Special spray head for lubrication of joint of deck beam and jaw plate of grab bucket

Abstract

The invention relates to a special spray head for lubrication of a joint of a deck beam and a jaw plate of a grab bucket. The special spray head comprises an outer cover, a partition board, spray nozzles, connection pipes, filter nets, an end cap, an air inlet and an oil inlet, wherein the partition board is located at the joint of the upper end and the lower end of the outer cover; the spray nozzles are located on the bottom end surface of the partition board; mounting external threads are arranged at upper ends of the spray nozzles, and the spray nozzles are uniformly mounted at lower ends of round step-shaped threaded holes in the partition board; the connection pipes are located on the top end surface of the partition board and uniformly mounted at upper ends of the round step-shaped threaded holes in the partition board; top ends of the connection pipes are sleeved with the filter nets in a wound manner; the end cap is located right above the outer cover; the air inlet and the oil inlet penetrate through the end cap respectively and are fixedly connected with the end cap respectively. Components of the special spray head are connected through threads and can be conveniently assembled and disassembled, the special spray head can be completely matched with the joint of the deck beam and the jaw plate of the grab bucket, the situation that lubrication oil is split and wasted is avoided, lubrication operation is simple and convenient, and the lubrication efficiency is high.

Description

technical field [0001] The invention relates to the field of auxiliary accessories of grab lubricating equipment, in particular to a special nozzle for lubricating the joint between the upper bolster and the jaw plate of the grab.
