Description

Technical Field

[0001] The invention belongs to the technical field of fruit sorting, and in particular relates to automatic fruit sorting equipment. Background Art

[0002] At present, fruits need to be sorted after being picked, and fruits of different sizes need to be classified, and then sold according to the size of the fruit. At present, there are two main methods for fruit size classification: manual sorting and machine sorting. Among them, manual sorting is labor-intensive and has low sorting efficiency. The machine sorting method usually has insufficient sorting accuracy, which easily causes the fruit to block the sorting equipment during the sorting process, resulting in low sorting efficiency.

[0003] Therefore, there is an urgent need to provide a fruit automatic sorting device with high sorting efficiency and high degree of automation. Summary of the invention

[0004] In view of the above-mentioned shortcomings, the object of the present invention is to provide an automatic fruit sorting device, which solves the problem that the sorting device in the prior art is easily blocked during sorting and has low sorting efficiency.

[0005] To achieve the above purpose, the technical solution provided by the present invention is:

[0006] An automatic fruit sorting device comprises a conveying mechanism and a sorting mechanism, wherein the sorting mechanism is arranged downstream of the conveying mechanism, and the sorting mechanism comprises a rotatably arranged sorting cylinder, a plurality of sorting areas are arranged on the sorting cylinder, and a plurality of through holes are evenly arranged on each sorting area. A spiral guide ring is arranged in the sorting cylinder to guide the fruit rotationally, and a sorting outlet is correspondingly arranged below each sorting area.

[0007] With the above structural design, automatic loading and sorting can be achieved through the cooperation of the conveying mechanism and the sorting mechanism, and the sorting mechanism adopts a rotating sorting cylinder, and a plurality of sorting areas corresponding to fruits of different sizes are arranged in the sorting cylinder, and a spiral guide ring is arranged in the sorting cylinder to guide or flip the fed fruits to prevent the fruits from being blocked, thereby improving the sorting effect and efficiency.

[0008] Preferably, the conveying mechanism comprises a frame, a conveyor belt is provided on the frame, the conveyor belt is driven by conveyor rollers provided at both ends, and the conveyor rollers are driven by a first driving motor provided on the frame.

[0009] Preferably, partitions are evenly arranged on the conveyor belt, and baffles are arranged on both sides. The baffles adopt a chain structure, and a conveying chain is fixedly connected to the baffle. A conveying gear is provided on the conveying roller to mesh with the conveying chain, and the end of the conveying roller is connected to the first driving motor through the conveying gear and the conveying chain.

[0010] By adopting the above structural design, the conveyor belt is isolated into several areas, thereby ensuring smooth conveyance of fruits and ensuring uniformity of delivery into the sorting drum, which is not likely to cause blockage in the sorting drum.

[0011] Preferably, a guiding mechanism is provided between the conveying mechanism and the sorting mechanism, one end of the guiding mechanism is arranged below the conveyor belt, and the other end extends into the sorting barrel.

[0012] Preferably, the guiding mechanism comprises a material receiving portion which is inclined and provided with a baffle, the other end of which is connected to a funnel-shaped feeding portion, the lower end of which is a curved circular tube, and the free end of which extends into the sorting barrel.

[0013] With the above structural design, the guiding mechanism can not only connect the conveying mechanism and the sorting mechanism, but also play a buffering role due to the height difference between the top of the conveying mechanism and the sorting mechanism, thereby preventing the fruit from being damaged during the conveying and sorting process.

[0014] Preferably, the sorting mechanism also includes a mounting frame, on which a detachable mounting frame is provided, and both ends of the sorting cylinder are rotatably mounted on the mounting frame, and one end of the sorting cylinder is connected to a connecting shaft, and the other end of the connecting shaft is connected to a driving mechanism arranged on one side.

[0015] Preferably, a sliding groove is provided between the sorting areas, and an arc-shaped block is correspondingly provided on the mounting frame to cooperate with the sliding groove.

[0016] With the above structural design, the cooperation between the sliding groove and the arc block can play a supporting role, while not affecting the rotation of the sorting drum, thereby improving the stability of the rotation of the sorting drum.

[0017] Preferably, a guide groove is provided at the end of the separation cylinder, and a plurality of guide rollers are correspondingly provided on the installation frame for cooperative installation.

[0018] With the above-mentioned structural design, guide rollers and guide grooves are arranged at the end of the sorting drum. Because the end of the sorting drum will bear a certain gravity, in order to prevent the interference between the sorting drum and the mounting frame due to excessive gravity, which may cause the rotation to be obstructed, guide rollers are arranged for guidance to assist the rotation of the sorting drum.

[0019] Preferably, the driving mechanism includes a reducer and a second driving motor.

[0020] The above structural design makes it easy to adjust the rotation speed of the sorting drum.

[0021] Preferably, the apertures of the through holes on the sorting zone increase from upstream to downstream, and the sorting zones are provided in three numbers, including a small fruit sorting zone, a medium fruit sorting zone and a large fruit sorting zone.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. The sorting mechanism of the present invention adopts a rotating sorting cylinder, and multiple sorting areas corresponding to fruits of different sizes are arranged in the sorting cylinder. A spiral guide ring is arranged in the sorting cylinder to guide or flip the fed fruits to prevent the fruits from being blocked, thereby improving the sorting effect and efficiency;

[0024] 2. The present invention can realize automatic loading and sorting through the cooperation of the conveying mechanism and the sorting mechanism. Workers only need to place the fruits on the conveying mechanism to realize automatic loading and sorting, and then classify and collect them at the sorting outlet. The equipment has a high degree of automation, high sorting efficiency and high precision. BRIEF DESCRIPTION OF THE DRAWINGS
