Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a device and method for screening, feeding, cutting, and seed production of tuberous roots. Background Technology

[0002] In the cultivation of root crops such as potatoes, seed potatoes, and taro, screening, feeding, and cutting are crucial steps. These traditional steps largely rely on heavy manual labor, leading to low efficiency. Therefore, developing efficient and precise equipment for screening, feeding, and cutting root crops is essential, not only to meet the needs of large-scale cultivation but also to ensure consistency in quality and specifications, thereby improving planting success rates and yields.

[0003] An existing technology discloses an intelligent seed production device and method based on multi-level screening and bud eye recognition. Application No.: 202010556037.8 integrates screening and feeding, bud eye recognition, cutting, and mixing functions, overcoming the problems of blade disinfection and multi-level potato sorting. However, potatoes are prone to disorder during transportation, making correct screening impossible and causing frequent jams, resulting in low work efficiency. The intelligent seed production device and method based on multi-level screening and bud eye recognition, patent No. 202010556037.8, also suffers from the problems of disorder and jams during potato transportation, making correct screening impossible. Furthermore, during subsequent switching, the receiving tray rotates along the vertical axis, causing each pair of circular grooves on the receiving tray to switch between the feeding station, recognition station, cutting station, and disinfection station. This working method makes it impossible to synchronize tools between different processes, resulting in low work efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a seed production device for screening, feeding, and cutting root vegetables. This device utilizes the interaction between the gravity of the seed potatoes and V-shaped rollers, with the V-shaped rollers maintaining their rotation using the weight of the seed potatoes themselves, ensuring orderly and smooth seed potato transport. The design of synchronous movement of dual conveyor belts further improves work efficiency.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] In a first aspect, a root vegetable screening, feeding, and cutting device for seed production includes:

[0007] The sequencing and separation mechanism is equipped with a multi-stage sorting track for screening seed potatoes. V-shaped rollers are evenly distributed on the sorting track to maintain rolling by the weight of the seed potatoes themselves, ensuring orderly transport of the seed potatoes.

[0008] The dual-track identification and cutting mechanism is used to receive the screened seed potatoes. It includes two sets of parallel conveyor belts. The two sets of conveyor belts are linked to drive the seed potatoes to move and complete the eye identification and cutting steps in sequence.

[0009] The storage hopper, located at the end of the dual-track identification and cutting mechanism, is used to store the seed potatoes after they have been cut into pieces.

[0010] As a further implementation, the sequencing and sorting mechanism includes a turntable that can rotate along its own central axis, with the exit end of the turntable connected to a multi-stage sorting track.

[0011] As a further implementation, the multi-level sorting track includes a primary sorting track and a secondary sorting track, with the primary sorting track located above the secondary sorting track, and anti-collision nets provided on both sides of the multi-level sorting track.

[0012] As a further implementation, a primary sorting port is provided at one end of the primary sorting track near the turntable exit.

[0013] As a further implementation, the primary sorting track is provided with a secondary sorting port, which is located directly above the front end of the secondary sorting track. The front end of the primary sorting track is located between the secondary sorting track and the turntable outlet. The size of the secondary sorting port is larger than that of the primary sorting port. The end of the secondary sorting port is provided with a discharge port. A rotatable limiting piece is provided on the outer side of the anti-collision net near the discharge port. The limiting piece is used to push the seed potatoes on the secondary sorting track to the discharge port.

[0014] As a further implementation, the V-shaped rollers are arranged sequentially along the sorting track, and the two ends of the V-shaped rollers are mounted on the corresponding track by pins and bearings.

[0015] As a further implementation, a pre-cutting mechanism is provided between the dual-track identification and cutting mechanism and the sequencing and screening separation mechanism. The dual-track identification and cutting mechanism includes a mounting and positioning frame. The conveyor belt is located inside the mounting and positioning frame. The mounting and positioning frame at the top of the conveyor belt is sequentially provided with a bud eye identification mechanism, a CNC tool magazine, and a spraying mechanism, which are corresponding to the two sets of conveyor belts.

[0016] As a further implementation, a stepper motor is also included, which is located between two sets of conveyor belts. The two ends of the two sets of conveyor belts are connected by a drive shaft. The two ends of the drive shaft are engaged with the same end of the conveyor belt through ratchet pawls. One set of drive shafts is engaged with the sprocket at the output end of the stepper motor through a sprocket and a chain.

[0017] As a further implementation, ratchet pawl grooves are evenly distributed on the inner surfaces of the conveyor belt and the ratchet pawl, and bearing discs are evenly distributed on the outer surface of the conveyor belt.

[0018] Secondly, a method for screening, feeding, and cutting root crops into seed pieces, employing any of the above-described root crop screening, feeding, and cutting seed pieces device, includes the following steps:

[0019] Seed potatoes are dispersed as they enter the turntable. The turntable rotates, causing the short diameter of the seed potatoes to be perpendicular to the direction of movement. They are then sent to a multi-stage sorting track for screening. Seed potatoes entering the secondary sorting track pass through the discharge port and the pre-cutting mechanism in sequence, falling onto the carrier plate of the conveyor belt of the dual-track identification and cutting mechanism. The two sets of conveyor belts move synchronously, driving the pre-cut seed potatoes through bud identification, cutting, spray sterilization, and then into the storage hopper.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. This invention utilizes the interaction between the gravity of the seed potato and the V-shaped roller. The V-shaped roller maintains rolling by utilizing the weight of the seed potato itself, ensuring orderly and smooth transport of the seed potato. The shape design of the V-shaped roller ensures that the seed potato always slides stably in the middle position of the V-shaped roller, reducing the possibility of collision between the seed potato and the anti-collision net, and ensuring that the seed potato can be sorted in an orderly manner.

[0022] 2. The design of the dual conveyor belts moving synchronously in this invention improves work efficiency while simplifying the identification and cutting structure. After spraying and disinfection, the seed potatoes can be directly put into the storage hopper for use. The two conveyor belts transport the seed potatoes synchronously, but identify the cutting method asynchronously. The purpose is to avoid the two sets of identification signals interfering with the cutting position, which could lead to low seed potato quality and low nutritional content.

Detailed Implementation

[0035] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0036] Example 1

[0037] In a typical embodiment of the present invention, reference is made to Figures 1-7 As shown, a tuberous root screening, feeding, and cutting seed production device includes a sequentially arranged sequential screening and separation mechanism I, a dual-track identification and cutting mechanism II, and a storage hopper III.

[0038] like Figure 1As shown, the sequencing and screening separation mechanism I is located at the top of the dual-track identification and cutting mechanism II. The sequencing and screening separation mechanism I is used to screen seed potatoes of appropriate size. The dual-track identification and cutting mechanism II is used to identify the buds of the seed potatoes, cut them into pieces, and perform spray sterilization. The storage hopper III is located at the end of the dual-track identification and cutting mechanism II and is used to collect and store the seed potato pieces after spraying. A pre-cutting mechanism is also provided between the sequencing and screening separation mechanism I and the dual-track identification and cutting mechanism II. This pre-cutting mechanism receives the seed potatoes discharged from the sequencing and screening separation mechanism I and cuts them in half along the plane of symmetry of their long axis. The pre-cutting mechanism is existing technology and will not be described in detail here.

[0039] like Figure 1 and Figure 2 As shown, the sequencing and separation mechanism includes a multi-stage sorting track for screening seed potatoes and a turntable that can rotate along its own central axis. The outlet end of the turntable is connected to the multi-stage sorting track. Seed potatoes can be dispersed when they enter the turntable. As the turntable rotates, the short diameter of the seed potatoes is sent out perpendicular to the direction of movement. The turntable adopts existing technology.

[0040] The sequencing and separation mechanism I includes a primary sorting track I-01, a secondary sorting track I-02, a primary sorting port I-03, a secondary sorting port I-04, a V-shaped roller I-05, a limiting plate I-06, a stepper motor I-07, bolts I-08, a load-bearing plate I-09, a crash barrier I-10, and a discharge port I-11.

[0041] As shown in Figures 3(a) and 3(b), the multi-stage sorting track includes a primary sorting track I-01 and a secondary sorting track I-02. The primary sorting track I-01 is located above the secondary sorting track, and anti-collision nets I-10 are provided on both sides of the multi-stage sorting track by bolts I-08.

[0042] V-shaped rollers I-05 are evenly distributed on the sorting track. These rollers are rotatable, and when seed potatoes are on them, they are kept rolling by their own weight, ensuring orderly transport. The V-shaped rollers I-05 include roller I-0504, whose cross-section is V-shaped. Figure 4 As shown, roller I-0504 has pins I-0503 at both ends. Pins I-0503 are rotatably mounted on the multi-stage sorting track via bearings I-0502 and washers I-0501.

[0043] As shown in Figures 3(a) and 3(b), a primary sorting track I-01 has a primary sorting port I-03 at one end near the turntable exit, and a secondary sorting port I-04 is located on the primary sorting track I-01, directly above the front end of the secondary sorting track. The front end of the primary sorting track I-01 is located between the secondary sorting track I-02 and the turntable exit.

[0044] The secondary sorting port I-04 is larger than the primary sorting port I-03, and a discharge port I-11 is located at the end of the secondary sorting port I-04. It can be understood that the sorting ports are set on the track, meaning that the opening is achieved without the V-shaped roller I-05 at this location. The primary sorting port I-03 is designed to filter out small-sized seed potatoes and impurities such as stones and mud clumps. The remaining seed potatoes continue to slide down due to their own gravity.

[0045] In this embodiment, the gravity of the seed potato interacts with the rotatable V-shaped roller, allowing the V-shaped roller to maintain its rotation using the seed potato's own weight, ensuring orderly and smooth transport of the seed potato. The V-shaped roller's design ensures that the seed potato always slides stably in the middle position of the roller, reducing the possibility of collisions between the seed potato and the anti-collision net, and further protecting the seed potato.

[0046] After reaching the secondary sorting port, seed potatoes weighing 50-160g are transferred to the secondary sorting track I-02. Seed potatoes larger than this size cannot enter the secondary sorting port and are discharged at the end of the primary sorting track I-01, without participating in subsequent work.

[0047] A load-bearing plate I-09 is provided on the outer side of the anti-collision net I-10 near the material discharge port. A stepper motor is provided on the load-bearing plate I-09. A limit plate I-06 is provided at the output end of the stepper motor. The anti-collision net I-10 has an opening corresponding to the limit plate I-06. The limit plate I-06 can rotate to be above the secondary sorting track I-02, pushing the seed potatoes on the secondary sorting track I-02 to the material discharge port I-11. The working method of the limit plate adopts existing technology.

[0048] 50-160g seed potatoes are transferred to the end of the secondary sorting track I-02. After being moved by the limiting plate, they enter the pre-cutting mechanism from the discharge port and then fall onto the conveyor belt of the dual-track identification and cutting mechanism.

[0049] The dual-track identification and cutting mechanism is used to receive the screened seed potatoes. It includes two sets of parallel conveyor belts. The two sets of conveyor belts are linked to drive the seed potatoes to move and complete the steps of bud identification, cutting and spraying in sequence.

[0050] The dual-track identification and cutting mechanism includes a mounting and positioning frame II-01, angle iron II-02, bud eye identification mechanism II-03, CNC tool magazine II-04, spraying mechanism II-05, stepper motor II-06, conveyor belt II-07, sprocket II-08, chain II-09, drive shaft II-10, bearing seat II-11, ratchet pawl II-12, ratchet pawl groove II-071, and bearing plate II-072.

[0051] like Figures 5-7As shown, the dual-track identification and cutting mechanism includes a mounting and positioning frame II-01, which is arranged in an inverted U-shape. Angle iron II-02 is provided at the corner to improve strength. Two sets of conveyor belts II-07 are located inside the mounting and positioning frame. On the lower surface of the top plate of the mounting and positioning frame II-01 at the top of the conveyor belts II-07, there are sequentially arranged a bud eye identification mechanism II-03, a CNC knife magazine II-04, and a spraying mechanism II-05, which are corresponding to the two sets of conveyor belts II-07. The bud eye identification mechanism II-03, the CNC knife magazine II-04, and the spraying mechanism II-05 are existing technologies, and each has two sets. Each set is distributed in a straight line and is correspondingly set above each set of conveyor belts. The CNC knife magazine II-04 is used to cut the seed potatoes into small pieces of 25g-30g.

[0052] Two sets of conveyor belts II-07 are supported by a support frame, with a stepper motor II-06 mounted between them. The two sets of conveyor belts II-07 are arranged in parallel and connected at both ends by a drive shaft II-10. The drive shaft II-10 is rotatable, and its two ends engage with the same end of both conveyor belts II-07 via ratchet pawls II-12. The outermost end of the drive shaft is connected to a bearing housing II-11. One set of drive shafts II-10 engages with a sprocket II-08 at the output end of the stepper motor via a sprocket and chain. When the stepper motor II-06 rotates, it drives one set of drive shafts II-10 to rotate via the sprocket II-08 and chain II-09, thus enabling the two conveyor belts to move.

[0053] like Figure 7 As shown, ratchet pawl grooves II-071 are evenly distributed on the inner sides of conveyor belt II-07 and ratchet pawl II-12. The ratchet pawl grooves II-071 are used to cooperate with the ratchet pawl II-12. The rotation of the drive shaft drives the ratchet pawl II-12 to rotate. The rotation of the ratchet pawl II-12 and its continuous cooperation with the ratchet pawl grooves II-071 enable the two sets of conveyor belts to be driven to transport synchronously, thereby improving work efficiency.

[0054] The outer surface of the conveyor belt II-07 is evenly distributed with bearing plates II-072. The bearing plates II-072 are used to receive the seed potatoes after pre-cutting. The two sets of conveyor belts simultaneously drive the seed potatoes through the bearing plates and complete the steps of bud identification, cutting, and spraying in sequence. After that, the seed potatoes are cut into pieces and enter the storage hopper, and the whole work is completed.

[0055] Two conveyor belts (II-07) operate separately, doubling production efficiency. After being fed into the system, the seed potatoes pass through a bud identification station. An intelligent recognition algorithm identifies the bud location, processes the data, and sends instructions. Next, the seed potatoes pass through a cutting magazine, which receives instructions and rotates the potatoes to ensure bud integrity and bud breakage. Finally, the seed potatoes pass through a spray system, which periodically sprays them to sterilize them, simplifying the mixing process and improving overall production efficiency.

[0056] This embodiment features a dual conveyor belt II-07 synchronous movement design, which improves work efficiency while simplifying the identification and cutting structure. After spraying and disinfection, the seed potatoes are directly fed into the storage hopper for use. This embodiment uses two conveyor belts to transport seed potatoes synchronously, but with asynchronous identification and cutting methods. This is to avoid interference between the two sets of identification signals at the cutting position, which could lead to low seed potato quality and nutritional content.

[0057] In this embodiment, the storage hopper is designed with a certain angle. The chopped seeds fall directly into the storage hopper, which is pre-lined with wood ash. This allows the seeds to fall safely while protecting the wet seeds at the bottom, preventing them from rotting after planting.

[0058] It should be noted that due to the wide variety of seed potatoes, their skin smoothness and shape vary. The parameters mentioned in the calculations above are only applicable to specific varieties. The device parameters need to be adjusted for different seed potato varieties. The addition of V-shaped rollers in the sorting track enables orderly transport of seed potatoes and precise screening of those within a suitable quality range. However, for seed potatoes required for other root crops such as taro, the slope toe and surface lubrication must be comprehensively considered to accommodate high-quality, high-precision comprehensive screening of different seed potato types. Given the large number of seed potato varieties, specific customized parameters are not listed here; only the determination method is provided.

[0059] Example 2

[0060] In a typical embodiment of the present invention, reference is made to Figures 1-7 As shown, a method for screening, feeding, and cutting root crops into seed pieces, using a root crop screening, feeding, and cutting seed piece device from Embodiment 1, includes the following steps:

[0061] Seed potatoes are dispersed upon entering the turntable. As the turntable rotates, the short diameter of the seed potatoes is perpendicular to the direction of movement and fed into a multi-stage sorting track for screening. First, small-sized seed potatoes and impurities such as stones and mud are removed through the primary sorting port. Then, the seed potatoes are transported along the primary sorting track. The interaction between the weight of the seed potatoes and the rotatable V-shaped rollers ensures that the V-shaped rollers maintain their rotation using the seed potatoes' own weight, guaranteeing orderly and smooth transport. The V-shaped rollers' design ensures that the seed potatoes always slide stably in the center of the roller, reducing the possibility of collisions with the anti-collision net and further protecting the seed potatoes.

[0062] After reaching the secondary sorting port, seed potatoes weighing 50-160g are transferred to the secondary sorting track. Seed potatoes larger than this size cannot enter the secondary sorting port and are discharged at the end of the primary sorting track, and do not participate in subsequent work.

[0063] 50-160g seed potatoes are transferred from the secondary sorting port to the end of the secondary sorting track. After being propelled by the limiting plate, they enter the pre-cutting mechanism from the discharge port, and then fall onto the carrier plate of the conveyor belt of the dual-track identification and cutting mechanism. The two conveyor belts move synchronously, driving the pre-cut seed potatoes through bud identification, cutting, and spray sterilization in sequence before entering the storage hopper. The design of synchronous movement of the dual conveyor belts in this embodiment improves work efficiency while simplifying the identification and cutting structure. After spray sterilization, the seeds directly enter the storage hopper for use. This embodiment uses two conveyor belts to transport seed potatoes synchronously, but with asynchronous identification and cutting. The purpose is to avoid the two sets of identification signals interfering with the cutting position, which could lead to low seed potato quality and nutritional content.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
