Description

Technical Field

[0001] The invention belongs to the technical field of conveyors, in particular to a safe scraper conveyor. Background Art

[0002] Scraper conveyor is a conveyor that uses a scraper chain to transport bulk materials in a trough. It is widely used in coal mines, chemical mines, metal mines and power plants to transport coal, gangue or other materials.

[0003] The scraper conveyor in the prior art operates in conjunction with the rotating scraper of the chain inside the conveyor during use, and pushes the input bulk material for transportation. However, some bulk material structures are small in size. During transportation, the fallen bulk material is easy to fall into the gap of the chain. The remaining bulk material cannot be separated from the chain in time and is transported to the sprocket for extrusion under the movement of the chain. On the one hand, part of the bulk material is broken into powder, which reduces the quality of bulk material transportation. On the other hand, for bulk materials with a harder texture, the sprocket is damaged during the extrusion process, which greatly reduces the safety and stability of the conveyor. In addition, during the transportation of bulk powder, the powder adheres to the chain, which increases the friction with the sprocket, causing wear and overheating. During the transportation process, the conveyor is affected by the bulk material, and the safety and stability of the conveyor itself are greatly reduced, thereby reducing the actual service life and the conveying effect is poor.

[0004] In addition, the scraper conveyor in the prior art has a good conveying effect during the conveying process due to the large surface area of ​​the scraper. However, after the transportation is completed, an equivalent amount of powder adheres to the outer surface of the scraper, resulting in a large amount of powder remaining inside the conveyor. The conveyor discharge separation effect is poor, and the powder remaining in the conveyor further affects the operating performance of the conveyor and is difficult to clean.

[0039] Embodiment 1: When in use, start the power unit on the outside of the conveyor, and rotate the sprocket to drive the chain to rotate, so that the scraper assemblies 2 fixed on both sides of the chain move synchronously, and put the material from the discharge port on the top of the shell 1, and the material falls downward into the interior of the shell 1, and the scraper assembly 2 located at the bottom pushes the material to move to the other side, and pushes the bulk material out at the discharge port to complete the discharge, and start the power mechanism 6, so that the power mechanism 6 drives the rotating part 5 to rotate, and the rotating rod 51 drives the cleaning assembly 4 to rotate in the distribution assembly 3, and when the cleaning brush 43 rotates to be symmetrically distributed at the upper and lower positions, the elastic cleaning brush 43 extends from the adapter 32 and rubs the chain surface under the rotation effect. and gaps for cleaning, and at the same time, the air supply unit 7 is started, and the air pump 71 inputs pressurized air into the rotating rod 51 through the control valve 72 and the connecting cover 73, and the pressurized air is input into the internal cavity 42 through the No. 1 port 52 and the No. 2 port 53, and is blown out through the gap between the air outlet 44 and the cleaning brush 43, and the blown air acts on the chain along the upper and lower points to complete the comprehensive cleaning, and as the rotation continues, the cleaning brush 43 rotates and squeezes into the distribution cover 31, and the dust inside the cleaning brush 43 itself is separated, and when the air outlet 44 rotates to a horizontal position and is connected with the bypass port 33, the input air is blown out laterally through the bypass port 33, and is blown toward the sprocket on one side by wind force, and the surface temperature of the sprocket is reduced.

[0040] Firstly, by utilizing the rotational coordination of the distributing assembly component 3 and the cleaning component 4, and utilizing the rotating part 5 to drive the cleaning component 4 to rotate, pressurized air is continuously input into the cleaning component 4, thereby utilizing the cleaning brush 43 and the air outlet 44 in the cleaning component 4 to intermittently perform friction cleaning on the internal gap of the chain during the rotation process, and simultaneously blow it, so as to clean and separate the blocked material from the chain for some bulk transport materials, and avoid the brittle material being squeezed and crushed at the sprocket by the chain's own gap, thereby improving the conveying quality and avoiding excessive crushing of the material. On the other hand, it avoids the material with too high hardness from being conveyed to the sprocket for squeezing, thereby improving the protection of the sprocket, improving the safety during the conveying process, and achieving the quality of material conveying, with good use effect.

[0041] In addition, by again utilizing the relative position change of the distributing assembly component 3 and the cleaning component 4, when the bypass port 33 is connected to the air outlet 44, lateral air blowing is achieved, and in conjunction with the bypass port 33 that is directionally opened on one side of the sprocket, wind blowing is intermittently performed toward a group of sprockets during the conveying process to achieve cooling treatment, avoid excessive heat distribution between the sprocket and the chain during long-term conveying, achieve effective cooling, reduce the impact of heat on the sprocket, and avoid the impact of high temperature on the conveyed material.

[0042] Embodiment 2: After the conveying is completed, the chain is kept running, the control valve 72 in the air supply part 7 is started, the ventilation direction is switched, and the air pump 71 inputs the pressurized air into the mounting seat 8 through the connecting pipe 74. The pressurized air enters the mounting hole 82 through the air channel 84 and pushes the vibration component 9 to move horizontally. The spring 94 is stretched, and the push plate 93 pushes the elastic rod 92 to move upward, so that the impact ball 91 moves upward and is inserted between the adjacent scraper components 2. As the scraper component 2 rotates and pushes the impact ball 91, the impact ball 91 is pushed to drive the elastic rod 92 to bend. When the scraper component 2 passes over the impact ball 91, the elastic rod 92 quickly elastically resets, drives the impact ball 91 to swing back and reset, and collides with the next group of scraper components 2. The collision vibration causes the conveying powder attached to the surface of the scraper component 2 to detach, and then cooperates with the control valve 72 to reintroduce the pressurized air into the cleaning component 4, and intermittently inputs the pressurized air directly into the shell 1. The intermittently blown air drives the powder detached from the vibration to be blown out, completing self-cleaning.

[0043] First, by utilizing the air supply effect of the air supply part 7 again and coordinating with the reversing action, pressurized air is introduced into the mounting seat 8, and the movement of the vibration assembly 9 distributed up and down is promoted, so that the impact ball 91 moves and is inserted between the scraper assembly 2, and the elastic action of the elastic rod 92 is cooperated, and the scraper assembly 2 is used to push the impact ball 91 to follow the elastic rod 92 completely, and then the elastic resetting elastic rod 92 is used to drive the impact ball 91 to reverse reset and hit the scraper assembly 2 at the rear, so as to realize the impact vibration, and vibrate and separate the dust material attached to the surface of the scraper assembly 2, and cooperate with the reversing input of the pressurized air into the cleaning assembly 4 to blow and sweep the inside of the shell 1, and use the intermittent blasting and intermittent vibration to effectively clean out the attached dust, so as to realize quick and effective self-cleaning.
