Description

Technical Field

[0001] This utility model belongs to the field of dry mortar production technology, and in particular relates to an automated feeding device for dry mortar production. Background Technology

[0002] The automated feeding device for dry mortar production is an intelligent equipment system used in the dry mortar production process to automatically convey, meter, and feed raw materials (such as cement, fly ash, quartz sand, additives, etc.).

[0003] Traditional automated feeding devices for dry mortar production typically use screw conveyors to transport and feed the dry powder. However, when the dry powder being transported is relatively moist, blockages can easily occur at the discharge port of the screw conveyor, requiring the conveyor to be stopped for cleaning. In severe cases, the screw conveyor may even jam, and the motor may be damaged due to overload, overheating, or current surges, resulting in economic losses and requiring a significant amount of time for repairs. Utility Model Content

[0004] The purpose of this invention is to provide an automated feeding device for dry mortar production. By setting up a vibration mechanism, specifically a motor driving a turntable to rotate, the push shaft pushes the arc-shaped flipping plate. At this time, the spring is compressed. After the push shaft disengages from the arc-shaped flipping plate, the arc-shaped flipping plate will return to its original position due to the elasticity of the spring. At this time, the collision block collides with the discharge pipe. This process repeats, causing the discharge pipe to vibrate continuously, which can prevent blockage in the discharge pipe, ensure stable feeding of raw materials, and improve the service life of the screw conveyor. It solves the problem that traditional screw conveyors are prone to blockage at the discharge port when conveying relatively moist dry powder.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an automated feeding device for dry mortar production, comprising a base frame, a screw conveyor mounted on the base frame via a bracket, a feed hopper fixedly connected to the top left side of the screw conveyor, a discharge pipe fixedly connected to the bottom right side of the screw conveyor, and a weighing sensor installed at the bottom of the screw conveyor. It also includes: A vibration mechanism is provided, located on the outside of a discharge pipe. The vibration mechanism includes a fixed plate fixedly connected to the surface of the discharge pipe; an arc-shaped tilting plate is positioned above the fixed plate; a limit shaft is fixedly connected to the bottom of the arc-shaped tilting plate; a collision block is fixedly connected to the rear inner side of the arc-shaped tilting plate; a motor is fixedly connected to the bottom of the fixed plate; a turntable is fixedly connected to the output end of the motor via bolts; and a push shaft is fixedly connected to the top of the turntable. An adjustment mechanism is provided on the left side of the feed hopper, and the adjustment mechanism is used to adjust the size of the opening at the bottom of the feed hopper; The arc-shaped flipping plate is arc-shaped, the turntable is located on top of the fixed plate, and there is a gap between the bottom of the arc-shaped flipping plate and the fixed plate.

[0006] Furthermore, the bottom of the feed hopper is connected to the screw conveyor, and the bottom right side of the screw conveyor is connected to the discharge pipe. The bottom of the discharge pipe is used to connect to the mixing equipment. Both the feed hopper and the discharge pipe are connected to the screw conveyor by welding. The feed hopper is used to store raw materials.

[0007] Furthermore, the limiting shaft is rotatably connected to the fixed plate via a bearing, and a spring is fixedly connected to the front position of the inner side of the arc-shaped flipping plate. The side of the spring away from the arc-shaped flipping plate is fixedly connected to the surface of the discharge pipe. The flipping plate is restricted by the limiting shaft, so that the front and rear positions move in opposite directions.

[0008] Furthermore, when the push shaft rotates, its outer surface will contact the outer side of the arc-shaped flipping plate. The side of the collision block facing the discharge pipe is set with an arc surface, and the arc surface on the collision block contacts the outer surface of the discharge pipe. Because the collision block is set with an arc surface, the arc-shaped flipping plate can smoothly drive the collision block to move when it moves, avoiding jamming.

[0009] Furthermore, the adjustment mechanism includes a fixed frame fixedly connected to the left side of the feed hopper, an electric push rod fixedly connected to the left side of the fixed frame, and an adjustment plate fixedly connected to the output end of the electric push rod; The adjusting plate slides through the feed hopper and extends into the feed hopper, and the feed hopper is used to adjust the size of the opening at the bottom of the feed hopper.

[0010] Furthermore, a guide frame is fixedly connected to the inner wall of the feed hopper. The inner side of the guide frame is inclined, and the inclined surface of the guide frame is used to guide the raw material. Supporting ridges are fixedly connected to both the front and back sides of the inner wall of the feed hopper. The top of the supporting ridge contacts the bottom of the adjusting plate, and the top of the adjusting plate contacts the bottom of the guide frame. A large gap is left between the right side of the supporting ridge and the inner wall of the feed hopper. The supporting ridge supports the adjusting plate, making the adjusting plate more stable when it moves. Since there is a large space between the right side of the supporting ridge and the inner wall of the feed hopper, when the adjusting plate moves to the right, it will push out the raw material remaining on the supporting ridge, thereby avoiding the accumulation of raw material on the supporting ridge.

[0011] This utility model has the following beneficial effects: 1. This utility model incorporates a vibration mechanism. Specifically, when the motor starts and drives the turntable to rotate, the push shaft pushes the arc-shaped flipping plate. At this time, the spring is compressed. After the push shaft disengages from the arc-shaped flipping plate, the arc-shaped flipping plate will return to its original position due to the elasticity of the spring. At this time, the collision block collides with the discharge pipe. This process repeats, causing the discharge pipe to vibrate continuously. This prevents blockages in the discharge pipe, ensures stable material feeding, and improves the service life of the screw conveyor.

[0012] 2. This utility model uses an adjustment mechanism, specifically an electric push rod to move an adjustment plate to the left or right for adjustment. When the adjustment plate moves to the left, the opening at the bottom of the feed hopper increases; when the adjustment plate moves to the right, the opening at the bottom of the feed hopper decreases. This controls the material feeding speed in the feed hopper and avoids clogging caused by excessive material feeding at one time by adjusting the feeding speed.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] 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.

[0018] Please see Figures 1-5 As shown, this utility model is an automated feeding device for dry mortar production, including a base frame 1, a screw conveyor 11 mounted on the base frame 1 via a bracket, a feed hopper 12 fixedly connected to the top left side of the screw conveyor 11, a discharge pipe 13 fixedly connected to the bottom right side of the screw conveyor 11, a weighing sensor 14 installed at the bottom of the screw conveyor 11, and also including: Vibration mechanism 2 is located on the outside of discharge pipe 13. Vibration mechanism 2 includes a fixed plate 21 fixedly connected to the surface of discharge pipe 13. An arc-shaped flipping plate 22 is arranged above the fixed plate 21. A limit shaft 23 is fixedly connected to the bottom of the arc-shaped flipping plate 22. A collision block 25 is fixedly connected to the rear inner side of the arc-shaped flipping plate 22. A motor 211 is fixedly connected to the bottom of the fixed plate 21. A turntable 212 is fixedly connected to the output end of the motor 211 by bolts. A push shaft 213 is fixedly connected to the top of the turntable 212. Motor 211 drives turntable 212 to rotate, which in turn pushes the arc-shaped flipping plate 22 with push shaft 213. At this time, spring 24 is compressed. After push shaft 213 disengages from arc-shaped flipping plate 22, arc-shaped flipping plate 22 will return to its original position due to the elasticity of spring 24. At this time, collision block 25 collides with discharge pipe 13. This process repeats, causing continuous vibration in discharge pipe 13, which can prevent blockage in discharge pipe 13, ensure stable feeding of raw materials, and improve the service life of screw conveyor 11. Adjustment mechanism 3 is located on the left side of feed hopper 12 and is used to adjust the size of the opening at the bottom of feed hopper 12; the arc-shaped flip plate 22 is arc-shaped and the turntable 212 is located on the top of the fixed plate 21, with a gap between the bottom of the arc-shaped flip plate 22 and the fixed plate 21.

[0019] The bottom of the feed hopper 12 is connected to the screw conveyor 11, and the bottom right side of the screw conveyor 11 is connected to the discharge pipe 13. The bottom of the discharge pipe 13 is used to connect to the mixing equipment.

[0020] The limiting shaft 23 is rotatably connected to the fixed plate 21 via a bearing. A spring 24 is fixedly connected to the front position of the inner side of the arc-shaped flip plate 22. The side of the spring 24 away from the arc-shaped flip plate 22 is fixedly connected to the surface of the discharge pipe 13.

[0021] When the push shaft 213 rotates, its outer surface will contact the outer side of the arc-shaped flip plate 22. The side of the collision block 25 facing the discharge pipe 13 is set with an arc surface, and the arc surface on the collision block 25 contacts the outer surface of the discharge pipe 13.

[0022] The adjusting mechanism 3 includes a fixed frame 31 fixedly connected to the left side of the feed hopper 12. An electric push rod 32 is fixedly connected to the left side of the fixed frame 31, and an adjusting plate 33 is fixedly connected to the output end of the electric push rod 32. When the electric push rod 32 is activated, it drives the adjusting plate 33 to move to the left or right for adjustment. When the adjusting plate 33 moves to the left, the opening at the bottom of the feed hopper 12 increases. When the adjusting plate 33 moves to the right, the opening at the bottom of the feed hopper 12 decreases, thereby controlling the material feeding speed in the feed hopper 12. By adjusting the feeding speed, the situation of excessive material feeding at one time causing blockage is avoided. The adjusting plate 33 slides through the feed hopper 12 and extends into the interior of the feed hopper 12. The feed hopper 12 is used to adjust the size of the opening at the bottom of the feed hopper 12.

[0023] A guide frame 34 is fixedly connected to the inner wall of the feed hopper 12. The inner side of the guide frame 34 is set with an incline. The incline on the guide frame 34 is used to guide the raw material. Supporting protrusions 35 are fixedly connected to the front and back of the inner wall of the feed hopper 12. The top of the supporting protrusion 35 contacts the bottom of the adjusting plate 33, and the top of the adjusting plate 33 contacts the bottom of the guide frame 34. A large gap is left between the right side of the supporting protrusion 35 and the inner wall of the feed hopper 12.

[0024] One specific application of this embodiment is: In operation, the screw conveyor 11 is first started to rotate the internal screw blades. Raw materials (such as cement, fly ash, quartz sand, additives, etc.) are added to the feed hopper 12. The raw materials are then guided through the guide frame 34 and transported into the screw conveyor 11. The weighing sensor 14 weighs the screw conveyor 11. During material feeding, the position of the adjusting plate 33 is adjusted according to the feeding speed. The electric push rod 32 is activated to move the adjusting plate 33 left or right for adjustment. When the adjusting plate 33 moves to the left, ... The opening at the bottom of the feed hopper 12 is enlarged. When the adjusting plate 33 moves to the right, the opening at the bottom of the feed hopper 12 decreases, thereby controlling the material feeding speed in the feed hopper 12. When the adjusting plate 33 moves, it will move on the support rib 35, which in turn supports the adjusting plate 33, making the adjusting plate 33 more stable when it moves. Furthermore, there is a large space between the right side of the support rib 35 and the inner wall of the feed hopper 12. When the adjusting plate 33 moves to the right, it will push out the raw material remaining on the support rib 35, thereby preventing the accumulation of raw material on the support rib 35. The screw conveyor 11 transports the raw materials to the discharge pipe 13 and discharges them into the mixing equipment, achieving automatic feeding. When feeding the raw materials, the start motor 211 drives the turntable 212 to rotate, and the push shaft 213 will rotate along with it. When the push shaft 213 contacts the arc-shaped flip plate 22, it will push the arc-shaped flip plate 22 forward. At this time, the spring 24 is squeezed. Since the bottom of the arc-shaped flip plate 22 rotates on the fixed plate 21 through the limit shaft 23, the back end of the arc-shaped flip plate 22 will drive the collision block 25 away from the discharge pipe 13. When the push shaft 213 disengages from the arc-shaped flip plate 22, the arc-shaped flip plate 22 will be reset by the elasticity of the spring 24. At this time, the collision block 25 will be reset and collide with the discharge pipe 13, thereby causing the discharge pipe 13 to vibrate. This process is repeated to make the discharge pipe 13 vibrate continuously, which can prevent blockage in the discharge pipe 13 and ensure stable feeding of raw materials.
