Abstract
Description
Technical Field
[0001] This utility model relates to the field of soil collection devices, and more particularly to a soil collection device for land reclamation. Background Technology
[0002] Soil collection is a crucial step in land remediation, playing a vital role in soil analysis, land improvement, and soil reuse. When collecting surface soil samples, it is necessary to collect surface bulk density samples. Each bulk density sample is placed in a separate self-sealing bag, typically three replicates are collected together in a single self-sealing bag, and a sample label is attached, indicating the bulk density.
[0003] Currently, the sampling process involves first using a stainless steel shovel or spade to collect samples, then placing the samples on a weighing platform to weigh them. Once the weight is sufficient, the samples are bagged into self-sealing bags. If the first sampling is insufficient, a second sampling is required, and the above steps are repeated. When collecting surface samples, some require multi-point mixed sampling, while others require individual sampling. Samples from different locations are all placed on the weighing platform using a stainless steel shovel or spade. This operation can easily lead to confusion between samples from different locations during the collection, weighing, and packaging steps. Residual soil on the stainless steel shovel or spade can easily be carried into the sample collected from the next location, thus affecting the accuracy of subsequent analysis.
[0004] The existing solution involves manually cleaning the surface of a stainless steel shovel or spade each time a sample is collected from a different location, which is time-consuming and labor-intensive. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a soil collection device for land reclamation with a built-in cleaning function, which can clean the surface of the shovel head after each use, reducing the carrying rate of residual soil.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: a soil collection device for land reclamation, including a sleeve, a cleaning box, a connecting rod, a handle, and a shovel head; the sleeve has a hollow internal structure with openings at both the top and bottom, the bottom end of the sleeve is connected to the cleaning box, and the cleaning box has a hollow internal structure with openings at both the top and bottom; the connecting rod runs through the inside of the sleeve, the top end of the connecting rod is connected to the handle, and the bottom end of the connecting rod is connected to the shovel head; a tension spring is provided inside the sleeve, and the connecting rod is located on the outer wall inside the sleeve and connected to a limiting ring; one end of the tension spring is connected to the top end of the sleeve, and the other end of the tension spring is connected to the limiting ring; in its natural state, the tension spring is in a contracted state, at which time the shovel head is completely located inside the cleaning box; when the tension spring is stretched downwards, the shovel head can be fully extended from the bottom end of the cleaning box.
[0007] The cleaning box is equipped with cleaning brushes on the inner walls of the front, back, left and rear sides. When the cleaning brushes come into contact with the shovel head, they can effectively scrape off the soil remaining on the surface of the shovel head.
[0008] The inner cavity of the cleaning box is larger than the shovel head, and the opening at the bottom of the cleaning box is larger than the shovel head, so that the shovel head can smoothly enter and exit the cleaning box.
[0009] The side wall of the cleaning box and the side wall of the connecting rod are provided with through holes at corresponding positions. The outer wall of the cleaning box is connected to the limiting post by the traction rope. The limiting post is connected to the through hole. When the limiting post is inserted into the through hole on the side wall of the cleaning box and the side wall of the connecting rod, the position of the connecting rod is fixed and cannot move up and down with the tension spring, thus facilitating the shoveling operation.
[0010] The beneficial effects of this utility model are:
[0011] (1) After each shoveling operation, the limiting post of the soil collection device for land remediation can be pulled out, and the connecting rod can be pulled upward into the cleaning box under the tension of the tension spring. The staff can hold the sleeve and the handle with both hands respectively, and manually push the handle downward to make the shovel head move in and out of the cleaning box. During this process, the cleaning brush in the cleaning box contacts and rubs against the shovel head, scraping off the residual soil on the surface of the shovel head, which helps to reduce the carrying rate of residual soil.
[0012] (2) The soil collection device for land remediation is equipped with a tension spring acting on the connecting rod. When not in use, the limiting post can be pulled out, and the tension spring pulls the connecting rod upward, so that the shovel head automatically retracts upward into the cleaning box, preventing the shovel head from being exposed to the outside and collided, worn or accidentally injured.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.
[0021] Reference Figure 1-5 This embodiment provides a soil collection device for land reclamation, including a sleeve 1, a cleaning box 2, a connecting rod 3, a handle 4, and a shovel head 5. The sleeve 1 has a hollow interior with openings at both the top and bottom. The bottom end of the sleeve 1 is fixedly connected to the cleaning box 2, which also has a hollow interior with openings at both the top and bottom. The connecting rod 3 runs through the inside of the sleeve 1. The top end of the connecting rod 3 is bolted to the handle 4, and the bottom end of the connecting rod 3 is bolted to the shovel head 5. A tension spring 6 is provided inside the sleeve 1, and a limiting ring 7 is fixedly connected to the outer wall of the connecting rod 3 inside the sleeve 1. One end of the tension spring 6 is bolted to the top end of the sleeve 1, and the other end is bolted to the top of the limiting ring 7. In its natural state, the tension spring 6 is in a contracted state, at which time the shovel head 5 can be completely located inside the cleaning box 2. When the tension spring 6 is stretched downwards, the shovel head 5 can be completely extended from the bottom end of the cleaning box 2.
[0022] To clean the soil from the surface of the shovel head 5, the cleaning box 2 is equipped with numerous cleaning brushes 8 on its four inner walls (front, back, left, and rear). These cleaning brushes 8 are preferably wire brushes, which possess good elasticity and toughness, effectively scraping off residual soil from the surface of the shovel head 5 upon contact. The cleaning box 2 is assembled from stainless steel plates and bolts; unscrewing the bolts allows for the removal of the cleaning box 2, enabling thorough cleaning or replacement of the internal cleaning brushes 8.
[0023] Preferably, the inner cavity of the cleaning box 2 is larger than the outer diameter of the shovel head 5, and the opening at the bottom of the cleaning box 2 is larger than the outer diameter of the shovel head 5, so that the shovel head 5 can smoothly enter and exit the cleaning box 2.
[0024] Preferably, the side wall of the cleaning box 2 and the side wall of the connecting rod 3 are provided with through holes 9 at corresponding positions. The outer wall of the cleaning box 2 is connected to the limiting post 11 by the traction rope 10. The limiting post 11 is connected to the through hole 9. When the limiting post 11 is inserted into the through hole 9 on the side wall of the cleaning box 2 and the side wall of the connecting rod, the position of the connecting rod 3 is fixed and cannot move up and down with the tension spring 6, thus facilitating the shoveling operation.
[0025] When this device is not in use, such as Figure 1-2As shown, the tension spring 6 is in a naturally contracted state, and the limiting post 11 is in a pulled-out state. At this time, the shovel head 5 is completely inside the cleaning box 2, which is convenient to carry and avoids accidental injury from the shovel head 5.
[0026] When using this device, if Figure 3-4 As shown, the tension spring 6 is in a downward stretched state, and the limiting post 11 is inserted into the through hole 9 to fix the connecting rod 3 and the cleaning box 2. At this time, the shovel head 5 is fixed in position and will not retract, so it can be used for shoveling. When it is necessary to clean the surface of the shovel head 5, the bottom opening of the cleaning box 2 can be turned downwards, one hand can hold the sleeve 1, and the other hand can hold the handle 4. Move the handle 4 up and down back and forth to drive the shovel head 5 to move in and out of the cleaning box. During this process, the cleaning brush 8 repeatedly contacts the surface of the shovel head 5, and the scraped soil falls from the opening at the bottom of the cleaning box 2.
[0027] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of this utility model and are not intended to limit this utility model. This utility model has been described in detail with reference to preferred embodiments. Those skilled in the art should understand that any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model do not depart from the spirit of this utility model and should also fall within the protection scope of the claims of this utility model.
