Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring, and in particular to a rotary shaking device for soil testing. Background Technology

[0002] Rotary mixing equipment for soil testing is mainly used in the sample pretreatment stage of soil testing. It provides a uniformly mixed sample for subsequent analysis of indicators such as heavy metals, nutrients, and organic matter. It is widely used in environmental monitoring, agricultural science, third-party testing, and geological exploration industries. Its core function is to make the soil sample fully contact and mix with the extractant and reagents through controllable rotational motion, thereby eliminating local concentration differences in the sample.

[0003] Currently, the rotary mixing equipment for soil testing on the market mainly consists of a drive motor, a rotating support, a sample fixing fixture, a speed adjustment panel, and a safety protective shell. It mainly achieves sample mixing without stratification and uniform component distribution by setting a stable rotation rate and continuous rotation time, thereby ensuring the accuracy and repeatability of subsequent test data.

[0004] Existing rotary mixing devices for soil testing mostly adopt a single-direction rotation and mixing design, which easily causes the sample to form a fixed circulation in the container, resulting in mixing dead zones or local stratification. This design makes it difficult for soil particles to achieve full and comprehensive contact with reagents, resulting in insufficient mixing uniformity, which may ultimately affect the stability and accuracy of subsequent soil testing data. Therefore, a rotary mixing device for soil testing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rotary shaking device for soil testing, which aims to improve the problem that a single-direction rotary shaking design can easily cause the sample to form a fixed circulation in the container, resulting in mixing dead zones or local stratification.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rotary shaking device for soil testing, comprising a support body, a power component provided on the top of the support body, a control component fixedly connected to the top of the support body, a transmission shaft rotatably connected inside the support body, a fixing mechanism provided at both ends of the transmission shaft, and a sample container fixedly connected inside the fixing mechanism.

[0007] The fixing mechanism includes a longitudinal frame, which is fixedly connected to both ends of the drive shaft. A transverse frame is fixedly connected to the outside of the longitudinal frame. A cover plate is rotatably connected to the top of the longitudinal frame. A latch is fixedly connected to the outside of the longitudinal frame. A buckle is fixedly connected to the outside of the cover plate. The latch and the buckle are compatible with each other.

[0008] As a further description of the above technical solution:

[0009] A first bevel gear is fixedly connected to the outside of the drive shaft, and a second bevel gear is rotatably connected to the top of the support body. The power assembly includes a stepper motor, which is fixedly connected to the top of the support body. The output end of the stepper motor is fixedly connected to the outside of the second bevel gear through the support body. The second bevel gear and the first bevel gear mesh.

[0010] As a further description of the above technical solution:

[0011] A protective shell is fixedly connected to the top of the support body. Several ventilation slots are opened on the outer wall of the protective shell, and the stepper motor is located inside the protective shell.

[0012] As a further description of the above technical solution:

[0013] The bottom of the support is fixedly connected with four shock-absorbing pads.

[0014] As a further description of the above technical solution:

[0015] A display panel is fixedly connected to the outside of the control component, and an adjustment switch is also fixedly connected to the outside of the control component.

[0018] As a further description of the above technical solution:

[0019] The drive shaft is located at the center of the support body, and the stepper motor is located at the top center of the support body.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by setting the fixing mechanism to an inclined state, when the sample container rotates, the soil sample and reagent inside not only make circular motions but also flip up and down, achieving multiple shaking angles and solving the problem of dead angles in traditional single-direction shaking; the transmission shaft drives the fixing mechanisms at both ends to rotate synchronously on both sides, ensuring uniform mixing; the shock-absorbing pad at the bottom of the support absorbs vibration, and the component center layout distributes forces evenly, improving the stability of the device operation; the protective shell protects the stepper motor, and the ventilation slot assists in heat dissipation, reducing motor wear and extending the overall life of the equipment.

[0022] 2. In this utility model, the fixing mechanism adopts a rotatable cover plate with a matching structure of latch and buckle. No complicated operation is required. Simply rotate the cover plate to separate or engage the buckle and latch, and the sample container can be quickly loaded and unloaded, realizing quick disassembly and quick assembly.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3An embodiment of this utility model is provided: a rotary shaking device for soil testing, including a support body 1, a power component 2 is provided on the top of the support body 1, a control component 3 is fixedly connected to the top of the support body 1, a transmission shaft 6 is rotatably connected inside the support body 1, a fixing mechanism 4 is provided at both ends of the transmission shaft 6, and a sample container 5 is fixedly connected inside the fixing mechanism 4.

[0033] The support body 1 provides basic support for the entire device, ensuring stable installation of all components; the control component 3 can receive operation commands and regulate the operating status of the power component 2. After the power component 2 is started, it outputs power to drive the transmission shaft 6 to rotate inside the support body 1. The transmission shaft 6 then drives the fixing mechanisms 4 at both ends to rotate synchronously. The sample container 5 fixed inside the fixing mechanism 4 moves together with the fixing mechanism 4, so that the soil sample and reagent in the container are mixed during the rotation, providing a uniform sample for subsequent testing.

[0034] Reference Figures 1-5 The fixing mechanism 4 includes a longitudinal frame 12, which is fixedly connected to both ends of the drive shaft 6. A transverse frame 16 is fixedly connected to the outside of the longitudinal frame 12. A cover plate 13 is rotatably connected to the top of the longitudinal frame 12. A latch 14 is fixedly connected to the outside of the longitudinal frame 12. A buckle 15 is fixedly connected to the outside of the cover plate 13. The latch 14 and the buckle 15 are compatible.

[0035] The longitudinal frame 12 and the transverse frame 16 together form the support structure of the fixing mechanism 4, providing a space for the sample container 5. After the sample container 5 is placed in, the cover plate 13 is rotated to cover the top of the longitudinal frame 12. Through the matching and engagement of the latch 14 and the buckle 15, the cover plate 13 can be firmly fixed on the longitudinal frame 12, thereby stably limiting the sample container 5 within the fixing mechanism 4, preventing the sample container 5 from shifting or falling off during the equipment shaking process, and ensuring the stability of the mixing process.

[0036] Reference Figures 1-3 The transmission shaft 6 is externally fixedly connected to a first bevel gear 7, and the support body 1 is rotatably connected to a second bevel gear 11. The power assembly 2 includes a stepper motor 10, which is fixedly connected to the top of the support body 1. The output end of the stepper motor 10 is fixedly connected to the outside of the second bevel gear 11 through the support body 1. The second bevel gear 11 and the first bevel gear 7 mesh.

[0037] When the control component 3 issues a start command, the stepper motor 10 starts to run, and its output directly drives the second bevel gear 11 to rotate on the top of the support body 1. Since the second bevel gear 11 meshes with the first bevel gear 7 outside the transmission shaft 6, the rotational power of the second bevel gear 11 is transmitted to the first bevel gear 7, which in turn drives the transmission shaft 6 to rotate synchronously, realizing the transmission of power from the stepper motor 10 to the transmission shaft 6, providing a power basis for the rotation of the fixed mechanism 4.

[0038] Reference Figures 1-3 The top of the support body 1 is fixedly connected to a protective shell 8. The outer wall of the protective shell 8 is provided with several ventilation slots 9. The stepper motor 10 is located inside the protective shell 8.

[0039] The protective shell 8 encloses the stepper motor 10, preventing external dust, debris, or accidental collisions from damaging the stepper motor 10 and providing protection. At the same time, the stepper motor 10 generates heat during long-term operation. The ventilation slots 9 on the outer wall of the protective shell 8 form an air circulation channel, allowing the heat generated by the motor to be dissipated to the outside through the ventilation slots 9, preventing the stepper motor 10 from overheating and causing performance degradation or damage, and ensuring stable operation of the motor.

[0040] Reference Figure 6 The bottom of the support body 1 is fixedly connected with four shock-absorbing pads 19;

[0041] When the equipment is running, the stepper motor 10 runs and the drive shaft 6 rotates, which will cause the whole to vibrate. The four shock-absorbing pads 19 at the bottom of the support body 1 can absorb the vibration energy generated by the equipment through their own deformation, reduce the impact of vibration on the overall stability of the equipment, and prevent the drive shaft 6 from rotating and shifting due to vibration, and the sample in the sample container 5 from splashing out. At the same time, it can also reduce the noise generated by the vibration of the equipment and create a more stable working environment.

[0042] Reference Figures 1-2 The control component 3 is externally fixedly connected to a display panel 17, and the control component 3 is externally fixedly connected to an adjustment switch 18;

[0043] Operators can input shaking parameters to control component 3 via adjustment switch 18. After receiving the parameters, control component 3 can precisely regulate the operation of power component 2. Display panel 17 is linked with control component 3 and can display the current operating status of the equipment in real time, allowing operators to intuitively understand the equipment's working status. If parameters need to be adjusted, they can be modified in a timely manner via adjustment switch 18 to ensure that the shaking process meets the sample processing requirements for soil testing.

[0044] Reference Figure 1 The fixed mechanism 4 is tilted at a 45-degree angle;

[0045] After the fixing mechanism 4 is tilted, the sample container 5 fixed inside it is tilted at a 45-degree angle together with the fixing mechanism 4. When the drive shaft 6 drives the fixing mechanism 4 to rotate, the soil sample and reagent in the sample container 5 will not only move in a circular motion with the container, but will also be flipped up and down due to the tilt angle. This avoids the sample mixing dead angle caused by single horizontal rotation, so that the soil sample and reagent can come into more contact and collide, improve the uniformity of shaking, and solve the problem of poor shaking effect in traditional single direction.

[0046] Reference Figures 1-3The drive shaft 6 is located at the center of the support body 1, and the stepper motor 10 is located at the top center of the support body 1.

[0047] The drive shaft 6 is located at the center of the support body 1, which ensures that the distances from the fixing mechanisms 4 at both ends to the edge of the support body 1 are consistent, ensuring that the force on both ends of the drive shaft 6 is balanced when it rotates, and avoiding the drive shaft 6 from jamming or shaking due to the shift of the center of gravity. The stepper motor 10 is located at the top center of the support body 1, which ensures that the second bevel gear 11 and the first bevel gear 7 outside the drive shaft 6 are in a precise meshing position, reducing the loss in the power transmission process, and ensuring that the power generated by the motor can be evenly applied to the drive shaft 6, further improving the stability of the rotation of the drive shaft 6 and providing a smooth power output for sample shaking.

[0048] Working principle: The operator first inputs the shaking parameters to the control component 3 through the adjustment switch 18 outside the control component 3. The display panel 17 outside the control component 3 then displays the current operating status of the equipment in real time. After that, the control component 3 receives the parameters and regulates the power component 2 to start running. The stepper motor 10 in the power component 2 starts to run. The output end of the stepper motor 10 drives the second bevel gear 11, which is rotatably connected to the top of the support body 1, to rotate. Since the second bevel gear 11 meshes with the first bevel gear 7, which is fixedly connected to the outside of the drive shaft 6, the rotational power of the second bevel gear 11 is transmitted to the first bevel gear 7, thereby driving the drive shaft 6 to rotate synchronously. The fixing mechanism 4 set at both ends of the drive shaft 6 is in a 45-degree inclined state. Its longitudinal frame 12 is fixedly connected to both ends of the drive shaft 6. The transverse frame 16 is fixedly connected to the outside of the longitudinal frame 12. Together with the longitudinal frame 12, it forms a support structure. The cover plate 13, which is rotatably connected to the top of the longitudinal frame 12, is adapted to engage with the buckle 15, which is fixedly connected to the outside of the cover plate 13, through the latch 14 fixedly connected to the outside of the longitudinal frame 12. This stabilizes the sample container 5 inside the fixing mechanism 4 and rotates together with the drive shaft 6. Under the tilting and rotating action of the fixing mechanism 4, the soil sample and reagents in the sample container 5 not only move in a circular motion with the container, but also flip up and down due to the tilt angle, avoiding the mixing dead angle of a single horizontal rotation and achieving full contact and mixing. At the same time, the four shock-absorbing pads 19 fixedly connected to the bottom of the support body 1 absorb the vibration generated by the operation of the equipment through their own deformation, reducing the impact of vibration on the overall stability of the equipment, preventing the drive shaft 6 from rotating and shifting or the sample in the sample container 5 from splashing out, and finally providing a uniform sample for subsequent soil testing.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
