[0002] Concentrate screening is used to remove iron blocks from ore materials to achieve concentrate screening.

[0003] At present, the concentrate screening is often carried out by using a conveyor belt composed of magnetic rollers, and the ore material is poured onto the conveyor belt with a hopper, so that the magnetic rollers can attract the iron blocks to separate the concentrate from impurities such as iron blocks.

[0004] However, in the actual processing process, in order to avoid clogging of ore materials in the hopper, the hopper is usually large. At this time, the ore materials are poured from any position on the top of the hopper, which makes the position on the conveyor belt too concentrated. Not only is the ore material piled too thick, which affects the screening of the magnetic roller, but also the area on the conveyor belt is not fully utilized, resulting in a significant reduction in screening efficiency. Therefore, a uniform distribution structure for concentrate screening is proposed. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-5 As shown, the utility model provides a technical solution of a uniform distribution structure applied to concentrate screening:

[0023] A uniform material distribution structure used for concentrate screening comprises a hopper 1, a side wall of the hopper 1 is provided with an inclined slot 101, the hopper 1 is slidably connected with a material guide inclined plate 2 at the inclined slot 101, a top surface of the material guide inclined plate 2 is provided with a plurality of notches 201, an upper top end of the material guide inclined plate 2 is fixedly connected with an extension plate 3, an end of the extension plate 3 away from the material guide inclined plate 2 is fixedly connected with a connecting plate 301, a reciprocating motion component is provided on the side of the outer side wall of the hopper 1 facing the connecting plate 301, which is used to connect with the connecting plate 301 and drive the extension plate 3 to reciprocate, wherein the reciprocating motion component is configured as a cylinder 6, and an output end of the cylinder 6 is fixedly connected to the connecting plate 301.

[0024] Through the setting and cooperation of the inclined slot 101, the guide inclined plate 2, the recess 201, etc., the guide inclined plate 2 is utilized to slide back and forth on the inclined slot 101, and the material is successfully scattered evenly on the conveyor belt below the hopper 1, which is convenient for further screening. At the same time, the recess 201 can be utilized to accumulate materials, so that the wear intensity of hard and sharp materials on the guide inclined plate 2 is reduced, which greatly improves the service life of the structure. The structural setting is simple and efficient, the operation is automated, and it is durable and suitable for promotion and use.

[0025] A material stripping mechanism is arranged inside the recess 201, and the material stripping mechanism includes a through opening 203 opened on the inner bottom surface of the recess 201, a material guide inclined plate 2 is located at the top of the recess 201 and is fixedly connected to a limiting ring block 202, a support plate 4 is arranged inside the recess 201, and a bottom arc block 401 is fixedly connected to the bottom surface of the support plate 4, wherein it should be supplemented that the side of the bottom arc block 401 facing the inclined groove 101 is arranged as an arc surface, and a plurality of recesses 201 are arranged at equal distances in the horizontal and vertical directions on the top surface of the material guide inclined plate 2, so that the top surface of the material guide inclined plate 2 is evenly and comprehensively protected.

[0026] The setting of the material removal mechanism utilizes the contact between the bottom arc block 401 and the bottom surface of the inclined groove 101, thereby lifting the support plate 4, successfully realizing the convenient discharge of the material accumulated in the recess 201, greatly improving the ease of use of the structure, and no manual cleaning is required. The structural design is simple and efficient, and the operation is automated, and it has a broad application prospect.

[0027] Among them, it needs to be supplemented that the bottom arc block 401 passes through the through-opening 203 and is slidably connected to its inner wall, the limiting ring block 202 limits the support plate 4 in the recess 201, and the two side walls of the material guide inclined plate 2 located in the same sliding direction as the material guide inclined plate 2 are provided with sliding grooves 5, and the inner side wall of the hopper 1 is fixedly connected to the corresponding part of the sliding groove 5 with a limiting strip 102, and the limiting strip 102 extends into the interior of the sliding groove 5. Among them, it needs to be supplemented that the setting of the limiting strip 102 and the sliding groove 5 makes the sliding of the material guide inclined plate 2 on the inclined groove opening 101 more stable.

[0028] Working principle: During use of this structure, the cylinder 6 is started to control the output end of the cylinder 6 to move back and forth slowly. Since the output end of the cylinder 6 is fixedly connected to the connecting plate 301, the connecting plate 301 follows the slow reciprocating movement, and then drives the guide inclined plate 2 to move back and forth slowly on the inclined slot 101 through the extension plate 3. The material to be screened falls from the top of the hopper 1 near the inclined slot 101, and falls into the top of the guide inclined plate 2. It will be filled into the recess 201 first, and then slide down along the top surface of the guide inclined plate 2, and finally fall onto the conveyor belt below the hopper 1 to perform the next step of screening. It should be noted that the conveyor belt is arranged below the hopper 1 in the prior art, which will not be elaborated here.

[0029] The working process of the present device is now explained from the perspective of the guide inclined plate 2 sliding downward from the inclined slot 101. When the cylinder 6 controls its output end to move inward, the connecting plate 301 drives the extension plate 3 to move in the direction close to the hopper 1, and then the guide inclined plate 2 moves from the inclined slot 101 to the side of the hopper 1 opposite the inclined slot 101. This is to evenly sprinkle the material to be screened on the conveyor belt below the hopper 1, avoiding the accumulation of materials caused by the material falling directly from the hopper 1 onto the conveyor belt, which is not conducive to further screening. In this process, the material will be filled into the recess 201 first, so that the material that falls on the guide inclined plate 2 later will first fall on the material accumulated in the recess 201. Since the material is sharp and hard, it will accelerate the wear of the guide inclined plate 2. Through the setting of the recess 201, the falling material can be blocked by the small amount of material accumulated in the recess 201, further improving the service life of the guide inclined plate 2, making the applicability of the present structure stronger.

[0030] The working process of the material removal mechanism is now explained from the perspective of the material guide inclined plate 2 sliding upward from the inclined slot 101. When the cylinder 6 controls its output end to move outward, the connecting plate 301 drives the extension plate 3 to move away from the hopper 1, and then the material guide inclined plate 2 moves from the side of the hopper 1 opposite the inclined slot 101 toward the inclined slot 101, and the bottom arc surface of the bottom arc block 401 will contact the lower edge of the inclined slot 101, so that the bottom arc block 401 is lifted upward, thereby lifting the support plate 4 upward, thereby discharging the accumulated material in the recess 201 out of the recess 201, and the discharged material will fall along the top surface of the material guide inclined plate 2 onto the conveyor belt below the hopper 1.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
