Description

Technical Field

[0001] This utility model belongs to the field of plant root sampling devices, and relates to a deep-rooted plant root stratification sampling device. Background Technology

[0002] The root systems of deep-rooted plants are highly sensitive to changes in the environment. By stratifying the sampling, we can observe the growth patterns of roots at different soil depths in a timely manner, and at the same time, we can study the impact of soil composition on the root system.

[0003] Existing stratified sampling devices often fail to accurately collect soil and root samples with intact surfaces. Chinese patent CN205785901U discloses a root soil sampler, including a sampling tube, a support assembly, and a handheld crossbar. The support assembly is connected to the sampling tube, and the handheld crossbar is parallel to the support assembly. The sampling tube has at least one tooth. While this sampler improves efficiency, it does not accurately cut the lower surface of the soil and root samples after sampling, resulting in uneven lower surfaces. Chinese patent CN202974700U discloses a plant root sampler, including a sampling assembly and a handle assembly. The sampling assembly includes a sampling tube with one closed end and an observation window on its wall. The handle assembly includes a handheld crossbar and a connecting rod, with the crossbar connected to the closed end of the sampling tube via the connecting rod. Although this device includes an observation window for observing the root soil, it lacks a component for cutting the lower surface.

[0004] Because existing technologies do not extract complete root and soil structures, which is not conducive to accurate analysis of plant roots and soil, a device is needed that can extract soil and root samples completely. Utility Model Content

[0024] The pressure bar 1 is a key component connecting the handle 2 and the sampling box, and can transmit the applied external force to the sampling box. The pressure bar 1 is a hollow pipe, vertically arranged, having a top end and a bottom end. The two handles 2 are symmetrically fixed to the top end of the pressure bar 1, and the end of the handle 2 is welded with a ball, so that the operator can easily hold and apply force while maintaining the stability of the device. The bottom end of the pressure bar 1 is connected to the sampling box.

Two through holes are installed on the top plate 5, and a slot is formed at the lower part of one of the side plates 6. The slot is strip-shaped and horizontally arranged, with a length comparable to that of the side plate 6. The insert cutting plate 8 can be inserted into the slot. A limit frame 7 is fixed around the slot on the outer wall of the side plate 6, with a width of 1-2 cm, which can ensure that the position of the insert cutting plate 8 remains horizontal, thereby horizontally cutting the soil and root system samples, and keeping the lower surface of the soil and root system samples flat.

[0026] As Figure 3 The soil removing assembly is used for removing the soil and root system samples in the sampling box, comprising two connecting rods 4, a push plate 9 and a sliding sleeve 3. The sliding sleeve 3 is sleeved on the pressure bar 1 and can move up and down along the pressure bar 1. Two connecting rods 4 are symmetrically fixed to the two ends of the sliding sleeve 3 by bolts, and the two connecting rods 4 pass through the two through holes of the top plate 5 and are connected to a push plate 9 at the bottom end. The soil removing assembly can move up and down as the soil enters.
