Description

Technical Field

[0001] This utility model relates to the field of asphalt preparation technology, specifically a shearing machine for preparing UV-resistant aging asphalt. Background Technology

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form. It has a black surface and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is a waterproof, moisture-proof, and corrosion-resistant organic cementing material. Asphalt can be mainly divided into three types: coal tar pitch, petroleum asphalt, and natural asphalt. The asphalt needs to be sheared during the asphalt preparation process. The asphalt shearing is carried out by an asphalt shearing machine. The rotor of the shearing machine highly agitates the asphalt to achieve the shearing of the asphalt.

[0003] The shearing motion of the asphalt shearing machine is unidirectional, which results in a longer shearing time for asphalt and thus a longer asphalt preparation time. Therefore, it does not meet the current requirements. To address this, we propose a shearing machine for preparing asphalt that is resistant to UV aging. Utility Model Content

[0004] The purpose of this invention is to provide a shearing machine for preparing UV-resistant aging asphalt, in order to solve the problem mentioned in the background art that the shearing motion direction of the asphalt shearing machine is unidirectional, which leads to the asphalt shearing taking a long time and thus prolonging the asphalt preparation time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shearing machine for preparing UV-resistant aging asphalt, comprising a shearing barrel, a support plate fixed to the top of the shearing barrel, a motor mounting bracket fixed to the upper surface of the support plate, a shearing motor fixed to the inner side of the motor mounting bracket, a shearing shaft fixed to the output shaft of the shearing motor facing downwards, the shearing shaft penetrating the support plate, two symmetrically distributed auxiliary shafts rotatably mounted on the outer side of the support plate, a shearing propeller fixed to the outer surface of the auxiliary shaft, the shearing propellers being spirally distributed on the outer surface of the auxiliary shafts, and a shearing hole penetrating the surface of the shearing propellers, a discharge pipe fixed to the bottom end of the shearing barrel, and a solenoid valve provided on the inner side of the top end of the discharge pipe.

[0006] Preferably, a support ring is fixed to the top outer surface of the shearing shaft, and a ball bearing is installed at the bottom of the support ring, with the support ring and the support plate in rolling contact via the ball bearing.

[0007] Preferably, an auxiliary motor is fixed inside the shearing shaft, and an output bevel gear is fixed to the output shaft end of the auxiliary motor.

[0008] Preferably, the auxiliary shaft has a transmission bevel gear fixed to its end face inside the shearing shaft, and the transmission bevel gear meshes with the output bevel gear.

[0009] Preferably, the auxiliary rotating shaft has an annular groove on the outer side of the end where the transmission bevel gear is located, and an alloy sealing ring is installed inside the annular groove. The outer edge of the alloy sealing ring is rotatably engaged inside the shearing rotating shaft.

[0010] Preferably, the top of the shearing shaft is provided with a heat dissipation hole, the bottom end of the heat dissipation hole extends to the position of the auxiliary motor, and the top inner side of the heat dissipation hole is provided with a dustproof and breathable block, the dustproof and breathable block includes gauze and activated carbon, with the activated carbon wrapped inside the gauze.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes an auxiliary motor and an output bevel gear to drive a transmission bevel gear during the rotation of the shearing shaft, which in turn drives the auxiliary shaft and the shearing propeller. This causes the transmission bevel gear to rotate, thereby enabling the auxiliary shaft and the shearing propeller to rotate. The rotating shearing propeller then facilitates the flow exchange of asphalt located at the edge and center of the shearing barrel, accelerating the asphalt mixing efficiency. Furthermore, as the asphalt is conveyed by the shearing propeller, it is sheared through the shearing holes, thus improving the asphalt shearing efficiency. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1 to 4 As shown, a shearing machine for preparing UV-resistant aging asphalt includes a shearing barrel 1. A support plate 4 is fixed to the top of the shearing barrel 1. A motor mounting bracket 5 is fixed to the upper surface of the support plate 4. A shearing motor 3 is fixed to the inner side of the motor mounting bracket 5. The output shaft end of the shearing motor 3 faces downward and is fixed with a shearing shaft 7. The shearing shaft 7 passes through the support plate 4. Two symmetrically distributed auxiliary shafts 9 are rotatably installed on the outer side of the support plate 4. A shearing propeller 8 is fixed to the outer surface of the auxiliary shaft 9. The shearing propeller 8 is spirally distributed on the outer surface of the auxiliary shaft 9, and a shearing hole 10 is provided through the surface of the shearing propeller 8. A discharge pipe 11 is fixed through the bottom end of the shearing barrel 1. A solenoid valve is provided on the inner side of the top end of the discharge pipe 11. The shearing motor 3 drives the shearing shaft 7, the shearing propeller 8 and the auxiliary shafts 9 to rotate around the axis of the shearing shaft 7, thereby shearing and stirring the asphalt inside the shearing barrel 1 to promote asphalt mixing.

[0020] A support ring 6 is fixed to the top outer surface of the shearing shaft 7. A ball bearing is installed at the bottom of the support ring 6. The support ring 6 and the support plate 4 are in rolling contact through the ball bearing. The support ring 6 supports the shearing shaft 7 and ensures that the rotation of the shearing shaft 7 is not affected.

[0021] An auxiliary motor 12 is fixed inside the shearing shaft 7. An output bevel gear 15 is fixed to the output shaft end of the auxiliary motor 12. A transmission bevel gear 16 is fixed to the end face of the auxiliary shaft 9 inside the shearing shaft 7. The transmission bevel gear 16 meshes with the output bevel gear 15. The auxiliary motor 12 and the output bevel gear 15 drive the transmission bevel gear 16 to rotate, so that the transmission bevel gear 16 drives the auxiliary shaft 9 and the shearing propeller 8 to rotate. Thus, the rotating shearing propeller 8 is used to exchange the asphalt located at the edge and center of the shearing barrel 1.

[0022] The auxiliary shaft 9 is provided with an annular groove on the outer side of the end of the transmission bevel gear 16. An alloy sealing ring 2 is installed inside the annular groove. The outer edge of the alloy sealing ring 2 is rotatably engaged inside the shear shaft 7. The alloy sealing ring 2 is used to fill the gap between the auxiliary shaft 9 and the shear shaft 7 to prevent asphalt from entering the interior of the shear shaft 7 along the gap.

[0023] The top of the shear shaft 7 is provided with a heat dissipation hole 13, the bottom end of which extends to the position of the auxiliary motor 12. The top inner side of the heat dissipation hole 13 is provided with a dustproof and breathable block 14, which includes gauze and activated carbon. The activated carbon is wrapped inside the gauze. The heat dissipation hole 13 ensures that the heat generated by the auxiliary motor 12 during operation can be dissipated outward, while the dustproof and breathable block 14 ensures that dust or moisture in the air will not enter the interior of the heat dissipation hole 13.

[0024] Working principle: First, the asphalt raw material to be sheared is placed inside the shearing barrel 1. Then, the power supply of the device is turned on and started. After the device is started, the shearing motor 3 drives the shearing shaft 7, the shearing propeller 8, and the auxiliary shaft 9 to rotate around the axis of the shearing shaft 7. The auxiliary shaft 9 and the shearing propeller 8 drive the raw material to be stirred inside the shearing barrel 1, so that the raw material is sheared and mixed. At the same time, the power supply of the auxiliary motor 12 is turned on and started. The auxiliary motor 12 drives the transmission bevel gear 16 and the auxiliary shaft 9 to rotate around the axis of the auxiliary shaft 9 through the output bevel gear 15, so that the shearing propeller 8 makes a spiral motion. The shearing propeller 8 in the spiral motion exchanges the asphalt raw material in the center and the edge of the shearing barrel 1. During the exchange process, some raw material passes through the shearing hole 10 and is sheared, which accelerates the mixing efficiency of asphalt. At the same time, the asphalt is conveyed by the shearing propeller 8 and is sheared through the shearing hole 10, thereby improving the asphalt shearing efficiency.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
