Description

Technical Field

[0001] The invention relates to the field of plough type distributors, and in particular to a plough type distributor for pelletizing and a control method thereof. Background Art

[0002] The plough type distributor is a kind of unloading machine, which has the advantages of absolute self-locking, no internal and external leakage, great overload capacity and stable operation.

[0003] In the existing methods, most of the distributors are fixed center-split or single-sided, and use a driving device to control the lifting of the plow head, and at the same time combine with the relevant connecting rod to drive the roller group. The structure is relatively complex, and the material cannot be scraped cleanly, especially the sticky material, which causes the conveyor belt to scatter everywhere during the return process, making it more difficult for personnel to clean up. In addition, due to the use of parallel roller groups, there are gaps between the rollers. Under the condition of material gravity, the state of the conveyor belt cannot be guaranteed to be horizontal. When the plow-type distributor acts on the conveyor belt, the scraper cannot effectively separate the material on the conveyor belt into the storage tank, resulting in a large amount of scattered materials on site. Summary of the invention

[0004] The object of the present invention is to provide a pelletizing plough type distributor and a control method, which makes the distribution process simpler and more efficient.

[0005] To achieve the above-mentioned purpose, the present invention provides a plow-type distributor for pellets, comprising a fixed bracket and a conveyor belt, a scraper device and a flexible wear-resistant plate are respectively provided above and below the conveyor belt, and a pressure plate is connected to the lower part of the scraper device; the scraper device and the fixed bracket are rotationally matched, and a telescopic push rod is also rotationally connected between the two; a first connecting rod mechanism is connected between the flexible wear-resistant plate and the scraper device, and a second connecting rod mechanism is connected between the flexible wear-resistant plate and the platform.

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

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

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

[0009] As a further improvement of the present invention, the scraper device has a triangular shape in top view, and its width is greater than the conveyor belt.

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

[0011] To achieve the above-mentioned purpose, the present invention also provides a control method for a pelletizing plow-type distributor. When receiving an instruction that a storage tank on site needs to be prepared, the main control machine starts the pelletizing plow-type distributor through remote control, allowing the conveyor belt to transport the material; the telescopic push rod drives the scraper device to swing downward, and at the same time, the flexible wear-resistant plate is raised upward in advance through the first connecting rod mechanism to support the conveyor belt, so that the conveyor belt is in a horizontal state, and then the pressure plate located at the bottom of the scraper device is attached to the conveyor belt; the material contacts the pressure plate along the movement direction of the conveyor belt, and is evenly distributed to the corresponding storage tank along both sides of the scraper device.

[0012] Beneficial Effects

[0013] Compared with the prior art, the pelletizing plow type distributor and control method of the present invention have the following advantages:

[0014] 1. This device is powered by an electro-hydraulic push rod, but considering the different properties of each material, the structural installation method of the bin separation device is optimized to make the material separation process simpler and more efficient.

[0015] 2. By optimizing the structure and installation method of the distributor, when the materials need to be divided into bins, start the telescopic push rod and use the connecting rod mechanism to buffer and raise the flexible wear-resistant plate under the conveyor belt in advance, so that the conveyor belt is in a horizontal state, ensuring the fit between the conveyor belt and the pressure plate, reducing the impact and friction on the conveyor belt, making the material distribution more efficient, reducing the bulk material on site, and reducing the labor intensity of the personnel on duty.

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

[0023] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0024] Example

[0025] The specific embodiments of the present invention are as follows Figures 1 to 4 As shown, a pelletizing plow type distributor comprises a fixed bracket 4 and a conveying belt 7. A scraper device 2 and a flexible wear-resistant plate 6 are respectively provided above and below the conveying belt 7. A pressing plate 3 is connected to the lower part of the scraper device 2. The scraper device 2 is rotationally matched with the fixed bracket 4, and a telescopic push rod 1 is also rotationally connected between the two. A first connecting rod mechanism 5 is connected between the flexible wear-resistant plate 6 and the scraper device 2, and a second connecting rod mechanism 9 is connected between the flexible wear-resistant plate 6 and the platform 101. In this embodiment, the telescopic push rod 1 is an electro-hydraulic push rod.

[0026] The first link mechanism 5 includes a first link 51 and a second link 52, one end of which is hinged to each other, the other end of the first link 51 is rotatably connected to the fixed bracket 4 through the first rotating shaft 41, and the rear end of the scraper 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 link mechanism 9 includes a third link 91 and a fourth link 92 which 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 includes high molecular polyethylene and natural rubber. The pressing plate 3 is a wear-resistant rubber block. The top projection of the scraper device 2 is triangular, and its width is greater than the conveyor belt 7. When in use, storage troughs 10 are provided on both sides of the conveyor belt 7. When the material 8 moves with the conveyor belt 7 and passes through the pressing plate 3 and the scraper device 2, the material 8 is separated to the left and right sides by the triangular scraper device 2 and falls into the corresponding storage troughs 10. When there are multiple pelletizing plow-type distributors, each pelletizing plow-type distributor is arranged in sequence along the conveying direction of the conveyor belt 7, and the number of storage troughs 10 is twice that of the pelletizing plow-type distributors.

[0029] The control method of the above-mentioned pelletizing plow-type distributor is as follows: when receiving the instruction that the on-site storage tank 10 needs to prepare materials, the main control machine starts the pelletizing plow-type distributor through remote control, and allows the conveyor belt 7 to convey the conveying material 8. The telescopic push rod 1 drives the scraper device 2 to swing downward, and at the same time, the first connecting rod mechanism 5 allows the flexible wear-resistant plate 6 to rise upward in advance and support the conveyor belt 7, so that the conveyor belt 7 is in a horizontal state, and then the pressure plate 3 located at the bottom of 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 to ensure that the conveyor belt 7 is flat. The material 8 moves in 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 to the corresponding storage tank 10.

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