Description

Technical Field

[0001] The utility model belongs to the technical field of transfer equipment, in particular to a scraper device for a bulk cargo transport belt. Background Art

[0002] Conveyor belt, also known as transport belt, is a composite product of rubber, fiber, metal, or plastic and fabric used in conveyor belts to carry and transport materials. It is widely used in cement, coking, metallurgy, chemical industry, steel and other industries where the conveying distance is short and the conveying volume is small.

[0003] The working principle of the conveyor belt is that the driving device tightens the conveyor belt, and through the combined operation of the middle frame and the rollers, the driving device drives the rotating shaft to run, thereby driving the rollers to rotate, and the rollers drive the conveyor belt to circulate through friction to achieve the transportation effect.

[0004] The management of material falling on the return journey of the conveyor belt has always been the focus of process equipment management. If it is not managed properly, it will not only cause a lot of material falling along the return journey of the belt conveyor, which will bring a burden to the cleaning personnel and increase labor costs. In severe cases, the falling materials will wrap around the rollers, causing the rollers to stop rotating and damaging the conveyor belt. In addition, the cleaning of falling materials along the line must be carried out when the conveyor belt is not operating, which also restricts production.

[0005] Nowadays, conveyor belts are equipped with sweepers to centrally control the material falling on the return journey. Some of the materials cleaned by the sweepers will be transported to the cargo stack in the yard along the downstream belt, but most of the materials cannot enter the downstream belt, but are concentrated in a certain place for centralized cleaning. Although centralized cleaning has freed up some manpower, it has not yet achieved the goal of automatic cleaning and automatic recycling to completely free up manpower.

[0006] In order to achieve the above purpose, a new mining device must be designed and installed, which can automatically recycle the materials cleaned up centrally and transport them to the cargo stacking yard along the downstream belt, thus completely eliminating the need for secondary cleaning. Utility Model Content

[0007] In order to solve the problem that the labor intensity is high and the operation efficiency is low when the falling materials on the conveyor belt return journey are cleaned up by manpower, the utility model provides a scraping device for a bulk cargo transport belt.

[0008] The utility model is realized by the following technical solutions:

[0009] A scraper device for a bulk cargo transport belt comprises two tracks 1 arranged in parallel in the same plane, a support rod 1 slidably arranged on the two tracks 1, the support rod 1 contacts the track 1 through a roller, and a scraper plate is arranged on the support rod 1; the scraper plate is rotatably arranged on the support rod 1, and a scraper stopper connected to a scraper moving trolley frame is arranged on the side of the scraper plate close to the pushing hydraulic oil cylinder;

[0010] A hydraulic cylinder capable of pushing the scraper plate to move is provided on one side of the support rod away from the scraping direction of the scraper plate;

[0011] A parallel track 2 is also arranged above the track 1, and the distance between the track 2 and the track 1 is greater than the diameter of the roller.

[0012] The hydraulic cylinder is pushed to push the support rod one to move along the track one. The scraper plate on the support rod one cleans and pushes the material on the conveyor belt. During the pushing process, the scraper plate stopper keeps the scraper plate in contact with the material. During the return process, the scraper plate can be lifted up by the material under the action of rotation to avoid the problem of scraping backwards. When scraping, the scraper plate is lifted up by the material and the roller leaves the track one. The roller can contact the track two to avoid tipping and ensure the scraping effect. Mechanized cleaning is achieved to improve work efficiency.

[0013] A further improvement of the utility model is that the guide surfaces of the track 1 and the track 2 are provided with anti-slip parts matched with the rollers. The anti-slip parts help to prevent the rollers from derailing when moving along the track 1 or the track 2, and help to ensure the normal operation of the scraper.

[0014] A further improvement of the utility model is that the cross section of the anti-slip part is triangular, and the roller is provided with a guide groove matched with the anti-slip part, which is helpful for assembling the roller between the track 1 and the track 2, and can also limit the roller from shaking axially.

[0015] A further improvement of the utility model is that a support rod 2 parallel to the support rod 1 is provided on one side of the scraping direction of the support rod 1, and rollers capable of contacting the track 1 are provided at both ends of the support rod 2; the support rod 1 and the support rod 2 are connected by the support rod 3, and the support rods 1, 2 and 3 form a scraper moving trolley frame. The scraper moving trolley frame helps to enhance the support effect on the scraper.

[0016] A further improvement of the utility model is that the scraper plate is inclined when in contact with the scraper stopper, so as to form a scraping angle for scraping the material during scraping.

[0017] A further improvement of the utility model is that it also includes a scraper device housing with an opening at the bottom, and the track 1 and the track 2 are installed in the scraper device housing, which helps to improve the mobility of the device.

[0018] It can be seen from the above technical scheme that the beneficial effects of the utility model are: the hydraulic cylinder is pushed to push the support rod one to move along the track one, and the scraper plate on the support rod one forms a cleaning push for the material falling on the conveyor belt. During the pushing, the scraper plate stopper keeps the scraper plate in contact with the material. During the return stroke of the scraper plate, it can be lifted up by the material under the action of rotation, thus avoiding the problem of scraping backwards; when scraping, the scraper plate is lifted up by the material and the roller leaves the track one, and the roller can contact the track two, thereby avoiding tipping and ensuring the scraping effect; mechanized cleaning is realized and work efficiency is improved.
