Description

Technical Field

[0001] The present invention relates to the technical field of sorting equipment, and in particular to an agricultural product sorting workstation with a transportation function. Background Art

[0002] During the harvesting and post-processing of agricultural products, especially for spherical or nearly spherical fruit and vegetable crops such as potatoes, apples, tomatoes, citrus fruits, onions, peaches, plums, beets, sweet potatoes, and persimmons, they often need to be sorted after harvesting for preliminary classification by volume. This volume-based grading not only facilitates subsequent quality screening but also improves the uniformity and value of the products, facilitating efficient and standardized marketing, standardized packaging, and logistics transportation. Therefore, volume sorting is a key step in the commercialization of agricultural products.

[0003] Currently, the volume sorting of agricultural products mostly relies on manual labor, with workers typically determining the size of fruits and vegetables individually by visual inspection or hand tools before sorting them into baskets. This sorting method presents numerous problems: First, the manual sorting process is tedious and labor-intensive, and prolonged work can easily lead to fatigue. Second, the sorting results are subject to subjective factors, making it difficult to maintain stable accuracy and consistency.

DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0022] like Figures 1 to 10 As shown, the agricultural product sorting workstation with transport functions includes: a frame 1, at least two conveyor mechanisms 2, and first storage boxes 3. The number of first storage boxes 3 matches the number of conveyor mechanisms 2, and is used to receive agricultural products output by different conveyor mechanisms 2, respectively, to achieve orderly storage after volume classification. The frame 1 constitutes the supporting framework of the entire workstation. The conveyor mechanisms 2 are sequentially installed on the frame 1 and arranged vertically from top to bottom, allowing agricultural products to pass through multiple conveyor mechanisms 2 from top to bottom with the assistance of gravity, achieving step-by-step sorting.

[0023] The conveying mechanism 2 comprises a housing 21, a conveying auger 22, a rotating shaft 23, a drive assembly 24, and an adjustment assembly 25. The housing 21 is a hollow structure, arranged horizontally and securely connected to the frame 1. It houses the conveying auger 22 and rotating shaft 23, forming a closed conveying channel to prevent agricultural products from falling or leaking during transportation. The conveying auger 22 and rotating shaft 23 are arranged parallel to the length of the housing 21 and are rotatably mounted within the housing 21 via bearings or support structures, ensuring rotational stability and coaxiality.

[0024] The driving assembly 24 is installed at one end of the shell 21 and is connected to the shaft ends of the conveying auger 22 and the rotating shaft 23. The driving assembly 24 can be a combination of a motor, a reduction mechanism, etc., and can simultaneously drive the conveying auger 22 and the rotating shaft 23 to rotate synchronously in different directions. Specifically, the conveying auger 22 rotates clockwise and the rotating shaft 23 rotates counterclockwise (or in opposite directions). Under the action of the relative motion generated by the rotation of the two, a synergistic force of clamping, rolling and conveying is formed, thereby achieving smooth pushing and sorting of agricultural products.

[0025] To adapt to produce of varying sizes, the adjustment assembly 25 is located outside the housing 21. Mechanically connected to the relative spacing between the conveyor auger 22 and the rotating shaft 23, the adjustment assembly 25 allows the gap between the conveyor auger 22 and the rotating shaft 23 to be adjusted based on actual usage, thereby controlling the critical screening size. For example, when the gap is reduced, only smaller produce is allowed to pass through; when the gap is increased, larger produce can also be dropped, achieving a flexible and adjustable screening range.

[0026] A rubber sleeve 231 is fitted around the outer side of the rotating shaft 23. Made of an elastic material, this sleeve effectively cushions the contact force between the agricultural products and the rotating shaft during rotation, preventing damage or breakage to the surface of the agricultural products and improving the adaptability and gentleness of the sorting process. The rubber sleeve 231 is also provided with multiple discharge ports 232, each of which is a through-hole or notch extending through the sleeve. When the sleeve rotates to a certain angle, the gap between the corresponding position and the conveying auger 22 increases, allowing sorted agricultural products to automatically discharge through this gap and fall into the corresponding first storage box 3 below.

[0027] In this embodiment, there are three conveyor mechanisms 2, arranged vertically in sequence, namely, the first conveyor mechanism, the second conveyor mechanism, and the third conveyor mechanism. The spacing between the conveying augers 22 and the rotating shafts 23 of the three conveyor mechanisms 2 decreases sequentially, so that all agricultural products entering the first conveyor mechanism undergo a first screening process. Agricultural products with a volume smaller than the gap between them fall into the second conveyor mechanism for further screening, and so on. Ultimately, agricultural products of different volume levels are discharged from the discharge sections 232 at different heights and fall into the corresponding first storage boxes 3.

[0028] In actual use, the user places the agricultural products to be sorted into the first conveying mechanism 2 on the top layer. After starting the drive assembly 24, the conveying auger 22 and the rotating shaft 23 rotate in different directions, respectively, exerting propulsion and rotational disturbance on the incoming agricultural products, causing them to gradually approach the gap between the two shafts as they advance. During transportation, smaller agricultural products, due to the effects of gravity and rotational disturbance, can smoothly fall through the gap between the conveying auger 22 and the rotating shaft 23 into the next level of the conveying mechanism. If the volume is still larger than the spacing of the next layer, it will continue to be transported downward for screening, and eventually fall into the first storage box 3 corresponding to the smallest gap it can pass through, achieving automated sorting according to its size. If the agricultural products are too large to pass through any of the gaps, they will be discharged from the top layer.

[0029] By adjusting the settings of component 25, the device can quickly adapt to the volume distribution of different spherical or quasi-spherical agricultural products (such as apples, potatoes, tomatoes, and citrus fruits), adapting to different sorting requirements and significantly improving sorting applicability and flexibility. The overall structure organically combines conveying and grading functions during the sorting process, saving the space and cost of independent conveying equipment while avoiding the repetitive labor of manual handling and sorting.

[0030] In this embodiment, the drive assembly 24 includes two arms 241, a motor 242, a first gear 243, a second gear 244, a first pulley 245, a second pulley 246, and a transmission belt 247. The two arms 241 are respectively arranged on one side of the conveying auger 22 and the rotating shaft 23. One end of the arm 241 is fixedly connected to the conveying auger 22, and the other end is fixedly connected to the rotating shaft 23. They are used to support the drive assembly on the overall structure and form a transmission installation foundation. The motor 242 is fixedly mounted on the beam or connecting portion between the two arms 241. Its output end passes through the two arms 241 and is rotatably connected to the two arms 241 via bearings or rotating shaft structures to ensure that the motor can operate stably and does not produce relative displacement during the driving process.

[0031] The output shaft of the motor 242 passes through the first gear 243 and the first pulley 245 in sequence. The first gear 243 is sleeved on the motor output shaft and fixedly connected thereto by a key connection or interference fit, ensuring that the first gear 243 can be driven to rotate synchronously when the motor is running; the first pulley 245 is also fixedly installed on the motor output shaft, preferably arranged at an adjacent position to the first gear 243, constituting the active end of the pulley transmission.

[0032] The second gear 244 is installed on the housing 21 of the conveying mechanism 2, specifically fixed on one end of the shaft coaxial with the conveying auger 22, and is fixedly connected to the shaft end of the conveying auger 22 by key connection or screw locking, so that when the second gear 244 rotates under the meshing drive, it can synchronously drive the conveying auger 22 to rotate around its own axis.

[0033] The second pulley 246 is installed on one end of the rotating shaft 23 and is fixedly connected to the rotating shaft 23 by means of screws or key connections; the transmission belt 247 is arranged in a ring manner between the first pulley 245 and the second pulley 246 to form a closed circular transmission structure. When the first pulley 245 rotates, the transmission belt 247 is driven to move, thereby driving the second pulley 246 to rotate synchronously, thereby realizing power transmission to the rotating shaft 23.

[0034] The first gear 243 is meshed with the second gear 244, that is, they mesh with each other in relative positions. The rotation of the motor 242 drives the first gear 243 to rotate, and then drives the second gear 244 to rotate, thereby realizing direct drive of the conveying auger 22; at the same time, the first pulley 245 drives the second pulley 246 to rotate via the transmission belt 247, and the second pulley 246 drives the rotating shaft 23 to rotate, thereby realizing synchronous drive of the rotating shaft 23.

[0035] In this embodiment, the adjustment assembly 25 includes a mounting frame 251 , an electric push rod 252 , a third gear 253 , and a fourth gear 254 ; The two support arms 241 are rotatably connected to the conveying auger 22 and the rotating shaft 23 respectively. Specifically, one end of the support arm 241 is connected to the shaft end of the conveying auger 22 through a rotating pair, and the other end is connected to the rotating shaft 23 through a bearing seat or a pin structure, so that the support arm 241 can drive the rotating shaft 23 to move along the trajectory while maintaining the stability of relative motion under the drive of the motor.

[0036] The shell 21 includes two side plates 211 and two sealing plates 212. The two side plates 211 are arranged opposite to each other and vertically connected to the two sealing plates 212 to form a conveying cavity structure with a closed space, which is used to accommodate and support core components such as the conveying auger 22 and the rotating shaft 23 to ensure structural rigidity and position stability during operation.

[0037] The sealing plate 212 is provided with a first guide groove 2121 and a second guide groove 2122. The first guide groove 2121 is a long groove structure extending in the horizontal direction, and the second guide groove 2122 is a curved groove structure arranged in an arc shape. The two serve as movable guide tracks for the rotating shaft 23 and the output end of the motor, respectively. The rotating shaft 23 passes through the first guide groove 2121 and is slidably connected to the first guide groove 2121, so that the rotating shaft 23 can move back and forth linearly along the direction of the guide groove under the drive of the support arm 241; the output end of the motor 242 passes through the second guide groove 2122 and is slidably connected to the second guide groove 2122, ensuring that the motor body can make relative displacement along the guide groove track during the adjustment process.

[0038] The fourth gear 254 is fixedly mounted on the output shaft of the motor 242 and is fixed thereto by a key connection or interference fit to ensure synchronous rotation; the conveying auger 22 passes through the sealing plate 212 and is rotatably connected to the sealing plate 212 by a bearing, forming an installation method that is compatible with support and rotation; the shaft end of the conveying auger 22 is connected to the third gear 253 by a rigid connection, so that the third gear 253 rotates synchronously when the auger rotates.

[0039] The mounting frame 251 is slidingly arranged along the direction of the slide rail matching with the closing plate 212, and the sliding pair connection mode enables it to move linearly along the set direction under the drive of the electric push rod 252; the inner surface of the mounting frame 251 is provided with a first latch 2511 engaged with the third gear 253 and a second latch 2512 engaged with the fourth gear 254, and the two sets of latches are arranged in different mounting areas, respectively, for locking or releasing the gears under different adjustment states; the electric push rod 252 is fixedly mounted on the closing plate 212 by screws or supports, and the output end is connected to the mounting frame 251, for driving the mounting frame 251 to move along the sliding direction, thereby realizing the adjustment of the meshing state between the latch and the gear.

[0040] When the distance between the conveying auger 22 and the rotating shaft 23 needs to be adjusted, the output end of the electric push rod 252 is retracted, and the electric push rod 252 pushes the mounting frame 251 to slide inward, driving the first latch 2511 to insert and engage with the third gear 253. Since the mounting frame 251 is structurally non-rotatable, the first latch 2511 axially locks the third gear 253, thereby keeping the conveying auger 22 in a stationary state. At the same time, the second latch 2512 disengages from the fourth gear 254, and the motor output end is freed from the mounting frame, becoming rotatable.

[0041] The motor 242 is then controlled to rotate at a low speed, and the motor output shaft drives the first gear 243 to revolve around the second gear 244, thereby driving the two connected arms 241 to eccentrically swing around the conveying auger 22. At this time, under the constraint of the first guide slot 2121, the rotating shaft 23 slides linearly in the horizontal direction, thereby approaching or moving away from the conveying auger 22, adjusting the distance between the two shafts. At the same time, because the motor output end is fixedly connected to the fourth gear 254, the fourth gear 254 moves in an arc with the motor output end within the second guide slot 2122, centered on the axis of the conveying auger 22, achieving coordinated guidance and transmission during the adjustment process.

[0042] After the spacing is adjusted, the output end of the electric push rod 252 is extended again, causing the mounting frame 251 to retract. The first latch 2511 disengages the third gear 253, and the conveyor auger 22 resumes its rotational state. Simultaneously, the second latch 2512 reengages the fourth gear 254. Because the motion trajectory of the second latch 2512 is inconsistent with the second guide groove 2122, and the mounting frame 251 is a rigid, fixed structure, the fourth gear 254 is restrained by the second latch 2512 and locked, preventing it from rotating or sliding along the second guide groove 2122. At this point, the motor output end returns to its axially fixed state and no longer swings, and the support arm 241 remains stable.

[0043] On this basis, the motor 242 is controlled to operate, and its output shaft drives the first gear 243 and the first pulley 245 to rotate normally. The first gear 243 drives the second gear 244 to rotate, realizing power output to the conveying auger 22. The first pulley 245 drives the second pulley 246 to rotate via the transmission belt 247, thereby driving the rotating shaft 23 to move synchronously, realizing the simultaneous drive of the rotating shaft and the conveying auger. At the same time, the conveying auger 22 drives the third gear 253 to rotate. The third gear 253 is now in an unlocked state and no longer affects the overall transmission system.

[0044] The adjustment mechanism drives the mounting frame 251 through the electric push rod 252 to achieve precise adjustment of the spacing between the conveying auger 22 and the rotating shaft 23. Combined with the coordinated guidance of the first guide groove 2121 and the second guide groove 2122, the sorting gap can be flexibly adjusted to meet the screening requirements of agricultural products of different specifications without disassembling the motor 242 or adjusting the overall structure; at the same time, stable positioning is achieved during the adjustment process through the locking mechanism of the first latch tooth 2511 and the third gear 253 and the second latch tooth 2512 and the fourth gear 254, ensuring the synchronization and stability of the conveying auger 22 and the rotating shaft 23 during operation, effectively improving the sorting accuracy and equipment reliability, reducing the intensity of manual adjustment, and enhancing the automation level and ease of use of the system.

[0045] In this embodiment, the frame 1 includes a base 11, two first brackets 12 and a second bracket 13; the two first brackets 12 are symmetrically arranged on the left and right sides of the base 11, and are fixedly connected to the base 11 by welding or screwing, respectively, to form a vertical support structure; the second bracket 13 is arranged between the two first brackets 12, and is also fixedly connected to the base 11 by screwing or slot locking. The three together constitute a stable three-dimensional frame structure for carrying the conveying mechanism 2, the first storage box 3 and related components.

[0046] A first crossbeam 14 is disposed between the two first brackets 12. This crossbeam 14 horizontally connects the two first brackets 12, enhancing overall stability between the brackets and providing a mounting platform. The housing 21 is fixedly mounted on the first crossbeam 14, preferably by screws or slots, to the upper surface of the first crossbeam 14. This ensures stable positioning of the housing 21, ensuring good support stiffness and vibration suppression for the conveying auger 22 and rotating shaft 23 during operation.

[0047] A second crossbeam 15 is disposed between the first bracket 12 and the second bracket 13. This crossbeam 15 is positioned in the middle of the frame 1 and supports the first storage box 3. The main body of the first storage box 3 is connected to the second crossbeam 15 via structural components or mounting sliders, ensuring that agricultural products can reliably enter the first storage box 3 after transport and sorting, while also ensuring that the first storage box 3 has a good load-bearing capacity when installed.

[0048] In this embodiment, a second storage box 16 is provided on the base 11. This second storage box 16 is positioned directly below the lowermost conveyor mechanism 2. Its opening faces upward and is fixed to the surface of the base 11 or embedded within its interior. This second storage box 16 receives the smallest agricultural products sorted by the conveyor mechanism 2, forming the final collection step in the entire sorting process. This arrangement ensures that small agricultural products fall directly into the second storage box 16 under the influence of natural gravity, eliminating the need for additional guide structures and improving the overall simplicity and collection efficiency of the system.

[0049] In this embodiment, contact portions 31 are provided on both sides of the first storage box 3. The contact portions 31 are preferably slide rail structures or guide wheel structures. Specifically, the slide rail structure can be an L-shaped or U-shaped slide groove installed on the side walls of the first storage box 3; the guide wheel structure includes a rotating pulley installed on the side of the storage box and a sliding track that matches the second crossbeam 15. The above structure is slidably connected to the second crossbeam 15, allowing the first storage box 3 to move linearly in the horizontal direction when installed, thereby achieving rapid storage box extraction or replacement. After the agricultural products are screened and collected in the first storage box 3, the operator can directly apply force to pull the main body of the first storage box 3. Under the guidance of the contact portion 31, it can slide out of the second crossbeam 15 along the track, achieving overall separation from the frame 1, facilitating the transfer of full storage boxes to the next process for weighing, packaging, or replacement of empty boxes, thereby improving the efficiency and convenience of subsequent processing.

[0050] In this embodiment, the lower end of the shell 21 is connected to a first guide portion 26 and a second guide portion 27; both guide portions are fixed to the lower edge of the shell 21 and extend toward the conveying mechanism 2 and the first storage box 3 on the next level, respectively, to form a flexible guide channel. Both the first guide portion 26 and the second guide portion 27 are made of knitted fabric, which has excellent softness and cushioning properties. Knitted fabric can mitigate the impact of agricultural products when they fall naturally, preventing damage to the surface. It is particularly suitable for fruits and vegetables with delicate skins, such as tomatoes and apples. Both guide portions have a structural profile that gradually decreases from top to bottom, with their cross-sections tightening layer by layer, forming a trumpet-shaped or tapered guide path, guiding the agricultural products in a predetermined direction and preventing them from shifting or rolling out during discharge.

[0051] Among them, the first guide part 26 is arranged directly below the shell 21 and is correspondingly connected to the lower conveying mechanism 2, and is used to smoothly guide the small-sized agricultural products that have passed the screening to the next-level conveying mechanism 2 to complete the further sorting process; and the second guide part 27 is offset, and its lower end is corresponding to the first storage box 3, and is used to guide large-sized agricultural products that have not passed the sorting gap directly into the first storage box 3, ensuring that the residual agricultural products after screening are effectively collected and prevented from being damaged by free fall.

[0052] In this embodiment, a guide plate 32 is provided at the upper end of the first storage box 3. This plate is a slanted, sheet-like structure, its inclination aligned with the discharge direction of the lower end of the second guide portion 27. The two guides are positioned in a corresponding manner, forming a smooth connection channel. The guide plate 32 expands the area of ​​the guide opening and acts as a buffer and disperser, slowing down and adjusting the orientation of incoming agricultural products before they enter the first storage box 3, preventing them from directly impacting the box bottom or accumulating and shifting.

[0053] The first storage box 3 is internally provided with a protrusion 33, which can be strip-shaped or tapered and located near or along the centerline of the storage box. This protrusion 33 serves to naturally divert fallen agricultural products to the left and right sides of the first storage box 3. This guiding structure effectively prevents agricultural products from concentrating on one side of the storage box, causing tilting, stacking, or wasted space. This further optimizes the storage volume and improves loading uniformity.

[0054] In this embodiment, the interior of the first storage box 3 is further provided with multiple elastic bands 34. These bands 34 are arranged horizontally within the storage box and staggered vertically, forming a structure similar to an elastic buffer net. When agricultural products are introduced into the storage box via the guide portion, they first come into contact with the upper elastic band 34. These elastic bands gradually absorb the potential energy of the fall through their elastic deformation properties, providing a buffering and shock-absorbing function and preventing physical damage or surface cracks caused by excessive gravitational acceleration. The elastic bands 34 can be made of rubber, PU elastic bands, or woven nylon, offering both good elasticity and sufficient support strength to ensure continued use after multiple drops, extending the equipment's service life and maintaining sorting accuracy.

[0055] In this embodiment, the agricultural product sorting workstation with transport functionality also includes a control panel 4 mounted on the frame 1. This control panel 4 is prominently located on the frame 1, facilitating centralized control and monitoring by the operator. A controller is internally housed within the control panel 4, which is electrically connected to the drive assembly 24 and the adjustment assembly 25, forming an integrated control system.

[0056] The controller can adjust the start, stop, and speed of the motor 242 in the drive assembly 24 in real time according to preset programs or operating instructions, achieving synchronous drive of the conveying auger 22 and the rotating shaft 23, thereby ensuring continuous conveyance and efficient sorting of agricultural products. Simultaneously, the controller can also control the telescopic movement of the electric push rod 252 in the adjustment assembly 25, automatically adjusting the distance between the conveying auger 22 and the rotating shaft 23 to meet the needs of screening agricultural products of different specifications.

[0057] Through the integrated controls of the control panel 4, operators can intuitively set sorting parameters and adjust procedures. The controller automatically optimizes drive and adjustment actions based on real-time feedback signals, improving the equipment's automation level and response speed, and reducing human error. The control panel also facilitates safety monitoring and fault diagnosis of the entire workstation, ensuring stable equipment operation.

[0058] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
