Abstract

The invention discloses a bionic excavator bucket tooth, which is composed of a mounting end and a soil touch end, wherein the soil touch end is arranged at the front part of the mounting end; the mounting end is provided with an upper end surface, a lower end surface and a concave cavity; the soil touch end is provided with an inner-side soil touch surface, an outer-side soil touch surface and a front-end soil touch surface; the front-end soil touch surface is an arc curved surface; the radius of the arc is 3-8mm; the inner-side soil touch surface and the outer-side soil touch surface are oppositely arranged; the head end in a profile curve of the inner-side soil touch surface is tangent to the arc upper end of the front-end soil touch surface; the tail end in the profile curve of the inner-side soil touch surface is tangent to the upper end surface of the mounting end; the head end in the profile curve of the outer-side soil touch surface is tangent to the arc lower end of the front-end soil touch surface; the tail end in the profile curve of the outer-side soil touch surface is tangent to the lower end surface of the mounting end. Experimental results show that the penetrating force of the tooth is effectively reduced; the abrasion on the tip part of the bucket tooth is relieved; the service life is prolonged; the energy-saving target is also achieved.

Description

technical field [0001] The invention relates to an excavating tool, in particular to a bucket tooth of a bionic excavator. Background technique [0002] An excavator, also known as an excavator, is an earth-moving machine that uses a bucket to excavate materials that are higher or lower than the bearing surface, and load them into transport vehicles or unload them to the stockyard. The bucket is the main energy-consuming part of the excavator in the working process. The teeth are located at the end of the excavator bucket and are its main soil-contacting parts. When working, the bucket teeth wedge into the soil at a certain angle, destroying the soil interface layer, so that the bucket enters the soil with less resistance. The performance of the bucket teeth directly affects the excavation performance of the excavator bucket and even the excavator. Reducing the soil cutting resistance of the bucket teeth can effectively improve the excavation efficiency of the excavator. ...
