Description

Technical Field

[0001] The utility model relates to the technical field of soil sample preparation, in particular to an automatic soil sampling quartering device. Background Art

[0002] For technicians in the agricultural field, soil is the main research object. The enzyme activity, microorganisms and various components in the soil can reflect the growth environment of crops cultivated in the soil, and therefore analyze and study the factors affecting crop yield. Usually, the soil needs to be prepared for sample preparation, that is, the soil samples are collected from the field and then mixed, dried, ground and sieved, and then prepared into soil samples for observation and experiments. The soil taken needs to be prepared by reducing the soil samples according to existing standards, usually by quartering. Quartering refers to mixing the collected samples and laying them flat into a square, then drawing a diagonal line to divide them into four equal parts, taking two of the diagonal parts, and discarding the other two parts. If the obtained sample is still large, it can be processed by quartering again until the required quantity is obtained.

[0003] To this end, Chinese Patent Publication No. CN220120496U discloses a four-part separator for soil sample preparation, which relates to the technical field of soil sample preparation. The four-part separator for soil sample preparation includes an upper frame, the bottom end of which is tightly plugged into a lower frame, a limiting mechanism is provided on the inner walls of the upper and lower frames, and a separator is placed inside the upper and lower frames. The separator includes an annular baffle, the outer wall of which contacts the inner side wall of the upper frame, the upper and lower ends of the annular baffle are through-shaped, and two sets of intersecting partitions are fixedly connected to the inner side wall of the annular baffle. The device can evenly divide soil samples into four parts, solving the problems of inaccurate manual separation and inconsistency between samples, and meets the requirements of multi-point sampling and mixed use. It has fast sampling speed and high efficiency, can meet the needs of different users, and at the same time, soil samples are completed in a closed system, and the sample preparation process is clean and complete.

[0004] However, the existing technology does not mix the soil uniformly when preparing it, which may lead to large differences in soil samples and affect the true properties of the soil samples. The existing technology also requires more human participation when dividing the soil samples into four equal parts, which leads to deviations in the uniformity of the soil samples. The deviations in the equal division of soil samples also indirectly affect the experimental or test data. At the same time, the operation of the existing technology is also relatively cumbersome, not easy to move, and is not suitable for use in various scenarios. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figures 1-8 As shown, a soil sampling automatic quartering device includes a chassis 1, a support column 11 is fixed to the surface of the chassis 1, and a rotating shaft seat 12 is provided on one side of the support column 11. The automatic quartering device also includes a fixing frame 2, a driving frame 3, a mixing component 4 and a quartering component 5. The fixing frame 2 is installed above the chassis 1 through a vertical rod, and the fixing frame 2 is parallel to the chassis 1. The driving frame 3 is arranged parallel to the above the fixing frame 2 for installing the driving device. The mixing component 4 is installed on the driving frame 3 for mixing the soil sample evenly. The quartering component 5 is installed at the bottom of the mixing component 4, including a sampling tray 51. Four partition plates 52 are installed inside the sampling tray 51. The four partition plates 52 divide the internal space of the sampling tray 51 into four equal parts.

[0028] The device first loads the soil sample to be prepared into the mixing component 4, mixes it through the mixing component 4, and then transfers it to the sampling tray 51 of the quarter component 5. Since the sampling tray 51 is directly below the mixing component 4, when the soil sample is transferred to the sampling tray 51, it will be automatically and evenly divided into four equal parts by the four partition plates 52 in the sampling tray 51, solving the problems of randomness and unevenness in soil sampling and improving the accuracy of the experiment.

[0029] like Figure 2 、 Figure 4 and Figure 5 As shown, the quad assembly 5 also includes a rotating disk 53, which is sleeved on the bottom of the sampling disk 51, and the bottom of the rotating disk 53 is attached to the top of the support column 11. A rotating rod 54 is installed on one side of the rotating disk 53, and the rotating rod 54 is adapted to the rotating shaft seat 12.

[0030] After the soil sample after mixing is loaded into the sample dish in the four-part component 5, the mixing and equal division of the sample are basically completed. It is necessary to remove the equally divided sample from the device. At this time, the rotating disk 53 is rotated along the axis of the rotating rod 54 by using the rotating rod 54 adapted to the rotating shaft seat 12. The rotating disk 53 will drive the sampling tray 51 loaded with the soil sample to rotate out from the bottom of the mixing bin 42, facilitating the operator to easily take out the sampling tray 51 from the device for further operations.

[0031] As Figures 1-7 shown, the mixing component 4 includes a vortex mixer 41. The vortex mixer 41 is installed on the driving frame 3 and is used to provide the drive for the mixing component 4. A mixing bin 42 is installed at the bottom of the vortex mixer 41. The mixing bin 42 is used to load the soil sample to be prepared. A bin door 46 is hinged on the mixing bin 42. The bin door 46 and the mixing bin 42 form an opening and closing structure through a hinge.

[0032] The rotating structure of the bin door 46 facilitates loading the soil sample to be prepared into the mixing bin 42 from the bin door 46. After the soil sample to be prepared enters the mixing bin 42, close the bin door 46, and then turn on the vortex mixer 41. The vortex mixer 41 oscillates and shakes the mixing bin 42 to complete the vortex mixing of the soil sample inside. The working principle of the vortex mixer 41 is mainly based on the eddy current effect generated by high-speed rotation to achieve the uniform mixing of the sample. The vortex mixer 41 drives the mixing head to rotate at high speed through a built-in motor and a transmission. This high-speed rotation can form a strong eddy current. Under the action of the eddy current, the sample is fully dispersed and mixed. The main action modes of the vortex mixer 41 are fixation, oscillation, and mixing treatment.

[0033] As Figures 1-6 shown, a positioning ring 21 is provided around the top of the fixing frame 2. Vibration support rods 43 are evenly distributed around the mixing bin 42. A buffer spring 44 is connected to the bottom of the vibration support rod 43. The vibration support rod 43 is connected to the positioning ring 21 through the buffer spring 44.

[0034] The mixing bin 42 forms an elastic structure with the vibration support rod 43 and the buffer spring 44 through the positioning ring 21. When the mixing bin 42 is affected by the vortex mixer 41, the mixing bin 42 will passively perform actions such as oscillation, shaking, and rotation. The vibration support rod 43 and the buffer spring 44 can protect the mixing bin 42 to complete the above operations within a limited range, ensure that the mixing bin 42 is not damaged, and at the same time provide a stable reset structure to ensure that after the mixing operation is successfully carried out, the mixing bin 42 can return to its initial position, facilitating the later unloading of the soil sample inside the mixing bin 42.

[0035] As Figure 4 、 Figure 7 and Figure 8As shown, a bottom sealing device 45 is provided at the bottom of the mixing bin 42 for ensuring that the soil sample inside the mixing bin 42 does not leak during the mixing operation. The bottom sealing device 45 includes two symmetrical semicircular bottom plates 451. The semicircular bottom plates 451 form a rotating structure with the mixing bin 42 through an axis. A shaft gear 452 is installed at one end of the axis of the semicircular bottom plates 451, and the shaft gears 452 at one end of the axis of the two semicircular bottom plates 451 are meshed. The bottom sealing device 45 also includes a servo motor 453. A driving gear 454 is installed at the output shaft end of the servo motor 453. The driving gear 454 is meshed with one of the axis gears 452.

[0036] When the mixing chamber 42 is driven by the vortex mixer 41 to vibrate and achieve the mixing operation, the bottom sealing device 45 is in a closed state to ensure that the soil sample inside it will not leak from the bottom of the mixing chamber 42. When the mixing chamber 42 completes the mixing operation, the vortex mixer 41 stops working and the servo motor 453 starts to start. The servo motor 453 drives one of the shaft gears 452 to rotate through the drive gear 454 installed on its output shaft end. When the shaft gear 452 rotates, it also drives the other meshing shaft gear 452 to rotate at the same time, so that the semicircular bottom plate 451 rotates along the central axis of the shaft gear 452, opening the bottom of the mixing chamber 42 and allowing the soil sample to be unloaded from the mixing chamber 42 and enter the sampling tray 51. The device uses the meshing transmission between the gears and the servo motor 453 as a rotation drive to achieve the merging and opening of the two semicircular bottom plates 451.

[0037] like Figure 4 and Figure 5 As shown, a discharge channel 22 is passed through the middle of the fixing frame 2 . The discharge channel 22 is configured as a funnel structure and is used to guide the mixed soil sample into the quadrant assembly 5 .

[0038] The top diameter of the discharge channel 22 is larger than the bottom diameter of the mixing chamber 42, so that the mixing chamber 42 is not affected by the discharge channel 22 during mixing and vibration; the bottom diameter of the discharge channel 22 is consistent with the diameter of the sampling plate 51, so that when the mixing chamber 42 unloads the soil sample through the bottom sealing device 45, it can enter the sampling plate 51 along the funnel-shaped inner wall of the discharge channel 22.

[0039] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
