Description

Technical Field

[0001] The utility model relates to the technical field of breaker hammers, in particular to a hydraulic-gas combined breaker hammer with adjustable angle. Background Art

[0002] The operating principle of a hydraulic-pneumatic breaker relies primarily on the expansion of hydraulic oil and compressed nitrogen at the rear, which simultaneously push the piston. Its interior is divided into three main sections: the upper cylinder, the middle cylinder, and the lower cylinder. The upper cylinder stores low-pressure nitrogen, the middle cylinder houses the oil piston, reversing valve, accumulator, oil seal, and other components, while the lower cylinder secures the steel chisel, flat pin, cross pin, inner and outer bushings, and other components. The accumulator, filled with nitrogen, stores residual energy from the hydraulic breaker's previous strike and the energy from piston recoil, releasing this energy during the second strike, thereby increasing the hammer's impact power.

[0003] After long-term use, the bushing of the existing hydraulic breaker is easy to wear, which can easily lead to the failure of striking when the drill rod is pressed, but can strike when it is lifted a little. The bushing needs to be replaced. The traditional replacement method requires removing the splint and the entire cylinder structure, which is troublesome to repair and replace.

[0004] An existing patent (publication number: CN213805575U) discloses a washable, air-proof hydraulic breaker. The breaker comprises a hydraulic breaker body composed of two symmetrically arranged sets of clamping steel plates and a rectangular cylinder positioned between the plates. The sides of the rectangular cylinder mate with the inner walls of the two sets of clamping steel plates, respectively. The two sets of clamping steel plates are fixedly connected by bolts and nuts. One set of the clamping steel plates has a mounting slot at the bottom end of one side. The addition of a quick-release mechanism not only facilitates bushing replacement, but also saves labor, achieves quick release, and improves the striking efficiency of the drill rod.

[0005] In response to the above problems, the solution given in the existing patent is to achieve the quick-release effect by adding a quick-release structure to facilitate the replacement of the bushing. However, when the crushing drill rod is crushing, dust is easily generated. This dust is easy to adhere to the surface of the drill rod, causing dust to enter the inside of the drill rod when it is extended and retracted, affecting the use of the breaker hammer. Summary of the Invention

[0006] The purpose of the utility model is to provide a hydraulic-gas combined breaker hammer with adjustable angle. The spring will push the movable block to move, and then the movable rod will drive the mounting plate to move. At this time, the cleaning brush inside the mounting plate will better contact the outer surface of the drill rod, and then remove the dust and impurities adhered to the outer surface of the drill rod, effectively reducing the entry of dust and impurities into the interior of the breaker hammer, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: an angle-adjustable hydraulic-gas combined breaker hammer, comprising a breaker hammer housing, a driving member fixed inside the breaker hammer housing, a crushing mechanism for crushing objects provided at the lower end of the driving member, and an adjustment mechanism for adjusting the crushing angle fixed at the telescopic end of the driving member;

[0008] The crushing mechanism includes a protective shell, which is fixed to the lower end of the driving member. Mounting tubes are fixed on both sides of the protective shell. Springs are installed inside the two mounting tubes. The ends of the springs are abutted and connected with movable blocks. The end of the movable block is fixed with a movable rod that passes through the interior of the protective shell. The end of the movable rod is fixed with a mounting plate, and the inner wall of the mounting plate is fixed with a cleaning brush.

[0009] Preferably, fixing bolts are installed on the outer wall of the breaker hammer housing, and two sets of connecting bearings are fixed on the upper end of the breaker hammer housing.

[0010] Preferably, the adjustment mechanism comprises a drill rod, and the drill rod is fixed to the telescopic end of the driving member.

[0011] Preferably, a connecting groove is provided on the lower surface of the drill rod, and a hinge block is connected to the lower end of the connecting groove.

[0012] Preferably, a crushing head is fixed to the lower end of the hinged block.

[0013] Preferably, a fixing rod is fixed inside the hinge block, and both ends of the fixing rod pass through the outer wall of the drill rod.

[0014] Preferably, a limiting bolt is installed on the outer surface of the drill rod, and the end of the limiting bolt is abutted and connected with the outer wall of the hinge block.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Through the provided crushing mechanism, the spring pushes the movable block to move, which in turn causes the movable rod to drive the mounting plate to move. At this time, the cleaning brush inside the mounting plate can better contact the outer surface of the drill rod, thereby removing dust and impurities adhering to the outer surface of the drill rod, effectively reducing the entry of dust and impurities into the breaker.

[0017] 2. Through the setting adjustment mechanism, the limit bolt on the drill rod is unscrewed to release the fixation of the hinge block. With the cooperation of the connecting groove and the fixing rod, the crushing head can be rotated slightly to adjust the crushing angle. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4 An angle-adjustable hydraulic-gas combined breaker hammer comprises a breaker housing 1, a driving member 2 is fixed inside the breaker housing 1, a crushing mechanism for crushing objects is provided at the lower end of the driving member 2, and an adjusting mechanism for adjusting the crushing angle is fixed at the telescopic end of the driving member 2;

[0028] The crushing mechanism includes a protective shell 3, which is fixed to the lower end of the driving member 2. Mounting tubes 31 are fixed on both sides of the protective shell 3. Springs 32 are installed inside the two mounting tubes 31. The ends of the springs 32 are abutted and connected with movable blocks 33. The ends of the movable blocks 33 are fixed with movable rods 34 that pass through the interior of the protective shell 3. The ends of the movable rods 34 are fixed with mounting plates 35. The inner wall of the mounting plates 35 is fixed with cleaning brushes 36. The outer wall of the breaker hammer housing 1 is installed with fixing bolts 4. The upper end of the breaker hammer housing 1 is fixed with two sets of connecting bearings 5.

[0029] By adopting the above technical solution, before using the angle-adjustable hydraulic-gas combined breaker hammer, the breaker hammer housing 1 and the external driving device are first connected. The connecting bearing 5 provided on the breaker hammer housing 1 is convenient for assembly, and the fixing bolt 4 on the breaker hammer housing 1 can enhance the stability of the breaker hammer. The external hydraulic pipe and the interface at the upper end of the driving member 2 are connected and fixed, and then the driving member 2 is driven, so that the driving member 2 drives the drill rod 6 to move telescopically, and the crushing head 63 crushes the object. When the drill rod 6 moves telescopically, the spring 32 provided in the mounting tube 31 will push the movable block 33 to move, and then the movable rod 34 drives the mounting plate 35 to move. At this time, the cleaning brush 36 inside the mounting plate 35 better contacts the outer surface of the drill rod 6, and then removes the dust and impurities adhering to the outer surface of the drill rod 6, effectively reducing the entry of dust and impurities into the interior of the breaker hammer.

[0030] Specifically, such as Figure 2 and Figure 3 As shown, the adjustment mechanism includes a drill rod 6, which is fixed to the telescopic end of the driving member 2. A connecting groove 61 is provided on the lower surface of the drill rod 6, and a hinge block 62 is connected to the lower end of the connecting groove 61. A crushing head 63 is fixed to the lower end of the hinge block 62, and a fixing rod 64 is fixed inside the hinge block 62. Both ends of the fixing rod 64 pass through the outer wall of the drill rod 6. A limiting bolt 65 is installed on the outer surface of the drill rod 6, and the end of the limiting bolt 65 is abutted against the outer wall of the hinge block 62.

[0031] By adopting the above technical solution, when the crushing angle needs to be adjusted, the limit bolt 65 on the drill rod 6 can be unscrewed, thereby releasing the fixation of the hinge block 62. With the cooperation of the connecting groove 61 and the fixing rod 64, the crushing head 63 can be rotated slightly to adjust the crushing angle. After the adjustment is completed, the limit bolt 65 can be tightened so that the end of the limit bolt 65 contacts the outer wall of the hinge block 62, thereby fixing the crushing head 63.

[0032] Working principle: The driving part 2 drives the drill rod 6 to telescopic movement, and the crushing head 63 crushes the object. Through the mounting tube 31 arranged on the protective shell 3, when the drill rod 6 is performing telescopic movement, the spring 32 arranged in the mounting tube 31 will push the movable block 33 to move, and then the movable rod 34 drives the mounting plate 35 to move. At this time, the cleaning brush 36 inside the mounting plate 35 is in better contact with the outer surface of the drill rod 6, and then the dust and impurities adhering to the outer surface of the drill rod 6 are removed, effectively reducing the entry of dust and impurities into the inside of the breaker. When the crushing angle needs to be adjusted, the limit bolt 65 on the drill rod 6 can be unscrewed, thereby releasing the fixation of the hinge block 62. With the cooperation of the connecting groove 61 and the fixing rod 64, the crushing head 63 can be rotated slightly to adjust the crushing angle.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
