Description

Technical Field

[0001] The present invention relates to the technical field of potato seed selection, and in particular to a potato seed selection device and method. Background Art

[0002] In the processing of potato seeds, impurity removal and sorting are key pretreatment processes, which directly affect the storage quality of seeds and subsequent planting effects. Traditional seed processing equipment usually separates impurity removal and sorting, that is, first removes impurities such as soil and stones on the surface of potato seeds through an impurity removal device, and then sizes or grades the potato seeds through a sorting device. This separate processing method has a long process and low efficiency. For example, after the impurity removal of potato seeds, they need to be transferred to the sorting device manually or by a conveying device, and the feeding of impurity removal and the feeding of sorting both require back-and-forth operations, resulting in a reduction in processing efficiency and affecting production continuity. In addition, at present, most of the impurity removal of potato seeds uses a vibrating screen to remove impurities by generating vibration, so that the soil on the surface of potato seeds cannot be removed thoroughly. Summary of the Invention

[0003] Aiming at the defects existing in the above-mentioned prior art, the present invention provides a potato seed selection device and method to solve the problems of low processing efficiency of existing potato seed selection devices and insufficient impurity removal on the surface of potato seeds.

[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] A potato seed selection device includes: a chassis, including an upper box body and a lower box body disposed below and communicating with the upper box body; an impurity removal cylinder is disposed in the upper box body; a first bottom plate is movably disposed at the bottom of the impurity removal cylinder; an impurity removal device, including: a cleaning column disposed on the first bottom plate; an output mechanism communicating with the impurity removal cylinder; a sorting device disposed in the lower box body, including: a screening structure, with a plurality of grading areas arranged in sequence along the flowing direction of potato seeds; a aligning structure is correspondingly disposed below each grading area; a driving mechanism is drivingly connected to the first bottom plate; a lifting mechanism is drivingly connected to the first bottom plate; wherein, the first bottom plate can be switched between a preset first position and a second position under the drive of the lifting mechanism; when in the first position, the first bottom plate is docked with the bottom of the impurity removal cylinder to close the bottom of the impurity removal cylinder, and the driving mechanism drives the first bottom plate to rotate; when in the second position, the first bottom plate is separated from the impurity removal cylinder to form a feeding channel for potato seeds to pass through.

[0006] The present invention can regulate the on / off of the impurity removal cylinder and the sorting device by controlling the lifting of the first bottom plate through the lifting mechanism. The impurity removal and sorting are integrated, and the feeding and discharging are also integrated, reducing the processing procedures, improving the processing efficiency, and ensuring the continuity of the equipment. Specifically, after the impurity removal is completed, the lifting mechanism drives the first bottom plate to move downward, forming a feeding channel between the first bottom plate and the impurity removal cylinder, so that the seed potatoes directly enter the sorting device. The feeding of the impurity removal cylinder and the feeding of the sorting device are integrated, making the seed selection more convenient and fast, eliminating the intermediate transfer link, significantly improving the processing efficiency, and ensuring the continuity of production. Moreover, the gap between the impurity removal cylinder and the first bottom plate can be flexibly adjusted according to the size of the seed potatoes to ensure smooth feeding. At the same time, by arranging the cleaning columns on the first bottom plate and driving the first bottom plate to rotate by the driving mechanism, the cleaning columns can clean the surface of the seed potatoes in the impurity removal cylinder and can continuously clean the surface of the seed potatoes, so that the soil and other impurities on the surface of the seed potatoes can fall off better. After sorting, the seed potatoes are aligned by the alignment structure, which can avoid the chaos of the seed potato output and is beneficial to improving the accuracy and efficiency of the subsequent processing links.

[0039] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0040] 1. By adjusting the lifting of the first bottom plate through the lifting mechanism, the on-off of the impurity removal cylinder and the sorting device can be regulated. The impurity removal and sorting are integrated, and the loading and unloading are also integrated, reducing the processing procedures, improving the processing efficiency, and ensuring the continuity of the equipment. That is, after the impurity removal is completed, the lifting mechanism drives the first bottom plate to move downward, forming a feeding channel between the first bottom plate and the impurity removal cylinder, so that the seed potatoes directly enter the sorting device. The feeding of the impurity removal cylinder and the feeding of the sorting device are integrated, making the seed selection more convenient and fast, eliminating the intermediate transfer link, significantly improving the processing efficiency, and ensuring the continuity of production. At the same time, the gap between the impurity removal cylinder and the first bottom plate can be flexibly adjusted according to the size of the seed potatoes to ensure smooth feeding.

[0041] 2. By arranging the cleaning column on the first bottom plate and driving the first bottom plate to rotate by the driving mechanism, the surface of the seed potatoes in the impurity removal cylinder can be cleaned, and the surface of the seed potatoes can be continuously cleaned, so that the soil and other impurities on the surface of the seed potatoes can fall off better. At the same time, the impurity removal cylinder rotates synchronously with the first bottom plate, further enhancing the tumbling and friction of the seed potatoes, making the impurity removal of the seed potatoes more thorough and further improving the impurity removal effect.

[0042] 3. By arranging a second bottom plate below the first bottom plate, when the first bottom plate is docked with the impurity removal cylinder, the second bottom plate can be docked with the upper box body, thereby forming a waste discharge channel on the outer periphery of the impurity removal cylinder, enabling the soil and sundries in the impurity removal cylinder to be output outward through the outer periphery of the impurity removal cylinder, improving the output effect of the soil and sundries, and greatly improving the impurity removal efficiency. At the same time, by arranging a movable plate on the inner side of the second bottom plate and a sealing ring on the upper surface of the movable plate, under the action of the first spring, the sealing performance of the waste discharge channel can be ensured, and when feeding after the impurity removal is completed, the first bottom plate can be shaken through the elasticity of the spring to dredge the first waste discharge hole. At the same time, when operating in cooperation with the vibration device, the vibration can be transmitted to the first bottom plate through the first spring, further enhancing the shaking effect, promoting the smooth discharge of the impurities in the first waste discharge hole, and also assisting the seed potatoes to fall quickly to avoid accumulation.

[0043] 4. By arranging a first cavity in the column body to communicate with each other and connecting with a suction fan to form a negative pressure adsorption channel. During the impurity removal process, through the synergistic action of the waste discharge channel on the outer periphery of the impurity removal cylinder and the first cavity (the sundries can not only be discharged from the outer periphery of the impurity removal cylinder, but also be discharged after entering the first cavity), the output effect of the soil and sundries is further improved, ensuring that the surface of the seed potatoes is thoroughly cleaned.

[0044] 5. By adding a second cavity inside the cylinder and inputting a controllable air flow into the second cavity through a hair dryer, after the air flow is ejected from the air blowing holes, on the one hand, it can blow off the stubborn impurities attached to the surface of the seed potatoes, and cooperate with the adsorption effect of the exhaust fan, which can significantly improve the impurity removal effect; on the other hand, by adjusting the wind force, the seed potatoes can be blown to the sorting device after the impurity removal is completed, realizing automatic transportation, reducing mechanical damage, and improving the processing efficiency.

[0045] 6. Through the setting of the alignment structure, the present invention can orderly arrange and evenly space the discharged seed potatoes after sorting, effectively solving the problem of disorderly output materials of traditional equipment, not only ensuring the continuity of the production process, but also providing an ideal material distribution state for subsequent processes such as visual inspection and seed cutting, significantly improving the accuracy and efficiency of subsequent processing links. By integrating impurity removal, cleaning, sorting, and alignment in the same equipment, the entire seed potato selection process becomes more smooth and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0064] Embodiment 1

[0065] AsFigures 1 to 6 As shown in the figure, an embodiment of the present invention provides a potato seed selection device, including a chassis 1, a cleaning device 2, a driving mechanism 3, a lifting mechanism 4 and a sorting device 5.

[0066] The chassis 1 includes an upper box body 1a and a lower box body 1b which is arranged below the upper box body 1a and communicated with it.

[0067] A cleaning cylinder 11 and a first bottom plate 12 are arranged in the chassis 1.

[0068] The cleaning cylinder 11 is rotatably arranged in the upper box body 1a. Both the top and bottom of the cleaning cylinder 11 are open to form a feed end and a discharge end. The top feed end is communicated with a feed port 11a arranged at the top of the cleaning cylinder 11. The first bottom plate 12 is movably arranged at the bottom discharge end of the cleaning cylinder 11. The driving mechanism 3 is drivingly connected to the first bottom plate 12 and can drive the first bottom plate 12 to rotate. The lifting mechanism 4 is drivingly connected to the first bottom plate 12 and can drive the first bottom plate 12 to perform a vertical lifting movement. The lifting mechanism 4 can move the first bottom plate 12 from a predetermined first position to a second position, that is, the first bottom plate 12 can approach or move away from the cleaning cylinder 11 under the drive of the lifting mechanism 4. When the first bottom plate 12 approaches the cleaning cylinder 11 and docks with it, it is connected to the cleaning cylinder 11 through a connecting member 6 and closes the discharge end at the bottom of the cleaning cylinder 11. When it moves away from the cleaning cylinder 11, the closure of the bottom of the cleaning cylinder 11 is released.

[0069] The cleaning device 2 includes a cleaning column 21 arranged on the first bottom plate 12 for cleaning the soil and sundries on the surface of the potato seeds and an output mechanism for outputting impurities such as soil.

[0070] The sorting device 5 is arranged in the lower box body 1b and is located outside the first bottom plate 12, and is used to receive the cleaned potato seeds and perform a grading operation on the potato seeds. The sorting device 5 includes a screening structure 51 and an aligning structure 52. The screening structure 51 has a plurality of grading areas with different specifications. The grading specifications of the grading areas are gradually arranged from small to large from the feed end of the potato seeds to the other end. A corresponding aligning structure 52 is arranged below each grading area.

[0071] As an implementation scenario, in this scenario, the driving mechanism 3 is arranged below the first bottom plate 12, and its power output end is drivingly connected to the first bottom plate 12 to drive the first bottom plate 12 to rotate. The movable end of the lifting mechanism 4 is connected to the bottom of the driving mechanism 3 to drive the driving mechanism 3 and the first bottom plate 12 to rise or fall. During use, when the lifting mechanism 4 drives the first bottom plate 12 to move upward, the first bottom plate 12 can be docked with the impurity removal cylinder 11. After the docking is completed, potato seeds are put into the impurity removal cylinder 11, and then the driving mechanism 3 is started. The first bottom plate 12 rotates under the drive of the driving mechanism 3, and the impurity removal cylinder 11 rotates synchronously with the first bottom plate 12 under the action of the connecting member 6. As a result, the cleaning columns 21 provided on the first bottom plate 12 clean the surface of the potato seeds in the impurity removal cylinder 11, causing the soil and other impurities on the surface of the potato seeds to fall off. The cleaned soil and other impurities are discharged through the output mechanism. After impurity removal, the lifting mechanism 4 drives the first bottom plate 12 to move downward, separating the first bottom plate 12 from the impurity removal cylinder 11. As a result, a gap is formed between the impurity removal cylinder 11 and the first bottom plate 12, and this gap forms a feeding channel for the potato seeds to enter the sorting device 5. The sorting device 5 receives the potato seeds discharged from the feeding channel and performs a grading operation on the potato seeds. By rotating the cleaning columns 21 with the first bottom plate 12, under the action of the cleaning columns 21, the soil and other impurities on the surface of the potato seeds can fall off better. After impurity removal, by moving the first bottom plate 12 downward, the potato seeds can be introduced into the sorting device 5, making the feeding of the impurity removal cylinder 11 and the feeding of the sorting device 5 more convenient and fast, reducing the processing procedures, improving the processing efficiency, and ensuring the continuity of the equipment. At the same time, the gap between the impurity removal cylinder 11 and the first bottom plate 12 is adjustable, so that the potato seeds can be smoothly discharged, reducing the risk of blockage during feeding. The potato seeds entering the sorting device 5 are first graded by the screening structure 51 and then arranged in an orderly manner by the alignment structure 52, avoiding chaos when the potato seeds are discharged and facilitating subsequent processing operations, improving the seed selection accuracy. By integrating the four core functions of impurity removal, cleaning, sorting, and alignment into one device, the processing of potato seeds is made more convenient and efficient.

[0072] In one embodiment, a filter box may also be connected to the feed inlet of the upper box body 1a. A filter screen is arranged in the filter box. Before the potato seeds are put into the impurity removal cylinder 11, they are first preliminarily filtered through the filter screen to preliminarily filter out the sundries in the potato seeds and exclude the too small potato seeds.

[0073] In one embodiment, the output mechanism includes a suction fan connected to the inside of the impurity removal cylinder 11. Under the action of the suction fan, the soil and sundries in the impurity removal cylinder 11 are drawn out.

[0074] Embodiment 2

[0075] The embodiment of the present invention application provides a potato seed selection device. On the basis of Embodiment 1, in this embodiment, a second bottom plate 13 is further arranged in the chassis 1.

[0076] The second bottom plate 13 is arranged below the first bottom plate 12, and the second bottom plate 13 can move vertically up and down synchronously with the first bottom plate 12.

[0077] The bottom of the upper box body 1a extends into the lower box body 1b, that is, a first extension part 12a is formed at the lower part of the upper box body 1a and the upper part of the lower box body 1b. When the first bottom plate 12 is docked with the impurity removal cylinder 11, the second bottom plate 13 is docked with the bottom of the first extension part 12a, so as to form a closed space for the upper box body 1a as well. Specifically, the size of the first bottom plate 12 is adapted to the impurity removal cylinder 11, and the size is smaller than the opening at the lower end of the upper box body 1a. The first bottom plate 12 can move in and out within the upper box body 1a. The size of the second bottom plate 13 is larger than that of the first bottom plate 12, the size of the second bottom plate 13 is larger than or equal to the size of the upper box body 1a, and a groove body 130 is arranged on the inner side of the second bottom plate 13. When the first bottom plate 12 is docked with the impurity removal cylinder 11 and the second bottom plate 13 is docked with the upper box body 1a, the groove body 130 can be communicated with the gap between the outer wall of the impurity removal cylinder 11 and the inner wall of the upper box body 1a, so as to form an interconnected impurity discharge channel outside the impurity removal cylinder 11.

[0078] Furthermore, a plurality of first impurity discharge holes 121 are circumferentially distributed on the first bottom plate 12 and the impurity removal cylinder 11, so that the inside of the impurity removal cylinder 11 is communicated with the impurity discharge channel through the plurality of first impurity discharge holes 121.

[0079] In this embodiment, the impurity removal device 2 includes a plurality of flexible cleaning columns 21 and a soil and impurity output mechanism.

[0080] The cleaning columns 21 are fixed on the first bottom plate 12 and can clean the soil and impurities on the surface of the seed potatoes.

[0081] The output mechanism includes a suction fan, an impurity discharge pipe 22 and a telescopic pipe 23. The input end of the suction fan is connected to the impurity discharge pipe 22, the impurity discharge pipe 22 is connected to one end of the telescopic pipe 23, and the other end of the telescopic pipe 23 penetrates through the second bottom plate 13 and is communicated with the groove body 130. Thus, when the second bottom plate 13 is docked with the upper box body 1a, under the action of the suction fan, the soil and impurities in the impurity removal cylinder 11 enter the impurity discharge channel through a plurality of first impurity discharge holes 121, then enter the telescopic pipe 23 and then enter the impurity discharge pipe 22, and finally are collected by a collection device connected to the output end of the suction fan. In this embodiment, the soil and impurities in the impurity removal cylinder 11 can be output outward through the outer periphery of the impurity removal cylinder 11, which is beneficial to improving the output effect of the soil and impurities and improving the impurity removal efficiency.

[0082] In an implementation manner, a baffle 131 is arranged on the upper surface of the second bottom plate 13, a movable plate 132 is movably arranged inside the baffle 131, the position of the movable plate 132 corresponds to the position of the upper box body 1a, a through hole 1321 is formed in the middle of the movable plate 132, and a first spring 133 is arranged between the bottom of the movable plate 132 outside the through hole 1321 and the second bottom plate 13.

[0083] Optionally, a sealing ring 134 is provided on the upper surface of the movable plate 132.

[0084] During use, when the second bottom plate 13 moves upward driven by the lifting mechanism 4, the sealing ring 134 above the second bottom plate 13 is butted against the first extension portion 12a of the upper box body 1a. Under the action of the first spring 133, the sealing ring 134 can closely fit against the bottom of the upper box body 1a, thereby forming a sealed space for the impurity discharge channel and further improving the impurity removal effect. At the same time, when the second bottom plate 13 moves downward driven by the lifting mechanism 4, the first spring 133 loses pressure, so that the movable plate 132 can move upward under the action of the first spring 133, and thus the sealing ring 134 can fit against the lower surface of the first bottom plate 12. In this way, the first spring 133 can generate a certain vibration on the first bottom plate 12, thereby dredging the first impurity discharge holes 121 and reducing blockage. Moreover, when vibrating discharging is adopted after impurity removal is completed, the vibration effect can be improved in cooperation with the first spring 133.

[0085] In one embodiment, a telescopic plate 135 is further provided on the side of the first spring 133 away from the baffle 131. The telescopic plate 135 can extend or contract along with the movement of the movable plate 132. By providing the telescopic plate 135, the supporting effect on the movable plate 132 can be improved. Exemplarily, the telescopic plate 135 can adopt the structure of a fixed plate and a telescopic plate, that is, the fixed plate is fixed on the second bottom plate 13, the telescopic plate is inserted into the fixed plate and is in sliding fit with it, and the bottom of the telescopic plate is connected to the inner bottom surface of the fixed plate through a second spring. By cooperating the second spring with the first spring 133, when the movable plate 132 is butted against the upper box body 1a, the sealing effect can be further improved, and when the movable plate 132 is away from the upper box body 1a, the movable plate 132 can be better pushed to fit against the lower surface of the first bottom plate 12 by the restoring forces of the first spring 133 and the second spring.

[0086] During use, when the lifting mechanism 4 drives the bottom plate to move upward, the first bottom plate 12 can be docked with the impurity removal cylinder 11. After the docking is completed, seed potatoes are put into the impurity removal cylinder 11, and then the driving mechanism 3 is started. The first bottom plate 12 rotates under the drive of the driving mechanism 3, and the impurity removal cylinder 11 rotates synchronously with the first bottom plate 12 under the action of the connecting member 6. As a result, the cleaning columns 21 provided on the first bottom plate 12 clean the surface of the seed potatoes in the impurity removal cylinder 11, causing impurities such as soil on the surface of the seed potatoes to fall off. The cleaned soil and other impurities enter the impurity discharge channel through a number of first impurity discharge holes 121 under the action of the exhaust fan, and then are discharged to a designated position through the telescopic pipe 23 and the impurity discharge pipe 22 in sequence. After impurity removal is completed, the lifting mechanism 4 drives the first bottom plate 12 and the second bottom plate 13 to move downward, and the first bottom plate 12 is separated from the impurity removal cylinder 11. As a result, gaps are formed between the impurity removal cylinder 11 and the first bottom plate 12, and between the second bottom plate 13 and the upper box body 1a. These gaps form a feeding channel for the seed potatoes to enter the sorting device 5. The sorting device 5 is arranged outside the second bottom plate 13 and is used to receive the seed potatoes discharged from the feeding channel and perform a grading operation on the seed potatoes.

[0087] As an implementation scenario, in this scenario, the driving mechanism 3 is installed at the bottom of the second bottom plate 13, and its power output end is connected to the first bottom plate 12 to drive the first bottom plate 12 to rotate. The movable end of the lifting mechanism 4 is connected to the driving mechanism 3 or the second bottom plate 13, and can drive the second bottom plate 13 and the driving mechanism 3 and the first bottom plate 12 on the second bottom plate 13 to perform vertical lifting movement. Exemplarily, the driving mechanism 3 includes a driving motor and a driving shaft. One end of the driving shaft is connected to the power output end of the driving motor, and the other end passes through the second bottom plate 13 and is connected to the bottom of the first bottom plate 12. The middle position of the second bottom plate 13 is sleeved on the driving shaft and is mechanically sealed with it. The lifting mechanism 4 is installed at the bottom of the lower box body 1b, and its movable end is connected to the driving motor.

[0088] As an implementation scenario, referring to the attached Figure 1 and Figure 2 shown, a limiting rod 14 is further provided in the chassis 1. The limiting rod 14 is connected to the inner wall of the top of the lower box body 1b. The second bottom plate 13 extends outward with a second extension portion 13a. The limiting rod 14 is arranged above the second extension portion 13a, and its position corresponds to that of the second extension portion 13a. Through the setting of the limiting rod 14, during use, when the lifting mechanism 4 drives the driving mechanism 3 to move upward to dock the first bottom plate 12 with the impurity removal cylinder 11, the limiting rod 14 can limit the second bottom plate 13 so that the second bottom plate 13 does not rotate, while the first bottom plate 12 rotates under the drive of the driving mechanism 3, and the impurity removal cylinder 11 rotates synchronously with the first bottom plate 12 under the action of the connecting member 6. As a result, the cleaning columns 21 provided on the first bottom plate 12 can clean the surface of the seed potatoes in the impurity removal cylinder 11, causing impurities such as soil on the surface of the seed potatoes to fall off.

[0089] Optionally, the limiting rod 14 can adopt a sliding-fit cylinder and rod. The cylinder is fixed to the inner wall of the lower box body 1b, one end of the rod is slidably arranged inside the cylinder, and the other end is connected to the second extension part 13a. When the second bottom plate 13 moves away from the upper box body 1a driven by the lifting mechanism 4, the rod can extend out of the cylinder, and the overall length of the limiting rod 14 increases. When the second bottom plate 13 rises and docks with the upper box body 1a, the rod is inserted into the cylinder, and the overall length of the limiting rod shortens. Of course, the limiting rod 14 can also adopt an integral rod structure and be directly fixed above the second extension part 13a.

[0090] Embodiment 3

[0091] The embodiment of the present invention application provides a potato seed selection device. On the basis of Embodiment 2, in this embodiment, the cleaning column 21 includes a column body 211 and a cleaning layer 212 arranged on the outer wall of the column body 211.

[0092] The column body 211 has a first cavity 2111 inside. Second impurity discharge holes 2112 are opened at the bottom of the column body 211 and the bottom of the first bottom plate 12. A plurality of third impurity discharge holes 2113 communicating with the first cavity 2111 are arranged on the column body 211. The first cavity 2111 communicates with the trough 130 below the first bottom plate 12 through the second impurity discharge holes 2112, that is: when the first bottom plate 12 is docked with the impurity removal cylinder 11, the first cavity 2111 communicates with the impurity removal channel formed on the outer periphery of the impurity removal cylinder 11 through the second impurity discharge holes 2112. Since the impurity removal channel communicates with the first cavity 2111, when the exhaust fan is enabled, the sundries can not only be discharged from the outer periphery of the impurity removal cylinder 11, but also be discharged after entering the first cavity inside the column body 211. When the cleaning layer 212 cleans the surface of the seeds, part of the dust and sundries can be timely discharged through the third impurity discharge holes 2113, that is, the dust and sundries enter the first cavity 2111 through the third impurity discharge holes 2113, then enter the trough 130 through the second impurity discharge holes 2112, and then enter the telescopic pipe 23.

[0093] Embodiment 4

[0094] The embodiment of the present invention application provides a potato seed selection device. On the basis of Embodiment 3, a second cavity 2114 is further arranged inside the column body 211. The second cavity 2114 is formed by a partition plate arranged inside the column body 211, that is, a partition plate is arranged in the inner cavity of the column body 211, and this partition plate divides the cavity into a first cavity 2111 and a second cavity 2114.

[0095] Optionally, the second cavity 2114 is located outside the first cavity 2111, and the third row of impurity removal holes 2113 communicating with the first cavity 2111 are formed through an impurity removal pipeline, that is: an impurity removal pipeline is communicatively provided on the first cavity 2111, and one end of the impurity removal pipeline away from the first cavity 2111 passes through the second cavity 2114 and the cleaning layer 212 to communicate with the inside of the impurity removal cylinder 11.

[0096] Further, a plurality of air blowing holes 2115 communicating with the second cavity 2114 are provided on the outer wall of the cylinder 211. The air blowing holes 2115 penetrate through the cleaning layer 212 and face the inner wall direction of the impurity removal cylinder 11. The second cavity 2114 is communicatively connected with a hair dryer through an air outlet pipe 24. During use, by starting the hair dryer, the hair dryer inputs air flow into the second cavity 2114 through the air outlet pipe 24, and the air flow blows out through the air blowing holes 2115. On the one hand, the impurities attached to the surface of the seed potato can be blown off, and with the cooperation of the suction fan, the impurity removal effect can be further improved. On the other hand, by adjusting the wind force of the hair dryer, after the impurity removal of the seed potato is completed, the seed potato can be blown to the sorting device 5 to complete the feeding and loading of the seed potato.

[0097] Optionally, a movable baffle 25 is provided in the air blowing hole 2115. One end of the movable baffle 25 is connected with a connecting plate 27 through a connecting rod 26, and a third spring 28 is sleeved on the connecting rod 26 between the connecting plate 27 and the inner wall of the second cavity 2114. The air blowing hole 2115 is gradually expanded from one end of the second cavity 2114 to the outer end. The movable baffle 25 is located in the air blowing hole 2115 and is adapted to it. In the natural state of the third spring 28, the movable baffle 25 is located at the small end of the air blowing hole 2115 and closes it. When the hair dryer is enabled, the movable baffle 25 will move towards the large end of the outer side of the air blowing hole 2115 under the action of the air flow, so that the outside of the second cavity 2114 is communicatively connected. In this embodiment, during use, the air blowing hole 2115 can be enlarged. When the air blowing force is increased, the seed potato can be better blown to the sorting device 5. Through the setting of the movable baffle 25, it can be avoided that the seed potato enters the second cavity 2114 from the air blowing hole 2115 when the hair dryer is not enabled during the impurity removal process.

[0098] In order to match the setting of the movable baffle 25, the depth of the air blowing hole 2115 can be deepened. Optionally, the cleaning layer 212 can be a rubber layer and a sponge layer or a brush. The rubber layer is provided on the outer wall of the cylinder 211, and the sponge layer or the brush is provided outside the rubber layer as a contact layer in contact with the seed potato. The air blowing hole 2115 extends to the rubber layer or the rubber layer and the sponge layer, and the movable baffle 25 can be located in the rubber layer.

[0099] Optionally, a cleaning layer is also provided on the inner wall of the impurity removal cylinder 11 corresponding to the cleaning column 21.

[0100] Optionally, a flexible arc-shaped protrusion 213 is further provided at the upper end of the cylinder 211.

[0101] As an implementation scenario, in this scenario, a vertical plate 15 is provided below the second bottom plate 13. When the second bottom plate 13 moves downward away from the impurity removal cylinder 11, its bottom contacts the vertical plate 15. Thus, the second bottom plate 13, the vertical plate 15, and the bottom wall of the lower box body 1b enclose an equipment installation room inside the lower box body 1b, and the outside of the vertical plate 15 is a sorting chamber, and the sorting device 5 is arranged in the sorting chamber.

[0102] Optionally, the telescopic pipe 23 is arranged in the equipment installation room. One end of the impurity discharge pipe 22 is connected to the telescopic pipe 23, and the other end extends to the outside of the equipment installation room and is connected to the exhaust fan.

[0103] Optionally, the driving mechanism 3 and the lifting mechanism 4 are installed in the equipment installation room.

[0104] Optionally, an air inlet cavity 29 is further arranged in the equipment installation room. A joint is arranged on the air inlet cavity 29, and the position of the joint corresponds to the position of the air outlet pipe 24. And the air outlet pipe 24 can be movably and sealingly inserted into the joint. That is, one end of the air outlet pipe 24 penetrates through the first bottom plate 12 and is connected to the bottom of the column body 211, and the other end penetrates through the second bottom plate 13 and extends below the second bottom plate 13. The air outlet pipe 24 can be rotationally matched with the second bottom plate 13 through a sealing bearing. The output end of the hair dryer is connected to the air inlet cavity 29 through a pipeline. When in use, when the air outlet pipe 24 moves upward with the first bottom plate 12, the air outlet pipe 24 disengages from the joint on the air inlet cavity 29. When the first bottom plate 12 moves downward to the upper end of the vertical plate 15, the air outlet pipe 24 is sealingly inserted into the joint. At this time, by starting the hair dryer, the air flow enters the second cavity 2114 through the air inlet cavity 29 and the air outlet pipe 24 and is blown out from the air blowing holes 2115 to blow the potato seeds to the sorting device 5.

[0105] As another implementation scenario, in this scenario, the part of the air outlet pipe 24 located below the second bottom plate 13 can directly adopt a telescopic air outlet pipe.

[0106] When in use, some or all of the cleaning columns can adopt the structure described in this embodiment. Preferably, the cleaning column 21 located in the middle of the impurity removal cylinder 11 adopts the above structure.

[0107] Embodiment 5

[0108] The embodiment of the present invention application provides a potato seed selection device. On the basis of Embodiment 4, a feeding component 7 is further arranged on the upper part of the impurity removal cylinder 11.

[0109] Two feeding ports 11a are respectively arranged on both sides of the top of the upper box body 1a. The feeding component 7 is correspondingly arranged in the impurity removal cylinder 11 below the feeding ports 11a.

[0110] The material guiding assembly 7 includes a material guiding plate 71 and a fourth spring 72. One end of the material guiding plate 71 is hinged to the inner wall of the impurity removing cylinder 11. The fourth spring 72 is arranged between the middle position at the bottom of the material guiding plate 71 and the inner wall of the impurity removing cylinder 11. One end of the fourth spring 72 is connected to the inner wall of the impurity removing cylinder 11, and the other end is connected to the material guiding plate 71. Through the arrangement of the material guiding plate 71, the input potato seeds can be buffered to avoid damage to the potato seeds caused by too high a drop during feeding.

[0111] Optionally, the cleaning column 21 is arranged at the middle position of the impurity removing cylinder 11, and a flexible arc-shaped protrusion 213 is also arranged at the upper end of the column body 211 of the cleaning column 21. In this way, when the potato seeds are fed, they are first buffered by the material guiding plate 71 and then fall onto the arc-shaped protrusion 213 for further buffering. On the one hand, the buffering effect can be further improved. On the other hand, after passing through the arc-shaped protrusion 213, the potato seeds will slide down from the outside and thus enter between the two cleaning columns 21, so as to facilitate the cleaning layer 212 to clean the surface of the potato seeds and improve the cleaning effect.

[0112] In an embodiment, the material guiding assembly 7 further includes an airbag 73. The airbag 73 is arranged between the material guiding plate 71 and the inner wall of the impurity removing cylinder 11. By inflating or deflating the airbag 73, the inclination of the material guiding plate 71 can be adjusted, which is convenient for use.

[0113] Embodiment 6

[0114] The embodiment of the present invention provides a potato seed selection device. On the basis of any of the above embodiments, in this embodiment, a notch 111 is opened at the bottom of the impurity removing cylinder 11, and the connecting member 6 includes a first magnet 61 and a second magnet 62.

[0115] Specifically, the first magnet 61 is fixed on the first bottom plate 12 and the position corresponds to the notch 111. The first magnet 61 adopts a columnar structure, and the notch 111 is adapted to the first magnet 61. The first magnet 61 can be movably inserted into the notch 111. The second magnet 62 is movably arranged in the notch 111 through a connecting rope 63. The second magnet 62 is slidably matched with the inner wall of the notch 111, and the length of the connecting rope 63 is less than the depth of the notch 111.

[0116] Optionally, the lower end of the impurity removing cylinder 11 is thickened, and the notch 111 is opened in the thickened part.

[0117] During use, when the first base plate 12 moves upward driven by the lifting mechanism 4, the first magnet 61 on the first base plate 12 is inserted into the notch 111, thereby fixing the relative positions of the first base plate 12 and the impurity removal cylinder 11, so that the driving shaft of the driving mechanism 3 can drive the impurity removal cylinder 11 to rotate when it rotates. At the same time, by setting the connected cylinder as a magnet and arranging a matching second magnet 62 in the notch 111, on the one hand, the stability of the connection between the impurity removal cylinder 11 and the first base plate 12 can be enhanced, and on the other hand, it is also convenient for the first base plate 12 and the second base plate 13 to reset, that is: when the first base plate 12 moves upward, the first magnet 61 is attracted by the second magnet 62 (the second magnet 62 can slide out of the notch 111), thereby driving the first base plate 12 to rotate, so that the first magnet 61 is located below the notch 111 and can be smoothly inserted into the notch 111. Of course, the reset of the first base plate 12 can also be performed by the driving mechanism 3, that is: the initial position of the first base plate 12 is set such that the first magnet 61 is directly below the notch 111, and when the driving mechanism 3 drives the first base plate 12 to rotate, it will automatically return to the initial position.

[0118] As an implementation scenario, in this scenario, both the impurity removal cylinder 11 and the first base plate 12 adopt circular structures, and two or four feeding channels can be formed below the upper box body 1a. The two or four feeding channels are respectively connected to a sorting chamber, and sorting devices 5 are arranged in the sorting chambers. For example, sorting chambers are respectively arranged on the left and right sides at the bottom of the upper box body 1a, and baffle structures are arranged on the front and back sides of the upper box body 1a. When the impurity removal cylinder 11 feeds, the potato seeds can only enter the sorting devices 5 on both sides through the feeding channels on the left and right sides. Correspondingly, when the air blowing holes 2115 are arranged, their blowing directions are towards the feeding channels on the left and right sides. Of course, sorting chambers can also be arranged around the front, back, left, and right sides at the bottom of the upper box body 1a.

[0119] Example 7

[0120] The embodiment of the present invention application provides a potato seed sorting device. On the basis of any of the above embodiments, in this embodiment, the sorting device 5 includes a screening structure 51 and an aligning structure 52. The screening structure 51 has multiple grading areas with different specifications, and the grading specifications of the grading areas gradually increase from the feeding end of the potato seeds to the other end. A set of aligning structures 52 is respectively arranged below each grading area.

[0121] In this embodiment, the screening structure 51 includes a sieve plate 511. The sieve plate 511 has multiple grading areas. Exemplarily, the sieve plate 511 includes a first grading area 51a, a second grading area 51b, and a third grading area 51c, and the sieve holes of the sieve plate 511 are arranged from small to large from one side of the feeding channel to the other side. A discharge area is provided on the side of the third grading area 51c away from the second grading area 51b. A set of aligning structures 52 is respectively arranged below the three grading areas.

[0122] Optionally, a retaining bar 5111 is provided between adjacent grading areas, and one side of the retaining bar 5111 is arranged in an inward concave arc, that is: a retaining bar 5111 is respectively provided between the first grading area 51a and the second grading area 51b, and between the second grading area 51b and the third grading area 51c. Through the setting of the retaining bar, the seed potatoes can be blocked to a certain extent during grading, increasing the time for the seed potatoes to stay on the grading area and improving the grading effect.

[0123] Optionally, the potato seed potato selection device further includes a vibration device 8. The vibration device 8 can be installed on the vertical plate 15 and is used to generate vibrations for the screening structure 51 or the screening structure 51 and the second bottom plate 13. By generating vibrations for the second bottom plate 13 through the vibration device 8 and cooperating with the air blowing holes 2115, the smoothness of the seed potato feeding can be further ensured. By generating vibrations for the screening structure 51 through the vibration device 8, the grading efficiency can be improved. When the vibration device 8 generates vibrations for the second bottom plate 13, the vibrations can be transmitted to the first bottom plate 12 through the first spring 133, further improving the feeding effect and the dredging effect of the first waste discharge holes 121. The vibration device 8 is a prior art, such as a vibration motor, and its implementation process and working principle will not be described here.

[0124] During use, after the seed potatoes are decontaminated in the decontamination cylinder 11, they first enter the first grading area 51a from the feeding channel. Under the action of the vibration device 8, the smaller-sized seed potatoes fall into the lower set of alignment structures 52 through the first grading area 51a, the medium-sized seed potatoes fall into the lower set of alignment structures 52 through the second grading area 51b, the larger-sized seed potatoes fall into the lower set of alignment structures 52 through the third grading area 51c, and the extra-large-sized seed potatoes are discharged from the discharging area. In one embodiment, the seed potatoes discharged from the discharging area can also be made to fall into the alignment structure 52 by setting a set of alignment structures.

[0125] Example 8

[0126] The embodiment of the present invention application provides a potato seed potato selection device, as Figure 7 shown. In this embodiment, the sorting device 5 includes a screening structure 51 and an alignment structure 52. The screening structure 51 has a plurality of grading areas with different specifications, and a set of alignment structures 52 is respectively arranged corresponding to the lower part of each grading area.

[0127] In this embodiment, the screening structure 51 includes a first inclined plate 512 and a plurality of second inclined plates 513. The high end of the first inclined plate 512 is connected to the side wall of the vertical plate 15, and the other end is connected to the top of the hopper of the alignment structure 52. The plurality of second inclined plates 513 are arranged at intervals on one side of the first inclined plate 512, and their low ends are respectively connected to the corresponding hopper tops. The second inclined plates 513 are hinged to the hopper tops and / or round rods 514 are respectively telescopically arranged at the high ends of the second inclined plates 513. By rotatably arranging the second inclined plates 513 or telescopically arranging the round rods 514 at the upper ends, the gap between adjacent inclined plates can be adjusted. Thus, during use, it can be adaptively adjusted according to the classification requirements.

[0128] Optionally, the upper end of the second inclined plate 513 is provided with a rounded corner.

[0129] Optionally, the upper end of the second inclined plate 513 forms a stepped structure downward in sequence from one end to the other end of the first inclined plate 512.

[0130] As an implementation scenario, in this scenario, the second inclined plate 513 is rotatably connected to the hopper top through a rotating shaft. When the second inclined plate 513 is adjusted to the required inclination angle, it can be fixed through a fastener.

[0131] As an implementation scenario, in this scenario, round rods 514 are respectively telescopically arranged at the high ends of the second inclined plates 513. The round rods 514 can be retracted into the second inclined plates 513 or extended out of the second inclined plates 513, so that the gap between adjacent inclined plates can be adjusted.

[0132] Specifically, a plurality of second inclined plates 513 spaced apart on the outside of the first inclined plate 512 form a first classification area 51a, a second classification area 51b, a third classification area 51c, and a discharging area 51d above the alignment structure 52. By adjusting the extended length of the round rods 514, the sizes of the first, second, and third classification areas are adjusted. Exemplarily, all the round rods close to the first inclined plate 512 are extended, so as to form a smaller material distribution opening with the first inclined plate 512; the round rods in the middle are extended by a part, so as to form a medium-sized material distribution opening with the adjacent second inclined plate; the round rods far from the first inclined plate are not extended, so as to form a larger material distribution opening with the adjacent inclined plate.

[0133] Optionally, the round rod 514 is connected to the second inclined plate 513 through a plug board. Specifically, a slot is opened at the upper end of the second inclined plate 513, and the plug board is inserted into the slot. Optionally, the plug board is made of rubber material and is connected to the slot by extrusion. During use, the plug board can be pulled out of the slot or inserted into the slot by applying a pulling force or a pushing force to the plug board.

[0134] During use, first open the box door of the sorting chamber, and then adjust the inclination of the second inclined plate 513 and / or the protruding length of the round rod 514. After the seed potatoes are cleaned in the cleaning cylinder 11, the seed potatoes first enter the first grading area 51a from the feeding channel. The smaller-sized seed potatoes fall into a set of alignment structures 52 below through the first grading area 51a, and the remaining seed potatoes continue to roll downward through the arrangement of the stepped structure and the action of the vibration device 8. Thus, the medium-sized seed potatoes fall into a set of alignment structures 52 below through the second grading area 51b, the larger-sized seed potatoes fall into a set of alignment structures 52 below through the third grading area 51c, and the extra-large-sized seed potatoes are discharged from the discharging area 51d. In one embodiment, a set of alignment structures 52 is also added below the discharging area 51d, so that the seed potatoes discharged from the discharging area 51d also fall into the alignment structures for alignment.

[0135] The screening structure 51 provided in this embodiment, compared with the fixed sieve plate in Embodiment 7, can adjust each grading area according to different grading requirements during use, making it more flexible and convenient to use and having a wide application range. It should be noted that in the drawings, the setting position of the inclined plate, its inclination angle, and the spacing distance between adjacent inclined plates are all schematic, only used for expressing the idea of this technical solution and not involving the limitation of the specific position in the actual embodiment.

[0136] Embodiment 9

[0137] The embodiment of the present invention application provides a potato seed potato selection device. Refer to Figures 1 to 6 As shown, in this embodiment, the sorting device 5 includes a screening structure 51 and an alignment structure 52. The screening structure 51 has multiple grading areas with different specifications, and a set of alignment structures 52 is respectively arranged corresponding to the lower part of each grading area.

[0138] Furthermore, the alignment structure 52 includes a hopper 521, a material roller 522, and a motor.

[0139] The hopper 521 includes a material receiving part 521a and a material discharging part 521b that are connected and communicate with each other. The upper end of the material receiving part 521a is open and docked with the corresponding grading area to receive the seed potatoes falling from the material distribution area. The cross-section of the material discharging part 521b is a circular structure. The material roller 522 is adapted to the structure of the material discharging part 521b and is installed in the material discharging part 521b, and a discharge port 5211 is provided at the bottom end of the material discharging part 521b.

[0140] The size of the material roller 522 is adapted to the size of the material discharging part 521b, and a material groove 5221 is opened on its outer wall. The motor is drivingly connected to the material roller 522, and the motor can drive the material roller 522 to rotate slowly.

[0141] During use, when the feed trough 5221 is located below the material receiving portion 521a and communicates with it, the seed potatoes in the material receiving portion 521a fall into the feed trough 5221. The feed roller 522 continues to rotate driven by the motor. When the feed trough 5221 moves to the discharge port 5211, the seed potatoes are discharged from the discharge port 5211.

[0142] As an implementation scenario, in this scenario, the feed trough 5221 is a relatively long feed trough, that is, the feed trough 5221 is opened along the length direction of the feed roller 522, and its length is basically equal to the length of the feed roller.

[0143] As another implementation scenario, in this scenario, referring to Figure 5 As shown, there are multiple feed troughs 5221. The multiple feed troughs 5221 are spaced apart along the length direction of the feed roller 522, and the size of the feed trough 5221 is adapted to one seed potato. In this way, when the seed potatoes fall from the material receiving portion 521a, they will respectively correspond to one feed trough 5221. That is, when the seed potatoes are discharged, there is a gap between adjacent seed potatoes, and the gap is fixed and unchanged. This can facilitate the processing operations of the next process.

[0144] In one implementation manner, the sizes of all the feed troughs 5221 can be set uniformly according to the largest seed potato to be accommodated. In another implementation manner, the feed troughs on each group of feed rollers 522 are respectively matched with the corresponding grading areas. For example, the size of the feed trough below the first grading area is smaller to accommodate the seed potatoes falling from the first grading area, the size of the feed bin below the second grading area is medium to accommodate the seed potatoes falling from the second grading area, and the size of the feed trough below the third grading area is larger to accommodate the seed potatoes falling from the third grading area.

[0145] In one implementation manner, a conveying device 9 is arranged below the discharge port 5211. After the seed potatoes are discharged from the discharge port 5211, they can be conveyed to the next process, such as visual inspection, seed cutting and other processes. When setting, the feeding speed of the feed roller 522 needs to be adapted to the conveying device 9 below, and can be adjusted through a control system, such as intermittent starting of the motor or slow rotation of the feed roller 522, with the criterion that the seed potatoes falling from the feed trough 5221 are conveyed away before the next group of seed potatoes are put in.

[0146] Optionally, the conveying device 9 is located below the chassis 1, that is: a discharge channel 11b is opened at the bottom of the chassis below the discharge port 5211, and the conveying device 9 is arranged below the discharge channel 11b. The conveying device 9 conveys the aligned seed potatoes to the next process.

[0147] Optionally, a group of conveying devices 9 are respectively arranged corresponding to the lower part of each group of alignment structures 52, that is, a conveying device 9 is respectively arranged below each discharge port 5211.

If a black area is recognized on the potato seed, it is determined as unqualified. At this time, the control system adjusts the rejection device 92 to start, so as to reject the unqualified potato seeds into the recycling bin 93.

[0150] As an implementation scenario, in this scenario, a seed cutting device 94 is further provided at the rear end of the rejection device 92, and the seed cutting device 94 is used to cut the potato seeds. That is to say, after the potato seeds are decontaminated and aligned, they enter the conveying device 9, and a visual detection device 91, a rejection device 92, and a seed cutting device 94 are sequentially arranged along the traveling direction of the conveying device 9. The visual detection device 91, the rejection device 92, and the seed cutting device 94 all adopt existing technologies.
