Description

Technical Field

[0001] This invention relates to the field of seed counting machine technology, specifically to a precise seed counting machine. Background Technology

[0002] A seed counter is a specialized agricultural or laboratory device designed for the rapid and accurate counting of seeds. It uses photoelectric sensors, image recognition, or other technologies to automate seed quantity counting and is widely used in seed inspection, agricultural production, and scientific research. The main features of a seed counter are high efficiency and precision, significantly improving work efficiency and reducing errors associated with manual counting.

[0003] Seed counting machines typically work by dropping seeds onto a conveyor belt, which then transports them to a storage container. As the seeds fall, they block the light source. This "light-blocking" behavior is captured by a sensitive photodetector and converted into a weak current change, forming an electrical "pulse." This pulse is then recorded by the controller for accurate counting. However, considering that seeds tend to clump together after falling from the hopper, multiple seeds may simultaneously block the light source during the fall. Since the photodetector can only receive one signal, this results in inaccurate counting.

[0004] To address this problem, we propose a precise seed counting machine. Summary of the Invention

[0009] Preferably, the evacuation mechanism includes a mounting frame fixedly connected to the top of the conveyor belt, the mounting frame having a dispersion plate inside, and a plurality of dispersion rods fixedly connected to the bottom of the dispersion plate; Two first piston boxes are symmetrically fixedly connected to the top of the U-shaped enclosure. A transmission pipe is fixedly connected to one side of each first piston box, and a second piston box is fixedly connected to one end of the transmission pipe.

One end of the second piston rod extends through to the inner wall of the mounting frame and is fixedly connected to one side of the dispersion plate.

[0010] Preferably, the vibration mechanism includes a vibration block fixedly connected to one side of the feed pipe, a rebound block provided on one side of the vibration block, two striking rods fixedly connected to one side of the rebound block, a linkage block fixedly connected to the top of the connecting plate, first extrusion blocks fixedly connected to both sides of the linkage block, a second extrusion block provided on one side of the first extrusion block, an extrusion rod fixedly connected to one side of the second extrusion block, one end of the extrusion rod penetrating to one side of the vibration block and fixedly connected to one side of the rebound block, a first tension spring sleeved on the surface of the extrusion rod, one end of the first tension spring fixedly connected to one side of the vibration block, and the other end of the first tension spring fixedly connected to one side of the rebound block.

[0015] Preferably, the controller is a PLC controller and has a built-in counter.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, by setting up a counting mechanism, allows seeds to be transported in a single layer on the conveyor belt after falling from the hopper. The seeds then fall from one end of the conveyor belt. During the falling process, each precise "light blocking" action is converted into a clear electrical pulse when passing between the light source and the photosensitive receiver. This pulse is recorded by the counter built into the controller, which can accurately calculate the number of seeds and improve the accuracy of counting. 2. By setting up a diversion mechanism, the present invention can start a motor, which then drives the lead screw to rotate. The motor drives the toothed plate to move back and forth through the sliding block, connecting rod and connecting plate, so that the toothed plate rotates the toothed ring. This causes the toothed ring and the diversion tube to rotate back and forth in small amplitudes, so that the seeds fall alternately at different positions on the conveyor belt. This avoids the large accumulation of seeds at a single landing point, thereby improving the accuracy of subsequent counting. 3. By setting up an evacuation mechanism, when the connecting plate moves back and forth, the connecting plate will drive the first piston rod and the first piston plate to move through the connecting rod. The first piston plate will drive the second piston plate, the second piston rod and the dispersing plate to move back and forth through the pneumatic transmission. The dispersing rod will then slightly move the seeds on the conveyor belt, which can effectively separate overlapping or sticky seeds into a single layer, greatly improving the accuracy of subsequent light source counting. 4. By setting up a vibration mechanism, when the connecting plate moves, it will drive the linkage block and the first extrusion block to move. The first extrusion block extrudes the inclined surface of the second extrusion block, causing the striking rod to retract. When the first extrusion block and the second extrusion block separate, the striking rod quickly rebounds under the action of the first tension spring and strikes the vibrating block, generating high-frequency vibration. This vibration is transmitted to the feeding pipe, which can effectively prevent seeds from clogging or sticking at the pipe opening and ensure smooth and continuous feeding.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 - Figure 10 As shown, Example 1:

[0021] A precision seed counting machine includes a base 1, and also includes: A U-shaped enclosure 2 is fixedly connected to the top of the base 1. A hopper 3 is provided on the top of the U-shaped enclosure 2. Support rods 4 are provided on both sides of the hopper 3 and are fixedly connected to the U-shaped enclosure 2 through the support rods 4. Two feeding pipes 5 are symmetrically fixedly connected to the bottom of the hopper 3. The counting mechanism is fixedly mounted on the base 1. The counting mechanism can count the number of seeds by means of sensing by the light source 10. The diversion mechanism is fixedly installed on the U-shaped enclosure 2. The diversion mechanism changes the position where the seeds fall by rotating. The evacuation mechanism is fixedly mounted on the counting mechanism. The evacuation mechanism disperses the seeds through piston transmission of the diversion mechanism. The vibration mechanism is fixedly installed on the feed pipe 5. The vibration mechanism generates vibration through the extrusion transmission of the diversion mechanism.

[0022] In this embodiment, a U-shaped enclosure 2, a hopper 3, a counting mechanism, a diversion mechanism, a dispersion mechanism, and a vibration mechanism are set up. The diversion mechanism is responsible for distributing the seed flow to different paths, the dispersion mechanism is responsible for separating overlapping seeds before counting, and the vibration mechanism uses the equipment's own power to assist in feeding. The various mechanisms cooperate and work together to solve the problem of missed counting and miscounting caused by seed aggregation and overlap in traditional seed counting machines, which significantly improves the accuracy and reliability of counting.

[0023] The counting mechanism includes a support frame 6 fixedly connected to the top of the base 1. Two conveyor belts 7 corresponding to the feed pipe 5 are fixedly installed on the top of the support frame 6. A connecting frame 8 is fixedly installed on one side of the conveyor belt 7. A photosensitive receiver 9 is fixedly installed on one side of the connecting frame 8. A light source 10 that works with the photosensitive receiver 9 is fixedly installed at the bottom of the conveyor belt 7. A controller 11 is fixedly installed on one side of the base 1.

[0024] In this embodiment, by setting a counting mechanism, when the seeds fall from the hopper 3 onto the conveyor belt 7, the seeds are spread out in a single layer on the conveyor belt 7 and then fall from one end of the conveyor belt 7. During the falling process, when the seeds pass between the light source 10 and the photosensitive receiver 9, each precise "light blocking" action is converted into a clear electrical pulse and recorded by the built-in counter of the controller 11, which can accurately calculate the number of seeds and improve the accuracy of counting.

[0025] Controller 11 is a PLC controller and has a built-in counter.

[0026] In this embodiment, a PLC controller 11 is used as the main controller 11 and a built-in counter is incorporated, which enables the system to have advantages such as flexible programming, strong anti-interference ability, and high counting accuracy. The PLC controller 11 can easily set the counting threshold, delay parameters, etc., and can work stably and collaboratively with actuators such as motor 14 and photosensitive receiver 9, providing a reliable control core for the automated operation of the entire set of equipment. Example 2:

[0027] The diversion mechanism includes a diversion pipe 12 that is rotatably connected to the surface of the feed pipe 5; A transmission box 13 is fixedly installed on the top of the U-shaped enclosure 2. A motor 14 is fixedly installed on one side of the transmission box 13. The output end of the motor 14 passes through the interior of the transmission box 13 and is fixedly connected to a lead screw 15. A sliding block 16 is connected to the surface of the lead screw 15. A connecting plate 17 is fixedly connected to one side of the transmission box 13. Two toothed plates 18 are fixedly installed on one side of the connecting plate 17. Two connecting rods 19 are fixedly connected to one side of the connecting plate 17. One end of the connecting rod 19 passes through the interior of the transmission box 13 and is fixedly connected to one side of the sliding block 16. A toothed ring 20 that mates with the toothed plates 18 is fixedly connected to the surface of the diverter pipe 12.

[0028] In this embodiment, by setting up a diversion mechanism, the motor 14 is started, and then the motor 14 drives the lead screw 15 to rotate. Through the sliding block 16, the connecting rod 19 and the connecting plate 17, the toothed plate 18 is driven to move back and forth, so that the toothed plate 18 rotates the toothed ring 20. This causes the toothed ring 20 and the diversion pipe 12 to rotate back and forth in small amplitudes, so that the seeds fall alternately at different positions on the conveyor belt 7. This can avoid the large accumulation of seeds at a single landing point, thereby improving the accuracy of subsequent counting.

[0029] The top of the gear ring 20 is provided with a bearing 41, and is rotatably connected to the bottom of the hopper 3 through the bearing 41.

[0030] In this embodiment, by setting a bearing 41 between the top of the gear ring 20 and the bottom of the hopper 3, the diversion pipe 12 can rotate stably and with low resistance around the bottom of the hopper 3. The introduction of the bearing 41 effectively reduces rotational friction, reduces the load on the motor 14, and avoids wear caused by direct contact between the gear ring 20 and the hopper 3, thereby improving the reliability of the diversion mechanism in long-term operation.

[0031] Preferably, one end of the diversion pipe 12 is flat and round, and several diversion plates 42 are fixedly connected to the inner wall.

[0032] In this embodiment, by setting one end of the diversion tube 12 to a flat oval shape and fixing multiple diversion plates 42 to its inner wall, the seeds can be further and evenly dispersed after entering the diversion tube 12. The flat oval outlet expands the seed falling coverage area, while the diversion plates 42 guide the seeds to slide down in different directions, effectively preventing the seeds from accumulating inside the diversion tube 12 and improving the diversion effect; It should be noted that the diverter plates 42 are uniformly arranged circumferentially along the inner wall of the diverter tube 12, and there is a gap of at least one seed diameter between the free ends of each diverter plate 42 to ensure that the seed flow can still be uniformly divided when the diverter tube 12 rotates. Example 3:

[0033] The evacuation mechanism includes a mounting frame 21 fixedly connected to the top of the conveyor belt 7. Inside the mounting frame 21 is a dispersion plate 22, and a number of dispersion rods 23 are fixedly connected to the bottom of the dispersion plate 22. Two first piston boxes 24 are symmetrically fixedly connected to the top of the U-shaped enclosure 2. A transmission pipe 25 is fixedly connected to one side of the first piston box 24, and a second piston box 26 is fixedly connected to one end of the transmission pipe 25. One side of the second piston box 26 is fixedly connected to one side of the mounting frame 21. A first piston plate 27 is slidably connected inside the first piston box 24. A first piston rod 28 is fixedly connected to one side of the first piston plate 27. One end of the first piston rod 28 extends through to one side of the first piston box 24. A connecting rod 29 is provided at the connection between the connecting plate 17 and the first piston rod 28, and they are hinged through the connecting rod 29. A second piston plate 30 is slidably connected to the inner wall of the second piston box 26. A second piston rod 31 is fixedly connected to one side of the second piston plate 30. One end of the second piston rod 31 extends through to the inner wall of the mounting frame 21 and is fixedly connected to one side of the dispersion plate 22.

[0034] In this embodiment, by setting up an evacuation mechanism, when the connecting plate 17 moves back and forth, the connecting plate 17 will drive the first piston rod 28 and the first piston plate 27 to move through the connecting rod 29. The first piston plate 27 will drive the second piston plate 30, the second piston rod 31 and the dispersing plate 22 to move back and forth through pneumatic transmission. The dispersing rod 23 will then slightly move the seeds on the conveyor belt 7, which can effectively separate overlapping or sticky seeds into a single layer, greatly improving the accuracy of subsequent counting by the light source 10.

[0035] A second tension spring 40 is fixedly connected to one side of the second piston plate 30, and one end of the second tension spring 40 is fixedly connected to the inner wall of the second piston box 26.

[0036] In this embodiment, a second tension spring 40 is provided between the second piston plate 30 and the inner wall of the second piston box 26 to provide auxiliary elastic force for the repositioning of the dispersion plate 22. When the pneumatic transmission thrust decreases, the second tension spring 40 can quickly pull the dispersion plate 22 back to its original position, ensuring that the high-frequency reciprocating motion of the dispersion plate 22 is sensitive and reliable, thereby ensuring the continuity of the evacuation effect. Example 4:

[0037] The vibration mechanism includes a vibration block 32 fixedly connected to one side of the feed pipe 5, a rebound block 33 on one side of the vibration block 32, two striking rods 34 fixedly connected to one side of the rebound block 33, a linkage block 35 fixedly connected to the top of the connecting plate 17, a first extrusion block 36 fixedly connected to both sides of the linkage block 35, a second extrusion block 37 on one side of the first extrusion block 36, an extrusion rod 38 fixedly connected to one side of the second extrusion block 37, one end of the extrusion rod 38 extending through to one side of the vibration block 32 and fixedly connected to one side of the rebound block 33, a first tension spring 39 sleeved on the surface of the extrusion rod 38, one end of the first tension spring 39 fixedly connected to one side of the vibration block 32, and the other end of the first tension spring 39 fixedly connected to one side of the rebound block 33.

[0038] In this embodiment, a vibration mechanism is set up so that when the connecting plate 17 moves, it will drive the linkage block 35 and the first extrusion block 36 to move. The first extrusion block 36 extrudes the slope surface of the second extrusion block 37, causing the striking rod 34 to retract. When the first extrusion block 36 separates from the second extrusion block 37, the striking rod 34 quickly rebounds and strikes the vibrating block 32 under the action of the first tension spring 39, generating high-frequency vibration. This vibration is transmitted to the feeding pipe 5, which can effectively prevent seeds from being blocked or stuck at the pipe opening, ensuring smooth and continuous feeding.

[0039] The first extrusion block 36 has an arc-shaped side, while the second extrusion block 37 has sloping sides.

[0040] In this embodiment, by setting one side of the first extrusion block 36 as an arc shape and the two sides of the second extrusion block 37 as ramps, the contact and separation process of the two is smoother and more efficient. The combination of the arc surface and the ramp can reduce jamming and impact noise during the movement process, while reducing wear on parts and improving the stability and service life of the mechanism.

[0041] The working principle and usage process of this invention are as follows: The motor 14 is started, and then the motor 14 drives the lead screw 15 to rotate, causing the sliding block 16 to move back and forth. The sliding block 16 will drive the connecting rod 19, the connecting plate 17 and the toothed plate 18 to move back and forth. When the toothed plate 18 contacts the toothed ring 20, the meshing of the toothed plate 18 and the toothed ring 20 will cause the toothed ring 20 and the diversion pipe 12 to rotate back and forth in a small amplitude. When the seeds in the hopper 3 enter the diversion pipe 12 through the feeding pipe 5, the seeds will fall alternately at different positions on the conveyor belt 7, which can avoid the seeds accumulating in large quantities at a single landing point, thereby improving the accuracy of subsequent counting. When the connecting plate 17 moves back and forth, the connecting plate 17 will drive the first piston rod 28 and the first piston plate 27 to move back and forth left and right through the connecting rod 29. When the first piston plate 27 moves to the side closer to the transmission box 13, the first piston box 24 is under negative pressure. The gas in the second piston box 26 will enter the first piston box 24 through the transmission pipe 25. At this time, the second piston box 26 is also under negative pressure. The second piston plate 30, the second piston rod 31 and the dispersing plate 22 will move to the side closer to the second piston box 26. When the first piston rod 28 is reset, the dispersing rod 23 and other structures will also be reset in the opposite way to the above steps, and the seeds on the conveyor belt 7 will be slightly moved. This can effectively separate the overlapping or sticky seeds into a single layer, which greatly improves the accuracy of the subsequent counting by the light source 10. When the connecting plate 17 moves back and forth, it will drive the linkage block 35 and the first extrusion block 36 to move. When the arc-shaped part of the first extrusion block 36 extrudes the slope of the second extrusion block 37, the second extrusion block 37, the extrusion rod 38, the spring block 33 and the striking rod 34 will retract. When the first extrusion block 36 separates from the second extrusion block 37, the striking rod 34 will quickly rebound and strike the vibrating block 32 under the action of the first tension spring 39, generating high-frequency vibration. This vibration is transmitted to the feeding pipe 5, which can effectively prevent seeds from being blocked or stuck at the pipe opening, and ensure smooth and continuous feeding. Finally, after the seeds fall from the hopper 3 onto the conveyor belt 7, they are spread out in a single layer on the conveyor belt 7 and then fall from one end of the conveyor belt 7. During the falling process, when the seeds pass between the light source 10 and the photosensitive receiver 9, each precise "light blocking" action is converted into a clear electrical pulse and recorded by the built-in counter of the controller 11. This allows for accurate calculation of the number of seeds and improves the accuracy of the counting.
