[0002] Corn is widely distributed throughout China and is one of the country's important food, feed, and industrial crops, ranking among the top in terms of planting area and yield. Therefore, research on corn root systems is of paramount importance. In the process of corn root system research, it is necessary to frequently sample the soil to obtain information on the relationship between corn root growth and soil characteristics. However, traditional sampling methods are prone to damaging the root structure, affecting the accuracy of the research and having low practicality.

At the same time, the design of the sampling plate and sampling groove facilitates soil sampling. It is simple and convenient to use and has strong practicality.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a soil sampler for maize root research, comprising a base, a tray, a support frame, a culture box, a sampling plate, a sliding baffle, a rotating shaft, a limiting groove, and a limiting block. The support frame is fixedly installed on the upper surface of the base, the culture box is rotatably arranged on the inner side of the support frame, the sampling plate is arranged on the rear end face of the culture box, the sliding baffle is arranged on the rear side of the sampling plate, the rotating shaft is symmetrically arranged on the left and right ends of the culture box, the rotating shaft has a limiting groove on its annular side, the limiting block is arranged on the inner side of the support frame, and the tray is placed below the culture box.

[0005] Furthermore, the support frame has a rotating connection groove inside, and the culture box is rotatably connected to the support frame through a rotating shaft and the rotating connection groove.

[0006] Furthermore, the inner side of the support frame is provided with a slot, and several sets of slots of the same size are provided, and the limiting block slides tightly along the inner wall of the slot.

Because it adds an observation plate, a rotating shaft, a sampling plate, a sliding baffle, and a sampling groove, the user tilts the culture box so that the roots of the corn seeds grow to the observation plate under the action of gravity and grow downward along the observation plate. This allows the user to clearly observe the growth status of the roots in the soil. When soil sampling is required, the user increases the tilt angle of the culture box so that the sampling plate and the sliding baffle are tilted upward. Then, the sliding baffle is slid open to expose the sampling plate and the block. The block at the corresponding position is then removed to expose the sampling groove, and the soil at that position can be taken out through the sampling groove. This avoids the damage to the corn roots caused by traditional sampling methods. Attached Figure Description

Detailed Implementation

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figures 1-7 This utility model provides a technical solution: a soil sampler for maize root research, including a base 1, a tray 2, a support frame 3, a culture box 4, a sampling plate 5, a sliding baffle 6, a rotating shaft 7, a limiting groove 8, and a limiting block 9. The support frame 3 is fixedly installed on the upper surface of the base 1. The culture box 4 is rotatably arranged on the inner side of the support frame 3. The sampling plate 5 is arranged on the rear end face of the culture box 4. The sliding baffle 6 is arranged on the rear side of the sampling plate 5. The rotating shaft 7 is symmetrically arranged on the left and right ends of the culture box 4. The rotating shaft 7 has a limiting groove 8 on its annular side. The limiting block 9 is arranged on the inner side of the support frame 3. The tray 2 is placed below the culture box 4. This design solves the problem of inconvenient soil sampling in the original maize root research process.

[0017] As the first embodiment of this utility model: a rotating connecting groove 32 is provided inside the support frame 3. The culture box 4 is rotatably connected to the support frame 3 through the rotating shaft 7 and the rotating connecting groove 32. This design facilitates the adjustment of the angle of the culture box 4. A hollow groove 31 is provided inside the support frame 3. Several sets of hollow grooves 31 are provided with the same specifications. The limiting block 9 slides tightly along the inner wall of the hollow groove 31. The hollow groove 31 provides the necessary moving space for the retraction of the limiting block 9. A fixed slide rod 92 is provided inside the hollow groove 31. A connecting slide groove 91 is provided inside the limiting block 9. The limiting block 9 is slidably connected to the fixed slide rod 92 through the connecting slide groove 91. The design of the fixed slide rod 92 makes the movement of the limiting block 9 more stable. Several sets of limiting slots 8 are provided at equal intervals. The limiting slots 8 and the limiting blocks 9 engage with each other. The design of the limiting blocks 9 and the limiting slots 8 facilitates the limiting of the angle of the rotating shaft 7. A compression spring 93 is fitted on the outer side of the fixed slide rod 92. The two ends of the compression spring 93 abut against the surface of the limiting block 9 and the inner wall of the slot 31, respectively. The compression spring 93 provides elastic force so that the limiting block 9 and the limiting slot 8 are engaged. A positioning groove 62 is provided on the rear side of the sampling plate 5. The sliding baffle 6 is slidably connected to the culture box 4 through the positioning groove 62. The rear end face of the sliding baffle 6 is provided with anti-slip ridges 61. The sliding baffle 6 can slide along the inner side of the positioning groove 62. Several sets of sampling slots 51 are evenly spaced on the rear end face of the sampling plate 5. A blocking block 52 is engaged inside the sampling slot 51. The sampling slot 51 facilitates soil sampling from various places. An observation plate 41 is provided on the front end face of the culture box 4. The observation plate 41 is made of quartz glass. A drainage groove 42 is provided on the lower end face of the culture box 4. The design of the observation plate 41 facilitates the user to observe the growth of the root system.

[0018] As a second embodiment of this utility model: The user fills the cultivation box 4 with soil and places the corn seeds inside. The user then tilts the cultivation box 4. Due to the design of the limiting block 9 and the limiting groove 8, the cultivation box 4 and the rotating shaft 7 can only rotate when an external force overcomes the elastic force of the compression spring 93. Without external force, the limiting block 9 keeps the rotating shaft 7 in place, thus fixing the cultivation box 4 at a certain angle. Because the cultivation box 4 is tilted, the roots of the corn seeds will grow to the observation plate 41 first under the influence of gravity. Once the roots reach the observation plate 41, the user can reduce the tilt angle of the cultivation box 4, allowing the corn seed roots to grow downwards along the observation plate 41, thus enabling the user to clearly observe the roots. The quartz glass plate has good corrosion resistance, which can prevent chemicals in the soil from damaging the observation plate 41. The design of the drainage groove 42 helps to drain excess water and keep the inside of the culture box 4 dry, which is conducive to the healthy growth of the roots. When soil sampling is required, the user increases the tilt angle of the culture box 4 so that the sampling plate 5 and the sliding baffle 6 are tilted upward. Then, the sliding baffle 6 is slid open to expose the sampling plate 5 and the block 52. Then, the block 52 in the corresponding position is removed to expose the sampling groove 51. The soil at that position can be taken out through the sampling groove 51, avoiding the damage to the corn roots caused by traditional sampling methods. After sampling, the block 52 is reinstalled and the sliding baffle 6 is closed to prevent the soil from falling.
