Description

Technical Field

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

[0002] In the processing of potato seed potatoes, impurity removal and sorting are key pretreatment steps, which directly affect the storage quality of seed potatoes and subsequent planting results. Traditional seed potato processing equipment usually separates impurities removal and sorting, that is, first remove dirt, stones and other impurities on the surface of the seed potatoes through impurity removal equipment, and then use sorting devices to grade the size or quality of the seed potatoes. This separate processing method has a long process and low efficiency. For example, after the impurities are removed, the seed potatoes need to be transported to the sorting device manually or by a conveyor device. The unloading of impurities and the loading of sorting require back and forth operations, which reduces the processing efficiency and affects the continuity of production. In addition, at present, most seed potato impurities are removed by vibrating screens, which use the vibration generated to remove impurities, so that the soil on the surface of the seed potatoes is not completely removed. Summary of the invention

[0003] In view of the defects of the above-mentioned prior art, the present invention provides a potato seed potato selection device and method to solve the problems that the existing potato seed potato selection equipment has low processing efficiency and the impurities on the surface of the seed potatoes are not thoroughly removed.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows: A potato seed selection device comprises: a chassis, comprising an upper box body and a lower box body arranged below the upper box body and connected thereto; a debris removal barrel is arranged in the upper box body; a first bottom plate is movably arranged at the bottom of the debris removal barrel; a debris removal device comprises: a cleaning column arranged on the first bottom plate; an output mechanism, connected to the debris removal barrel; a sorting device, arranged in the lower box body, comprising: a screening structure, a plurality of grading areas are arranged in sequence along the flow direction of the seed potatoes; a collating structure is arranged correspondingly below each grading area; a driving mechanism, drivingly connected to the first bottom plate; a lifting mechanism, 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 connected to the bottom of the debris removal barrel to close the bottom of the debris removal barrel, and the driving mechanism drives the first bottom plate to rotate; when in the second position, the first bottom plate is separated from the debris removal barrel to form a feeding channel for the seed potatoes to pass through.

[0005] The present invention can regulate the on and off of the impurity removal cylinder and the sorting device by regulating the lifting and lowering of the first bottom plate through the lifting mechanism, and the impurity removal and sorting are set as one, and the loading and unloading are also integrated, which reduces the processing procedures, improves the processing efficiency, and ensures the continuity of the equipment. Specifically, after the impurity removal is completed, the lifting mechanism drives the first bottom plate to move downward, and forms a material discharge channel between the impurity removal cylinder and the impurity removal cylinder, so that the seed potatoes directly enter the sorting device, and the material discharge of the impurity removal cylinder and the material loading of the sorting device are integrated, the seed selection is more convenient and fast, and the intermediate transportation link is omitted, the processing efficiency is significantly improved, and the continuity of production is ensured. 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 material discharge. At the same time, by arranging the cleaning column on the first bottom plate and using the driving mechanism to drive the first bottom plate to rotate, the cleaning column 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 be better detached. After sorting, the seed potatoes are arranged by the arrangement structure, which can avoid the disorder of the seed potato output, which is conducive to improving the accuracy and efficiency of the subsequent processing links.

[0033] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can regulate the on and off of the impurity removal barrel and the sorting device by regulating the lifting of the first bottom plate through the lifting mechanism, and the impurity removal and sorting are integrated, and the loading and unloading are also integrated, which reduces the processing steps, improves the processing efficiency, and ensures the continuity of the equipment. That is: after the impurity removal is completed, the lifting mechanism drives the first bottom plate to move downward, and forms a material unloading channel between the impurity removal barrel and the impurity removal barrel, so that the seed potatoes directly enter the sorting device. The unloading of the impurity removal barrel and the loading of the sorting device are integrated, which makes the seed selection more convenient and faster, eliminates the intermediate transportation link, significantly improves the processing efficiency, and ensures the continuity of production. At the same time, the gap between the impurity removal barrel and the first bottom plate can be flexibly adjusted according to the size of the seed potatoes to ensure smooth unloading.

[0034] 2. By arranging the cleaning column on the first bottom plate and using the driving mechanism to drive the first bottom plate to rotate, the cleaning column cleans the surface of the seed potatoes in the impurity removal cylinder and can continuously clean the surface of the seed potatoes, so that impurities such as dirt on the surface of the seed potatoes can be better removed. At the same time, the impurity removal cylinder rotates synchronously with the first bottom plate to further enhance the rolling and friction of the seed potatoes, so that the impurities of the seed potatoes are removed more thoroughly, and the impurity removal effect is further improved.

[0035] 3. By setting a second bottom plate under the first bottom plate, when the first bottom plate is docked with the debris removal barrel, the second bottom plate can be docked with the upper box body, thereby forming a debris removal channel on the periphery of the debris removal barrel, so that the soil and debris in the debris removal barrel can be discharged outward through the periphery of the debris removal barrel, thereby improving the output effect of soil and debris and greatly improving the debris removal efficiency. At the same time, by setting 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, it can not only ensure the sealing of the debris removal channel, but also can vibrate the first bottom plate through the elasticity of the spring when unloading after the debris removal is completed, so as to dredge the first row of debris holes. At the same time, when running in conjunction 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 impurities in the first row of debris holes, and also assisting the rapid fall of the seed potatoes to avoid accumulation.

[0036] 4. A negative pressure adsorption channel is formed by setting a first cavity in the column and connecting it to the exhaust fan. During the impurity removal process, the impurity removal channel on the outer periphery of the impurity removal cylinder cooperates with the first cavity (the impurities can not only be discharged from the outer periphery of the impurity removal cylinder, but also be discharged after entering the first cavity), further improving the output effect of soil and impurities, ensuring that the surface of the seed potato is thoroughly cleaned.

[0037] 5. By adding a second cavity in the column and inputting controllable airflow into the second cavity through a hair dryer, the airflow can be ejected through the 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 to 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 impurity removal is completed, realizing automatic transportation, reducing mechanical damage and improving processing efficiency.

[0038] 6. The present invention can arrange the seed potatoes in an orderly manner and evenly space them after sorting through the arrangement of the arranging structure, which effectively solves the problem of messy material output from traditional equipment, not only ensuring the continuity of the production process, but also providing an ideal material distribution state for subsequent visual inspection, seed cutting and other processes, significantly improving the accuracy and efficiency of subsequent processing links. The equipment integrates impurity removal, cleaning, sorting and arranging into the same device, making the entire seed potato selection process smoother and more efficient.

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Example 1

[0051] like Figure 1 to Figure 6 As shown, an embodiment of the present invention provides a potato seed potato selection device, including a chassis 1, a debris removal device 2, a driving mechanism 3, a lifting mechanism 4 and a sorting device 5.

[0052] The chassis 1 includes an upper case 1a and a lower case 1b disposed below the upper case 1a and connected thereto.

[0053] A debris removal barrel 11 and a first bottom plate 12 are arranged in the chassis 1 .

[0054] The impurity removal barrel 11 is rotatably arranged in the upper box body 1a. The top and bottom of the impurity removal barrel 11 are both open to form a feed end and a discharge end. The top feed end is connected to the feed port 11a arranged on the top of the impurity removal barrel 11. The first bottom plate 12 is movably arranged at the bottom discharge end of the impurity removal barrel 11. The driving mechanism 3 is drivingly connected to the first bottom plate 12, which can drive the first bottom plate 12 to rotate. The lifting mechanism 4 is transmission-connected to the first bottom plate 12, which can drive the first bottom plate 12 to perform 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 impurity removal barrel 11 under the drive of the lifting mechanism 4. When the first bottom plate 12 approaches the impurity removal barrel 11 and docks with it, it is connected to the impurity removal barrel 11 through the connecting piece 6, and the discharge end at the bottom of the impurity removal barrel 11 is closed. When it is away from the impurity removal barrel 11, the closure of the bottom of the impurity removal barrel 11 is released.

[0055] The impurity removal device 2 includes a cleaning column 21 arranged on the first bottom plate 12 for cleaning dirt and impurities on the surface of the seed potatoes and an output mechanism for outputting dirt and other impurities.

[0056] The sorting device 5 is arranged in the lower box 1b and outside the first bottom plate 12, and is used to receive the cleaned seed potatoes and perform grading operations on the seed potatoes. 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. The grading specifications of the grading areas are arranged from small to large from the feeding end of the seed potatoes to the other end. A corresponding alignment structure 52 is arranged under each grading area.

[0057] 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 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, driving the driving mechanism 3 and the first bottom plate 12 to rise or fall. When in use, when the lifting mechanism 4 drives the first bottom plate 12 to move upward, the first bottom plate 12 and the impurity removal barrel 11 can be docked. After the docking is completed, the seed potatoes are put into the impurity removal barrel 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 barrel 11 rotates synchronously with the first bottom plate 12 under the action of the connecting member 6, so that the cleaning column 21 arranged on the first bottom plate 12 cleans the surface of the seed potatoes in the impurity removal barrel 11, so that the soil and other impurities on the surface of the seed potatoes fall off, and the cleaned soil and other impurities are discharged through the output mechanism. After the impurities are removed, the lifting mechanism 4 drives the first bottom plate 12 to move downward, so that the first bottom plate 12 is separated from the impurities removal barrel 11, thereby forming a gap between the impurities removal barrel 11 and the first bottom plate 12, and the gap forms a feeding channel for the seed potatoes to enter the sorting device 5. The sorting device 5 receives the seed potatoes discharged from the feeding channel and performs a grading operation on the seed potatoes. By rotating the cleaning column 21 with the first bottom plate 12, under the action of the cleaning column 21, the soil and other impurities on the surface of the seed potatoes can be better removed. After the impurities are removed, by moving the first bottom plate 12 downward, the seed potatoes can be introduced into the sorting device 5, making the unloading of the impurities removal barrel 11 and the feeding of the sorting device 5 more convenient and faster, reducing the processing steps, improving the processing efficiency, and ensuring the continuity of the equipment. At the same time, the gap between the impurities removal barrel 11 and the first bottom plate 12 is adjustable, so that the seed potatoes can be discharged smoothly, reducing the risk of blockage during unloading. The seed potatoes entering the sorting device 5 are first graded by the screening structure 51 and then arranged in order by the arranging structure 52, so as to avoid disorder when the seed potatoes are discharged, facilitate subsequent processing operations, and improve the seed selection accuracy. The equipment integrates the four core functions of impurity removal, cleaning, sorting, and arranging into one device, making seed potato processing more convenient and efficient.

[0058] In one embodiment, the feed port of the upper box body 1a can also be connected to a filter box, in which a filter net is arranged. Before the seed potatoes are put into the impurity removal barrel 11, they are firstly filtered through the filter net to filter out the impurities in the seed potatoes and remove the seed potatoes that are too small.

[0059] In one embodiment, the output mechanism includes an exhaust fan connected to the interior of the debris removal barrel 11, and the soil and debris in the debris removal barrel 11 are extracted by the exhaust fan.

[0060] Example 2

[0061] The embodiment of the present invention provides a potato seed potato selection device. Based on the embodiment 1, in this embodiment, a second bottom plate 13 is further provided in the chassis 1.

[0062] The second bottom plate 13 is disposed 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 .

[0063] The bottom of the upper box body 1a extends into the lower box body 1b, that is, the lower part of the upper box body 1a forms a first extension part 12a on the upper part of the lower box body 1b. When the first bottom plate 12 is docked with the impurity removal barrel 11, the second bottom plate 13 is docked with the bottom of the first extension part 12a, so that the upper box body 1a is also formed into a closed space. Specifically, the size of the first bottom plate 12 is compatible with the impurity removal barrel 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 of the upper box body 1a. The size of the second bottom plate 13 is larger than the first bottom plate 12, the size of the second bottom plate 13 is greater than or equal to the size of the upper box body 1a, and the inner side of the second bottom plate 13 has a groove body 130. When the first bottom plate 12 is docked with the impurity removal barrel 11 and the second bottom plate 13 is docked with the upper box body 1a, the groove body 130 can be connected with the gap between the outer wall of the impurity removal barrel 11 and the inner wall of the upper box body 1a, thereby forming an interconnected impurity removal channel outside the impurity removal barrel 11.

[0064] Furthermore, a plurality of first debris row holes 121 are circumferentially distributed on the first bottom plate 12 and the debris removal barrel 11 , so that the interior of the debris removal barrel 11 is connected to the debris removal channel through the plurality of first debris row holes 121 .

[0065] In this embodiment, the impurity removal device 2 includes a plurality of flexible cleaning columns 21 and a soil and debris output mechanism.

[0066] The cleaning column 21 is fixed on the first bottom plate 12 and can clean the dirt and debris on the surface of the seed potatoes.

[0067] The output mechanism includes an exhaust fan, an exhaust pipe 22 and a telescopic tube 23. The input end of the exhaust fan is connected to the exhaust pipe 22, the exhaust pipe 22 is connected to one end of the telescopic tube 23, and the other end of the telescopic tube 23 passes through the second bottom plate 13 and is connected to the trough body 130, so that when the second bottom plate 13 is docked with the upper box body 1a, under the action of the exhaust fan, the soil and debris in the debris removal barrel 11 enter the exhaust channel through the first debris removal holes 121, and then enter the exhaust pipe 22 after entering the telescopic tube 23, and finally collected by a collection device connected to the output end of the exhaust fan. In this embodiment, the soil and debris in the debris removal barrel 11 can be output outward through the outer circumference of the debris removal barrel 11, which is conducive to improving the output effect of the soil and debris and improving the debris removal efficiency.

[0068] In one embodiment, a baffle 131 is provided on the upper surface of the second bottom plate 13, a movable plate 132 is movably provided 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 opened in the middle of the movable plate 132, and a first spring 133 is provided between the bottom of the movable plate 132 outside the through hole 1321 and the second bottom plate 13.

[0069] Optionally, a sealing ring 134 is disposed on the upper surface of the movable plate 132 .

[0070] When in use, when the second bottom plate 13 moves upward under the drive of the lifting mechanism 4, the sealing ring 134 above the second bottom plate 13 docks with the first extension portion 12a of the upper box body 1a, and the sealing ring 134 can fit tightly to the bottom of the upper box body 1a under the action of the first spring 133, so that the impurity removal channel forms a closed space, further improving the impurity removal effect. At the same time, when the second bottom plate 13 moves downward under the drive of 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, so that the sealing ring 134 can fit with the lower surface of the first bottom plate 12, so that the first spring 133 can produce a certain shaking on the first bottom plate 12, so as to dredge the first impurity removal hole 121 and reduce blockage. Moreover, when the impurity removal is completed, when the material is discharged by vibration, the vibration effect can be improved by cooperating with the first spring 133.

[0071] In one embodiment, a telescopic plate 135 is further provided on the side of the first spring 133 away from the baffle 131, and the telescopic plate 135 can be extended or shortened with the movement of the movable plate 132. By providing the telescopic plate 135, the supporting effect of the movable plate 132 can be improved. Exemplarily, the telescopic plate 135 can adopt a 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 slidably cooperates with the fixed plate, and the bottom of the telescopic plate is connected to the inner bottom surface of the fixed plate through the second spring, and the second spring cooperates with the first spring 133. When the movable plate 132 is docked with 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 restoring force of the first spring 133 and the second spring can better push the movable plate 132 to fit the lower surface of the first bottom plate 12.

[0072] During use, when the lifting mechanism 4 drives the bottom plate to move up, the first bottom plate 12 and the impurity removal barrel 11 can be docked. After the docking is completed, the seed potatoes are put into the impurity removal barrel 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 barrel 11 rotates synchronously with the first bottom plate 12 under the action of the connecting piece 6, so that the cleaning column 21 arranged on the first bottom plate 12 cleans the surface of the seed potatoes in the impurity removal barrel 11, so that the dirt and other impurities on the surface of the seed potatoes fall off. The cleaned dirt and other impurities enter the impurity removal channel through the first impurity removal holes 121 under the action of the exhaust fan, and are discharged to the designated position through the telescopic tube 23 and the impurity removal pipe 22 in sequence. After the impurities are removed, 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, so that 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, and the 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.

[0073] 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, which 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 and lowering movements. 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 mechanically sealed therewith. The lifting mechanism 4 is installed at the bottom of the lower box 1b, and its movable end is connected to the driving motor.

[0074] As an implementation scenario, refer to the attached Figure 1 and Figure 2 As shown, a limiting rod 14 is also provided in the chassis 1, and the limiting rod 14 is connected to the top inner wall of the lower box body 1b. The second bottom plate 13 extends outward with a second extension portion 13a, and the limiting rod 14 is provided above the second extension portion 13a, and its position corresponds to the second extension portion 13a. Through the setting of the limiting rod 14, when in use, when the lifting mechanism 4 drives the driving mechanism 3 to move upward to make the first bottom plate 12 and the impurity removal barrel 11 dock, 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 barrel 11 rotates synchronously with the first bottom plate 12 under the action of the connecting member 6, so that the cleaning column 21 provided on the first bottom plate 12 can clean the surface of the seed potatoes in the impurity removal barrel 11, so that the soil and other impurities on the surface of the seed potatoes fall off.

[0075] Optionally, the limiting rod 14 may adopt a cylinder and a rod body that are slidably matched, the cylinder body is fixed to the inner wall of the lower box body 1b, one end of the rod body is slidably arranged in the cylinder body, 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 under the drive of the lifting mechanism 4, the rod body can extend from the cylinder body, and the limiting rod 14 is extended as a whole. When the second bottom plate 13 rises and docks with the upper box body 1a, the rod body is inserted into the cylinder body, and the limiting rod is shortened as a whole. Of course, the limiting rod 14 can also adopt a rod body with an integrated structure that is directly fixed above the second extension part 13a.

Since the debris removal channel is connected to the first cavity 2111, when the exhaust fan is activated, the debris can not only be discharged from the outer periphery of the debris removal barrel 11, but also can be discharged after entering the first cavity inside the column 211. When the cleaning layer 212 cleans the surface of the seed potato, some dust and debris can be promptly removed through the third row of debris holes 2113, that is, the dust and debris enter the first cavity 2111 through the third row of debris holes 2113, and then enter the trough body 130 through the second row of debris holes 2112, and then enter the telescopic tube 23.

When in use, by starting the hair dryer, the hair dryer inputs airflow to the second cavity 2114 through the air outlet pipe 24, and the airflow is blown out through the blowing holes 2115. On the one hand, impurities attached to the surface of the seed potatoes can be blown off, and the impurity removal effect can be further improved by cooperating with the effect of the exhaust fan. On the other hand, by adjusting the wind force of the hair dryer, after the impurity removal of the seed potatoes is completed, the seed potatoes can be blown to the sorting device 5 to complete the unloading and loading of the seed potatoes.

[0083] Optionally, a movable baffle 25 is provided in the air blowing hole 2115, one end of the movable baffle 25 is connected to 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, and the movable baffle 25 is located in the air blowing hole 2115 and adapted thereto. When the third spring 28 is in a natural state, the movable baffle 25 is located at the small end of the air blowing hole 2115 and closes it. When the hair dryer is activated, the movable baffle 25 will move to the large end outside the air blowing hole 2115 under the action of the air flow, so that the outside of the second cavity 2114 is connected. When the present embodiment is in use, the blowing hole 2115 can be enlarged. When the wind force is increased, the seed potatoes can be better blown to the sorting device 5. The movable baffle 25 can be set to prevent the seed potatoes from entering the second cavity 2114 from the blowing hole 2115 when the hair dryer is not activated during the impurity removal process.

[0084] In order to match the setting of the movable baffle 25, the depth of the 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 arranged on the outer wall of the cylinder 211, the sponge layer or the brush is arranged outside the rubber layer as a contact layer in contact with the seed potatoes, the 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.

[0086] Optionally, a flexible arc-shaped protrusion 213 is further provided on the upper end of the column 211 .

[0087] As an implementation scenario, in this scenario, a vertical plate 15 is arranged below the second bottom plate 13. When the second bottom plate 13 moves downward away from the impurity removing barrel 11, its bottom contacts the vertical plate 15, so that the second bottom plate 13, the vertical plate 15 and the bottom wall of the lower box body 1b are surrounded by an equipment installation room in the lower box body 1b, and the outer side of the vertical plate 15 is a sorting room, and the sorting device 5 is arranged in the sorting room.

[0088] Optionally, the telescopic tube 23 is arranged in the equipment installation room, one end of the exhaust pipe 22 is connected to the telescopic tube 23, and the other end extends to the outside of the equipment installation room to be connected to the exhaust fan.

[0089] Optionally, the driving mechanism 3 and the lifting mechanism 4 are installed in the equipment installation room.

[0090] Optionally, the equipment installation room is further provided with an air inlet cavity 29, on which a joint is provided, the position of the joint corresponds to the position of the air outlet pipe 24, and the air outlet pipe 24 can be movably sealed and plugged with the joint, that is, one end of the air outlet pipe 24 passes through the first bottom plate 12 and connects with the bottom of the column 211, and the other end passes through the second bottom plate 13 and extends to the bottom of the second bottom plate 13, and the air outlet pipe 24 can be rotatably matched with the second bottom plate 13 through a sealing bearing.

[0093] Example 5

[0094] The embodiment of the present invention provides a potato seed potato selection device. On the basis of embodiment 4, a material guide component 7 is further provided on the upper part of the debris removal drum 11.

[0095] Two feed ports 11a are respectively arranged on both sides of the top of the upper box body 1a, and a material guiding assembly 7 is correspondingly arranged in the impurity removal cylinder 11 below the feed ports 11a.

[0096] The material guide assembly 7 includes a material guide plate 71 and a fourth spring 72. One end of the material guide plate 71 is hinged to the inner wall of the impurity removal barrel 11, and the fourth spring 72 is arranged between the middle position of the bottom of the material guide plate 71 and the inner wall of the impurity removal barrel 11. One end of the fourth spring 72 is connected to the inner wall of the impurity removal barrel 11, and the other end is connected to the material guide plate 71. By setting the material guide plate 71, the seed potatoes put in can be buffered to prevent the seed potatoes from being damaged due to too high a drop during feeding.

[0097] Optionally, the cleaning column 21 is arranged at the middle of the impurity removal barrel 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 seed potatoes are fed, they are first buffered by the guide plate 71, and then fall on the arc-shaped protrusion 213 for buffering again, which can further improve the buffering effect on the one hand, and on the other hand, the seed potatoes will slide from the outside after passing through the arc-shaped protrusion 213, and thus enter between the two cleaning columns 21, so that the cleaning layer 212 can clean the surface of the seed potatoes and improve the cleaning effect.

[0098] In one embodiment, the material guide assembly 7 further comprises an air bag 73. The air bag 73 is arranged between the material guide plate 71 and the inner wall of the impurity removal cylinder 11. By inflating or deflating the air bag 73, the inclination of the material guide plate 71 can be adjusted for easy use.

[0099] Example 6

[0100] The embodiment of the present invention provides a potato seed selection device. Based on any of the above embodiments, in this embodiment, a notch 111 is provided at the bottom of the impurity removal barrel 11, and the connecting member 6 includes a first magnet 61 and a second magnet 62.

[0101] Specifically, the first magnet 61 is fixed on the first bottom plate 12, and its position corresponds to the slot 111. The first magnet 61 adopts a columnar structure, the slot 111 is adapted to the first magnet, and the first magnet 61 can be movably inserted in the slot 111. The second magnet 62 is movably arranged in the slot 111 through a connecting rope 63, and the second magnet 62 is slidably matched with the inner wall of the slot 111, and the length of the connecting rope 63 is less than the depth of the slot 111.

[0102] Optionally, the lower end of the impurity removing barrel 11 is thickened, and the notch 111 is opened in the thickened portion.

[0103] When in use, when the first bottom plate 12 moves upward under the drive of the lifting mechanism 4, the first magnet 61 on the first bottom plate 12 is inserted into the notch 111, thereby fixing the relative position of the first bottom plate 12 and the impurity removal barrel 11, so that the impurity removal barrel 11 can be driven to rotate when the driving shaft of the driving mechanism 3 rotates. At the same time, by setting the connected column as a magnet and setting a matching second magnet 62 in the notch 111, on the one hand, the stability of the connection between the impurity removal barrel 11 and the first bottom plate 12 can be strengthened, and on the other hand, the first bottom plate 12 and the second bottom plate 13 can be easily reset, that is: when the first bottom 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 bottom plate 12 to rotate, so that the first magnet 61 is located below the notch 111 so that it can be smoothly inserted into the notch 111. Of course, the first base plate 12 can also be reset by the driving mechanism 3, that is, the initial position of the first base plate 12 is set so that the first magnet 61 is located 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.

[0104] As an implementation scenario, in this scenario, the impurity removal barrel 11 and the first bottom plate 12 are both circular structures, and two or four material discharge channels can be formed below the upper box body 1a.

For example, a sorting chamber is provided on the left and right sides of the bottom of the upper box body 1a, and a material blocking structure is provided on the front and back sides of the upper box body 1a. When the impurity removal barrel 11 discharges materials, the seed potatoes can only enter the sorting devices 5 on both sides from the material discharge channels on the left and right sides. Correspondingly, when the blowing holes 2115 are provided, the blowing direction is toward the material discharge channels on the left and right sides. Of course, a sorting chamber can also be provided on the front, back, left and right sides of the bottom of the upper box body 1a.

[0105] Example 7

[0106] An embodiment of the present invention application provides a potato seed potato selection device. Based on any of the above embodiments, in this embodiment, the sorting device 5 includes a screening structure 51 and an array structure 52. The screening structure 51 has multiple grading areas of different specifications. The grading specifications of the grading areas are arranged from small to large from the feed end of the seed potato to the other end. A group of array structures 52 is arranged under each grading area.

[0107] In this embodiment, the screening structure 51 includes a screen plate 511, and the screen plate 511 has multiple grading areas. Exemplarily, the screen plate 511 includes a first grading area 51a, a second grading area 51b, and a third grading area 51c, and the screen holes of the screen plate 511 are arranged from small to large from one side of the feeding channel to the other side. The third grading area 51c has a discharge area on the side away from the second grading area 51b, and a group of column structures 52 are respectively arranged below the three grading areas.

[0108] Optionally, a stop bar 5111 is provided between adjacent grading areas, and one side of the stop bar 5111 is provided in an inwardly concave arc, that is, a stop bar 5111 is 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, respectively. Through the setting of the stop bar, the seed potatoes can be blocked to a certain extent during grading, thereby increasing the time that the seed potatoes stay in the grading area and improving the grading effect.

[0109] Optionally, the potato seed selection equipment further includes a vibration device 8, which can be installed on the vertical plate 15, and is used to vibrate the screening structure 51 or the screening structure 51 and the second bottom plate 13. Vibrating the second bottom plate 13 by the vibration device 8, in conjunction with the air holes 2115, can further ensure the smoothness of seed potato feeding. Vibrating the screening structure 51 by the vibration device 8 can improve the grading efficiency. When the vibration device 8 vibrates the second bottom plate 13, the vibration 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 row of miscellaneous holes 121. The vibration device 8 is a prior art, such as using a vibration motor, and its implementation process and working principle are not repeated here.

[0110] When in use, after the seed potatoes are cleaned in the cleaning cylinder 11, they first enter the first grading area 51a from the discharge channel. Under the action of the vibration device 8, the seed potatoes with smaller specifications fall into a group of aligned structures 52 below through the first grading area 51a, the seed potatoes with medium specifications fall into a group of aligned structures 52 below through the second grading area 51b, and the seed potatoes with larger specifications fall into a group of aligned structures 52 below through the third grading area 51c. The seed potatoes with extra large specifications are discharged from the discharge area. In one embodiment, the seed potatoes discharged from the discharge area can also be set up by a group of aligned structures so that they fall into the aligned structures 52.

[0111] Example 8

[0112] The present invention provides a potato seed selection device, such as Figure 7 As shown, in this embodiment, the sorting device 5 includes a screening structure 51 and an arranging structure 52. The screening structure 51 has a plurality of grading areas of different specifications, and a group of arranging structures 52 is correspondingly arranged under each grading area.

[0113] In this embodiment, the screening structure 51 includes a first inclined plate 512 and a plurality of second inclined plates 513. The inclined 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 whole array structure 52. The plurality of second inclined plates 513 are arranged at intervals on one side of the first inclined plate 512, and their inclined low ends are respectively connected to the corresponding hopper tops. The second inclined plate 513 is hinged to the hopper top and / or the inclined high ends of the second inclined plate 513 are respectively telescopically provided with round rods 514. By rotatably setting the second inclined plate 513 or telescopically setting the round rods 514 at the upper end, the gap between adjacent inclined plates can be adjusted, so that, when in use, it can be adaptively adjusted according to the classification requirements.

[0114] Optionally, the upper end of the second inclined plate 513 is rounded.

[0115] Optionally, the upper end of the second inclined plate 513 is in a downward step structure from one end to the other end of the first inclined plate 512 .

[0116] As an implementation scenario, in this scenario, the second inclined plate 513 is rotatably connected to the top of the hopper via a rotating shaft, and when the second inclined plate 513 is adjusted to a desired inclination angle, it can be fixed by fasteners.

[0117] As an implementation scenario, in this scenario, the second inclined plate 513 has a retractable round rod 514 at the inclined high end. The round rod 514 can be retracted into the second inclined plate 513 or extended out of the second inclined plate 513, so that the gap between adjacent inclined plates can be adjusted.

[0118] Specifically, a plurality of second inclined plates 513 spaced apart outside the first inclined plate 512 form a first grading area 51a, a second grading area 51b, a third grading area 51c and a discharge area 51d above the entire structure 52. The sizes of the first, second and third grading areas are adjusted by adjusting the length of the round rods 514. Exemplarily, the round rods close to the first inclined plate 512 are fully extended, thereby forming a smaller material distribution opening with the first inclined plate 512; the round rods in the middle are partially extended, thereby forming a medium-shaped material distribution opening with the adjacent second inclined plate; the round rods far from the first inclined plate are not extended, thereby forming a larger material distribution opening with the adjacent inclined plate.

[0119] Optionally, the round rod 514 is connected to the second inclined plate 513 through an insert plate. Specifically, a slot is provided at the upper end of the second inclined plate 513, and the insert plate is inserted into the slot. Optionally, the insert plate is made of rubber material and is squeezed and connected to the slot. When in use, the insert plate can be pulled out of the slot or inserted into the slot by applying a pulling force or a pushing force to the insert plate.

[0120] When in use, the door of the sorting chamber is first opened, and then the inclination of the second inclined plate 513 and / or the extension length of the round rod 514 are adjusted. After the seed potatoes are cleaned in the cleaning barrel 11, the seed potatoes first enter the first grading area 51a from the feeding channel, and the seed potatoes with smaller specifications fall into a group of alignment structures 52 below through the first grading area 51a, and the remaining seed potatoes continue to roll down due to the setting of the step structure and the action of the vibration device 8, so that the seed potatoes with medium specifications fall into the group of alignment structures 52 below through the second grading area 51b, and the seed potatoes with larger specifications fall into the group of alignment structures 52 below through the third grading area 51c, and the seed potatoes with extra large specifications are discharged from the discharge area 51d. In one embodiment, a group of alignment structures 52 is also added below the discharge area 51d, so that the seed potatoes discharged from the discharge area 51d also fall into the alignment structure for alignment.

[0121] The screening structure 51 provided in this embodiment can adjust each grading area according to different grading requirements when used, compared with the fixed sieve plate in Example 7, and is more flexible and convenient to use, and has a wide range of applications. It should be noted that in the accompanying drawings, the setting position of the inclined plate, its inclination angle and the spacing distance between adjacent inclined plates are all schematic, and are only used to express the idea of ​​the technical solution, and do not involve the limitation of the specific position in the actual embodiment.

[0122] Example 9

[0123] The present invention provides a potato seed selection device, referring to Figure 1 to Figure 6 As shown, in this embodiment, the sorting device 5 includes a screening structure 51 and an arranging structure 52. The screening structure 51 has a plurality of grading areas of different specifications, and a group of arranging structures 52 is correspondingly arranged under each grading area.

[0124] Furthermore, the entire structure 52 includes a hopper 521, a material roller 522 and a motor.

[0125] The hopper 521 includes a connected receiving portion 521a and a discharging portion 521b. The upper end of the receiving portion 521a is open and docked with the corresponding grading area to receive the seed potatoes dropped from the grading area. The discharging portion 521b has a circular structure in cross section. The material roller 522 is adapted to the structure of the discharging portion 521b and is installed in the discharging portion 521b, and a discharge port 5211 is provided at the bottom end of the discharging portion 521b.

[0126] The size of the material roller 522 matches the size of the material discharge portion 521b, and the outer wall thereof is provided with a material groove 5221. The motor is drivingly connected to the material roller 522, and the motor can drive the material roller 522 to rotate slowly.

[0127] During use, when the material trough 5221 is located below the material receiving part 521a and connected thereto, the seed potatoes in the material receiving part 521a fall into the material trough 5221 , and the material roller 522 continues to rotate driven by the motor. When the material trough 5221 moves to the material outlet 5211 , the seed potatoes are discharged from the material outlet 5211 .

[0128] As an implementation scenario, in this scenario, the material trough 5221 is a longer material trough, that is, the material trough 5221 is opened along the length direction of the material roller 522, and its length is basically equal to the length of the material roller.
