Abstract
Description
Technical Field
[0001] This utility model relates to the field of support trays, and in particular to a support tray for fruit testing and conveying. Background Technology
[0002] Fruit is an edible plant fruit that contains rich vitamins and other nutrients. Common fruits include apples, pears, oranges, tangerines, and bananas. To ensure that the fruit supplied to people is intact, fruits undergo certain tests before being sold to reduce the probability of people buying spoiled fruit.
[0003] Currently, sugar content testing for small, round fruits such as apples, oranges, and tangerines (hereinafter referred to as fruits) requires a sugar content detection device. Most commercially available fruit sugar content detection devices are assembly line type, mainly consisting of multiple conveyor belts, a spectral detection component, and fruit trays. In use, the fruit is placed on the tray, which is then placed on the conveyor belt. When the fruit enters the spectral detection component, its internal projected spectrum detects the fruit, thus obtaining the internal sugar content data. The fruit is then transported to the next sorting conveyor belt, awaiting manual unloading. Existing semi-circular trays, due to their fixed size, have poor clamping effect, making the fruit prone to shifting during transport; furthermore, they lack a rotating mechanism, requiring manual turning of the fruit during spectral detection, resulting in low efficiency. Utility Model Content
[0004] This application provides a support tray for fruit testing and conveying, which solves the technical problems of existing semi-circular trays, which have poor clamping effect due to their fixed size, making the fruit easy to shift during transportation; and lack of a rotating mechanism, requiring manual turning of the fruit during spectral detection, resulting in low efficiency.
[0005] The technical solution adopted in the embodiments of this application is as follows:
[0006] A fruit inspection and conveying support tray includes a base, a fruit-carrying tray for placing fruit, an elastic abutment device for adaptively abutting the fruit, and a support seat disposed at the bottom of the fruit-carrying tray; the support seat is mounted on the base; the fruit-carrying tray has a plurality of sets of elastic abutment devices arranged in a circumferential array in its inner cavity, the elastic abutment devices being configured to provide radial elastic clamping force to adapt to fruits of different sizes; the fruit-carrying tray has a plurality of sets of arc-shaped openings arranged in a circumferential array; each set of arc-shaped openings is rotatably connected to a rolling wheel, the rolling wheel part protruding from the inner surface of the fruit-carrying tray to form a rotational support point, so that the clamped fruit can rotate around a vertical axis under the flexible constraint of the elastic abutment device.
[0007] A further technical solution is as follows: the abutting device includes an arc-shaped baffle for abutting the fruit, a spring for cushioning the arc-shaped baffle, and a telescopic rod for limiting the spring; the spring is arranged around the telescopic rod; the telescopic end of the telescopic rod is connected to the arc-shaped baffle; the other end of the telescopic rod is connected to the inner cavity of the fruit tray.
[0008] A further technical solution is as follows: the abutment device further includes rubber pads; the arc-shaped baffle is provided with several sets of rubber pads arranged in an arc-shaped array.
[0009] A further technical solution is as follows: the fruit testing and conveying support tray also includes a bent handle; the support base is provided with two sets of the bent handles arranged symmetrically.
[0010] A further technical solution is as follows: a threaded rod is provided on the base; an internal thread groove adapted to the threaded rod is provided on the support seat; the threaded rod is threadedly connected in the internal thread groove.
[0011] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0012] 1. The design incorporates a base, fruit tray, elastic support device, and support seat. The elastic support device's spring and telescopic rod combination allows the arc-shaped baffle to float and extend radially. When fruits of different diameters are placed, the spring automatically adjusts its compression, driving the arc-shaped baffle to flexibly cover the fruit surface via rubber pads, achieving stable clamping across a wide range of sizes. Compared to fixed trays, this significantly improves production line compatibility and eliminates the tedious manual mold changes. The rolling wheels protrude from the inner surface of the fruit tray, forming discrete support points and creating a highly efficient rolling friction pair with the bottom of the fruit. The flexible constraint of the elastic support device allows the fruit to rotate smoothly under external force, while the transmitted vibration energy is insufficient to trigger rotation. This design overcomes the limitations of traditional clamping mechanisms on rotational function, significantly shortening the detection and flipping time and improving spectral scanning efficiency. The rubber pads disperse clamping pressure, effectively preventing mechanical damage to the fruit peel; the point contact mode of the rolling wheels significantly reduces the risk of fruit pulp compression; and the spring's buffering characteristics absorb longitudinal impact energy. This design is particularly suitable for fruits with delicate peels, comprehensively reducing post-harvest losses. The threaded rod and internal threaded groove allow for flexible height adjustment of the support base, quickly adapting to different testing positions; the bent handle provides an ergonomic handling interface, simplifying equipment maintenance. The elastic abutment device of the circumferential array forms a centripetal clamping force field, ensuring stable and centered positioning of the fruit; the arc-shaped opening layout of the rolling wheels maximizes the exposure of the fruit surface, ensuring the integrity of spectral detection. The overall structure fits the rhythm of automated production lines, achieving seamless coordination between conveying positioning and testing rotation. Attached Figure Description

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0020] A support tray for fruit testing and conveying, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a base 1, a fruit tray 2 for placing fruit, an elastic abutment device 3 for adaptively abutting the fruit, and a support 4 at the bottom of the fruit tray 2.

The elastic abutment devices 3 are configured to provide radial elastic clamping force to adapt to fruits of different sizes. Several sets of arc-shaped openings 21 arranged in a circular array are provided on the fruit tray 2. Each set of arc-shaped openings 21 is rotatably connected to a rolling wheel 5. The rolling wheel 5 protrudes from the inner surface of the fruit tray 2 to form a rotation support point, so that the clamped fruit can rotate around the vertical axis under the flexible constraint of the elastic abutment device 3.
[0021] The abutting device 3 includes an arc-shaped baffle 31 for abutting against the fruit, a spring 32 for buffering the arc-shaped baffle 31, and a telescopic rod 33 for limiting the spring 32; the spring 32 is arranged around the telescopic rod 33; the telescopic end of the telescopic rod 33 is connected to the arc-shaped baffle 31; the other end of the telescopic rod 33 is connected to the inner cavity of the fruit tray 2.
[0022] The abutment device 3 also includes rubber pads 34; several sets of rubber pads 34 arranged in an arc array are provided on the arc-shaped baffle 31.
[0023] The fruit testing and conveying support tray also includes a bent handle 6; two sets of bent handles 6 are symmetrically arranged on the support base 4.
[0024] A threaded rod 11 is provided on the base 1; an internal thread groove 41 adapted to the threaded rod 11 is provided on the support base 4; the threaded rod 11 is threadedly connected in the internal thread groove 41.
[0025] The support base 4 is threadedly connected to the inner threaded groove 41 of the base 1 via a threaded rod 11 to achieve height adjustment. The bottom of the fruit tray 2 is fixed to the support base 4, and its inner cavity has 6 sets of elastic abutment devices 3 arranged circumferentially. Each set includes an arc-shaped baffle 31, a spring 32 sleeved on the telescopic rod 33, and a rubber pad 34. One end of the telescopic rod 33 is fixed to the inner wall of the fruit tray 2, and the other end is connected to the arc-shaped baffle 31; the inner arc surface of the arc-shaped baffle 31 is embedded with 3 rows of rubber pads 34 to form a flexible contact surface. The side wall of the fruit tray 2 has 6 arc-shaped openings 21, and each opening is embedded with a rolling wheel 5, the rim of which protrudes 3mm from the inner surface of the fruit tray 2 to form a rotation support point. Bent handles 6 are symmetrically installed on both sides of the support base 4 for handling.
[0026] Operating procedures:
[0027] Placement stage: Place the fruit in the center of the fruit tray 2, apply downward pressure to cause the arc-shaped baffle 31 of the elastic abutment device 3 to contract radially, compress the spring 32 to generate an adaptive clamping force, and the rubber pad 34 adheres to the fruit surface to prevent slipping.
[0028] During the conveyor belt transport, the elastic abutment device 3 continuously applies radial restraint force to counteract the displacement caused by vibration, and the rolling wheel 5 makes point contact with the bottom of the fruit to avoid friction damage.

When fruits of different diameters are placed, the spring 32 automatically adjusts its compression, driving the arc-shaped baffle 31 to flexibly cover the fruit surface via the rubber pad 34, achieving stable clamping across a wide range of sizes. Compared to a fixed tray, this significantly improves production line compatibility and eliminates the tedious manual mold replacement. The rolling wheel 5 protrudes from the inner surface of the fruit tray 2, forming discrete support points and creating a highly efficient rolling friction pair with the bottom of the fruit. The flexible constraint of the elastic abutment device 3 allows the fruit to rotate smoothly under external force, while the transmitted vibration energy is insufficient to trigger rotation. This design overcomes the limitations of traditional clamping mechanisms on rotational function, significantly shortening the detection and flipping time and improving spectral scanning efficiency. The rubber pad 34 disperses clamping pressure, effectively preventing mechanical damage to the fruit peel; the point contact mode of the rolling wheel 5 significantly reduces the risk of fruit pulp compression; and the buffering characteristics of the spring 32 absorb longitudinal impact energy. Especially suitable for fruits with delicate skin, comprehensively reducing post-harvest loss rates. The cooperation between the threaded rod 11 and the internal threaded groove 41 allows for flexible height adjustment of the support base 4, quickly adapting to different testing positions; the bent handle 6 provides an ergonomic handling interface, simplifying equipment maintenance. The elastic abutment device 3 of the circumferential array forms a centripetal clamping force field, ensuring stable and centered positioning of the fruit; the arc-shaped opening 21 of the rolling wheel 5 maximizes the exposure of the fruit surface, ensuring the integrity of spectral detection. The overall structure fits the rhythm of automated production lines, achieving seamless coordination between conveying positioning and detection rotation.
