Description

Technical Field

[0001] This utility model relates to the field of hydraulic breaker technology, and in particular to an anti-splash electric hydraulic breaker. Background Technology

[0002] Electric hydraulic breakers, also known as hydraulic breakers or hydraulic breakers, are important engineering tools. They typically use high-pressure hydraulic oil as the working medium. Through the feedback coordination of a valve control system and a cylinder-piston rod system, the piston rod achieves rapid reciprocating motion within the cylinder, converting hydraulic energy into mechanical energy to strike the chisel and perform work. Some newer electro-hydraulic control breakers combine electrical sensors and solenoid valves to improve single-strike force and impact force. Other breakers use an electric motor as the power source, employing a gear transmission mechanism to achieve what is known as a high-speed electric breaker.

[0003] Existing electric hydraulic breakers are basically powered by a motor, which is then converted by a transmission structure to achieve the rapid reciprocating motion of the piston rod in the cylinder. This transmission structure is complex and has low transmission efficiency.

[0004] An existing patent (publication number: CN220301425U) discloses a fixed electric hydraulic breaker structure, which includes a frame, a cylinder installed inside the frame, a chisel installed inside the cylinder and extending from the bottom of the cylinder, and a piston rod installed inside the cylinder that can reciprocate to strike the chisel. A sliding armature is fixedly sleeved on the outside of the piston rod. It uses a first track group; when the first track group is energized, an electrical circuit is formed between guide rail one, the sliding armature, and guide rail two, thereby pushing the sliding armature downwards so that the piston rod can strike the chisel. This eliminates the need for a transmission structure, resulting in high transmission efficiency.

[0005] To address the aforementioned issues, while existing patents offer solutions that, by setting up a first track group, allow the piston rod to strike the chisel when the first track group is energized, eliminating the need for a transmission structure and resulting in high transmission efficiency, they lack protective capabilities when breaking objects. This leads to the fragments easily scattering and causing injury to workers. Summary of the Invention

[0006] The purpose of this invention is to provide an anti-splash electric breaker that can effectively reduce the splashing of debris during crushing. Through the connecting groove and limiting spring provided inside the protective shell, the movable shell can retract into the protective shell when the breaker body needs to move towards the object for crushing, thereby ensuring the normal crushing of the object by the breaker rod, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an anti-splash electric breaker, comprising a breaker body, a fixed handle fixed at one end of the breaker body, a protective mechanism for protecting against object splashes on the outer surface of the breaker body, and a filter mechanism for filtering dust on the outside of the protective mechanism.

[0008] The protective mechanism includes a first magnet, which is fixed to the outer surface of the breaker body. A second magnet is movably connected to the side wall of the first magnet. A protective shell is fixed to one side of the second magnet. A movable shell is telescopically connected to one end of the protective shell. A fixing ring is fixed to the end of the movable shell. A limit member is fixed to the other end of the movable shell.

[0009] Preferably, the inner wall of the protective shell is provided with a connecting groove that slides and connects with the limiting member, and a limiting spring disposed inside the connecting groove is abutted and connected to one side of the limiting member.

[0010] Preferably, the filtration mechanism includes an exhaust component that communicates with the outer surface of the movable housing.

[0011] Preferably, a filter screen is vertically arranged inside the exhaust component, and both ends of the filter screen are fixed with clips that slide and connect with the exhaust component.

[0012] Preferably, a movable plate that is movably connected to the exhaust component is fixed on one side of the filter screen, and a negative pressure fan is fixed inside the exhaust component by screws.

[0013] Preferably, the power output shaft of the breaker body is fixed with a connecting seat.

[0014] Preferably, a breaking rod is inserted into the inside of the connecting seat, and a fixing bolt is installed on the outer surface of the connecting seat to abut against the outer wall of the breaking rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The protective mechanism effectively reduces the splashing of debris during crushing. With the connecting groove and limiting spring inside the protective shell, the movable shell can retract into the protective shell when the breaker body needs to move towards the object for crushing, thus ensuring the normal crushing of the object by the breaker rod.

[0017] 2. The set filtration mechanism can draw the dust generated during crushing into the exhaust device. When it passes through the filter screen, the impurities in the air are filtered, and then the air is discharged to the outside, thereby reducing the dust in the air. Under the action of the locking strip, the movable plate can be manually pulled out for replacement. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 An anti-splash electric breaker includes a breaker body 1, a fixed handle 2 fixed to one end of the breaker body 1, a protective mechanism for protecting against splashing objects on the outer surface of the breaker body 1, and a filter mechanism for filtering dust on the outside of the protective mechanism.

[0028] The protective mechanism includes a first magnet 3, which is fixed to the outer surface of the breaker body 1. A second magnet 31 is movably connected to the side wall of the first magnet 3. A protective shell 32 is fixed to one side of the second magnet 31. A movable shell 33 is telescopically connected to one end of the protective shell 32. A fixing ring 34 is fixed to the end of the movable shell 33. A limiting member 35 is fixed to the other end of the movable shell 33. A connecting groove 36 is opened on the inner wall of the protective shell 32 and slides with the limiting member 35. A limiting spring 37 is abutted and connected to one side of the limiting member 35 and is placed inside the connecting groove 36. A connecting seat 5 is fixed to the power output shaft of the breaker body 1. A breaker rod 6 is inserted and connected inside the connecting seat 5. A fixing bolt 7 is installed on the outer surface of the connecting seat 5 and abuts and connects with the outer wall of the breaker rod 6.

[0029] By adopting the above technical solution, before using the anti-splash electric breaker, the breaker body 1 is placed in a suitable position. The breaker body 1 can be picked up using the fixed handle 2. Then, the protective shell 32 is put on the breaker body 1. With the cooperation of the first magnet 3 and the second magnet 31, the protective shell 32 can be limited. When in use, the breaker rod 6 is aligned with the object to be broken. At this time, the fixing ring 34 on the movable shell 33 contacts the outer surface of the object, so that the movable shell 33 and the protective shell 32 protect the breaker rod 6, thereby effectively reducing the splashing of debris generated during breaking. The motor inside the breaker body 1 starts, driving the breaker rod 6 to move and break the object. With the cooperation of the connecting groove 36 and the limiting spring 37 inside the protective shell 32 and the limiting member 35, when the breaker body 1 needs to be moved towards the object for breaking, the movable shell 33 can retract into the protective shell 32, thereby ensuring that the breaker rod 6 breaks the object normally.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the filtration mechanism includes an exhaust component 4, which is connected to the outer surface of the movable housing 33. A filter screen 41 is vertically arranged inside the exhaust component 4. Both ends of the filter screen 41 are fixed with clips 42 that are slidably connected to the exhaust component 4. A movable plate 43 that is movably connected to the exhaust component 4 is fixed on one side of the filter screen 41. A negative pressure fan 44 is fixed inside the exhaust component 4 by screws.

[0031] By adopting the above technical solution, the negative pressure fan 44 is started through the exhaust component 4 set on the movable shell 33, so that the negative pressure is generated inside the movable shell 33, which can suck the dust generated during crushing into the exhaust component 4. When passing through the filter screen 41, the impurities in the air are filtered, and then the air is discharged to the outside, thereby reducing the dust from being dispersed in the air. Under the action of the locking strip 42, the movable plate 43 can be manually pulled to remove the filter screen 41 for replacement. By unscrewing the fixing bolt 7 on the connecting seat 5, the fixing of the crushing rod 6 can be released, so that the crushing rod 6 can be disassembled and replaced.

[0032] Working principle: The hydraulic breaker body 1 can be picked up through the fixed handle 2, and the breaking rod 6 is aligned with the object to be broken. At this time, the fixing ring 34 on the movable shell 33 contacts the outer surface of the object, so that the movable shell 33 and the protective shell 32 protect the breaking rod 6. The hydraulic breaker body 1 drives the breaking rod 6 to move and break the object. Through the connecting groove 36 and the limiting spring 37 set in the protective shell 32, with the cooperation of the limiting part 35, when the hydraulic breaker body 1 moves towards the object to break it, the movable shell 33 can retract into the protective shell 32, thereby ensuring that the breaking rod 6 breaks the object normally. The negative pressure fan 44 is started, so that a negative pressure is generated inside the movable shell 33, which can suck the dust generated during the breaking into the exhaust part 4. When passing through the filter screen 41, the impurities in the air are filtered, and then the air is discharged to the outside.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
