Multiple groups of rectangular grooves with the same interval are opened at the front ends of the upper and lower sides of the tooth seat plate. The inner part of the rectangular groove is symmetrically connected with limiting protrusions on the left and right. Multiple groups of connecting bottom plates are fixed at the rear side of the top of the tooth seat plate. A fixed cross bar is installed at the rear side of the top of the connecting bottom plate. One end of the fixed cross bar is installed with a positive and negative motor. The output end of the positive and negative motor penetrates the inside of the fixed cross bar and is connected with a bidirectional screw rod. The outer side of the bidirectional screw rod is symmetrically thread sleeved with screw rod sliding sleeves. The left and right sides of the top of the connecting bottom plate are both slidably connected with installation clamping plates. The front ends of the opposite sides of the two installation clamping plates are both fixed with connecting insertion rods. An inner groove is opened inward at the rear side of the shovel teeth. The top surface and the bottom surface of the inner groove are both provided with limiting slots inserted and pulled cooperatively with the limiting protrusions. Connecting jacks are opened on the left and right sides of the shovel teeth.

[0008] As a preferred scheme of the utility model, multiple groups of shovel teeth are provided and are horizontally arranged and distributed on the tooth seat plate. The tooth seat plate and the shovel teeth are designed as a detachable structure.

[0009] As a preferred solution of the present utility model, a controller is provided on the outer side of the bucket, and the controller is connected to the forward and reverse motor through a wire, and the connection method is electrical connection.

[0010] As a preferred solution of the present utility model, both ends of the bidirectional screw are rotatably connected inside the fixed cross bar through bearing seats, and the bidirectional screw is formed by splicing two screws with opposite threads.

[0011] As a preferred solution of the present utility model, a waist-shaped sliding groove is provided inside the installation clamping plate, and sliding rods slidingly connected to the waist-shaped sliding groove are provided on both the left and right sides of the top of the connection bottom plate, and the screw sliding sleeve is fixedly connected to the installation clamping plate.

[0012] As a preferred solution of the present utility model, the connection method between the connection insertion rod and the connection jack is plug-in connection.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] In the present utility model, by providing a tooth seat that facilitates the loading and unloading of the shovel teeth, the shovel teeth can be quickly replaced without bolts, which not only facilitates operation but also avoids the problem that the bolts are easily rusted due to being directly exposed to the outside after fixing the shovel teeth, resulting in difficulty in replacing the shovel teeth.
