[0002] A chain conveyor is a common material conveying equipment, which is widely used in many industries such as food processing, beverage production, electronic manufacturing, packaging, and chemical industry. Its core components are chains and chain plates. The chains are driven by a motor to drive the chain plates to move, realizing the continuous conveying of materials. However, during the working process of a traditional chain conveyor, materials are likely to accumulate on the working surface of the chain plates, making it difficult for the materials to enter the next process evenly and stably. In severe cases, it may even cause blockage of the production line.

[0003] In the prior art, for example, in the utility model patent with the publication number CN201890555U, the rotating drum is distributed with nail heads, so as to realize the dispersion of materials during the rotating work.

Detailed implementation manners

[0047] Please refer to Figures 1-9 , in the embodiment of the present invention, a chain plate conveyor for material transportation includes: a support frame 12, a conveyor main body 1, a material leveling unit 2, side baffles 11 and a collection funnel 13; the support frame 12 is vertically fixed at the lower end of the conveyor main body 1, and two side baffles 11 are symmetrically installed on both sides of the conveyor main body 1; the conveyor main body 1 is divided into a horizontal transmission section and an inclined transmission section before and after, and a collection funnel 13 is arranged at the upper end of its inclined transmission section;

[0048] A dispersing system 14 is rotatably connected in the collection funnel 13; it is used to disperse the materials in the collection funnel 13 so that they are finally evenly dispersed and conveyed;

[0049] The material leveling unit 2 is installed in the middle of the inclined transmission section of the conveyor main body 1 and is used for guiding and preprocessing the materials on the conveyor main body 1.

[0050] In this embodiment, the material leveling unit 2 includes:

[0051] An outer frame 21, which is vertically and slidably installed on the inclined transmission section of the conveyor main body 1; a control cylinder 22 is connected between the outer frame 21 and the conveyor main body 1; so as to be able to effectively adjust the vertical installation height between the outer frame 21 and the conveyor main body 1;

[0052] A material deflecting mechanism 3, which is horizontally installed in the outer frame 21, and the material deflecting mechanism 3 deflects the excess materials on the conveyor main body 1 horizontally to one side;

[0053] A material collector 4, which is fixed in the outer frame 21 and is located behind the working station of the material deflecting mechanism 3. The material collector 4 is close to the guiding end of the material deflecting mechanism 3 and is used for collecting and processing the excess materials conveyed by the material deflecting mechanism 3;

[0054] A spraying unit 5, which is fixed in the outer frame 21 and is horizontally connected to one side of the material collector 4. The spraying unit 5 is communicated with the discharge port of the material collector 4 and is used for spraying the materials onto the conveyor main body. Specifically, when the piled-up materials on the conveyor main body pass through the material deflecting mechanism 3, they can be horizontally guided to the corresponding side of the material collector 4 by the material deflecting mechanism 3. At this time, the materials roll and are distributed to the material collector 4, so that the material collector 4 can collect them completely. The collected materials can be temporarily stored or synchronously sprayed onto the conveyor main body 1 through the spraying unit 5.

[0055] As a preferred embodiment, the horizontal distance between the spraying unit 5 and the material deflecting mechanism 3 is not less than 0.5 m, and a vision scanner is arranged between the spraying unit 5 and the material deflecting mechanism 3. The vision scanner acquires the material accumulation image on the conveyor main body 1 and guides the adaptive adjustment of the spraying unit 5. That is to say, the vision scanner uses a high-resolution camera or other sensors to real-time collect the distribution of the materials on the conveyor main body 1 after being deflected by the material deflecting mechanism 3. The collected image data is transmitted to the control system. Through image recognition and analysis algorithms, the accumulation position, thickness and distribution of the materials are accurately judged, so as to judge the material vacancy position on the conveyor main body 1, and the spraying unit 5 is used to fill the material conveyance, realizing the precise control and uniform distribution of the materials on the conveyor main body 1;

[0056] In this embodiment, the material deflecting mechanism 3 includes:

[0057] A machine shell 31, which is fixed on the outer frame 21. Two guide rollers 32 are arranged in parallel below the machine shell 31, and spiral blades are arranged on both of the two guide rollers 32;

[0060] The transmission gear 36 meshes with the two main gears 35.

[0061] In this embodiment, the spiral vanes on the two material guiding rollers 32 are arranged in the same direction and are staggeredly distributed, that is, the two material guiding rollers 32 are arranged one in front of the other. When the material guiding rollers 32 rotate synchronously, the materials are guided to one side, realizing the uniform distribution of the materials on the conveyor main body 1; the optimal number of material guiding rollers can be set to four or five to further improve the material leveling operation on the accumulated materials on the conveyor main body.

[0066] As a preferred embodiment, spring covers 47 are installed at the ports of the straight channels 46 in the material bin 45. That is to say, when the bucket wheel rotates, the hoppers 44 at the lower part shovel the materials. When the hopper 44 moves to the position directly above, the materials can enter the straight channels 46, and the spring covers 47 open, so as to store in the material bin 45; and at this time, the straight channels 46 at the lower positions in the bucket wheel are in a blocked state through the spring covers 47 to prevent the materials from leaking out.

[0068] The spiral guiding pipe 51 is horizontally connected to one side of the material collector 4, and a discharge channel 52 is provided on the side wall of the spiral guiding pipe 51;

[0074] Vertically fixed at each discharge hole 56 below the material leveling plate 54 is an electric telescopic device 58, and the telescopic end of the electric telescopic device 58 is connected to the blocking valve; thus, the opening and closing degree of each discharge hole 56 can be effectively controlled, facilitating accurate blanking.

[0075] One end of each of the sub-edge plates 57 is rotatably connected to the machine chamber 53. A movable rod 59 is horizontally slidably connected inside the machine chamber 53, and the other end of each of the sub-edge plates 57 is hinged to the movable rod 59; a linear oscillator 510 is installed inside the machine chamber 53, and the output end of the linear oscillator 510 is connected to the movable rod 59. It should be noted that medium-sized hole structures can be provided on both sides of the machine chamber 53, and the movable rod can be flexibly installed inside the machine chamber 53 through the medium-sized holes, so as to control the deflection of each sub-edge plate 57 during horizontal sliding, realizing the material leveling effect during discharging.
