Description

Technical Field

[0001] This utility model relates to the field of road construction equipment technology, and in particular to a handheld road marking device. Background Technology

[0002] Road marking is an important task in the later stages of road construction. Existing road marking machines mainly consist of a vehicle body, wheels, and marking brushes installed on the vehicle body. When workers push the vehicle body, the marking brushes will mark lines along the vehicle's path. During the construction of road surfaces and plazas, it is often necessary to mark some marking lines. Usually, brushes dipped in ink, stone pencils, pencils, etc. are used to draw lines. Road surfaces use lines, arrows, words, vertical markings, raised pavement markers, and delineators to convey traffic information such as guidance, restrictions, and warnings to traffic participants.

[0003] The patent specification with announcement number CN202420993299.4 discloses a handheld road marking device, which "includes a feeding funnel for loading paint, a switching ring for switching feeding nozzles, and a marking housing for fixing the switching ring and the feeding funnel. This utility model, through the above structure, by setting a rotatable switching ring in the marking housing and setting several feeding nozzles of different thicknesses on the switching ring, enables the switching of different thickness feeding nozzles by rotating the switching ring. This achieves the effect of adjusting the thickness of the lines when the paint leaking from the feeding funnel is used for marking, solving the problem in the prior art that construction workers cannot adjust the thickness of the lines in real time when marking the ground, resulting in a decrease in work efficiency, and improving the work efficiency of construction workers when marking the ground."

[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned road marking device: Traditional handheld road marking devices adjust the thickness of the ink through multiple nozzles, but during the process of switching between nozzles to change the ink thickness, some ink is easily contaminated on the surface of the marking device, which leads to uneven ink contamination at the nozzles and thus affects the marking effect of the marking device. In view of this, a handheld road marking device is provided to overcome the above defects. Utility Model Content

At the same time, the two return springs contract, which can increase the diameter of the inside of the spray tube, thereby quickly adjusting the ink output of the scribing device.

[0008] As a further description of the above technical solution: the uniform component includes a first motor, a stirring shaft and a plurality of stirring rods. The first motor is fixedly installed at the middle of the top of the stirring chamber. The drive shaft of the first motor is fixedly connected to the stirring shaft, and a plurality of stirring rods are fixedly provided on the surface of the stirring shaft.

[0023] Reference Figure 1-4 This utility model provides a handheld road marking device, which includes a base 1, a mixing chamber 2 fixedly provided on one side of the top of the base 1, and pads 3 fixedly provided on the top of both sides of the mixing chamber 2. An ink pump 4 and an air pump 5 are fixedly provided on the top of the two pads 3 respectively. The ink pump 4 is connected to the interior of the mixing chamber 2. The ink pump 4 is fixedly connected to the spray pipe 6 through the ink outlet pipe. The bottom end of the spray pipe 6 is threadedly connected to the feed cylinder 7. An adjustment component 8 is provided between the spray pipe 6 and the feed cylinder 7. A homogenizing component 9 is provided inside the mixing chamber 2.

[0024] As a further implementation of the above technical solution: the adjustment component 8 includes two first slide grooves 81, two return springs 82, two material blocking rings 83, two push rods 84 and two protrusions 85. The two first slide grooves 81 are respectively opened on the inner walls of both sides of the spray pipe 6. A return spring 82 is fixedly provided on one side of the inner wall of each of the two first slide grooves 81. A material blocking ring 83 is fixedly provided at one end of each of the two return springs 82. The two material blocking rings 83 are slidably connected to the two first slide grooves 81 respectively. The two push rods 84 are respectively fixedly provided on the inner walls of the top ends of both sides of the spray pipe 6. A protrusion 85 is fixedly provided at the top end of each of the two push rods 84.

[0025] A second motor 10 is fixedly installed on one side of the spray tube 6. The drive shaft of the second motor 10 is fixedly connected to a first gear 11. A second gear 12 is fixedly installed on the surface of the feed cylinder 7. The second gear 12 meshes with the first gear 11. The second motor 10 starts and drives the first gear 11 to rotate. Since the second gear 12 meshes with the first gear 11, the second gear 12 and the feed cylinder 7 rotate. The feed cylinder 7 moves upward while spiraling inside the spray tube 6. Then, through the two push rods 84, the two protrusions 85 respectively squeeze the two blocking rings 83. At this time, the two return springs 82 are compressed by force. After the two blocking rings 83 slide into the inner wall of the two first sliding grooves 81, the ink flow gap of the spray tube 6 can be adjusted so as to adjust the ink volume according to different line drawing requirements.

[0026] As a further implementation of the above technical solution: the uniform component 9 includes a first motor 91, a stirring shaft 92 and a plurality of stirring rods 93. The first motor 91 is fixedly installed in the middle of the top of the stirring chamber 2. The transmission shaft of the first motor 91 is fixedly connected to the stirring shaft 92. A plurality of stirring rods 93 are fixedly provided on the surface of the stirring shaft 92.

[0027] The inner walls of several stirring rods 93 are rotatably connected to several auxiliary shafts 13 via bearings, and fan-shaped plates 14 are fixed on both sides of the several auxiliary shafts 13.

[0028] An aeration pipe 15 is fixedly installed on the inner wall of the bottom of the mixing chamber 2. Several nozzles 16 are fixedly installed at the top of the aeration pipe 15. The nozzles 16 are arranged in a circumferential inclined manner. The air outlet of the air pump 5 is connected to the aeration pipe 15 through the air outlet pipe. The first motor 91 drives the mixing shaft 92 and several mixing rods 93 to rotate. During the rotation of the several mixing rods 93, the several auxiliary shafts 13 are affected by the inertia of the ink and drive several fan-shaped plates 14 to rotate, thereby performing secondary mixing of the ink. At the same time, the air pump 5 draws in external gas and injects it into the several circumferentially inclined nozzles 16 through the aeration pipe 15. During the mixing process, the ink is injected with air and generates a large number of bubbles. The bubbles are then rotated by the inclined angle of the several nozzles 16, thereby improving the uniformity of the ink.

[0029] As a further implementation of the above technical solution: rollers 17 are fixedly provided at the four corners of the bottom of the base 1, and pushers 18 are fixedly provided on the surface of the base 1.

[0030] As a further implementation of the above technical solution: the surface of the pusher 18 is provided with a switch panel 19, and the surface of the switch panel 19 is provided with an ink pump switch, an air pump switch, a first motor switch and a second motor switch. The ink pump 4, the air pump 5, the first motor 91 and the second motor 10 are electrically connected to the power supply through the ink pump switch, the air pump switch, the first motor switch and the second motor switch respectively.

[0031] Working Principle: When using this invention, firstly, the ink for marking lines is fed into the mixing chamber 2 through the feed pipe at the top of the mixing chamber 2. Then, the first motor switch and air pump switch on the switch panel 19 are turned on. After the first motor 91 starts, it drives the mixing shaft 92 and several mixing rods 93 to rotate. During the rotation of the mixing rods 93, several auxiliary shafts 13, influenced by the inertia of the ink, cause several fan-shaped plates 14 to rotate, thus performing secondary mixing of the ink. Simultaneously, the air pump 5 draws in external gas and injects it into several inclined nozzles 16 through the aeration pipe 15. During the mixing process, the ink is injected with air, generating a large number of bubbles. These bubbles then rotate due to the tilt angle of the nozzles 16, thereby improving the ink's agitation. The uniformity of the ink is further improved by several rollers 17 and pushers 18 pushing the marking device to move. When the bottom of the lower cylinder 7 is directly above the marking point, the second motor 10 is started to drive the first gear 11 to rotate. Since the second gear 12 is meshed with the first gear 11, the second gear 12 and the lower cylinder 7 rotate. The lower cylinder 7 moves upward while spiraling inside the spray tube 6. Then, the two push rods 84 cause the two protrusions 85 to squeeze the two blocking rings 83 respectively. At this time, the two return springs 82 are compressed by force. After the two blocking rings 83 slide into the inner wall of the two first grooves 81 respectively, the ink flow gap of the spray tube 6 can be adjusted so as to adjust the amount of ink according to different marking requirements.
