Technical Field

[0001] The utility model relates to the technical field of digestion devices, and particularly relates to a digestion device for measuring the content of soil organic carbon. Background Art

[0002] Soil organic matter is the main source of various nutrient elements in the soil, especially nitrogen and phosphorus. It can endow the soil with the ability of fertilizer retention and buffering, make the soil loose and form a structure, thus having the ability to improve the physical and chemical properties of the soil. It is one of the bases for soil classification. In addition, the biological characteristics of the soil will also change with the change of the quantity and quality of soil organic matter. Therefore, the content of organic matter is usually regarded as an important index for the level of soil fertility. The determination of soil organic matter can understand the dynamic change characteristics of organic matter, which is the basic condition for agricultural production management, realizing precision agriculture and ensuring the sustainable development of agriculture.

[0003] At present, in order to measure the content of soil organic carbon, a digestion instrument is used to digest and measure the soil. The related digestion instrument usually uses an experimental electric hot plate to heat and digest the soil sample in the test tube. However, during the heating process, the test tube and the hot plate are relatively stationary, and this heating and digestion method will cause the problem of uneven heating of the test tube, resulting in a very slow soil digestion efficiency.

[0004] Therefore, it is particularly important to design a digestion device for measuring the content of soil organic carbon to solve the above defects. Summary of the Utility Model

[0026] First, an inspection door 101 is provided at the bottom of the front side of the digestion box 1, and a power plug 102 is fixedly connected to the right side of the digestion box 1. The inspection door 101 is opened to inspect and maintain the rotating mechanism 4 inside the digestion box 1, and the digestion box 1 is powered by the power plug 102.

[0027] Then, the rotating mechanism 4 includes a driving motor 401 fixedly mounted on the bottom of the frame 3, a main shaft 402 is fixedly connected to the driving end of the driving motor 401 and located at the top of the frame 3, and the main shaft 402 is rotatably connected to the frame 3, and multiple groups of rotating shafts 403 are rotatably connected to the top of the frame 3 and located on the outside of the main shaft 402, and a driving gear 404 is fixedly mounted on the bottom end of the main shaft 402, and the multiple groups of rotating shafts 403 are meshed with the driving gear 404 through driven gears 405, and the main shaft 402 and the rotating shaft 403 are both rotatably connected to the partition 2, and the tops of the main shaft 402 and the rotating shaft 403 are fixed. A support 406 is fixedly connected, and a test tube fixing frame 5 is fixedly installed on the top of the support 406. When the soil is heated and digested, the test tube containing the soil is fixed on the support 406 through the test tube fixing frame 5, and then the driving motor 401 is started to drive the main shaft 402 to rotate, and under the transmission of the driving gear 404 and the driven gear 405, the multiple groups of rotating shafts 403 are driven to rotate together, thereby driving the multiple groups of test tubes to rotate. When the heating plate 6 is heated, the heat is discharged through the heat conducting plate 7, and the test tube is evenly heated during the rotation of the test tube, thereby improving the soil digestion efficiency.

[0028] Furthermore, the top of the test tube fixing frame 5 is fixedly connected with a first clamping plate 501, the left end of the first clamping plate 501 is hinged with a second clamping plate 502, a fixing stud 503 is movably installed between the first clamping plate 501 and the second clamping plate 502, the outer side of the fixing stud 503 is sleeved with a spring 504, the left end of the fixing stud 503 is threadedly connected with a locking screw sleeve 505, and the rear ends of the first clamping plate 501 and the second clamping plate 502 are sleeved with a rubber protective sleeve 506. When fixing the test tube, first turn the locking screw sleeve 506 to fix the test tube. 05 The first clamping plate 501 and the second clamping plate 502 are opened under the push of the spring 504, and then the test tube is placed between the first clamping plate 501 and the second clamping plate 502, and then the locking screw sleeve 505 is screwed back to clamp and fix the test tube using the first clamping plate 501 and the second clamping plate 502, so that the test tube can be quickly and conveniently fixed in the digestion box 1 for heating and digestion, which further improves the convenience of operation.

When heating and digesting the soil, the box cover 8 is covered, and the digestion condition of the soil can be observed through the transparent window 801. Before taking out the soil, the sealing cover 803 is first unscrewed, and the harmful gases generated by heating are discharged in advance through the exhaust pipe 802 to avoid harm to the staff.

[0031] In this embodiment, the implementation scenario is specifically as follows: when heating and digesting the soil, first rotate the locking nut 505 to open the first clamping plate 501 and the second clamping plate 502 under the pushing of the spring 504, then place the test tube between the first clamping plate 501 and the second clamping plate 502, and then screw back the locking nut 505 to clamp and fix the test tube by using the first clamping plate 501 and the second clamping plate 502. The test tube containing the soil is fixed on the support table 406, and then the driving motor 401 is started to drive the main shaft 402 to rotate. Driven by the driving gear 404 and the driven gear 405, a plurality of rotating shafts 403 are driven to rotate together, so as to drive a plurality of test tubes to rotate. When the heating plate 6 heats, the heat is exported through the heat conduction plate 7, and the test tubes are heated evenly during the rotation of the test tubes. The whole operation process is simple and convenient. Compared with the existing digestion device for measuring the organic carbon content of soil, the present utility model can improve the soil digestion efficiency and operation convenience through the design.
