Description

Technical Field

[0001] The utility model relates to the technical field of cleaners, in particular to a belt cleaner. Background Art

[0002] During the process of a belt conveyor transporting materials, if the residual adhered materials enter the drum or the idler bearing housing, it will accelerate the bearing wear. If the surface of the drum or the idler is adhered with materials, it will tear and fluff the surface rubber of the conveyor belt, accelerating the wear and damage of the conveyor belt. Therefore, a cleaner is needed to clean the materials adhered to the return belt. For the cleaners in the prior art, their blades are made of polyurethane materials, and springs are used to press the blades on the belt at the head roller of the belt conveyor. Since polyurethane is easy to wear, when the blades are worn, the pressure will become smaller. Therefore, it is often necessary to adjust the pressure of the springs, which is rather troublesome. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a belt cleaner aiming at the above-mentioned existing technical deficiencies.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a belt cleaner, including two mounting seats which are respectively arranged at the left and right ends of a cross beam. A plurality of sliding seats capable of sliding in the front-back direction are slidably connected to the cross beam. Blades are arranged on the sliding seats, and a plurality of cylinders are also arranged on the cross beam for respectively pushing the plurality of sliding seats so that the blades contact the belt with a certain force.

[0005] Further optimizing the technical solution, guide posts are arranged on both sides of the sliding seat, the extending direction of the guide posts is the front-back direction, and guide holes matching with the guide posts are arranged on the cross beam.

[0006] Further optimizing the technical solution, a groove is arranged on the bottom surface of the cross beam, the cylinders are arranged in the groove, and a notch is arranged at the corresponding position on the front side of the cross beam.

[0007] Further optimizing the technical solution, a rectangular channel is arranged on the mounting seat, the end of the cross beam extends out of the rectangular channel and the two are slidably connected. A screw barrel is arranged on the front side of the cross beam, a side plate is arranged on the front side of the mounting seat, a through hole is arranged on the side plate, and a bolt passes through the through hole and is connected with the screw barrel.

[0008] Compared with the prior art, the utility model has the following advantages: the blades are arranged on the sliding seats, and the sliding seats are slidably connected to the cross beam. The cross beam is also provided with cylinders capable of driving the sliding seats to move forward, so that when the blades are worn, they can still contact the belt with a constant force, and there is no need to frequently adjust the pressure as in the prior art, which is rather convenient.

[0013] To make the objectives, technical solutions and advantages of the present utility model clearer and more obvious, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0014] Specific embodiments: As shown in Figures 1 - 3 , a belt cleaner includes two mounting seats 1, which are respectively arranged at the left and right ends of a cross beam 2. A plurality of sliding seats 3 capable of sliding in the front-rear direction are slidably connected to the cross beam 2. A blade 4 is arranged on the sliding seat 3, and the material of the blade 4 is polyurethane. A plurality of cylinders 6 for respectively pushing the plurality of sliding seats 3 so that the blade 4 contacts the belt with a certain force are also arranged on the cross beam 2. As long as the pressure of the air source supplying air to the cylinder 6 remains constant, the thrust provided by the cylinder 6 is also constant. As the blade 4 gradually wears, the part of the piston rod of the cylinder 6 extending out of the cylinder 6 will become longer and longer, so that the blade 4 always contacts the belt with a constant force, without the need for frequent adjustment as in the prior art. When there are stubborn foreign objects on the belt and they cannot be scraped off, since the gas in the cylinder 6 can be compressed, the blade 4 and the sliding seat 3 can be pushed backward by the foreign objects to make a concession. Since there are a plurality of blades 4, when a certain blade 4 retreats, the other blades 4 will still contact the belt to perform the cleaning work.

[0015] Specifically, guide posts 31 are arranged on both the left and right sides of the sliding seat 3. The extending direction of the guide posts 31 is the front-rear direction. Guide holes 23 matching the guide posts 31 are arranged on the cross beam 2, thereby realizing the sliding connection between the sliding seat 3 and the cross beam 2.

[0016] Specifically, a groove is provided on the bottom surface of the cross beam 2, so that its cross section is in a groove shape. The air cylinder 6 is arranged in the groove. A notch 22 is provided at the front side of the cross beam 2 at a position corresponding to the air cylinder 6. Preferably, the cross section of the lower part of the sliding seat 3 is also in a groove shape. The sliding seat 3 is buckled on the cross beam 2. The piston rod of the air cylinder 6 passes through the notch 22 and is connected to the front part of the sliding seat 3.

[0017] Preferably, a rectangular channel 12 is provided on the mounting seat 1. The end of the cross beam 2 extends out of the rectangular channel 12 and the two are slidably connected. A screw cylinder 21 is provided on the front side of the cross beam 2. A side plate 11 is provided on the front side of the mounting seat 1. A through hole is provided on the side plate 11. The bolt 5 passes through the through hole and is connected to the screw cylinder 21, so that the front and rear positions of the cross beam 2 can be adjusted.

[0018] The blade 4 is detachably connected to the sliding seat 3. When the blade 4 is worn too severely and cannot be used, the piston rod of the air cylinder 6 is operated to retract, and then the blade 4 can be replaced. After the replacement is completed, the piston rod of the air cylinder 6 is operated to extend so that the head of the blade 4 contacts the belt.

[0019] The above embodiments only describe the preferred implementation schemes of the present invention, and do not limit the protection scope of the present invention. Without departing from the design spirit of the present invention, any deformation and improvement made by those of ordinary skill in the art to the technical solution of the present invention shall fall within the protection scope of the present invention.
