Description

Technical Field

[0001] This utility model relates to the field of seeding machinery technology, specifically to an anti-clogging seeding device. Background Technology

[0002] In traditional agricultural production, manual sowing methods such as broadcasting and row sowing are inefficient, result in uneven seed distribution, and are labor-intensive, making it difficult to meet the demands of modern large-scale and precision agriculture. With the development of agricultural mechanization, mechanical sowing devices, such as grain row seeders and corn planters, have become widely used, significantly improving sowing efficiency. However, in mechanical sowing, differences in the shape, size, and surface characteristics of different seeds can lead to blockages in parts such as the seed delivery tube. During the sowing process, impurities such as clay particles, stones, weeds, and straw fragments from the soil can also enter the sowing device, mixing with the seeds and causing further blockages. Furthermore, blockages in the sowing device can lead to double-seeding or missed sowing. Double-seeding results in seed waste and insufficient growing space for crops, while missed sowing wastes land resources and creates gaps in the rows, affecting crop growth and yield while increasing labor and time costs. Therefore, there is an urgent need for a device that can effectively solve these problems to ensure smooth sowing without blockages. Utility Model Content

The nozzle is mounted on the seed metering tube and communicates with the air pump. The nozzle has an air jet hole located inside the seed metering tube. The pulsed air source generated by the air pump enters the seed metering tube through the nozzle and can push the seeds downwards.

[0008] For example, at least one embodiment of this utility model provides an anti-blocking seeding device, which further includes:

[0009] A vibration device is installed on the seed metering pipe, and the vibration device can drive the seed metering pipe to vibrate.

[0010] For example, at least one embodiment of this utility model provides an anti-clogging seeding device, wherein the seeding tube is divided into a first section and a second section, the first section is vertically arranged, the second section is inclinedly arranged on the first section, and the vibration device is located at the connection between the first section and the second section.

[0011] For example, at least one embodiment of this utility model provides an anti-clogging seeding device, wherein the nozzle is located on the first section and penetrates the side wall of the first section, and the air jet hole is inclined downward.

[0012] For example, at least one embodiment of this utility model provides an anti-clogging seeding device in which the central axis of the air jet hole forms an angle of 15° with the plane containing the side wall of the first segment.

[0013] For example, at least one embodiment of this utility model provides an anti-blocking seeding device, wherein the seed discharging device further includes:

[0014] An outer casing is disposed on the mounting bracket, the outer casing having a receiving cavity that communicates with the seed metering tube and is located above the seed metering tube;

[0015] A storage hopper is disposed on the outer shell, the storage hopper is connected to the receiving cavity, and the storage hopper is used to store seeds;

[0016] A wheel is rotatably disposed within the receiving cavity. The wheel has several grooves that can receive seeds from the storage hopper and convey them to the seed dispensing pipe.

[0025] The beneficial effects of the embodiments of this utility model are as follows:

[0026] In this invention, the seed metering device delivers seeds to the ground via a seed metering tube, providing a basic channel for sowing. The air pump of the air blowing device generates a pulsed air source, which enters the seed metering tube through the nozzle's air jet. This pulsed air source applies a periodic force to the seeds and impurities within the seed metering tube. This periodic force breaks up any blockages that may form between the seeds and impurities, allowing seeds that might otherwise stagnate to continue moving downwards, reducing the probability of blockage. When seeds are obstructed from moving due to mutual compression or friction against the tube wall, the impact force of the pulsed air source can push the seeds to change position, preventing the formation of stable blockages. For soil impurities entering the seed metering tube, the pulsed air source can separate them from the seeds and push the impurities downwards along with the seeds, preventing impurities from accumulating and causing blockages. Because blockages are reduced, seeds can reach the ground through the seed metering tube according to the preset pattern of the seed metering device, reducing the occurrence of double-seeding or missed sowing. Seed distribution is more in line with expectations, avoiding seed waste and insufficient growing space caused by reseeding, as well as land resource waste and missing seedlings caused by missed sowing, thereby reducing labor and time costs and ensuring crop growth and yield.

[0042] like Figures 1-7 The diagram illustrates an anti-clogging seeding device according to an embodiment of the present invention. It includes a mounting frame 1, a seed metering device 2 mounted on the mounting frame 1, and a seed metering pipe 201 for conveying seeds to the ground. An air blowing device 3 includes an air pump 301 and a nozzle 302. The air pump 301, mounted on the mounting frame 1, generates a pulsed air source. The nozzle 302 is mounted on the seed metering pipe 201 and communicates with the air pump 301. The nozzle 302 has an air jet hole 3021 located inside the seed metering pipe 201. One end of the seed metering pipe 201 is connected to the seed output end of the seed metering device 2, and the other end extends above the ground. The nozzle 302 penetrates the wall of the seed metering pipe 201 radially, and the opening of the air jet hole 3021 faces the seed flow path within the seed metering pipe 201. Air pump 301 is connected to nozzle 302 via a pipeline. One end of the pipeline is connected to the air outlet of air pump 301, and the other end is connected to the air inlet of nozzle 302. During sowing, seed metering device 2 delivers seeds into seed metering pipe 201, where they move towards the ground. Simultaneously, air pump 301 starts, generating a pulsed air source that is delivered to nozzle 302 via the pipeline and enters seed metering pipe 201 through jet nozzle 3021. The pulsed air source acts on the seeds and any impurities present in seed metering pipe 201, propelling the seeds downwards.

[0043] Specifically, the seed metering device 2 delivers seeds to the ground via the seed metering pipe 201, providing a basic channel for sowing. The air pump 301 of the air blowing device 3 generates a pulsed air source, which enters the seed metering pipe 201 through the jet nozzle 3021 of the nozzle 302. This pulsed air source applies a periodic force to the seeds and impurities within the seed metering pipe 201. This periodic force breaks up any blockages that may form within the seed metering pipe 201, allowing seeds that might otherwise stagnate to continue moving downwards, reducing the probability of blockage. When seeds are obstructed from moving within the seed metering pipe 201 due to mutual compression or friction with the pipe wall, the impact force of the pulsed air source can push the seeds to change position, preventing the formation of stable blockages. For soil impurities entering the seed metering pipe 201, the pulsed air source can separate them from the seeds and push the impurities downwards along with the seeds, preventing impurities from accumulating and causing blockages within the seed metering pipe 201. Because blockages are reduced, seeds can reach the ground through the seed metering pipe 201 according to the set pattern of the seed metering device 2, reducing the occurrence of double-seeding or missed sowing. Seed distribution is more in line with expectations, avoiding seed waste and insufficient growing space caused by reseeding, as well as land resource waste and missing seedlings caused by missed sowing, thereby reducing labor and time costs and ensuring crop growth and yield.

[0044] like Figures 1-6 As shown, the vibration device 4 is installed on the seed metering pipe 201, and the vibration device 4 can drive the seed metering pipe 201 to vibrate. The seed metering pipe 201 is divided into a first section 2011 and a second section 2012. The first section 2011 is set vertically, and the second section 2012 is set inclinedly on the first section 2011. The vibration device 4 is located at the connection between the first section 2011 and the second section 2012. The nozzle 302 is located on the first section 2011 and penetrates the side wall of the first section 2011. The air jet hole 3021 is set downwardly inclined, and the angle between the central axis of the air jet hole 3021 and the plane containing the side wall of the first section 2011 is 15°.

[0045] The vibration device 4 is installed at the connection between the first section 2011 and the second section 2012 of the seed metering tube 201. The vibration causes the seeds and impurities inside the seed metering tube 201 to shift, and in conjunction with the pulse air source of the blowing device 3, further breaks up any potential blockages. The seed metering tube 201 is divided into a vertical first section 2011 and an inclined second section 2012, allowing the seeds to move along the paths of the two sections under the combined action of gravity, the thrust of the pulse air source, and vibration, reducing stagnation at bends. The nozzle 302 is located in the first section 2011, and the air jet 3021 is inclined downwards, forming a 15° angle with the side wall of the first section 2011, allowing the pulse air source to act more precisely on the flow direction of the seeds, enhancing the pushing effect.

[0046] like Figures 4-7As shown, the seed metering device 2 also includes a housing 202, a storage hopper 203, and a wheel 204. The housing 202 is mounted on the mounting frame 1 and has a receiving cavity 2021 inside. The receiving cavity 2021 communicates with the seed metering pipe 201 and is located above the seed metering pipe 201. The storage hopper 203 is mounted on the housing 202 and communicates with the receiving cavity 2021. The storage hopper 203 is used to store seeds. The wheel 204 is rotatably mounted inside the receiving cavity 2021 and has several grooves 2041 on it. The grooves 2041 can receive the seeds in the storage hopper 203 and convey them to the seed metering pipe 201. The wheel 204 of the seed metering device 2 quantitatively receives seeds through the grooves 2041, realizing the orderly delivery of seeds and keeping the amount of seeds entering the seed metering pipe 201 stable, avoiding blockage caused by excessive seeds. The hopper 203 provides storage space for seeds, and the receiving cavity 2021 of the outer shell 202 provides a closed environment for the rotation of the wheel 204 and the transfer of seeds, reducing the entry of impurities into the seed discharge tube 201 from above.

[0047] like Figures 1-2 As shown, the furrowing tray 5 is mounted on the mounting frame 1 at the front end of the seed metering device 2 in the direction of travel. The furrowing tray 5 is used to create furrows in the ground to accommodate seeds. The covering plate 6 is mounted on the mounting frame 1 at the rear end of the seed metering device 2 in the direction of travel. The covering plate 6 is used to cover the seeds with soil. The compaction wheel 7 is mounted on the mounting frame 1 at the rear end of the covering plate 6 in the direction of travel. The compaction wheel 7 is used to compact the soil covered by the covering plate 6. The furrowing tray 5 creates furrows before seed metering, providing a predetermined space for the seeds and making the seed landing point more concentrated. The covering plate 6 covers the soil after seed metering to prevent the seeds from being exposed. The compaction wheel 7 compacts the soil, ensuring close contact between the seeds and the soil, which is beneficial for seed germination.

[0048] Specifically, during sowing, the seeds in the storage hopper 203 enter the receiving cavity 2021. The wheel 204 rotates, and the groove 2041 receives the seeds and rotates with the wheel 204 to the inlet of the seed dispensing tube 201. The seeds fall into the first section 2011 of the seed dispensing tube 201. The groove 2041 can hold the corresponding number of seeds required for sowing. For example, when sowing one seed, the groove 2041 can only hold one seed; when sowing two seeds, the groove 2041 can only hold two seeds, avoiding double sowing. The wheel 204 is detachably installed in the receiving cavity 2021. When sowing different numbers of seeds, the wheel 204 can be replaced, improving the compatibility of the device. Furthermore, a baffle is installed in the receiving cavity 2021 to prevent other seeds in the receiving cavity 2021 from entering the seed dispensing tube 201. The vibration device 4 is activated, causing the connection between the first section 2011 and the second section 2012 to vibrate, causing the seeds and impurities in the seed dispensing tube 201 to vibrate. The pulsed air source generated by the air pump 301 enters the first section 2011 through the jet hole 3021 of the nozzle 302, propelling the seeds to the second section 2012. After being discharged through the second section 2012, the seeds fall into the furrows opened by the furrowing plate 5. Subsequently, the soil covering plate 6 covers the seeds with soil, and the compaction wheel 7 compacts the covered soil.

[0049] like Figures 1-3 As shown, the cleaning device 8 has a water tank 801 and a cleaning pipe 802. The water tank 801 is mounted on the mounting frame 1. The water tank 801 can also be mounted on the equipment of a traction seeding device, such as a tractor. The cleaning pipe 802 is connected to the water tank 801 and penetrates the outer wall of the first section 2011. The cleaning pipe 802 can transport the cleaning solution in the water tank 801 into the seed metering pipe 201. The cleaning pipe 802 of the cleaning device 8 can deliver cleaning solution into the seed metering pipe 201 to clean the seed metering pipe 201 during non-sowing periods, reducing the impact of residual impurities on subsequent sowing.
