Description

Technical Field

[0001] The utility model belongs to the technical field of fruit sorting trays, and particularly relates to a tray mechanism for a fruit sorter. Background Technique

[0002] In the existing fruit production chain, multiple nodes such as picking, sorting, storage, and sales are closely linked, and each environment causes damage to fruits. Among them, the sorting link causes relatively serious damage to fruits. Traditional sorting methods generally place fruits on a production line for transportation and are sorted manually. During the transportation process, fruits are prone to rolling, bumping, abrasion, etc., resulting in a high fruit damage rate.

[0003] With the investment of intelligent sorting equipment, for round or nearly round fruits such as apples, chain transmission is adopted. The fruits are placed on the fruit trays of the chain conveyor belt, and the fruit grading is realized by tilting. In order to prevent the fruits from rolling and falling in the trays, Chinese Patent CN202222695076.3 discloses a special fruit sorting tray. By arranging petal-shaped elastic holding plates on the top surface of the tray for limiting the fruits, the fruits can be prevented from rolling in the tray. However, in this way, small fruits will be stuck between the elastic holding plates, making it impossible to separate the fruits during tilting sorting. Moreover, during tilting sorting, there is a lack of guidance, which easily causes the fruits to deviate from the direction when flipping and rolling, resulting in the fruits falling and being bruised. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages of difficult separation during flipping and falling during the sorting process in the prior art, and to propose a tray mechanism for a fruit sorter.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] Design a tray mechanism for a fruit sorter, including a flipping connecting seat. A weighing platform is fixed on the top of the flipping connecting seat. A tray rack is fixed on the top of the weighing platform. The tray rack is in a cylindrical structure. A flexible tray in a bowl shape is fixedly arranged in the top opening of the tray rack. Limiting claws are arranged on the circumference of the top of the tray rack. Elastic sheets for elastically supporting the limiting claws are fixed on the backs of the limiting claws, and the bottoms of the elastic sheets are fixed on the top of the tray rack.

[0007] Further, the flexible tray is a flexible part made of rubber or silica gel. A plurality of buffer grooves are penetrated through the center line of the flexible tray, and the buffer grooves evenly divide the middle part of the flexible tray into petal-shaped supporting parts.

[0008] Further, the limiting claws are sponge columns, and a supporting part extending outwards is arranged at the top.

[0009] Further, the limiting claws are composed of two short limiting claws and two long limiting claws, and the two short limiting claws are symmetrically arranged on one side where the tray rack flips.

[0010] Further, the bottom of the elastic sheet is a fixed seat, and an elastic buffer area is provided below the limiting claws where the elastic sheet is located. The elastic buffer area bends outward in an arch shape.

[0011] A tray mechanism for a fruit sorter proposed by the present utility model has the following beneficial effects:

[0012] (1) The present utility model adopts a flexible tray with a bowl-shaped structure and a buffer groove is opened inside, which can play a good buffering role for the fruits falling into the tray rack, protect the fruits from being damaged during transportation, and has a simple structure and is easy to manufacture.

[0013] (2) By circumferentially arranging limiting claws on the top of the tray rack, on the one hand, the problem of the flexible tray dropping fruits during transfer and storage can be solved. On the other hand, during flipping and sorting, the limiting claws play a guiding role, enabling the fruits to roll along the direction of the limiting claws and not "deviate" and fall, which can reduce the fruit loss rate during fruit sorting.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0023] Now, in conjunction with the accompanying drawings of the specification, the structural features of the present utility model will be described in detail.

[0024] See Figures 1-4 , a tray mechanism for a fruit sorting machine, including a flipping connection seat 1. A weighing platform 11 is fixed on the top of the flipping connection seat 1. A tray rack 2 is fixed on the top of the weighing platform 11. The tray rack 2 is in a cylindrical structure. A flexible tray 3 in a bowl shape is fixedly arranged in the top opening of the tray rack 2. The flexible tray 3 is a flexible member made of rubber or silica gel. A plurality of buffer grooves 31 penetrate through the center line of the flexible tray 3. The buffer grooves 31 evenly divide the middle part of the flexible tray 3 into petal-shaped supporting parts. When fruits fall into the flexible tray 3, the petal-shaped supporting parts will play a buffering role for the fruits, providing good protection for the fruits during the transportation and sorting process, and preventing them from being damaged by rolling, bumping, and abrasion during the transportation process. Moreover, the structure of the flexible tray 3 is simple and easy to manufacture, which can reduce the manufacturing cost of the tray mechanism.

[0025] In order to prevent fruits from falling during transportation, limit claws 4 are circumferentially provided at the top of the tray rack 2. An elastic sheet 5 for elastically supporting the limit claws 4 is fixedly provided on the back of the limit claws 4. The limit claws 4 are sponge columns, and a supporting portion 43 extending outwards is provided at the top. The limit claws 4 with a soft sponge structure will not cause damage to the falling fruits. The supporting portion 43 at the top makes it easier for the fruits to fall into the flexible tray 3. The bottom of the elastic sheet 5 is a fixed seat 51. An elastic buffer zone 52 is provided below the limit claws 4. The elastic buffer zone 52 bends outwards in an arch shape. The bottom of the elastic sheet 5 is fixed to the top of the tray rack 2. The limit claws 4 are composed of two limit short claws 41 and two limit long claws 42. The two limit short claws 41 are symmetrically arranged on the side where the tray rack 2 is flipped. Since the limit claws 4 can bend and expand in all directions, if the falling fruits have a larger diameter, they will also be clamped within the limit claws 4 and will not fall. By providing the limit claws 4, it is realized that even large fruits will not fall during transportation. And during the flipping and sorting process, due to the limit claws 4 being pressed down by the fruits, the elastic sheet 5 bends downwards, thereby expanding the opening amount of the limit claws 4. The limit claws 4 lose the clamping force on the fruits, enabling the fruits to easily leave the flexible tray 3 without being restricted by the limit claws 4, realizing easy separation of the fruits during flipping.

[0026] The tray mechanism for a fruit sorter of the present utility model has a simple structure and is convenient for flipping and sorting fruits. On the one hand, by adopting the flexible tray 3 with a bowl-shaped structure, it protects the fruits from being damaged during transportation. On the other hand, during the sorting process, by circumferentially providing limit claws 4 at the top of the tray rack 2, it can prevent the fruits from falling out of the flexible tray 3. During the flipping and sorting, the limit claws 4 play a guiding role, enabling the fruits to roll along the direction of the limit claws 4 and not "deviate" and fall, thereby reducing the fruit loss rate during fruit sorting.

[0027] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
