Description

Technical Field

[0001] This utility model relates to the field of land measurement and sampling technology, specifically a land measurement and sampling device for land approval operations. Background Technology

[0002] The land sampling device for land approval operations is a device used to actually sample soil from designated land during the land approval process.

[0003] Based on the above, the inventors have discovered that: Currently, there are many land sampling devices for land approval operations on the market. However, in general, these devices require staff to directly use a soil sampling drill to sample the land. Furthermore, obtaining soil samples at different depths requires staff to carry soil sampling drills of varying lengths. After sampling, the drill must be slowly excavated using a shovel, increasing the workload for staff and reducing the device's practicality. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a land sampling device for land approval operations, aiming to achieve greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a land sampling device for land approval operations, comprising a sleeve column, a fixed rod slidingly attached to the inner wall of the sleeve column, a soil sampling cylinder fixed to the bottom end of the fixed rod, an adjustment mechanism on one side of the sleeve column, and a pushing mechanism on the outer wall of the fixed rod.

[0006] The adjustment mechanism includes:

[0007] A drive motor is provided, with one side of the drive motor fixed to one side of the sleeve. A connecting hole is provided on the inner wall of the sleeve, and a gear is provided on the inner wall of the connecting hole. A rack is driven on the outer wall of the gear. The rack is located on the inner wall of the sleeve, and one side of the rack is fixed to one side of the fixing rod.

[0008] As a preferred embodiment of this utility model, a top plate is fixed to the top of the sleeve column, and two handles are fixed to the inner wall of the top plate.

[0009] As a preferred embodiment of this utility model, a base is fixedly provided on one side of the sleeve column, and the inner wall of the base is provided on the outer wall of the gear.

[0010] As a preferred embodiment of this utility model, the driving mechanism includes:

[0011] A push plate is installed on the inner wall of the soil sampling cylinder. Two connecting plates are fixed to the top of the push plate. The outer walls of the two connecting plates are sleeved with the top of the soil sampling cylinder. One side of each connecting plate slides against the outer wall of the fixing rod.

[0012] As a preferred embodiment of this utility model, the inner walls of the two connecting plates are fitted with horizontal columns, the outer walls of the horizontal columns are matched with the inner walls of the fixing rods, and the two ends of the horizontal columns are provided with grooves.

[0013] As a preferred embodiment of this utility model, the base is fixed with support plates on both sides, and the inner walls of the two support plates are fitted with inserts, with one side of each insert matching the inner wall of the insert.

[0014] As a preferred embodiment of this utility model, each of the two support plates has a concave plate on one side, each of the two concave plates is fixed to one side of the sleeve post, each of the two concave plates has a limiting post fitted on its inner wall, and one end of each of the two limiting posts is matched with the inner wall of the insert post.

[0015] The beneficial effects of this utility model are:

[0016] 1. This solution uses a drive motor to rotate a gear, which in turn drives a rack and pinion to slide a fixed rod on the inner wall of the sleeve. This allows staff to adjust the height of the fixed rod according to the depth of soil sampling, eliminating the need for staff to carry soil burrs of different lengths to sample the soil at different depths. This reduces the workload of staff and allows for better actual soil sampling during land approval procedures, effectively improving the effectiveness of the device.

[0017] 2. In this scheme, the soil sampling tube is inserted into the soil by controlling the handle until it reaches the specified depth. After that, it is removed, and the groove block and cross column are removed in sequence. The connecting plate slides on the outer wall of the fixed rod to drive the push plate to push the soil sampled inside the soil sampling tube completely out. This avoids the need for workers to use shovels to remove the soil sampled inside the soil sampling tube one by one. This ensures that the device can better and faster push out the soil sampled inside the soil sampling tube, which is beneficial for subsequent field sampling of the land and improves the practicality of the device.
