Description
Technical Field
[0001] This utility model relates to the field of batching equipment technology, and in particular to a feeder using an irregularly shaped hopper. Background Technology
[0002] Conventional feeders employ a vertical shaft structure, such as the circulating heating type automatic heavy-duty feeder disclosed in CN111688073A. In this type of feeder, because the mixing blades rotate horizontally, the material, once it falls due to gravity, will not rise again, resulting in poor mixing uniformity. Based on this structural characteristic, some designers have created feeders with horizontal mixing shafts, such as the backpack-type weightless composite transmission feeder disclosed in CN114345231A, which uses a horizontal mixing shaft design. However, this mixing structure also has drawbacks. Because the bottom of the mixing drum is connected to the extrusion structure, and the connection area is relatively small, the blades on the horizontal mixing shaft in this patent are also small, leading to insufficient mixing. Summary of the Invention
[0003] The technical problem to be solved by this utility model embodiment is to provide a feeder with an irregularly shaped hopper, which solves the problem of material sticking to the inner wall of the mixing drum in the prior art.
[0004] To solve the above-mentioned technical problems, this utility model provides a feeder using an irregularly shaped hopper, comprising: a receiving cylinder, a stirring cylinder, a guide pipe, and a stirring mechanism. The receiving cylinder, stirring cylinder, and guide pipe are arranged from top to bottom and connected. The receiving cylinder is vertically arranged, and the stirring cylinder is horizontally arranged. The diameter of the receiving cylinder is smaller than the maximum diameter of the stirring cylinder, and the axial length of the stirring cylinder is greater than the diameter of the receiving cylinder, so that both ends of the stirring cylinder protrude relative to the outer wall of the receiving cylinder. The stirring mechanism is horizontally installed in the stirring cylinder and includes stirring blades and a stirring shaft. The stirring blades are installed in the stirring cylinder through the stirring shaft. The stirring blades rotate through the chambers of the receiving cylinder, the stirring cylinder, and the guide pipe. The stirring cylinder includes a columnar part and two conical parts, with the two conical parts located on both sides of the columnar part. The stirring blades are in contact with the inner walls of the columnar part and the two conical parts.
[0005] The columnar portion and the two conical portions are arranged laterally along the same central axis. The bottom of the conical portion is an inclined surface, which guides the material to slide towards the columnar portion.
[0006] The stirring blade is S-shaped and includes a stirring rod, a primary stirring blade, and a secondary stirring blade. The stirring rod is connected to the two ends of the primary stirring blade extending in opposite directions. The end of the primary stirring blade is connected to the secondary stirring blade bent inward. The primary stirring blade is attached to the inner wall of the columnar part, and the secondary stirring blade is attached to the inner wall of the conical part.
[0007] The feed tube is horizontally arranged, and a pair of parallel twin screws are installed in the feed tube. The primary stirring plate rotates and passes above the twin screws. The central axis of the primary stirring plate is located in the middle position above the central axes of the two screws of the twin screws.
[0008] The stirring shaft is horizontally positioned, the stirring rod is vertically positioned to the stirring shaft, the two primary stirring blades are parallel to the stirring shaft, and the two secondary stirring blades are parallel to each other.
[0009] The feed pipe includes a receiving hopper, which is installed above the feed pipe and connects the mixing drum to the feed pipe.
[0010] One of the conical portions has a stirring shaft mounting plate on its side, and the stirring shaft is mounted on the stirring shaft mounting plate to rotate. The other conical portion has a glass viewing window on its side.
[0011] The stirring shaft of the stirring mechanism is connected to the power mechanism via a transmission.
[0012] The receiving cylinder is cylindrical, and a flange is provided at the upper end of the receiving cylinder to connect it to the temporary storage tank.
[0013] This utility model provides a feeder using an irregularly shaped hopper. The mixing blades rotate and stir against the inner wall of the mixing drum. The primary mixing blades scrape the material off the inner wall of the cylindrical part of the mixing drum, and the secondary mixing blades scrape the material off the inner wall of the conical part. The material smoothly slides down the inclined surfaces of the cylindrical and conical parts through the receiving hopper into the guide pipe, eliminating material adhesion to the walls. The mixing blades achieve thorough mixing without dead zones. During the mixing and rotation process, the blades pass through the receiving drum, mixing drum, and guide pipe chambers, fully mixing the material in these components. The mixing range is large, ensuring thorough mixing of the material. It is manufactured using sheet metal welding technology, making it easy to manufacture and reducing production costs. The mixing drum has a large capacity and is easy to clean and maintain. Attached Figure Description

[0024] This utility model provides a feeder using an irregularly shaped hopper, such as... Figure 1-5The system includes: a receiving cylinder 1, a mixing cylinder 2, a guide pipe 3, and a mixing mechanism 4. The receiving cylinder 1, the mixing cylinder 2, and the guide pipe 3 are arranged from top to bottom and connected. The receiving cylinder 1 is vertically arranged, and the mixing cylinder 2 is horizontally arranged. The diameter of the receiving cylinder 1 is smaller than the maximum diameter of the mixing cylinder 2, and the axial length of the mixing cylinder 2 is greater than the diameter of the receiving cylinder 1, so that the two ends of the mixing cylinder 2 protrude relative to the outer wall of the receiving cylinder 1. The mixing mechanism 4 is horizontally installed in the mixing cylinder 2. The mixing mechanism 4 includes a mixing blade 41 and a mixing shaft 42. The mixing shaft 42 is installed on the mixing cylinder 2, and the mixing blade 41 is installed in the mixing cylinder 2 through the mixing shaft 42. The mixing blade 41 rotates through the chambers of the receiving cylinder 1, the mixing cylinder 2, and the guide pipe 3, and the mixing blade 41 mixes the materials in the chambers of the receiving cylinder 1, the mixing cylinder 2, and the guide pipe 3.
[0025] The mixing drum 2 includes a cylindrical part 21 and two conical parts 22. The two conical parts 22 are located on both sides of the cylindrical part 21 and are welded and sealed to the cylindrical part 21. The two conical parts 22 and the cylindrical part 21 are welded and sealed to the receiving drum 1. The cylindrical part 21 and the two conical parts 22 are arranged laterally with the same central axis. The bottom of the conical part 22 is an inclined surface. The inclined surface of the conical part 22 guides the material to slide towards the cylindrical part 21 and fall into the guide pipe 3 below.
[0026] like Figure 2 , 4 The stirring blade 41 is attached to the inner wall of the columnar part 21 and the two conical parts 22. The stirring blade 41 is S-shaped and includes a stirring rod 411, a primary stirring blade 412 and a secondary stirring blade 413. The two ends of the stirring rod 411 are connected to the primary stirring blade 412 extending in opposite directions. The end of the primary stirring blade 412 is connected to the secondary stirring blade 413 bent inward. The primary stirring blade 412 is attached to the inner wall of the columnar part 21 and the secondary stirring blade 413 is attached to the inner wall of the conical part 22.
[0027] The stirring shaft 42 is set horizontally, the stirring rod 411 is set vertically to the stirring shaft 42, the two primary stirring blades 412 are parallel to the stirring shaft 42, and the two secondary stirring blades 413 are parallel to each other.
[0028] like Figure 1-5 The feed pipe 3 is set horizontally, such as Figure 4-5 A pair of parallel twin screws 31 are installed in the feed pipe 3. The primary agitator 412 rotates above the twin screws 31, and the central axis of rotation of the primary agitator 412 is located in the middle position above the central axes of the two screws of the twin screws 31. The twin screws 31 convey the material in the feed pipe 3.
[0029] The feed pipe 3 includes a receiving hopper 32, which is welded to the top of the feed pipe 3 and connects the mixing drum 2 to the feed pipe 3.
[0030] like Figure 1-3 A stirring shaft mounting plate 221 is provided on the side of one conical part 22, and the stirring shaft 42 is mounted on the stirring shaft mounting plate 221 for operation and rotation. A glass window 222 is provided on the side of the other conical part 22, through which the material inside the stirring drum 2 can be observed. The glass window 222 can be removed to clean and maintain the inside of the stirring drum 2.
[0031] The stirring shaft 42 of the stirring mechanism 4 is connected to the power mechanism via transmission.
[0032] The receiving cylinder 1 is cylindrical, and a flange 11 is provided at the upper end of the receiving cylinder 1 to connect with the temporary storage tank.
[0033] During operation, the power mechanism provides power to the stirring mechanism 4. The stirring shaft 42 drives the stirring blades 41 to rotate. The primary stirring blades 412 and the secondary stirring blades 413 rotate against the inner wall of the stirring drum 2, preventing the material from adhering to the inner wall of the stirring drum 2. The bottom of the conical part 22 is an inclined surface, which, together with the stirring blades 41, allows the material to smoothly pass through the receiving hopper 32 and enter the guide pipe 3. The material does not adhere to the inner wall of the stirring drum 2, and there are no dead corners for material accumulation in the stirring drum 2. The bottoms of the columnar part 21 and the conical part 22 are connected to the receiving hopper 32, allowing the material in the columnar part 21 and the conical part 22 to easily enter the guide pipe 3. When the stirring blades 41 rotate, they pass through the receiving drum 1, the stirring drum 2, and the receiving hopper 32, making the material in the receiving drum 1, the stirring drum 2, and the receiving hopper 32 more thoroughly mixed. The material in the receiving hopper 32 enters the guide pipe 3, and the screw device in the guide pipe 3 transports the material out of the guide pipe 3.
[0034] In summary, this utility model features a feeder with an irregularly shaped hopper. The mixing blades rotate and stir against the inner wall of the mixing drum. The primary mixing blades scrape the material off the inner wall of the cylindrical part of the mixing drum, and the secondary mixing blades scrape the material off the inner wall of the conical part. The material smoothly slides down the inclined surfaces of the cylindrical and conical parts through the receiving hopper into the guide pipe, eliminating the phenomenon of material sticking to the wall. The mixing blades achieve thorough mixing without dead zones. During the mixing and rotation process, the mixing blades pass through the receiving drum, mixing drum, and guide pipe chambers, fully mixing the material in these chambers. The mixing range is large, and the material is thoroughly mixed. It is manufactured using sheet metal welding technology, which is convenient to manufacture and has low production costs. The mixing drum has a large capacity and is easy to clean and maintain.
