[0033] like Figure 1-Figure 7 As shown, the present invention provides a construction mortar spraying device for construction engineering, including a suction pump and a control cabinet, the suction pump is used to suck mortar, the above content is the prior art, and the specific structure is not repeated here. The device also includes a bottom plate 10, a top plate 11, a lifting assembly 20, a curved guide rail, a first drive assembly 40, a spray box 50 and a second drive assembly 60.

[0034] The top plate 11 is disposed above the bottom plate 10 in the lateral direction.

[0035] There are two lifting assemblies 20, and the two lifting assemblies 20 are arranged opposite to each other. The lifting assemblies 20 include a slider 21, a connecting plate 22, and a straight guide rail 23. The connecting plate 22 is fixedly mounted on the slider 21. The straight guide rail 23 is arranged in the transverse direction, and the first end of the straight guide rail 23 is fixedly connected to the connecting plate 22.

[0036] The two ends of the curved guide rail are detachably connected to the second ends of the two straight guide rails 23 respectively, and the curved guide rail is adapted to the arc-shaped protrusion and / or right-angle protrusion of the wall.

[0037] The first driving assembly 40 is used to control the two lifting assemblies 20 to move up and down synchronously. The first driving assembly 40 includes a first guide rod 41, a first lead screw 42 and a first motor 43. The first guide rod 41 is arranged in the longitudinal direction, and its two ends are respectively fixedly connected to the bottom plate 10 and the top plate 11, and the first guide rod 41 is slidably connected to one of the sliders 21. The first lead screw 42 is arranged in the longitudinal direction, and its two ends are respectively rotatably connected to the bottom plate 10 and the top plate 11, and the first lead screw 42 is threadedly connected to the other slider 21. The first motor 43 is fixedly mounted on the top plate 11 and is electrically connected to the control cabinet. The first motor 43 is used to control the rotation of the first lead screw 42.

[0038] There are multiple spray boxes 50, which are arranged at intervals in the transverse direction, and two adjacent spray boxes 50 are hinged. The spray box 50 can move freely on the straight guide rail 23 and / or the curved guide rail. The spray box 50 is connected to the outlet of the suction pump through a hose 52, and a plurality of spray ports 51 are opened on the side of the spray box 50.

[0039] The second driving assembly 60 is used to control the spray box 50 to move on the straight guide rail 23 and / or the curved guide rail.

[0040] The working process of this equipment is:

[0041] In the first step, the staff places the device on the ground and in front of the wall. At this time, the straight guide rail 23 corresponds to the plane of the wall, and the curved guide rail corresponds to the arc-shaped protrusion and / or right-angle protrusion of the wall.

[0042] In the second step, the staff controls the suction pump to start through the control cabinet, and the suction pump sucks the mortar, and the mortar passes through the hose 52 and the spray box 50, and then sprays out from the spray port 51 and sprays on the wall. At the same time, the control cabinet controls the first motor 43 to start, and the first motor 43 drives the first lead screw 42 to rotate. Under the action of the first guide rod 41, the curved guide rail, the spray box 50 and the two lifting assemblies 20 will move up and down synchronously, so as to spray the wall.

[0043] In the third step, the second driving assembly 60 is started, and the spray box 50 moves a certain distance laterally on the straight guide rail 23 and / or the curved guide rail, and the second step is repeated to continue spraying the unsprayed part of the wall.

[0044] It is worth noting that under the action of the second drive assembly 60, when the multiple spray boxes 50 move to the plane of the wall, the multiple spray boxes 50 are all located on the straight guide rail 23, presenting a straight line. Therefore, under the action of the first drive assembly 40 and the suction pump, the multiple spray boxes 50 can move up and down, thereby performing spraying operations on the plane of the wall.

[0045] Under the action of the second driving assembly 60, when multiple spray boxes 50 move to the arc-shaped protrusions and / or right-angled protrusions of the wall, the multiple spray boxes 50 are all located on the curved guide rail, presenting a shape that is adapted to the arc-shaped protrusions and / or right-angled protrusions of the wall. Therefore, under the action of the first driving assembly 40 and the suction pump, the multiple spray boxes 50 can move up and down, thereby performing spraying operations on the arc-shaped protrusions and / or right-angled protrusions of the wall.

[0046] In one embodiment, a straight guide groove 24 is formed on the straight guide rail 23 , and a curved guide groove is formed on the curved guide rail. The notch of the curved guide groove is aligned with the notch of the straight guide groove 24 .

[0047] A guide wheel is provided at the bottom of the spray box 50, and the guide wheel is connected to the spray box 50. The guide wheel is adapted to both the straight guide groove 24 and the curved guide groove.

[0048] Under the action of the second driving assembly 60, when the spray box 50 moves on the straight guide rail 23 and / or the curved guide rail, the guide wheel at the bottom thereof moves in the straight guide groove 24 and / or the curved guide groove to play a guiding role. Since the notch of the curved guide groove is aligned with the notch of the straight guide groove 24, the spray box 50 can smoothly move from the straight guide rail 23 to the curved guide rail, or from the curved guide rail to the straight guide rail 23.

[0049] In one embodiment, the second driving assembly 60 includes a second guide rod 61, a second lead screw 62, a second motor 63 and a guide plate 64. The second guide rod 61 is arranged in a transverse direction, and its two ends are respectively fixedly connected to the two connecting plates 22. The second lead screw 62 is arranged in a transverse direction, and its two ends are respectively rotatably connected to the two connecting plates 22. The second motor 63 is fixedly mounted on one of the connecting plates 22 and is electrically connected to the control cabinet, and the second motor 63 is used to control the rotation of the second lead screw 62. The guide plate 64 is slidably connected to the second guide rod 61 and is also threadedly connected to the second lead screw 62. A plurality of waist-shaped grooves 65 are formed on the guide plate 64, and the plurality of waist-shaped grooves 65 correspond to a plurality of spray boxes 50 one by one. A guide column 66 is arranged in the waist-shaped groove 65, and the guide column 66 is adapted to the inner wall of the waist-shaped groove 65 and is also connected to the corresponding spray box 50.

[0050] When the second driving assembly 60 is working, the control cabinet controls the second motor 63 to start, and the second motor 63 drives the second lead screw 62 to rotate. Under the action of the second guide rod 61, the guide plate 64 will move laterally, and the guide column 66 will drive the corresponding spray box 50 to move laterally synchronously, thereby driving the spray box 50 to move on the straight guide rail 23 and / or the curved guide rail.

[0051] It should be noted that due to the existence of the kidney-shaped groove 65, when the spraying box 50 enters the curved guide rail from the straight guide rail 23, or enters the straight guide rail 23 from the curved guide rail, the guiding column 66 will move within the kidney-shaped groove 65, so that there will be no jamming phenomenon between the guiding plate 64 and the spraying box 50.

[0052] In one embodiment, the curved guide rail includes a semi-circular guide rail 31 and a U-shaped guide rail 32. The semi-circular guide rail 31 and the U-shaped guide rail 32 respectively adapt to the arc-shaped protrusion and / or right-angle protrusion of the wall, which are the two most common situations. If the wall has other shaped protrusions, the staff can customize the shape of the curved guide rail.

[0053] In one embodiment, the guiding column 66 is in rolling contact with the inner wall of the kidney-shaped groove 65 and is also rotatably connected to the corresponding spraying box 50. When the guiding column 66 moves within the kidney-shaped groove 65, the guiding column 66 will be in rolling contact with the inner wall of the kidney-shaped groove 65, thereby reducing the friction between the two and making the operation of the device smoother.

[0054] In one embodiment, a screw 25 is provided on the straight guide rail 23. The threaded end of the screw 25 passes through the straight guide rail 23 and is threadedly connected to the curved guide rail. The detachable connection between the straight guide rail 23 and the curved guide rail is realized through the screw 25, and the structure is simple and convenient to use.

[0055] In one embodiment, the guiding wheel is rotatably connected to the spraying box 50, and the guiding wheel is in rolling contact with the inner walls of both the straight guiding groove 24 and the curved guiding groove.

[0056] When the guiding wheel moves within the straight guiding groove 24 and / or the curved guiding groove, the guiding column 66 will be in rolling contact with the inner wall of the straight guiding groove 24 or the inner wall of the curved guiding groove, thereby reducing the friction between the two and making the operation of the device smoother.

[0057] In one embodiment, the guiding plate 64 is arranged above the spraying box 50 to reduce the risk of mortar falling on the guiding plate 64.
