Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal conveying equipment, in particular to a coal conveying device with adjustable inclined chute and anti-blocking function. BACKGROUND

[0002] The coal conveying device with adjustable inclined chute and anti-blocking function is mainly applied to coal conveying scenes such as coal transfer in thermal power plants, raw coal loading in coal mines and coal loading and unloading in ports. In these scenes, the coal conveying system needs to be connected to different height material receiving equipment such as coal bunkers, transfer belts and transport vehicles. The inclination angle of the coal conveying chute directly affects the smoothness of coal conveying and is one of the core structures for ensuring the efficiency of coal conveying and avoiding coal leakage.

[0003] At present, the commonly used coal conveying chute devices in the industry mainly adopt two types of inclination angle adjustment structures. One type is a fixed inclination angle chute which is fixedly installed through a pre-set rigid support frame. The inclination angle is determined in the production and manufacturing stage and cannot be flexibly adjusted according to the height change of the material receiving equipment. It can only adapt to a single coal conveying scene. The other type is a manually adjustable chute which requires an operator to loosen the fastening bolts of the support structure with a wrench and manually bend the main body of the chute to the target angle before re-tightening the bolts to fix the inclination angle. These existing devices have obvious deficiencies. The adaptability of the fixed inclination angle chute is very poor. When the height of the material receiving equipment changes, different specifications of the chute need to be replaced. This not only makes the operation cumbersome but also greatly increases the equipment procurement and storage costs. The adjustment process of the manually adjustable chute is complex and requires multiple people to work together. The adjustment takes a long time and seriously disrupts the continuity of the coal conveying operation. Moreover, the inclination angle stability after the bolt fastening is poor. The inclination angle may deviate during the coal conveying process due to the impact force of the coal, which leads to deviation of the coal conveying track from the material receiving area, causing coal leakage and poor conveying.

[0004] Therefore, the coal conveying device with adjustable inclined chute and anti-blocking function is proposed to solve the above problems. SUMMARY

[0036] One end of the spring 19 is fixedly connected to the bottom inner wall of the cavity 17, the other end of the spring 19 is fixedly connected to the outer part of the sliding plate 20, the top of the plurality of dampers 18 is fixedly connected with the sliding plate 20, which realizes the effect of connecting the damper 18 and the cleaning plate 21, transmitting the coal pressure received by the cleaning plate 21, and driving the damper 18 and the spring 19 to produce elastic deformation, the outer part of the sliding plate 20 is slidably connected to the inner part of the cavity 17, the top of the sliding plate 20 is fixedly connected with the cleaning plate 21, which realizes the effect of close contact with the bottom of the working shell 4, scraping the accumulated coal on the surface of the conveying belt 5, dredging the coal conveying track, and avoiding the coal blocking situation, and the top of the cleaning plate 21 is in contact with the outer part of the working shell 4.

[0037] Working principle: when the device is used, first of all according to the height of the material receiving equipment corresponding to this time coal conveying operation, the chute inclination requirement of coal conveying, start the motor 8, the output end of the motor 8 drives the threaded rod 9 to rotate synchronously; because the sliding block 10 is threadedly connected with the threaded rod 9, the sliding block 10 will move horizontally along the internal track of the shell 6, at the same time the sliding rod 11 outside the sliding block 10 slides along the track of the sliding hole 7 synchronously; during the movement of the sliding rod 11, the power plate 12 outside it changes the angle, thereby driving the fixed plate 13 at the bottom of the working shell 4 to move synchronously, so that the working shell 4 rotates around the outside of the fixed rod 2, the operator can observe the inclination degree of the working shell 4, and after adjusting it to the target inclination angle that meets the current coal conveying requirement, the motor 8 is turned off, at this time the inclination angle of the working shell 4 is fixed, and the subsequent coal conveying track is adapted.

[0038] After the inclination angle adjustment of the working shell 4 is completed, the electric push rod 15 is started, the output end of the electric push rod 15 pushes the containing shell 16 to move along the track of the guide rod 22 towards the bottom of the working shell 4, until the top of the cleaning plate 21 closely contacts with the bottom surface of the working shell 4; at this time the damper 18 and the spring 19 in the cavity 17 inside the containing shell 16 are still in the natural state, the sliding plate 20 remains in the initial position inside the cavity 17, and the cleaning plate 21 has been in the standby state and can clean the surface of the transmission belt 5 during the coal conveying process, so as to prepare for the anti-blocking coal operation.

[0039] After confirming that the inclination angle of the working shell 4 and the state of the cleaning component are appropriate, the driving assembly is started, the rotating rod 24 in the driving assembly drives the power roller 25 to rotate synchronously, and the power roller 25 drives the transmission belt 5 outside the sleeve to start circulating during the rotation process, the transmission belt 5 maintains a stable rotation rate, at this time the transmission belt 5 has the power condition to convey coal, and waits for the coal feeding operation.

[0040] The coal to be conveyed is evenly laid on the top area of the transmission belt 5, and the coal is moved to the right side of the working shell 4 during the operation of the transmission belt 5, so as to realize the continuous conveying of the coal; in this process, the detector 23 is continuously in the working state, and the coal distribution on the surface of the transmission belt 5 is monitored in real time, and once the coal accumulation trend is found, feedback can be provided in time for the subsequent cleaning adjustment.

[0041] In the process of conveying coal by the conveying belt 5, the cleaning plate 21 always keeps in close contact with the bottom of the working shell 4. When the coal is accumulated on the surface of the conveying belt 5 and is about to form a coal blockage, the cleaning plate 21 will be pressed by the coal, and then the sliding plate 20 is pushed to move to the bottom of the cavity 17. At this time, the damper 18 and the spring 19 will be elastically deformed to buffer the pressure received by the cleaning plate 21, and at the same time, the cleaning plate 21 always closely contacts the bottom of the working shell 4 to scrape and dredge the accumulated coal on the surface of the conveying belt 5, so as to avoid the coal blockage on the conveying belt 5. If the detector 23 feeds back that the coal accumulation is more serious, the position of the containing shell 16 can be adjusted by adjusting the output stroke of the electric push rod 15, so as to finely adjust the cleaning range of the cleaning plate 21 to cover the coal blockage area of the conveying belt 5.
