specific Embodiment 1

[0025] figure 1 It shows a hook digger rock jib forearm with a pressure sharing wing, which includes a boom connection mechanism 1 and a hook digging plate mechanism 2, and the boom connection mechanism 1 includes two splints 11 arranged in parallel in the vertical direction The upper part of the hook-digging plate mechanism 2 is a connecting part 21, which is inserted between the two splints 11, and the connecting part 21 is connected to the two splints 11 in a detachable manner. Both sides of the middle part of the hook-digging plate mechanism 2 There are pressure sharing wings 22 deployed to both sides. The top of the pressure sharing wings 22 is in contact with the bottom of the splint 11. The outer surface of the pressure sharing wings 22 is inclined, and the direction of the inclination is gradually toward the hook digging mechanism 2 from top to bottom. Slope in the middle.

[0026] The upper part of the digging hook plate mechanism is set relatively thin, so that the ...

specific Embodiment 2

[0027] This embodiment is a further description of the boom connection mechanism 1 on the basis of the specific embodiment 1. The upper part of the rear end of the boom connection mechanism 1 is provided with a forearm oil cylinder rod head seat 3, and the lower parts of the two splints 11 are The large and small arm connecting through holes 4 are arranged at the same position, and the large and small arm connecting through holes 4 are located near the rear end of the boom connecting mechanism 1 .

[0028] The connecting mechanism of the boom is connected with the boom through the connecting through hole of the big and small arms, and the rod head seat of the forearm cylinder is used to connect with the oil cylinder at the upper end of the boom. Oil cylinder to adjust the angle of the forearm.

specific Embodiment 3

[0029] This embodiment is based on the specific embodiment 1 to further illustrate the splint 11. The inside of the splint 11 is provided with a hollow cavity, and the surface of the splint 11 is provided with a filling material inlet 5 and a hollow cavity. The filler outlet 6 is arranged obliquely at the bottom of the hollow inner cavity, and the lowest point of the bottom of the hollow inner cavity is connected with the filler outlet 6 .

[0030] A hollow inner cavity is set inside the splint, and weight-increasing materials can be filled from the filling material inlet to the hollow inner cavity, which can increase the overall weight of the forearm of the rock arm of the digging hook, and the overall weight of the forearm of the rock arm of the digging hook The increase can make the rock-breaking effect better. When the forearm does not need such a heavy weight, open the filling material outlet, and the filling material in the hollow cavity will flow out from the filling mat...

Abstract

The invention discloses a digging hook rock arm small arm with pressure sharing wings. The digging hook rock arm small arm comprises a large arm connection mechanism and a digging hook plate mechanism. The large arm connection mechanism comprises two clamping plates arranged in parallel in the vertical direction. The upper portion of the digging hook plate mechanism is a connection portion, the connection portion is inserted between the two clamping plates, the connection portion is detachably connected with the two clamping plates, the two sides of the middle of the digging hook plate mechanism are provided with the pressure sharing wings unfolded towards the two sides, the tops of the pressure sharing wings make contact with the bottoms of the clamping plates, and the outer side faces ofthe pressure sharing wings are gradually inclined from top to bottom towards the middle of the digging hook mechanism. The problem that digging hook clamping plates of an existing clamping piece typedigging hook rock arm are likely to be damaged after bearing too large pressure due to the insufficient self height is solved.

Description

technical field [0001] The invention relates to the field of rock-breaking and digging hook machinery, in particular to a rock arm forearm of a digging hook with a pressure sharing wing. Background technique [0002] The hook digging rock arm is usually used for digging and digging and planing the rock. The digging hook rock arm is composed of a large and small arm and a digging hook. The large and small arms can play a role in controlling the action of the digging hook. The big arm is connected with the frame, and the arm length is longer, so it is commonly called the big arm, and the small arm is connected with the digging hook, and the arm is small, so it is commonly called the small arm. [0003] The forearm of existing digging hook rock arm is divided into two kinds, and a kind of is the forearm of fixed digging hook rock arm, and a kind of is the forearm of digging hook rock arm with oil cylinder structure, and the forearm of fixed digging hook rock arm is The struc...
