Description
[0001] Technical field.
[0002] The utility model relates to technological processes and transportation of materials, namely to buckets for bucket conveyors for continuous vertical-horizontal movement of bulk materials.
[0003] Prior art.
[0004] Currently, manufacturers offer various types of bucket conveyors for various types of products (food, chemical, agricultural, etc.). They are generally made of polymer or metal.
[0005] Depending on the type of product, consumers have corresponding requirements for bucket conveyor buckets: impact resistance, no bending of the leading edge, a certain lifting capacity, long service life, etc.
[0006] Although there is a wide variety of buckets for bucket conveyors on the market, they have a number of disadvantages, such as bulk products sticking to the walls or bottom of the bucket, which reduces the efficiency of transporting products through the elevator, low strength of the bucket itself and breakage at the points where the bucket is attached to the conveyor.
[0007] From the prior art, designs of buckets for conveyors of various types of products are known (for example, according to patents No. CA2459366A1 "Bucket for a bucket elevator", No. GB2570007A "Elevator Buckets)), No. US10961056B2 "Elevator buckets)) etc.), however, all of them are made only from a polymer material, which has a lower level of rigidity and strength in comparison with a product in which the polymer material is reinforced, for example, with fiberglass, as in the present technical solution.
[0008] The prior art also includes conveyor buckets with varying hole diameters for mounting the buckets (see, for example, https: / / iem-group.ru / news / stati / polnoe-rukovodstvo-po-ustanovke-i-zamene-noriza.tvazh.ki / ). However, these hole diameters are quite small (typically 8 to 10 mm) and are secured with a single fastener, increasing the risk of the bucket breaking off the conveyor during use.
[0009] The stated technical solution is aimed at solving the indicated shortcomings.
[0010] Disclosure of the essence of the utility model.
[0011] The technical objective of this utility model is to create a bucket design with improved performance characteristics (namely, increasing the reliability and efficiency of transporting bulk materials).
[0012] The technical result of the claimed utility model is the achievement of the specified technical task.
[0013] The technical result is achieved due to the fact that the bucket has a body in the form of a U-shaped trough with side walls, a bottom and a flange edge, characterized in that the body is made of a composite polymer material reinforced with fiberglass with a roughness of the inner surface of the body of less than 0.4 μm, and in the bucket fastening area there is a metal sleeve for a radial ball bearing, which is fastened with two retaining rings.
[0014] Adding fiberglass (15% by weight) to the polymer material during the manufacture of the bucket allows for an increase in strength (including when exposed to chemicals) and rigidity of the product body by 20%.
[0015] The increased thickness of the body walls (sides - 3.5 mm, bottom - 4.5 mm) of the bucket also allows for increased rigidity and strength of the product.
[0016] The product's operational reliability is also enhanced by a reinforced design for attaching the bucket to the conveyor in the form of a metal sleeve for a radial ball bearing, secured with two retaining rings, which reduces the risk of the bucket breaking off during use on the conveyor.
[0017] The efficiency of transporting bulk products when using the claimed technical solution is also achieved due to the fact that the inner surface of the bucket has a roughness of less than 0.4 μm, which increases the fluidity of the material for which the bucket is used and significantly reduces its adhesion to the surface of the bucket.
[0018] In particular, the inner diameter of the metal sleeve is 20mm, and the outer diameter is 26.5mm, which can significantly strengthen the attachment area of the bucket to the conveyor line.
[0019] Implementation of a utility model.
[0020] The reinforced bucket for a bucket conveyor of bulk products has a body in the form of a U-shaped trough with side walls, a bottom and an edge-flange, characterized in that the body is made of a composite polymer material reinforced with fiberglass with a roughness of the inner surface of the body of less than 0.4 μm, while the thickness of the side walls and the bottom of the body is 3.5 mm, the upper edge-flange is 4.5 mm, and in the fastening area of the bucket there is a metal sleeve for a radial ball bearing, which is fastened with two retaining rings.
[0021] The utility model is implemented as follows:
[0022] This bucket is injection molded from a polymer material containing 15% fiberglass at 260°C, with an internal surface polished with P1500 grit abrasive. It features a radial ball bearing (e.g., 6000-2RS) with a high surface tension (e.g., H7 / m6) secured by two retaining rings (one in the housing and one on the axle). When bulk material is poured into the bucket, it does not stick to the housing walls due to the low surface roughness, improving material flow and conveying efficiency. Fiberglass reinforcement, increased wall thickness, and a reinforced metal bushing ensure a longer service life and improved efficiency.
[0023] Thus, the declared technical solution ensures the achievement of the declared technical result.
