Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coal preparation machines, in particular to a feeding mechanism for a coal preparation machine. Background Art
[0002] Coal preparation is also called coal washing, which is the process of selecting clean coal that meets the quality requirements of users from raw coal. Coking coal has certain requirements for ash and sulfur content, and clean coal that has been washed must be used. The petrographic composition of coal and the quantity, type, nature and distribution of minerals in coal are all factors that affect the selectability of coal. In the process of coal preparation, feeding is indispensable.
[0003] The existing coal preparation machine feeding mechanism cannot screen the coal, which results in the unqualified coal also entering the screening process, which is ineffective and the quality cannot be guaranteed. Utility Model Content

[0007] Furthermore, a plurality of connecting frames are provided in the frame, and the plurality of connecting frames are respectively fixed between two adjacent groups of screen meshes.
[0008] The beneficial effects achieved by the utility model using the above structure are as follows:
[0009] 1. The design of screen, baffle and electric push rod helps to achieve coal screening. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:
[0011] Figure 1 It is a schematic diagram of the overall structure of the feeding mechanism of the coal preparation machine of the utility model.
[0012] Among them, 1. frame, 2. moving seat, 3. pulley, 4. collecting box, 5. feeding port, 6. screen, 7. baffle, 8. top bracket, 9. electric push rod, 10. connecting frame, 11. belt conveyor. DETAILED DESCRIPTION
[0013] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0014] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0015] In one embodiment, Figure 1 As shown, the feeding mechanism of the coal preparation machine of the utility model includes a frame 1, a moving seat 2, a pulley 3, a collecting box 4, a screen 6, a baffle 7, a top bracket 8 and an electric push rod 9. The moving seat 2 is located in the frame 1, the pulley 3 is rotatably arranged on the side of the moving seat 2 and rolls in the frame 1, the collecting box 4 is provided with a plurality of groups, and the plurality of collecting boxes 4 are all arranged on the moving seat 2, the screen 6 is provided with a plurality of groups, and the plurality of screens 6 are tilted and fixed in the frame 1, the baffle 7 is provided with a plurality of groups, and the plurality of baffles 7 are one-to-one fitted on one side of the plurality of groups of screens 6, the top bracket 8 is fixed in the frame 1, the electric push rod 9 is provided with a plurality of groups, and the plurality of electric push rods 9 are fixedly connected with the plurality of baffles 7 one-to-one.
[0016] A feed port 5 is provided on the top of the frame 1, and a belt conveyor 11 is fixedly provided on the top of the frame 1. A plurality of connecting frames 10 are provided in the frame 1, and the plurality of connecting frames 10 are fixedly provided between two adjacent sets of screen meshes 6, respectively.
[0017] When used, coal enters the feed port 5 through the belt conveyor 11 and falls onto the topmost screen 6. Coal particles with smaller particle sizes fall from the screen 6 and enter the collection box 4 directly below. The electric push rod 9 contracts, so that the baffle 7 is away from the screen 6, and the coal that fails to pass through the screen 6 slides down and tilts onto the screen 6 below, and is screened again by the screen 6 below. Thus, coal with different particle sizes is collected in different collection boxes 4.
[0018] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0019] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.

Any figure mark in the claims should not be regarded as limiting the claims involved.
[0020] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
