Abstract

An efficient transplanting device having automatic seedling grasping and seedling replenishing functions, comprising a seedling grasping device, a seedling dropping device, and a seedling replenishing device. The seedling dropping device is used for dropping and transplanting seedlings; the seedling grasping device is used for transferring potted seedlings; inferior seedlings can be identified during seedling grasping and only high-quality seedlings are transferred; the seedling replenishing device is used for replenishing vacancies caused by inferior potted seedlings. Thus, the efficient transplanting device can replace manual work to remove inferior seedlings, and can also automatically perform seedling replenishing in the event of grasping failure or inferior seedlings, thereby avoiding feeding failure caused by empty seedling feeding cups. The seedling grasping mechanism can operate in a front-back direction and move up and down to flexibly grasp seedlings, and the transplanting rate and transplanting hole distance can be flexibly changed, thereby implementing multi-purpose use of a transplanter, enhancing the degree of automation of transplanting equipment, and improving the operating efficiency and quality of transplanting equipment.

An air inlet feed port (II-01) and an air inlet (II-02) are symmetrically and tangentially arranged in the middle of the cylindrical part (II-03). A cylindrical screen grading cavity (II-0604) coaxial with the cylindrical part (II-03) is provided in the cylindrical part (II-03). A grading impeller (II-0701) coaxial with the cylindrical part (II-03) is provided in the screen grading cavity (II-0604). Scattered ultrafine powder is subjected to primary grading by means of swirling airflow formed by the air inlet feed port (II-01) and the air inlet (II-02), a screen (II-0601) works in conjunction with the swirling airflow to perform secondary grading on the ultrafine powder having a particle size greater than the aperture of the screen (II-0601), and the grading impeller (II-0701) works in conjunction with high-speed swirling airflow to perform tertiary grading on the ultrafine powder. The system solves the problems of difficulty in ultrafine powder grading size control, low grading precision, low packaging efficiency, and poor compaction effect, thereby greatly improving the scattering, grading and packaging efficiency of peanut shell ultrafine powder.

Abstract

A preparation method for a copper or copper alloy material, and a refining agent for refining. The refining agent for refining the copper or copper alloy material is an alloy composed of a Cu element, an Re element, and an M element. The Re element is a rare earth element and the M element is an alkali metal element or an alkaline earth metal element. The refining agent is able produce a compound having a relatively small density with oxygen, phosphorus, or sulphur impurities, thereby achieving the goal of removing impurities. The contents of oxygen, phosphorus, and sulphur in a copper or copper alloy material refined using the present refining agent are all on the ppm scale. The invention also features low preparation costs.

Abstract

A 3D printing device and method based on centrifugal atomization, the device comprising a smelting system, a cabin (3) having a sealed cavity, a turntable (20), a guide sleeve (18), and a three-dimensional motion platform having a molten metal receiving unit (7), and a control unit for controlling the three-dimensional motion platform. Metal raw materials enter the sealed cavity after being smelted, and are atomized and thrown out in the circumferential direction due to the rotation of the turntable; the atomized molten metal passing through spray gaps (24) in the guide sleeve adheres to the receiving unit of the three-dimensional motion platform; and the control unit controls the movement of the three-dimensional motion platform to change the position where the receiving unit receives the molten metal to form workpieces of different shapes. According to the 3D printing method based on centrifugal atomization, during the entire printing process, the metal raw materials are directly melted and atomized, and then stacked and solidified, and only by controlling the solidification speed of the metal raw materials, the internal structure of the output workpieces can be more dense and uniform, thus improving the production efficiency.

Abstract

A tungsten-base alloy material and a preparation method therefor. The preparation method comprises: 1) evenly grinding composite powder containing tungsten and zirconium oxide, and then performing annealing treatment at the temperature of 700-1000°C to obtain powder A; and 2) grinding and then compression moulding the powder A, and then performing liquid-phase sintering to obtain a tungsten-base alloy blank so as to obtain the tungsten-base alloy material. According to the preparation method, the annealing treatment is performed on the powder after the first-time grinding, so that metal particles can become soft; then the powder is ground again, the problem that when single grinding is used and hardening is performed in the later period of material mixing, zirconium oxide particles cannot be effectively ground is solved, the grain size of the zirconium oxide particles is decreased, the degree of uniform distribution of the zirconium oxide particles in the powder is improved, thereby improving the tensile strength and hardness of the tungsten-base alloy which is obtained after sintering.

The present invention relates to a preparation method of tungsten alloy precursor composite powder, a ceramic aluminum oxide enhanced tungsten alloy and a preparation method thereof, and belongs to the technical field of a tungsten alloy. The preparation method of the tungsten alloy precursor composite powder in the present invention comprises: providing the mixed solution of ammonium metatungstate and soluble aluminum salt, adding oxalic acid into the mixed solution till pH is not larger than 1.5, a complex reaction is carried out, then removing the solvent to obtain the mixed powder. The preparation method of the present invention uses oxalic acid to adjust the pH after liquid-liquid mixing, hydrogen ions and tungstate ions in the solution will react to generate tungstate precipitate; oxalate ions and aluminum ions react to generate aluminum oxalate precipitate, due to the co-reaction and co-precipitation of tungstic acid and aluminum oxalate, serious segregation caused by the mass difference of tungsten atomic nucleuses and aluminum atomic nucleuses can be avoided, the uniformity degree of tungstic acid and aluminum oxalate in the obtained powder is improved, molecular mixing is achieved, and a raw material base is provided for improving high-temperature wear-resisting erosion-resistance performance of tungsten alloy.
