Description

Technical Field

[0001] This utility model belongs to the field of land sampling technology, and in particular to a land sampling device for land management. Background Technology

[0002] Land management personnel need to collect soil samples from different areas during surveys, and then laboratory personnel test the soil based on these samples. Commonly used tools for soil sampling include shovels, spades, drilling rods, and sampling tubes. These tools are used to break up the soil before the samples are collected manually. However, when encountering hard soil, sampling with these tools becomes difficult, requiring the use of specialized sampling devices. Traditional sampling devices, when using a foot pedal, tend to rotate if the ground is firm and smooth, affecting the sampling process.

[0003] A search revealed a Chinese patent document (authorization announcement number CN219573546U) for a land sampling device for land management. The device includes a sampling cylinder, a soil-drilling mechanism for loosening the soil, and a sampling pressing component for soil collection. The sampling pressing component is installed inside the sampling cylinder and can move up and down along the cylinder. The soil-drilling mechanism includes a drive motor and a auger drill bit, with the drive motor mounted on top of the sampling cylinder. This invention facilitates sampling on hard soil and pushes out soil samples from inside the pressing cylinder during collection, preventing excessive soil residue and improving testing quality. It also offers good safety. However, the sampling device described in the patent, when using a foot pedal, is prone to spinning if the soil is firm and smooth, affecting the sampling process. Utility Model Content

[0004] The purpose of this invention is to provide a land sampling device for land management to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a land sampling device for land management, comprising:

[0006] Sampling tube, which contains a land sampling component for land management;

[0007] Two mounting plates are fixedly connected to the outer periphery of the sampling tube and are C-shaped. The inner wall of the mounting plate is rotatably connected to a C-shaped stabilizing plate through a damping shaft. The sides of the stabilizing plate are welded with multiple spikes to improve stability. The sides of the stabilizing plate are also provided with threaded channels, and the threaded channels are threaded to anchor rods.

[0008] The outer periphery of the sampling tube has multiple discharge channels for discharging material during sampling. The inner wall of the discharge channel is rotatably connected to a movable plate, which is fixed to the sampling tube by a latch.

[0009] As a preferred embodiment, the sampling component includes:

[0010] An assembly disc is placed inside the sampling tube;

[0011] Both limiting rods are welded to the outer periphery of the assembly circular plate, and two sliding channels are opened on the outer periphery of the sampling tube for the limiting rods to pass through;

[0012] The forward and reverse motors are mounted on the top of the assembly disc, and the output shafts of the forward and reverse motors pass through the assembly disc and are connected to a rotating rod.

[0013] As a preferred embodiment, a helical blade for sampling is welded to the outer periphery of the rotating rod, and a drill bit is welded to the bottom end of the rotating rod.

[0014] As a preferred embodiment, two limiting arc-shaped plates adapted to the inner cavity of the sampling tube are also welded to the top of the assembly circular plate.

[0015] As a preferred embodiment, two supporting arc-shaped plates are welded to the outer periphery of the sampling tube, and multiple sample storage tubes supported by the supporting arc-shaped plates are provided on the outer periphery of the sampling tube. Two binding ropes are glued to the outer periphery of the sampling tube, which are respectively used to fix the stabilizing plate and the sample storage tubes.

[0016] As a preferred embodiment, one of the supporting arc-shaped plates is rotatably connected to a limiting plate with four limiting sampling components on its outer periphery, and the limiting plate is connected and fixed to another supporting arc-shaped plate by a latch.

[0017] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0018] When using this land management land sampling device, the stabilizing plate is rotated to a horizontal position and stepped on to insert the spikes into the soil. Alternatively, anchor rods can be used to drill into the soil. At this time, the operator stands on the stabilizing plate, turns on the forward and reverse motors, and presses down the limit rod to move it down, thereby causing the drill bit and spiral blades to rotate and move down to sample. Compared with the traditional pedal design, it is more stable, especially for hard and smooth soil, and can ensure stable sampling.

[0019] The land sampling device for land management has an assembly plate that ensures the stability of the stabilizing plate during use. When not in use, the stabilizing plate can be rotated to a vertical position and secured with a rope for easy carrying. Another strap can secure the sample storage tube for temporary storage after sampling. Four limiting plates can limit and fix the limiting rod to ensure the stability of the land sampling component when not in use.

[0020] This land sampling device for land management is not only stable but also adjustable and easy to carry. Attached Figure Description

[0032] Please see Figures 1 to 3 As shown, a land sampling device for land management, in this embodiment, includes:

[0033] Sampling tube 1, with a land sampling component 2 for land management installed inside the sampling tube 1;

[0034] Two mounting plates 3 are fixedly connected to the outer periphery of the sampling tube 1 and are C-shaped. The inner wall of the mounting plate 3 is rotatably connected to a C-shaped stabilizing plate 4 through a damping shaft. The mounting plate 3 can ensure the stability of the stabilizing plate 4. Multiple spikes 5 to improve stability are welded to the side of the stabilizing plate 4. The side of the stabilizing plate 4 is also provided with a threaded channel, and the threaded channel is threadedly connected to an anchor rod 6. The stabilizing plate 4 is rotated to the lateral position and stepped on to insert the spikes 5 into the ground. Alternatively, the anchor rod 6 can be used to drill into the ground. At this time, the operator stands on the stabilizing plate 4. Compared with the traditional pedal design, the stability is more sufficient, especially for hard and smooth ground, which can ensure the stability of sampling.

[0035] The outer periphery of the sampling tube 1 is provided with multiple discharge channels for discharging material during sampling. The inner wall of the discharge channel is rotatably connected to a movable plate 7, which is fixed to the sampling tube 1 by a latch.

[0036] The sampling components include:

[0037] Assembly disc 21 is set in the inner cavity of sampling tube 1;

[0038] Two limiting rods 22 are welded to the outer periphery of the assembly circular plate 21, and two sliding channels are opened on the outer periphery of the sampling tube 1 for the limiting rods 22 to pass through.

[0039] A forward and reverse motor 23 is installed at the top of the assembly circular plate 21. The output shaft of the forward and reverse motor 23 passes through the assembly circular plate 21 and is connected to a rotating rod 24. A spiral blade 25 for sampling is welded to the outer periphery of the rotating rod 24. A drill bit 26 is welded to the bottom end of the rotating rod 24. When the forward and reverse motor 23 is turned on, the rotating rod 24, spiral blade 25 and drill bit 26 are driven to rotate. The limiting rod 22 is pressed down and moved down, so that the drill bit 26 and spiral blade 25 rotate and move down to sample. After sampling is completed, the limiting rod 22 is lifted up and the soil on the drill bit 26 and spiral blade 25 is removed.

[0040] To improve stability, two limiting arc-shaped plates 27 adapted to the inner cavity of the sampling tube 1 are welded to the top of the assembly circular plate 21.

[0041] In order to store the land, two supporting arc plates 8 are welded to the outer periphery of the sampling tube 1. Multiple sample storage tubes 9 supported by the supporting arc plates 8 are set on the outer periphery of the sampling tube 1. Two binding ropes 10 are glued to the outer periphery of the sampling tube 1, which are respectively tied to the stabilizing plate 4 and the sample storage tubes 9. One of the supporting arc plates 8 is rotatably connected to a limiting plate 11 with four limiting sampling components. The limiting plate 11 is connected and fixed to the other supporting arc plate 8 by a locking buckle.

[0042] The forward and reverse motor 23 is a conventional instrument. Its working principle, size and model are not related to the problem solved by this application, so they will not be described in detail. The I control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0043] Working principle

[0044] The land sampling device for land management is carried to the designated location. The sampling tube 1 is aligned with the land to be sampled. The locking buckle of the limiting plate 11 is opened, the binding rope 10 is released from the fixing of the stabilizing plate 4, the stabilizing plate 4 is rotated to the horizontal position, and the foot is stepped on. The spike 5 is inserted into the soil, or the anchor rod 6 can be used to drill into the soil. At this time, the operator stands on the stabilizing plate 4, turns on the forward and reverse motor 23, drives the rotating rod 24, the spiral blade 25 and the drill bit 26 to rotate, and presses down the limiting rod 22 to move it down, so that the drill bit 26 and the spiral blade 25 rotate and move down to sample. After the sampling is completed, the limiting rod 22 is lifted up, the soil on the drill bit 26 and the spiral blade 25 is taken out and placed in the sample storage tube 9 for temporary storage.
