Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, in particular to an efficient feeding device for a ball mill. Background Art

[0002] A ball mill is a key device for further pulverizing materials after being crushed, and is mainly applied to production industries such as cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, and glass ceramics. According to different discharge methods, ball mills can be divided into two types: lattice type and overflow type, and can be divided into two grinding methods: dry type and wet type, which are suitable for grinding various ores and other materials, and are widely used in industries such as beneficiation, building materials, and chemical engineering.

[0003] Currently, for the ball mills on the market, after feeding, workers need to close the feeding port of the ball mill to prevent dust from flying during the grinding process. However, the current feeding port needs to be closed with multiple bolts, which is too troublesome and affects the feeding speed. Summary of the Utility Model

[0004] The utility model provides an efficient feeding device for a ball mill.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0006] An efficient feeding device for a ball mill includes a ball mill main body. A feeding port is formed in the top surface of the ball mill main body. A sliding groove is arranged on one side of the feeding port. A connecting plate is slidably installed in the sliding groove. A transmission rack is arranged on the top surface of the connecting plate. Fixed plates are fixedly installed on both sides of the middle of the sliding groove. A transmission gear is rotatably installed between the two fixed plates. The teeth on the transmission gear cooperate with the teeth on the transmission rack. A motor is arranged on one side of the sliding groove. The output shaft of the motor passes through the fixed plate and is fixedly connected to the middle of the transmission gear. One end of the connecting plate is connected to a cover plate.

[0007] A further preferred scheme of the utility model: The feeding port is rectangular, and an installation groove is arranged outside the feeding port, which is matched with the cover plate.

[0008] A further preferred scheme of the utility model: The motor is fixedly installed on the top surface of the ball mill main body, and the center point of the output shaft of the motor and the center point of the transmission gear are on the same horizontal plane.

[0009] A further preferred scheme of the utility model: The distance between the sliding groove and the feeding port is greater than the length of the cover plate.

[0010] The utility model has the following beneficial effects:

[0011] The utility model drives a transmission gear to rotate through a motor, thereby controlling a connecting plate to drive a cover plate to close a feed inlet, solving the problem of troublesome closing of the feed inlet, improving the feeding speed, and reducing the labor intensity. Brief Description of the Drawings

[0012] Figure 1 is a front view structural schematic diagram of the utility model;

[0013] In the figure: 1 ball mill main body, 2 feed inlet, 3 installation groove, 4 cover plate, 5 sliding groove, 6 connecting plate, 7 transmission rack, 8 fixing plate, 9 transmission gear, 10 motor. Specific Embodiments

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0015] According to Figure 1 As shown, a high-efficiency feeding device for a ball mill includes a ball mill main body 1. A feed inlet 2 is opened on the top surface of the ball mill main body 1. A sliding groove 5 is arranged on one side of the feed inlet 2. A connecting plate 6 is slidably installed in the sliding groove 5. A transmission rack 7 is arranged on the top surface of the connecting plate 6. Fixing plates 8 are fixedly installed on both sides in the middle of the sliding groove 5. A transmission gear 9 is rotatably installed between the two fixing plates 8. The teeth on the transmission gear 9 cooperate with the teeth on the transmission rack 7. A motor 10 is arranged on one side of the sliding groove 5. The output shaft of the motor 10 passes through the fixing plate 8 and is fixedly connected to the middle of the transmission gear 9. One end of the connecting plate 6 is connected to the cover plate 4.

[0016] The feed inlet 2 is rectangular. An installation groove 3 is arranged outside the feed inlet 2. The installation groove 3 cooperates with the cover plate 4. Such a setting can ensure the sealing performance at the feed inlet 2.

[0017] The motor 10 is fixedly installed on the top surface of the ball mill main body 1. The center point of the output shaft of the motor 10 and the center point of the transmission gear 9 are on the same horizontal plane. The motor 10 used in this device is a forward and reverse motor with a self-locking function.

[0018] The distance between the sliding groove 5 and the feed inlet 2 is greater than the length of the cover plate 4. Such a setting can make feeding more convenient.

[0019] Working principle: When feeding is required, the motor 10 rotates forward. The motor 10 drives the transmission gear 9 to rotate, and the transmission gear 9 controls the transmission rack 7 to drive, thereby controlling the connecting plate 6 to drive the cover plate 4 to move in the chute 5. The cover plate 4 is separated from the installation groove 3, and feeding can be carried out. On the contrary, after the feeding is completed, the motor 10 rotates reversely. The motor 10 drives the transmission gear 9 to rotate, and the transmission gear 9 controls the transmission rack 7 to drive, thereby controlling the connecting plate 6 to drive the cover plate 4 to move in the chute 5. The cover plate 4 enters the installation groove 3 to seal the feed inlet 2.

[0020] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
