Description
Technical Field
The invention belongs to the technical field of machinery, and relates to a nondestructive testing device for fruits and vegetables.
Background
As a device for measuring characteristics of fruits and vegetables without damaging them, there is a light-transmitting type measuring device for receiving light transmitted through fruits and vegetables and measuring absorbance absorbed inside the fruits and vegetables.
Because the gun head part of the measuring device can touch fruits and vegetables in the measuring process, a flexible outer cover is fixedly connected to the gun head part in order to avoid crushing the fruits and vegetables.
Because the outer cover is flexible, not only can the fruits and vegetables be prevented from being injured by the gun head, but also the fruits and vegetables can be contacted more stably, and the gap between the fruits and vegetables and the gun head can be eliminated as much as possible. Because the external light is prevented from entering the gun head, the more accurate measuring effect can be achieved.
However, the existing outer cover is usually directly buckled and connected at the gun head, so that the outer cover is easy to fall off after long-time use, and the stability of the outer cover is poor.
Chinese patent publication No. CN102959382a provides a "non-destructive measuring device for fruits and vegetables" which improves the accuracy of the measured value of the characteristics of fruits and vegetables by suppressing the influence of external light on the received light, and can measure light of a plurality of ranges of wavelengths at the same time. A nondestructive measurement device (A) for fruits and vegetables is provided with a light emitting unit (1) for irradiating light, a light receiving unit (2) for receiving diffused light, and a processing unit for calculating the transmitted light amount according to the diffused light detected by the light receiving unit and calculating the evaluation amount of fruits and vegetables according to a detection line, wherein the nondestructive measurement device comprises: a plurality of light sensors (61, 62) arranged on the surface of the substrate (6); a plurality of optical filters (51, 52) each disposed in the vicinity of each of the photosensors; a filter holding unit (5) that surrounds and holds the optical filters around the optical sensors, respectively; optical transmission cables (31, 32) for transmitting the diffused light detected by the light receiving unit to each optical filter; and a cable support part (4) which surrounds each end of the optical transmission cable and is connected with the filter holding part to hold each end of the optical transmission cable.
It can be seen that the outer cover in the above patent is directly buckled and connected to the gun head, and when the outer cover is used for a long time or the stress is too large, the outer cover is easy to fall off, and the problem of poor stability is also existed.
