For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Please refer to Figures 1 to 3 This utility model provides an asphalt mixture specimen cutting machine, including a cutting platform 1, a cutting component 2, a water spraying component 3, and a fixing component;

[0031] The cutting platform 1 has a lower cutter 10 in the middle along the X-axis direction; the fixing component, water spraying component 3 and cutting component 2 are respectively fixed to the cutting platform 1, and the cutting component 2 is set on one side of the lower cutter 10 for cutting asphalt mixture specimens.

[0032] The water spraying end of the water spraying component 3 faces the lower cut 10 and is used to spray cooling liquid onto the asphalt mixture specimen.

[0033] The fixing assembly includes two fixing units 4, which are symmetrically arranged on both sides of the lower cut 10 with the lower cut 10 as the axis. Each fixing unit 4 includes a clamp 41 and a clamp 42. The clamp 41 is disposed on the cutting platform 1, and the clamp 42 is detachably connected to the clamp 41. The two clamps 42 cooperate with each other to form a specimen clamping area, which is used to clamp asphalt mixture specimens.

[0034] The asphalt mixture specimen cutting machine uses two fixing units 4 distributed on both sides of the lower cut slit 10 to simultaneously clamp and constrain the specimen from both sides, ensuring stable fixation and a smooth cut surface. The equipment has a simple structure, is easy to operate, and has strong applicability.

[0035] The cutting platform 1 is used to fix the cutting component 2, the water spray component 3 and the fixing component, while the lower blade slit 10 serves to avoid contact between the saw blade 24 and the cutting platform 1 during rotation, thus preventing damage to the cutting platform 1.

[0036] Cutting assembly 2 is used to cut asphalt mixture specimens. Water spraying assembly 3 is used to spray cooling liquid onto the asphalt mixture specimens to achieve the effect of cooling them. In specific applications, water is used as the cooling liquid.

[0037] The clamp 42 is detachably connected to the clamp 41. The operator can adjust the relative position of the clamps 42 according to the actual size of the asphalt mixture specimen and the cutting position of the asphalt mixture specimen in order to achieve the purpose of cutting the asphalt mixture specimen.

[0038] In one specific embodiment of this utility model, the fixing component is set on the front side of the cutting platform 1. In specific applications, the front side of the cutting platform 1 is the operating side of the operator. The tightness of the clamp 42 is controlled by the lifting eye bolt 411 facing the operator. The operator can easily turn it by hand, which is convenient and quick, improves the efficiency of specimen cutting, and optimizes the user experience.

[0039] Furthermore, the clamping device 41 includes a lifting eye bolt 411, a first fixing block 412, and a second fixing block 413;

[0040] The first fixing block 412 and the second fixing block 413 are sequentially fixed to the cutting platform 1 along the X-axis. The first fixing block 412 has a screw hole in the middle. The eye bolt 411 has a thread that matches the screw hole and is threadedly connected to the screw hole. One end of the eye bolt 411 near the second fixing block 413 passes through the screw hole and is provided with a limit block 414. The limit block 414 and the second fixing block 413 cooperate to form a clamping area to clamp the clamp 42.

[0041] The limiting block 414 can prevent the eye bolt 411 from coming off the first fixing block 412, thus preventing the eye bolt 411 from being lost; in addition, the limiting block 414 can cooperate with the second fixing block 413 to clamp the clamp 42, so as to realize the detachable connection between the clamp 41 and the clamp 42.

[0042] When fixing the clamp 42, rotate the eye bolt 411 to shorten the distance between the limit block 414 and the second fixing block 413, thereby clamping the clamp 42.

[0043] When the position of the clamp 42 needs to be adjusted, the lifting eye bolt 411 is rotated in the opposite direction so that the limiting block 414 is moved away from the second fixing block 413.

[0044] Furthermore, the clamp 42 includes a longitudinal iron plate 421 and a transverse sliding beam 422; the longitudinal iron plate 421 is disposed at one end of the transverse sliding beam 422, and the longitudinal iron plates 421 located on both sides of the lower cut slit 10 cooperate to form a specimen clamping area; the limiting block 414 and the second fixing block 413 cooperate to clamp the other end of the transverse sliding beam 422.

[0045] The longitudinal iron plates 421 located on both sides of the lower cut slit 10 are used to clamp the asphalt mixture specimen to avoid unstable clamping during cutting, which would result in uneven cutting of the specimen. The transverse sliding beam 422 is used to connect the longitudinal iron plates 421 and the clamping device 41. The other end of the transverse sliding beam 422 is clamped by the limiting block 414 and the second fixing block 413 to achieve a detachable connection between the clamping device 41 and the clamp 42.

[0046] Specifically, the cutting assembly 2 includes a motor 21, a saw arm 22, and an adjusting rod 23; the adjusting rod 23 is arranged on the cutting platform 1 along the X-axis direction, the bottom of the motor 21 is provided with a sliding seat, and the motor 21 is slidably assembled with the adjusting rod 23 through the sliding seat; one end of the saw arm 22 is connected to the motor 21, and the other end of the saw arm 22 is provided with a saw blade 24, and the motor 21 is connected to the saw blade 24 through the saw arm 22; the rotation axis of the saw blade 24 is arranged along the Y-axis direction, and the saw blade 24 is located directly above the lower cutting kerf 10.

[0047] The cutting assembly 2 can refer to existing cutting machines. The motor is connected to an external power source, and the motor provides power to rotate the circular saw blade at high speed to achieve the cutting purpose. The saw arm 22 serves to connect the motor 21 and the saw blade 24. In a specific embodiment of this utility model, the saw arm 22 can drive the saw blade 24 to move along the Z-axis, thereby enabling the cutting of asphalt mixture specimens with large heights. The lower cutting slit 10 serves to avoid contact between the saw blade 24 and the cutting platform 1 during rotation, thus preventing damage to the cutting platform 1.

[0048] Optionally, each of the two clamps 42 is provided with a scale groove along the Y-axis, and the two scale grooves are symmetrically arranged with the lower cutter 10 as the axis; a scale 43 is placed in the scale groove.

[0049] The scale slot is used to hold the scale 43, which is used to measure the distance between the edge of the longitudinal iron plate 421 and the lower cut slit 10. This allows workers to measure the length of the asphalt mixture specimen before cutting, facilitating adjustments and ensuring more standardized dimensions of the cut asphalt mixture specimen. When not in use, the scale 43 can be removed from the scale slot and stored separately to prevent damage to the scale lines caused by prolonged exposure.

[0050] Specifically, it also includes a water-shielding baffle 5, which is disposed on the side of the cutting platform 1 near the ruler groove.

[0051] The water shield 5 can block the water spraying component 3 from splashing onto the saw blade 24, preventing the cutting personnel's clothing from getting wet. In a specific embodiment of this utility model, the water shield 5 can be made of transparent materials such as glass, acrylic sheet or plastic sheet, so that the personnel can see the scale 43 through the water shield 5.

[0052] Specifically, the water spraying assembly 3 also includes a water spraying gun 31 and a water spraying bracket 32. The water spraying bracket 32 ​​is disposed on the cutting platform 1, and the water spraying gun 31 is disposed on the water spraying bracket 32. The water spraying gun 31 is connected to an external water source.

[0053] The water spray gun 31 can be connected to a faucet via a water pipe. In a specific embodiment of this utility model, the water spray direction of the water spray gun 31 is adjustable, which is used to cool the saw blade 24 when cutting the specimen.

[0054] The water spray bracket 32 ​​is used to support the water spray gun 31, so that the horizontal height of the water spray gun 31 is higher than the contact surface between the asphalt mixture specimen and the saw blade 24, which makes it easier to spray water onto the asphalt mixture specimen to achieve the purpose of cooling the asphalt mixture specimen. It can replace the manual water spraying method, which is convenient and labor-saving.

[0055] Preferably, the bottom of the cutting platform 1 is provided with square pads 11, and the square pads 11 are respectively disposed at the four corners of the cutting platform 1.

[0056] The square pads 11 are used to raise the cutting platform 1, preventing the bottom surface of the cutting platform 1 from completely touching the bottom surface, making it easier to lift or move the cutting platform 1. The square pads 11 are respectively set at the four corners of the cutting platform 1, which can make the cutting platform 1 more stable as a whole and prevent the cutting platform 1 from swaying during the cutting process, thus affecting the cutting effect.

[0057] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
