[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4 As shown, in the present embodiment, a bevel gear transmission device for a grinding mill comprises a shell 1, an inner shell 4 is arranged inside the shell 1, a bevel gear transmission mechanism is arranged inside the inner shell 4, a mounting groove 8 extending to the inside of the inner shell 4 is opened on the outer wall of the shell 1, an inner cavity bottom wall of the mounting groove 8 is opened with an oil dripping hole 10 extending to the inner wall of the inner shell 4, a lubrication mechanism is arranged in the mounting groove 8, the lubrication mechanism consists of a storage box 9, a movable rod 13, a sealing plate 16 and an oil dripping nozzle 17, the storage box 9 is slidably fitted with the mounting groove 8, an oil dripping nozzle 17 is arranged at the bottom of the storage box 9, the oil dripping nozzle 17 is in a connected state with the inside of the storage box 9, the oil dripping nozzle 17 is slidably fitted with the oil dripping hole 10, a sealing plate 16 is slidably installed inside the storage box 9, the upper end of the sealing plate 16 is fixedly connected with the movable rod 13, the upper end of the movable rod 13 slides through the top wall of the storage box 9, and the upper end of the storage box 9 is provided with an adjustment mechanism acting on the movable rod 13.

[0021] The bevel gear transmission mechanism consists of a motor 2, a transmission bevel gear 3 and a rotating shaft 5. The rear end of the shell 1 is fixedly connected to the motor 2, and the rotating shaft 5 is arranged inside the inner shell 4. The rear end of the rotating shaft 5 is fixedly connected to the output shaft of the motor 2, and the front end of the rotating shaft 5 is fixedly connected to the transmission bevel gear 3. The outer surface of the rotating shaft 5 is respectively provided with a front bearing 6 and a rear bearing 7, and the front bearing 6 and the rear bearing 7 are distributed at the front and rear ends of the rotating shaft 5. The inner wall of the inner shell 4 is provided with a receiving groove for accommodating the front bearing 6 and the rear bearing 7.

[0022] The transmission bevel gear 3 can be driven to rotate by the motor 2 , and the front bearing 6 and the rear bearing 7 can make the transmission bevel gear 3 rotate more stably.

[0023] Among them, the adjustment mechanism is composed of a U-shaped plate 12, an adjusting screw 14 and a rotating part 15. The U-shaped plate 12 is fixedly installed on the upper end of the storage box 9. The upper end of the U-shaped plate 12 is rotatably connected to the rotating part 15. The bottom of the U-shaped plate 12 is rotatably connected to the adjusting screw 14. The rotating part 15 is fixedly connected to the adjusting screw 14. The lower end of the adjusting screw 14 is inserted into the inside of the movable rod 13 and is connected to the movable rod 13 through threaded cooperation.

[0024] When in use, the rotating part 15 is rotated to drive the adjusting screw 14 to rotate, thereby controlling the movable rod 13 to move up and down, and then controlling the sealing plate 16 to move synchronously. The setting of the adjusting mechanism can prevent the movable rod 13 from being accidentally touched, which may cause the lubricating oil inside the storage box 9 to be completely used up, thereby protecting the lubricating oil. At the same time, rotating the adjusting screw 14 can move the sealing plate 16 more finely than directly moving the movable rod 13 up and down.

[0025] A plurality of anti-slip slots are provided on the side wall of the rotating member 15 .

[0026] The friction between the worker's hand and the rotating member 15 can be increased by providing a plurality of anti-slip grooves.

[0027] A fixing plate 11 is disposed at the opening of the mounting groove 8 .

[0028] When the storage box 9 is installed in the installation groove 8 , the upper end of the storage box 9 can be limited by the fixing plate 11 .

[0029] The utility model provides a bevel gear transmission device for a grinding mill, and the specific working principle is as follows:

[0030] When in use, the sealing plate 16 can be pushed to the bottom of the inner cavity of the storage box 9 to exclude the air inside the storage box 9, and then the oil drip nozzle 17 is inserted into the lubricating oil, and the movable rod 13 is pulled upward to draw the lubricating oil into the interior of the storage box 9. Since the interior of the storage box 9 is under negative pressure, the lubricating oil inside the storage box 9 will not drip out from the oil drip nozzle 17. The storage box 9 is installed in the installation groove 8, and the oil drip nozzle 17 is inserted into the oil drip hole 10. When the bevel gear transmission mechanism needs to be lubricated, it is only necessary to press the movable rod 13 downward to drip the lubricating oil in the storage box 9 into the interior of the inner shell 4, thereby lubricating the bevel gear transmission mechanism, which can make the lubrication work more efficient and quick. The lubricating oil in the storage box 9 is sufficient to lubricate the bevel gear transmission mechanism several times. At the same time, through the provided adjustment mechanism, it is possible to prevent the movable rod 13 from being accidentally touched, which may cause the lubricating oil inside the storage box 9 to be completely used up, thereby protecting the lubricating oil.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
