Universal self-closing wear-resisting erosion-resisting soil sample press station

Abstract

The invention relates to a universal self-closing wear-resisting erosion-resisting soil sample press station; the resisting soil sample press station comprises a bottom plate, two first side plates, two second side plates and a cuboid top block, wherein two first trapezoid dovetail grooves and another two rectangular grooves are arranged on the bottom plate; the first trapezoid dovetail grooves are crossly symmetrical linear grooves of which openings are narrower than the bottom parts and the dip angle of oblique side is 20 degrees; the bottom parts of the first side plates are trapezoid wedges, and the matching gap between the first trapezoid dovetail groove and the trapezoid groove is lateral-sided 0.05 mm-0.07 mm; the side faces of the first side plates are further provided with two second trapezoid dovetail grooves of which dip angle of the oblique side is 15 degrees; the bottom parts of the second side plates are rectangular wedges adapted to the rectangular grooves, both ends of the side faces are provided with trapezoid wedges, and the matching gap between the second trapezoid dovetail groove and the trapezoid wedges is lateral-sided 0.05 mm-0.07 mm; the whole station is treated by cadmium plating; a neodymium iron boron magnetic block is further arranged on the bottom plate. The universal self-closing wear-resisting erosion-resisting soil sample press station is strong in university, self-closing, self-wear-resisting, and acid and alkali corrosion resisting.

Description

technical field [0001] The invention relates to the field of agricultural tools, in particular to a universal self-locking wear-resistant and anti-corrosion soil sample pressing machine station. 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 thi...

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
