AI Technical Summary
Traditional line marking devices suffer from uneven slurry spraying when the moving speed changes, leading to slurry waste and unclear lines.
The feeding structure is driven by a drive component to draw the slurry in the storage tank into the spraying structure. The slurry is then evenly distributed into the pressure equalization chamber through the distribution box and distribution pipe, and sprayed out through the spraying holes to ensure that the amount of slurry sprayed out matches the moving speed of the device.
This achieves uniformity and continuity of grout spraying, improves the quality of line marking, saves grout usage, and reduces construction costs.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a building construction marking device. Background Technology
[0002] Building construction marking equipment refers to tools or equipment used for marking and marking lines during the construction of buildings. They can help construction workers to accurately mark lines inside and outside buildings to ensure the precision and accuracy of construction work. They are mainly used to mark the boundaries of building structures, the scope of construction areas, and the location of equipment installations.
[0003] However, traditional marking devices cannot precisely control the amount of marking slurry sprayed according to construction needs. When the device's moving speed changes, uneven slurry spraying can easily occur. Excessive spraying will waste slurry and increase construction costs; insufficient spraying may result in unclear or incomplete markings, affecting construction progress and quality. For example, Chinese Patent Publication No. CN 222350286 U provides a marking device for building construction. Through the cooperation between the moving wheel, the first connecting rod, the second connecting rod, and the limiting sleeve, the first connecting rod moves back and forth with the rotation of the moving wheel, thereby driving the second slurry plate to move back and forth at the bottom of the first slurry plate. When the through hole between the second slurry plate and the first slurry plate is open, the material is sprayed; when closed, the opposite is true. In summary, the faster the driving speed, the faster the moving wheel rotates and the faster the material is sprayed, thus realizing the marking work during building construction.
[0004] However, since the slurry falls by gravity, and the slurry has a certain viscosity, and the through holes between the second and first perforated plates are staggered, the slurry will fall intermittently, which will still result in uneven marking. Therefore, in order to make the slurry sprayed evenly on the marking position during marking, a building construction marking device is proposed. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a construction marking device that avoids uneven slurry spraying caused by changes in the device's moving speed, effectively improving marking quality and saving slurry usage and construction costs.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a building construction marking device, comprising a base plate, a feeding structure, a spraying structure, a driving component, and a storage box;
[0007] The spraying structure is fixedly installed at the front end of the base plate. It includes a discharge plate and a distribution box. Two pressure equalization chambers are symmetrically opened in the discharge plate. A distribution pipe is provided between the pressure equalization chamber and the distribution box.
[0008] The drive assembly includes a rotating wheel and a rotating shaft that rotate on the base plate. The rotating wheel drives the rotating shaft to rotate via a belt drive.
[0009] The storage bin is fixedly installed on the top of the base plate and is used to store the marking slurry;
[0010] The feeding structure is fixedly installed on one side of the base plate. It includes a pump housing, a driven gear, and a driving gear. The driven gear and the driving gear rotate inside the pump housing and mesh with each other to generate suction force to send the slurry in the storage tank into the spraying structure.
[0011] As a further description of the above technical solution:
[0012] The drive assembly further includes: a rotating shaft, which is rotatably connected to the base plate; two rotating wheels are provided, and the central shaft of one of the rotating wheels is fixedly connected to the rotating shaft; a pulley is fixedly connected to the rotating shaft.
[0013] A second pulley is fixedly connected to the rotating shaft, and a transmission belt is installed on both the first pulley and the second pulley.
[0014] As a further description of the above technical solution:
[0015] A drive shaft is fixedly connected to the drive gear, and the drive shaft is fixedly connected to the rotating shaft through a coupling.
[0016] As a further description of the above technical solution:
[0017] The pump casing is provided with a feed chamber and a discharge chamber on both sides. The feed chamber is connected to the storage tank through a pipe, and the discharge chamber is connected to the pressure equalization chamber through a pipe.
[0018] As a further description of the above technical solution:
[0019] The bottom of the discharge plate is provided with a spray hole, which extends into the pressure equalization chamber.
[0020] As a further description of the above technical solution:
[0021] The bottom of the base plate is also equipped with a moving component, which includes two sets of omnidirectional wheels.
[0022] As a further description of the above technical solution:
[0023] A push handle is installed on the top of the base plate, and the push handle is located at the end away from the spray structure.
[0024] This utility model has the following beneficial effects:
[0025] 1. In this utility model, the feeding structure is driven by the drive component to draw the slurry in the storage box into the spraying structure, thereby making the spraying speed of the device match the movement of the device. The movement speed of the device is positively correlated with the amount of slurry sprayed. When the movement is slower, the amount of slurry sprayed decreases accordingly; when the movement is faster, the amount of sprayed increases. This effectively avoids the problem of uneven slurry spraying caused by changes in the movement speed of the device, which not only ensures the quality of the marking, but also saves the amount of slurry used and reduces the construction cost.
[0026] 2. In this utility model, the feeding structure is driven by the movement of the device, and an active extraction method is used to draw the slurry in the storage tank into the spraying structure, which can ensure the uniformity and continuity of the slurry sprayed by the spraying structure.
[0027] 3. The distribution box evenly distributes the slurry into the two sets of equalizing chambers through the distribution pipe. Finally, the slurry is sprayed out from multiple spray holes at the bottom of the discharge plate. In this process, the pressure generated by the pressurization of the feeding structure can be effectively dispersed, ensuring that the slurry can be sprayed out evenly from multiple spray holes, avoiding the uneven spraying caused by pressure concentration, making the marking clearer and more complete, and improving the accuracy of construction.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0037] Example 1:
[0038] Reference Figures 1-6 The present invention provides an embodiment of a building construction marking device, characterized in that it includes a base plate 1, a feeding structure 2, a spraying structure 3, a driving component 4, and a storage box 6.
[0039] The spraying structure 3 is fixedly installed at the front end of the base plate 1, and includes a discharge plate 31 and a diversion box 33;
[0040] The drive assembly 4 includes a rotating wheel 41 and a rotating shaft 44 that rotate on the base plate 1. The rotating wheel 41 drives the rotating shaft 44 to rotate via a belt drive.
[0041] The storage bin 6 is fixedly installed on the top of the base plate 1 and is used to store the marking slurry;
[0042] The feeding structure 2 is fixedly installed on one side of the base plate 1. It includes a pump housing 21, a driven gear 22 and a driving gear 23. The driven gear 22 and the driving gear 23 both rotate inside the pump housing 21 and mesh with each other to generate suction force to send the slurry in the storage tank 6 into the spraying structure 3.
[0043] The drive assembly 4 also includes: a rotating shaft 42, which is rotatably connected to the base plate 1; two rotating wheels 41 are provided, and the central shaft of one of the rotating wheels 41 is fixedly connected to the rotating shaft 42; and a pulley 43 is fixedly connected to the rotating shaft 42.
[0044] A second pulley 45 is fixedly connected to the rotating shaft 44, and a transmission belt 46 is installed on the first pulley 43 and the second pulley 45.
[0045] A drive shaft 24 is fixedly connected to the drive gear 23, and the drive shaft 24 is fixedly connected to the rotating shaft 44 through a coupling.
[0046] The pump casing 21 has an inlet chamber 25 and an outlet chamber 26 on its two sides respectively. The inlet chamber 25 is connected to the storage box 6 through a pipe, and the outlet chamber 26 is connected to the pressure equalization chamber 32 through a pipe.
[0047] Working principle: When marking lines on building construction, the marking slurry is first placed in the storage box 6. Then, the staff pushes the device to move. When the device moves, the rotating wheel 41 rotates with the device. The rotating wheel 41 drives the rotating shaft 42 to rotate. Through the transmission action of pulley 1 43, pulley 2 45 and transmission belt 46, the rotating shaft 44 is driven to rotate, which in turn drives the drive component 4 to rotate. This causes the meshing driven gear 22 and drive gear 23 to rotate, drawing the liquid in the feed chamber 25 into the discharge chamber 26, thereby drawing the slurry in the storage box 6 into the spraying structure 3.
[0048] At this time, the amount of slurry sprayed by the spraying structure 3 can change with the speed of the device movement. When the device moves slowly, the amount of slurry sprayed can be reduced; when the device moves fast, the amount of slurry sprayed can be increased. This can avoid uneven slurry spraying caused by changes in the device movement speed, and can also save the amount of slurry used.
[0049] Example 2:
[0050] Reference Figure 5 Based on Example 1, since the slurry enters 3 under pressure through 2, in order to further increase the uniformity of slurry spraying;
[0051] Two equalizing chambers 32 are symmetrically arranged inside the discharge plate 31. A diversion pipe 34 is provided between the equalizing chamber 32 and the diversion box 33. A spray hole 35 is provided at the bottom of the discharge plate 31, and the spray hole 35 penetrates into the interior of the equalizing chamber 32.
[0052] The bottom of the base plate 1 is also equipped with a moving component 5, which includes two sets of casters 51.
[0053] A push handle 7 is installed on the top of the base plate 1, and the push handle 7 is located at the end away from the spray structure 3;
[0054] The staff can move the device by pushing it with the handle 7, while the casters 51 allow the device to be turned easily.
[0055] Working principle: After the feeding structure 2 draws the pressurized slurry into the distribution box 33, the distribution box 33 then sends the slurry into the two sets of equalizing chambers 32 through the distribution pipe 34. Finally, the slurry is sprayed out from the spray hole 35 to the marking position, completing the marking work during building construction. At this time, the pressure generated by the pressurization of the feeding structure 2 is distributed to the two sets of equalizing chambers 32 by the distribution box 33, so that the pressure can be dispersed and the slurry can be sprayed out more evenly from multiple sets of spray holes 35, avoiding the phenomenon of uneven slurry spraying caused by pressure concentration.
[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
