[0038] The present utility model will be further described in conjunction with the following embodiments.

[0039] Embodiment 1.

[0040] As Figure 1 shown, a magnesia-chrome sand classification ore dressing equipment includes an ore dressing machine housing 1, a feed channel 2 is installed at the top of the ore dressing machine housing 1, a driving motor 3 is installed outside the ore dressing machine housing 1, the output shaft of the driving motor 3 is inserted into the ore dressing machine housing 1 and fixedly connected to the central shaft 4, the central shaft 4 is rotatably connected to one side of the feed channel 2, a crushing mechanism 5 is installed in the feed channel 2, and a vibration mechanism 6 is installed inside the ore dressing machine housing 1;

[0041] The material enters the ore dressing machine housing 1 through the feeding channel 2, and is first crushed by the crushing mechanism 5 to prevent the material from being too large and inconvenient for screening. Then it falls onto the vibrating mechanism 6 to screen and select the qualified material.

[0042] As Figure 1 shown, the vibrating mechanism 6 includes a vibrating screw 61 and a rotating cam 62. The rotating cam 62 is installed on the central shaft 4. The vibrating screw 61 is installed with a vibrating screen A 63, a vibrating screen B 64 and a vibrating bottom plate 65 from top to bottom.

[0043] Above the vibrating screen A 63, the vibrating screen B 64 and the vibrating bottom plate 65, there are all push scraping plates 66 installed. The push scraping plates 66 are threadedly connected to the vibrating screw 61. A return spring 67 is connected between the bottom of the vibrating screw 61 and the ore dressing machine housing 1.

[0044] The drive motor 3 drives the central shaft 4 to make the rotating cam 62 rotate. When the rotating cam 62 rotates downward, it applies a force to the vibrating screw 61, pressing down the vibrating screw 61. The vibrating screw 61 compresses the return spring 67. When the rotating cam 62 rotates upward, the return spring 67 rebounds to push the vibrating screw 61 back to its original position. In this way, it circulates repeatedly to achieve the effect of vibrating screening.

[0045] As Figure 3 shown, the crushing mechanism 5 includes a driving gear 51, a first driven gear 52 and a second driven gear 53. The driving gear 51 is fixedly installed on the central shaft 4. The driving gear 51 meshes with the first driven gear 52. The first driven gear 52 meshes with the second driven gear 53. Both the first driven gear 52 and the second driven gear 53 are fixedly connected to the driven rotating shafts 54. Each driven rotating shaft 54 passes through one side of the feeding channel 2 and is rotatably connected to the other side of the feeding channel 2. A crushing roller 55 is installed on each driven rotating shaft 54.

[0046] The drive motor 3 drives the driving gear 51 to rotate, driving the first driven gear 52 and the second driven gear 53 to rotate towards each other, so that the crushing rollers 55 on the two driven rotating shafts 54 rotate towards each other with the first driven gear 52 and the second driven gear 53 to crush the added material.

[0047] As Figure 1 、 2 shown, three discharge ports 7 are provided on the side of the ore dressing machine housing 1. Above the three discharge ports 7, an adjusting pin seat 8 is installed. A limit pin 9 is slidably connected to the side of the adjusting pin seat 8. An adjusting baffle 10 is inserted into the adjusting pin seat 8. The limit pin 9 passes through the adjusting baffle 10.

[0048] The number of the discharge ports 7 is set to be the same as the number of the screen layers and the vibrating bottom plate 65. By pulling out the limit pin 9 to change the position of the adjusting baffle 10, the size of the discharge port 7 is changed, thus adjusting the discharge speed.

[0049] As shown Figure 1 in the figure, a compression spring 11 is installed between the adjusting baffle 10 and the inside of the adjusting pin seat 8. Three discharge holes 12 of the same size as the discharge port 7 are provided on the adjusting baffle 10, and the distance values between the three discharge holes 12 are equal to the distance values between the three discharge ports 7.

[0050] As shown Figure 1 in the figure, a positioning support seat 13 is installed at the top of the ore dressing machine housing 1. The central shaft 4 passes through the positioning support seat 13, and the central shaft 4 is rotatably connected to the positioning support seat 13 through a bearing. Four limiting holes 14 are evenly provided on the adjusting pin seat 8, and a frustum end 15 is integrally formed at the top end of the vibrating screw 61.

[0051] It should be noted that in this embodiment, the vibrating screen A 63, the vibrating screen B 64 and the vibrating bottom plate 65 are provided, but actually it is not limited to two layers of screens. Sieve layers can be added according to needs, and the number of the discharge holes 12 and the discharge ports 7 can be adjusted correspondingly.

[0052] In the present utility model, materials are added through the feed channel 2 installed at the top of the ore dressing machine housing 1. A driving motor 3 is installed on the outer side of the ore dressing machine housing 1. The output shaft of the driving motor 3 is inserted into the ore dressing machine housing 1 and fixedly connected to the central shaft 4. A crushing mechanism 5 is installed in the feed channel 2 to extrude and crush the added materials. A vibrating mechanism 6 is installed inside the ore dressing machine housing 1. The materials fall into the vibrating mechanism 6. The driving motor 3 drives the central shaft 4, so that the rotating cam 62 applies a force to the vibrating screw 61, thereby driving the vibrating screen A 63, the vibrating screen B 64 and the vibrating bottom plate 65 to vibrate together. By setting multiple layers of screens, the screening efficiency is improved. At the same time, the pushing scraper 66 moves and rotates along with the vibrating screw 61 to prevent the screen from being blocked.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit the protection scope of the present utility model. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present utility model.
