It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] like Figures 1-8 As shown, the utility model provides a silent breaker hammer for a skid loader, comprising: a breaker hammer body 1, on which a protection mechanism 2 is provided;

[0029] The protective mechanism 2 includes a first ring 201, a protective shell 202 and two U-shaped blocks 209. The bottom and top of the protective shell 202 are fixed with plug-in plates 203. Two rectangular holes 204 are opened on one side of the first ring 201. Two cylindrical grooves 205 are opened on the front surface of the first ring 201 and the rear surface of the first ring 201. The inner wall of each cylindrical groove 205 is installed with a spring 206. The top of the inner wall of one rectangular hole 204 and the bottom of the inner wall of the other rectangular hole 204 are fixed with a plug-in plate 203. There are two cylindrical holes 207, and a cylindrical block 208 is movably sleeved inside each cylindrical hole 207. The first ring 201 is fixedly sleeved on the outer surface of the breaker body 1 near one end. One end of the breaker body 1 is movably sleeved inside the protective shell 202. The side of the protective shell 202 close to the spring 206 contacts the side of the first ring 201. The two inserts 203 are movably sleeved inside the two rectangular holes 204 respectively. The inner walls of the two U-shaped blocks 209 are in contact with the outer wall of the first ring 201. In contact, each spring 206 is movably sleeved inside each cylindrical groove 205, and the four springs 206 are divided into two groups. The opposite ends of the two groups of springs 206 are respectively installed with the inner walls of the two U-shaped blocks 209, and the four cylindrical blocks 208 are divided into two groups. The opposite ends of each group of cylindrical blocks 208 are movable through the opposite sides of the two plug-in plates 203, and the opposite ends of each group of cylindrical blocks 208 are movably embedded in the bottom of the inner wall of one of the rectangular holes 204 and the top of the inner wall of the other rectangular hole 204. The opposite ends of the cylindrical blocks 208 are in contact with the inner wall of each U-shaped block 209 respectively. The outer wall of the first ring 201 is fixedly sleeved with a second ring 3 near both sides. A perforated plate 4 is fixed between the tops of the two second rings 3 and between the bottoms of the two second rings 3. Auxiliary blocks 5 are fixed to the outer walls of the two U-shaped blocks 209. The two sides of each U-shaped block 209 are in contact with the opposite sides of the two second rings 3 respectively, and the outer wall of each U-shaped block 209 is in contact with the opposite side of the two perforated plates 4.

[0030] The effect achieved is that when it is necessary to inspect the drill rod end of the silent breaker hammer for the skid loader, a pulling force is first applied to each of the two auxiliary blocks 5, and the two auxiliary blocks 5 are moved back to back. At this time, the two moving auxiliary blocks 5 will drive the corresponding U-shaped blocks 209 to move, and the two moving U-shaped blocks 209 will cause the corresponding set of springs 206 to undergo elastic deformation under the cooperation of the first ring 201 and the corresponding cylindrical groove 205. When the inner walls of the two U-shaped blocks 209 are separated from the opposite sides of the corresponding set of cylindrical blocks 208, the movement of the two auxiliary blocks 5 is stopped first. At this time, the two stopped auxiliary blocks 5 will cause the corresponding U-shaped blocks 209 to stop moving, and then each cylindrical block 208 is removed from the corresponding cylindrical hole 208 by using the cooperation of the tool and the two perforated plates 4. 7, then apply a force to each of the two plug plates 203, so that the two plug plates 203 move in the direction of one side. At this time, the two moving plug plates 203 will drive the protective shell 202 to move. When the two plug plates 203 are moved out from the corresponding rectangular holes 204, the protective shell 202 and the two plug plates 203 can be directly removed, and then the force applied to the two auxiliary blocks 5 is released. At this time, the two U-shaped blocks 209 will be reset to their initial positions under the cooperation of the first ring 201, the two second rings 3, the two perforated plates 4, the corresponding cylindrical grooves 205 and the corresponding set of springs 206. Then the drill rod end of the silent breaker hammer for the skid loader can be checked. When it is necessary to protect the drill rod end of the silent breaker hammer for the skid loader, just follow the above-mentioned operating steps and perform the reverse operation.

[0031] Working principle: When it is necessary to inspect the drill rod end of the silent breaker hammer for the skid loader, a pulling force is first applied to each of the two auxiliary blocks 5, and the two auxiliary blocks 5 are moved in opposite directions. At this time, the two moving auxiliary blocks 5 will drive the corresponding U-shaped blocks 209 to move, and the two moving U-shaped blocks 209 will cause the corresponding set of springs 206 to undergo elastic deformation under the cooperation of the first ring 201 and the corresponding cylindrical groove 205. When the inner walls of the two U-shaped blocks 209 are separated from the opposite sides of the corresponding set of cylindrical blocks 208, the movement of the two auxiliary blocks 5 is stopped first. At this time, the two stopped auxiliary blocks 5 will cause the corresponding U-shaped blocks 209 to stop moving. Then, each cylindrical block 208 is removed from the corresponding cylindrical hole 207 by using the cooperation of tools and two perforated plates 4. When the two plug plates 203 are both moved out from the corresponding rectangular holes 204, the protective shell 202 and the two plug plates 203 can be directly removed, and then the force applied to the two auxiliary blocks 5 is released. At this time, the two U-shaped blocks 209 will be reset to their initial positions under the cooperation of the first ring 201, the two second rings 3, the two perforated plates 4, the corresponding cylindrical grooves 205 and the corresponding set of springs 206. Then the drill rod end of the silent breaker hammer for the skid loader can be checked. When it is necessary to protect the drill rod end of the silent breaker hammer for the skid loader, just follow the above-mentioned operating steps and perform the reverse operation.

[0032] The breaker body 1 is a silent breaker hammer for a skid loader, which generally includes the following main components:

[0033] Shell: protects internal components and also provides a certain degree of sound insulation.

[0034] Piston: It generates impact force through reciprocating motion, striking the drill rod to perform crushing operations.

[0035] Cylinder body: provides movement space for the piston and cooperates with the piston to form a sealed hydraulic chamber.

[0036] Drill rod: directly contacts the work object, transmits the impact force generated by the breaker hammer to hard objects such as rock or concrete, and realizes the crushing operation.

[0037] Hydraulic system: provides power for the breaker and drives the piston movement by controlling the flow and pressure of hydraulic oil.

[0038] Shock absorber: reduces the vibration and impact of the breaker during operation, protecting the skid steer loader and operators.

[0039] Its working principle: The silent breaker hammer used in skid steer loader is powered by the hydraulic system, which makes the piston reciprocate at high speed in the cylinder. When the piston rises, hydraulic oil enters the bottom of the cylinder and pushes the piston upward. When the piston descends, the hydraulic oil is discharged from the top of the cylinder. The piston falls rapidly under the action of gravity and hydraulic pressure, generating a strong impact force. This impact force is transmitted to the working object through the drill rod, causing hard objects such as rock or concrete to break. Because the silent breaker hammer adopts special design and technology, such as optimized internal structure, shock absorption device and sound insulation material, it can effectively reduce noise and vibration during operation. The shock absorption device can absorb most of the vibration generated by the breaker hammer, reducing the impact on the skid steer loader and operator. The sound insulation material and special shell structure can block and absorb noise, which greatly reduces the noise emitted by the breaker hammer during operation. In actual operation, the operator controls the operation of the breaker hammer through the skid steer loader's joystick, including starting, stopping and adjusting the impact force. The hydraulic system adjusts the flow and pressure of the hydraulic oil according to the operator's instructions, thereby controlling the movement speed and impact force of the piston to adapt to different crushing tasks.
