Description

Technical Field

[0001] The utility model relates to the technical field of mortar spraying, and particularly relates to a crack-resistant and protective mortar spraying machine. Background Art

[0002] Gypsum mortar is a building material mixed by gypsum, aggregate and additives. It is mainly used for wall plastering, leveling and crack repair, etc. Gypsum mortar is not only suitable for interior and exterior wall plastering and repair, but also widely used in various building occasions to provide a solid protective layer for buildings.

[0003] According to the Chinese patent with the publication number: CN210459891U, a gypsum mortar spraying machine is disclosed, which includes a frame, a spraying box arranged on the frame, a loading hopper arranged on the spraying box and communicated with the spraying box, and a filter screen. An installation frame covering the feeding port of the loading hopper is arranged on the loading hopper. A placing groove for placing the filter screen is opened on the installation frame. A pressing frame is rotatably connected to the groove wall of the placing groove. A fixing component for fixing the free end of the pressing frame to press the edge of the filter screen is arranged on the installation frame. The filter screen can filter the mortar falling into the transfer hopper. When the filter screen is damaged, rotate the pressing frame to make its free end away from the installation frame, so as to facilitate taking out the filter screen from the placing groove. After replacing the filter screen in the placing groove, rotate the pressing frame to press it on the filter screen, and then fix the free end of the pressing frame on the installation frame through the fixing component, so as to facilitate replacing the damaged filter screen, and the operation is simple.

[0004] The above solution still has the following deficiencies. During the mixing process of the mortar, an anti-cracking agent is not added, which reduces the anti-cracking performance and durability of the gypsum mortar and shortens the service life of the gypsum mortar. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a crack-resistant and protective mortar spraying machine to solve the problem that during the mixing process of the mortar, an anti-cracking agent is not added, which reduces the anti-cracking performance and durability of the gypsum mortar and shortens the service life of the gypsum mortar.

[0006] To achieve the above utility model purpose, the utility model adopts the following technical scheme: a crack-resistant and protective mortar spraying machine includes a control box. A loading hopper is fixed at the front end of the control box. A mixing box is fixed at the bottom surface of the loading hopper. The inside of the loading hopper and the mixing box is communicated. A funnel is fixed on the top surface of the mixing box. The bottom surface of the funnel is communicated with the inside of the mixing box. A current-limiting net is fixed inside the funnel. A scale is arranged on the inner wall surface of the funnel.

[0007] Preferably, a stirring rod is provided at the rear end of the stirring tank, a driving motor is provided inside the control box, and one end of the stirring rod is connected to the output end of the driving motor.

[0008] Preferably, a discharge port is provided at the front end of the stirring tank, and a spray head is inserted inside the discharge port.

[0009] Preferably, a filter screen plate is detachably provided on the top surface of the loading hopper. Two fixing holes are provided on the top surface of the filter screen plate. Two threaded grooves are provided on the top surface of the loading hopper. Bolts are sleeved inside the fixing holes, and the threaded ends of the bolts are threadedly connected to the inside of the threaded grooves.

[0010] Preferably, control buttons are provided on the top surface of the control box, and the control buttons are electrically connected to the driving motor.

[0011] Preferably, a push handle is fixed at the rear end of the control box, a bracket is fixed at the front end of the control box, and four universal wheels are fixed to the bottom surface of the control box and the bracket.

[0012] Compared with the prior art, a crack-resistant protective mortar spraying machine adopting the above technical scheme has the following beneficial effects:

[0013] 1. During use, the staff pours a certain amount of gypsum mortar into the loading hopper, and then pours the crack-resistant agent into the funnel. The ratio of the crack-resistant agent to the gypsum mortar is the ratio that makes the gypsum mortar achieve the best crack-resistant effect. The staff calculates the capacity of the crack-resistant agent according to this ratio. Since a scale is provided on the inner wall surface of the funnel, when the capacity of the crack-resistant agent reaches the optimal capacity, the staff stops pouring the crack-resistant agent, and then starts the driving motor through the control button. Under the rotation of the driving motor, the stirring rod starts to rotate inside the stirring tank. Since the funnel is connected to the inside of the stirring tank, the crack-resistant agent can fall into the inside of the stirring tank. Under the action of the stirring rod, since the loading hopper and the stirring tank are connected, the gypsum mortar in the stirring tank will be oscillated and mixed with the crack-resistant agent. After a period of time, the staff can spray the gypsum mortar mixed with the crack-resistant agent onto the required area through the spray head. And because a current-limiting net is provided inside the funnel, the crack-resistant agent drops into the stirring tank at a certain speed. Therefore, during the spraying process by the staff, the gypsum mortar in this area starts to move towards the inside of the stirring tank and is mixed with the crack-resistant agent, so that all the gypsum mortar can be fused with the crack-resistant agent to achieve the crack-resistant effect. By providing a current-limiting funnel, the crack-resistant agent can be added during the mortar stirring process, so the gypsum mortar can effectively resist the generation of shrinkage cracks during the curing process, significantly improve the overall crack-resistant performance of the mortar, and also improve the service life of the gypsum mortar, providing lasting and stable protection for the building;

[0014] Second, during use, since a filter screen plate is fixed to the top surface of the loading hopper by bolts, when the staff pours gypsum mortar into the loading hopper, under the action of the filter screen plate, some impurities in the gypsum mortar can be filtered out, preventing these impurities from clogging the nozzle during the spraying of the gypsum mortar, and also improving the spraying quality of the gypsum mortar. When it is necessary to clean the filter screen plate, the staff can screw out the bolts to separate the bolts from the threaded grooves. At this time, the staff can take out the filter screen plate from the top surface of the loading hopper and clean the filter screen plate, improving the convenience of the device. Since four universal wheels are fixed to the bottom surface of the control box and the bracket, the staff can push the push handle to move the device to the required area. The universal wheels can rotate through their rotating shafts to change the rolling direction of the tires, so as to more flexibly respond to different ground conditions and steering requirements, reducing the friction and bumps generated by turning and improving the flexibility of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will describe in detail the preferred embodiments of the present invention with reference to the accompanying drawings.

[0021] As Figures 1-3 shown, a crack-resistant protective mortar spraying machine includes a control box 1, a loading hopper 2 is fixed to the front end of the control box 1, a mixing tank 3 is fixed to the bottom surface of the loading hopper 2, the interiors of the loading hopper 2 and the mixing tank 3 are connected, a funnel 4 is fixed to the top surface of the mixing tank 3, the bottom surface of the funnel 4 is connected to the interior of the mixing tank 3, a current-limiting net 5 is fixed inside the funnel 4, a scale 6 is provided on the inner wall surface of the funnel 4, a stirring rod 7 is provided at the rear end of the mixing tank 3, a drive motor 8 is provided inside the control box 1, one end of the stirring rod 7 is connected to the output end of the drive motor 8, a discharge port 9 is opened at the front end of the mixing tank 3, and a nozzle 10 is inserted into the interior of the discharge port 9.

[0022] In use, the staff pours a certain amount of gypsum mortar into the loading hopper 2, and then pours the crack inhibitor into the funnel 4. The ratio of the crack inhibitor to the gypsum mortar is the ratio that makes the anti-cracking effect of the gypsum mortar the best. The staff calculates the capacity of the crack inhibitor according to this ratio. Since the inner wall surface of the funnel 4 is provided with a scale table 6, when the capacity of the crack inhibitor reaches the optimal capacity, the staff stops pouring the crack inhibitor. Then, the driving motor 8 is started through the control button 15. Under the rotation of the driving motor 8, the stirring rod 7 starts to rotate inside the mixing tank 3. Since the funnel 4 is connected to the inside of the mixing tank 3, the crack inhibitor can fall into the inside of the mixing tank 3. Under the action of the stirring rod 7, since the loading hopper 2 and the mixing tank 3 are connected, the gypsum mortar in the mixing tank 3 will be shaken and mixed with the crack inhibitor. After a period of time, the staff can spray the gypsum mortar mixed with the crack inhibitor onto the required area through the nozzle 10. And because a flow-limiting net 5 is arranged inside the funnel 4, the crack inhibitor falls into the mixing tank 3 at a certain speed. So at the beginning, during the spraying process by the staff, the gypsum mortar in this area starts to move into the inside of the mixing tank 3 and is mixed with the crack inhibitor, so that all the gypsum mortar can be fused with the crack inhibitor to achieve the anti-cracking effect. By setting the flow-limiting funnel 4, the crack inhibitor can be added during the mixing of the mortar, so the gypsum mortar can effectively resist the generation of shrinkage cracks during the curing process, significantly improve the overall anti-cracking performance of the mortar, and also improve the service life of the gypsum mortar, providing lasting and stable protection for the building.

[0023] As Figure 1 and Figure 4 shown, a filter plate 11 is detachably arranged on the top surface of the loading hopper 2. A filter plate 11 is detachably arranged on the top surface of the loading hopper 2. Two fixing holes 12 are opened on the top surface of the filter plate 11. Two threaded grooves 13 are opened on the top surface of the loading hopper 2. Bolts 14 are sleeved inside the fixing holes 12. The threaded ends of the bolts 14 are threadedly connected to the inside of the threaded grooves 13. A control button 15 is arranged on the top surface of the control box 1. The control button 15 is electrically connected to the driving motor 8. A push handle 16 is fixed to the rear end of the control box 1. A support 17 is fixed to the front end of the control box 1. Four universal wheels 18 are fixed to the bottom surfaces of the control box 1 and the support 17.

[0024] In use, since the filter screen plate 11 is fixed to the top surface of the loading hopper 2 by bolts 14, when the staff pours gypsum mortar into the loading hopper 2, some impurities in the gypsum mortar can be filtered out under the action of the filter screen plate 11, preventing these impurities from clogging the nozzle 10 during the spraying of the gypsum mortar and improving the spraying quality of the gypsum mortar. When it is necessary to clean the filter screen plate 11, the staff can screw out the bolts 14 to separate the bolts 14 from the threaded grooves 13. At this time, the staff can take out the filter screen plate 11 from the top surface of the loading hopper 2 and clean the filter screen plate 11, improving the convenience of the device. Since four universal wheels 18 are fixed to the bottom surfaces of the control box 1 and the support 17, the staff can push the push handle 16 to move the device to the required area. The universal wheels 18 can rotate through their rotating shafts to change the rolling direction of the tires, so as to more flexibly respond to different ground conditions and steering requirements, reduce the friction and bumps generated during steering, and improve the flexibility of the device.

[0025] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
