Embodiment 1

[0027] refer to figure 1 , the figure is a positioning automatic sampling device provided in this embodiment. In order to increase the degree of automation in the soil hydrolyzable nitrogen determination experiment and increase the sealing of the reaction tube in the experiment, the tube cover 30 and a series of other components are redesigned. .

[0028] Specifically, the positioning automatic sampling device includes a turntable 10, several reaction tube groups, a power unit 11,

[0029] Several reaction tube groups are arranged at intervals in a ring along the circumference of the turntable 10, and the power setting is configured to control the rotation of the turntable 10 along its axis. The reaction tube groups include a first reaction tube 21 and a second reaction tube connected to each other in a direction away from the center of the turntable 10. 22, the first reaction tube 21 and the second reaction tube 22 are provided with a cap 30 that can be selectively opened or...

Abstract

The invention relates to the field of experimental devices for measuring hydrolyzable nitrogen in soil, and more particularly to a positioning and automatic sample loading device. The device comprisesa turntable, a plurality of reaction tube sets, and a power apparatus. A plurality of reaction tube sets are arranged laterally spaced in an annular along the circumference of the turntable. The reaction tube set comprises a first reaction tube and a second reaction tube. The first reaction tube and the second reaction tube are arranged with a tube cover which can be optional to open or close. The automatic sample loading device further comprises a liquid adding device, a cover opening and closing apparatus and a titrator. The cover opening and closing apparatus is used to control the openingor the closing of the tube cover. The invention provides a positioning and automatic sample loading device, particularly provides an experimental device for measuring hydrolyzable nitrogen in soil with high degree of automation, wherein the reaction tube has good sealing performance and is easy to load sample or titrate. In addition, the device has high accuracy and can reduce experimental errors.

Description

technical field [0001] The invention relates to the field of soil hydrolyzable nitrogen determination test devices, in particular to a positioning automatic sampling device. Background technique [0002] Determination of soil hydrolyzable nitrogen refers to soil hydrolyzable nitrogen, also known as soil available nitrogen, including ammonium nitrogen, nitrate nitrogen, and easily decomposed and relatively simple amino acid nitrogen, amides, and easily hydrolyzable protein nitrogen in some organic matter. Determination methods include acid hydrolysis and alkali hydrolysis. [0003] In the prior art, steps such as sample addition and titration are required in the determination of soil hydrolyzable nitrogen, but through direct operation by personnel, ammonia leakage is prone to occur during operation, which affects the experimental environment and also affects the accuracy of the results. Contents of the invention [0004] The purpose of the present invention is to: in the p...
