Description

Technical Field

[0001] The present invention relates to the technical field of carrot sorting devices, and in particular to a vibration picking device and method for sorting carrots. Background Art

[0002] The carrot sorting device is a mechanical equipment used to quickly and accurately grade and screen carrots. It aims to improve sorting efficiency, reduce labor costs, and ensure the stability and consistency of sorting quality to meet the requirements of different markets for carrot specifications and quality.

[0003] Patent application CN221753982U discloses a carrot screening machine. A feed conveyor mechanism is provided to transport carrots from a lower hopper. Driven by multiple conveyor belts, the carrots move from the feed conveyor mechanism toward a second rotating shaft. The gaps between the belts gradually increase in size from the feed conveyor mechanism toward the second rotating shaft. A combing mechanism operates to drop carrots arranged longitudinally onto a slide in ascending order and separate them with partitions. The slides are tilted, allowing the carrots to automatically slide into a loading bucket positioned between the two partitions under the influence of their own gravity. This patent application's high degree of automation significantly improves screening efficiency and achieves high screening accuracy.

[0004] The carrot screening machine in the above-mentioned prior art has the following defects in actual use:

[0005] The spacing between the multiple conveyor belts within the carrot screening machine could not be adjusted after design, resulting in poor adaptability in large-scale agricultural scenarios. For example, carrots from different planting bases vary in shape and size (diameter and length) due to differences in variety, soil, and climate. The screening machine with a fixed screening size was not compatible with carrot specifications from different regions. If the mesh size was too small, large carrots would get stuck, while if the mesh size was too large, small carrots would miss the screen. Furthermore, the machine was only suitable for a single carrot variety and could not handle crops with similar shapes but different sizes, limiting its scope of application.

[0006] Some of the dirt on the surface of carrots is easy to adhere to the screening machine during the screening process. The accumulation of dirt can easily change the screening channel size of the screening machine, causing the screening machine to be unable to screen carrots according to the pre-designed screening size, which has an adverse effect on the screening accuracy.

[0007] Therefore, the present invention provides a vibration sorting device and method for sorting carrots to solve the above problems. Summary of the Invention

[0008] In response to the deficiencies in the prior art, the present invention provides a vibrating selection device and method for carrot sorting, which solves the problem that the spacing between multiple conveyor belts in a carrot screening machine cannot be adjusted after the design is completed, resulting in poor adaptability in large-scale agricultural scenarios, and the screening machine with a fixed screening size cannot be compatible with carrot specifications in different regions. The screen holes are too small, causing large-sized carrots to get stuck, and the screen holes are too large, causing small-sized carrots to miss the screen. In addition, the device is only applicable to a single variety of carrots and cannot handle crops that are similar in shape to carrots but different in size, which limits the scope of application. Part of the soil on the surface of the carrots is easily attached to the screening machine during the screening process. The accumulation of soil is likely to change the size of the screening channel of the screening machine, thereby causing the screening machine to be unable to screen carrots according to the pre-designed screening size, thereby adversely affecting the screening accuracy.

[0025] Step 2: Carrots of different sizes pass through the first sorting mechanism, the second sorting mechanism, the third sorting mechanism, and the fourth sorting mechanism in sequence. Since the screening sizes of the carrots of the first sorting mechanism, the second sorting mechanism, the third sorting mechanism, and the fourth sorting mechanism increase in sequence, the carrots of increasing sizes pass through the first sorting mechanism, the second sorting mechanism, the third sorting mechanism, and the fourth sorting mechanism in sequence and fall onto the conveying plates at corresponding positions, and then slide through the conveying plates into the collection basket;

[0027] The present invention provides a vibration sorting device and method for carrot sorting. Compared with the prior art, it has the following advantages:

[0028] 1. A vibrating selection device and method for sorting carrots. The four sorting structures, through first, second, third, and fourth sorting mechanisms, can cooperate with each other to achieve rapid sorting and screening of carrots from small to large sizes. Furthermore, the first, second, third, and fourth sorting mechanisms can continuously rotate while screening the carrots, so that the carrots entering the sorting mechanisms at different positions can be continuously turned. The carrots in continuous motion can continuously adjust their posture relative to the surface of the sorting mechanism, thereby changing to different postures in a short period of time to adapt to the screening channels in each sorting mechanism, thereby avoiding the situation where the carrots are conveyed to the next sorting mechanism before being screened in time, thereby improving the sorting accuracy of the carrots and ensuring the consistency of sorting of carrots of the same specification.

[0029] 2. A vibrating selection device and method for carrot sorting. Multiple screening roller assemblies are provided in a first sorting mechanism. The gap between the first and second support rod units in each screening roller assembly serves as a screening channel. Carrots that meet the size of the screening channel can pass through the channel and be screened out, while carrots that do not meet the screening channel can quickly flow into the next sorting mechanism. Furthermore, the size of the gap between the first and second support rod units can be controlled by adjusting the height of a lifting ring. Furthermore, because the first and second uprights are in a V-shaped structure, as the lifting ring moves farther from a mounting seat, the first and second support rod units are pushed by the lifting ring and slide synchronously away from the mounting seat, thereby locking the minimum screening gap value between the first and second support rod units. Scale grooves provided on the first and second uprights enable precise adjustment of the position of the lifting ring, ensuring accurate adjustment of the distance between the first and second support rod units. Furthermore, the distance between the first and second support rod units in the screening roller assemblies at multiple positions can be quickly and synchronously adjusted by the screening size adjustment assembly, making the adjustment process faster and more convenient.

[0030] 3. A vibration picking device and method for sorting carrots, by arranging a first support rod unit, a second support rod unit and a first column and a second column, so that when the first support rod unit and the second support rod unit rotate to the uppermost position away from the conveying plate, the gap between the first support rod unit and the second support rod unit can form a screening channel for screening carrots, and when the first support rod unit and the second support rod unit rotate to the lowermost position close to the conveying plate, since the first support rod unit and the second support rod unit can freely slide along the first column and the second column toward the limit end cover, the gap between the first support rod unit and the second support rod unit is rapidly increased in a short time, on the one hand, the carrots stuck between the first support rod unit and the second support rod unit can be quickly released, avoiding the situation that the screening channel is blocked, and achieving the effect of automatically clearing the screening channel, on the other hand, the first support rod unit and the second support rod unit can be sent into the area where the multiple brush rollers are located, preparing for the subsequent cleaning of the first support rod unit and the second support rod unit.

[0031] 4. A vibration picking device and method for sorting carrots, wherein when the first support rod unit and the second support rod unit slide along the first column and the second column to the lowest position close to the limit end cover, the gear rings on the first support rod unit and the second support rod unit can mesh with the arc-shaped rack in turn, and the gear rings can be rotated rapidly under the action of the arc-shaped rack, and cooperate with the action of multiple brush rollers located just below the arc-shaped rack, and the first support rod unit and the second support rod unit can rotate rapidly relative to the bristles on the surface of the brush roller, and the dirt attached to the surfaces of the first support rod unit and the second support rod unit can be quickly cleaned, keeping the surfaces of the first support rod unit and the second support rod unit in a clean state at all times, avoiding dirt from adhering to the surfaces of the first support rod unit and the second support rod unit, changing the size of the screening channel between the first support rod unit and the second support rod unit, and ensuring the screening accuracy of the carrots.

[0058] A plurality of conveying plates 8 are sequentially arranged directly below the first screening chamber 3, the second screening chamber 4, the third screening chamber 5 and the fourth screening chamber 6, and are used to convey the screened carrots to the corresponding collection baskets. One end of each of the conveying plates 8 passes through the side wall of the screening box 2 and extends to the outside, and each conveying plate 8 forms a thirty-degree inclination with the horizontal plane, so as to quickly slide the screened carrots from the top of the conveying plate 8 into the collection basket. A protective plate is provided on one side of the outer wall of the screening box 2 by rotating through a hinge. When the protective plate is opened by rotating around the hinge, the adjusting wheels 94 in the first sorting mechanism 9, the second sorting mechanism 10, the third sorting mechanism 11 and the fourth sorting mechanism 12 can be adjusted.

The lifting ring 964 is slidably sleeved on the outer wall of the first column 962 or the second column 963, and the top of the lifting ring 964 contacts the bottom of the first support rod unit 967 or the second support rod unit 968 to keep the first support rod unit 967 or the second support rod unit 968 in contact with each other. Element 968 will not slide along the outer wall of the first column 962 or the second column 963 toward the mounting seat 961. The position of the lifting ring 964 on the surface of the first column 962 can be observed through the long strip notch. The two push rods 965 slide through the first mounting ring a3 and extend to the gap between the first mounting ring a3 and the first turntable 912, and the bottom ends of the two push rods 965 are respectively slidably set on the wedge surfaces of the No. 1 wedge block 9141 and the No. 2 wedge block 9142 at the corresponding positions, and the spring 966 is located between the hemispherical protrusion and the first mounting ring a3.

[0070] An embodiment of the present invention further provides a vibration sorting method for a vibration sorting device for sorting carrots, the method comprising the following steps:

[0071] Step 1: First, place the carrots to be screened on top of the vibrating screen 1, and the vibrating screen 1 drives the carrots to be transported towards the screening box 2;

[0072] A batch of carrots harvested from the planting base is put into the top of the vibrating screen 1 in batches. The vibrating screen 1 vibrates while conveying the carrots. Some of the soil attached to the surface of the carrots falls through the gaps in the screen, and then the carrots are first conveyed to the top of the first sorting mechanism 9.

[0073] When the carrots of the smallest size pass through the top of the first sorting mechanism 9, the servo motor 14 synchronously drives the gears 95 in the first sorting mechanism 9, the second sorting mechanism 10, the third sorting mechanism 11 and the fourth sorting mechanism 12 to rotate through the transmission chain 13, so that the first sorting mechanism 9, the second sorting mechanism 10, the third sorting mechanism 11 and the fourth sorting mechanism 12 rotate synchronously. The carrots are continuously moved by the driving force of the rotating first sorting mechanism 9, and the carrots of the smallest size fall into the gap between the two adjacent first support rod units 967 and the second support rod units 968, while the first support rod units 967 and the second support rod units 968 of the conveying plate 8 near the corresponding position in the first sorting mechanism 9 slide along the first column 962 and the second column 963 under the action of gravity. The block cannot slip off from the ends of the first column 962 and the second column 963. When the first support rod unit 967 and the second support rod unit 968 slide to a state where they are against the limit end cover, the toothed ring 9673 and the arc-shaped rack 911 at the corresponding position are engaged and connected, and the first support rod unit 967 and the second support rod unit 968 are completely immersed in the bristles on the surface of the brush roller 99. During the movement of the toothed ring 9673, it is driven by the arc-shaped rack 911 to rotate rapidly. During the rapid rotation of the first support rod unit 967 and the second support rod unit 968 relative to the bristles, the soil attached to the surface of the first support rod unit 967 and the second support rod unit 968 is swept off, and the soil falls through the mesh holes on the surface of the conveying plate 8, while the carrots slide through the inclined surface of the conveying plate 8 and fall into the collection basket at the corresponding position.

[0074] When the first support rod unit 967 and the second support rod unit 968 flip to the bottom near the conveying plate 8 and slide down along the outer wall of the first column 962, since the first column 962 and the second column 963 are designed in a "V" shape, the gap between the first support rod unit 967 and the second support rod unit 968 in the relative position gradually increases, and the carrots stuck in the gap between the first support rod unit 967 and the second support rod unit 968 can fall quickly. When the first support rod unit 967 and the second support rod unit 968 flip to the bottom near the inner partition of the screening box 2, they slide again to their original position near the limit end cover and can start screening carrots.

[0075] After being screened by the first sorting mechanism 9, the carrots pass through the partitions in sequence to the second sorting mechanism 10, the third sorting mechanism 11, and the fourth sorting mechanism 12. Carrots of different sizes are sequentially discharged into the collection baskets at the corresponding positions through the second sorting mechanism 10, the third sorting mechanism 11, and the fourth sorting mechanism 12 and the conveying plate 8 directly below the discharge chute 7.

[0076] When it is necessary to adjust the screening size of the first sorting mechanism 9 or the second sorting mechanism 10 or the third sorting mechanism 11 or the fourth sorting mechanism 12, first open the protective plate on one side of the screening box 2 around the hinge, then loosen the fastening bolts locking the adjusting wheel 94 and the second rotating ring b2, and manually rotate the adjusting wheel 94 in the first sorting mechanism 9 or the second sorting mechanism 10 or the third sorting mechanism 11 or the fourth sorting mechanism 12 clockwise in turn, and observe the position of the lifting ring 964 relative to the first column 962 through the long strip notch. As the lifting ring 964 slides one scale distance along the outer wall of the first column 962 toward the limit end cover, the distance between the adjacent first support rod units 967 and the second support rod units 968 increases by one millimeter, and decreases by one millimeter. When the top rod 965 reaches the preset position, the adjusting wheel 94 and the second rotating ring b2 are locked again with the fastening bolts.

[0077] Step 2: Carrots of different sizes pass through the first sorting mechanism 9, the second sorting mechanism 10, the third sorting mechanism 11, and the fourth sorting mechanism 12 in sequence. Since the first sorting mechanism 9, the second sorting mechanism 10, the third sorting mechanism 11, and the fourth sorting mechanism 12 screen carrots in increasing sizes, carrots of increasing sizes pass through the first sorting mechanism 9, the second sorting mechanism 10, the third sorting mechanism 11, and the fourth sorting mechanism 12 in sequence and fall onto the conveying plate 8 at the corresponding position, and then slide through the conveying plate 8 into the collection basket;

[0078] Step 3: For batches of carrots with obvious size differences in different planting bases, the screening specifications of the first sorting mechanism 9, the second sorting mechanism 10, the third sorting mechanism 11 and the fourth sorting mechanism 12 are adjusted according to the batch of carrots before screening to ensure that the screened carrots meet the sorting requirements.
