Description

Technical Field

[0001] This utility model relates to the field of asphalt testing technology, and in particular to a rapid and intelligent testing device for asphalt mixture gradation. Background Technology

[0002] Asphalt gradation testing refers to the inspection of the proportions of each grade in an asphalt mixture to ensure that it meets the design requirements. The gradation of an asphalt mixture refers to the proportion of mineral aggregates of different particle sizes in the mixture. A reasonable gradation can ensure the performance and durability of asphalt pavement. Gradation testing is one of the important testing steps before asphalt paving.

[0003] The existing asphalt mixture gradation testing operation has the following drawbacks: the existing asphalt mixture gradation testing operation requires manual input of asphalt samples into a vibrating screen for gradation and sieving. After the sieving is completed, different screens must be removed in sequence and the asphalt material inside must be poured out for weighing and calculation. The operation process is cumbersome and time-consuming. To address this, we propose a rapid and intelligent asphalt mixture gradation testing device. Utility Model Content

[0004] The main purpose of this utility model is to provide a rapid and intelligent testing device for asphalt mixture gradation. Through the testing mechanism set on the top of the base, it can realize automatic weighing and testing after asphalt sieving, improve the efficiency of mix proportion testing, and effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rapid intelligent testing device for asphalt mixture gradation includes a base and a testing mechanism. The testing mechanism is located on the top of the base and includes a vibrating screen, a screen box, slots, cylinder A, a vertical rod, a sliding sleeve, a spring, a baffle, a screen plate, cylinder B, a movable rod, a tray, and a weighing sensor. The vibrating screen is installed on one side of the top of the base. The screen box is snapped into the top of the vibrating screen, and slots are provided on one side of the surface of the screen box. Cylinder A is installed on the top of the base at the bottom position of the vibrating screen, and a vertical rod is installed at the power output end of cylinder A. A sliding sleeve is sleeved around the outer periphery of the vertical rod, and a baffle is movably connected to one side of the sliding sleeve via a spring. A screen plate inserted into the slot is fixedly connected to the side of the baffle away from the sliding sleeve. Cylinder B is installed on the top of the base, and a movable rod is installed at the power output end of cylinder B. A tray corresponding to the position of the screen plate is installed on the side of the movable rod facing the vibrating screen, and a weighing sensor is built into the tray.

[0007] Furthermore, it also includes an adjustment mechanism. An adjustment mechanism is provided at the connection between the movable rod and the tray. The adjustment mechanism includes a screw groove, a screw sleeve, and a connecting rod. The outer wall of the movable rod has a screw groove, and a screw sleeve is screwed into the screw groove. The surface of the screw sleeve is connected to the side of the tray through the connecting rod. The outer periphery of the movable rod is movably connected to the screw sleeve through the screw groove. The screw sleeve can be turned along the screw groove structure. The outer periphery of the screw sleeve is connected to the tray structure through the connecting rod. Before the testing operation, the screw sleeve can be turned along the outer periphery of the movable rod to adjust its vertical height and spacing, thereby adjusting the vertical direction and spacing of the tray, so that the tray and the screen plate are aligned and can be inserted into the bottom of the screen plate for weighing. The number of trays can be flexibly increased or decreased according to the number of different screen plates.

[0008] Furthermore, a rubber pad is bonded to the outer periphery of the baffle, and a movable groove is formed on the surface of the sliding sleeve near the spring. A limiting rod that passes through the spring and extends into the movable groove is fixedly connected to the surface of the baffle. When the screen plate is inserted into the slot and is in place, the baffle and the end of the slot are aligned. The rubber pad at the connection point can improve the sealing of the connection point and maintain the stability of the screen plate position. The end of the limiting rod is inserted into the movable groove, which does not affect the vibration of the screen plate, and at the same time can drive the screen plate to move through the limiting rod.

[0009] Furthermore, a controller is mounted on one side of the base surface, and a signal receiver is mounted on one side of the controller surface. A calculation module is mounted on the controller surface at the bottom of the signal receiver. The signal output terminal of the weighing sensor is connected to the calculation module through the signal receiver, and the communication terminal of the calculation module is connected to the communication terminal of the controller. After the weighing sensor weighs the data, it transmits the data to the signal receiver, and then the calculation module performs tare calculation. The calculated result is transmitted to the controller for display.

[0010] Furthermore, a movable sleeve is fitted around the outer periphery of the threaded sleeve, and the end of the connecting rod away from the tray is welded to the surface of the movable sleeve; the movable sleeve can rotate around the outer periphery of the threaded sleeve, thereby facilitating the rotation and adjustment of the tray's position.

[0011] Compared with the prior art, this utility model has the following beneficial effects: Before the testing operation, the tray is used to contact the bottom of the screen plate to weigh the screen plate in a material-free state and automatically record the weight data of each level of screen plate. The controller can preset the operating data of each component. The operation of cylinder A drives the screen plate to be inserted into the screen box through the upright rod. The cooled asphalt is put into the screen box and subjected to high-frequency vibration screening by the vibrating screener, so that the asphalt material is graded in the screen box. During the vibration screening process, the tray is away from the vibrating screener and does not affect its operation. After screening is completed, the control cylinder A is operated to slowly pull out the screen plate. When it is pulled out to a certain distance, the cylinder B is operated to move the tray to the bottom of the screen plate and align it with the bottom of the screen plate. At this time, the screen plate continues to be pulled out. When it is completely separated from the screen box, the screen plate will follow the... The upright pole slides down, carrying the asphalt material onto the top of the tray. A weighing sensor is used to measure the weight, and the weight of the screen plate in its empty state is subtracted from the measured weight to obtain the weight of the asphalt material at the top of each screen plate. This completes the gradation calculation, improving testing efficiency and reducing manual labor. A threaded sleeve is movably connected to the outer circumference of the movable rod via a threaded groove. The sleeve can be turned along the threaded groove structure. The outer circumference of the sleeve is connected to the tray structure via a connecting rod. Before testing, the sleeve can be turned along the outer circumference of the movable rod to adjust its vertical height and spacing, thereby adjusting the vertical direction and spacing of the tray. This ensures the tray is aligned with the screen plate and can be inserted precisely into the bottom of the screen plate for weighing. The number of trays can be flexibly increased or decreased depending on the number of screen plates. Attached Figure Description

The testing mechanism 2 is mounted on the top of the base 1. The testing mechanism 2 includes a vibrating screen 201, a screen box 202, a slot 203, a cylinder A 204, a vertical rod 205, a sliding sleeve 206, a spring 207, a baffle 208, a screen plate 209, a cylinder B 213, a movable rod 214, a tray 215, and a weighing sensor 216. The vibrating screen 201 is mounted on one side of the top of the base 1. The screen box 202 is snapped into the top of the vibrating screen 201, and slots 203 are provided on one side of the surface of the screen box 202. The top of the base 1 is located at the top of the vibrating screen 201. A cylinder A204 is installed at the bottom position, and a vertical rod 205 is installed at the power output end of the cylinder A204. A sliding sleeve 206 is sleeved on the outer periphery of the vertical rod 205, and a baffle 208 is movably connected to one side of the surface of the sliding sleeve 206 via a spring 207. A screen plate 209 inserted into the slot 203 is fixedly connected to the side of the surface of the baffle 208 away from the sliding sleeve 206. A cylinder B213 is installed at the top of the base 1, and a movable rod 214 is installed at the power output end of the cylinder B213. A tray 215 corresponding to the position of the screen plate 209 is installed on the side of the movable rod 214 facing the vibrating screen 201, and a weighing sensor 216 is built into each tray 215.

[0020] The system also includes an adjustment mechanism 3. An adjustment mechanism 3 is provided at the connection between the movable rod 214 and the tray 215. The adjustment mechanism 3 includes a threaded groove 301, a threaded sleeve 302, and a connecting rod 304. The outer wall of the movable rod 214 has a threaded groove 301, and the threaded sleeve 302 is screwed into the threaded groove 301. The surface of the threaded sleeve 302 is connected to the side of the tray 215 via the connecting rod 304. The outer periphery of the movable rod 214 is movably connected to the threaded sleeve 302 through the threaded groove 301. Following the structure of the threaded groove 301... The screw sleeve 302 can be screwed. The outer periphery of the screw sleeve 302 is connected to the tray 215 structure through the connecting rod 304. Before the inspection operation, the screw sleeve 302 can be screwed along the outer periphery of the movable rod 214 to adjust its vertical height and spacing, thereby adjusting the vertical direction and spacing of the tray 215, so that the tray 215 corresponds to the position of the sieve plate 209 and can be inserted into the bottom of the sieve plate 209 to weigh the sieve plate 209. The number of trays 215 can be flexibly increased or decreased according to the number of different sieve plates.

[0021] The baffle 208 has an adhesive pad 210 bonded to its outer periphery. The sliding sleeve 206 has a movable groove 211 on its surface near the spring 207. A limiting rod 212, penetrating the spring 207 and extending into the movable groove 211, is fixedly connected to the surface of the baffle 208. A controller 217 is mounted on one side of the base 1, and a signal receiver 218 is mounted on one side of the controller 217. A calculation module 219 is mounted on the surface of the controller 217 at the bottom of the signal receiver 218. The signal output terminal of the weighing sensor 216 is connected to the calculation module 219 through the signal receiver 218. The communication terminal of module 219 is connected to the communication terminal of controller 217. When the sieve plate 209 is inserted into the slot 203 and is in place, the baffle 208 is aligned with the end of the slot 203. The rubber pad 210 is located at the connection point to improve the sealing of the connection point and maintain the stability of the sieve plate position. The end of the limit rod 212 is inserted into the movable groove 211, which does not affect the vibration of the sieve plate, and at the same time can drive the movement of the sieve plate through the limit rod 212. After the weighing sensor 216 weighs the sieve plate, it transmits the data to the signal receiver 218. Then, the calculation module 219 performs the tare calculation, and the calculated result is transmitted to the controller 217 for display.

[0022] The threaded sleeve 302 is fitted with a movable sleeve 303 on its outer periphery, and the end of the connecting rod 304 away from the tray 215 is welded to the surface of the movable sleeve 303; the movable sleeve 303 can rotate on the outer periphery of the threaded sleeve 302, thereby facilitating the rotation and adjustment of the position of the tray 215.

[0023] It should be noted that this utility model is a rapid intelligent testing device for asphalt mixture gradation. During operation, before testing, the tray 215 contacts the bottom of the screen plate 209 to weigh the screen plate 209 in a material-free state and automatically records the weight data of each level of screen plate 209. The controller 217 can preset the operating data of each component. The cylinder A204 drives the screen plate 209 to insert into the screen box 202 via the upright rod 205. The cooled asphalt is then fed into the screen box 202. In section 02, the asphalt material undergoes high-frequency vibration screening by the vibrating screener 201, allowing it to be graded within the screen box 202. During the screening process, the tray 215 remains away from the vibrating screener 201 to avoid affecting its operation. After screening, the control cylinder A204 operates to slowly pull out the screen plate 209. Once a certain distance has been removed, the cylinder B213 operates to move the tray 215 to the bottom of the screen plate 209 and align it with the bottom of the screen plate 209. At this point, the screen plate 209 continues to be pulled out until it is completely separated from the screen box 202. The sieve plate 209 slides down the upright 205, carrying the asphalt material onto the top of the tray 215. Weighing is performed using the weighing sensor 216, and the weight of the sieve plate 209 in its empty state is subtracted from the weighing data to obtain the weight of the asphalt material at the top of each sieve plate 209. This completes the gradation calculation, improving testing efficiency and reducing manual labor. The outer periphery of the movable rod 214 is movably connected to the threaded sleeve 302 via the threaded groove 301. The threaded sleeve 302 can be adjusted along the structure of the threaded groove 301. The screw sleeve 302 is connected to the tray 215 structure via the connecting rod 304. Before the inspection operation, the screw sleeve 302 can be turned along the outer periphery of the movable rod 214 to adjust its vertical height and spacing, thereby adjusting the vertical direction and spacing of the tray 215, so that the tray 215 corresponds to the position of the sieve plate 209 and can be inserted into the bottom of the sieve plate 209 to weigh the sieve plate 209. The number of trays 215 can be flexibly increased or decreased according to the number of different sieve plates.
