Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to an anti-throwing-out mechanism for a drum-type ball mill. Background Art

[0002] A ball mill is a common grinding machine. A plurality of spheres are installed in its ball grinding tank. During operation, the ball grinding tank rotates, causing the spheres to rise and drop to crush and grind the materials. The patent with the application number 201821765193.X discloses a drum-type ball mill for preventing the ball grinding tank from being thrown out, including a frame. A first rotating shaft and a second rotating shaft are arranged at the upper end of the frame. A motor is fixed to the lower part of the frame through a support plate. The right end of the motor is connected with a first pulley through a motor shaft. The first pulley is connected with a second pulley through a belt. The second pulley is sleeved on the first rotating shaft. Two limiting shafts are symmetrically arranged at the upper end of the frame. The limiting shafts are respectively located on both sides of the first rotating shaft and the second rotating shaft. Limiting frames are fixedly arranged on the limiting shafts, so that the ball grinding tank can be effectively prevented from being thrown out under high-speed rotation without hindering the rotation of the ball grinding tank. However, the two limiting frames of the mechanism for preventing the ball grinding tank from being thrown out need to be separately pried open by two people, which is rather inconvenient. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide an anti-throwing-out mechanism for a drum-type ball mill in view of the above-mentioned existing technical deficiencies.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: an anti-throwing-out mechanism for a drum-type ball mill, including a frame, and further including a first limiting frame and a second limiting frame. A plurality of first limiting arms are arranged on the first limiting frame. A plurality of second limiting arms are arranged on the second limiting frame. Rollers are arranged at the tops of the first limiting arms and the second limiting arms. The lower end of the first limiting frame is rotationally connected to one side of the frame. The middle part of the second limiting frame is rotationally connected to the other side of the frame. A tail plate is arranged at the lower part of the second limiting frame. A pushing arm is arranged on one side of the second limiting frame. The end of the pushing arm far away from the second limiting frame is hinged to the middle part of the first limiting frame. A locking mechanism capable of locking the tail plate to fix the first limiting frame and the second limiting frame is arranged at the lower part of one side of the frame.

[0005] Preferably, the locking mechanism includes a left support seat and a right support seat. One end of a baffle is hinged to the top of the right support seat. A socket penetrating through the upper and lower sides of the baffle is arranged on the baffle. The socket also penetrates through the end of the baffle far away from the right support seat. A through groove is arranged at the upper end of the left support seat.

[0006] Preferably, one end of the baffle away from the right support seat is provided with an insertion hole penetrating through its front and rear sides, and the left support seat is also provided with an insertion hole, and the bolt can be inserted into the insertion holes on the baffle and the left support seat at the same time.

[0007] The beneficial effects of the present utility model are as follows: In the present utility model, the lower end of the first limiting frame is rotatably connected to one side of the frame, the middle part of the second limiting frame is rotatably connected to the other side of the frame, and the pushing arm on one side of the second limiting frame is hinged to the middle part of the first limiting frame. Thus, rotating the tail plate at the lower part of the second limiting frame can cause the two limiting frames to rotate together and their rotation directions are opposite, which is relatively convenient.

[0014] The following will clearly and completely describe the technical solutions of the present utility model in combination with specific embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0015] DETAILED DESCRIPTION OF THE EMBODIMENTS: In combination with Figures 1-4As shown in the figure, an anti-throwing mechanism for a drum ball mill includes a frame 1. Two rotating shafts are provided on the upper surface of the frame 1. One of the rotating shafts is in transmission connection with a motor. A ball mill tank 2 can be placed on the two rotating shafts and is thus driven to rotate by the rotating shafts. It also includes a first limiting frame 3 and a second limiting frame 4. A plurality of first limiting arms 31 are provided on the first limiting frame 3, and a plurality of second limiting arms 41 are provided on the second limiting frame 4. Rollers are provided at the tops of the first limiting arms 31 and the second limiting arms 41. The lower end of the first limiting frame 3 is rotatably connected to one side of the frame 1, and the middle of the second limiting frame 4 is rotatably connected to the other side of the frame 1. A tail plate 42 is provided at the lower part of the second limiting frame 4. A pushing arm 43 is provided at the middle and lower part of one side of the second limiting frame 4 (i.e., below the part where it is rotatably connected to the frame 1). The end of the pushing arm 43 away from the second limiting frame 4 is hinged to the middle of the first limiting frame 3. A locking mechanism capable of locking the tail plate 42 to fix the first limiting frame 3 and the second limiting frame 4 is provided at the lower part of one side of the frame 1. At this time, the rollers are in contact with the upper part of the outer circumference of the ball mill tank 2 or very close to the upper part of the outer circumference of the ball mill tank 2, so as to prevent the ball mill tank 2 from being thrown out.

[0016] In this embodiment, the locking mechanism includes a left support seat 6 and a right support seat 8. One end of a baffle 7 is hinged to the top of the right support seat 8. A socket is provided on the baffle 7 and penetrates through the upper and lower sides of the baffle 7. The socket also penetrates through the end of the baffle 7 away from the right support seat 8. A through groove is provided at the upper end of the left support seat 6, and the width of the through groove is equal to or slightly larger than the thickness of the baffle 7. The end of the baffle 7 away from the right support seat 8 can enter the through groove, so that this end of the baffle 7 cannot move back and forth.

[0017] In this embodiment, a jack is provided at the end of the baffle 7 away from the right support seat 8 and penetrates through the front and rear sides of the baffle 7. A jack is also provided on the left support seat 6. A pin 5 can be inserted into the jacks on the baffle 7 and the left support seat 6 at the same time. At this time, the end of the baffle 7 away from the right support seat 8 cannot be lifted upward, so it will not come out of the through groove.

[0018] Working principle: As shown in Figure 1 the figure, pushing the tail plate 42 towards the first limiting frame 3 can make the upper ends of the two limiting frames move outwards. Then, the ball mill tank 2 can be placed on the two rotating shafts. Then, pulling the tail plate 42 away from the first limiting frame 3 makes the rollers in contact with the upper part of the outer circumference of the ball mill tank 2 or very close to the upper part of the outer circumference of the ball mill tank 2. At this time, the tail plate 42 is in a vertical state. Then, rotate the baffle 7 counterclockwise so that the tail plate 42 is located in the socket and the tail plate 42 is located in the through groove. Then, insert the pin 5 into the jacks on the baffle 7 and the left support seat 6 at the same time. One person can push and pull the tail plate 42 in this application, which is relatively convenient.

[0019] In this article, specific embodiments are used to elaborate on the principles and implementation manners of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
