Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, and more particularly to a chute. Background Art

[0002] Belt conveyors are essential transportation equipment in industries such as metallurgy, coal, building materials, and chemicals. They function by transferring material from the incoming belt conveyor through a hopper and chute at the top, smoothly and quickly unloading it onto the receiving belt conveyor below, where it is then transported to the desired location. In practice, multiple belt conveyors are deployed, allowing materials to be stored in silos or transported directly to processing areas for further processing.

[0003] Currently, there are three main types of chutes between belt conveyors: the first is the direct connection chute, the second is the curved chute, and the third is the multi-step chute. The direct connection chute directly connects the discharge point and the receiving point using a cylinder (with an internal liner) according to the process layout. It features a simple design, easy manufacturing, and installation. However, its disadvantages are a short chute lifespan, susceptibility to material blockage or impact on the receiving belt, and high maintenance costs. The curved chute is a more ideal connection method, with advantages such as reduced dust, reduced material impact, and significantly increased chute lifespan. However, its disadvantages are a longer design cycle, greater manufacturing difficulty, and higher requirements for the manufacturing plant. The third type is the stepped chute. This chute is designed with multiple transition steps between the two belt conveyors based on material parameters to facilitate material collection, forming a natural accumulation of materials, which then flow along the material surface. The stepped chute has low manufacturer requirements and is relatively easy to install. However, material wear remains a problem that affects the service life of stepped chutes.

[0034] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0035] As shown in Figure 1 and Figure 2 The utility model discloses a chute, including head funnel 100, chute body 200 and follow the flow chamber 300, three are communicated in proper order.

[0036] Among them, the chute body 200 includes the first body section 210 and the second body section 220 of intercommunication, the first body section 210 is communicated with the head funnel 100, and the first body section 210 is provided with a lining plate, and the lining plate is preferably a wear-resistant lining plate. The material of the lining plate can be selected from alloy material, ceramic material or high polymer material, and the actual demand can be determined specifically. The second body section 220 is provided with a plurality of step structures 221, and the adjacent two step structures 221 form a first hopper. A plurality of first hoppers form a first hopper assembly. The second body section 220 can also be provided with a lining plate.

[0037] For example, when the chute is located between the unloading belt conveyor and the receiving belt conveyor, the material from the unloading belt conveyor first enters the head funnel 100, then enters the chute body 200, and then flows into the follow-flow chamber 300. After accumulation, it falls to the receiving belt conveyor.

[0038] The chute disclosed in the embodiments of the present application is provided with a lining plate in the first body section 210, which can reduce the wear of the first body section 210. The second body section 220 is provided with a plurality of step structures 221 to form a first hopper. When the material reaches the second body section 220, the material is accumulated in the first hopper. When the first hopper accumulates a certain amount of material, a material surface is formed, and the following material runs along the material surface. The second body section 220 can reduce impact wear under the protection of the material surface, thereby reducing the wear of the material on the chute body 200 and prolonging the service life of the chute body 200.

[0039] It should be noted that the chute body 200 can be made of steel plates and welded together. In order to facilitate installation, the chute body 200 can be divided into multiple segments connected in sequence, preferably connected by flanges.

[0040] Further, as shown in Figure 3As shown, in some specific embodiments, the step structure 221 includes a step platform 2211 and a step upright 2212, the step upright 2212 and the step platform 2211 are connected, and the height of the step upright 2212 is higher than the step platform 2211, so that a first material box is formed between two adjacent step uprights 2212. The cavity enclosed by the two adjacent step uprights 2212 and the step platform 2211 shown in the figure is the first material box, and the upper part of the cavity is represented by a dotted line.

[0041] It should be noted that the step platform 2211 is preferably arranged in the horizontal direction, and the step upright plate 2212 is preferably arranged in the vertical direction. Of course, the step platform 2211 and the step upright plate 2212 can also be arranged at an angle, as long as it can be ensured that the two adjacent step upright plates 2212 can form a first material box, so that the material is accumulated to form a material surface, which can reduce the wear and friction of the material on the second main body section 220.

The material runs along this material surface, and the step plate 2212 is worn first. The staff needs to perform appropriate maintenance on it during maintenance and inspection. If the step plate 2212 is damaged, the triangular cavity (i.e., the step structure 221) formed by the step plate 2212 and the step platform 2211 acts as a third material box and first contacts the material. The staff can inspect and maintain the step structure 221 to extend the service life of the chute; after the step structure 221 is worn, the material directly contacts the second body section 220. The chute disclosed in the embodiment of the present utility model provides a two-level wear-resistant protection measure through the setting of the step structure 221, which reduces the direct contact of the material with the second body section 220, can reduce the wear of the second body section 220, and thus extend the service life of the chute.

[0043] Furthermore, in some specific embodiments, the step platform 2211 and the step riser 2212 are both connected to the second body section 220, and for two adjacent step structures 221, it is preferred that the step riser 2212 of one step structure 221 abuts against the step platform 2211 of the other step structure 221, as shown in FIG.
