Description

Soil auger with visible soil sampling depth

technical field

The utility model patent relates to a soil-borrower suitable for visible sampling depth data under various soil environmental conditions, belonging to small-scale manual sampling instruments in agricultural science experiment machinery.

Background technique

my country has a large land area and various land types are widely distributed, and soil augers, as a relatively common soil sampling collection tool, are widely used throughout the country. However, in the various soil sampling processes, due to the different soil depth requirements for the same plot of soil, and different soil properties and topographical conditions, the accuracy requirements for soil depth are becoming increasingly stringent. Especially in areas with different soil distribution types or complex soil structures, it is often necessary to select soil augers and scales according to soil conditions, which is time-consuming and laborious and has low sampling efficiency. It is often a waste of time to take soil with a soil-borrowing drill without a scale size. At the same time, because the soil sampling depth data cannot be read conveniently in many cases, the soil-taking speed is very slow, which affects the progress of the next scientific experiment. The depth of the pits dug before and after the soil is different, which often leads to low accuracy of the soil depth data taken, which greatly reduces the reliability and accuracy of the data.

In the past, the traditional method of soil extraction was to use a traditional soil auger without sampling depth readings to obtain soil, and then use a tape measure or visual inspection to determine the depth of the soil auger in the soil during soil extraction, fix the auger and take it out. This method of taking soil samples has large errors, complicated procedures, low work efficiency, and poor soil sampling depth and controllability. Since it is impossible to directly and conveniently read the depth of the soil sampling drill that has penetrated into the soil, it often occurs that the soil sampling depth is not enough. Or the depth of soil extraction exceeds the required situation, and these situations can only be corrected by re-extracting soil, which not only greatly reduces the efficiency of soil extraction, but also takes time and effort.

Utility model content

In order to solve the above-mentioned problem of collecting soil samples in areas with a relatively high degree of soil environment complexity, obtain soil with a sampling depth that meets the data accuracy requirements, and at the same time reduce the use of tools such as tape measure in the process of soil sampling to reduce the accuracy, and improve soil sampling. Accuracy of depth data, shortening unit sampling time, simple, quick and convenient collection of soil at the depth required by the experiment, hereby proposes a soil auger with visible soil sampling depth suitable for various soil types, used for collecting soil kind of work. The soil drill has a simple structure and is easy to use. The soil drill has a standard scale scale and a metal pull rod scale, which can collect soil samples accurately and quickly, and the drilled soil holes are neat and standardized, which can effectively improve the efficiency and accuracy of soil extraction. Sex, reduce labor intensity, save labor costs, in order to achieve time-saving, labor-saving, labor-saving, and efficient collection of soil samples to the required depth.

Using the utility model patent, that is, the soil sampling drill with visible soil sampling depth to sample the required soil can solve the problem of high complexity of the regional soil environment, effectively obtain soil samples that meet the precision requirements of scientific research, and at the same time reduce the time spent in the soil sampling process. The precision reduction caused by the use of tools such as a tape measure to measure the depth of the soil sample, improves the accuracy of collecting soil samples at different depths, reduces the unit sampling time, and takes the soil samples at the required depth simply, quickly and conveniently. It has the advantages of saving labor time and fast sampling, especially suitable for soil sampling in saline-alkali land and other areas where the soil sample structure is strong and difficult to control the depth of soil penetration, and the sampling efficiency can be significantly improved.

The composition and structure of the earth-absorbing drill with visible soil sampling depth involved in the utility model patent is shown in Figure 1 . It consists of a top anti-break reinforcement cap 1, a handle 2, a main rod 3, a main rod scale 4, a fixed nut 5, a metal pull rod scale 6, an internal connecting shaft 7, a push rod base 8 and a soil sample storage drill bit 9; among them: The main body of the soil drill is composed of a main rod 3 and a soil sample storage bit 9, and the handle 2 is connected to the upper part of the main rod 3; the three parts of the metal pull rod scale 6, the internal connecting shaft 7 and the push rod base 8 are the internal components of the soil drill. The pull rod scale 6 is connected to the upper end of the internal connecting shaft 7, and the push rod base 8 is connected to the lower end of the internal connecting shaft 7; the metal pull rod scale 6 protrudes through the scale opening on the upper part of the main body, and can directly read the depth data of the collected soil sample, and fix the Nut 5 is enclosed within on the metal rod scale 6, plays a fixing role.

Since the utility model patent, the soil auger with visible soil sampling depth, uses a ruler to display the depth of the soil sample storage drill bit, so it is not limited by the depth of the soil sample storage drill bit on the reading of the scale, compared with the marking marks of the traditional soil auger The scale method or tape measure method has the advantages of not needing to repeatedly draw or measure the scale, and it is easier to read the depth data. At the same time, the rigid metal rod scale avoids errors caused by multiple marking scales or measurement readings, which is not only more convenient but also greatly improves Accuracy of taking soil sample depth data.

At the same time, because the soil sampling drill with visible soil sampling depth adopts the design of the metal scale rod and the push rod base inside the soil sample storage drill bit, it is easier for the operator to take out the soil left inside the drill bit, which greatly reduces the need for soil extraction. In the process of taking out the soil from the inside of the drill bit, the operator can push the circular push rod base located at the top of the soil sample storage drill bit, and give the soil inside the drill bit a vertical direction from the top of the soil sample storage drill bit. The lower force, so as to better cooperate with the work of the soil-borrowing knife, makes the soil be taken out from the soil sample storage bit faster and more completely, which greatly improves the efficiency of soil-borrowing.

Detailed ways

Introduce below in conjunction with accompanying drawing 1 the visible earth-borrowing drill of the soil sampling depth described in the utility model patent. The soil sampling drill with visible soil sampling depth is composed of a top anti-break reinforcement cap 1, a handle 2, a main rod 3, a main rod scale 4, a fixing nut 5, a metal pull rod scale 6, an internal connecting shaft 7, a push rod base 8 and soil Sample storage drill bit 9 forms.

The main body of the soil drilling drill is composed of a main rod 3 and a soil sample storage drill bit 9, and the main rod 3 and the soil sample storage drill bit 9 are connected into one body through a threaded connection. The handle 2 is connected with the top of the main rod 3 through a threaded connection.

The internal components of the earth-boring drill include three parts: a metal rod scale 6, an internal connecting shaft 7 and a push rod base 8. The metal pull rod scale 6 is connected with the upper end of the internal connecting shaft 7 through threaded connection, and the push rod base 8 is connected with the lower end of the internal connecting shaft 7 through high temperature welding.

A scale 4 can be arranged on the main rod of the soil drilling drill, and the scale takes 1cm as a unit, and the scale range is from 0-120cm or from 0-100cm.

The handle 2 of the soil drilling drill, the main rod 3 and the soil sample storage drill bit 9 are all made of 304 stainless steel pipes.

The top anti-break reinforcement cap 1 is specially made and is made of stainless steel blocks. After design, the top of the anti-break reinforcement cap for soil drilling drills uses a flat surface instead of an arc surface, which is more suitable for contact with a hammer. The force is more uniform, which can prolong the service life of the soil drill; the top anti-break reinforcement cap 1 is connected with the main rod 3 of the soil drill through threads, which is convenient for disassembly and replacement after damage, and at the same time can ensure the main rod 3 of the soil drill connected to it It is not subject to direct hammering, and plays a role in protecting the main rod, preventing it from being bent or even broken by force.

Accompanying drawing 2 is the exterior view of a preferred embodiment of the earth-absorbing drill whose soil sampling depth is visible according to the utility model patent, as shown in the figure, the main rod 3 of the earth-absorbing drill can also adopt two cut circles with slightly different diameters Tubes are connected. The soil sample storage drill bit 9 of the earth-borrowing drill can also adopt the sharp angle shape as shown in the accompanying drawing 2 except that it can adopt the circular arc shape as shown in the accompanying drawing 1.

Accompanying drawing 3-1 to accompanying drawing 3-5 are the use diagrams of the earth-absorbing auger with visible soil sampling depth described in the utility model patent. When taking soil samples, it depends on different situations. Generally, two people can operate it. In case of a strong soil structure or unfavorable terrain conditions for normal sampling, three to four people should cooperate to use the utility model—— Soil-absorbing augers with visible soil sampling depth have better effect and higher efficiency. The process of collecting soil samples can be carried out by A and B in cooperation. A is responsible for holding the soil auger and fixing it on the hole where the soil needs to be extracted, and observing the depth of the soil auger into the soil. B is responsible for holding the hammer to remove the soil. Drilling and hammering into the soil, division of labor and cooperation, each perform their duties, can significantly improve the efficiency of soil extraction. The specific work steps are as follows:

The first step, as shown in Figure 3-1, after selecting the exact place to take the soil sample, the first hand holds the handle of the soil drill, aligns the soil sample storage drill bit with the soil sampling point, and then looks at the metal pull rod scale, At this time, the reading of the scale is zero, and then B holds the hammer and hammers the soil borrow drill into the soil. At this time, pay attention to the top anti-break reinforcement cap at the hitting point, and try to hit with the center of the hammer to protect the soil borrow drill. , prolong its service life;

The second step, as shown in Figure 3-2, after the soil auger is inserted into the soil, as B continues to hit, the soil auger will go deep into the soil, and at this time the reading of the metal rod scale will change accordingly, and A In the process of watching its changes, B can be reminded to control the strength of the hammer at any time;

The third step, as shown in Figure 3-3, when the reading reaches the required soil depth, B will stop hitting. At this time, A can fix the fixing nut on the metal pull rod scale, so that the soil sample can be stored in the drill bit. The soil sample is not affected by external force;

Step 4, as shown in Figure 3-4, A holds the handle of the soil drill and lifts the main rod of the soil drill vertically. At this time, the collected soil has been separated from the soil in the soil sample storage drill bit. It is clear that this process may be relatively laborious due to the difference in the structure or humidity of the soil to be taken, and it can be completed by two people at this time;

The fifth step, as shown in Figure 3-5, A carefully puts the soil sample storage drill bit into the soil bag and uses a soil shovel to put the soil sample into the bag, at this time, B loosens the fixing nut on the metal rod scale, And can hold the metal pull rod ruler to assist A to push the soil sample deeper inside the soil sample storage drill bit into the soil sample bag, so that no residual soil sample is left in the soil sample storage drill bit.

As mentioned above, a complete process of collecting the required soil samples by using the soil auger with visible soil sampling depth has been completed.

Contrast the soil-borrowing process of the old and new two kinds of soil-borrowing drills, and the technical effect of the utility model patent can be seen. It takes about 10 minutes for a traditional soil drill to collect a soil sample taken in six layers within a depth of 1 meter, but it only takes about five minutes to obtain a soil sample by using the utility model patent, which saves In half the time, the work efficiency is higher and the effect is more significant; in addition, the accuracy of depth control of the soil sample obtained by using the utility model patent is also high, which is 15% higher than the accuracy of the soil depth obtained by the traditional soil auger about.
