Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a terminal bud-cutting type seed potato cutting system. Background Art

[0002] Potato is an important food crop in the world after rice and wheat. It is a stem and root crop that reproduces asexually by tubers. Manual cutting is generally used to cut seed potatoes during the planting process. This method has low work efficiency and high labor costs. Currently, there are few potato seed potato cutting equipment on the market and the process flow is not perfect. There are three core problems: 1. It is difficult to cut potatoes uniformly due to their own morphological differences; 2. The uniformity of cutting is difficult to control; 3. The advantage of potato's apical buds is not fully utilized.

[0003] Due to the large individual differences of potatoes, although there is a statistical Gaussian probability distribution in morphology, that is, most of them are slightly flattened ellipsoids, it is difficult for mechanical devices to flexibly fix potatoes of different shapes for cutting as manually; at the same time, according to the current agronomic requirements for potato cutting, each potato tuber cut out must have at least one bud eye, and the proportion of potato tubers without bud eyes must not exceed 3%, which puts forward higher requirements for mechanical cutting. In order to meet the above requirements, the general method adopted by existing cutting equipment is to sacrifice a reasonable number of cuts to ensure the number of cut bud eyes. This practice not only wastes seed resources but also greatly reduces the required sowing area; in addition, existing studies have shown that potato tubers with partial terminal buds (i.e., terminal buds are divided into 2 or 3 bud blocks) have greater advantages in sprouting speed, later growth and final yield than other side bud potato tubers, but the existing seed potato cutting equipment generally adopts non-directional cutting, and the proportion of potato tubers with terminal buds after cutting is less than one-third, and the probability of the terminal bud being cut into a potato tuber as a bud body is as high as more than 90%, resulting in a great waste of the advantages brought by terminal bud cutting.

[0004] Chinese patent application number 2013102160068 discloses an automatic potato seed potato dicing machine, which solves the problem of uneven manual dicing; Chinese patent application number 2024203013799 discloses a potato seed potato cutter, which does not require manual unloading and reduces the workload of the staff; but it is obvious that these technical solutions are difficult to meet the above-mentioned agronomic needs, and therefore a technical solution for potato seed potato dicing is needed to solve the above-mentioned problems. Summary of the invention

A cutter driving member is also provided on the main body bracket. The cutter driving member is transmission-connected to the block cutting device and drives the block cutting device to reciprocate up and down. A cutter body is provided on the block cutting device, and the cutter body is arranged corresponding to the through-port and the gap between the two threaded rollers.

[0007] Furthermore, a distribution device is provided between the seed potato grading system and the seed potato cutting system, and the graded seed potatoes are distributed to a plurality of seed potato cutting systems through the distribution device.

[0009] Furthermore, the axis adjustment device drives the seed potato to move toward the output end through the rotation of the threaded roller. During the movement of the seed potato, the seed potato is adaptively flipped due to the difference in friction between the seed potato and the two threaded rollers, so that the friction on both sides of the seed potato is balanced, and the center axis of the seed potato is brought close to the center lines of the two threaded rollers, and the center axis of the seed potato is vertically aligned with the middle line of the two threaded rollers.

[0012] Furthermore, the knife body includes an L-shaped knife body, a T-shaped knife body, an X-shaped knife body and a S-shaped knife body, which are used to cut second-level, third-level, fourth-level and fifth-level seed potatoes respectively.

[0014] In some embodiments, the monitoring and control system includes a laser transmitting and receiving pair of tubes arranged near the main support, and determines the movement speed and longitudinal length of the seed potato by the pulse width formed by blocking the laser beam at the front and rear ends of each seed potato, thereby controlling the cutting device to cut at the corresponding position of the seed potato.

[0017] The beneficial effects of the present invention are: 1. The symmetrical double-threaded roller conveying mechanism can adjust the long axis center line of the potato to the plane where the longitudinal cutter is located during the conveying process, effectively solving the problem of mechanized cutting caused by the difference in potato shape. 2. By adopting the grading and cutting of seed potatoes and cutting with a variety of cutters, the apical bud cutting rate has been increased from less than 3% to 100% compared with the traditional non-directional cutting method, and the proportion of potato tubers with apical buds has been greatly increased from 33% in non-directional cutting to 61%. Because the advantages of apical buds are fully utilized, the emergence of potato seedlings in the field, the consistency of growth, and the final yield will be significantly improved.

[0018] 3. The production volume of cutting blocks in each time period can be accurately calculated during the cutting operation.

[0019] 4. Through the combination of intelligent electronic control system and artificial intelligence counting, the visual image can be intelligently recognized to determine the shape of the seed potato and accurately identify the position of the top bud, thereby achieving accurate and uniform cutting; at the same time, it can also effectively determine the degree of wear of the tool, which can provide strong guarantee for the efficient operation of the equipment.

[0020] 5. The linear reciprocating motion of the cutter device will not cause unnecessary travel, thus maximizing the work efficiency. At the same time, the simple structure of the rack and the fixed sleeve will further reduce the tool change time, which is conducive to large-scale production and is a significant improvement over the existing technology.

[0024] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] According to the agronomic requirements of existing potato seed potato cutting, potatoes are divided into the following five grades according to weight and different cutting methods are adopted, please refer to Figure 8 : First-grade, 25-50g seed potatoes are sown directly; Secondary, 51-100g seed potatoes are cut along the top bud (i.e. along the long axis of the potato, also called longitudinal cut) into two pieces; For the third-grade, 101-150g seed potatoes, cut one-third of the length of the long axis from the root (i.e., perpendicular to the long axis of the potato), and then cut the remaining part in half along the top bud to form three petals; For the fourth-grade seed potatoes weighing 151-200g, cut them into two pieces along the top bud and then cut them in half horizontally to form four pieces. After cutting a quarter of the long axis length from the root of the fifth-grade, 201-250g seed potatoes, the remaining long axis length is evenly divided into horizontal and vertical cuts, into a total of 5 petals.

[0029] According to the above agronomic regulations, each type of cutting involves cutting along the terminal bud. In order to achieve the above requirements, the present invention provides the following technical solutions: Example 1

[0030] See also Figure 1-10The terminal bud cutting type potato seed potato cutting system shown in a preferred embodiment of the present application includes a raw seed potato conveying system, a seed potato grading system and a seed potato cutting system. The raw seed potato conveying system conveys the potatoes to be processed to the seed potato grading system and then divides the potatoes into five grades according to their weight. Then the seed potato cutting system performs different cutting processes on the potatoes according to their grades or directly conveys them to a finished potato tuber bin.

[0031] Since potatoes of different grades account for different proportions, a distributor is provided between the seed potato grading system and the seed potato cutting system. Potatoes of a larger grade are distributed to multiple seed potato cutting systems through the distributor to prevent partial overload and partial shortage.

[0032] After the potatoes of each grade are cut into pieces, they are transported uniformly through the cutting collection belt conveyor, and then sent to the seed dressing buffer box and seed mixing machine for liquid coating treatment, and then transported to the finished potato tuber warehouse to wait for sowing.

[0033] The seed potato grading system includes a belt conveyor line 62 and a belt motor 61 connected thereto. A pair of inlet guide plates 63 are provided at the input end of the belt conveyor line 62 to guide and guide the seed potatoes transported by the raw material seed potato transport system and send them into the visual collection device 64. Five linearly arranged material dividing motors 66 are arranged above the belt conveyor line 62, and push plates 67 are arranged on the rotating shafts of the material dividing motors 66. Material dividing baffles 65 are arranged on both sides of the belt conveyor line 62, and four material dividing partitions 68 are arranged on the material dividing baffles 65. The material dividing baffles 65 are divided into five graded output ports corresponding to the above-mentioned material dividing motors 66 through the material dividing partitions 68. Each graded output port is provided with a flexible channel and is connected to the input end of the corresponding seed potato cutting system through the flexible channel.

[0034] During operation, the visual acquisition device 64 identifies each passing seed potato and grades the seed potatoes, and then controls the corresponding material dividing motor 66 to push the seed potatoes from the belt conveyor line 62 into the corresponding grading output port.

[0035] As the focus of this application, the seed potato cutting system includes a main frame 1, an axis adjustment device 2, a cutting device 3 and a roller servo motor 5 arranged on the main frame 1; the axis adjustment device 2 includes a pair of threaded rollers arranged in parallel and symmetrically, and the threaded rollers are rotatably arranged on the main frame 1; Specifically, a through opening 22 is provided on the threaded roller, and the threaded roller is divided into a center axis adjustment section 21 and a discharge section 23 through the through opening 22 . A transmission gear 51 is provided on one side of the center axis adjustment section 21 of the threaded roller.

[0036] Specifically, a cutting guide groove 4 is provided on one side of the threaded roller located at the discharge section 23, so as to guide the cut seed potato pieces to the cutting collection belt conveyor.

[0037] Preferably, the diameter of the threaded roller is 90-110 mm, the length of the center axis adjustment section 21 is 950-1000 mm, the length of the discharge section 23 is 200-250 mm, the width of the through opening 22 is 10-15 mm, and the gap between the two threaded rollers is 10-15 mm.

[0038] A pair of transmission shafts are rotatably arranged on the main frame 1, and a pair of guide gears 52 and a driving gear 53 are fixedly arranged on the transmission shafts. The two guide gears 52 mesh with each other to make the transmission shaft rotate in opposite directions. The two guide wheels are respectively connected to the two transmission gears 51 through chains or belts (not shown); Furthermore, the output shaft of the roller servo motor 5 is connected to one of the transmission shafts through a coupling, and drives the threaded roller to turn from the inside to the inside at a constant speed. For details, please refer to Figure 3 ; During the flipping process, the potatoes between the threaded rollers move forward under the combined force of the friction forces on both sides formed by their own weight. Affected by the shape of the potatoes, the side on which the potato covers more on the threaded roller will have a greater gravity acting on that side (i.e. the center axis of the potato is offset to the side of that roller), thus forming a greater friction force. The combined force formed by this friction force and the friction force of the other roller will generate a torque that causes the potato to flip. This flipping torque causes the potato to flip toward the other roller, so that the center axis of the potato approaches the center line of the two rollers, and as the two rollers continue to rotate, the friction force formed by the gravity on both sides gradually reaches a balance, and finally the center axis of the potato coincides with the center line of the two rollers in the vertical direction.

[0039] After the above adjustment, when the seed potatoes are cut, the central axis of the seed potatoes coincides with the falling plane of the cutter 31. Because the potato apical bud is located at the top of the central axis, the longitudinal cutter 31 can perfectly cut the apical bud from the middle when it arrives, thereby achieving uniform longitudinal cutting of the seed potatoes while achieving the cutting of the apical bud.

[0040] The block cutting device 3 includes a block cutting drive device and a cutter 31, and is arranged above the axis adjustment device 2. The block cutting drive device includes a rack 36 and a fixed slider 34 fixedly arranged on the main support 1. The back of the rack 36 is provided with a guide rail 35 corresponding to the fixed slider 34, so that the rack 36 is slidably connected to the main support 1. The bottom of the rack 36 is connected to a fixed sleeve 33, and the bottom of the fixed sleeve 33 is fixedly connected to the knife rod 32. The bottom of the knife rod 32 is provided with a cutter 31, and the cutter 31 is arranged corresponding to the gap between the through port 22 and the threaded roller.

[0041] Furthermore, a driving motor (not shown) is also provided on the main support 1, and a gear corresponding to the rack 36 is provided on the rotating shaft of the driving motor, so that the cutting device 3 is driven to reciprocate up and down through the rotation of the gear.

[0042] Preferably, the fixing sleeve 33, the knife rod 32 and the cutting knife 31 are of an integrated design to facilitate subsequent knife changing operations.

[0043] As mentioned above, the present invention has five potato processing methods, four of which require cutting by the cutter 31. Therefore, the cutter 31 in the present invention includes an L-shaped cutter 31, a T-shaped cutter 31, an X-shaped cutter 31 and a t-shaped cutter 31, which correspond to the four cutting methods of secondary, tertiary, quaternary and quintuple potatoes, respectively. Figure 6 .

[0044] Specifically, it can be seen from the figure that the L-type cutter 31 includes a longitudinal blade, which cuts potatoes and passes through the gap between the threaded rollers during the cutting operation; the T-type cutter 31 and the X-type cutter 31 each include a longitudinal blade and a transverse blade, which pass through the gap between the threaded rollers and the through port 22 respectively during the cutting operation; the T-type cutter 31 includes a longitudinal blade and two transverse blades. On the basis of the X-type cutter 31, an additional transverse blade passes through the gap between the discharge section 23 and the main support 1. The above four types of cutters 31 will not interfere with each other.

[0045] Specifically, the seed potato cutting system also includes an intelligent electric control system electrically connected to each driving component for intelligent control of the equipment; More specifically, the intelligent electronic control system includes a monitoring control system, a tool wear analysis system, and a maximum cutting quantity control system; In some embodiments, the monitoring and control system includes a pair of laser emitting and receiving tubes arranged on the main support 1, and the laser beam of the laser emitting and receiving tubes is perpendicular to the axis of the threaded roller and is located at one end of the central axis adjustment section 21 near the through hole 22. During the movement of the seed potatoes, the pulse width formed by the front and rear ends of each seed potato blocking the laser beam can accurately measure the movement speed and longitudinal length of the seed potatoes. After receiving the signal, the monitoring and control system sends a control instruction to the cutting device 3, forming a calculation basis for the cutting device 3 to implement cutting and return control.

[0046] Preferably, in other embodiments, the monitoring and control system also includes an image acquisition device arranged just above the threaded roller, which obtains the morphological data and motion data of the seed potatoes passing below in real time, extracts the long and short diameter data and morphology thereof through the YOLOV8 algorithm, intelligently determines the position of the apical bud, and transmits this information to the cutting device 3 at the same time, so as to control the moment when the cutting knife 31 falls, thereby ensuring that the apical bud can be cut and the cutting is uniform.

[0047] Specifically, the monitoring and control system simultaneously counts the seed potatoes in real time, and accurately calculates and counts the number of finished pieces according to the seed potato grade, which is conducive to large-scale production, prevents insufficient or excessive seed supply in the field, and realizes the supply of accurate number of seed pieces.

[0048] The tool wear analysis system includes a high-speed camera installed on one side of the block cutting device 3, which is used to capture the image data of the cutter 31 and intelligently compare it with the image data before use to generate tool wear data. After evaluating this data, the decision basis for whether to replace the tool is given. Once the replacement conditions are met, the system will give targeted sound and light prompts (giving tool number, wear level, etc.) through the sound and light alarm to urge maintenance personnel to replace the damaged tool in time.

[0049] The maximum cutting quantity control system includes an embedded AI analysis software and is electrically connected to the raw material seed potato conveying system. By matching the time interval between the input of individual seed potatoes with the roller speed, the seed potato feeding speed and the roller speed are adjusted to the optimal value in an intelligent closed loop to adapt to the fastest reciprocating time of the cutter 31, thereby maximizing production efficiency.

[0050] Final result: After testing the present invention, the applicant obtained the following results: 1. Cutting efficiency: The cutter 31 of the present invention only needs to reciprocate up and down without any extra travel in other directions. The cutter 31 can reciprocate in a cycle of 0.5 seconds, which is very efficient. In comparison, the manual comprehensive cutting speed is about 5 seconds per piece. The present invention is more than 10 times more efficient than manual cutting. 2. Qualified rate of bud eyes: Under the intelligent control of the intelligent electronic control system and the reasonable structure of the equipment, the proportion of each cut block containing at least one bud eye is ≥ 98%, which is better than the standard of the existing agronomic requirement that the ratio of cut blocks without bud eyes should be less than 3% in the manual cutting method; 3. Terminal bud cutting rate: The mechanical structure of the present invention can ensure that more than 83% of the terminal buds are cut, while the terminal bud cutting rate of traditional manual cutting is less than 33.3%.

[0051] 4. Tool changing time: The tool of the present invention is an integrated design. When changing the tool, it is only necessary to withdraw the tool assembly from the fixed sleeve 33 using a wrench or other tools to complete the disassembly. The total tool changing time including disassembly and replacement of a new tool is less than 30 seconds, thereby further ensuring production efficiency. Example 2

[0052] Based on the image acquisition device in Example 1, see Figure 7 When cutting grade three and grade five seed potatoes, the transverse blades of the T-shaped cutter and the S-shaped cutter will cut and separate one end of the seed potato, so there is a 50% probability that the apical bud cannot be cut, thereby reducing the overall apical bud cutting rate.

[0053] To address this problem, in this embodiment, two cutting devices 3 are provided on the main frame, and two groups of through openings 22 are opened on the threaded roller. The two cutting devices 3 are symmetrically arranged and correspond to the two groups of through openings 22 respectively, and are respectively used to longitudinally cut one end of the seed potatoes.

[0054] During operation, after the image acquisition device determines the front and rear positions of the terminal buds on the seed potatoes, the information is transmitted to the corresponding cutting device 3. After the seed potatoes are transported to the corresponding positions, the corresponding cutting device 3 is started and its longitudinal cutter accurately cuts the terminal buds. The double-station cutting structure further improves the process of terminal bud cutting, further improves the terminal bud cutting rate and reaches 100%, and maximizes the advantages of terminal bud cutting, which is an effect that cannot be achieved by the prior art.

[0055] In summary, the present invention effectively solves the three core problems existing in the existing potato seed potato dicing technology and has obvious advantages over the existing technology.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
