A driven pulley 51 is rotatably arranged on the right side of the bottom of the bottom plate 1. The driving pulley 51 is connected to the left end of the belt 53, and the driven pulley 51 is connected to the right end of the belt 53. A through hole is opened on the top of the driven pulley 51 for the drill bit 710 to pass through.

[0053] The top of the driven pulley 51 is fixedly connected to the bottom of the rotating cover 54 , the outer surface of the rotating cover 54 is threadedly connected to the inner surface of the telescopic cover 55 , and a fixed cover 56 is fixedly provided on the right side of the top of the bottom plate 1 .

[0054] First key slots 57 are provided on the left and right sides of the inner wall of the fixed cover 56, and first shaft keys 58 are fixedly provided on the left and right sides of the outer surface of the telescopic cover 55, and the first shaft keys 58 are slidably provided in the first key slots 57. The first shaft keys 58 can cooperate with the first key slots 57 to limit the rotation of the telescopic cover 55.

[0055] The working principle of a safe and efficient construction site pile driver based on Example 1 is:

At this time, the controller 9 is used to drive the first motor 4 to work, and the first motor 4 is started to drive the screw 5 to rotate, and the screw 5 rotates to drive the moving block 7 to move downward;

[0057] Second, when the moving block 7 moves downward, the screw rod 5 rotates to drive the driving pulley 51 to rotate, the driving pulley 51 rotates to drive the driven pulley 51 to rotate by the belt 53, the driven pulley 51 rotates to drive the rotating cover 54 to rotate, and the rotating cover 54 rotates to drive the telescopic cover 55 to move downward by the thread on the outer surface of the rotating cover 54;

[0058] Third, when the telescopic cover 55 moves downward, the first keyway 57 and the first shaft key 58 cooperate to limit the rotation of the telescopic cover 55 to prevent the telescopic cover 55 from being driven by the rotating cover 54 to rotate. On the contrary, the first motor 4 reverses to drive the screw 5 to reverse, thereby driving the moving block 7 to move upward and the telescopic cover 55 moves upward at the same time. The advantage of this is that the telescopic cover 55 can move up and down with the drill bit 710, thereby reducing the material thrown out by the centrifugal force of the drill bit 710 during the ascent and descent process of the drill bit 710, thereby reducing the splash of the drill bit 710 when it rotates. The damage to the surrounding personnel caused by the splash.

[0059] Embodiment 2:

[0061] A second motor 71 is fixedly arranged on the right side of the top of the moving block 7. The output end of the second motor 71 passes through the top of the moving block 7 and is fixedly connected to the upper end of the first rotating shaft 72. The lower end of the first rotating shaft 72 is fixedly connected to the center of the top of the first limit block 73.

[0062] The center of the bottom of the first limit block 73 is fixedly connected to the upper end of the second rotating shaft 74 . Second shaft keys 75 are fixedly provided on the left and right sides of the outer surface of the second rotating shaft 74 . A rotating sleeve 76 is slidably provided on the lower end of the second rotating shaft 74 .

[0063] Second key slots 77 are provided on the left and right sides of the inner surface of the top of the rotating sleeve 76, and the second shaft key 75 is slidably set in the second key slots 77. The second key slots 77 can cooperate with the second shaft key 75 so that the rotating sleeve 76 can rotate and slide up and down at the same time. A spring 78 is wound around the second rotating shaft 74, and the bottom of the first limit block 73 is fixedly connected to the upper end of the spring 78, the top of the rotating sleeve 76 is fixedly connected to the lower end of the spring 78, and a second limit block 79 is fixedly set at the lower end of the second rotating shaft 74, and the second limit block 79 is slidably set inside the rotating sleeve 76, and the bottom of the rotating sleeve 76 is fixedly connected to the top of the drill bit 710.

[0064] The working principle of this embodiment is:

[0065] First, when the moving block 7 moves downward, the controller 9 is used to drive the second motor 71 to work, and the second motor 71 drives the first rotating shaft 72 to rotate, thereby driving the first limit block 73, the second rotating shaft 74 and the second shaft key 75 to rotate, and the second shaft key 75 rotates to cooperate with the second key slot 77 of the rotating sleeve 76 to drive the rotating sleeve 76 to rotate;

[0066] Second, the rotating sleeve 76 rotates to drive the drill bit 710 to rotate. After the drill bit 710 rotates, it and the moving block 7 are driven downward by the screw 5 to drive the rotating drill bit 710 downward to drive piles. In the process of the drill bit 710 moving downward to drive piles, it may encounter relatively hard stones to impact the drill bit 710;

[0067] Third, at this time, the stone creates an impact force on the drill bit 710, pushing the drill bit 710 to move upward. The upward movement of the drill bit 710 drives the rotating sleeve 76 to move upward. During this process, the rotating sleeve 76 squeezes the spring 78 to deform the spring 78. The deformation of the spring 78 generates a force opposite to the rotating sleeve 76, so that the impact force of the stone can offset the deformation force of the spring 78, cushion the drill bit, and reduce the problem of the drill bit 710 being damaged when encountering hard materials.

[0068] The utility model provides a safe and efficient pile driver for construction sites through improvement, wherein a screw rod 5 is provided, and a drill bit 710 is driven by the screw rod 5 to move up and down for pile driving. At the same time, a transmission pulley 51 is used to drive a telescopic cover 55 to follow the drill bit 710 to move up and down, thereby reducing the material thrown out by the centrifugal force when the drill bit 710 rotates during the rising and falling process of the drill bit 710, thereby blocking the splashing of the drill bit 710 when it rotates and causing harm to surrounding personnel; at the same time, a spring 78 is provided, and the deformation of the spring 78 is used to generate a force opposite to the rotating sleeve 76, so that the impact force of the stone can be offset by the deformation force of the spring 78, so as to buffer the drill bit and reduce the problem that the drill bit 710 will be damaged when encountering hard materials.
