Abstract
Description
Technical Field
[0001] This utility model relates to a lime line-laying device, and more particularly to a lime line-laying device for construction projects. Background Technology
[0002] Lime marking in construction engineering is a traditional auxiliary method of construction surveying used to mark the outline, boundaries, or specific construction locations of buildings on the ground. This technique typically uses white lime powder to draw lines because white is highly visible and easily identifiable on most surfaces.
[0003] While existing lime line-laying devices have improved construction efficiency and line-laying accuracy to some extent, they still have some drawbacks and limitations. For example, lime tends to clump in humid environments, which may cause blockages at the discharge port and affect the construction progress.
[0004] Therefore, it is necessary to design a lime-line setting device for construction projects. Utility Model Content
[0005] In order to overcome the shortcomings of existing lime line-laying devices, which are prone to clumping in humid environments and may cause blockage of the discharge port, thus affecting the construction progress, the technical problem to be solved is to provide a lime line-laying device for construction projects.
[0006] The technical solution is as follows: A lime-laying device for construction projects, comprising a frame, a base, a first universal wheel, a second universal wheel, a first support frame, a hopper, a sealing plug, a motor, a large gear, a connecting rod, a stirring rod, and a small gear. The base is fixedly connected to the rear bottom of the frame. Symmetrically distributed first universal wheels are fixedly connected to both sides of the bottom of the base. Symmetrically distributed second universal wheels are fixedly connected to the front bottom of the frame. The first support frame is fixedly connected to the front end of the frame. A hopper is fixedly connected inside the first support frame. A sealing plug is slidably connected to the top of the hopper. A motor is fixedly connected to the top of the hopper. A large gear is fixedly connected to the top of the hopper. A connecting rod is connected to the output shaft of the motor. A stirring rod is rotatably connected to the other end of the connecting rod. A small gear is fixedly connected to the top of the stirring rod. The small gear meshes with the large gear. A pushing mechanism is also included, and the frame is equipped with the pushing mechanism.
[0007] Preferably, the pushing mechanism includes a first support rod, a handle, a first locking ball, and a first spring. The first support rod is fixedly connected to both the left and right sides of the top of the frame. The two first support rods have multiple symmetrically distributed first locking holes on both sides inside. The handle is slidably connected to both sides inside the two first support rods. The first locking ball is slidably connected to both sides inside the handle. The first locking ball is connected to the first support rod, and the two first locking balls are respectively engaged with the first locking holes.
[0008] Preferably, a material control mechanism is also included. The material control mechanism is provided on the hopper. The material control mechanism includes a second support frame, a first limiting plate, a pull ring, a stop block, and a second limiting plate. The second support frame is fixedly connected to the lower end of the hopper. An opening is opened on the second support frame. The first limiting plate is rotatably connected to the top of the second support frame. A pull ring is fixedly connected to the first limiting plate and slides in the opening. A stop block is slidably connected to the top of the first limiting plate. The second limiting plate is fixedly connected to the top of the second support frame, and the stop block is slidably connected to the second limiting plate.
[0009] Preferably, a support mechanism is also included. The base is provided with a support mechanism, which includes a slide rod, a second support rod, a second locking bead, and a second spring. The slide rod is fixedly connected to the bottom of the base. The second support rod is slidably connected to the outside of the slide rod. Multiple second locking holes are symmetrically distributed on both sides of the inside of the second support rod. The second locking bead is slidably connected to both sides of the inside of the slide rod. The second spring is connected between the second locking bead and the slide rod. The two second locking beads are respectively engaged with the second locking holes.
[0010] Preferably, it also includes a pre-aiming mechanism, which is provided on the frame. The pre-aiming mechanism includes a support block and a laser light. The support block is fixedly connected to the frame. A second omnidirectional wheel is fixedly connected to the bottom center of the support block. A laser light is fixedly connected to the front center of the support block.
[0011] Preferably, the hopper also includes scale lines, a transparent plate, and magnets. Scale lines are provided on the left side of the hopper, a transparent plate is fixedly connected to the hopper, and three evenly distributed magnets are fixedly connected above the opening of the support.
[0012] The beneficial effects of this utility model are as follows: 1. This utility model sets the output shaft of the motor to rotate, which drives the connecting rod to rotate. The rotation of the connecting rod drives the stirring rod to make a circular motion in the hopper. The rotation of the stirring rod drives the small gear to rotate on the large gear, thereby making the stirring rod itself rotate as well. This fully stirs the lime in the hopper, effectively solving the problem that the lime in the existing lime discharge device is prone to clumping in a humid environment, which may cause blockage of the discharge port and affect the construction progress.
[0013] 2. This utility model sets up a material control mechanism. When the pull ring is turned, the pull ring rotates and drives the first limiting plate to rotate. The rotation of the first limiting plate causes the stop block to slide within the first and second limiting plates. Since the pull ring is made of iron, the magnet will attract the pull ring, thereby fixing the position of the stop block. This allows the amount of lime falling out of the hopper to be controlled as needed, so that the lime is evenly spread on the ground.
[0014] 3. By setting up a pre-aiming mechanism, the laser light will illuminate the front horizontally in a straight line. Together with the second omnidirectional wheel at the bottom of the support block, it can help construction workers accurately align the line laying path.
[0015] 4. By setting scale lines and a transparent plate, this utility model allows construction personnel to observe the amount of lime remaining in the hopper at any time, thus avoiding material interruption and affecting the continuity of the laying line. Attached Figure Description

Detailed Implementation
[0028] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).
[0029] Example: A lime-based line-laying device for construction projects, such as... Figures 1-5 As shown, the device includes a frame 1, a base 3, first casters 4, second casters 5, a first support frame 6, a hopper 7, a sealing plug 8, a motor 9, a large gear 10, a connecting rod 11, a stirring rod 12, and a small gear 13. The base 3 is welded to the rear bottom of the frame 1. The first casters 4 are symmetrically distributed on both sides of the bottom of the base 3. The second casters 5 are symmetrically distributed on the front bottom of the frame 1. The first support frame 6 is welded to the front end of the frame 1. The hopper 7 is welded inside the first support frame 6. The sealing plug 8 is slidably connected to the top of the hopper 7. The motor 9 is fixedly connected to the top of the hopper 7. The large gear 10 is welded to the top of the hopper 7. The connecting rod 11 is connected to the output shaft of the motor 9. The stirring rod 12 is rotatably connected to the other end of the connecting rod 11. The small gear 13 is welded to the top of the stirring rod 12. The small gear 13 meshes with the large gear 10 to fully stir the lime in the hopper 7. The device also includes a pushing mechanism, which is provided on the frame 1.
[0030] like Figure 1 , Figure 8 and Figure 9As shown, the pushing mechanism includes a first support rod 2, a handle 202, a first locking bead 203, and a first spring 204. The top left and right sides of the frame 1 are welded with first support rods 2. Both sides of the two first support rods 2 have multiple symmetrically distributed first locking holes 201. The handles 202 are slidably connected to the inside of the two first support rods 2. The first locking beads 203 are slidably connected to the inside of the handles 202. The first springs 204 are connected between the first locking beads 203 and the first support rods 2. The two first locking beads 203 are respectively engaged with the first locking holes 201, so the construction personnel can adjust the height of the handles 202 according to their height requirements.
[0031] like Figure 3 , Figure 6 and Figure 7 As shown, it also includes a material control mechanism. The hopper 7 is equipped with a material control mechanism, which includes a second support frame 14, a first limiting plate 15, a pull ring 16, a stop block 17, and a second limiting plate 18. The second support frame 14 is welded to the lower end of the hopper 7. An opening 1401 is opened on the second support frame 14. The first limiting plate 15 is rotatably connected to the top of the second support frame 14. A pull ring 16 is welded to the first limiting plate 15. The pull ring 16 is made of iron and slides within the opening 1401. The stop block 17 is slidably connected to the top of the first limiting plate 15. The second limiting plate 18 is welded to the top of the second support frame 14. The stop block 17 and the second limiting plate 18 are slidably connected. This allows the amount of lime falling out of the hopper 7 to be controlled as needed, so that the lime is evenly spread on the ground.
[0032] like Figures 10-11 As shown, it also includes a support mechanism. The base 3 is equipped with a support mechanism, which includes a slide rod 19, a second support rod 20, a second locking bead 22, and a second spring 23. The slide rod 19 is welded to the bottom of the base 3. The second support rod 20 is slidably connected to the outside of the slide rod 19. Multiple second locking holes 21 are symmetrically distributed on both sides of the inside of the second support rod 20. The second locking bead 22 is slidably connected to both sides of the inside of the slide rod 19. The second spring 23 is connected between the second locking bead 22 and the slide rod 19. The two second locking beads 22 are respectively engaged with the second locking holes 21, so that after the wire is laid out, the device can be fixedly supported on the horizontal ground.
[0033] like Figure 2 As shown, it also includes a pre-aiming mechanism. The pre-aiming mechanism is provided on the frame 1. The pre-aiming mechanism includes a support block 24 and a laser light 25. The support block 24 is welded on the frame 1. A second universal wheel 5 is welded to the bottom center of the support block 24. A laser light 25 is fixedly connected to the front center of the support block 24. The laser light 25 will illuminate the front horizontally in a straight line. Together with the second universal wheel 5 at the bottom of the support block 24, it can help the construction personnel accurately align the line laying path.
[0034] like Figure 3 , Figure 6 and Figure 7 As shown, it also includes a scale line 27, a transparent plate 26, and magnets 28. The scale line 27 is provided on the left side of the hopper 7, and the transparent plate 26 is fixedly connected to the hopper 7. The scale line 27 on the left side of the hopper 7, together with the transparent plate 26, allows the construction personnel to observe the amount of lime remaining in the hopper 7 at any time, so as to avoid interruption of material and affect the continuity of the line laying. Three magnets 28 are fixedly connected above the opening 1401 of the support member. Since the pull ring 16 is made of iron, the magnets 28 will attract the pull ring 16, thereby fixing the position of the stop block 17.
[0035] When using lime line for laying, first remove the sealing plug 8 and open the hopper 7. Pour lime into the hopper 7, then replace the sealing plug 8 and close the hopper 7. Next, the worker adjusts the height of the handle 202 according to their height. Holding the handle 202, slide it up and down within the first support rod 2 at the appropriate height. The first locking ball 203, compressed by the first support rod 2, slides into the handle 202 and disengages from the first locking hole 201. The first spring 204 is compressed. When the appropriate height is reached, the first locking ball 203 aligns with the first locking holes 201 on the left and right sides respectively. The first spring 204 returns to its original state, allowing the first locking ball 203 to... The handle 202 slides out and engages with the first locking hole 201, thus fixing the handle 202 inside the first support rod 2. Then, by pulling the pull ring 16 to the left, the pull ring 16 rotates, causing the first limiting plate 15 to rotate. The rotation of the first limiting plate 15 causes the stop block 17 to slide within the first limiting plate 15 and the second limiting plate 18. Since the pull ring 16 is made of iron, the magnet 28 will attract the pull ring 16, thereby fixing the position of the stop block 17. This allows control of the amount of lime falling from the hopper 7, ensuring the lime is evenly spread on the ground. The motor 9 is then started, and the construction worker holds the handle 202 and pushes the entire device along the required line. As the path advances, the output shaft of motor 9 rotates, driving connecting rod 11 to rotate. Connecting rod 11 then causes stirring rod 12 to move in a circular motion within hopper 7. The rotation of stirring rod 12 drives small gear 13 to rotate on large gear 10, thus causing stirring rod 12 itself to rotate as well. This thoroughly mixes the lime in hopper 7. During this forward movement, laser light 25 illuminates the path horizontally. Combined with the second universal wheel 5 at the bottom of support block 24, this helps construction workers accurately align the layout path. The scale line 27 on the left side of hopper 7, along with the transparent plate 26, allows construction workers to observe the remaining lime in hopper 7 at any time, preventing material shortages from affecting the layout. To ensure continuity, after the line is laid out, hold the second support rod 20 by hand and let it slide downward outside the slide rod 19. The second locking bead 22 is squeezed by the second support rod 20 and slides into the slide rod 19, disengaging from the second locking hole 21. The second spring 23 is compressed, so that after the bottom of the second support rod 20 contacts the ground, the second locking bead 22 aligns with the second locking holes 21 on both sides. The second spring 23 returns to its original state, allowing the second locking bead 22 to slide out from the slide rod 19 and engage with the second locking hole 21, thereby fixing the slide rod 19 inside the second support rod 20, so that the device can be fixedly supported on the horizontal ground, thus completing the line laying work of lime.

Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
