Description

Technical Field

[0001] The utility model belongs to the technical field of accessories of a fruit and vegetable weight sorting device and relates to a tray for a fruit and vegetable weight sorting device. Background Art

[0002] At present, with the continuous improvement of people's living standards in my country and the gradual formation of the concept of nutritious and healthy diet, domestic consumers' consumption demand for fruits and vegetables has shifted from "quantity" to "quality". However, due to the lack of post-harvest links, most fruits and vegetables are put on the market in their original state, with serious post-harvest loss and waste, and high quality but low price. Post-harvest commercial processing of fruits and vegetables can maintain product quality and increase product added value. Post-harvest commercial processing of fruits and vegetables refers to a series of measures taken to maintain and improve product quality and transform them from agricultural products into commodities, including cleaning, waxing and polishing, sterilization, preservation, grading, packaging and other links.

[0003] Among them, weighing and sorting machines are generally used for grading fruits and vegetables. For example, a Chinese patent document discloses a weighing and sorting machine and its sorting mechanism (application number: 202023055854.X). The weighing and sorting machine includes a sorting mechanism, which includes a frame; a conveyor bar, which slides horizontally and is connected to the frame; a tray, which is rotatably connected to the conveyor bar, and the rotation axis is horizontal and perpendicular to the sliding direction of the conveyor bar. The tray includes a connecting rod, a bracket, a disc body and a support rod. The connecting rod is horizontal and perpendicular to the conveying bar, and the two ends of the connecting rod are respectively rotated to connect the two conveying bars; there are two brackets, and the ends of the two brackets are rotatably sleeved on the outer periphery of a connecting rod, and at the same time, the two brackets do not interfere with each other; the disc body slides in the vertical direction to connect the bracket, and at the same time, a receiving groove is provided on the upper end surface of the disc body; there are two support rods, which correspond to the brackets one by one, and the two support rods are parallel to the connecting rod and connected to the end of the bracket away from the connecting rod, and both ends of the support rod extend out of the bracket; a receiving groove is provided at the upper end surface of the tray, and the receiving groove is used to accommodate agricultural products; a weighing assembly is fixedly connected to the frame, and the upper end surface is used to support the tray; and a driving assembly is connected to the frame for driving the tray to flip and reset; the lower end of the tray is used to slide against the weighing assembly; the weighing and sorting machine also includes a collecting mechanism connected to the frame, which is provided below the conveying bar and located on one side of the abutment for receiving and transporting agricultural products; and a conveying mechanism is connected to the frame for driving the conveying bar to move.

[0004] During use, the weighing and sorting machine has the following shortcomings: since the tray must be able to be supported by the weighing assembly, the tray body is movably connected to the connecting rod and the bracket respectively. In addition, the connecting rod and the bracket are respectively long round rods, so that the tray body, the connecting rod and the bracket are all in contact with the arc surface. During the transportation process, it is easy to cause the tray body to swing back and forth between the connecting rod and the bracket, causing the fruits and vegetables in the tray body to be in a bumpy state and causing damage to the surface of the fruits and vegetables. Summary of the Invention

[0005] The purpose of this utility model is to solve the above problems in the existing technology and propose a tray for a fruit and vegetable weight sorting device. The technical problem to be solved by this utility model is to ensure the accuracy of fruit and vegetable weighing while achieving the stability of the tray body transportation.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A tray for a fruit and vegetable weight sorting device comprises a bracket and a tray body arranged on the bracket and capable of being lifted relative to the bracket. The tray body is characterized in that a supporting portion is provided on the tray body, and the bracket comprises a connecting rod arranged on a side of the tray body close to the supporting portion, the connecting rod being located below the supporting portion, the length extension directions of the supporting portion and the connecting rod being consistent, and the lower surface of the supporting portion and the upper surface of the connecting rod being arranged in surface contact with each other.

[0008] The tray of the fruit and vegetable weight sorting device is configured so that the abutting surfaces of the tray body and the connecting rod are adjusted from arc-surface contact to surface-to-surface contact. During transportation, individual fruits and vegetables are placed on the tray body. Under the action of gravity, the lower surface of the abutting portion of the tray body and the upper surface of the connecting rod are in surface-to-surface contact. This not only improves the supporting performance but also increases the contact area between the two, thereby increasing the friction between the two. This allows the tray body to rest more stably on the connecting rod, preventing the tray body from shaking relative to the bracket. During weighing, the pressure sensor lifts the tray body, causing the tray body to rise relative to the bracket, i.e., there is no squeezing force between the tray body and the bracket. The pressure sensor detects the pressure of the tray body and the individual fruits and vegetables on the tray body, and obtains the weight of the individual fruits and vegetables through simple calculation, thereby ensuring the accuracy of fruit and vegetable weighing while achieving stability in tray transportation.

[0009] In the aforementioned fruit and vegetable weight sorting device tray, the connecting rod includes an inner rod and an outer sleeve that fits over the inner rod. The upper surface of the outer sleeve is arranged in surface-to-surface contact with the lower surface of the abutment portion. The outer sleeve increases the contact area between the connecting rod and the abutment surface, thereby enabling the bracket to better support and position the tray, thereby ensuring stable tray transportation.

[0010] In the aforementioned tray for a fruit and vegetable weight sorting device, the outer shell is square and cylindrical, and the lower surface of the abutment portion is flat. This structure allows the lower surface of the abutment portion to better abut against the upper surface of the outer shell, further increasing the contact area between the two, thereby enabling the bracket to better support and limit the tray body, thereby ensuring stable tray transportation.

[0011] In the aforementioned fruit and vegetable weight sorting device tray, the tray body, outer cover, and abutment portion are all elongated, with the abutment portion extending horizontally outward from the upper edge of the tray body's long side. The elongated tray body facilitates loading of fruits and vegetables such as sweet potatoes and cucumbers. Furthermore, the continuous strip shape of the outer cover and abutment portion increases the contact area between the two, ensuring more stable abutment between the tray body and outer cover.

[0012] In the above-mentioned tray for a fruit and vegetable weight sorting device, the outer shell is made of metal material. By making the outer shell of metal material, the structural strength of the outer shell itself can be improved, so that the outer shell can better support the tray body.

[0013] In the aforementioned tray for a fruit and vegetable weight sorting device, positioning rods are provided at each end of the tray body. The bracket further includes two pivoting arms, one of which is disposed beside each end of the tray body. The ends of the inner rod extend beyond the ends of the outer sleeve. One end of each pivoting arm is respectively mounted on the ends of the inner rod and connected to the ends of the outer sleeve. The other ends of each pivoting arm are respectively mounted on the two positioning rods, and the positioning rods are movable up and down relative to the pivoting arms. This structure can better achieve the lifting and resetting of the tray body relative to the bracket, allowing the outer sleeve to better support the tray body and achieve stable tray transportation.

[0014] In the aforementioned tray for a fruit and vegetable weight sorting device, the tray body further comprises a limiting portion, the outer sleeve is movably disposed up and down between the abutting portion and the limiting portion, and the rotating arm comprises a circular socket hole, the diameter of which is larger than the diameter of the positioning rod. Providing the socket hole on the rotating arm facilitates connection between the rotating arm and the positioning rod. Simultaneously, the diameter of the socket hole is set to be larger than the diameter of the positioning rod, and the outer sleeve is disposed between the abutting portion and the limiting portion, with a spacing therebetween. This allows the rotating arm and the positioning rod, as well as the outer sleeve and the limiting portion, to disengage when the tray body is lifted, thereby eliminating squeezing force between the tray body and the support, thereby ensuring accurate fruit and vegetable weighing.

[0015] In the aforementioned tray for a fruit and vegetable weight sorting device, the rotating arm has a connecting portion that is plugged into the end of the outer shell. Providing the connecting portion on the rotating arm not only facilitates the connection between the rotating arm and the outer shell, but also makes the connection between the rotating arm and the outer shell more stable, thereby improving the support stability of the tray body.

[0016] In the aforementioned fruit and vegetable weight sorting device, the opposing surfaces of the stopper and the outer shell are both flat. When the tray is flipped, the stopper prevents the tray from wobbling relative to the outer shell. By configuring the opposing surfaces of the stopper and the outer shell as flat, the stopper can better contact the outer shell and mitigate wobbling of the tray.

[0017] Compared with the existing technology, the advantages of the tray for the fruit and vegetable weight sorting device are: the tray for the fruit and vegetable weight sorting device adjusts the abutting surfaces of the tray body and the connecting rod from arc surface contact to surface-to-surface contact. At the same time, the connecting rod is configured as an inner rod and an outer sleeve sleeved on the inner rod, thereby increasing the contact area between the tray body and the connecting rod. The outer sleeve is made of metal material, so that the tray body can be more stably abutted against the connecting rod, avoiding the tray body from shaking relative to the bracket, ensuring the accuracy of fruit and vegetable weighing while achieving stability in tray transportation.

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] A tray for fruit and vegetable weight sorting device, referring to Figure 1-6, comprising a bracket 1 and a tray body 2 disposed on the bracket 1 and capable of being lifted relative to the bracket 1, the tray body 2 having a resting portion 2b, the bracket 1 including a connecting rod 1a disposed on a side of the tray body 2 near the resting portion 2b, the connecting rod 1a being located below the resting portion 2b, the tray body 2, the outer sleeve 1a2, and the resting portion 2b all being elongated, and the resting portion 2b being formed by horizontally extending outward from the upper edge of the long side of the tray body 2, the resting portion 2b and the connecting rod 1a both extending in the same direction in length, the lower surface of the resting portion 2b being in surface-to-surface contact with the upper surface of the connecting rod 1a, specifically, the connecting rod 1a including an inner rod 1a1 and an outer sleeve 1a2 sleeved over the inner rod 1a1, the upper surface of the outer sleeve 1a2 being in surface-to-surface contact with the lower surface of the resting portion 2b. Furthermore, depending on actual usage requirements, the connecting rod 1a may also employ an integrally formed inner rod 1a1 and outer sleeve 1a2.

[0027] In this embodiment, the outer sleeve 1a2 is preferably in the shape of a square cylinder, and the lower surface of the abutment portion 2b is flat; the outer sleeve 1a2 is preferably made of a metal material (such as an aluminum alloy); and the disk body 2 is preferably made of a plastic material, which not only facilitates the processing and manufacturing of the disk body 2 (injection molding can be used), but also keeps the quality of the disk body 2 within a reasonable range.

[0028] More specifically, refer to Figure 1-6 , positioning rods 3 are respectively provided at both ends of the disk body 2, and the bracket 1 also includes two rotating arms 1b respectively provided on the sides of the two ends of the disk body 2, and the two ends of the inner rod 1a1 respectively extend out of the two ends of the outer sleeve 1a2, one end of the two rotating arms 1b is respectively sleeved on the two end portions of the inner rod 1a1 and respectively connected to the end portions of the outer sleeve 1a2, and the other ends of the two rotating arms 1b are respectively sleeved on the two positioning rods 3, and the positioning rods 3 can move up and down relative to the rotating arms 1b; the disk body 2 also has a limiting portion 2c. In this embodiment, the opposing surfaces of the limiting portion 2c and the outer sleeve 1a2 are preferably flat, and the outer sleeve 1a2 is provided between the abutting portion 2b and the limiting portion 2c, and there is a distance between the outer sleeve 1a2 and the limiting portion 2c, and the rotating arm 1b has a circular hole-shaped sleeve hole 1b1, and the diameter of the sleeve hole 1b1 is larger than the diameter of the positioning rod 3.

[0029] In this embodiment, the rotating arm 1b preferably has a connecting portion 1b2, and the connecting portion 1b2 is plugged into the end of the outer sleeve 1a2.

[0030] The tray body 2 is long and has a storage groove 2a with an upward opening. The distance between the two opposite side walls of the storage groove 2a gradually decreases from top to bottom. The bottom wall and the wall surfaces of the two side walls of the storage groove 2a are both flat. When a single fruit or vegetable is placed in the storage groove 2a, the fruit or vegetable can be automatically stuck between the two side walls, reducing the shaking of the fruit and vegetable in the tray body 2 during transportation, thereby reducing damage to the surface of the fruit and vegetable; the side of the tray body 2 away from the outer sleeve 1a2 has a long buffer portion 2d, and the upper surface of the buffer portion 2d is flat and connected to the wall surface of the side wall of the storage groove 2a. By providing the buffer portion 2d, when the tray body 2 swings downward on one side, the fruit and vegetable can be cushioned when rolling from one side of the tray body 2, thereby reducing damage to the surface of the fruit and vegetable.

[0031] The following describes the working principle of the tray used in the fruit and vegetable weight sorting device:

[0032] When grading individual fruits and vegetables based on their weight, the individual fruits and vegetables are placed in the storage slot 2a of the tray 2. The tray 2 and the individual fruits and vegetables on it move along with the conveyor chain. When the tray 2 moves above the pressure sensor, the pressure sensor supports the tray 2, causing the abutment portion 2b of the tray 2 and the outer sleeve 1a2, as well as the rotating arm 1b and the positioning rod 3 to simultaneously disengage, resulting in no squeezing force between the tray 2 and the bracket 1. At this point, the pressure sensor detects the total weight of the tray 2 and the individual fruits and vegetables. The tray 2 is a prefabricated part, meaning that the weight of the tray 2 is a known constant. Therefore, the weight of the individual fruits and vegetables can be obtained through simple calculations to complete weighing.

[0033] The tray for the fruit and vegetable weight sorting device is designed by adjusting the abutting surfaces of the tray body 2 and the connecting rod 1a from arcuate contact to surface-to-surface contact. At the same time, the connecting rod 1a is configured as an inner rod 1a1 and an outer sleeve 1a2 sleeved on the inner rod 1a1, thereby increasing the contact area between the tray body 2 and the connecting rod 1a. The outer sleeve 1a2 is made of metal material, so that the tray body 2 can be more stably abutted against the connecting rod 1a, avoiding the shaking of the tray body 2 relative to the bracket 1, ensuring the accuracy of fruit and vegetable weighing while achieving stability in tray transportation.

[0034] In addition, based on the weighing results, if the fruits and vegetables on the tray 2 need to be output, the driving component on the sorting machine can drive the tray 2 to flip so that the fruits and vegetables on the tray 2 fall downward into the sorting basket, and the tray 2 is reset; if the fruits and vegetables on the tray 2 do not need to be output, the driving component does not move, and the tray 2 continues to move with the conveyor chain. This cycle is repeated to complete the weighing and sorting of fruits and vegetables.

[0035] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
