[0033] like Figure 1 As shown, a collection device for the precise collection of rhizosphere soil from fine-rooted plants is provided. The device includes an upper drive rod 1 and a lower soil-collecting rod 2, wherein the upper drive rod 1 and the lower soil-collecting rod 2 are meshed.
[0034] The upper drive rod 1 includes:
[0035] Upper handle 103; The upper handle 103 is made of metal and is horizontally welded to the top of the upper first vertical bar 101 for easy hand operation.
[0036] The upper first vertical rod 101 is located at the bottom of the upper handle 103; the upper first vertical rod 101 is a cylindrical structure and is made of metal.
[0037] The upper second longitudinal bar 102 is disposed at the bottom of the upper first longitudinal bar 101. Both the upper first longitudinal bar 101 and the upper second longitudinal bar 102 are cylindrical structures, and the diameter of the upper first longitudinal bar 101 is larger than the diameter of the upper second longitudinal bar 102. Figure 1 and 2 The upper second longitudinal rod 102 is fixed to the bottom of the upper first longitudinal rod 101 by welding and is on the same center line as the upper first longitudinal rod 101. In use, the upper second longitudinal rod 102 is sleeved in the lower rod 201 and fits tightly with it to ensure stability during rotation.
[0038] The soil inlet 104 is installed on the upper second longitudinal bar 102, and near the bottom of the upper second longitudinal bar 102; for example Figure 2 and 3 As shown, in this embodiment, the upper second vertical rod 102 has soil-collecting openings 104 on both the front and back sides. When the upper second vertical rod 102 drives the lower rod 201, the soil-collecting efficiency can be improved. At the same time, the soil-collecting opening 104 is designed to be elliptical, with its major axis aligned with the rotation direction of the device, which allows for more effective cutting and collection of soil.
[0039] The plug 106 is located at the bottom of the upper second longitudinal rod 102; as shown Figure 2 and 4As shown, the plug 106 is fixed at the bottom of the upper second longitudinal rod 102 by screwing, which is used to take out the upper driving rod 1 from the lower soil sampling rod 2 after the soil sampling through the inner soil sampling port 104 and the outer soil sampling port 202 is completed, and then the plug 106 is taken out, at this time the soil sample can be easily taken out from the bottom of the upper driving rod 1, in addition, the design of the plug 106 has the function of preventing soil from leaking from the bottom of the upper second longitudinal rod 102 during sampling, which ensures the accuracy and integrity of the sampling.
[0040] The lower soil sampling rod 2 comprises:
[0041] The lower rod 201 is sleeved on the upper second longitudinal rod 102 and cooperates with the upper first longitudinal rod 101, the top of the lower rod 201 is tightly attached to the bottom of the upper first longitudinal rod 101 to ensure the stability of the device. The lower rod 201 is made of metal material, which has good strength and durability and can adapt to various soil environments. The bottom of the lower rod 201 is designed to be sharp, which facilitates insertion into the soil and reduces resistance during insertion.
[0042] The outer soil sampling port 202 is arranged on the lower rod 201 and cooperates with the inner soil sampling port 104 to sample soil. As shown in Figure 2 and 3 In this embodiment, two outer soil sampling ports 202 are arranged on the lower rod 201, which are opposite to each other, and can further improve the soil sampling efficiency when used in cooperation with the two inner soil sampling ports 104. The shape of the outer soil sampling port 202 is also designed as an ellipse, and the long axis direction is consistent with the rotation direction of the device, which ensures that the soil can be smoothly cut and enter the inner soil sampling port 104. In addition, the edge of the outer soil sampling port 202 is provided with a cutting edge (not shown in the figure), which can more effectively cut the soil, reduce the resistance of the soil entering the soil sampling port, and improve the soil sampling efficiency and quality.
[0043] In actual operation, the user can insert the lower rod 201 into the soil beside the plant root system by holding the upper handle 103. Then, by rotating the upper handle 103, the upper driving rod 1 is rotated, and then the lower soil sampling rod 2 is rotated. Due to the cooperative design of the inner soil sampling port 104 and the outer soil sampling port 202, the soil will be cut and enter the inner soil sampling port 104. When enough soil samples are collected, the user can take out the upper driving rod 1 from the lower soil sampling rod 2, and then take out the plug 106, at this time the soil sample can be easily taken out from the bottom of the upper driving rod 1. The collection device for fine collection of fine root rhizosphere soil of the present embodiment has many advantages in use. First, its structure is compact, easy to carry and operate, and suitable for soil sampling work in various outdoor environments. The design of the upper handle makes it easy for the user to hold and rotate, and the sharp design of the lower rod helps to smoothly insert into the soil and reduce resistance.
[0044] Secondly, the elliptical structure of the soil taking inner port and the soil taking outer port of the collecting device and the design of the same direction of the long axis make the soil be cut more smoothly and enter the soil taking inner port, the collected soil sample is more refined, and the soil taking efficiency and quality are improved.
[0045] As an optional embodiment of the utility model, optionally, the device further comprises a lower driving rod 204, and the lower driving rod 204 is adjustably arranged on the lower rod 201.
[0046] As shown in Figure 2 and 3 , in the embodiment, the top of the lower rod 201 is provided with a threaded structure, and the lower driving rod 204 is vertically installed at the position of the lower driving rod 204 through the top by the threaded structure, and in use, the position of the lower driving rod 204 on the lower rod 201 can also be adjusted according to actual needs, so as to further adjust the collection depth and improve the flexibility and accuracy of collection. The design of the lower driving rod 204 enables the user to easily adjust the collection depth without pulling out the entire collecting device, which is particularly convenient for researches that need to collect soil samples of different depths.
[0047] As an optional embodiment of the utility model, optionally, the lower rod 201 is provided with a scale line 203.
[0048] As shown in Figure 3 , the lower rod 201 is provided with a scale line 203, and the scale line 203 is arranged to facilitate the user to accurately control the depth of collected soil and ensure that the collected soil sample meets the research requirements. The user can observe the scale line 203 to accurately adjust the insertion depth of the lower rod 201, so as to realize accurate collection of soil samples of different depths. This design greatly improves the flexibility and practicality of collection, so that the user can easily adjust the collection depth according to different research requirements.
[0049] As an optional embodiment of the utility model, optionally, the bottom of the upper first longitudinal rod 101 is provided with at least two protrusions 105, one of which is on the same vertical line with the soil taking inner port 104, and the top of the lower rod 201 is provided with at least two grooves 205 matched with the protrusions 105.
[0050] As shown in Figure 1 and 2In the embodiment, the bottom of the upper first longitudinal rod 101 is integrally formed with two protrusions 105 by casting, and the two protrusions 105 are symmetrically distributed about the center line of the upper first longitudinal rod 101. The design of the two protrusions 105 not only enhances the connection stability of the upper driving rod 1 and the lower soil taking rod 2, but also makes the rotation of the two more smooth, avoiding the problem of incomplete soil collection or low collection efficiency caused by unstable rotation.
[0051] One of the protrusions 105 is on the same vertical line as the soil taking inner opening 104, so that after the upper driving rod 1 is installed on the lower soil taking rod 2, the protrusion 105 cooperates with the groove 205, so that the soil taking inner opening 104 and the soil taking outer opening 202 are not coincident, and the soil taking inner opening 104 and the soil taking outer opening 202 are misaligned, avoiding the soil from entering the soil taking opening during the insertion of the device into the soil, affecting the collection effect. When the lower rod 201 is inserted into the target depth of the soil, the user can lift the upper driving rod 1 upward by a certain distance, at which time the protrusion 105 is disengaged from the groove 205, and the user continues to rotate the upper handle 103 to drive the upper driving rod 1 to rotate, thereby driving the upper second longitudinal rod 102 to rotate, so that the soil taking inner opening 104 and the soil taking outer opening 202 are coincident, and then the upper driving rod 1 is engaged with the lower soil taking rod 2, at which time the upper driving rod 1 is rotated to accurately take soil by the soil taking inner opening 104 and the soil taking outer opening 202.
[0052] As an optional embodiment of the utility model, the center point of the soil taking inner opening 104 and the center point of the soil taking outer opening 202 are on the same horizontal line, which is beneficial to the soil entering the soil taking inner opening 104 from the soil taking outer opening 202 more smoothly, improving the collection efficiency.
[0053] As an optional embodiment of the utility model, the soil taking inner opening 104 and the soil taking outer opening 202 are elliptical structures, and the major axis directions of the soil taking inner opening 104 and the soil taking outer opening 202 are consistent, which makes the soil be cut more smoothly and enter the soil taking inner opening 104 during the collection process. The design of the elliptical structure and the consistent major axis direction can also reduce the resistance of the soil entering the soil taking opening, making the collection process more smooth and efficient. In actual operation, the user only needs to insert the lower rod into the soil at the target depth, and then rotate the upper handle to easily complete the collection of the soil.
[0054] As an optional embodiment of the utility model, the edge of the soil taking outer opening 202 is provided with a cutting edge, which can more effectively cut the soil, especially when encountering hard soil, the cutting edge can reduce the resistance of the soil entering the soil taking opening, improving the soil taking efficiency.
[0055] As an optional embodiment of the utility model, optionally, the outer diameter of the upper first longitudinal rod 101 is equal to the outer diameter of the lower rod 201, the outer diameter of the upper second longitudinal rod 102 is equal to the inner diameter of the lower rod 201, the lower rod 201 can be sleeved on the second longitudinal rod 102, such design not only enhances the stability of the device, but also makes the upper driving rod 101 and the lower soil taking rod 201 more closely cooperate when rotating, avoids the problem of low collection efficiency or soil leakage caused by loosening. In addition, the close cooperation between the upper second longitudinal rod and the lower rod can also effectively prevent soil from leaking from the gap between the two during collection, further ensuring the accuracy and integrity of collection.
[0056] As an optional embodiment of the utility model, optionally, the lower driving rod 204 is provided with an anti-skid sleeve made of rubber material, which has good elasticity and friction force, so that the user can hold more stably when operating the lower driving rod 204, avoiding the problem of inaccurate collection depth or device falling off caused by hand sliding. The design of the anti-skid sleeve also improves the comfort of the user during use, so that long-time operation will not feel tired.
[0057] As an optional embodiment of the utility model, optionally, the surface of the upper handle 103 is provided with anti-skid lines, which are designed with concave-convex design to increase the friction between the hand and the upper handle 103, so that the user can hold more stably when rotating the upper handle 103, avoiding the problem of collection operation failure or device falling off caused by hand sliding. The design of the anti-skid lines not only improves the safety of operation, but also enables the user to control the collection device more easily and accurately during use, further improving the collection efficiency and accuracy.
[0058] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, the scope of the utility model is defined by the claims and its equivalents.
