Description

A deep soil fetcher

technical field

The invention relates to a soil fetching device for soil sampling, in particular to a soil fetching device capable of collecting deep soil.

Background technique

Agricultural soil is one of the high-yield, high-quality, and efficient resources for agricultural production. Changes in soil moisture and nutrients affect crop yields. In recent years, with the extensive use of chemical fertilizers, the nutrients in the soil surface have been seriously lost, and the nitrogen infiltrated with the ground water has changed the nutrient structure in the deep soil. At the same time, the study of deep soil moisture content and its change law can effectively use the moisture characteristics of the soil itself to conduct research on drought-resistant cultivation techniques and provide a basis for ensuring crop yields.

The study of nutrient and water changes in deep soil has become an important aspect in agricultural production, but the acquisition of deep soil samples is seriously hindered by the lack of technology and equipment. At present, the soil drills used by Chinese scientific researchers are about 1m long, and can only take soil samples of about 1m in the soil layer. In arid areas, due to soil compaction and other reasons, it is difficult to drill below 40cm, which seriously reduces the efficiency of soil sampling. At the same time, it consumes a lot of manpower and material resources. The long-term, large-scale, and blind use of traditional samplers consumes a lot of money and labor, so that the focus of scientific research is not on the laboratory, but a lot of waste on the collection of soil samples in the field.

Traditionally, “Luoyang shovels” are used to collect deep soil samples, but due to improper soil sampling techniques, the samples will be destroyed, and the lower pestle is completely used as power, so the labor efficiency is low. According to field statistics, 3m deep The soil layer takes about 1 hour on average. Moreover, the length of the soil sample taken out is difficult to control, because there is no standardized length, so it is not easy to carry during transportation. It is urgent to use new equipment and methods to sample deep soil in production and scientific research. In the research of agricultural production and soil ecological environment, it can make up for the shortcomings of traditional soil borrowers, and it can be used for the research of deep soil nutrients and water.

Contents of the invention

The object of the present invention is to provide a deep soil soil fetcher with simple structure, convenient assembly, easy use and high working efficiency.

The invention discloses a soil fetcher for deep soil, which comprises a base box, a hollow drill bit, and a sampling pipe. The power output shaft of the reducer is tooth-connected with the auger rod, the sampling pipe is arranged inside the auger rod, and the top end of the auger rod is connected with a hollow drill bit.

When in use, fix the base box on the ground, assemble the hollow drill bit with the sampling tube and a section of auger drill pipe and insert it into the base box, connect with the power output shaft of the reducer, and pass through the pedal pressure rod. Drive the reducer to work, so that the auger rods are slowly drilled into the soil. When the auger rods are about to enter the base box, connect another auger rod to it. The length of each auger rod is a fixed standard size In this way, it is easy to measure the depth of drilling into the ground. After drilling to the required depth, you only need to pedal the pressure rod in reverse, and the auger rod drives the sampling tube and the hollow drill bit to take out the deep soil sample in good condition. .

Therefore, based on the traditional soil soil sampler, using the principle of spiral and lever, and using a separate design, it not only meets the needs of deep soil sampling, but also saves labor and high efficiency. The advantages of high efficiency are of great significance to the study of soil resources. the

Detailed ways

Example 1

A deep soil soil fetcher comprises a base case 1, a hollow drill bit 6, a sampling pipe 5, a speed reducer 2 is arranged in the base case 1, a power shaft of the speed reducer 2 is connected with a pedal pressure rod 3, and the speed reducer The power output shaft of the device 2 is tooth-connected with the auger rod 4, the sampling pipe 5 is arranged inside the auger rod, and the top end of the auger rod 4 is connected with a hollow drill bit 6.

When in use, fix the base case 1 on the ground, assemble the hollow drill bit 6 with the sampling pipe 5 and a section of auger rod 4 and insert it into the base case 1, and connect it with the power output shaft of the reducer 2, Through the pedal pressure rod 3, the speed reducer 2 is driven to work, so that the auger rod 4 is slowly drilled into the soil. The length of the auger rod 4 is a fixed standard size, so that it is easy to measure how deep it is drilled into the ground. After drilling to the required depth, you only need to pedal the pressure rod 3 in reverse, and the auger rod 4 drives the sampling tube. 5 and hollow drill bit 6 just can take out the deep layer soil sample that gets well.
