Description

Technical Field

[0001] This utility model relates to a road construction machine, and more specifically, to a line marking machine. Background Technology

[0002] A line marking machine is a type of road construction machinery widely used in roads, highways, parking lots, squares, and runways to mark various rules and restrictions such as constraints, guidance, and warnings on flat ground. Line marking machines have played a significant role in urban planning and highway construction due to their advantages of speed, efficiency, and accuracy.

[0003] Traditional line marking machines use a single-strand brushing design, but the actual road surface uses parallel double-line marking. Using a single-strand line marking machine to brush back and forth on the double straight lines is too inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a line marking machine that uses two parallel brushes, allowing workers to complete the marking of two straight lines in one pass, thus improving the efficiency of drawing double-line markings.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A marking machine includes a frame with wheels underneath and a handle. A first and second bracket with identical structures are sequentially inserted into one side of the frame. The inserted structure includes a hexagonal shaft and a hexagonal cylinder, with plugs for fixing inserted into the sides of the hexagonal cylinder and shaft. The first and second brackets are equipped with coating components. The frame has two material cylinders connected to independent pump bodies, which supply material to two coating components.

[0007] The frame is equipped with a battery, which supplies power to the pump body.

[0008] Preferably, the two material cylinders are arranged one above the other.

[0009] Preferably, the coating component includes two roller brushes in contact with the ground, a pump body connected to a hose facing the roller brushes, and a first bracket and a second bracket having a nozzle connected to the hose.

[0010] Preferably, the nozzle and hose are connected using a quick-connect coupling.

[0011] Preferably, the hexagonal shaft has multiple threaded holes arranged along the length of the hexagonal shaft, and the plug is connected to the threaded holes.

[0012] Preferably, the paint brush is rotatably connected to the bracket, and the bracket is provided with a torsion spring that drives the paint brush to rotate downward.

[0013] Preferably, the frame has an upper plate and a lower plate, with two material cylinders located on the upper plate and the lower plate respectively; both the upper plate and the lower plate have fixing holes, which are matched with a hexagonal shaft; the hexagonal shaft is inserted into the fixing hole and extends downwards out of the plate, and is fixed by the threaded hole below the plate, so that the blockage is located below the plate.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] When the two marking lines are different colors, the paint cannot be mixed. Therefore, two separate paint cylinders are used to supply paint to the two painting parts.

[0016] The brush assembly is connected by a plug-in fixing method, which can meet the user's requirements for drawing marking lines with single strands and double strands; and the brush assembly can be removed and placed on the frame after removal, reducing the area of ​​the bottom of the marking machine and making it easier for trucks to load and transport the marking machine.

[0017] The fit between the hexagonal shaft and the plug provides constraints on the insertion relationship in both the circumferential and shaft directions.

[0018] Using two paintbrushes, the painting of two straight marking lines can be completed in one pass when drawing double marking lines, thus improving the efficiency of drawing parallel double marking lines. Attached Figure Description

[0035] The present invention will be further described in detail below with reference to the accompanying drawings.

[0036] Example 1, a line marking machine, referring to Figure 1 It includes a frame 1, with four wheels 11 below the frame 1 and a handle 12. Employees can hold the handle 12 and apply force to move the frame 1.

[0037] A first bracket 21 and a second bracket 22 are sequentially inserted into one side of the frame 1;

[0038] The first support 21 and the second support 22 have the same structure;

[0039] The first bracket 21 is inserted into one side of the frame 1, and the second bracket 22 is inserted into one side of the first bracket 21, so that the first bracket 21 and the second bracket 22 are arranged in parallel.

[0040] Reference Figure 3 The second support 22 includes a shaft 202, on which two upright plates 203 are mounted. A coating component 5 is rotatably connected between the two upright plates 203. The coating component 5 includes two roller brushes 51, which are rotatably connected to the upright plates 203.

[0041] The two roller brushes 51 are set in abutting position, and the paint falls between the two roller brushes 51. The roller brushes 51 rotate on the ground at any time, applying the paint to the ground.

[0042] Reference Figure 3 A nozzle 201 is fixed on the shaft 202. The nozzle 201 is located above the roller brush 51 and points between the two roller brushes 51.

[0043] Reference Figure 2 The nozzle 201 is connected to a hose 63 via a clamp 205 at its upper end;

[0044] Reference Figures 2-3 The shaft 202 is also fixed with a guide frame 204, which has a through hole, through which the flexible hose 63 passes;

[0045] The guide frame 204 is located above the nozzle 201, and its function is to position the hose 63.

[0046] Two material cylinders 61 are installed on the frame 1, arranged vertically; the two material cylinders 61 can be removed and placed from the frame 1.

[0047] A vertical plate is fixed to the frame 1, and a pump body 62 is installed on the vertical plate; the pump body 62 delivers the paint in the barrel 61 to the corresponding painting part 5 through the hose 63.

[0048] Reference Figure 1 The front end of the frame 1 is equipped with a battery 64, which is a storage battery that supplies power to the pump body 62 and controls the switches of the two pump bodies 62 through a switch.

[0049] Reference Figure 1-3 In this design:

[0050] The lower material cylinder 61 is connected to the pump body 62, the hose 63 and the nozzle 201 of the first bracket 21;

[0051] The upper material cylinder 61 is connected to the pump body 62, the hose 63, and the nozzle 201 of the second bracket 22;

[0052] An independent material cylinder 61 supplies material to two brushes 5, enabling the two brushes 5 to coat the ground.

[0053] The parallel installation relationship of the first bracket 21 and the second bracket 22 is as follows.

[0054] Reference Figure 3 For the second bracket 22, a hexagonal tube 32 is provided at one end of its shaft 202, and a hexagonal shaft 31 is fixed at the other end of the shaft 202;

[0055] The hexagonal shaft 31 and the hexagonal tube 32 can be inserted in a matching size.

[0056] The hexagonal shaft 31 has a threaded hole 42, and the hexagonal tube 32 has an insertion hole. The plug 41 is inserted into the insertion hole and then threaded onto the threaded hole 42, thereby further fixing the hexagonal shaft 31 and the hexagonal tube 32.

[0057] The specific connection relationship is as follows:

[0058] A hexagonal tube 32 is installed on the frame 1. The hexagonal shaft 31 of the first bracket 21 is inserted into the hexagonal tube 32 of the frame 1 and then fixed by the plug 41.

[0059] The hexagonal shaft 31 on the second bracket 22 is inserted into the hexagonal tube 32 of the first bracket 21 and is also fixed by the plug 41;

[0060] This arrangement ensures that the first support 21 and the second support 22 are arranged in parallel on the same side of the frame 1, with the first support 21 and the second support 22 spaced apart.

[0061] Working principle:

[0062] The worker pushes the frame 1, and the first support 21 and the second support 22 apply two marking lines, which improves the painting efficiency;

[0063] The addition of brackets increases the bottom size of the marking machine, which is not conducive to loading and transporting the marking machine by the vehicle. The plug-in structure of this design overcomes this problem. This design adopts a detachable first bracket 21 and second bracket 22, which can be removed from one side of the frame 1 during transportation, so as to facilitate the loading of the marking machine onto the vehicle body.

[0064] Example 2, a marking machine, differs from Example 1 in that, see below. Figure 4 The hexagonal shaft 31 has multiple threaded holes 42, three in this embodiment. The threaded holes 42 are arranged along the length of the hexagonal shaft 31, and the plug 41 is connected to the threaded holes 42. There are various requirements for the spacing between the two marking lines. Users can adjust the connection relationship between the plug 41 and the threaded holes 42 to adjust the specific spacing between the two brackets.

[0065] The brush 5 is rotatably connected to the bracket, and the bracket is provided with a torsion spring 7 that drives the brush 5 to rotate downward.

[0066] One end of the torsion spring 7 is fixed to the vertical plate 203, and the other end of the torsion spring 7 is fixed to the shaft 202;

[0067] The two upright plates 203 are rotatably connected to the shaft 202, so the torsion spring 7 can exert a force on the upright plates 203 and the paint brush 5 to press against the ground, so that the paint brush 5 is stably attached to the ground and the paint and the ground are in fuller contact.

[0068] Example 3, a marking machine, differs from Example 1 or Example 2 in that, see below. Figure 5 The nozzle 201 and the hose 63 are connected by a quick connector 8. The advantage of the quick connector 8 is that it is easy to install and remove.

[0069] The quick connector 8 has two connectors: one is fixed to the hose 63, and the other is fixed to the nozzle 201. This allows for quick assembly and disassembly of the hose 63 and the nozzle 201.

[0070] Figure 1The frame has an upper plate and a lower plate, with two material cylinders 61 located on the upper and lower plates respectively. Both the upper and lower plates are provided with fixing holes 91, which cooperate with the hexagonal shaft 31 to house the two supports in the frame. The hexagonal shaft 31 can be inserted into the fixing hole 91 to position and install the two relatively stable supports on the frame.

[0071] The hexagonal shaft 31 extends downwards from the plate and is fixed to the plug 41 and the threaded hole 42 below the plate, so that the plug 41 is blocked below the plate, making the installation of the bracket on the frame 1 more stable.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
