Description

Technical Field

[0001] This utility model relates to the field of portable device technology, and in particular to a portable device for investigating the morphological characteristics of fruits. Background Technology

[0002] The pistil of a succulent plant develops through pollination and fertilization, with the participation of the ovary or other parts of the flower (such as the receptacle, calyx, etc.). A fruit generally consists of two parts: the pericarp and the seed. The pericarp can be further divided into the exocarp, mesocarp, and endocarp. Seeds play a role in dispersal and reproduction. Under natural conditions, some plants can produce fruit without pollination and fertilization; these fruits have no seeds or the seeds are infertile, hence they are called seedless fruits (such as seedless tangerines and bananas). Furthermore, ovaries that have not been pollinated and fertilized can form fruits due to certain stimuli (such as treatment with naphthaleneacetic acid or gibberellin), such as tomatoes and grapes, which are also seedless fruits. There are many types of fruits, and the structure of their pericarps varies. Specifically, this utility model relates to a portable device for investigating the phenotypic characteristics of fruits.

[0003] Chinese Patent No. CN208162080U discloses a portable device for investigating the morphological characteristics of fruits. The device includes a base, with support plates movably connected to both sides of the base via second limiting blocks. A display screen is embedded in the center of the base's front surface. A microcontroller is fixedly connected to the center of the base's interior. A weighing platform is fixedly connected to the top surface of the base. A set of electric telescopic rods is slidably connected to both sides of the weighing platform's upper surface via sliders. A servo motor is fixedly connected to the upper outer end of each electric telescopic rod, and the output end of the servo motor is rotatably connected to a vernier caliper via a coupling. Reflectors are fixedly connected to both sides of the electric telescopic rods via first limiting blocks. A feeding box is fixedly connected to the center of the top surface of the weighing platform via a column. This invention, by incorporating a vernier caliper, pressure sensor, sorting slot, colorimetric card, reflector, and support plate structure, offers advantages such as ease of use, high detection accuracy, and high efficiency.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the above-mentioned device can detect the size of the fruit through the structure of vernier calipers, but the above-mentioned device is prone to damaging the fruit skin during the process of detecting the fruit through the structure of vernier calipers.

[0032] The following is combined with Figure 1-5 The present invention will be described in further detail below.

[0033] Example 1

[0034] like Figure 1-Figure 5 As shown, in order to solve the existing problems, this utility model discloses a portable device for investigating the characteristics of fruit traits, including a base 1 and an elastic telescopic column 2 connected to its top. The top of the elastic telescopic column 2 is connected to a support limiting plate 3. The top of the base 1 is connected to a support bracket 4. The support bracket 4 is connected to a transmission component 5. The support bracket 4 is connected to a limiting component 6, which faces the support limiting plate 3.

[0035] The transmission component 5 includes a support plate 501 connected to the side of the support bracket 4. An electric telescopic rod 502 is connected to the support plate 501. A connecting plate 503 is connected to the output end of the electric telescopic rod 502. The connecting plate 503 is slidably connected to the support plate 501. A spring 504 is connected to the side of the connecting plate 503 away from the electric telescopic rod 502. A spring plate 505 is connected to the other end of the spring 504. A connector 508 is connected to the other end of the spring plate 505.

[0036] Furthermore, the connecting plate 503 is connected to a sliding column 506 on its side, and the spring plate 505 is provided with a sliding groove 507 on its side. The inner wall of the sliding groove 507 is slidably connected to the sliding column 506, and the sliding groove 507 is provided with scale lines on its side.

[0037] Specifically, the limiting component 6 includes a rotating connecting plate 601 connected to the support bracket 4. The rotating connecting plate 601 is rotatably connected to a plurality of rotating shafts. A rotating connecting rod 602 is fixedly connected to the top of the rotating shaft. A clamping plate 603 is rotatably connected to the other end of the rotating connecting rod 602. A clamping member 604 is connected to the side of the clamping plate 603. A pressure sensor 605 is connected to the side of the clamping plate 603.

[0038] Specifically, a gear 510 is connected to the bottom of the rotating shaft, and a rack 509 is slidably connected to the bottom of the rotating connecting plate 601. The rack 509 meshes with the gear 510 and is connected to the connecting member 508.

[0039] The specific working principle is as follows: This device can detect the fruit while protecting the fruit skin, and at the same time detect the firmness of the fruit to calculate the freshness of the fruit.

[0040] When using this device, the fruit is placed on the support limiting plate 3. At this time, the electric telescopic rod 502 retracts inward, thereby driving the connecting plate 503 to slide. The connecting plate 503 drives the spring 504, which in turn causes the spring plate 505 to slide. The structure of the spring plate 505 and the connecting piece 508 can drive the rack 509 to slide. The rack 509 meshes with the gear 510, thereby causing the rotating shaft to rotate. The rotating shaft drives the rotating connecting rod 602 to rotate, thereby causing the clamping plates 603 to move closer to each other, thus achieving the clamping effect of this device.

[0041] When the clamping member 604 contacts the side of the fruit, the rack 509 cannot slide, and the spring 504 is stretched. At this time, the stretching of the locking spring 504 can increase the clamping force of the clamping member 604, thereby achieving the effect of detecting the surface hardness of the fruit. The structure of the pressure sensor 605 can detect whether the surface of the fruit has been deformed, thereby determining the current hardness of the fruit. The combination of the sliding column 506 and the sliding groove 507 can intuitively display the current degree of clamping on the fruit.

[0042] Example 2

[0043] like Figure 1-Figure 5 As shown, in order to solve the existing problems in this embodiment, based on the same concept as the above embodiment one, the portable device for investigating fruit morphological characteristics further includes: the clamping plates 603 are symmetrically distributed on both sides of the rotating connecting plate 601, and the top of the support limiting plate 3 is provided with an arc-shaped groove, which is located at the center of the two clamping plates 603.

[0044] Furthermore, the rotating connecting plate 601 is provided with a plurality of rotating connecting rods 602 that are rotatably connected. The plurality of rotating connecting rods 602 are divided into two groups, and the rotating connecting rods 602 in the same group rotate synchronously.

[0045] Specifically, the rack 509 is provided with a sliding protrusion, and the rotating connecting plate 601 has a side limiting groove, which is slidably connected to the sliding protrusion.

[0046] The weight of the fruit can be detected by supporting the limiting plate 3 and the elastic telescopic column 2. When the fruit skin is dented, the sliding distance of the sliding column 506 is the corresponding hardness of the fruit. The scale line makes it easy for this device to read the value.

[0047] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
