Through the coordinated use of a first motor, a rotating rod, a mounting sleeve, a stirring rod, a transport pump, a spray gun, a storage box and a screening assembly, the reciprocating screen will screen the injected mortar and shake and break up the mortar lumps that are easy to disperse, preventing some of the agglomerated mortar from falling directly into the storage box and causing blockage inside the hopper and the storage box. The injected mortar is screened by the reciprocating screen to prevent some of the agglomerated mortar from falling directly into the storage box and preventing the agglomerated mortar from clogging the screen and affecting the injection rate of the mortar. The fallen mortar is fully mixed and kept in a fluid state under the action of multiple rotating stirring rods, so that the transport pump can continuously extract the mortar, thereby improving the continuity of the mortar sprayer during spraying.

[0023] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, they are further elaborated below in conjunction with specific implementation methods.

[0024] A construction mortar spraying machine, see Figures 1 to 3 , including a base 1, a box body 101, a screening plate 17 and a hose 11. The top of the base 1 is fixedly connected to the box body 101. A storage tank 2 is provided on the left side of the box body 101, and a stirring tank 3 is provided on the top of the base 1 on the right side of the storage tank 2. The outer walls of the box body 101 on both sides of the stirring tank 3 are fixedly connected with electric push rods 6. The telescopic end of the electric push rod 6 passes through the outer wall of the box body 101 and is fixedly connected to the crushing splint 7. The center of the inner bottom of the stirring tank 3 is rotatably connected to the crushing stirring rod 8. The inner side of the box body 101 just below the crushing stirring rod 8 is fixedly connected to the second servo motor 801. The mixing tank 3 is divided into two layers, the bottom of the crushing splint 7 fits with the bottom of the upper layer of the mixing tank 3, and the upper and lower connecting parts of the mixing tank 3 are fixedly connected with a receiving net 302. The agglomerated mortar will enter the mixing tank 3 along the inclined direction of the screen plate 17 and be caught by the receiving net 302. Then the electric push rod 6 is started to drive the crushing splint 7 to move toward the center of the mixing tank 3 to crush the agglomerates. The crushed mortar enters the lower layer of the mixing tank 3 and is further crushed under the stirring of the crushing stirring rod 8, so that it can be reused and put into use again, avoiding waste of mortar.

[0025] A transport pump 10 is connected to the bottom opening of the storage trough 2, and the upper and lower ends of the hose 11 are connected to the nozzle 12 and the transport pump 10 respectively. The top of the base 1 on the left side of the box body 101 is fixedly connected to a support frame 13, and the inner side of the support frame 13 is vertically rotatably connected to a threaded rod 14, and the surface of the threaded rod 14 is threadedly connected to a threaded block 15, and the side wall of the threaded block 15 is fixedly connected to a support block 16. The outer surface protrusion of the nozzle 12 is threadedly connected to the surface of the support block 16 by bolts. The nozzle 12 is fixed to the support block 16 by bolts and can move up and down driven by the threaded block 15 to spray at different heights. The bolts can also be removed to manually hold the nozzle 12, which improves the freedom and efficiency of spraying.

[0026] Specifically, such as Figure 2 As shown, the outer surfaces of the box body 101 on the left and right sides of the top of the storage trough 2 are respectively provided with side grooves 4 and outlet grooves 5, and the right end edges of the front and rear surfaces of the screening plate 17 are connected to the front and rear inner wall surfaces of the outlet groove 5 through a rotating shaft. The left end of the screening plate 17 is in an active state and the right end is in a rotating state, so it can be lifted and dropped around a short rotating shaft during vibration.

[0027] It is worth noting that if Figure 2As shown, a rotating rod 401 is rotatably connected between the front and rear inner walls of the side groove 4, and a cam 402 is fixedly connected to the center of the surface of the rotating rod 401. The bottom left surface of the screening plate 17 is in contact with the outer surface of the cam 402. The cam 402 will continuously lift the screening plate 17 during the rotation process, and the screening plate 17 will suddenly fall after being lifted, thereby causing vibration, thereby improving the screening efficiency of the mortar.

[0028] It is worth noting that if Figure 2 As shown, the inner bottom of the mixing tank 3 is connected to the storage tank 2 through the discharge tank 9, and the discharge tank 9 is connected to an electric control valve 901 at the opening of one end close to the mixing tank 3. The slurry after the mixing process flows along the discharge tank 9 into the storage tank 2 and is then put into use, which reduces waste and improves utilization efficiency.

[0029] It is worth noting that if Figure 2 As shown, a water inlet 301 is provided at the right edge of the top of the mixing tank 3. During the mixing process, water can be added according to actual conditions to accelerate the crushing of the mortar. The water inlet 301 can be connected to an external water source for water addition.

[0030] It is worth noting that if Figure 1 and Figure 2 As shown, the outer wall of the box 101 at the horizontal position of the rotating rod 401 is fixedly connected to a servo motor No. 1 403, and the servo motor No. 1 403 is fixedly connected to one end of the rotating rod 401. After the servo motor No. 1 403 is started, it will drive the rotating rod 401 and the cam 402 to rotate, thereby causing the screening plate 17 to vibrate.

[0031] It is worth noting that if Figure 3 As shown, the top of the support frame 13 is fixedly connected to the third servo motor 141, and the outer end of the transmission shaft of the third servo motor 141 is fixedly connected to the top of the threaded rod 14. After the third servo motor 141 is started, it will drive the threaded rod 14 to rotate, causing the threaded block 15 to rise and fall, thereby adjusting the height of the nozzle 12.

[0032] During actual use, the mortar is poured onto the screening plate 17, and the No. 1 servo motor 403 is started, driving the rotating rod 401 and the cam 402 to rotate. During the rotation, the screening plate 17 will be continuously lifted and dropped to vibrate, thereby accelerating the screening of the mortar. The screened mortar enters the bottom of the storage tank 2, and the agglomerated mortar will enter the mixing tank 3 along the inclined direction of the screening plate 17. At this time, the agglomerates are caught by the receiving net 302, and then the electric push rod 6 is started to drive the crushing splint 7 to move toward the center of the mixing tank 3 to crush the agglomerates. The crushed mortar enters the lower layer of the mixing tank 3 and is further crushed under the stirring of the crushing stirring rod 8, so that it can be reused. The mortar can be put back into use again, thereby avoiding waste of mortar and improving utilization efficiency. After the electric control valve 901 is opened, the stirred mortar flows along the discharge trough 9 into the storage tank 2, and finally is sprayed along the hose 11 and the nozzle 12 under the extraction of the transport pump 10 to complete the spraying operation. In this process, the spraying method can be freely selected through the support frame 13, the threaded rod 14, the support block 16 and the nozzle 12. The nozzle 12 is fixed to the support block 16 by bolts and can move up and down under the drive of the threaded block 15 to spray at different heights. The bolts can also be removed to manually hold the nozzle 12 to customize the spraying position, thereby reducing the existence of spraying dead angles and improving the spraying efficiency.
