LOCKING MECHANISM WITH ELECTRIC DRIVE FOR EARTHMOVING EQUIPMENT AND IMPLEMENTATION METHOD Russian patent published in 2021 - IPC E02F9/28 E02F9/00 E02F3/04 

FIELD: earthmoving equipment.

SUBSTANCE: group of inventions relates to earthmoving equipment for excavating soil, tillage, loosening, loading and/or developing soil. A bucket for earthmoving equipment with a bucket cutting edge and several teeth of an earthmoving tool, removable attached to the cutting edge, contains: several tooth holders on the bucket cutting edge, several teeth, removable attached to corresponding tooth holders, a recess for accommodating a locking mechanism in each tooth holder, locking mechanisms with an electric drive for the tooth, placed in corresponding recesses for accommodating the locking mechanism, a groove for accommodating the locking mechanism in the inner cavity of each tooth, coinciding with the recess for accommodating the locking mechanism, and a remote control device. Each of the teeth forms the inner cavity suitable for pushing on corresponding tooth holders. Locking mechanisms with the electric drive for the tooth include a movable element of the locking mechanism and the electric drive capable of moving the element of the locking mechanism between two positions in response to a separate encoded signal. The remote control device is made with the possibility to send corresponding encoded signals to corresponding electric drives to activate the corresponding electric drive in the corresponding locking mechanism with the electric drive for the tooth.

EFFECT: ease of replacing teeth on earthmoving equipment, protecting the locking mechanism from abrasion, ensuring a quick response of the locking mechanism to commands of the remote control device located outside the tooth and the adapter.
