Problems solved by technology
[0003] Now the Luoyang shovel made of cast iron is easy to rust. With the advancement of science, the soil brought out by the Luoyang shovel needs to be tested, which will affect the test results of the soil; the Luoyang shovel is mainly used for fine excavation, and it is easy to touch ancient objects. Excellent materials will cause irreparable damage to ancient objects; the existing Luoyang shovel is very heavy, and it is difficult for scientists to control the force when using it, so they cannot effectively feel the changes in soil quality during the excavation process

Abstract
The invention discloses a portable Luoyang spade. A spade handle and a spade body are integrally made of one material which is composed of, by weight, 15%-25% of PVC (polyvinyl chloride), 5%-8% of cobalt, 2%-6% of chromium, 2%-10% of niobium, smaller than 2% of total content of carbon and oxygen and the balance aluminum. The portable Luoyang spade is lightweight, easy to control in use and convenient for archaeologists to feel changes of soil textures during excavation. In addition, due to special material quality, the portable Luoyang spade is less prone to corrode and avoids influences on soil constituents, and since the portable Luoyang spade is high in ductility, damage degree of antiques in contact with the spade during excavation is greatly lowered.
Description
technical field [0001] The present invention relates to archaeological material. Background technique [0002] Luoyang shovel, also known as Tan shovel, is an archaeological tool, which is a semi-cylindrical iron shovel. A long white wax rod with a handle. When in use, poke the ground vertically downwards, and the depth can be more than 20 meters. The semi-cylindrical shovel can be used to bring out the underground soil, and gradually dig a deep well with a diameter of about ten centimeters to detect the soil quality of the underground soil layer. , to know whether there are ancient tombs underground. The common Luoyang shovel clamp is only 2 inches wide, and the width is U-shaped semicircle. Although the long-handled Luoyang shovel on the upper part of the shovel looks like a semicircle, the shape is neither round nor flat. The most important thing is to create the arc during molding. It is 20 to 40 centimeters long and 5 to 20 centimeters in diameter. After installing a...
