[0015] The device is equipped with a seeding tray, a sealing plug, a discharge port, a pressure plate, a spring, a pressure rod, a limiting plate, a magnetic block, and a magnetic suction plate. When sowing, the handle is held and the pressure rod is pressed down. The pressure rod moves the seeding tray downward. After the seeding tray moves down, the seeds are discharged through the discharge holes of the discharge plate. When it moves down, the sealing plug disengages from the discharge port, and the seeds enter the seeding tube through the discharge port for sowing. After the pressure plate is released, the spring moves the seeding tray back to its original position, and the sealing plug is reinserted into the discharge port to block the seeds from being discharged. This structure achieves the effect of one press and one discharge, improving the efficiency of manual sowing.

[0016] With a seeding box, a sealing cover, a feed inlet, a handle, and a non-slip sleeve, the seeding box has a compact structure supported by lightweight materials, making it easy for workers to hold. The non-slip sleeve on the handle can improve the stability and comfort of holding the seeding box. When the seeding box has little seed left, the sealing cover can be opened and the seeds can be fed directly into the seeding box from the feed inlet. This structure achieves the functions of compact structure and flexible use.

[0017] With a seeding tube, insert tube, internal threaded groove, and external threaded groove, the worker can insert the insert tube into the seeding groove of the soil while holding the seeding box. The length of the insert tube can be installed according to the height of the worker. During installation, the insert tube of the corresponding height is installed inside the seeding tube. The insert tube and the seeding tube are rotated to achieve a threaded connection and fixation. The appropriate insert tube can avoid the worker bending over to sow, thus improving the efficiency of sowing. Attached Figure Description

The pressure rod 12 is fixedly connected to the left side of the seeding tray 2. A pressure plate 7 is fixedly connected to the top of the pressure rod 12. A limit block 8 is fixedly connected to the outside of the pressure rod 12. A fixing plate 22 is fixedly connected to the left side of the seeding box 1. A spring 9 is fixedly connected to the top of the fixing plate 22. A limit plate 17 is fixedly connected to the top of the seeding tray 2. A magnet block 18 is fixedly connected to the top of the limit plate 17. A limit groove 20 is provided at the bottom of the seeding box 1. A magnetic suction piece 19 is installed inside the limit groove 20.

[0025] Two hundred sets of discharge holes 21 are provided. The sealing plug 4 can be embedded in the discharge port 5 and fits against the inner wall of the discharge port 5. The limiting plate 17 is embedded in the limiting groove 20. The magnet block 18 and the magnetic suction plate 19 are magnetically attached. The spring 9 is sleeved on the outside of the pressure rod 12. The top of the spring 9 is connected to the bottom of the limiting block 8.

[0026] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, the pressure rod 12 drives the seeding disc 2 to move downward. After the seeding disc 2 moves downward, the seeds are discharged through the discharge hole 21 of the discharge plate 3. When it moves downward, the sealing plug 4 is removed from the discharge port 5 and the seeds enter the seeding tube 13 through the discharge port 5 for sowing. After the pressure plate 7 is released, the spring 9 drives the seeding disc 2 to reset. The sealing plug 4 is inserted into the discharge port 5 again to block the seeds from being discharged.

[0027] An anti-slip sleeve 11 is fixedly connected to the inside of the handle 10. Four sets of grooves are evenly arranged inside the anti-slip sleeve 11. The top of the seeding box 1 is provided with a feed inlet 23, and a sealing cover 6 is installed on the feed inlet 23.

[0028] Specifically, such as Figure 1 As shown, the seeding box 1 has a relatively small structure and is supported by lightweight materials, making it easy for workers to hold and handle. When handling, the anti-slip sleeve 11 on the handle 10 can improve the stability and comfort of holding the hand. When the remaining amount of seeds inside the seeding box 1 is low, the sealing cover 6 can be opened to directly feed the seeds into the inside of the seeding box 1 from the feed inlet 23.

[0029] The inner side of the seeding tube 13 is provided with an internal threaded groove 16, and the outer side of the insertion tube 14 is provided with an external threaded groove 15. The top end of the insertion tube 14 is embedded in the inside of the seeding tube 13 in a threaded connection. The bottom end of the discharge port 5 is connected to the inside of the seeding tube 13, and the inside of the seeding tube 13 is connected to the inside of the insertion tube 14.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, during the sowing process, the staff can insert the insertion tube 14 into the sowing trough in the soil. The length of the insertion tube 14 can be installed according to the height of the staff. During installation, the insertion tube 14 of the corresponding height is installed inside the sowing tube 13. The insertion tube 14 and the sowing tube 13 are rotated to achieve a threaded connection and fixation. The appropriate insertion tube 14 can avoid the staff bending over to sow.

[0031] Working principle: When using this invention, tobacco seeds are filled into the sowing box 1. The anti-slip sleeve 11 on the handle 10 improves stability and comfort when holding the device. During sowing, pressing down on the pressure rod 12 moves the sowing disc 2 downwards. After the sowing disc 2 moves downwards, the seeds are discharged through the discharge hole 21 of the discharge plate 3. As it moves downwards, the sealing plug 4 disengages from the discharge port 5, and the seeds enter the sowing tube 13 through the discharge port 5 for sowing. Releasing the pressure plate 7 causes the spring 9 to reset the sowing disc 2, and the sealing plug 4 is reinserted into the discharge port 13. The inside of the feed inlet 5 can be blocked to prevent seeds from being discharged. The insertion tube 14 is inserted into the sowing trough in the soil to achieve sowing. The length of the insertion tube 14 can be installed according to the height requirements of the workers. During installation, the insertion tube 14 of the corresponding height is installed inside the sowing tube 13. The insertion tube 14 and the sowing tube 13 are rotated to achieve a threaded connection and fixation. When the remaining amount of seeds in the sowing box 1 is small, the sealing cover 6 can be opened to directly feed the seeds into the sowing box 1 from the feed inlet 23. This structure achieves the functions of compact structure and flexible use.
