Description

Technical Field

[0001] This utility model relates to an anti-sticking wheel device, or more precisely, an anti-sticking wheel device with an asphalt roller oil spraying device. Background Technology

[0002] Existing anti-sticking roller devices continuously spray anti-sticking grease onto the roller surface during use. This can easily lead to excessive grease on the roller surface and waste of anti-sticking grease. For example, prior art patent 1, publication number CN201686918U, discloses a Chinese utility model patent document for an automatic oil spraying device for asphalt rubber-tired rollers. As shown in Figure 9, the technical solution disclosed in this patent document continuously sprays oil onto the asphalt roller rollers. This can easily lead to excessive oil adhering to the surface of the asphalt roller rollers, resulting in waste. Summary of the Invention

[0003] The purpose of this invention is to provide an anti-sticking wheel device with an asphalt roller oil spraying device. It can use an electric push device to drive several first pistons to slide back and forth, thereby allowing several through holes to open and close repeatedly. This allows the nozzle to spray once and then stop, spraying repeatedly. After being evenly coated by a brush wheel and a replaceable plastic plate, it can reduce the amount of oil sprayed compared to the prior art and avoid excessive oil waste.

[0004] To achieve the above objectives, this utility model employs the following technical solution: An anti-sticking wheel device with an asphalt roller oil spraying device includes a roller vehicle. The asphalt roller oil spraying device is installed on the roller vehicle body. The asphalt roller oil spraying device includes a fixed frame, one side of which is connected to an oil tank. A pump is installed at the bottom of the oil tank, and the pump's outer casing is connected to the outer casing of the oil tank. The pump's inlet communicates with the interior of the oil tank, and the pump's outlet communicates with a fixed pipe. One end of the fixed pipe engages with the pump, and the other end communicates with a guide pipe. The bottom of the guide pipe communicates with several nozzles arranged in a row. An electric drive device is installed on one side of the guide pipe. The movable end of the electric drive device is connected to a transmission rod, and the fixed end of the electric drive device is connected to the outside of the guide pipe. Several first pistons are installed on the transmission rod. Several through holes are opened at the bottom of the guide pipe, one end of which communicates with the interior of the guide pipe, and the other end of which communicates with the inlet of the nozzle. Each first piston can seal one through hole. A through groove is opened at the top of the first piston.

[0005] To further achieve the purpose of this utility model, the following technical solution can also be adopted: the intervals between the plurality of nozzles are the same, the intervals between the plurality of first pistons are the same, and each first piston cooperates with one nozzle.

[0006] The electric push device can be a second stepper motor, with the push rod end of the electric push rod connected to the transmission rod, and the fixed end of the second stepper motor connected to the guide tube.

[0007] One side of the fixed frame is connected to a positioning plate. A brush wheel and a first stepper motor are installed on one side of the positioning plate. The housing of the first stepper motor is connected to the positioning plate. The output shaft of the first stepper motor is connected to the rotating shaft of the brush wheel. The brush of the brush wheel cooperates with the roller of the road roller. One side of the positioning plate is connected to a fixed bracket. A sleeve is installed on one side of the fixed bracket. A sleeve is fitted on the sleeve. A torsion spring is installed on one side of the sleeve. One end of the torsion spring is connected to the sleeve. The torsion spring is fitted on the sleeve. One side of the sleeve is connected to a U-shaped plate. The U-shaped plate is an inverted U-shaped plate structure. A replaceable plastic plate is installed on the U-shaped plate. The upper part of the replaceable plastic plate is inserted into the U-shaped plate. A screw hole is opened on the side of the U-shaped plate. The U-shaped plate is connected to a bolt through the screw hole. The bolt can lock the U-shaped plate and the replaceable plastic plate. One side of the replaceable plastic plate can cooperate with the roller of the road roller.

[0008] A sliding sealing ring is installed on one side of the guide tube. The transmission rod passes through the central hole of the sliding sealing ring. The outer ring of the sliding sealing ring is connected to the guide tube. The sliding sealing ring can improve the sealing between the transmission rod and the guide tube. An isolation piston is installed on the transmission rod. The isolation piston is located between the first piston and the second stepper motor. The side circumference of the isolation piston is in contact with the inner wall side circumference of the guide tube. A guide hole is opened on one side of the guide tube.

[0009] The advantages of this invention are as follows: This invention adds an oil spraying device for asphalt rollers. This device uses an electric drive to move several first pistons back and forth, causing several through-holes to open and close repeatedly. This allows the nozzle to spray intermittently, and after being evenly coated by a brush wheel and replaceable plastic plate, it reduces the amount of grease sprayed compared to existing technologies, thus avoiding excessive grease waste. This also prevents excessive anti-stick grease from being sprayed onto the rollers of the asphalt roller compared to existing technologies. Attached Figure Description

Each first piston 16 can block one through hole 17. A through groove 26 is opened on the upper part of the first piston 16.

[0013] This invention adds an asphalt roller oil spraying device. This device uses an electric drive to move several first pistons 16 back and forth, causing several through-holes 17 to open and close repeatedly. This allows the nozzle 19 to spray intermittently, and after spraying evenly through the brush wheel 6 and replaceable plastic plate 13, the amount of grease sprayed is reduced compared to the prior art 1, avoiding excessive grease waste.
