Description

Technical Field

[0001] This utility model relates to the technical field of fruit and vegetable testing, and in particular to a special tray for testing pineapple fruits. Background Technology

[0002] Fruit and vegetable sorting machines typically detect the size, weight, appearance, and internal quality of fruits and vegetables to separate them into different grades. Existing technology includes a non-destructive spectral detection method. When fruits and vegetables placed on a detection cup are illuminated by a near-infrared light source, different internal components of the fruits and vegetables exhibit varying degrees of optical absorption and scattering at different wavelengths. Consequently, the internal spectrum changes with the mass fraction of these components. Utilizing this characteristic, the main components and their mass fraction in fruits and vegetables can be analyzed based on near-infrared spectral features, thereby sorting fruits and vegetables into different grades.

[0003] The testing cup has a detection hole running through it, located below the fruit or vegetable to be tested. Although there are light-blocking components around the detection hole, the light-blocking effect of the components is not good. This causes the beam of light emitted by the detection light source to scatter in the circumferential direction above the detection hole, affecting the accuracy of the fruit and vegetable testing results. Therefore, this needs to be improved. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies, such as the poor light-blocking effect of the light-blocking components around the detection hole, which causes the beam of light emitted by the detection light source to scatter in the circumferential direction above the detection hole, affecting the accuracy of fruit and vegetable detection results. It provides a new special tray for detecting pineapple-type fruits.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A special tray for detecting pineapple-type fruits includes a main body with a receiving groove and a support opening for placing fruits and vegetables. A flexible part is provided at the bottom of the receiving groove, and a first detection hole is provided through the bottom of the receiving groove. A second detection hole is provided on the flexible part, which is directly opposite to the first detection hole. The tray also includes a light-shielding member located on the upper surface of the flexible part and covering the second detection hole. A light-shielding area is provided through the light-shielding member, which is directly opposite to the second detection hole. The width of the light-shielding area gradually increases upward along the height direction. A deformation space is formed between the bottom of the flexible part and the bottom wall of the receiving groove.

[0006] The receiving groove and support opening facilitate the placement and positioning of the fruits and vegetables to be tested. The light-blocking area formed by the light-blocking component can block the first and second detection holes, preventing circumferential scattering of the detection light and improving the light focusing. This ensures that the detection light only penetrates through the fruits and vegetables to the area below the first detection hole, thereby improving the accuracy of the quality detection results. The flexible part and deformation space provide elastic support for the fruits and vegetables to be tested, avoiding damage caused by hard contact between the fruits and vegetables and the main body, which helps to maintain the condition of the fruits and vegetables to be tested.

[0007] Preferably, the special tray for detecting pineapple-type fruits described above includes a light-shielding component comprising a first baffle ring, a second baffle ring, and a third baffle ring distributed from the inside out. The upper end of the first baffle ring gradually slopes inward along the height direction. The upper end of the second baffle ring bends inward along the horizontal direction and blocks the first baffle ring. The upper end of the third baffle ring gradually slopes outward along the height direction. The second and third baffle rings are provided with a plurality of first deformation grooves spaced apart along the length direction of the light-shielding component. The second and third baffle rings are provided with clearance notches on both sides extending along the width direction of the light-shielding component. The clearance notches are used for the ends of the fruits and vegetables to be tested to pass through.

[0008] The upper end of the first baffle ring gradually tapers inward, making the upper end of the first baffle ring stand upright, which is convenient for supporting the fruits and vegetables to be tested. The second and third baffle rings provide further shielding and support for the fruits and vegetables to be tested. The notch makes it easier to place the fruits and vegetables to be tested more closely on the first, second and third baffle rings, further improving the light-blocking effect of the light-blocking component on the fruits and vegetables to be tested.

[0009] Preferably, in the above-described special tray for detecting pineapple-type fruits, the bottom of the light-shielding component is provided with a locking groove and a limiting groove communicating with the locking groove. A snap-fit ​​boss is provided on the inner side wall of the first detection hole, and a limiting block facing the center of the first detection hole is provided on the inner wall of the snap-fit ​​boss. The limiting block is inserted into the limiting groove and limits the horizontal direction of the light-shielding component. The snap-fit ​​boss is engaged with the locking groove and limits the height direction of the light-shielding component.

[0010] The insertion and engagement of the limiting block and the limiting groove, and the snap-fit ​​engagement of the snap-fit ​​boss and the locking groove, can limit and fix the light-shielding component to the main body in the horizontal and vertical directions, improving the ease and firmness of assembling the light-shielding component to the main body.

[0011] Preferably, in the above-described special tray for detecting pineapple-type fruits, the bottom of the light-shielding member is inserted into the first detection hole and the second detection hole. The light-shielding area includes a lower half area located in the first detection hole and the second detection hole and an upper half area located in the receiving groove. The lower half area is eccentrically arranged, and the center of the lower half area is located on one side of the receiving groove extending along the length direction from the center of the receiving groove.

[0012] The first detection hole, the second detection hole, and the lower half are eccentrically located at the bottom of the receiving tank. By controlling the position and size of the first detection hole, the second detection hole, and the lower half, it is possible to detect the location of fruits and vegetables to be tested, such as the half or more than half of the fruit or vegetable, further improving the accuracy of detection data such as water content and sugar content of fruits and vegetables such as pineapple and pineapple.

[0013] Preferably, in the above-mentioned special tray for detecting pineapple-type fruits, the inner sidewalls opposite to the receiving groove are provided with flexible retaining edges, which are distributed on both sides of the main body extending along the length direction.

[0014] The flexible edge can restrict the position of the fruits and vegetables to be tested on both sides along their length, improving the stability of the fruits and vegetables placed in the receiving tank during testing.

[0015] Preferably, in the above-mentioned special tray for detecting pineapple-type fruits, a reinforcing plate is provided on the inner wall of the receiving groove. The reinforcing plate is located inside the flexible edge and supports the flexible edge.

[0016] The reinforcement plate can support the flexible edge, further improving the stability of the flexible edge in securing the fruits and vegetables to be tested.

[0017] Preferably, the special tray for detecting pineapple fruits described above also includes a bracket. The inner side of the bracket is provided with a rotating shaft that cooperates with the main body. The bracket rotates around the rotating shaft in a direction that approaches or moves away from the bottom of the main body. A positioning block is provided on the main body. The main body, the bracket, and the positioning block form a first state and a second state. In the first state, the bracket is in contact with the bottom of the main body and supports the main body, and the positioning block is separated from the bracket. In the second state, the bracket rotates away from the main body and disengages from the bottom of the main body, and the inner side of the bracket is in contact with the positioning block.

[0018] The bracket can carry the main body and the fruits and vegetables to be tested on the conveyor line. When the bracket rotates away from the main body to the second state, there is a gap between the bracket and the bottom of the main body, which allows the main body and the bracket to be separated in the vertical direction without being stressed. Only the main body and the fruits to be tested inside it are weighed, which improves the versatility of use.

[0019] As a preferred embodiment, in the aforementioned special tray for detecting pineapple-type fruits, the lower surface of the light-shielding component is provided with a weight-reducing groove, and the weight-reducing groove is provided with a number of spaced reinforcing ribs.

[0020] By using weight-reducing grooves and reinforcing ribs, the weight of the light-blocking component can be reduced while its structural strength can be increased, making it easier to support the fruits and vegetables to be tested.

[0021] Preferably, in the above-described special tray for detecting pineapple-type fruits, the flexible part is provided with a plurality of snap-fit ​​blocks, and the inner wall of the receiving groove is provided with snap-fit ​​holes corresponding to the snap-fit ​​blocks. The flexible part is inserted into the receiving groove, and the snap-fit ​​blocks are inserted into the snap-fit ​​holes for snap-fit ​​engagement. The flexible part is provided with a plurality of second deformation grooves, one end of the second deformation groove is located at the second detection hole, and the other end of the second deformation groove extends along the length direction of the flexible part and is radially distributed.

[0022] The flexible part is installed on the inner wall of the receiving groove through the snap-fit ​​of snap-fit ​​blocks and snap-fit ​​holes, which has the advantages of simple structure and easy operation. When the fruits and vegetables to be tested are placed on the flexible part, the second deformation groove allows the flexible part to deform more freely, avoiding damage to the fruits and vegetables.

The upper end of the third baffle ring 53 gradually slopes outward along the height direction. The second baffle ring 52 and the third baffle ring 53 are provided with a plurality of first deformation grooves 7 spaced apart along the length direction of the light-shielding member 5. The second baffle ring 52 and the third baffle ring 53 are provided with clearance notches 71 on both sides extending along the width direction of the light-shielding member 5. The clearance notches 71 are used for the ends of the fruits and vegetables to be tested to pass through.

[0028] Preferably, the bottom of the light-shielding member 5 is provided with a locking groove 54 and a limiting groove 55 communicating with the locking groove 54. A snap-fit ​​boss 211 is provided on the inner side wall of the first detection hole 21. A limiting block 212 facing the center of the first detection hole 21 is provided on the inner wall of the snap-fit ​​boss 211. The limiting block 212 is inserted into the limiting groove 55 to limit the horizontal direction of the light-shielding member 5. The snap-fit ​​boss 211 is snap-fitted into the locking groove 54 to limit the height direction of the light-shielding member 5.

[0029] Preferably, the bottom of the light-shielding member 5 is inserted into the first detection hole 21 and the second detection hole 41. The light-shielding area 50 includes a lower half area 500 located in the first detection hole 21 and the second detection hole 41 and an upper half area 501 located in the receiving groove 2. The lower half area 500 is eccentrically arranged and the center of the lower half area 500 is located on one side of the receiving groove 2 extending along the length direction.

[0030] Preferably, the inner sidewalls of the receiving groove 2 are provided with flexible retaining edges 22, which are distributed on both sides of the main body 1 extending along the length direction.

[0031] Preferably, a reinforcing plate 23 is provided on the inner side wall of the receiving groove 2. The reinforcing plate 23 is located inside the flexible clamping edge 22 and supports the flexible clamping edge 22.

[0032] Preferably, the system also includes a bracket 8, the inner side of which is provided with a rotating shaft 81 that cooperates with the main body 1. The bracket 8 rotates around the rotating shaft 81 toward the bottom of the main body 1. A positioning block 11 is provided on the main body 1. The main body 1, the bracket 8, and the positioning block 11 form a first state and a second state. In the first state, the bracket 8 is in contact with the bottom of the main body 1 and supports the main body 1, and the positioning block 11 is separated from the bracket 8. In the second state, the bracket 8 rotates away from the main body 1 and disengages from the bottom of the main body 1, and the inner side of the bracket 8 is in contact with the positioning block 11.

[0033] like Figure 3 , Figure 6 , Figure 7 As shown, the bracket 8 is C-shaped and has multiple square plates integrally formed on it to improve the structural strength of the bracket 8. The upper and lower inner walls of the bracket 8 are integrally formed with rotating shafts 81. The bottom of the main body 1 is integrally formed with an extension platform. The extension platform has a rotating shaft hole that cooperates with the rotating shaft 81. The inner side of the bracket 8 is rotatably mounted on the extension platform through the cooperation of the rotating shaft 81 and the rotating shaft hole.

[0034] The bracket 8 has a through hole on its outer side for a long rod to pass through, which is used to cooperate with the transmission line. In the first state, the upper surface of the bracket 8 is in contact with the bottom of the main body 1, thereby allowing the main body 1 and the fruits and vegetables to be tested inside it to move on the transmission line via the bracket 8 and the long rod. When the bracket 8 rotates away from the main body 1 to the second state, there is a gap between the bracket 8 and the bottom of the main body 1, allowing the main body 1 and the bracket to detach vertically without being subjected to force, and only the main body 1 and the fruits to be tested inside it are weighed, thereby improving the versatility of use.

[0035] Preferably, the lower surface of the light-shielding member 5 is provided with a weight-reducing groove 56, and a plurality of spaced reinforcing ribs 561 are provided in the weight-reducing groove 56.

[0036] Preferably, the flexible part 4 is provided with a plurality of snap-fit ​​blocks 42, and the inner wall of the receiving groove 2 is provided with snap-fit ​​holes 24 corresponding to the snap-fit ​​blocks 42. The flexible part 4 is inserted into the receiving groove 2, and the snap-fit ​​blocks 42 are inserted into the snap-fit ​​holes 24 for snap-fit ​​engagement. The flexible part 4 is provided with a plurality of second deformation grooves 43, one end of the second deformation groove 43 is located at the second detection hole 41, and the other end of the second deformation groove 43 extends along the length direction of the flexible part 4 and is radially distributed.

[0037] Specifically, such as Figures 1-5 As shown, the flexible retaining edge 22 is integrally formed with the flexible part 4 or bonded to the flexible part 4. The flexible retaining edge 22 is located on both sides extending in the width direction of the flexible part 4, and extends along the length direction of the flexible part 4, with the flexible retaining edge 22 arched to form an outwardly protruding arc shape. The reinforcing plate 23 is integrally formed on the inner wall of the receiving groove 2, and the flexible retaining edge 22 is sleeved and fastened to the outside of the reinforcing plate 23. The reinforcing plate 23 extends into the flexible retaining edge 22 and supports the flexible retaining edge 22. In this embodiment, the flexible retaining edge 22 and the flexible part 4 are made of elastic rubber material.

[0038] The light-shielding component 5 includes a first retaining ring 51, a second retaining ring 52, a third retaining ring 53, and a base for cooperating with the main body 1. The base is hollow inside, and the outer side wall of the base is provided with a locking groove 54 and a limiting groove 55. There are two limiting grooves 55, which are symmetrically arranged on both sides of the base extending in the width direction. The number of limiting blocks 212 corresponds one-to-one with the limiting grooves 55. The base is engaged with the locking groove 54 and the snap-fit ​​boss 211. The limiting blocks 212 are detachably installed on the main body 1 through the engagement of the locking groove 54 and the limiting groove 55.

[0039] The lower part of the third retaining ring 53 is bent inward to form an L-shaped bend. The lower part of the L-shaped bend is integrally formed on the upper surface of the base and is lower than the upper surface of the flexible part 4. The upper part of the L-shaped bend extends outward along the height direction, thereby making the third retaining ring 53 open. The third retaining ring 53 is distributed between the flexible retaining edges 22, and the flexible retaining edges 22 fit and support the back of the third retaining ring 53.

[0040] The lower end of the first retaining ring 51 is integrally formed on the upper inner wall of the L-shaped bend on the third retaining ring 53. The first retaining ring 51 is rectangular and the upper end of the first retaining ring 51 is inclined inward along the height direction. The second retaining ring 52 is integrally formed on the inner wall of the third retaining ring 53 near the lower end and extends inward at an inward angle. The upper half of the second retaining ring 52 extends inward along the horizontal direction and covers the top of the first retaining ring 51.

[0041] The first retaining ring 51, the second retaining ring 52, and the third retaining ring 53 are made of rubber. The upper half of the second retaining ring 52 and the upper part of the L-shaped bend on the third retaining ring 53 are provided with a first deformation groove 7. The number of first deformation grooves 7 can be increased or decreased according to the size of the second retaining ring 52 and the third retaining ring 53.

[0042] More specifically, when it is necessary to test the fruits and vegetables to be tested, the fruits and vegetables to be tested are placed in the receiving groove 2. At this time, the lower part of the fruits and vegetables to be tested can be supported by the first retaining ring 51, the two sides of the fruits and vegetables to be tested can be clamped and limited by the flexible clamping edge 22, and the lower surface of the fruits and vegetables to be tested can be elastically supported by the flexible part 4, the deformation space 6, and the second deformation groove 43 to prevent the fruits and vegetables to be tested from being scratched or damaged. The supporting opening 3 and the clearance notch 71 not only allow the fruits and vegetables to be tested to be placed more stably and fit in the receiving groove 2, but also support and limit the front and rear ends of the fruits and vegetables to be tested.

[0043] The first retaining ring 51 is compressed by the weight of the fruit and vegetable to be tested, causing the first retaining ring 51 and the second retaining ring 52 to be pressed downwards by the fruit and vegetable to be tested. The second retaining ring 52 is slightly unfolded through the first deformation groove 7, and the upper half of the second retaining ring 52 tilts downwards with the pressure of the fruit and vegetable to be tested and extends into the interior of the first retaining ring 51, thereby making the fruit and vegetable to be tested tightly pressed against the first retaining ring 51. The second retaining ring 52 can block the gap between the fruit and vegetable to be tested and the first retaining ring 51; the third retaining ring 53 is connected by an L-shaped bend. The bend is directed toward the second detection hole 41, and the upper part of the L-shaped bend on the third retaining ring 53 is pressed against the upper surface of the bottom of the flexible part 4. This effectively blocks light from the first detection hole 21 and the second detection hole 41, so that the detection light can only pass through the fruit and vegetable being tested and reach below the first detection hole 21. The detection light is then transmitted to a receiving and analyzing device such as a collimating lens, preventing the beam emitted by the detection light source from scattering in the circumferential direction above the detection hole, thus improving the accuracy of the fruit and vegetable detection results.

[0044] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
