Technical Field

[0001] The utility model relates to the technical field of ore processing, in particular to an ore mining and conveying device. Background Art

[0002] In the process of processing and conveying gold ore, since the naturally produced ore is large in volume, it is usually crushed first, and then the crushed ore of different sizes is screened. Most of the conveying devices in the prior art screen the crushed ore by setting sieve plates with different apertures, but since the crushed ore is in a static state after falling onto the sieve plate, it is easy to block some of the sieve holes on the sieve plate, thereby affecting the subsequent screening effect of the crushed ore. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides a conveying device for ore mining and selection, which has the advantage of keeping the crushed ore in a moving state on the screen plate to avoid blocking the sieve holes and ensure the screening effect. It solves the problem that most of the conveying devices in the prior art screen the crushed ore by setting sieve plates with different apertures, but the crushed ore is in a stationary state after falling onto the screen plate, which is easy to block some of the sieve holes on the screen, thereby affecting the subsequent screening effect of the crushed ore.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A conveying device for ore mining and selection comprises a conveying mechanism for conveying gold ore, one end of the conveying mechanism is provided with a crushing mechanism for crushing and processing the gold ore, the bottom of the crushing mechanism is provided with a screening mechanism for movably screening the crushed ore, the screening mechanism comprises a fixed shell, the side wall of the fixed shell is fixedly connected with a receiving plate, the bottom wall of the fixed shell is respectively fixedly connected with a screen plate a and a screen plate b, three square holes are opened on one side of the fixed shell, side cover plates a, side cover plates b and side cover plates c are respectively movably installed in the three square holes, an iron bar is fixedly connected to the bottom of one side of the fixed shell, a magnetic strip is fixedly connected to the bottom of one side of the side cover plates a, side cover plates b and side cover plates c, and a small cylinder is installed on the bottom wall of the fixed shell.

[0006] Preferably, a sliding hole a and a sliding hole b are respectively opened on the receiving plate, the movable end of the small cylinder is connected to the bottom of the receiving plate, and the sieve plate a and the sieve plate b can slide in the sliding hole a and the sliding hole b respectively.

[0007] Preferably, the crushing mechanism includes a feeding shell, the bottom of which is fixedly connected to a connecting shell, a plurality of crushing wheels are rotatably connected in the connecting shell, one side of the connecting shell is rotatably connected to a gear a and two gears b, the crushing wheel located at the center is connected to gear a, the crushing wheels located on both sides are connected to two gears b, and a crushing motor for driving the crushing wheel at the center is installed on one side of the connecting shell.

[0008] Preferably, the transmission mechanism comprises two side plates connected to one side of the feed shell, and a conveyor belt is installed between the two side plates.

[0009] Preferably, the aperture of the sieve plate a is larger than the aperture of the sieve plate b, and the receiving plate is provided with a plurality of micropores for filtering debris and impurities.

[0010] Preferably, the receiving plate and the bottom surface of the fixed shell are both at an angle of 30° with the horizontal plane, and a plurality of support columns are fixedly connected to the bottom of the fixed shell.

[0011] By means of the above technical solution, the utility model provides a conveying device for ore mining and selection, which has at least the following beneficial effects:

[0012] 1. The utility model sets a screening mechanism so that the device can simply screen the crushed ores of different sizes after crushing. Since there is an angle of 30° between the receiving plate and the horizontal plane, the crushed ores on the receiving plate will slide to one side under the action of gravity, so that the crushed ores of different sizes are separated into different areas by the screen plate a and the screen plate b. At the same time, the small cylinder drives the receiving plate to move, so that the crushed ores in different areas on the receiving plate move, avoiding blocking the sieve holes of the screen plate a and the screen plate b, thereby ensuring the screening effect of the device on the crushed ores.

[0013] 2. The utility model is provided with micropores on the receiving plate, so that when the device is screening the crushed ore, the crushed slag and impurities in the crushed ore can be collected and processed through the receiving plate. At the same time, since the mass and volume of the crushed slag and impurities are small, when the mobile phone paper is fixed between the bottom wall of the shell and the receiving plate, it will not affect the operation of the small cylinder, so that the device can further collect and process the impurities and crushed slag in a simple manner during the screening process of the crushed ore, thereby improving the mining and selection quality of the gold ore by the device.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0023] In the prior art, when conveying ore, it is mostly necessary to classify and convey the crushed ores of different sizes after crushing. Workers screen the crushed ores by setting sieve plates with different apertures. However, since the crushed ore is in a stationary state after falling onto the sieve plate, it is easy to block some of the sieve holes on the sieve plate, thereby affecting the subsequent screening effect of the crushed ore. The following describes an ore mining and conveying device provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] In order to ensure the screening effect of the device on crushed ores of different sizes, combined with Figure 1-Figure 5 As shown, a conveying device for ore mining is proposed, in which a conveying mechanism 1 is provided for conveying gold ore, a crushing mechanism 2 is provided at one end of the conveying mechanism 1, and the gold ore is crushed by the crushing mechanism 2. A screening mechanism 3 is provided at the bottom of the crushing mechanism 2, and crushed ores of different sizes are mobile screened by the screening mechanism 3, so as to facilitate subsequent classification and conveying.

[0026] In order to avoid the crushed ore from blocking the brush hole, a screening mechanism 3 is proposed. A fixed shell 301 is installed. The side wall of the fixed shell 301 is fixedly connected with a receiving plate 302. The bottom wall of the fixed shell 301 is respectively fixedly connected with a sieve plate a303 and a sieve plate b304. Three square holes are opened on one side of the fixed shell 301. Side cover plates a305, b306 and c307 are movably installed in the three square holes. The side bottom is fixedly connected with an iron bar 308, the side cover a305 and the side cover b306 as well as the side cover c307 are fixedly connected with a magnetic strip 309 at the bottom, a small cylinder 310 is installed on the bottom wall of the fixed shell 301, a sliding hole a and a sliding hole b are respectively opened on the receiving plate 302, the movable end of the small cylinder 310 is connected to the bottom of the receiving plate 302, the sieve plate a303 and the sieve plate b304 can slide in the sliding hole a and the sliding hole b respectively, the receiving plate 302 and the fixed shell The bottom surface of 301 is at an angle of 30° with the horizontal plane. The aperture of sieve plate a303 is larger than that of sieve plate b304. The positions of sieve plates a303 and b304 are nearly fixed by fixing the housing 301. The crushed ores of corresponding sizes in different square hole areas are stored by side cover plates a305, b306 and c307. The side cover plates a305, b306 and c307 are closed by iron bars 308 and magnetic bars 309. The receiving plate 302 is fixed together. Since the angle between the receiving plate 302 and the horizontal plane is 30°, the crushed ore will slide to one side of the device under the action of gravity. By controlling the small cylinder 310, the receiving plate 302 slides on the screen plates a303 and b304 through the sliding holes a and b. At this time, the crushed ore located in different areas of the receiving plate 302 also moves up and down, avoiding the sieve holes of the screen plates a303 and b304 being blocked by the crushed ore, thereby ensuring the screening effect of the device on the crushed ore.

[0027] In order to conveniently transport the mined gold ore, a crushing mechanism 2 is proposed, which comprises a feeding shell 201, a connecting shell 202 being fixedly connected to the bottom of the feeding shell 201, a plurality of crushing wheels 203 being rotatably connected in the connecting shell 202, a gear a204 and two gears b205 being rotatably connected to one side of the connecting shell 202, a crushing wheel 203 located at the center being connected to the gear a204, and crushing wheels 203 located at both sides being connected to two gears b205 respectively, a crushing motor for driving the crushing wheel 203 at the center being installed on one side of the connecting shell 202, the gold ore transported by the conveyor belt 102 being transferred through the feeding shell 201, the crushing wheel 203 at the center of the crushing motor being rotated, so that the crushing wheel 203 at the center drives the gear a204 to rotate, so that the gear a204 drives the two gears b205 to mesh and rotate, so that the two gears b205 respectively drive the crushing wheels 203 located at both sides to rotate, thereby ensuring the crushing effect of the device on the gold ore.

[0028] Embodiment 2:

[0029] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem that most of the conveying devices in the prior art screen the crushed ore by setting sieve plates with different apertures, but because the crushed ore is in a stationary state after falling onto the sieve plate, it is easy to block some of the sieve holes on the sieve plate, thereby affecting the subsequent screening effect of the crushed ore. However, in the process of screening the crushed ore, slag and impurities also enter the device together with the gold ore. If they are not simply collected, the crushed ore in different areas will contain more slag and impurities, thereby affecting the collection quality of the crushed ore.

[0030] In order to collect and process the impurities and slag in the crushed ore group, combined with Figure 1 and Figure 3 as well as Figure 5 As shown, a plurality of micropores for filtering debris and impurities are provided on the receiving plate 302. Since the volume of the debris and impurities is mostly smaller than that of the crushed ore, the receiving plate 302 can filter the debris and impurities to a certain extent during the movement, so that the debris and impurities are collected on the bottom wall of the fixed shell 301. When the staff discharges the crushed ore in different areas, the debris and impurities collected by the mobile phone can also be cleaned up, thereby further improving the mining quality of the gold ore by the device.

[0031] In order to facilitate the transportation of the raw gold ore, a transmission mechanism 1 is proposed, in which side panels 101 are respectively connected to two sides of the feed shell 201, a conveyor belt 102 is installed between the two side panels 101, and a plurality of support columns are fixedly connected to the bottom of the fixed shell 301. The conveyor belt 102 is installed and fixed by the two side panels 101, and the whole device is supported by the support columns, thereby ensuring that the device can work stably.

[0032] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0033] 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.
