Description

Technical Field

[0001] This utility model belongs to the field of agronomic planting technology, specifically relating to a soil sampling device. Background Technology

[0002] During agronomic planting, it is necessary to sample the soil at multiple points in the planting area to comprehensively judge and analyze information such as soil nutrient composition, so as to supplement the soil with different fertilizers for later planting.

[0003] Currently, most soil sampling devices used in agronomic planting are ring samplers. This involves pressing the ring sampler down into the soil layer at the sampling point and then pulling it up to extract a cylindrical soil sample. The handle of the current ring sampler is located directly above the ring sampler. During sampling, the ring sampler is pushed vertically down to enter the soil layer by pressing the handle down. This simple method of pressing down and pulling up the ring sampler is difficult to apply when the soil layer is hard or dense, making soil sampling troublesome. Furthermore, it is not easy to keep the ring sampler vertically stable when pressing down. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a soil sampling device that solves the problem that most soil sampling devices currently used in agronomic planting are ring samplers. These devices work by pressing the ring sampler down into the soil layer at the sampling point and then pulling it up to extract a cylindrical soil sample. Currently, the handle of the ring sampler is directly above the ring sampler. During sampling, the ring sampler is pushed vertically down to enter the soil layer. This simple vertical pressing and pulling of the ring sampler is difficult to achieve when the soil layer is hard or dense, making soil sampling cumbersome. Furthermore, it is not easy to maintain the vertical stability of the ring sampler during pressing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a soil sampling device, comprising a crossbar, uprights symmetrically arranged on the lower side of the crossbar, a base rod at the lower end of each upright, a short rod in the middle of the side of the crossbar away from the base rod, a fixing block fixedly arranged at the upper end of the short rod away from the crossbar, a rotating block rotatably arranged on the upper side of the fixing block, and fixing rods symmetrically arranged on the upper side of the rotating block. The fixing rods are arranged on the upper side of the base rods, an end block in the end of the fixing rod away from the rotating block, a handle rod in the middle of the side of the end block away from the fixing rod, a collar slidably sleeved in the middle of each fixing rod, a knife handle rotatably arranged on the side of the collars close to each other, a ring cutter threaded at the lower end of the knife handle, an opening at the lower side of the ring cutter, a connecting block in the side of the crossbar close to the knife handle, a limiting cylinder in the end of the connecting block away from the crossbar, and the knife handle being inserted into the limiting cylinder.

The ring cutter is kept stable and vertical by the limiting cylinder and the support rod. By pressing down the handle rod to press down the ring cutter, the lever principle is adopted. The handle rod is made of a relatively long steel pipe, which makes it easier to press down and facilitates soil sampling. Compared with current ring cutter sampling methods, which require not only force to press down but also to maintain the vertical stability of the ring cutter, this device is more convenient, faster, and less labor-intensive, thus helping to improve the efficiency of soil sampling.

[0007] In order to adjust the height of this device;

[0008] As a further improvement to the above technical solution: an extension rod is inserted into the lower side of the upright, the lower end of the extension rod is fixedly connected to the base rod, and a bolt is threaded on the lower side of the upright, the bolt passing through the upright and contacting the extension rod.

[0009] The beneficial effects of this improvement are: the extension rod can be lowered and then the bolts tightened to fix it, which makes it easy to adjust the height of the device and make it suitable for ring cutters of different lengths.

[0010] To increase the comfort of holding the handlebar;

[0011] As a further improvement to the above technical solution: a soft rubber sleeve is provided on the outer side of the handle.

[0012] The beneficial effects of this improvement are: the addition of a soft rubber sleeve increases the comfort of gripping the handle.

[0015] The beneficial effect of this improvement is that it allows the user to step on the pedal during sampling, keeping the device in stable contact with the ground.

[0016] To facilitate quick visualization of the soil sample's cross-sectional structure;

[0017] As a further improvement to the above technical solution: a groove is provided on the lower side of one side of the ring cutter.

[0018] The beneficial effects of this improvement are: by setting a slot, the cross-sectional structure of the soil sample can be quickly observed through the slot when the ring cutter is removed.

[0019] To facilitate control of the sampling depth of the ring cutter;

[0020] As a further improvement to the above technical solution: the side of the knife handle is provided with scale lines.

[0021] The beneficial effect of this improvement is that setting scale lines makes it easier to control the sampling depth of the ring cutter.

[0022] In order to push the soil sample out of the ring cutter;

[0023] As a further improvement to the above technical solution: the upper end of the tool holder is provided with a plug rod, the upper end of the plug rod is provided with a handle, and the lower end of the plug rod is inserted into a push plate provided inside the ring cutter.

[0024] The beneficial effects of this improvement are: by setting up an insertion rod, pushing the insertion rod down with the handle, the insertion rod pushes down the push plate, making it easier to push the soil sample out of the ring cutter after sampling is completed.
