Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and more specifically, it relates to a ground marking device for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at designated locations. During construction, lime needs to be sprinkled on the ground to mark lines for subsequent work.

[0003] Currently, most line marking is done manually by spreading lime, which is inefficient and results in uneven powder application, leading to unsatisfactory marking effects and wasted resources. Furthermore, due to the presence of pebbles and clods on the ground, direct marking results in poor floor marking quality, further affecting efficiency. Therefore, this paper studies and improves the existing structure and its shortcomings to provide a floor marking device for construction, aiming to achieve greater practical value.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a ground marking device for building construction, including a hopper 1. A front rod 2 is fixedly installed on one bottom side of the hopper 1, and a caster wheel 3 is installed on the bottom end of the front rod 2. Two sets of rear rods 4 are fixedly installed on the other bottom side of the hopper 1. A rotating shaft 5 is installed between the two sets of rear rods 4, and both ends of the rotating shaft 5 extend to the outside of the two sets of rear rods 4 and are equipped with movable wheels 6. The bottom end of the hopper 1 is connected to a discharge pipe 7, and the interior of the discharge pipe 7 can rotate. A material control shaft 8 is connected, and multiple sets of material control blades 9 are connected to the outer side of the material control shaft 8; the bottom end of the discharge pipe 7 is connected to a conveying pipe 10, and a conveying auger 11 is horizontally connected inside the conveying pipe 10; a base plate 12 is fixedly installed on one side of the front rod 2, and two sets of telescopic rods 13 are vertically installed at the bottom end of the base plate 12. The bottom ends of the two sets of telescopic rods 13 are connected to a fixing block, and a push plate 14 is installed on one side of the two sets of fixing blocks, and the push plate 14 is arranged in a V shape.

[0026] The rotating shaft 5 has a worm gear 15 installed at its center. The top of the worm gear 15 is engaged with a worm wheel 16. The center of the worm wheel 16 is connected to a fixed shaft 17. One end of the fixed shaft 17 extends into the material conveying pipe 10 and is coaxially connected with the conveying auger 11. This facilitates a uniform line drawing effect, ensures the uniformity of ash output from the line feeding device, and makes the line drawing efficiency higher.

[0027] Among them, the fixed shaft 17 is equipped with a gear 18 near the outside of the conveying pipe 10. The top of the gear 18 is engaged with a gear 19. One end of the material control shaft 8 passes through the discharge pipe 7 and is fixedly connected to the gear 19. This facilitates the material control of lime, prevents lime from clumping in the hopper 1, and effectively controls the amount of lime discharged, thus making it easier to mark lines.

[0028] The worm gear 16 and worm 15 are equipped with a protective cover 20 on their outer sides, and both sides of the protective cover 20 are connected to the rear rod 4; the gear 18 and gear 29 are equipped with a protective cover 21 on their outer sides, and the bottom end of the protective cover 21 is connected to the conveying pipe 10, so as to prevent the human body from contacting the internal parts of the protective cover 20 and the protective cover 21, and at the same time, to avoid damage to the parts by external environmental factors.

[0029] The material conveying pipe 10 is provided with an elbow at one end, with the opening of the elbow facing downwards, which facilitates the falling of lime and improves the practicality of the marking device.

[0030] Both sets of telescopic rods 13 are fitted with springs 22 on their outer sides, and the two ends of the springs 22 are respectively set to abut against the top of the fixed block and the bottom of the base plate 12, so that the bottom of the push plate 14 can contact the ground, so that stones or protruding soil at the front end of the universal wheel 3 can be cleared, improving the marking effect. At the same time, it can provide cushioning and increase the elastic restoring force of the telescopic rod 13, ensuring the normal use of the telescopic rod 13.

[0031] The hopper 1 is fixedly equipped with a handle 23 on one side, and the outer side of the handle 23 is fitted with an anti-slip sleeve to increase the friction between the hand and the handle 23, so that the operator can grip it more firmly and at the same time provide a comfortable touch and reduce hand fatigue.

[0032] The working principle of this embodiment:

[0033] When using the marking device, first move the hopper 1 to the area where the marking is needed, then pour lime into the hopper 1. Next, grasp the handle 23 and push the hopper 1 to mark the line. As the two sets of moving wheels 6 rotate, they drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the worm gear 15 and the worm wheel 16 meshing with the worm gear 15 to rotate, thereby causing the fixed shaft 17 connected to the worm wheel 16 to drive the conveying auger 11 and gear 18 inside the conveying pipe 10 to rotate. When gear 18 rotates, it drives gear 2 19 to rotate, thereby causing the conveying auger 11 and gear 18 inside the conveying pipe 10 to rotate. The control shaft 8 and the control blade 9, which are coaxially connected to the gear 2 19, rotate to control the lime and prevent it from clumping in the hopper 1, thus affecting the subsequent marking operation. When the conveying auger 11 and the control blade 9 rotate, the lime falls evenly from the ash outlet of the conveying pipe 10 to the ground, thus completing the marking. When the hopper 1 moves, the push plate 14 on one side of its front rod 2 can push away the stones or clods of soil on the ground, which facilitates the movement of the casters 3 and the moving wheels 6 and makes the marking effect better.

[0034] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
