Abstract

The invention relates to the technical field of work machines, in particular to a butt joint device. The butt joint device comprises a first connector and at least one second connector. Each of the first connector and the second connectors correspondingly communicates with a work oil way. The first work oil way corresponding to the first connector communicates with an oil tank, and the second workoil ways corresponding to all the second connectors communicate with an oil discharging work oil way through an oil discharging oil way. The oil discharging oil way is provided with a control valve set so as to control circulation of hydraulic oil on the oil discharging oil way. When an accessory tool fast connector is in butt joint with the second connector, a core body of the accessory tool fast connector can push hydraulic oil in the second connectors to be discharged into an oil tank through the oil discharging oil way and the first work oil way, connector butt joint can be completed without loosening a fast change connector, and the technical problems that when a fast connector on an overall machine in the prior art is in butt joint with a fast connector on an accessory tool, connector butt joint can be successfully achieved only by loosening of the fast change connector, operation is troublesome, connector damage is possibly caused after multiple times of loosening are solved.

Description

technical field [0001] The invention relates to the technical field of working machinery, in particular to a docking device. Background technique [0002] As a kind of construction machinery with multiple attachments, the skid steer loader is characterized in that a complete machine can be equipped with hundreds of attachments, which greatly broadens the application range of the skid steer loader. However, since different attachments need to be replaced when using different attachments, generally the whole machine is equipped with quick connections, which can facilitate the replacement of various attachments and improve work efficiency. [0003] When replacing attachments, since the quick connector on the complete machine is connected to the reversing valve, when the quick connector on the attachment is connected to the quick connector on the complete machine, the middle spool of the reversing valve connects the quick change connector to the reversing valve. The oil between...
