Description

Technical Field

[0002] Mining is the technology and science of extracting mineral resources from within the earth's crust and on the earth's surface. In a broad sense, mining also includes the extraction of coal and petroleum. The mining industry is an important raw material industry, and stone crushing devices are often used in mining engineering. At the same time, due to different uses of stones, there are also requirements for their diameter sizes. When processing stones, the stones are usually placed in a crushing box, and then the hammers inside the crusher continuously strike the stones to achieve the crushing of the stones.

[0024] 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.

[0025] Please refer to Figures 1-5 , the present invention provides a technical solution for a stone crushing and processing device for mining construction: including a fixed frame 1. Inside the fixed frame 1 and along its side wall from top to bottom, a crushing box 2, a pulverizing box 3, and a rolling box 4 are sequentially installed. And the crushing box 2, the pulverizing box 3, and the rolling box 4 are interconnected. At the same time, the outer side walls of both sides of the crushing box 2, the pulverizing box 3, and the rolling box 4 are fixedly connected to each other through connecting members. An inlet 5 is opened on the outer top of the crushing box 2. Through-type first discharge ports 6 and second discharge ports 7 are respectively opened on the outer side walls of the crushing box 2 and the pulverizing box 3 that are opposite to each other. At the same time, a through-type third discharge port 8 is also opened on the outer bottom of the rolling box 4. Crushing components, pulverizing components, and rolling components for grading and crushing stones are respectively arranged inside the crushing box 2, the pulverizing box 3, and the rolling box 4. The crushing component includes an annular coarse sieve plate 18 fixedly installed at the center position of the inner bottom surface of the crushing box 2. One end of two rotating shafts 9 penetrates the crushing box 2 and extends to the outer side wall of the other side of the crushing box 2. And first gears 19 are fixedly installed on the outer peripheral surfaces of the two rotating shafts. The two groups of first gears 19 are meshed. The inner bottom surface of the crushing box 2 is designed to be inclined, and its inclined end corresponds to the first discharge port 6. Inside the crushing box 2 and on the outer peripheral surfaces of the two rotating shafts 9, rotating rollers 20 are fixedly installed. Crushing arc blocks 21 are fixedly installed on the outer peripheral surfaces of the two rotating rollers 20 at equal intervals. And the multiple crushing arc blocks 21 are designed to be correspondingly crossed with each other. When crushing, first, the stones to be processed are fed into the crushing box 2 along the inlet 5. Then, under the meshing characteristics of the first gears 19, the rotating shafts 9 drive the crushing arc blocks 21 on the rotating rollers 20 to perform corresponding crosswise relative rotation, so as to perform the first crushing treatment on the stones. The larger stones are discharged along the first discharge port 6, while the relatively smaller stones fall into the pulverizing box 3 along the annular coarse sieve plate 18 for subsequent pulverizing treatment, which is beneficial to improving the overall crushing efficiency.

[0026] The crushing component includes an annular chamber 22 and a square chamber 23 respectively opened at the upper and lower ends inside the crushing box 2. Crushing racks 24 arranged at equal intervals are fixedly installed on the inner peripheral side wall of the annular chamber 22. The inner bottom surface of the square chamber 23 is designed to be inclined, and its inclined end corresponds to the second discharge port 7. At the same time, a square sleeve 25 is fixedly installed at the center position of the inner bottom surface of the square chamber 23, and the drive shaft rod 10 passes through the inside of the square sleeve 25.

At the same time, one end of the crankshaft rod 27 passes through the square sleeve 25 and extends into the internal of the subsequent chamber, and a conical annular tooth cone 30 is fixedly installed on the outer peripheral surface. A through-type fine sieve hole 31 is opened on the outer bottom surface of the square sleeve 25 and on the inner bottom surface of the square chamber 23. When crushing, while the drive shaft rod 10 drives the worm 29 to rotate, the worm gear 28 drives the crankshaft rod 27 to rotate in the square sleeve 25, thereby driving the annular tooth cone 30 to rotate. Under the interaction of the crushing racks 24, the stones after preliminary crushing are subjected to secondary crushing treatment. The larger stones are discharged along the second discharge port 7, and the relatively smaller ones fall into the rolling box 4 through the fine sieve holes 31 for rolling treatment. Compared with the crushing box 2, the crushing box 3 can carry out refined treatment on the stones, improve the diversity of stone crushing, and further improve its scope of application.

[0027] The rolling component includes rolling rollers 32 symmetrically arranged inside the rolling box 4. One end of two rotating shaft rods 11 passes through the rolling box 4 and extends to the outer side wall on the other side of the rolling box 4. Second gears 33 are fixedly installed on the outer peripheral surfaces of the two rotating shaft rods 11. The two groups of second gears 33 are meshed. The outer peripheral surfaces of the two rotating shaft rods 11 are fixedly sleeved with the two rolling rollers 32. When rolling, the rolling rollers 32 are driven by the rotating shaft rods 11 to roll the small crushed stones, and roll them into more appropriately sized stones for convenient subsequent reprocessing.

[0028] The connecting piece includes a first connecting block 34, a second connecting block 35 and a third connecting block 36 respectively fixedly installed on the outer side walls on both sides of the crushing box 2, the crushing box 3 and the rolling box 4. The first connecting block 34, the second connecting block 35 and the third connecting block 36 are fixedly connected to each other by bolts. The cooperation of the first connecting block 34, the second connecting block 35, the third connecting block 36 and the bolts can fixedly connect the crushing box 2, the crushing box 3 and the rolling box 4 to each other, and at the same time, it is also convenient for subsequent disassembly, maintenance and replacement.

[0029] The crushing component, the pulverizing component, and the rolling component are rotationally connected to each other through a linkage component. The linkage component includes a rotating shaft rod 9 rotatably connected to both ends of the outer side wall of one side of the crushing box 2, a driving shaft rod 10 rotatably connected to the outer side walls of both sides of the pulverizing box 3, and a rotating shaft rod 11 rotatably connected to both ends of the outer side wall of one side of the rolling box 4. A first pulley 12 is fixedly installed on the outer peripheral surface of one of the two rotating shaft rods 9. Second pulleys 13 and third pulleys 14 are respectively fixedly installed on the outer peripheral surfaces of both ends of the driving shaft rod 10. The first pulley 12 and the second pulley 13 are rotationally connected by a first transmission belt 16. A fourth pulley 15 is fixedly installed on the outer peripheral surface of one of the two rotating shaft rods 11. The third pulley 14 and the fourth pulley 15 are rotationally connected by a second transmission belt 17. A driving motor 26 is fixedly installed on the outer side wall of the pulverizing box 3, and the output end of the driving motor 26 is fixedly connected to the driving shaft rod 10. During linkage, the driving motor 26 is started to drive the driving shaft rod 10 to rotate, so that the second pulley 13 and the third pulley 14 respectively drive the first pulley 12 and the fourth pulley 15 to rotate synchronously through the first transmission belt 16 and the second transmission belt 17, so that the rotating shaft rod 9, the driving shaft rod 10, and the rotating shaft rod 11 can be synchronously linked without adding an additional power device, thus avoiding the repeated waste of resources and realizing the green production principle of energy conservation and emission reduction.

[0030] The working principle of the present utility model is as follows: When in use, the stones to be processed are first fed into the crushing box 2 along the feeding port 5. Immediately afterwards, the driving motor 26 is started to drive the driving shaft rod 10 to rotate, so that the second pulley 13 drives the first pulley 12 synchronously through the first transmission belt 16, and the first gears 19 on the rotating shaft rod 9 mesh with each other, so that the crushing arc blocks 21 on the two rotating rollers 20 perform corresponding crosswise relative rotation to perform the first crushing treatment on the stones. The larger stones are discharged along the first discharge port 6, and the relatively smaller stones fall into the pulverizing box 3 along the annular coarse sieve plate 18.

[0031] At the same time, when the driving shaft rod 10 rotates, it synchronously drives the worm 29 to drive the worm wheel 28 to rotate, so that the worm wheel 28 drives the crank shaft rod 27 to rotate in the square sleeve 25, and then drives the annular tooth cone 30 to rotate. Under the interaction of the crushing rack 24, the stones after preliminary crushing are subjected to secondary fine pulverization treatment. The larger stones are discharged along the second discharge port 7, and the relatively smaller ones fall into the rolling box 4 through the fine sieve holes 31.

[0032] Meanwhile, the fourth pulley 15 is synchronously driven to rotate by the third pulley 14 and the second transmission belt 17, so that the second gears 33 on the rotating shaft rods 11 mesh with each other, enabling the rolling rollers 32 on the two rotating shaft rods 11 to perform rolling treatment on the crushed small stones, rolling them into stones with a more appropriate size, and then discharging the rolled stones through the third discharge port 8 for convenient subsequent reprocessing.

[0033] Through the treatment of the crushing box 2, the pulverizing box 3, and the rolling box 4, stones of different scales can be simultaneously crushed according to different uses, which is convenient and fast.

[0034] Finally, when it is necessary to disassemble, maintain, and replace the crushing box 2, the pulverizing box 3, and the rolling box 4, the bolts can be directly removed from the first connecting block 34, the second connecting block 35, and the third connecting block 36, and then they can be separated from each other.

[0035] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in this field without special instructions and limitations.
