The material control sleeve is slidably connected to the left side of the air outlet pipe, and a telescopic spring connects the material control sleeve to the air outlet pipe. The trigger is movably connected to the material control sleeve. A storage container is threadedly connected to the upper middle side of the gun body. A locking valve is rotatably installed on the upper middle side of the gun body, located below the storage container. A feeding assembly capable of controlling the feeding speed is installed on the storage container.

[0006] To further clarify, the gun body is padded.

[0007] To further explain, the sprayer has multiple nozzles on its left side.

[0008] To further explain, the lower part of the trigger is curved.

[0009] To further explain, the locking valve is equipped with a knob.

[0010] To further explain, the feeding assembly includes a screw propeller and a control motor. The screw propeller is rotatably connected inside the storage tank, and the control motor is connected to the upper part of the storage tank. The output shaft of the control motor is connected to the screw propeller.

[0011] The beneficial effects of this utility model are as follows: When too much mortar is sprayed, the excess mortar is scraped off by a paint scraper and flows into the collection bin along the paint scraper. This achieves the effect of conveniently scraping off and collecting excess mortar, improving the quality of mortar spraying, and avoiding mortar waste. Attached Figure Description

Detailed Implementation

[0018] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0019] A mortar spray gun for construction, such as Figures 1-5As shown, it includes a gun body 1, a connecting pipe 2, an air outlet pipe 3, a sprayer 4, a paint scraper 5, a collection bin 6, a trigger 7, a material control sleeve 8, a telescopic spring 9, a locking valve 10, a storage tank 11, and a feeding assembly. The connecting pipe 2 is connected to the lower side of the gun body 1. The gun body 1 is equipped with a soft pad for easy gripping. The air outlet pipe 3 is connected to the upper side of the connecting pipe 2. The air outlet pipe 3 is located inside the gun body 1 and is connected to the gun body 1. The sprayer 4 is connected to the left side of the gun body 1. The sprayer 4 has five nozzles on its left side for easy spraying. The paint scraper 5 is snapped into the lower left side of the sprayer 4. The lower part of the sprayer 4... A collection bin 6 is attached to the gun body 1, located to the right of the paint scraper 5. A trigger 7 is rotatably connected to the middle of the gun body 1. The lower part of the trigger 7 is arc-shaped for easy pulling. A material control sleeve 8 is slidably connected to the left side of the air outlet pipe 3. A telescopic spring 9 is connected between the material control sleeve 8 and the air outlet pipe 3. The trigger 7 and the material control sleeve 8 are movably connected. A storage device 11 is threadedly connected to the upper middle part of the gun body 1. A locking valve 10 is rotatably installed on the upper middle part of the gun body 1. The locking valve 10 has a knob for easy rotation. The locking valve 10 is located below the storage device 11. The storage device 11 is equipped with a feeding assembly.

[0020] like Figure 5 As shown, the feeding assembly includes a screw propeller 12 and a control motor 13. The screw propeller 12 is rotatably connected inside the storage tank 11, and the control motor 13 is connected to the upper part of the storage tank 11. The output shaft of the control motor 13 is connected to the screw propeller 12.

[0021] When using this invention, first connect the air pump's air pipe to the connecting pipe 2, then pour the mortar into the storage container 11. Next, have the operator hold the gun body 1, aim the sprayer 4 at the mortar spraying position, and then pull the trigger 7 to rotate to the right, causing the control sleeve 8 to move to the right. The telescopic spring 9 is compressed, preventing the control sleeve 8 from blocking the material outlet of the storage container 11. Then, rotate the locking valve 10 to open, allowing the mortar to flow into the gun body 1. Simultaneously, start the air pump, allowing air to flow through the air pipe into the air outlet pipe 3, causing the gas to spray out from the control sleeve 8, thus spraying the mortar from the sprayer 4 to the spraying position. After coating, turn the locking valve 10 to close, then release the trigger 7. The telescopic spring 9 returns, causing the material control sleeve 8 to reset and the storage tank 11 to stop discharging. When the mortar is poured into the storage tank 11, the control motor 13 can be started to drive the screw propeller 12 to rotate. The screw propeller 12 controls the mortar discharging speed and stirs the mortar. When too much mortar is sprayed, the excess mortar can be scraped off by the paint scraper 5 and flow into the collection bin 6 along the paint scraper 5. This facilitates the scraping and collection of excess mortar, improves the quality of mortar spraying, and avoids mortar waste.
