Description

Technical Field

[0001] The present invention relates to the technical field of seeders, and specifically relates to an intelligent monitoring corn seeder. Background Art

[0002] A corn seeder refers to a planting machine that uses corn seeds as the sowing object (also taking into account crops such as soybeans). Usually, the name of the seeder is often prefixed with the name of the crop type, such as corn seeder, grain drill, corn hill-drop planter, cotton planter, forage broadcaster, etc.; During the corn sowing operation process, "full bin" is an important phenomenon that needs attention; the "full bin" mentioned here specifically refers to the bin inside the corn seeder that is specifically used to store seeds. When the seed content in it exceeds one-third, it reaches the full bin state; the main reason for the occurrence of the full bin is that the seeder is continuously affected by bumps and vibrations; this is because when the seeder is operating normally, the seeds rely on their own gravity and the mechanical structure design inside the seeder to flow to the metering device for sowing at a stable speed and in a uniform manner; when sowing on uneven plots, the seeder will inevitably be continuously affected by bumps and vibrations; these bumps and vibrations will disrupt the normal flow order of the seeds inside the seeder, causing the seeds that were originally neatly arranged and waiting to be sown to be randomly piled up inside the seeder due to the vibration; resulting in the seeds being unable to pass through the metering device in a timely and smooth manner, causing the seeds to continuously accumulate inside the seeder, and ultimately leading to the full bin problem; Once the seeder has a full bin problem, it will cause the sowing rate to increase. The seeds that were originally supposed to be evenly sown according to the design will, due to the influence of the full bin, have more seeds than expected sown into the land; that is, the situation where seeds were supposed to be sown at single-grain intervals in the ideal state is broken, and the situation where two seeds appear at close positions simultaneously increases; this situation will affect the subsequent growth space and nutrient acquisition of the corn, and is not conducive to the healthy growth and good development of the corn plants; During the corn sowing operation, when the seeder is in a full bin state, the user can only manually remove the excess seeds inside the seeder and then conduct a comprehensive cleaning of the inside of the seeder; this is because in the full bin state, the seeds will be randomly piled up, resulting in the inside of the seeder being stuck or blocked. At this time, only by thoroughly cleaning the inside of the seeder can potential blockage hazards be eliminated one by one, thereby ensuring the smooth operation of the metering system; however, the structure of the metering system is relatively complex. Without disassembling it, manual cleaning not only takes a long time but also is very difficult to accurately complete, which will undoubtedly affect the progress of the sowing operation and thus reduce the sowing efficiency of the corn sowing operation; In view of this, in order to overcome the above technical problems, the present invention proposes an intelligent monitoring corn seeder, which solves the above technical problems.

[0017] As Figures 1 to 6 shown, an intelligent monitoring corn planter of the present invention includes a frame 1, a seeding mechanism and a detection unit. A ground wheel 11 and a furrow opener 12 are fixedly connected to the lower end of the frame 1; a seeding mechanism is arranged between the furrow opener 12 and the ground wheel 11; the seeding mechanism further includes a storage bin 2; a feed inlet 21 is formed in the side wall of the storage bin 2; a seed metering wheel 22 is rotatably connected in the storage bin 2; a drive motor 13 is installed at the upper end of the frame 1; the drive motor 13 is used to drive the seed metering wheel 22 to rotate; a seed metering tube 23 communicated with the storage bin 2 is fixedly connected to the lower end of the storage bin 2; a discharge port 24 is formed in the lower end of the storage bin 2; a baffle 241 is arranged on the outer ring wall of the storage bin 2; the baffle 241 is rotatably connected to the storage bin 2 through a connecting rod 242; a receiving box 25 is arranged below the discharge port 24; the receiving box 25 is connected to the storage bin 2; a servo motor 26 is fixedly installed on the side wall of the storage bin 2; the detection unit is installed in the storage bin 2; the detection unit is used to detect the stacking height of corn seeds in the storage bin 2.

[0018] As an implementation manner of the present invention, a rotating ring 261 is rotatably connected to the inner wall of the storage bin 2; a scraper 262 is arranged in the storage bin 2; the scraper 262 is fixedly connected to the rotating ring 261; the cross-sectional shape of the scraper 262 is set to be triangular; the rotating ring 261 and the connecting rod 242 are connected through a connecting unit.

[0019] As an implementation manner of the present invention, the connection unit includes a rotating rod 263; the rotating rod 263 is rotatably connected to the connecting rod 242 and the rotating ring 261; a cavity 264 is formed inside the rotating rod 263; a slider 265 is slidably and sealingly connected inside the cavity 264; the slider 265 is connected to the inner wall of the cavity 264 through a support spring 266; an electromagnetic ring 267 is embedded in the inner wall of the cavity 264; connection holes 243 communicating with the cavity 264 are formed inside the connecting rod 242 and the rotating ring 261; a plug rod is slidably connected inside the connection hole 243; the plug rod is connected to the inner wall of the connection hole 243 through a connection spring 244; the plug rod includes a first plug rod 245 and a second plug rod 268; the first plug rod 245 faces the connecting rod 242; the second plug rod 268 faces the rotating ring 261.

[0020] As an implementation manner of the present invention, the detection unit includes a distance sensor 14; the distance sensor 14 is fixedly connected to the inner wall of the storage bin 2.

[0021] As an implementation manner of the present invention, an arc-shaped plate 251 is fixedly connected to the bottom of the material receiving box 25; box doors 252 are rotatably connected to both sides of the material receiving box 25; a blocking rod 253 rotatably connected to the material receiving box 25 is arranged on one side of the box door 252; During operation, during the corn sowing operation, when the seeder is in a full bin state, the user can only manually remove the excess seeds in the seeder and then conduct a comprehensive cleaning of the inside of the seeder; this is because in the full bin state, the seeds will be randomly stacked, resulting in the inside of the seeder being stuck or blocked. At this time, only by thoroughly cleaning the inside of the seeder can potential blockage hazards be eliminated one by one, thereby ensuring the smooth operation of the seed metering system; however, the structure of the seed metering system is relatively complex. Without disassembling it, manual cleaning not only takes a long time but also has a high operation difficulty for the staff, and it is very difficult to accurately complete the cleaning, which will undoubtedly affect the progress of the sowing operation and thus reduce the sowing efficiency of the corn sowing operation.

[0022] In response to this, the present invention is provided with a distance sensor 14, such that when the distance sensor 14 detects that the height of the accumulated seeds in the storage bin 2 reaches one-third of the height inside the storage bin 2, the servo motor 26 starts to drive the baffle 241 at the discharge port 24 to rotate. At this time, the discharge port 24 is opened, enabling the seeds in the storage bin 2 to be discharged into the material receiving box 25 from the discharge port 24; thus, there is no need for the user to manually clean the seeds in the storage bin 2, which not only reduces the cleaning difficulty but also improves the cleaning efficiency; furthermore, it speeds up the progress of the sowing operation and improves the sowing efficiency of the corn sowing operation.

[0023] Before use, the user only needs to install the frame 1 of the present invention at the tail of the farming vehicle, so that the farming vehicle drives the frame 1 to move in the cultivated land. During use, a hopper is installed at the upper end of the frame 1. The hopper and the feed inlet 21 on the side wall of the storage bin 2 can be connected by a hose, so that the corn seeds in the hopper continuously fall into the storage bin 2 through the hose. At this time, the corn seeds are located on one side of the seed metering wheel 22. During the process of the farming vehicle driving the frame 1 to move in the cultivated land, the furrow opener 12 at the lower end of the frame 1 opens a furrow in the cultivated land. At this time, the driving motor 13 is controlled to operate, so that the driving motor 13 drives the seed metering wheel 22 to rotate. As is known from the prior art, the rotating seed metering wheel 22 can dial the corn seeds one by one to the other side of the seed metering wheel 22, so that the seeds falling to the other side of the seed metering wheel 22 can fall from the seed discharge pipe 23, and the falling seeds just fall into the soil furrow opened by the furrow opener 12. At this time, it is the sowing of corn. Subsequently, the ground wheel 11 rolls over the sown soil furrow, so that the soil on the soil furrow slides into the soil furrow under the extrusion of the ground wheel 11, so that the corn seeds in the soil furrow are buried in the soil due to covering.

[0024] During the sowing process, the seeds in the hopper continuously fall into the storage bin 2. Since the distance sensor 14 is installed in the storage bin 2 and is directly above the discharge port 24, when the cumulative height of the seeds in the storage bin 2 continuously increases, the distance sensor 14 detects that the distance between it and the seeds in the storage bin 2 continuously decreases. When the height of the seeds accumulates to one-third of the height of the storage bin 2, at this time, the distance sensor 14 senses that the distance between it and the seeds reaches the preset value, so that the distance sensor 14 transmits an electrical signal to the servo motor 26 and the electromagnetic ring 267. At this time, the electromagnetic ring 267 in the cavity 264 is first energized, so that the electromagnetic ring 267 generates a magnetic adsorption force on the slider 265, so that the slider 265 can squeeze the support spring 266 and move in the direction close to the first insertion rod 245, so that the slider 265 pushes the first insertion rod 245 to squeeze the connecting spring 244 and move in the direction of the connecting rod 242, so that the first insertion rod 245 is inserted into the connection hole 243 on the surface of the connecting rod 242, so that the first insertion rod 245 inserts the connecting rod 242 and the rotating rod 263, and at this time, the servo motor 26 starts to operate, so that the servo motor 26 drives the connecting rod 242 to rotate through the rotating rod 263 connected to it, so that the connecting rod 242 drives the baffle 241 to rotate, so that the baffle 241 blocking the discharge port 24 rotates upward, so that the discharge port 24 blocked by the baffle 241 is continuously opened, so that the seeds accumulated in the storage bin 2 can be discharged from the discharge port 24.

[0025] Since the material receiving box 25 is located below the discharge port 24, the seeds discharged from the discharge port 24 will fall into the material receiving box 25. Since the bottom of the material receiving box 25 is fixedly connected with an arc-shaped plate 251, the middle of the arc-shaped plate 251 is high and both ends are low, and the arc-shaped plate 251 is made of PTFE material, so that the arc-shaped plate 251 has the characteristic of smooth surface, and the corn seeds falling on the arc-shaped plate 251 will flow along the arc-shaped plate 251 towards the two end doors 252 of the material receiving box 25, thus avoiding the accumulation of seeds in the middle part of the material receiving box 25, and further improving the storage capacity of the material receiving box 25. By setting that both the material receiving box 25 and the storage bin 2 are made of transparent acrylic material, the material receiving box 25 and the storage bin 2 made of acrylic material have high transparency, thus providing a good visual effect for the user and facilitating the user to clearly observe the remaining amount of corn seeds in the storage bin 2 and the material receiving box 25. To facilitate the user to observe the conditions of the storage bin 2 and the material receiving box 25, the user directly installs a detection camera on the frame 1 and configures a display and control screen on the farming vehicle, so that the operator can monitor the remaining amount of corn seeds in the storage bin 2 and the material receiving box 25 in real time according to the display and control screen during operation, avoiding faults such as missed seeding, interrupted seeding, and blockage. When the user observes that the corn seeds in the material receiving box 25 need to be recycled due to excessive accumulation, the user only needs to turn the shift lever 253 so that the shift lever 253 no longer blocks the door 252 of the material receiving box 25. At this time, the user only needs to open the door 252, and the corn seeds in the material receiving box 25 can flow out from the ports at the two end doors 252. At this time, the user only needs to use a collection bag to collect the corn seeds in the material receiving box 25.

[0026] When the seeder sows in a cloudy environment, the air will contain a large amount of water vapor. When this warm and humid air encounters the inner wall of the storage bin 2 with a relatively low temperature, the water vapor will be cooled and liquefied, thereby forming water droplets on the inner wall of the storage bin 2. When the seeds fall into the storage bin 2, the corn seeds will come into contact with the water droplets on the inner wall of the storage bin 2, so that the seeds adhere to the inner wall of the storage bin 2 under the action of the surface tension of the liquid, thereby causing the corn seeds adhered to the inner wall of the storage bin 2 to be unable to be effectively discharged from the discharge port 24. To this end, the present invention cooperates with the scraper 262 and the swivel 261. After the servo motor 26 drives the connecting rod 242 to drive the baffle 241 to rotate, the user only needs to control the electromagnetic ring 267 to cut off the power again, so that the electromagnetic ring 267 no longer generates an adsorption force on the slider 265, so that the slider 265 moves away from the No. 1 plug rod 245 to the No. 2 plug rod 268 under the push of the restoring force of the support spring 266, so that the No. 2 plug rod 268 is pushed by the slider 265 to squeeze the connecting spring 244 and insert into the inner wall of the swivel 261 243, so that the rotating rod 263 is connected to the rotating ring 261. At this time, the No. 1 plug rod 245 extends out of the connecting hole 243 of the connecting rod 242 under the push of the restoring force of the connecting spring 244, so that the rotating rod 263 is separated from the connecting rod 242. Since the connecting rod 242 is made of hard rubber material, the wear coefficient of the connecting rod 242 is large, that is, the friction between the connecting rod 242 and the outer wall of the storage bin 2 is large, so that after the connecting rod 242 is separated from the rotating rod 263, the connecting rod 242 will not be driven by the baffle 241 to rotate downward. At this time, the servo motor 26 is running, so that the servo motor 26 can only drive the rotating ring 261 to rotate through the rotating rod 263, so that the rotating ring 261 drives the scraper 262 to rotate, so that the corn seeds in the storage bin 2 are pushed by the scraper 262 and separated from the inner wall of the storage bin 2, thereby realizing that the corn seeds can fall from the discharge port 24 of the storage bin 2, thereby ensuring that the corn seeds can be effectively discharged from the discharge port 24, so that the practicality of the present invention is effectively improved.

[0027] As an embodiment of the present invention, the storage bins 2 are provided with two groups; the storage bins 2 in each group are arranged opposite to each other; a U-shaped plate 15 is fixedly connected to the upper end of the storage bins 2; the U-shaped plate 15 is slidably connected to the frame 1; a screw 16 is rotatably connected to one side of the U-shaped plate 15.

[0028] As an embodiment of the present invention, the storage bin 2 is rotatably connected to a worm gear shaft 17 on the side away from the connecting rod 242; the worm gear shaft 17 is connected to the seed wheel 22; a worm 131 meshing with the worm gear group is provided above the worm gear group; the worm 131 is rotatably connected to the frame 1; the drive motor 13 is installed on one side of the frame 1; and the output shaft of the drive motor 13 is connected to the worm 131.

[0029] As an embodiment of the present invention, the surface of the worm 131 is sleeved with a bellows 18; During operation, the triangular seedling thinning technology is now commonly used for corn sowing. As the name implies, it is to plant corn crops in a triangular layout, with reasonable close planting within the same area. The triangular seedling thinning technology provides good ventilation and light transmission conditions during planting, reduces the bald tip rate of corn, makes each ear of corn plump with grains. In addition, the triangular seedling thinning technology enables corn to effectively utilize photosynthesis, effectively improves the utilization rate of chemical fertilizers, increases drought and waterlogging resistance, ensures the nutrients required by corn during each production period, and provides good conditions for the growth of corn. In order to make the corn sown by the present invention meet the triangular seedling thinning requirement, the present invention is provided with two groups of storage bins 2, and two adjacent storage bins 2 are placed side by side. It should be noted that these two adjacent storage bins 2 are not in a completely aligned state, but are arranged in a staggered manner front and back. When the sowing operation is started, seeds will fall from the seed tubes 23 connected to the two storage bins 2 that are staggered front and back at the same time. The two seeds that fall at the same time are in a diagonal distribution state. As the farming vehicle moves forward steadily, when the seeds fall next time, the positions of the two newly fallen seeds will be in front of the two seeds that fell last time. Moreover, the latter seed of the second fall and the two seeds that fell last time are exactly in a triangular distribution. Through such a carefully designed layout and operation mode, the triangular seedling thinning can be finally achieved smoothly, providing a reasonable space layout and good basic conditions for the growth of subsequent crops.

[0030] When sowing corn, different factors such as soil fertility, air permeability, and the flatness of the terrain will affect the growth of crops. In plots with higher soil fertility, appropriately increasing the sowing spacing can allow the plants to have more sufficient nutrient supply. In plots with lower fertility, appropriately reducing the spacing can make full use of land resources. The present invention is provided with a U-shaped plate 15, so that the storage bin 2 is slidably connected to the lower end of the frame 1 through the U-shaped plate 15, enabling the user to simply slide the U-shaped plate 15 to change the distance between two adjacent staggered storage bins 2. Thus, in plots with higher soil fertility, the user can directly pull two adjacent storage bins 2 away from each other, increasing the sowing spacing between the two storage bins 2. This not only realizes the improvement of the nutrient supply for the plants but also reduces the operation difficulty of the user, thereby improving the sowing efficiency and effectively enhancing the practicality of the present invention.

[0031] When the user needs to increase the distance between two adjacent staggered storage bins 2, the user only needs to rotate the screw rod 16 to rotate away from the rack 1 so that the screw rod 16 does not contact the rack 1. Then the user can push the storage bin 2 to drive the U-shaped plate 15 to slide in contact with the rack 1. After the position of the U-shaped plate 15 is set, the user can directly rotate the screw rod 16 in the opposite direction so that the screw rod 16 spirally rotates in the direction of the rack 1 until the screw rod 16 contacts the rack 1, so that a friction is generated between the screw rod 16 and the rack 1. The screw 16 fixes the U-shaped plate 15 to the frame 1 by generating an extrusion and tightening force. In addition, the present invention sets a transmission connection between the drive motor 13 and the seeding wheel 22 through the worm gear shaft 17 and the worm 131, so that when the storage bin 2 moves through the U-shaped plate 15, the storage bin 2 can drive the worm gear shaft 17 to move synchronously. At this time, it is only necessary to control the drive motor 13 to drive the worm 131 to rotate, so that the worm gear shaft 17 can move along the axis of the worm 131; at the same time, it also ensures stable transmission between the worm gear shaft 17 and the worm 131. In addition, through the worm gear shaft The transmission structure of the worm 17 and the worm 131 enables a driving motor 13 to drive the worm 131 of the two storage bins 2 through a transmission belt, thereby driving the seeding wheels 22 of the two storage bins 2, greatly reducing the number of installed driving motors 13, thereby reducing the production cost of the present invention, and by sleeve-arranging a bellows 18 on the surface of the worm 131, and the worm wheel shaft 17 is located in the bellows 18, the bellows 18 can protect the worm wheel shaft 17 and the worm 131, and prevent the external sand or soil from adhering. On the worm gear shaft 17 and the worm 131, the meshing friction force on the worm gear shaft 17 and the worm 131 is reduced, the friction damage of the worm gear shaft 17 and the worm 131 is reduced, and the service life of the worm gear shaft 17 and the worm 131 is prolonged. In the process of the movement of the worm gear shaft 17, the worm gear shaft 17 will drive the part connected with the bellows 18 to move, so that the bellows 18 is partially compressed, so that the bellows 18 will not block the moving worm gear shaft 17, thereby effectively improving the practicality of the present invention.
