[0002] Existing pile drivers for small excavators include a gear box body, a high-frequency vibration driving mechanism, a fixed tooth seat and a moving tooth seat. Among them, the high-frequency vibration driving mechanism is arranged on the gear box body and used to drive the gear box body to vibrate at a high frequency. The two constitute a gear box that can generate vibration. The fixed tooth seat and the moving tooth seat are relatively arranged at the bottom of the gear box body and are respectively fixedly connected to the bottom of the gear box body by screws. When in use, the pile material can be fixed between the fixed tooth seat and the moving tooth seat, and then the high-frequency vibration driving mechanism is used to drive the gear box body to vibrate at a high frequency. At this time, the gear box body will drive the pile material to vibrate at a high frequency, so as to complete the work of driving piles into the ground through the vibration of the pile material.

[0003] However, when the existing pile driver for a small excavator is in use, when it is necessary to fix different pile types, it is necessary to manually adjust the moving tooth seat to meet the fixation of different pile types. This not only has cumbersome operation, reduces work efficiency, but also has poor applicability due to the limitation of adjustment accuracy. Summary of the Invention

Among them, a fixed tooth plate is arranged on the side of the fixed tooth seat facing the moving tooth seat; a horizontally arranged oil cylinder is arranged on the moving tooth seat. The telescopic rod of the oil cylinder faces the fixed tooth plate, and the end of the telescopic rod is fixedly provided with a moving tooth plate that is arranged opposite to the fixed tooth plate and is used to approach and move away from the fixed tooth plate under the drive of the oil cylinder to cooperate with the fixed tooth plate to clamp different pile types.

[0007] Preferably, a through hole for passing through the oil cylinder is opened on the moving tooth seat, and the oil cylinder is installed in the through hole of the moving tooth seat by bolts.

[0008] Preferably, two longitudinally arranged arc-shaped oil cylinder fixing plates with opposite arc openings are arranged on the side of the moving tooth seat away from the moving tooth plate by bolts.

[0009] Preferably, the fixed tooth seat and the movable tooth seat are respectively fixed to the bottom of the gearbox by bolts, and the fixed tooth plate is fixed to the fixed tooth seat by bolts.

[0010] Preferably, a backing plate is arranged between the tops of the fixed tooth seat and the movable tooth seat, is located between the oil cylinder and the gearbox, and is fixedly connected to the bottom of the gearbox by bolts.

[0011] Due to the adoption of the above technical solutions, the technical progress achieved by the present utility model is as follows.

[0012] By arranging the oil cylinder in the present utility model to drive the movable tooth plate to approach and move away from the fixed tooth plate, the distance between the movable tooth plate and the fixed tooth plate can be changed, and thus the clamping of different pile types can be realized. It not only has simple operation and improves work efficiency, but also has high adjustment accuracy and strong applicability. BRIEF DESCRIPTION OF THE DRAWINGS
