Sample presser workstation for gravelled graphitized soil and manufacturing method of sample presser workstation

Abstract

The invention relates to a sample presser workstation for gravelled graphitized soil and a manufacturing method of the sample presser workstation. The sample presser workstation comprises a bottom plate, a first side plate, a second side plate and a cuboid top block, wherein the bottom plate is provided with two first trapezoid dovetail grooves and two rectangular grooves; the bottom of the firstside plate is a trapezoid wedge, and the side surface is provided with a second trapezoid dovetail groove; the bottom of the second side plate is a rectangular wedge, two ends of the side surface arerespectively provided with a trapezoid wedge; all grooves are matched with the wedges by virtue of a sodium silicate-based high-temperature-resistant high-strength adhesive medium; the bottom plate, the first side plate and the second side plate adopt a glass-encapsulated ceramic sand complex structure, the glass of the complex structure is toughened by virtue of a two-step ion exchanging way, andthe surface glass is also treated in a bionic lubricating manner. The sample presser workstation is suitable for the soil with a complicated hard environment, and is resistant to abrasion, fatigue, impact and corrosion and high in strength.

Description

technical field [0001] The invention relates to the field of agricultural tools, in particular to a press station for sandy and graphitized soil and a manufacturing method thereof. Background technique [0002] The working station of the sample press can be regarded as a relatively homogeneous material. During the working process, the working station will bear very complicated stresses under the joint action of the hammer impact energy, the self-gravity of the working station and the reaction force of the soil layer. The parts vary in size. The steel plate of the standard station is not insignificant in terms of its thickness and size. However, under such a huge impact energy, the steel plate as a rigid material will be deformed. In conventional technology, bolts are often used for fastening, resulting in multiple components. If there is a gap between them, it will cause additional vibration and impact, and even lead to loosening and failure. However, the thickness of the ...

Problems solved by technology

The steel plate of the standard station is not insignificant in terms of its thickness and size. However, under such a huge impact energy, the steel plate as a rigid material will be deformed. In conventional technology, bolts are often used for fastening, resulting in multiple components. There is a gap between them, which will cause additional vibration and impact, and even lead to loosening and failure

However, the thickness of the steel plate used in the station used in the conventional technology and the external dimensions of the station tip are far from the requirements of the actual high-intensity continuous operation. When there is a sudden change in the hard soil layer, the huge impact energy will directly act on the press station, which will easily lead to fragmentation and wear

Another important reason for the failure of the press station of the prior art is corrosion. Conventional high-strength steels have poor corrosion resistance, and the soil is moist and contains a variety of minerals and acid-base media, which is prone to corrosion. Corrosion of the station part of the sample press in the conventional technology, especially the connection part

In the agricultural application of some specific soils (such as sandy soil, gravel soil, and graphitized scorched soil), due to the high hardness of the soil itself, high compaction, or the presence of special high-hardness abrasive particles in the soil, conventional metal presses highly fragile
