Abstract: The article presents the design of the backhoe implement. The relevance of construction in the field of economic development is given. The article shows ways to reduce construction costs. One of the ways to reduce construction costs is to increase the performance of construction machines, in particular hydraulic backhoes. The methods for increasing the productivity of hydraulic backhoes are given. The design of the existing implement of the backhoe is considered and the pressure on the bucket arising during the digging process is analyzed. The study presents the ways to reduce the resistance pressure to digging on the excavator bucket. One way to reduce the resistance pressures to digging arising on the excavator bucket is to change the shape of the structural elements of the bucket and the trajectory of their movement. The shape and the trajectory of the inner wall of the bucket are given to reduce the resistance pressure to digging. The design is proposed and the principle of a hydraulic backhoe operation that experiences less resistance when digging is described. The study shows due to which improvements the performance of hydraulic backhoes having a new design bucket is increased.

Key words: excavator bucket pressure soil digging resistance performance design construction
