[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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Example 1;

[0027] Please see Figures 1 to 4This utility model provides a technical solution: a low-noise right-angle hydraulic breaker, mainly used in building excavation, comprising a hydraulic breaker body 1, a protective shell 2 detachably connected to the lower end of the outer surface of the hydraulic breaker body 1, a splash guard 14 fixedly connected to the lower end of the protective shell 2, an observation window 15 on the side of the protective shell 2, a positioning shaft 16 inserted into the inner wall of the connecting frame 8 for connection, a nut threadedly connected to one end of the positioning shaft 16 for fixing, a flexible hose 3 detachably connected to the upper end of the protective shell 2 for transmission, a suction pump 4 threadedly connected to one end of the flexible hose 3, an ash discharge pipe 5 threadedly connected to the output end of the suction pump 4 for transmission, and a splash guard 14. It is an extended protective structure at the lower end of the protective shell 2, which further expands the protection range and can effectively block small stones or debris from splashing out from the gaps under the protective shell 2 during crushing operations. It is especially effective for the core area where the chisel 7 contacts the object to be crushed, improving the protection of equipment and personnel. At the same time, the observation window 15 can observe the core area of ​​the crushing operation, helping operators to grasp the crushing progress and the accuracy of the crushing position in real time, so as to adjust the operating parameters in time and improve crushing efficiency and accuracy. The connecting frame 8 and the positioning shaft 16 are used to connect the breaker hammer body 1 to external power equipment such as excavators and loaders, realizing the fixation of the breaker hammer body 1 to the power source and the power transmission. It is a key structure for installing the breaker hammer body 1 onto the operating machinery.

[0028] Example 2;

[0029] Please see Figures 2 to 4One end of the ash discharge pipe 5 is detachably connected to a dust box 6 for storage. A lid 9 for sealing is detachably connected to one side of the dust box 6, and a viewing window 10 for observation is provided on the other side of the dust box 6. A handle 11 for gripping is detachably connected to one side of the lid 9. The outer surface of the handle 11 is provided with friction texture for anti-slip. Ear plates 12 are fixedly connected to both the upper and lower sides of the dust box 6. A threaded post 13 for fixing is inserted into one side of the ear plate 12. One side of the dust box 6 is detachably connected to one side of the breaker hammer body 1. The lid 9 closes on one side of the dust box 6 to prevent the dust stored in the dust box 6 from leaking due to equipment vibration or movement, and also to prevent external debris from entering the interior of the dust box 6. The detachable design also allows operators to open the lid 9 periodically to clean and transfer the dust stored inside. To ensure that the dust bin 6 has continuous storage capacity, the viewing window 10 is made of transparent or semi-transparent material, allowing operators to visually view the dust level in the dust bin 6 without opening the lid 9, and promptly determine whether cleaning is needed, thus preventing the collection system from failing due to dust overflow. The handle 11 provides a convenient grip point for opening and closing the lid 9, and the friction texture on the outer surface increases the friction between the hand and the handle 11, preventing the operator from slipping when gripping, and improving the convenience of disassembling and installing the lid 9. The ear plate 12 is a fixed auxiliary structure for the dust bin 6. By inserting a threaded post 13 into one side of the ear plate 12, the dust bin 6 can be further fixed to the breaker body 1 or external equipment, enhancing the connection stability between the dust bin 6 and the breaker body 1, and preventing the dust bin 6 from shifting due to vibration during operation.

[0030] Example 3;

[0031] Please see Figure 3 The lower end of the hydraulic breaker body 1 is detachably connected to a chisel 7 for crushing, and the upper end of the hydraulic breaker body 1 is detachably connected to a connecting frame 8 for fixing. Reinforcing ribs 17 are fixedly connected to both the left and right sides of the hydraulic breaker body 1. A positioning hole is provided on one side of the hydraulic breaker body 1. The chisel 7, being the direct execution component for crushing operations, connects to the hydraulic breaker body 1 at one end and contacts the object to be crushed at the other. The power of the hydraulic breaker body 1 is transmitted to the object to be crushed through the chisel 7. The impact and compression action of the chisel 7 achieves the crushing of the object, serving as the execution end of the crushing action. The reinforcing ribs 17 are structural reinforcement components of the hydraulic breaker body 1, fixed to the left and right sides of the body. By increasing the local structural thickness and strength of the body, the impact resistance and deformation resistance of the hydraulic breaker body 1 are improved. During crushing operations, the body bears a large impact force, and the reinforcing ribs 17 can disperse the stress, preventing cracks or deformation due to long-term stress and extending the service life of the equipment.

[0032] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0033] In this invention, the working steps of the device are as follows:

[0034] First, connect the breaker body 1 to external power equipment such as an excavator or loader via the upper connecting frame 8. Insert the positioning shaft 16 into the inner wall of the connecting frame 8, and tighten the nut on one end of the positioning shaft 16 to ensure a secure connection between the breaker body 1 and the external power equipment without any looseness or gaps. Operate the external power equipment to move the breaker body 1 to the target crushing area of ​​the building to be excavated. Align the contact point between the chisel 7 and the object to be crushed through the observation window 15 on the side of the protective shell 2. Adjust the angle and height of the breaker to ensure that the chisel 7 is vertical or conforms to the surface to be crushed as required by the operation. Start the crushing function of the external power equipment. Power is transmitted to the chisel 7 through the breaker body 1. The chisel 7 is driven by the breaker body 1. The high-frequency impact and squeezing force generated by the movement are monitored in real time through the observation window 15 to check the crushing progress and the position accuracy of the chisel 7. At the same time as the crushing operation starts, the dust suction pump 4 is turned on. The dust suction pump 4 forms a negative pressure inside the protective shell 2 through its own suction action, which sucks the dust generated during the crushing process from the protective shell 2. The dust is transmitted to the dust suction pump 4 through the hose 3, and then stably transported to the dust box 6 for storage through the dust outlet pipe 5 at the output end of the dust suction pump 4. During the operation, the operator regularly observes the amount of dust in the dust box 6 through the viewing window 10 on one side of the dust box 6. If the dust is found to be close to the upper limit of the capacity of the dust box 6, the crushing operation must be stopped and the dust box 6 should be cleaned first to avoid the dust overflowing and causing the collection system to fail.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
