A rake pusher and its pusher device assembly

Abstract

The invention discloses a pushing and raking device assembly of a pushing and raking machine. The pushing and raking device assembly of the pushing and raking machine comprises a pushing and raking shovel, an H-shaped shovel frame, a lift cylinder used for lifting the H-shaped shovel frame, and an angle adjustment mechanism used for adjusting the angle of the pushing and raking shovel, and further comprises a base installed on a rear axle box of the pushing and raking machine, wherein two hinge joint lugs which upwards extend from the base, and are used for installing the H-shaped shovel frame are arranged on the base, the other end of each of two longitudinal beams of the H-shaped shovel frame is hinged to the corresponding hinge joint lug, the lift cylinder is arranged at the lower end of the H-shaped shovel frame, one end of the lift cylinder is hinged to the middle of the H-shaped shovel frame, and the other end of the lift cylinder is hinged to the base. Due to the fact that the lifting height of the pushing and raking shovel can be effectively increased through the pushing and raking device assembly, the mode that coal piles with the large height or materials with the large height are cleaned in an impact mode at present is changed, damage to parts of the pushing and raking machine is avoided, and the maintenance cost of the pushing and raking machine is reduced. The invention further provides the pushing and raking machine with the pushing and raking device assembly.

Description

technical field [0001] The invention relates to the technical field of heavy machinery equipment, and more specifically, relates to a rake pushing machine and a raking device assembly thereof. Background technique [0002] The rake pusher is widely used in the clearing and liquidation of bulk cargo in the port, and it can also be used for the rake push of loose materials in power plants and wharves. When the pusher works in a power plant or a cabin, its working environment is very harsh. [0003] The raking device assembly of the raking machine mainly includes: raking shovel, H-shaped shovel frame for supporting the raking shovel, lifting cylinder for lifting the H-shaped shovel frame, and angle adjustment mechanism for adjusting the angle of the raking shovel , wherein the H-shaped shovel frame includes two parallel longitudinal beams and a cross beam for connecting the two longitudinal beams as a whole. At present, the installation form of the push-rake device assembly i...

Problems solved by technology

[0005] Since one end of the H-shaped shovel is hinged on the trunnion of the trolley outside the track, that is, one end of the H-shaped shovel is close to the ground, the lifting height of the rake shovel is limited, generally only about 1.5 meters, but this is necessary for long-term accumulation. For the relatively thick and high-height coal pile or material, the operator can only hit the whole material through the pusher device assembly, so that the higher material falls and then pushes the rake to close the warehouse; often during the impact process The oil cylinder and the trunnion connected to the oil cylinder are seriously damaged, and the hinge shaft between the H-type shovel frame and the lifting cylinder is often deformed due to impact, which will seriously aggravate the wear of the hinge shaft, resulting in the maintenance of the entire rake machine. Large and expensive to maintain
