Description

Technical Field

[0001] This utility model relates to the field of compound fertilizer production technology, specifically a raw material mixing device. Background Technology

[0002] In the production process of compound fertilizer, compound fertilizer is characterized by containing a variety of nutrients, which come from different raw materials. They need to be fully mixed to ensure that the various nutrients are evenly dispersed in the fertilizer. Therefore, a raw material mixing device is required.

[0003] A Chinese patent with authorization announcement number CN218573384U discloses a raw material mixing device for bio-organic fertilizer production, including a raw material mixing tank. A motor is fixedly mounted on the top of the raw material mixing tank, and a rotating rod is fixedly mounted on the output shaft of the motor. A bearing is fixedly mounted on the end of the rotating rod away from the motor. A stirring rod is fixedly mounted on the outer edge of the rotating rod, and a rotating block is fixedly mounted on the end of the stirring rod away from the rotating rod. An air hole is opened on the top of the raw material mixing tank. By starting the motor, the rotating rod is driven to rotate, thereby stirring the raw materials and making the raw materials more evenly mixed. The rotating block is driven by the stirring rod to rotate, thereby cleaning the inner wall of the raw material mixing tank, ensuring that the inner wall of the raw material mixing tank is clean and making the rotation efficiency higher.

[0004] However, the above-mentioned device still has some problems. In practical applications, due to the inability to control the feeding speed of different raw materials, some raw materials enter the mixing tank in large quantities while others enter in small quantities. Excessive feeding will lead to uneven mixing of raw materials, affecting the production quality of compound fertilizer. Therefore, a raw material mixing device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a raw material mixing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The raw material mixing device of this utility model includes a fixed frame, a feeding pipe installed inside one side of the fixed frame, a feeding hopper connected to the top side of the feeding pipe, a groove opened inside the bottom end of the feeding hopper, a sliding plate slidably installed inside the groove, a feeding port opened at the center of the sliding plate, a support plate installed outside the feeding pipe, a servo motor installed on the top side of the support plate, a rotating shaft installed at the output end of the servo motor, a cam installed at the working end of the rotating shaft, a connecting plate installed on the protruding part of the cam through a pin, and the connecting plate installed on the bottom side of the sliding plate through a pin, realizing the movement of the sliding plate in the groove, thereby controlling the feeding speed of the raw materials and helping to achieve uniform distribution of the raw materials during the mixing process.

[0007] Preferably, a sieve plate is installed on the inner wall of the middle section of the feed hopper, a bracket is installed on the top side of one end of the fixed frame, a drive motor is installed on one end of the bracket, a rotating shaft is installed on the output end of the drive motor, a mounting frame is installed on the bottom end of the rotating shaft, and a crushing roller is installed between the two sides of the mounting frame through a pin engagement. The crushing roller is set to contact the sieve plate to ensure that the raw materials entering the mixing tank are all in a loose state, thereby improving the mixing uniformity.

[0008] Preferably, a rotating cylinder is rotatably mounted inside the fixed frame on the outside of the feed pipe. A mixing tank is fixedly connected to one side of the rotating cylinder. One end of the feed pipe is in contact with but not connected to the inside of one side of the mixing tank. A stirring motor is mounted on one side of the other end of the fixed frame. A circular gear is mounted on one end of the output end of the stirring motor. A gear ring is mounted on the outside of one end of the mixing tank. The gear ring and the circular gear mesh with each other to realize the rotation of the rotating cylinder.

[0009] Preferably, a connecting shaft is rotatably mounted on one side of the mixing tank. Four sets of three stirring blades are equidistantly mounted on the outer side of the connecting shaft. A turntable is mounted on the outer side of one end of the connecting shaft, and a drive gear is mounted on the other end. A support shaft is rotatably mounted inside the turntable. Three sets of three stirring blades are equidistantly mounted on the outer side of the support shaft. The stirring blades are staggered. A driven gear is mounted on one end of the support shaft. The drive gear and the driven gear mesh with each other. A drive wheel and a driven wheel are respectively mounted on one end of the connecting shaft and the middle of the output end of the stirring motor.

[0010] Preferably, the bottom of the mixing tank is connected to a discharge pipe, and a valve is installed inside the discharge pipe to facilitate the control of the discharge of the mixed raw materials.

[0011] Preferably, a control panel is installed on one side of the mounting bracket. The control panel is used to operate and control the electrical components inside the device, allowing for convenient centralized control of the electrical components inside the device.

[0012] The advantages of this utility model are:

[0013] 1. The rotating shaft at the output end of the servo motor of this utility model drives the cam to rotate. The convex part of the cam will push or pull the connecting plate through the pin shaft as it rotates, so that the slide plate reciprocates in the slide groove. By the reciprocating sliding of the slide plate, the communication area between the feed port and the feed pipe is changed, thereby realizing the control of the raw material feeding speed and helping the raw material to be evenly distributed in the subsequent mixing process.

[0014] 2. The present invention starts the stirring motor, and the circular gear at its output end drives the gear ring to rotate, thereby realizing the rotation of the mixing barrel. This allows the raw materials in the barrel to be continuously tumbled under the action of centrifugal force, etc. At the same time, the driving wheel drives the driven wheel to rotate through the belt, which in turn causes the connecting shaft to rotate. This causes the stirring blades to stir the raw materials in the mixing barrel as they rotate. When the connecting shaft rotates, the support shaft also rotates, causing the stirring blades to rotate. This allows for more comprehensive stirring of the raw materials, improving the mixing efficiency and uniformity of the raw materials. Attached Figure Description

[0022] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-3 As shown, a raw material mixing device includes a fixed frame 1. A feed pipe 2 is installed inside one side of the fixed frame 1. A feed hopper 3 is connected to the top side of the feed pipe 2. A groove 4 is opened inside the bottom end of the feed hopper 3. A slide plate 5 is slidably installed inside the groove 4. A feed inlet 6 is opened at the center of the slide plate 5. A support plate 7 is installed on the outside of the feed pipe 2. A servo motor 8 is installed on the top side of the support plate 7. A rotating shaft 9 is installed at the output end of the servo motor 8. A cam 10 is installed at the working end of the rotating shaft 9. A connecting plate 11 is installed on the protruding part of the cam 10 through a pin. The connecting plate 11 is installed on the bottom side of the slide plate 5 through a pin.

[0024] A screen plate 12 is installed on the inner wall of the middle section of the feed hopper 3. A bracket 13 is installed on the top side of one end of the fixed frame 1. A drive motor 14 is installed on one end of the bracket 13. A rotating shaft 15 is installed on the output end of the drive motor 14. A mounting frame 16 is installed on the bottom end of the rotating shaft 15. A crushing roller 17 is installed between the two sides of the mounting frame 16 through a pin engagement. The crushing roller 17 is in contact with the screen plate 12. A control panel 35 is installed on one side of the fixed frame 1. During operation, in practical applications, different raw materials may have different feeding speeds due to the inability to control the feeding speed. This can result in some raw materials entering the mixing tank 19 in large quantities while others enter in small quantities. Excessive feeding can lead to uneven mixing of raw materials, affecting the production quality of compound fertilizer. Therefore, the servo motor is activated. The motor 8, with its output shaft 9 driving the cam 10 to rotate, has a protruding part that pushes or pulls the connecting plate 11 via a pin as it rotates. This causes the slide plate 5 to slide back and forth in the groove 4 inside the bottom of the feed hopper 3. The back and forth sliding of the slide plate 5 changes the connection area between the feed inlet 6 and the feed pipe 2, thereby controlling the raw material feeding speed and helping to achieve uniform distribution of the raw material in the subsequent mixing process. Specifically, when the protruding part of the cam 10 pushes the connecting plate 11, the connection area between the feed inlet 6 and the feed pipe 2 on the slide plate 5 decreases, and the raw material feeding speed slows down. When the protruding part of the cam 10 pulls the connecting plate 11, the slide plate 5 slides inside the groove 4, the connection area between the feed inlet 6 and the feed pipe 2 increases, and the raw material feeding speed increases.

[0025] When the raw material enters from the feed hopper 3, it first passes through the screen plate 12. The drive motor 14 is started, which drives the rotating shaft 15 to rotate, thereby causing the mounting frame 16 and the crushing roller 17 to rotate. The crushing roller 17 contacts the screen plate 12 and crushes the raw material during the rotation process, ensuring that the raw material entering the mixing tank 19 is in a loose state, avoiding the impact of lumpy raw material on the uniformity of mixing, and improving the overall mixing effect.

[0026] Please see Figure 1 , 2 As shown in Figures 4 and 5, a rotating cylinder 18 is rotatably mounted inside the fixed frame 1 on the outside of the feed pipe 2. A mixing tank 19 is fixedly connected to one side of the rotating cylinder 18. One end of the feed pipe 2 is in contact with the inside of one side of the mixing tank 19 but not connected. A stirring motor 20 is mounted on one side of the other end of the fixed frame 1. A circular gear 21 is mounted on one end of the output end of the stirring motor 20. A gear ring 22 is mounted on the outside of one end of the mixing tank 19. The gear ring 22 and the circular gear 21 mesh with each other.

[0027] A connecting shaft 23 is rotatably mounted on one side of the mixing tank 19. Four sets of three stirring blades 24 are equidistantly mounted on the outer side of the connecting shaft 23. A turntable 26 is mounted on the outer side of one end of the connecting shaft 23. A drive gear 25 is mounted on one end of the connecting shaft 23. A support shaft 27 is rotatably mounted inside the turntable 26. Three sets of three stirring blades 28 are equidistantly mounted on the outer side of the support shaft 27. The stirring blades 24 and the stirring blades 28 are staggered. A driven gear 29 is mounted on one end of the support shaft 27. The drive gear 25 and the driven gear 29 mesh with each other. A drive wheel 30 and a driven wheel 31 are respectively mounted on one end of the connecting shaft 23 and the middle of the output end of the stirring motor 20. The drive wheel 30 and the driven wheel 31 are connected by a belt 32.

[0028] The bottom of the mixing tank 19 is connected to a discharge pipe 33, and a valve 34 is installed inside the discharge pipe 33. During operation, in the compound fertilizer production process, compound fertilizer is characterized by containing multiple nutrients derived from different raw materials. Thorough mixing is necessary to ensure that the various nutrients are evenly dispersed in the fertilizer. Therefore, a raw material mixing device is required. Starting the stirring motor 20 causes the circular gear 21 at its output end to drive the gear ring 22 to rotate, thereby rotating the mixing tank 19. This allows the raw materials inside the tank to continuously tumble under centrifugal force and other effects. The drive wheel 30 at the middle of the output end of the stirring motor 20 drives the driven wheel 31 to rotate via the belt 32, which in turn causes the connecting shaft 23 to rotate. This causes the four sets of stirring blades 24 to stir the raw materials in the mixing tank 19 as they rotate. Since the drive gear 25 and the driven gear 29 mesh with each other, when the connecting shaft 23 rotates, the support shaft 27 will also rotate, causing the stirring blades 28 on the outside of the support shaft 27 to stir the raw materials. Furthermore, the stirring blades 24 and the stirring blades 28 are staggered, which can more comprehensively stir the raw materials and further improve the mixing efficiency and uniformity of the raw materials.

[0029] Once the raw materials are mixed, the valve 34 inside the discharge pipe 33 is opened, and the mixed raw materials are discharged from the discharge pipe 33 under the action of gravity, which facilitates the collection and subsequent processing of the mixed raw materials.

[0030] Working principle: When the servo motor 8 is started, the rotating shaft 9 at its output end drives the cam 10 to rotate. As the cam 10 rotates, the protruding part pushes or pulls the connecting plate 11 through the pin shaft, causing the slide plate 5 to slide back and forth in the groove 4 inside the bottom of the feed hopper 3. Through the back and forth sliding of the slide plate 5, the communication area between the feed inlet 6 and the feed pipe 2 is changed, thereby realizing the control of the raw material feeding speed. This helps to ensure the uniform distribution of the raw material in the subsequent mixing process. That is, when the protruding part of the cam 10 pushes the connecting plate 11, the communication area between the feed inlet 6 and the feed pipe 2 on the slide plate 5 decreases, and the raw material feeding speed slows down; when the protruding part of the cam 10 pulls the connecting plate 11, the slide plate 5 slides inside the groove 4, the communication area between the feed inlet 6 and the feed pipe 2 increases, and the raw material feeding speed increases.

[0031] When the raw material enters from the feed hopper 3, it first passes through the screen plate 12. The drive motor 14 is started, which drives the rotating shaft 15 to rotate, thereby causing the mounting frame 16 and the crushing roller 17 to rotate. The crushing roller 17 contacts the screen plate 12 and crushes the raw material during the rotation process, ensuring that the raw material entering the mixing tank 19 is in a loose state, avoiding the impact of lumpy raw material on the uniformity of mixing, and improving the overall mixing effect.

[0032] When the stirring motor 20 is started, the circular gear 21 at its output end drives the gear ring 22 to rotate, thereby rotating the mixing tank 19. This allows the raw materials inside the tank to be continuously tumbled under the action of centrifugal force and other forces. At the same time, the driving wheel 30 at the middle of the output end of the stirring motor 20 drives the driven wheel 31 to rotate through the belt 32, which in turn causes the connecting shaft 23 to rotate. This causes the four sets of stirring blades 24 to stir the raw materials in the mixing tank 19 as they rotate. Since the driving gear 25 and the driven gear 29 mesh with each other, when the connecting shaft 23 rotates, the support shaft 27 will also rotate, causing the stirring blades 28 on the outside of the support shaft 27 to stir the raw materials. Furthermore, the stirring blades 24 and the stirring blades 28 are staggered, which can more comprehensively stir the raw materials, further improving the mixing efficiency and uniformity of the raw materials.

[0033] Once the raw materials are mixed, the valve 34 inside the discharge pipe 33 is opened, and the mixed raw materials are discharged from the discharge pipe 33 under the action of gravity, which facilitates the collection and subsequent processing of the mixed raw materials.
