Technical Field

[0001] This application relates to the field of ultrasonic crushing, and more particularly, to a mineral crushing device based on ultrasonic waves. Background Art

[0002] For a mineral ultrasonic crushing device, it mainly contacts the stone material through an ultrasonic probe. The ultrasonic wave is generated by an acoustic wave generator, that is, the ultrasonic probe.

The main purpose is to break a large piece of stone material into several small pieces of stone material. However, the crushing speed is relatively slow. It may take several seconds to initially generate crushing cracks, which will greatly affect the production speed of crushed stone materials. Summary of the Invention

[0037] More specifically, there are four groups of crushing bits 3, and two of the groups are centrosymmetric about the center of the sealing shell 11 with the other two groups. One group of the crushing bits 3 is connected to the first power component 76. Exactly speaking, the first gears 768 are arranged on each of the crushing bits 3 in this group. There are three crushing bits 3 in this group. The rack 767 meshes with the first gears 768, so that the rack 767 will drive the multiple first gears 768 to rotate simultaneously, and thus the multiple crushing bits 3 will rotate simultaneously. The rotation directions of the multiple crushing bits 3 are the same.

[0038] The driving member 74 includes: a support plate 741, a first driving motor 742, a driving nut 743, a transmission connecting rod 744, a transmission block 745, and a driving lead screw 746. The support plate 741 is fixedly installed on the sealing shell 11, the first driving motor 742 is installed on the support plate 741, the driving lead screw 746 is rotatably connected to the support plate 741 and the support plate 741 is connected to the first driving motor 742, the driving nut 743 is threadedly installed on the driving lead screw 746, the transmission block 745 is fixedly installed on the driving plate 71, one end of the transmission connecting rod 744 is hinged to the transmission block 745, and the other end of the transmission connecting rod 744 is hinged to the driving nut 743. Among them, two driving nuts 743, transmission connecting rods 744, and transmission blocks 745 are provided, and the helix directions of the threads formed on both ends of the driving lead screw 746 are opposite. Thus, the first driving motor 742 drives the driving lead screw 746 to rotate, and the driving lead screw 746 will cause the two driving nuts 743 to approach and move away from each other.

[0039] The refrigerating member 6 includes: a refrigerating unit 61, a first delivery pipe 62, a second delivery pipe 63, and a third delivery pipe 64. The refrigerating unit 61 is fixedly installed on the box body 1, the first delivery pipe 62 is fixedly connected to the refrigerating unit 61, both the second delivery pipe 63 and the third delivery pipe 64 are fixedly communicated with the first delivery pipe 62, the third delivery pipe 64 is communicated with the cooling chamber 15, and the second delivery pipe 63 is communicated with the accommodating chamber 16. The refrigerating unit 61 is used to input cold air into the first delivery pipe 62.

[0040] Working process:

[0041] When in use, the mineral stone is put into the box body 1 from the top of the box body 1. At this time, the electric door 41 closes the material dropping port. Then the mineral stone will fall into the cooling chamber 15. The refrigerating unit 61 will input cold air into the first delivery pipe 62. Then the cold air will enter the second delivery pipe 63 and the third delivery pipe 64. Then the cold air will reach the cooling chamber 15 and the accommodating chamber 16.

[0042] When the cold air reaches the cooling chamber 15, it will cool the mineral stone in the cooling chamber 15, and the mineral stone is in a low-temperature state. Then the electric doors 41 will move away from each other to open the material dropping port. Then the mineral stone will fall into the heating chamber 14. Then the electric doors 41 will close again. Then the hot air blower and the hot air duct will heat the mineral stone in the heating chamber 14. The mineral stone changes from a low-temperature state to a high-temperature environment rapidly. Thus, the mineral stone will become brittle and be more easily broken.

[0043] The first driving motor 742 drives the driving lead screw 746 to rotate. The two driving nuts 743 on the driving lead screw 746 approach each other. The driving nuts 743 push the transmission block 745 to move through the transmission connecting rod 744, so that the transmission block 745 drives the driving plate 71 to approach and move away from the sealing shell 11. First, the driving plate 71 moves closer to the sealing shell 11. The driving plate 71 pushes the first push rod 72 to move. The first push rod 72 drives the mounting plate 73 to move. The two mounting plates 73 approach each other to squeeze the mineral stone between the two mounting plates 73. Then the ultrasonic probe 2 mounted on the mounting plate 73 will contact the mineral stone. The mineral stone is multiple massive stones. The ultrasonic probe 2 will be inserted into the gaps between the mineral stones. The ultrasonic probe 2 performs ultrasonic crushing on the mineral stone, causing cracks to appear on the mineral stone. Over time, the mineral stone will be broken into multiple small stones. Since only the mineral stone in contact with the ultrasonic probe 2 will be ultrasonically broken, after many large mineral stones are broken into small pieces, there will be many small pieces of mineral stone that cannot contact the ultrasonic probe 2, so it is difficult to break all the mineral stones.

[0044] At this time, the crushing drill bit 3 is used to break these mineral stones that cannot contact the ultrasonic probe 2. Specifically, as follows, first, when the two mounting plates 73 approach each other, the ultrasonic probe 2 directly contacts the mineral stone, and then the crushing drill bit 3 will also contact the mineral stone. However, the acting force for the crushing drill bit 3 to move is achieved through the push of the driving plate 71 and the first spring 75. The first spring 75 is elastic, so the crushing drill bit 3 can retreat relative to the mounting plate 73. That is, if the crushing drill bit 3 contacts the mineral stone and the mineral stone is not directly broken by the crushing drill bit 3, then when the two mounting plates 73 approach each other, the crushing drill bit 3 will not be able to move with the mounting plate 73. At this time, the first spring 75 is compressed, so mainly the ultrasonic probe 2 ultrasonically breaks the stone to break it off.

[0045] Then, after the stone is broken off, the stone changes from a large and hard piece to multiple small pieces. The crushing drill bit 3 may contact a small piece of stone or may be between two small pieces of stone. If the crushing drill bit 3 contacts a small piece of stone, the hardness of this small piece of stone will be lower than that of the large stone before. And the more the two mounting plates 73 approach each other, if the crushing drill bit 3 does not move with the mounting plate 73, the compression amount of the first spring 75 will increase, so that the thrust received by the crushing drill bit 3 will increase. Then the crushing drill bit 3 will also rotate, which will increase the effect of the crushing drill bit 3 crushing the small piece of stone to a certain extent.

[0046] If the breaking bit 3 contacts the gap between multiple small pieces of stone, the rotation of the breaking bit 3 will, to a certain extent, agitate or crush the multiple small pieces of stone. Then, if the small pieces of stone are agitated, they can contact the ultrasonic probe 2 for ultrasonic crushing.

[0047] Finally, if the particles of the broken stone meet the requirements, they will pass through the filter screen 5 and reach the discharging chamber 13.

[0048] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
