Problems solved by technology

[0002] So far, the three-tooth harrow is mostly composed of a wooden handle tightly inserted into the mounting hole of the metal three-tooth harrow head. At present, the wooden handle of the three-tooth harrow is mostly directly rigidly inserted into the three-tooth harrow In the installation hole of the rake head, if so, there is no flexibility between the connection between the rake head and the rake handle. There is often a problem that the tiger's mouth of the user's hand is shattered, so it is easy to cause passive use

Abstract

The invention provides a dual-purpose elastic three-tooth-rake rake structure. Three-tooth-rake teeth and rake teeth are connected to a three-tooth-rake head body in an up-down mode. A rake handle is arranged in the middle of the three-tooth-rake head body. A strength disc-shaped spring is connected to the rake handle. The top end of the strength disc-shaped spring is connected with a handle. The dual-purpose elastic three-tooth-rake rake structure has the advantages of being simple in structure, small in shaking force, good in flexibility, durable in use, good in digging effect and thus capable of bringing convenience to people in use.

Description

technical field [0001] The invention relates to a three-toothed rake structure, in particular to a dual-purpose elastic three-toothed rake structure, which belongs to the technical field of agricultural tools. Background technique [0002] So far, the three-tooth harrow is mostly composed of a wooden handle tightly inserted into the mounting hole of the metal three-tooth harrow head. At present, the wooden handle of the three-tooth harrow is mostly directly rigidly inserted into the three-tooth harrow In the installation hole of the rake head, if so, there is no flexibility between the connection between the rake head and the rake handle. There is often the problem that the mouth of the user's hand is broken by the shock, which easily leads to passive use. Contents of the invention [0003] The object of the present invention is to provide a dual-purpose elastic three-toothed rake structure with simple structure, small vibration force, good flexibility, durability, and go...
