Description

Technical Field

[0001] This utility model relates to the technical field of ball mill feeding mechanisms, and in particular to an automatic feeder. Background Technology

[0002] Ball mills are a key crushing equipment widely used in industrial production. They are mainly used for crushing, grinding and mixing materials. Ball mills use a rotating cylinder to cause the grinding media (such as steel balls or steel segments) inside to collide, rub and impact with the materials, thereby achieving crushing and grinding of the materials. During the use of ball mills, a feeding mechanism is required to transport the materials into the ball mill.

[0003] The existing technology has the following problems:

[0004] Existing ball mill feeding devices directly convey materials into the ball mill, but it is difficult to control the amount of material conveyed into the ball mill, resulting in too much or too little material being conveyed, which may lead to poor grinding effect, low grinding efficiency, or material waste. Utility Model Content

[0005] This invention provides an automatic feeder to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An automatic feeder includes a storage bin, a first conveyor belt, and a second conveyor belt. A discharge mechanism is fixedly connected to the lower side of the storage bin, and a clearing mechanism is rotatably connected to the left and right sides of the inner side of the storage bin near the bottom. The first conveyor belt is located below the discharge mechanism, and the second conveyor belt is located below the first conveyor belt near the left side.

[0008] The feeding mechanism includes a platform, the upper side of which is fixedly connected to the lower side of the storage bin. A feeding platform is fixedly connected to the left side of the platform, and a first motor is fixedly connected to the right side of the platform. An auger is fixedly connected to the output end of the first motor, and the auger is located inside the platform and the feeding platform.

[0009] Preferably, two baffles are rotatably connected to the lower side of the feeding platform near the left and right sides. The front and rear sides of the two baffles are rotatably connected to each other. The upper round rods of the two connecting rods are rotatably connected to two hydraulic push rods distributed in front and behind. The lower side of the hydraulic push rods is fixedly connected to the upper side of the feeding platform near the front and rear sides.

[0010] Preferably, a retaining plate is fixedly connected to the left middle part of the baffle located on the right side near the bottom, and the outer side of the retaining plate is movably sleeved in the groove on the lower side of the left baffle near the right side.

[0011] Preferably, a ceramic plate is embedded in the upper side of both baffles.

[0012] Preferably, the unblocking mechanism includes a second motor, the left side of which is fixedly connected to the right side of the storage bin near the bottom. The output end of the second motor is fixedly connected to a rotating rod, and a plurality of horizontally distributed turntables are fixedly connected to the outside of the rotating rod. A rotating seat is movably sleeved on the outside of each of the turntables near the bottom. An unblocking frame is rotatably connected to the lower side of the rotating seat.

[0013] Preferably, the outer side of the unblocking frame is fixedly connected with several horizontally distributed support frames, and the inner front and rear sides of the storage bin are fixedly connected with two front and rear distributed guide rails near the bottom, and the front and rear sides of the support frames are slidably connected to the outer side of the guide rails.

[0014] Preferably, a number of evenly distributed balls are rotatably connected to the inner sides of several rotating seats and the inner sides of the front and rear ends of the support frame, and the balls are located between the left and right sides of the turntable and the upper and lower sides of the guide rail.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-5 As shown, an automatic feeder includes a storage bin 1, a first conveyor belt 2 and a second conveyor belt 3. A discharge mechanism 4 is fixedly connected to the lower side of the storage bin 1. A drainage mechanism 5 is rotatably connected to the left and right sides of the inner side of the storage bin 1 near the bottom. The first conveyor belt 2 is located below the discharge mechanism 4, and the second conveyor belt 3 is located below the first conveyor belt 2 near the left side.

[0026] The feeding mechanism 4 includes a mechanism platform 41, the upper side of which is fixedly connected to the lower side of the storage bin 1. A feeding platform 42 is fixedly connected to the left side of the mechanism platform 41, and a first motor 43 is fixedly connected to the right side of the mechanism platform 41. An auger 44 is fixedly connected to the output end of the first motor 43, and the auger 44 is located inside the mechanism platform 41 and the feeding platform 42.

[0027] It should be noted that the first conveyor belt 2 is a horizontal conveyor belt, and the second conveyor belt 3 is an inclined conveyor belt. Several evenly distributed partitions are provided on the outer sides of both the first conveyor belt 2 and the second conveyor belt 3. The partitions divide the outer sides of the first conveyor belt 2 and the second conveyor belt 3 into multiple areas. The first motor 43 drives the auger 44 to rotate, so that the material inside the storage bin 1 is transported to the first conveyor belt 2 by the auger 44. The first conveyor belt 2 is equipped with a weighing component. When the material under the discharge platform 42 reaches a certain level, the conveying stops. The second conveyor belt 3 drives these materials to move to the left, so that the next partition is aligned with the lower side of the discharge platform 42. The first conveyor belt 2 transfers the material to the second conveyor belt 3. The second conveyor belt 3 can transfer the material into the ball mill, or it can be connected to other conveyor belts for longer-distance transmission.

[0028] like Figure 3 As shown, two baffles 45 are rotatably connected to the lower side of the feeding platform 42 near the left and right sides. Connecting rods 46 are rotatably connected to the front and rear sides of the two baffles 45 near each other. Two hydraulic push rods 47 are rotatably connected to the upper round rods of the two connecting rods 46. The lower side of the hydraulic push rods 47 is fixedly connected to the upper side of the feeding platform 42 near the front and rear sides.

[0029] It should be noted that the hydraulic push rod 47 drives the connecting rod 46 to move up and down. When the connecting rod 46 moves up and down, it drives the side of the baffle 45 that is close to each other to move up and down, causing the baffle 45 to rotate. This prevents the material conveyed by the auger 44 from falling directly onto the first conveyor belt 2, so that the baffle 45 guides the material and reduces the impact of the material on the first conveyor belt 2.

[0030] like Figure 3 As shown, a retaining plate 48 is fixedly connected to the middle left side of the right-side baffle 45 near the bottom. The outer side of the retaining plate 48 is movably sleeved in the groove on the lower side of the left-side baffle 45 near the right side.

[0031] It should be noted that when the section on the first conveyor belt 2 located below the discharge platform 42 has already carried a certain amount of material, the hydraulic push rod 47 drives the baffle 45 to rotate upward, and the clamping plate 48 seals the gap between the two baffles 45 to prevent the material from falling further.

[0032] like Figure 3 As shown, ceramic plates are embedded in the upper side of both baffles 45.

[0033] It should be noted that the ceramic plate can reduce the friction between the material and the baffle 45, allowing the baffle 45 to be made of a material with higher strength and lower hardness, thereby reducing the production cost of the baffle 45.

[0034] like Figure 4 , Figure 5As shown, the unblocking mechanism 5 includes a second motor 51. The left side of the second motor 51 is fixedly connected to the right side of the storage bin 1 near the bottom. The output end of the second motor 51 is fixedly connected to a rotating rod 52. Several horizontally distributed turntables 53 are fixedly connected to the outside of the rotating rod 52. Rotating seats 54 are movably sleeved on the outside of the several turntables 53 near the bottom. Unblocking frame 55 is rotatably connected to the lower side of the rotating seat 54.

[0035] It should be noted that the second motor 51 drives the rotating rod 52 to rotate, and when the rotating rod 52 rotates, it drives the turntable 53 to rotate. When the turntable 53 rotates, it drives the rotating seat 54 to move left and right, which in turn causes the rotating seat 54 to drive the unblocking frame 55 to move left and right.

[0036] like Figure 4 , Figure 5 As shown, several horizontally distributed support frames 56 are fixedly connected to the outer side of the unblocking frame 55, and two front and rear distributed guide rails 57 are fixedly connected to the inner front and rear sides of the storage bin 1 near the bottom. The front and rear sides of the support frame 56 are slidably connected to the outer side of the guide rail 57.

[0037] It should be noted that the support frame 56 and the guide rail 57 work together to stabilize the position of the dredging frame 55, so that the horizontal position and the front and rear positions of the dredging frame 55 remain unchanged.

[0038] like Figure 5 As shown, several rotating seats 54 and the inner sides of the front and rear ends of the support frame 56 are rotatably connected to several evenly distributed balls 58, and the balls 58 are located between the left and right sides of the turntable 53 and the upper and lower sides of the guide rail 57.

[0039] It should be noted that the ball bearing 58 is used to reduce the friction between the rotating seat 54 and the turntable 53, as well as between the support frame 56 and the guide rail 57, to prevent small objects from entering and causing increased friction, which would affect the service life of the components.

[0040] The working principle of this utility model is as follows: First, the first conveyor belt 2 is a horizontal conveyor belt, and the second conveyor belt 3 is an inclined conveyor belt. Several evenly distributed partitions are provided on the outer sides of both the first conveyor belt 2 and the second conveyor belt 3, dividing the outer sides of the first conveyor belt 2 and the second conveyor belt 3 into multiple areas. The first motor 43 drives the auger 44 to rotate, causing the material inside the storage bin 1 to be conveyed onto the first conveyor belt 2 by the auger 44. A weighing component is provided inside the first conveyor belt 2. When the material under the discharge platform 42 reaches a certain level, the conveying stops. The second conveyor belt 3 then moves this material to the left, causing the material to... The material is placed under the feed platform 42 in the partitioned area. The first conveyor belt 2 transfers the material to the second conveyor belt 3. The second conveyor belt 3 can transfer the material into the ball mill or connect to other conveyor belts for longer-distance transmission. The hydraulic push rod 47 drives the connecting rod 46 to move up and down. When the connecting rod 46 moves up and down, it drives the baffles 45 to move up and down on the side that is close to each other, causing the baffles 45 to rotate. This prevents the material conveyed by the auger 44 from falling directly onto the first conveyor belt 2, so that the baffles 45 guide the material and reduce the impact of the material on the first conveyor belt 2. The first motor 43 drives the auger 44. The rotation ensures that the material in the storage bin 1 falls evenly and stably onto the first conveyor belt 2. Baffles then divide the outer sides of the first conveyor belt 2 and the second conveyor belt 3 into multiple sections, ensuring that the material falling into each section has approximately the same quality. This allows for control over the quality of material conveyed by the second conveyor belt 3, avoiding waste or low grinding efficiency. Finally, the second motor 51 drives the rotating rod 52 to rotate. The rotation of the rotating rod 52 drives the turntable 53 to rotate, which in turn drives the rotating seat 54 to move left and right. This, in turn, causes the rotating seat 54 to move the unblocking frame 55 left and right. The support frame 56 and the guide rail 57 work together... The ball bearings 58 are used to stabilize the position of the drain cleaning frame 55, ensuring that the horizontal and front-to-back positions of the drain cleaning frame 55 remain unchanged. The ball bearings 58 are used to reduce the friction between the rotating seat 54 and the turntable 53, as well as between the support frame 56 and the guide rail 57, to prevent small objects from entering and increasing friction, which would affect the service life of the components. The second motor 51 drives the turntable 53 to rotate and the drain cleaning frame 55 to reciprocate left and right, so that the turntable 53 can unclog the material inside the storage bin 1 through the drain cleaning frame 55, preventing the material from accumulating at the bottom inside the storage bin 1 and making it difficult for the material to fall, thus avoiding affecting the stability of the material conveying.
