[0002] At present, the ore crushing devices used in ore crushing experiments often introduce additional errors into the experiments during operation, affecting the accuracy of the experiments. For example, when conducting a drop hammer impact test on the same type of ore, some ores can be crushed when the drop hammer falls from a lower position, while some ores require the drop hammer to fall from a higher position to be crushed. This results in a large data discreteness of the experimental results, and it is impossible to accurately determine the load and other data required for ore crushing. At the same time, the existing ore crushing devices have a complex structure, a large size, a large amount of ore crushed at one time, and high production and use costs. They cannot meet the experimental scenarios with limited space and cost, and a small amount of ore crushed at one time. In addition, the existing ore crushing devices are prone to ore fragments splashing during the crushing process, resulting in the loss of some ore fragments, making it difficult to collect all the crushed ore fragments, and the subsequent screening of the ore fragments is highly dependent on manual labor, which results in low experimental accuracy and efficiency. Therefore, the existing ore crushing devices are not suitable for ore crushing experiments. Summary of the Invention

[0018] The present invention is described in detail below with reference to the embodiments, but the present invention is not limited to these embodiments.

[0019] The embodiment of the present invention provides an ore crushing device for ore crushing experiments, such as Figures 1 to 3 As shown, the device includes: frame; The fixed plate 3 is fixedly arranged on the frame and has a first crushing surface; The movable plate body 2 is slidably arranged on the frame and has a second crushing surface; the first crushing surface and the second crushing surface are arranged opposite to each other, forming an ore crushing area therebetween; the bottom end distance between the first crushing surface and the second crushing surface is smaller than the top end distance; A driving assembly connected to the movable plate body 2, used to drive the movable plate body 2 to slide horizontally back and forth on the frame so that the second crushing surface approaches or moves away from the first crushing surface; The screening assembly is arranged on the frame and located below the ore crushing area, and is used to screen the ore fragments falling from the ore crushing area according to the preset particle size.

[0020] The operating principle of the device is as follows: ore 5 is poured into the upper opening of the ore crushing zone, i.e., the top space between the fixed plate 3 and the movable plate 2, and then the drive assembly is started, which drives the movable plate 2 to perform horizontal reciprocating motion. When the movable plate 2 slides horizontally toward the fixed plate 3, the second crushing surface approaches the first crushing surface, and the ore 5 in the ore crushing zone is compressed and crushed to form ore fragments; when the movable plate 2 slides horizontally toward the fixed plate 3, the second crushing surface moves away from the first crushing surface, and the ore fragments fall from the lower opening of the ore crushing zone into the screening assembly, and the ore fragments are screened and collected under the vibration of the drive assembly. Since the working power of the drive assembly is easy to quantify and determine, and the ore crushing load can be accurately and efficiently calculated based on the working power of the drive assembly, this device can reduce experimental errors and improve the accuracy and reliability of experimental data compared to existing ore crushing devices.

[0021] This embodiment does not limit the specific structure of the frame, as long as it can meet the respective position settings and function realizations of the fixed plate body 3, the movable tooth plate, the drive assembly and the screening assembly. This embodiment uses a frame of one structure as an example for explanation.

[0022] In this embodiment, the rack may include: A plurality of support rods 6 are arranged on the ground, and the screening assembly is arranged between the plurality of support rods 6 and connected to the plurality of support rods 6 .

[0023] The frame 15 is arranged at the top ends of the plurality of support rods 6 ; the fixed plate body 3 , the movable plate body 2 and the movable plate body 2 are all arranged on the frame 15 .

[0024] Specifically, a plurality of rollers 11 are respectively provided on two opposite sides of the movable plate body 2 ; slide grooves 12 are provided at positions corresponding to the rollers 11 on the frame; and the rollers 11 can slide horizontally in the corresponding slide grooves 12 .

[0025] The present embodiment does not limit the specific number of rollers 11 and chute 12, as long as it can ensure that the movable plate body 2 can slide back and forth horizontally on the frame. Among them, the roller 11 can adopt a low-friction roller 11 to reduce the friction between the roller 11 and the chute 12.

[0026] In this embodiment, rollers 11 are respectively provided at the top, bottom and middle of the side of the movable plate body 2; correspondingly, slide grooves 12 are respectively provided at the top, bottom and middle of the side of the frame 15; the rollers 11 and the slide grooves 12 correspond to each other and match one by one, and together guide and limit the operation of the movable plate body 2.

[0027] Specifically, the fixed plate body 3 and the movable plate body 2 can be made of high-strength and high-hardness materials so that they can crush ores 5 of different strengths.

[0028] Specifically, the first crushing surface and / or the second crushing surface can be a plane, a tooth surface or other surface structures that can exert an extrusion, splitting, grinding or the like effect on the ore 5 so as to crush the ore 5 .

[0029] Specifically, when the first crushing surface and / or the second crushing surface is a tooth surface, this embodiment does not limit the tooth density and tooth size specifications of the tooth surface. In practice, different tooth densities and tooth sizes can be flexibly selected according to different crushing conditions.

[0030] Specifically, the drive assembly may include: The vibration device 1 is arranged on the frame and is located on the side of the movable plate body 2 away from the second crushing surface; The vibration rod 8 is connected to the movable part of the vibration device 1 at one end and to the movable plate body 2 at the other end. It can reciprocate in the horizontal direction under the drive of the vibration device 1 to drive the movable plate body 2 to slide back and forth horizontally.

[0031] On the one hand, the vibration equipment 1 can drive the movable plate 2 to perform horizontal reciprocating motion through the vibration rod 8 to achieve the crushing of the ore 5. On the other hand, it can transmit its own vibration to the screening component through the frame. The screening component realizes the graded screening and collection of the ore fragments through vibration, thereby achieving the purpose of automatically crushing the ore and automatically screening the ore fragments.

[0032] Specifically, the vibration device 1 may be an impact hammer, and the impact hammer may be a pneumatic, hydraulic or electric impact hammer.

[0033] Furthermore, in order to adapt to different ore sizes and crushing conditions, the present embodiment can adjust the setting position of the vibration device 1.

[0034] Specifically, the vibration device 1 has multiple mounting holes; an adjustment hole array is distributed on the frame along the movement direction of the vibration rod 8, and the number of adjustment holes contained in the adjustment hole array is greater than the number of mounting holes on the vibration device 1; the multiple mounting holes can be aligned one by one with the multiple adjustment holes at different positions in the adjustment hole array.

[0035] Specifically, the device may further include: The plurality of fastening screws 9 correspond to the plurality of mounting holes one by one; the fastening screws 9 are used to fasten the mounting holes and the adjusting holes together when the mounting holes are aligned with the adjusting holes.

[0036] By aligning and fastening the multiple mounting holes of the vibration device 1 with the multiple adjustment holes at different positions in the adjustment hole array, the installation position of the vibration device 1 can be adjusted. By adjusting the position of the vibration device 1, the initial spacing between the fixed plate 3 and the movable plate 2 can be adjusted to meet different ore sizes and crushing conditions, thereby enhancing the adaptability of the device to experiments.

[0037] Specifically, the screening assembly may include: Multiple screens 7 are stacked below the ore crushing zone and connected to multiple support rods 6 of the frame; the mesh size of the upper screen 7 of two adjacent screens 7 is larger than the mesh size of the lower screen 7; the multiple screens 7 are used to screen the ore fragments falling from the ore crushing zone according to a preset particle size; The collecting box 13 is arranged below the screen 7 at the bottom layer.

[0038] The present embodiment does not limit the specific number of the screens 7 , which can be set according to the number of preset particle sizes in practice, and the mesh size of each level of the screen 7 can be set according to the corresponding preset particle size.

[0039] Under the vibration action of multiple screens 7, the ore fragments pass through multiple screens 7 in sequence. Since the mesh sizes of the multiple screens 7 decrease from top to bottom, after screening is completed, the ore fragments collected by the upper screens 7 are larger, and the ore fragments collected by the lower screens 7 are smaller. The ore fragments collected in the collecting box 13 are the smallest, thereby completing the automatic grading and screening of the ore fragments and obtaining a complete graded ore block 14, which is conducive to improving the experimental efficiency and accuracy.

[0040] Specifically, the device may further include: Two baffles 10 are respectively arranged on both sides of the ore crushing area; the baffles 10 are used to close the side opening formed between the fixed plate body 3 and the movable plate body 2.

[0041] By providing the baffle 10, the splashing of ore fragments during the ore crushing process can be effectively prevented, thereby preventing the loss of ore fragments and resulting in incomplete experimental data, and at the same time, it is conducive to improving the safety of the experiment. This embodiment does not limit the specific material and thickness of the baffle 10. For example, the thickness of the baffle 10 can be 1 mm, 1.5 mm, or 2 mm.

[0042] Specifically, the device may further include: The cover plate 4 is arranged to cover the top opening of the space area enclosed by the fixed plate body 3, the movable plate body 2 and the two baffles 10.

[0043] By providing the cover plate 4, the ore crushing area can be further sealed to avoid the splashing of ore fragments.

[0044] When using the device, the cover plate 4 should be opened first, and the ore 5 should be poured into the ore crushing area before the cover plate 4 is closed. In this way, the ore crushing area can be sealed during the ore crushing process to prevent the ore fragments from flying. After the ore crushing process is completed, the cover plate 4 can be opened to check whether all the ore fragments in the ore crushing area have fallen.

[0045] Specifically, the device may further include: The load calculation module is connected to the driving component and is used to determine the ore crushing load according to the working power of the driving component.

[0046] By setting up the load calculation module, the ore crushing load can be calculated accurately and efficiently, improving the accuracy and reliability of the experimental data.
