[0085] Chassis structure;

[0086] The movable wheel structure is mounted on the frame structure.

[0087] The feed bin structure contains corn seeds and is mounted through the frame structure, with one end of the feed bin extending downwards.

[0088] One side of the middle section of the moving wheel structure is located inside the material box structure;

[0089] Multiple agitators are mounted on the moving wheel structure and are located inside the material box structure.

When the multiple agitators rotate synchronously, they can agitate the corn seeds in the hopper structure to assist in the discharge and unloading of the corn seeds.

[0094] Since each Z-shaped discharge pipe 13 can rotate on the material box structure, each Z-shaped discharge pipe 13 can be adjusted left and right according to the actual use. Multiple Z-shaped discharge pipes 13 can be closed or opened on the material box structure, so that the corn planting device can easily adjust the planting density when planting corn seeds.

[0095] like Figure 1-3 This demonstrates the use of multiple Z-shaped discharge pipes 13 in the retracted state of the corn planting device, such as... Figure 5-6 The image shows the use of multiple Z-shaped discharge pipes 13 in the corn planting device in the open state.

[0096] Meanwhile, when planting corn seeds, the corn planting device can simultaneously cultivate the soil through the tillage component to facilitate the planting of corn seeds.

[0106] Example 3

[0107] like Figure 1-15 As shown, improvements are made based on Example 2:

[0108] Furthermore, the feed box structure includes a seed feed box 7, the top of which is open, and the corn seeds are placed in the inner cavity of the seed feed box 7. The seed feed box 7 is inserted into the fixed frame 5, and the seed feed box 7 and the fixed frame 5 are fastened together by multiple bolts.

[0110] Multiple discharge holes 701 are equidistantly provided at the center of the bottom of the inner cavity of the seed box 7. Each discharge hole 701 is connected to a discharge pipe 702 on the outside. Each discharge pipe 702 is fixedly connected to the bottom of the seed box 7.

[0111] Each discharge pipe 702 is used for discharging and unloading materials;

[0112] The lower part of the opposite side walls of the seed feed box 7 is provided with insertion holes 703;

[0113] The two insertion holes 703 correspond to the shaft holes of the two bearing seats 2, and the two insertion holes 703 and the shaft holes of the two bearing seats 2 can form an insertion installation channel after they overlap.

[0120] Both sides of the bottom of the inner cavity of the seed hopper 7 are fixedly installed with wedge-shaped guide bases 11. The upper surface of each wedge-shaped guide base 11 has a guide slope 1101. Both wedge-shaped guide bases 11 are used for guiding materials. Furthermore, the guide slopes 1101 on the two wedge-shaped guide bases 11 can allow the corn seeds in the seed hopper 7 to flow to the discharge pipe 702.

The position of each agitator impeller 12 corresponds one-to-one with each discharge hole 701. The agitator impeller 12 is the preferred form of the agitator. Since the position of each agitator impeller 12 corresponds one-to-one with each discharge hole 701, when each agitator impeller 12 rotates synchronously, the discharge and discharge speed of corn seeds at the corresponding discharge pipe 702 can be accelerated.

[0124] Example 5

[0126] Furthermore, one end of each Z-shaped discharge pipe 13 is inserted into the corresponding discharge pipe 702, and each Z-shaped discharge pipe 13 can rotate around the discharge pipe 702 as an axis, thereby allowing each Z-shaped discharge pipe 13 to adjust its operating angle.

[0127] Furthermore, a U-shaped bottom bracket 14 is fixedly installed at the bottom of the chassis 1 at the corresponding multiple Z-shaped discharge pipes 13, and the bottom edge of each Z-shaped discharge pipe 13 slides in contact with the inner bottom of the U-shaped bottom bracket 14.

[0128] In this embodiment, the U-shaped base bracket 14 is used to support multiple Z-shaped discharge pipes 13 to prevent them from falling off.

[0129] Example 6

[0130] like Figure 1-15 As shown, improvements are made based on Example 2:

[0131] Furthermore, the tillage component is a tillage floor 15, which is inserted into the snap-fit ​​groove 102. The bottom side of the tillage floor 15 has several tillage wing rods 1501 distributed at equal intervals. The tillage floor 15 is a preferred form of the tillage component.

[0134] When the positioning bolt 17 is tightened, the end face of the bolt 17 can abut against the side wall of the tillage floor 15 and form a clamping force, thereby positioning and fixing the tillage floor 15.

[0135] Example 7

[0136] like Figure 1-15 As shown, improvements are made based on Example 3:

[0137] Furthermore, a cover 8 is movably installed on the top of the seed hopper 7, and two sets of locking structures are installed between the cover 8 and the seed hopper 7, with the two sets of locking structures installed on both sides of the cover 8 respectively.

[0138] The lid 8 can be opened or closed on the seed box 7, thus facilitating the loading of the seed;

[0139] After the lid 8 is closed, a feeding slot 10 is formed between the seed box 7 and the lid 8, which allows for convenient feeding of the seed box 7 at any time during the planting process.

[0140] Specifically, hinges 9 are fixedly installed at both ends of the box cover 8 on the side facing the U-shaped traction frame 6, and the two hinges 9 connect and fix the box cover 8 and the seed box 7.

[0141] Both sets of locking structures include U-shaped connecting seats 18. The two U-shaped connecting seats 18 are fixedly installed on the opposite side walls of the box cover 8. Each U-shaped connecting seat 18 is movably installed with a locking tongue 19 via a pin.

[0144] In this embodiment, the two sets of locking structures can lock and fix the closed box cover 8 to the seed box 7.

[0145] In summary, the workflow of this utility model is as follows:

[0146] like Figure 1-15 As shown, when using this corn planting device for corn planting, the rotation of the moving wheel structure can synchronously drive multiple agitators, so that the multiple agitators can rotate synchronously with the rotation of the moving wheel structure. When the multiple agitators rotate synchronously, they can agitate the corn seeds in the hopper structure to assist in the discharge and unloading of the corn seeds.

[0147] Since each Z-shaped discharge pipe 13 can rotate on the material box structure, each Z-shaped discharge pipe 13 can be adjusted left and right according to the actual use. Multiple Z-shaped discharge pipes 13 can be closed or opened on the material box structure, so that the corn planting device can easily adjust the planting density when planting corn seeds.

[0148] like Figure 1-3 This demonstrates the use of multiple Z-shaped discharge pipes 13 in the retracted state of the corn planting device, such as... Figure 5-6 The image shows the use of multiple Z-shaped discharge pipes 13 in the corn planting device in the open state.

[0149] Meanwhile, when planting corn seeds, the corn planting device can simultaneously cultivate the soil through the tillage component to facilitate the planting of corn seeds.

[0150] Because the tillage component is mounted on the frame structure and can move up or down on the frame structure, the operating height of the tillage component can be easily adjusted.

[0151] The tillage floor 15 is a preferred form of tillage component. After the tillage floor 15 is positioned and adjusted, the positioning component can fix the tillage floor 15 in place.
