The joint of the rear end of the bucket tooth of each rear bucket tooth and the bottom surface of the bottom plate of the wrapper sheet is formed by welding three triangular steel plates with the thickness of 1.6cm, and the circumferential spacing of the triangular steel plates is 120 degrees.

Two through holes with the diameter of 10.8cm are arranged on the bottom plate of the wrapper sheet and at the position 30cm away from the front end of the bucket, and the rear ends of the rear bucket teeth penetrate through the through holes and are fixed on the bottom plate of the wrapper sheet.

The ear plate is formed by double-splicing welding of two steel plates with the thickness of 1.6 cm.

Compared with the prior art, the utility model has the following beneficial effects:

1. the utility model can fully excavate the operation blind area of the traditional bucket tooth at the junction of the steps due to the longer rear bucket tooth, not only can effectively control the over-excavation, but also reduces the manual operation intensity, greatly reduces the manual excavation workload, is safe to construct, solves the problem that the traditional excavator has the problem that the visual blind area over-excavation is difficult to control when the traditional carbonaceous slate tunnel is excavated, avoids the problems of increasing the investment of manpower and material resources, affecting the progress, increasing the cost and the like after the over-excavation occurs, greatly saves the labor, and improves the working efficiency.

2. The utility model has simple manufacture, wide material sources and strong operability.
