Description
Technical Field
the utility model relates to a soil property sampling technical field, especially a soil quality testing device that fetches earth.
Background
Soil quality detection tests are required before greening planting, and soil samples are collected within the ranges of 0-30cm, 30-60cm and 60-90cm below the ground surface respectively. The traditional core drilling machine can meet the requirement of a sampling range, but due to the self property of soil mass, the core drilling machine cannot integrally take out a soil sample after drilling to a specified position, so that a small excavator is adopted on site to take out soil, but the method has the defects that: the soil sample position is not accurate, the accuracy of test data is reduced, the operation is complex, and the sampling cost is high.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned condition, for overcoming prior art's defect, the utility model provides a soil quality testing device that fetches earth, effectual solved current soil sample position inaccuracy, test data accuracy reduce, the operation is complicated, drop into the problem that the sample is with high costs.
the technical scheme who solves is, including vertical form and can initiative pivoted first drum, first drum lower extreme cover is equipped with detachable second drum, and the second drum can rotate along with first drum, is fixed with coring knife on the second drum lower extreme inner wall, and coring knife is the heliciform and fixes.
The utility model discloses think about ingenious fine solution soil property sample inaccuracy under the condition restriction, current mechanical equipment be difficult problem such as not suitable, and compare with traditional approach, test data is more accurate, easy operation to manpower and material resources, reduce cost, improvement work efficiency have been saved.
Drawings
Fig. 1 is a structural diagram of a first cylinder of the present invention.
Fig. 2 is a structural diagram of a second cylinder of the present invention.
Fig. 3 is a structural diagram of the coring knife of the present invention.
Detailed Description
The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings.
By figure 1 to figure 3, the utility model discloses a vertical form just can initiative pivoted first drum 1, and the end cover is equipped with detachable second drum 2 under the first drum 1, and second drum 2 can rotate along with first drum 1, is fixed with coring sword 3 on the 2 lower extreme inner walls of second drum, and coring sword 3 is the heliciform fixed.
In order to realize the detachability of the second cylinder 2, the outer side wall of the first cylinder 1 is connected with the inner side wall of the second cylinder 2 through screw threads, and the second cylinder 2 is screwed on the first cylinder 1 through screw threads.
In order to facilitate the observation of the sampling depth, the outer side wall of the first cylinder 1 is marked with scales.
It is worth noting that the thread structure between the first cylinder 1 and the second cylinder 2 has the same direction of rotation as the coring blade 3; in the shape of the device, the coring knife 3 serves as a bottom plate of the second cylinder 2 and is used for placing the taken soil sample to be loose; the first cylinder 1 is fixed to the second cylinder 2 in many ways, for example by removable pins; the scales on the outer side wall of the first cylinder 1 indicate the soil taking depth, such as 30cm, 60cm and 90cm … …; the upper end of the first cylinder 1 is fixed with an output shaft of the core drilling machine, and the output shaft on the core drilling machine drives the first cylinder 1 to rotate.
When the device is used, the second cylinder 2 is screwed on the first cylinder 1 and fixed, then the upper end of the first cylinder 1 is fixed with an output shaft of a core taking machine, the core taking machine drives the first cylinder 1 to rotate, the first cylinder 1 drives the second cylinder 2 to rotate, a spiral coring knife 3 at the lower end of the second cylinder 2 drills a hole downwards, a soil sample is placed in the first cylinder 1 and the second cylinder 2, the core taking knife 3 stops rotating and downwards digging operation after reaching a specified depth, and the core taking cylinder is slowly lifted, so that the soil sample is prevented from scattering; after the soil sampling operation is completed, the structure of the coring knife 3 can be dismantled, and a soil sample is taken out.
the utility model has the advantages that:
1. The design of the thread can lead the structure of the coring knife 3 to be tightly connected with the coring barrel to form a whole;
2. The setting of the scale marks can accurately position the sampling range, and the accuracy of the sample is ensured;
3. The structure of the coring knife 3 can be used for cutting soil, and the cut soil can be conveyed to the coring barrel in the rotating process;
4. The structural chassis of the coring knife 3 can be used as a coring barrel support bottom to ensure that soil is not scattered;
5. The structure of the coring cutter 3 is suitable for the first soil and the second soil with soft soil;
6. Compared with the traditional coring device, the device does not need to operate with water, avoids the increase of the water content of the soil sample, and reduces the accuracy of the experiment;
7. first drum 1 in this device is with the coring sword 3 that uses commonly in the work of coring of cement stabilized macadam and asphalt concrete as the prototype to reequip, so accomplish the back at this device coring, dismantle second drum 2 and coring sword 3, first drum 1 in this device can continue to be used for cement stabilized macadam and asphalt concrete to core the work, does not cause irreversible damage to former equipment.
The utility model discloses think about ingenious fine solution soil property sample inaccuracy under the condition restriction, current mechanical equipment be difficult problem such as not suitable, and compare with traditional approach, experimental data is more accurate to manpower and material resources, reduce cost, improvement work efficiency have been saved.
