DETAILED DESCRIPTION

[0028] See also Figure 1-4 A caulking machine for construction comprises a base 1, movable wheels 2 are arranged on the four corners of the bottom of the base 1, a storage box 3 is arranged on the top of the base 1, a stirring assembly 4 is arranged in the storage box 3, a mounting plate 5 is integrally connected to the end of the base 1 away from the storage box 3, a cleaning assembly 6 for cleaning the gap is arranged at the bottom of the mounting plate 5, a mounting block 7 is fixedly connected to the top of the end of the top of the mounting plate 5 away from the base 1, a rotating shaft 8 is rotatably connected to the mounting block 7 through a damping bearing, a telescopic assembly 9 is fixedly sleeved on the outer side of the rotating shaft 8, a nozzle 10 is symmetrically arranged on the top of the telescopic assembly 9, and the storage box 3 and the nozzle 10 are communicated through a feeding assembly 11.

[0029] When working, first, the operator uses the moving wheels 2 on the four corners of the bottom of the base 1 to easily push the caulking machine to the construction site and align it with the gap that needs to be caulked; then the cleaning component 6 is started, and the cleaning component 6 cleans the debris, dust, etc. in the gap to create a clean environment for caulking, thereby improving the quality and firmness of the caulking; at the same time, the stirring component 4 in the storage box 3 is started to fully stir the materials required for caulking to ensure that the material texture is uniform and the components are fully mixed to achieve the best caulking effect.

[0030] Then, the feeding assembly 11 is turned on to draw the mixed material from the storage box 3 and transport it to the nozzle 10, and finally spray it out from the nozzle 10; in this process, the telescopic assembly 9 can be adjusted according to the position and depth of the gap to ensure that the nozzle 10 can accurately fill the material into the gap, and the rotating shaft 8 rotatably connected to the mounting block 7 through the damping bearing can flexibly adjust the angle of the telescopic assembly 9 and the nozzle 10 to adapt to gaps in different directions and positions.

[0031] With this design, firstly, the rotating shaft 8 rotatably connected to the telescopic component 9 and the mounting block 7 through the damping bearing enables the nozzle 10 to be precisely adjusted according to the position, depth and angle of the gap, which not only ensures that the material accurately and fully fills the gap, reduces material waste, and improves the accuracy and quality of caulking, but also can adapt to gaps in various directions and positions. No matter whether it is a complex construction environment or gaps of different shapes, sizes and depths, the caulking work can be completed smoothly, thereby expanding the scope of application of the caulking machine.

[0032] Secondly, the cleaning component 6 cleans the debris and dust in the gap before caulking, which can significantly improve the quality and firmness of the caulking and reduce the problems of loose caulking and cracking caused by impurities;

[0033] The stirring component 4 again mixes the caulking material in the storage box 3 sufficiently and evenly to avoid uneven distribution of components, so that the performance of the caulking material reaches the best, thereby enhancing the stability and durability of the caulking effect.

[0034] In addition, the movable wheels 2 arranged at the four corners of the bottom of the base 1 enable the caulking machine to be easily moved on the construction site without being restricted by the site, which greatly improves the flexibility and efficiency of the construction and saves time and energy for manual handling.

[0035] The telescopic assembly 9 includes a fixed rod 91 , in which a square slide groove 92 is provided, and in which a rectangular telescopic rod 93 is slidably connected.

[0036] The rectangular telescopic rod 93 is provided with a thread groove 94 , and the thread groove 94 is arranged along the height direction of the axis of the rectangular telescopic rod 93 .

[0037] The threaded groove 94 is internally threadedly connected with a threaded rod 95 , and the bottom end of the threaded rod 95 is transmission-connected with a driving motor 96 , which is fixedly installed at the bottom of the slide groove 92 .

[0038] When the drive motor 96 is started, the drive motor 96 starts to run and drives the threaded rod 95 connected to it to rotate. Since the threaded rod 95 is threadedly connected to the thread groove 94 in the rectangular telescopic rod 93, and the rectangular telescopic rod 93 slides in the slide groove 92 in the fixed rod 91, the rectangular telescopic rod 93 is restricted by the slide groove 92 and cannot rotate with the threaded rod 95, and can only move linearly along the slide groove 92.

[0039] When the threaded rod 95 rotates clockwise, the rectangular telescopic rod 93 will extend upward along the slide groove 92 under the push of the thread; when the threaded rod 95 rotates counterclockwise, the rectangular telescopic rod 93 will retract downward along the slide groove 92; the threaded rod 95 is controlled by driving the motor 96 to rotate forward and reverse, so as to realize the telescopic action of the rectangular telescopic rod 93 in the fixed rod 91, thereby achieving the purpose of telescopic adjustment, and then quickly and accurately adjusting the position of the nozzle 10.

[0040] The cleaning assembly 6 includes a cleaning box 61 fixedly mounted on the bottom of the mounting plate 5 , a plurality of fans 62 are arranged on the top inner wall of the cleaning box 61 , and a filter screen 63 is arranged in the cleaning box 61 and below the fans 62 .

[0041] An air outlet is provided on one side wall of the cleaning box 61 and above the filter screen 63 .

[0042] A dust collecting box 64 is slidably disposed at the bottom of the cleaning box 61 , and a handle 69 is fixedly mounted on one side of the dust collecting box 64 away from the cleaning box 61 .

[0043] Support shafts 65 are symmetrically fixedly disposed on both side walls of the cleaning box 61 . The other end of the support shaft 65 is connected to a connecting plate 66 via a damping bearing. A dust cover 67 is disposed between the two connecting plates 66 .

[0044] The top of the dust hood 67 is fixedly connected with a plurality of dust pipes 68 , and the other end of the dust pipe 68 away from the dust hood 67 is fixedly passed through the dust collecting box 64 and extends to the inner side thereof. The dust pipe 68 is a telescopic tube.

[0045] When performing the gap cleaning operation, the multiple fans 62 on the top inner wall of the cleaning box 61 are started. The fans 62 generate suction force, so that negative pressure is formed around the dust hood 67. Due to the effect of negative pressure, dust, debris, etc. in the gap are sucked into the dust hood 67. Subsequently, the dust and debris are transported to the dust collection box 64 along the dust collection pipe 68 fixedly connected to the top of the dust hood 67.

[0046] Then, when dust and debris pass under the fan 62, the filter 63 comes into play to block larger particles and impurities and prevent them from entering the fan 62, thereby protecting the fan 62. The filtered air is discharged from the air outlet opened on the side wall of the cleaning box 61 above the filter 63.

[0047] As the cleaning work continues, the dust in the ash box 64 gradually accumulates. When the ash box 64 needs to be cleaned, the operator pulls the handle 69 fixed on one side of the ash box 64 to slide the ash box 64 out from the bottom of the cleaning box 61 to handle the dust and debris in the ash box 64.

[0048] When cleaning gaps at different positions and angles, the angle and position of the dust hood 67 can be flexibly adjusted through the support shafts 65 symmetrically fixed on the two side walls of the cleaning box 61 and the connecting plate 66 connected to the other end of the support shaft 65 through a damping bearing, ensuring that dust and debris in the gaps can be effectively sucked out.

[0049] With this design, firstly, the dust hood 67 can flexibly adjust the angle and position, so that it can be accurately aimed at the caulking place, and the dust generated during the caulking process can be efficiently sucked in, ensuring the cleanliness of the caulking area; secondly, the multiple fans 62 provide strong suction, which can suck out dust from deep into the gap to avoid dust residue affecting the caulking effect and quality; then the dust suction tube 68 guides the dust into the dust collecting box 64, and the sliding dust collecting box 64 is equipped with a handle 69, which is convenient for timely cleaning of the collected dust to avoid dust flying again and affecting the caulking operation; thereby keeping the caulking area clean, helping the caulking material to better fill the gap, improving the tightness and firmness of the caulking, and ensuring the quality of the caulking.

[0050] In addition, the filter 63 below the fan 62 can block dust, make the exhausted air clean, reduce dust pollution in the construction environment, and create a good environment for caulking work.

[0051] The stirring assembly 4 includes a stirring shaft 41 rotatably disposed in the material storage box 3 , stirring rods 43 are evenly distributed on the stirring shaft 41 , and a plurality of through holes 44 are evenly penetrated through the stirring rods 43 .

[0052] One end of the stirring shaft 41 is rotatably connected to the inner wall of the bottom of the storage box 3, and the other end of the stirring shaft 41 passes through the storage box 3 and is transmission-connected to a stirring motor 42, which is fixedly mounted on the outer wall of the storage box 3.

[0053] When the material in the storage box 3 needs to be stirred, the stirring motor 42 is started, and the stirring motor 42 runs and drives the stirring shaft 41 connected thereto to rotate; as the stirring shaft 41 rotates, the stirring rods 43 evenly arranged thereon also rotate accordingly, and during the rotation of the stirring rods 43, the material in the storage box 3 is stirred to be evenly mixed.

[0054] The plurality of through holes 44 uniformly penetrated through the stirring rod 43 facilitates the flow and exchange of materials during the stirring process, further improving the stirring effect and enabling the materials to be fully mixed.

[0055] This design allows the caulking material to be fully and evenly mixed to avoid uneven distribution of components, thereby ensuring the stable performance of the caulking material and improving the caulking quality.

[0056] The top of the material storage box 3 is fixedly connected with a feeding pipe 12 , and the top of the feeding pipe 12 is plugged with a sealing cover 13 .

[0057] With such a design, the sealing cover 13 can be set to not only seal the feeding pipe 12 during the non-feeding period, effectively preventing external impurities, dust and other pollutants from entering the storage box 3 to ensure the purity of the material; but also prevent the material from accidentally spraying or splashing out of the feeding pipe 12 to cause harm to the operator.

[0058] The feeding assembly 11 includes a feeding pump 111 fixedly mounted on the top of the base 1 . A feeding end of the feeding pump 111 is fixedly connected to a feeding pipe 112 , and the other end of the feeding pipe 112 is connected to the storage box 3 .

[0059] The discharge end of the feed pump 111 is fixedly connected to two discharge pipes 113 , the other end of the discharge pipe 113 is connected to the corresponding nozzle 10 , and the discharge pipe 113 is a telescopic pipe.

[0060] The discharge pipe 113 is provided with a valve 114 for controlling the on-off of the discharge pipe 113 .

[0061] When the caulking operation begins, the feed pump 111 is started, and the feed pump 111 extracts the caulking material from the storage box 3 through the feed pipe 112. Since the feed pipe 112 is connected to the storage box 3, under the suction of the feed pump 111, the material enters the feed pipe 112 from the storage box 3, and then enters the feed pump 111. After the feed pump 111 pressurizes the extracted material, the corresponding valve 114 is opened at this time, and the material is transported out through the discharge pipe 113 at the discharge end. Since the discharge pipe 113 is a telescopic pipe, the length can be adjusted according to the actual caulking position and demand. The material finally passes through the discharge pipe 113 to the corresponding nozzle 10 and is sprayed out from the nozzle 10, completing the conveying process of the caulking material.

[0062] With this design, firstly, the feed pump 111 can provide stable and powerful power to ensure that the caulking material is quickly and continuously delivered from the storage box 3 to the nozzle 10, thereby improving the construction efficiency; secondly, the output amount of the caulking material can be accurately controlled by adjusting the working parameters of the feed pump 111, such as pressure and flow, so that the caulking effect is more uniform and accurate; thirdly, the discharge pipe 113 in the form of a telescopic tube is flexible and can adapt to the caulking needs of different distances and angles, thereby expanding the working range of the caulking machine.

[0063] A push handle 14 is fixedly mounted on one end of the base 1 close to the storage box 3 .

[0064] This design provides the operator with a convenient force point, allowing him to easily push the caulking machine to move.

[0065] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
