Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, and specifically relates to a building mortar spraying device for building engineering. Background Technology

[0002] Currently, mortar spraying machines are specialized equipment that mechanically pressurize, transport, and atomize cement mortar, putty, and other paste-like building materials and spray them onto construction surfaces such as walls and floors. They can replace traditional manual plastering and significantly improve construction efficiency.

[0003] However, existing mortar spraying machines generally consist of three parts: a movable main body, a mortar delivery pipe, and a spray head. When using them, workers need to hold the spray head towards the wall and control its swing to ensure that the mortar can adhere evenly to the wall. However, manual back-and-forth swinging cannot guarantee a stable swing amplitude, which may result in some areas being sprayed repeatedly, leading to inconsistent spray thickness and waste. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a building mortar spraying device for construction projects.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a building mortar spraying device for construction engineering, including a walking frame, a feeding device installed on the top of the walking frame, and the feeding device being detachably connected to and connected to a spraying device.

[0006] Preferably, the feeding device includes a screw feeder and a feeding hopper. The screw feeder is installed above the traveling frame, and the feeding hopper is installed on the outer periphery of the screw feeder and communicates with the screw feeder. The feeding device is detachably connected to and communicates with the output end of the screw feeder.

[0007] Preferably, the feeding device further includes a rectangular frame, which is mounted above the feed hopper by multiple springs. A screen is installed inside the rectangular frame, and vibrators are installed around the perimeter of the rectangular frame.

[0008] Preferably, the spraying device includes a material conveying pipe and a nozzle mechanism. The material conveying pipe is detachably connected to and communicates with the output end of the screw feeder. The nozzle mechanism is installed and communicates with the end of the material conveying pipe. A high-pressure conveying mechanism is installed above the traveling frame. The high-pressure conveying mechanism is detachably connected to and communicates with the nozzle mechanism.

[0009] Preferably, the nozzle mechanism includes a connecting pipe and a connecting hose. The connecting pipe is installed and connected to the end of the conveying pipe away from the screw feeder. The connecting hose is installed and connected to the end of the connecting pipe. The end of the connecting hose away from the connecting pipe is detachably connected and connected to a nozzle. The connecting pipe is detachably connected and connected to a high-pressure conveying mechanism. A swing mechanism is installed between the connecting pipe and the nozzle.

[0010] Preferably, the swing mechanism includes a mounting sleeve and a bidirectional motor. The mounting sleeve is installed on the outer periphery of the connecting pipe, and the bidirectional motor is installed inside the mounting sleeve. Both output ends of the bidirectional motor are hinged to eccentric connecting rods, and the other end of the eccentric connecting rod is hinged to a driving connecting rod. The end of the driving connecting rod away from the eccentric connecting rod is hinged to the spray head through the swing assembly.

[0011] Preferably, the oscillating assembly includes an extension bar installed on the outer periphery of the connecting pipe, and a rotating connecting rod hinged above the extension bar. The rotating connecting rod is hinged to the driving connecting rod and to the outer periphery of the nozzle.

[0012] Preferably, the high-pressure conveying mechanism includes an air compressor and a high-pressure air pipe, with the air compressor installed above the vehicle frame and the high-pressure air pipe installed and connected between the air compressor and the connecting pipe.

[0013] Preferably, a front grip and a rear grip are installed on the outer periphery of the connecting tube, and the outer surfaces of the front grip and the rear grip are covered with anti-slip sleeves.

[0014] Preferably, the walking frame includes a frame and a push handle. The push handle is installed on the side of the frame in the direction of travel. Front wheel axles are rotatably connected to both sides of the frame away from the push handle. Front wheels are installed at the ends of the front wheel axles away from the frame. Two omnidirectional casters are installed under the frame. The outer surface of the push handle is covered with an anti-slip rubber sleeve.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows: (1) Existing mortar spraying machines spray by manually adjusting the nozzles, while the present invention installs a feeding device on the top of the walking frame. The feeding device is detachably connected to and connected to the spraying device, integrating feeding and spraying functions, thereby reducing the difficulty of manual operation and greatly improving the work efficiency of building mortar spraying. (2) A rectangular frame is connected above the feed hopper by a spring, and a screen is installed inside the rectangular frame. Vibrators are installed around the rectangular frame, so that the mortar can be continuously vibrated and screened to effectively remove large particles of impurities, avoid clogging and wear of the screw feeder, and extend the service life of the equipment. (3) The swing mechanism composed of bidirectional motor, eccentric connecting rod, driving connecting rod and rotating connecting rod can drive the spray head to swing horizontally and achieve uniform spraying of mortar, avoid the problems of missed spraying and repeated spraying that occur in manual spraying, and improve the uniformity of wall mortar adhesion and construction flatness. (4) The swing mechanism enables workers to achieve large-area spraying by simply moving the spray head vertically, and the swing amplitude of the spray head remains consistent, so there will be no problem of re-spraying some areas multiple times. (5) Through the high-pressure conveying mechanism composed of air compressor and high-pressure air pipe, the high-pressure airflow can help the mortar to be sprayed smoothly, enhance the adhesion between the mortar and the wall, reduce the mortar falling and wasting, and improve the spraying quality and construction effect. (6) The outer periphery of the connecting pipe is equipped with mutually perpendicular front and rear handles. When holding it with both hands, the angle of the spray head can be flexibly controlled, and a stable rear support can be obtained to balance the weight of the equipment. It conforms to the ergonomic grip posture, effectively reducing the labor intensity of construction personnel and making the operation more precise and labor-saving. Attached Figure Description

Figure 1 As shown, the device includes a walking frame 1, characterized in that a feeding device is installed on the top of the walking frame 1, and the feeding device is detachably connected to and connected to a spraying device.

[0021] like Figure 1 As shown, the feeding device includes a screw feeder 4 and a feeding hopper 7.

[0022] like Figure 1 As shown, the feeding device also includes a rectangular frame 9, which is mounted above the feed hopper 7 by multiple springs 8. A screen 10 is installed inside the rectangular frame 9, and vibrators are installed around the rectangular frame 9.

[0023] like Figures 1-4 As shown, the spraying device includes a conveying pipe 5 and a nozzle mechanism 6. The conveying pipe 5 is detachably connected to and communicates with the output end of the screw feeder 4. The nozzle mechanism 6 is installed and communicates with the end of the conveying pipe 5. A high-pressure conveying mechanism is installed above the traveling frame 1. The high-pressure conveying mechanism is detachably connected to and communicates with the nozzle mechanism 6.

[0024] like Figures 1-4 As shown, the nozzle mechanism 6 includes a connecting pipe 61 and a connecting hose 62. The connecting pipe 61 is installed and connected to the end of the conveying pipe 5 away from the screw feeder 4. The connecting hose 62 is installed and connected to the end of the connecting pipe 61. The end of the connecting hose 62 away from the connecting pipe 61 is detachably connected and connected to a nozzle 63.

[0025] like Figures 1-4As shown, the swing mechanism includes a mounting sleeve 610 and a bidirectional motor. The mounting sleeve 610 is installed on the outer periphery of the connecting pipe 61, and the bidirectional motor is installed inside the mounting sleeve 610. Both output ends of the bidirectional motor are hinged to eccentric connecting rods 611. The other end of the eccentric connecting rod 611 is hinged to a driving connecting rod 612. The end of the driving connecting rod 612 away from the eccentric connecting rod 611 is hinged to the nozzle 63 through the swing assembly.

[0026] like Figures 1-4 As shown, the oscillating assembly includes an extension bar 64, which is installed on the outer periphery of the connecting pipe 61. A rotating connecting rod 65 is hinged above the extension bar 64. The rotating connecting rod 65 is hinged to the driving connecting rod 612 and is also hinged to the outer periphery of the nozzle 63.

[0027] like Figure 1 and Figure 2 As shown, the high-pressure conveying mechanism includes an air compressor 11 and a high-pressure air pipe 66. The air compressor 11 is installed above the traveling frame 1, and the high-pressure air pipe 66 is installed and connected between the air compressor 11 and the connecting pipe 61.

[0028] like Figure 2 As shown, a front grip 67 and a rear grip 68 are installed on the outer periphery of the connecting pipe 61, and anti-slip sleeves are fitted on the outer surfaces of both the front grip 67 and the rear grip 68.

[0029] like Figure 1 As shown, the walking frame 1 includes a frame and a push handle 14. The push handle 14 is installed on the side of the frame in the direction of travel. Front wheel axles are rotatably connected to both sides of the frame away from the push handle 14. Front wheels 12 are installed at the ends of the front wheel axles away from the frame. Two universal casters 13 are installed under the frame. The outer surface of the push handle 14 is covered with an anti-slip rubber sleeve.

[0030] In this invention, an equipment box 2 is installed on the top of the vehicle frame, and a screw feeder 4 is fixedly connected to the top of the vehicle frame via a bracket 3, with the drive end of the screw feeder 4 located inside the equipment box 2.

[0031] In this invention, multiple heat dissipation slots 15 are provided on both sides of the equipment box 2.

[0032] In this invention, the screw feeder 4 is a conventional screw feeder.

[0033] In this invention, the nozzle 63 can be selected with different nozzle shapes according to the construction site conditions.

[0034] In this invention, the hinge point between the eccentric connecting rod 611 and the output end of the bidirectional motor is eccentrically set with respect to the center of the output end of the bidirectional motor.

[0035] In this invention, the front grip 67 is located between the mounting sleeve 610 and the rear grip 68, and the high-pressure air pipe 66 is located near the connection between the connecting pipe 61 and the connecting hose 62 at the position where it communicates with the connecting pipe 61.

[0036] In this invention, the equipment box 2 is equipped with a power supply, which provides kinetic energy to the bidirectional motor, air compressor 11, screw feeder 4 and vibrator.

[0037] In this invention, there are four springs 8, which are located at the four corners of the upper surface of the feed hopper 7, and the springs 8 are existing cylindrical helical compression springs.

[0038] In this invention, the line connecting the two extension strips 64 on the outer periphery of the connecting tube 61 is perpendicular to the axis of the connecting tube 61.

[0039] In this invention, the bidirectional motor is installed in the middle position of the mounting sleeve 610, and the distance between the two output ends of the bidirectional motor is greater than the length of the mounting sleeve 610.

[0040] In the invention, the mounting sleeve 610 is mounted on the outer periphery of the connecting pipe 61 via the connecting seat 69.

[0041] In this invention, the front grip 67 and the rear grip 68 are perpendicular to each other in the length direction. The operator can hold the two grips with both hands to control the movement of the nozzle 63. The front grip 67 facilitates flexible control of the angle of the nozzle 63 by the hand, and the rear grip 68 provides stable rear support to balance the weight of the equipment. The two work together to form an ergonomic grip posture.

[0042] In this invention, the rectangular frame 9 is driven to vibrate by the continuous vibration of the vibrator. Before the cement mortar material is filled into the feed hopper 7, it will pass through the screen 10. The screen 10 can remove larger particles in the mortar, so as to avoid the screw feeder 4 being blocked or damaged. The continuous vibration can improve the screening efficiency of the screen 10.

[0043] In this invention, the height of the upper surface of the screen 10 is lower than the height of the upper surface of the rectangular frame 9.

[0044] In this invention, the bidirectional motor is externally connected to a controller, and the air compressor 11, the screw feeder 4 and the vibrator are all connected to the controller for communication.

[0045] The working principle of this invention is as follows: Construction workers move the entire equipment to the construction site by pushing the handle 14, turn on the vibrator, and allow the cement mortar material to pass through the screen 10 into the screw feeder 4. The screw feeder 4 then feeds the cement mortar material into the conveying pipe 5, and continues to transport it through the conveying pipe 5 until it reaches the connecting pipe 61. After the cement mortar material enters the connecting pipe 61, the air compressor 11 is turned on, and the high-pressure air discharged from the air compressor 11 is sprayed into the connecting pipe 61 through the high-pressure air pipe 66. The cement mortar material is then finally sprayed out through the front end of the spray head 63, thus evenly spraying and adhering to the wall surface. Because the spray head 63 is connected to the connecting pipe 61 through the connecting hose 62, the spray head 63 can move freely without being restricted by the connecting pipe 61. The two are further restricted by a limiting frame structure composed of the top and bottom extension strips 64 and the rotating connecting rod 65, so that the spray head 63 can only swing horizontally. During the spraying process, the spray head 63 in the spray head mechanism 6 will swing horizontally back and forth under the action of the swinging mechanism. That is, the bidirectional motor is turned on, and the output shaft of the bidirectional motor rotates, driving the eccentric connecting rod 611 at the outer end of its two output shafts to rotate. Since the driving connecting rod 612 is hinged to the outer end of the eccentric connecting rod 611, the eccentric connecting rod 611 drives one end of the driving connecting rod 612 to perform a circular motion. The other end of the driving connecting rod 612 is hinged to the outer surface of the rotating connecting rod 65, so the driving connecting rod 612 drives the rotating connecting rod 65 to swing horizontally back and forth, thereby driving the spray head 63 to swing horizontally synchronously.

[0046] In this invention, the above process can be automatically controlled by a controller.

[0047] In this invention, the above process can be adjusted according to the on-site conditions.

[0048] As a technical solution of this invention, the provided hardware configuration is merely for facilitating the implementation of specific braking control based on the hardware facilities. How to specifically implement braking control and the braking control method are not the technical problems to be solved or the objects of protection of this invention. Furthermore, the communication methods between the devices all employ existing communication methods and are not the inventive point of this invention.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
