Description

Technical Field

[0001] This invention relates to the field of hydraulic breakers, specifically to hydraulic breakers with protective devices. Background Technology

[0002] In engineering fields such as building demolition, mining, and road repair, hydraulic breakers, as core impact crushing equipment, are widely used in crushing operations of hard materials such as rocks, concrete, and brick walls due to their high-efficiency crushing capabilities.

[0003] In existing technologies, when a hydraulic breaker is in operation, the high-frequency impact of the chisel rod on materials such as walls and rocks generates a large amount of high-speed flying debris and waste. Some of the debris has high kinetic energy and can easily cause impact injuries to the operator's head and limbs. Therefore, it is necessary to install protective structures to improve construction safety.

[0004] However, most existing hydraulic breakers have fixed and non-adjustable protective structures. Even the few adjustable protective devices require manual adjustment of the angle. When the chisel is working on different angles of the crushing area, the protective components cannot automatically adapt to the working angle and have low contact with the crushing area, causing the crushed stone to fly out of the gaps, which can easily cause damage to the operator and surrounding equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a hydraulic breaker with a protective device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic breaker with a protective device, comprising a hydraulic breaker body, wherein a chisel is disposed within the hydraulic breaker body, a purification component is fixedly connected to the lower end of the hydraulic breaker body, the output direction of the purification component is vertical, a fixing plate is fixedly connected to the surface of the hydraulic breaker body, a guide component is disposed on the surface of the fixing plate, a protective component is elastically connected to the lower end of the guide component, and the chisel is located within the protective component.

[0007] Preferably, the purification component includes a water tank, which is fixedly connected to the surface of the breaker body. A conduit is fixedly connected to the output end of the water tank, and the other end of the conduit passes through a fixing plate and is connected to an mounting plate. The mounting plate is fixedly connected to the lower end of the breaker body, and several atomizing nozzles are evenly fixedly connected to the surface of the mounting plate. The chisel does not contact the mounting plate.

[0008] Preferably, the guide assembly includes a spring steel tie rod and a guide frame.

[0009] Preferably, one end of the connecting rod passes through the fixing plate and the mounting plate in sequence and is fixedly connected to the connecting block. The connecting rod is slidably connected to the fixing plate and the mounting plate. There are four spring steel tie rods, which are located at the four corners of the surface of the mounting plate. The spring steel tie rods pass through the mounting plate and are slidably connected to it.

[0010] Preferably, the protective assembly includes an upper horizontal bar, an upper horizontal bar, a lower horizontal bar, a lower horizontal bar, and a column. The two sides of the upper surface of the column are rotatably connected to the upper horizontal bar and the upper horizontal bar, respectively, and the two sides of the lower surface of the column are rotatably connected to the lower horizontal bar and the lower horizontal bar.

[0011] Preferably, four columns are provided, and grooves are provided at both the upper and lower ends of one side of each column. Rotating seats are fixedly connected to both the upper and lower ends of the side adjacent to the groove surface.

[0012] Preferably, there are two upper crossbars, one and two upper crossbars. Both ends of the upper crossbar two are rotatably connected to hinges via bearings.

During the process, the crushed stone is blocked by steel wire one and steel wire two, and the crushing vibration is absorbed by the reinforced spring, ensuring that the protective component keeps in contact. The spring steel tie rod helps the column to quickly reset. The whole system is adaptable to multi-angle operation and has strong adaptability. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-6 This invention provides a technical solution: a hydraulic breaker with a protective device, including a hydraulic breaker body 1. The hydraulic breaker body 1 can be installed on a robotic arm through holes on its surface. A purification component 4 is provided at the lower end of the hydraulic breaker body 1. The purification component 4 includes a water tank 40, which contains liquid for dust removal. The water tank 40 is fixedly connected to the surface of the hydraulic breaker body 1. A conduit 41 is fixedly connected to the output end of the water tank 40. A water pump is provided inside the water tank 40. The water pump can pump the liquid into the conduit 41 and increase the pressure. The other end of the conduit 41 passes through a fixing plate 3 and is connected to a mounting plate 42. The mounting plate 42 is fixedly connected to the lower end of the hydraulic breaker body 1. Several atomizing nozzles 43 are evenly fixedly connected to the surface of the mounting plate 42. The liquid can be sprayed out through the atomizing nozzles 43 to treat the dust raised during operation. The chisel 2 does not contact the mounting plate 42. The atomizing nozzles 43 are located around the chisel 2.

[0021] A guide assembly 6 is provided on the surface of the breaker body 1. The guide assembly 6 includes a spring steel rod 65 and a guide frame 60. The spring steel rod 65 is elastic. Two guide frames 60 are provided, and the two guide frames 60 are fixedly connected to the two sides of the breaker body 1 respectively. A slide plate 61 is slidably connected to the inner wall of the guide frame 60. A reinforcing spring 62 and a connecting rod 63 are fixedly connected to the surface of the slide plate 61. The reinforcing spring 62 facilitates the quick return of the slide plate 61. The other end of the reinforcing spring 62 is fixedly connected to the upper end of the inner wall of the guide frame 60. When the slide plate 61 is in a compressed state, it will be subjected to the reverse thrust of the reinforcing spring 62. One end of the connecting rod 63 passes through the fixed plate 3 and the mounting plate 42 in sequence and is fixedly connected to the connecting block 64. The connecting rod 63 can be moved through the connecting block 64. The connecting rod 63 is slidably connected to the fixed plate 3 and the mounting plate 42. There are four spring steel tie rods 65. The four spring steel tie rods 65 are located at the four corners of the surface of the mounting plate 42. The mounting plate 42 is fixedly connected to the breaker body 1. The spring steel tie rods 65 pass through the mounting plate 42 and are slidably connected to it.

[0022] The lower end of the breaker body 1 is provided with a protective component 5, which can protect the chisel 2. The protective component 5 includes an upper crossbar 50, an upper crossbar 52, a lower crossbar 54, a lower crossbar 55 and a column 56. The two sides of the upper surface of the column 56 are rotatably connected to the upper crossbar 50 and the upper crossbar 52 respectively, and the two sides of the lower surface of the column 56 are rotatably connected to the lower crossbar 54 and the lower crossbar 55 respectively. The column 56 can rotate back and forth or left and right.

[0023] Four columns 56 are provided, each located directly below the spring steel tie rod 65. Grooves are formed at both the top and bottom ends of one side of each column 56. Rotating seats 57 are fixedly connected to both the top and bottom ends of the side adjacent to the groove. The rotating seats 57 are arc-shaped with arc-shaped grooves on their surfaces. Two upper crossbars 50 and two upper crossbars 52 are provided. Both ends of the upper crossbar 52 are rotatably connected to hinges 53 via bearings. The hinges 53 can rotate. The other end of the hinges 53 is rotatably connected to the grooves on the upper surface of the column 56 via a rotating shaft, allowing the column 56 to swing. Both ends of the upper crossbar 50... A fixed connection is provided with a limiting seat 51. The limiting seat 51 is rotatably connected to the rotating seat 57 on the upper surface of the column 56 via a rotating shaft. The rotating shaft can slide in the arc groove. There are two lower crossbars 54 and two lower crossbars 55. Both ends of the lower crossbar 54 are fixedly connected with hinges 53. The other end of the hinge 53 is rotatably connected to the groove on the lower surface of the column 56 via a rotating shaft. When the column 56 swings, the lower crossbars 54 and 55 swing accordingly. Both ends of the lower crossbar 55 are rotatably connected to the rotating seat 57 on the lower surface of the column 56 via a rotating shaft. Two adjacent columns 56 can form a quadrilateral.

[0024] The protective component 5 contains several steel wires 58 and 59. Both steel wires 58 and 59 are high-elastic stainless steel wires, possessing excellent tensile and bending toughness. Combined with the elastic steel rings at the edges, they effectively adapt to the deformation of the protective component 5. Several steel wires 58 are fixedly connected to the surfaces of the upper crossbar 50 and upper crossbar 52. The other end of the steel wire 58 connected to the upper crossbar 50 is fixedly connected to the lower crossbar 54, and the other end of the steel wire 58 connected to the upper crossbar 52 is fixedly connected to the lower crossbar 55. All steel wires 58 are vertically downwards. The two ends of the steel wires 59 are respectively... The two columns 56 are fixedly connected, and steel wires 59 are fixedly connected to both sides of each column 56. In the initial state, steel wires 58 and 59 are perpendicular to each other. The dense steel wires 58 and 59 can effectively block the flying stones. The protective component 5 is a cube with four sides. By utilizing the instability of the quadrilateral, when the column 56 swings, two sides will become parallelograms and the other two sides will become inclined quadrilaterals. The swing range of the column 56 is limited by the arc groove and the groove, so as to avoid the lower crossbar 54 and the lower crossbar 55 from contacting the chisel 2 during the swing.

[0025] The lower ends of the four spring steel rods 65 each pass through a column 56 and are fixedly connected to its lower end. The two connecting blocks 64 are fixedly connected to the two upper crossbars 50 respectively. When the protective component 5 moves up and down, it can be easily reset by the reinforcing spring 62. The column 56 can be quickly reset after swinging by the spring steel rods 65.

[0026] In actual use, the atomizing nozzle 43 in the purification component 4 can suppress dust generated during the crushing process. When the chisel 2 approaches the crushing area, the column 56 will swing unidirectionally under the action of the bottom round end, thereby automatically adjusting the overall tilt of the protective component 5 so that its angle is consistent with the angle of the crushing area, thus effectively fitting. The crushed stone generated during the process will be blocked by the steel wire 1 58 and steel wire 2 59. The vibration of the breaker hammer during operation will be absorbed by the reinforcing spring 62, so that the protective component 5 can always fit the area. The spring steel tie rod 65 can make the column 56 quickly reset. It has strong overall adaptability and can effectively deal with crushing work at various angles.
