Description

Technical Field

[0001] This invention relates to the field of screening equipment technology, and in particular to an automated processing device and method for corn seeds. Background Technology

[0002] In agricultural production, corn is an important food and cash crop, and the quality of its seeds directly affects subsequent germination rate, growth status, and final yield. Screening corn seeds to remove substandard seeds (such as shriveled, broken, and impurity seeds) and retaining plump, intact, high-quality seeds is a crucial step in ensuring the profitability of corn cultivation. Therefore, the screening function in automated corn seed processing equipment plays a vital role in improving agricultural production efficiency and guaranteeing seed quality.

[0003] Currently, commercially available automated corn seed processing equipment has significant shortcomings in the screening stage. These devices mostly use fixed screening cylinders, where seeds slide naturally under gravity through rotation or tilting of the cylinder, and are screened using different sized sieve openings. However, this screening method results in a low frequency of movement of corn seeds within the cylinder, leading to insufficient relative movement between qualified and unqualified seeds. Due to this insufficient movement frequency, unqualified corn seeds (especially small, shriveled, or broken seeds) cannot quickly and fully contact the sieve openings and pass through, easily mixing with qualified seeds, resulting in unsatisfactory screening effects. Simultaneously, the low movement frequency prolongs the residence time of seeds within the cylinder, reducing the screening volume per unit time and severely impacting screening efficiency. In large-scale corn seed processing operations, this deficiency leads to incomplete screening of high-quality seeds, increasing subsequent planting costs and risks, and failing to meet the demands of agricultural production for efficient processing. Therefore, improvements are urgently needed. Summary of the Invention

[0060] Reference Figures 1 to 10 The present invention provides a further description of an automated processing device and method for corn seeds.

[0061] An automated processing device for corn seeds includes a support frame 1 and a screening frame 2 fixedly mounted on the support frame 1. A control device 3 is mounted on the screening frame 2. A partition 4 is fixedly mounted inside the screening frame 2, dividing the interior of the screening frame 2 into a screening section 5 and a discharge section 6. Multiple evenly distributed slots 7 are provided on the partition 4. A first discharge hopper 8 communicating with the screening section 5 is fixedly mounted on the screening frame 2, and a second discharge hopper 9 communicating with the discharge section 6 is fixedly mounted on the screening frame 2. An annular positioning groove 10 is provided at the end of the screening frame 2 away from the partition 4. A screening screen cylinder 11 is mounted on the partition 4, with one end of the screening screen cylinder 11 inserted into the annular positioning groove 10. The annular positioning groove 10 facilitates the positioning of the screening screen cylinder 11 within the screening frame 2 when the operator replaces it. This facilitates quick installation of the screening cylinder 11 by the staff. The screening cylinder 11 has evenly distributed locking blocks 12 on the surface away from the annular positioning groove 10. The screening cylinder 11 is detachably fixed to the partition plate 4 through the locking blocks 12. The end of the screening frame 2 away from the drive box 18 is provided with a frame door 49 that is rotatably connected to the screening frame 2. The frame door 49 facilitates the replacement of the screening cylinder 11 by the staff. A connecting rod 13 is fixedly provided on the locking block 12. A baffle plate 14 is fixedly provided on the end of the connecting rod 13 away from the locking block 12. A feeding pipe 15 connected to the discharge area 6 is provided on the end of the screening frame 2 away from the partition plate 4. An inlet pipe 16 is fixedly provided on the feeding pipe 15. A transmission box 17 is provided on the end of the feeding pipe 15 away from the screening frame 2. A drive box 18 is provided on the transmission box 17.

[0062] The drive housing 18 is provided with a drive unit that is electrically connected to the control device 3. The drive unit includes:

[0063] The drive motor 19 is fixedly mounted on the drive box 18 and electrically connected to the control device 3, and the output end of the drive motor 19 extends into the drive box 18.

[0064] The drive bevel gear 20 is located inside the drive housing 18 and is fixedly connected to the output end of the drive motor 19.

[0065] The transmission box 17 is equipped with a conveying section for conveying corn seeds to the screening section 5. The conveying section includes:

[0066] The drive shaft 21 is rotatably mounted on the transmission box 17, and a driven bevel gear 22 that meshes with the driving bevel gear 20 is fixedly mounted at one end of the drive shaft 21 located in the drive box 18. A connecting sleeve 23 is fixedly mounted at one end of the drive shaft 21 located inside the transmission box 17.

[0067] The conveying shaft 24 is rotatably mounted on the transmission box 17, and one end of the conveying shaft 24 extends into the transmission box 17 and is inserted into the connecting sleeve 23. The surface of the conveying shaft 24 located on the feeding pipe 15 is provided with spiral blades 25.

[0068] During operation, the corn seeds to be screened are fed into the feeding pipe 15 through the feeding pipe 16. Then, the drive motor 19 is started by the control device 3, which causes the drive gear fixedly connected to the output end of the drive motor 19 to rotate. Through the meshing between the drive bevel gear 20 and the driven bevel gear 22, the driven bevel gear 22 rotates, which drives the transmission shaft 21 fixedly connected to the driven bevel gear 22 to rotate. This causes the connecting sleeve 23 fixedly connected to the transmission shaft 21 to rotate. Through the cooperation between the connecting sleeve 23 and the conveying shaft 24, the conveying shaft 24 rotates, which causes the spiral blades 25 set on the conveying shaft 24 to transport the corn seeds entering the feeding pipe 15 to the screening section 5.

[0069] This device is equipped with a conveying unit, which enables it to automatically transport the corn seeds to be screened into the screening section 5 of the screening frame 2, thereby facilitating the subsequent screening operation of the corn seeds and improving the screening efficiency of the device to a certain extent.

[0070] The conveyor section is equipped with a screening mechanism for screening corn seeds. The screening mechanism includes:

[0071] The screening shaft 26 is located in the screening section 5 and is fixedly connected to the end of the conveying shaft 24 near the partition 4. Multiple evenly distributed fixing rings 27 are provided on the screening shaft 26, and multiple evenly distributed connecting blocks 28 are provided on the fixing rings 27. A limit block 29 is provided at the end of the connecting block 28 away from the axis of the fixing ring 27.

[0072] The support portion has multiple sets, and the number of sets of the support portion is consistent with the number of connecting blocks 28 on a single fixing ring 27. The support portion includes:

[0073] The bearing plate 30 has a number of reciprocating grooves 31 on its surface near the axis of the fixed ring 27, which are the same as the number of fixed rings 27. The reciprocating grooves 31 have a limiting groove 32 that is slidably connected to the limiting block 29. The sliding connection between the limiting block 29 and the limiting groove 32 prevents the bearing plate 30 from shaking when it rotates around the screening shaft 26.

[0074] The fixed rod 33 is fixedly installed in the reciprocating groove 31 and slidably connected to the connecting block 28. Two symmetrically arranged first springs 34 are sleeved on the fixed rod 33. The first springs 34 are always in a compressed state. By setting the first springs 34, the frequency of the bearing plate 30 reciprocating in the axial direction of the screening shaft 26 is increased, thereby improving the screening effect of the device on corn seeds to a certain extent.

[0075] The fixed shaft 35 is fixedly mounted on the bearing plate 30.

[0076] A reciprocating part, disposed on the bearing part, is used to drive the bearing part to reciprocate along the axis of the fixed ring 27. The reciprocating part includes:

[0077] The first connecting block 36 is fixedly disposed at the end of the bearing plate 30 away from the partition plate 4, and the surface of the first connecting block 36 away from the partition plate 4 is fixedly connected to the first connecting rod 37.

[0078] Multiple arc-shaped fixing blocks 38 are evenly arranged on the surface of the sieve partition 5 away from the partition plate 4.

[0079] Wheel plate 39 is fixedly installed at the end of the first connecting rod 37 away from the partition plate 4, and a roller 40 that cooperates with the arc-shaped fixing block 38 is rotatably installed on wheel plate 39.

[0080] After the corn seeds enter the screening section 5, the rotation of the conveyor shaft 24 drives the screening shaft 26, which is fixedly connected to the conveyor shaft 24, to rotate. This causes the fixing ring 27, which is mounted on the screening shaft 26, to rotate with the screening shaft 26. Consequently, the connecting block 28, which is mounted on the fixing ring 27, rotates around the axis of the fixing ring 27. This causes the fixing rod 33, which is slidably connected to the connecting block 28, to rotate around the axis of the fixing ring 27. Consequently, the bearing plate 30, which is fixedly connected to the fixing rod 33, rotates around the axis of the fixing ring 27. This, in turn, causes the fixing shaft 35, which is fixedly connected to the bearing plate 30, to rotate around the axis of the fixing ring 27. This causes the screening plates 41, which are rotatably connected to the fixed shaft 35, to rotate around the axis of the fixed ring 27. When each screening plate 41 rotates around the axis of the fixed ring 27, it agitates the corn seeds falling on the screening cylinder 11 in the screening section 5, thereby enabling the corn seeds falling on the screening cylinder 11 to move continuously in the screening cylinder 11. Unqualified corn seeds fall into the first discharge hopper 8 below through the screening cylinder 11, thereby being discharged from the screening frame 2. The corn seeds that have been screened enter the discharge area 6 and are then discharged from the screening frame 2 through the second discharge hopper 9, thus realizing the screening operation of corn seeds.

[0081] When the bearing plate 30 rotates around the axis of the fixed ring 27, it drives the first connecting rod 37, which is fixedly connected to the bearing plate 30, to rotate around the axis of the fixed ring 27. This causes the wheel plate 39, which is fixedly connected to the first connecting rod 37, to rotate around the axis of the fixed ring 27. Consequently, the roller 40, which is rotatably connected to the wheel plate 39, rotates around the axis of the fixed ring 27. When the roller 40 passes the arc-shaped fixing block 38, it causes the roller 40 to drive the wheel plate 39 to reciprocate in the direction of the axis of the conveying shaft 24. This, in turn, causes the roller 40, which is fixedly connected to the wheel plate 39, to reciprocate. The first connecting rod 37 drives the first connecting block 36 to reciprocate in the direction of the conveying shaft 24 axis, thereby driving the bearing plate 30, which is fixedly connected to the first connecting block 36, to reciprocate in the direction of the conveying shaft 24 axis, which in turn causes the screening plate 41, which is rotatably connected to the fixed shaft 35, to reciprocate in the direction of the conveying shaft 24 axis. Thus, while the bearing plate 30 and the screening plate 41 rotate around the conveying shaft 24 axis, they also reciprocate in the direction of the conveying shaft 24 axis, thereby increasing the contact frequency between the bearing plate 30 and the screening plate 41 and the corn seeds.

[0082] This device, by incorporating a reciprocating section, increases the movement frequency of corn seeds within the screening cylinder 11. This, in turn, increases the relative movement frequency between qualified and unqualified corn seeds, allowing unqualified corn seeds to pass through the screening cylinder 11 more easily. Consequently, this improves the screening effect and efficiency of the device.

[0083] A screening section, located on the support section, is used to agitate the corn seeds entering screening section 5. The screening section includes:

[0084] The sieve plate 41 is rotatably mounted on the fixed shaft 35, and in the initial state, the sieve plate 41 is parallel to the axis of the fixed ring 27. The sieve plate 41 is used to stir the corn seeds entering the sieve section 5.

[0085] An adjusting unit, disposed on the bearing unit, is electrically connected to the control device 3. The adjusting unit is used to adjust the included angle between the axis of the screening plate 41 and the fixed ring 27. The adjusting unit includes:

[0086] A fixed frame 42 is fixedly installed on the support plate 30. A limit rod 43 is fixedly installed inside the fixed frame 42. A sliding block 44 is slidably installed inside the fixed frame 42. The sliding block 44 is slidably connected to the limit rod 43. A C-shaped plate 45 is fixedly installed on the surface of the sliding block 44 near the support plate 30.

[0087] The second spring 46 is sleeved on the limiting rod 43, and the second spring 46 is always in a compressed state in the initial state. By setting the second spring 46, it is easy to reset the sliding block 44.

[0088] An electric push rod 47 is fixedly mounted on a fixed frame 42 and electrically connected to a control device 3. The electric push rod 47 is used to push the sliding block 44 to slide within the fixed frame 42.

[0089] The second connecting block 48 is rotatably mounted on the C-shaped plate 45, and the end of the second connecting block 48 near the screening plate 41 is fixedly connected to the screening plate 41.

[0090] When it is necessary to extend the screening time of corn seeds in the screening cylinder 11, the control device 3 controls the adjustment unit to start, thereby adjusting the screening time of corn seeds in the screening cylinder 11. The specific process is as follows: the control device 3 controls the electric push rod 47 to start, so that the electric push rod 47 pushes the sliding block 44 to slide in the fixed frame 42, thereby moving the C-shaped plate 45 fixedly connected to the sliding block 44, which drives the second connecting block 48 rotatably connected to the C-shaped plate 45 to move, thereby driving the screening plate 41 to rotate around the fixed axis 35 by a corresponding angle, thereby changing the angle between the screening plate 41 and the axis of the fixed ring 27, and thus changing the screening time of corn seeds in the screening cylinder 11.

[0091] This device is equipped with an adjustment unit, which allows the angle between the axis of the screening plate 41 and the fixed ring 27 to be adjusted, thereby adjusting the inclination of the screening plate 41 and controlling the screening time of corn seeds in the screening cylinder 11. This allows the device to adjust the screening time according to the actual screening requirements of the corn seeds to be screened, which increases the applicability of the device for screening corn seeds and improves the screening effect of the device for corn seeds.

[0092] Reference Figure 11 An automated processing method for corn seeds, employing automated processing equipment, includes the following steps:

[0093] S1, corn seeds are fed into the feeding pipe 15 through the feeding pipe 16, and then the corn seeds are transported to the screening cylinder 11 in the screening section 5 through the conveying part;

[0094] S2, after the screening section has screened the corn seeds entering the screening section 5 for a period of time, the angle between the screening plate 41 and the axis of the fixed ring 27 is adjusted by the adjustment section so that the screened corn seeds are discharged to the discharge area 6.

[0095] S3, the screening mechanism performs screening operation on the corn seeds entering the screening section 5. The screened corn seeds are discharged from the screening section 5 through the first discharge hopper 8, and the corn seeds in the discharge section 6 are discharged from the discharge section 6 through the second discharge hopper 9.

[0096] Working principle: During operation, the corn seeds to be screened are fed into the feeding pipe 15 through the feeding pipe 16. Then, the drive motor 19 is started by the control device 3, which causes the drive gear fixedly connected to the output end of the drive motor 19 to rotate. Through the meshing between the drive bevel gear 20 and the driven bevel gear 22, the driven bevel gear 22 rotates, which drives the transmission shaft 21 fixedly connected to the driven bevel gear 22 to rotate. This causes the connecting sleeve 23 fixedly connected to the transmission shaft 21 to rotate. Through the cooperation between the connecting sleeve 23 and the conveying shaft 24, the conveying shaft 24 rotates, which causes the spiral blades 25 set on the conveying shaft 24 to transport the corn seeds entering the feeding pipe 15 to the screening section 5.

[0097] After the corn seeds enter the screening section 5, the rotation of the conveyor shaft 24 drives the screening shaft 26, which is fixedly connected to the conveyor shaft 24, to rotate. This causes the fixing ring 27, which is mounted on the screening shaft 26, to rotate with the screening shaft 26. Consequently, the connecting block 28, which is mounted on the fixing ring 27, rotates around the axis of the fixing ring 27. This causes the fixing rod 33, which is slidably connected to the connecting block 28, to rotate around the axis of the fixing ring 27. Consequently, the bearing plate 30, which is fixedly connected to the fixing rod 33, rotates around the axis of the fixing ring 27. This, in turn, causes the fixing shaft 35, which is fixedly connected to the bearing plate 30, to rotate around the axis of the fixing ring 27. This causes the screening plates 41, which are rotatably connected to the fixed shaft 35, to rotate around the axis of the fixed ring 27. When each screening plate 41 rotates around the axis of the fixed ring 27, it agitates the corn seeds falling on the screening cylinder 11 in the screening section 5, thereby enabling the corn seeds falling on the screening cylinder 11 to move continuously in the screening cylinder 11. Unqualified corn seeds fall into the first discharge hopper 8 below through the screening cylinder 11, thereby being discharged from the screening frame 2. The corn seeds that have been screened enter the discharge area 6 and are then discharged from the screening frame 2 through the second discharge hopper 9, thus realizing the screening operation of corn seeds.

[0098] When the bearing plate 30 rotates around the axis of the fixed ring 27, it drives the first connecting rod 37, which is fixedly connected to the bearing plate 30, to rotate around the axis of the fixed ring 27. This causes the wheel plate 39, which is fixedly connected to the first connecting rod 37, to rotate around the axis of the fixed ring 27. Consequently, the roller 40, which is rotatably connected to the wheel plate 39, rotates around the axis of the fixed ring 27. When the roller 40 passes the arc-shaped fixing block 38, it causes the roller 40 to drive the wheel plate 39 to reciprocate in the direction of the axis of the conveying shaft 24. This, in turn, causes the roller 40, which is fixedly connected to the wheel plate 39, to reciprocate. The first connecting rod 37 drives the first connecting block 36 to reciprocate in the direction of the conveying shaft 24 axis, thereby driving the bearing plate 30, which is fixedly connected to the first connecting block 36, to reciprocate in the direction of the conveying shaft 24 axis, which in turn causes the screening plate 41, which is rotatably connected to the fixed shaft 35, to reciprocate in the direction of the conveying shaft 24 axis. Thus, while the bearing plate 30 and the screening plate 41 rotate around the conveying shaft 24 axis, they also reciprocate in the direction of the conveying shaft 24 axis, thereby increasing the contact frequency between the bearing plate 30 and the screening plate 41 and the corn seeds.

[0099] When it is necessary to extend the screening time of corn seeds in the screening cylinder 11, the control device 3 controls the adjustment unit to start, thereby adjusting the screening time of corn seeds in the screening cylinder 11. The specific process is as follows: the control device 3 controls the electric push rod 47 to start, so that the electric push rod 47 pushes the sliding block 44 to slide in the fixed frame 42, thereby causing the C-shaped plate 45 fixedly connected to the sliding block 44 to move, which drives the second connecting block 48 rotatably connected to the C-shaped plate 45 to move, thereby causing the screening plate 41 to rotate around the fixed axis 35 by a corresponding angle, thereby changing the angle between the screening plate 41 and the axis of the fixed ring 27, and thus changing the screening time of corn seeds in the screening cylinder 11.
