[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] The present invention discloses a handheld electric caulking tool for shale bricks, which comprises a mortar ruler 4 and a caulking gun used in conjunction with each other. The structure of the caulking gun is as follows: Figure 2 As shown, it includes an operating part, a material storage part and a power part.

[0020] Dust Ruler 4 Figure 1 As shown, it is made of stainless steel sheet, the angle between the two folded edges is 90°, the width of one folded edge is 10mm, as a horizontal plate inserted into the brick joint and close to the brick surface, and the width of the other folded edge is 40mm, as a vertical plate close to the outer side of the shale brick in the vertical direction. At the end of the vertical plate, a row of elastic hooks composed of steel wire 3, spring 2, and seam hook 1 are welded along the length direction of the vertical plate, and the spacing between two adjacent elastic hooks is 30cm to 50cm. The function of the dust isolation ruler 4 is to control the depth of the mortar joint to prevent the brick surface outside the mortar joint from being stained with dust.

[0021] like Figure 3As shown, the working part includes a connecting tube 6 and a grouting nozzle 5, a cleaning block 10, and a joint pressing ball 11. The connecting tube 6 is a metal cylindrical tube with a diameter of 50 mm and a height of 30 mm. The left end is sealed with a sealing plate, and the right end is open. The grouting nozzle 5, the cleaning block 10, and the joint pressing ball 11 are installed at one end of the sealing plate. The cleaning block 10 is threadedly connected to the sealing plate at the left end of the connecting tube 6 through a first screw 16. A limit plate 12 is mounted on the first screw 16. The outer dimensions of the limit plate 12 are larger than the dimensions of the brick joint. It is clamped on the outer side of the vertical plate of the dust barrier 4. During the operation and movement of the grouting gun, the limit plate 12 always remains close to the vertical plate of the dust barrier 4. The limit plate 12 is clamped on the first screw 16 by two adjusting nuts 13. The two adjusting nuts 13 are rotated on the first screw 16 to adjust the installation position, so that the depth distance of the caulking finished surface can be adjusted by the limit plate 12. The function of the working part is to firmly fix the working part and the storage part through the fixing nut of the side wall of the connecting tube 6. The position of the limit plate 12 is adjusted to determine the distance between the mortar joint finished surface and the brick surface. The grouting nozzle 5 sprays the caulking agent to fill the brick joint. The cleaning block 10 squeezes the caulking agent and scrapes off the excess caulking agent during the movement of the working part. The pressing ball 11 squeezes the mortar joint to form a dense and smooth arc surface.

[0022] like Figure 2 As shown, the material storage section is a material storage barrel 8 composed of a metal cylindrical barrel with a diameter of 45 mm and a height of 400 mm, and both ends are blocked with sealing plates. A discharge port is arranged at the front sealing plate, and its diameter and length are smaller than the grouting nozzle 5 in the working section. A feeding port 9 is arranged on the outer side of the rear end barrel wall, and the feeding port 9 is opened and closed by screwing the cover. A feeding screw 7 is fixed in the material storage barrel 8, and the tail end of the feeding screw 7 extends from the rear end sealing plate and is connected to the rotating motor in the power section. The function of the material storage section is to store the configured caulking agent, which is added into the metal barrel from the feeding port, and the rotating motor drives the feeding screw 7 to rotate, pushing the caulking agent out of the discharge port.

[0023] like Figure 2 As shown, the power unit is composed of a rotating motor, a battery, and a switch, and the rotor of the rotating motor is connected to the feeding screw 7 of the storage unit. The function of the power unit is to provide power for the feeding screw 7 in the storage unit to rotate, and the rotation and stop of the feeding screw are realized by the control of the switch.

[0024] The mechanical principle of the present invention is simple, the raw materials and accessories are easy to find, and the production and processing are relatively convenient. The present invention is easy to operate, and the operator can start work after a little training. It does not require professional technical workers and has high construction quality; grouting, scraping, pressing seams, and grouting are completed in one go, saving multiple construction processes and greatly improving construction efficiency; an electric device is used for feeding, and the timing of discharging is controlled by a switch, which is flexible to operate and convenient to control; the depth of the grouting is adjusted by a limit piece 12, which has high precision and a beautiful and uniform finished surface; the dust isolation ruler 4 is used as an isolation layer of the operating surface, and the construction accuracy is greatly improved. The dust cleaning block 10 scrapes and presses the excess caulking material, which greatly reduces the use of caulking agent during construction, reduces energy consumption, saves raw materials, and does not need to clean the brick joints after the construction is completed, saving labor, reducing labor intensity, and effectively preventing waste cleaning from polluting the environment.
