[0030] The main body 1 of the mortar spraying machine drives the mortar to be transported and sprayed. The above is the prior art and will not be elaborated below. The mortar feeding box 2 is connected to the outer wall of the main body 1 of the mortar spraying machine. The mortar feeding box 2 can store the mortar, so as to continuously drive the mortar to be transported through the main body 1 of the mortar spraying machine. The filter screen 3 is arranged above the mortar feeding box 2, and the periphery of the filter screen 3 is connected by bolts, which can filter the mortar to prevent the stones mixed inside from falling into the main body 1 of the mortar spraying machine.

[0031] The blockage clearing mechanism 4 is arranged below the filter screen 3. The blockage clearing mechanism 4 can clean the stones in the mesh holes of the filter screen 3, so as to enable the mortar to quickly pass through the mesh holes of the filter screen 3. The blockage clearing mechanism 4 includes limit blocks 401 fixedly arranged at both ends above the mortar feeding box 2. The limit blocks 401 are connected by bolts, which can play a role in limiting the internal structure during vertical movement. And there are holes opened at both ends above the limit blocks 401, which can provide stable vertical movement for the internal structure. A connecting shaft 402 is vertically slidably connected in the holes of the limit blocks 401. The connecting shaft 402 can drive the structure connected to the bottom to move synchronously during the vertical movement process. A slide rail 403 welded to the bottom of the connecting shaft 402. The slide rail 403 can stably move vertically synchronously through the connecting shaft 402. And there are through holes opened on the slide rail 403, which can provide stable vertical movement for the internal structure.

[0032] A spring 404 sleeved on the connecting shaft 402. The spring 404 can perform vertical extrusion work through its own elastic force. And both ends of the spring 404 are respectively attached to the inner wall of the limit block 401 and the outer wall of the slide rail 403. The spring 404 can drive the lower slide rail 403 to reset to its original position during the extrusion process. A first handle 405 welded to the top end of the connecting shaft 402. The first handle 405 can be held by a worker to drive the connecting shaft 402 connected to one end to move. And the cross-sectional shape of the first handle 405 is "U" shaped, which can provide comfort for the worker during the holding process. A fixing plate 406 horizontally slidably connected inside the slide rail 403. There are holes opened inside the fixing plate 406, which can provide for the mortar to be conveyed downward through the holes. A convex block 407 welded above the fixing plate 406. The size of the convex block 407 is adapted to the mesh holes of the filter screen 3, so as to provide blockage clearing work when the convex block 407 is inserted into the mesh holes of the filter screen 3. The discharge head 5 is connected to the bottom of the mortar feeding box 2 for spraying the mortar. The spraying mortar machine main body 1 can drive the mortar to be sprayed through the discharge head 5, and the discharge head 5 can be connected to a pipeline.

[0033] Filter the mortar through the filter screen 3 and then transport it to the inside of the mortar feeding box 2 for temporary storage. Starting the main body 1 of the mortar spraying machine can drive the mortar inside the mortar feeding box 2 to be ejected through the discharge head 5. When the inside of the mesh holes of the filter screen 3 becomes blocked, hold the first handle 405 and move it vertically upward. At this time, during the movement of the first handle 405, it will drive the slide rail 403 connected to the lower part of the connecting shaft 402 to move synchronously. The slide rail 403 can stably move vertically inside the limit block 401. During the movement of the slide rail 403, it can synchronously drive the bump 407 on the fixed plate 406 inside to move. When the bump 407 touches the inside of the mesh holes of the filter screen 3, it will push the stones inside the mesh holes of the filter screen 3 out. After the cleaning is completed, through the extrusion of the spring 404, the slide rail 403 is driven to reset to its original position.

[0034] Embodiment 2

[0035] Please refer to Figures 1-4 , this embodiment provides a technical solution: a mortar spraying machine, including: a second handle 408, a circular groove 409 and a circular rod 410;

[0036] The second handle 408 welded to both ends of the fixed plate 406 can be held by a worker to drive the fixed plate 406 connected to one end to move. And the cross-sectional shape of the second handle 408 is "U" shaped, which can provide comfort for the worker during holding. The circular groove 409 opened above the fixed plate 406 can provide a structure inside to be inserted for subsequent fixing work. And the size of the circular groove 409 matches the size of the through hole on the slide rail 403, which can provide stable movement of the structure inside. The circular rod 410 penetrating through the through hole inside the slide rail 403, and the bottom of the circular rod 410 is inserted into the circular groove 409 inside. After the circular rod 410 is inserted into the circular groove 409, the fixed plate 406 can be fixed inside the slide rail 403.

[0037] When it is necessary to clean the fixed plate 406 regularly, hold the circular rod 410 and move it vertically. At this time, the circular rod 410 no longer continues to be stuck inside the circular groove 409 above the fixed plate 406. At this time, hold the second handle 408 and the fixed plate 406 can be driven to move horizontally inside the slide rail 403, so as to take it out for cleaning.

[0038] The implementation principle of a mortar spraying machine of this application is as follows:

[0039] First of all, filter the mortar through the filter screen 3 and then transport it to the inside of the mortar feeding box 2 for temporary storage. Starting the main body 1 of the mortar spraying machine can drive the mortar inside the mortar feeding box 2 to be ejected through the discharge head 5.

[0040] Secondly, when a blockage occurs inside the mesh holes of the filter screen 3, hold the first handle 405 and move it vertically upward. At this time, during the movement of the first handle 405, it will drive the slide rail 403 connected to the lower part of the connecting shaft 402 to move synchronously. The slide rail 403 can stably move vertically inside the limit block 401. During the movement of the slide rail 403, it can drive the bump 407 on the fixing plate 406 inside it to move synchronously. When the bump 407 contacts the mesh holes of the filter screen 3, it will push the stones inside the mesh holes of the filter screen 3 out. After the cleaning is completed, through the extrusion of the spring 404, the slide rail 403 will be driven to reset to its original position.

[0041] Finally, when it is necessary to regularly clean the fixing plate 406, hold the round rod 410 and move it vertically. At this time, the round rod 410 no longer continues to be engaged inside the round groove 409 above the fixing plate 406. At this time, hold the second handle 408 and it can drive the fixing plate 406 to move horizontally inside the slide rail 403, so as to take it out for cleaning.
