Description

Technical Field

[0001] This utility model relates to an automatic material feeding and conveying device, and is situated in the technical field of brewing raw material transportation equipment. Background Technology

[0002] The brewing process requires a large amount of grain as raw material. Grain transported from outside is usually unloaded and then conveyed to grain silos via belt conveyors, or vehicles can directly enter the grain silos for unloading. However, during the brewing process, a certain amount of grain needs to be transported to a designated location for pre-processing. Due to the long distance between the grain silos and the production workshop, belt conveyors are costly, and manual transportation is time-consuming and labor-intensive. Often, overhead cranes are used to lift the grain into hoppers. However, even after the hoppers reach the designated location, the grain still needs to be manually opened to unload and then transported again to pre-processing equipment for crushing or washing. This process is cumbersome, cannot achieve automatic material feeding and guiding, and is detrimental to improving production efficiency. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to provide an automatic material feeding and conveying device to solve the problems existing in the prior art. The specific technical solution is as follows:

[0004] An automatic material feeding and conveying device includes: a hopper support frame and a conveying support frame. A grain hopper is fixedly connected to the hopper support frame, and a sealing device is rotatably connected to the material discharge port at the bottom of the grain hopper. A receiving frame corresponding to the material discharge port is fixedly connected to the top of the conveying support frame, and a guiding device is fixedly connected to the bottom of the receiving frame. When the conveying support frame supports the hopper support frame, the sealing device contacts the edge of the receiving frame and generates a force, causing the sealing device to rotate and open the material discharge port.

[0005] Preferably, the grain hopper is a square hopper, and the sealing device includes a first rotating assembly and a second rotating assembly symmetrically arranged on both sides of the grain hopper. The first rotating assembly includes an arc-shaped sealing plate, with movable plates fixedly connected to both ends of the arc-shaped sealing plate. The movable plates are rotatably connected to the grain hopper, and support rods are provided at the bottom corners of the movable plates. A return spring is provided between the support rods on the first rotating assembly and the second rotating assembly. The first rotating assembly and the second rotating assembly have the same structure. When the first rotating assembly and the second rotating assembly are reset, the movable plate and the arc-shaped sealing plate can be directly connected to seal the discharge port.

[0006] Furthermore, the material discharge port includes an arc-shaped convex plate and a side plate. The arc-shaped convex plate corresponds to the arc-shaped sealing plate and is located on the same side as the movable plate. The side plate is connected to both sides of the arc-shaped convex plate. When the first rotating assembly and the second rotating assembly are docked, the side plate is in contact with the arc-shaped sealing plate.

[0007] Furthermore, a material distribution device is fixedly connected to the middle of the arc-shaped convex plate.

[0008] Furthermore, the material distribution device is a triangular angle iron with its opening facing downwards.

[0009] Furthermore, a mounting groove is fixedly connected to the middle of the arc-shaped convex plate, and a sealing gasket is installed in the mounting groove.

[0010] Furthermore, the receiving rack is square and protrudes upward from the conveying support frame, with side platforms on its top four sides for supporting the support rods.

[0011] Preferably, the material guiding device includes a conveying hopper fixedly connected to the receiving frame, a spiral conveying rod rotatably connected inside the conveying hopper, and one end of the spiral conveying rod being connected to a drive motor fixedly installed on the outside of the conveying hopper.

[0012] This invention involves placing the hopper support frame onto the conveyor support frame via a crane. During this process, the support rods of the first and second rotating components on both sides of the hopper support frame contact the edge platform at the top of the receiving frame and slide to both sides, causing the first and second rotating components to rotate outwards, opening the discharge port and allowing the grain in the grain hopper to fall automatically. The grain falls into the guiding device, and the rotation of the screw conveyor rod transports the grain to the designated position, simplifying the feeding process and eliminating the need for manual handling of the grain.

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

[0020] like Figure 1-5 As shown, an automatic material feeding and conveying device includes: a hopper support frame 1 and a conveying support frame 2. A grain hopper 3 is fixedly connected to the hopper support frame 1, and a sealing device is rotatably connected to the material discharge port at the bottom of the grain hopper 3. A receiving frame 4 corresponding to the material discharge port is fixedly connected to the top of the conveying support frame 2, and a guiding device 5 is fixedly connected to the bottom of the receiving frame 4. When the conveying support frame 2 supports the hopper support frame 1, the sealing device contacts the edge of the receiving frame 4 and generates a force, causing the sealing device to rotate and open the material discharge port. By automatically opening the material discharge port at the bottom of the grain hopper 3 through the contact between the sealing device and the receiving frame 4, the grain falls into the guiding device 5, achieving rapid conveying of the grain. The process requires no manual intervention, significantly improving work efficiency.

[0021] The grain hopper 3 is a square hopper. The sealing device includes a first rotating assembly 6 and a second rotating assembly 7 symmetrically arranged on both sides of the grain hopper 3. The first rotating assembly 6 includes an arc-shaped sealing plate 601, with movable plates 602 fixedly connected to both ends of the arc-shaped sealing plate 601. The movable plates 602 are rotatably connected to the grain hopper 3. Support rods 603 are provided at the bottom corners of the movable plates 602. A return spring 604 is provided between the support rods 603 on the first rotating assembly 6 and the second rotating assembly 7. The first rotating assembly 6 and the second rotating assembly 7 have the same structure. When the first rotating assembly 6 and the second rotating assembly 7 are reset, the movable plate 602 and the arc-shaped sealing plate 601 can be directly connected to seal the discharge port. The support rods 603 contact the receiving frame 4, causing the first rotating assembly 6 and the second rotating assembly 7 to rotate and open the discharge port. When all the grain has fallen, the gantry crane lifts the hopper support frame 1, the return spring 604 contracts, and the first rotating assembly 6 and the second rotating assembly 7 are reset, resealing the discharge port. The hopper support frame 1 is equipped with legs that can be placed directly on the ground for easy grain loading. In actual operation, multiple hopper support frames 1 can work alternately to improve work efficiency.

[0022] The discharge port includes an arc-shaped convex plate 8 and a side plate 9. The arc-shaped convex plate 8 corresponds to the arc-shaped sealing plate 601 and is located on the same side as the movable plate 602. The side plate 9 is connected to both sides of the arc-shaped convex plate 8. When the first rotating assembly 6 and the second rotating assembly 7 are docked, both the side plate 9 and the arc-shaped convex plate 8 are in contact with the arc-shaped sealing plate 601 to prevent the grain from entering the outside of the discharge port and falling off during transportation.

[0023] The center of the arc-shaped convex plate 8 is fixedly connected to the material distribution device 10, which is a triangular angle iron with its opening facing downwards. The material distribution device 10 diverts the falling grain, allowing it to slowly fall into the guiding device 5, thus smoothly conveying the grain and reducing the working pressure on the drive motor 503.

[0024] The arc-shaped convex plate 8 is fixedly connected to the mounting groove 11, and a sealing gasket is installed in the mounting groove 11. When the first rotating assembly 6 and the second rotating assembly 7 are closed, the two clamp the sealing gasket by the action of the return spring 604 to prevent grain from leaking out of the gap between them.

[0025] The receiving rack 4 is square and protrudes upward from the conveying support frame 2. Its top has four side platforms 12 for supporting the support rod 603. The guiding device 5 includes a conveying hopper 501 fixedly connected to the receiving rack 4. A spiral conveying rod 502 is rotatably connected inside the conveying hopper 501. One end of the spiral conveying rod 502 is connected to a drive motor 503 fixedly installed on the outside of the conveying hopper 501.

[0026] The working principle of this utility model is as follows: The hopper support frame 1 is moved to the position of the conveying support frame 2 by a crane hoisting it, and then slowly descends so that the receiving frame 4 of the conveying support frame 2 can support the sealing device of the hopper support frame 1. During the descent of the hopper support frame 1, the support rods 603 on the first rotating component 6 and the second rotating component 7 contact the side platform 12 at the top of the receiving frame 4. The hopper support frame 1 continues to descend, and the support rods 603 slide along the side platform 12, driving the first rotating component 6 and the second rotating component 7 to rotate. The sealing device automatically opens, and the discharge port leaks out, allowing the grain to fall automatically. During the falling process, the grain is diverted by the material distribution device 10, causing the grain to slowly slide down from both sides of the conveying hopper 501. The spiral conveying rod 502 rotates and continuously guides the sliding grain to the designated position. After the material is discharged, the hoisting hopper support frame 1 is lifted, and the return spring 604 connected to the support rod 603 contracts, returning the first rotating component 6 and the second rotating component 7 to their initial positions, resealing the discharge port for easy refilling. The grain hopper 3 of this utility model can also be equipped with scale lines. The scale line positions correspond to different grain weights, which makes it convenient to transport grain of a specified weight and avoids repeated loads, thus affecting efficiency.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
