Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a mortar spraying device for building construction. Background Technology

[0002] In the construction process, mortar spraying is a crucial step, widely used in wall masonry, wall plastering, floor leveling, and surface treatment of special building structures. However, many problems still exist in its practical application.

[0003] Most equipment uses simple single-shaft mixing or has an unreasonable mixing structure design, which cannot mix the mortar in the tank in an all-round and uniform manner. This results in uneven mortar mixing, which affects the subsequent spraying quality and construction effect, and thus reduces the stability and durability of the building structure. During the mortar spraying operation, mortar spillage is inevitable. However, most existing equipment lacks an effective collection device, which not only wastes materials but also makes the construction site dirty and messy. Therefore, we have introduced a mortar spraying device for building construction. Utility Model Content

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This device employs a dual-rotor design with equidistant, horizontally corresponding mixing blades. The dual rotors, driven by a motor, gears, and a synchronous belt, coordinate their operation to create multi-angle, multi-directional mixing paths, covering the entire interior of the mixing chamber and eliminating dead zones. Compared to the limitations of traditional single-shaft mixers that only achieve localized agitation, this design allows the mortar to fully tumble and mix during the mixing process, effectively solving problems such as uneven mortar proportions and segregation, thereby improving the homogeneity and cohesiveness of the mortar.

[0017] 2. This device forms a complete solution through a detachable collection box and a convenient storage structure. The collection box uses a horizontal sliding snap-fit ​​design with clips and slots for easy and quick installation and disassembly. It can collect mortar spilled during high-pressure sandblasting operations in a timely manner, avoiding material waste and reducing construction costs. At the same time, the delivery pipe and nozzle in the device can be stored by snapping the hook on the glove sleeve with the side hole plate. This design saves construction site space and prevents damage or loss caused by random placement of equipment parts, facilitating unified management of construction tools. In addition, the lockable wheels and push handle design make the device easier to move and fix, further improving the continuity of the construction process and the cleanliness of the site, effectively improving the messy and disorderly situation of traditional construction environments.

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] A mortar spraying device for building construction includes a box body 1. A rotating device 10 is fixedly connected to the front right end of the box body 1. A connecting device 6 is fixedly connected to the lower left end of the box body 1. A side perforated plate 9 is fixedly connected to the front left end of the box body 1. A slot 11 is opened on the left front end of the box body 1. A locking block 12 is installed in the slot 11. A collection box 8 is fixedly connected to the left end of the locking block 12. A partition 13 is fixedly connected to the right side of the inner wall of the box body 1.

[0029] The upper end of the box 1 is fitted with a cover plate 3 via a hinge. The upper middle part of the cover plate 3 is fixedly connected to a feed pipe 4. The rear end of the box 1 is fixedly connected to two push handles 2. The lower middle part of the box 1 has a groove 7. Lockable movable wheels 5 are provided at the four corners of the lower end of the box 1.

[0030] The collection box 8 is detachably connected to the box body 1 via a locking block 12. The shape of the locking block 12 is adapted to the slot 11, and the locking block 12 can slide laterally along the slot 11 to achieve the locking.

[0031] In this embodiment, the rotating device 10 includes a drive motor 101 and a second gear block 107. The output shaft of the drive motor 101 passes through the housing 1 and is fixedly connected to a first gear block 102. The outer surface of the first gear block 102 and the outer surface of the second gear block 107 are meshed together by a synchronous belt 106. A short shaft 108 is fixedly connected to the middle of the right end of the second gear block 107. Rotating rods 103 are fixedly connected to the left end of both the second gear block 107 and the left end of the first gear block 102. Several rotating shaft blocks 104 are fixedly connected to the outer surfaces of both rotating rods 103. Several stirring blades 105 are fixedly connected to the outer surface of the shaft block 104. The drive motor 101 is fixedly installed at the front right end of the housing 1. The left ends of the two rotating rods 103 are movably installed on the left side of the housing 1 via bearings. The right end of the short shaft 108 is movably installed on the right side of the housing 1 via a type of bearing. Several stirring blades 105 on the front side and several stirring blades 105 on the rear side are equidistantly distributed in a ring around the rotating rod 103. Several stirring blades 105 on the front side and several stirring blades 105 on the rear side are equidistantly distributed laterally and do not contact the inner wall of the housing 1.

[0032] Through the above scheme: when the drive motor 101 is turned on, its output shaft drives the first gear block 102, which is fixedly connected to it, to rotate. Since the first gear block 102 and the second gear block 107 mesh through the synchronous belt 106, the second gear block 107 also rotates. The rotating rods 103 connected to the left ends of the second gear block 107 and the first gear block 102 start to rotate under their drive. The rotating shaft block 104 on the outer surface of the rotating rod 103 rotates along with it, thereby causing the stirring blades 105 fixed on the rotating shaft block 104 to stir the mortar in the box 1. The left end of the rotating rod 103 is movably mounted on the left box wall of the box 1 through a bearing, and the right end of the short shaft 108 is movably mounted on the right box wall of the box 1 through a bearing, ensuring the stability of the rotation. The stirring blades 105 on the front and rear sides are distributed in a ring with equal spacing around the rotating rod 103, and are also distributed laterally with equal spacing. This layout can thoroughly and evenly stir the mortar in the box 1, making the mortar more fully mixed.

[0033] In this embodiment, the connecting device 6 includes a mounting base 61. A mortar pump 62 is fixedly mounted on the upper end of the mounting base 61. A suction pipe 63 is fixedly mounted on the inlet end of the mortar pump 62 via a flange. A delivery pipe 64 is fixedly mounted on the outlet end of the mortar pump 62 via a flange. A high-pressure sandblasting nozzle 68 is fixedly connected to the other end of the delivery pipe 64. A glove sleeve 66 is sleeved on the side of the delivery pipe 64 away from the mortar pump 62. Two hooks 67 are fixedly connected to the right side of the glove sleeve 66. The mounting base 61 is fixedly connected to the lower left part of the housing 1. The other end of the suction pipe 63 is inserted and installed in the lower middle part of the housing 1. Both hooks 67 are snapped onto the outside of the side hole plate 9.

[0034] With the above solution: when mortar spraying is required, the mortar pump 62 installed on the mounting base 61 is started. Since the suction pipe 63 is connected to the inlet end of the mortar pump 62 through a flange, and the other end of the suction pipe 63 is inserted into the lower middle part of the housing 1, the mortar pump 62 can draw mortar from the housing 1 through the suction pipe 63. After being pressurized by the mortar pump 62, the mortar is transported to the high-pressure sandblasting nozzle 68 through the delivery pipe 64, which is also connected to the outlet end of the mortar pump 62 by a flange. The operator can hold the handle sleeve sleeve attached to the side of the delivery pipe 64 away from the mortar pump 62. 66. Aim the high-pressure sandblasting nozzle 68 at the construction area to spray mortar. When not in use, the two hooks 67 on the right side of the handle sleeve 66 can be attached to the outside of the side orifice plate 9 to store the delivery pipe 64 and the high-pressure sandblasting nozzle 68. The handle sleeve 66 on the delivery pipe 64 makes it convenient for operators to hold and control the spraying direction and range of the high-pressure sandblasting nozzle 68, improving the flexibility and accuracy of construction. At the same time, the snap-fit ​​design of the hooks 67 and the side orifice plate 9 makes it easy to store the delivery pipe 64 and the high-pressure sandblasting nozzle 68 when not in use, saving space and facilitating management.

[0035] It should be noted that this utility model is a mortar spraying device for building construction. When using this mortar spraying device for building construction, the operator can move the device to the construction site by holding the push handle 2 and using the lockable movable wheels 5 set at the four corners of the lower end of the box 1. After arriving, the wheels are locked. Then, the operator can open the cover plate 3 that is hinged to the upper end of the box 1 and add mortar into the box 1 through the feed pipe 4 in the middle of the upper end of the cover plate 3. Start the drive motor 101 of the rotating device 10. The output shaft of the drive motor 101 rotates, driving the first gear block 102 fixedly connected to it to rotate. Since the first gear block 102 and the second gear block 107 are connected by a synchronous belt 1 The gears are meshed together (06), so when the first gear block 102 rotates, it drives the second gear block 107 to rotate synchronously. Both the second gear block 107 and the first gear block 102 have rotating rods 103 fixedly connected to their left ends. The left ends of the two rotating rods 103 are movably mounted on the left wall of the housing 1 via bearings. The right end of the short shaft 108 fixedly connected to the middle of the right end of the second gear block 107 is movably mounted on the right wall of the housing 1 via bearings. Therefore, when the first gear block 102 and the second gear block 107 rotate, they drive the corresponding rotating rods 103 to rotate. Several rotating shaft blocks 104 fixedly connected to the outer surface of the rotating rods 103 also rotate accordingly. Several stirring blades 105 fixedly connected to the outer surface of each rotating shaft block 104... The mixing blades 105 on the front and rear sides are equidistantly distributed in a ring around the rotating rod 103, and are also equidistantly distributed laterally. During rotation, they agitate the mortar in the tank 1, making the mortar uniformly mixed. At the same time, the baffle 13 can play a certain auxiliary and separating role in agitation. When mortar spraying is required, the mortar pump 62 installed on the mounting base 61 of the connecting device 6 is started. The mortar pump 62 draws mortar from the tank 1 through the suction pipe 63 at the inlet end. The other end of the suction pipe 63 is inserted into the middle of the lower end of the tank 1 to facilitate the extraction of mortar from the bottom. After being pressurized by the mortar pump 62, the extracted mortar is transported to the high-pressure sandblasting stage through the delivery pipe 64 at the outlet end. The nozzle 68 is held by the operator by hand, with the sleeve 66 attached to the side of the delivery pipe 64 away from the mortar pump 62. The high-pressure sandblasting nozzle 68 is aimed at the area where mortar needs to be sprayed. The collection box 8 is detachably connected to the slot 11 on the left side of the front end of the box 1 via the locking block 12. The locking block 12 can slide laterally along the slot 11 to achieve the connection, which facilitates the installation and removal of the collection box 8 and makes it easy to clean the collected mortar. When the delivery pipe 64 and the high-pressure sandblasting nozzle 68 are not in use, the two hooks 67 on the right side of the sleeve 66 can be locked to the outside of the side plate 9 to store the delivery pipe 64 and the high-pressure sandblasting nozzle 68. The mortar spilled by the high-pressure sandblasting nozzle 68 can be collected through the collection box 8.
