Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of organic fertilizer production, and specifically relates to an organic fertilizer detection device. BACKGROUND

[0002] Organic fertilizer is mainly obtained by using excrement and plant residues as raw materials and through fermentation, and has the characteristics of low raw material cost, long-lasting fertilizer effect, comprehensive nutrients and environmental friendliness. During the growth and manufacturing process of organic fertilizer, the indicators of the organic fertilizer need to be detected to ensure the fermentation efficiency and effect of the organic fertilizer, thereby ensuring the fertilizer effect and avoiding the impact on the land or crops after fertilization. The Chinese patent document CN214374623U discloses a detection device for detecting biological organic fertilizer. The detection device uses a detection box and a detection head on the detection mechanism, and the detection head can detect the organic fertilizer on the detection plate by moving the detection box up and down on the mounting rod. The control button and the operating rod on the control mechanism are used to control the entire detection device, improve the working efficiency of the detection device, and avoid the problem of low yield of good organic fertilizer due to inadequate detection. However, the detection device is used to detect the organic fertilizer transferred to the outside, and the organic fertilizer is easily affected by the external environment during the transfer, resulting in detection errors. In addition, the detection device needs to take samples of the organic fertilizer before detection, which not only complicates the process, but also cannot complete real-time detection of the fertilizer during the fermentation process, thereby failing to realize real-time and accurate control of the fermentation of the organic fertilizer, which easily leads to low fermentation efficiency or poor fertilizer effect. At the same time, after the detection head detects the organic fertilizer, manual cleaning of the detection head is required, otherwise the organic fertilizer may adhere to the surface of the detection head, which not only easily causes corrosion and aging of the detection head or the detection box, but also easily affects the accuracy of subsequent detection, which is not conducive to multiple and continuous detection of the organic fertilizer.
