Description

Technical Field

[0002] With the development of production technology, the development and application of mechanical equipment in the power, chemical and other industries have brought many conveniences to industrial production. Taking the existing coal transportation system as an example, coal transportation is divided into road transportation, water transportation and train transportation, and train transportation is the main mode of transportation of coal. Train unloaders are widely used in major thermal power plants, chemical plants, etc. The use of train unloaders makes the unloading work basically automated, reduces the labor intensity of workers, and improves production efficiency.

[0003] In the existing coal transportation system, due to the limitations of the unloading principle of the existing unloader, there is a lot of coal left in the corners and under the train, which is difficult to clean manually. The unloading process, from opening the door to closing the door after unloading, requires 8-10 people to clean up, and the whole operation process lasts 10 minutes. In addition, the manual cleaning operation environment is very harsh.

[0004] The prior art uses two cleaning turntables with flexible steel wire ropes installed on them. The turntables have a large diameter and a high linear speed, and the residual coal at both ends of the carriage cannot be cleaned effectively. After the cleaning device has been used for a period of time, the flexible steel wire ropes will bend and deform, resulting in poor cleaning effect.

[0005] In summary, it is urgent to propose an efficient bulk material cleaning mechanism to reduce the labor intensity of workers, reduce operating costs, avoid safety hazards, and improve production efficiency. Summary of the invention

[0059] The cleaning mechanism 6 includes two side plates 22, a cleaning motor mounting base 23, a supporting beam 24, a cleaning motor 25, a cleaning disc 26, a lifting shaft 27, a guide shaft 28, a guide wheel 29 and a chain mounting clamp 30.

In this embodiment, in order to solve the problem that the coal at the bottom of the coal transport car is easy to stick / freeze in the cold winter, so that the ordinary cleaning brush cannot effectively clean the frozen coal, the present invention is to improve the cleaning effect of the bottom of the car, the technical solution of the present invention is given below:

The slider 35 is installed on the cleaning scraper 32. The cleaning scraper 32 is slidably installed on the slide rail 34 through the slider 35. A first intersection seat 36 is installed in the middle position of the supporting beam 24. A second articulated seat 37 is installed on the cleaning scraper 32.

The front scraper, two large-diameter cleaning discs with counterweights, and the rear scraper complete six cleaning operations at one time. At the same time, the cleaning disc with a large diameter and an increased counterweight ring rotates to generate a large centrifugal force. Under the action of this centrifugal force, the material is discharged from both sides of the car along the rotation direction of the cleaning disc. At the same time, a plow-shaped guide plate is arranged on the scraper to reduce the dead angle of the material between the discs.

[0064] During the working process, each set of cleaning machinery scrapes one layer from the front, one layer from the two cleaning discs, and one layer from the back, completing the cleaning operation of three layers in one operation process, making the cleaning more efficient. At the same time, the weight ring and diameter are increased on the cleaning turntable to effectively increase the cleaning efficiency. The scraper is equipped with a plow-shaped scraper device, and there are two sets of cleaning mechanisms at the same time, which can more effectively improve the cleaning efficiency.

[0065] The scraper cooperates with the cleaning disc, adopting a structure of two cleaning discs and two scrapers to realize the working mode of cleaning first and scraping later.

[0066] Specific implementation method seven: refer to FIG. Figure 7-10 , explaining this embodiment, in this embodiment, the cleaning scraper 32 has a plow-shaped guide plate 38, and the plow-shaped guide plate 38 is arranged in the middle of the cleaning scraper 32. In this way, the plow-shaped guide plate 38 can more smoothly complete the coal scraping work. When the coal seam is sticky, the plow-shaped guide plate 38 plows up the coal seam, and the scraper makes the coal scraping and cleaning effect more significant.

[0067] Specific implementation method eight: refer to Figure 7-Figure 8 , describing this embodiment, in this embodiment, the cleaning scraper 32 is provided with a plow-shaped guide plate 38, and the plow-shaped guide plate 38 is arranged in the middle position of the cleaning scraper 32. During the cleaning operation, the cleaning mechanism 6 works in the middle position of the carriage, and the plow-shaped guide plate 38 plows the coal seam at the center position of the bottom of the carriage, so that the coal material is scattered, which is convenient for cleaning.
