DETAILED DESCRIPTION

[0028] See also Figure 1-Figure 10 In an embodiment of the present invention, a grain ear grain separation device includes a grain screen plate 1, grain ear slide plates 3 are arranged at both ends of the grain screen plate 1, a grain ear drop hopper 4 is arranged below the end of the grain ear slide plate 3 away from the grain screen plate 1, a grain support plate 5 is arranged below the grain screen plate 1, and grain drop hoppers 6 are arranged at both ends of the grain support plate 5, chains 7 are symmetrically arranged along the center on both sides of the grain screen plate 1, multiple groups of scrapers 2 are arranged in an array on the chain 7, and a cleaning component is arranged at the bottom of the scraper 2. When the chain 7 rotates, the scraper 2 is driven to move toward the grain ear slide plate 3 at the top of the grain screen plate 1, and when the scraper 2 moves, the cleaning component rotates.

[0029] The grain screen plate 1 and the ear slide plate 3 are installed with a shell on the periphery, and the end of the ear slide plate 3 away from the grain screen plate 1 is symmetrically provided with grooves for the chain 7 to pass through, and a sprocket for driving the chain 7 to rotate is provided below the corresponding groove of the ear slide plate 3, and an inclined surface is provided at the end of the ear slide plate 3 away from the grain screen plate 1, so as to facilitate the ears to slide into the ear drop hopper 4, the chain 7 is a runway-shaped closed-loop structure, and the grain screen plate 1 and the ear slide plate 3 are in the chain 7, and the grain support plate 5 is below the chain 7, the end of the scraper 2 close to the chain 7 is slidably matched with the grain screen plate 1 and the ear slide plate 3, and the end of the scraper 2 away from the chain 7 is slidably matched with the top of the grain support plate 5, and the grain support plate 5 is assembled on the shell, and the number of grain drop hoppers 6 can be set according to actual needs, and a motor for driving the sprocket to rotate is provided on the shell.

[0030] In actual use, when it is necessary to dry corn cobs, because corn cobs will inevitably have grains falling off during the harvesting process, causing the two to mix, and because the drying time of the grains and cobs is inconsistent, after the cobs and the fallen seeds fall onto the grain sieve plate 1, the motor is then started to drive the sprocket to rotate, thereby rotating the chain 7, and the rotation of the chain 7 causes the scraper 2 thereon to be transported to the right, and the bottom of the scraper 2 and the top of the grain sieve plate 1 slide and fit, and during the transportation process, the grains pass through the grain sieve plate 1 and fall onto the grain support plate 5, while the cobs are scraped by the scraper 2 The seeds are pushed onto the ear slide plate 3 and then fall into the ear drop hopper 4, while the grains that fall on the grain support plate 5 are scraped into the grain drop hopper 6 under the continuous movement of the scraper 2, thereby achieving that under the action of the grain screen plate 1, the grains fall on the grain support plate 5 and are transported to the grain drop hopper 6 through the scraper 2, and the ear is transported to the ear drop hopper 4 through the scraper 2, thus completing the separation and separate collection of the ear and the grain. After the collection, the ear enters the ear drying chamber, and the grain enters the grain drying chamber, and then the ear and the grain can be dried separately, which has simple operation, high work efficiency and high seed yield.

[0031] See also Figure 2-Figure 4 Preferably, the scraper 2 includes an inner plate 202; a first outer plate 201 and a second outer plate 203 are respectively provided on both sides of the inner plate 202; a mounting groove is provided along the center of the bottom of the first outer plate 201, the inner plate 202, and the second outer plate 203; a mounting seat is fixedly provided in the mounting groove; the mounting seat is assembled and connected with the chain 7; the cleaning component is installed and provided at the bottom of the inner plate 202; when actually used, when the scraper 2 is at the top of the grain screen plate 1, the first outer plate 201 is installed and provided On the right side of the inner plate 202, the second outer plate 203 is installed on the left side of the inner plate 202, and there is a gap between the bottom of the inner plate 202, the second outer plate 203 and the grain screen plate 1, and the bottom of the first outer plate 201 and the top of the grain screen plate 1 are slidingly fitted, that is, the bottom height of the first outer plate 201 is lower than the bottom height of the inner plate 202 and the second outer plate 203, so that when the chain 7 rotates, the ears and grains on the grain screen plate 1 can be transported through the first outer plate 201.

[0032] See also Figure 4-Figure 6Preferably, the cleaning assembly includes a rotating shaft 10; rollers 9 are fixedly arranged at both ends of the rotating shaft 10, and a plurality of push rods 12 are arranged in a horizontal array on the rotating shaft 10. A fixed plate 15 is rotatably connected to the outer periphery of the end of the rotating shaft 10 close to the roller 9. The fixed plate 15 is fixedly connected to the inner plate 202, and a bottom plate 14 corresponding to the roller 9 is arranged on the top of the grain sieve plate 1. In actual use, two groups of fixed plates 15 are symmetrically arranged along the center of the rotating shaft 10, and two groups of bottom plates 14 are symmetrically arranged along the center of the grain sieve plate 1. When the roller 9 is at the top of the grain sieve plate 1, the roller 9 corresponds to the bottom plate 14, and when the chain 7 rotates, the roller 9 rotates through the friction between the bottom plate 14. Of course, the top of the bottom plate 14 The part can be provided with grooves or protrusions for increasing the friction between the roller 9 and the roller 9, so that the roller 9 can rotate effectively. In addition, the number and position of the push rods 12 correspond to the sieve holes on the grain screen plate 1 one by one, and the size of the push rods 12 is smaller than the size of the sieve holes. In this way, after the push rods 12 are extended into the sieve holes, as the rotating shaft 10 rotates, the push rods 12 will not conflict with the sieve holes. The sieve holes on the grain screen plate 1 are arranged in a square array. When the roller 9 rotates, the roller 9 drives the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 enables the push rods 12 to clear the sieve holes on the grain screen plate 1 one by one to avoid them being blocked by grains. Even if there are blocked grains in the sieve holes, they will be pushed down onto the grain support plate 5 by the push rods 12.

[0033] Furthermore, preferably, the push rod 12 is slidably connected to the rotating shaft 10, and a cover plate 11 slidably adapted to the push rod 12 is fixedly provided at the bottom of one side of the inner plate 202 close to the second outer plate 203, and the number and position of the cover plates 11 correspond one-to-one with the push rod 12, the cover plate 11 is a quarter-circular ring structure, and the top of the cover plate 11 corresponds to the top of the rotating shaft 10, and the end of the cover plate 11 away from the first outer plate 201 matches the rotation trajectory of the push rod 12 after it extends out of the rotating shaft 10 to the maximum, and the side walls of the inner plate 202 and the first outer plate 201 are provided with avoidance grooves 13 for the rotation of the push rod 12, thereby avoiding the problem that the push rod 12 may get stuck. In actual use, when the rotating shaft 10 is When the roller 9 rotates clockwise under the action of the rotating shaft 10, the push rod 12 rotates clockwise with the rotating shaft 10. When the push rod 12 rotates, under the action of the cover plate 11, when the push rod 12 is in a vertical state relative to the top of the push rod 12, the top of the push rod 12 cooperates with the top of the cover plate 11, and the bottom end of the push rod 12 extends out of the rotating shaft 10 at the maximum, that is, the push rod 12 extends into the sieve hole at the maximum, thereby effectively ejecting the grains blocked in the sieve hole, and then the rotating shaft 10 continues to rotate and moves to the right side of the ear slide plate 3. In this process, the push rod 12 rotates and moves out of the current group of sieve holes with the rotating shaft 10, and the end of the push rod 12 separated from the cover plate 11 moves to the next group of sieve holes, and the sieve holes on the grain sieve plate 1 are cleaned in this reciprocating manner.

[0034] See also Figure 7-Figure 8Preferably, a cavity is provided at the bottom of the inner plate 202, and the side wall of one end of the fixed plate 15 away from the rotating shaft 10 is fixedly connected to the cavity, a hollow tube 21 is fixedly provided between the two groups of fixed plates 15, and a reciprocating screw 17 is rotatably provided between the top ends of the two groups of fixed plates 15, and a reciprocating plate 18 is rotatably provided on the reciprocating screw 17 along the center, and two groups of reciprocating threads on the reciprocating screw 17 are symmetrically provided along the center, so that when the reciprocating screw 17 rotates, the two groups of reciprocating plates 18 can be synchronously moved closer or farther on the reciprocating screw 17, and the reciprocating plate 18 and the rotating shaft 10 are connected by a belt drive, and the rotating shaft 10 and the push rod 12 are both hollow structures, and the push rod 12 and the rotating shaft are connected by a belt drive. 10 is connected, and a pneumatic component is arranged in the cavity. In actual use, the pneumatic component is connected with the rotating shaft 10. When the rotating shaft 10 rotates to drive the reciprocating screw 17 to rotate, the reciprocating screw 17 drives the reciprocating plate 18 to reciprocate on the reciprocating screw 17. The movement of the reciprocating plate 18 drives the pneumatic component to transport gas into the rotating shaft 10. The gas entering the rotating shaft 10 is then ejected through the push rod 12, so as to realize the process of one end of the push rod 12 extending into the sieve hole, and the sieve hole is jetted. On the one hand, it accelerates the ejection of the stuck grains in the sieve hole, and on the other hand, the inner wall of the sieve hole is cleaned, thereby avoiding the possible breakage of the wet grains, causing them to adhere to the inner wall of the sieve hole, which is easy to cause blockage.

[0035] Further, preferably, the pneumatic assembly includes a second telescopic tube 20; the second telescopic tube 20 is arranged between the two groups of reciprocating plates 18, and the reciprocating plate 18 is arranged between the reciprocating plate 18 and the fixed plate 15. A hollow tube 21 is arranged below the second telescopic tube 20, and both ends of the hollow tube 21 are respectively fixedly connected to the fixed plate 15. The second telescopic tube 20 and the hollow tube 21 are connected through the first air pipe. In actual use, the fixed plate 15 includes a circular ring and a straight plate, the circular ring is rotatably connected to the periphery of the rotating shaft 10, and the inner ring side wall of the circular ring is provided with an annular cavity, the straight plate is fixedly arranged at the top position of the circular ring, and the conveying path is arranged at the bottom of the straight plate, and the conveying path and the circular ring are connected to the outer ring of the rotating shaft 10. The cavities are connected, and a through hole connected to the circular cavity is provided on the side wall of the rotating shaft 10. The first telescopic tube 19 and the top of the conveying path are connected through the second air pipe. In this way, when the reciprocating screw 17 rotates, the two groups of reciprocating plates 18 reciprocate on the reciprocating screw 17. In this process, the two groups of reciprocating plates 18 approach each other and squeeze the second telescopic tube 20 to contract, so that the gas in the second telescopic tube 20 is transported to the rotating shaft 10 through the first air pipe, the hollow tube 21, the conveying path, and the circular cavity and ejected through the push rod 12. Similarly, when the reciprocating plates 18 move away from each other, the reciprocating plates 18 squeeze the first telescopic tube 19 so that the gas therein is transported to the rotating shaft 10.

[0036] Furthermore, preferably, a first one-way valve is provided in each of the first air pipe and the second air pipe, and a second one-way valve connected to the outside is provided on each of the first telescopic tube 19 and the second telescopic tube 20. In actual use, the first one-way valve in the first air pipe and the second air pipe is used to only transport gas into the delivery channel, and the gas in the delivery channel will not be transported to the first air pipe and the second air pipe. Similarly, the second one-way valve on the first telescopic tube 19 and the second telescopic tube 20 is used to only allow gas to enter but not exit. In this way, during the reciprocating movement of the two sets of reciprocating plates 18, gas is continuously transported into the rotating shaft 10 through the first telescopic tube 19 and the second telescopic tube 20.

[0037] See also Figure 8-Figure 9 Preferably, a square opening connected to the rotating shaft 10 is provided on the middle side wall of the push rod 12, and a support plate 26 is fixedly provided at the center of the push rod 12, and pads are elastically connected to the upper and lower sides of the support plate 26 through springs, and a round rod 27 is fixedly connected to the top center of the pad, and a piston 25 is fixedly provided at one end of the round rod 27 away from the pad, and sealing plates 24 are fixedly provided at both ends of the pad, and the sealing plates 24 are slidably connected to the side walls of the push rod 12. In actual use, the size of the piston 25 is smaller than the size of the inner wall of the push rod 12, and circular ring structures that are slidably adapted to the push rod 12 are provided at both ends of the push rod 12, so that when the piston 25 moves to the end of the push rod 12, the end of the push rod 12 can be blocked, and a convex plate is provided on the side wall of the end of the sealing plate 24 away from the rotating shaft 10, Thereby, the problem of the push rod 12 slipping off the rotating shaft 10 is avoided, and when in use, when one end of the push rod 12 extends out of the rotating shaft 10 to the maximum, the sealing plate 24 moves to seal the square opening extending out of the rotating shaft 10 to prevent the gas from flowing directly to the outside through the square opening; when one end of the push rod 12 is rotated to a vertical state on the cover plate 11, the push rod 12 moves downward under the action of the cover plate 11, that is, the other end of the push rod 12 extends out of the rotating shaft 10 to the maximum. At this time, the sealing plate 24 on the top side wall of the push rod 12 slides with the periphery of the rotating shaft 10, so that the sealing plate 24 moves upward relative to the push rod 12, and then the piston 25 moves to the top position of the push rod 12, blocks the top of the push rod 12, and then the gas can only be ejected through the bottom opening of the push rod 12.

[0038] See also Figure 3 , Figure 7 , Fig.10Preferably, a push plate 8 is slidably provided on the side wall of the first outer plate 201, and a connecting plate 22 is symmetrically rotated along the center on one side of the push plate 8 close to the inner plate 202, and a driving block 23 is rotatably provided on the end of the connecting plate 22 away from the push plate 8, and the driving block 23 is slidably connected to the side wall of the inner plate 202, and a fixed block 16 is provided on the central periphery of the reciprocating screw rod 17, and the top of the fixed block 16 is fixedly connected to the cavity, and the bottom height of the fixed block 16 is slightly higher than the top height of the driving block 23, and a wedge block 28 is elastically connected to the top of the driving block 23, and a slope facing the fixed block 16 is provided on the wedge block 28, and a notch 29 corresponding to and slidingly adapted to the driving block 23 is provided on the side of the reciprocating plate 18 close to the push plate 8.

[0039] In actual use, an elastic column or elastic pull rope is provided between the fixed block 16 and the push plate 8, so that the push plate 8 can reset itself after moving. The side of the driving block 23 close to the reciprocating plate 18 is provided with a protruding structure and is slidably adapted to the notch 29. In the initial state, the push plate 8 is retracted in the first outer plate 201, the driving block 23 is on the side of the reciprocating plate 18 close to the fixed block 16, and the wedge block 28 protrudes from the top of the driving block 23, and the connecting plate 22 is in an inclined state, the reciprocating plate 18 is close to the periphery of the fixed plate 15, and the first telescopic tube 19 The second telescopic tube 20 is in a contracted state, the second telescopic tube 20 is in an expanded state, and the push rod 12 is in a state of tilting to the right; when the chain 7 is started to rotate, the chain 7 rotates to move the scraper 2, and then the roller 9 cooperates with the bottom plate 14 to rotate the shaft 10, and the rotation of the shaft 10 drives the push rod 12 to rotate, and the push rod 12 rotates to clean the sieve holes on the grain sieve plate 1, and at the same time, the reciprocating screw rod 17 is driven by the belt to rotate, and the reciprocating screw rod 17 rotates to make the reciprocating plate 18 reciprocate, and then reciprocate with the first telescopic tube 19 and the second telescopic tube 20 to squeeze During the reciprocating movement of the reciprocating plate 18, the reciprocating plate 18 pushes the driving block 23 to move toward the fixed block 16 through the wedge block 28, and then pushes the pushing plate 8 to extend out of the side wall of the first outer plate 201 in the moving direction of the scraper 2 through the connecting plate 22, so that the fruit ears accumulated on one side of the first outer plate 201 due to the movement of the first outer plate 201 or when placed are flattened, thereby achieving effective spreading of the fruit ears, thereby preventing the accumulated fruit ears from being unable to effectively pass through the grain screen plate 1 to complete the filtering and separation of the grains during the transportation process. When the fixed block 16 is moved to the position, the wedge block 28 is adapted to the sliding of the fixed block 16, and the wedge block 28 is contracted in the driving block 23 under the action of the fixed block 16. When the reciprocating plate 18 is close to or fitted with the fixed block 16, the push plate 8 moves and resets under the elastic connection between the push plate 8 and the fixed block 16, and then pushes the driving block 23 through the notch 29 through the connecting plate 22 to move and reset.
