Technical Field
[0001] The utility model relates to the technical field of ore crushers, in particular to an ore crusher for mines. Background Technique
[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain utilizable properties. The unit content of the useful components in the ore is called the ore grade. The precious metal ores such as gold and platinum are expressed in grams or tons, and other ores are commonly expressed in percentages. The ore grade is often used to measure the value of the ore. However, the composition of gangue and the amount of harmful impurities in the ore with the same effective components also affect the ore value. In order to facilitate transportation and use, the ore needs to be crushed and decomposed.
[0003] However, when most of the current mine crushers on the market are in use, the crushing effect is limited, and the crushed ore cannot be screened and crushed again, resulting in a large difference in the size of the crushed ore, thus affecting the use. Moreover, a large amount of dust is generated during the ore crushing process, but the existing crushers are not convenient to install equipment for dust reduction treatment. Content of the Utility Model

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0018] Embodiment: As Figures 1-5 shown, the present invention provides an ore crusher for mines, including a screening bin 1. One side of the screening bin 1 is fixedly installed with a first crushing bin 2. The top of the screening bin 1 is fixedly installed with a second crushing bin 3. A driving assembly is arranged on one side of the second crushing bin 3. Two mutually cooperating second crushing rollers 32 are rotatably installed in the middle of the second crushing bin 3. A second gear 33 is fixedly installed on one side of each of the two second crushing rollers 32. The two second gears 33 are meshed and connected with each other. A screening plate 12 is obliquely arranged in the middle of the screening bin 1. Four symmetrically distributed fixing blocks 13 are fixedly installed inside the screening bin 1. Springs 14 are fixedly installed on the tops of the four fixing blocks 13. The bottom corners of the screening plate 12 are fixedly installed on the tops of the springs 14. Two mutually cooperating first crushing rollers 23 are rotatably installed in the lower part of the first crushing bin 2. A first gear 24 is fixedly installed on one side of each of the two first crushing rollers 23. The two first gears 24 are meshed and connected with each other. A first motor 21 is arranged on one side of the first crushing bin 2. One side of one of the first crushing rollers 23 is fixedly installed on the driving end of the first motor 21.
[0019] A feed bin 34 is fixedly installed at the top of the second crushing bin 3. Slots 35 are opened in the middle of both sides of the feed bin 34. Baffles 36 are slidably arranged in the middle of the two slots 35. A dust collector 38 is fixedly installed at the top of the first crushing bin 2. The input end of the dust collector 38 is fixedly installed in the middle of both sides of the feed bin 34.
[0020] The driving assembly includes a second motor 31. The bottom end of the second motor 31 is fixedly installed on one side of the top of the screening bin 1. One end of one of the second crushing rollers 32 is fixedly installed on the driving end of the second motor 31. By setting the second motor 31, one of the second crushing rollers 32 can be driven to rotate. Under the mutual cooperation of the second gears 33, the two second crushing rollers 32 rotate relatively to crush the ore.
[0021] A fixing plate 22 is fixedly installed at the lower part of one side of the first crushing bin 2. The bottom end of the first motor 21 is fixedly installed on the top of the fixing plate 22. By setting the fixing plate 22, the first motor 21 can be installed on the top of the fixing plate 22 to fix the first motor 21.
[0022] On one side of each of the two baffles 36, four evenly distributed bolts 37 are threadedly installed. On one side of the multiple bolts 37, they are threadedly installed in the middle of the feed bin 34. By setting the bolts 37, the baffles 36 are fixed by the bolts 37. By means of the baffles 36, when the ore is being crushed, it can be prevented that crushed stones enter the interior of the dust collector 38 through the trough 35, resulting in damage to the dust collector 38.
[0023] In the middle of the top of each of the four fixing blocks 13, a telescopic rod 15 is fixedly installed. At the four corners of the bottom end of the screening plate 12, they are fixedly installed at the top of the telescopic rods 15. By setting the telescopic rods 15, under the limitation of the telescopic rods 15, the up-and-down movement of the screening plate 12 is made more stable.
[0024] At the bottom end of the first crushing chamber 2 and the screening chamber 1, a discharge bin 4 is fixedly installed. By setting the discharge bin 4, the ore discharged from the first crushing chamber 2 and the screening chamber 1 is discharged through the discharge bin 4.
[0025] In the middle of both sides of the first crushing chamber 2 and the screening chamber 1, support rods 11 are fixedly installed. By setting the support rods 11, the overall device plays a supporting role, facilitating the discharge of the lower discharge bin 4.
[0026] Working principle: During actual use, the ore is put into the interior of the second crushing chamber 3 through the feed bin 34. By starting the second motor 31 to drive one of the second crushing rolls 32 to rotate, that is, driving the second gear 33 to rotate. Through the meshing connection of the two second gears 33, the two second crushing rolls 32 rotate relative to each other, thereby crushing the ore. The crushed ore falls into the interior of the screening chamber 1 and thus reaches the upper part of the screening plate 12. Due to the gravitational force, it impacts the screening plate 12, causing the screening plate 12 to move downward and compress the lower spring 14. Under the reaction force of the spring 14, the screening plate 12 moves up and down, thereby screening the ore that has fallen from the second crushing chamber 3. The qualified ore is discharged through the discharge bin 4 after being screened by the screening plate 12, while the ore with unqualified size and large size slides downward along the inclined screening plate 12 and falls onto the upper part of the first crushing roll 23. By driving the first crushing roll 23 to rotate by the first motor 21, under the meshing connection of the first gear 24, the two first crushing rolls 23 rotate. After the ore is crushed again by the two first crushing rolls 23, the ore is discharged from the middle of the discharge bin 4;
[0027] During the crushing process, a large amount of dust will be generated. The dust moves upward and is discharged through the feed bin 34. By starting the dust collector 38, since the input end of the dust collector 38 is fixedly installed in the middle of the troughs 35 opened on both sides of the feed bin 34, the dust collector 38 sucks away the dust through the troughs 35.
[0028] Obviously, those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
