Description

Technical Field

[0001] This utility model belongs to the technical field of vibrating screens, specifically relating to the inlet structure of a vibrating screen. Background Technology

[0002] A vibrating screen is a device that uses a vibrating motor as a vibration source to vibrate the screen inside the screen box to screen materials. During screening, the material falls into the screen surface of the screen box from the feed port. Under the vibration of the inclined screen surface, the material moves. Material particles smaller than the screen hole size pass through the screen hole and become undersize material, while material larger than the screen hole size stays on the screen surface and continues to move forward, and is finally discharged from the discharge port to complete the screening operation. The feeding channel of a vibrating screen is generally a straight cylindrical material pipe or a funnel hopper. The material conveying path is single. When a large flow of material is crowded in the straight cylindrical material pipe or funnel hopper, it will accumulate at the feeding port, preventing the material from smoothly entering the screen box. Traditional screen boxes do not have multiple feeding ports and feeding paths, so they cannot divert the material and convey it along multiple feeding ports. This is a shortcoming that needs to be improved. When feeding material into the screen box of an existing vibrating screen, there is a problem that the screen box does not have a feeding port device to divert the material and convey it along multiple feeding ports. To address this, this application proposes a feeding port structure for a vibrating screen. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 5 This utility model provides a technical solution: a feed inlet structure for a vibrating screen, including a feeding mechanism installed on the screen box of the vibrating screen, comprising a feed hopper 1 and a guide plate 4 fixed by screws, a fixing plate 6 fixed to the guide plate 4 by screws, a guide pipe 7 penetrating the fixing plate 6, and a diverting block 5 installed between opposing guide plates 4, such as... Figure 1 As shown in the figure, A is the screen box. The feed hopper 1 and the diversion pipe 2 are installed on the screen box A. The feed hopper 1 is fixed to the screen box A with screws. The diversion pipe 2 is inserted into the interior of the screen box A. The guide plate 4 plays a guiding role, allowing the material to fall to the center of the feed hopper 1 under the action of gravity on the inclined surface of the guide plate 4. The diversion block 5 plays a diversion role, causing the material to be diverted and flow into the guide pipe 7 on the fixed plate 6. The diverted material flows down from the guide pipe 7. The diversion pipe 2 is sleeved on the outside of the guide pipe 7 at the top and is connected to the guide pipe 7. There are three guide pipes 7 arranged side by side on the fixed plate 6, and there are also three diversion pipes 2. The three guide pipes 7 and the diversion pipe are connected to each other. 2. The material inside the feed hopper 1 is diverted and conveyed along three discharge paths to avoid congestion and blockage inside the feed hopper 1. The vibrating material distribution assembly includes a vibrating plate 9 whose top end is fixed to the guide plate 4 by screws, a connecting rod 3 fixedly connected to the bottom end of the vibrating plate 9, and a diverting component 8 installed between the bottom ends of the opposing connecting rods 3. The material conveyed by the guide pipe 7 falls on the surface of the diverting component 8, and the material spreads on the conical surface of the diverting component 8, so that the material is in a dispersed state and avoids material agglomeration. By impacting the diverting component 8, the connecting rod 3, the vibrating plate 9 and the guide plate 4 are subjected to vibration force. The guide plate 4 vibrates and the disturbance column 41 on it vibrates slightly, which can disturb the material inside the feed hopper 1 and facilitate the falling of the material.

[0016] In this embodiment, the diverting block 5 has an isosceles triangular three-dimensional structure, and the surface opposite to the diverting block 5 is an inclined plane a. The surface of the guide plate 4 matches the inclined plane a, and the guide plate 4 is tightly attached to the diverting block 5. The guide plate 4 plays the role of diverting the material, causing the material to flow towards the surface of the fixed plate 6.

[0017] In this embodiment, a disturbance column 41 in an inclined state is fixedly connected to the surface of the guide plate 4. The disturbance column 41 also plays a role in diverting the flow. In addition, when the connecting rod 3, the vibrating plate 9 and the guide plate 4 are subjected to vibration force, the guide plate 4 vibrates and the disturbance column 41 on it vibrates slightly, which can disturb the material inside the feed hopper 1 and facilitate the material to fall under the action of gravity.

[0018] In this embodiment, the diversion pipe 2 is a circular pipe with a diameter that gradually narrows from top to bottom. The inner wall of the diversion pipe 2 has a certain inclination angle, which helps to guide the material to slide down quickly along the inner wall of the diversion pipe 2 and guides the flow direction of the material so that the material is concentrated on the surface of the diversion component 8.

[0019] In this embodiment, the bottom end of the vibrating plate 9 is a right-angle structure, and a locking screw 91 for fixing the connecting rod 3 passes through the bottom end of the vibrating plate 9. A locking nut is screwed onto the bottom end of the locking screw 91, and the vibrating plate 9 and the connecting rod 3 are fixed by the locking screw 91.

[0020] In this embodiment, the top and bottom ends of the inclined connecting rod 3 are both horizontally bent. The connecting rod 3 connects the diverter 8 and the vibrating plate 9 into an integral structure. The bottom end of the connecting rod 3 is fixed to the diverter 8 by screws.

[0021] In this embodiment, the diversion component 8 includes a base plate 81, a connecting cylinder 82 welded to the base plate 81, and a diversion cone 83 fixed to the connecting cylinder 82 by screws. The outer surface of the top of the connecting cylinder 82 is a conical curved surface. The centers of the diversion cone 83, the connecting cylinder 82, the base plate 81, and the diversion pipe 2 are on the same vertical axis. There is a height difference between the connecting cylinder 82, the diversion cone 83, and the base plate 81. The material diffuses on the surface of the diversion cone 83, and the diffused material falls on the conical surface of the connecting cylinder 82. The material diffuses again, and the material that diffuses a second time falls on the surface of the base plate 81. Under the action of the height difference, the falling material bounces. After diffusion and bouncing, the material is in a dispersed state.

[0022] Working principle and usage process of this utility model: When the material is conveyed into the screen box A, the feed hopper 1 is installed on the screen box A, and the diversion pipe 2 and the diversion component 8 are inserted into the screen box A. The material is poured into the feed hopper 1. The guide plate 4 plays a guiding role, and the disturbance column 41 initially disperses the material, so that the material slides down the inclined guide plate 4 surface and falls to the center of the feed hopper 1 under the action of gravity. The diverting block 5 serves to divert the material, causing it to flow into the guide tube 7 on the fixed plate 6. The diverted material flows down from the guide tube 7. There are three guide pipes 7 and diversion pipes 2, which divert the material inside the feed hopper 1 and transport it along three discharge paths to avoid the material from being crowded and blocked inside the feed hopper 1. There is a height difference between the connecting cylinder 82, the diversion cone 83, and the bottom plate 81. The material diffuses on the surface of the diversion cone 83, and the diffused material falls on the cone surface of the connecting cylinder 82. The material diffuses again, and the material that diffuses a second time falls on the surface of the bottom plate 81. Under the action of the height difference, the falling material bounces. Through diffusion and bouncing, the material is in a dispersed state. The falling material impacts the diverting component 8, causing the connecting rod 3, the vibrating plate 9, and the guide plate 4 to be subjected to vibration. The guide plate 4 vibrates and the disturbance column 41 on it vibrates slightly, which can disturb the material inside the feed hopper 1 and facilitate the falling of the material. In summary, this application provides a feeding device that diverts material on a screen box and conveys it along multiple feeding ports. The feeding hopper 1 is equipped with three guide pipes 7 and a diversion pipe 2, which diverts the material inside the feeding hopper 1 and conveys it along three discharge paths, avoiding material congestion and blockage inside the feeding hopper 1. The material impacts the diversion component 8, and the vibrating diversion component 8 disperses the material. The guide plate 4 and the disturbance column 41 vibrate slightly, disturbing the material inside the feeding hopper 1, which is conducive to the material falling.

[0023] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
