[0056] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0057] The dry-mix mortar pump according to the present invention will be described below with reference to the accompanying drawings.

[0058] like Figures 1 to 6 As shown, in an embodiment of the present invention, a dry-mix mortar pump 100 includes a hopper 1, a water supply system 2, a power unit 3 and a controller 4. A feeding port 11 and a supply port 12 are respectively provided at the upper and lower ends of the hopper 1, and the size of the feeding port 11 is larger than that of the supply port 12; the power unit 3 includes a stirring assembly, a mortar pump 33 and a stirring drum 34 with a stirring chamber 341. The stirring drum 34 is provided with a water supply port connected to the stirring chamber 341, the water supply system 2 is connected to the water supply port, the lower end of the hopper 1 is connected to the side wall of the stirring drum 34 and the supply port 12 is connected to the stirring chamber 341, the stirring assembly is arranged in the stirring chamber 341, and the discharge port of the stirring drum 34 is located at the lower end of the stirring drum 34 and is connected to the mortar pump 33; the controller 4, the water supply system 2 is connected to the controller 4, and the controller 4 is used to start and stop the water supply system 2.

[0059] It can be understood that the hopper 1 is used to add dry material to the mixing drum 34. The outer wall of the hopper 1 can be installed with a vibration motor 13, which can be used to vibrate and assist in feeding, so as to ensure that the dry material falls smoothly into the mixing drum 34, the feeding is smooth, and it is not easy to be blocked, so that the wet mortar pumped out by the mortar pump 33 is stable and continuous. The vibration motor 13 is a motor vibration type, but is not limited to a motor type vibration motor 13, and should also include other types of vibration motors 13. The mortar pump 33 can be a screw mortar pump, but is not limited to a screw mortar pump, and should also include other types of mortar pumps 33. The water supply port on the mixing drum 34 can be one, but is not limited to one, and can also be two or more.

[0060] The dry-mix mortar pump 100 in this embodiment integrates a hopper 1, a water supply system 2, a power device 3 and a controller 4. Dry material is supplied to the mixing drum 34 through the hopper 1, and the "feeding device" (such as a mobile silo, etc.) in the prior art can be eliminated. The hopper 1 located above the mixing drum 34 can rely on the gravity of the dry mortar to transport the dry material to the mixing drum 34, and the larger-sized feeding port 11 located at the upper part can facilitate the feeding of dry mortar. The water supply system 2 is used to supply water to the mixing drum 34. Combined with the mixing component in the mixing drum 34, the water-adding and mixing of the dry mortar can be achieved. The wet mortar stirred in the mixing drum 34 can flow to the mortar pump 33 located at the bottom of the mixing drum 34 under the action of gravity. The mortar pump 33 can pump the wet mortar. The mortar pump 33 can be connected to the spray gun 63 through the mortar pipe 331. When the spray gun 63 is not used, the dry-mixed mortar pump 100 can be used for the construction of high-flow floor and self-leveling. When used with the spray gun 63, the dry-mixed mortar pump 100 can be used for the spraying of plaster mortar, so that the dry-mixed mortar pump 100 can adapt to a variety of working conditions. In this embodiment, through the integration of the hopper 1, the water supply system 2, the power device 3 and the controller 4, the water mixing of the dry mortar and the pumping of the wet mortar are integrated into one device, which can be applied to a variety of working conditions, is not limited by the application scenario, and greatly improves the convenience of use. In addition, the controller 4 can control the start and stop of the water supply system 2 to ensure the stable and controllable operation of the equipment.

[0061] like Figure 5 As shown, in one embodiment, the water supply system 2 includes a water pump 21, a main water supply path 22 and a cleaning branch 23. The water pump 21 is connected to the water supply port through the main water supply path 22, and a water circuit switch valve 221 is provided on the main water supply path 22; the cleaning branch 23 is connected to the exhaust port of the water pump 21, and the water pump 21 is used to exhaust or clean the hopper 1 through the cleaning branch 23. The water circuit switch valve 221 in this embodiment can be a solenoid valve electrically connected to the controller 4, and the solenoid valve can be controlled by the controller 4 to realize the control of the start and stop of the main water supply path 22, which can facilitate the dry-mixed mortar pump 100. When the dry-mixed mortar pump 100 ends its operation, the water outlet end of the cleaning branch 23 can be extended into the hopper 1, and the dry-mixed mortar pump 100 can be flushed through the cleaning branch 23; before the dry-mixed mortar pump 100 starts to be used, the water pump 21 can be exhausted through the cleaning branch 23 to prevent the gas in the water pump 21 from affecting the water supply of the main water supply path 22.

[0062] In one embodiment, the water supply system 2 further includes a drainage branch 24 with a drainage switch valve 241. A drainage outlet is provided on the water supply main line 22, and the drainage branch 24 is connected to the drainage outlet. The number of drainage branches 24 in this embodiment can be set according to actual use requirements, such as Figure 5As shown, there are two drainage branches 24, and both drainage branches 24 are placed at the low point of the water supply system 2. The drainage switch valve 241 in this embodiment is a ball valve. After the dry-mix mortar pump 100 is used, the drainage switch valve 241 can be opened to drain the residual water in the water supply system 2 through the drainage switch valve 241. The multi-branch design of the water supply system 2 in this embodiment can not only realize the whole machine cleaning and water supply, but also realize the exhaust and drainage of the water supply system 2, without the need for additional drainage or cleaning equipment, which greatly improves the convenience of use.

[0063] Specifically, a water pressure sensor 222 and a pressure reducing valve 223 are provided on the water supply main path 22. The water pressure sensor 222 is located between the water pump 21 and the pressure reducing valve 223. The water pressure sensor 222 and the water pump 21 are both connected to the controller 4. The controller 4 is configured as follows:

[0064] Obtaining a preset pressure threshold and a current water pressure detected by the water pressure sensor 222;

[0065] When the current water pressure is less than the preset pressure threshold, the water pumping pressure of the water pump 21 is increased until the current water pressure is greater than the preset pressure threshold.

[0066] It should be noted that the pressure reducing valve 223 in this embodiment is located between the water circuit switch valve 221 and the water pressure sensor 222, and the water circuit switch valve 221 and the water pressure sensor 222 are located at the lowest point of the water supply system 2 in the vertical direction. In the case of drainage, it can ensure that the residual water in the water supply system 2 is completely discharged. In this embodiment, the current water pressure in the main water supply path 22 can be detected in real time by the water pressure sensor 222. When the water pressure is less than the preset pressure threshold, the pumping pressure of the water pump 21 is increased by the controller 4. After the water pressure is increased, the pressure is reduced by the pressure reducing valve 223, forming a water pressure filtering adjustment method in which the water pressure first rises and then falls, which can make the pressure stable and controllable.

[0067] In one embodiment, a flow meter 224 and a stop valve 225 are provided on the water supply main line 22. The flow meter 224 is provided between the water pump 21 and the stop valve 225. The flow meter 224 and the stop valve 225 are both connected to the controller 4. The controller 4 is configured as follows:

[0068] Obtaining a preset flow range and a current flow detected by the flow meter 224;

[0069] When the current flow rate is not within the preset flow rate range, the stop valve 225 is adjusted until the current flow rate is within the preset flow rate range.

[0070] The flow meter 224 in this embodiment can detect the current flow in the water supply main path 22 in real time. The flow meter 224 can be located between the water circuit switch valve 221 and the stop valve 225. The stop valve 225 in this embodiment can be a proportional valve. When the controller 4 determines through the flow meter 224 that the current flow is not within the preset flow range, the stop valve 225 can be adjusted to achieve water flow control in the water supply main path 22. Finally, the water supply main path 22 is connected to the water supply port of the mixing drum 34 so that water can enter the mixing drum 34 stably and continuously. The water supply system 2 in this embodiment can achieve quantitative water addition to the mixing drum 34, and can also achieve water supply for whole machine cleaning, as well as exhaust and drainage of the water supply system 2. The water supply system 2 in this embodiment is independently controllable. The controller 4 can start and stop adding water to the mixing drum 34 by controlling the water circuit switch valve 221.

[0071] In other embodiments, the controller 4 can also cut off the power to the stirring assembly and the water pump 21 through the shutdown pressure threshold and the current water pressure detected by the water pressure sensor 222, and control the stirring assembly and the water pump 21 to stop, so as to achieve the synchronous stop of the stirring assembly and the water pump 21, and avoid the situation of stirring when the water pressure is insufficient, thereby ensuring the mixing quality of the mortar. The controller 4, the flow meter 224 and the stop valve 225 cooperate to realize the controllable water addition amount of the stirring drum 34, and the stop valve 225 adjusts the water amount, so that the water supply system 2 is controllable and multiple functions can be realized.

[0072] like Figure 4 As shown, the stirring assembly includes a stirring drive 31 and a stirring shaft 32. The stirring drive 31 is connected to the stirring drum 34 and is located outside the stirring chamber 341. The stirring shaft 32 includes a conveying section with a spiral conveying structure 321 and a stirring section with stirring blades. The conveying section is connected between the stirring drive 31 and the stirring section, and the feed port 12 is arranged corresponding to the conveying section. The stirring drive 31 in this embodiment can use a motor as a driving device. The stirring drive 31 can be connected to the stirring shaft 32 through a coupling. The stirring shaft 32 is placed in the stirring drum 34. The upper part of the stirring shaft 32 is a conveying section with a spiral conveying structure 321, which can realize quantitative conveying. The lower part of the stirring shaft 32 is a stirring section with stirring blades, which can realize the stirring function. The conveying section can convey dry mortar to the stirring drum 34. On the other hand, water is added to the stirring chamber 341 through the water supply port on the stirring drum 34, and under the action of the stirring section, the dry mortar is stirred with water. After stirring, the mortar is conveyed to the mortar pump 33 and pumped out through the mortar pump 33. The mixing drum 34 in this embodiment is in a downwardly inclined structure from the back to the front, and the stirring drive member 31 is located at the top of the mixing drum 34. Through the cooperation of the conveying section and the stirring section, stable output of wet mortar can be achieved.

[0073] In one embodiment, the dry-mix mortar pump 100 further includes a cleaning shaft 5 with a cleaning brush, and the cleaning shaft 5 and the stirring shaft 32 are both used for detachable connection with the stirring drive member 31 .

[0074] In the cleaning condition, the motor end of the mixing drum 34 can be opened, the mixing shaft 32 can be pulled out, the upper cleaning shaft 5 can be replaced on the stirring drive 31, and the motor end of the upper mixing drum 34 can be closed. The cleaning branch 23 of the water supply system 2 is connected to the hopper 1, and the main water supply 22 and the drainage branch 24 are closed. The water pump 21 and the stirring drive 31 are started, and the mortar in the hopper 1, the mixing drum 34, and the mortar pump 33 is cleaned and discharged under the action of the cleaning shaft 5.

[0075] The dry-mix mortar pump 100 in this embodiment is equipped with a cleaning shaft 5 specifically used for cleaning mortar. In addition, there is a cleaning branch 23 in the water supply system 2 for cleaning water supply, which can directly use the water supply system 2 on the equipment without the need for an external water source. When cleaning, it is only necessary to replace the stirring shaft 32 with the cleaning shaft 5, adjust the water channel to the cleaning water, and connect the cleaning port to the hopper 1. After there is a certain amount of water in the hopper 1, turn on the stirring drive 31, and the cleaning shaft 5 will rotate accordingly, and the mortar attached to the hopper wall 1, the mixing drum 34 wall and the mortar pump 33 will be discharged, so as to achieve the purpose of cleaning the equipment.

[0076] It should be noted that the dry-mixed mortar pump 100 also includes a spraying device 6 and an air supply system 7. The spraying device 6 includes an air inlet pipe 61 and a spray gun 63. The mortar inlet of the mortar pump 33 and the spray gun 63 are connected; the air supply system 7 is connected to the spray gun 63 through the air inlet pipe 61, and the air supply system 7 is used to supply air to the spray gun 63 as an air source. The dry-mixed mortar pump 100 in this embodiment integrates a water supply system 2, an air supply system 7, a stirring assembly, a spraying device 6 and a controller 4, which can realize the functions of adding water, stirring, pumping and spraying of dry mortar, and integrate the functions of adding water, stirring, pumping and spraying of wet mortar into one device. The controller 4 can control the start and stop of the equipment, and can also control the water circuit components of the water supply system 2 and the air circuit components of the air supply system 7, to realize the control of the water supply system 2 and the air supply system 7, and ensure the stable and controllable operation of the equipment. According to the air circuit principle, the spray gun 63 and the air inlet pipe 61 are connected, and then one end of the mortar pipe 331 is connected to the outlet joint of the mortar pump 33, and the other end of the mortar pipe 331 is connected to the mortar inlet on the spray gun 63. After starting the dry-mix mortar pump 100, open the spray gun 63, and the mortar can be sprayed out from the nozzle of the spray gun 63.

[0077] In one embodiment, if Figure 6As shown, the air supply system 7 includes an air compressor 71 and a spray gun 63 air pipe with an air pressure sensor 72 which are connected in sequence. The air compressor 71 is connected to the air inlet pipe 61 through the spray gun 63 air pipe. The air inlet pipe 61 is provided with an air valve 62 for opening or closing the air inlet pipe 61. The mortar mixing pump 33 also includes a one-touch start button. The one-touch start button, the air pressure sensor 72, and the air compressor 71 are all connected to the controller 4. The controller 4 is configured as follows:

[0078] Make sure the one-touch start button is in the start state;

[0079] Obtaining a preset low pressure threshold, a preset high pressure threshold, and the current air pressure detected by the air pressure sensor 72, wherein the preset high pressure threshold is greater than the preset low pressure threshold;

[0080] When the current air pressure is lower than the preset high pressure threshold, the air compressor 71 is started;

[0081] When the current air pressure is lower than the preset low pressure threshold, the mortar pump 33 and the water supply system 2 are started;

[0082] When the current air pressure is higher than the preset high pressure threshold, the air compressor 71, the mortar pump 33 and the water supply system 2 are controlled to enter the standby state.

[0083] The air passes through the air compressor 71 and enters the air pressure sensor 72, and then reaches the spray gun 63 through the spray gun 63 air pipe and the air inlet pipe 61, serving as the air source for spraying mortar. The operator can start and stop the dry-mix mortar pump 100 by operating the one-touch start button. After the operator starts the dry-mix mortar pump 100 by operating the one-touch start button, when the spraying operation needs to be suspended, the operator only needs to close the air valve 62 on the spray gun 63 nearby, and there is no need to operate the one-touch start button again. At this time, the air pressure in the intake pipe 61 begins to rise. When the current air pressure in the intake pipe 61 is higher than the preset high-pressure threshold, the controller 4 controls the air compressor 71, the mortar pump 33 and the water supply system 2 to enter the standby state to achieve remote shutdown; when the spraying operation is needed again, it is only necessary to open the air valve 62 on the spray gun 63 nearby. At this time, the air pressure in the air pipe begins to drop. When the current air pressure in the intake pipe 61 is lower than the preset high-pressure threshold, the air compressor 71 is started. When the current air pressure in the intake pipe 61 is lower than the preset low-pressure threshold, the mortar pump 33 and the water supply system 2 are started to achieve remote start of the machine. The air supply system 7 in this embodiment is safe and controllable, and not only provides an air source for spraying; the air pressure sensor 72 configured in the air circuit can realize the remote start and stop of the machine, greatly facilitating on-site construction operations; and the entire air supply system 7 does not need to be equipped with a gas tank, and the air circuit is stabilized by the air compressor 71, which greatly reduces the volume of the air supply system 7.

[0084] like Figures 1 to 3As shown, the dry-mix mortar pump 100 also includes a frame 8 with a caster structure 81, and the water supply system 2 and the mixing drum 34 are both installed on the frame 8. The water supply system 2, the air supply system 7, the controller 4, the mixing drum 34, the one-touch start button and the hopper 1 are fixed on the frame 8. The mortar pipe 331 in this embodiment can be a hose, and the spray gun 63 is connected through the mortar pipe 331 to realize remote mortar spraying. The water supply system 2 can stabilize the water flow and realize controllable, continuous and stable water supply to the mixing drum 34. The frame 8 has a caster structure 81, and all systems are installed on the frame 8, which can realize the overall movement of the whole machine with high integration. The controller 4 can be installed on the back side of the frame 8 to control the water pressure of the water supply system 2 to be stable, the air pressure of the air supply system 7 to be stable and continuous, and can realize the start / stop / reset function of the whole machine.
