intermittence of material supply, and ensure the continuity and stability of the gunning operation. In addition, the structure and principle of the screw feeding device 2b are similar to those of the existing screw feeding equipment, and therefore will not be described in detail here. Of course, the screw feeding device 2b can also be replaced by other devices capable of conveying materials, such as a driving pump.

[0041] In addition, as shown in Figure 1 、 2 The slurry feeding mechanism 2 also comprises a rack 2c, and the hopper 2a and the screw feeding device 2b and other components are installed on the rack 2c. The bottom of the rack 2c is provided with traveling wheels 2d, which can facilitate the movement of the device. The rack 2c is also provided with a push rod 2e, which can facilitate the movement of the device by workers. In addition, the rack 2c is also provided with some auxiliary components, such as a power storage device and a speed controller. The power storage device is used to supply power to the electrical components in the device, and the speed controller is used to control the feeding speed of the screw feeding device 2b.

[0042] In use, the slurry is poured into the hopper 2a, and the slurry falls along the hopper 2a into the working area (the coverage area of the screw feeding shaft 2b2) of the screw feeding device 2b, and then the screw feeding device 2b is controlled to drive the screw feeding shaft 2b2 to rotate for feeding, and the slurry is conveyed to the gunning machine 1a through the pipeline 3. The worker holds the trowel 1b fixedly connected with the gunning machine 1a as a whole, and directs the gunning machine 1a towards the surface to be constructed. The gunning machine 1a uniformly sprays the slurry onto the surface to be constructed, and the trowel 1b synchronously performs the troweling work on the just sprayed slurry, so that the whole construction process is completed in one go. The gunning and troweling operations are carried out simultaneously, which can reduce the waiting time between construction procedures and improve the construction efficiency.

[0043] The side (such as the side or the bottom) of the gun 1a is provided with a detachable baffle 4, and one side of the slurry storage cavity 1a1 is open. The baffle 4 is used to seal the slurry storage cavity 1a1, so that the cleaning work of the slurry storage cavity 1a1 is facilitated. After the slurry is used up, the baffle 4 is removed, and the inside of the slurry storage cavity 1a1 can be directly cleaned, and the residual slurry can be timely removed. This can avoid the slurry from being attached to the inner wall for a long time and being dried and caked, and reduce the risk of caking caused by mixing of new slurry and residual dried slurry during subsequent use.

[0044] In the embodiment, as shown in Figures 3-5 , the lower side of the slurry storage cavity 1a1 is open, and the baffle 4 is arranged at the bottom of the gun 1a and serves as the bottom wall of the slurry storage cavity 1a1. The baffle 4 serving as the bottom wall of the slurry storage cavity 1a1 can close the bottom of the slurry storage cavity 1a1 and prevent the slurry from leaking from the bottom. In terms of cleaning work, a large amount of slurry is usually left at the bottom of the slurry storage cavity 1a1 after use. Since the baffle 4 serves as the bottom wall, once it is removed, the bottom of the slurry storage cavity 1a1 is exposed, and the workers can quickly clean the slurry at the bottom of the slurry storage cavity 1a1, thereby improving the cleaning efficiency.

[0045] The baffle 4 can be fixed on the gun 1a by screws (such as quick-release screws) or other fasteners to facilitate disassembly. Of course, the baffle 4 can also be fixed on the gun 1a by a limiting mechanism to meet different use requirements. Specifically, as shown in Figures 3-5 , a strip-shaped limiting sliding groove 1a4 is arranged on the gun 1a (such as along the left-right direction), and one end of the sliding groove is open and the other end is closed. When the baffle 4 is installed, it can be put into the limiting sliding groove 1a4 from the open end, and the closed end can block the baffle 4 after it is slid in, effectively preventing the baffle 4 from moving excessively and ensuring the stability of the position of the baffle 4 in the limiting sliding groove 1a4. At the same time, limiting parts 4a corresponding to the baffle 4, such as strip-shaped protrusions or limiting columns, are arranged at both ends of the baffle 4. The strip-shaped protrusions or limiting columns are installed in the limiting sliding groove 1a4 in cooperation, so that the baffle 4 can be fixed on the gun 1a, and the baffle 4 is very convenient to disassemble and assemble. In addition, in order to prevent the baffle 4 from automatically sliding out of the limiting sliding groove 1a4 during use, a rotatable limiting stop piece 5 can be additionally arranged on one side of the gun 1a (such as the side close to the open end of the limiting sliding groove 1a4). When the baffle 4 is installed in place, the limiting stop piece 5 only needs to be rotated to the position abutting against the baffle 4, so that the baffle 4 can be limited, and the stability of the baffle 4 during the gunning operation can be ensured, thereby avoiding the influence of the displacement of the baffle 4 on the gunning effect.
