Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a device for marking lines on foundation construction for rural construction. Background Technology

[0002] Before construction begins on the foundation, workers need to draw lines on the leveled ground. This line drawing provides an accurate reference for subsequent construction, ensuring the building's position, dimensions, and other requirements are met. When drawing lines, it's important to avoid drawing them on debris (such as leaves), as this will affect the adhesion of the lines, causing them to peel, curl, or fall off, resulting in poor line quality.

[0003] For example, Chinese Patent Application No. 202510794291.4 discloses a marking device for foundation construction, including a base plate and multiple casters on the lower end face of the base plate. A material box is provided on the upper end face of the base plate, with an upward-opening cavity for holding paint inside. A marking head penetrating the base plate is provided on the lower end face of the material box, and a detachable cover for closing the cavity is also provided on the upper end face of the material box. A first cleaning component is provided on the base plate; a second cleaning component is also provided on the lower end face of the base plate; a turning component and a stirring component are also provided inside the cavity. Through this structure, when the first cleaning component operates, it also drives the second cleaning component to clean debris below the base plate to both sides of the marking head, thereby preventing the marking head from drawing paint on debris, which would result in poor marking effect on the foundation.

[0004] In practical use, the above-mentioned solution presents challenges due to the difficulty in positioning the vehicle, leading to deviations and resulting in uneven lines. Furthermore, it may also cause issues with non-standard line markings during foundation construction.

[0005] Therefore, it is necessary to invent a construction line marking device for rural construction foundations to solve the above problems. Utility Model Content

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-5 As shown, the rural construction foundation marking device provided by this utility model includes a vehicle body 1, a bucket rack 2 fixedly installed on the top of the vehicle body 1, a material bucket 3 placed inside the bucket rack 2, the material bucket 3 being filled with paint, and the material bucket 3 being placed at an angle. A sealing cover plate 4 is fastened to the top of the material bucket 3, and an output pipe 5 is provided at the bottom of the material bucket 3. A cleaning component, a flattening component, a spraying component, and a positioning component are provided on one side of the vehicle body 1, and the cleaning component, flattening component, spraying component, and positioning component are arranged sequentially from the front end to the rear end of the vehicle body 1; the cleaning component, flattening component, spraying component, and positioning component sequentially achieve the purposes of cleaning impurities, leveling the ground, spraying and marking lines, and positioning the direction.

[0029] The cleaning component includes a bucket 6, with a spiral bar 7 rotatably connected to the inside of the bucket 6. As the bucket 6 moves forward, it removes large particles and protruding soil layers from the area to be painted in the foundation construction area and transfers them to the outside of the painting area via the spiral bar 7.

[0030] The flattening assembly includes a hanger 8 and a pressure roller 9. The pressure roller 9 is rotatably fitted inside the hanger 8, and its bottom end is lower than the lower surface of the hanger 8. A first drive motor 10 is fixedly connected to the bottom of the vehicle body 1. The first drive motor 10 is driven by the central shaft of the pressure roller 9 through a worm gear mechanism 11. The other end of the central shaft of the pressure roller 9 and the outer side of the spiral assembly 7 are both fixedly connected to pulleys 12. The two pulleys 12 are driven by a transmission belt 13. During operation, the bottom ends of the bucket 6 and the pressure roller 9 are in contact with the ground. The output shaft of the first drive motor 10 is driven by the worm gear mechanism 11 and connected to the pressure roller 9. With the cooperation of the pulleys 12 and the transmission belt 13, the spiral assembly 7 can rotate synchronously.

[0031] The spraying assembly includes at least two sets of spray guns 14, which are inserted into the adjusting frame 15 and limited by the first locking screw 16. A conveying pump 17 is installed on the top of the vehicle body 1. The input end of the conveying pump 17 is connected to the output pipe 5 through the feeding pipe. The output end of the conveying pump 17 is connected to the input end of multiple spray guns 14 through the diverting pipe 18. The output port of the spray gun 14 is higher than the bottom end of the pressure roller 9, that is, there is a gap between the output port of the spray gun 14 and the ground, and the distance between the output port of the spray gun 14 and the ground can be adjusted according to actual needs.

[0032] The positioning assembly includes an L-shaped guide rod 19 and a positioning wheel 20. The positioning wheel 20 is rotatably connected to the bottom end of the L-shaped guide rod 19, and an annular groove 21 is provided on the outer side of the positioning wheel 20. The positioning wheel 20 and the annular groove 21 are matched with the track placed at the location to be painted during foundation construction, that is, the positioning wheel 20 can move along the track to paint a straight line; or, a positioning mark is used to tighten at the location to be painted during foundation construction, and when the vehicle body 1 is pushed, the positioning mark always moves within the annular groove 21 of the positioning wheel 20.

[0033] Furthermore, in the above technical solution, the bucket 6 is detachably installed to the vehicle body 1 by bolts, and the top and one side of the bucket 6 are set as open, with the included angle of the inner cavity of the bucket 6 set as an arc structure tangent to the spiral feeder 7. This facilitates the scooping up of large particles of impurities and pushing them to the bottom of the spiral feeder 7 for discharge to one side.

[0034] Furthermore, in the above technical solution, the front wall of the bucket 6 is wedge-shaped, and a plurality of linearly arrayed screen holes 22 are provided on the bottom wall of the bucket 6. The cross-sectional shape of the screen holes 22 is strip-shaped, and the length direction of the screen holes 22 is parallel to the front-rear direction of the bucket 6. The screen holes 22 penetrate the bottom wall of the bucket 6, and the tail end of the screen holes 22 extends directly below the spiral rack 7. During the conveying of impurities and materials, small particles of soil and other materials that are scooped up can be screened through the screen holes 22.

[0035] Furthermore, in the above technical solution, the hanger 8 includes a mounting sleeve 801 and a U-shaped plate 802. The pressure roller 9 is located inside the U-shaped plate 802. A vertical rod 803 is fixedly connected to the center point of the top of the U-shaped plate 802, and the vertical rod 803 is detachably installed inside the mounting sleeve 801. The mounting sleeve 801 is detachably installed to the vehicle body 1 by bolts. The installation positions of the cleaning component and the flattening component can be adjusted according to the actual situation, and the corresponding transmission mechanism is adapted according to the actual installation situation.

[0036] Furthermore, in the above technical solution, the cross-sectional shape of the adjusting frame 15 is set to a U-shape, the spray gun 14 slides vertically inside the adjusting frame 15, the first locking screw 16 passes through the adjusting frame 15, and the end of the first locking screw 16 abuts against the outer wall of the spray gun 14. The height of the spray gun 14 can be adjusted. Since the paint sprayed by the spray gun 14 is radial, the higher the position of the spray gun 14, the larger the sprayed area, thereby adjusting the line width.

[0037] Furthermore, in the above technical solution, a cover 23 is provided at the bottom of the spray gun 14, outside the output port, and the cover 23 is detachably connected to the spray gun 14. The cover 23 can block the localized mist of paint and prevent interference from external factors such as wind, making the lines more standardized. To improve the straightness of the lines, a baffle can also be set in the line area, so that after spraying, the sprayed lines fall completely within the baffle's enclosure area.

[0038] Furthermore, in the above technical solution, the L-shaped guide rod 19 includes a main rod 191 and a rod sleeve 192. The rod sleeve 192 is movably fitted onto the bottom end of the main rod 191, and the rod sleeve 192 and the main rod 191 are locked together by a knob bolt 193. A rotating shaft is integrally provided at the bottom end of the rod sleeve 192, and a positioning wheel 20 is detachably installed on the outside of the rotating shaft. A protective sleeve made of rubber is fitted onto the outside of the positioning wheel 20.

[0039] Furthermore, in the above technical solution, the main rod 191 penetrates the side wall of the vehicle body 1 and slides with the through hole. A second locking screw 24 is movably installed on the top of the vehicle body 1 above the through hole, and the end of the second locking screw 24 abuts against the outer wall of the main rod 191. The positioning wheel 20 is adjustable in the width direction of the vehicle body 1 to facilitate positioning to the track or positioning mark, adapting to different marking requirements.

[0040] Furthermore, in the above technical solution, a second drive motor 25 is installed at the bottom axis of the material barrel 3, and the output shaft of the second drive motor 25 passes through the material barrel 3 and is connected to a stirring frame, which stirs the coating inside the material barrel 3. A ball valve 26 is installed on the output pipe 5.

[0041] Furthermore, in the above technical solution, a storage battery 27 is installed on the vehicle body 1, and the first drive motor 10, the second drive motor 25, and the delivery pump 17 are all electrically connected to the storage battery 27. The storage battery 27 can be used by connecting to an external power source or for charging, thus meeting the requirements of cordless operation.

[0042] The working process of this utility model is as follows: Move the equipment to a compacted foundation and assemble the cleaning, flattening, spraying, and positioning components with the vehicle body 1.

[0043] According to the architectural drawings, place the track in the construction area (where the lines to be painted) or set up ground nails on the outside of the construction area, and then use positioning marks to tighten them on the foundation construction at the area where the lines to be painted are to be painted.

[0044] The operator pushes the vehicle body 1 and aligns the positioning wheels 20 with the corresponding track or positioning marks. By pushing the vehicle body 1 along the track or positioning marks, the building foundation marking lines can be sprayed according to the actual drawings.

[0045] In operation, the output shaft of the first drive motor 10 is connected to the pressure roller 9 via a worm gear mechanism 11, and the spiral assembly 7 rotates synchronously with the cooperation of the pulley 12 and the transmission belt 13. Large particles and protruding soil layers in the area to be painted are removed during foundation construction and transferred to the outside of the painting area via the spiral assembly 7. Subsequently, the pressure roller 9 flattens the area to be painted, ensuring a high degree of cleanliness on the foundation surface. This allows the paint to adhere more evenly and firmly to the foundation, facilitating high-quality subsequent painting of the marking lines.

[0046] With ball valve 26 in the open position, delivery pump 17 draws out the paint from the material tank 3 and pressurizes it to be delivered to spray gun 14 for spraying onto the cleaned and level road surface to draw markings. While the paint is being sprayed, the operator must keep the device moving at a constant speed and smoothly along the predetermined route.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
