[0019] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0020] See also Figure 1-5 A manual corn seeder comprises a sowing tube 1 and a sowing device arranged on the sowing tube 1, wherein the sowing device comprises three perforated plates 7 arranged in a circular array at the opening position of the bottom end of the sowing tube 1, a control component arranged on the sowing tube 1 and controlling the three perforated plates 7 to move away from each other, and a feeding component arranged on the top end of the sowing tube 1 and feeding corn seeds into the holes. When the three perforated plates 7 are close to each other, they form an inverted cone structure with a small bottom end and a large top end surface.

[0021] like Figure 1-5 As shown, the corn seeds are directly placed in the feeding assembly, and holes are punched and pits are dug on the ground directly through the three perforated plates 7 arranged on the bottom end of the sowing tube 1. After the three perforated plates 7 dig holes on the ground, the three perforated plates 7 are driven away from each other by the control assembly arranged on the sowing tube 1, and at this time, the corn seeds are fed to the three perforated plates 7 through the feeding assembly, and the three perforated plates 7 are away from each other, so that the corn seeds located on the three perforated plates 7 are conveniently moved into the pits, that is, sowing is achieved, and the hole digging and sowing process can be completed conveniently, thereby improving the sowing efficiency of corn seeds.

[0022] Each perforated plate 7 is in a fan-shaped structure.

[0023] like Figure 1-5As shown, the three punching plates 7 are arranged at the opening position at the bottom end of the sowing tube 1 through a limiting assembly. The limiting assembly includes a slider 10 slidably arranged in a slide groove 9 opened in an inclined direction on adjacent sides of the three punching plates 7, and a rotating block 11 fixedly arranged on a side of the slide groove 9 away from the sowing tube 1. The control assembly controls the rotating block 11 to drive the punching plates 7 to move along the length direction of the slide groove 9. When the three punching plates 7 are driven away from each other by the control assembly, the three punching plates 7 will move along the opening direction of the slide groove 9, that is, the slider 10 slides in the slide groove 9, so as to facilitate the three punching plates 7 to move away from each other, thereby facilitating drilling holes on the ground and realizing the placement of Jiangyun seeds in the holes.

[0024] like Figure 2-5 As shown, the control assembly includes a control ring 12 movably penetrated in the wall of the sowing tube 1 and located above the three perforated plates 7, two control rods 4 arranged horizontally and with adjacent ends movably passing through the through groove and connected to the side of the control ring 12, and three transmission rods 8 whose top ends are rotatably connected to the end surface of the bottom end of the control ring 12 and whose bottom ends are respectively rotatably connected to the rotating block 11 in a one-to-one correspondence. The control ring 12 is connected to the top of the sowing tube 1 through a reset member and the three perforated plates 7 fit each other when the control ring 12 is located at the bottom of the through groove. After the three perforated plates 7 are driven into the ground, a pit can be formed on the ground. Then, by moving the control rod 4 in the direction of the fixed rod 2, it is convenient to drive the control ring 12 to move upward in the sowing tube 1, so as to facilitate the three perforated plates 7 to move upward through the transmission rod 8, so as to facilitate the three perforated plates 7 to move away from each other, so as to facilitate the corn seeds located on the three perforated plates 7 to move into the pit, so as to conveniently complete the pit digging and sowing process, and improve the sowing efficiency of corn seeds.

[0025] like Figure 1-5 As shown, a fixing rod 2 located above two control rods 4 is fixedly arranged on the top side of the sowing tube 1, and the reset member includes a fixing ring 5 movably sleeved on the tube body of the sowing tube 1 and the bottom end face is fixedly arranged on the top end face of the two control rods 4, and a limiting spring 6 movably sleeved on the tube body of the sowing tube 1 and the two ends are respectively fixedly connected to the fixing ring 5 and the fixing rod 2. After releasing the control rod 4, the elastic force of the limiting spring 6 sleeved on the tube body of the sowing tube 1 facilitates the control rod 4 and the control ring 12 to move downward, so as to facilitate the three punching plates 7 to approach each other through the transmission rod 8, so as to facilitate the sowing tube 1 to continue the operation of digging holes and sowing on the ground, and the digging and sowing process can be completed conveniently, thereby improving the sowing efficiency of corn seeds.

[0026] The feeding assembly includes a storage bin 3 fixedly arranged on the top end surface of the sowing tube 1 and with its bottom end inserted into the top opening of the sowing tube 1, a rotating disk 15 arranged on the bottom opening of the storage bin 3 and rotating through a rotating shaft, and a linkage member arranged on the top end surface of the control ring 12 and connected to the rotating shaft. When the control ring 12 moves upward, the rotating shaft and the rotating disk 15 are driven to rotate 90 degrees around the rotating axis of the rotating shaft through the linkage member.

[0027] The linkage member includes a control rack 13 whose bottom end is vertically fixed on the top end face of the control ring 12, and a control gear 14 whose end face is fitted on the bottom side face of the storage bin 3 and fixedly connected to the end of the rotating shaft. The control gear 14 meshes with the control rack 13.

[0028] like Figure 1-5 As shown, when the control ring 12 is driven to move upward by the control rod 4, the control rack 13 arranged on the control ring 12 moves upward, so as to facilitate the control gear 14 to rotate, that is, to drive the rotating shaft fixedly connected to the end face of the control gear 14 to rotate, so as to facilitate the rotating disk 15 located at the bottom opening position of the storage bin 3 to rotate, so as to facilitate the corn seeds in the storage bin 3 to pass through the gap between the rotating disk 15 and the bottom opening of the storage bin 3, so as to facilitate the corn seeds to move to the three perforated plates 7 through the inner wall of the sowing tube 1, so as to facilitate the placement of corn seeds in the pit while digging the pit when the three perforated plates 7 are controlled to move away from each other, so as to conveniently complete the pit digging and sowing process, thereby improving the sowing efficiency of corn seeds.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
