Description

Technical Field

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

[0002] A carrot sorting device is a mechanical device used for quickly and accurately grading and screening carrots, aiming to improve sorting efficiency, reduce labor costs, and ensure the stability and consistency of sorting quality, so as to meet the requirements of different markets for carrot specifications and qualities.

[0003] Referring to a carrot screening machine disclosed in a patent application with a publication number of CN221753982U, a feeding and conveying mechanism is provided to convey the carrots coming down from the feeding hopper. The carrots move from the direction of the feeding and conveying mechanism to the direction of the second rotating shaft driven by multiple conveyor belts. The gap between the multiple conveyor belts gradually increases from the direction of the feeding and conveying mechanism to the direction of the second rotating shaft. Under the action of the combing mechanism, the longitudinally arranged carrots fall onto the slide plate in ascending order one by one and are separated by partitions. The slide plate is inclined, so the carrots automatically slide into the loading bucket arranged between the two partitions under the influence of their own gravity. This patent application has a high degree of automation, greatly improving the screening efficiency and having a relatively high screening accuracy.

[0004] The above-mentioned carrot screening machine in the prior art has the following defects in actual use: The spacing between multiple conveyor belts in the carrot screening machine cannot be adjusted after the design is completed, resulting in poor adaptability in large-scale agricultural scenarios. For example, due to differences in carrot varieties, soil, and climate in different planting bases, the morphological dimensions (diameter, length) of carrots are distributed differently. A screening machine with a fixed screening size cannot be compatible with carrot specifications in different regions. If the sieve holes are too small, large-sized carrots will get stuck, and if the sieve holes are too large, small-sized carrots will pass through the sieve, and it is only applicable to a single variety of carrots and cannot handle crops with similar shapes to carrots but different sizes, restricting the scope of application; Some soil on the surface of carrots is likely to adhere 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, resulting in the screening machine being unable to screen carrots according to the pre-designed screening size, having an adverse impact on the screening accuracy.

[0005] Therefore, the present invention proposes a vibration selection device and method for carrot sorting to solve the above problems. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides a vibration selection device and method for carrot sorting, which solves the problems 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. A screening machine with a fixed screening size cannot be compatible with carrot specifications in different regions. If the sieve holes are too small, large-sized carrots will get stuck, and if the sieve holes are too large, small-sized carrots will pass through the sieve. Moreover, it is only applicable to a single variety of carrots and cannot handle crops with similar shapes but different sizes from carrots, restricting the scope of application. Some soil on the surface of carrots is likely to adhere to the screening machine during the screening process, and the accumulation of soil easily changes the size of the screening channel of the screening machine, resulting in the screening machine being unable to screen carrots according to the pre-designed screening size, having an adverse impact on the screening accuracy.

On both sides of the tops of the two mounting seats, a first upright post and a second upright post are fixedly arranged respectively. The first upright post and the second upright post are distributed in a "V" shape structure. And at the ends of the first upright post and the second upright post far away from the mounting seat, a limiting end cover is fixedly arranged.

[0016] The present invention also discloses a vibration selection method for a carrot sorting vibration selection device. The method includes the following steps: Step 1: First, place the carrots to be screened on the top of the vibrating screen, and the vibrating screen drives the carrots to be conveyed towards the screening box; 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 turn. 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 turn, the carrots of small to large sizes pass through the first sorting mechanism, the second sorting mechanism, the third sorting mechanism and the fourth sorting mechanism in turn and fall on the conveying plate at the corresponding position, and slide into the collection basket through the conveying plate; Step 3: For batches of carrots with obvious size differences from different planting bases, the screening specifications of the first sorting mechanism, the second sorting mechanism, the third sorting mechanism and the fourth sorting mechanism are adjusted according to the batches of carrots before screening to ensure that the screened carrots meet the sorting requirements.

[0017] The present invention provides a vibration selection device and method for carrot sorting. Compared with the prior art, it has the following beneficial effects: 1. A vibrating selection device and method for sorting carrots. The first, second, third and fourth sorting mechanisms cooperate with each other to realize quick sorting and screening of carrots from small to large sizes in sequence. The first, second, third and fourth sorting mechanisms can rotate continuously while screening carrots, so that carrots entering the sorting mechanisms at different positions can be turned over continuously. The carrots in continuous motion can continuously adjust their postures relative to the surface of the sorting mechanisms, so that different postures can be changed in a short time to adapt to the screening channels in each sorting mechanism, so as to avoid the situation that the carrots are not screened in time but are transported to the next sorting mechanism, thereby improving the sorting accuracy of the carrots and ensuring the consistency of sorting of carrots of the same specification.

[0018] 2. A vibration selection device and method for carrot sorting. By arranging a plurality of screening roller assemblies in the first sorting mechanism and using the gap between the first support rod unit and the second support rod unit in each screening roller assembly as the 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. Moreover, the size of the gap between the first support rod unit and the second support rod unit can be controlled by adjusting the height of the lifting ring. And because the first column and the second column are in a "V" - shaped structure, when the lifting ring is farther away from the mounting seat, the first support rod unit and the second support rod unit are pushed by the lifting ring and slide synchronously away from the mounting seat, so that the minimum screening gap value between the first support rod unit and the second support rod unit is locked. And through the scale wire grooves arranged on the first column and the second column, the position of the lifting ring can be accurately adjusted to ensure the accuracy of the distance adjustment between the first support rod unit and the second support rod unit. Secondly, the distances between the first support rod unit and the second support rod unit in the screening roller assemblies at multiple positions can be synchronously and quickly adjusted by the screening size adjustment component, making the adjustment process faster and more convenient.

[0019] 3. A vibration selection device and method for carrot sorting. By arranging the first support rod unit, the second support rod unit, the first column and the second column, 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 towards the limit end cover, the gap between the first support rod unit and the second support rod unit rapidly increases in a short time. On the one hand, it can quickly release the carrots stuck between the first support rod unit and the second support rod unit, avoid the situation of the screening channel being blocked, and achieve the effect of automatically dredging 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 multiple brush rollers are located to prepare for cleaning the first support rod unit and the second support rod unit later.

[0020] 4. A vibration selection device and method for carrot sorting. When the first support rod unit and the second support rod unit slide along the first column and the second column to the lowermost position close to the limit end cover, the toothed rings on the first support rod unit and the second support rod unit can be engaged with the arc-shaped rack in sequence. Under the action of the arc-shaped rack, the toothed rings can rotate rapidly. Cooperating with the action of a plurality of brush rollers located directly below the arc-shaped rack, the first support rod unit and the second support rod unit can rotate rapidly relative to the bristles on the surface of the brush rollers. The soil 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 always in a clean state, avoiding the situation that soil adheres to the surfaces of the first support rod unit and the second support rod unit and changes the size of the screening channel between the first support rod unit and the second support rod unit, and ensuring the screening accuracy of carrots.

The top of the lifting ring 964 is in contact with the bottom of the first support rod unit 967 or the second support rod unit 968 to prevent the first support rod unit 967 or the second support rod unit 968 from sliding along the outer wall of the first upright post 962 or the second upright post 963 towards the mounting base 961. The position of the lifting ring 964 on the surface of the first upright post 962 can be observed through the long strip-shaped notch. Both top rods 965 slide through the first mounting ring a3 and extend into the gap between the first mounting ring a3 and the first turntable 912. And the bottom ends of the two top rods 965 are respectively slidably arranged on the wedge surfaces of the first wedge-shaped block 9141 and the second wedge-shaped block 9142 at corresponding positions. The spring 966 is located between the hemispherical convex block and the first mounting ring a3.

[0034] The embodiment of the present invention also provides a vibration selection method for a carrot sorting vibration selection device, and the method includes the following steps: Step 1: First, place the carrots to be screened on the top of the vibrating screen 1, and the vibrating screen 1 drives the carrots to be conveyed towards the screening box 2; A batch of carrots harvested from the planting base are batch-fed onto the top of the vibrating screen 1. While conveying the carrots, the vibrating screen 1 vibrates. Some of the soil attached to the surface of the carrots falls through the gaps of the screen mesh, and then the carrots are first conveyed to the top of the first sorting mechanism 9.

[0035] 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, and the carrots are continuously moved under the drive of the rotating first sorting mechanism 9. 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, and the first support rod units 967 and the second support rod units 968 of the conveying plate 8 at 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 blocking device 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 meshed 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.

[0036] 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 the original position near the limit end cover and can start screening carrots.

[0037] The carrots screened by the first sorting mechanism 9 pass through the partitions in turn to the second sorting mechanism 10, the third sorting mechanism 11 and the fourth sorting mechanism 12, and the carrots of different specifications and sizes pass 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 slot 7 in turn to be discharged into the collection basket at the corresponding position; When it is necessary to adjust the screening size of the first sorting mechanism 9, the second sorting mechanism 10, 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, and then loosen the fastening bolts of the locking adjustment wheel 94 and the second rotating ring b2. Manually rotate the adjustment wheel 94 in the first sorting mechanism 9, the second sorting mechanism 10, the third sorting mechanism 11, or the fourth sorting mechanism 12 clockwise in sequence, and observe the position of the lifting ring 964 relative to the first column 962 through the long strip-shaped notch. Since for each millimeter of sliding distance of the lifting ring 964 along the outer wall of the first column 962 towards the limit end cover, the distance between the adjacent first support rod unit 967 and the second support rod unit 968 increases by one millimeter, and vice versa decreases by one millimeter. When the ejector rod 965 reaches the preset position, lock the adjustment wheel 94 and the second rotating ring b2 again using the fastening bolts.

[0038] Step 2: Carrots of different specifications and 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 screening sizes of the first sorting mechanism 9, the second sorting mechanism 10, the third sorting mechanism 11, and the fourth sorting mechanism 12 for carrots increase in sequence, the carrots from smallest to largest in size 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 on the conveying plate 8 at the corresponding positions, and then slide into the collection basket through the conveying plate 8. Step 3: For batches of carrots with obvious size differences from different planting bases, before screening, adjust 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 according to the carrots in this batch to ensure that the screened carrots meet the sorting requirements.
