Description

Technical Field

[0001] The utility model relates to the technical field of litchi screening equipment, in particular to a multi-stage sorting device for fresh litchi fruits. Background Art

[0002] In the field of litchi sorting technology, in order to improve sorting efficiency and accuracy, more flexible and efficient sorting solutions have been sought. In traditional sorting equipment, the design of the collection box is often fixed, that is, the internal separation area is preset and cannot be adjusted according to actual conditions.

[0003] There are several major issues with this fixed design of the collection bin. First, since litchis come in different sizes and shapes, the fixed separation area may not be able to accommodate all sizes of litchis, resulting in poor sorting. Some litchis may be too large or too small to be correctly sorted, reducing sorting accuracy.

[0004] Secondly, the fixed partition design limits the flexibility of sorting. The size distribution of litchi may change in different seasons or different litchi varieties. The fixed partition design cannot adapt to such changes, resulting in reduced efficiency of sorting equipment, and even the need to frequently replace or adjust equipment to accommodate litchis of different sizes.

[0005] In addition, the fixed partition design may also increase the manufacturing and maintenance costs of the equipment. Since multiple partition areas need to be preset, the structure and manufacturing process of the equipment may become more complicated. At the same time, if the partition area needs to be adjusted to accommodate litchis of different sizes, cumbersome mechanical adjustments or replacement of parts may be required, which increases the maintenance cost and difficulty of use of the equipment. In view of this, we propose a multi-stage sorting device for fresh litchi fruits. Utility Model Content

The bottom legs 20 of the adding funnel 2 are fixed to the top of the mounting bracket 1, thereby ensuring the stability of the funnel. The bottom of the unloading plate 21 extends to the left end of the screening shaft 52, thereby ensuring that the fresh lychees can accurately fall to the starting position of the inclined support frame 5, and the sorting process begins.

[0029] As a preferred embodiment of the present invention, a strip opening 10 is provided on the mounting bracket 1 for the feeding plate 21 of the adding funnel 2 to pass through. The strip opening 10 provided on the mounting bracket 1 allows the feeding plate 21 of the adding funnel 2 to pass through, and such a design ensures the stable installation of the adding funnel 2 without affecting the normal falling and sorting of fresh lychees.

[0030] As a preferred embodiment of the present invention, a first guide plate 53 is fixedly connected between two adjacent groups of screening shafts 52 at the top of the inclined support frame 5, and second guide plates 54 are fixedly connected on both sides of the first guide plate 53. The first guide plate 53 and the second guide plate 54 fixedly connected between two adjacent groups of screening shafts 52 at the top of the inclined support frame 5 can guide the fresh lychees to roll along a predetermined path, reduce deviation and blockage of the lychees during rolling, and improve sorting efficiency.

[0031] As a preferred embodiment of the present invention, a support rod 55 for supporting the right end of the screening shaft 52 is fixedly mounted on the oblique support frame 5. The support rod 55 is used to support the right end of the screening shaft 52, thereby ensuring the stability of the screening shaft 52.

[0032] As a preferred embodiment of the present invention, the collection area between two adjacent fixed partitions 30 is located directly below each group of screening shafts 52. This ensures that the lychees falling from the gaps between different screening shafts 52 can accurately fall into the corresponding collection area, thereby improving the accuracy and efficiency of sorting.

[0033] As a preferred embodiment of the present invention, a second collecting box 4 is provided at the right end of the inclined support frame 5 in the mounting bracket 1, and both the first collecting box 3 and the second collecting box 4 can be pulled out from the mounting bracket 1. The second collecting box 4 provided at the right end of the inclined support frame 5 in the mounting bracket 1 can collect the litchis that fall after passing through all the screening shafts 52. Both the first collecting box 3 and the second collecting box 4 can be pulled out from the mounting bracket 1, which facilitates the collection and processing of the sorted litchis.

[0034] As a preferred embodiment of the present invention, an end baffle 51 is fixedly installed at the left end of the top of the inclined support frame 5, and side baffles 50 are fixed at both sides, and the end baffle 51 is tightly fitted with the second guide plate 54. The end baffle 51 fixedly installed at the left end of the top of the inclined support frame 5 is tightly fitted with the second guide plate 54, preventing the fresh lychees from overflowing from the left side during the rolling process, thereby ensuring the normal operation and sorting efficiency of the sorting device.

[0035] When the multi-stage sorting device for fresh lychees of the utility model is used, first, the user adjusts the collection area in the first collection box 3 according to the size of the lychees to be screened. A plurality of fixed partitions 30 and movable partitions 31 are arranged in the first collection box 3, which divide the collection box into a plurality of collection areas. Each collection area is located directly below a group of screening shafts 52, and is used to collect lychees that fall from the gaps between the group of screening shafts 52. The design of the movable partitions 31 allows the division of the collection area to be flexibly adjusted to meet the collection needs of lychees of different sizes. After adjustment, the user adds the fresh lychees to the sorting device through the adding funnel 2. The design of the adding funnel 2 allows the lychees to slide smoothly to the starting position of the inclined support frame 5 to start the sorting process. Under the action of gravity, the lychees will roll down along the inclined support frame 5.

[0036] During the rolling process, the lychees will encounter a plurality of screening shafts 52 arranged in groups of two. The distance between each group of screening shafts 52 gradually increases from left to right, so that multi-level screening of fresh lychees can be achieved. Smaller lychees will fall through the gaps between the screening shafts 52, while larger lychees will continue to roll down until they encounter a gap that they can pass through.

[0037] After being screened by the screening shaft 52, the lychees will fall into the first collecting box 3 below. The lychees that have not fallen after passing through all the screening shafts 52 will roll to the right end of the inclined support frame 5 and be collected by the second collecting box 4. Both the first collecting box 3 and the second collecting box 4 can be drawn out of the mounting bracket 1, which facilitates the collection and processing of the sorted lychees.
