[0002] Graphite is one of the crystalline minerals of carbon element. It has excellent properties such as lubricity, chemical stability, high temperature resistance, electrical conductivity, special thermal conductivity, plasticity, and coating properties. Its application field is very wide. With the rise of new energy and new material industries, graphite products, especially downstream deep-processed products, have attracted more and more attention. It is gradually becoming an irreplaceable important material in the fields of national defense, aerospace, new materials, etc. In the process of mining, graphite is often large in size and needs to be crushed first. The crushed graphite falls through the feeding funnel.

[0003] Although there are many kinds of feeding funnels at present, there are still some problems. For example, after the graphite is crushed, it needs to be screened by a screening device, and the graphite that does not meet the standards needs to be crushed again. However, most of the current feeding funnels only have the function of transmitting and guiding the material, and cannot perform preliminary screening of the graphite passing through the funnel, which increases the workload and working time of the screening device, resulting in low graphite production efficiency. Therefore, how to improve the production efficiency of graphite has become an urgent problem to be solved. Utility Model Content

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model embodiment provides a feeding funnel for graphite ore crushing, such as Figure 1-4 As shown, it comprises: a protection box 1, a feed hopper 2, a lower hopper 3 and a screening mechanism 6, wherein the feed hopper 2 is arranged at the top of the protection box 1, the lower hopper 3 is arranged at the bottom of the protection box 1, and the screening mechanism 6 is arranged in the internal cavity of the protection box 1;

[0023] The screening mechanism 6 includes a screening unit and a linkage unit;

[0024] The screening unit includes a screening plate 601, a screen 602 and a roller 603. A guide rail 5 is tilted and fixed in the inner cavity of the protective box 1. The roller 603 is rotatably connected to the bottom of the screening plate 601 and is symmetrically arranged frontward, backward, leftward and rightward. The roller 603 partially abuts on the guide rail 5, and the screen 602 is arranged in the screening plate 601.

[0025] The linkage unit includes a transmission rod 604, a push-pull rod 605 and a driven disc 606. A bracket 4 is horizontally fixed to one side of the interior of the protection box 1. The transmission rod 604 is rotatably connected to the bracket 4. The driven disc 606 is fixed to one end of the push-pull rod 605. A disc is provided at the other end of the push-pull rod 605. Both ends of the push-pull rod 605 are rotatably connected to the edge of the disc and the screening disc 601 respectively.

[0026] A servo motor 609 is fixed to the outer wall of the protection box 1 , and a driving disk 608 is fixed to the output shaft of the servo motor 609 . The driving disk 608 is located above the driven disk 606 , and a belt 607 is provided between the driven disk 606 and the driving disk 608 .

[0027] It should be noted that since most of the existing discharge funnels only have the function of transmitting and guiding materials, they are unable to perform preliminary screening of the graphite passing through the funnel, which increases the workload and working time of the screening device, resulting in low graphite production efficiency. In order to solve this problem, a screening mechanism 6 is provided in the present scheme, and the graphite passing through the discharge funnel is preliminarily screened by the screen 602 provided in the screening plate 601, thereby reducing the workload of the external screening equipment and effectively improving the graphite production efficiency.

[0028] Specifically, in this embodiment, this scheme mainly includes a screening unit and a linkage unit, and the screening disk 601 in the screening unit is used to block and support the graphite, and the screen 602 is used to screen the graphite. During screening, the rotation of the transmission rod 604 in the linkage unit drives one end of the push-pull rod 605 to rotate eccentrically, so that the other end of the push-pull rod 605 can drive the screening disk 601 to reciprocate, thereby realizing the screening operation of the graphite and avoiding its accumulation and blockage, thereby greatly improving the screening efficiency. When the screening mechanism 6 is screening the graphite, the servo motor 609 drives the active disk 608 to rotate synchronously, and the belt 607 enables the driven disk 606 to rotate synchronously, so that the transmission rod 604 connected to the driven disk 606 can rotate, and the transmission rod 604 drives one end of the push-pull rod 605 to rotate eccentrically, so that the other end of the push-pull rod 605 can drive the screening disk 601 to reciprocate, thereby realizing the screening operation of the graphite.

[0029] In a further preferred embodiment of the present invention, Figure 1-4 As shown, at least three screening discs 601 are provided, and two adjacent screening discs 601 are fixed by support rods, and the meshes of the screens 602 on the screening discs 601 decrease in size from top to bottom.

[0030] In this embodiment, when the screening mechanism 6 is screening graphite, multiple sets of screening discs 601 and screens 602 are provided to achieve a multi-stage screening effect on the graphite, thereby further improving the screening efficiency.

[0031] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a discharge slot is provided at one end of the screening disc 601, and the discharge slots of two adjacent screening discs 601 are staggered with each other.

[0032] In this embodiment, the graphite in the upper and lower screening discs 601 can be staggered and discharged through the staggered discharging notches to avoid confusion.
