Description

Technical Field

[0001] The utility model relates to the technical field of rice nitrogen detection, and more specifically, to a device for detecting rice nitrogen nutrition. Background Art

[0002] Rice is one of the important food crops for mankind. It has a very long history of cultivation and consumption. Half of the world's population eats rice, mainly in Asia, southern Europe, tropical America and parts of Africa. During the cultivation process of rice, it is necessary to test the nitrogen content of rice to determine the nutritional value of rice.

[0003] Although the existing rice nitrogen nutrition detector is easy to carry and use during use, when the detector needs to be stored in a special box for carrying, the handle will occupy the storage space, making it inconvenient to fix the detector during storage, making the detector inconvenient to carry.

[0004] After searching, a Chinese patent with publication number CN218824217U discloses a portable rice nitrogen nutrition detector. The utility model can disassemble the handle and store it separately from the detector. When the detector is in use, the handle is inserted into the one-way slot through the card block, and then the movable card strip is pressed through the connecting block to fix the card block and the one-way slot. Then the user holds the handle and buckles his fingers into the slot handle, making the detector more convenient to hold. At the same time, the anti-slip cover on the surface of the handle increases the friction between the user's hand and the handle, making the user hold it more stably.

[0005] However, when the above detector is actually used, during the process of testing rice, when the rice leaves are placed in the detector, the handheld detector may shake, and the leaves may shake, resulting in errors in the detection of the detector and a wrong judgment of the nitrogen content of the rice.
