Embodiment Construction

[0040] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] Theoretical basis of the present invention:

[0042]After apples are infected by moldy heart disease bacteria, the molecules of the ventricular biological tissue will mutate, cavities, etc., and the absorption of the spectrum will change, resulting in different visible / near-infrared transmission spectrum curves. The test uses four 50W tungsten-halogen lamps The light source, Ocean Optics spectrometer USB2000+ and computer constructed an exploration platform for the spectral response characteristics of apple mold core disease. Using this platform, the transmission spectra of 500 apple samples were measured and cut along the stems. Among them, 27 different apples with similar diameters were obtained. The spectral image curve of the diseased fruit with mildew heart disease, such as figure 1 shown.

Abstract

The invention discloses a multi-station rapid automatic detecting and sorting apple mould core device and method. The device comprises a rotary table support, a circular base is arranged at the lowestend of the support, a stepping motor is arranged at the upper middle portion of the base, a secondary speed reducer is connected to the upper surface of the stepping motor, the secondary speed reducer and the support are connected into a pan-tilt, a pan-tilt support is connected to the exterior of the pan-tilt, the support is fixed to the base, the middle of the pan-tilt is connected to the rotary table through the pan-tilt support, detection positions are arranged on the rotary table, a station for installing an apply tray is arranged on each detection position, and an ultrasonic sensor is arranged at the upper surface of one end of each apply tray; a light source is arranged at the other end of each apply tray, and a photoelectric sensor is arranged below each apply tray. The whole rapid automatic detecting and sorting process for the apple mould core is achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural intelligent equipment, and in particular relates to an apple mold core disease equipment and method for rapid and automatic detection and sorting. Background technique [0002] Apple moldy heart disease, also known as heart rot, is the main disease that endangers the internal quality of apples. In recent years, the incidence rate of red Fuji apples is generally high, the general incidence rate is about 21%, especially the incidence rate of bagged red Fuji apples is as high as 43.5% -79.5%. [0003] The main period for the onset of apple moldy heart disease is the ripening and storage period of the fruit. When the onset spreads from the ventricle, it has no obvious characteristics on the outside. It is difficult to identify the disease during fruit picking and sorting. It often develops and rots during storage, which seriously affects the interests of fruit merchants and consumers. On the ot...
