Abstract
Description
Technical Field
[0001] This application belongs to the technical field of mortar spraying equipment, specifically relating to mortar spraying machines. Background Technology
[0002] The cement mortar used for spraying is mainly composed of cement, lime, sand, and water. Its fluidity is poor, requiring a specialized mortar mixer for mixing before spraying. Some existing mortar mixers lack dedicated air pumps and require external air stations for supply, resulting in high operating costs and inconvenience for on-site operations. Other mortar mixers are equipped with spraying air pumps, but due to the high viscosity of cement mortar, the spraying pressure is generally insufficient, leading to poor spraying results and low efficiency. Utility Model Content
[0003] In view of at least one of the above-mentioned defects or deficiencies in the prior art, this application provides a mortar spraying machine that can effectively increase the mortar spraying pressure and spraying volume, thereby achieving efficient mortar spraying.
[0004] To achieve the above objectives, this application provides a mortar mixer, comprising:
[0005] frame;
[0006] A material bin is installed in the frame and has a material outlet.
[0007] A mortar booster pump is installed in the frame and includes a booster pump inlet connected to the discharge port of the housing and a booster pump outlet for connecting to the mortar spray gun assembly.
[0008] Two air compressors are housed in the frame; and
[0009] The three-way connector includes two connector air inlets and one connector air outlet. The two connector air inlets are respectively connected to the air outlets of the two air compressors. The connector air outlet is used to connect to the mortar spray gun assembly.
[0010] In some embodiments, the air compressor includes a high-power motor.
[0011] In some embodiments, the air compressor further includes a compressor body and an air tank forming a pipeline connection, and the high-power motor is driven and connected to the compressor body.
[0012] In some embodiments, the connector inlet is detachably connected to the compressor outlet.
[0013] In some embodiments, the mortar machine also includes a feed tube connector for forming a quick-release connection with the mortar spray gun assembly.
[0014] In some embodiments, the mortar booster pump is a screw pump.
[0015] In some embodiments, the frame includes a frame body, a caster assembly, and a handrail, the caster assembly being disposed at the bottom of the frame body and the handrail being disposed at the top of the handrail frame body.
[0016] In some embodiments, the mortar machine further includes a stirring shaft disposed in the hopper and a stirring motor connected to the stirring shaft, wherein the peripheral wall of the stirring shaft is provided with stirring blades.
[0017] In some embodiments, the mortar machine further includes an electrical controller disposed in the frame, the electrical controller being electrically connected to the mortar booster pump, the two air compressors and the mixing motor respectively.
[0018] In some embodiments, the power controller further includes a control panel having a start switch for sending a start signal.
[0019] Through the above technical solution, the mortar machine of this application can use two air compressors to simultaneously generate high-pressure air. The superposition of the two high-pressure air streams significantly increases the spraying air pressure of the mortar, making it suitable for cement mortar with high viscosity. This results in higher uniformity of the sprayed cement mortar, thereby improving the spraying effect. Simultaneously, the use of a mortar booster pump to pressurize the mortar in the hopper increases its flowability, further enhancing its uniformity, and also increases the output volume of the mortar, thereby improving the mortar spraying efficiency.

[0032] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0033] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.
[0034] like Figure 1 and Figure 2 As shown in the exemplary embodiment of this application, a mortar machine is provided. The mortar machine includes a frame 1, a material box 2, a mortar booster pump 3, two air compressors 4, and a three-way connector 5. The material box 2 is disposed in the frame 1 and has a box outlet. The mortar booster pump 3 is disposed in the frame 1 and includes a booster pump inlet and a booster pump outlet. The booster pump inlet is connected to the box outlet to allow the mortar booster pump 3 to draw in mortar material. The booster pump outlet is used to connect to a mortar spray gun assembly so that the drawn-in mortar material is sprayed out from the mortar spray gun assembly under high pressure. The two air compressors 4 are disposed in the frame 1. The three-way connector 5 includes two connector air inlets and one connector air outlet. The two connector air inlets are respectively connected to the compressor air outlets of the two air compressors 4. The connector air outlet is used to connect to the mortar spray gun assembly so that the high-pressure air generated by the two air compressors 4 is input into the mortar spray gun assembly, mixed with the mortar material, and then sprayed out under high pressure.
[0035] Therefore, the mortar machine of this exemplary embodiment can utilize two air compressors 4 to simultaneously generate high-pressure air. The superposition of the two high-pressure air streams significantly increases the spraying air pressure of the mortar, making it suitable for cement mortars with high viscosity. This results in a higher uniformity of the sprayed cement mortar, thereby improving the spraying effect. Simultaneously, the mortar booster pump 3 pressurizes the mortar in the hopper, increasing the fluidity of the mortar inside the hopper and further enhancing its uniformity. It also increases the output volume of the mortar, thereby improving the mortar spraying efficiency.
[0036] In an optional or preferred embodiment, the air compressor 4 includes a high-power motor with a power of at least 2.75 kW. When two air compressors 4 operate simultaneously, the total power of the motor reaches at least 5.5 kW, further ensuring that the mortar machine can spray mortar coating at high pressure.
[0037] In an optional or preferred embodiment, such as Figure 1 As shown, the air compressor 4 also includes a compressor body 401 and an air tank 402 connected by a pipeline. The air tank 402 can pre-store compressed air, and a high-power motor drives the compressor body 401. Thus, when the high-power motor drives the compressor body 401, the air tank 402 can stably supply air to the compressor body 401 to avoid interruption of air supply and ensure better continuity and uniformity of mortar spraying.
[0038] In an optional or preferred embodiment, the air inlet of the connector and the air outlet of the compressor form a detachable connection, thereby allowing for easy disassembly of the air compressor 4. This is especially useful when processing mortar with low viscosity, where only one air compressor 4 is needed to provide sufficient spraying pressure. In this case, the other air compressor 4 can be removed, reducing the overall weight of the mortar mixer and making it easier to carry to the construction site. In this embodiment, the air inlet of the connector and the air outlet of the compressor can be connected by a threaded structure, a plug-in structure, a snap-fit structure, or a clamp, etc. Any structural component that enables a detachable connection falls within the protection scope of this application. The above structural components are well known to those skilled in the art and are not part of the core improvement of this application, and therefore will not be described in detail here.
[0039] In an optional or preferred embodiment, the mortar machine further includes a material pipe connector 6 that can form a quick-release connection with the mortar delivery pipe of the mortar spray gun assembly. The material pipe connector 6 may be provided with a threaded structure, snap-fit structure, plug-in structure or flange structure that mates with the mortar delivery pipe. This application does not limit this, as long as it can realize the quick plug-in of the mortar delivery pipe. This can improve the versatility of the mortar machine and facilitate the replacement of suitable spray gun assemblies to achieve the ideal spraying effect.
[0040] In an optional or preferred embodiment, the mortar booster pump 3 is a screw pump with an internal feeding screw. This screw pump has the characteristics of large feeding capacity and low cost, and is suitable for the large-scale production of the mortar machine of this application. Its specific structure is well known to those skilled in the art and is not part of the core improvement of this application, so it will not be described in detail here.
[0041] In an optional or preferred embodiment, such as Figure 1As shown, the frame 1 includes a frame body 101, a caster assembly 102, and a handrail 103. The caster assembly 102 is located at the bottom of the frame body 101, and the handrail 103 is located at the top of the frame body 101. Therefore, construction workers can move the mortar machine of this embodiment to the target construction location by pushing or pulling the handrail 103, facilitating site relocation and saving time and effort.
[0042] In an optional or preferred embodiment, such as Figure 1 As shown, the mortar machine of this application also includes a mixing shaft disposed in the material box 2 and a mixing motor 7 that drives the mixing shaft. The peripheral wall of the mixing shaft is provided with mixing blades. The mixing motor 7 drives the mixing shaft to rotate, thereby enabling the mixing blades to fully mix the mortar material in the material box 2 and further improve its uniformity.
[0043] In an optional or preferred embodiment, such as Figure 2 As shown, the mortar machine also includes an electrical controller 8 installed in the frame 1. The electrical controller 8 is electrically connected to the mortar booster pump 3, the two air compressors 4, and the mixing motor 7. Furthermore, the electrical controller 8 also includes a control panel with a start switch for sending a start signal. After the main power is connected via the electrical controller 8, the construction personnel can start the mortar machine of this embodiment with a single button press using the start switch, controlling the mortar booster pump 3, the two air compressors 4, and the mixing motor 7 to operate simultaneously. The entire process is simple to operate, and automated mixing and spraying operations can be achieved without manual control after startup, which helps improve the efficiency of spraying operations.
[0044] Overall, the mortar spraying machine of this application is primarily designed for the spraying needs of mortars with high viscosity. It employs multiple air compressors and a mortar booster pump working in tandem to improve the spraying effect. The multiple air compressors can be disassembled and reassembled as needed, offering high flexibility. The mortar spraying machine and spray gun assembly can also be quickly disassembled and reassembled, facilitating equipment upgrades. Furthermore, it supports disassembly and cleaning, reducing the difficulty of cleaning the equipment. The entire mortar spraying machine has a simplified structure, moderate size, and is easy to carry, making it particularly suitable for smaller construction sites and facilitating large-scale production and widespread use.
