Description

Technical Field

[0001] The invention relates to the technical field of potato stock screening, in particular to potato stock grading and screening equipment with a shunt structure. Background Art

[0002] The original potato is an annual herbaceous plant of the genus Solanum in the Solanaceae family. The aboveground stem is diamond-shaped and hairy. Genetically modified potatoes: smooth surface. The leaves of the original potato are simple when they are first born, and gradually grow into an odd number of unequal pinnate compound leaves, which are ovate to oblong in shape; the umbels grow at the top, and the flowers are white or blue-purple; the fruits are berries; the tubers are oblate or spherical, glabrous or sparsely hairy; the potato skin is white, light red or purple; the potato flesh is white, light yellow, yellow and other colors. The flowering period is summer. The original potato is named because it resembles a bell.

[0003] The potato stock originated in the mountains of tropical America. It was introduced to India in the 16th century and then to China. It is now widely planted in temperate regions around the world. The potato stock prefers cool and dry climates and has strong adaptability. It prefers loose and fertile sandy soil. It has a short growth cycle and high yield. Because seed propagation will lead to trait separation, the most commonly used method of propagation of potato stock is asexual tuber propagation.

[0004] At present, the existing potato seed grading and screening equipment mostly uses screens for screening potato seeds. The sides of the screens are easily worn and broken due to the impact of the falling potato seeds for a long time, which affects the screening process of the screening equipment. Summary of the invention

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a potato seed grading and screening device with a diversion structure, comprising a base, the base is used to stably place the grading and screening components, and a lifting frame is fixedly installed on one side of the outer surface of the base;

[0006] A guiding component, wherein the guiding component is used for guiding potato original seed screening materials;

[0007] A receiving assembly, the receiving assembly is used for vibratory screening of potato seed stock, a transmission assembly is fixedly mounted on the outer surface of the receiving assembly, a vibrator is fixedly and rotatably mounted on the surface of the transmission assembly, and a guide tube is fixedly mounted on the surface of the receiving assembly away from the transmission assembly;

[0008] A screening component, wherein the screening component is used for screening potato stock protection;

[0009] The receiving components are provided with two groups, and the two groups of receiving components are respectively fixedly mounted on the top of the base and the lifting frame, the screening component is fixedly mounted in the middle of the opposite surface of the receiving components, and the guiding component is fixedly mounted inside the receiving components close to the lifting frame side, and the guiding component is adapted to the receiving components; the staff starts the motor so that the output end of the motor drives the vibrator to transmit the vibration to the surface of the receiving components, so that the receiving components vibrate. At this time, when the staff screens the potato seeds, they pour the potato seeds along the guiding components into the receiving components on the lifting frame side, so that the potato seeds fall to the top of the screening component. Since the receiving components are deformed due to the influence of gravity of the falling potato seeds, the potato seeds smaller than the sieve holes on the screening component fall into the receiving components below the screening component, and as the receiving components continue to vibrate, the fallen potato seeds are transported along the guide pipe to the receiving components in the lower layer for secondary screening.

[0010] The transmission assembly includes a support frame, a fixed block is fixedly installed on the top of the support frame, a mounting plate is fixedly installed on the top of the fixed block, a pad is rotatably installed on the surface of the mounting plate through a hinge rod, a shock-absorbing spring is fixedly installed on the opposite surface assembly of the pad and the mounting plate, a motor is fixedly installed on the top of the pad, and the output end of the motor is fixedly connected to the vibrator. The staff starts the motor so that the output end of the motor drives the vibrator to rotate, so that the receiving assembly is subjected to force and vibrates. When the vibrator is running, since the motor is installed on the outside of the extension frame through the support frame, the vibration of the receiving assembly will cause the motor to shake. At this time, the pad arranged below the motor rotates above the mounting plate with the vibration and squeezes the shock-absorbing spring, so that the shock-absorbing spring is forced to shrink and reduce the vibration frequency of the pad, thereby protecting the motor and preventing the motor from loosening due to long-term vibration.

[0011] Preferably, the receiving assembly includes a bottom plate, a baffle is fixedly installed at the top side of the bottom plate, side plates are fixedly installed on both sides of the outer surface of the baffle, fixing frames are fixedly installed on the outer surfaces of the side plates, the side plates are fixedly installed on both sides of the top of the bottom plate through the fixing frames, and an inclined plate is fixedly installed on the top of the side plates. The side plates fixedly support the screening assembly, and the potato seed sieved from the screening assembly falls above the bottom plate. As the vibrator vibrates, the sieved potato seed is guided along the guide pipe to the screening assembly at the lower layer for secondary screening, so as to facilitate the grading and screening of the potato seed.

[0012] Preferably, a connecting plate is fixedly installed on the outer surface of the fixing frame, an extension frame is fixedly installed on the outer surface of the connecting plate, and the surface of the connecting plate away from the extension frame is fixedly connected to the guide tube, the supporting frame is fixedly installed on the outer surface of the extension frame, and the vibrator is adapted to the baffle.

[0013] Preferably, the guiding assembly includes a guide frame plate, connecting plates are fixedly installed on both sides of the outer surface of the guide frame plate, the connecting plates are fixedly installed at the top sides of the baffle, a rotating rod is rotatably installed between the opposite surfaces of the connecting plates, a buffer assembly is sleeved on the outer surface of the rotating rod, and three groups of the buffer assemblies are provided, all of which are adapted to knock with the baffle, and the buffer assemblies are rotatably adapted to the rotating rod. The staff dumps the potato seeds onto the top of the guide frame plate, which is set at an angle. At this time, the potato seeds slide downward along the inclination angle of the guide frame plate. At this time, the sliding potato seeds contact the buffer component and drive the buffer component to rotate downward on the surface of the rotating rod, so that the buffer component rotates to contact the inner wall of the baffle. The vibrator is set on the outside of the baffle. When the buffer component guides the potato seeds, multiple groups of buffer components are squeezed by the potato seeds and vibrated by the vibrator in swinging states of different frequencies. Compared with the traditional material guiding method, the potato seeds are diverted and guided, which speeds up the fluidity of the potato seeds when they slide down and avoids blockage when the potato seeds are guided.

[0014] Preferably, the buffer assembly includes a sleeve, which is sleeved on the outer surface of the rotating rod, and the sleeve is rotatably installed on the outer surface of the sleeve. A covering sheet is fixedly installed on the outer surface of the sleeve, an extension pad is fixedly installed on the surface of the covering sheet, and an extrusion cavity is arranged inside the extension pad.

[0015] Preferably, a knocking plate is fixedly installed at the bottom of the extension pad, and two knocking plates are provided. The surfaces of the two knocking plates are provided with mounting grooves, and knocking balls are fixedly installed inside the mounting grooves, and the knocking balls are squeezed and adapted to the extension pad. When the potato stock slides down, it impacts the extension pad, so that the extension pad is forced to drive the sleeve to rotate downward on the surface of the rotating rod, so that the knocking plate and the inner wall of the baffle are abutted against each other and the vibration transmitted by the vibrator is transmitted. An extrusion cavity is provided in the extension pad to buffer the sliding potato stock, and at the same time, the extension pad is forced to be depressed downward to squeeze the extrusion cavity, so that the bottom of the extension pad collides with the knocking ball to limit the extension pad.

[0016] Preferably, the screening assembly includes a side plate, two of which are provided, and the two side plates are fixedly mounted on the surface of the side plate, and the surface of the side plate is respectively fixedly mounted with a top clamp and a tensioning support, and the tensioning support is fixedly mounted below the top clamp. Due to different potato seed screening standards, when only the potato seed size is screened, the staff pours the potato seed onto the top of the sub-screen, and the impact generated when the potato seed falls causes the sub-screen to deform. Since the sub-screen is made of a flexible mesh material and is deformed by the gravity of the potato seed falling, the potato seed bounces on the surface of the sub-screen after falling. The easily deformable elastic mesh can reduce the impact between the potato seed and the screen when it falls, and screen the irregular potato seed when the potato seed bounces, so as to protect the potato seed from damage on the surface of the potato seed, and then the smaller potato seed is vibrated and falls through the holes of the sub-screen to be screened out.

[0017] Preferably, a bent slot is provided between the top clamping plate and the opposite surface of the tensioning support, the bent slot is set as a U-shaped slot, a connection slot is fixedly installed on the surface of the bent slot close to the side plate, the connection slot is connected and adapted to the tensioning support, a bent hook is fixedly installed inside the bent slot, a sub-screen is fixedly installed on the surface of the bent hook, the sub-screen is set as a flexible grid material, and the sub-screen is set between the opposite surfaces of the side plates through the bent hook. The top clamping plate and the folding plate limit the bent slot, the bent slot is set as a U-shaped arc, when the sub-screen is deformed by force, the bent hook drives the bent slot to slide inside the top clamping plate and the folding plate, and the curved surface of the bent slot generates friction with the surface of the folding plate, so as to fix the sub-screen and buffer it from both sides when the sub-screen is subjected to force, so as to avoid the sub-screen from being broken due to friction on the side subjected to long-term force.

[0018] Preferably, the tensioning support frame includes an inclined frame plate, the inclined frame plate is fixedly connected to the side plate, a folding plate is fixedly installed on the top of the inclined frame plate, the folding plate is snap-fitted with the bent slot, and the upper surface of the folding plate is slidably fitted with the bent surface of the bent slot. When screening the size of the potato original seed and its surface smoothness, the staff pulls the bent slots on both sides so that the bent slots are snap-fitted with the card blocks through the snap-fitting slots. At this time, the bent slots are snap-fitted in the positioning cavity to stretch and position the sub-screen. Since there are three snap-fitting slots, the tightness of the sub-screen can be adjusted by snapping different snap-fitting slots with the tensioning support frame, thereby changing the elasticity of the sub-screen. When the sub-screen is in a tight state, the grid is not easy to deform, and irregular potatoes are difficult to be thrown out from between the grids, so that it is easy to adjust the tightness of the sub-screen according to different screening standards, thereby improving the utilization rate and screening effect of the screening equipment.

[0019] Preferably, a snap-fit ​​seat is fixedly installed on the surface of the inclined frame plate close to the bent slot, a positioning cavity is opened inside the snap-fit ​​seat, and a snap block and an extrusion sheet are fixedly installed on both sides of the outer surface of the positioning cavity, the snap block is snap-fitted with the snap-fit ​​slot, and the extrusion sheet is slidably fitted with the bent slot.

[0020] The present invention provides a potato seed grading and screening device with a diversion structure, which has the following beneficial effects:

[0021] 1. The potato seed grading and screening equipment with a diversion structure is configured such that a worker dumps the potato seeds onto the top of a guide frame plate, and the guide frame plate is tilted. At this time, the potato seeds slide downward along the tilt angle of the guide frame plate. At this time, the potato seeds sliding down contact with a buffer component and drive the buffer component to rotate downward on the surface of a rotating rod, so that the buffer component rotates to contact with the inner wall of the baffle plate. A vibrator is arranged on the outside of the baffle plate. When the buffer component guides the potato seeds, multiple groups of buffer components are squeezed by the potato seeds and vibrated by the vibrator in swinging states of different frequencies. Compared with the traditional material guiding method, the potato seeds are diverted and guided, which speeds up the fluidity of the potato seeds when they slide down, and avoids blockage when the potato seeds are guided.

[0022] 2. The potato seed grading and screening equipment with a diversion structure, when the potato seed slides down, impacts the extension pad, so that the extension pad is forced to drive the sleeve to rotate downward on the surface of the rotating rod, so that the knocking plate and the inner wall of the baffle are abutted against each other, and the vibration transmitted by the vibrator is transmitted. An extrusion cavity is provided in the extension pad to cushion the sliding potato seed. At the same time, the extension pad is forced to be depressed downward to squeeze the extrusion cavity, so that the bottom of the extension pad collides with the knocking ball to limit the extension pad.

[0023] 3. The potato seed grading and screening equipment with a diversion structure limits the bending slot by the top clamp and the folding plate. The bending slot is set to a U-shaped arc shape. When the sub-screen is deformed by force, the bending hook drives the bending slot to slide inside the top clamp and the folding plate. The curved surface of the bending slot generates friction with the surface of the folding plate, thereby fixing the sub-screen and buffering it from both sides when the sub-screen is subjected to force, thereby preventing the sub-screen from being broken due to friction on the side that is subjected to force for a long time.

[0024] 4. The potato seed grading and screening equipment with a diversion structure, due to different potato seed screening standards, only screens the potato seed size. The staff pours the potato seed onto the top of the sub-screen. The impact generated when the potato seed falls causes the sub-screen to deform. Since the sub-screen is made of a flexible mesh material and is deformed by the gravity of the falling potato seed, the potato seed bounces on the surface of the sub-screen after falling. The easily deformable elastic mesh can reduce the impact between the potato seed and the screen when it falls, and screens irregular potato seeds when the potato seed bounces, so as to protect the potato seed from damage on the surface of the potato seed. Then the smaller potato seeds are vibrated and fall through the holes of the sub-screen to be screened out.

[0025] 5. The potato seed grading and screening equipment with a diversion structure, when screening the potato seed size and surface smoothness, the staff pulls the bent slots on both sides so that the bent slots are engaged and adapted with the card blocks through the engaging slots. At this time, the bent slots are arranged in the positioning cavity to stretch and position the sub-screen. Since there are three engaging slots, the tightness of the sub-screen can be adjusted by engaging different engaging slots with the tensioning support frame, thereby changing the elasticity of the sub-screen. When the sub-screen is in a taut state, the grid is not easily deformed, and irregular potatoes are difficult to be thrown out from between the grids, so that the tightness of the sub-screen can be adjusted according to different screening standards, thereby improving the utilization rate and screening effect of the screening equipment.

[0041] A receiving component 6, the receiving component 6 is used for vibrating and screening potato seed stock, a transmission component 2 is fixedly mounted on the outer surface of the receiving component 6, a vibrator 8 is fixedly and rotatably mounted on the surface of the transmission component 2, and a guide tube 5 is fixedly mounted on the surface of the receiving component 6 away from the transmission component 2;

[0042] A screening component 4, wherein the screening component 4 is used for screening potato original seed protection;

[0043] The receiving assembly 6 is provided with two groups, and the two groups of receiving assemblies 6 are fixedly mounted on the top of the base 3 and the lifting frame 1 respectively, the screening assembly 4 is fixedly mounted in the middle of the opposite surface of the receiving assembly 6, and the guide assembly 7 is fixedly mounted inside the receiving assembly 6 on the side close to the lifting frame 1, and the guide assembly 7 is adapted to the receiving assembly 6; the staff starts the motor 21, so that the output end of the motor 21 drives the vibrator 8 to transmit the vibration to the surface of the receiving assembly 6, so that the receiving assembly 6 vibrates, and the work When screening potato seeds, the personnel pour the potato seeds along the guide assembly 7 into the receiving assembly 6 on one side of the lifting frame 1, so that the potato seeds fall to the top of the screening assembly 4. Since the receiving assembly 6 is deformed by the gravity of the falling potato seeds, the potato seeds smaller than the sieve holes on the screening assembly 4 fall into the receiving assembly 6 below the screening assembly 4, and as the receiving assembly 6 continues to vibrate, the fallen potato seeds are transported along the guide tube 5 to the receiving assembly 6 on the lower layer for secondary screening.

[0044] The transmission assembly 2 includes a support frame 26, a fixed block 25 is fixedly installed on the top of the support frame 26, a mounting plate 24 is fixedly installed on the top of the fixed block 25, a pad 23 is rotatably installed on the surface of the mounting plate 24 through a hinge rod, a damping spring 22 is fixedly installed on the opposite surface assembly of the pad 23 and the mounting plate 24, a motor 21 is fixedly installed on the top of the pad 23, and the output end of the motor 21 is fixedly connected to the vibrator 8. The staff starts the motor 21, so that the output end of the motor 21 drives the vibrator 8 to rotate, so that the receiving assembly 6 is forced to vibrate. When the vibrator 8 is running, since the motor 21 is installed on the outside of the extension frame 63 through the support frame 26, the vibration of the receiving assembly 6 will cause the motor 21 to shake. At this time, the pad 23 set below the motor 21 rotates above the mounting plate 24 with the vibration and squeezes the damping spring 22, so that the damping spring 22 is forced to shrink to reduce the vibration frequency of the pad 23, thereby protecting the motor 21 and preventing the motor 21 from loosening after long-term vibration.

[0045] The second embodiment is based on the first embodiment. Figures 5 to 7As shown, the receiving assembly 6 includes a bottom plate 64, a baffle 65 is fixedly installed at the top side of the bottom plate 64, side plates 66 are fixedly installed on both sides of the outer surface of the baffle 65, a fixing frame 62 is fixedly installed on the outer surface of the side plate 66, the side plate 66 is fixedly installed on both sides of the top of the bottom plate 64 through the fixing frame 62, and an inclined plate 61 is fixedly installed on the top of the side plate 66. The side plate 66 fixedly supports the screening assembly 4, and the potato seed sieved from the screening assembly 4 falls to the top of the bottom plate 64. As the vibrator 8 vibrates, the sieved potato seed is guided along the guide pipe 5 to the screening assembly 4 at the lower layer for secondary screening, so as to facilitate the grading and screening of the potato seed.

[0046] A connecting plate 67 is fixedly installed on the outer surface of the fixing frame 62, an extension frame 63 is fixedly installed on the outer surface of the connecting plate 67, and the surface of the connecting plate 67 away from the extension frame 63 is fixedly connected to the guide tube 5, the support frame 26 is fixedly installed on the outer surface of the extension frame 63, and the vibrator 8 is adapted to the baffle 65.

[0047] The guide assembly 7 includes a guide frame plate 71, and connecting plates 74 are fixedly installed on both sides of the outer surface of the guide frame plate 71. The connecting plates 74 are fixedly installed at the top sides of the baffle 65. A rotating rod 73 is rotatably installed between the opposite surfaces of the connecting plates 74. The outer surface of the rotating rod 73 is sleeved with a buffer assembly 72. The buffer assembly 72 is provided with three groups. The three groups of buffer assemblies 72 are all knocked and adapted to the baffle 65, and the buffer assembly 72 is rotationally adapted to the rotating rod 73. The staff dumps the potato seeds onto the top of the guide frame plate 71, and the guide frame plate 71 is set at an angle. At this time, the potato seeds slide downward along the inclination angle of the guide frame plate 71. At this time, the sliding potato seeds contact the buffer component 72 and drive the buffer component 72 to rotate downward on the surface of the rotating rod 73, so that the buffer component 72 rotates to contact the inner wall of the baffle 65. The vibrator 8 is set on the outside of the baffle 65. When the buffer component 72 guides the potato seeds, multiple groups of buffer components 72 are squeezed by the potato seeds and vibrated by the vibrator 8 in swinging states with different frequencies. Compared with the traditional material guiding method, the potato seeds are diverted and guided, which speeds up the fluidity of the potato seeds when they slide down, and avoids blockage when the potato seeds are guided.

[0048] The buffer assembly 72 includes a sleeve 721, which is sleeved on the outer surface of the rotating rod 73. The sleeve 721 is rotatably installed on the outer surface of the sleeve 721. A covering sheet 724 is fixedly installed on the outer surface of the sleeve 721. An extension pad 726 is fixedly installed on the surface of the covering sheet 724. An extrusion cavity 725 is arranged inside the extension pad 726.

[0049] A knocking plate 723 is fixedly installed at the bottom of the extension pad 726. There are two knocking plates 723. The surfaces of the two knocking plates 723 are provided with mounting grooves 722. The inside of the mounting grooves 722 is fixedly provided with knocking balls 727. The knocking balls 727 are pressed and adapted to the extension pad 726. When the potato stock slides down, it impacts the extension pad 726, so that the extension pad 726 is forced to drive the sleeve 721 to rotate downward on the surface of the rotating rod 73, so that the knocking plate 723 is against the inner wall of the baffle 65, and the vibration transmitted by the vibrator 8 is transmitted. An extrusion cavity 725 is provided in the extension pad 726 to buffer the potato stock sliding down. At the same time, the extension pad 726 is forced to be depressed downward to squeeze the extrusion cavity 725, so that the bottom of the extension pad 726 collides with the knocking ball 727 to limit the extension pad 726.

[0050] The third embodiment is based on the first and second embodiments. Figure 4 , Figure 5 , Figures 8 to 11 As shown, the screening assembly 4 includes a side plate 44, two of which are provided. The two side plates 44 are fixedly mounted on the surface of the side plate 66, and a top clamping plate 43 and a tensioning support frame 41 are fixedly mounted on the surface of the side plate 44, respectively. The tensioning support frame 41 is fixedly mounted below the top clamping plate 43. Due to different potato seed screening standards, when only the potato seed size is screened, the staff pours the potato seed onto the top of the sub-screen 42. The impact generated when the potato seed falls causes the sub-screen 42 to deform. Since the sub-screen 42 is made of a flexible mesh material and is deformed by the gravity of the falling potato seed, the potato seed bounces on the surface of the sub-screen 42 after falling. The easily deformable elastic mesh can reduce the impact between the potato seed and the screen when it falls, and screen the irregular potato seed when the potato seed bounces, so as to protect the potato seed from damage on the surface of the potato seed. Then the smaller potato seed is vibrated and falls through the holes of the sub-screen 42 and is screened out.

[0051] A bending groove 46 is provided between the opposite surfaces of the top clamping plate 43 and the tensioning support frame 41, and the bending groove 46 is set as a U-shaped groove. A clamping groove 47 is fixedly installed on the surface of the bending groove 46 close to the side plate 44, and the clamping groove 47 is clamped and adapted to the tensioning support frame 41. A bending hook 45 is fixedly installed inside the bending groove 46, and a sub-screen 42 is fixedly installed on the surface of the bending hook 45. The sub-screen 42 is set as a flexible grid material, and the sub-screen 42 is erected between the opposite surfaces of the side plate 44 through the bending hook 45. The top clamping plate 43 and the folding plate 416 limit the bending groove 46, and the bending groove 46 is set to a U-shaped arc shape. When the sub-screen 42 is deformed by force, the bending hook 45 drives the bending groove 46 to slide inside the top clamping plate 43 and the folding plate 416, and the curved surface of the bending groove 46 and the surface of the folding plate 416 generate friction, so as to fix the sub-screen 42 and buffer it from both sides when the sub-screen 42 is subjected to force, so as to avoid the sub-screen 42 from being broken due to friction on the side that is subjected to force for a long time.

[0052] The tensioning support frame 41 includes an inclined frame plate 412, which is fixedly connected to the side plate 44. A folding plate 416 is fixedly installed on the top of the inclined frame plate 412. The folding plate 416 is snap-fitted with the bending groove 46, and the upper surface of the folding plate 416 is slidably fitted with the bending surface of the bending groove 46. When screening the potato seed size and surface smoothness, the staff pulls the bent slots 46 on both sides so that the bent slots 46 are engaged and adapted with the clamping blocks 414 through the engaging slots 47. At this time, the bent slots 46 are arranged in the positioning cavity 411 to stretch and position the sub-screen 42. Since there are three engaging slots 47, the tightness of the sub-screen 42 can be adjusted by engaging different engaging slots 47 with the tensioning support frame 41, thereby changing the elasticity of the sub-screen 42. When the sub-screen 42 is in a taut state, the grid is not easily deformed, and irregular potatoes are difficult to be thrown out from between the grids, so that the tightness of the sub-screen 42 can be adjusted according to different screening standards, thereby improving the utilization rate of the screening equipment and the screening effect.

[0053] A snap-fit ​​seat 413 is fixedly installed on the surface of the inclined frame plate 412 close to the bent slot 46, a positioning cavity 411 is opened inside the snap-fit ​​seat 413, and a snap block 414 and an extrusion sheet 415 are fixedly installed on both sides of the outer surface of the positioning cavity 411, respectively. The snap block 414 is snap-fitted with the snap-fit ​​slot 47, and the extrusion sheet 415 is slidably fitted with the bent slot 46.

[0054] When in use, the staff starts the motor 21 so that the output end of the motor 21 drives the vibrator 8 to transmit the vibration to the surface of the receiving component 6, causing the receiving component 6 to vibrate. At this time, when the staff screens the potato seeds, they pour the potato seeds along the guide component 7 into the receiving component 6 on the side of the lifting frame 1, so that the potato seeds fall to the top of the screening component 4. Since the receiving component 6 is deformed by the gravity of the falling potato seeds, the potato seeds smaller than the sieve holes on the screening component 4 fall into the receiving component 6 below the screening component 4, and as the receiving component 6 continues to vibrate, the fallen potato seeds are transported along the guide tube 5 to the receiving component 6 on the lower layer for secondary screening.

[0055] The staff starts the motor 21 so that the output end of the motor 21 drives the vibrator 8 to rotate, so that the receiving component 6 is subjected to force to generate vibration. When the vibrator 8 is running, since the motor 21 is installed on the outside of the extension frame 63 through the support frame 26, the vibration of the receiving component 6 will cause the motor 21 to shake. At this time, the pad 23 arranged under the motor 21 rotates above the mounting plate 24 with the vibration and squeezes the shock-absorbing spring 22, so that the shock-absorbing spring 22 is forced to shrink and reduce the vibration frequency of the pad 23, thereby protecting the motor 21 and preventing the motor 21 from loosening due to long-term vibration.

[0056] The side plate 66 provides fixed support for the screening assembly 4, and the potato seeds screened out from the screening assembly 4 fall onto the top of the bottom plate 64. As the vibrator 8 vibrates, the screened potato seeds are guided along the guide tube 5 to the screening assembly 4 on the lower layer for secondary screening, so as to facilitate the grading and screening of the potato seeds.

[0057] The staff dumps the potato seeds onto the top of the guide frame plate 71, and the guide frame plate 71 is set at an angle. At this time, the potato seeds slide downward along the inclination angle of the guide frame plate 71. At this time, the sliding potato seeds contact the buffer component 72 and drive the buffer component 72 to rotate downward on the surface of the rotating rod 73, so that the buffer component 72 rotates to contact the inner wall of the baffle 65. The vibrator 8 is set on the outside of the baffle 65. When the buffer component 72 guides the potato seeds, multiple groups of buffer components 72 are squeezed by the potato seeds and vibrated by the vibrator 8 in swinging states with different frequencies. Compared with the traditional material guiding method, the potato seeds are diverted and guided, which speeds up the fluidity of the potato seeds when they slide down, and avoids blockage when the potato seeds are guided.

[0058] The connecting plate 74 is fixedly installed on the top side of the baffle 65 . Three groups of buffer components 72 are provided. The three groups of buffer components 72 are all adapted to be knocked with the baffle 65 .

[0059] When the potato seed slides down, it impacts the extension pad 726, so that the extension pad 726 is forced to drive the sleeve 721 to rotate downward on the surface of the rotating rod 73, so that the knocking plate 723 is against the inner wall of the baffle 65 and transmits the vibration transmitted by the vibrator 8. An extrusion cavity 725 is arranged in the extension pad 726 to cushion the sliding potato seed. At the same time, the extension pad 726 is forced to be depressed downward to squeeze the extrusion cavity 725, so that the bottom of the extension pad 726 collides with the knocking ball 727 to limit the extension pad 726.

[0060] The staff pours the potato seeds onto the top of the sub-screen 42. The impact generated when the potato seeds fall causes the sub-screen 42 to deform. Since the sub-screen 42 is made of a flexible mesh material and is deformed by the gravity of the falling potato seeds, the potato seeds bounce on the surface of the sub-screen 42 after falling. The easily deformable elastic mesh can reduce the impact between the potato seeds and the screen when they fall, and screen the irregular potato seeds when the potato seeds bounce, so as to protect the potato seeds from damage on the surface of the potato seeds, and then the smaller potato seeds are vibrated and fall through the holes of the sub-screen 42 to be screened out.

[0061] The top clamping plate 43 and the folding plate 416 limit the bending groove 46, and the bending groove 46 is set to a U-shaped arc shape. When the sub-screen 42 is deformed by force, the bending hook 45 drives the bending groove 46 to slide inside the top clamping plate 43 and the folding plate 416, and the curved surface of the bending groove 46 and the surface of the folding plate 416 generate friction, so as to fix the sub-screen 42 and buffer it from both sides when the sub-screen 42 is subjected to force, so as to avoid the sub-screen 42 from being broken due to friction on the side that is subjected to force for a long time.
