Description

Technical Field

[0001] This invention relates to a material crushing device, and more particularly to a fully automatic grinding device for geological samples. Background Technology

[0002] In mineral geological exploration and analysis, to accurately determine the chemical composition and mineral structure of ores, it is often necessary to perform step-by-step crushing and grinding of collected rock and mineral samples to achieve the fineness required for laboratory analysis. The traditional sample crushing and processing flow usually includes multiple steps: first, large pieces of ore are crushed into smaller particles using coarse crushing equipment; then, they are gradually processed into fine sand through medium crushing, fine crushing, and other stages; and finally, they are ground into uniform powder using grinding equipment.

[0003] For ordinary crushers such as jaw crushers and double roll crushers, only medium crushing can be achieved. For fine crushing, grinding drums are usually required. For laboratories in research institutes, universities, or other geological exploration units, the number of samples is particularly large, and the current grinding equipment cannot meet the demand. Increasing output by purchasing new equipment and adding manpower would increase production costs, especially labor costs.

[0004] Currently, after sampling in the field, geological exploration units typically need to transport the samples to a fixed location for crushing and processing. A common practice is to temporarily rent factory buildings locally, install various crushing equipment, and set up temporary processing workshops. This approach has several drawbacks: First, renting sites and constructing supporting facilities increases project costs; second, different exploration projects are often located in different areas, and each time the work site is moved, it is necessary to find new factory buildings, relocate and install equipment, which is time-consuming and labor-intensive, affecting exploration efficiency; third, the transportation of samples from the collection point to the processing site may increase the risk of sample loss, confusion, or contamination, and is also not conducive to obtaining rapid analytical results on-site.

[0005] Therefore, there is an urgent need for a sample grinding device with high production efficiency and a high degree of automation, capable of operating in the field. Summary of the Invention

[0006] In view of this, and in order to solve the problem, the present invention provides a fully automated grinding device for geological samples, the specific technical solution of which is as follows: An automated geological sample grinding device is characterized by comprising a grinding bed, a robot, a worktable, and a grinding cylinder. The grinding bed includes a bed and rollers. Multiple rollers are arranged in parallel and mounted on the bed. The grinding cylinder is placed on the rollers, and the rollers drive the grinding cylinder to rotate. The robot is used to move the grinding cylinder, and a mechanical gripper is installed at the end of the robot to grasp the grinding cylinder. A sample funnel is placed on the worktable, and a container is placed below the funnel to hold the sample. The robot removes the grinding cylinder from the grinding bed and pours the material and grinding rods together into the funnel, the lower opening of which is smaller than the grinding rods. The grinding cylinder includes a cylinder body and a lid, and several grinding rods are placed inside the grinding cylinder. When a mineral sample is placed inside the cylinder, the sample is crushed by the impact of the grinding rods as the grinding cylinder rotates at high speed.

[0007] In the aforementioned grinding machine, two rollers form a group, and at least one roller in each group is a drive roller, which is driven to rotate by an electric motor. The gap width between the two rollers in the same group is smaller than the outer diameter of the grinding cylinder.

[0008] In the rollers described above, at least one roller in each group of rollers is provided with an annular flange. Depending on the number of grinding cylinders to be placed on the roller, multiple annular flanges are provided at both ends and in the middle of the roller. The space between two adjacent annular flanges is used to place the grinding cylinders.

[0009] The number of rollers mentioned above is 12 in six groups, numbered from group 1 to group 6 in order of position. The drive roller of group 3 or 4 is directly driven by an electric motor, and the power is then transmitted to the drive rollers of other groups through belts, chains, gears or other transmission structures, thereby driving all drive rollers to rotate synchronously.

[0010] The rollers mentioned above are polyurethane-coated rollers.

[0011] There are two grinding machines as described above.

[0012] The aforementioned mechanical gripper includes two opposing V-shaped blocks, which grip and release the grinding cylinder by opening and closing the two V-shaped blocks.

[0013] The aforementioned mechanical gripper also includes a mounting flange, a mounting plate, a slide rail, and a cylinder. The mechanical gripper is mounted on the robot via the mounting flange. The slide rail is mounted on the mounting plate, and the V-blocks are equipped with sliders that match the slide rail. The two V-blocks slide along the inside and outside of the slide rail. The movement of the two V-blocks is driven by the cylinder.

[0014] It also includes a dust removal device, which is equipped with a negative pressure exhaust pipe, and the air inlet of the negative pressure exhaust pipe is located at the funnel.

[0015] The aforementioned grinding machine, robot, and workbench are integrated into a container or carriage, allowing the entire device to be moved with the vehicle.

[0016] Compared with the prior art, the present invention has the following outstanding advantages: 1. The grinding machine has a simple structure, large load capacity, and can grind multiple samples at once; 2. High degree of automation, saving labor costs; 3. It has a compact structure, can be installed in a vehicle, is easy to move, and can be processed on-site at different collection points. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to its embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of protection of the invention.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] like Figure 1-5 As shown, the present invention includes a grinding machine 3, a robot 4, a worktable 2, a grinding cylinder 7, and a dust removal device.

[0028] The structure of the grinding bed 3 is as follows: Figure 2 , 3 As shown, the system includes a bed 5 and rollers 6. Multiple rollers 6 are arranged in parallel and mounted on the bed 5. The grinding cylinder 7 is placed on the rollers 6, and the rollers 6 drive the grinding cylinder 7 to rotate. Two rollers 6 form a group, and at least one roller in each group is a drive roller, meaning it is driven by an electric motor. The gap between two rollers 6 in the same group is smaller than the outer diameter of the grinding cylinder 7. In use, multiple grinding cylinders 7 are placed on two rollers 6 in the same group, and the electric motor drives the rollers 6 to rotate, thereby driving the grinding cylinder 7 to rotate at high speed, achieving the grinding of the mineral sample.

[0029] At least one roller 6 in each group of rollers 6 is provided with an annular flange 8. For example... Figure 3 As shown, multiple annular flanges 8 are provided at both ends and in the middle of the roller 6 according to the number of grinding cylinders 7 to be placed on the roller 6. The position between two adjacent annular flanges 8 is used to place the grinding cylinders 7. The annular flanges 8 stop the grinding cylinders 7 at both ends to prevent axial movement when the grinding cylinders 7 rotate. At the same time, there is a certain gap between adjacent grinding cylinders 7, which facilitates the robot 4 to pick up and put in. When the robot 4 places the grinding cylinders 7 on the grinding bed 3, since there is a certain gap at both ends of the grinding cylinders 7, the grinding cylinders 7 will not collide with the grinding cylinders 7 at both ends due to accuracy deviation, and the accuracy requirements of the robot 4 are also relatively low. In this embodiment, five grinding cylinders 7 are placed on each group of rollers 6.

[0030] The number of rollers 6 is 12 in six groups, which are numbered 1 to 6 in order of position. The motor directly drives the active roller of the 3rd or 4th group, and then transmits the power to the active rollers of other groups through belts 9, chains, gears or other transmission structures, thereby driving all the drive rollers to rotate synchronously.

[0031] The roller 6 is a polyurethane-coated roller. The polyurethane increases the friction between the roller 6 and the grinding cylinder 7, reducing the impact force between them.

[0032] There are two grinding beds 3.

[0033] The robot 4 is used to transport the grinding cylinder 7, and a mechanical gripper is installed at the end of the robot 4 to grasp the grinding cylinder 7. Figure 4 As shown, the mechanical gripper includes two opposing V-shaped blocks 13, which grip and release the grinding cylinder 7 by opening and closing. The mechanical gripper also includes a mounting flange 10, a mounting plate 12, a slide rail 14, and a cylinder 11. The mechanical gripper is mounted on the robot 4 via the mounting flange 10. The slide rail 14 is mounted on the mounting plate 12, and the V-shaped blocks 13 are equipped with sliders that match the slide rail 14. The two V-shaped blocks 13 slide inwards and outwards along the slide rail 14. The cylinder 11 drives the movement of the two V-shaped blocks 13.

[0034] The grinding cylinder 7 includes a cylinder body and a lid, and several grinding rods are placed inside the grinding cylinder 7. When a mineral sample is placed inside the cylinder, the mineral sample is crushed by the impact of the grinding rods when the grinding cylinder 7 rotates at high speed.

[0035] The electrical control devices for each piece of equipment are housed inside the workbench 2. It can also be used for sample loading; a sample loading funnel 15 is placed on the workbench 2, and a container 16 is placed below the funnel 15 to hold the sample. The robot 4 removes the grinding cylinder 7 from the grinding bed 3 and pours the material and grinding rod together into the funnel 15. The lower opening of the funnel 15 is smaller than the grinding rod, so the material falls from the funnel 15 into the container 16, while the grinding rod remains in the funnel 15, thus separating the grinding rod from the material.

[0036] The dust removal device is equipped with a negative pressure exhaust pipe, the air inlet of which is located at the funnel 15. Dust generated during the material pouring process is drawn into the negative pressure exhaust pipe and sent into the dust removal device for purification.

[0037] To facilitate on-site sampling operations, the grinding machine 3, robot 4, workbench 2, and dust removal device are integrated into a container 1 or truck. The entire device can be transported by vehicle for on-site operation in the field.

[0038] The grinding machine 3 has a simple structure and a large load capacity, making it particularly suitable for grinding mineral samples in large batches.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
