Description

Technical Field

[0001] This utility model belongs to the technical field of mining polishing machines, specifically referring to a mining direct-drive angle polishing machine. Background Technology

[0002] Compared with traditional angle grinders, direct-drive angle grinders have advantages such as low transmission loss, high working efficiency, high precision, small size, and light weight. They are convenient to be used in complex and confined working environments in mines. Since most spaces in mining operations are relatively enclosed and narrow, when using a grinder for grinding, a protective cover is needed to prevent the splashing of debris and dust, so as to avoid directly causing a high dust concentration in the space.

[0003] The protective covers of existing direct-drive angle grinders are mostly fixed to the grinder body with multiple sets of bolts. This results in a constant position where foreign objects can come into contact with the grinding wheel, making it inflexible in use and unable to adapt to the processing of corners and edges. The adjustment process is also very cumbersome. In addition, when existing grinders come into contact with objects during processing, they generate a lot of dust as the grinding wheel rotates. This not only affects the user's health but also increases potential risks in the relatively enclosed mining environment. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a mining direct-drive angle grinder, which effectively solves the problems of fixed and inconvenient adjustment of the protective cover of the existing direct-drive angle grinder, resulting in fixed cutting angle and insufficient flexibility. It also solves the problems of dust splashing during the grinding process, affecting human health and increasing dust in the space.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a mining direct-drive angle grinder, including an angle grinder body. A direct-drive motor is provided at the upper end of the angle grinder body, and a grinding wheel is keyed to the output end of the direct-drive motor. The grinding wheel is pressed against the output end shoulder by a pressure plate. The pressure plate is threaded to the output end of the direct-drive motor. It also includes an angle adjustment mechanism and a protective cover provided at the upper end of the angle grinder body. The angle adjustment mechanism consists of a limit slide rail, a limit slip ring, and a drive assembly. The limit slide rail is fixed to the outer wall of the upper end of the angle grinder body by bolts. The limit slip ring is fixed to the side wall of the protective cover and slidably connected to the limit slide rail. The drive assembly is provided on the angle grinder body and connected to the protective cover. It also includes a shell fixed to one side of the upper end of the angle grinder body, and a water spray dust suppression mechanism is provided on the angle grinder body. The water spray dust suppression mechanism includes a water spray panel fixed to the outer side of the upper end of the angle grinder body. A micro pump is provided inside the shell. At the same time, a water storage bottle is threaded to the outer side of the shell.

[0006] As an improvement to this solution, the drive assembly includes a fixing member that is fixed to the angle grinder body by bolts. A rotating shaft is rotatably connected to the fixing member and passes through the fixing member. A worm gear is fixed on the rotating shaft. A worm is rotatably connected to the inner wall of the fixing member. The worm is perpendicular to the rotating shaft and meshes with the worm gear.

[0007] As an improvement to this solution, cylindrical anti-slip handles are fixed to both ends of the worm gear through-fixing component.

[0008] As an improvement to this solution, an arc-shaped rack is fixed to the outer side of the protective cover, and a drive gear is fixed to the end of the rotating shaft through the fixing member near the protective cover, and the drive gear meshes with the arc-shaped rack.

[0009] As an improvement to this solution, the end of the micro pump near the main body of the angle grinder is connected to a water supply pipe, which passes through the main body of the angle grinder and connects to the water spray panel. The end of the micro pump away from the main body of the angle grinder is provided with a water suction pipe, which passes through the outer shell and is located inside the water storage bottle.

[0010] As an improvement to this solution, an operation switch is provided on the side wall of the angle grinder body, and a storage battery is provided inside the angle grinder body below the operation switch. At the same time, a wiring terminal is provided at the bottom of the angle grinder body, which can be connected to an external power source for use, and the storage battery can be used wirelessly.

[0011] As an improvement to this solution, a handle is vertically fixed on one side of the angle grinder body, and the handle is located below the water storage bottle. Furthermore, several anti-slip grooves are evenly distributed along the extension direction on the side wall of the angle grinder body.

[0012] The beneficial effects of this utility model by adopting the above structure are as follows:

[0013] 1. It is equipped with an angle adjustment mechanism connected to the protective cover, which can easily adjust the angle of the protective cover, thereby improving the flexibility of use, facilitating processing from different angles, and simplifying operation;

[0014] 2. Equipped with a water spray dust suppression mechanism, which reduces dust splashing during the grinding process by adding water mist to the grinding wheel area, avoiding dust density in small, enclosed spaces and improving safety during use. Attached Figure Description

[0022] The accompanying drawings are provided to further understand the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation thereof. Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 and Figure 4 As shown, the present invention proposes a mining direct-drive angle grinder, which includes an angle grinder body 1. A direct-drive motor 2 is provided at the upper end of the angle grinder body 1, and a grinding wheel 3 is keyed to the output end of the direct-drive motor 2. The grinding wheel 3 is pressed against the output end shoulder by a pressure plate 4, and the pressure plate 4 is threaded to the output end of the direct-drive motor 2.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, it also includes an angle adjustment mechanism 5 and a protective cover 6 located on the upper end of the angle grinder body 1. The angle adjustment mechanism 5 consists of a limit slide rail 7, a limit slip ring 8 and a drive assembly 9. The limit slide rail 7 is internally fixed to the outer wall of the upper end of the angle grinder body 1 by bolts. The limit slip ring 8 is fixed to the side wall of the protective cover 6 and slidably connected to the limit slide rail 7. The drive assembly 9 is located on the angle grinder body 1 and connected to the protective cover 6.

[0026] The protective cover 6 can rotate around the axis of the grinding wheel 3 via the limiting slide rail 7 and the limiting slip ring 8, and can be adjusted and fixed via the drive component 9.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a housing 10 fixed to one side of the upper end of the angle grinder body 1, and the angle grinder body 1 is provided with a water spray dust suppression mechanism 11. The water spray dust suppression mechanism 11 includes a water spray panel 12 fixed to the outer side of the upper end of the angle grinder body 1. A micro pump 13 is provided inside the housing 10. At the same time, a water storage bottle 14 is threadedly connected to the outer side of the housing 10.

[0028] The water in the water storage bottle 14 is sprayed out through the water spray panel 12 by the micro pump 13 to the grinding wheel 3 inside the protective cover 6, so that the dust during the polishing process mixes with the water mist and falls down under the action of gravity, avoiding splashing and scattering.

[0029] like Figure 5 and Figure 6 As shown, in order to adjust the angle of the protective cover 6, the drive assembly 9 includes a fixing member 15 fixed to the angle grinder body 1 by bolts. A rotating shaft 16 is rotatably connected to the fixing member 15 and passes through the fixing member 15. A worm gear 17 is fixed on the rotating shaft 16. A worm 18 is rotatably connected to the inner wall of the fixing member 15. The worm 18 is perpendicular to the rotating shaft 16 and meshes with the worm gear 17. Cylindrical anti-slip handles are fixed at both ends of the worm 18 that pass through the fixing member 15. An arc-shaped rack 19 is fixed to the outer side of the protective cover 6. A drive gear 20 is fixed to the end of the rotating shaft 16 that passes through the fixing member 15 near the protective cover 6 and meshes with the arc-shaped rack 19.

[0030] The angle of the protective cover 6 can be adjusted by rotating the worm gear 18. The operation is simple and convenient. Furthermore, the self-locking capability of the connection between the worm wheel 17 and the worm gear 18 ensures that the adjusted position of the protective cover 6 is fixed.

[0031] like Figure 2 As shown, the end of the micro pump 13 closest to the angle grinder body 1 is connected to a water supply pipe 21, and the water supply pipe 21 passes through the angle grinder body 1 and connects to the water spray panel 12. The end of the micro pump 13 furthest from the angle grinder body 1 is provided with a water suction pipe 22, and the water suction pipe 22 passes through the outer shell 10 and is located inside the water storage bottle 14.

[0032] The suction pipe 22 ensures that the micro pump 13 can draw water from the water storage bottle 14 when tilted, thus ensuring continuous water mist spraying.

[0033] like Figure 1 and Figure 2 As shown, an operation switch 23 is provided on the side wall of the angle grinder body 1, and a storage battery 24 is provided inside the angle grinder body 1 below the operation switch 23. At the same time, a wiring terminal 25 is provided at the bottom of the angle grinder body 1. An external power source can be connected through the wiring terminal 25, and the angle grinder can be used wirelessly by using the storage battery 24.

[0034] like Figure 4 As shown, a handle 26 is vertically fixed on one side of the angle grinder body 1, and the handle 26 is located below the water storage bottle 14. Furthermore, several anti-slip grooves are evenly distributed along the extension direction on the side wall of the angle grinder body 1.

[0035] In practical use, power is supplied by connecting an external power source via battery 24 or terminal 25. The direct drive motor 2 is activated via operation switch 23, causing the grinding wheel 3 to rotate. The user can bring the entire angle grinder close to the object to be polished by grasping the anti-slip groove and handle 26 on the main body 1. During grinding and cutting, the micro pump 13 is activated to send water from the water tank 14 through the water pipe 21 to the water spray panel 12, and then sprays it out through the nozzles on the outside of the water spray panel 12 to the area around the grinding wheel 3 in contact with the object. This causes the water mist to mix with the dust before falling. When the position of the protective cover 6 needs to be adjusted to adapt to different working conditions, simply rotate the worm gear 18 to rotate the worm wheel 17 that meshes with it. Driven by the worm wheel 17, the rotating shaft 16 rotates accordingly. The drive gear 20 located at one end of the rotating shaft 16 drives the arc rack 19 to rotate. At this time, the protective cover 6, which is fixedly connected to the arc rack 19, rotates along the limit slide rail 7 under the action of the limit slip ring 8, thereby realizing the adjustment of the position of the protective cover 6 and changing the open position of the protective cover 6 for suitability. The above is the entire usage process of the mining direct drive angle grinder.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
