Embodiment 1

[0017] Such as figure 1 As shown, a double-drilling arm-type breaker includes a base 1, a reciprocating hammer 2, a drill bit 3, a drill bit 2 4, an oil cylinder 5, a reversing valve 6, a pump source 7, an accumulator 8, The oil tank 9, the reciprocating hammer 2 is hinged on the base 1, the drill bit 3 and the drill bit 2 4 are respectively installed on the base 1, the drill bit 3 and the drill bit 2 4 are drill bits for breaking rocks with the same structure , Drill bit 1 3 and drill bit 2 4 form an included angle, the included angle is 15︒~30︒, the setting of the included angle can realize centralized crushing at the same point. The tail of the oil cylinder 5 is fixedly installed on the base 1, and a linkage device is provided between the oil cylinder 5 and the reciprocating hammer 2. The linkage device is that the movable rod of the oil cylinder 5 drives the straight grooved rod 10 provided at the front end of the movable rod to move, driving the reciprocating hammer 2. T...

Embodiment 2

[0023] On the basis of embodiment 1, embodiment 2 changes the linkage device. In Embodiment 2, the tail of the oil cylinder 5 is hinged on the base 1, and the front end of the movable rod of the oil cylinder 5 is hinged with the round rod provided on the cantilever of the reciprocating hammer 2. The movable rod of the oil cylinder 5 drives the straight grooved rod 10 arranged at the front end of the movable rod to move, and the straight grooved rod 10 is hinged with the round rod provided on the cantilever of the reciprocating hammer 2, thereby driving the reciprocating hammer 2 to reciprocate and rotate to hit the drill bit 1 3 and the drill bit 2 4 .

[0024] The working principle of embodiment 2 is as follows:

[0025] The reversing valve 6 is switched to the upper position, the high-pressure oil from the pump source 7 enters the rod cavity of the oil cylinder 5, and the movable rod of the oil cylinder 5 is pushed to retract. 2 Rotate counterclockwise; when the reciprocat...

Embodiment 3

[0027] On the basis of embodiment 1, embodiment 3 changes the linkage device. In Embodiment 3, a rack 11 is provided at the front end of the movable rod of the oil cylinder 5 , and a gear 12 is provided at the hinge joint between the reciprocating hammer 2 and the base 1 , and the rack 11 and the gear 12 are engaged and connected. The movable rod of the oil cylinder 5 drives the rack 11 provided at the front end of the movable rod to move, the rack 11 moves to drive the gear 12 to rotate, and the gear 12 is relatively fixed to the reciprocating hammer 2, thereby driving the reciprocating hammer 2 to reciprocate and hit the drill bit 1 3 and the drill bit 2 4.

[0028] The working principle of embodiment 3 is as follows:

[0029] The reversing valve 6 is switched to the upper position, the high-pressure oil from the pump source 7 enters the rodless cavity of the oil cylinder 5, and the movable rod of the oil cylinder 5 is pushed out, the rack 11 provided at the front end of th...

Abstract

The invention provides a double-drill-bit swing arm type breaking hammer. The double-drill-bit swing arm type breaking hammer comprises a base, a swing hammer, a drill bit I, a drill bit II, an oil cylinder, a reversing valve, a pump source, an energy accumulator and an oil tank. The swing hammer is hinged to the base. The drill bit I and the drill bit II are mounted on the base. An included angleis formed between the drill bit I and the drill bit II. A linkage device is arranged between the oil tank and the swing hammer. The linkage device drives the swing hammer to beat the drill bit I andthe drill bit II in a reciprocating mode. An oil inlet of the oil tank is connected with ports A and B of the reversing valve. A port B of the reversing valve is connected with the pump source and theenergy accumulator. A port T of the reversing valve is connected with the oil tank. The double-drill-bit swing arm type breaking hammer has the advantages of having the good centralized crushing effect, improving the crushing efficiency and utilizing rebound energy of impact each time to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of hydraulic breakers, in particular to a double-drill-head boom-type breaker used for breaking shallow rocks. Background technique [0002] The usual hydraulic breaker adopts a combined structure of a single drill bit and a hydraulic impactor. The rebound energy generated after the hydraulic impactor strikes a single drill bit cannot be effectively utilized, and is usually absorbed by the hydraulic system, and most of it is converted into heat energy and dissipated. Therefore, the crushing effect and crushing efficiency of the single-point impact of a single drill bit on the rock are relatively low. Contents of the invention [0003] The object of the present invention is to provide a double-drill jib-arm type breaker that concentrates the crushing effect, improves the crushing efficiency, and maximizes the use of the rebound energy of each impact. [0004] In order to achieve the above object, the pres...
