Description

Technical Field

[0001] The invention relates to the technical field of mortar spraying, in particular to building mortar spraying equipment for construction engineering. Background Art

[0002] Construction mortar spraying equipment is a kind of construction machinery and equipment, which is mainly used to spray mortar or concrete and other materials evenly onto walls, roofs and other construction surfaces. It has a wide range of applications, including internal and external wall spraying, cement mortar spraying, bridge grouting, waterproof surface spraying, fireproof spraying, thermal insulation material spraying, ceiling spraying, paint spraying and garden spraying.

[0003] When a traditional small-scale mortar spraying device is used, the mortar in the mortar barrel will often show obvious sedimentation after being stored for a long time. This is because the solid particles in the mortar gradually sink due to gravity, while water and light components float up, causing the composition of the mortar to become uneven. This unevenness is particularly prominent during the spraying process, because the deposited mortar particles are large and have poor fluidity, while the mortar on the surface is relatively thin and has good fluidity. Therefore, when the spraying device starts working, the mortar sprayed out in the initial stage may be relatively thin, and then the mortar concentration may increase sharply due to blockage or spraying of sediments, resulting in uneven spraying effect and affecting construction quality and efficiency. In addition, the sedimentation phenomenon may also increase the burden on the mixing mechanism and shorten the service life of the equipment. For this reason, we propose a construction mortar spraying equipment for construction projects. Summary of the invention

This unevenness is particularly prominent during the spraying process, because the deposited mortar particles are large and have poor fluidity, while the mortar on the surface is relatively thin and has good fluidity. Therefore, when the spraying device starts working, the mortar sprayed out in the initial stage may be relatively thin, and then the mortar concentration may increase sharply due to blockage or spraying of sediments, resulting in uneven spraying effect, affecting construction quality and efficiency.

[0036] Furthermore, the user moves the device to the position where the mortar needs to be sprayed through the gripping mechanism 3. Subsequently, the air intake mechanism 2 is turned on by the user's operation, and starts to work and control the start and stop of the driving mechanism 4. When the air intake mechanism 2 is started, it provides the required power to the driving mechanism 4 to start running. After the driving mechanism 4 is running, the kinetic energy generated by it is transmitted contactlessly through the magnetic coupling mechanism 5, which can avoid mechanical wear and noise, and at the same time ensure the efficient transmission of kinetic energy. The magnetic coupling mechanism 5 transmits the kinetic energy to the first transmission mechanism 6, and the first transmission mechanism 6 transmits the kinetic energy to the second transmission mechanism 7, and the second transmission mechanism 7 After receiving the kinetic energy, the stirring mechanism 8 starts to operate. The stirring mechanism 8 is located below the mortar barrel 12, and its specially designed stirring blades 803 start to rotate to fully stir the mortar in the mortar barrel 12 to ensure the uniformity and high quality of the mortar. During the stirring process, the user can control the start and stop of the driving mechanism 4 at any time through the air intake mechanism 2, so as to adjust the stirring time and the speed of mortar spraying. This kind of construction mortar spraying equipment for construction projects realizes efficient and uniform stirring and spraying of mortar through the precise coordination between various mechanisms and the working principle of efficient kinetic energy transmission, thereby improving the construction efficiency and quality of construction projects.

[0037] In the preferred technical solution of this embodiment, please refer to Figure 5-Figure 6As shown, the support mechanism 1 includes a substrate 101, a first set of holes 102 is penetrated at one side of the center of the substrate 101, a second set of holes 103 is penetrated at the other side of the center of the substrate 101, a first bearing 104 is fixedly sleeved at the upper and lower ends of the center of the second set of holes 103, a second bearing 105 is fixedly embedded at both sides of one end of the upper end of the substrate 101 near the second set of holes 103, a third bearing 106 is fixedly sleeved at both ends of the center of one side of the upper end of the substrate 101 near the stirring mechanism 8, an air intake check valve 107 is fixedly sleeved at the center of one side of the upper end of the substrate 101 near the two third bearings 106, the input end of the air intake check valve 107 penetrates the upper end of the substrate 101 to the lower end of the substrate 101, and the center of the substrate 101 near the two third bearings 106 is fixedly sleeved There is a guide sleeve 108, and a threaded sleeve 109 is fixedly connected to the lower end of the base plate 101 near the guide sleeve 108. The mortar barrel 12 is threadedly sleeved inside the threaded sleeve 109, and the mortar barrel 12 and the threaded sleeve 109 are detachably connected. A pumping pipe 11 is threadedly sleeved inside the guide sleeve 108, and the pumping pipe 11 and the guide sleeve 108 are detachably connected. The input end of the pumping pipe 11 is connected to the lower part of the mortar barrel 12, and a three-way pipe 9 is threadedly sleeved at one end of the outer side of the pumping pipe 11 near the output end, and the pumping pipe 11 and the three-way pipe 9 are detachably connected. A discharge pipe 10 is threadedly sleeved at one end of the three-way pipe 9, and the discharge pipe 10 and the three-way pipe 9 are detachably connected. A docking air pipe 13 is fixedly sleeved at the center of the interior of the base plate 101 near one side of the air intake mechanism 2.

[0038] Furthermore, the support mechanism 1 not only bears the weight of the entire device, but also provides a stable installation foundation and rotation support for other components through the sleeve holes and bearings designed inside. The first sleeve holes 102 and the second sleeve holes 103 respectively accommodate the key components of the driving mechanism 4 and the first transmission mechanism 6, ensuring the stability and efficiency of the driving mechanism 4 and the first transmission mechanism 6 during operation, while the second bearing 105 and the third bearing 106 respectively support the second transmission mechanism 7 and the stirring mechanism 8, so that the stirring action can be carried out smoothly, and the air intake is one-way. The valve 107 allows gas to enter the mortar barrel 12 in one direction, thereby achieving a constant pressure effect. The guide sleeve 108 and the threaded sleeve 109 cleverly realize the detachable connection of the mortar barrel 12, which is convenient for loading and unloading of the mortar, and also convenient for cleaning and replacement of the mortar barrel 12. The detachable connection between the extraction pipe 11 and the guide sleeve 108, as well as the design of the three-way pipe 9 and the discharge pipe 10, together constitute the mortar conveying path, ensuring that the mortar can be smoothly extracted from the mortar barrel 12 and sprayed out through the discharge pipe 10.

[0039] In the preferred technical solution of this embodiment, please refer to Figure 7-Figure 8As shown, the air intake mechanism 2 includes a rear handle 201, which is fixedly connected to one side of the center of the lower end of the substrate 101, a manual air valve 202 is fixedly connected to one side of the rear handle 201, and a docking pipe 203 is fixedly connected to the lower end of the rear handle 201. The output end of the docking pipe 203 passes through the lower end of the rear handle 201 and passes into the interior of the rear handle 201, and the output end of the docking pipe 203 is fixedly connected to the input end of the manual air valve 202, and the input end of the docking air pipe 13 is fixedly connected to the output end of the manual air valve 202. The grasping mechanism 3 includes two connecting blocks 301, and the two connecting blocks 301 are fixedly connected to both sides of the center of the lower end of the substrate 101 near one end of the threaded sleeve 109, and the lower ends of the two connecting blocks 301 are fixedly connected to a support plate 302, and the lower end of the support plate 302 is fixedly connected to a front handle 303.

[0040] Furthermore, the design of the air intake mechanism 2 fully considers the convenience and safety of user operation. The rear handle 201 not only provides the user with a stable holding point, but also realizes precise control of the air intake volume through the manual air valve 202 and the docking pipe 203. When the user needs to generate power through the driving mechanism 4, he only needs to simply operate the manual air valve 202 to allow the gas to enter the driving mechanism 4 through the docking air pipe 13, thereby triggering the driving mechanism 4 to operate. The grasping mechanism 3 provides the user with another stable holding point through the clever combination of the connecting block 301, the support plate 302 and the front handle 303, allowing the user to operate the equipment more easily.

[0041] In the preferred technical solution of this embodiment, please refer to Figure 9-10 As shown, the driving mechanism 4 includes a bottom ring 401, which is fixedly connected to the upper end of the substrate 101 near the first set of holes 102, and an air collecting chamber 402 is fixedly connected to the center of the upper end of the bottom ring 401 near the edge, and a top cover 403 is fixedly connected to the upper end of the air collecting chamber 402, and a fourth bearing 404 is fixedly embedded in the top cover 403 and the inner center of the bottom ring 401, and a driving rod 405 is fixedly sleeved on the inner ring of the two fourth bearings 404, and a blower impeller 406 is fixedly sleeved on the outer side of the driving rod 405, and an air inlet pipe 407 and an air outlet pipe 408 are respectively fixedly connected to the outer side of the air collecting chamber 402 near both ends, and the output end of the air inlet pipe 407 and the input end of the air outlet pipe 408 both pass through the outside of the air collecting chamber 402 to the inside of the air collecting chamber 402, the input end of the air inlet pipe 407 is fixedly connected to the input end of the docking air pipe 13, and the air outlet pipe 408 is fixedly connected to the other end of the three-way pipe 9.

[0042] Furthermore, the driving mechanism 4 is the power source of the entire equipment. The bottom ring 401 and the top cover 403 together constitute the main structure of the driving mechanism 4, providing a stable rotation environment for the internal blower impeller 406. When the user inputs gas into the air collecting chamber 402 through the air intake mechanism 2, the blower impeller 406 begins to rotate under the push of the gas, and transmits the rotational power to the magnetic coupling mechanism 5 through the driving rod 405. At the same time, the air outlet pipe 408 discharges the gas passing through the air collecting chamber 402, and a Bernoulli effect is generated when passing through the three-way pipe 9 and the extraction pipe 11, so that the mortar in the mortar barrel 12 is extracted through the extraction pipe 11 and sprayed out through the discharge pipe 10. This design not only improves the spraying efficiency of the mortar, but also ensures the uniform spraying of the mortar.

[0043] In the preferred technical solution of this embodiment, please refer to Figure 11-Figure 12 As shown, the magnetic coupling mechanism 5 includes a driving sleeve 501 and an isolation tube 502. The driving sleeve 501 is fixedly connected to the lower end of the driving rod 405, and the isolation tube 502 is fixedly connected to the center of the lower end of the bottom ring 401. A sealing ring 503 is fixedly connected to the lower end of the isolation tube 502. A sealing sleeve 504 is fixedly sleeved inside the sealing ring 503. A support sleeve 505 is fixedly connected to the lower end of the sealing ring 503. A fifth bearing 506 is fixedly sleeved at the center of the support sleeve 505. A transmission rod 507 is fixedly sleeved on the inner ring of the fifth bearing 506. A first transmission column 508 is fixedly connected to the upper end of the transmission rod 507. A plurality of driving permanent magnets 509 are fixedly embedded in a ring-shaped arrangement on the inner wall of the driving sleeve 501, and a plurality of transmission permanent magnets 5010 are fixedly embedded in a ring-shaped arrangement on the outer side of the first transmission column 508.

[0044] Furthermore, the innovative design of the magnetic coupling mechanism 5 realizes contactless power transmission between the driving mechanism 4 and the first transmission mechanism 6. The driving sleeve 501 and the isolation tube 502 together constitute the main structure of the magnetic coupling mechanism 5, and the rotational power generated by the driving mechanism 4 is transmitted to the first transmission mechanism 6 through magnetic action. The ingenious arrangement of the driving permanent magnet 509 and the transmission permanent magnet 5010 enables the two to maintain a stable magnetic coupling effect during relative rotation, thereby realizing loss-free power transmission. This design not only improves the overall efficiency of the equipment, but also effectively extends the service life of the equipment.

The second transmission wheel 704 and the third transmission wheel 705 are fixedly connected to the upper ends of the two positioning columns 701 respectively, the fourth transmission wheel 706 is fixedly connected to the top of the third transmission wheel 705, the fifth transmission wheel 707 is fixedly connected to the top of the second transmission wheel 704, the sixth transmission wheel 708 is fixedly connected to the upper end of the first transmission wheel 702, the first transmission wheel 702 and the second transmission wheel 704 are sleeved with a first transmission belt 709 on the outer side, the fourth transmission wheel 706 and the sixth transmission wheel 708 are sleeved with a second transmission belt 7010, the seventh transmission wheel 7011 and the eighth transmission wheel 7012 are fixedly connected to the upper ends of the two second transmission columns 703 respectively, the third transmission wheel 705 and the seventh transmission wheel 7011 are sleeved with a third transmission belt 7013 on the outer side, the fourth transmission belt 7014 is sleeved on the outer side of the fifth transmission wheel 707 and the eighth transmission wheel 7012, and the upper protective cover 7015 is fixedly connected to one side of the center of the upper end of the substrate 101.

[0046] Furthermore, the first transmission mechanism 6 and the second transmission mechanism 7 together constitute the transmission system of the equipment. The first drive wheel 601 starts to rotate under the drive of the magnetic coupling mechanism 5, and transmits the rotational power to the second drive wheel 603 through the drive belt 604. This design not only realizes the smooth transmission of power, but also effectively reduces the noise and vibration during the transmission process. The second transmission mechanism 7 further transmits the rotational power generated by the first transmission mechanism 6 to the stirring mechanism 8 through a combination of multiple transmission wheels and transmission belts, thereby driving the stirring blades 803 to rotate and stir. This design not only ensures the smooth progress of the stirring action, but also effectively improves the stirring efficiency of the mortar.

[0047] In the preferred technical solution of this embodiment, please refer to Fig.16As shown, the stirring mechanism 8 includes two docking plates 801, and the two docking plates 801 are respectively assembled on the lower ends of the two second transmission columns 703, and the two docking plates 801 are detachably connected to the two second transmission columns 703, and the lower ends of the two docking plates 801 are fixedly connected to connecting rods 802, and the outer sides of the two connecting rods 802 are fixedly connected to multiple stirring blades 803 arranged in a ring.

[0048] Furthermore, the stirring mechanism 8 is the core working component of the equipment. The two docking plates 801 are respectively assembled on the lower ends of the two second transmission columns 703, and are connected to the stirring blades 803 through the connecting rods 802. When the second transmission mechanism 7 transmits the rotational power to the docking plates 801, the stirring blades 803 start to rotate, and the mortar in the mortar barrel 12 is fully stirred. The special design of the stirring blades 803 ensures the uniformity and efficiency of the mortar during the stirring process, thereby improving the quality of the mortar and the spraying effect.
