[0013] Preferably, the rotating assembly includes two driving mechanisms, which are respectively arranged on both sides of the base frame. The driving mechanism includes a connecting rod and a hydraulic rod. One end of the connecting rod is rotatably mounted on the frame, and the other end of the connecting rod is fixed to the base frame.

[0015] Preferably, a plurality of lining plates are evenly fixed on the inner side of the rotating cylinder, the middle positions of the lining plates protrude outward, and the material of the lining plates is rubber.

[0016] Preferably, a rectangular hole is provided in the middle of the lining plate, a plurality of sockets are provided on the outer side of the rotating cylinder, and each socket is aligned one-to-one with the plurality of rectangular holes, and a plug plate is slidably inserted inside the socket, and a guide ring is fixed on the opposite side of the two reference rings, and the two guide rings are coaxially arranged with the two reference rings respectively, and a guide groove is provided on the annular surface of the guide ring, and the guide groove includes a large arc groove and a small arc groove coaxially arranged with the guide ring, and the adjacent two ends of the large arc groove and the small arc groove are connected, and a plurality of cross bars slide together between the two guide grooves, and the plurality of plug plates are evenly divided into a plurality of groups, and each group of plug plates is respectively fixed to a plurality of cross bars.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] First, the eccentric weight component of the present invention is arranged at one side of one end of the drum, and the deadweight of the eccentric weight component can be adjusted. When the drum starts to rotate, the weight of the eccentric weight component is relatively small. When the drum is fully rotated, the weight of the eccentric weight component becomes larger. At this time, one side of the drum is biased, and the inertia of the side where the eccentric weight component is located becomes larger, thereby reducing the driving force of the motor, reducing the power of the motor, and realizing energy saving. That is, when the drum just rotates, the eccentric weight component does not participate in the work and does not increase the output torque of the motor. After the drum is fully rotated, one side of the drum with the eccentric weight component is biased, and the output torque of the motor is reduced by inertia, thereby reducing the power of the motor;

[0020] Second, a sliding plug is slidably inserted on the lining plate of the present invention. When the plug is located at one side of the bottom of the drum, the plug remains in an extended state. When the drum rotates upward, the grinding balls are driven by the plug, so that the grinding balls are not easy to fall. At the same time, when the drum rotates upward, the plug gradually retracts, so that the grinding balls fall as high as possible, thereby increasing the impact force of the grinding balls, improving the crushing effect, and achieving efficient crushing.

[0021] Thirdly, the lining plate of the present invention is made of rubber plate, and the plug plate is made of spring steel with a large yield limit. The grinding ball contacts the lining plate and the plug plate during the falling process. Both the lining plate and the plug plate can achieve a buffering effect, and the lining plate can also achieve shock absorption. During the rebound process of the plug plate, the lining plate can absorb the elastic potential energy of the plug plate. The lining plate is also a rubber plate, which is a good damping material, thereby achieving shock absorption, and shock absorption can also achieve noise reduction.

[0035] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention provides a high-efficiency, silent and energy-saving drum ball mill. The technical solution of the present invention is:

[0037] like Figures 1 to 10 As shown, the embodiment of the present invention provides a high-efficiency, silent and energy-saving drum ball mill, including a base frame 6, a frame 1, a ball mill assembly 21 and an eccentric weight assembly 2, wherein the ball mill assembly 21 includes a rotating cylinder 24, and both ends of the rotating cylinder 24 are fixed with an intermediate cylinder 27 coaxially arranged therewith;

[0038] Combined with Figure 1 and attached Figure 2 As shown, a supporting structure is provided inside the frame 1 to enable the rotating cylinder 24 to rotate inside the frame 1;

[0039] The above-mentioned supporting structure includes a fixed cylinder 22, both ends of which are fixed with reference rings 28, and the two reference rings 28 are rotatably mounted on two intermediate cylinders 27 respectively, and two positioning grooves 23 are provided on the outer side of the fixed cylinder 22, and support seats 9 are fixed at the four corners of the positioning grooves 23, and the fixed cylinder 22 is fixed in the frame 1 through the support seats 9.

[0040] From the above connection relationship, it can be known that the working principle of the supporting structure is: since the fixed cylinder 22 is fixed to the frame 1 through the support seat 9, it can be known that the fixed cylinder 22 is stationary relative to the frame 1, and since the two reference rings 28 are rotatably installed on the two intermediate cylinders 27 respectively, it can be known that the intermediate cylinders 27 at the two ends of the rotating cylinder 24 can rotate, that is, the rotating cylinder 24 fixed to the intermediate cylinder 27 can rotate in the fixed cylinder 22.

[0041] Combined with Figure 1 As shown, a driving assembly is provided on the outer side of the frame 1 to provide a rotational force for one of the intermediate cylinders 27;

[0042] The above-mentioned driving assembly includes a driving motor 11, and the driving motor 11 is fixed to the frame 1, wherein a second synchronous wheel 13 coaxially arranged therewith is fixed to the outer side of one of the intermediate cylinders 27, and a third synchronous wheel 10 coaxially arranged therewith is fixed to the output shaft of the driving motor 11, and the second synchronous wheel 13 and the third synchronous wheel 10 are jointly sleeved with a second synchronous belt 12.

[0043] From the above connection relationship, it can be known that the working principle of the driving assembly is: the driving motor 11 rotates the third synchronous wheel 10 through the output shaft, the second synchronous wheel 13 and the third synchronous wheel 10 rotate synchronously through the second synchronous belt 12, and the second synchronous wheel 13 drives the intermediate cylinder 27 fixed thereto to rotate, that is, the rotating cylinder 24 with the intermediate cylinder 27 rotates in the fixed cylinder 22.

[0044] Combined with Figure 2 As shown, a rotating assembly is provided on the top of the base frame 6 to enable the frame 1 to rotate at a certain angle;

[0045] The above-mentioned rotating assembly includes two driving mechanisms, which are respectively arranged on both sides of the base frame 6. The driving mechanism includes a connecting rod 7 and a hydraulic rod 8. One end of the connecting rod 7 is rotatably mounted on the frame 1, and the other end of the connecting rod 7 is fixed to the base frame 6. The two ends of the hydraulic rod 8 are respectively rotatably mounted on the frame 1 and the base frame 6.

[0046] From the above connection relationship, it can be known that the working principle of the driving assembly is: after the ball milling is completed, the hydraulic rod 8 is shortened, and at this time the frame 1 rotates downward to pour out the material in the rotating cylinder 24.

[0047] Combined with Figure 1 To Attachment Figure 4 As shown, the eccentric weight component 2 includes a hollow shell 17, and the hollow shell 17 is fixed to one of the intermediate cylinders 27, and one side of the hollow shell 17 protrudes outward, and a cover plate 18 is fixed at the shell opening of the hollow shell 17, and the outer shell of the cover plate 18 is provided with a rotating hole, and a fixing ring 16 is rotatably installed in the rotating hole through a bearing 20, and a fixing hole is provided on the outer side of the fixing ring 16, and a hollow tube 15 is fixed in the fixing hole, and a storage hopper 14 connected to the hollow tube 15 is fixed on the outer side of the hollow tube 15, and the storage hopper 14 is fixed to the frame 1, and steel balls are placed inside the storage hopper 14 (steel balls can replace other objects with higher density, such as lead sand), a circular hole is provided at one end of the hollow tube 15, and a shafted screw rod 19 is rotatably installed in the circular hole, and one end of the shafted screw rod 19 extends into the hollow shell 17, and a power component for rotating the shafted screw rod 19 is provided inside the frame 1;

[0048] Through the above connection relationship, it can be known that the working principle of the eccentric weight component 2 is: when the center tube rotates, the hollow shell 17 fixed with the center tube rotates accordingly. Since the fixed ring 16 is rotatably installed on the cover plate 18 through the bearing 20, it can be known that the fixed ring 16 can rotate relative to the hollow shell 17. At this time, the power component rotates the axial screw rod 19, and the axial screw rod 19 sends the steel balls of the storage hopper 14 into the hollow shell 17. At this time, one side of the drum is biased, and the inertia of the side where the eccentric weight component 2 is located becomes larger, thereby reducing the driving force of the motor, reducing the power of the motor, and realizing energy saving. That is, when the drum just rotates, the eccentric weight component 2 does not participate in the work and does not increase the output torque of the motor. After the drum is fully rotated, one side of the drum of the eccentric weight component 2 is biased, and with the help of inertia, the output torque of the motor is reduced, thereby reducing the power of the motor.

[0049] Combined with Figure 1 As shown, the power assembly includes a servo motor 3 and a transmission pair, and the transmission pair includes two first synchronous wheels 5 and a first synchronous belt 4. The two first synchronous wheels 5 are coaxially fixed to one end of the belt shaft screw rod 19 and the output shaft of the servo motor 3, and the first synchronous belt 4 is sleeved on the two first synchronous wheels 5;

[0050] From the above connection relationship, it can be known that the working principle of the power assembly is: the servo motor 3 rotates the first synchronous wheel 5 fixed to it through the output shaft, and the two first synchronous wheels 5 rotate synchronously through the first synchronous belt 4. Since the two first synchronous wheels 5 and the first synchronous belt 4 form a transmission pair, the output shaft of the servo motor 3 rotates the belt shaft screw rod 19 through the transmission pair.

[0051] Combined with Figure 5 and attached Figure 6 As shown, a plurality of lining plates 30 are evenly fixed on the inner side of the rotating cylinder 24, and the middle position of the lining plates 30 protrudes outwards. The material of the lining plates 30 is rubber;

[0052] From the above connection relationship, it can be known that the working principle of the lining 30 is: when the rotating drum 24 rotates, the middle position of the lining 30 moves the material, and the middle position of the lining 30 brings the grinding balls to a high place, so that the grinding balls fall from a high place to impact the material. Since the material of the lining 30 is rubber, the lining 30 can achieve shock absorption.

[0053] Combined with Figure 5 To Attachment Fig.10As shown, a rectangular hole is provided in the middle of the lining plate 30, a plurality of sockets are provided on the outer side of the rotating cylinder 24, and each socket is aligned with the plurality of rectangular holes one by one, and a plug plate 26 is slidably inserted inside the socket, a guide ring 29 is fixed on the opposite side of the two reference rings 28, and the two guide rings 29 are coaxially arranged with the two reference rings 28, respectively, and a guide groove is provided on the annular surface of the guide ring 29, and the guide groove includes a large arc groove 31 and a small arc groove 32 coaxially arranged with the guide ring 29, and the adjacent two ends of the large arc groove 31 and the small arc groove 32 are connected, and a plurality of cross bars 25 are slidably provided between the two guide grooves, and the plurality of plug plates 26 are evenly divided into a plurality of groups, and each group of plug plates 26 is respectively fixed with a plurality of cross bars 25;

[0054] From the above connection relationship, it can be known that the working principle of the plug board 26 is: Figure 7 For example, when the rotating cylinder 24 rotates counterclockwise, the insert plate 26 on the right side of the rotating cylinder 24 remains in an extended state, and the cross bar 25 fixed to the insert plate 26 moves in the small arc groove 32 in the guide groove, and the grinding balls are driven by the insert plate 26, so that the grinding balls are not easy to fall, and the grinding balls are made to fall as high as possible, thereby increasing the impact force of the grinding balls, improving the crushing effect, and achieving efficient crushing. When the cross bar 25 enters the large arc groove 31, the insert plate 26 is pulled back, so that the protrusion of the lining plate 30 can smoothly stir the material;

[0055] To supplement the above: there is no need to keep the insert plate 26 in the extended state at all times, because the insert plate 26 is at the bottom of the rotating cylinder 24, which makes it difficult for the material to be quickly stirred. At the same time, the grinding balls at the bottom will be blocked by the insert plate 26, and it is not easy for the grinding balls to collide with each other, making it difficult to crush the material.

[0056] Combined with Fig.10 As shown, a plurality of guide sleeves 33 are fixed in the rectangular opening of the lining plate 30, and each two adjacent guide sleeves 33 do not touch each other, and the inserting plate 26 is inserted into the guide sleeves 33;

[0057] Through the above connection relationship, it can be known that the working principle of the lining plate 30 is as follows: the guide sleeve 33 is set as an intermediate piece, and a material with high hardness and poor thermal conductivity is selected. It is difficult for the plug plate 26 to be damaged by friction with the lining plate 30, thereby improving the practical life of the lining plate 30. At the same time, the plug plate 26 can bend and deform inside the lining plate 30. The grinding ball contacts the lining plate 30 and the plug plate 26 during the falling process. The lining plate 30 and the plug plate 26 can both achieve a buffering effect, and the lining plate 30 can also achieve shock absorption. When the plug plate 26 is able to rebound, the lining plate 30 can absorb the elastic potential energy of the plug plate 26. The lining plate 30 is also a rubber plate, which is a good damping material, thereby achieving shock absorption, and shock absorption can also achieve noise reduction.

[0058] Working principle of rolling ball mill:

[0059] Put the grinding balls and the materials into the rotating cylinder 24, start the driving motor 11, the driving motor 11 rotates the third synchronous wheel 10 through the output shaft, the second synchronous wheel 13 and the third synchronous wheel 10 rotate synchronously through the second synchronous belt 12, the second synchronous wheel 13 drives the intermediate cylinder 27 fixed thereto to rotate, that is, the rotating cylinder 24 with the intermediate cylinder 27 rotates in the fixed cylinder 22, the lining plate 30 drives the materials to be turned and stirred, and at the same time, the protrusion of the lining plate 30 brings the grinding balls to a higher place, so that the grinding balls fall from a higher place;

[0060] by Figure 7 For example, when the rotating cylinder 24 rotates counterclockwise, the insert plate 26 on the right side of the rotating cylinder 24 remains in an extended state, and the cross bar 25 fixed to the insert plate 26 moves in the small arc groove 32 in the guide groove, and the grinding balls are driven by the insert plate 26, so that the grinding balls are not easy to fall, and the grinding balls are made to fall as high as possible, thereby increasing the impact force of the grinding balls, improving the crushing effect, and achieving efficient crushing. When the cross bar 25 enters the large arc groove 31, the insert plate 26 is pulled back, so that the protrusion of the lining plate 30 can smoothly stir the material;

[0061] Start the servo motor 3. When the center cylinder rotates, the hollow shell 17 fixed with the center cylinder rotates accordingly. Since the fixing ring 16 is rotatably mounted on the cover plate 18 through the bearing 20, it can be seen that the fixing ring 16 can rotate relative to the hollow shell 17. The servo motor 3 rotates the first synchronous wheel 5 fixed thereto through the output shaft. The two first synchronous wheels 5 rotate synchronously through the first synchronous belt 4. Since the two first synchronous wheels 5 and the first synchronous belt 4 form a transmission pair, that is, the output shaft of the servo motor 3 rotates the belt-shaft screw rod 19 through the transmission pair, the belt-shaft screw rod 19 delivers the steel balls of the storage hopper 14 into the hollow shell 17. At this time, one side of the drum is unbalanced, and the inertia of the side where the unbalanced weight component 2 is located becomes larger, thereby reducing the driving force of the motor and reducing the power of the motor.

[0062] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
