Description

Technical Field

[0001] This utility model relates to the technical field of soil drying equipment, specifically a drying device for soil testing. Background Technology

[0002] Soil environmental monitoring refers to determining environmental quality and its changing trends by measuring representative values ​​of factors affecting soil environmental quality. Soil monitoring, as we usually refer to it, generally includes technical aspects such as sampling, sample preparation, analytical methods, result characterization, data statistics, and quality evaluation. Before soil testing, the sampled soil needs to be dried.

[0003] A Chinese patent (publication number: CN219495893U) discloses a soil drying device for soil testing, including a drying chamber. A fixed frame is fixedly connected to the upper surface of the drying chamber. A sliding plate is provided inside the fixed frame. A drive motor is fixedly installed on the upper surface of the sliding plate. An electric push rod is fixedly installed at the top of the fixed frame. The output end of the electric push rod is fixedly connected to the top of the drive motor. A drying dish is provided inside the drying chamber. A stirring shaft is provided inside the drying dish. A stirring blade is fixedly connected to the bottom end of the stirring shaft. An opening is provided on the upper surface of the drying chamber. By installing a magnetic control component inside the drying chamber, the magnetic control component and the controller work together to microwave heat the inside of the drying chamber. At the same time, during the drying process, the drive motor drives the stirring blade to stir the soil, thereby making the soil evenly heated and ensuring the uniformity of drying.

[0004] The aforementioned equipment uses stirring blades to agitate the soil during operation and works in conjunction with heating equipment to dry it. However, to improve drying efficiency, the soil often needs to be crushed before agitation and drying. Existing crushing equipment is not convenient for adjusting the crushing efficiency according to soil characteristics. For softer soils, the crushing components may operate at a high, fixed speed. This can lead to over-crushing, resulting in excessively fine soil particles. These excessively fine particles may form dust during drying, causing soil sample loss. For hard, tightly packed soils, such as clay clumps, a fixed and low speed results in insufficient shearing and impact forces from the crushing components. This prevents the soil clumps from being effectively broken up. Utility Model Content

This effectively addresses soils of different hardness, ensures crushing effect, and improves drying efficiency. By coordinating crushing and drying, crushing first and then drying, the soil is ensured to be heated evenly.

[0020] 2. The rotation state of the turntable can be adjusted or locked by operating the transmission bolts. The limit block can be placed against the appropriate position of the transmission block to effectively limit the rotation of the turntable, ensuring the stability of the arc-shaped part after adjustment and avoiding unexpected changes that may affect the transmission ratio and the operation of the crushing parts.

[0028] 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.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a soil drying device, comprising a drying cylinder 1 and a stirring rack 2 rotatably disposed within the drying cylinder 1, including...

[0030] The crushing component 302 is rotatably connected inside the drying cylinder 1 and is used to crush soil particles;

[0031] Mounting frame 303 is rotatably connected to the top of drying cylinder 1. Rotary disk 304 is rotatably connected inside mounting frame 303. Multiple first wedge-shaped contact blocks 305 are connected to the rotating disk 304 in a circumferential array with equal spacing.

[0032] The second wedge-shaped abutment block 306 is slidably connected to the mounting frame 303, and its position corresponds to that of the first wedge-shaped abutment block 305. When the first wedge-shaped abutment block 305 rotates counterclockwise around its axis, it drives the second wedge-shaped abutment block 306 to slide horizontally away from the turntable 304. The other end of the second wedge-shaped abutment block 306 is connected to an arc-shaped component 307. Multiple arc-shaped components 307 are used together to form a circular transmission component.

[0033] A servo motor 308 is mounted on the drying cylinder 1 to drive the mounting frame 303 to rotate. A synchronous pulley 309 is connected to the drive shaft of the servo motor 308, and a synchronous belt 310 is connected between the synchronous pulley 309 and the circular transmission component.

[0034] It should be noted that the synchronous belt 310 is made of elastic material, and the drying cylinder 1 is equipped with a heating wire in a spiral shape to provide heat for drying the soil inside the drying cylinder 1.

[0035] In practice, starting the servo motor 308 can drive the synchronous pulley 309 to rotate. Since the synchronous pulley 309 and the circular transmission component composed of multiple arc-shaped parts 307 are connected by a synchronous belt 310, the circular transmission component will rotate accordingly. At this time, the crushing component 302 can rotate synchronously to crush the soil. Meanwhile, the operator can rotate the turntable 304 as needed to make the turntable 304 abut against the second wedge-shaped contact block 306, expand the inner diameter of the circular transmission component, and increase the transmission ratio between it and the synchronous pulley 309 to increase or decrease the crushing speed of the crushing component 302, thereby facilitating the crushing and drying of soils with different hardness.

[0036] See Figure 2 A filter plate 301 is connected inside the drying cylinder 1, and the crushed part 302 is located above the filter plate 301.

[0037] In practice, the filter plate 301 facilitates soil filtration and works in conjunction with the crusher 302 to crush soil particles.

[0038] See Figure 5The second wedge-shaped contact block 306 is connected to two symmetrical connecting plates 10, and a return spring 9 is connected to the connecting plate 10. The other end of the return spring 9 is connected to the inner wall of the mounting frame 303.

[0039] In practice, the reset spring 9 can be used in conjunction with the connecting plate 10 to assist the second wedge-shaped contact block 306 in returning to its original position, so that the second wedge-shaped contact block 306 has a reset effect.

[0040] See Figure 4 The top of the mounting frame 303 is connected to a fixed frame 401, and the top of the turntable 304 is connected to a rotating shaft 402. One end of the rotating shaft 402 extends into the fixed frame 401 and is connected to a transmission block 403. A transmission bolt 405 is threaded onto the fixed frame 401, and the other end of the transmission bolt 405 extends into the fixed frame 401 and is rotatably connected to a limit block 404. The limit block 404 is used to limit the transmission block 403.

[0041] In practice, when it is necessary to adjust or lock the rotation state of the turntable 304, the transmission bolt 405 can be operated. Rotating the transmission bolt 405 causes it to move axially due to its threaded connection to the fixed frame 401. The other end of the transmission bolt 405 extends into the fixed frame 401 and is rotatably connected to a limit block 404. As the transmission bolt 405 moves axially, the limit block 404 also moves accordingly.

[0042] When the limiting block 404 approaches the transmission block 403, it constrains the transmission block 403. If the limiting block 404 is pressed tightly against the transmission block 403 at a suitable position, the rotation of the transmission block 403 can be restricted. Since the transmission block 403 is connected to the rotating shaft 402, and the rotating shaft 402 is connected to the turntable 304, the rotation of the turntable 304 is locked, thereby improving the stability of the arc-shaped component 307 after adjustment.

[0043] refer to Figure 4 One side of the limiting block 404 is connected to a guide rod 5, which is slidably connected within the fixed frame 401.

[0044] In practice, the guide rod 5 can limit and guide the sliding of the limit block 404, further improving the stability of the limit block 404 during the sliding process.

[0045] refer to Figure 3 One end of the rotating shaft 402 extends into the drying cylinder 1 and is connected to an electric telescopic rod 8, which is used to adjust the crushing height of the crushed part 302.

[0046] In practice, the electric telescopic rod 8 is set to adjust the crushing height of the crushing component 302 to adapt to soil particles of different sizes.

[0047] refer to Figure 3 The bottom of the electric telescopic rod 8 is connected to a drive shaft. The crushing component 302 includes a connecting rod 6 and a crushing cylinder 7. The connecting rod 6 is connected to the drive shaft, and the crushing cylinder 7 is rotatably connected to the connecting rod 6. One end of the connecting rod 6 is connected to the drive shaft.

[0048] In practice, the connecting rod 6 is set to make the crushing cylinder 7 rotate synchronously with the drive shaft, and the crushing cylinder 7 is set to make it convenient to crush the soil.

[0049] refer to Figure 4 A mounting bracket is connected to the drying cylinder 1, and the servo motor 308 is connected to the mounting bracket.

[0050] In practice, this setup facilitates the installation of the servo motor 308.

[0051] Working principle: Starting the servo motor 308 can drive the synchronous pulley 309 to rotate. Since the synchronous pulley 309 and the circular transmission component composed of multiple arc-shaped parts 307 are connected by the synchronous belt 310, the circular transmission component will rotate accordingly. At this time, the crushing part 302 can rotate synchronously to crush the soil. Meanwhile, the operator can rotate the turntable 304 as needed to make the turntable 304 abut against the second wedge-shaped contact block 306, expand the inner diameter of the circular transmission component, and increase the transmission ratio between it and the synchronous pulley 309, thereby increasing or decreasing the crushing speed of the crushing part 302, so as to facilitate the crushing and drying of soil with different hardness.

[0052] When it is necessary to adjust or lock the rotation state of the turntable 304, the transmission bolt 405 can be operated. Rotating the transmission bolt 405 causes it to move axially due to its threaded connection to the fixed frame 401. The other end of the transmission bolt 405 extends into the fixed frame 401 and is rotatably connected to a limit block 404. As the transmission bolt 405 moves axially, the limit block 404 also moves accordingly.

[0053] When the limiting block 404 approaches the transmission block 403, it constrains the transmission block 403. If the limiting block 404 is pressed tightly against the transmission block 403 at a suitable position, the rotation of the transmission block 403 can be restricted. Since the transmission block 403 is connected to the rotating shaft 402, and the rotating shaft 402 is connected to the turntable 304, the rotation of the turntable 304 is locked, thereby improving the stability of the arc-shaped component 307 after adjustment.
