Problems solved by technology

The determination of soil bulk density usually adopts the ring knife method. The conventional method is to hammer the ring knife into the soil with an energy-absorbing hammer, and then take out the ring knife filled with soil, and the commonly used ring knife is mostly used for surface sampling, and deep sampling needs to be used. The method of digging pits, such as 100cm deep, generally requires excavating pits of more than 100cm in length, width and depth, which requires a lot of work and low efficiency
[0004] In the existing sampling technology, due to the long-term, large-scale, and blind use of traditional samplers, a lot of money and labor are consumed, and a large amount of scientific research work is wasted on the collection of soil samples in the field.

Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Such as figure 1 As shown, the present invention provides a convenient soil extractor that can be used to test the bulk density of deep soils, including a base 2, auger rod 3, a geared pull rod 4, and a sampling tube 5; wherein the base 2 is connected to the ground Fixed connection. A pair of geared pull rods 4 are installed at the top of the base 2. The spiral drill rod 3 is fixed between a pair of geared pull rods 4 to form a gear system; the geared pull rod 4 includes a gear 41 and is arranged on the gear 41 The pull handle 42 o...

Abstract

The invention discloses a convenient earth-taker which can be used for testing the bulk density of deep soil, which comprises a base, an auger rod, a geared lifting rod, and a sampling tube; wherein, the base is fixedly connected with the ground, and a top of the base is installed with a For the pull rod with gear, the auger rod is fixed between a pair of pull rods with gear to form a gear system; the thread on the auger rod meshes with the gear on the pull rod with gear to form a lever system; the sampling tube is installed on the auger The bottom end of the drill pipe; the up and down movement of the auger drill pipe is realized by pressing down or lifting the gear pull rod, and the use of the spiral and lever principles can make the earth taker in the present invention more labor-saving, quickly enter the soil and pull out the soil, reducing Soil disturbance improves the accuracy of soil scientific research, while reducing the labor intensity of the sampling process and improving work efficiency.

Description

Technical field [0001] The invention relates to the technical field of soil borrowing, in particular to a convenient soil borrower which can be used to test the bulk density of deep soil. Background technique [0002] Soil is one of the resources for obtaining high-yield, high-quality and high-efficiency in agricultural production. The study of deep soil properties is an important aspect of agricultural production. However, due to insufficient technology and equipment for obtaining deep soil samples, the research on deep soil layers is seriously hindered. At present, although there are various electric soil borrowing devices on the market, they have not been promoted due to the limitation of field power or their complexity and cost. Although the commonly used manual soil-boring tools are relatively portable, it is difficult to drill down in the soil compacted plots below 40cm, and due to the large friction between the soil and the soil auger, it is very laborious to pull out the ...
