Description

Technical Field

[0001] The utility model relates to the technical field of breaker hammers, in particular to a breaker hammer with an anti-rebound function. Background Art

[0002] A breaker hammer is a heavy equipment used for demolition of concrete and rock, typically mounted on an excavator. It uses a hydraulic system to convert impact force into a powerful impact, breaking up hard materials. Breakers are widely used in building demolition, mining, and infrastructure maintenance. Their main components include the impactor, housing, and hydraulic system. Different models of breakers are suitable for materials of varying hardness and working environments.

[0003] A traditional breaker hammer consists of a cylinder, bracket, and drill rod. Energy is transferred to the piston via a hydraulic cylinder. The piston's reciprocating motion is transmitted to the work surface via the drill rod, thereby breaking hard objects. As the piston moves upward, the gas in the nitrogen chamber is compressed, increasing the system pressure. As the piston moves downward, the compressed nitrogen releases energy, which, combined with the hydraulic oil, accelerates the piston downward, striking the drill rod and completing the breaking process.

[0004] When a traditional breaker hammer hits a hard object, the impact force will be transmitted back through the hammer body, causing the hammer head, connecting rod and other components to vibrate and collide, thereby accelerating the wear of parts and causing accidents. Therefore, a breaker hammer with anti-rebound function is proposed to solve the above problem. Utility Model Content

[0022] The utility model has the following beneficial effects:

[0023] 1. In the utility model, the piston rod descends and drives the pressing plate to squeeze the fixed plate 2, so that the rotating bar 1 and the rotating bar 2 rotate, thereby pushing the sliding block to slide and squeeze the first spring, causing it to contract, and at the same time allowing the damper to be squeezed, thereby absorbing the squeezing force and reducing the transmission of the reaction force. This solves the problem that when some breaker hammers hit hard objects, the impact force will be transmitted in the opposite direction through the hammer body, causing the hammer head, connecting rod and other components to vibrate and collide, thereby accelerating the wear of parts and causing accidents. The above structure improves the protection of the equipment.

[0024] 2. In the utility model, the dust hood starts working by starting the fan, absorbing the dust in the crushing process, and finally falling into the collection box to achieve a dust-proof effect. The mounting block is pulled out from the inside of the clamping block by pulling the mounting plate to achieve the effect of disassembling the filter screen, solving the problem that some breakers generate a lot of dust during the crushing process. This dust not only pollutes the working environment, but also affects the health of the operator. The practicality of the equipment is improved through the above structure.

[0032] 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.

[0033] Reference Figure 1-Figure 3 The utility model provides an embodiment of a breaker hammer with an anti-rebound function, comprising a cylinder body 1, a piston rod 4 is slidably connected to the inside of the cylinder body 1, a pressing plate 5 is fixedly connected to the side wall of the piston rod 4, a cavity 6 is opened inside the cylinder body 1, the side wall of the pressing plate 5 is slidably connected to the inside of the cavity 6, a fixing plate 8 is fixedly connected to the inside of the cavity 6, a rubber block 9 is fixedly connected to the upper surface of the fixing plate 8, a fixing plate 2 15 is fixedly connected to the upper surface of the rubber block 9, a fixing sleeve 10 is fixedly connected to the inside of the rubber block 9, a rotating bar 11 is rotatably connected to the side wall of the fixing plate 8, and a sliding block 12 is rotatably connected to one end of the rotating bar 11. The side wall of the block 12 is slidably connected to the inside of the fixed sleeve 10, and a buffer assembly is provided inside the fixed sleeve 10 for buffering the piston knocking force. The side wall of the sliding block 12 is rotatably connected to a rotating bar 2 14, and one end of the rotating bar 2 14 is rotatably connected to the side wall of the fixed plate 2 15. The upper surface of the fixed plate 1 8 and the lower surface of the fixed plate 2 15 are fixedly connected to a mounting block 16, and a damper 17 is fixedly connected between the mounting blocks 16. The buffer assembly includes a first spring 13, one end of the first spring 13 is fixedly connected to the inside of the fixed sleeve 10, and the other end of the first spring 13 is fixedly connected to the side wall of the sliding block 12. A nitrogen storage chamber 2 is opened inside the cylinder body 1, an accumulator 3 is provided inside the cylinder body 1, and a drill rod 7 is provided inside the cylinder body 1;

[0034] During the operation of the crushing equipment to crush materials, when the piston rod 4 moves downward, it will exert a knocking effect on the drill rod 7. This downward movement of the piston rod 4 not only directly drives the synchronous downward movement of the pressing plate 5, but also the downward movement of the pressing plate 5 further exerts pressure on the fixed plate 2 15. The fixed plate 2 15 squeezed by the pressing plate 5 will cause the rotating bar 2 14 to rotate; the rotating bar 11 will also begin to rotate due to the squeezing. The rotation of these two rotating bars pushes the sliding block 12 to move inside the fixed sleeve 10, thereby exerting pressure on the first spring 13 to achieve the initial buffering effect of the equipment. In addition, when the fixed plate 2 15 is squeezed, the damper 17 will absorb the force generated by the squeezing, thereby effectively reducing the adverse effects that the vibration generated by the piston rod 4 during operation may have on the entire equipment. Through this design, the stability and service life of the equipment are significantly improved, while also ensuring the efficiency and safety of the crushing operation.

[0035] Reference Figure 4-Figure 5 The lower surface of the cylinder body 1 is fixedly connected to a dust cover 18, the side wall of the cylinder body 1 is fixedly connected to a collection box 19, the upper surface of the collection box 19 is fixedly connected to a fan 20, the output end of the fan 20 is fixedly connected to a delivery pipe 21, one end of the delivery pipe 21 is fixedly connected to the inside of the collection box 19, the inside of the collection box 19 is slidably connected to a drawer 24, a filter 23 is provided inside the collection box 19, the side wall of the collection box 19 is fixedly connected to a connecting pipe 22, one end of the connecting pipe 22 is fixedly connected to the dust cover Inside 18, the side wall of the filter screen 23 is fixedly connected to the mounting plate 25, the side wall of the mounting plate 25 is fixedly connected to the mounting block 26, the side wall of the collection box 19 is fixedly connected to the fixing plate three 27, the side wall of the fixing plate three 27 is rotatably connected to the clamping block 28, and a second spring 29 is provided on the lower surface of the clamping block 28, one end of the second spring 29 is fixedly connected to the side wall of the fixing plate three 27, and the other end of the second spring 29 is fixedly connected to the side wall of the clamping block 28, and the side wall of the mounting block 26 is engaged inside the clamping block 28.

[0036] During the operation of the equipment for material crushing, the operator can start the fan 20 to activate the dust hood 18. The main function of the dust hood 18 is to capture and absorb various dust particles generated during the crushing operation. After these dust particles are sucked in by the suction force of the dust hood 18, they will be transported to the inside of the collection box 19 through the connecting pipe 22. Inside the collection box 19, these dust particles will be effectively collected and stored, thereby greatly reducing the adverse effects of dust on the working environment and the health of the operator. When the filter 23 needs to be cleaned, the operator can pull the mounting plate 25 to disengage the mounting block 26 from the clamping block 28. After the mounting block 26 is separated from the clamping block 28, the operator can pull the filter 23 out of the interior of the collection box 19. After pulling out the filter 23, the operator can thoroughly clean it to remove accumulated dust and other impurities to ensure that its filtering effect is optimal. After cleaning, the filter 23 can be reinstalled into the collection box 19.

[0037] Working principle: When the equipment is used for crushing work and the piston rod 4 slides down to strike the drill rod 7, the downward movement of the piston rod 4 drives the pressing plate 5 to slide down, thereby squeezing the fixed plate 2 15. After the fixed plate 2 15 is squeezed, the rotating bar 2 14 is rotated. At the same time, the rotating bar 11 is also rotated due to the squeezing force, and then pushes the sliding block 12 to squeeze the first spring 13 inside the fixed sleeve 10, thereby achieving preliminary buffering. At the same time, the squeezing of the fixed plate 2 15 allows the damper 17 to absorb the squeezing force generated, effectively reducing the impact of the vibration of the piston rod 4 on the equipment. During the crushing process of using the equipment, the fan 20 can be started to make the dust collection hood 18 start working, so that it sucks in the dust generated during the work and transports it into the collection box 19 through the connecting pipe 22 for collection, effectively reducing the impact of the dust. When the filter 23 needs to be cleaned, the mounting block 26 can be detached from the clamping block 28 by pulling the mounting plate 25, and then the filter 23 can be pulled out from the collection box 19 for cleaning.
