Technical Field

[0001] This utility model belongs to the field of dust cover technology, specifically relating to an accordion-style dust cover for a crushing cone. Background Technology

[0002] Excavator-type hydraulic breakers are engineering equipment modified from excavators and fitted with hydraulic breakers to meet the needs of excavating hard rock strata on construction sites. Their main applications include: rock excavation where blasting is not suitable, projects with relatively small rock excavation volumes, and projects requiring high precision in rock excavation. During operation, the breaker primarily breaks rocks by impacting them with the up-and-down vibration of its hammer, producing flying rock debris and dust. Existing hydraulic breakers on the market use an integrated protective cover, which, while providing protection, obstructs the operator's view. Utility Model Content

[0003] The purpose of this utility model is to provide an accordion-style dustproof and dust-reducing cover for crushing cones that has a simple structure and reasonable design in order to solve the above problems.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example

[0020] Please see Figure 1 An accordion-style dustproof cover for a breaker cone includes a protective mechanism 5, which is mounted on a breaker hammer 4. The breaker hammer 4 is mounted on a forearm 3, the forearm 3 is mounted on a boom 2, and the boom 2 is mounted on the excavator body 1. A spraying mechanism 6 is provided between the protective mechanism 5 and the excavator body 1.

[0021] The protective mechanism 5 is used to protect against flying stones and dust during crushing, while the spraying mechanism 6 is used to spray and suppress dust during crushing, effectively reducing the occurrence of dust during crushing.

[0022] Please see Figure 2 and Figure 4 The protective mechanism 5 includes a square clamp assembly 56 that is fixedly fitted onto the outside of the breaker hammer 4. The square clamp assembly 56 includes a square clamp body 561 that is fitted onto the outside of the breaker hammer 4. Two fixing blocks 562 are symmetrically fixedly connected on the right side of the square clamp body 561. The two fixing blocks 562 fit together. A screw 563 is movably passed through the middle of the two fixing blocks 562. Two nuts 564 are symmetrically threaded on the screw 563. An accordion dust cover 57 is fixedly installed at the bottom of the square clamp body 561.

[0023] Please see Figure 2 , Figure 3 and Figure 4 The accordion dust cover 57 is U-shaped with its opening facing the excavator body 1. A U-shaped base plate 59 is fixedly installed at the bottom of the accordion dust cover 57. Two ear plates 58 are symmetrically fixedly connected to the U-shaped base plate 59. Steel ropes 53 are fixedly installed on the top of the two ear plates 58. Two No. 1 fixed pulleys 51 are symmetrically installed on the boom 2. Two No. 2 fixed pulleys 52 and two No. 3 fixed pulleys 54 are symmetrically installed on the forearm 3. Two No. 4 fixed pulleys 55 are symmetrically installed on the breaker hammer 4. The steel rope 53 passes through the No. 4 fixed pulley 55, the No. 3 fixed pulley 54 and the No. 2 fixed pulley 52 in sequence and is then fixedly connected to the No. 1 fixed pulley 51.

[0024] During use, the protective mechanism 5 requires initial installation. First, the square clamp body 561 is fitted and fixed onto the breaker hammer 4. Then, the screw rod 563 is inserted between the two fixing blocks 562, and the nut 564 is tightened onto the screw rod 563. The screw rod 563 and nut 564 secure the square clamp body 561 to the breaker hammer 4. As the boom 2 descends, the forearm 3 and the breaker hammer 4 descend synchronously, simultaneously lowering the protective mechanism 5. The U-shaped base plate 59 of the protective mechanism 5 contacts the ground, and the accordion dust cover 57 protects the breaker during operation. The system protects against flying stones and dust. When the forearm 3 extends outward, the combined action of the first fixed pulley 51, the second fixed pulley 52, the steel rope 53, the third fixed pulley 54, and the fourth fixed pulley 55 drives the ear plate 58 and the U-shaped base plate 59 above it to move upward. At the same time, it drives the bottom of the accordion dust cover 57 to move upward, thus achieving the automatic retraction of the accordion dust cover 57. When the forearm 3 retracts, the weight of the U-shaped base plate 59 drives the accordion dust cover 57 to move downward, thus achieving the automatic retraction of the accordion dust cover 57. This facilitates close contact between the protective cover and the rock surface, thereby maximizing the control of flying stone debris.

[0025] Please see Figure 2 and Figure 5 The spraying mechanism 6 includes a U-shaped frame 64 fixedly connected to the bottom of the square clamp body 561. A connecting block 65 is fixedly installed at the bottom of the U-shaped frame 64. An atomizing nozzle 66 is fixedly installed at the bottom of the connecting block 65. A water supply hose 63 is fixedly installed at the input end of the atomizing nozzle 66. A water pump 62 is provided at the end of the water supply hose 63 away from the atomizing nozzle 66. The output end of the water pump 62 is connected to the water supply hose 63. A water tank 61 is fixedly connected to the input end of the water pump 62. Both the water tank 61 and the water pump 62 are installed on the excavator body 1.

[0026] When the equipment is crushed, the water pump 62 is started. The water pump 62 delivers the clean water stored in the water tank 61 to the atomizing nozzle 66 through the water delivery hose 63 for atomization and spraying, thereby achieving dust suppression by spraying.

[0027] It should be noted that, when using this accordion-style dust cover for a breaker cone, the square clamp body 561 is first fitted and fixed onto the breaker hammer 4. Then, the square clamp body 561 is tightly fixed onto the breaker hammer 4 using screws 563 and nuts 564. At this point, the protective mechanism 5 is installed, which is convenient for installation and disassembly. The accordion dust cover 57 in the protective mechanism 5 protects against flying stones and dust during breaker operation, effectively preventing the generation of dust and flying stones. The accordion dust cover 57 is U-shaped with its opening facing the excavator body 1 for easy viewing. The accordion dust cover 57 can automatically rise and fall according to the working angle of the breaker hammer 4, allowing the accordion dust cover 57 to be in close contact with the rock surface, thereby achieving the maximum effect of controlling stone debris splashing. During operation, the spraying mechanism 6 is used for dust suppression.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
