[0033] See also Figures 1 to 4, A compaction device for cement stabilized macadam base layer in this embodiment includes a rammer main body 1, a controller 2 fixedly installed outside the rammer main body 1, and a handle 3 arranged on the upper surface of the rammer main body 1. An angle adjustment mechanism 4 for adjusting the tilt angle of the handle 3 is arranged at the top of the rammer main body 1, and an adjustment mechanism 5 for adjusting the telescopic length of the handle 3 is arranged at the top of the rammer main body 1. The angle adjustment mechanism 4 includes a mounting seat 41 fixedly connected to the top of the rammer main body 1, a rotating shaft 42 rotatably connected to the inside of the mounting seat 41 and extending to its outside, a rotating seat 43 fixedly connected to the outside of the rotating shaft 42, a driven gear 47 fixedly connected to one end of the rotating shaft 42 away from the mounting seat 41, and a speed regulating motor 45 arranged outside the mounting seat 41.

[0034] Start the speed regulating motor 45 to work through the controller 2 to drive the transmission gear 46 to rotate, so that the transmission gear 46 rotates and meshes to drive the driven gear 47, the rotating shaft 42 and the rotating seat 43 to adjust the rotation angle. The rotating seat 43 drives the handle 3 to adjust the tilt angle through the adjustment mechanism 5 to adapt to the operation habits of different operators and construction conditions, achieving the advantage of being convenient to adjust the angle of the handle according to needs. By setting the angle adjustment mechanism 4, the handle 3 can be adjusted in angle, and through the action of the angle adjustment mechanism 4, a rotational force can be given to the handle 3. When the device is not in use, it can drive the handle 3 to rotate to make the handle 3 flush with the ground, reducing the space occupied by the device and facilitating the placement of the device.

[0035] Among them, the mounting seat 41 is in a U-shaped shape. A bearing adapted to the rotating shaft 42 is fixedly installed inside the mounting seat 41, and the outer diameter of the rotating seat 43 is adapted to the inner diameter of the mounting seat 41. By setting the bearing, the stability of the rotating shaft 42 during rotation adjustment is effectively improved. Start the speed regulating motor 45 to work through the controller 2 to drive the transmission gear 46 to rotate, so that the transmission gear 46 rotates and meshes to drive the driven gear 47 to rotate. By setting the transmission gear 46 and the driven gear 47 to cooperate with each other, the rotating shaft 42 can be more stably clamped and limited for self-locking, increasing the structural stability of the equipment.

[0036] Specifically, a mounting plate 44 is fixedly connected to the outside of the mounting seat 41. The speed regulating motor 45 is fixedly installed on the top of the mounting plate 44, and the speed regulating motor 45 and the mounting plate 44 are bolt-fixed. The number of bolts is four. By fixing the speed regulating motor 45 in a detachable manner with bolts, it is convenient to repair and maintain the speed regulating motor 45. The speed regulating motor 45 and the controller 2 are electrically connected.

[0037] It should be noted that a transmission gear 46 is fixedly connected to the output shaft of the speed regulating motor 45, and the transmission gear 46 is meshed with a driven gear 47. The speed regulating motor 45 is electrically connected to the controller 2. When the speed regulating motor 45 is activated by the controller 2, the transmission gear 46 rotates, causing the transmission gear 46 to rotate and mesh with the driven gear 47, the rotating shaft 42, and the rotating base 43 to adjust the rotation angle.

[0038] In addition, the handle 3 is composed of a fixing frame and a grip rod, the grip rod is fixedly connected to the inside of the fixing frame, and the outside of the grip rod is sleeved with anti-skid rubber. By sleeved with anti-skid rubber on the outside of the grip rod, the comfort and anti-skid effect of the handle 3 when held are improved.

The servo motor 52 is activated by the controller 2 to drive the threaded rod 53 to rotate forward and reverse. The forward and reverse rotation of the threaded rod 53 causes the movable sleeve 54 to move the handle 3 upward or downward, facilitating adjustment according to the operator's needs and improving operational comfort and adaptability.

[0040] Among them, the adjustment mechanism 5 includes a mounting cylinder 51 fixedly connected to the top of the rotating seat 43, a servo motor 52 fixedly installed on the inner bottom wall of the mounting cylinder 51, a threaded rod 53 fixedly connected to the output shaft of the servo motor 52, and a movable sleeve 54 threadedly connected to the outside of the threaded rod 53 and extending to the outside of the mounting cylinder 51.

[0041] Specifically, the interior of the mounting cylinder 51 is provided with a movable opening adapted to fit the movable sleeve 54. The movable sleeve 54 is slidably connected to the interior of the movable opening. The end of the movable sleeve 54 away from the threaded rod 53 is fixedly connected to the bottom of the handle 3. The outer diameter of the movable sleeve 54 is adapted to the inner diameter of the mounting cylinder 61.

A chute adapted for the movable sleeve 54 is provided within the mounting tube 51, and the movable sleeve 54 and the mounting tube 51 are slidably connected. The provision of the movable sleeve 54 and the chute improves the stability of the handle 3 after adjustment, preventing displacement of the compactor body 1 during operation. The provision of the movable sleeve 54 effectively prevents the movable sleeve 54 from being removed from the inner wall of the mounting tube 51, effectively preventing the handle 3 and movable sleeve 5 from falling due to vibration during operation of the compactor body 1.

[0043] The working principle of the above embodiment is:

The rotating seat 43 drives the handle 3 to adjust the tilt angle through the adjustment mechanism 5 to adapt to the operating habits and construction conditions of different operators; when adjusting the length of the handle 3, the servo motor 52 is started by the controller 2 to drive the threaded rod 53 to rotate forward and backward. The threaded rod 53 rotates forward and backward so that the movable sleeve 54 drives the handle 3 to adjust upward or downward, which can be adjusted according to the needs of the operator. By setting the limit slider 6 and the slide groove, the stability of the handle 3 after adjustment is improved, and the rammer body 1 is prevented from offsetting when working. 3 is stored, by providing an angle adjustment mechanism 4, the handle 3 can be adjusted in angle, and the angle adjustment mechanism 4 can give the handle 3 a rotational force. When the device is not in use, the handle 3 can be driven to rotate so that the handle 3 is level with the ground, reducing the space used by the device to facilitate the placement of the device. By providing a limit slider 6, the movable sleeve 54 can be effectively prevented from being removed from the inner wall of the mounting tube 51, and the handle 3 and the movable sleeve 5 can be effectively prevented from falling due to vibration when the rammer body 1 is working. The speed regulating motor 45 is started by the controller 2 to drive the transmission gear 46 to rotate, so that the transmission gear 46 rotates and engages to drive the driven gear 47 to rotate. By providing the transmission gear 46 and the driven gear 47 for use in conjunction with each other, the rotating shaft 42 can be more stably engaged and self-locked.
