Description

Technical Field

[0001] This utility model belongs to the field of funnel technology, specifically, it relates to a flow-guiding and spill-preventing funnel device. Background Technology

[0002] In bulk material conveying systems, materials enter the lower roller conveyor belt from the upper roller belt surface through a funnel. Existing funnel devices cannot guide the flow, causing materials to flow out from the unloading roller belt surface. During the unloading process, the free impact of materials on the funnel causes relatively severe wear and tear. Moreover, due to the large impact of the materials, dust overflow is quite serious. Therefore, improvements are necessary. Utility Model Content

[0003] To address the aforementioned problems in the prior art, this utility model provides a flow-guiding and spill-preventing funnel device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] As one aspect of this utility model, a flow guiding and spillage prevention funnel device is proposed, which includes: a shell, a discharge channel formed inside the shell, a feed opening formed on one side of the shell, a discharge opening formed at the bottom of the shell, the feed opening being connected to the discharge channel, and the discharge opening being connected to the discharge channel.

[0006] A protective cover is connected to the feed opening. The bottom of the protective cover is open. One end of the protective cover is connected to the feed opening, and the other end of the protective cover is connected to a baffle. A curtain is provided inside the protective cover, and the curtain and the baffle are spaced apart.

[0007] It also includes a flow guiding unit, which is located in the unloading channel and between the feed opening and the discharge opening.

[0008] According to this utility model, the flow guiding unit includes a flow guiding base plate, a support plate is connected to the upper end of the flow guiding base plate, a support shaft is connected to the support plate, the support shaft is rotatably connected to the housing, and the flow guiding base plate can swing relative to the housing with the center line of the support shaft as the fulcrum.

[0009] The flow guiding unit also includes a power unit connected to the housing; the fixed part of the power unit is connected to the housing, and the movable part of the power unit is movably connected to the lower middle part of the flow guiding base plate.

[0010] According to this utility model, the shell has a funnel-shaped structure that is larger at the top and smaller at the bottom.

[0011] According to this utility model, the curtain is parallel to the baffle.

[0012] According to this utility model, the cross-sectional shape of the flow guide plate is arc-shaped.

[0013] According to this utility model, it also includes a support base, which is connected to the flow guide base plate; the movable part of the power unit is movably connected to the support base.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] One embodiment of this application provides a flow-guiding and spill-preventing hopper device, such as... Figures 1-4 As shown, it includes: a housing 1, which has a funnel-shaped structure that is larger at the top and smaller at the bottom; a discharge channel 11 is formed inside the housing 1; a feed opening 12 is formed on one side of the housing 1; a discharge opening 13 is formed at the bottom of the housing 1; the feed opening 12 is connected to the discharge channel 11; the discharge opening 13 is connected to the discharge channel 11; the feed opening 12 covers the discharge end of the roller conveyor belt, so that the material on the roller conveyor belt enters the housing 1 and falls from the discharge opening 13 to a preset position;

[0025] A protective cover 2 is connected to the feed opening 12. The bottom of the protective cover 2 is open. In use, the open protective cover 2 is located above the roller conveyor belt surface to protect the material on the roller conveyor belt surface. One end of the protective cover 2 is connected to the feed opening 12, and the other end of the protective cover 2 is connected to a baffle 3. There is a preset distance between the baffle 3 and the roller conveyor belt surface, that is, the baffle 3 does not come into contact with the material on the roller conveyor belt surface.

[0026] The protective cover 2 is provided with a curtain 4, which is spaced apart from the baffle 3; the curtain 4 is parallel to the baffle 3; the curtain 4 is close to the feed opening 12;

[0027] It also includes a flow guiding unit 5, which is located in the unloading channel 11 and between the feed opening 12 and the unloading opening 13. The flow guiding unit 5 guides the material entering from the feed opening 12 to the unloading opening 13, thereby reducing the direct impact of the material on the shell 1.

[0028] Specifically, in one embodiment, such as Figure 4 As shown, the flow guiding unit 5 includes a flow guiding base plate 51, the cross-sectional shape of which is arc-shaped; a support plate 52 is connected to the upper end of the flow guiding base plate 51, and a support shaft 53 is connected to the support plate 52. The support shaft 53 is rotatably connected to the housing 1, and the flow guiding base plate 51 can swing relative to the housing 1 with the center line of the support shaft 53 as the fulcrum.

[0029] The flow guiding unit 5 also includes a power unit 54 connected to the housing 1. The power unit 54 is an electric push rod. The structure of the electric push rod is existing technology, and its principle is similar to that of a hydraulic cylinder, which will not be described in detail here. The fixed part of the power unit 54 is connected to the housing 1, and the movable part of the power unit 54 is movably connected to the lower middle part of the flow guiding base plate 54, so that the angle of the flow guiding base plate 54 relative to the housing 1 can be adjusted to adapt to the impact angle of different materials.

[0030] In one embodiment, a support base 55 is also included, which is connected to the flow guide base plate 51; the movable part of the power unit 54 is movably connected to the support base 55 by a pin, which facilitates the angle adjustment of the flow guide base plate 51.

[0031] In one embodiment, a device bracket 14 is connected to the housing 1, and the device bracket 14 is used to support the housing 1.

[0032] In order to prevent the protective cover 2 from being suspended above the roller tape surface, a protective cover bracket 21 is connected to the protective cover 2 to support the protective cover 2.

[0033] In one embodiment, the housing 1 is provided with an observation window 15 to facilitate observation of the unloading situation inside the housing 1.

[0034] In summary, this application uses the curtain 4 and the baffle 3 to separate the shell and the protective cover into two areas: a discharge area and a flow-guiding sealed area. Since the material always flows to the discharge channel, there is a pressure difference between the discharge channel and the flow-guiding sealed area. Due to the presence of the pressure difference, the overflow of material dust is suppressed. The use of an arc-shaped flow-guiding base plate and an electric push rod reduces the impact and wear of the material on the shell.
