Description

Technical Field

[0001] The utility model belongs to the field of construction devices for coarse aggregates of large-size cement stabilized macadam base course, and particularly relates to a construction device for coarse aggregates of large-size cement stabilized macadam base course. Background Technique

[0002] Coarse aggregates of large-size cement stabilized macadam base course are a commonly used road base material. It is composed of large-size crushed stones and cement mixed together, and has high strength and stability, which can effectively increase the bearing capacity and anti-deformation ability of the road base. The preparation process of coarse aggregates of large-size cement stabilized macadam base course is relatively simple. The large-size crushed stones and an appropriate amount of cement are fully mixed and stirred by a mixer so that the cement fully coats the surface of the crushed stones. In the prior art, when the coarse aggregates of large-size cement stabilized macadam base course in the device need to be discharged, the device has no anti-blocking mechanism, and the coarse aggregates of large-size cement stabilized macadam base course may be blocked in the discharge port, resulting in a reduction in working efficiency. Moreover, when the scraper on the device is used for a long time, the scraper may be worn out, resulting in the scraper on the device being unable to be used continuously. Therefore, it is necessary to improve the prior art. Summary of the Invention

[0003] The purpose of the utility model is to provide a construction device for coarse aggregates of large-size cement stabilized macadam base course, which solves the problems that when the coarse aggregates of large-size cement stabilized macadam base course in the device need to be discharged, the device has no anti-blocking mechanism, and the coarse aggregates of large-size cement stabilized macadam base course may be blocked in the discharge port, resulting in a reduction in working efficiency, and when the scraper on the device is used for a long time, the scraper may be worn out, resulting in the scraper on the device being unable to be used continuously.

[0004] To achieve the above purpose, the utility model provides a construction device for coarse aggregates of large-size cement stabilized macadam base course, including a housing. A support column is fixedly connected to the bottom of the housing. A discharge port is fixedly sleeved inside the housing. A valve body is arranged on the discharge port. An anti-blocking mechanism is arranged at the bottom of the housing. A top cover is threadedly connected to the outside of the housing. A stirring mechanism is arranged on the top cover. The anti-blocking mechanism includes a first motor. The first motor is fixedly installed at the bottom of the housing. A first screw rod is fixedly connected to the bottom of the rotating shaft of the first motor. A threaded block is threadedly connected to the outside of the first screw rod. A guiding block is fixedly connected to the threaded block. A vibrating machine is fixedly installed on the threaded block. The vibrating machine contacts the discharge port. By starting the vibrating machine and the first motor, the first motor drives the first screw rod and the threaded block to perform threaded movement. The movement of the threaded block drives components such as the vibrating machine to move. The vibrating machine vibrates while moving to vibrate the discharge port, thereby preventing the coarse aggregates of large-size cement stabilized macadam base course from being blocked in the discharge port and preventing the reduction of the working efficiency of the device.

[0005] The principle of this utility model is as follows: When the device is in use, the coarse aggregate of the large-sized cement stabilized macadam base course is poured into the interior of the housing from the feed inlet on the top cover, and then the second motor is started. The second motor drives the rotating column to rotate, and the rotation of the rotating column drives components such as the fixed sleeve, connecting sleeve, and scraper to rotate to stir the coarse aggregate of the large-sized cement stabilized macadam base course, so that the coarse aggregate of the large-sized cement stabilized macadam base course is stirred;

[0006] When the coarse aggregate of the large-sized cement stabilized macadam base course in the device needs to be discharged, rotate the valve body, and the coarse aggregate of the large-sized cement stabilized macadam base course is discharged from the discharge port. Then start the vibrator and the first motor. The first motor drives the first screw rod to rotate. The rotation of the first screw rod has a threaded movement with the threaded block, and thus causes the threaded block to have a relative displacement. The movement of the threaded block drives the guide block and the vibrator to move. The vibrator vibrates while moving to vibrate the discharge port, thereby preventing the coarse aggregate of the large-sized cement stabilized macadam base course from being blocked in the discharge port and preventing the working efficiency of the device from decreasing;

[0007] When the scraper on the device is used for a long time, rotate the second screw rod. The rotation of the second screw rod has a threaded movement with the sliding sleeve, and thus causes the sliding sleeve to have a relative displacement. The movement of the sliding sleeve drives the scraper to move. The movement of the scraper drives the guide rod to move. The scraper moves into contact with the inner wall of the housing, so that the scraper on the device can continue to be used.

[0008] The beneficial effects of this utility model are as follows: In this solution, by designing components such as the second motor, rotating column, fixed sleeve, sliding sleeve, second screw rod, and scraper, the rotation of the second screw rod has a threaded movement with the sliding sleeve, and the movement of the sliding sleeve drives components such as the scraper to move. The scraper moves into contact with the inner wall of the housing, so that the scraper on the device can continue to be used. By designing components such as the first motor, first screw rod, rotating block, threaded block, guide block, and connecting plate, start the vibrator and the first motor. The first motor drives the first screw rod to have a threaded movement with the threaded block, and the movement of the threaded block drives components such as the vibrator to move. The vibrator vibrates while moving to vibrate the discharge port, thereby preventing the coarse aggregate of the large-sized cement stabilized macadam base course from being blocked in the discharge port and preventing the working efficiency of the device from decreasing.

[0009] Further, a rotating block is fixedly connected to the bottom of the first screw rod. The rotating block is made of iron material. By designing the rotating block to be made of iron material, the rotating block is made more durable.

[0010] Further, a connecting plate is fixedly connected to the bottom of the housing. A guide block is slidably connected inside the connecting plate. By designing the connecting plate, the guide block can be guided.

By rotating the second screw rod, a threaded movement occurs between the second screw rod and the sliding sleeve, and the movement of the sliding sleeve drives components such as the scraping plate to move. The movement of the scraping plate contacts the inner wall of the housing, enabling the scraping plate on the device to continue to be used.

[0012] Further, the inside of the sliding sleeve is threadedly connected with a second screw rod, and the second screw rod is movably connected to the fixed sleeve. By designing the second screw rod, a threaded movement can occur between the second screw rod and the sliding sleeve.

The bottom of the rotating shaft of the first motor 51 is fixedly connected to a first screw rod 52. The bottom of the first screw rod 52 is fixedly connected to a rotating block 53. The rotating block 53 is made of iron material. By designing the rotating block 53 to be made of iron material, the rotating block 53 is made more durable. A threaded block 54 is threadedly connected to the outside of the first screw rod 52. A guide block 55 is fixedly connected to the threaded block 54. A connecting plate 56 is fixedly connected to the bottom of the housing 1. The guide block 55 is slidably connected inside the connecting plate 56. By designing the connecting plate 56, the guide block 55 can be guided. A vibrator 57 is fixedly installed on the threaded block 54. The vibrator 57 contacts the discharge port 3. By starting the vibrator 57 and the first motor 51, the first motor 51 drives the first screw rod 52 to perform a threaded movement with the threaded block 54. The movement of the threaded block 54 drives components such as the vibrator 57 to move. The vibrator 57 vibrates while moving to vibrate the discharge port 3, thereby preventing the coarse aggregate of the large-size cement stabilized macadam base from being blocked in the discharge port 3 and preventing the working efficiency of the device from decreasing.

[0023] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 5As shown in the figure, the stirring mechanism 7 includes a second motor 71. The second motor 71 is fixedly installed on the top of the top cover 6. The rotating shaft of the second motor 71 is rotatably connected to the top cover 6. The bottom of the rotating shaft of the second motor 71 is fixedly connected to a rotating column 72. A fixed sleeve 73 is fixedly connected to the outside of the rotating column 72. A sliding sleeve 74 is slidably connected to the inside of the fixed sleeve 73. A second screw rod 75 is threadedly connected to the inside of the sliding sleeve 74. The second screw rod 75 is movably connected to the fixed sleeve 73. By designing the second screw rod 75, a threaded movement can occur with the sliding sleeve 74. The second screw rod 75 is connected to the inside of the rotating column 72 through a bearing.

A guide rod 78 is slidably connected to the inside of the connecting sleeve 77. A scraping plate 76 is fixedly connected to the guide rod 78. By designing the guide rod 78, the scraping plate 76 can be guided. The scraping plate 76 contacts the housing 1.

The movement of the scraping plate 76 contacts the inner wall of the housing 1, enabling the scraping plate 76 on the device to continue to be used.

[0024] The specific implementation process of the present utility model is as follows: When the device is in use, the coarse aggregate of the large particle size cement stabilized macadam base is poured into the inside of the housing 1 from the feed port on the top cover 6, and then the second motor 71 is started. The second motor 71 drives the rotating column 72 to rotate. The rotation of the rotating column 72 drives components such as the fixed sleeve 73, the connecting sleeve 77, and the scraping plate 76 to rotate to stir the coarse aggregate of the large particle size cement stabilized macadam base, so that the coarse aggregate of the large particle size cement stabilized macadam base is stirred.

[0025] When the coarse aggregate of the large particle size cement stabilized macadam base in the device needs to be discharged, the valve body 4 is rotated, and the coarse aggregate of the large particle size cement stabilized macadam base is discharged from the discharge port 3. Then the vibrator 57 and the first motor 51 are started. The first motor 51 drives the first screw rod 52 to rotate. The rotation of the first screw rod 52 has a threaded movement with the threaded block 54, thereby causing the threaded block 54 to have a relative displacement. The movement of the threaded block 54 drives the guide block 55 and the vibrator 57 to move. The vibrator 57 vibrates while moving to vibrate the discharge port 3, thereby preventing the coarse aggregate of the large particle size cement stabilized macadam base from being blocked in the discharge port 3 and preventing the working efficiency of the device from being reduced.

[0026] When the scraping plate 76 on the device is used for a long time, the second screw rod 75 is rotated. The rotation of the second screw rod 75 has a threaded movement with the sliding sleeve 74, thereby causing the sliding sleeve 74 to have a relative displacement. The movement of the sliding sleeve 74 drives the scraping plate 76 to move. The movement of the scraping plate 76 drives the guide rod 78 to move. The movement of the scraping plate 76 contacts the inner wall of the housing 1, enabling the scraping plate 76 on the device to continue to be used.

[0027] In this solution, by designing components such as the second motor 71, rotating column 72, fixed sleeve 73, sliding sleeve 74, second screw 75, and scraper 76, when the second screw 75 rotates, a threaded movement occurs between the second screw 75 and the sliding sleeve 74. The movement of the sliding sleeve 74 drives components such as the scraper 76 to move. When the scraper 76 moves and contacts the inner wall of the housing 1, the scraper 76 on the device can continue to be used. By designing components such as the first motor 51, first screw 52, rotating block 53, threaded block 54, guide block 55, and connecting plate 56, when the vibrator 57 and the first motor 51 are started, the first motor 51 drives a threaded movement between the first screw 52 and the threaded block 54. The movement of the threaded block 54 drives components such as the vibrator 57 to move. The vibrator 57 vibrates while moving to vibrate the discharge port 3, thereby preventing coarse aggregates of the large particle size cement stabilized macadam base from clogging in the discharge port 3 and preventing the working efficiency of the device from decreasing.
