Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a ball mill that facilitates feeding, including a feeding hopper 1, the bottom end of which is vertically inserted through the top end of a feeding channel 2, a conveying mechanism 3 is rotatably connected to one side of the outer wall of the feeding channel 2, a stirring mechanism 4 is provided at one end of the conveying mechanism 3, the tail end of the conveying mechanism 3 is transversely inserted through one side of the outer wall of a grinding cylinder 5, a discharge channel 6 is provided on one side of the bottom of the grinding cylinder 5, guide plates 7 are rotatably connected to the inner walls on both sides of the discharge channel 6, and grinding balls 8 are placed on the inner wall of the grinding cylinder 5.

[0021] In this embodiment, as Figure 1 and Figure 2 and Figure 3As shown, a vibrating motor 101 is screwed onto the outer wall of the bottom end of the feed hopper 1. It should be noted that the operator can first pour the raw material into the feed hopper 1 through the top opening and simultaneously start the two vibrating motors 101 on the outer wall of the bottom end. This causes the vibrating motors 101 to generate a vibration frequency, which in turn causes the entire feed hopper 1, screwed to them, to begin vibrating. Simultaneously, the raw material inside the feed hopper 1 will be rapidly shaken off by the large vibrations and fall into the bottom channel of the feed hopper 1, then flow along the channel into the feed channel 2 directly below for material transport. In actual use, the vibration... The vibration of motor 101 keeps the raw material flowing in the feed hopper 1, preventing it from accumulating or clogging, thus ensuring smooth feeding. The vibration of motor 101 also ensures the raw material is evenly distributed in the feed hopper 1, preventing segregation or stratification, thus guaranteeing feeding uniformity. Furthermore, the vibration of motor 101 accelerates the feeding speed, improving the ball mill's production efficiency. Additionally, the vibration of motor 101 enables automatic feeding of the raw material in the feed hopper 1, reducing manual operation and thus lowering labor intensity.

[0022] In this embodiment, as Figure 2 and Figure 3 As shown, the feeding mechanism 3 includes a servo motor 301 and a screw conveyor 302. The output end of the servo motor 301 is connected to the screw conveyor 302, and the end of the screw conveyor 302 near the servo motor 301 is rotatably connected to the outer wall of one side of the feeding channel 2. It should be noted that when the raw material enters the feeding channel 2 through the feeding hopper 1, the operator can simultaneously start the servo motor 301, causing the output end of the servo motor 301 to start rotating, which in turn drives the screw conveyor 302 connected to it to rotate. This allows the raw material entering the feeding channel 2 to be laterally pushed by the rotating screw conveyor 302 to the end of the feeding channel 2 until the raw material is conveyed into the grinding cylinder 5 for grinding. In actual use, the feeding mechanism 3... The mechanism 3 enables automated feeding, which significantly improves feeding speed and efficiency compared to manual feeding. The rotation of the screw conveyor 302 quickly transports the raw material into the grinding cylinder 5, reducing feeding time and increasing production efficiency. The rotating screw conveyor 302 also ensures that the raw material is evenly distributed within the feeding channel 2, gradually pushing it to the end of the channel and preventing accumulation and blockage, thus improving the final grinding effect. Furthermore, by adjusting the speed of the servo motor 301, the rotation speed of the screw conveyor 302 can be precisely controlled, allowing for flexible adjustment of the feeding amount and speed to meet different production needs, thereby improving product quality and production stability.

[0023] In this embodiment, as Figure 3As shown, a cutting ring is sleeved on the outer wall of the spiral conveyor 302 near the grinding cylinder 5. It should be noted that when the operator starts the servo motor 301 to rotate the spiral conveyor 302, the cutting ring sleeved on the outer wall of one end of the spiral conveyor 302 will also rotate along with it. During this time, the raw material will be laterally pushed by the rotating spiral conveyor 302 to the end of the feed channel 2, thus coming into contact with the cutting ring. When the raw material passes the cutting ring, it will be rotated and cut into small, loose pieces, facilitating the continued smooth conveying of the raw material to the grinding cylinder 5 on one side for grinding. In actual use, the rotational motion of the cutting ring can cut large pieces of raw material entering the feed channel 2 into smaller pieces, making them easier to be conveyed to the inside of the grinding cylinder 5 by the screw conveyor 302. This avoids large pieces of raw material blocking the outlet end of the feed channel 2. Furthermore, cutting the raw material into smaller pieces by the cutting ring helps to improve the uniformity of the feed, thereby ensuring that the grinding balls 8 and the raw material in the grinding cylinder 5 can make more full contact, improving the grinding effect. At the same time, the cutting ring can better disperse the raw material, helping to prevent the raw material from accumulating in a certain area of ​​the grinding cylinder 5, reducing the mutual adhesion between the raw materials, and allowing the raw material to be conveyed and ground more smoothly.

[0024] In this embodiment, as Figure 2 and Figure 3As shown, the stirring mechanism 4 includes a stirring shaft 401 and stirring rods 402. One end of the stirring shaft 401 is welded to the tail end of the spiral conveyor 302, and the stirring rods 402 are sleeved on the outer wall of the stirring shaft 401. The inner wall of the grinding cylinder 5 is provided with a liner 501, and the feed channel 2 and the grinding cylinder 5 are inclined at 15°. It should be noted that when the operator starts the servo motor 301 to drive the spiral conveyor 302 to rotate, the stirring shaft 401 welded to the tail end of the spiral conveyor 302 and several stirring rods 402 sleeved on the outer wall of the stirring shaft 401 can be driven to rotate together. This allows the stirring rods 402 to rotate and stir the raw materials and grinding balls 8 inside the grinding cylinder 5, thereby achieving the grinding operation. In actual use, the rotation of the stirring shaft 401 and stirring rods 402 can make the raw materials and grinding balls 8 fully mix and contact within the grinding cylinder 5, accelerating the grinding process and improving grinding efficiency. The speed is increased by the stirring action of the stirring mechanism 4. The material can be evenly distributed in the grinding cylinder 5, avoiding insufficient grinding in certain areas and ensuring the uniformity of grinding. The continuous stirring of the stirring mechanism 4 can prevent the raw material from accumulating in the grinding cylinder 5, keeping the raw material in a flowing state, which is conducive to grinding. At the same time, the rotation of the stirring rod 402 can drive the grinding balls 8 to move, increasing the frequency and force of the collision between the grinding balls 8 and the raw material, improving the grinding effect. The feeding channel 2 and the grinding cylinder 5 are set at a 15° inclination, which can use gravity to make the material slide down the feeding channel 2 more quickly and smoothly enter the grinding cylinder 5, reducing the possibility of material blockage. The inclined grinding cylinder 5 can make it easier for the ground material to be discharged from the discharge channel 6, reducing material residue and cleaning work. Meanwhile, the single spliced ​​liner 501 fixed by bolts can preferentially avoid direct contact between the grinding balls 8 and the raw material, thereby protecting the inner wall of the grinding cylinder 5 from scratches. At the same time, the liner 501 can also absorb and reduce the vibration and impact generated during the grinding process to a certain extent.

[0025] In this embodiment, as Figure 3As shown, a screen 601 is provided at the top opening of the discharge channel 6. It should be noted that when the operator starts the servo motor 301 to drive the screw conveyor 302 to rotate, the stirring mechanism 4 welded to the tail end of the screw conveyor 302 will also rotate and stir the raw material and grinding balls 8 inside the grinding cylinder 5, thus performing the grinding operation. During this process, the screen 601 prevents the grinding balls 8 from leaking out from the top opening of the discharge channel 6. After the grinding operation is completed, the operator can open the solenoid valve. This allows the ground material in the grinding cylinder 5 to pass through the screen 601 and be discharged outward along the discharge channel 6. In actual use, the screen 601 can effectively prevent the grinding balls 8 from leaking outward from the top opening of the discharge channel 6, avoiding the loss of the grinding balls 8 and damage to the equipment. The screen 601 can also make the raw material and grinding balls 8 in the grinding cylinder 5 fully mixed, improving grinding efficiency and reducing grinding time. At the same time, the screen 601 can screen the ground raw material, allowing only qualified particles to be discharged through the discharge channel 6, thereby ensuring product quality.

[0026] In this embodiment, as Figure 4 As shown, the guide plate 7 includes a rotating rod 701, an electric telescopic rod 702, and a plate body 703. The two ends of the rotating rod 701 are rotatably connected to the inner walls of both sides of the discharge channel 6. The plate body 703 is sleeved on the outer wall of the rotating rod 701. The driving end of the electric telescopic rod 702 is screwed to one side of the bottom of the plate body 703, and the tail end of the electric telescopic rod 702 is screwed to the inner walls of the left and right sides of the discharge channel 6. It should be noted that when the operator opens the solenoid valve, the ground material in the grinding cylinder 5 will enter the discharge channel 6. At this time, the material can fall downwards along the discharge channel 6 to the guide plate 7. Simultaneously, the operator can activate the electric telescopic rods 702 on both sides via an external controller, causing their driving ends to drive one side of the two plate bodies 703 screwed to them to perform a lifting operation. At the same time, the other side of the plate body 703... The rotating rod 701 rotates along with the lifting and lowering of one side of the plate 703, thereby opening and closing the left and right plates 703. This allows the raw material to slide down the plate 703 to the outlet of the discharge channel 6 directly below. In actual use, driven by the electric telescopic rod 702, the two plates 703 can automatically rotate and open, thereby controlling the flow direction of the raw material and ensuring that it falls accurately into the outlet of the discharge channel 6. This improves the accuracy and stability of the discharge. Furthermore, the guide plate 7 allows the raw material to flow in the discharge channel 6 in the optimal direction, thus preventing the raw material from accumulating and clogging the discharge channel 6. This, in turn, helps to improve discharge efficiency and equipment lifespan. At the same time, the opening and closing angle of the guide plate 7 can be adjusted according to the flow of the raw material, thereby reducing the resistance of the raw material during the process of falling into the discharge channel 6 and reducing the energy consumption of the equipment.

[0027] The usage and advantages of this utility model: This ball mill, which facilitates feeding, operates as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the operator first pours the raw material into the feed hopper 1 through the top opening and simultaneously starts the two vibration motors 101 on the bottom outer wall. This causes the vibration motors 101 to generate a vibration frequency, which in turn causes the entire feed hopper 1, which is screwed to it, to start vibrating. At the same time, the raw material inside the feed hopper 1 is quickly shaken off by the large vibration and falls into the bottom channel of the feed hopper 1, and then enters the feed channel 2 directly below it. Then, the operator can simultaneously start the servo motor 301, causing the output end of the servo motor 301 to start rotating, which in turn causes the screw conveyor 302, which is inserted with it, to rotate. This allows the raw material entering the feed channel 2 to be pushed laterally by the rotating screw conveyor 302 to the end of the feed channel 2. At this time, the cutting ring sleeved on one end of the screw conveyor 302 will rotate and cut the raw material, making it into small pieces. Then, the raw material will continue to be conveyed into the grinding cylinder 5. During this period, the agitator welded to the end of the screw conveyor 302 will continue to move. The mixing shaft 401 and several mixing rods 402 sleeved on the outer wall of the mixing shaft 401 can be driven to rotate together, so that the mixing rods 402 can rotate and stir the raw materials and grinding balls 8 inside the grinding cylinder 5, thereby achieving the grinding operation of the raw materials. After the grinding operation of the raw materials is completed, the operator can open the solenoid valve, so that the ground raw materials in the grinding cylinder 5 can flow into the discharge channel 6. At this time, the raw materials can pass through the screen 601 and fall down into the guide plate 7 along the discharge channel 6. At the same time, the operator can simultaneously start the electric telescopic rods 702 on the left and right sides through the external controller, so that the drive end drives one side of the two plates 703 screwed to them to lift and lower. At the same time, the rotating rod 701 on the other side of the plate 703 will rotate with the lifting and lowering of one side of the plate 703, thereby realizing the rotation and opening of the left and right plates 703, so that the raw materials can slide down the plate 703 to the discharge channel 6 outlet directly below and be discharged outward.
