CN201313744Y - Adjustable Belt Cleaner - Google Patents

Abstract

The utility model relates to an adjustable belt cleaner, in which two ends of a guard plate equipped with an integral belt brush are respectively connected with a threaded rod, and the two threaded rods are movably connected to a connecting plate welded on the belt rack at the lower part of the supporting roller through threads. ; The shaft of the screw rod is covered with a spring, and the upper end is provided with a rotary wrench. Due to the use of an integral belt brush, the problem of the belt brush falling off and scratching the belt is avoided. Through the screw spring and the rotating wrench, the position of the belt brush can be adjusted at any time to prevent the gap between the belt brush and the belt and ensure the cleaning effect. In this way, the phenomenon of coal sprinkling is eliminated, the accuracy of coal blending is improved, the workload of cleaning residual coal is reduced, the problems of belt deviation, residual coal crowding idlers and belt scratches are avoided, and the service life of the belt is improved. Reduced accident losses.

Description

Adjustable Belt Cleaner

technical field

The utility model belongs to the field of belt transportation equipment, in particular to a belt cleaning device for conveying bulk materials.

Background technique

Various bulk materials are conveyed through the belt conveyor, most of the materials will enter the next process through the feed port, but there are always more or less parts of the materials remaining on the working surface of the conveyor belt, such as the belt for transporting coal, there will always be There is residual coal adhering to the belt. When the working surface on the belt with residual coal adhered to the bottom of the head roller, if there is no good cleaning device, the residual coal will fall to the ground, and the residual coal will fall to the ground. cause many adverse consequences. Most of the currently used belt cleaners are fixed non-adjustable belt cleaners, and the belt brushes are split, that is, the cleaners composed of multiple small belt brushes are fixed by a long shaft, and the cleaners and belts are connected by counterweights on both sides. The bottom stubble working face is in close contact. However, the gap between the cleaner and the bottom stubble of the belt is adjusted by the counterweight, because the contact is not tight enough, so the cleaning effect is not good. Especially when the belt brush is worn out, the gap between the two is even bigger. Because it is not adjustable, it is very easy to cause the belt to deviate. One is to increase the wear of the belt and shorten the service life of the belt; It affects the accuracy of coal blending, and increases the workload and labor intensity of operators to clean up the site; what's more, it will squeeze the idler rollers, causing scratches on the belt. In addition, once the small belt brush on the cleaner falls off, the cleaner frame will easily scratch the belt, affecting safety and smooth production.

Contents of the invention

The purpose of this utility model is to overcome the above-mentioned defects, aiming at providing an integrally adjustable belt cleaner with thorough cleaning, adjustable clearance, avoiding deviation, and long service life. Its technical solutions are:

The adjustable belt cleaner is composed of a belt brush, a guard plate, a connecting plate, a screw rod and a spring; both ends of the guard plate installed with an integral belt brush are respectively connected with a threaded rod, and the two screw rods are connected through threads. It is welded on the connecting plate on the belt rack at the lower part of the idler; the screw shaft is covered with a spring, and the upper end is provided with a rotary wrench.

The beneficial effects of the utility model are:

Due to the adoption of the integral belt brush, the problem of the belt brush falling off and scratching the belt is avoided. Through the screw spring and the rotating wrench, the belt brush can always be closely attached to the belt, and when the belt brush is worn, the position of the belt brush can be adjusted at any time to prevent the gap between the belt brush and the belt and ensure the cleaning effect , put an end to the phenomenon of coal sprinkling, improve the accuracy of coal blending, reduce the workload of cleaning residual coal, avoid the problems of belt deviation, residual coal squeezing idlers and scratching the belt, thus improving the service life of the belt , reducing accident losses.

Description of drawings

The accompanying drawing is a schematic diagram of an adjustable belt cleaner.

Among the figure: 1 is a belt idler, 2 is a belt brush, 3 is a guard plate, 4 is a rotary wrench, 5 is a screw mandrel, 6 is a spring, and 7 is a connecting plate.

Detailed ways

Visible by accompanying drawing, the utility model is made up of belt brush 2, guard plate 3, rotary wrench 4, screw mandrel 5, spring 6 and connecting plate 7. Whole belt brush 2 is positioned at the side lower part of belt idler 1, and two screw mandrels 5 are arranged at the both sides of belt idler 1 separately. The guard plate 3 is made of a long steel plate or angle steel, and an integral belt brush 2 is connected with bolts on one side of the guard plate 3. Rod 5 is connected. Two screw mandrels 5 shafts are covered with springs 6, and the upper ends of the screw mandrels 5 are provided with a rotary wrench. Plate 7 is then welded on the belt frame of belt idler 1 bottom. By pulling the rotary wrench 4, the tightness of the spring 6 can be adjusted, thereby adjusting the gap between the belt brush 2 and the belt.

Claims (1)
