As an important component of the earth's surface cover, soil not only carries the water, nutrients and microbial communities required for plant growth, but also records the traces of geological historical changes, and has a profound feedback effect on climate change, ecosystem health and the impact of human activities. Therefore, obtaining high-quality and representative soil samples and conducting detailed analysis through scientific means have become the basis and key to research in these fields; There are still the following defects in specific use: 1. When the grinding media (such as spheres) are unevenly stacked in the mill barrel, the materials in some areas may not be effectively ground, resulting in a decrease in the overall grinding efficiency. Secondly, when the grinding media (such as spheres) are unevenly stacked in the mill barrel, the materials in some areas may not be effectively ground, resulting in a decrease in the overall grinding efficiency. In addition, when the grinding media (such as spheres) are unevenly stacked in the mill barrel, the materials in some areas may not be effectively ground, resulting in a decrease in the overall grinding efficiency.

These broken non-soil components may interfere with the accurate analysis of soil components and affect the accuracy of the test results.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention utilizes the placement plate and the arc plate to cooperate with each other, and the circulating oscillation mechanism forms a periodic flow and distribution of the material in the cylinder through periodic oscillation motion, so that the material can be ground more evenly. Enhance the impact force of the grinding medium: During the oscillation process, the grinding medium (sphere) will be subjected to periodic acceleration and deceleration, thereby generating a stronger impact force, which helps to better break the material particles and improve the grinding effect. Improve grinding efficiency: The circulating oscillation mechanism can accelerate the relative movement between the material and the grinding medium, making the contact between them more frequent and sufficient, thereby improving the grinding efficiency. In addition, the oscillation motion also helps to promote friction and collision between material particles, further refining the material particles. Reduce energy consumption and wear: Compared with traditional stirring or turning methods, the circulating oscillation mechanism can reduce energy consumption and wear in some cases. Because the oscillation motion does not require additional components such as stirring paddles or rotors, the complexity and maintenance cost of the equipment are reduced. At the same time, the oscillation motion also helps to reduce the friction and wear between the material and the grinding cylinder, extending the service life of the equipment.

[0017] (2) The present invention utilizes the shovel plate and the fixed sleeve shaft to cooperate with each other, and the track flipping mechanism can further promote the dispersion and mixing of the material in the grinding barrel through mechanical stirring and flipping, so that the contact between the material and the grinding medium is more uniform, thereby improving the grinding efficiency. This uniform contact helps to reduce grinding dead angles and enable the material particles to be more fully ground. Optimizing the grinding effect: The multi-directional flipping action of the track flipping mechanism can make the material subject to impact and shear forces in more directions during the grinding process, thereby more comprehensively crushing the material particles and optimizing the grinding effect. This multi-directional force action helps to reduce the phenomenon of over-grinding or under-grinding of the material and improve the uniformity and quality of the product. Improving grinding efficiency: The track flipping mechanism can accelerate the flow and circulation of the material in the grinding barrel, increase the contact frequency between the grinding medium and the material, and thus improve the grinding efficiency. At the same time, the track flipping mechanism also helps to reduce energy consumption and wear during the grinding process and extend the service life of the ball mill body. For materials with high viscosity or easy to agglomerate, the track flipping mechanism can more effectively promote the dispersion and mixing of the material; for materials with higher hardness, the track flipping mechanism can improve the grinding efficiency by increasing the flipping force; (3) The present invention utilizes the push plate and the inner buckle to cooperate with each other, and the flow guide mechanism enhances the fluidity of the material and forces the material to flow: the opposite movement of the push plate can generate additional driving force, making the material flow more smoothly in the grinding cylinder. This driving force, combined with the axial thrust generated by the impact of the material when the grinding body falls, can more effectively push the material from the feed end to the discharge end. Reduce material accumulation: The existence of the push plate can reduce the accumulation of materials in the grinding cylinder, especially avoid the accumulation of materials in dead corners or low-lying areas, thereby improving the grinding efficiency and the uniformity of material processing. The drainage guide mechanism improves the uniformity of grinding: The opposite movement of the push plate helps to mix the material with the grinding medium more fully, so that the material can be evenly ground in all directions. This helps to improve the fineness and uniformity of the product. The drainage guide mechanism promotes material refinement: By increasing the fluidity and mixing uniformity of the material, the push plate also helps to promote the collision and friction between the material particles, thereby accelerating the material refinement process. The drainage guide mechanism improves the grinding efficiency: The push plate can enhance the fluidity and mixing uniformity of the material, thereby shortening the grinding time and improving the grinding efficiency. At the same time, the push plate also helps to reduce equipment downtime caused by material accumulation, further improving production efficiency. The drainage guide mechanism enhances equipment stability: The presence of the push plate helps to balance the distribution of materials in the grinding drum and reduce vibration and noise caused by uneven material distribution. This helps to extend the service life of the equipment and reduce maintenance costs; BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The complete working principle and steps of the above embodiment are as follows: Initial definition: As an important grinding equipment, the ball mill body 1 is widely used in mining, building materials, chemical industry and other industries. Its basic working process includes multiple links such as material feeding, grinding, and discharging. In the operation of the ball mill body 1, the coordinated operation of various components is crucial; First, the material enters the ball mill body 1 through the feeding device 13, which is usually composed of a feeding pipe and a feeding end cover, and is responsible for uniformly introducing the raw materials into the grinding cylinder 11. The design of the feeding device 13 ensures that the material can enter the grinding cylinder 11 at an appropriate speed and amount, avoiding excessive crowding of the material in the grinding cylinder 11 due to excessive feeding or affecting the grinding efficiency due to insufficient feeding.

[0027] The material entering the grinding cylinder 11 begins to be initially crushed and ground in the grinding cylinder 11. The grinding cylinder 11 in the ball mill body 1 contains grinding media, namely balls. These balls continuously rotate and collide in the grinding cylinder 11, and crush the material with their kinetic energy. The inner lining plate 14 in the grinding cylinder 11 covers the inner wall of the grinding cylinder 11, and protects the inner wall of the grinding cylinder 11 from being worn by the grinding media and materials. At the same time, the surface of the inner lining plate 14 usually has a specific structural design to enhance the grinding effect on the material and improve the operating efficiency of the grinding media.

[0028] During the operation of the ball mill body 1, the transmission device 12 is responsible for driving the rotation of the grinding cylinder 11. Each transmission device generally includes components such as a motor, a reducer, and a transmission shaft. The motor transmits the rotational power to the grinding cylinder 11 through the reducer to drive it to rotate. The configuration design of the transmission device 12 ensures the stable operation and appropriate rotation speed of the grinding cylinder 11, thereby effectively improving the grinding efficiency.

[0029] During the rotation of the grinding drum 11, the balls are lifted to a certain height and then fall down under the action of gravity, generating strong impact and shear forces. This force causes the materials to be continuously crushed and ground. The grinding effect of the ball mill body 1 depends not only on the rotation speed of the grinding drum 11, but also on the size and number of the balls and the wear of the inner lining plate 14.

[0030] In the grinding process, the inner lining plate 14 also plays an important role. The design of the inner lining plate 14 is usually optimized according to the properties of the material and the operating characteristics of the grinding drum 11. The material of the inner lining plate 14 is generally selected from metal or ceramic materials with strong wear resistance to ensure that it is not easy to wear during long-term use and can maintain good grinding performance. The structural design of the inner lining plate 14 also includes different shapes and arrangements to achieve the best grinding effect and improve the movement efficiency of the material.

[0031] The fully ground material is finally discharged from the other end of the grinding cylinder 11. The discharge device 3 is generally set corresponding to the feeding device, and the ground material is transported to the subsequent processing link through the discharge pipe. The design of the discharge device should ensure that the material can be discharged smoothly and avoid blockage.

[0032] In general, the working process of the ball mill body 1 is a complex and sophisticated system engineering, and the synergy of various components is crucial. The rotation of the grinding cylinder 11, the movement of the ball, the protection of the lining plate 14, the drive of the transmission device 12, and the coordination of the feeding and discharging devices together ensure the efficient operation and stable performance of the ball mill body 1. In actual operation, the operator needs to regularly check and maintain various components to ensure the normal operation of the ball mill and extend the service life of the equipment; When using: The cyclic oscillation mechanism 2 is used to generate periodic acceleration and deceleration of the grinding medium in the grinding cylinder 11 through periodic oscillating motion. Steps: like Figures 2 to 4 As shown, when the material entering the grinding cylinder 11 begins to be initially crushed and ground in the grinding cylinder 11, and the transmission device 12 is responsible for driving the rotation of the grinding cylinder 11, the pinion 22 fixedly connected to the output end of the shaft on one side of the transmission device 12 will rotate synchronously with the rotation of the grinding cylinder 11 driven by the transmission device 12, thereby the internal gear 23 meshing with the pinion 22 will also rotate with the rotation of the pinion 22, and thus the external gear 24 fixedly connected to the outer surface of the internal gear 23 will also rotate with the internal gear 23, so that the arc plate 25 meshing with the outer wall of the external gear 24 will deflect and displace with the rotation of the external gear 24. , and the placement plate 26 fixedly connected to the outer surface of the arc plate 25 will also deflect and displace along with the deflection displacement of the placement plate 26, so the transfer rod 27 fixedly connected to the outer wall of one end of the placement plate 26 will also rotate on the outer wall of the pinion 22 along with the deflection displacement of the arc plate 25. In summary, when the grinding medium ball is lifted to a certain height along with the rotation of the grinding cylinder 11, and then falls freely or rolls on the grinding cylinder 11, the grinding medium ball will fall into the through groove opened inside the placement plate 26, and then along with the deflection displacement of the placement plate 26 against the inner wall surface of the lining plate 14, the grinding medium ball will form a periodic flow and distribution; The track turning mechanism is used to make the contact between the material and the grinding medium more frequent and sufficient through multi-directional turning and stirring. 3 steps: like Figures 5 and 6 As shown, when the outer gear 24 rotates, the eccentric gear 31 fixedly connected to the outer wall of one side of the outer gear 24 will also rotate, making the outer gear 24 more stable, and then the front crank 33 eccentrically fixedly connected to the outer wall of one side of the eccentric gear 31 will also rotate, so that the rotation of the front crank 33 will also drive the fixed inclined rod 34 fixedly connected to the outer surface of one end of the front crank 33 to rotate, and the rotation of the fixed inclined rod 34 will also drive the rear crank 36 rotatably connected to one end of the fixed inclined rod 34 to rotate on the inner wall of one end of the sleeve rod housing 32, thereby the alternating rotation of the front crank 33 and the rear crank 36 will The fixed sleeve shaft 35 slidably connected to the outer wall of the fixed inclined rod 34 slides on the outer wall of the fixed inclined rod 34, and at the same time, the external connection column 37 fixedly connected to one end of the fixed sleeve shaft 35 drives the shovel plate 38 fixedly connected to one end of the external connection column 37 to move on the inner wall surface of the inner lining plate 14, so that the movement stroke of the shovel plate 38 is a displacement movement trajectory around the external connection column 37 slidingly connected to the inner wall of the sleeve rod housing 32. In summary, the grinding media accumulated on the inner surface of the inner lining plate 14 are rolled through the arc movement trajectory of the shovel plate 38, so as to promote the dispersion and mixing of the materials in the grinding cylinder 11; The flow guiding mechanism is used to improve the flow guidance of materials so that the materials can flow more smoothly from the feed end to the discharge end. 4 steps: like Figures 7 and 8 As shown, when the transfer rod 27 rotates on the outer wall of the pinion gear 22, the connecting shaft 41 connected to the outer wall of one side of the transfer rod 27 will also rotate, so that the threaded rod 42 fixedly connected to the outer wall of one end of the connecting shaft 41 will also rotate with the rotation of the connecting shaft 41, and then the sleeve 43 forming a ball screw structure with the outer wall of the threaded rod 42 will slide on the outer wall of the threaded rod 42 to the side away from the transfer rod 27, thereby the movement of the sleeve 43 will cause the connecting rod 45 connected to the inner wall of the outer buckle 44 to move toward the side close to the threaded rod 42, so that the wedge rod 46 connected to the outer wall of one end of the connecting rod 45 will be deflected and expanded outwardly, so the outward deflection and expansion of the wedge rod 46 will pull the inner buckle 47 and the push plate 48 to deflect and move outwardly, and the outward deflection and expansion of the wedge rod 46 will also pull the telescopic shaft 49 to shrink. In summary, the outward deflection and movement of the push plates 48 distributed opposite to each other enhances the contact frequency between the material and the grinding medium. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
