[0032] Reference Figure 1-6 As shown, this utility model provides a corn planting and seeding device, comprising:

[0033] Insert tube 100, with a feeding port 101 on one side of the upper end and a discharge port 102 on one side of the lower end;

[0034] The lifting and resetting stop bar part 200 includes a resetting lifting rod 210 installed on the insertion tube 100 and a stop bar 220 connected to the lower end of the resetting lifting rod 210. The stop bar 220 blocks the discharge port 102. Pulling up the resetting lifting rod 210 causes the stop bar 220 to move upward, and the discharge port 102 opens.

[0035] This corn planting and seeding device features a pull-to-reset stop bar design. When sowing is needed, pulling up the reset lever moves the stop bar upward, opening the discharge port and allowing the seeds to fall accurately from the outlet. The device has a simple overall structure, low purchase cost, and is easy for operators to use. Sowing can be completed with a simple pulling action, requiring no complicated operating procedures or professional skills, thus reducing labor intensity and improving sowing efficiency.

[0036] As a further preferred embodiment of the above-described embodiment, the insertion tube 100 includes a square tube body 110 and a first handle 120 disposed at the upper end of the square tube body 110. The first handle is convenient for the operator to hold and facilitates the insertion of the insertion tube into the soil. A feeding baffle 130 is provided at the feeding port 101 opened at the upper end of the square tube body 110. The feeding baffle can prevent the seeds from spilling during the feeding process and ensure that the seeds enter the insertion tube smoothly.

[0037] The square tube 110 has a positioning groove 103 on one side where the discharge port 102 is opened, for the installation of the baffle 220.

[0038] The lower end of the square tube 110 is designed as a bevel, which makes it easier to insert into the soil.

[0039] The inlet 101 and outlet 102 are located on opposite sides of the square tube 110.

[0040] As a further preferred embodiment of the above-described embodiment, the reset lifting rod 210 includes a guide post 211 and a positioning sleeve 212 fixedly disposed on the side of the square tube body 110. The guide post 211 is inserted into the positioning sleeve 212, ensuring that the guide post remains stable during up and down movement and does not deviate. A second handle 213 is provided at the upper end of the guide post 211. A retaining ring 214 and a spring 215 are provided on the guide post 211. The spring 215 is fitted onto the guide post 211, with its lower end connected to the retaining ring 214 and its upper end connected to the uppermost positioning sleeve 212. The spring design allows for automatic reset after the guide post is lifted, eliminating the need for manual repositioning of the baffle bar to the position blocking the discharge port, thus improving operational convenience.

[0041] The lower end of the guide post 211 is provided with a threaded end, and a nut 216 is threaded onto the threaded end.

[0042] As a further preferred embodiment of the above-described embodiment, the baffle 220 includes a baffle 221 for blocking the discharge port 102 and a connecting plate 222 disposed on the upper end of the baffle 221. The upper end of the connecting plate 222 is provided with a perforated plate 223. The lower end of the guide post 211 is inserted into the perforated plate 223 and connected to the perforated plate 223 by installing a nut 216 on the threaded end. This connection method makes the connection between the baffle and the reset lifting rod firm and reliable, and at the same time facilitates disassembly and installation.

[0043] During use, the operator holds the first handle, inserts the insertion tube obliquely into the soil, puts the seed into the insertion tube through the inlet 101, then pulls up the second handle, which moves the guide column upward, thereby moving the baffle bar upward to open the discharge port, and the seed falls from the discharge port. After the insertion tube is vertically pulled out of the soil, the second handle is released, and the spring moves the guide column and baffle bar back to their original positions, re-sealing the discharge port, and then the next sowing can be carried out.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
