Description

Technical Field

[0001] This application relates to the field of agricultural production, and particularly relates to an agricultural sampling device. Background Art

[0002] The purposes of agricultural sampling are diverse. For example, to evaluate the fertility status of the soil, determine the occurrence degree and distribution range of pests and diseases, and detect the pesticide residues in fruits. Agricultural sampling also has requirements for the representativeness and accuracy of samples.

[0003] When taking soil samples, multi-point and multi-depth sampling are required. Although the soil in cultivated land is soft, the deep soil still needs to dig through the surface soil or use drill-like tools to achieve accurate sampling, which is troublesome. Utility Model Content

[0004] This application provides an agricultural sampling device for solving the problem of troublesome soil sampling in cultivated land.

[0005] This application provides an agricultural sampling device, including a main body, extension plates, sliding plates, and a pointed cone. The main body is cylindrical, and a plurality of sampling grooves are provided on one side wall of the main body, and the plurality of sampling grooves are spaced along the axial direction of the main body. Two extension plates are provided, and the extension plates are arranged on the outer wall surface of the main body. The extension plates are fixedly connected to the main body. The two extension plates are located on both sides of the plurality of sampling grooves and extend along the axial direction of the main body. Sliding grooves are opened on the opposite side walls of the two extension plates, and the sliding grooves extend along the extension direction of the extension plates. The sliding plates are arranged as arc-shaped plates, and sliding blocks are extended on the two side walls of the sliding plates. The two sliding blocks correspond to the two sliding grooves one by one. The sliding blocks extend into the corresponding sliding grooves to make the sliding plates slidably connected to the extension plates. The pointed cone is arranged at one end of the main body, and the pointed cone is coaxially arranged with and fixedly connected to the main body.

[0006] In this application, the main body and the pointed cone can be inserted into the ground. At this time, the extension plates and the sliding plates can block the sampling grooves to prevent soil from falling in. When the main body is inserted into the soil to a certain depth, the sliding plates can be slid along the sliding grooves, and the edges of the sliding plates can slide over the sampling grooves to open the sampling grooves. At this time, the main body can be tilted or rotated to make the sampling grooves enter the soil at a specified depth. Then, the sliding plates can be slid to cover the sampling grooves and the main body can be taken out, which is convenient for sampling.

[0007] This solution can facilitate more convenient and accurate sampling of the specified depth in cultivated land, reduce the number of tools used, improve the sampling efficiency, and help evaluate the fertility status of the soil.

[0008] In some embodiments of this application, along the axial direction of the main body, the gaps between adjacent two sampling grooves are equal. The equal gaps between the sampling grooves contribute to sampling the soil at equal depth intervals, and then facilitate drawing corresponding curve graphs according to the evaluation status of the soil at different depths to achieve better data statistics.

[0009] In some embodiments of the present application, the sliding plate further includes an abutting plate. A gap is formed between the sliding plate and the main body. The abutting plate is disposed at one end of the sliding plate close to the tapered body and extends along the direction of the sliding plate towards the main body. The abutting plate abuts against the sliding plate and is slidably connected to the outer wall surface of the main body.

[0010] The gap between the sliding plate and the main body can reduce the sliding resistance of the sliding plate and make the sliding more convenient. The abutting plate can prevent soil from entering the sampling groove along the gap between the sliding plate and the main body when the main body penetrates into the ground, thereby protecting the sampled sample and ensuring the accuracy of the sampled sample.

[0011] In some embodiments of the present application, one side wall of the sliding plate abuts against one side wall of the extension plate. At this time, the sealing degree between the sliding plate and the extension plate can be further ensured, protecting the sampling groove and preventing non-sampled samples from mixing into the corresponding sampling groove.

[0012] In some embodiments of the present application, the sliding plate further includes a handle, and the handle is disposed on the wall surface of the sliding plate away from the main body. The handle can make the sliding of the sliding plate more convenient.

[0013] In some embodiments of the present application, the handle is disposed on the part of the sliding plate away from the tapered body. When the handle is disposed on the part of the sliding plate away from the tapered body, the handle can be closer to the user, making it easier for the user to operate.

[0014] In some embodiments of the present application, the agricultural sampling device further includes a handrail, and the handrail includes a connecting column and a disc. The connecting column is fixedly connected to the side wall of the main body, and the disc is disposed on one side of the main body away from the tapered body and is fixedly connected to the connecting column. The handrail facilitates the user to insert the main body into the ground or to tilt and rotate the main body for sampling.

[0015] In some embodiments of the present application, a plurality of connecting columns are provided, and the plurality of connecting columns are spaced apart around the axis of the main body. The plurality of connecting columns can make the connection between the disc and the main body more stable.

[0016] In some embodiments of the present application, along the axial direction of the main body, the chute penetrates through one end face of the extension plate away from the tapered body so that the sliding plate can slide out of the extension plate. The chute penetrating through the extension plate can facilitate the sliding plate to slide out and be removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The purposes of agricultural sampling are diverse, such as evaluating the fertility status of the soil, determining the occurrence degree and distribution range of pests and diseases, and the pesticide residues in fruits. Agricultural sampling also has requirements for the representativeness and accuracy of samples.

[0027] When taking soil samples, it is necessary to take samples at multiple points and multiple depths. Although the soil in agricultural land is soft, the deep soil still needs to dig through the surface soil or use drill-like tools to achieve accurate sampling, which is troublesome.

[0028] For this reason, please refer to Figure 1 , the present application provides an agricultural sampling device, including a main body 1, an extension plate 2, a sliding plate 3, and a pointed cone 4.

[0030] Please refer to Figure 1 , two extension plates 2 are provided. The extension plates 2 are arranged on the outer wall surface of the main body 1, and the extension plates 2 are fixedly connected to the main body 1. The two extension plates 2 are located on both sides of the plurality of sampling grooves 11 and extend along the axial direction of the main body 1. Sliding grooves 21 are provided on the opposite side walls of the two extension plates 2, and the sliding grooves 21 extend along the extension direction of the extension plates 2.

[0031] Please refer to Figure 1 , the extension plate 2 can be made of the same material as the main body 1, both can be made of iron, and the extension plate 2 can be welded to the main body 1 or can also be integrally formed. The included angle between the two extension plates 2 can be 60° to 180°, preferably 120°, to reduce the arc of the extension plate 2, thereby facilitating the sliding of the extension plate 2.

[0032] Please refer to Figure 1, the extending direction of the extension plate 2 can be parallel to the axis direction of the main body 1. At the same time, the two extension plates 2 can be exactly the same, or the two extension plates 2 can only be similar. The sliding grooves 21 of the two extension plates 2 can be the same or different; the cross-section of the sliding groove 21 can be polygonal or arc-shaped. In order to facilitate the cleaning of the soil in the sliding groove 21, the sliding groove 21 can be set as an arc shape.

[0033] Please refer to Figure 1 , the sliding plate 3 is set as an arc-shaped plate. Sliders 31 are extendedly provided on the two side walls of the sliding plate 3. The two sliders 31 correspond to the two sliding grooves 21 one by one. The slider 31 extends into the corresponding sliding groove 21 and makes the sliding plate 3 slidably connected to the extension plate 2. The arc-shaped plate can be a metal plate. The slider 31 can be one or more block structures, or can also be a strip structure to form the slider 31. The cross-section of the slider 31 can be correspondingly set with the cross-section of the sliding groove 21.

[0034] Please refer to Figure 1 , the inner arc surface of the sliding plate 3 can correspond to the outer wall surface of the main body 1, so that the sliding plate 3 can fit with the main body 1, and at the same time, the resistance of the sliding plate 3 sliding into the soil can be reduced. The material of the sliding plate 3 can be a metal product or a non-metal product.

[0035] Please refer to Figure 1 , the pointed cone 4 is arranged at one end of the main body 1. The pointed cone 4 is coaxially arranged with the main body 1 and fixedly connected. The pointed cone 4 can have a tip and can form a cone or a pyramid as a whole; the pointed cone 4 and the main body 1 can be integrally formed, welded or thread-connected.

[0036] Please refer to Figure 1 , the main body 1 and the pointed cone 4 in this application can be inserted into the ground. At this time, the extension plate 2 and the sliding plate 3 can block the sampling groove 11 to prevent soil from falling in. When the main body 1 is inserted into the soil to a certain depth, the sliding plate 3 can be slid along the sliding groove 21, and the edge of the sliding plate 3 can be made to slide over the sampling groove 11 to open the sampling groove 11. At this time, the main body 1 can be tilted or rotated to make the soil at a specified depth enter the sampling groove 11, and then the sliding plate 3 can be slid to cover the sampling groove 11 and the main body 1 can be taken out, which is convenient for sampling.

[0037] Please refer to Figure 1 , in some examples, in order to avoid local rusting of the agricultural sampling device, anti-rust treatment can be carried out on the outer surfaces of all parts of the agricultural sampling device. For example, painting or electroplating an anti-rust film can be carried out to achieve the anti-rust effect.
