Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a seed clearing device of a seeding machine. Background Art

[0002] With the rapid development of modern agricultural technology, as an important equipment in agricultural production, the sowing efficiency and sowing quality of the seeder have an increasingly significant impact on agricultural production. As the core component of the seeder, the performance of the seeder seed meter directly determines the overall performance of the seeder. However, in actual use, due to the influence of various factors such as seed quality, seed meter structure design and working environment, the seeder seed meter often re-seed, that is, sowing multiple times at the same location, which not only wastes seeds, but also may cause uneven crop growth, affecting yield and quality.

[0003] Most of the existing seeding machine seed clearing devices use mechanical or airflow cleaning methods. Mechanical seed clearing devices have complex structures, are easy to wear, and have high maintenance costs; although airflow seed clearing devices have simple structures, they have high requirements for airflow control. Most of the existing pneumatic seed clearing devices use two rows of air jets to clean seeds, and the seed cleaning effect is not ideal. Either too much seed is cleaned, resulting in a high rate of missed seeding, or too little seed is cleaned, resulting in a high rate of reseeding.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to develop a new type of seed clearing device for a seeder to improve the sowing quality and efficiency of the seeder, reduce the reseeding rate, and reduce seed waste, thereby promoting the sustainable development of modern agriculture.

[0008] As a further description of the above technical solution: the number of the air outlet rods is two, and the multiple jet ports fixedly installed on the outer walls of the two air outlet rods are arranged relatively to each other. By setting the number of the air outlet rods to be two and the multiple jet ports fixedly installed on the outer walls of the two air outlet rods to be arranged relatively to each other, after the device is ventilated into the air outlet rods through the cylinder, the two air outlet rods can spray air to both sides at the same time.

[0009] As a further description of the above technical solution: a square groove is opened on the inner wall of the loading plate, the connecting block is located in the square groove, and the front end of the connecting block is fixedly connected to the rear end of the mounting rod. By setting the square groove and arranging the connecting block in the square groove, the threaded sleeve fixedly connected to the connecting block is limited during the rotation of the screw rod and can move up and down.

[0010] As a further description of the above technical solution: a limit rod is fixedly installed inside the mounting rod, the mounting block is fixedly installed on both sides of the limit rod, and one side of the limit rod is fixedly connected to a rotating rod. By setting the limit rod and setting the mounting block fixedly installed on both sides of the limit rod, the mounting block and the parts installed on the mounting block can be fixed.

[0011] As a further description of the above technical solution: the number of the moving blocks is two, which are symmetrically distributed on the outer wall of the bidirectional screw in the initial state. The moving block is threadedly connected to the outer wall of the bidirectional screw and can also be slidably mounted on the outer wall of the limit rod. By setting the moving block to be threadedly connected to the outer wall of the moving block and can also be slidably mounted on the outer wall of the limit rod, the moving block is limited.

By setting the number of the gas outlet rods 6 to be two and setting the plurality of air jets 7 fixedly installed on the outer walls of the two gas outlet rods 6 to be arranged relatively to each other, after the device is ventilated to the gas outlet rods 6 through the cylinder 4, the two gas outlet rods 6 can spray air to both sides at the same time.

[0023] In specific implementation, when the seed metering device 2 is in operation, the user can start the cylinder 4. After starting the cylinder 4, the cylinder 4 will inflate the two air outlet rods 6, so that the multiple air jets 7 installed on the air outlet rods 6 will start to spray air. At this time, the plant seeds brought up by the seed metering device 2 will be blown by the air jets 7 installed on the two air outlet rods 6, and those seeds that are not adsorbed by the seed metering device 2 will be blown off by the two air jets 7 to complete the seed cleaning process. In addition, during the seed cleaning process, since the air jets 7 are left-right opposed seed cleaning types, the seed cleaning effect is greatly improved and the machine reseeding rate is significantly reduced.

[0024] By setting two air outlet rods 6, and fixing a plurality of air jets 7 on the outer wall of the air outlet rods 6, and finally setting the two air jets 7 to be opposite to each other on the left and right in the initial state, after the cylinder 4 is started, the plurality of air jets 7 will perform left-right opposite seed cleaning on the seeds on the surface of the loading plate 1, so that the seed cleaning effect is greatly improved, the machine reseeding rate is significantly reduced, and the machine adaptability is significantly enhanced.

[0025] Embodiment 2

[0026] Reference Figure 1-4 The utility model provides a seed clearing device for a seeding machine: a motor 13 is fixedly installed on the rear side of a loading plate 1, a rotatable threaded sleeve 15 is connected above the motor 13, a connecting block 16 is fixedly connected to the outer wall of the threaded sleeve 15, a mounting block 9 is arranged on the front side of the loading plate 1, a rotatable bidirectional screw rod 10 is arranged on one side of the mounting block 9, a moving block 17 is threadedly connected to the outer wall of the bidirectional screw rod 10, an air outlet rod 6 is fixedly installed on the front side of the moving block 17, a square groove 12 is opened on the inner wall of the loading plate 1, the connecting block 16 is in the square groove 12, the front end of the connecting block 16 is fixedly connected to the rear end of the mounting rod 5, by setting the square groove 12 and setting the connecting block 16 in the square groove 12, the threaded sleeve 15 fixedly connected to the connecting block 16 is arranged on the screw rod 1 During the rotation, the mounting rod 5 is limited and can move up and down. The limiting rod 11 is fixedly installed inside the mounting rod 5, and the mounting block 9 is fixedly installed on both sides of the limiting rod 11. One side of the limiting rod 11 is fixedly connected with the rotating rod 3. By setting the limiting rod 11 and setting the mounting block 9 to be fixedly installed on both sides of the limiting rod 11, the mounting block 9 and the parts installed on the mounting block 9 can be fixed. The number of the moving blocks 17 is two and they are symmetrically distributed on the outer wall of the bidirectional screw rod 10 in the initial state. The moving block 17 is threadedly connected to the outer wall of the bidirectional screw rod 10 and can also be slidably sleeved on the outer wall of the limiting rod 11. By setting the moving block 17 to be threadedly connected to the outer wall of the moving block 17 and can also be slidably sleeved on the outer wall of the limiting rod 11, the moving block 17 is limited.

[0027] In specific implementation, on the basis of the above-mentioned embodiment 1, during the process of seed cleaning of the device, due to the different sizes and shapes of seeds, the two fixed air outlet rods 6 cannot always maintain a good seed cleaning effect. At this time, the motor 13 can be started. After starting, the motor 13 will drive the screw rod 14 to rotate. After the screw rod 14 rotates, the threaded sleeve 15 threadedly connected to the outer wall of the screw rod 14 will be driven to rise, and one side of the threaded sleeve 15 is fixedly connected to the connecting block 16, and the other side of the connecting block 16 is fixedly connected to the mounting rod 5. Therefore, after the threaded sleeve 15 rises, the mounting rod 5 and multiple parts installed on the mounting rod 5 will also rise, and the two air outlet rods 6 and multiple air jets 7 are no exception. At this time, the air jets 7 are away from the seed metering device 2, so that the device can adapt to seeds with large mass that cannot be firmly adsorbed by the seed metering device 2.

[0028] In addition, the user can also manually rotate the rotating rod 3, which will drive the bidirectional screw rod 10 to rotate after rotation, and the two moving blocks 17 threadedly connected to the outer wall of the bidirectional screw rod 10 will move toward or relative to each other, so that the air outlet rod 6 connected to the front end of the moving block 17 approaches or moves away from each other, thereby increasing or decreasing the blowing force on the seeds adsorbed on the surface of the seed metering device 2.

[0029] By setting a screw rod 14 and a threaded sleeve 15, and setting two moving blocks 17 threadedly connected to the outer wall of the bidirectional screw rod 10, the position of the air outlet rod 6 in the device can be adjusted, so that the user can change the blowing force of the air jet 7 on the seeds in a relatively simple way, thereby increasing the application range of the device.

[0030] Working principle:

[0031] When using the utility model, when the seed metering device 2 is in operation, the user can start the cylinder 4. After starting the cylinder 4, the cylinder 4 will inflate air into the two air outlet rods 6, so that the multiple air jets 7 installed on the air outlet rods 6 start to spray air. At this time, the plant seeds brought up by the seed metering device 2 will be blown by the air jets 7 installed on the two air outlet rods 6, and those seeds that are not adsorbed by the seed metering device 2 will be blown off by the two air jets 7 to complete the seed cleaning process. In addition, during the seed cleaning process, since the air jets 7 are left-right opposed seed cleaning types, the seed cleaning effect is greatly improved and the machine reseeding rate is significantly reduced.

[0032] By setting two air outlet rods 6, and fixing a plurality of air jets 7 on the outer wall of the air outlet rods 6, and finally setting the two air jets 7 to be opposite to each other on the left and right in the initial state, after the cylinder 4 is started, the plurality of air jets 7 will perform left-right opposite seed cleaning on the seeds on the surface of the loading plate 1, so that the seed cleaning effect is greatly improved, the machine reseeding rate is significantly reduced, and the machine adaptability is significantly enhanced.

[0033] During the seed cleaning process of the device, due to the different sizes and shapes of seeds, the fixed two air outlet rods 6 cannot always maintain a good seed cleaning effect. At this time, the motor 13 can be started. After starting, the motor 13 will drive the screw rod 14 to rotate. After the screw rod 14 rotates, the threaded sleeve 15 threadedly connected to the outer wall of the screw rod 14 will be driven to rise, and one side of the threaded sleeve 15 is fixedly connected to the connecting block 16, and the other side of the connecting block 16 is fixedly connected to the mounting rod 5. Therefore, after the threaded sleeve 15 rises, the mounting rod 5 and multiple parts installed on the mounting rod 5 will also rise, and the two air outlet rods 6 and multiple air jets 7 are no exception. At this time, the air jets 7 are away from the seed metering device 2, so that the device can adapt to seeds with large mass that cannot be firmly adsorbed by the seed metering device 2.

[0034] In addition, the user can also manually rotate the rotating rod 3, which will drive the bidirectional screw rod 10 to rotate after rotation, and the two moving blocks 17 threadedly connected to the outer wall of the bidirectional screw rod 10 will move toward or relative to each other, so that the air outlet rod 6 connected to the front end of the moving block 17 approaches or moves away from each other, thereby increasing or decreasing the blowing force on the seeds adsorbed on the surface of the seed metering device 2.

[0035] By setting a screw rod 14 and a threaded sleeve 15, and setting two moving blocks 17 threadedly connected to the outer wall of the bidirectional screw rod 10, the position of the air outlet rod 6 in the device can be adjusted, so that the user can change the blowing force of the air jet 7 on the seeds in a relatively simple way, thereby increasing the application range of the device.
