Technical Field
[0001] This utility model relates to the field of soil testing technology, and in particular to a sample processing device for soil testing. Background Technology
[0002] Soil testing is a technical means of analyzing and measuring the composition, physicochemical properties, and pollutant content of soil using scientific methods to assess soil quality, health status, and suitable uses. Its purposes cover agricultural production, environmental protection, engineering construction, scientific research, and teaching. Testing items include physicochemical properties, pollutant indicators, and biological indicators. Sample collection and preparation specifications must be followed, and methods such as chemical analysis, instrumental analysis, and biological detection must be used. It must be carried out in accordance with relevant domestic and international standards and is widely used in farmland management, contaminated site remediation, and other scenarios. When operating, attention must be paid to sampling accuracy and method selection. Currently, it is developing towards rapid detection, intelligentization, multi-indicator comprehensive evaluation, and big data application.
[0003] Soil testing requires sample drying, necessitating the use of a drying device. However, current drying devices lack adjustable internal space, making them inconvenient for drying different types and sizes of samples, limiting their applicability. Furthermore, samples are often left stationary during drying, preventing uniform contact with the heat source and potentially affecting the drying effect. Therefore, this application proposes a sample processing device for soil testing to meet these requirements. Utility Model Content
[0004] In order to overcome the shortcomings of existing devices that cannot adjust the size of the internal space and that static drying will lead to uneven drying, this utility model provides a sample processing device for soil testing.
[0005] The technical implementation scheme of this utility model is as follows: a sample processing device for soil testing, including a drying box with several sets of heating wires installed on the inner wall, a door installed on one side of the drying box, an installation rod rotatably connected to the center of the top inner wall of the drying box, several sets of trays for placing samples provided on the inner wall of the drying box, a partition adapted to the size of the drying box fixedly connected to the bottom of the tray, a through groove adapted to the size of the installation rod passing through the middle of the partition and the tray, an adjustment component provided at the connection between the partition and the installation rod, a base fixedly connected to the bottom of the drying box, and a driving component provided inside the base.
[0006] Optionally, the adjustment assembly includes a lifting groove, a first lifting block, and a second lifting block. The lifting groove is formed on both sides of the mounting rod, and the first lifting block and the second lifting block are respectively fixedly connected to the inner walls of both sides of the through groove and slidably connected to the lifting groove.
[0007] Optionally, the adjustment assembly further includes a fixing hole, a connecting groove, a socket, and a plug rod. The fixing hole is provided in several sets and extends through the inner wall of the lifting groove. The connecting groove is opened in the inner wall of the through groove and extends through the second lifting block. The socket is opened on the side surface of the first lifting block near the second lifting block. The plug rod is movably connected to the connecting groove and is adapted to the size of the fixing hole and the socket.
[0008] Optionally, the adjustment assembly further includes a slide groove, a slider, and a spring. The slide groove is located at the bottom of the partition and one end is connected to the connecting groove. The slider is fixedly connected to the end of the insertion rod away from the insertion hole and slidably connected to the slide groove. The spring is installed inside the slide groove and its two ends are respectively fixedly connected to the inner wall of the slider away from the insertion rod and the inner wall of the slide groove away from the insertion rod.
[0009] Optionally, the drive assembly includes a cavity, a rotating groove, a rotating shaft, a worm gear, and a worm. The cavity is composed of cylindrical and rectangular shapes and is located inside the base. The rotating groove passes through the inner wall of the top of the cavity and communicates with the drying chamber. The rotating shaft is fixedly connected to the bottom of the mounting rod and rotatably connected to the rotating groove. The bottom of the rotating shaft is rotatably connected to the inner wall of the bottom of the cavity. The worm gear is fixedly connected to the outer periphery of the rotating shaft near the bottom. The worm is installed inside the cavity and meshes with the worm gear.
[0010] Optionally, the drive assembly further includes a motor, drive wheels, and a drive belt. The motor is installed inside the cavity and is located on one side of the worm. Two sets of drive wheels are provided and are respectively fixedly connected to the drive shaft of the motor and one end of the worm. The drive belt is wound around the two sets of drive wheels.
[0011] This utility model has the following advantages:
[0012] 1. This utility model features an adjustment component. A slider moves along the slide groove away from the through groove, compressing a spring and causing the insertion rod to move synchronously. When the insertion rod moves out of the insertion hole and fixing hole, the first and second lifting blocks slide along the lifting groove, causing the partition and tray to rise and fall synchronously. After reaching the appropriate position, the slider is released, the spring rebounds, and the slider moves the insertion rod closer to the through groove. When the insertion rod passes through the fixing hole at the current height and inserts into the insertion hole, the partition and tray are fixed at the current height. This design allows the device to adjust the size of the drying chamber by adjusting the position of the partition and tray, making it suitable for drying samples of different types and specifications.
[0013] 2. This utility model is equipped with a drive assembly. When the motor is started, it drives a set of transmission wheels to rotate through the drive shaft. Since the transmission belt is wrapped around two sets of transmission wheels, the other set of transmission wheels will drive the worm to rotate synchronously with the drive shaft of the motor. Since the worm wheel meshes with the worm, the worm wheel will drive the mounting rod to rotate synchronously through the rotating shaft. This causes the tray to rotate with the sample in the drying oven. This design allows the device to drive the tray to rotate, so that the sample can be in uniform contact with the heat source, effectively ensuring the drying quality. Attached Figure Description

It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in this document are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0020] A soil testing sample processing device includes a drying chamber 1 with several sets of heating wires installed on its inner wall, a door 2 installed on one side of the drying chamber 1, an installation rod 3 rotatably connected to the center of the inner wall of the top of the drying chamber 1, several trays 4 for placing samples are provided on the inner wall of the drying chamber 1, a partition 5 adapted to the size of the drying chamber 1 is fixedly connected to the bottom of the tray 4, a through groove 6 adapted to the size of the installation rod 3 is passed through the middle of both the partition 5 and the tray 4, an adjustment component 7 is provided at the connection between the partition 5 and the installation rod 3, and a base 8 is fixedly connected to the bottom of the drying chamber 1, and a drive component 9 is provided inside the base 8.
[0021] It should be noted that the adjustment component 7 allows the device to adjust the size of the drying chamber by adjusting the position of the partition 5 and the tray 4, thus making it suitable for drying samples of different types and specifications. The drive component 9 allows the device to rotate the tray 4, so that the sample can be in uniform contact with the heat source, effectively ensuring the drying quality.
[0022] like Figure 2 and Figure 3 As shown, the adjustment component 7 includes a lifting groove 71, a first lifting block 72, and a second lifting block 73. The lifting groove 71 is opened on both sides of the mounting rod 3. The first lifting block 72 and the second lifting block 73 are respectively fixedly connected to the inner walls of both sides of the through groove 6 and slidably connected to the lifting groove 71.
[0023] It should be noted that the height of the partition 5 and the tray 4 can be adjusted by sliding the first lifting block 72 and the second lifting block 73 along the lifting groove 71.
[0024] like Figure 2 and Figure 3 As shown, the adjustment component 7 also includes a fixing hole 74, a connecting groove 75, a socket 76, and a plug rod 77. The fixing hole 74 is provided in several sets and extends through the inner wall of the lifting groove 71. The connecting groove 75 is opened in the inner wall of the through groove 6 and extends through the second lifting block 73. The socket 76 is opened on the side surface of the first lifting block 72 near the second lifting block 73. The plug rod 77 is movably connected to the connecting groove 75 and is adapted to the size of the fixing hole 74 and the socket 76.
[0025] It should be noted that the position of the partition 5 can be adjusted by removing the insertion rod 77 from the insertion hole 76 and the fixing hole 74, and the partition 5 can be fixed in the current position by passing the insertion rod 77 through the fixing hole 74 and inserting it into the insertion hole 76.
[0026] like Figure 3 As shown, the adjustment assembly 7 also includes a slide groove 78, a slider 79, and a spring 710. The slide groove 78 is located at the bottom of the partition 5 and one end is connected to the connecting groove 75. The slider 79 is fixedly connected to the end of the insertion rod 77 away from the insertion hole 76 and slidably connected to the slide groove 78. The spring 710 is installed inside the slide groove 78 and its two ends are fixedly connected to the side of the slider 79 away from the insertion rod 77 and the inner wall of the slide groove 78 away from the insertion rod 77, respectively.
[0027] It should be noted that sliding the slider 79 along the slide groove 78 away from the through groove 6 can compress the spring 710 and drive the insertion rod 77 to move synchronously. Releasing the slider 79 will cause the spring 710 to rebound, which will drive the insertion rod 77 to move closer to the through groove 6 via the slider 79.
[0028] like Figure 2 and Figure 4As shown, the drive assembly 9 includes a cavity 91, a rotating groove 92, a rotating shaft 93, a worm gear 94, and a worm 95. The cavity 91 is composed of cylindrical and rectangular parts and is located inside the base 8. The rotating groove 92 passes through the inner wall of the top of the cavity 91 and is connected to the drying chamber 1. The rotating shaft 93 is fixedly connected to the bottom of the mounting rod 3 and rotatably connected to the rotating groove 92. The bottom of the rotating shaft 93 is rotatably connected to the inner wall of the bottom of the cavity 91. The worm gear 94 is fixedly connected to the outer periphery of the rotating shaft 93 near the bottom. The worm 95 is installed inside the cavity 91 and meshes with the worm gear 94.
[0029] It should be noted that rotating the worm gear 95 will drive the worm wheel 94 to rotate, and the worm wheel 94 will drive the mounting rod 3 to rotate synchronously through the rotating shaft 93, thereby enabling the partition plate 5 and the tray 4 to drive the sample to rotate inside the drying oven 1.
[0030] like Figure 4 As shown, the drive assembly 9 also includes a motor 96, a drive wheel 97, and a drive belt 98. The motor 96 is installed inside the cavity 91 and is located on one side of the worm 95. Two sets of drive wheels 97 are provided and are respectively fixedly connected to the drive shaft of the motor 96 and one end of the worm 95. The drive belt 98 is wound around the two sets of drive wheels 97.
[0031] It should be noted that starting the motor 96 will drive a set of transmission wheels 97 to rotate via the drive shaft. Since the transmission belt 98 is wrapped around the two sets of transmission wheels 97, the other set of transmission wheels 97 will drive the worm gear 95 to rotate synchronously with the drive shaft of the motor 96.
[0032] In a specific application scenario, first, open the chamber door 2 and place the sample on top of the tray 4. Then, close the chamber door 2 and start the heating wire and motor 96. The motor 96 will drive a set of transmission wheels 97 to rotate via the drive shaft. Since the transmission belt 98 is wrapped around the two sets of transmission wheels 97, the other set of transmission wheels 97 will drive the worm 95 to rotate synchronously with the drive shaft of the motor 96. Since the worm wheel 94 meshes with the worm 95, the worm wheel 94 will drive the mounting rod 3 to rotate synchronously via the rotating shaft 93. This causes the tray 4 to rotate the sample inside the drying chamber 1, ensuring that the sample can make uniform contact with the heat source. When it is necessary to dry samples of different specifications, the sample is moved along the slide groove 7. Slide slider 79 away from through slot 6 to compress spring 710 and drive insertion rod 77 to move synchronously. When insertion rod 77 moves out of insertion hole 76 and fixing hole 74, slide first lifting block 72 and second lifting block 73 along lifting slot 71 to drive partition 5 and tray 4 to move synchronously up and down. After moving to the appropriate position, release slider 79. Spring 710 rebounds and drives insertion rod 77 to move closer to through slot 6 through slider 79. When insertion rod 77 passes through fixing hole 74 at the current height and inserts into insertion hole 76, partition 5 and tray 4 can be fixed at the current height. At this time, drying work can be carried out on samples of different types and specifications.
