Description
Technical Field
[0001] This utility model relates to the field of asphalt modification technology, and in particular to an asphalt shearing machine. Background Technology
[0002] Modified asphalt, a widely used material in road construction, improves the properties of base asphalt by adding rubber, polymers, or other fillers. The core of this process lies in creating a three-dimensional network structure within the base asphalt through the addition of modifiers, thereby enhancing the asphalt's viscoelastic properties and high-temperature stability.
[0003] During the preparation process, a high-speed shearing machine is commonly used in the laboratory to uniformly disperse the swollen modifier particles onto the base asphalt, such as the modified asphalt shearing and heating integrated machine disclosed in utility model publication number CN220696647U. Due to the viscosity of the material, a large amount of asphalt often accumulates on the shearing head after preparation.
[0004] After use, existing shearing machines require the shearing head to be disassembled and cleaned with organic solvents (such as trichloroethylene). After cleaning, the shearing head needs to be reinstalled on the shearing machine, which is a cumbersome and inconvenient process with low cleaning efficiency. Utility Model Content

[0041] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0042] like Figure 1-4 As shown, the asphalt shearing machine of this utility model includes a worktable 1, a support assembly 2, a shearing motor 3, and a shearing head 4.
[0043] The workbench 1 is equipped with a material container placement slot 101 and a solvent storage chamber 102. A shear head inlet / outlet hole 103 is located at the top of the solvent storage chamber 102. A shear head 4 is mounted on a shearing motor 3, which selectively rotates horizontally or moves vertically above the workbench 1 via a support assembly 2. This allows the shear head 4 to selectively enter and exit the material container placement slot 101, or to enter and exit the solvent storage chamber 102 through the shear head inlet / outlet hole 103. An air outlet 104 and a cleaning cotton 11 are located on the inner wall of the shear head inlet / outlet hole 103 for cleaning the shear head 4. This structure achieves a dual-chamber design, utilizing the support assembly 2 to allow the shear head 4 to flexibly enter and exit the solvent storage chamber 102 and the material container placement slot 101. The cleaning process can be completed without disassembling the shear head 4, improving cleaning efficiency and convenience.
[0044] During the cleaning process, an appropriate amount of cleaning solvent (such as trichloroethylene) is injected into the solvent storage chamber 102. The solvent level is below the top of the shear head inlet / outlet 103 to ensure that the cleaning solvent does not overflow from the shear head inlet / outlet 103.
[0045] like Figure 4 As shown, the cleaning cotton 11 is positioned below the air outlet 104. Combined with... Figure 3 The air outlet 104 is annular in shape, and an air inlet is provided on the side of the air outlet 104 away from the inlet / outlet hole 103 of the shear head. One end of the air inlet extends to the side of the workbench 1 for connecting the air compressor's air line. This structure facilitates effective blowing and wiping of the side of the shear head 4, improving the cleaning effect. In addition, the blowing function can also help cool down during the cleaning process, preventing the equipment from being damaged due to overheating.
[0046] In addition, the air outlet 104 is designed in a ring shape, which facilitates the formation of an air curtain in the inlet and outlet holes 103 of the shear head, effectively reducing the evaporation of solvents during the cleaning process and enhancing the safety and environmental friendliness of the working environment.
[0047] like Figure 1 As shown, the support assembly 2 includes a vertical pole 21 and a clamp 22. The vertical pole 21 is fixedly mounted vertically on the top of the workbench 1; one end of the clamp 22 is clamped and fixed to the vertical pole 21, and the other end is fixedly connected to the shearing motor 3. Figure 3 The clamp 22 includes a slider 221, a cross arm 222, and a locking bolt 223. The slider 221 has a through hole 22101 through which the upright rod 21 passes. One end of the cross arm 222 is fixed to the slider 221, and the other end is fixed to the shearing motor 3. The locking bolt 223 is screwed onto the slider 221, and one end of the locking bolt 223 extends into the through hole 22101 to abut against the side of the upright rod 21.
[0048] Tightening the locking bolt 223 disengages its end from the side of the upright 21, unlocking the clamp 22. The clamp can then rotate horizontally or slide vertically on the upright 21 to adjust the position of the shear head 4. Once the locking bolt 223 is tightened, the clamp 22 is locked and fixed to the upright 21 to maintain the position of the shear head 4.
[0049] like Figure 1 As shown, the solvent storage chamber 102 is equipped with a solvent inlet 105 and a solvent outlet 106. The solvent inlet 105 is connected to an injection pump 52 via a pipe, and the solvent outlet 106 is connected to a suction pump 51 via a pipe. The suction pump 51 and the injection pump 52 have the same head, and both are connected to the filter tank 5 via pipes. This structure facilitates the filtration of impurities in the solvent and promotes the circulation of clean solvent within the solvent storage chamber 102, further improving the cleaning effect of the shear head 4.
[0050] The filter tank 5 has an internal cavity containing a filter screen. One end of the cavity has an outlet connected to a liquid injection pump 52 via a pipe, and the other end has a return outlet connected to a liquid pump 51 via a pipe. The filter screen, located between the return and outlet, filters the cleaning solvent entering the cavity. The filtered cleaning solvent is then re-injected into the solvent storage chamber 102 by the liquid injection pump 52.
[0051] In addition, the solvent outlet 106 extends vertically through the bottom of the solvent storage chamber 102, facilitating the discharge of contaminants from the solvent storage chamber 102.
[0052] In addition, the rectangular array at the bottom of the workbench 1 has several support legs 12, which facilitates the installation of pipes at the solvent outlet 106, increasing the convenience and flexibility of use.
[0053] like Figure 1 As shown, a cleaning motor 13 and a roller brush 14 are also provided inside the solvent storage chamber 102. The roller brush 14 is positioned at the bottom of the solvent storage chamber 102 via the cleaning motor 13 and is used to clean the shear head 4. Figure 4 The roller brush 14 is arranged vertically, and there are several roller brushes arranged in a circular array along the circumferential direction of the shear head inlet and outlet hole 103.
[0054] The cleaning motor 13 drives the roller brush 14 to rotate horizontally. The roller brush 14 can not only brush the shear head 4, but also generate a turbulence effect, which makes the cleaning effect of the shear head 4 better.
[0055] In addition, the cleaning motor 13 can also be installed at the bottom of the workbench 1, with the output shaft of the cleaning motor 13 extending into the solvent storage cavity 102 and connected to the roller brush 14.
[0056] like Figure 1 As shown, the interior of the material container placement slot 101 is used to place a container, which is then used to hold materials. A heating coil 15 and a heating wire 16 are installed at the bottom of the material container placement slot 101 to heat the materials in the container. The heating coil 15 and the heating wire 16 are connected to a thermostat 17 via wires, and the thermostat 17 is used to achieve constant temperature heating.
[0057] The method of using the asphalt shearing machine of this utility model is as follows:
[0058] When shearing materials, unlock clamp 22, then slide or rotate clamp 22 to move shear head 4 into the material, and then lock clamp 22. Shear motor 3 drives shear head 4 to rotate and shear materials.
[0059] When cleaning the shear head 4, compressed air is supplied to the air outlet 104 by the air compressor to form an air curtain inside the inlet and outlet hole 103 of the shear head. The injection pump 52 is started to inject cleaning solvent into the solvent storage chamber 102. When the cleaning solvent fills the solvent storage chamber 102, the pump 51 is started. The pumping and injection are carried out simultaneously (that is, the pump 51 extracts the cleaning solvent from the solvent storage chamber 102, and the injection pump 52 replenishes the solvent storage chamber 102 with an equal amount of cleaning solvent). This allows the cleaning solvent in the solvent storage chamber 102 to circulate and maintain the required liquid level.
[0060] Unlock clamp 22 again. At this point, the shear head 4 can remain rotating, or the shearing motor 3 can be stopped. Then, move the shear head 4 into the shear head inlet / outlet hole 103, and then into the bottom of the solvent storage chamber 102, immersing the shear head 4 completely in the cleaning solvent and bringing it into contact with the roller brush 14. During this movement, the air outlet 104 blows air onto the shear head 4, and the cleaning cotton 11 brushes it. After insertion, lock clamp 22 again to keep the shear head 4 in the cleaning solvent, allowing the flowing cleaning solvent to rinse it. Then, start the cleaning motor 13 to rotate the roller brush 14, which then brushes the shear head 4. After cleaning, repeat the above steps to remove the shear head 4 from the shear head inlet / outlet hole 103.
[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
