Description

Prevent pressing from both sides material impact idler

Technical Field

The utility model relates to a mechanical equipment technical field, concretely relates to prevent pressing from both sides material impact idler.

Background

The impact idler is an important part commonly used on a conveyor, for example, on engineering machinery such as a mobile crushing station, a cold road milling machine and the like, the impact idler is arranged on the lower surface of an upper belt of the conveyor, and plays roles of buffering and supporting the conveyor belt. Fig. 4 shows a prior art impact idler, and a rubber body is disposed at the outermost layer of the impact idler, and the rubber body is generally formed by butt-jointing and sleeving a plurality of original rubber rings 2 a. When the mechanical equipment works, the impact of the lump materials is often applied to the impact carrier roller, the lump materials are clamped in the cracks among the original rubber rings 2a of the rubber body, and if the lump materials are not cleaned in time, the stable matching between the impact carrier roller and the conveying belt is influenced, so that the conveying belt is deviated, and even the conveying belt is scratched. Because the space that above-mentioned mechanical equipment installation used snub pulley is fairly narrow and small and compact, carry out the maintenance, the change of bearing roller, the clearance is very inconvenient or be difficult to realize, needs to spend a large amount of time and manpower under the general condition and dismantles to get off and handle, has seriously influenced engineering machinery equipment's production efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a novel prevent pressing from both sides material impact idler to solve the problem of centre gripping lump material between the rubber circle.

In order to realize the purpose, the utility model discloses a prevent pressing from both sides material snub pulley, including steel pipe body and steel axle, the steel axle is fixed to be set up the both ends center department of steel pipe body the outer surface cover of steel pipe body is equipped with a plurality of rubber circle, the surface of perpendicular to steel pipe body is followed on the both sides of rubber circle, closely cooperate between the rubber circle the V-arrangement slot has been seted up on the rubber circle.

The rubber ring is characterized by further comprising a scraping plate fixedly connected with the steel shaft and positioned below the steel shaft, round holes are formed in two sides of the scraping plate, a hollow portion is formed between the round holes, and the edge line of the hollow portion is attached to the shape of the rubber ring.

Furthermore, a through hole is formed in the steel shaft, the through hole is matched with the round hole in the scraping plate, and the scraping plate is fixedly connected with the steel shaft through a bolt.

The utility model has the advantages that: through set up V-arrangement slot on the rubber ring, when the cushion idler when having the lump material contact, the lump material often can not form the centre gripping relation in V-arrangement slot, and the lump material can break away from cushion idler immediately like this, and can not exert an influence to the conveyer belt. The scraping plates are arranged on the buffer carrier roller, and when the lump materials are clamped in the V-shaped grooves occasionally, the lump materials can be cleaned by the scraping plates in the rotating process of the buffer carrier roller, so that the smooth operation of the belt is ensured.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-3, the anti-pinch buffer roller of the embodiment includes a steel tube body 1 and a steel shaft 3, the steel shaft 3 is fixedly disposed at the centers of two ends of the steel tube body 1, and the steel tube body 1 uses the center line of the steel shaft 3 as a rotation axis. The outer surface cover of the steel pipe body 1 is equipped with a plurality of rubber circle 2, the surface of the perpendicular to steel pipe body 1 is followed on the both sides of rubber circle 2, when rubber circle 2 combines together, can reach closely the cooperation, thereby can prevent the centre gripping lump material between rubber circle 2, V-arrangement slot 200 has been seted up on rubber circle 2, the slope of this kind of V-arrangement is great, be in order to prevent the lump material centre gripping in the inside, the surface area of rubber circle 2 has also been reduced simultaneously, also can reduce the chance of bonding or centre gripping lump material like this.

As shown in fig. 3, in order to further prevent and treat the lump materials clamped on the rubber ring, the material clamping preventing impact idler of the embodiment further comprises a scraper plate 5, and the scraper plate 5 is installed at a position below the steel shaft 3 and vertical to the ground. The steel shaft 3 is provided with a through hole 4, the through hole 4 is matched with a round hole on the scraping plate 5, and the scraping plate 5 is fixedly connected with the steel shaft 3 through a bolt. A hollow part 6 is arranged between the round holes, the edge line of the hollow part 6 is attached to the shapes of the rubber ring 2 and the steel pipe body 1, only a small gap exists in the middle, when the steel pipe body 1 rotates, the steel pipe body 1 and the rubber body 2 just penetrate through the hollow part 6, and when lump materials are clamped on the rubber ring 2, the lump materials can be scraped off by the outer edge of the hollow part 6, so that the cleaning purpose is realized. Because the scraping plate 5 is arranged perpendicular to the ground, the lump material scraped from the rubber ring 2 directly falls down without depositing on the scraping plate 5, so that the secondary cleaning of the scraping plate 5 is avoided. The material of the scraping plate 5 is nylon sheet or steel sheet.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes that can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art can be made within the scope of the claims of the present invention.
