[0002] The curb caulking device is a device specially used in the field of road engineering technology. Its main function is to fill and compact the gaps between curbs during the curb installation process to improve the stability and aesthetics of the road surface. The curb caulking device is widely used in curb installation projects in urban roads, highways, squares, parking lots and other places.

[0003] When performing caulking operations on existing curbstones, the nozzle of the caulking gun is generally directly inserted into the gap of the curbstone, and then the staff continuously presses the caulking gun to discharge material to fill the gap. However, due to the different widths and lengths of the curbstone gaps, spraying material in one direction can easily cause material accumulation inside the gap, thereby affecting the uniformity of the caulking device spraying. If the operator manually moves the device left and right, it will consume a large manpower cost, thereby reducing the overall working efficiency of the device. Therefore, an adjustable curbstone caulking device is proposed to solve the problems raised in the background technology. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, the utility model provides an adjustable caulking device for curbstones, including a storage barrel 1, a rotating drum 2 movably connected inside the storage barrel 1, a guide groove 3 is provided on the surface of the rotating drum 2 in an annular shape at 180 degrees, a piston rod 4 is movably connected inside the storage barrel 1, the top of the piston rod 4 is fixedly connected to an outer cylinder 5, a first round block 6 is provided on the inner wall of the outer cylinder 5 in an annular shape at 180 degrees, a corrugated hose 7 is fixedly connected to the bottom of the storage barrel 1, a discharge pipe 8 is fixedly connected to the bottom of the corrugated hose 7, a square plate 9 is fixedly connected to the outer surface of the discharge pipe 8, a second round block 10 is fixedly connected to the two ends of the top of the square plate 9, and a triangular special-shaped cam 11 is fixedly connected to the bottom of the rotating drum 2.

[0022] The above-mentioned solution is adopted: the first round block 6 is movably connected to the inside of the guide groove 3, so that when the first round block 6 moves downward along the trajectory of the straight slot 13, it can drive the rotating drum 2 and the triangular special-shaped cam 11 at its bottom to rotate, and the longer diameter end of the triangular special-shaped cam 11 abuts against the second round block 10, so that during the rotation process, the longer diameter end of the triangular special-shaped cam 11 continuously abuts against the two second round blocks 10 respectively, thereby driving the square plate 9 and the discharge pipe 8 fixed thereon to move back and forth, thereby adjusting the injection position of the discharge pipe 8, which helps to evenly distribute the sealing material.

[0023] like Figures 1 to 3 As shown, the outer walls of the storage barrel 1 and the guide groove 3 are both provided with handles. The guide groove 3 consists of an oblique groove and a vertical groove. The first round block 6 is movably clamped inside the oblique groove of the guide groove 3 in the initial state. When the outer cylinder 5 moves downward, it drives the first round block 6 to slide along the trajectory of the guide groove 3 and rotates the rotating cylinder 2. The corrugated hose 7 is located in the middle of the triangular shaped cam 11. The outer wall of the storage barrel 1 is provided with a straight slot 13 that matches the first round block 6. The straight slot 13 is used to circumferentially limit the first round block 6.

[0024] The above scheme is adopted: the guide groove 3 includes a vertical groove, which is used to facilitate the removal of the first round block 6 from the inside of the guide groove 3, so that the outer cylinder 5 can drive the piston rod 4 to disengage from the inside of the storage barrel 1 after moving upward, thereby facilitating the delivery of materials into the interior of the storage barrel 1. A handle is provided on the outer wall of the storage barrel 1, which facilitates the operator to move and extract the storage barrel 1, thereby improving the overall convenience and practicality of the device.

[0025] like Figures 3 to 5 As shown, the piston rod 4 fits against the inner wall of the storage barrel 1, the discharge pipe 8 is conical in shape, and the discharge pipe 8 is connected to the storage barrel 1 through a corrugated hose 7. The top of the second round block 10 is provided with a protrusion that moves inside the storage barrel 1, and the inner wall of the storage barrel 1 is provided with a slide groove 12 for circumferentially limiting the protrusion. The triangular shaped cam 11 is located outside the storage barrel 1, and the end of the triangular shaped cam 11 with a longer diameter abuts against the second round block 10 away from the end of the discharge pipe 8. When the triangular shaped cam 11 rotates, it pushes the two second round blocks 10 to move.

[0026] The above solution is adopted: the discharge pipe 8 is conical in shape, so that the discharge pipe 8 can be easily inserted into the gap between the two curbs. At the same time, the conical discharge port can also help to concentrate the materials, thereby reducing material waste and unnecessary diffusion.

[0027] The working principle and use process of the present invention are as follows: the operator pulls up the handle at the top of the outer cylinder 5, thereby driving the piston rod 4 and the first round block 6 to move upward through the outer cylinder 5. When the first round block 6 slides to the inside of the vertical groove at the top of the guide groove 3, the first round block 6 continues to slide along the track of the vertical groove, thereby disengaging from the clamping connection with the rotating cylinder 2. At the same time, it also drives the piston rod 4 to disengage from the interior of the storage barrel 1, thereby facilitating the addition of caulking material into the interior of the storage barrel 1.

[0028] Subsequently, the operator aligns the bottom end of the discharge pipe 8 with the area to be caulked. At the same time, the bottom of the storage barrel 1 abuts against the surfaces of the two curbstones. At this time, the piston rod 4 is inserted into the interior of the storage barrel 1, so that the first round block 6 is re-engaged in the interior of the vertical groove of the guide groove 3. Then, by pressing the outer cylinder 5, the piston rod 4 is driven to squeeze the caulking material inside the storage barrel 1, so that the material flows into the gap through the corrugated hose 7 and the discharge pipe 8 under the action of pressure.

[0029] When the first round block 6 slides into the inside of the inclined groove of the guide groove 3, the outer cylinder 5 drives the first round block 6 to continue to move downward, so that the rotating cylinder 2 drives the triangular special-shaped cam 11 at its bottom to rotate, and then the longer diameter corner of the triangular special-shaped cam 11 abuts against one of the second round blocks 10, and drives the square plate 9 to move by squeezing one second round block 10. When the longer diameter corner of the triangular special-shaped cam 11 abuts against the other second round block 10, the triangular special-shaped cam 11 squeezes the other second round block 10 to drive the square plate 9 to move in the opposite direction, and then drives the discharge pipe 8 to move back and forth through the square plate 9, thereby facilitating the adjustment of the injection position of the discharge pipe 8, thereby improving the uniformity of filling the caulking material.
