A seed sowing device for a drone

Abstract

This invention provides a material discharge device for a seeding drone, including a drone body with a material storage shell installed below the drone body. The device drives a second motor to rotate a gear and an internal gear ring, causing a semi-circular plate to rotate on the upper surface of a slot. When the semi-circular plate rotates to one side, seeds fall from the discharge hole into the discharge head, thus discharging the seeds. When the semi-circular plate rotates above the discharge hole, it blocks the discharge hole, thereby controlling the discharge speed and improving the uniformity of the discharge. Furthermore, under the action of a spring, a cleaning rod can be ejected from the inner wall of the locking groove, cleaning each discharge hole. When the semi-circular plate rotates to the other side, the discharge hole can continue to discharge seeds, having already been cleaned by the cleaning rod, preventing blockage. This allows the drone to automatically block the discharge holes during flight, avoiding clogging and improving the practicality of the device.

Description

Technical Field

[0001] This utility model belongs to the field of drone seeding technology, and more specifically, it relates to a material discharge device for seeding drones. Background Technology

[0002] Traditional manual sowing methods are not only labor-intensive and inefficient, but also struggle to ensure uniformity and consistency in seeding, making them unsuitable for large-scale agricultural planting. In recent years, the application of drone technology in agriculture has gradually emerged. As a new type of agricultural planting tool, seeding drones offer numerous advantages, including high operational efficiency, strong adaptability, and the ability to achieve precision sowing, bringing about a new revolution in agricultural production.

[0003] Currently, most drones, when sowing seeds, typically place the seeds in a shell, which the drone then carries into the air. Workers control the drone's flight path to scatter the seeds onto the corresponding land. To ensure more even seed distribution, most sowing devices have discharge holes inside the shell, allowing seeds to be scattered and controlling the uniformity and speed of the discharge. However, these discharge holes can become clogged with seeds or impurities over time. Since workers cannot easily clear these holes during drone flight, clogged discharge holes cannot continue to discharge seeds, severely impacting the drone's seeding operation.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a material discharge device for seeding drones, in order to achieve a more practical purpose. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example:

[0024] As attached Figure 1 To be continued Figure 4 As shown:

[0025] This utility model provides a feeding device for a seeding drone, including a drone body 1, a storage shell 2 installed below the drone body 1, a conveying pipe 5 for conveying seeds connected to the bottom of the storage shell 2, an installation shell 8 installed on the outer wall of the conveying pipe 5, and a feeding head 13 for discharging seeds installed at the bottom of the installation shell 8. A slot 15 is opened at the center of the upper surface of the feeding head 13, and multiple discharge holes 14 are opened on one side of the upper surface of the slot 15. When the conveying pipe 5 conveys the seeds from inside the storage shell 2, they can enter the feeding head 13 through the discharge holes 14. A transmission mechanism is provided inside the installation shell 8. The transmission mechanism includes an internal gear ring 9, which is rotatably installed on one side of the inner wall of the installation shell 8. A gear 11 is meshed on one side of the internal gear ring 9. The operation of the gear 11 can drive the internal gear ring 9 to rotate on the inner wall of the installation shell 8.

[0026] In this design, a through groove 12 is formed at the center of the upper surface of the internal gear ring 9, corresponding to the conveying pipe 5. The bottom of the through groove 12 is rotatably connected to the upper surface of the slot 15. A semi-circular plate 16 is installed on one side of the inner wall of the through groove 12. Multiple snap-fit ​​grooves 17 are formed on the lower surface of the semi-circular plate 16. A spring 18 is installed on the top of each snap-fit ​​groove 17, and a cleaning roller 19 is installed at the bottom of each spring 18. The outer sides of the multiple cleaning rollers 19 are adapted to fit the inner wall of the snap-fit ​​groove 17. The rotation of the internal gear ring 9 drives the rotation of the semi-circular plate 16. Since all the discharge holes 14 on the upper surface of the slot 15 are located on the same side, when the semi-circular plate 16 rotates, the discharge holes 14 on the upper surface of the slot 15 rotate. When the circular plate 16 rotates above the discharge hole 14, it can block the discharge hole 14, thereby controlling the discharge speed and improving the uniformity of discharge. Under the action of the spring 18, the cleaning rod 19 can be ejected from the inner wall of the snap-fit ​​groove 17, and the cleaning rod 19 can clean each discharge hole 14. When the semi-circular plate 16 rotates to the other side, the discharge hole 14 can continue to discharge. At this time, the discharge hole 14 has been cleaned by the cleaning rod 19 and will not be blocked. This allows the drone to automatically block the discharge hole 14 during flight, avoiding blockage and improving the practicality of the device.

[0027] The storage shell 2 has an installation base 3 installed on the upper part of its inner wall. The first motor 4 is installed on the inner top of the installation base 3. The output end of the first motor 4 passes through the installation base 3 and is connected to the connecting rod 6. The outer wall of the connecting rod 6 is equipped with a conveying auger 7. The conveying auger 7 is located on one side of the inner wall of the conveying pipe 5. The conveying speed of the clinker is controlled by the conveying auger 7, and the clinker is conveyed in a more uniform and orderly manner.

[0028] A second motor 10 is installed on one side of the lower inner wall of the housing 8. The output end of the second motor 10 is connected to the center of the gear 11 for transmission. The second motor 10 controls the rotation of the gear 11, thereby driving the transmission of related structures.

[0029] Each cleaning roller 19 has an arc-shaped bottom, and the size of each cleaning roller 19 is adapted to the discharge hole 14. The bottom of each cleaning roller 19 abuts against the upper surface of the slot 15. The cleaning roller 19 cleans the debris and blockages on the inner wall of the discharge hole 14. The arc-shaped design makes it easy for the cleaning roller 19 to be carried to the inner wall of the discharge hole 14, so as not to get stuck and to facilitate use.

[0030] The storage shell 2 is equipped with a controller 20 on the front side. The first motor 4 and the second motor 10 are electrically connected to the controller 20 through wires. The controller 20 can control the running speed of the first motor 4 and the second motor 10 or other settings, thereby controlling the speed of the conveying auger 7 or the speed of the semi-circular plate 16, etc., which is convenient for the staff to use.

[0031] The material storage shell 2 has a feed pipe 21 on one side, and a solenoid valve 22 for controlling the addition of seeds is installed on the outside of the feed pipe 21.

[0032] The working principle of this embodiment is as follows: First, seeds are added through the feed pipe 21 on one side of the storage shell 2. The solenoid valve 22 on the outside can control the seed addition operation to ensure that there are enough seeds in the storage shell 2 for the drone to sow. The seeds in the storage shell 2 are driven by the first motor 4 to drive the connecting rod 6 to rotate, which in turn drives the conveying auger 7 to run. The conveying auger 7 is located on one side of the inner wall of the conveying pipe 5, and it conveys the seeds in the storage shell 2 evenly and orderly down the conveying pipe 5 so that the seeds enter the slot 15 of the discharge head 13. The second motor 10 drives the gear 11 to rotate. The gear 11 meshes with the inner gear ring 9, so that the inner gear ring 9 rotates on the inner wall of the mounting shell 8. The bottom of the through groove 12 on the inner gear ring 9 is rotatably connected to the upper surface of the slot 15. The semi-circular plate 16 on one side of the inner wall of the through groove 12 rotates with the inner gear ring 9.

[0033] Secondly, when the semicircular plate 16 rotates above the discharge hole 14, it blocks the discharge hole 14 to control the discharge speed and improve the uniformity of discharge. At the same time, the spring 18 in the locking groove 17 extends and retracts, causing the cleaning roller 19 to pop out or retract. When the semicircular plate 16 rotates so that the cleaning roller 19 is aligned with the discharge hole 14, under the elastic force of the spring 18, the cleaning roller 19 pops out and extends into the discharge hole 14 to clean the debris and blockages in the hole. The arc-shaped design of the bottom of the cleaning roller 19 makes it easy to detach from the inner wall of the discharge hole 14. To prevent jamming and ensure smooth cleaning, after the semicircular plate 16 rotates to the other side, the discharge hole 14 resumes discharge. At this time, the discharge hole 14 has been cleaned by the cleaning roller 19 to avoid blockage and ensure smooth material discharge during drone flight. The controller 20 on the front side of the storage shell 2 is electrically connected to the first motor 4 and the second motor 10 through wires. It can adjust the motor running speed, control the rotation speed of the conveying auger 7 and the semicircular plate 16, and thus control the seed conveying speed and the cleaning frequency of the discharge hole 14 to achieve precise material discharge.

Many modifications and variations will be apparent to those skilled in the art.
