The harrow body comprises harrow teeth, which are evenly spaced and parallel. The tail of the harrow tooth is provided with a clamping groove, and the clamping grooves between the tails of the harrow teeth are provided with bucket tooth seat clamping plates. The middle part of the harrow tooth is provided with a bucket tooth clamping plate. The harrow teeth are spaced apart, and a thread seat is provided between them. Two symmetrically arranged screw holes are formed in the thread seat. The harrow body is connected to the outside of the bucket tooth. A light hole is formed in the pressing plate. The mounting bolts are arranged on the inside of the light hole. The gasket is arranged between the outside of the mounting bolts and the pressing plate. The tail of the mounting bolt is threadedly connected with the screw hole.

[0007] Further, the middle part of the upper and lower end faces of the bucket tooth is provided with a protruding structure.

[0008] Further, the protruding structure is clamped and limited by the bucket tooth clamping plate.

[0009] Further, the end face of the pressing plate is provided with a plate tooth, which is arranged between the adjacent light holes.

[0010] Further, the end of the plate tooth is provided with an inclined surface, which is fitted with the end face of the bucket tooth.

[0011] Further, the end face of the tooth holder card board in contact with the tooth holder is provided with an anti-skid layer.

[0012] Further, the end of the mounting bolt is externally threaded with a nut.

[0013] The device has the following beneficial effects:

[0014] 1. The implement rake is designed as a split structure with the bucket, and is installed or disassembled through the cooperation of the bolt and the limiting structure, is convenient and fast, can be applied to the bucket with the rake, avoids the purchase of the additional bucket with the rake, realizes the quick switching of the bucket and the implement rake, reduces the use cost, and improves the working efficiency.
