Detailed Implementation

[0020] Example 1, see appendix Figs. 1-3 An impact corn planter with straightness guidance function is provided. The lower middle part of the support shell 1 of the device is provided with a receiving groove 11. The receiving groove 11 extends into the support shell 1 to a certain depth without affecting the normal operation of the internal mechanism. The length direction of the receiving groove 11 is consistent with the length direction of the support shell 1. The receiving groove 11 is provided with a guide plate 2 that matches its size. The lower end of the guide plate is rotatably connected to the lower part of the receiving groove 11. The guide plate can rotate into or out of the receiving groove.

[0021] The guide plate 2 has a U-shaped bracket at its inner end, and there is an angle between the U-shaped bracket and the main body of the guide plate 2. The side support leg 23 of the U-shaped bracket has a bushing 24 at its end. A support shaft 12 is provided on the inner side of the receiving groove 11 and is fitted into the bushing 24. A hanging rod 13 is provided on the side wall of the receiving groove 11 inside the support shaft. A hanging hole 26 is provided in the middle of the inner end of the main body of the guide plate 2. The guide plate 2 forms a hinge structure with the support shaft 12 through the bushing 24, and the angle makes the lower part of the guide plate 2 form a bent structure, so that the hinge point is close to the bottom of the receiving groove 11. When the upper end of the guide plate 2 is pushed down, the downward pulling force of the spring can make it flip out of the receiving groove. After the guide plate is flipped up and put into the receiving groove 11, the spring can apply an inward pulling force to tighten and fix the guide plate 2 in the receiving groove 11.

[0022] The side wall of the receiving groove 11 below the outer side of the support shaft 12 is provided with a limiting rod 14. The two limiting rods 14 correspond to the two side legs 23 of the U-shaped bracket respectively. The limiting rods provide support for the guide plate. After the guide plate 2 is flipped down by the spring tension, it is basically in a horizontal state, which improves the guiding and distance setting effect.

[0023] The upper end of the receiving groove 11 is provided with a U-shaped notch, and a semi-circular groove 15 is formed between the U-shaped notch and the upper end of the guide plate 2. The semi-circular groove 15 is used to insert a finger, which facilitates the manipulation of the upper end of the guide plate 2.

[0024] When using the sowing device of this embodiment, the guide plate 2 is flipped out from the receiving groove 11. After the spring pulls downward, it is flipped out and is in a fixed state. At this time, the length direction of the guide plate 2 is the length direction of the sowing row. By observing the guide plate 2, it provides guidance for manual impact sowing and avoids the phenomenon of sowing deviation caused by human factors. At the same time, during the sowing process, the sowing distance between adjacent seeds can be controlled by the length of the guide plate 2 to ensure that the sowing distance is uniform and consistent, thereby improving the sowing quality and sowing efficiency.

[0025] Example 2, see appendix Figs. 4-6 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the guide plate 2 has a groove 21 inside along its length direction, and an extension plate 3 is slidably connected in the groove 21. The extension plate can slide in the groove 21 to adjust the overall length of the guide plate 2. The outer end of the extension plate 3 is provided with a pointing tip 31, which improves the accuracy of its guiding indication. Both sides of the upper port of the groove 21 are provided with limiting flanges 22 that support the surface of the extension plate 3. The limiting flanges restrict the extension plate 3 and prevent it from slipping out of the groove 21.

[0026] Both sides of the slide groove 21 are densely provided with several limiting racks 25, and both sides of the inner end of the guide plate 2 are provided with elastic rods 32. The end of the elastic rod is provided with a limiting head 33 that can be matched and locked between the limiting racks 25. Under the action of the elastic rod 32, the limiting head has elastic pressure and can be locked between the limiting racks 25. When the outer extension plate 3 is pulled, the limiting head 33 is pulled and will drive the elastic rod 32 to produce elastic deformation. The limiting head 33 can slide out from the limiting rack 25 to adjust the locking position, so as to realize automatic locking after the position of the outer extension plate 3 is adjusted.
