Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-4 , an embodiment provided by the present utility model:

[0031] A rice seedling raising and sowing device, which includes:

[0032] A load-carrying vehicle body 1, on which an installation frame 2 is fixed. Inside the installation frame 2, a horizontal threaded rod 3 is fixedly installed. A positioning clip 4 is installed on the horizontal threaded rod 3. The positioning clip 4 is fixedly installed on the outer wall of the storage hopper 5. The front view shape of the positioning clip 4 is "C"-shaped. The positioning clip 4 is snap-connected to the horizontal threaded rod 3. Both the horizontal threaded rod 3 and the positioning clip 4 are symmetrically distributed about the center of the storage hopper 5. The above structural design enables the storage hopper 5 to be quickly connected to the horizontal threaded rod 3 through the positioning clip 4, and the horizontal threaded rod 3 stably supports the storage hopper 5. A locking nut 6 is installed on the horizontal threaded rod 3. The locking nut 6 is horizontally symmetrically distributed about the center of the positioning clip 4. The above structural design can strengthen the positioning effect on the positioning clip 4 and the storage hopper 5 by squeezing the positioning clip 4. The storage hoppers 5 are horizontally equidistantly distributed inside the installation frame 2. The center of the installation frame 2 and the center of the storage hopper 5 are on the same vertical plane. The above structural design ensures that the storage hopper 5 can be conveniently disassembled and installed, and the storage hopper 5 cooperates with the bottom structure to achieve stable equidistant sowing.

[0033] A corrugated pipe 9, the top end of the corrugated pipe 9 is fixedly connected to the bottom end of the storage hopper 5, and the bottom end of the corrugated pipe 9 is fixedly connected to one side of the top surface of the transfer hopper 10. The outer wall of the transfer hopper 10 fits against the inner wall of the positioning window 11. The positioning window 11 is opened on the base plate 8. An electric telescopic rod 7 is fixed to the edge of the top surface of the base plate 8. The top end of the electric telescopic rod 7 is fixedly connected to the bottom surface of the installation frame 2.

[0034] Side magnetic blocks 12 are fixedly installed on the top of the outer wall of the transfer hopper 10. The bottom surface of the side magnetic blocks 12 fits against the top surface of the magnetic strip 13. The magnetic strip 13 is fixedly installed on the top surface of the base plate 8 at the top edge of the positioning window 11. A motor 14 is fixed to the top of the transfer hopper 10. A feeding auger rod 15 is installed on the output shaft at the bottom end of the motor 14. The feeding auger rod 15 penetrates through the bottom pipe of the transfer hopper 10.

[0035] In one embodiment, the vertical plane where the center of the corrugated pipe 9 is located is parallel to the vertical plane where the center of the transfer hopper 10 is located. The center of the transfer hopper 10 and the center of the storage hopper 5 are on the same vertical plane. The above structural design can avoid interference between the corrugated pipe 9 and the motor 14, and ensure that the rice seeds can smoothly fall into the transfer hopper 10 through the corrugated pipe 9.

[0036] In one preferred embodiment, the side walls of the transfer hopper 10 and the side walls of the positioning window 11 are both inclined. The front view cross-sectional shape of the transfer hopper 10 is an inverted isosceles triangle. The above structural design enables the transfer hopper 10 to quickly fit and position with the positioning window 11 and will not fall off.

[0037] In one embodiment, both the side magnet blocks 12 and the magnet bars 13 are neodymium magnets. The side magnet blocks 12 are symmetrically distributed about the center of the transfer hopper 10, and the magnet bars 13 are symmetrically distributed about the center of the positioning window 11. The above structural design enables a strong magnetic force between the side magnet blocks 12 and the magnet bars 13, capable of stably positioning the transfer hopper 10.

[0038] In one preferred embodiment, the centers of the motor 14, the feeding auger rod 15, and the transfer hopper 10 are on the same vertical line. The bottom end of the feeding auger rod 15 is set as a cone. The above structural design enables the motor 14 to drive the feeding auger rod 15 to rotate and output the rice seeds in the transfer hopper 10 downward, and stably feed them into the holes opened by the rotation at the bottom end of the feeding auger rod 15.

[0039] The working principle of the present utility model is as follows: When using this device, as Figure 2 and Figure 3 shown, arrange the storage hoppers 5 at a preset interval, engage the positioning cards 4 on both sides with the horizontal threaded rods 3, rotate the symmetrically distributed locking nuts 6 to squeeze and lock the positioning cards 4. Then, vertically insert the transfer hopper 10 into the positioning window 11, and the side magnet blocks 12 and the magnet bars 13 are stably adsorbed to complete the debugging and installation;

[0040] Then, move the entire device into the paddy field. Put rice seeds into the storage hopper 5. The rice seeds enter the transfer hopper 10 through the corrugated pipe 9. Control the load-carrying vehicle body 1 with a traveling mechanism to move forward to a suitable position, control the load-carrying vehicle body 1 to stop, control the electric telescopic rod 7 to extend. The electric telescopic rod 7 pushes the substrate 8 to move vertically downward. The substrate 8 drives the transfer hopper 10 and the feeding auger rod 15 to move vertically downward and stretch the corrugated pipe 9 until the bottom end of the feeding auger rod 15 penetrates into the soil to a sufficient depth. Control the electric telescopic rod 7 to stop working, start the motor 14. The motor 14 drives the feeding auger rod 15 to rotate stably. The feeding auger rod 15 rotates and sends the rice seeds in the transfer hopper 10 downward, and feeds the rice seeds into the holes dug by the feeding auger rod 15. The amount of the downward-sent rice seeds is determined by the rotation time of the feeding auger rod 15;

[0041] After a single seeding is completed, control the motor 14 to stop working, control the electric telescopic rod 7 to shorten, pull the substrate 8 to drive the feeding auger rod 15 to move upward and reset to separate from the soil. Again, control the load-carrying vehicle body 1 to move forward a preset distance, and repeat the above operations to perform seeding again.

[0042] The above are only the embodiments of the present utility model, and common knowledge such as the specific structures and characteristics known in the solutions is not described in detail herein. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be construed as limiting the claimed rights involved.
