Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery plowshares and relates to a plowshare with wing-shaped tooth heads used on agricultural machinery. Background Art

[0002] Agricultural machinery refers to a general term for various mechanical equipment used in agricultural production. A plowshare can be installed on the agricultural machinery for operation. The plowshare installed on the existing agricultural machinery is generally made of pure hardened steel, and the plowshare generally directly contacts the soil and loosens the topsoil. Although most of the soil is soft soil, some hard soil and gravel are mixed in the soft soil. Since the working surface of the existing plowshare has no protective structure, it is easy to cause damage and deformation due to long-term use and collision with the hard soil and gravel in the soil. In addition, vibration will be generated when the plowshare is operating, resulting in loose connection between the plowshare and the agricultural machinery and loose connection bolts at the bolt holes, affecting the normal use of the plowshare. In addition, there is generally accumulated water in the soil, resulting in a certain viscosity of the soil. When the plowshare is working, the soil will adhere to the surface of the plowshare, affecting the normal operation to a certain extent. If it is not cleaned for a long time, it will also cause corrosion to the surface of the plowshare, affecting its service life. For this reason, a plowshare with a wing-shaped tooth head for use on agricultural machinery is designed to overcome the above problems. Utility Model Content
