[0002] In the mining industry, the original ore needs to be crushed to a certain extent after mining in order to be transported. In the crushing process, the crushing of the crushing device is highly random, resulting in large differences in the size of the crushed ore. The small volume of ore produced by crushing does not need to be crushed again, while the larger volume of the original ore needs secondary crushing.

[0003] In the prior art, the crushed ores are transported away in a unified manner and then subjected to a unified secondary crushing. Therefore, ores with a smaller volume are also subjected to a secondary crushing, resulting in a large waste of resources. Utility Model Content

[0004] In view of the technical problem in the prior art that all crushed ores are subjected to secondary crushing, resulting in a waste of resources, the utility model provides an ore classification device, which can classify the crushed ores by volume to achieve the advantage of saving resources.

[0034] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0035] Example:

[0036] See also Figure 1-Figure 3, an ore classification device, comprising a classification channel 1, a sub-screen 2, a push plate 3, a push rod 4 and a driving member 5. Specifically, the top and bottom of the classification channel 1 are both open structures, and the top of one end of the classification channel 1 is a feed inlet, through which the crushed ore is added to the classification channel 1. A sub-screen 2 is arranged at the bottom of the classification channel 1, and the mesh size of the sub-screen 2 gradually increases from the feed inlet end of the classification channel 1 to the discharge port end.

[0037] The push plate 3 is located at one end of the classification channel 1 which is the material inlet, and the plate surface of the push plate 3 is on a vertical plane. The push plate 3 can make reciprocating linear motion along the classification channel 1.

[0038] A push rod 4 is arranged on the back of the push plate 3, one end of the push rod 4 is vertically connected to the push plate 3, and the other end of the push rod 4 is connected to the output end of the driving member 5. The driving member 5 can directly drive the push rod 4 and the push plate 3 to move back and forth in the classification channel 1.

[0039] Preferably, two push rods 4 are arranged in parallel on the push plate 3 , and the driving member 5 includes two cylinders, and the ends of the piston rods of the two cylinders are connected to the two push rods 4 respectively.

[0040] In this embodiment, a sub-screen 2 is arranged at the bottom of the classification channel 1, and then the push plate 3 is driven by the driving member 5 and the push rod 4 to make reciprocating linear motion in the classification channel 1. The crushed ore enters from the feeding port at the top of the classification channel 1, and vibrates the sub-screen 2 under the action of its own gravity, so that small-volume ore passes through the sub-screen 2 and is collected from the bottom of the classification channel 1.

[0041] Under the action of the push plate 3, the ore in the classification channel 1 moves toward one end of the discharge port, and the ore that cannot pass through the classification screen 2 will be discharged from the discharge port to facilitate secondary crushing.

[0042] In this embodiment, the small volume of ore produced after crushing is screened out, thereby reducing the energy consumption during transportation and secondary crushing, thereby achieving the purpose of saving energy.

[0043] In one specific embodiment:

[0044] The classification device also includes a cover plate 6, one end of which is rotatably connected to the two side walls of the classification channel 1, and the connection point is located at the top of the feed port of the classification channel 1, and is at the end of the feed port away from the discharge port, and at the same time, the bottom surface of the cover plate 6 is in sliding contact with the top of the push plate 3.

[0045] In this embodiment, the top of the push plate 3 can be covered by providing the cover plate 6 , thereby preventing the ore entering from the feed port from falling onto the back side of the push plate 3 .

[0046] In another specific embodiment:

[0047] One end of the sub-screen 2 is rotatably connected to one end of the classification channel 1 , and a spring 13 is provided on the other end of the sub-screen 2 . The spring 13 is arranged in the vertical direction and is located below the sub-screen 2 .

[0048] In this embodiment, the ore entering from the feed port falls on the sub-screen 2 and causes the sub-screen 2 to vibrate. By adding a spring 13, the vibration amplitude of the sub-screen 2 can be increased, thereby driving the existing ore on the sub-screen 2 to jump, and the small-sized ore sandwiched between the large-sized ore is shaken off onto the sub-screen 2, thereby enhancing the classification efficiency.

[0049] In another specific embodiment:

[0050] The bottom of one end of the push plate 3 connected to the push rod 4 is vertically connected to a driving plate 7, and the bottom of the driving plate 7 has a plurality of strip grooves, all of which are arranged parallel to each other, and the spacing between all the strip grooves is equal, and the length direction of all the strip grooves is perpendicular to the length direction of the classification channel 1. All the strip grooves make the bottom surface of the driving plate 7 form a wavy bottom surface. The top of the end of the sub-screen 2 close to the spring 13 has a pressure rod 8, and the top of the pressure rod 8 contacts the bottom of the driving plate 7.

[0051] Preferably, two support rods are provided in parallel at the bottom of the sub-screen 2, the two support rods are respectively close to the two sides of the sub-screen 2, and both ends of the pressure rod 8 are L-shaped and respectively connected to the ends of the two support rods.

[0052] In this embodiment, when the cylinder drives the push plate 3 to reciprocate, the drive plate 7 moves therewith. During this process, the arc grooves on the top surface of the drive plate 7 contact the top of the pressure rod 8 one by one, so that the pressure rod 8 vibrates up and down under the action of the spring 13, thereby driving the vibration of the sub-screen 2 through the support rod.

[0053] In another specific embodiment:

[0054] The classification device also includes two baffles 9, wherein the two baffles 9 are symmetrically arranged and there is a distance between the two baffles 9, the distance forming the above-mentioned classification channel 1, and the tops of the two baffles 9 are respectively extended obliquely toward the middle to prevent the ore in the classification channel 1 from jumping out.

[0055] A limiting plate 10 is respectively provided at the bottom of the two baffles 9, and the end face of the limiting plate 10 is an L-shaped structure, and the two sides of the sub-screen 2 are respectively located under the two limiting plates 10. By setting the limiting plates 10, the width of the sub-screen 2 is made greater than the width of the classification channel 1, thereby preventing the ore from damaging the edge of the sub-screen 2.

[0056] Preferably, an inclined guide plate 11 is provided at the bottom of the classification channel 1, and a plurality of partitions 12 are provided on the guide plate 11. The length direction of the partition 12 is perpendicular to the length direction of the classification channel 1. By providing the guide plate 11, the small-sized ores after screening are guided to a designated position for easy collection. By providing a plurality of partitions 12, ores of different sizes can be classified.

[0057] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
