Description

Technical Field

[0001] The utility model belongs to the technical field of soil sample leveling, in particular to a device for leveling the surface of a whole section of soil sample. Background Art

[0002] The third national soil survey is an important method to identify soil types and distribution patterns, as well as the quantity and quality of soil resources. The survey results can provide scientific support for the scientific classification, planned utilization, improvement and fertilization, protection and management of soil, and can also provide a basis for decision-making in the formulation of major policies for economic, social and ecological construction. Among various soil samples, whole-section soil samples are the most important sample data.

[0003] The whole soil sample has the characteristics of maintaining the original natural state of the soil to the greatest extent, making the soil structure and soil properties intact and truly reflecting the characteristics, and is the most important sample among the many samples collected in this census. In order to preserve and safely transport the whole sample, the whole sample needs to be fixed and sealed, and the surface of the soil sample must be leveled before the wooden boards on both sides can be fixed, so the surface leveling of the soil sample is particularly important.

[0004] When the whole soil sample is taken out, since it is a whole piece of soil dug out, the soil sample will be higher than the sampling wooden box. The excess soil must be removed and leveled before the surface wooden board can be fixed. If the manual leveling method is used with a knife, it is necessary to repeatedly smooth the cross-section of the soil sample, which not only seriously affects the leveling speed, but also easily causes soil sample contamination, and the efficiency is low. Therefore, it is urgent to improve the existing soil sample leveling method and provide a soil whole sample surface leveling device. Utility Model Content

[0009] As a preferred embodiment, the scraping and leveling assembly includes a scraper, a limit block, an inclined portion and a fixed hook. The scraper is movably located between the two cross bars. The limit blocks are symmetrically fixed on the left and right outer walls of the scraper. The rear end of the scraper is provided with an inclined portion, and a fixed hook is welded on the middle outer wall of the inclined portion.

[0010] As a preferred implementation, one end of the two limit blocks away from the scraper extends to the inner side of the two limit grooves respectively, and the limit blocks are engaged and slidably connected with the cross bar.

[0024] The embodiments described below are only some of the embodiments of the present invention and do not represent all the embodiments consistent with the present invention. Now, in conjunction with the accompanying drawings, the exemplary embodiments are described as follows:

[0025] like Figure 1-4 As shown, the utility model shows a device for leveling the surface of a whole section of soil samples, which comprises a sampling box 1, a docking frame 2 is provided on the outer side of the top of the sampling box 1, cross bars 3 are symmetrically fixed above the left and right ends of the docking frame 2, one end of the two cross bars 3 is provided with a soil scraping and leveling assembly 5, the other end of the two cross bars 3 is installed with a horizontal axis 6, the right end of the horizontal axis 6 is fixedly connected to a handle 7, a winding wheel 8 is provided on the fixed outer sleeve of the middle part of the horizontal axis 6, and a connecting rope 9 is fixedly connected to the outer wall of the winding wheel 8.

[0026] On the basis of the above structure, the distance between the two cross bars 3 is smaller than the external width of the sampling box 1 , and the two cross bars 3 are provided with limiting grooves 4 inside.

[0027] In this embodiment, the cross bar 3 is provided so that the device can be stably sleeved on the top outer side of the sampling box 1, and the limiting groove 4 is provided to improve the stability of the scraping and leveling assembly 5 during movement.

[0028] On the basis of the above structure, the scraping and leveling assembly 5 includes a scraper 51, a limit block 52, an inclined portion 53 and a fixed hook 54. The scraper 51 is movably located between the two cross bars 3. The limit blocks 52 are symmetrically fixed to the left and right outer walls of the scraper 51. The rear end of the scraper 51 is provided with an inclined portion 53, and a fixed hook 54 is welded to the middle outer wall of the inclined portion 53.

[0029] In this embodiment, the inclined portion 53 can be used to reduce the resistance encountered by the scraper 51 during the process of moving and scraping the soil, thereby facilitating rapid scraping and leveling of the soil sample.

[0030] On the basis of the above structure, one end of the two limit blocks 52 away from the scraper 51 extends to the inner side of the two limit grooves 4 respectively, and the limit blocks 52 are engaged and slidably connected with the cross bar 3.

[0031] In this embodiment, the limiting block 52 is provided to facilitate the scraper 51 to slide stably along the limiting groove 4 .

[0032] On the basis of the above structure, the two ends of the horizontal axis 6 are respectively connected to the two cross bars 3 with bearings, and the winding wheel 8 is an "I"-shaped structure.

[0033] On the basis of the above structure, the connecting rope 9 is made of nylon, and one end of the connecting rope 9 away from the winding wheel 8 is fixedly connected to the outside of the fixing hook 54 , and the connecting rope 9 forms a winding structure on the outside of the winding wheel 8 .

[0034] In this embodiment, the winding wheel 8 is driven to rotate by the horizontal axis 6, so that the connecting rope 9 can be wound up, thereby facilitating the pulling of the scraping and leveling component 5 to move, which is more labor-saving. Moreover, the movement of the scraping and leveling component 5 can achieve a one-time leveling of the soil sample, avoiding repeated leveling and causing contamination of the soil sample.

[0035] The working principle of the utility model is as follows:

[0036] When in use, first use the sampling box 1 to collect soil samples, and then, Figure 1 As shown in FIG, the docking frame 2 is placed flat on the ground, and then the docking frame 2 is sleeved on the outside of the top of the sampling box 1. At this time, since the distance between the two cross bars 3 is smaller than the outer width of the sampling box 1, the docking frame 2 can be positioned on the outside of the top of the sampling box 1;

[0037] Then, the handle 7 is used to control the rotation of the horizontal axis 6 and the winding wheel 8, and the winding wheel 8 is used to wind the connecting rope 9. By winding up the connecting rope 9, the fixing hook 54 can be pulled to drive the entire soil scraping and leveling assembly 5 to move backward along the limiting groove 4 in a stable and horizontal manner, so that the part of the soil sample that is higher than the sampling box 1 can be quickly scraped off once and for all, which is convenient for quickly and efficiently leveling the top surface of the soil sample. After the soil is leveled, the docking frame 2 can be directly removed, and the inclined portion 53 provided at one end of the scraper 51 is convenient to reduce the resistance of the scraper 51 when leveling the soil sample, and the operation is more labor-saving;

[0038] Compared with traditional soil sample leveling, this leveling device is not only quick to assemble and disassemble, easy to use, but also can achieve rapid leveling of soil samples with high efficiency, without the need for repeated leveling, and can also avoid contamination of soil samples, making it more practical.

[0039] The above are only preferred specific embodiments of the utility model and are not intended to limit the protection scope of the utility model; any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
