[0002] In soil analysis and research, thorough grinding of soil samples is a crucial prerequisite for obtaining accurate experimental data. Currently, commonly used soil grinding devices have several shortcomings. Some devices have poorly designed grinding mechanisms, resulting in uneven stress on the soil sample during grinding, leading to a wide particle size distribution after grinding, which is insufficient for high-precision experiments. Furthermore, the spacing between the upper and lower grinding components of many devices is inconvenient to adjust, requiring manual adjustment, which is not only cumbersome and labor-intensive but also makes it difficult to ensure adjustment accuracy, affecting grinding efficiency and quality. Simultaneously, the drive mechanisms of some devices have poor stability and are prone to failure during prolonged operation, reducing the equipment's lifespan. Moreover, some devices lack effective sound insulation and protective measures, generating significant noise during grinding, adversely affecting the operator's working environment and posing certain safety hazards. Summary of the Invention

[0034] A soil grinding device.
[0035] This implementation plan addresses the technical problems existing in the prior art, such as those disclosed in the background section above: "In the process of soil analysis and research, thorough grinding of soil samples is an important prerequisite for obtaining accurate experimental data. Currently, commonly used soil grinding devices have many shortcomings. The grinding mechanism of some devices is poorly designed, resulting in uneven force on the soil sample during grinding, leading to a wide particle size distribution after grinding, which is difficult to meet the requirements of high-precision experiments. In addition, the spacing between the upper and lower grinding parts of many devices is inconvenient to adjust, requiring manual adjustment, which is not only cumbersome and labor-intensive, but also makes it difficult to ensure adjustment accuracy, affecting grinding efficiency and quality. At the same time, the drive mechanism of some devices has poor stability and is prone to failure during long-term operation, reducing the service life of the equipment. Moreover, some devices lack effective sound insulation and protection measures, generating significant noise during grinding, which adversely affects the working environment of operators and also poses certain safety hazards." In practical terms, this problem is obviously a real and difficult-to-solve issue. Therefore, to solve this technical problem, a soil grinding device is provided.
[0036] like Figure 1-4 As shown in the figure;
[0037] This invention provides a technical solution: a soil grinding device, including a support base 1, a partition 2 welded at the center of the support base 1, a lifting mechanism 3 fixed to the support base 1 on the left side of the partition 2 by bolts, a protective cover 4 fixed to the outside of the lifting mechanism 3 by bolts, a control panel 5 fixed to the partition 2 by screws, a lower planetary grinding mechanism 6 provided on the support base 1 on the right side of the partition 2, and an integrated enclosure 7 fixed to the outside of the mechanism by bolts, and an upper cover 9 installed on the side wall of the partition 2 by a pair of guide mechanisms 8, and an upper grinding mechanism 10 provided on the upper cover 9.
[0038] The guiding mechanism 8 includes a guide rail 11 fixed to the side wall of the partition 2 by bolts. The guide rail 11 is a T-shaped guide rail. A guide block 12 that can slide up and down is snapped onto the guide rail 11. A T-shaped groove adapted to the T-shaped guide rail is opened on the guide block 12. A mounting seat 13 for fixing the upper cover 9 is welded between the two guide blocks 12. The upper cover 9 is fixed to the mounting seat 13 by bolts.
[0039] The lifting mechanism 3 includes a support plate 31 bolted to the support base 1. A geared motor 32, a servo geared motor, is bolted to the side wall of the support plate 31 and is equipped with an encoder. A driven gear 33 is mounted on the other side of the support plate 31 via a bearing housing. The output shaft of the geared motor 32 passes through the support plate 31 and is connected to a driving gear 34 via a key. The driving gear 34 and the driven gear 33 are connected by a toothed belt 35. A guide rail 36 is also bolted to the support plate 31. A sliding guide block 37 is engaged on the guide rail 36. A retainer 38 is bolted to the toothed belt 35. A connecting seat 39 is welded between the guide block 37 and the retainer 38. The connecting seat 39 is bolted to the mounting base 13, and a spring washer is fitted over the bolt. Both the driven gear 33 and the driving gear 34 are made of 45# steel and have a hardened layer on their surface.
[0040] The lower planetary grinding mechanism 6 includes a drive motor that is fixed to the support base 1 by bolts. The output shaft of the drive motor is connected to a planetary gear train through a coupling. A grinding disc is mounted on the planetary gear train by bolts.
[0041] The inner side of the integrated fence 7 has a sound insulation layer glued on it, and the sound insulation layer is made of sound-absorbing cotton.
[0042] The upper grinding mechanism 10 includes a mounting bracket that is bolted to the bottom of the upper cover 9. A grinding head is mounted on the mounting bracket via a bearing. The grinding head is adapted to the grinding disc of the lower planetary grinding mechanism 6.
[0043] An observation window is fixed to the protective cover 4 by bolts. The observation window is made of transparent acrylic sheet.
[0044] Working principle:
[0045] The working process of this soil grinding device mainly includes two stages: the lifting and lowering adjustment of the upper grinding mechanism and the grinding of the soil sample.
[0046] Before soil grinding, the distance between the upper grinding mechanism and the lower planetary grinding mechanism needs to be adjusted according to the characteristics of the soil sample and the grinding requirements. At this point, the lifting mechanism begins operation: the geared motor starts, and its output shaft drives the drive gear to rotate. The drive gear, through a toothed belt, drives the driven gear to rotate synchronously. Since the chuck is fixed to the toothed belt, the movement of the toothed belt causes the chuck to move up and down. The chuck, through the connecting seat, drives the guide block to slide on the guide rail. Simultaneously, the connecting seat drives the mounting base and the upper cover to move up and down, thus achieving the lifting and lowering of the upper grinding mechanism. The encoder on the servo geared motor can detect the motor's rotation angle and speed in real time. Through the control panel, the lifting height of the upper grinding mechanism can be precisely adjusted to ensure that the distance between the upper grinding mechanism and the lower planetary grinding mechanism meets the grinding requirements.
[0047] After the spacing is adjusted, the soil sample is placed on the grinding disc of the lower planetary grinding mechanism, and both the lower and upper grinding mechanisms are started. The drive motor of the lower planetary grinding mechanism starts, and its output shaft drives the planetary gear system to rotate. The planetary gear system drives the grinding disc to perform planetary motion (i.e., the grinding disc rotates both around its own axis and revolves around the central axis of the planetary gear system). At the same time, the grinding head of the upper grinding mechanism rotates under the drive of the corresponding drive device (if the upper grinding mechanism adopts a passive rotation method, it rotates under the friction with the soil on the grinding disc). The planetary motion of the grinding disc and the rotational motion of the grinding head work together on the soil sample, subjecting the soil sample to multi-directional shear force, compressive force, and frictional force, thereby thoroughly grinding the soil sample.
[0048] During the grinding process, the sound-absorbing cotton insulation layer inside the integrated enclosure absorbs most of the noise generated during grinding, reducing the noise impact on the environment. The protective cover prevents parts from falling off during the operation of the lifting mechanism and causing injury to the operators. Operators can also observe the operating status of the lifting mechanism through the transparent acrylic observation window on the protective cover. The T-shaped guide rails of the guide mechanism cooperate with the T-shaped grooves of the guide blocks to ensure the stability of the upper cover and upper grinding mechanism during the grinding process, preventing shaking from affecting the grinding effect.
[0049] After grinding is complete, turn off the lower planetary grinding mechanism and the upper grinding mechanism. Then, use the lifting mechanism to raise the upper grinding mechanism and remove the ground soil sample.
[0050] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
