Description

Technical Field

[0001] This invention relates to the field of plow-type feeders, and more particularly to a plow-type feeder and control method for pelletizing. Background Technology

[0002] The plow-type distributor is a type of unloading machinery that has the advantages of absolute self-locking, no internal or external leakage, extremely high overload capacity, and stable operation.

[0003] In existing methods, most distributors are fixed center-split or single-sided types. They utilize a drive unit to control the raising and lowering of the plow head, simultaneously driving the idler roller assembly via connecting rods. This structure is relatively complex, resulting in incomplete material scraping, especially of sticky materials. This causes material to scatter throughout the conveyor belt during the return journey, increasing the difficulty of cleanup. Furthermore, the use of parallel idler roller assemblies creates gaps between them, making it impossible to maintain a level conveyor belt under the weight of the material. When the plow-type distributor acts on the conveyor belt, the scraper cannot effectively separate the material onto the belt and into the storage trough, leading to significant material spillage on-site. Summary of the Invention

[0004] The purpose of this invention is to provide a plow-type feeder and control method for pelletizing, which simplifies the feeding process and increases efficiency.

[0005] To achieve the above objectives, the present invention provides a plow-type feeder for pelletizing, comprising a fixed bracket and a conveyor belt. A scraping device and a flexible wear-resistant plate are respectively provided above and below the conveyor belt. A pressure plate is connected to the lower part of the scraping device. The scraping device and the fixed bracket are rotatably coupled, and a telescopic push rod is rotatably connected between them. A first linkage mechanism is connected between the flexible wear-resistant plate and the scraping device, and a second linkage mechanism is connected between the flexible wear-resistant plate and the platform.

[0006] As a further improvement of the present invention, the first linkage mechanism includes a first link and a second link that are hinged to each other at one end, the other end of the first link is rotatably connected to the fixed bracket through a first rotating shaft, and the rear end of the scraping device is connected to the first link; the other end of the second link is rotatably connected to the flexible wear-resistant plate.

[0007] As a further improvement of the present invention, the second linkage mechanism includes a third link and a fourth link that are hinged to each other at one end, the other end of the third link is fixedly connected to the platform, and the other end of the fourth link is rotatably connected to the flexible wear-resistant plate.

[0008] As a further improvement of the present invention, the pressure plate is a wear-resistant rubber block.

[0009] As a further improvement of the present invention, the top view projection of the scraping device is triangular, and its width is greater than that of the conveyor belt.

[0010] As a further improvement of the present invention, the flexible wear-resistant plate comprises high molecular weight polyethylene and natural rubber.

[0011] To achieve the above objectives, the present invention also provides a control method for a plow-type feeder for pelleting. When receiving an instruction from the on-site storage tank that material needs to be prepared, the main controller starts the plow-type feeder for pelleting via remote control, allowing the conveyor belt to transport the material. The telescopic push rod drives the scraping device to swing downward, while the first linkage mechanism causes the flexible wear-resistant plate to rise in advance and support the conveyor belt, making the conveyor belt horizontal. Then, the pressure plate located below the scraping device is attached to the conveyor belt. The material, following the direction of movement of the conveyor belt, contacts the pressure plate and is evenly distributed along both sides of the scraping device into the corresponding storage tank.

[0012] Beneficial effects

[0013] Compared with the prior art, the advantages of the plow-type feeder and control method for pelletizing of the present invention are as follows:

[0014] 1. This device is powered by an electro-hydraulic actuator, but considering the different properties of various materials, the structure and installation method of the compartmentation device are optimized to make the material distribution process simpler and more efficient.

[0015] 2. By optimizing the structure and installation method of the distributor, when materials need to be divided into compartments, the telescopic push rod is activated. Using the linkage mechanism, the flexible wear-resistant plate under the conveyor belt is raised in advance to keep the conveyor belt in a horizontal state, ensuring that the conveyor belt fits the pressure plate, reducing the impact and friction on the conveyor belt, making the material distribution efficiency higher, while reducing on-site material spillage and reducing the labor intensity of the staff.

[0016] 3. The pressure plate is a wear-resistant rubber block. The flexible wear-resistant plate is made of high molecular weight polyethylene and natural rubber to reduce damage to the conveyor belt.

[0024] Example

[0025] Specific embodiments of the present invention are as follows: Figures 1 to 4 As shown, a plow-type feeder for pelletizing includes a fixed bracket 4 and a conveyor belt 7. A scraping device 2 and a flexible wear-resistant plate 6 are respectively located above and below the conveyor belt 7. A pressure plate 3 is connected to the lower part of the scraping device 2. The scraping device 2 and the fixed bracket 4 are rotatably connected, and a telescopic push rod 1 is also rotatably connected between them. A first linkage mechanism 5 connects the flexible wear-resistant plate 6 to the scraping device 2, and a second linkage mechanism 9 connects the flexible wear-resistant plate 6 to the platform 101. In this embodiment, the telescopic push rod 1 is an electro-hydraulic push rod.

[0026] The first linkage mechanism 5 includes a first link 51 and a second link 52, which are hinged to each other at one end. The other end of the first link 51 is rotatably connected to the fixed bracket 4 via a first rotating shaft 41. The rear end of the scraping device 2 is connected to the first link 51. The other end of the second link 52 is rotatably connected to the flexible wear-resistant plate 6.

[0027] The second linkage mechanism 9 includes a third link 91 and a fourth link 92 that are hinged to each other at one end. The other end of the third link 91 is fixedly connected to the platform 101, and the other end of the fourth link 92 is rotatably connected to the flexible wear-resistant plate 6.

[0028] The flexible wear-resistant plate 6 comprises high-molecular-weight polyethylene and natural rubber. The pressure plate 3 is a wear-resistant rubber block. The top view projection of the scraper device 2 is triangular, and its width is greater than that of the conveyor belt 7. In use, storage troughs 10 are set on both the left and right sides of the conveyor belt 7. When the material 8 moves with the conveyor belt 7 and passes through the pressure plate 3 and the scraper device 2, the material 8 is separated to the left and right by the triangular scraper device 2 and falls into the corresponding storage trough 10. When there are multiple plow-type distributors for pelletizing, each plow-type distributor for pelletizing is arranged sequentially along the conveying direction of the conveyor belt 7, and the number of storage troughs 10 is twice that of the plow-type distributors for pelletizing.

[0029] The control method of the above-mentioned plow-type feeder for pelleting is as follows: Upon receiving an instruction from the on-site storage trough 10 that material needs to be prepared, the main control unit remotely starts the plow-type feeder for pelleting, allowing the conveyor belt 7 to transport the material 8. The telescopic push rod 1 drives the scraper device 2 to swing downwards, while the first linkage mechanism 5 causes the flexible wear-resistant plate 6 to rise in advance and support the conveyor belt 7, making the conveyor belt 7 horizontal. Then, the pressure plate 3 located below the scraper device 2 is attached to the conveyor belt 7. Here, the flexible wear-resistant plate 6 contacts the conveyor belt 7 earlier than the pressure plate 3, ensuring that the conveyor belt 7 is flat. The material 8 moves with the direction of movement of the conveyor belt 7 and contacts the pressure plate 3. The material 8 is evenly distributed along both sides of the scraper device 2 into the corresponding storage trough 10.

[0030] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
