Description

Technical Field

[0001] This utility model relates to the technical field of stone splash prevention devices, specifically to a stone splash prevention device for a gun head. Background Technology

[0002] At construction sites, when road breaker barrels break up road surfaces, stones and dust often fly up. The flying stones can easily harm the surrounding environment and construction workers, posing a safety hazard.

[0003] Existing anti-splash devices for blasting heads prevent debris from splashing during blasting by enclosing the blasting head around its perimeter. While this method can prevent debris from splashing, the semi-enclosed device hinders the blasting head's heat dissipation during long-term operation. This can easily lead to excessively high operating temperatures, causing the hydraulic oil to oxidize too quickly, the high-pressure oil seals inside the blasting head to fail, and key components to wear and age, severely damaging the blasting head and resulting in a short service life.

A flange 1 is installed at the bottom of the connecting cylinder 2. An arc-shaped cover 9 is connected to the bottom of the flange 1 via a mounting plate 7. A through groove 13 is provided at the center of the top of the connecting cylinder 2, the flange 1, and the mounting plate 7. A wear-resistant rubber strip 15 is arranged around the top of the connecting cylinder 2 around the through groove 13 to prevent direct contact between the top of the blasting head and the connecting cylinder 2, thus avoiding wear caused by the blasting head. A partition 16 is arranged around the through groove 13 inside the connecting cylinder 2. A ventilation plate 4 is fixed between the partitions 16, which limits and fixes the ventilation plate 4. Furthermore, it can increase the vertical load-bearing capacity of the connecting cylinder 2. The ventilation plate 4 is provided with a ventilation groove 3 on the outside, and a honeycomb heat dissipation plate 5 is arranged on the outside of the ventilation groove 3. The honeycomb heat dissipation plate 5 is evenly distributed with through holes 6 around the outer wall of the connecting cylinder 2. Through the design of the ventilation plate 4 and the ventilation groove 3, the airflow channel around the gun head can be effectively guaranteed, and the cold air from the outside will come into full contact with the gun head. With the design of the honeycomb heat dissipation plate 5 and the through holes 6, the heat around the gun head can be discharged, realizing the self-heating of the gun head when the device is working. It can effectively avoid the problem of excessively fast oxidation of hydraulic oil and ensure the service life of the gun head.

[0026] like Figures 1-4 As shown, in this embodiment, four extension plates 12 are installed at the four corners of the top of the connecting cylinder 2. Pull rings 14 are provided on the extension plates 12. The inner wall of the arc-shaped cover 9 is provided with high-strength wear-resistant steel plates 11. One end of the outer wall of the high-strength wear-resistant steel plate 11 is connected with wear-resistant rubber 10, and the other end of the outer wall of the high-strength wear-resistant steel plate 11 is provided with a polyurethane liner 8.

[0027] like Figures 1-4 As shown, in this embodiment, the extension plate 12 is screwed to the connecting cylinder 2, the pull ring 14 passes through the extension plate 12, and the high-strength wear-resistant steel plate 11 is connected to the arc-shaped cover 9 through the slot. The design of the extension plate 12 in conjunction with the pull ring 14 facilitates the hoisting of the entire device.

[0028] like Figures 1-4 As shown, in this embodiment, both the wear-resistant rubber 10 and the polyurethane liner 8 are bonded to the high-strength wear-resistant steel plate 11. The polyurethane liner 8 is arranged at one end close to the mounting plate 7. The polyurethane liner 8 has good wear resistance and does not require frequent replacement and maintenance. Combined with the design of the high-strength wear-resistant steel plate 11 and the wear-resistant rubber 10, it can effectively prevent flying gravel from damaging the arc-shaped cover 9.

[0029] like Figures 1-4 As shown, in this embodiment, flange 1 is screwed to connecting cylinder 2, and arc cover 9 is flanged to flange 1. The design of flange 1 facilitates the installation or removal of mounting plate 7 at any time, so as to facilitate the maintenance or replacement of arc cover 9.

[0030] like Figures 1-4 As shown, in this embodiment, the wear-resistant rubber strip 15 is bonded to the connecting cylinder 2, the partition 16 is connected to the through hole 6 in a slot, and the ventilation plate 4 is inserted into the partition 16. The design of the wear-resistant rubber strip 15 can prevent the gun head from wearing around the top of the through hole 6.

[0031] like Figures 1-4 As shown, in this embodiment, the honeycomb heat sink 5 is bonded to the connecting cylinder 2, and the through hole 6 is formed on the connecting cylinder 2. The honeycomb heat sink 5 can ensure the heat dissipation of the connecting cylinder 2 while having low density and excellent strength. Compared with traditional materials, the honeycomb heat sink 5 can effectively reduce the weight of the connecting cylinder 2 while maintaining the strength of the connecting cylinder 2, and effectively improve the overall performance of the connecting cylinder 2.

[0032] like Figures 1-4 As shown, in this embodiment, the mounting plate 7 is connected to the arc-shaped cover 9 with screws. The arc-shaped cover 9 has a structure that is narrow at the top and wide at the bottom. The mounting plate 7 realizes the installation limit of the arc-shaped cover 9. The design of the arc-shaped cover 9 can accurately block the falling of multiple flying stones.

[0033] The specific implementation process of this embodiment is as follows: When using the device, the gun head is inserted into the through groove 13, and the steel cable passes through the pull ring 14 of the extension plate 12. The top of the steel cable is fixed to the mechanical arm of the gun, realizing the quick installation and suspension of the device. The arc cover 9 provides protection for the gun head around its circumference. With the design of high-strength wear-resistant steel plate 11 and wear-resistant rubber 10, when the gun head is working, the flying gravel will come into contact with them and be blocked, which can effectively prevent the flying gravel from injuring people. At the same time, it can effectively reduce the noise of gravel rebound. With the design of ventilation plate 4, ventilation groove 3 and through hole 6, the air around the gun head can be circulated when the gun head is working for a long time, avoiding heat accumulation and damage to the gun head. At the same time, the design of honeycomb heat dissipation plate 5 can effectively improve the stability of the connecting cylinder 2 structure while ensuring heat circulation.
