When using them, a hydraulic system is required. Attention must be paid to oil line cleanliness and equipment maintenance. Operators must take precautions against vibration to ensure safe and efficient operation.

[0003] Hydraulic breakers commonly found on the market often lack a protective structure during the breaking process, causing debris and gravel to fly onto construction workers and potentially cause injury. This situation is especially dangerous in urban construction or in confined spaces. Utility Model Content

[0007] In a preferred embodiment of this utility model, a pushing assembly is provided on the opposite side of the mounting plate, and two pushing assemblies are provided, the two pushing assemblies comprising: Pushing component: The pushing component is fixedly connected to the opposite side of the mounting plate at one end, and the outer surface of the pushing component is slidably connected to the inner wall of the protective cover; First spring: The first spring is sleeved on the outer surface of the pusher, with one end of the first spring fixedly connected to the outer surface of the protective cover and the other end of the first spring fixedly connected to the outer surface of the pusher.

[0008] In a preferred embodiment of this utility model, a limiting component is provided on the upper side of the mounting plate, and two limiting components are provided, the two limiting components comprising: Limiting groove: The limiting groove is formed on the upper surface of the mounting plate; Limiting block: The outer surface of the limiting block is in contact with the inner wall of the limiting groove, and the limiting block passes through the lower surface of the hydraulic mechanism; Connecting column: The lower end face of the connecting column is fixedly connected to the upper surface of the limiting block.

[0012] 1. This utility model, by setting up an auxiliary protective mechanism, a pushing component, a limiting component, a telescopic component, a second sliding groove, and a clamping component, involves placing a protective cover over the outer surface of the hydraulic mechanism housing. Then, by pressing the pushing component, the pushing component can compress the first spring, causing it to generate elastic force. Simultaneously, the pushing component can compress the mounting plate. The mounting plate moves along the outer surface of the protective cover towards the mounting groove via the first sliding groove. The upper surface of the mounting plate can compress the limiting block, causing the limiting block to move the connecting column upwards. The connecting column can then compress the telescopic rod and the second spring via the pushing plate, causing the second spring to generate elastic force. When the limiting block aligns with the limiting groove, the second spring releases its elastic force, pushing the push plate downwards. The push plate, through the connecting column, moves the limiting block downwards, allowing it to enter the limiting groove and fit tightly against it. At this point, the mounting plate fits tightly against the mounting groove. Simultaneously, the push plate drives the fixing block, the clamping component, and the tension spring until the clamping component passes through the corresponding hole on the outer surface of the hydraulic mechanism. Then, the tension spring releases its tension, pulling the clamping component through the hole and fixing the push plate. This achieves the effect of preventing gravel and stone chips from splashing onto construction workers during crushing. Attached Figure Description

[0015] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0016] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] like Figures 1 to 5 As shown in the figure, an auxiliary structure for a hydraulic breaker provided in this embodiment of the present invention includes: Control handle 1; Hydraulic mechanism 2: Hydraulic mechanism 2 is fixedly connected to the lower surface of control handle 1; Crane 3: The upper end face of the crane 3 is fixedly connected to the inner wall of the hydraulic mechanism 2; Auxiliary protection mechanism 4: The auxiliary protection mechanism 4 is disposed on the outer surface of the breaker 3, and the auxiliary protection mechanism 4 includes: Protective pad 41: Protective pad 41 is installed on the outside of the breaker pick 3; Protective cover 42: The inner wall of the protective cover 42 is fixedly connected to the outer surface of the protective pad 41; Mounting component 43: Mounting component 43 is located inside the protective cover 42.

[0018] refer to Figure 3 As shown, installation component 43 includes: Mounting slot 431: Mounting slot 431 is formed on the outer surface of hydraulic mechanism 2; Mounting plate 432: Two mounting plates 432 are provided, and the opposite side of the two mounting plates 432 is in contact with the outer surface of the mounting groove 431. First slide groove 433: Four first slide grooves 433 are provided. The four first slide grooves 433 are opened on the outer surface of the mounting plate 432. The inner wall of the first slide groove 433 is slidably connected to the outer surface of the protective cover 42.

[0019] The above solution involves placing the protective cover 42 on the outer surface of the hydraulic mechanism 2 housing, and then moving the mounting plate 432 along the outer surface of the protective cover 42 towards the mounting groove 431 through the first sliding groove 433 until the mounting plate 432 and the mounting groove 431 are tightly fitted, thereby installing the protective cover 42 on the outer surface of the hydraulic mechanism 2. This effectively prevents broken stones from flying upwards. The protective pad 41 is made of transparent rubber, which mainly serves to cushion the flying stones. The protective cover 42 is made of transparent polycarbonate material.

[0020] refer to Figure 3 As shown, a pushing assembly 5 is provided on the opposite side of the mounting plate 432. There are two pushing assemblies 5, and the two pushing assemblies 5 include: Pushing component 51: One end of the pushing component 51 is fixedly connected to the opposite side of the mounting plate 432, and the outer surface of the pushing component 51 is slidably connected to the inner wall of the protective cover 42; First spring 52: The first spring 52 is sleeved on the outer surface of the pusher 51. One end of the first spring 52 is fixedly connected to the outer surface of the protective cover 42, and the other end of the first spring 52 is fixedly connected to the outer surface of the pusher 51.

[0021] The above solution is adopted: In order to move the mounting plate 432 closer to the mounting groove 431, the pushing member 51 is pressed, which can squeeze the first spring 52, so that the first spring 52 generates elastic force. At the same time, the pushing member 51 can squeeze the mounting plate 432, so that the mounting plate 432 moves, thereby driving the mounting plate 432.

[0022] refer to Figure 4 As shown, a limit component 6 is provided on the upper side of the mounting plate 432. There are two limit components 6, and the two limit components 6 include: Limiting groove 61: The limiting groove 61 is formed on the upper surface of the mounting plate 432; Limiting block 62: The outer surface of the limiting block 62 fits against the inner wall of the limiting groove 61, and the limiting block 62 passes through the lower surface of the hydraulic mechanism 2; Connecting post 63: The lower end face of the connecting post 63 is fixedly connected to the upper surface of the limiting block 62.

[0023] Using the above scheme: when the mounting plate 432 moves to the side of the mounting groove 431, the upper surface of the mounting plate 432 can press the limiting block 62, so that the limiting block 62 drives the connecting column 63 to move upward until the limiting block 62 corresponds to the limiting groove 61, so that the limiting block 62 can enter the limiting groove 61 and fit tightly with the limiting groove 61, thereby fixing the mounting plate 432.

[0024] refer to Figure 4 As shown, a telescopic component 7 is provided on the upper end face of the connecting column 63. The telescopic component 7 includes: Push plate 71: The lower surface of push plate 71 is fixedly connected to the upper end face of connecting column 63; Telescopic rod 72: Four telescopic rods 72 are provided, and the lower end faces of the four telescopic rods 72 are fixedly connected to the upper surface of the push plate 71; Second spring 73: Four second springs 73 are provided. The four second springs 73 are sleeved on the outer surface of the telescopic rod 72. The lower end face of the second spring 73 is fixedly connected to the upper surface of the push plate 71. Fixed plate 74: The lower surface of fixed plate 74 is fixedly connected to the upper end face of telescopic rod 72 and second spring 73, and the outer surface of fixed plate 74 is fixedly connected to the outer surface of hydraulic mechanism 2.

[0025] Using the above scheme: when the connecting column 63 moves upward, the connecting column 63 can squeeze the telescopic rod 72 and the second spring 73 through the push plate 71, so that the second spring 73 generates elastic force. When the limiting block 62 corresponds to the limiting groove 61, the second spring 73 can release the elastic force, pushing the push plate 71 to move downward. The push plate 71 drives the limiting block 62 to move downward through the connecting column 63.

[0026] refer to Figure 5 As shown, the hydraulic mechanism 2 has a second groove 8 on its outer surface, and the inner wall of the second groove 8 is slidably connected to the outer surface of the push plate 71.

[0027] Using the above scheme: the second slide 8 mainly serves to provide a moving path for the longitudinal movement of the push plate 71.

[0028] refer to Figure 5 As shown, a clamping assembly 9 is provided on the lower surface of the push plate 71. The clamping assembly 9 includes: Fixed block 91: The upper surface of fixed block 91 is fixedly connected to the lower surface of push plate 71; Clamping component 92: Clamping component 92 passes through the surface of fixed block 91 and hydraulic mechanism 2, and the outer surface of clamping component 92 is slidably connected to the inner wall of fixed block 91; Tension spring 93: Tension spring 93 is sleeved on the outer surface of clamping member 92, the front end face of tension spring 93 is fixedly connected to the rear surface of clamping member 92, and the rear end face of tension spring 93 is fixedly connected to the front surface of fixing block 91.

[0029] The above scheme is adopted: when the push plate 71 moves down, the push plate 71 can drive the fixing block 91, the clamping member 92 and the tension spring 93 until the clamping member 92 passes through the corresponding hole on the outer surface of the hydraulic mechanism 2. Then the tension spring 93 releases the tension, pulls the clamping member 92 through the hole, and realizes the function of fixing the push plate 71. Since the tension direction of the tension spring 93 is perpendicular to the surface of the hydraulic mechanism 2, its length is less than 1.5 times that in the free state, which avoids resonance and reduces the impact on the tension spring 93.

[0030] In use, the protective cover 42 is fitted onto the outer surface of the hydraulic mechanism 2 housing. Then, by pressing the pusher 51, the pusher 51 can compress the first spring 52, causing the first spring 52 to generate elastic force. At the same time, the pusher 51 can compress the mounting plate 432. The mounting plate 432 moves towards the mounting groove 431 along the outer surface of the protective cover 42 via the first sliding groove 433. The upper surface of the mounting plate 432 can compress the limiting block 62, causing the limiting block 62 to drive the connecting column 63 to move upward. The connecting column 63 can compress the telescopic rod 72 and the second spring 73 via the pusher 71, causing the second spring 73 to generate elastic force. When the limiting block 62 corresponds to the limiting groove 61, the second spring 73 can release its elastic force, pushing the push plate 71 to move downward. The push plate 71 drives the limiting block 62 to move downward through the connecting column 63, so that the limiting block 62 can enter the limiting groove 61 and fit tightly with the limiting groove 61. At this time, the mounting plate 432 fits tightly with the mounting groove 431. At the same time, the push plate 71 can drive the fixing block 91, the clamping member 92 and the tension spring 93 until the clamping member 92 passes through the hole on the outer surface of the hydraulic mechanism 2 and corresponds to it. Then the tension spring 93 releases its tension, pulls the clamping member 92 through the hole, and fixes the push plate 71. If the protective cover 42 needs to be removed, similarly, simply pull the clamping member 92 outwards, the clamping member 92 will leave the inner wall of the hydraulic mechanism 2, and then lift it upwards so that the limiting block 62 leaves the inside of the limiting groove 61, so that the first spring 52 can release its elastic force, so that the mounting plate 432 is not tightly attached to the mounting groove 431, and at this time the protective cover 42 can be removed.

[0031] In summary, this auxiliary structure for a hydraulic breaker, through the auxiliary protection mechanism 4, the pushing component 5, the limiting component 6, the telescopic component 7, the second sliding groove 8, and the clamping component 9, solves the problem that the stone chips and gravel generated during the break-out process may fly onto construction workers and cause injury due to the lack of a shielding structure. This situation is especially dangerous in urban construction or construction in confined spaces.
