Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ore mining, in particular to an ore mining and screening machine. Background Technique
[0002] When mining ores, a screening machine is needed to classify the ores according to their sizes, which is convenient for subsequent removal of impurities and waste stones. However, most traditional screening machines use belts to convey the ores from the stacking area to the feeding port of the screening machine, that is, the ores are concentrated for feeding from one side or a point of the sieve mesh. Such a feeding method will cause the ores to be unable to be evenly distributed on the sieve mesh, resulting in too much material distribution in some areas of the sieve mesh and too little material distribution in other areas, thereby reducing the screening efficiency.
[0003] Therefore, in order to solve the defect that the centralized feeding of the ore screening machine will reduce the screening efficiency, it is very necessary to propose an ore mining and screening machine. Content of the Utility Model
[0004] The purpose of the utility model is to provide an ore mining and screening machine, which evenly disperses the ores in the cloth hopper through a material distributing plate and then spreads them onto the sieve mesh through a cloth opening, ensuring the even distribution of the ores on the entire sieve mesh, thereby improving the screening efficiency, so as to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] An ore mining and screening machine includes a bottom plate, a threaded rod and a driving shaft movably installed at the upper end of the bottom plate. One end of the threaded rod is fixedly connected with a first bevel gear. One end of the driving shaft is fixedly connected with a first motor, and a second bevel gear meshing with the first bevel gear is arranged on its rod body. A screening hopper is installed on the bottom plate through a spring. A cloth hopper is horizontally arranged at the upper end of the screening hopper. The cloth hopper is threadedly connected with the threaded rod through a sliding seat, and a rotating shaft is movably installed inside it. One end of the rotating shaft is fixedly connected with a second motor, and material distributing plates are annularly arranged on its rod body. A cloth opening is formed at the bottom of the cloth hopper.
[0007] Preferably, the screening hopper is divided into upper and lower two material cavities by a filter screen. A first discharge port is formed on the left side of the upper material cavity, the bottom of the lower material cavity inclines towards the lower right corner to form a slope, and a second discharge port is formed on its right side.
[0008] Preferably, a baffle is slidably connected at the first discharge port.
[0009] Preferably, a vibration motor is installed at the bottom of the screening hopper.
[0010] Preferably, a pushing plate is slidably connected at the cloth opening, and the pushing plate is fixed by a bolt.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] 1. This ore mining and screening machine evenly disperses the ore in the distribution hopper through the distribution plate and spreads it onto the filter screen from the distribution port, ensuring that the ore is evenly covered on the entire screen surface, avoiding the situation where the material is too much distributed in some areas of the screen due to centralized feeding, and too little distributed in other areas, thereby reducing the screening efficiency;
[0013] 2. This ore mining and screening machine can continuously throw up and down ore particles through the periodic vibration generated by the vibration motor, which helps the ore particles to better contact the filter screen, and effectively prevent or reduce the blockage of the filter screen, keeping the filter screen unobstructed.

DETAILED DESCRIPTION
[0019] 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.
[0020] To solve the technical problem of how to evenly distribute the material in the screening machine, please refer to Figures 1-4 , this embodiment provides the following technical solutions:
[0021] An ore mining and screening machine includes a bottom plate 1, a threaded rod 11 and a drive shaft 13 movably installed at the upper end of the bottom plate 1. One end of the threaded rod 11 is fixedly connected to a first bevel gear 12. One end of the drive shaft 13 is fixedly connected to a first motor 15, and a second bevel gear 14 meshing with the first bevel gear 12 is provided on its rod body. A screening hopper 2 is installed on the bottom plate 1 through a spring 25. A feeding hopper 3 is horizontally arranged at the upper end of the screening hopper 2. The feeding hopper 3 is threadedly connected to the threaded rod 11 through a sliding seat 31, and a rotating shaft 33 is movably installed inside it. One end of the rotating shaft 33 is fixedly connected to a second motor 35, and a distributing plate 34 is annularly arranged on its rod body. A feeding port 32 is opened at the bottom of the feeding hopper 3.
[0022] Specifically, start the first motor 15. The motor drives the second bevel gear 14 to rotate through the drive shaft 13. The second bevel gear 14 then drives the first bevel gear 12 meshing with it to rotate. Therefore, the threaded rod 11 will also rotate accordingly. At this time, the feeding hopper 3 is threadedly connected to the threaded rod 11 through the sliding seat 31. Therefore, when the threaded rod 11 rotates, the feeding hopper 3 will move along the axial direction of the threaded rod 11. Inside the feeding hopper 3, the rotating shaft 33 rotates driven by the second motor 35 and drives the distributing plate 34 to rotate. When the ore is conveyed to the feeding hopper 3 through a belt, the distributing plate 34 will disperse the ore, and with the movement of the feeding hopper 3 and the rotation of the distributing plate 34, the ore will be evenly spread onto the screen of the screening hopper 2 through the feeding port 32.
[0023] To solve the technical problem of how the screening machine screens materials, please refer to Figures 2-4 , the following technical solutions are provided in this embodiment:
[0024] A vibration motor 26 is installed at the bottom of the screening hopper 2. The screening hopper 2 is divided into upper and lower two material chambers by a filter screen 22. A first discharge port 23 is opened on the left side of the upper material chamber. A baffle plate 21 is slidably connected at the first discharge port 23. The bottom of the lower material chamber is inclined to form a slope towards the lower right corner, and a second discharge port 24 is opened on its right side.
[0025] Wherein, a pushing plate 321 is slidably connected at the feeding port 32. The pushing plate 321 is fixed by a pin 322. The setting of the pushing plate 321 is to facilitate the collection of the ore intercepted on the filter screen 22.
[0026] Specifically, when the ore is evenly distributed on the filter screen 22, start the vibration motor 26 to generate vibration to assist in screening the ore until the ore particles with small diameters pass through the filter screen 22 and fall into the blanking cavity. At this time, the bottom of the blanking cavity forms a slope, which helps the flow of ore particles, so that the ore particles with small diameters will drain out from the second discharge port 24 along the slope. Then adjust the pushing plate 321 so that the bottom of the pushing plate 321 contacts the filter screen 22, and open the baffle plate 21. Then start the first motor 15 so that the pushing plate 321 can move together with the feeding hopper 3, push the ore remaining on the filter screen 22, and push the ore out from the first discharge port 23 to achieve the screening and collection of the ore.
[0027] Working principle: When this ore mining and screening machine is in use, start the first motor 15. This motor drives the second bevel gear 14 to rotate through the drive shaft 13. The second bevel gear 14 drives the threaded rod 11 to rotate through the first bevel gear 12. Since the feeding hopper 3 is threadedly connected to the threaded rod 11 through the sliding seat 31, the feeding hopper 3 will move along the axial direction of the threaded rod 11. When the ore is conveyed to the feeding hopper 3 through the belt, the distributing plate 34 will disperse the ore and evenly spread it onto the filter screen 22 through the feeding port 32. At this time, start the vibration motor 26 to assist in screening the ore until the screening is completed. The ore particles with small diameters pass through the filter screen 22 and fall into the blanking cavity and drain out from the second discharge port 24 along the slope. Then adjust the pushing plate 321 so that its bottom contacts the filter screen 22, and open the baffle plate 21. Then start the first motor 15 so that the pushing plate 321 can move together with the feeding hopper 3, push the ore remaining on the filter screen 22, and push the ore out from the first discharge port 23 to achieve the screening and collection of the ore.
